The manual devices are necessary for the production of prototypes for the production of first samples as auxiliary means for starting the preproduction of a product for the lot production of variants of types with small lots and for making products in a very small number. 6 Our basic competences in the field of devices include the production of the following The equipment can be integrated as tools or supports for components in a manual operation post, a semiautomated or completely automated installation. The equipment characteristic is that it is used or can be replaced as a complete module. 1 3 2 4 5 7 Gripping units Contacting units, for example adapter of needles Joining and assemblage devices Stamping and bending units Welding stations Cleaning and suction stations Screwing up units Lubrication devices Dosing systems Milling and drilling units Marking and inscription devices, for example hot and cold stamping units, crayon marking units, label printers, laser engraving systems, stamping units for verification codes, Ink Jet printing systems, needle stamping units, etc. Testing units, such as image processing systems, speed – force – track testing stations, angle – engine torque – speed testing units, units for the verification of diameter and concentricity, stations for tightness verification, high voltage testing units 8 10 9 http://youtu.be/QoRURPSb3wg 6 The devices for different applications, such as 1 Manual joining devices 2 Semi-automated pneumatic assemblage device 3 Manual contact and verification device for the cylinders of ignition switches 4 Automated contact and verification device for the cylinders of ignition switches 5 Assemblage device for photoelements 6 Semi-automated cleaning station for double switches with ionized air 7 Welding device for laser welding automatic machine 8 Semi-automated contact and verification device for the ignition switch of the engine hood 9 Manual bending device for diodes 10 Manual assemblage and verification device for the laser distance sensor 7 Manual operation posts Refined help for the partial automation of processes The assemblage, verification and measurement devices and the related material flow system will be manually and favourably connected from the point of view of costs with the manual operation posts. 3 The condition for all posts on the chair and afoot is the ergonomic structuring of the workplace, according to DIN 33400 ff and DIN ENV 26 385 Orientative sizes for the necessary space We produce manual operation posts in different variants: Mechanics for cabinets, in which assemblage processes are executed, respectively verification processes, as well as outside and inside the cabin. 1 Mechanics for double cabinets and mechanics for rotary disks in which processes are executed simultaneously outside and inside the cabin. 2 Mechanics for lifting doors in which the technique of processes is executed mainly inside the cabin. 3 Open mechanics The processes being executed exclusively manually, with electrical instruments and/or tools. 4 Complex mechanics In which different processes are executed in different devices, with different safety doors (here sliding door and the mechanics of cabinets). 5 Length of action mm 400 Other options for all manual operation posts are mentioned above, namely construction with console or box, height adjustment of the working bench, support for feet, visual obturators, drawers, assemblage portal with workplace illumination, track arm with rails for electrical tools suspended with swing, energy supply channel, support plate for tools and gripping device. 1 200 4 3 2 4 0 Gripping space 200 800 600 400 200 0 200 400 600 800 mm 2 1 5 8 9 Automatic machines with rotary transfer Compact and advantageous solutions for the automation of processes The automatic machines with rotary transfer and manual equipping and controlled by an operator are used at the production of lots with small quantities. These increase the automation degree and thus costs per piece for the produced unit are reduced. The automatic machines with rotary transfer have the advantage of being built in a compact way, they require a reduced necessary space and also have very reduced switching-over cycles. By comparison, the costs of investment in equipping the machines are also reduced. The automatic machines with rotary transfer with semi-automation – we are also talking about hybrid assemblage – are used by an operator who manually introduces the components to be assembled, namely the components to be verified. After introduction, a sensor determines if the component is correctly placed and the rotary disk will guide after a station, after the safety door was manually closed. Instead of a safety door, a light curtain can also be used, which will guide the rotary disk further, immediately after the operator leaves the area monitored by the light curtain. The automatic machines with rotary transfer can be completely automated by manipulating the location, for example by a robot. At the illustrated automatic machines with rotary transfer, the component to be processed, respectively the sample, are manually placed in the support for components on the rotary disk. In a second station will be carried out for example the assemblage process. In a third station takes place the testing process and in a fourth station will be marked the component to be processed and/or it will be automatically placed on a taking-over band. 10 11 Transfer systems for supports of components High power, smart and flexible systems for different requests. The transfer systems for supports of components are distinguished by a larger flexibility. This means that the processes from the assemblage and verification line can be removed, namely completed. Moreover, the assemblage and verification processes of great variety can be also carried out with the transfer systems. It is possible a combination of manual and fully automated stations inside the production line. 1 The selection of the support for components allows higher sizes. The particular conditions have an important role in installation design. The complex assemblage sequences require a larger flexibility when selecting systems and structuring design. 3 The transfer systems for supports of components are distinguished by the following installation designs: System with connection in series: Square construction System with by-pass connection: Mixed system: A2 A1 A3 A4 Round construction U-shaped construction The automation of verifications The samples delivered on pallets or on supports for components will be taken over from the conveyer band in the verification station by a portal robot. There, the components will be connected, tested and the measurement of the introduction/extraction force and rotation moments will be carried out. 1 Lifting assemblage for lines The conductor pads for exhaustors will be placed manually on the supports for components and then they will pass through a heating station, plasma cleaning station, assemblage station for arm lifters with automated label supply, as well as a Pick&Place unit with grabber for needles and a final pressing unit. 2 The assemblage of the operation field for the door The operation fields for the door will be assembled in different variants, in manual and automated stations, namely cleaned, tested, screwed up and marked. 3 Module assemblage At this assemblage system for supports of components, the individual components will be placed and assembled manually in the fastening places on the support for components. In different stations, the components will be tested and adjusted. In the last stations takes place the thermal welding of the entire subassembly. 4 2 4 12 http://youtu.be/FzWDQXm7Cw8 13 Manual manipulation systems For the complete automation of processes »Catch things, from the place they can be picked up« Epiktet (50–138 A.D.) The manipulation technique is the material means or devices which transport the material flow from one post to another. In the automation technique, robots are used for completely automating the assemblage and/or testing process. For this are used loading and unloading stores in order to maintain the buffer of components. Portal axis robot In the right part of the image you can see two portals with 3D arm with 5 axes each. X-Y-Z axis will be completed by a rotation axis to which is connected another linear axis. Portal with 2D lines: http://youtu.be/li9qUrRkpLE 3D arm portal with 4 axes: Within this completely automated assemblage process, the injector is assembled in the nozzle casing, by means of two sorting containers and a storage bin of components, as well as a 2D line portal with pneumatic grabber. 3D space portal with 3 axes: In the figure below it is illustrated a 2D line portal with double, pneumatic grabber. The robot with articulated arm exists, for example as robot with 5 and 6 axes with 5, namely 6 rotation axes. In the left part of the image you can see a WIG welding automatic machine using a robot of 6 axes. 14 http://youtu.be/PRqSUaVToiI http://youtu.be/EHMNM43UOd4 15 Test stands Installations for the verification of products or other components The life duration ... The test stands are important means for assuring the quality, for reducing at minimum the losses of products. The life duration of products can be presented tipically in a diagram, the so-called »duck curve«, as failure rate, depending on the life duration (see the chart). determines the period in which a technical product can be used without replacing the central components or a complete failure. In order to ensure the quality, it is important to test the mechanical and electrical characteristics of the new products even from the time of their development. For this purpose, test stands are used for determining the life duration. For this, the samples are mechanically fixed in supports and Examples 1 Test stand for electric tools 2 Test stand for switches of electric tools 3 Test stand for safety switches 4 Test stand for safety switches for hinges 5 Test stand for screwdrivers exposed to a permanent alternating request (for example rotation moment and/or traction force – compression force). This happens uninterruptedly, usually for a period of up to three months. Within this period, the parameters to be measured will ve recorded (for example moment of rotation, force, speed, track, current, temperature). Incircuit Tests ... End of Line Tests (EOLT) ... are testing procedures by which the (electronic) pretested product is subject to an intermediary verification before continuing the production, namely assemblage. By intermediary verifications, the products that are not good are evacuated before reaching the final process (final assemblage or final production). The intermediary verifications will be carried out for example at conductor plates and even at modulary equipped conductor plates. The adhesion problems, errors at components, including couplings, are tested. are testing procedures in production by which the 100% functioning of newly produced products is verified at the end of the production process. Also, these serve for ensuring the quality, their name coming from the fact that most automated test stands are directly at the end of assemblage and production lines, from spatial point of view. 3 »Bathtub« diagram For presenting the failure rate of a product depending on its life duration λ (ppm) t = time in years λ = failure rate in parts per million Failures due to ageing Real error rate Constant of accidental errors Previous failures t (anno) 2 1 16 4 5 17 Automation for permanent tests in the temperature panel Stress-Screening Stress-Screenings are the tests concerning the life duration, in which the ageing of products is strongly accelerated by using quick and extreme modifications of the temperature (Temperatures of –70°C up to +250°C). Hot stamps, rooms for high temperatures and temperature testing cabinets are used for this purpose. It can be verified either in constant temperature conditions or in conditions of temperature that modifies in time. Through this testing procedure, the development time of a product until it will be ready for the lot production is reduced, along with the simultaneous reduction of costs. 1 Examples 1 U nit of pressure sensors in the temperature room 2 U nit of pressure sensors in the temperature cabinet, with the use of an HF room 3 A djustment unit for permanent tests in the temperature panel 4 R otation verification in the room of high temperature 5 V erification of the position adjustment switch for the temperature panel 6 E lectro-motive unit in the room of high temperature 7 V erification of the step selection switch in the temperature cabinet, using X-Y linear axis portal 4 3 5 6 7 2 18 19 Electrotechnique and software The brain and neurological centre of the machine A part of the automation technique includes the project and orders. Here are included the hardware design, the construction of the control panel, the installation cabling, the software creation and activation of the automation process. Depending on the input sizes (for example the position of a button or a sensor) the output sizes will be modified by using an actor (for example valves or engines). The construction of distribution installations Electric constructions with electric scheme Software The control panels are created at random sizes, from the individual component to the lot production. This usual construction software allows a documentation which can be used without problems at the extensions of machines and/or modifications of machines and can be adapted – of course complying with the current norms for electric safety. The software of the machines is created on Hard- and Soft PLCs, as well as on PCs. For this, we use orders from Siemens (S7) and Beckoff. The PC-based software is created with LabVIEW from National Instruments and Microsoft Visual Studio. 0 13.9/ 1 L1 11.8/ L2 11.8/ L3 2 3 4 5 3 5 13 2 4 S/L2 Netz BERG T/L3 PE PE 4mmý R/L1 U1 3~400/ 30.1 480V; 3,0kW 2,5mmý 480VAC CN3 ER 0VDC PBE iderst 9 42 43 spannu 44 ng and Motor Geber CN4 CN2 112 BN 03R07 Ballas 27 Ohm twider /200W/ stand 0,75 m Ans chluák abel 2W1 VW3M51 01R100 10m 4x1,5 +2x1 2XS1 8poli ngsste ger cker CONINV SF7ES ERS 1N8A8L B2 L1 L2 L3 YEGN WH ale 110 You can receive competent assistance including after the activation carried out by us.

AOI system with two high resolution cameras and double line light within a dark cell. Measuring points Measuring technique Electric safety equipment Programmable logic controllers IPC orders AOI systems deals with determining the physical sizes, such as length, force, temperature, current, voltage and resistance, many times depending on time. These values are determined through special measuring devices, selected for that use case. The registration and processing of this multitude of measuring data is carried out through IPC orders (Industry Personal Computer). are redundant at assemblage, do not have errors and take over the control functions from the point of view of the safety technique, forming the interface between human and machine. This takes place under the form of protection equipment such as safety light curtains, operation with two hands, emergency stop button, etc. (PLC) are digitally programmed and are used as individual device or modular structure (feeder, main processor, E/A cards, interface cards, actuating mechanism controller) in the control panel. will be programmed with programming languages such as LabVIEW or C-Sharp. These can have extensive additional functions, such as complex visualizations, protocols and statistics (see also the paragraph Measuring technique). Complex automatic machines with a variety of functioning sequences for which are not used additional functions, such as the above-mentioned visualizations, protocols and creation of statistics, controlled by PLC. The complex automatic machines for which are used the above-mentioned additional functions receive besides PLC an IPC subordinated order. The simple automatic machines for which are used additional functions receive only an IPC order. The quality of the component to be processed is evaluated with an automated optical inspection. By using an image processing system – executed with camera, lens and illumination under a darkening hood – different parameters are evaluated, such as light brightness, contrast and colour and a limit value is defined for the good/bad evaluation. The existence and correct positioning of defective components can be detected, being determined including the cracks from components. Also, it is possible to recognize the writing and symbols, as well as to determine the lengths and width. The hardware for the measuring technique is usually integrated in a separate control panel for the control technique. 22 Mobile touchscreen for a machine order Fixed, simple operation panel, for machine order 23 Special machines Individuality is our standard Many technical production processes are not carried out through conventional automation solutions.
