Auxiliary Electronic Circuits for Testing Electrical Wiring

CreaSoft company creates software and hardware for automotive wiring testing. In the following illustration we can see a photograph of part of the wiring of a vehicle. As you can see the wiring is made up of a large number of cables with connectors at the ends. Wiring manufacturing companies such as Valeo or Lear design and assemble complex electrical wiring using connectors, terminals, electrical wire and other raw materials. The final phase of cable manufacturing consists of checking it. It is at this time that CreaSoft products intervene. In the following illustrations we can see two test boards, note how the wiring connectors are connected to the test bench counter connectors. These elements are called counterpieces.

Distributed Multifunction System RS485 or USB 1.1 for Testing Electrical Wiring

The purpose of the project is to check the wiring harness, this time the mechanical enclosure is not a rack, but cards located on plastic guides, thus providing greater versatility. In the following photograph we can see an example of different cards located in the guides and interconnected with each other. These systems consist of electronic cards controlled by the PC. Communication with this is done through the USB bus if there are high transmission speed requirements, or through the RS485 bus if long distances are desired in industrial environments. The general diagrams of these systems are presented below. The following illustration shows how the PC communicates with a USB hub (HUB), and this in turn does so with each CPU card. In total, a star topology network of up to 127 nodes can be implemented (typical of a USB network). Each CPU card can control up to 8 peripherals.

Putty Heated Pumps for OEMs Production Line

Date: 2000.Developed by ASM Dimatec.Clients: numerous vehicle manufacturers.Authors: Raúl Bartolomé Castro and other engineers.Contribution of Raúl: electrical designer. Creation of schematics in ePAN, selection of electrical elements and creation of electrical documentation.Market: automotive subsidiary.Product category: industrial machinery. The project consisted of heated pumps for the application of putty, which is applied at the junction between bodywork and glass as a sealing method. The pump is optimized for the extraction of very low viscosity fluids. All the hoses are heated, as well as the piston, valves, etc. The electrical control box is made up of PLCs, magnetothermics, electromechanical relays and solid…

Sheet Stacker for Ford Production Line

Date: 1999 - 2000.Developed by ASM Dimatec.Customers: Ford.Authors: Raúl Bartolomé Castro and other engineers.Contribution of Raúl: electrical designer. Creation of schematics in ePLAN, selection of electrical elements and creation of electrical documentation.Market: automotive subsidiary.Product category: industrial machinery. This system consisted of a press line and the sheet unstacking system. The de-stacking was implemented using a robot, which extracted the sheets from the pile and introduced them in the first press. The security criteria were very severe: Pilz security automatons and all wiring with an emergency mechanism. The project was selected to carry out an audit of the QS9000, which is…

Putty Glass Application for Seat Production Line

Date: 2000.Developed by ASM Dimatec.Clients: Seat.Authors: Raúl Bartolomé Castro and other engineers.Contribution of Raúl: electrical designer. Creation of schematics in ePAN, selection of electrical elements and creation of electrical documentation.Market: automotive subsidiary.Product category: industrial machinery. This machine consisted of applying putty to the car's rear window, made up of two well-differentiated blocks, one heated pumps and the other a Cartesian axle system for applying the putty. The most tedious part of the design consisted in the numbering of the terminals of the electrical cabinet, as well as the manual drawing of the same. In the illustration on the left you…
