The air-conditioning systems used in motor vehicles are complex systems with many technical extras. For example, air flows are led through various ducts. Louvre modules are used to control the air flows.
A loosely linked assembly line with 12 work stations is used to manufacture the various types of modules from 6 component parts.
Assembly is performed at a cycle time of 3.5 seconds which is extremely short for a goods carrier system.
The individual parts are supplied both as bulk material and in correctly orientated blister packs.
In order to minimise conversion times, a work piece carrier (WT) was developed for two different types of lamella, so that only two WTs would be needed to handle three types of lamella. Each one bears a code carrier. This ensures identification in each work station.
The database control system records production progress, stores the values measured in the testing station, and identifies reject parts. Faulty carriers are registered immediately, not processed any further and emptied later. In the NOK part removal, faulty parts are placed into various reject bins according to error class by the removal handling.
A fully automated palletizer and a step conveyor also go to make up the whole plant.
Plant control is visualised by an industrial PC. The two flat touch screens are easy to service, one is attached to each of the long sides of the plant, and they can be slid along. The display is made exclusively via a graphic user interface.
Following the assembly, the dimensions are tested by a path-measuring system. Several turns are initiated to ensure that the lamellas are moving freely. The presence of the coupling rods is checked at the same time. This is followed by testing the torque.
The flow measurement measures the air-tightness of the louvres. The measurement is made at a defined overpressure by a mass flow gauge. Part type, manufacture number, and date and time are printed by an ink jet printer to identify every part.
