With its easily exchangeable components, the system is especially suitable for the production of different product variants. Assembly and marking activities along with testing tasks, such as functional tests, vision systems, ICT/boundary scan and HF test or parts ejection can be combined as required. The advantage of the rotary index table design is also that it requires little space.
Designed as ESD-compatible standing/sitting workplace with two-hand safety release:
Station 1 – Scanning the data matrix code on the PCB for traceability, cover assembly
Station 2 – Testing the coding of the high-frequency plug, screw length sensing, clicking the cover into place
Station 3 – Electrical tests: Contacting the HF plug, the three-pole “MQS” connector and the grounding screw
Station 4 – Reserve
Station 5 – Laser marking of test pieces
Station 6 – Marking check, unloading the fail parts with a vacuum gripper
Different modular tests can be performed at the individual stations of the rotary index table, for example:
– Measuring the quiescent and operating currents
– Testing the HF signal paths by means of HF network analyzer and LXinstruments HF switch units
– Verifying the diversity systems
– Testing the remote-controlled central locking and keyless go
– Flash programming of test pieces
To optimize the test period, the test tasks are distributed over several stations of the rotary index table.
Traceability, process interlocking and control software:
All stations of the rotary index table operate independently and communicate with each other via TCP/IP. The PLC controls the mechanical system and logs the test piece on the respective station by means of the serial number. The stations read all test and marking parameters from a MySQL database and then save the test results there.
The software which is available in several languages ensures complete locking of the production process from surface mount to AOI, ICT, assembly, final test, laser marking and packaging.
