WSM Automation Schraubstation

WSM Stationary Screwdriving Unit / Screwdriving Station
Assembly of components for car radios and navigation systems as well as testing thereof.

The assembly station is enclosed by a safety housing.
The service doors are equipped with monitored safety switches with interlocking function.
During automatic operation, the doors are locked and can only be opened during an automatic stop or in manual mode by pressing the door button on the control panel. Automatic operation cannot be started while the doors are open.

Process Sequence
The station is loaded with the pre-assembled module via the transfer conveyor.
Below is a description of the automatic station’s work steps when processing a workpiece carrier (WT).
Under normal operation, all three stations run in parallel.

- Positioning of the WT with the pre-assembled module in station 2.1

- Lowering of the carrier with the scanner and vision sensor
- Scanning the 3 codes (front panel, front PCB, SD PCB), cross-checking with the database
- Checking correct latching of the FFC in the connector
- Raising the carrier and lowering the WT onto the conveyor
- Positioning the WT with the pre-assembled module in station 2.2
- Positioning the screwdriver and fastening the front PCB
- Lowering the WT onto the conveyor
- Positioning the WT with the pre-assembled module in station 2.3
- Lowering the light protection cover and contacting, approaching the carrier with the test sensors from below
- Type-specific testing of the illumination of SD + CD slots and buttons
- Function test of the CD eject button
- Lowering the WT onto the conveyor – proceed

If errors occur during testing, they are displayed on the screen and, if possible, can be corrected.
To do so, switch to manual mode and open the doors. After repair and restarting automatic mode, the WT will be retested in the station.
If repair is not possible (e.g. screwdriving error), the WT will be marked as NIO (Not In Order) in the control system and will not be processed further.
Manual NIO marking and removal is also possible.
