Highly flexible cleaning system with fully automated loading/unloading and assembly processes

All components (various types of shafts and cams) are fed to the system in blisters via a plastic chain conveyor. An ABB robot with spring-loaded grippers is employed for tension-free pick-up and placement of the work pieces.

At the alignment station one shaft type will be aligned to its specified position, and identified via DMC code.

At the sensor ring assembly station the magazine-loaded sensor rings are separated, and then mounted onto the shafts in their respective, specified angular positions, depending on the individual shaft types. Each joining/assembly process is monitored by means of a force/distance measuring system, and recorded accordingly.

A robot removes the assembled components from the joining/assembly station – good parts are placed on the shuttle system of the cleaning system, bad parts on the reject conveyor.

The cleaning process is specified as a 3-bath technology with 5 chambers, and subdivided into 3 wet and 2 dry processes:
cleaning → rinsing 1 → rinsing 2 →
hot-air drying → vacuum drying

After cleaning, rinsing, and drying the parts in the course of the cleaning process, a second shaft type will be identified by means of a DMC code – good parts are fed to the bearing assembly station, bad parts are ejected separately.

At the bearing assembly station the magazine-loaded bearings are separated, and then mounted onto the shafts in their respective, specified positions. Each joining/assembly process is monitored by means of a force/distance measuring system, and recorded accordingly.

A robot removes the assembled components from the joining/assembly station – good parts are placed in the coded blisters, bad parts are ejected separately.

All components (various types of shafts and cams) are fed out of the system in blisters via a plastic chain conveyor.

Process steps
