DEPRAG – For fully automated and efficient production
Vacuum cleaner housing assembly
Process Required:
Automatic assembly and test unit for vacuum cleaner housings
Mounting of the top and bottom cover of a vacuum cleaner, as well as differently integrated controls to increase the reliability of the process.
The automatic production process includes a repair workstation, which is integrated into the system. There, the operator decides whether rework is possible or whether the part is completely rejected.
Manual retightening is verified by integrated sensors: without the rework step, the system does not release the rejected part for further processing. VORWERK also chose a DEPRAG assembly system for mounting the telescopic handle.
Step 1:
The pre-assembled module (upper and lower housing) is automatically transported on a conveyor to the assembly unit.
Step 2:
After receiving the communication start signal from the conveyor, the elevator takes the part, which is now held horizontally by two slides, from the conveyor.
Step 3:
Positioning control and bellows tightness testing (vacuum test). If the bellows are not tight, the objectionable module is automatically unloaded and transported to the repair workstation, which is integrated into the system.
Step 4:
Presence control of the cable hook
Step 5:
Turn the switch, which will subsequently control the vacuum power of the unit, counterclockwise to position 3. This step is performed by means of a Screwdriver Function Module in underfloor execution, which is equipped with a MINIMAT-C Screwdriver spindle. is equipped with a MINIMAT-C Screwdriver spindle. The screwdriver switches off automatically when the torque of 1 Nm is reached. Defective parts are sent to the repair shop.
Step 6:
During the switch position test, nine MINIMAT-C inline screwdriver shafts, type 347C-528-31, simultaneously assemble two different screw types for tightening. Verification of the correct torque is performed by the integrated strain gauge transducer . Dual depth probing, provided for each DEPRAG screwdriver shaft, offers additional process reliability . Defective parts are sent to the repair shop.
Step 7:
The properly assembled housing is released and transported out of the system while, at the same time, the next 9 screws are automatically fed by the Vibratory Feeder .
