DEPRAG – For fully automated and efficient production
Press-in station for cylinder head caps with captive screws
Process Required:
Mounting station designed for feeding and press-fitting of safety screws (sleeve and screw combination) into the cylinder head cover of an automobile.
The complete cycle time is 25 seconds (including the time required for the operator to load the parts).
Assembly step 1:
Loading the cylinder head cover into the workpiece carrier and fully automatic feeding of 13 screws. Screw presence verified by ring proximity switches. Operator slides the sliding part fixture into the machine.
Assembly step 2:
The screws are presented by vacuum suction. 13 screws are individually picked up by vacuum suction and a pressure sensor verifies the pick-up process. The 13 press-in modules can be moved and positioned individually to ensure the correct depth of each individual screw. Assembly step 3:
Press-fit insertion of the screw-sleeve combinations with the control depth of each individual screw by using a cylinder limit switch. Assembly step 4:
If the cylinder head cover is assembled correctly, the sliding part attachment retracts automatically.
A faulty assembly must be recognized by the operator. Only then can the part be removed.
