We designed and made this special-purpose machine for the automatic fitting of two O-rings on a basic part (RACK-BUSH) in the cycle in three seconds. The final product is intended for the automotive industry, where it is used as a bearing sleeve in the vehicle control system. This device comprises a turntable with five assembly positions and three specially designed vibrating feeders to automatically feed the components. In the first position, the manipulator takes a base part from the finishing beam and places the part in the product on the turntable. In the second position, the manipulator, fitted with a special ORG 85 gripper, collects an O-ring from the finishing beam, extends it and transfers it to the upper groove of the base part. In the third position, and identical manipulator carries out the same assembly procedure, fitting a second O-ring in a second groove. In the fourth position, assembly quality is camera-tested. In the fifth position, NOK products are separated from OK units based on the preceding camera test.
