Abstract

The apparatus provides a sufficient fastening to modules, inserted in the printed circuit cards before wave soldering, by crimping of selected pins after insertion. Insertion head 1, having inserted module 2 in board 3, registers with a crimping head. This head includes two jaws, pivotal around their axis 5 and a biasing spring 6. The crimping head is mounted on a rotating arm 7 which can be moved by a knuckle joint 8 actuated by pneumatic actuator 9 provided with a piston 10.

Module Crimping Apparatus

The apparatus provides a sufficient fastening to modules, inserted in the printed circuit cards before wave soldering, by crimping of selected pins after insertion. Insertion head 1, having inserted module 2 in board 3, registers with a crimping head. This head includes two jaws, pivotal around their axis 5 and a biasing spring 6. The crimping head is mounted on a rotating arm 7 which can be moved by a knuckle joint 8 actuated by pneumatic actuator 9 provided with a piston 10.

When a module 2 is inserted, a control signal is applied to actuator 9. Piston 10 makes a right-hand movement. Articulation 1 1 of knuckle joint 8 follows that movement which results in the lifting of arm 7 and of the crimping head.

Jaws 4 are provided with surfaces, which upon the lifting of the crimping head, contact the pins to be crimped. Lifting continues and jaws 4 are urged by spring 6 to bend the pins. At the completion of crimping, piston 10 operates to the left, which lowers arm 7 and the crimping head.

During the crimping step, no pressure is applied by inserting head 1 on the top of the module. In addition, spring 6, which urges jaws 4, allows them not to damage a module 2 in case of improper insertion.
