Abstract

The present invention relates to a kind of a punching mechanism actuated by a cam for flexible printed circuit boards, or the like. It is composed of a driving device, a plate cam, a follower, an upper punch guiding frame, a lower punch guiding frame, a flexible unit, and a punch. Rotated by the driving device, the plate cam commands the follower to move downwardly, which further pushes the upper punch guiding frame and then the punch downwardly. The flexible unit installed between the lower end of the upper punch guiding frame and the upper end of the lower punch guiding frame provides the restoring force needed for the punch, the upper punch guiding frame, and the follower to move upwardly. In such a way, the punching position and speed can be controlled.

Referring to FIG. 5, the mandrel of the rotating device 10 continues to rotate. As the eccentric outer surface of the flat cam 12 adds the restoring force of the elastic body 22, the punch upper seat 18 and the follower 14 move upward. It moves, and because the second slot 182 in the punch upper seat 18 abuts against the clamping head 241 of the punch 24, when the punch upper seat 18 moves upward, the punch 24 moves upward. Then, the flexible circuit board 40 is moved, and when the mandrel of the rotating device 丨 0 is continuously rotated, the punching action shown in FIG. 4 and the restoring action shown in FIG. 5 can be performed again. The advantages of the present invention are as follows: 1. The use of a flat cam can reduce the lateral force generated by the punch, reduce the gap between the punch and the die, and improve the burr problem that may occur on the flexible circuit board. 2. The rotation speed of the flat cam can be improved by increasing the speed of the servo motor 'to shorten the processing time at a higher punching rate' to increase production capacity in the South. 3. By adjusting the center of gravity position of the flat cam, the dynamic performance of the system can be stabilized.
