Description

Technical Field

[0001] The utility model relates to the technical field of punching, in particular to an anti-vibration punching mechanism for flexible circuit boards. Background Art

[0002] When processing inner circuit boards / flexible circuit boards, in order to assemble the final circuit, it is necessary to bond each independent circuit board together with high precision. Therefore, there is an increasing need to mark and punch holes on each independent inner circuit board layer, usually by punching holes at precisely determined positions on the printed circuit board to form these marks and holes.

[0003] In order to complete the precise positioning of the inner circuit board, a camera is usually used for precise positioning. However, the cameras of some punching devices move with the die. However, the punching of inner circuit boards belongs to the field of precision machining. Since vibrations will be generated when the camera moves, the detection accuracy will be affected.

[0004] For example: The punching device, stamping platform and punching method disclosed in Chinese Patent Application No.: CN202110890416.5. Specifically disclosed is that "the upper die assembly further includes a CCD camera. There are multiple CCD cameras, and each CCD camera is distributed in each corresponding area of the upper template; the camera takes pictures of the workpiece on the workbench and grabs the position of the workpiece on the workbench. When the workpiece enters the workbench, the CCD cameras in each area grab the target of the workpiece on the workbench, calculate the coordinate difference between the current target coordinate and the reference target coordinate, calculate the difference between the current target and the reference target through the host computer, and then adjust the position of the workpiece on the workbench through the XYY adjustment structure to make the target on the workpiece coincide with the reference target, thus completing the positioning work". The CCD camera moves up and down synchronously with the upper die assembly. This design causes the CCD camera to be vibrated during the processing, which will in turn affect the detection accuracy.
