PUNCHING MACHINE WITH 4 DRIVING AXIS FOR MULTILAYER PRINTED CIRCUIT BOARD

摘要

The present invention relates to a punching machine with 4 driving axes for a multi-layer printed circuit board, which can prevent generation of Burr during hole processing using a punching method instead of a prior drilling method, and can perform efficient work by comprising four hole processing axes. For this, the punching machine of the present invention includes: a transportation unit which transports a circuit board in a Y-axis direction of a center table straightly to manufacture the multi-layer printed circuit board; two pairs of XY-stages which comprise an X-stage moving in an X-axis direction and an Y-stage moving in a Y-axis direction on the X stage, and are located below the center table, and are arranged at left and right sides of the front and the rear of the center of a transportation line of the transportation unit; and four X-ray punching modules which are fixed on the Y-stage of the XY-stages, respectively, and detect a guide hole mark formed on the circuit board and then punch the guide hole mark to form four guide holes at the same time.
