Description

Technical Field

[0001] The utility model relates to the technical field of punching, in particular to a servo punching machine die. Background Art

[0002] With the refinement of smart devices, the quality control of circuit boards is becoming more and more stringent. The circuit board surface cannot have slight marks, lines, bends, etc. At present, the main molds used in the circuit board industry are stamping molds, which quickly combine the blades to turn the whole board into a single board. The process of taking the board is manual extraction. Although there are strict regulations on wearing finger cots, it is still impossible to completely avoid the traces left by human touch. In response to this situation, new automated machines such as HLC and Tongchuang complete the punching and taking of boards through suction throughout the process to avoid traces caused by human contact on the product surface. However, when the machine is sucking, the interference of the positioning pin will cause the board and material to get stuck. Utility Model Content
