Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a punching mechanism for a four-layer half-hole plate. Background Art

[0002] Punching operation is an essential step in the manufacturing process of printed circuit boards. It is mainly used to connect the upper and lower layers of the circuit board to achieve vertical crossing of the circuit. In recent years, the four-layer and a half hole board has become more and more popular in the industry for its excellent performance and wide application fields. The four-layer and a half hole board is a special PCB design, which is usually used in electronic products that require high-density wiring. It contains four layers of conductive material and has a row of semi-metallized holes on the edge. These holes are used to solder small carrier boards or modules to the main PCB. This design allows for smaller size and more compact layout while providing the necessary electrical connections. In the production process of the four-layer and a half hole board, punching equipment is particularly important.

[0003] Most of the current punching equipment uses mechanical punching, mainly including a press, also known as a punching machine, and related punching dies. The press and the die apply external force to the four-layer and a half hole plate to cause it to produce plastic deformation and fracture, so as to achieve the purpose of punching. The four-layer and a half hole plate punching equipment currently used is mainly used to punch a type of four-layer and a half hole plate. When punching different types of four-layer and a half hole plates, the corresponding punch and die need to be replaced, but the punch and die in the current punching equipment are not easy to replace, and there is a problem of difficulty in replacement. In addition, these devices also lack an effective way to handle waste during the punching process, and often require additional manpower for cleaning, which is more troublesome. In view of this, we propose a punching mechanism for four-layer and a half hole plates. Utility Model Content
