Description

Fully automatic PCB splitter

technical field

The invention relates to the technical field of PCB splitting equipment, in particular to a fully automatic PCB splitting machine.

Background technique

With the continuous development of electronic technology, lamps are used more and more widely in our lives. One of the core components of lamps is the printed circuit board. In order to increase the output of printed circuit board (commonly known as PCB) manufacturing and the speed of the plug-in machine production line, PCB boards are usually designed in the form of multiple connections, which will be divided into many smaller single PCB boards in the final product. In order to facilitate the division of boards in the division process during the production of multi-unit PCB boards, V-shaped grooves or stamp holes are generally opened at the border. This V-shaped groove is the V-CUT groove. When using multiple PCB boards with slots, most of the existing splitters use a knife-moving scheme to split multiple PCB boards. However, the prior art has the following disadvantages:

1. The PCB board loading and unloading method of the knife-feeding scheme is manual, and it cannot automatically cooperate with the multi-unit PCB board loading and unloading, which greatly reduces the efficiency of the board-dividing operation. Since the multi-unit PCB board is loaded and unloaded manually, In the process of loading and unloading, it is very easy to cause hidden damage to the multi-unit PCB board, resulting in low yield and economic loss. It is also difficult to achieve seamless connection with the existing PCB board production process by manual loading and unloading;

2. When splitting high-precision PCB boards, the board splitting machine using this scheme often causes inaccurate positioning of the PCB board, causing internal damage and greatly reducing the yield of split boards.
