Fully closed-loop pcb board laser automatic board splitting machine and board splitting method

Abstract

The invention provides a fully closed-loop PCB board laser automatic board splitter, comprising a laser board splitter, a laser cutting mechanism, a circular automatic feeding mechanism, a snatch mechanism, a control system and an image recognition system. The circular automatic feeding mechanism is installed on the laser splitter, and the laser cutting mechanism, snatch mechanism and image recognition system are located above the circular automatic feeding mechanism. The circular automatic feeding mechanism is used to transport the jig to the snatch mechanism, and the jig is used to load the PCB board. The snatch mechanism is used to lift the fixture to the focal point of the laser cutting mechanism. The image recognition system is used to take pictures of the PCB board and transmit the photo results to the control system. The control system controls the laser cutting mechanism to assemble the pieces together according to the photo results The PCB board area on the PCB board is cut, and the snatch mechanism is also used to place the jig on the circular automatic feeding mechanism for recycling. The invention realizes full automation of laser board splitting, can effectively reduce labor intensity and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of PCB board processing, in particular to a full-closed-loop PCB board laser automatic board splitting machine and a board splitting method. Background technique [0002] Generally, the PCB boards used in electrical appliances are relatively small, which is caused by the need for miniaturization and miniaturization of electrical appliances. A large PCB board, and finally these large integrated PCB boards are divided into small unit PCB boards, which is the sub-board of the PCB board, for example figure 1 The PCB board can be split into four small PCB boards. The process of dividing the board is to cut off the connection point 1-2, and at the same time separate the side board 1-1, and finally get four small PCB boards. [0003] Conventional PCB board splitting methods use machine milling to split boards. This method is transplanted from mechanical processing, but there are many problems: [0004] 1. The pr...

Problems solved by technology

[0004] 1. The processing dust will pollute the PCB board, so the separated small PCB boards need to be cleaned twice, and the increased process also increases the processing cost;

[0005] 2. The vibration generated in the milling process may damage the internal copper foil of the multi-layer PCB board, which will cause the yield rate to not be guaranteed at 100%;

[0006] 3. A specific fixture is required to target a specific PCB board, so the cost of the fixture is too high

However, the initial laser splitting is actually a marking machine mode splitting, and it belongs to a single-piece production operation, with relatively low efficiency and high labor intensity.
