Description

A high-efficiency and low-pollution electrical edging device for PCB boards

technical field

The utility model relates to the field of edge grinding of PCB boards, in particular to an electrical edge grinding device for PCB boards with high efficiency and low pollution.

Background technique

PCB circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves automation and production labor rates. According to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards.

PCB circuit boards are widely used. In the process of PCB circuit board production, it is necessary to grind the formed PCB circuit board body. Generally, the four sides of the PCB circuit board are manually edged by using an edger machine. , not only the efficiency is low, but also the dust is large, and the dust produced by edging is very fine, which is easy to inhale into the body of the staff, which brings hidden dangers to health and safety. Moreover, manual edging not only consumes manpower, but the accuracy of edging is poor. Some machines assist in edging, but they cannot adapt to different sizes of PCB circuit boards for edging, nor can they handle the dust generated. When multiple PCB circuit boards are fixed, the pressure on the PCB circuit board cannot be detected, which often causes damage to the PCB. The phenomenon of circuit boards produces more waste products and increases costs.
