Angle cutter for circuit board processing

Abstract

The invention discloses an angle cutter for circuit board processing, which comprises a supporting table, a cutting groove is formed in one side of the upper surface of the supporting table, the upper surface of the supporting table is divided into a wide surface and a narrow surface by the cutting groove, a liftable top is arranged in the cutting groove, and sliding grooves are formed in the two sides of the cutting groove. And screw rods are rotationally installed in the sliding grooves, nuts are in threaded connection with the screw rods, the nuts are fixedly connected with the ejector blocks, and a second chain transmission structure is connected between the lower ends of the two screw rods. According to the cutting device disclosed by the invention, the top block is arranged in the cutting groove, and the top block can ascend and descend in the cutting groove; during the initial cutting, the top block can support the part aligned with the cutting knife, so bending can be avoided during cutting; when the lowest circuit board is cut, the top block descends, and the situation that the top block affects the cutting knife to enter the cutting groove can be avoided. In conclusion, the circuit board can be better cut, and cutting deformation of the circuit board is avoided.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a corner cutting machine for processing circuit boards. Background technique [0002] The names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, super Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and visualized, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards may be referred to as printed circuit boards or printed circuit boards; [0003] Because circuit boards have different appearance shapes, when the circuit board is being processed, it is necessary to perform corner cutting operations on the entire c...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a corner cutting machine for circuit board processing, to solve the problem that the pressed part of the circuit board will be damaged when the cutting knife is pressed down when the circuit boards stacked in multiple layers in the prior art are cut. Problems with bending or even cutting deformation
