A pcb shearing machine

Abstract

The invention relates to the field of board shearing machines, in particular to a PCB (printed circuit board) shearing machine. The PCB shearing machine comprises a machine body, a board limiting device, a board conveying device and a board recovering device, wherein the board limiting device is positioned in the front of the machine body and used for driving a squeezing plate to move via limiting air cylinders so as to limit a board; the board conveying device is positioned in the middle of the machine body and used for absorbing the board via a vacuum chuck and conveying sheared board from the right side of a shearing table to the left side of the shearing table via a combination of a screw and a slider to enable the sheared board to be sheared again; the board recovering device is positioned in the back of the machine body and used for driving a scraper plate to move by the aid of a first recovering cylinder and a second recovering cylinder so as to conveying the sheared board out of the board shearing machine. The PCB shearing machine has the advantages that the defect that a board needs to be conveyed manually in an existing PCB shearing machine is overcome, the board can be conveyed to shearing positions automatically to achieve repeated board shearing, and the sheared board can be collected automatically.

Description

Technical field [0001] The invention relates to the field of shearing machines, in particular to a PCB shearing machine. Background technique [0002] The shearing machine uses a reasonable blade gap to apply shearing force to metal sheets of various thicknesses to make the sheets break and separate according to the required size. The shearing machine is a kind of forging machinery, and its main function is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide special machinery and complete sets of equipment required. [0003] The PCB shearing machine is designed to use the PCB board to slide on the circular knife to cut the PCB board. This important design can ensure that the service life of the machine and equipment is prolonged during the use. But often in the process of using the PCB shearin...

AI Technical Summary

Problems solved by technology

But often in the process of using the PCB shearing machine, the tin plate will be broken, which will destroy the normal operation of the machine and equipment, and waste materials.

[0004] When operating on the existing traditional PCB shearing machine, due to the small and thin characteristics of the PCB board, the operator often directly holds the whole PCB board by hand and places it under the cutting circular knife, and the circular knife cuts the PCB board. , at the same time, the PCB board is transported to the right side of the circular knife by the circular knife. When a small part of the whole PCB board is cut off, due to specific needs, sometimes the worker takes the PCB board from the right side of the circular knife to the left side of the circular knife, and pushes it forward at the same time. Cut the PCB board again, because the whole process is operated by hand, which will cause safety hazards. At the same time, when the shearing amount is large, the materials scattered on the fuselage after being cut need to be collected manually, which increases labor. strength, in view of this, the present invention provides a device that can automatically transport sheet material, push sheet material, and recycle sheet material, thereby replacing manual work, avoiding potential safety hazards and reducing labor intensity
