A pcb board automatic shearing machine and its control circuit

Abstract

The invention relates to the field of electric PCBs, in particular to a PCB automatic shearing machine and a control circuit thereof. The machine comprises a transverse cutting unit for transversely cutting PCBs, a vertical cutting unit for vertically cutting the PCBs, a machine body for accommodating the transverse cutting unit and the vertical cutting unit and providing moving space to the PCBs, a bottom stop device for limiting the bottoms of the PCBs, and a top stop device for limiting the tops of the PCBs. The control circuit comprises a control unit, a pneumatic unit, an electric unit, a sensor unit and a data statistics unit. The PCBs have no need to be pushed by human hands in the cutting process, and only depend on self gravity effect to downwards move to realize self transverse and vertical cutting; and compared with a traditional board shearing machine, the board shearing efficiency is improved, and the condition of hand injury caused by careless contact with a cutting tool of the board shearing machine is prevented.

Description

technical field [0001] The invention relates to the field of electrical PCB boards, in particular to a PCB board automatic shearing machine and a control circuit thereof. Background technique [0002] The shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. It uses the moving upper blade and the fixed lower blade to apply shearing force to metal sheets of various thicknesses with a reasonable blade gap, so that the sheets are broken and separated according to the required size. [0003] Existing PCB board shearing machines often use horizontally arranged upper blades to cut PCB boards. Before cutting PCB boards, manually place a piece of PCB board directly below the upper blade, and then start the machine to make the upper blade cut. Horizontal cutting movement, so that the PCB board is cut into a specified size. During the whole process, people need to hold the PCB board continuously, push the...

[0003] Existing PCB board shearing machines often use horizontally arranged upper blades to cut PCB boards. Before cutting PCB boards, manually place a piece of PCB board directly below the upper blade, and then start the machine to make the upper blade cut. Horizontal cutting movement, so that the PCB board is cut into a specified size. During the whole process, people need to hold the PCB board continuously, push the PCB board continuously, and change the orientation of the PCB board from time to time to meet the horizontal and vertical directions. The cutting operation is time-consuming and laborious, which reduces the cutting efficiency of the PCB board, and when the PCB board is small, the human hand is very close to the blade of the shearing machine, so there is a hand injury caused by accidentally touching the cutting tool of the shearing machine. possibility of injury
