Abstract

The invention relates to a grinding device, in particular to a board grinding device for PCB machining. According to the board grinding device for PCB machining, automatic grinding is achieved, the position of a circuit board is limited, feeding is convenient, chippings on a grinding plate are easily removed, and the ground chippings are easily adsorbed. According to the technical implementation scheme, the board grinding device for PCB processing comprises a bottom plate and an adsorption mechanism, wherein a grinding mechanism is arranged at the upper part of the bottom plate; and the adsorption mechanism is arranged in the middle of one side of the upper part of the bottom plate. According to the board grinding device, a special-shaped frame at the upper side is pushed to move downwardsto drive a second rack at the upper side and a brush to move downwards; a second gear drives the second rack at the lower side to move upwards, so that the brush at the lower side is driven to move upwards, the brush sweeps away chippings on the grinding plate, the residual chippings on the grinding plate are easily removed, and the cleanness, tidiness and normal operation of the grinding plate are ensured.

Description

technical field [0001] The invention relates to a grinding device, in particular to a plate grinding device for PCB circuit board processing. Background technique [0002] The board with many small parts installed in the electrical appliance is called a circuit board. Since the invention of the circuit board, it has played an important role in modern civilization. Semiconductor technology reflects the level of industrial modernization of a country and guides the development of the electronic information industry. Semiconductor technology The electrical interconnection and assembly must rely on the circuit board. In the process of PCB circuit board processing, polishing the PCB circuit board to make the surface smooth is also an important part. [0003] The existing PCB circuit board polishing technology is to fix the circuit board in a certain place, and use the equipment to drive the polishing board to move left and right to polish its surface. It varies from person to per...
