Description

Technical Field

[0001] The utility model relates to the technical field of plate grinding machines, in particular to a PCB plate grinding machine. Background Art

[0002] PCB circuit board is the provider of electrical connection for electronic components. The production process of PCB board includes many steps, among which the grinding process is an important link, and the semi-finished PCB board needs to be sent to the grinding machine for grinding. The purpose of grinding is to remove the oxide layer on the surface of copper foil by physical method, so as to obtain a microscopically rough surface, so that the subsequent plating or coating is more reliable.

[0003] The patent document with the prior art publication number CN217513567U provides a PCB board grinding machine. It includes a pair of vertical plates, the top of the vertical plates are rotatably connected to multiple groups of rollers, and conveyor belts are connected through roller transmission. Multiple groups of conveyor belts are arranged at equal intervals on the rollers, and multiple groups of positioning columns are arranged at the top of the conveyor belts. The top of the vertical plates is fixedly connected to a top cover, and multiple groups of grinding rollers are rotatably connected through the top cover. Multiple groups of dust suction plates are suspended and fixed at the bottom of the top cover, and the top of the dust suction plate is connected to an exhaust fan through a dust suction pipe. One side of the top of the vertical plates is fixedly connected to a support platform, and the support platform is fixedly connected to multiple groups of export plates, and the other end of the export plate is obliquely inserted between the intervals of the conveyor belt. The beneficial effects of the utility model are: no clamp is needed for clamping, only positioning holes need to be drilled on the PCB board, which saves production costs, is more convenient to use than the clamp, and improves production efficiency; the export plate can automatically break away from the restraint of the positioning column on the conveyor belt, which is convenient for operation.

[0004] However, during the use of the existing PCB grinding machine, due to the different thicknesses of the PCB boards and the grinding consumables of the grinding machine, there will be wear and tear after grinding multiple boards. Since the grinding plate assembly cannot adjust the height and the force exerted by contacting the PCB board according to needs, there are certain differences in the grinding plates produced by the PCB boards, which affects the grinding effect. For this reason, we propose a PCB grinding machine. Utility Model Content
