TECHNICAL FIELD

[0001] The utility model relates to the technical field of rough grinding equipment, especially to a raw material plate rough grinding equipment for circuit board copper plating. BACKGROUND

[0002] The circuit board can be called a printed wiring board or a printed circuit board. The raw material plate of the circuit board needs to be copper plated in the processing process. The purpose of copper plating is to add a layer of 0.3um-0.5um copper in the hole by using the principle of chemical reaction, so that the originally non-conductive hole has conductivity, to facilitate the smooth progress of the subsequent panel plating and pattern plating. The raw material plate needs to be rough ground before copper plating. The raw material plate is usually rough ground by using a rough grinding device.

[0003] The raw material plate needs to be continuously moved to rough grind the end face of the raw material plate during rough grinding by the rough grinding device, because the raw material plate has a certain width. However, the existing rough grinding device is not convenient for moving and adjusting the width direction of the raw material plate, and rough grinding is very inconvenient. SUMMARY

[0004] Therefore, the purpose of the utility model is to provide a raw material plate rough grinding device for circuit board copper plating to solve the problems mentioned in the background art and overcome the deficiencies in the prior art.

[0005] In order to achieve the above-mentioned purpose, one embodiment of the utility model provides a raw material plate rough grinding device for circuit board copper plating, which comprises a rough grinding support, a rough grinding wheel is fixedly installed at the top end of the rough grinding support, a lifting rough grinding table is arranged below the rough grinding wheel, a conveyor belt wheel set is fixedly installed at the top end of the lifting rough grinding table, a clamping piece is arranged above the conveyor belt wheel set, a telescopic support is fixedly installed at one end of the clamping piece, a laser distance measuring sensor is fixedly installed in the telescopic support, a dust suction head is fixedly installed at the top end of the telescopic support, a dust collection cavity is fixedly installed in the dust suction head through a conveying hose, and a negative pressure fan is fixedly installed at one end of the dust collection cavity.
