Grinding device and grinding method for circuit board pretreatment

Abstract

The invention relates to the field of circuit board production, and discloses a grinding device for pretreatment of circuit boards and a grinding method thereof, including a machine base, on which a machine platform is arranged, on which a circuit board is placed The two ends of the machine table are rotatably installed with transmission rollers, the base is equipped with an operator, the top of the machine table is provided with a rotating device box, and the top of the rotating device box is connected with an upper rotating motor. The inside of the rotating device box is provided with an autorotation drive box. The invention divides and plants the traditional brush head on the brush rod and abandons the traditional integral brush head structure, so that the brush head can be driven by the upper rotating motor to realize the traditional overall "autorotation" grinding function, and at the same time, it can be driven by rotation forever The drive of the magnet and the rotation driving magnet above the brush head promotes the rotation of the brush head, so that the brush head performs self-rotation grinding during the integral grinding process, which effectively improves the grinding efficiency.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a grinding device and a grinding method for circuit board pretreatment. Background technique [0002] In the 21st century, human beings have entered a highly information-based society. In the information industry, printed circuit boards (PCBs) are an indispensable and important pillar product. Informatization has prompted a technological revolution and changes in the industrial structure in the electronics industry, and at the same time brought new challenges to the printed circuit board manufacturing industry. Following the trend of technological revolution, PCB products are also developing in the direction of high density, miniaturization and light weight. Among them, high density refers to increasing the device loading and wiring density per unit area of ​​the PCB. The methods adopted are circuit refinement, micro-aperture and multi-layer. This puts forward t...
