[0002] Circuit boards can be called printed circuit boards or printed circuit boards, and are generally called flexible circuit boards. Flexible circuit boards are made of polyimide or polyester film as a substrate and are highly reliable and extremely flexible. They also have the characteristics of high wiring density, light weight, thin thickness, and good bending properties. During the production process of the circuit board, during the early processing, the side of the board needs to be polished to remove the burrs on the edge of the circuit board to facilitate later processing.

[0003] However, most of the current circuit board side grinding equipment fixes the circuit board, grinds one side of it, and then adjusts the position to grind the other side. This method wastes a lot of working time and is inconvenient for workers to operate. Moreover, most equipment can only grind one circuit board, and the grinding efficiency is low.

[0004] Therefore, a circuit board edge grinding device with multi-angle and multi-block grinding is proposed. Utility Model Content
