[0002] In the processing of circuit boards, electroplating wires of corresponding thickness are often used to weld various nodes therein. In order to make the electroplating wires adapt to the welding points, people usually set a grinding device for the thickness of the electroplating wires of the circuit board on one side of the circuit board to grind the unsuitable electroplating wires, thereby ensuring that the size of the electroplating wires can be fully adapted to the connection nodes of the circuit board.

[0003] An existing grinding device for the roughness of the electroplating line of a circuit board usually uses a rotating motor to drive a grinding fixed rod to rotate through a gear set structure, so that a grinding device on the side of the grinding fixed rod grinds the electroplating line.

[0004] This type of grinding device usually uses the rotation of a friction belt structure to grind the electroplating wire, but the commonly used friction belt is relatively thin and is in a tight state with the electroplating wire during grinding, which makes it very easy to break during the continuous rotation and grinding, resulting in the electroplating wire being damaged.

[0020] As the instruction manual Figure 1 , 2 As shown in FIG. 3 , an elastic grinding device 5 is provided between the grinding fixing rod 2 and located on both sides of the electroplating line. The elastic grinding device 5 includes a convex column 51, a spring 52 supporting the rebound of the convex column 51, and a stepped column hole 53 located outside the convex column 51. The convex column 51 and the spring 52 pass through the coarse column hole of the stepped column hole 53 in sequence. A sealing plate 54 is provided at the coarse end of the stepped column hole 53. The sealing plate 54 is connected to the bottom surface of the stepped column hole 53 through a bolt structure. The open structure of the stepped column hole 53 makes it easier to replace the spring 52 and the convex column 51.
