8. The grinding method of the grinding device for the pretreatment of the circuit board is characterized by comprising the following steps of: the grinding method comprises the following steps:
s1: when the circuit board is required to be ground, the circuit board is conveyed to the conveying rollers (8) through the conveying belt (21) on the conveying seat (2), then the pressing block (82) is driven by the electric telescopic rod (81) to press down and fix the circuit board on the conveying rollers (8), so that the grinding effect of the circuit board is not influenced by loosening when the grinding equipment (3) grinds the circuit board, the conveying rollers (8) are used for supporting the circuit board, and scraps generated when the grinding equipment (3) grinds the circuit board can fall through gaps between the conveying rollers (8), so that residues after grinding are located on the conveying rollers (8) and influence on the subsequent circuit board is avoided;
s2: when the circuit board is limited on the conveying roller (8), the driving motor (32) drives the rotating rod (33) to rotate, the rotating rod (33) rotates to drive the grinding roller (34) to rotate, and the grinding roller (34) grinds the surface of the circuit board on the conveying roller (8), so that the surface of the circuit board is smoother and convenient for the subsequent use of the circuit board;
s3: when a driving motor (32) drives a rotating rod (33) to grind the surface of a circuit board, the rotating rod (33) drives a driving disc (4) to rotate, a side bar (41) arranged on the driving disc (4) is in contact with a collision rod (54) in a rotating way, the collision rod (54) drives a movable frame (52) to transversely move, the movable frame (52) moves to enable the movable rod (51) to slide on a bearing table (31), a transfer rod (6) arranged on the movable rod (51) drives a rotating shaft (61) to rotate, fan blades (62) arranged on the rotating shaft (61) face the circuit board on the grinding roller (34) and a conveying roller (8), and when the grinding roller (34) grinds the circuit board, waste generated in the grinding process of the circuit board can be blown off through the fan blades (62), and the waste generated in the grinding process of the circuit board is prevented from being remained on the surface of the grinding roller (34) and the circuit board to affect the subsequent circuit board and the subsequent circuit board is convenient to process the circuit board;
s4: when the grinding roller (34) grinds the surface of the circuit board, a part of waste scraps can fall onto the conveying roller (8), in order to avoid the influence of the waste scraps on the circuit board which is conveyed subsequently, the supporting frame (71) can enable the cleaning roller (72) to collide with the surface of the grinding roller (34) under the pressure of the collision spring (73), and then the cleaning roller (72) can wipe the surface of the conveying roller (8) while the moving frame (52) moves, so that the surface of the conveying roller (8) is cleaned, and the influence of the scraps generated after grinding on the subsequent circuit board is avoided;
s5: when the cleaning roller (72) moves and cleans the surface of the conveying roller (8), the cleaning roller (72) is contacted with the wedge-shaped inclined block (9) in the moving process, and a plurality of bulges arranged on the wedge-shaped inclined block (9) can shake the cleaning roller (72), so that scraps on the cleaning roller (72) are removed in a shaking mode, and the self-cleaning effect of the cleaning roller (72) is achieved.
