The chips 8 are placed on the photovoltaic circuit board bodies 10 through a plurality of silicone suction heads 23 for chip mounting processing. This technology is the prior art and will not be elaborated here, thus completing the automatic feeding operation.

[0021] Above the conveying mechanism on the right side, there is a dust removal mechanism. The dust removal mechanism includes a reciprocating screw rod 12 rotatably connected to a pair of L-shaped rods 16 on the right side. A brush plate 14 is sleeved on the outer wall of the reciprocating screw rod 12. A sliding rod 13 is fixedly connected to the pair of L-shaped rods 16 on the right side. The sliding rod 13 penetrates through the brush plate 14 and is slidably connected to it. A belt 11 is sleeved on the outer walls of the rotating rod 3 and the reciprocating screw rod 12. A driving wheel is fixedly connected to the outer wall of the rotating rod 3, and a driven wheel is fixedly connected to the outer wall of the reciprocating screw rod 12. The belt 11 is sleeved on the outer walls of the driving wheel and the driven wheel. There are multiple soft hair brushes at the bottom of the brush plate 14. Through the forward and backward movement of the soft hair brushes provided, cleaning is carried out to remove the dust adhering to the top of the chip 8, ensuring the stability of subsequent adsorption.

[0022] Four L-shaped rods 16 are fixedly connected to the top of the base 1. The four L-shaped rods 16 are fixedly connected to a top plate 15. A moving motor 17 is fixedly connected to the side wall of the top plate 15. The output end of the moving motor 17 is fixedly connected to a threaded rod 18. The threaded rod 18 penetrates through the top plate 15 and is rotatably connected to it. A slider 19 threadedly connected to the threaded rod 18 is sleeved on the outer wall of the threaded rod 18. The slider 19 is slidably connected to the top plate 15. A sliding opening is formed in the top plate 15. The slider 19 is located in the sliding opening and is slidably connected to its inner wall.

The hydraulic rod 20 is started to drive the lifting plate 21 and the adsorbed chip 8 to move downward until the chip 8 moves onto the photovoltaic circuit board body 10 and contacts it. At this time, the vacuum generator 22 stops, and the silica gel suction head 23 returns to atmospheric pressure and no longer adsorbs the chip 8, completing the automatic feeding operation of the chip 8 and the photovoltaic circuit board body 10; when the conveyor belt 5 and the chip 8 are being conveyed, the rotating rod 3 rotates to drive the driving wheel, the belt 11, the driven wheel, and the reciprocating lead screw 12 to rotate, so that the brush plate 14 moves back and forth on the sliding rod 13. The soft hair brush provided at the bottom of the brush plate 14 moves to clean the upper surface of the conveyed chip 8, removing the adhered dust and ensuring good subsequent adsorption effect.
