Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 The present invention provides an embodiment of a circuit board dust removal and anti-static treatment device, comprising a collection shell 1, with two top plates 2 fixedly connected to the top of the collection shell 1. The top plates 2 are used to support the upper structure of the entire device to make it more stable. The top of each of the two top plates 2 is fixedly connected to a top frame 5, which serves to support and fix the dust removal structure 6. The dust removal structure 6 is provided on the top frame 5.

[0026] Reference Figures 2-4 The dust removal structure 6 includes a motor B601, which is fixedly connected to the top of the top frame 5, providing power to the entire dust removal structure 6. The output shaft of the motor B601 is fixedly connected to a rotating rod B602, which transmits the motor's power downwards. The bottom end of the rotating rod B602 movably passes through the top of the top frame 5 and is fixedly connected to a crank 603. The crank 603 converts the rotational motion of the rotating rod B602 into reciprocating motion. A strip plate 604 is provided below the crank 603. A strip-shaped hole A605 is provided at the top. The surface of the crank pin of crank 603 is slidably connected to the inner wall of the strip-shaped hole A605. This sliding connection allows the strip plate 604 to move with the movement of crank 603. A limit post is fixedly connected to the bottom end of crank 603. The top surface of the limit post contacts the bottom surface of strip plate 604 to ensure the stability of the movement of strip plate 604. The top surface of strip plate 604 contacts the bottom surface of crank 603 to ensure good contact and force transmission between the two.

[0027] Reference Figures 2-4An electrostatic eliminator 606 is fixedly connected to the top of the strip plate 604 via two electric telescopic rods 6011. Both electric telescopic rods 6011 are fixedly connected to the top of the strip plate 604, and their ends sequentially pass through the top of the strip plate 604A and the slider 6010. This connection method allows the electrostatic eliminator 606 to be adjusted in position as needed. Two sliders 6010 are fixedly connected to the bottom of the strip plate 604. Block 6010 is used to guide the movement direction of strip plate 604. Limiting plate 607 is fixedly connected to the inner wall of top plate 2. A strip hole B609 is opened at the top of limiting plate 607. The bottom of strip plate 604 is slidably connected to the inner wall of strip hole B609 through slider 6010. This sliding connection method ensures the smoothness of movement of strip plate 604. Antistatic brush 608 is fixedly connected to the bottom of static eliminator 606. Antistatic brush 608 is used to directly contact circuit board to realize the functions of static elimination and dust removal.

[0028] Reference Figure 1 , Figure 2 A flipping structure 4 is provided on the inner side of the top plate 2. The flipping structure 4 includes a motor C, which is fixedly connected to the outer side of the top plate 2 to provide power to the flipping structure 4. The output shaft of the motor C is fixedly connected to a rotating rod A403. The end of the rotating rod A403 passes through the outer side of the top plate 2 and is rotatably connected to the inner side of the side plate. A turntable 401 is fixedly connected to the surface of the rotating rod A403. The edge of the turntable 401 is provided with a slot 402. The slot 402 is strip-shaped and has multiple sets. The multiple sets of slots 402 are equidistant from each other in a circle. The slot 402 is configured to cooperate with the top of the belt 9. This cooperation allows the turntable 401 to drive the circuit board on the belt 9 to perform a flipping operation.

[0029] A motor A3 is fixedly connected to the outer side of the top plate 2. A shaft 7 is fixedly connected to the output end of the motor A3. A transmission roller 8 is fixedly connected to the end of the shaft 7. Two belts 9 are respectively connected to the surface of the transmission roller 8. Four limiting rings 10 are fixedly connected to the surface of the transmission roller 8. The end face of the limiting ring 10 contacts the side of the belt 9. A collection groove is opened on the top of the collection shell 1. A cleaning brush 11 is fixedly connected to the inner side of the top plate 2. The top of the cleaning brush 11 contacts the surface of the belt 9.

[0030] Working Principle: When dust removal and anti-static treatment of circuit boards are required, motor A3 is first started. The output end of motor A3 drives shaft 7 to rotate, which in turn drives transmission roller 8 to rotate. Since two belts 9 are connected to the surface of transmission roller 8, and four limiting rings 10 are fixedly connected to the surface of transmission roller 8, with the end faces of the limiting rings 10 contacting the sides of the belts 9, the belts 9 can move smoothly under the drive of transmission roller 8. At this time, the circuit board to be processed is placed on the belts 9, and the movement of the belts 9 transports the circuit board into the device for processing. During the circuit board transport process, the cleaning brush 11 fixedly connected to the inner side of the top plate 2 contacts the surface of the belts 9, cleaning the surface of the belts 9 and preventing the accumulation of dust and other impurities from affecting the subsequent transport and processing of the circuit boards.

[0031] Simultaneously, the dust removal structure 6 on the top frame 5 begins to operate. Motor B601 is fixedly connected to the top of the top frame 5, and its output shaft drives the rotating rod B602 to rotate, causing the crank 603 at the bottom of the rotating rod B602 to rotate accordingly. The pin of crank 603 passes through the slotted hole A605 at the top of the strip plate 604 and slides against the inner wall of the slotted hole A605. At the same time, the top surface of the limiting post at the bottom of crank 603 contacts the bottom surface of the strip plate 604, and the bottom surface of crank 603 contacts the top surface of the strip plate 604. Under the rotation of crank 603, the strip plate 604 reciprocates along the direction of the slotted hole A605. Two sliders 6010 fixedly connected to the bottom of the strip plate 604 slide against the inner wall of the slotted hole B609 at the top of the limiting plate 607 on the inner wall of the top plate 2, ensuring the stability and directionality of the strip plate 604's movement.

[0032] During the reciprocating motion of the strip plate 604, the anti-static brush 608 fixedly connected to the bottom of the static eliminator 606 can perform static elimination treatment on the surface of the conveyed circuit board. At the same time, the anti-static brush 608 can also play a certain role in dust removal, sweeping off dust and other impurities from the surface of the circuit board. The swept-off dust and other impurities are collected through the collection groove opened at the top of the collection shell 1. In addition, a flipping structure 4 is also provided on the inner side of the top plate 2. The motor C is fixedly connected to the outer side of the top plate 2, and its output shaft drives the rotating rod A403 to rotate. The end of the rotating rod A403 passes through the outer side of the top plate 2 and is rotatably connected to the inner side of the side plate. A turntable 401 is fixedly connected to the surface of the rotating rod A403. Multiple sets of circumferentially equidistant strip-shaped slots 402 are opened on the edge of the turntable 401. The slots 402 are configured to cooperate with the top of the belt 9. When the circuit board needs to be flipped, motor C starts and turntable 401 rotates. Through the cooperation of slot 402 and the top of belt 9, the circuit board on belt 9 can be flipped over so that the other side of the circuit board faces up, so that the other side of the circuit board can be cleaned and treated with anti-static agents, thereby improving the comprehensiveness and effectiveness of the treatment.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
