The vibration gear 347 is coaxially mounted on the rotating shaft of the vibration roller 346, and the vibration rack 348 is fixedly mounted on the top wall of the end of the connecting plate 342 in the vertical direction, and the vibration rack 348 is located on the side of the top plate 343 away from the bracket 334, and the vibration rack 348 is meshed with the vibration gear 347. A baffle is also fixedly mounted on the upper end of the vibration rack 348, and the baffle extends to the upper end of the top plate 343 in a direction parallel to the axis of the connecting plate 342, and a guide groove for horizontal sliding of the top plate 343 is also provided on the bottom wall of the baffle.

[0051] Reference Figure 7 and Figure 8 Two vibration springs 349 are provided, and the two vibration springs 349 correspond to the connecting plate 342 and the baffle plate respectively, and one of the vibration springs 349 is installed in the buffer groove 3421, and the vibration spring 349 is located on the side of the top plate 343 away from the vibration rack 348, and one end of the vibration spring 349 conflicts with the inner wall of the buffer groove 3421, and the other end conflicts with the side wall of the top plate 343, and the other vibration spring 349 is installed in the guide groove, and one end of the vibration spring 349 conflicts with the side wall of the guide groove, and the other end conflicts with the side wall of the top plate 343 away from the vibration rack 348. A reciprocating groove for the horizontal sliding of the rotating shaft of the collection box 341 is also provided on the side wall of the conveying frame 31.

[0052] Reference Figure 2 and Figure 8 , the PCB board is transported to the conveying mechanism 3 through the conveying component 24, and the bracket 334 is driven to move downward by the adhesion cylinder 333, thereby driving the adhesion roller 331 to move downward to the side wall of the conveying roller 321, so that the adhesion motor 332 drives the adhesion roller 331 to rotate clockwise, so that the adhesion roller 331 drives the conveying roller 321 to rotate counterclockwise through friction, so that the conveying roller 321 rolls over the PCB board and pushes the PCB board to the direction of the next process, so that when the conveying roller 321 rolls over the PCB board, the dust on the PCB board can be adhered to the side wall of the conveying roller 321, and in the process of the adhesion roller 331 driving the conveying roller 321 to rotate through friction, the dust is adhered to the adhesion roller 331.

[0053] Reference Figure 8 and Fig. 9, while the bracket 334 moves downward, the bracket 334 drives the top plate 343 to move downward through the connecting plate 342, so that the top plate 343 moves downward relative to the eccentric column 345 on the deflection plate 344, so that the eccentric column 345 slides along the horizontal section 3431 of the control slot on the top plate 343 to the vertical section 3432, so that the deflection plate 344 rotates and drives the collection box 341 to rotate clockwise until the opening of the collection box 341 faces upward. At the same time, the connecting plate 342 drives the vibration rack 348 to move downward, so that the vibration rack 348 drives the vibration gear 347 to rotate counterclockwise, so that the vibration gear 347 drives the vibration roller 346 to rotate, thereby rotating through the protrusion 3461 on the vibration roller 346. When the collection box 341 rotates to a vertical state and the eccentric column 345 slides, When it moves to the vertical section 3432 of the control groove, the rotating middle protrusion 3461 begins to continuously resist the collection box 341 and pushes the collection box 341 in the direction away from the vibration roller 346, so that the collection box 341 drives the deflection plate 344 to move horizontally through the rotating shaft, so that the deflection plate 344 drives the top plate 343 to move away from the vibration roller 346 through the eccentric column 345 and compresses the vibration spring 349, and when the protrusion 3461 on the vibration roller 346 separates from the collection box 341, the vibration spring 349 drives the top plate 343 to reset, thereby driving the deflection plate 344 and the collection box 341 to reset, so that the collection box 341 vibrates, thereby vibrating the waste impurities on the scraper 3411 at the opening of the collection box 341 to fall into the collection box 341, thereby collecting the waste impurities.

[0054] Reference Figure 8 and Fig. 9 When the PCB board is conveyed, the bracket 334 is driven to move upward by the adhesion cylinder 333, thereby driving the adhesion roller 331 and the connecting plate 342 to move upward, so that the adhesion roller 331 is separated from the conveying roller 321, and the connecting plate 342 drives the top plate 343 and the vibration rack 348 to move upward, so that the eccentric column 345 slides along the vertical section 3432 of the control groove to the horizontal section 3431, and slides in the horizontal section 3431, so that the deflection plate 344 rotates counterclockwise, thereby driving the collection box 341 to rotate in the direction of the adhesion roller 331. At the same time, the vibration rack 348 moves upward with the upward movement of the connecting plate 342, thereby driving the vibration gear 347 to rotate clockwise, thereby driving the vibration roller 346 to rotate clockwise.

[0055] Reference Figure 8 and Fig. 9When the connecting plate 342 drives the top plate 343 to move upward to make the eccentric column 345 move to the horizontal section 3431 of the control groove, the vibration roller 346 just drives the protrusion 3461 to separate from the collection box 341, and then as the connecting plate 342 continues to move upward, the eccentric column 345 slides in the horizontal section 3431 of the control groove, causing the collection box 341 to rotate away from the vibration roller 346, so that the collection box 341 is separated from the protrusion 3461 on the vibration roller 346, so that the collection box 341 no longer vibrates. When the connecting plate 342 rises to the highest position, the adhesion roller 331 also rises to the highest position, and at this time, the side wall of the adhesion roller 331 conflicts with the scraper 3411 at the opening position of the collection box 341. As the adhesion motor 332 drives the adhesion roller 331 to rotate counterclockwise, the scraper 3411 slides along the peripheral side wall of the adhesion roller 331 , thereby scraping the dust adhered to the adhesion roller 331 into the collection box 341 , thereby cleaning the adhesion roller 331 .

[0056] The working principle of the embodiment of the present application is as follows: by conveying batches of PCB boards to the pushing mechanism 2 and stacking them on the carrying plate 211, then limiting the PCB board above the PCB board on the carrying plate 211 by the limiting component 22, and then pushing the PCB board on the carrying plate 211 to the supporting member by the separating component 23, and then driving the first supporting plate 235 and the second supporting plate 236 to descend respectively by the first supporting cylinder 237 and the second supporting cylinder 238, thereby driving the PCB board to fall onto the conveyor belt 242, and then conveying the PCB board to the conveying mechanism 3 by the conveying component 24, and then releasing the PCB board by the limiting component 22, so that the stacked PCB boards fall on the carrying plate 211, and then conveying the stacked PCB boards to the conveying mechanism 3 one by one according to the above steps.

[0057] When the PCB board is conveyed to the conveying mechanism 3, the PCB board is conveyed to the next process through the conveying component 32, and the dust on the PCB board is adhered to the conveying component 32 through the conveying component 32 and transferred to the adhesive component 33 with greater viscosity. Finally, the dust adhered to the adhesive roller 331 on the adhesive component 33 is cleaned by the cleaning component 34, so as to maintain the friction between the adhesive roller 331 and the conveying roller 321, thereby facilitating the driving of the conveying roller 321 to rotate, so as to continuously convey the PCB board and continuously adhere the dust on the PCB board.

[0058] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
