[0054] 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. One vibration spring 349 is installed in the buffer groove 3421 and is located on the side of the top plate 343 away from the vibration rack 348. One end of the vibration spring 349 contacts the inner wall of the buffer groove 3421, and the other end contacts the side wall of the top plate 343. The other vibration spring 349 is installed in the guide groove, and one end of the vibration spring 349 contacts the side wall of the guide groove, and the other end contacts the side wall of the top plate 343 away from the vibration rack 348. A reciprocating groove is also provided on the side wall of the conveyor frame 31 for the horizontal sliding of the rotating shaft of the collection box 341.

[0055] Reference Figure 2 and Figure 8 The PCB board is conveyed to the conveying mechanism 3 through the conveying assembly 24, and the bracket 334 is driven downward by the adhesion cylinder 333, thereby driving the adhesion roller 331 to move downward until it contacts 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 toward 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.

[0056] Reference Figure 8 and Figure 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 groove on the top plate 343 into the vertical section 3432, so that the deflection plate 344 rotates and drives the collection box 341 to rotate clockwise to the state that the opening of the collection box 341 is 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, so that the protrusion 3461 on the vibration roller 346 rotates, when the collection box 341 rotates to the vertical state, and the eccentric column 345 slides into the vertical section 3432 of the control groove, the protrusion 3461 in rotation begins to continuously resist the collection box 341 and pushes the collection box 341 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 is separated 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, so that the waste and impurities on the scraper 3411 at the opening of the collection box 341 are vibrated to fall into the collection box 341, thereby collecting the waste and impurities.

[0057] With reference to Figure 8 and Figure 9 When the PCB board conveying is completed, the bracket 334 is driven to move upward by the adhesion cylinder 333, so that the adhesion roller 331 and the connecting plate 342 are driven 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 toward 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.

[0058] With reference to Figure 8 and Figure 9When the connecting plate 342 drives the top plate 343 upward until the eccentric post 345 moves to the horizontal section 3431 of the control groove, the vibrating roller 346 just drives the protrusion 3461 to separate from the collection box 341. Then, as the connecting plate 342 continues to move upward, the eccentric post 345 slides in the horizontal section 3431 of the control groove, causing the collection box 341 to rotate away from the vibrating roller 346, separating the collection box 341 from the protrusion 3461 on the vibrating roller 346, and the collection box 341 no longer vibrates. When the connecting plate 342 rises to its highest position, the adhesion roller 331 also rises to its highest position. At this time, the side wall of the adhesion roller 331 contacts the scraper 3411 at the opening 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 .

[0059] 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 carrier plate 211, then limiting the PCB boards above the PCB boards on the carrier plate 211 by the limiting component 22, and then pushing the PCB boards located on the carrier 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 boards to fall onto the conveyor belt 242, and then conveying the PCB boards to the conveying mechanism 3 by the conveying component 24, and then releasing the PCB boards by the limiting component 22, so that the stacked PCB boards fall on the carrier plate 211, and then conveying the stacked PCB boards one by one to the conveying mechanism 3 according to the above steps.

[0060] When the PCB board is conveyed to the conveying mechanism 3, the conveying component 32 conveys the PCB board to the next process, and the conveying component 32 adheres the dust on the PCB board to the conveying component 32 and transfers it to the adhesive component 33 with greater viscosity. Finally, the cleaning component 34 cleans the dust adhered to the adhesive roller 331 on the adhesive component 33, thereby maintaining 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.

[0061] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
