[0037] By designing the slide plate 12, the fixed plate 13, the first connecting plate 14 and the first spring 16, the movable frame 8 is elastically connected to the first movable block 10 in the horizontal direction. When the rotating scraper assembly drives the first movable block 10, the slide plate 12 and the movable frame 8 to rotate synchronously, the movable frame 8 drives the ball 21 to roll on the surface of the first curved plate 17 through the support plate 19. When it is necessary to drive the slide plate 12, the movable frame 8 and the cleaning plate 9 to move axially relative to the driven roller 3, the first curved plate 17 is driven to move by the first hydraulic telescopic rod 18. The first curved plate 17 pushes the ball 21, the support plate 19, the movable frame 8 and the slide plate 12 to slide relative to the fixed plate 13.

As the conveyor belt 4 continues to move, the cleaning plate 9 rotates around the driven roller 3, and the cleaning plate 9 can clean the surface of the conveyor belt 4. When the adhesion force of impurities on the conveyor belt 4 is strong, the impurities move synchronously with the conveyor belt 4, and the impurities push the cleaning plate 9, the first supporting portion 26, the guide column 27 and the fixed plate 29 to slide relative to the second supporting portion 28 and the second movable block 23. The third spring 30 is in a compressed state. When the distance between the cleaning plate 9 and the conveyor belt 4 is greater than the diameter of the impurities, the impurities can slide from one side of the cleaning plate 9. When the adhesion force of the impurities is strong, the cleaning plate 9 can slide relative to the second movable block 23, thereby protecting the cleaning plate 9.

[0039] The movable column 35 contacts the inner side of the second curved plate 31. When the conveyor belt 4 needs to be cleaned, the tooth plate 51 is driven to move by the second hydraulic telescopic rod 50. The tooth plate 51 drives the rotating shaft 48 to rotate through the gear 49. The rotating shaft 48 can drive the rotating frame 11, the second slider 42 and the first movable block 10 to rotate. The movable column 35 slides on the second curved plate 31. When the movable column 35 slides from the inner side of the second curved plate 31 to the side of the first slider 33 away from the second curved plate 31 through the inclined surface of the first support plate 33, the first support plate 33 supports the movable column 35 and the first movable block 10 to slide relative to the second slider 42. The fourth spring 44 is in a stretched state, and the first movable block 10 can drive the movable frame 8 and the cleaning The plate 9 moves toward the conveyor belt 4, reducing the distance between the movable frame 8 and the conveyor belt 4, so that the elastic support can apply elastic force to the cleaning plate 9 to make the cleaning plate 9 close to the conveyor belt 4. When the rotating frame 11 rotates to the preset position, the end of one of the support columns 36 on the movable column 35 slides to the inclined surface of one of the second support plates 41. As the rotating frame 11 continues to rotate, the second support plate 41 supports the support column 36 and the movable column 35 to slide relative to the first movable block 10. The iron block 39 is no longer magnetically attracted to the magnet block 40, and the movable column 35 slides relative to the first support plate 33.

As the rotating frame 11 continues to rotate, when the first support plate 33 is no longer located on one side of the movable column 35, a corresponding supporting column 36 on the movable column 35 contacts the inclined surface on the other second support plate 41, and the second support plate 41 pushes the movable column 35 and the supporting column 36 to slide in the opposite direction, the iron block 39 is magnetically attracted to the magnet block 40 again, the movable column 35 is fixed relative to the first movable block 10, and the end of the movable column 35 moves to the inner side of the second arc plate 31 again, and the movable column 35 is reset to the initial position relative to the first movable block 10.When the rotating frame 11 drives the first movable block 10 and the movable column 35 to rotate around the driven roller 3, the movable column 35 can slide from the inner wall of the second arc plate 31 to the first support plate 33 again, and the etcher 53 can be driven by the third hydraulic telescopic rod 54 to move axially relative to the driving roller 2 and the driven roller 3, so as to change the position of the etcher 53, and ensure that the etcher 53 processes different positions on the circuit board. When the impurities on the conveyor belt 4 rotate from the top of the driving roller 2 to the bottom of the driving roller 2, the impurities not adsorbed on the surface of the conveyor belt 4 are collected by the collection box 55 located below the driving roller 2, and the impurities cleaned by the cleaning plate 9 are collected by the collection box 55 located below the driven roller 3. The staff drives the collection box 55 to move up to disengage the plug plate 58 from the slot 57, and the support frame 56 no longer supports and limits the collection box 55, so that the collection box 55 can be removed.

[0041] By designing the slide plate 12, the fixed plate 13, the first connecting plate 14 and the first spring 16, the movable frame 8 is elastically connected to the first movable block 10 in the horizontal direction. When the rotating scraper assembly drives the first movable block 10, the slide plate 12 and the movable frame 8 to rotate synchronously, the movable frame 8 drives the ball 21 to roll on the surface of the first curved plate 17 through the support plate 19. When it is necessary to drive the slide plate 12, the movable frame 8 and the cleaning plate 9 to move axially relative to the driven roller 3, the first curved plate 17 is driven to move by the first hydraulic telescopic rod 18. The first curved plate 17 pushes the ball 21, the support plate 19, the movable frame 8 and the slide plate 12 to slide relative to the fixed plate 13. The first spring 16 is deformed to change the position of the cleaning plate 9. When the first hydraulic telescopic rod 18 drives the first curved plate 17 to move in the opposite direction, the first spring 16 can drive the slide plate 12 and the movable frame 8 to return to the initial position relative to the fixed plate 13. By designing the support plate 19, the first accommodating groove 20 and the ball 21, the relative movement of the movable frame 8 is reduced. For the resistance encountered when the first arc-shaped plate 17 moves, when the rotating scraper assembly drives the first movable block 10, the slide plate 12 and the movable frame 8 to rotate synchronously, when the cleaning plate 9 is needed to clean the conveyor belt 4, the second spring 25 is in a compressed state, and the second spring 25 applies pressure to the second movable block 23 to make the cleaning plate 9 close to the conveyor belt 4. As the conveyor belt 4 continues to move, the cleaning plate 9 rotates around the driven roller 3, and the cleaning plate 9 can clean the surface of the conveyor belt 4. When the adhesion force of impurities on the conveyor belt 4 is strong, the impurities move synchronously with the conveyor belt 4, and the impurities push the cleaning plate 9, the first supporting portion 26, the guide column 27 and the fixed plate 29 to slide relative to the second supporting portion 28 and the second movable block 23. The third spring 30 is in a compressed state. When the distance between the cleaning plate 9 and the conveyor belt 4 is greater than the diameter of the impurities, the impurities can slide from one side of the cleaning plate 9. When the adhesion force of the impurities is strong, the cleaning plate 9 can slide relative to the second movable block 23, thereby protecting the cleaning plate 9;

[0042] The movable column 35 contacts the inner side of the second curved plate 31. When the conveyor belt 4 needs to be cleaned, the tooth plate 51 is driven to move by the second hydraulic telescopic rod 50. The tooth plate 51 drives the rotating shaft 48 to rotate through the gear 49. The rotating shaft 48 can drive the rotating frame 11, the second slider 42 and the first movable block 10 to rotate. The rotating frame 11 drives the roller 47 to move on the inner wall of the control shell 6. The design of the roller 47 increases the stability of the rotating frame 11 during rotation. The movable column 35 slides on the second curved plate 31. When the movable column 35 slides from the inner side of the second curved plate 31 to the side of the first bracket 33 away from the second curved plate 31 through the inclined surface of the first support plate 33, the first bracket 33 supports the movable column 35 and the first movable block 10 relative to the second slider 4. 2 slides, the fourth spring 44 is in a stretched state, and the first movable block 10 can drive the movable frame 8 and the cleaning plate 9 to move toward the conveyor belt 4 through the horizontal adjustment structure, reducing the distance between the movable frame 8 and the conveyor belt 4, so that the elastic supporter can apply elastic force to the cleaning plate 9, so that the cleaning plate 9 is in close contact with the conveyor belt 4. When the rotating frame 11 rotates to the preset position, the end of one of the support columns 36 on the movable column 35 slides to the inclined surface of one of the second support plates 41. As the rotating frame 11 continues to rotate, the second support plate 41 supports the support column 36 and the movable column 35 to slide relative to the first movable block 10, the iron block 39 is no longer magnetically attracted to the magnet block 40, and the movable column 35 slides relative to the first support plate 33, and finally one of the support columns 36 slides into the corresponding The movable column 35 is no longer in contact with the side of the first support plate 33 away from the second arc plate 31, and the first support plate 33 no longer supports the movable column 35 and the first movable block 10. The fourth spring 44 drives the first movable block 10 to slide to the initial position relative to the second slider 42, and at this time, the guide block 46 abuts against the side of the movable column 35 and the inner wall of the second guide groove 45 to ensure that the first movable block 10 stops after sliding to the preset position relative to the rotating frame 11, thereby increasing the distance between the movable frame 8 and the conveyor belt 4, and ensuring that the elastic support is not sufficient to support the cleaning plate 9 to contact the conveyor belt 4. At this time, the second hydraulic telescopic rod 50 drives the tooth plate 51 to move in the opposite direction, that is, The rotating shaft 48 and the gear 49 can be made to rotate in the opposite direction, and the cleaning plate 9 and the movable frame 8 can rotate in the opposite direction around the driven roller 3 to the initial position. When the movable frame 8 and the cleaning plate 9 rotate in the opposite direction to the initial position, the cleaning plate 9 will not contact the conveyor belt 4, so as to prevent the cleaning plate 9 from pushing the impurities back to the top of the conveyor belt 4. With the continuous rotation of the rotating frame 11, when the first support plate 33 is no longer located on one side of the movable column 35, a corresponding supporting column 36 on the movable column 35 contacts the inclined surface on the other second support plate 41, and the second support plate 41 drives the movable column 35 and the supporting column 36 to slide in the opposite direction, the iron block 39 is magnetically attracted to the magnet block 40 again, the movable column 35 is fixed relative to the first movable block 10, and the end of the movable column 35 moves to the inner side of the second arc plate 31 again.The movable column 35 is reset to the initial position relative to the first movable block 10. When the rotating frame 11 drives the first movable block 10 and the movable column 35 to rotate around the driven roller 3, the movable column 35 can slide from the inner wall of the second arc plate 31 to the first support plate 33 again. The etcher 53 is driven to move axially relative to the driving roller 2 and the driven roller 3 by the third hydraulic telescopic rod 54, so that the position of the etcher 53 can be changed to ensure that the etcher 53 processes different positions on the circuit board. When the impurities on the conveyor belt 4 rotate from the top of the driving roller 2 to the bottom of the driving roller 2, the impurities not adsorbed on the surface of the conveyor belt 4 are collected by the collection box 55 located below the driving roller 2, and the impurities cleaned by the cleaning plate 9 are collected by the collection box 55 located below the driven roller 3. The staff drives the collection box 55 to move up to disengage the plug plate 58 from the slot 57. The support frame 56 no longer supports and limits the collection box 55, and the collection box 55 can be removed.
