[0082] In the embodiment, the conveying device 2 comprises a conveying motor and a roller assembly, the conveying motor drives the roller assembly to rotate, and the roller assembly can convey the tray 200 along the X-axis direction. In some other embodiments, the conveying device 2 is a belt pulley device.

[0083] Optionally, the lower tray machine 10 further comprises a dust collection unit 6, the dust collection unit 6 comprising a dust collection main machine 61, a first dust collection cover 62, a fan 63 and a second dust collection cover 64, the dust collection main machine 61 being arranged at one side of the first support 1; the first dust collection cover 62 is arranged at the right position of the tearing rubber position, both ends of the first dust collection cover 62 along the Y-axis direction are provided with tearing rubber openings 621, the bottom of the first dust collection cover 62 is connected with a first ventilation pipe, the first ventilation pipe is connected with the dust collection inlet of the dust collection main machine 61; the fan 63 is arranged at the top of the first dust collection cover 62, the fan 63 blows air from the top to the tray 200 located at the tearing rubber position; the second dust collection cover 64 is arranged at the cleaning position, the polishing device 3 is located inside the second dust collection cover 64, the bottom of the second dust collection cover 64 is connected with a second ventilation pipe, the second ventilation pipe is connected with the dust collection inlet of the dust collection main machine 61.

[0084] The first ventilation pipe and the second ventilation pipe of the embodiment are both flexible pipes, and the specific structure is not shown.

[0085] Specifically, the employee tears the rubber of the tray 200 at the tearing rubber opening 621, so that the tearing rubber opening 621 is arranged at both ends of the first dust collection cover 62 along the Y-axis direction, which facilitates the employees originally located at the wiping position to support the tearing rubber work and improves the tearing rubber efficiency; the first dust collection cover 62 is arranged at the tearing rubber position, when tearing the rubber, the fan 63 operates, the impurities on the tray 200 and the rubber just torn by the employee are blown into the first ventilation pipe, which are collected by the dust collection main machine 61, the first dust collection cover 62 can avoid the impurities in the tearing rubber position from drifting to other positions to cause pollution, and can also avoid the impurities from the outside from drifting to the tearing rubber position; the second dust collection cover 64 is arranged at the periphery of the polishing device 3, when the polishing device 3 polishes the tray 200, the impurities adhered to the tray 200 are raised, the second dust collection cover 64 can avoid the impurities from drifting to other positions to cause pollution, and the impurities in the cleaning position are transported to the dust collection main machine 61 through the second ventilation pipe.

[0086] Optionally, the polishing device 3 comprises a polishing motor 31 and a polishing roller 32, the end of the polishing roller 32 is provided with a transmission wheel 33, a transmission belt is wound between the output end of the polishing motor 31 and the transmission wheel 33, the polishing motor 31 drives the polishing roller 32 to rotate to polish the tray 200 located at the cleaning position. The conveying device 2 drives the tray 200 to pass below the polishing roller 32, and the polishing roller 32 polishes and cleans the moving tray 200. Optionally, the polishing roller 32 is a roller provided with a brush.

[0087] Optionally, the polishing roller 32 is provided as two, the two polishing rollers 32 are arranged at intervals along the X-axis direction, the polishing motor 31 is located between the two polishing rollers 32, and the polishing motor 31 simultaneously drives the two polishing rollers 32 to rotate in opposite directions.

[0088] Specifically, one polishing motor 31 is used to drive two polishing rollers 32, which reduces the cost; the two polishing rollers 32 rotate in opposite directions, and the tray 200 first passes through one polishing roller 32 and then passes through the other polishing roller 32, which can improve the cleaning efficiency of the tray 200. For example, impurities adhere to one right-angle position of the tray 200, which is located in the direction away from the conveying direction of the conveying device 2, i.e., the right-angle position is located in the opposite direction of the X-axis. At this time, the polishing roller 32 rotating clockwise can contact this position. When some other impurities adhere to another right-angle position of the tray 200, which is located in the direction of the X-axis, at this time, the polishing roller 32 rotating counterclockwise can contact this position. The embodiment sets two polishing rollers 32 rotating in opposite directions, which can improve the polishing and cleaning efficiency and ensure the polishing and cleaning effect.

[0089] Optionally, the polishing device 3 further comprises a support plate 34, a bearing plate 35, a locking rod 36, and a spring 37. The support plate 34 is fixedly installed on the first support 1. The bearing plate 35 is movably installed on the support plate 34 along the Z-axis direction. The end of the polishing roller 32 is installed on the bearing plate 35 through a first bearing. The locking rod 36 is threadedly connected to the support plate 34 and located above the bearing plate 35. The spring 37 is arranged between the bearing plate 35 and the locking rod 36. One end of the spring 37 is in abutment or connected with the bearing plate 35, and the other end of the spring 37 is in abutment or connected with the locking rod 36.

[0090] When the tray 200 passes through the bottom of the polishing roller 32, the polishing roller 32 is pushed upward by the tray 200, which can avoid the polishing roller 32 blocking the movement of the tray 200 along the X-axis direction. When the polishing roller 32 moves upward, the bearing plate 35 moves upward along the Z-axis direction, and the spring 37 is compressed. When the tray 200 completely passes through the bottom of the polishing roller 32, the spring 37 drives the bearing plate 35 and the polishing roller 32 to move downward. When another specification of tray 200 needs to be cleaned, for example, the thickness of the tray 200 of this specification is thicker. At this time, the locking rod 36 is rotated to make the locking rod 36 rise, which increases the compression distance of the spring 37, so that the tray 200 of this specification can pass through the bottom of the polishing roller 32.

[0091] Optionally, the turnover device 4 comprises a turnover motor 41 and a clamping assembly 42. The turnover motor 41 is arranged on one side of the wiping station.

The clamping assembly 42 is used for clamping the tray 200, and the turnover motor 41 is used for driving the clamping assembly 42 and the tray 200 to rotate.

[0092] Specifically, the two clamping assemblies 42 clamp the tray 200 from both ends to ensure the stability of the tray 200 and avoid loosening of the tray 200 during wiping.

[0093] Optionally, the clamping assembly 42 comprises a bearing table 421, a short-side air cylinder 422, and a bidirectional air cylinder 424. The bearing table 421 is connected to the output end of the turnover motor 41 and is used to bear the tray 200. The short-side air cylinder 422 is installed on the bearing table 421, and the output end of the short-side air cylinder 422 is provided with a short-side clamping plate 423.

The driving direction of the bidirectional air cylinder 424 is perpendicular to the driving direction of the short-side air cylinder 422. The bidirectional air cylinder 424 drives the two long-side clamping plates 425 to move close to each other to clamp the long side of the tray 200.

[0094] Specifically, the direction of the wiping force applied by the staff to the tray 200 is not fixed, so it is necessary to improve the clamping stability of the tray 200 to avoid loosening of the tray 200. When the tray 200 moves to the wiping station, the staff lifts the tray 200 and places it on the bearing table 421. The bidirectional air cylinder 424 drives the long-side clamping plates 425 to clamp the long side of the tray 200, and the short-side air cylinder 422 drives the short-side clamping plate 423 to clamp the short side of the tray 200, so as to ensure the clamping stability.

The stop block 429 is installed on the bearing table 421 and protrudes towards one side of the bearing seat 426. The stop block 429 rotates with the bearing table 421, and the stop block 429 is used to abut against the stop bolt 428 to limit the rotation of the bearing table 421.

[0096] Optionally, the bearing shaft is connected to the output end of the turnover motor 41 through a shaft coupling.

[0097] Specifically, in order to avoid the conveying device 2 blocking the overturning of the tray 200, the embodiment sets a boss 427 protruding along the Z-axis direction on the top of the bearing seat 426, which improves the horizontal height of the bearing table 421. When the tray 200 overturns with the bearing table 421, the tray 200 will not touch the bottom conveying device 2, avoiding rigid collision; the embodiment sets a stop bolt 428 on both sides of the boss 427, limiting the overturning angle of the bearing table 421 to 180°, ensuring that the wiping work can be carried out smoothly.

[0098] Optionally, the lower tray device 5 further comprises a locking mechanism 53, which is arranged at the bottom of the second support 51. The locking mechanism 53 comprises a support table 531, a buffer 532, a locking cylinder 533, and a locking block 534. The support table 531 is fixedly connected to the second support 51. The buffer 532 is arranged above the support table 531. The body end of the locking cylinder 533 is rotationally connected to the support table 531.

The bottom connecting end of the locking block 534 is rotationally connected to the support table 531. The locking cylinder 533 drives the locking block 534 to rotate around the X-axis, so that the top locking end of the locking block 534 avoids or locks the material cart 300.

[0099] Specifically, after the material cart 300 is pushed into the lower tray station, it is locked by the locking mechanism 53, avoiding the shaking of the material cart 300, which causes the carrying mechanism 52 to fail to accurately place the tray 200 on the material cart 300. When the material cart 300 enters the lower tray station, the locking cylinder 533 first drives the locking block 534 to rotate forward, so that the horizontal height of the top locking end of the locking block 534 is lower than that of the bottom frame of the material cart 300, and the top locking end of the locking block 534 avoids the material cart 300. After the material cart 300 enters the lower tray station, the bottom frame of the material cart 300 completely passes over the top locking end of the locking block 534. The locking cylinder 533 then drives the locking block 534 to rotate backward, so that the top locking end of the locking block 534 abuts against the bottom frame of the material cart 300.
