Description

Technical Field

[0001] The present invention relates to the technical field of spraying devices, and particularly relates to a spraying device for the production of flexible covers. Background Art

[0002] The spraying technology for flexible covers is a key surface treatment process in modern manufacturing, and is particularly applied in fields such as flexible electronics, display panels, and automotive parts. During the spraying process of flexible covers, due to reasons such as uneven atomization of the coating, improper spray gun angle, or excessive spraying pressure, some of the coating may splash or drip onto the surface of the platform where the flexible cover is placed, contaminating the placement platform.

[0003] Chinese Patent with Publication No. CN222490592U discloses a film laminating device for the production of flexible displays, including a positioning substrate, a positioning shell, a groove, a suction cup, and a vacuum pump. First, the vacuum pump connecting pipe can be connected to an external vacuum pump, and then the display screen can be placed inside the groove. After starting the vacuum pump, a negative pressure can be generated in the inner cavity of the positioning shell, so that the display screen can be adsorbed and positioned by a plurality of groups of suction cups, avoiding the situation of offset during the film laminating process. By setting a shell and leaving a diversion groove between the shell and the positioning shell, when film laminating and spraying the display screen, the film laminating coating dripping from the display screen will flow into the diversion groove and then be discharged from two diversion pipes. When the valve is in the open state, the film laminating coating will flow into the inside of the recovery box, thereby achieving the effect of collecting the excess film laminating coating and avoiding dripping around the device and affecting the environmental hygiene.

[0004] The above patent reduces the pollution of the film laminating material to the device by setting a diversion groove to collect the dripping film laminating coating into the recovery box. However, during actual use, there may also be coating residues on the adsorption table for placing the flexible cover, and some coatings are sticky. Even if the coating will flow along the diversion groove, residues will still form on the adsorption table. These accumulated residues may block the vacuum channels or adsorption grooves on the adsorption table, and even affect the flatness of the subsequent placement of the flexible cover on the adsorption table, resulting in uneven spraying of the coating on the flexible cover and affecting the production quality of the flexible cover.

[0005] Therefore, there is a need in the art for a spraying device for the production of flexible covers to solve the above problems. Summary of the Invention

[0006] The present invention provides a spraying device for the production of flexible covers, aiming to solve the problem that the spraying device in the related art cannot clean the spraying residues on the adsorption table, resulting in easy accumulation of the spraying residues, affecting the normal adsorption of the adsorption table on the flexible cover and the flatness of the flexible cover.

[0007] A spraying device for producing a flexible cover plate according to the present invention includes a box body, a spraying mechanism and a supporting mechanism arranged in the box body. The supporting mechanism includes a supporting box and an adsorption table rotatably connected to the supporting box. The adsorption table is used for adsorbing the flexible cover plate. A cleaning mechanism is arranged in the supporting box. A feeding area is arranged on the front side of the box body, and a discharging area is arranged on the rear side of the box body. A driving component is arranged in the box body to drive the supporting box to reciprocate between the feeding area and the discharging area. A driving structure is also arranged in the box body to drive the adsorption table to turn over. When the supporting box moves from the feeding area to the discharging area, the adsorption table is in a horizontal state. When the supporting box moves from the discharging area to the feeding area, the driving structure drives the adsorption table to turn over 180°, so that its adsorption surface faces downward, and the cleaning mechanism cleans the adsorption surface of the adsorption table.

[0008] The cleaning mechanism of the present invention can clean the adsorption surface while the supporting box returns to the feeding area. Cleaning the adsorption surface can remove residual paint, avoid the residual paint from contaminating the surface of the next flexible cover plate, resulting in defects or unevenness on the flexible cover plate, ensure the spraying quality of the flexible cover plate, and improve the product qualification rate. Moreover, cleaning the adsorption surface can reduce the impact of the accumulation of residual paint on the equipment, prevent the residual paint from blocking the vacuum adsorption holes on the adsorption table, thereby reducing the equipment failure rate, prolonging the service life, reducing the maintenance cost and downtime. In addition, the present invention cleans the adsorption surface during the process of the supporting box returning to the feeding area, without arranging separate downtime for the cleaning work, thereby reducing the downtime of the equipment, improving the utilization rate and production efficiency of the equipment.

[0009] Preferably, the driving structure includes a guide plate and a return spring. The return spring is connected to the rotation connection of the adsorption table and the supporting box. When the adsorption table is not affected by external forces, the return spring drives the adsorption table to abut against the supporting box, and the front end of the adsorption table is located in front of the supporting box. The guide plate is fixedly installed in the box body and extends in the front-rear direction. A first guide groove extending in the front-rear direction is formed on the guide plate. Lifting mechanisms are respectively arranged at the front and rear ends of the guide plate. When the supporting box moves from the feeding area to the discharging area, the supporting box moves along the top of the guide plate. When the supporting box moves from the discharging area to the feeding area, the guide plate pushes the adsorption table to turn over 180°, and the supporting box and the adsorption table move along the first guide groove.

[0010] The combination of the return spring and the guide plate is used to realize the automatic turning over of the adsorption table, without a complex mechanical transmission device or an electric turning mechanism, simplifying the overall structure and reducing the manufacturing cost and maintenance cost.

[0011] Preferably, the jacking mechanism includes an automatic telescopic rod fixedly installed in the box body and a jacking block fixedly connected to the driving end of the automatic telescopic rod. Support plates extend from the left and right sides of the support box respectively, and the jacking block drives the support box to move by jacking the support plates.

[0012] Preferably, the driving assembly includes a driving motor fixedly installed in the box body and a lead screw fixedly connected to the output end of the driving motor. Thrust plates in threaded cooperation with the lead screw are respectively arranged on the front and rear sides of the support box. The support box is slidably matched with the thrust plates in the vertical direction, and an inverted U-shaped groove buckled on the lead screw is formed at the bottom of the support box. The driving motor drives the lead screw to drive the thrust plates to move in the front and rear directions, and the thrust plates push the support box to move in the front and rear directions.

[0013] Preferably, the cleaning mechanism includes a cleaning block arranged in the support box and a power assembly one for driving the cleaning block to move in the front and rear directions. When the adsorption surface of the adsorption table is turned downward, the power assembly one drives the cleaning block to move in the front and rear directions to clean the adsorption surface of the adsorption table.

[0014] Preferably, a cleaning groove for placing a cleaning agent is arranged in the support box, and a power assembly two for driving the cleaning block to move in the vertical direction is provided. When the cleaning block is immersed in the cleaning groove, the cleaning agent in the cleaning groove cleans the cleaning block, and the cleaning block adsorbs the cleaning agent.

[0015] When the cleaning block is immersed in the cleaning groove, the cleaning agent in the cleaning groove cleans the cleaning block, and the cleaning agent strips or dissolves the paint adhered to the cleaning block, preventing the cleaning block from adhering residual impurities to the adsorption table when cleaning the adsorption table again; the cleaning block can also adsorb the cleaning agent in the cleaning groove, so that when cleaning the adsorption table, the cleaning agent cleans the paint on the adsorption table, improving the cleaning effect.

[0016] Preferably, a mounting plate is slidably connected in the support box along the front-rear direction. The cleaning block is rotatably connected to the mounting plate through a rotating shaft. A second guiding groove for the rotating shaft to move is formed in the guiding plate. The first power assembly includes a spring and a spring block. The spring extends along the front-rear direction and is connected between the mounting plate and the support box. A receiving groove and a fourth guiding groove are formed in the lifting block of the lifting mechanism located behind the guiding plate. The spring block is slidably connected in the fourth guiding groove along the vertical direction and is elastically connected to the fourth guiding groove. When the support box moves from the material discharging position to the material loading position, the rotating shaft moves along the fourth guiding groove to the second guiding groove. When the rotating shaft contacts the spring block, the spring block pushes the rotating shaft to drive the mounting plate and the cleaning block to move backward relative to the support box. When the rotating shaft passes over the spring block, the elastic force of the spring drives the mounting plate to drive the cleaning block to move forward.

[0017] Preferably, the second power assembly includes a guiding through groove formed in the mounting plate. The guiding through groove includes an inclined portion and a straight portion. The rotating shaft penetrates through the guiding through groove. When the cleaning block is located in the cleaning groove, the rotating shaft is located at the bottom end of the inclined portion. When the fourth guiding groove is flush with the straight portion, the bottom end of the receiving groove corresponds to the bottom end of the inclined portion. A third guiding groove is formed in the guiding plate. When the support box moves from the material loading position to the material discharging position, the guiding plate pushes the rotating shaft to move from the straight portion to the bottom end of the inclined portion, and the rotating shaft moves along the third guiding groove.

[0018] Preferably, a first toothed ring is arranged on the outer periphery of the rotating shaft, and a rack extending along the front-rear direction is arranged in the third guiding groove. When the rotating shaft moves along the third guiding groove, the first toothed ring meshes with the rack, and the first toothed ring drives the cleaning block to rotate in the cleaning groove.

[0019] By agitating the cleaning agent, the flow of the liquid is utilized to improve the cleaning efficiency and cleaning effect of the cleaning block, and each surface of the cleaning block can be cleaned.

[0020] Preferably, the straight portion is provided with a toothed section, and a second toothed ring adapted to the toothed section is arranged on the outer periphery of the rotating shaft. The radial cross-section of the cleaning block is square. After the second toothed ring drives the mounting plate to move a preset distance by pushing the toothed section, the second toothed ring rotates along the toothed section so that the cleaning block can replace the cleaning surface in contact with the adsorption table.

[0021] By the second toothed ring rotating along the second toothed section, the cleaning block is driven to rotate, so as to replace the cleaning surface of the cleaning block in contact with the adsorption table, avoid the residual paint wiped off on the cleaning surface from adhering to the adsorption table again, and further improve the cleaning effect.

[0022] The beneficial effects of the present invention are as follows: The cleaning mechanism of the present invention can clean the adsorption surface while the support box returns to the feeding position. Cleaning the adsorption surface can remove the residual paint, avoiding the pollution of the surface of the next flexible cover plate caused by the residual paint, resulting in defects or unevenness on the flexible cover plate, ensuring the spraying quality of the flexible cover plate, and improving the product qualification rate. Moreover, cleaning the adsorption surface can reduce the impact of the accumulation of residual paint on the equipment, prevent the residual paint from blocking the vacuum adsorption holes on the adsorption table, thereby reducing the equipment failure rate, extending the service life, and reducing the maintenance cost and downtime. In addition, the present invention cleans the adsorption surface during the process of the support box returning to the feeding position, without the need to arrange separate downtime for the cleaning work, thereby reducing the equipment downtime and improving the equipment utilization rate and production efficiency.

[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0033] As Figures 1 to 8 shown, it should be noted that, in order to facilitate the display of the position of the support box 2 at the front and rear ends of the guide plate 6, two support boxes 2 appear in the same drawing of the present invention, but in actual application, there is only one support box 2. A spraying device for producing a flexible cover plate of the present invention includes a box body 1, a spraying mechanism (not shown in the figure) arranged in the box body 1, and a support mechanism. The support mechanism includes a support box 2 and an adsorption table 3 rotatably connected to the support box 2. The adsorption table 3 is connected to an external vacuum pump (not shown in the figure). The adsorption table 3 is used for adsorbing the flexible cover plate 5, and a cleaning mechanism is arranged in the support box 2. A feeding place is arranged at the front side of the box body 1, a discharging place is arranged at the rear side of the box body 1, a driving component for driving the support box 2 to reciprocate between the feeding place and the discharging place is arranged in the box body 1, and a driving structure for driving the adsorption table 3 to turn over is also arranged in the box body 1.

[0034] In the initial state, the support box 2 and the adsorption table 3 are located at the feeding place, and the adsorption table 3 is attached to the top of the support box 2 and is in a horizontal state. The flexible cover plate 5 is placed on the adsorption surface of the adsorption table 3, and the adsorption table 3 adsorbs the flexible cover plate 5. Then, the driving component drives the support box 2 to move from the feeding place to the discharging place. When it moves below the spraying mechanism, the spraying mechanism sprays the flexible cover plate 5. After spraying is completed, it continues to move to the discharging place for discharging. After the sprayed flexible cover plate 5 is taken off, the driving component drives the support box 2 to move from the discharging place to the feeding place, and the driving structure drives the adsorption table 3 to turn over 180°, so that its adsorption surface faces downwards, and the cleaning mechanism is controlled to clean the adsorption surface of the adsorption table 3.

[0035] The cleaning mechanism of the present invention can clean the adsorption surface while the support box 2 returns to the loading place. Cleaning the adsorption surface can remove residual paint, and prevent the residual paint from contaminating the surface of the next flexible cover plate 5, resulting in defects or unevenness on the flexible cover plate 5, ensuring the spraying quality of the flexible cover plate 5, and improving the product qualification rate; and cleaning the adsorption surface can reduce the impact of the accumulation of residual paint on the equipment, and prevent residual paint from clogging the vacuum adsorption holes on the adsorption table 3, thereby reducing the equipment failure rate, extending the service life, and reducing maintenance costs and downtime; in addition, the present invention cleans the adsorption surface during the process of the support box 2 returning to the loading place, and there is no need to arrange downtime separately for cleaning work, thereby reducing the downtime of the equipment and improving the utilization rate and production efficiency of the equipment.

[0036] like Figure 2 、 Figure 3 and Figure 5 As shown, the driving structure includes a guide plate 6 and a return spring 31. The return spring 31 is connected to the rotation connection between the adsorption platform 3 and the support box 2. When the adsorption platform 3 is not subjected to external force, the return spring 31 drives the adsorption platform 3 to rest on the support box 2, and the front end of the adsorption platform 3 is located in front of the support box 2. As an example, the return spring 31 is a torsion spring. There are two guide plates 6 symmetrically arranged on the left and right sides and fixedly installed in the box body 1. The guide plates 6 extend in the front-to-back direction, and a guide groove 61 extending in the front-to-back direction is provided on the guide plates 6. Support plates 20 adapted to the guide groove 61 extend from the left and right sides of the support box 2 respectively. Lifting mechanisms are provided at the front and rear ends of the guide plate 6.

[0037] When the support box 2 is located in front of the guide plate 6, the lifting mechanism at the front end of the guide plate 6 lifts the support box 2 upward until the bottom of the support plates 20 on both sides of the support box 2 are flush with the top of the guide plate 6. The control drive assembly drives the support box 2 to move from the loading position to the unloading position. When the support box 2 moves along the top of the guide plate 6 to the unloading position, the support box 2 is located on the lifting mechanism at the rear end of the guide plate 6. The lifting mechanism is controlled to drive the support box 2 down to the position where the support plate 20 is aligned with the guide groove 61. Since the front end of the adsorption platform 3 is located in the front side of the support box 2, the guide plate 6 forms a blockage on the front end of the adsorption platform 3 during the descending process of the support box 2, thereby causing the adsorption platform 3 to rotate upward relative to the support box 2 to an inclined state. At this time, the adsorption of the flexible cover plate 5 is canceled, and the flexible cover plate 5 is removed, completing the unloading process of the flexible cover plate 5.

[0038] Then, the driving assembly is controlled to drive the support box 2 to move from the unloading position to the loading position, and the support plate 20 enters the guide groove 61. The adsorption platform 3 is flipped 180 degrees under the push of the guide plate 6 and then enters the guide groove 61. The guide groove 61 keeps the adsorption platform 3 in a horizontal state with the adsorption surface facing downward, so that the cleaning mechanism can clean the adsorption surface.

[0039] When the support box 2 moves to the adsorption table 3 disengaging from the guide groove 61, under the action of the return spring 31, the adsorption table 3 flips 180° to fit on the top of the support box 2, restoring the initial state with the adsorption surface facing upward.

[0040] The lifting mechanism includes automatic telescopic rods 7 symmetrically arranged on the left and right sides of the support box 2 and a lifting block 71 fixedly connected to the driving end of the automatic telescopic rod 7. The automatic telescopic rod 7 is fixedly installed in the box body 1. The automatic telescopic rod 7 drives the lifting block 71 to move up and down, and the lifting block 71 drives the support box 2 to move through the lifting support plate 20.

[0041] As Figure 3 and Figure 4 shown, the driving assembly includes two driving motors (not shown in the figure) symmetrically arranged on the left and right and a lead screw 8 fixedly connected to the output end of the driving motor. The driving motor is fixedly installed in the box body 1. Thrust plates 81 threadedly engaged with the lead screw 8 are respectively arranged on the front and rear sides of the support box 2. The support box 2 is slidably engaged with the thrust plate 81 in the vertical direction, and an inverted U-shaped groove 21 buckled on the lead screw 8 is provided at the bottom of the support box 2. When the lifting mechanism drives the support box 2 to move up and down, the support box 2 can move up and down relative to the thrust plate 81 and the lead screw 8 without being interfered. When the driving motor drives the lead screw 8 to drive the thrust plate 81 to move in the front and rear directions, the thrust plate 81 pushes the support box 2 to move in the front and rear directions.

[0042] The cleaning mechanism includes a cleaning block 9 arranged in the support box 2 and a power assembly one for driving the cleaning block 9 to move in the front and rear directions. When the adsorption surface of the adsorption table 3 flips to the lower side, the power assembly one drives the cleaning block 9 to move in the front and rear directions to clean the adsorption surface of the adsorption table 3.

[0043] As Figure 5 shown, a cleaning tank 22 for placing a cleaning agent and a power assembly two for driving the cleaning block 9 to move in the vertical direction are arranged in the support box 2. When the cleaning block 9 is immersed in the cleaning tank 22, the cleaning agent in the cleaning tank 22 cleans the cleaning block 9, and the cleaning agent strips or dissolves the paint adhered to the cleaning block 9, preventing the cleaning block 9 from adhering residual impurities to the adsorption table 3 when cleaning the adsorption table 3 again. The cleaning block 9 can also adsorb the cleaning agent in the cleaning tank 22, so that when cleaning the adsorption table 3, the cleaning agent cleans the paint on the adsorption table 3, improving the cleaning effect.

[0044] As Figure 3 、 Figure 4 、 Figures 6 to 8As shown, two mounting plates 4 are symmetrically disposed within the support box 2, and the two mounting plates 4 are slidably connected to the support box 2 in the front-to-back direction. The cleaning block 9 is rotatably connected to the two mounting plates 4 via a rotating shaft 91, which extends through the corresponding mounting plate 4 to the outside of the support box 2. The guide plate 6 defines a guide slot 62 for the rotation of the rotating shaft 91. The first power assembly comprises a spring 41 and a spring block 72. The spring 41 extends in the front-to-back direction and is connected between the mounting plate 4 and the support box 2. The lifting block 71 of the lifting mechanism, located behind the guide plate 6, defines a receiving slot 73 corresponding to the position of the rotating shaft 91. When the support box 2 moves from the front to the back and away from the guide plate 6, the lifting block 71 supports the support box 2 via the support plate 20, with the rotating shaft 91 located within the receiving slot 73. The lifting block 71 also defines a guide slot 74 that is flush with and connected to the guide slot 62. The spring block 72 vertically slides within the guide slot 74 and is elastically connected to the guide slot 74.

[0045] When the support box 2 moves from the unloading position to the loading position, the support plate 20 aligns with the guide groove 1 61 and moves along the guide groove 1 61. The guide groove 4 74 is flush with and connected to the guide groove 2 62. The rotating shaft 91 moves along the guide groove 4 74. When the rotating shaft 91 contacts the elastic block 72, the elastic block 72 blocks the forward movement of the rotating shaft 91. As a result, during the forward movement of the support box 2 and the adsorption platform 3, the mounting plate 4 moves backward relative to the support box 2. The spring 41 between the mounting plate 4 and the support box 2 is stretched. During the forward movement of the adsorption platform 3, the cleaning block 9 on the mounting plate 4 is passed, and the cleaning block 9 cleans the adsorption surface from front to back. When the pulling force of the spring 41 on the mounting plate 4 is greater than the blocking force of the elastic block 72 on the rotating shaft 91, the rotating shaft 91 passes over the elastic block 72. The elastic force of the spring 41 drives the mounting plate 4 to drive the cleaning block 9 to move forward and reset. During the forward movement of the cleaning block 9, the adsorption surface is cleaned again.

[0046] Continue reading Figure 3 、 Figure 4 、 Figures 6 to 8 Power assembly 2 includes a guide slot 42 formed on mounting plate 4. Guide slot 42 comprises an inclined portion 421 and a straight portion 422. Rotational shaft 91 extends through guide slot 42. Support box 2 includes a relief slot 23 corresponding to guide slot 42. When cleaning block 9 is positioned within cleaning slot 22, rotational shaft 91 is positioned at the bottom of inclined portion 421. When support plate 20 is positioned on lifting block 71 behind guide plate 6, guide slot 44 74 is flush with the straight portion 422 of guide slot 42, and the bottom of receiving slot 73 aligns with the bottom of inclined portion 421.

[0047] When the support box 2 moves from the blanking position to the feeding position, the groove wall of the accommodating groove 73 blocks the advancement of the rotating shaft 91, causing the rotating shaft 91 to move upward along the inclined portion 421 to the straight portion 422. That is, the rotating shaft 91 drives the cleaning block 9 to disengage from the cleaning groove 22. When the rotating shaft 91 moves along the straight portion 422 to the end of the straight portion 422, the cleaning block 9 moves to a position where it can contact the adsorption surface. At this time, the rotating shaft 91 follows the movement of the support box 2. When the rotating shaft 91 contacts the elastic block 72, the rotating shaft 91 is blocked by the elastic block 72 and drives the mounting plate 4 to move backward relative to the support box 2, thereby realizing the cleaning of the adsorption surface of the adsorption table 3 by the cleaning block 9.

[0048] As Figures 2 to 4 shown, when the support box 2 moves from the blanking position to the front side of the guide plate 6, the rotating shaft 91 is still located in the straight portion 422 of the guide through groove 42. When the support box 2 moves from the front side of the guide plate 6 to the blanking position, the front end of the guide plate 6 blocks the advancement of the rotating shaft 91, causing the rotating shaft 91 to move along the straight portion 422 to the bottom end of the inclined portion 421, so that the cleaning block 9 is immersed in the cleaning agent in the cleaning groove 22 for cleaning. A third guide groove 63 is formed on the guide plate 6. At this time, the rotating shaft 91 is aligned with the third guide groove 63 on the guide plate 6 and moves along the third guide groove 63, so that the cleaning block 9 is continuously immersed in the cleaning agent.

[0049] A first gear ring (not shown in the figure) is provided on the outer periphery of the rotating shaft 91, and a rack (not shown in the figure) extending in the front-rear direction is provided in the third guide groove 63. When the rotating shaft 91 moves along the third guide groove 63, the first gear ring meshes with the rack, and the first gear ring drives the cleaning block 9 to rotate in the cleaning groove 22. By stirring the cleaning agent, the cleaning efficiency and cleaning effect of the cleaning block 9 are improved by using the flow of the liquid, and each surface of the cleaning block 9 can be cleaned.

[0050] A tooth section 43 is provided at a position near the rear end of the straight portion 422, and a second gear ring 92 adapted to the tooth section 43 is provided on the outer periphery of the rotating shaft 91. The radial cross-section of the cleaning block 9 is square. When the rotating shaft 91 moves upward along the inclined portion 421 to the straight portion 422 and moves along the straight portion 422 until the second gear ring 92 contacts the tooth section 43, the rotating shaft 91 moves synchronously with the support box 2. When the rotating shaft 91 contacts the elastic block 72, the elastic block 72 blocks the advancement of the rotating shaft 91, and the rotating shaft 91 pushes the tooth section 43 to make the mounting plate 4 move backward relative to the support box 2, realizing the wiping of the adsorption table 3 by the cleaning block 9 from front to back.

[0051] When the tension of the spring 41 between the mounting plate 4 and the support box 2 on the mounting plate 4 gradually increases, the pushing force between the spring block 72 and the rotating shaft 91 also gradually increases. The rotating shaft 91 overcomes the resistance of the adsorption platform 3 to the rotation of the cleaning block 9, so that the gear ring 2 92 rotates along the tooth segment 43 2, thereby driving the cleaning block 9 to rotate, and realizing the replacement of the cleaning surface of the cleaning block 9 in contact with the adsorption platform 3. In the process of the rotating shaft 91 moving forward over the spring block 72, the cleaning block 9 wipes the adsorption platform 3 from back to front, and the cleaning surface wiped this time is different from the cleaning surface wiped last time, so as to avoid the residual paint wiped off the cleaning surface from adhering to the adsorption platform 3 again, thereby further improving the cleaning effect.

[0052] The specific working principle of the spray coating device for producing flexible cover sheets of the present invention is as follows: in the initial state, the support box 2 and the adsorption platform 3 are located at the loading position, and the adsorption platform 3 is attached to the top of the support box 2 and is in a horizontal state. The flexible cover sheet 5 is placed on the adsorption surface of the adsorption platform 3, and the adsorption platform 3 adsorbs the flexible cover sheet 5; The lifting mechanism on the front side of the control guide plate 6 lifts the support box 2 until the bottom of the support plate 20 is flush with the top of the guide plate 6, and the control drive assembly drives the support box 2 to move backward. The support plates 20 on both sides of the support box 2 move backward along the top of the guide plate 6, and in the process of the support box 2 moving backward, the front end of the guide plate 6 blocks the advancement of the rotating shaft 91, so that the rotating shaft 91 moves along the straight portion 422 of the guide groove 42 to the bottom end of the inclined portion 421, so that the cleaning block 9 is immersed in the cleaning tank 22, and then the rotating shaft 91 moves along the guide groove three 63, and the rack drives the gear ring one to drive the cleaning block 9 to rotate in the cleaning tank 22; When the support box 2 moves along the top of the guide plate 6 to the unloading position, the support plate 20 is located on the jacking mechanism on the rear side of the guide plate 6, and the rotating shaft 91 falls into the accommodating groove 73. The jacking mechanism is controlled to drive the support box 2 to descend to the position where the support plate 20 is aligned with the guide groove 61. Since the front end of the adsorption platform 3 is located at the front side of the support box 2, the guide plate 6 forms a block on the front end of the adsorption platform 3 during the descending process of the support box 2, so that the adsorption platform 3 rotates upward to an inclined state relative to the support box 2, canceling the adsorption of the flexible cover plate 5, and the flexible cover plate 5 is removed; The control drive assembly drives the support box 2 to move forward. The support plate 20 enters the first guide groove 61. After the adsorption table 3 is flipped 180° under the pushing of the guide plate 6, it also enters the first guide groove 61. The first guide groove 61 keeps the adsorption table 3 in a horizontal state with the adsorption surface facing down. When the support box 2 moves forward, the groove wall of the receiving groove 73 blocks the advancement of the rotating shaft 91, causing the rotating shaft 91 to move upward along the inclined portion 421 to the straight portion 422, that is, the rotating shaft 91 drives the cleaning block 9 to disengage from the cleaning groove 22. When the rotating shaft 91 moves along the straight portion 422 to the end of the straight portion 422, the cleaning block 9 moves to a position where it can contact the adsorption surface. At this time, the rotating shaft 91 follows the support box 2 to move. When the rotating shaft 91 contacts the elastic block 72, the rotating shaft 91 drives the mounting plate 4 to move backward relative to the support box 2 under the blocking of the elastic block 72, realizing the cleaning of the adsorption surface of the adsorption table 3 by the cleaning block 9. When the rotating shaft 91 passes over the elastic block 72, the elastic force of the spring 41 drives the mounting plate 4 to drive the cleaning block 9 to move forward to reset. During the forward movement of the cleaning block 9, the adsorption surface is cleaned again.
