Description

Technical Field

[0001] The present invention relates to the technical field of spraying devices, and in particular to a spraying device for producing flexible cover plates. Background Art

[0002] Flexible cover plate spraying technology is a key surface treatment process in modern manufacturing, particularly in flexible electronics, display panels, and automotive parts. During the spraying process, uneven atomization, improper spray gun angle, or excessive spray pressure can cause paint to splash or drip onto the platform where the flexible cover is placed, contaminating the platform.

[0003] A Chinese patent with announcement number CN222490592U discloses a laminating device for the production of flexible display screens, including a positioning substrate, a positioning shell, a groove, a suction cup and a vacuum pump. The vacuum pump connecting pipe can be connected to the external vacuum pump first, 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 several groups of suction cups to avoid displacement during lamination. By setting a shell and reserving a guide groove between the shell and the positioning shell, when the display screen is sprayed with lamination, the laminating paint dripping from the display screen will flow into the guide groove and then be discharged from the two groups of guide pipes. When the valve is open, the laminating paint will flow into the inside of the recovery box, thereby achieving the effect of collecting excess laminating paint to avoid dripping around the device and affecting environmental hygiene.

[0004] The above patent reduces the contamination of the device by the coating material by providing a guide groove to collect the dripping coating paint into a recovery box. However, in actual use, there may be coating residue on the adsorption table where the flexible cover is placed. Moreover, some coatings are sticky. Even if the coating flows along the guide groove, it will form residue on the adsorption table. These residual coatings gradually accumulate and may cause blockage of the vacuum channel or adsorption groove on the adsorption table, and even affect the flatness of the subsequent flexible cover placed on the adsorption table, resulting in uneven coating on the flexible cover and affecting the production quality of the flexible cover.

[0005] Therefore, the art needs a spraying device for producing flexible cover plates to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 8 As 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 figure of the present invention, but in actual application, there is only one support box 2. A spraying device for the production of flexible cover plates of the present invention comprises a box body 1, a spraying mechanism (not shown in the figure) and a support mechanism arranged in the box body 1, the support mechanism comprises 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 to adsorb the flexible cover plate 5, and a cleaning mechanism is arranged in the support box 2. A loading place is arranged on the front side of the box body 1, and a unloading place is arranged on the rear side. A driving component for driving the support box 2 to reciprocate between the loading place and the unloading place is arranged in the box body 1. A driving structure for driving the adsorption table 3 to flip is also arranged in the box body 1.

[0039] 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 plate 5 is placed on the adsorption surface of the adsorption platform 3, and the adsorption platform 3 adsorbs the flexible cover plate 5. Then, the driving component drives the support box 2 to move from the loading position to the lower loading position. When it moves to the bottom of the spraying mechanism, the spraying mechanism sprays the flexible cover plate 5. After the spraying is completed, it continues to move to the unloading position for unloading. After the sprayed flexible cover plate 5 is removed, the driving component drives the support box 2 to move from the unloading position to the loading position, and the driving structure drives the adsorption platform 3 to flip 180° until its adsorption surface is facing downward, and the cleaning mechanism is controlled to clean the adsorption surface of the adsorption platform 3.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] When the support box 2 moves to the point where the adsorption platform 3 is out of the guide groove 61 , the adsorption platform 3 is flipped 180° under the action of the return spring 31 to fit against the top of the support box 2 , restoring the initial state with the adsorption surface facing upward.

[0045] The lifting mechanism includes an automatic telescopic rod 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.

[0046] like Figure 3 and Figure 4 As shown, the drive assembly includes two drive motors (not shown in the figure) arranged symmetrically on the left and right and a lead screw 8 fixedly connected to the output end of the drive motor. The drive motor is fixedly installed in the box body 1. The front and rear sides of the support box 2 are respectively provided with push plates 81 that are threadedly engaged with the lead screw 8. The support box 2 slides with the push plates 81 in the vertical direction, and the bottom of the support box 2 is provided with an inverted U-shaped groove 21 that is buckled on the lead screw 8. 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 push plates 81 and the lead screw 8 without interference. When the drive motor drives the lead screw 8 to drive the push plate 81 to move in the front-back direction, the push plate 81 pushes the support box 2 to move in the front-back direction.

[0047] The cleaning mechanism includes a cleaning block 9 arranged in the support box 2 and a power component 1 that drives the cleaning block 9 to move in the front and rear directions. When the adsorption surface of the adsorption table 3 is flipped to the bottom, the power component 1 drives the cleaning block 9 to move in the front and rear directions to clean the adsorption surface of the adsorption table 3.

[0048] like Figure 5 As shown, the support box 2 is provided with a cleaning tank 22 for placing a cleaning agent and a power assembly 2 for driving the cleaning block 9 to move vertically. 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, peeling off or dissolving the paint adhered to the cleaning block 9, thereby preventing the cleaning block 9 from adhering to the adsorption table 3 when cleaning the adsorption table 3 again. The cleaning block 9 can also absorb 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, thereby improving the cleaning effect.

[0049] like 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.

[0050] 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.

[0051] 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.

[0052] When the support box 2 moves from the unloading position to the loading position, the groove wall of the accommodating groove 73 blocks the advancement of the rotating shaft 91, so that the rotating shaft 91 moves upward along the inclined portion 421 to the straight portion 422, that is, the rotating shaft 91 drives the cleaning block 9 to escape 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 moves with the support box 2. When the rotating shaft 91 contacts the spring block 72, the rotating shaft 91 drives the mounting plate 4 to move backward relative to the support box 2 under the obstruction of the spring block 72, thereby realizing the cleaning of the adsorption surface of the adsorption platform 3 by the cleaning block 9.

[0053] like Figures 2 to 4 As shown, when support box 2 moves from the feed position to the front side of guide plate 6, rotating shaft 91 remains located in straight portion 422 of guide slot 42. As support box 2 moves from the front side of guide plate 6 to the feed position, the front end of guide plate 6 blocks the forward movement of rotating shaft 91, causing rotating shaft 91 to move along straight portion 422 to the bottom end of inclined portion 421, thereby immersing cleaning block 9 in the detergent in cleaning tank 22 for cleaning. Guide slot 3 63 is defined in guide plate 6. At this time, rotating shaft 91 aligns with guide slot 3 63 of guide plate 6 and moves along guide slot 3 63, allowing cleaning block 9 to remain immersed in the detergent.

[0054] A ring gear (not shown) is disposed on the outer periphery of the rotating shaft 91, and a rack (not shown) extending in the front-to-rear direction is disposed within the guide groove (3) 63. When the rotating shaft 91 moves along the guide groove (3) 63, the ring gear (1) engages with the rack, thereby driving the cleaning block 9 to rotate within the cleaning groove 22. This agitation of the cleaning agent utilizes the flow of the liquid to improve the cleaning efficiency and effectiveness of the cleaning block 9, and ensures that every surface of the cleaning block 9 is cleaned.

[0055] A tooth segment 43 is provided near the rear end of the straight portion 422, and a second gear ring 92 adapted to the tooth segment 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 segment 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 forward movement of the rotating shaft 91. The rotating shaft 91 pushes the tooth segment 43 to move the mounting plate 4 backward relative to the support box 2, thereby realizing that the cleaning block 9 wipes the adsorption table 3 from front to back.

[0056] 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.

[0057] 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;

[0058] 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;

[0059] 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;

[0060] The control driving assembly drives the support box 2 to move forward, the support plate 20 enters the guide groove 61, and the adsorption platform 3 turns 180 degrees under the push of the guide plate 6 and also enters the guide groove 61. The guide groove 61 keeps the adsorption platform 3 in a horizontal state with the adsorption surface facing downward, and when the support box 2 moves forward, the groove wall of the accommodating groove 73 blocks the advancement of the rotating shaft 91, so that the rotating shaft 91 moves upward along the inclined portion 421 to the straight portion 422, that is, the rotating shaft 91 drives the cleaning block 9 to escape from the cleaning groove 22, and the rotating shaft 91 moves along the straight portion 422. When 22 moves 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 moves with the support box 2. When the rotating shaft 91 contacts the spring block 72, the rotating shaft 91 drives the mounting plate 4 to move backward relative to the support box 2 under the obstruction of the spring block 72, so that the cleaning block 9 cleans the adsorption surface of the adsorption table 3. When the rotating shaft 91 passes over the spring 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.

A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
