Technical Field
[0001] This invention relates to the field of coating technology, and more particularly to coating equipment for LED display screen manufacturing. Background Technology
[0002] With the rapid development of people's living standards, LED displays are being used more and more widely in people's lives. LED displays are a tool used to display data, videos and other information. During the processing of LED displays, a coating device is needed to coat the LED display. On the one hand, this protects the surface of the LED display and prevents damage to the surface. On the other hand, it makes the display look newer when it leaves the factory, increasing customers' desire to order and purchase the display.
[0003] Existing LED display screen coating equipment still has many shortcomings in use. The existing equipment is slow in coating the display screen, the coating quality is poor, and there are a lot of air bubbles between the film and the screen after coating, resulting in poor screen appearance and performance. In addition, the equipment has a low degree of automation, is time-consuming and labor-intensive, and the film does not adhere firmly to the display screen after coating, making it easy for the film to fall off. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, the present invention provides an LED display screen processing and production coating equipment, which effectively solves the problems in the prior art where there are a large number of air bubbles between the film and the screen after the display screen is coated, resulting in poor screen appearance and performance, as well as insufficient adhesion between the film and the display screen, and easy film peeling off.

[0008] Furthermore, parallel grooves corresponding to the drive column are respectively opened on both sides of the evenly divided section of the supporting slide plate, and an arc-shaped groove corresponding to the annular plate is opened in the middle of the evenly divided section of the supporting slide plate.
[0009] Furthermore, the support plate has positioning rods corresponding to the display screen in the grooves at both ends, and the lower end of the positioning rod is provided with a sliding column that is slidably connected to the support slide plate. A spring is provided between the positioning rod and the support slide plate and is sleeved and connected to the sliding column.
[0010] Furthermore, the coating structure also includes a rotating rod fixedly connected to the output end of the first motor. A first universal joint is provided on the rotating rod. A first sleeve is fixedly connected to one end of the first universal joint. A first sleeve rod is provided on the inner wall of the first sleeve. A second universal joint is provided at one end of the first sleeve rod. A transmission rod is fixedly connected to one end of the second universal joint. A support frame is rotatably connected to the processing plate. A limiting bracket rotatably connected to the transmission rod is provided on the support frame. A cam fixedly connected to the transmission rod is provided on the limiting bracket. A rotating wheel rotatably connected to the processing plate is correspondingly provided at the lower end of the cam. A first connecting rod is fixedly connected to the cam shaft. A second connecting rod is rotatably connected to the first connecting rod. Support rods are provided on both sides of the front end of the support frame. A second sliding rod is provided between the support rods. Second sliding cylinders are slidably connected to the second sliding rods. A fixing rod is provided between the second sliding cylinders. A support rod fixedly connected to the coating plate is provided at one end of the fixing rod. The lower end of the support rod is rotatably connected to the second connecting rod.
[0011] Furthermore, a pressure plate corresponding to the film-coated plate is fixedly connected to the front end of the support frame.
[0012] Furthermore, the blower structure also includes a first driving bevel gear fixedly connected to the rotating rod, the first driving bevel gear meshing with a first driven bevel gear, the first driven bevel gear being coaxially fixedly connected to a second driving sprocket, the second driving sprocket being belt-connected to a second driven sprocket, the second driven sprocket being coaxially fixedly connected to a second driving bevel gear, the second driving bevel gear meshing with a second driven bevel gear, the second driven bevel gear being coaxially fixedly connected to a crank, a square frame being provided inside the housing, a first rotating column being provided at both ends of the square frame and rotatably connected to the housing, a second motor being provided inside the square frame, a second rotating column being provided at both ends of the second motor and rotatably connected to the square frame, the upper end of the second motor being rotatably connected to the crank, and the output end of the second motor being fixedly connected to the fan.
[0013] Furthermore, a hot air blower corresponding to the fan is provided at the upper end of the housing.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] 1. This invention, by setting an intermittent transmission structure, sequentially transports the display screens within the evenly divided areas on the support slide plate to the lower end of the housing and the film plate for heating and pressing. Compared to conveyor belt transportation, which requires shutting down the conveyor belt during pressing, thus reducing work efficiency, the intermittent transportation of the display screens via the support slide plate provides stronger intervals and higher work efficiency.
[0016] 2. By setting up a film-coating structure and cooperating with an intermittent transmission structure, when the display screen is transported to the lower end of the film-coating plate for pressing, the drive column on the curved plate rotates once to drive the support slide plate for a fixed distance. Therefore, the display screen is pressed by utilizing the time difference between the intermittent movement of the support slide plate and the pressing of the film-coating plate. Since the film-coating plate is located at the corresponding adhesion position at the front end of the film and the front end of the display screen, after the film-coating plate is pressed down, it slides parallel to the display screen surface, which can quickly stick the film and the display screen together. Moreover, due to the adhesion and movement of the film-coating plate and the display screen, air bubbles between the film and the display screen can be expelled, improving the viewing experience and usage effect of the screen.
[0017] 3. By setting up a blower structure, the hot air blown out by the hot air blower has a larger heating range under the enhancement of the fan. By applying a certain temperature to the film, the adhesion of the film is improved, ensuring the firmness of the film and the display screen. In addition, the film becomes more flexible after being heated, which can greatly reduce the generation of air bubbles during the pressing process. Attached Figure Description

[0032] LED display screen processing and production coating equipment, such as Figure 1-13 As shown, the device includes a processing plate 1, on which a supporting slide plate 3 is provided. The supporting slide plate 3 is characterized by having several evenly spaced partitions. Each partition has a supporting plate 5 corresponding to a display screen at its upper end. The bottom of the processing plate 1 has an intermittent driving structure capable of driving the supporting slide plate 3 intermittently for one partition distance. The processing plate 1 also has a coating structure that cooperates with the intermittent driving structure. The coating structure includes a coating plate 29 that intermittently presses down and slides backward. The processing plate 1 also has a housing 6, inside which a blower structure that cooperates with the coating structure is provided. The blower structure includes a fan 45 whose airflow direction is continuously adjusted.
[0033] In use, the lower end of the processing plate 1 is provided with a base frame 2, which supports and fixes the entire device. The displays to be coated are placed sequentially on the support plate 5. One end of the support slide plate 3 is provided with a sliding pin 4 that slides and connects to the inner wall of the processing plate 1. The sliding pin 4 limits and supports the support slide plate 3, and the front end of the film is attached to the front end of the display. The intermittent drive structure is controlled to work. Since the intermittent drive structure and the blower structure are connected synchronously, when the displays on the support plate 5 are sequentially transported into the housing 6, the fan 45 blows air to apply a pressure to the film. A controlled temperature improves the adhesion of the film, ensuring the reliability of subsequent film application and screen bonding, and greatly reduces the generation of air bubbles during the bonding process. Therefore, when the screen on the support plate 5 is transported to the lower end of the film-coating plate 29, since the film-coating plate 29 is located at the corresponding bonding position of the front end of the film and the front end of the screen, the film and the screen can be quickly bonded together after the film-coating plate 29 is pressed down and slides parallel to the surface of the screen. Furthermore, since the film-coating plate 29 and the screen are bonded together, air bubbles between the film and the screen can be expelled, improving the viewing experience and usage effect of the screen.
[0034] like Figure 3 and 4 As shown, the intermittent drive structure includes a support plate 9 fixedly connected to the processing plate 1. A first motor 10 is provided on the support plate 9. A first drive sprocket 11 is fixedly connected to the output end of the first motor 10. A first driven sprocket 12 is connected to the first drive sprocket 11. An arc-shaped wheel 13 is coaxially fixedly connected to the first driven sprocket 12. A drive column 14 is provided at the narrow end of the arc-shaped wheel 13, and an annular plate 15 is provided at the thick end of the arc-shaped wheel 13.
[0035] Preferably, the support plate 9 supports and fixes the first motor 10. When the first motor 10 is working, the output end of the first motor 10 drives the first driving sprocket 11 to rotate. The first driving sprocket 11 drives the first driven sprocket 12 to rotate. The first driven sprocket 12 drives the arc wheel 13 to rotate. During the rotation of the arc wheel 13, the drive column 14 and the annular plate 15 rotate circumferentially, respectively.
[0036] like Figure 5 As shown, parallel grooves 50 corresponding to the drive column 14 are respectively opened on both sides of the evenly divided section of the supporting slide plate 3, and an arc groove 49 corresponding to the annular plate 15 is opened in the middle of the evenly divided section of the supporting slide plate 3.
[0037] Preferably, the drive column 14 and the annular plate 15 engage with the parallel groove 50 and the arc groove 49 respectively during the circumferential rotation, so that the drive support slide plate 3 intermittently runs a fixed distance, realizing the sequential replacement of the uniform partitions, which facilitates the coating of the display screen at different uniform partitions.
[0038] like Figure 5 and 6 As shown, the two end grooves of the support plate 5 are respectively provided with positioning rods 8 corresponding to the display screen. The lower end of the positioning rod 8 is provided with a sliding column 17 that is slidably connected to the support slide plate 3. A spring 18 is provided between the positioning rod 8 and the support slide plate 3 and is sleeved and connected to the sliding column 17.
[0039] Preferably, the positioning rod 8 positions the display screen on the support plate 5 to prevent the display screen from being misaligned, which could lead to deviations in the subsequent lamination. Under the limitation of the sliding column 17, the positioning rod 8 can retract into the grooves at both ends of the support plate 5 to avoid hindering the movement of the lamination plate 29. The spring 18 resets the positioning rod 8.
[0040] like Figure 7-10 As shown, the coating structure also includes a rotating rod 16 fixedly connected to the output end of the first motor 10. A first universal joint 19 is provided on the rotating rod 16. A first sleeve 22 is fixedly connected to one end of the first universal joint 19. A first sleeve rod 20 is provided on the inner wall of the first sleeve 22. A second universal joint 21 is provided at one end of the first sleeve rod 20. A transmission rod 48 is fixedly connected to one end of the second universal joint 21. A support frame 32 is rotatably connected to the processing plate 1. A limiting bracket 24 rotatably connected to the transmission rod 48 is provided on the support frame 32. The limiting bracket 24 is fixedly connected to the transmission rod 48. The cam 23 is connected to the machine plate 1. The lower end of the cam 23 is provided with a rotating wheel 25 that is rotatably connected to the machine plate 1. The first connecting rod 31 is fixedly connected to the axis of the cam 23. The first connecting rod 31 is rotatably connected to the second connecting rod 30. The front ends of the support frame 32 are respectively provided with support rods 47. The support rods 47 are provided with a second sliding rod 46. The second sliding rods 46 are respectively slidably connected with second sliding cylinders 27. The second sliding cylinders 27 are provided with a fixed rod 26. One end of the fixed rod 26 is provided with a support rod 28 that is fixedly connected to the film plate 29. The lower end of the support rod 28 is rotatably connected to the second connecting rod 30.
[0041] Preferably, the first motor 10 operates, and its output drives the rotating rod 16 to rotate. During this rotation, the rotating rod 16 drives the first universal joint 19 to rotate. Since the first universal joint 19 and the second universal joint 21 are connected via the first sleeve 22 and the first sleeve rod 20, the second universal joint 21 drives the transmission rod 48 to rotate during its rotation. The transmission rod 48 then drives the cam 23 to rotate. During rotation, the large-end arc-shaped surface of the cam 23 presses against the rotating wheel 25, causing the support frame 32 to deflect upwards. This allows the display screen to move to the lower end of the support frame 32, ensuring that the coating plate 29 presses against the display screen and the film. When the small-end arc surface of cam 23 is in contact with the rotating wheel 25 during rotation, the support frame 32 is parallel to the processing plate 1. The pressure plate 33 presses the adhesion between the display screen and the film, and the film-coated plate 29 is pressed against the front end of the display screen. Since the large-end arc surface of cam 23 is centered on the connection between the transmission rod 48 and cam 23, when the large-end arc surface of cam 23 is pressed and rotated with the rotating wheel 25, the film-coated plate 29 is pushed to the position of the pressure plate 33 under the action of the first connecting rod 31 and the second connecting rod 30. At this time, cam 23 rotates until the small-end arc surface is in contact with the rotating wheel 25. Since the small-end arc surface of cam 23 is also centered on the connection between the transmission rod 48 and cam 25, the support frame 32 is parallel to the processing plate 1. The pressure plate 33 presses the adhesion between the display screen and the film-coated plate 25, and the film-coated plate 29 is pressed against the front end of the display screen. The connection between cam 8 and cam 23 is the axis. Therefore, when cam 23 rotates, support frame 32 will not flip, and film plate 29 will move horizontally away from pressure plate 33. Film plate 29 is used to press the display screen and film together. At this time, support frame 32, film plate 29 and processing plate 1 are in a parallel state. Therefore, film plate 29 and display screen move in parallel and can squeeze out air bubbles in display screen and film. When cam 23 rotates, it drives first connecting rod 31 to rotate. During the rotation of first connecting rod 31, second connecting rod 30 is pulled to move. Second connecting rod 30 pulls support rod 28 and thus drives film plate 29. The 9th rod moves, and since the two ends of the fixed rod 26 are provided with second sliding cylinders 27, the second sliding cylinders 27 slide along the second sliding rod 46, thereby limiting the movement of the film-coated plate 29 and ensuring that the movement state of the film-coated plate 29 is always parallel to the support frame 32; and since the first sleeve rod 20 is provided with splines corresponding to the first sleeve 22, the first sleeve rod 20 does not affect the rotation of the first sleeve rod 20 during the sliding along the inner wall of the first sleeve 22, forming a telescopic universal joint coupling, which can effectively ensure that the first universal joint 19 can normally drive the rotation of the second universal joint 21 during the deflection of the support frame 32.
[0042] like Figure 10 As shown, the front end of the support frame 32 is fixedly connected to a pressure plate 33 corresponding to the film-coated plate 29.
[0043] Preferably, when the support frame 32 is parallel to the processing plate 1, the pressure plate 33 presses the connection between the display screen and the film, effectively cooperating with the film-coating plate 29 to move and press the display screen and the film together.
[0044] like Figure 11-13 As shown, the blower structure also includes a first driving bevel gear 37 fixedly connected to the rotating rod 16. The first driving bevel gear 37 meshes with a first driven bevel gear 36. The first driven bevel gear 36 is coaxially fixedly connected to a second driving sprocket 35. The second driving sprocket 35 is connected to a second driven sprocket 34. The second driven sprocket 34 is coaxially fixedly connected to a second driving bevel gear 39. The second driving bevel gear 39 meshes with a second driven bevel gear 38. The second driven bevel gear 38 is coaxially fixedly connected to a crank 40. A square frame 41 is provided inside the housing 6. The two ends of the square frame 41 are respectively provided with first rotating columns 42 rotatably connected to the housing 6. A second motor 44 is provided inside the square frame 41. The two ends of the second motor 44 are respectively provided with second rotating columns 43 rotatably connected to the square frame 41. The upper end of the second motor 44 is rotatably connected to the crank 40. The output end of the second motor 44 is fixedly connected to the fan 45.
[0045] Preferably, during the rotation of the rotating rod 16, it drives the first driving bevel gear 37 to rotate. The first driving bevel gear 37 drives the second driven bevel gear 38 to rotate. During the rotation of the first driven bevel gear 36, it drives the second driving sprocket 35 to rotate. The second driving sprocket 35 drives the second driven sprocket 34 to rotate via a chain. The second driven sprocket 34 drives the second driving bevel gear 39 to rotate. The second driving bevel gear 39 drives the second driven bevel gear 38 to rotate. The second driven bevel gear 38 drives the crank 40 to rotate. The crank 40... During the rotation, the second motor 44 is driven to swing under the limit of the second rotating column 43. In order to cooperate with the second motor 44 to swing in a large range, the second rotating columns 43 at both ends of the square frame 41 can limit the rotation of the square frame 41. The first rotating column 42 and the second rotating column 43 are arranged in a cross configuration. Therefore, under the limit of the first rotating column 42 and the second rotating column 43, the second motor 44 can swing in a circular cycle. The second motor 44 drives the fan 45 to rotate on its own axis and swing in a circular cycle, increasing the air blowing range of the fan 45 and improving the heating effect on the film.
[0046] like Figure 1 and 11 As shown, a hot air blower 7 corresponding to the fan 45 is installed at the upper end of the housing 6.
[0047] Preferably, the hot air blown out by the hot air blower 7 has a larger heating range under the enhancement of the fan 45. By applying a certain temperature to the film, the adhesion of the film is improved, ensuring the reliable adhesion between the film and the display screen.
[0048] The working process of the present invention is as follows: When the present invention is used, a base frame 2 is provided at the lower end of the processing plate 1. The base frame 2 plays a supporting and fixing role for the entire equipment. The display screens to be coated are placed on the support plate 5 in the evenly divided area in sequence. The positioning rod 8 is used to limit the display screen and to stick the front end of the film to the front end of the display screen.
[0049] The first motor 10 operates, and its output drives the first drive sprocket 11 to rotate. The first drive sprocket 11 drives the first driven sprocket 12 to rotate, and the first driven sprocket 12 drives the arc wheel 13 to rotate. During the rotation of the arc wheel 13, the drive column 14 and the annular plate 15 rotate circumferentially. During the circumferential rotation, the drive column 14 and the annular plate 15 mesh with the parallel groove 50 and the arc groove 49, respectively, thereby driving the support slide plate 3 to intermittently run a fixed distance, realizing the sequential replacement of the uniform zones, which facilitates the coating of the display screen at different uniform zones.
[0050] When the displays on the support plate 5 are sequentially moved into the housing 6, the first motor 10 operates. The output of the first motor 10 drives the rotating rod 16 to rotate. During the rotation of the rotating rod 16, the first driving bevel gear 37 rotates, which in turn drives the second driven bevel gear 38 to rotate. During the rotation of the first driven bevel gear 36, the second driving sprocket 35 rotates. The second driving sprocket 35 drives the second driven sprocket 34 to rotate via a chain. The second driven sprocket 34 drives the second driving bevel gear 39 to rotate, which in turn drives the second driven bevel gear 38 to rotate. The second driven bevel gear 38 drives the crank 40 to rotate, and during the rotation of the crank 40, the second motor 44 is driven to rotate in the second driving bevel gear 39. The second rotating column 43 swings under the limit of the second rotating column 43. In order to cooperate with the second motor 44 to swing in a large range of cycles, the second rotating column 43 at both ends of the square frame 41 can limit the rotation of the square frame 41. The first rotating column 42 and the second rotating column 43 are arranged in an intersecting manner. Therefore, under the limit of the first rotating column 42 and the second rotating column 43, the second motor 44 can swing in a circular cycle. The second motor 44 drives the fan 45 to rotate while swinging in a circular cycle, increasing the air blowing range of the fan 45. Due to the blowing effect of the hot air blower 7, the air blown out by the fan 45 applies a certain temperature to the film, improves the adhesion of the film, and ensures the reliability of the subsequent film and screen bonding. Moreover, due to the increased softness of the film after heating, the generation of air bubbles during the bonding process can be greatly reduced.
[0051] When the display screen on the support plate 5 is transported to the lower end of the laminating plate 29, since the laminating plate 29 is located at the corresponding bonding position of the front end of the film and the front end of the display screen, the pressure plate 33 presses the bonding position of the display screen and the film, which plays a positioning role. After the laminating plate 29 is pressed down, it slides down parallel along the surface of the display screen, which can quickly stick the film and the display screen together. Since the laminating plate 29 and the display screen are bonded together, the air bubbles between the film and the display screen can be expelled, improving the viewing experience and the use effect of the screen.
