[0001] This utility model relates to the field of diffusion plate production technology, specifically to a coating device for diffusion plates. Background Technology

[0002] To prevent the diffuser plate from becoming statically charged during use, an antistatic liquid is sprayed onto its surface during production. The antistatic liquid then solidifies and condenses into a protective film on the diffuser plate, thus giving it antistatic properties. A coating device is required when spraying the antistatic liquid onto the diffuser plate.

[0003] The existing coating equipment has been found to have limited functionality, only capable of spraying antistatic liquid onto the diffusion plate, and lacking the function of drying and curing the antistatic liquid after coating. Therefore, improvements are needed.

[0004] Therefore, it is necessary to invent a coating device for a diffusion plate. Summary of the Invention

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] See attached document Figure 1 -Appendix Figure 8 The present invention provides a coating device for a diffusion plate, comprising:

[0037] Base 1, U-shaped frame 1 2 and U-shaped frame 2 3 are fixedly connected to base 1, baffle 1 4 is fixedly connected to both sides of U-shaped frame 1 2, and baffle 2 5 is fixedly connected to both sides of U-shaped frame 2 3.

[0038] Two electric slide rails 6 are provided. Both electric slide rails 6 are fixedly connected to the top of the base 1. Both electric slide rails 6 pass through the U-shaped frame 1 2 and the U-shaped frame 2 3. Both electric slide rails 6 are provided with sliders 7. The top of the two sliders 7 is fixedly connected with a placement plate 8. The placement plate 8 is provided with a placement groove.

[0039] A rotating shaft 9 is embedded in a U-shaped frame 3. A UV curing lamp 10 is provided at the bottom of the rotating shaft 9. Three connecting rods 11 are fixedly connected between the UV curing lamp 10 and the rotating shaft 9.

[0040] Guide rod 12 is fixedly connected to the front side of U-shaped frame 2 3. A moving block 13 is slidably provided on guide rod 12. A toothed plate 14 is fixedly connected to the top of moving block 13. A gear 15 is provided on the top of toothed plate 14 and meshes with it. The gear 15 is fixedly sleeved on the outside of the front end of rotating shaft 1 9.

[0041] The electric push rod 16 is fixedly connected to the front side of the U-shaped frame 2 3, and the end of the electric push rod 16 is fixedly connected to one side of the moving block 13.

[0042] Coating assembly, used for coating the diffusion plate;

[0043] The guide rod 12 has a T-shaped cross-section;

[0044] In this embodiment, an ultraviolet curing lamp 10 is designed so that after the antistatic liquid is sprayed onto the diffuser plate, the ultraviolet curing lamp 10 can directly dry and cure the antistatic liquid on the surface of the diffuser plate. In this way, the device has the function of drying and curing the antistatic liquid.

[0045] To achieve the purpose of spray coating, this device adopts the following technical solution: The coating assembly includes a motor 17, which is fixedly connected to the rear side of the U-shaped frame 2. The output shaft of the motor 17 is fixedly connected to a reciprocating screw 18, which passes through the U-shaped frame 2. A sliding seat 19 is sleeved on the outside of the reciprocating screw 18. The sliding seat 19 and the reciprocating screw 18 are connected through a ball screw pair. A coating head 20 is fixedly connected to one side of the sliding seat 19. A storage tank 21 is fixedly connected to one side of a baffle 4. A pump body 22 is fixedly connected to the top of the U-shaped frame 2. A hose 23 is fixedly connected to the outlet of the pump body 22. The end of the hose 23 is fixedly connected to the coating head 20. The inlet of the pump body 22 is fixedly connected to a pipe 24, the end of which extends into the storage tank 21. A hose 23 passes through the top of the U-shaped frame 2 and is fixedly connected thereto. The pipe 24 passes through the top of the storage tank 21 and is fixedly connected thereto. When the pump body 22 is working, the antistatic liquid can enter the coating head 20 and be sprayed onto the diffuser plate under the action of the pipe 24 and hose 23. At this time, the motor 17 can also be controlled to work. The motor 17 drives the reciprocating screw 18 to rotate. The rotation of the reciprocating screw 18 drives the sliding seat 19 to move back and forth continuously, thereby moving the coating head 20 back and forth. In addition, the diffuser plate moves to the right, so that the antistatic liquid can be sprayed evenly onto the diffuser plate.

[0046] In order to achieve the purpose of stable movement of the sliding seat 19, the following technical solution is adopted in this device: a limiting rod 25 is fixedly connected in the U-shaped frame 2, the limiting rod 25 passes through the sliding seat 19 and slides in contact with it, and the limiting rod 25 can ensure the stable movement of the sliding seat 19.

[0047] In order to achieve the purpose of adding liquid, the device adopts the following technical solution: a feeding pipe 26 is fixedly embedded on the top of the storage tank 21, and the feeding pipe 26 can add antistatic liquid into the storage tank 21;

[0048] In order to prevent the tilt angle of the UV curing lamp 10 from changing arbitrarily, the device adopts the following technical solution: the rotating shaft 9 is connected to the U-shaped frame 3 with a damping bearing. The damping bearing connection can prevent the rotating shaft 9 from rotating arbitrarily, thereby preventing the tilt angle of the UV curing lamp 10 from changing arbitrarily.

[0049] In order to reduce wear, the device adopts the following technical solution: the reciprocating screw 18 and the U-shaped frame 2 are connected by bearings, which can reduce wear.

[0050] The usage process of this utility model is as follows: When it is necessary to spray antistatic liquid onto the diffuser plate, the antistatic liquid is added to the storage tank 21 through the feeding pipe 26. Then, the diffuser plate is placed in the placement slot. Next, the two electric slide rails 6 are controlled to work, so that the two sliders 7 and the placement plate 8 can move to the right. This allows the diffuser plate to pass through the U-shaped frame 2. At the same time, the pump body 22 is controlled to work. Then, under the action of the pipe 24 and the hose 23, the antistatic liquid can enter the coating head 20 and be sprayed onto the diffuser plate. At this time, the motor 17 can also be controlled to work. The motor 17 drives the reciprocating screw 18 to rotate. The rotation of the reciprocating screw 18 drives the sliding seat 19 to move back and forth continuously, thereby moving the coating head 20 back and forth. In addition, the diffuser plate moves to the right, so that the antistatic liquid can be sprayed evenly onto the diffuser plate, thus completing the spraying work.

[0051] After the spraying is completed, the electric slide rail 6 continues to work, allowing the diffuser plate to continue moving to the right and pass through the U-shaped frame 3. At this time, the ultraviolet curing lamp 10 is controlled to work, so that the ultraviolet light can irradiate the diffuser plate. In addition, the diffuser plate moves to the right, so that the antistatic liquid can be dried and cured evenly. During drying and curing, the electric slide rail 6 can be controlled to slow down the movement speed of the diffuser plate, thereby ensuring the curing effect. In addition, the electric push rod 16 can be controlled to move the moving block 13 and the toothed plate 14 to the left. The movement of the toothed plate 14 will cause the gear 15 to rotate. The rotation of the gear 15 will drive the rotating shaft 9 to rotate, which will cause the ultraviolet curing lamp 10 to rotate, thus making the ultraviolet curing lamp 10 tilted. In this way, the ultraviolet light will not irradiate the diffuser plate vertically but at an angle, thus increasing the irradiated area. In use, the irradiated area can be appropriately increased according to the amount of antistatic liquid sprayed. At the same moving speed, the irradiation time of the next area will be longer, thereby ensuring that the antistatic liquid is thoroughly dried and cured.

[0052] Once curing is complete, the electric slide rail 6 will transport the diffusion plate to the right side of the device. Then, the diffusion plate can be removed manually. Then, control the electric slide rail 6 to move the slider 7 and the placement plate 8 to the left to reset. Then, continue the coating process using the same principle.

[0053] It is worth noting that there is a notch on the left side of the placement slot, which makes it easy to remove the diffuser plate.

[0054] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
