Description

Technical Field

[0001] This invention relates to the field of LCD panel processing technology, specifically to an auxiliary guiding type LCD panel baking apparatus. Background Technology

[0002] An LCD panel is a display device with excellent color performance and high resolution. It can be used in home televisions, office projection displays, and indoor and outdoor advertising. During the LCD panel manufacturing process, baking is required. Specialized baking equipment is needed to bake the LCD panel. Baking the LCD panel can remove moisture and impurities from the panel, improving the yield of high-quality products while reducing the failure rate. During the baking process, after the moisture evaporates, it will condense inside the oven. If the oven continues to work at this time, it will affect the subsequent baking process, which may lead to uneven heating of the panel. The heat inside the oven and the smoke generated during the heating process will be difficult to expel, which will prolong the baking time. This will not only increase production costs, but may also affect production efficiency. To overcome the above-mentioned defects, prior art 1 (Chinese patent application number CN202020138931.9, application date 2020-01-20) provides a baking oven, which includes a support frame and a first support block and a second support block, both equipped with sliding grooves, with a heating plate located below the support frame. This baking oven has a simple structure and not only achieves baking of the food but also collects and processes the high-temperature moisture during baking, making it more efficient. Prior art 2 (Chinese patent application number CN201710166919.1, application date 2017-03-20) is a color filter substrate baking oven, which accelerates the removal of smoke in the baking oven, reduces the pollution caused by smoke condensation to the color filter substrate, and ensures the quality of the color filter substrate. After heating is complete, heat dissipates slowly. If a fan is used to assist in cooling, the screen components can be protected. However, the device in the above application does not have the effect of assisting in heat dissipation during use and has low working efficiency.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing LCD panel baking equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary guiding type LCD panel baking device to solve the problems mentioned in the background art, which do not have the effect of auxiliary heat dissipation and have low working efficiency during use.

The lower surface of the placement plate is fixedly connected to a lower connecting block, and the lower connecting block is slidably disposed on the surface of the long pin. The end of the long pin is fixedly connected to a partition plate, and the upper surface of the placement plate is provided with insertion slots at equal intervals. An auxiliary guiding type LCD panel baking apparatus further includes: An outer panel is fixedly connected to the outer wall of the outer shell, and a door panel that can slide up and down is slidably provided on the surface of the outer shell, and a fan is rotatably provided on the upper surface of the outer panel; A rotating shaft is fixedly connected to the output end of the motor, and a connecting plate is fixedly connected to the end of the rotating shaft, and a cam is fixedly connected to the middle of the rotating shaft. A limiting rod is fixedly connected to the inner wall of the housing, and a movable plate is slidably provided on the surface of the limiting rod, and a connecting rod is fixedly connected to the upper surface of the movable plate; A baffle, which is fixedly connected to the end of the connecting rod; An upper connecting block is fixedly connected to the upper surface of the placement plate; A breathable mesh is fixedly connected to the inside of the outer shell.

[0006] Preferably, auxiliary magnets are fixedly connected to the inner wall of the lower connecting block and the inner wall of the long pin, and the magnetic poles of adjacent auxiliary magnets are opposite, and the lower connecting blocks are symmetrically distributed about the center of the placement plate.

[0007] Preferably, toothed blocks are fixedly connected to the left and right surfaces of the placement plate at equal intervals, and a connecting shaft is rotatably provided inside the outer plate, and the connecting shaft passes through the interior of the outer plate.

[0008] Preferably, a gear is fixedly connected to the surface of the connecting shaft, and the gear meshes with the tooth block.

[0009] Preferably, the connecting shafts are evenly distributed inside the outer plate, and the upper end of the connecting shaft is fixedly connected to the fan.

[0010] Preferably, a first magnet is fixedly connected to the surface of the connecting plate, and a second magnet is fixedly connected to the upper surface of the upper connecting block.

[0011] Preferably, the second magnet has the same magnetic poles as the first magnet at adjacent positions, and the first magnet is distributed at equal angles on the surface of the connecting plate.

[0012] Preferably, the surface of the long pin is fixedly connected to a connecting spring that provides elastic reset, and the other side of the connecting spring is fixedly connected to the inner wall of the inner tube.

[0013] Preferably, the lower surface of the movable plate is in contact with the end of the cam, the front view of the limiting rod is an inverted "U" structure, and the limiting rod is symmetrically distributed about the center of the movable plate.

[0014] Preferably, the front view of the connecting rod is an inverted "L" structure, and the connecting rods are evenly distributed on the upper surface of the movable plate, with the baffle and the breathable mesh corresponding one-to-one.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: This auxiliary guiding LCD panel baking device adopts a novel structural design. By using fans evenly spaced on the surface of the outer plate, it can quickly dissipate heat from the LCD panel body after baking, improving work efficiency. Simultaneously, a moving structure for the placement plate is provided, allowing moisture on the LCD panel surface to quickly leave, facilitating the baking process. Furthermore, a moisture discharge structure is included to prevent moisture accumulation during baking, thus ensuring the baking results are not affected and guaranteeing a high yield rate. The specific details are as follows: In this auxiliary guide type LCD panel baking device, the workpiece to be processed is placed on the placement plate during use, and then the placement plate is pushed into the housing. After baking is completed, when the placement plate is removed, the fan will rotate. When the fan rotates, it plays a role in auxiliary heat dissipation, which facilitates the rapid dissipation of heat from the panel surface, thereby improving work efficiency. Furthermore, the fans are evenly distributed on the surface of the outer plate, which optimizes the heat dissipation effect. During the process of pulling out the placement plate, the lower block will slide on the surface of the long pin. After the placement plate is pushed into the housing, the lower block will stay stably on the long pin under the mutual attraction of the auxiliary magnets. That is, when the LCD panel is baked, the placement plate and the lower block will not move relative to the long pin, ensuring the stability of the LCD panel during processing. This auxiliary-guided LCD panel baking device operates by activating a motor on the outer wall of the housing. The motor rotates a connecting plate via a shaft. As the connecting plate rotates, the first magnet intermittently approaches the second magnet. When the first magnet approaches the second magnet, the upper connecting block, placement plate, lower connecting block, and long pin move outwards from the housing under the influence of repulsive magnetic forces. At this time, the long pin stretches the connecting spring. When the first magnet continues to rotate away from the second magnet, the long pin returns to its original position under the action of the connecting spring. This process repeats. When the motor is running, the placement plate, lower connecting block, and long pin move under the influence of the repulsive magnetic forces between the first and second magnets and the elastic force of the connecting spring. This keeps the LCD panel in motion, making it easier for moisture on the LCD panel surface to evaporate, thus improving work efficiency. (Magnetic forces at around 300°C will fail under high temperatures, but in LCD panel baking equipment, the temperature is generally 70°C to 90°C, so the magnetic forces of the first and second magnets are not affected.) Furthermore, when the lower connecting block and the placement plate move, the lower connecting block, under the mutual magnetic attraction between the auxiliary magnets, drives the long pin to move synchronously. When the long pin moves, it cooperates with the connecting spring to make reciprocating linear motion inside the inner tube, which optimizes the water removal effect of the LCD panel. In this auxiliary guide type LCD panel baking device, when the motor drives the rotating shaft to rotate, the rotating shaft also drives the cam to rotate synchronously. When the cam rotates, it intermittently pushes the movable plate. When the movable plate is pushed, it drives the connecting rod and the baffle to rise. At this time, the vent mesh is in a closed state. When the cam continues to rotate until it stops pushing the movable plate, the movable plate descends under its own gravity. At this time, the connecting rod and the baffle descend synchronously, and the vent mesh is opened. That is, when the long pin moves, the vent mesh is also in an intermittent opening and closing state, which facilitates the discharge of moisture and ensures the yield of high-quality products. Furthermore, during the movement of the movable plate, the limiting rod ensures that the movable plate moves only in the vertical direction, thus guaranteeing stability. At the same time, the breathable mesh is evenly distributed on the surface of the outer shell, optimizing the effect of water vapor discharge and improving work efficiency.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: By using the fan 10, heat can be dissipated from the LCD panel body after baking, improving work efficiency. Figures 1-4 as well as Figure 6 As shown: An auxiliary guiding type LCD panel baking device includes a housing 1 and a placement plate 2. An inner tube 4 is fixedly connected to the inner wall of the housing 1, and a long pin 5 is slidably arranged inside the inner tube 4. A motor 13 is bolted to the outer wall of the housing 1. A lower connecting block 3 is fixedly connected to the lower surface of the placement plate 2, and the lower connecting block 3 is slidably arranged on the surface of the long pin 5. A partition 25 is fixedly connected to the end of the long pin 5. Insertion slots are evenly spaced on the upper surface of the placement plate 2. An auxiliary guiding type LCD panel baking apparatus further includes: An outer plate 6 is fixedly connected to the outer wall of the outer shell 1, and a door panel that can slide up and down is slidably provided on the surface of the outer shell 1. A fan 10 and a rotating shaft 14 are rotatably provided on the upper surface of the outer plate 6. The rotating shaft 14 is fixedly connected to the output end of the motor 13, and a connecting plate 15 is fixedly connected to the end of the rotating shaft 14. A cam 16 is fixedly connected to the middle position of the rotating shaft 14. A limiting rod 18 is fixedly connected to the inner wall of the outer shell 1, and a movable plate 17 is slidably provided on the surface of the limiting rod 18. A connecting rod 21 and a baffle 22 are fixedly connected to the upper surface of the movable plate 17 and the baffle 22 is fixedly connected to the end of the connecting rod 21. The upper connecting block 23 is fixedly connected to the upper surface of the placement plate 2. The venting mesh 24 is fixedly connected to the inside of the outer shell 1. The inner wall of the lower connecting block 3 and the inner wall of the long pin 5 are both fixedly connected to auxiliary magnets 11, and the magnetic poles of adjacent auxiliary magnets 11 are opposite. The lower connecting blocks 3 are symmetrically distributed about the center of the placement plate 2.

[0020] The left and right sides of the placement plate 2 are fixedly connected with toothed blocks 7 at equal intervals. The outer plate 6 is rotatably provided with a connecting shaft 8, which passes through the interior of the outer plate 6. The surface of the connecting shaft 8 is fixedly connected with a gear 9, which meshes with the toothed blocks 7. The connecting shaft 8 is evenly distributed inside the outer plate 6, and a fan 10 is fixedly connected to the upper end of the connecting shaft 8.

[0021] During operation, the workpiece to be processed is inserted into the placement plate 2, and then the placement plate 2 is pushed into the interior of the outer casing 1. At this time, the lower connecting block 3 on the lower surface of the placement plate 2 will slide on the surface of the long pin 5. After the placement plate 2 is pushed into the interior of the outer casing 1, the lower connecting block 3 will be stably held on the surface of the long pin 5 under the action of the auxiliary magnet 11. That is, during the baking process of the outer casing 1, the lower connecting block 3 and the placement plate 2 will not slide on their own, ensuring stability. After baking, the door panel on the surface of the outer casing 1 is opened, and then the outer side of the outer casing 1 pulls the placement plate 2. During the pulling out process, the placement plate 2 drives the equally spaced toothed blocks 7 on the side to move synchronously. At this time, the toothed blocks 7 drive the connecting shaft 8 to rotate inside the outer plate 6 through the gear 9. When the connecting shaft 8 rotates, it drives the fan 10 to rotate synchronously. When the fan 10 rotates, it accelerates the airflow, thereby allowing the heat on the surface of the LCD panel to be carried away by the air. That is, the fan 10 plays a role in auxiliary heat dissipation and improves work efficiency. The fans 10 are evenly distributed on the upper surface of the outer plate 6, further optimizing the heat dissipation effect.

[0022] Example 2: Unlike Example 1, by using the first magnet 19, the second magnet 20, and the connecting spring 12, the long pin 5, the lower connecting block 3, and the placement plate 2 reciprocate linearly in the horizontal direction. The placement plate 2 drives the LCD panel to move synchronously, allowing the moisture on the surface of the LCD panel to evaporate more quickly. Figure 5 and Figure 6 As shown: A first magnet 19 is fixedly connected to the surface of the connecting plate 15, and a second magnet 20 is fixedly connected to the upper surface of the upper connecting block 23. The magnetic poles of the second magnet 20 and the first magnet 19 are the same at adjacent positions, and the first magnet 19 is distributed at equal angles on the surface of the connecting plate 15. A connecting spring 12 that plays an elastic reset role is fixedly connected to the surface of the long pin 5, and the other side of the connecting spring 12 is fixedly connected to the inner wall of the inner pipe 4.

[0023] During operation, the motor 13 on the outer wall of the outer casing 1 can be activated intermittently. When the motor 13 is working, it drives the connecting plate 15 to rotate via the rotating shaft 14. As the connecting plate 15 rotates, the first magnet 19 will intermittently approach the second magnet 20. When the first magnet 19 approaches the second magnet 20, the upper connecting block 23, the placement plate 2, the lower connecting block 3, and the long pin 5 move outward from the outer casing 1 under the action of mutual repulsive magnetic force. At this time, the long pin 5 will stretch the connecting spring 12. When the first magnet 19 continues to rotate away from the second magnet 20, the long pin 5 returns to its original position under the action of the connecting spring 12, and the above process is repeated. When the motor 13 is working, the placement plate 2, the lower connecting block 3, and the long pin 5 will reciprocate linearly under the action of the mutual repulsion magnetic force between the first magnet 19 and the second magnet 20 and the elastic force of the connecting spring 12. At this time, the LCD panel body is in a state of synchronous movement along with the placement plate 2, so that the moisture on the surface of the LCD panel is more easily evaporated, improving the working efficiency. The first magnet 19 is evenly distributed on the surface of the connecting plate 15, which optimizes the frequency of movement of the long pin 5 (while the lower connecting block 3 and the placement plate 2 move, the lower connecting block 3 drives the long pin 5 to move synchronously under the action of the mutual attraction magnetic force between the auxiliary magnets 11).

[0024] Example 3: Unlike Example 2, the ventilation mesh 24 is opened and closed intermittently through the cam 16, movable plate 17, connecting rod 21, and baffle 22. This allows the outer casing 1 to expel moisture during the baking process, thereby improving the yield rate of the LCD panel. Figures 7-10 As shown: The lower surface of the movable plate 17 is in contact with the end of the cam 16. The front view of the limiting rod 18 is an inverted "U" structure, and the limiting rod 18 is symmetrically distributed about the center of the movable plate 17. The front view of the connecting rod 21 is an inverted "L" structure, and the connecting rod 21 is evenly distributed on the upper surface of the movable plate 17. The baffle 22 corresponds to the ventilation net 24 one by one.

[0025] When motor 13 drives shaft 14 to rotate, shaft 14 also drives cam 16 to rotate synchronously. As cam 16 rotates, it intermittently pushes movable plate 17. When movable plate 17 is pushed, it causes connecting rod 21 and baffle 22 to rise, at which point the ventilation mesh 24 is closed. When cam 16 continues to rotate until it no longer pushes movable plate 17, movable plate 17 descends under its own weight. At this time, connecting rod 21 and baffle 22 descend synchronously, thus opening the ventilation mesh 24. When the long pin 5 moves, the breathable mesh 24 is also in an intermittent opening and closing state, which facilitates the discharge of water vapor and ensures the yield of high-quality products. During the movement of the movable plate 17, the limiting rod 18 makes the movable plate 17 move only in the vertical direction, ensuring stability. At the same time, the breathable mesh 24 is evenly distributed on the surface of the outer shell 1, which optimizes the effect of water vapor discharge and improves work efficiency. The limiting rod 18 has an inverted "U" shaped structure, which not only restricts the movement direction of the movable plate 17, but also restricts the movement distance of the movable plate 17.

[0026] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
