Description

Technical Field

[0001] The invention relates to the technical field of LCD liquid crystal panel processing, in particular to an auxiliary guide type LCD liquid crystal panel baking device. Background Art

[0002] LCD panel is a display device with excellent color expression and high resolution. It can be used in home TV, office projection display, and indoor and outdoor advertising. During the processing of LCD panels, they need to be baked. When baking LCD panels, professional baking equipment is needed. When baking LCD panels, moisture and impurities inside the panels can be removed, which improves the quality rate and reduces the failure rate. During the baking process, after the water evaporates, it will condense inside the oven. If the oven continues to work, it will affect the subsequent baking process, which may cause uneven heating of the panel body. The heat inside the oven and the smoke generated during the heating process are difficult to discharge, which will extend the baking time. This will not only increase production costs, but also affect production efficiency. In order to overcome the above defects, prior art 1 (Chinese patent with application number CN202020138931.9 and application date 2020-01-20) is a baking oven, which includes a support frame and a first support block and a second support block each provided with a slide groove, and a heating plate is provided under the support frame. The baking oven has a simple structure, which can not only bake the baked goods, but also collect and process the high-temperature water vapor during baking, which is more efficient; Prior art 2 (Chinese patent with application number CN201710166919.1 and application date 2017-03-20) is a color film substrate baking oven, which speeds up the removal of smoke in the baking oven, reduces the pollution of the color film substrate caused by smoke condensation, and ensures the quality of the color film substrate; After the heating is completed, the 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 heat dissipation during use, and the working efficiency is low.

[0003] In view of the above problems, it is urgent to carry out innovative design based on the original LCD liquid crystal panel baking device. Summary of the invention

[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 positions of the adjacent auxiliary magnets are opposite, and the lower connecting block is symmetrically distributed about the center of the placement plate.

[0007] Preferably, the surfaces of the left and right sides of the placement plate are fixedly connected with gear blocks at equal intervals, and a connecting shaft is rotatably provided inside the external plate, and the connecting shaft runs through the inside of the external plate.

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

[0009] Preferably, the connecting shafts are distributed at equal intervals inside the external plate, and the fan is fixedly connected to the upper end of the connecting shaft.

[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 pole as the first magnet at adjacent positions, and the first magnets are distributed at equal angles on the surface of the connecting plate.

[0012] Preferably, a connection spring having an elastic reset function is fixedly connected to the surface of the long pin, and the other side of the connection spring is fixedly connected to the inner wall of the inner pipe.

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

[0014] Preferably, the connecting rods are viewed from the front as an inverted "L" structure, and the connecting rods are distributed at equal intervals on the upper surface of the movable plate, and the baffles correspond to the breathable nets one by one.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the auxiliary guide type LCD liquid crystal panel baking device adopts a new structural design, and through the fans arranged at equal intervals on the surface of the external board, the LCD panel body can be quickly cooled after baking, thereby improving the working efficiency. At the same time, a moving structure of the placement plate is also provided, so that the water vapor on the surface of the LCD panel quickly leaves the surface of the LCD panel, which is convenient for baking the LCD panel. In addition, a water vapor exhaust structure is also provided, so that the water vapor in the baking process is not accumulated, and thus the baking result of the LCD panel is not affected, thereby ensuring the quality rate. The specific contents are as follows: When the auxiliary guide type LCD panel baking device is used, the workpiece to be processed is placed on the placement plate, and then the placement plate is pushed into the inner part of the housing. After the baking is completed, when the placement plate is taken out, the fan will rotate. When the fan rotates, it plays a role of auxiliary heat dissipation, which facilitates the rapid volatilization of the heat on the panel surface, thereby improving the work efficiency. Furthermore, the fans are evenly spaced on the surface of the external board, which optimizes the heat dissipation effect. In the process of pulling out the placement board, the lower connection block slides on the surface of the long pin. After the placement board is pushed into the housing, the lower connection block stays stably on the long pin under the mutual magnetic force of the auxiliary magnets. That is, when the LCD panel is baked, the placement board and the lower connection block will not move relative to the long pin, thereby ensuring the stability of the LCD panel during processing. The auxiliary guide type LCD liquid crystal panel baking device starts the motor on the outer wall of the shell when working. When the motor works, the connecting plate is driven to rotate through the rotating shaft. When the connecting plate rotates, the first magnet will intermittently approach the second magnet. When the first magnet approaches the second magnet, the upper connecting block, the placement plate, the lower connecting block and the long pin move toward the outer side of the shell under the action of the mutually repulsive magnetic force. 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. The above process is repeated. When the motor works, the placement plate, the lower connecting block and the long pin move under the action of the mutually repulsive magnetic force between the first magnet and the second magnet and the elastic force of the connecting spring. At this time, the LCD panel body is in a moving state, and the moisture on the surface of the LCD panel is more easily evaporated, thereby improving the working efficiency (the magnetic force is about 300 degrees, which will fail under the influence of high temperature, while in the LCD panel baking device, it is generally 70 degrees to 90 degrees, so the magnetic force of the first magnet and the second magnet will not be affected); Furthermore, when the lower connecting block and the placement plate move, the lower connecting block drives the long pin to move synchronously under the action of the mutual magnetic force between the auxiliary magnets, and when the long pin moves, it cooperates with the connecting spring to make reciprocating linear motion inside the inner tube, thereby optimizing the dewatering effect of the LCD panel; In the 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, and when the cam rotates, it will intermittently push the movable plate. When the movable plate is pushed, the movable plate drives the connecting rod and the baffle to rise, and the air-permeable net is in a closed state at this time. When the cam continues to rotate until it does not push the movable plate, the movable plate falls under its own gravity, and the connecting rod and the baffle fall synchronously at this time, and then the air-permeable net is opened, that is, when the long pin moves, the air-permeable net is also in an intermittent opening and closing state, which is convenient for the discharge of water vapor and ensures the quality rate. Furthermore, during the movement of the movable plate, the limit rod enables the movable plate to move only in the vertical direction, thereby ensuring stability. At the same time, the breathable mesh is evenly distributed on the surface of the shell, thereby optimizing the effect of water vapor discharge and improving work efficiency.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: By setting the fan 10, the LCD panel body can be cooled after baking, thereby improving the working efficiency. Figure 1-Figure 4 as well as Figure 6 As shown: An auxiliary guide type LCD liquid crystal panel baking device comprises a shell 1 and a placement plate 2, an inner tube 4 is fixedly connected to the inner wall of the shell 1, and a long pin 5 is slidably arranged inside the inner tube 4, and a motor 13 is bolted to the outer wall of the shell 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, and a partition 25 is fixedly connected to the end of the long pin 5, and insertion grooves are evenly spaced on the upper surface of the placement plate 2; An auxiliary guide type LCD liquid crystal panel baking device also includes: An external plate 6, the external plate 6 is fixedly connected to the outer wall of the housing 1, and a door plate that can move up and down can be slidably arranged on the surface of the housing 1, and a fan 10 is rotatably arranged on the upper surface of the external plate 6, and a rotating shaft 14, the rotating shaft 14 is fixedly connected to the output end of the motor 13, and the end of the rotating shaft 14 is fixedly connected to the connecting plate 15, and the middle position of the rotating shaft 14 is fixedly connected to the cam 16; A limit rod 18, the limit rod 18 is fixedly connected to the inner wall of the housing 1, and a movable plate 17 is slidably provided on the surface of the limit rod 18, and 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 air permeable net 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 fixedly connected with auxiliary magnets 11, and the magnetic poles of adjacent positions of adjacent auxiliary magnets 11 are opposite, and the lower connecting block 3 is symmetrically distributed about the center of the placement plate 2.

[0020] The surfaces of the left and right sides of the placement plate 2 are fixedly connected with tooth blocks 7 at even intervals, a connecting shaft 8 is rotatably arranged inside the external plate 6, and the connecting shaft 8 runs through the inside of the external plate 6, a gear 9 is fixedly connected to the surface of the connecting shaft 8, and the gear 9 is meshed with the tooth blocks 7, the connecting shaft 8 is evenly distributed inside the external 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 shell 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 shell 1, the lower connecting block 3 will stably stay on the surface of the long pin 5 under the action of the auxiliary magnet 11, that is, during the baking process of the shell 1, the lower connecting block 3 and the placement plate 2 will not slide by themselves, thereby ensuring stability. At the same time, after the baking is completed, the door panel on the surface of the shell 1 is opened, and then the placement plate 2 is pulled from the outside of the shell 1. During the pulling out process of the placement plate 2, the placement plate 2 drives the tooth blocks 7 with equal spacing on the side to move synchronously. At this time, the tooth block 7 drives the connecting shaft 8 to rotate inside the external 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, the airflow is accelerated, so that the heat on the surface of the LCD panel is taken away by the air, that is, the fan 10 plays a role in auxiliary heat dissipation, thereby improving the working efficiency. The fan 10 is evenly spaced and distributed on the upper surface of the external plate 6, further optimizing the heat dissipation effect.

[0022] Embodiment 2: Different from Embodiment 1, by providing 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 make reciprocating linear motion in the horizontal direction, and the placement plate 2 drives the LCD panel to move synchronously. At this time, the moisture on the surface of the LCD panel can be evaporated faster, such as Figure 5 and Figure 6 As shown: A first magnet 19 is fixedly connected to the surface of the connecting plate 15, a second magnet 20 is fixedly connected to the upper surface of the upper connecting block 23, the second magnet 20 has the same magnetic pole as the first magnet 19 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 which 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 shell 1 can be started intermittently. When the motor 13 is working, the connecting plate 15 is driven to rotate through the rotating shaft 14. When 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 toward the outside of the shell 1 under the action of the mutually 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 make reciprocating linear motion under the action of the mutual repulsive 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 moving state synchronously with the placement plate 2, so that the moisture on the surface of the LCD panel is more easily evaporated, thereby improving the working efficiency. The first magnets 19 are evenly spaced on the surface of the connecting plate 15, which optimizes the movement frequency of the long pin 5 (and when 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 attractive magnetic force between the auxiliary magnets 11).

[0024] Embodiment 3: Different from Embodiment 2, the cam 16, the movable plate 17, the connecting rod 21 and the baffle 22 are provided to make the air permeable net 24 open and close intermittently, that is, the housing 1 can discharge the water vapor during the baking process, thereby improving the quality rate of the LCD panel. Figure 7-Figure 10 As shown: The lower surface of the movable plate 17 is fitted with the end of the cam 16, the limit rod 18 is an inverted "U" structure when viewed from the front, and the limit rod 18 is symmetrically distributed about the center of the movable plate 17, the connecting rod 21 is an inverted "L" structure when viewed from the front, and the connecting rods 21 are evenly spaced on the upper surface of the movable plate 17, and the baffle 22 corresponds to the breathable net 24 one by one.

[0025] When the motor 13 drives the rotating shaft 14 to rotate, the rotating shaft 14 also drives the cam 16 to rotate synchronously. When the cam 16 rotates, it will intermittently push the movable plate 17. When the movable plate 17 is pushed, the movable plate 17 drives the connecting rod 21 and the baffle 22 to rise. At this time, the air-permeable net 24 is in a closed state. When the cam 16 continues to rotate until it stops pushing the movable plate 17, the movable plate 17 descends under its own gravity. At this time, the connecting rod 21 and the baffle 22 descend synchronously, and then the air-permeable net 24 is opened. When the long pin 5 moves, the breathable net 24 is also in an intermittent opening and closing state, which is convenient for the discharge of water vapor and ensures the quality rate. 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 net 24 is evenly spaced on the surface of the outer shell 1, which optimizes the effect of water vapor discharge and improves work efficiency. The limiting rod 18 is an inverted "U"-shaped structure, which not only limits the moving direction of the movable plate 17, but also limits the moving distance of the movable plate 17.

[0026] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
