Description

Technical Field

[0001] The invention relates to the technical field of LCD liquid crystal panel processing, in particular to a baking and curing device for LCD liquid crystal panel processing. Background Art

[0002] LCD panels are widely used in the electronics field, such as mobile phones, digital cameras and camcorders, and can also be used as raw materials for car navigation systems and control screens. They have the advantages of low power consumption and low cost, and they have a long service life. When processing LCD panels, they need to be baked. Baking LCD panels can improve the quality and performance of LCD panels and optimize the display effect of liquid crystal. In this operation, baking and curing equipment is needed. When the baking and curing equipment is working, it is equipped with ultraviolet (UV) light source, which can evenly irradiate the coating on the LCD panel to achieve baking. During the processing, the LCD panel needs to be baked at multiple angles to achieve uniform processing of the LCD panel. If the LCD panel is not baked evenly, it will lead to uneven brightness. At the same time, when it is used, it will also lead to reduced contrast, which will affect the customer's experience. In order to overcome the above defects, prior art 1 (application number CN201310408386.5, Chinese patent application date 2013-09-09) is a baking device for a liquid crystal alignment film, which is provided with a baffle. The baffle can block the airflow flowing to the glass substrate with the alignment film during the baking process, thereby preventing the airflow from affecting the heat distribution and temperature distribution. During the baking process, a balanced temperature can be maintained on the entire glass substrate to prevent the alignment film from being heated unevenly, thereby solving the problem of color unevenness, so that the final display panel has uniform optical properties and the display image is uniform; Prior art 2 (Chinese patent with application number CN202311766765.1 and application date 2023-12-21) is a high-temperature infrared baking furnace for liquid crystal glass, which uses the arrangement of infrared heaters, first infrared coatings and other structures, and thus uses far-infrared radiation technology to independently heat and control each layer of glass, making the glass temperature more uniform; Prior art 3 (Chinese patent with application number CN202111521940.1 and application date 2021-12-14) A contact baking oven for liquid crystal display substrates, which can not only realize the autonomous lifting and transfer of glass substrates with a high degree of automation, but also has uniform heating, stable baking effect, and strict sealing of the baking cavity; After processing, the air temperature inside the device is high, and the internal temperature needs to be quickly processed. However, the device in the above application does not have a structure for quickly processing hot air, that is, there is no good structure for utilizing waste heat, resulting in energy waste.

[0004] The purpose of the present invention is to provide a baking and curing device for LCD liquid crystal panel processing to solve the problem of the structure without rapid hot air processing proposed in the above background technology, that is, the structure without good waste heat utilization, resulting in energy waste.

[0005] To achieve the above object, the present invention provides the following technical solution: a baking and curing device for processing LCD liquid crystal panels, comprising a housing and a motor, wherein the surface of the housing is movably connected to a door panel via an electric slide rail, and the upper surface of the housing is fixedly connected to an upper plate, and the interior of the housing is movably connected to a movable plate via an electric slide rail; The motor is bolted to the lower surface of the movable plate, and the output end of the motor is fixedly connected to a connecting shaft, and the surface of the connecting shaft is fixedly connected to a working plate; The working plate is provided with a rotating shaft for rotation inside, and a clamping plate is fixedly connected to the upper surface of the rotating shaft; Also includes: A rack, the rack is fixedly connected to the housing via an external auxiliary rod, and a rotating assembly is disposed inside the housing; An external pipe is fixedly connected to the inside of the upper plate, and a first air suction component and a second air suction component are arranged on the lower surface of the upper plate, and the first air suction component includes a No. 1 head movably arranged on the lower surface of the upper plate, and the second air suction component includes a No. 2 head movably arranged on the surface of the upper plate.

[0006] Preferably, the rotating assembly includes a gear fixedly connected to the lower surface of the rotating shaft, the gear and the rack are meshingly connected, and the rotating shaft is distributed at equal angles on the surface of the working plate.

[0007] Preferably, the rack is an arc-shaped structure, and the clamping plate is an inverted "L" structure when viewed from the left.

[0008] Preferably, the first air suction component further comprises a connecting plate fixedly connected to the upper end surface of the connecting shaft, and the surface of the connecting plate is fixedly connected to the first magnets, and the first magnets are distributed at equal angles on the surface of the connecting plate.

[0009] Preferably, the first air suction component also includes a lower connecting plate fixedly connected to the lower surface of the upper plate, and a long pin is rotatably arranged inside the lower connecting plate, and a pipe sleeve is fixedly connected to the surface of the long pin, and a limiting rod is fixedly connected to the inner wall of the lower connecting plate.

[0010] Preferably, the No. 1 head is fixedly connected to the lower surface of the pipe sleeve, and the No. 1 head is symmetrically distributed about the center of the upper plate, and the surface of the pipe sleeve is fixedly connected to the second magnet.

[0011] Preferably, the magnetic poles on the surface of the second magnet are opposite to the magnetic poles on the surface of the first magnet, a torsion spring having an elastic reset function is fixedly connected to the surface of the long pin, and the other side of the torsion spring is fixedly connected to the inner wall of the lower connecting plate.

[0012] Preferably, the second air suction assembly also includes an auxiliary plate fixedly connected to the lower surface of the upper plate, and an inner rod is rotatably arranged inside the auxiliary plate, and a force-bearing plate is fixedly connected to the surface of the inner rod, and the lower surface of the force-bearing plate is fixedly connected to the No. 2 head, and the No. 2 head is symmetrically distributed about the center of the upper plate.

[0013] Preferably, the end of the connecting shaft is fixedly connected to a top plate, and both sides of the top plate are inclined, and the surface of the force-bearing plate is fixedly connected to an outer plate, and both sides of the outer plate are inclined.

[0014] Preferably, the surface of the No. 2 head and the surface of the No. 1 head are both fixedly connected with connecting pipes, and the ends of the connecting pipes are connected to the external pipes through external hoses.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the baking and curing equipment for LCD liquid crystal panel processing adopts a new structural design. By setting a rotating component, the working plate can drive the clamping plate to rotate, so that the liquid crystal panel is evenly baked. At the same time, the rotating shaft and the clamping plate rotate under the action of the rack and the gear, that is, the clamping plate self-rotates, which further optimizes the effect of uniform baking. When the shell stops heating, the motor continues to work. At this time, the No. 1 head is in a swinging state, and then the adsorption range of the No. 1 head is wider, the working efficiency is higher, and the waste heat can be better utilized. At the same time, when the workpiece needs to be taken out, the movable plate is driven to move outward by the electric slide rail. In this process, the No. 2 head is also in a swinging state. At this time, the working range of the No. 2 head is also increased, and the effect of waste heat utilization is optimized. The specific contents are as follows: The baking and curing equipment for LCD panel processing, when working, fixes the workpiece on the clamping plate, drives the movable plate into the shell through the electric slide rail, and then closes the door plate through the electric slide rail. At this time, the shell starts to work, and the motor starts at the same time. When the motor is working, the connecting shaft and the working plate are in a rotating state, and the workpiece can be better heated at this time, so that it can be processed more evenly; Furthermore, when the working plate rotates, the rotating shaft and the gear rotate synchronously, and when the gear and the rack are meshed, the rotating shaft and the clamping plate rotate by themselves, and then the clamping plate is in a self-rotating state, that is, each surface of the liquid crystal panel can be evenly heated, so that the baking is more uniform; Furthermore, when the movable plate enters the housing, the distance is controlled so that the gear can mesh with the rack when rotating, thus ensuring the working stability of the gear and rack; The baking and curing equipment for LCD panel processing starts the No. 1 head after the processing is completed and the shell stops baking. The No. 1 head sends the hot air through the connecting pipe and the external pipe to the required position, realizing the waste heat utilization. At this time, the motor continues to rotate, and then the connecting shaft and the connecting plate continue to rotate. At this time, the first magnet will intermittently approach the second magnet, and then the pipe sleeve and the No. 1 head drive the long pin to swing back and forth inside the lower connecting plate under the action of the mutually repulsive magnetic force and the torsion spring. At this time, the No. 1 head has a wider adsorption range, higher working efficiency, and can better utilize the waste heat. Furthermore, during the rotation of the sleeve, the limit rod limits the rotation angle of the sleeve, and excessive rotation will not occur, thus ensuring the working stability of the sleeve and the No. 1 head; (3) In the baking and curing equipment for processing LCD panels, when it is necessary to remove the workpiece, the movable plate is driven to move outward by the electric slide rail. During this process, the top plate moves synchronously. When the top plate moves to contact the outer plate, the outer plate and the force-bearing plate are pushed. At this time, the force-bearing plate drives the No. 2 head and the inner rod to rotate inside the auxiliary plate. When the top plate continues to move until it does not contact the outer plate, the force-bearing plate and the No. 2 head rotate under the action of their own gravity, and then the No. 2 head is also in a swinging state. At this time, the working range of the No. 2 head is also increased, optimizing the effect of waste heat utilization. BRIEF DESCRIPTION OF THE DRAWINGS

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 a rotating assembly, the clamping plate 8 and the working plate 7 can be rotated during the processing of the LCD panel, so that the LCD panel can be baked more evenly. Figure 1-Figure 4 As shown: It comprises a housing 1 and a motor 5, wherein the surface of the housing 1 is movably connected to a door panel 3 via an electric slide rail, an upper panel 2 is fixedly connected to the upper surface of the housing 1, and a movable panel 4 is movably connected to the interior of the housing 1 via an electric slide rail; The motor 5 is bolted to the lower surface of the movable plate 4, and the output end of the motor 5 is fixedly connected to the connecting shaft 6, and the surface of the connecting shaft 6 is fixedly connected to the working plate 7, the working plate 7 is rotatably provided with a rotating shaft 10, and the upper surface of the rotating shaft 10 is fixedly connected to the clamping plate 8; Also includes: The rack 9 is fixedly connected to the outer shell 1 through an external auxiliary rod, and a rotating component is arranged inside the outer shell 1, an external pipe 24, and the external pipe 24 is fixedly connected to the inside of the upper plate 2, and a first suction component and a second suction component are arranged on the lower surface of the upper plate 2, and the first suction component includes a No. 1 head 18 movably arranged on the lower surface of the upper plate 2, and the second suction component includes a No. 2 head 22 movably arranged on the surface of the upper plate 2.

[0020] The rotating assembly includes a gear 11 fixedly connected to the lower surface of the rotating shaft 10, and the gear 11 and the rack 9 are meshingly connected, and the rotating shaft 10 is distributed at equal angles on the surface of the working plate 7, the rack 9 is an arc structure, and the left view of the clamping plate 8 is an inverted "L" structure.

[0021] During operation, the workpiece is fixed on the clamping plate 8, and the movable plate 4 is driven into the outer shell 1 by the electric slide rail, and then the door panel 3 is closed by the electric slide rail. At this time, the outer shell 1 starts to work, and the motor 5 is started at the same time. When the motor 5 is working, the connecting shaft 6 and the working plate 7 will be in a rotating state. At this time, the workpiece can be better heated so that it can be processed more evenly. When the working plate 7 rotates, it drives the rotating shaft 10 and the gear 11 to rotate synchronously. When the gear 11 and the rack 9 are engaged, the rotating shaft 10 and the clamping plate 8 will rotate by themselves, and then the clamping plate 8 will be in a self-rotating state, that is, each surface of the liquid crystal panel can be evenly heated, so that the baking result is more in line with expectations.

[0022] Embodiment 2: Different from Embodiment 1, the heat can be better utilized after the shell 1 is baked by setting the first air intake assembly. Figure 5-Figure 8 As shown: The first air suction component also includes a connecting plate 12 fixedly connected to the upper end surface of the connecting shaft 6 , and the surface of the connecting plate 12 is fixedly connected to the first magnets 13 , and the first magnets 13 are distributed at equal angles on the surface of the connecting plate 12 .

[0023] The first air suction component also includes a lower connecting plate 14 fixedly connected to the lower surface of the upper plate 2, and a long pin 15 is rotatably arranged inside the lower connecting plate 14, and a pipe sleeve 16 is fixedly connected to the surface of the long pin 15, and a limiting rod 25 is fixedly connected to the inner wall of the lower connecting plate 14.

[0024] A head No. 18 is fixedly connected to the lower surface of the pipe sleeve 16, and the head No. 18 is symmetrically distributed about the center of the upper plate 2, and a second magnet 17 is fixedly connected to the surface of the pipe sleeve 16, and the magnetic poles on the surface of the second magnet 17 are opposite to the magnetic poles on the surface of the first magnet 13, and a torsion spring 26 that plays an elastic reset role is fixedly connected to the surface of the long pin 15, and the other side of the torsion spring 26 is fixedly connected to the inner wall of the lower connecting plate 14.

[0025] After the processing is completed, when the shell 1 stops baking, the No. 1 head 18 is started, and the No. 1 head 18 sends the hot air through the connecting pipe 23 and the external pipe 24, and transports the hot air to the required position. At this time, the motor 5 continues to rotate, and then the connecting shaft 6 and the connecting plate 12 continue to rotate. At this time, the first magnet 13 will intermittently approach the second magnet 17. When the first magnet 13 approaches the second magnet 17, the sleeve 16 rotates toward the position of the connecting plate 12 under the action of the mutual magnetic force. The sleeve 16 drives the long pin 15 to rotate inside the lower connecting plate 14. At this time, the torsion spring 26 is stretched by the long pin 15, and when the first magnet 13 rotates to be away from the second magnet 17, the sleeve 16 and the long pin 15 rotate under the action of the torsion spring 26. When the connecting plate 12 rotates, the first magnet 13 will intermittently approach the second magnet 17, and repeat the above process. The sleeve 16 and the No. 1 head 18 drive the long pin 15 to swing back and forth inside the lower connecting plate 14 under the action of the mutually repulsive magnetic force and the torsion spring 26. At this time, the adsorption range of the No. 1 head 18 is wider, the working efficiency is higher, and the waste heat can be better utilized. During the rotation of the sleeve 16, the limit rod 25 limits the rotation angle of the sleeve 16, and excessive rotation will not occur, thereby ensuring the working stability of the sleeve 16 and the No. 1 head 18.

[0026] Embodiment 3: Different from Embodiment 2, the second suction assembly can be used to suck away the hot air during the process of removing the workpiece, and the second head 22 can also be in a swinging state, thereby optimizing the effect of waste heat utilization. Fig. 9 and Fig.10 As shown: The second air suction component also includes an auxiliary plate 19 fixedly connected to the lower surface of the upper plate 2, and an inner rod 20 is rotatably arranged inside the auxiliary plate 19, and a force-bearing plate 21 is fixedly connected to the surface of the inner rod 20, and a second head 22 is fixedly connected to the lower surface of the force-bearing plate 21, and the second head 22 is symmetrically distributed about the center of the upper plate 2.

[0027] The end of the connecting shaft 6 is fixedly connected to a top plate 27, and both sides of the top plate 27 are inclined. The surface of the force-bearing plate 21 is fixedly connected to an outer plate 28, and both sides of the outer plate 28 are inclined. The surface of the No. 2 head 22 and the surface of the No. 1 head 18 are fixedly connected to a connecting pipe 23, and the end of the connecting pipe 23 is connected to an external hose and an external pipe 24.

[0028] When it is necessary to take out the workpiece, the movable plate 4 is driven by the electric slide rail to move to the outside of the shell 1, and the door panel 3 is raised at the same time. During the outward movement of the movable plate 4, the top plate 27 moves synchronously. When the top plate 27 moves to contact the outer plate 28, the outer plate 28 and the force-bearing plate 21 are pushed. At this time, the force-bearing plate 21 drives the No. 2 head 22 and the inner rod 20 to rotate inside the auxiliary plate 19. When the top plate 27 continues to move until it does not contact the outer plate 28, the force-bearing plate 21 and the No. 2 head 22 rotate under the action of their own gravity, and then the No. 2 head 22 is also in a swinging state. At this time, the working range of the No. 2 head 22 is also increased, which optimizes the effect of waste heat utilization. When it is necessary to process again, the workpiece can be docked on the clamping plate 8. At the same time, when the movable plate 4 enters the inside of the shell 1, the distance is controlled so that the gear 11 can mesh with the rack 9 when it rotates, thereby ensuring the working stability of the gear 11 and the rack 9.

[0029] 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.
