Technical Field

[0001] This invention relates to the field of liquid crystal display manufacturing equipment technology, and in particular to a liquid crystal display baking and curing apparatus. Background Technology

[0002] With the continuous development and progress of modern technology, the demand for electronic devices is constantly increasing. LCD screens are one of the important components of electronic devices. Therefore, the production and processing of LCD screens has become an indispensable step in the production of electronic devices. During the processing of LCD screens, adhesive needs to be applied to designated locations. After the adhesive is applied, it needs to be baked.

[0003] During the baking process, the LCD screen is usually placed directly on a conveyor and transported into the baking oven. Since both the LCD screen and the baking oven are in a fixed orientation, only one side of the LCD screen can be baked, which prolongs the time required for the LCD screen to dry completely and results in poor performance of the baking equipment. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a liquid crystal display baking and curing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A placement slot for placing the liquid crystal display screen is provided on the support swing plate. A swing transmission mechanism is also provided on the conveyor. When the support swing plate is conveyed with the conveyor, the swing transmission mechanism can drive the support swing plate to swing up and down reciprocally.

[0007] In some embodiments, an elastic support member is connected between the support base and the support swing plate. The elastic support member is used to provide elastic support for the support swing plate and keep the support swing plate in a horizontal state when there is no external force.

[0008] In some embodiments, the elastic support is a spring connected between the support base and the support swing plate. The support base has grooves spaced apart front to back, and a spring is provided in each of the two grooves. A baffle is spaced apart front to back on the lower side of the support swing plate, and the other end of the spring is connected to and abuts against the baffle.

[0009] In some embodiments, a hinge seat is provided on the lower side of the support swing plate, and a rotating shaft is provided on the hinge seat. The rotating shaft is located between the two springs and is rotatably mounted on the support seat.

[0010] In some embodiments, guide plates are provided on both the left and right sides of the conveyor.

[0011] In some embodiments, the swing transmission mechanism is disposed on the guide plate and located inside the housing.

[0012] In some embodiments, the swing transmission mechanism includes a vertical baffle plate disposed on the guide plate, a wave-shaped wavy groove disposed on the inner wall surface of the guide plate, the wave-shaped wavy groove being disposed along the conveying direction of the conveyor, and a guide post disposed on one side of the supporting swing plate, the guide post being able to enter the wave-shaped wavy groove when the supporting swing plate is conveyed with the conveyor.

[0013] In some embodiments, the two ends of the wave groove have a trumpet-shaped opening structure.

[0014] In some embodiments, a notch is provided at the outer edge of the support swing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When drying the LCD screen, it is placed in the placement slot of the support swing plate and then transported to the oven by the conveyor. While the support swing plate is being transported by the conveyor, it can be driven to swing up and down by the swing transmission mechanism, thereby baking the LCD screen from multiple angles, improving the baking rate, enhancing the baking effect, and further accelerating production efficiency and improving benefits.

[0021] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0022] like Figures 1-4 The illustrated liquid crystal display screen baking and curing apparatus includes a conveyor 1 and a baking and curing device mounted on the conveyor 1. The baking and curing device includes a housing 3 and a curing lamp 4 mounted inside the housing 3. A placement fixture 5 for placing the liquid crystal display screen is also provided on the conveyor 1. The placement fixture 5 includes a base plate 6 and a support base 7. A support swing plate 8 that can swing up and down is rotatably mounted on the support base 7. A placement groove 9 for placing the liquid crystal display screen is provided on the support swing plate 8. A swing transmission mechanism is also provided on the conveyor 1. When the support swing plate 8 is conveyed with the conveyor 1, the swing transmission mechanism can drive the support swing plate 8 to swing up and down reciprocally.

[0023] According to the above structure, when drying the LCD screen, it is placed in the placement slot 9 of the support swing plate 8, and then conveyed to the box 3 for baking by the conveyor 1. While the support swing plate 8 is being conveyed by the conveyor 1, it can be driven to swing up and down by the swing transmission mechanism, thereby baking the LCD screen from multiple angles, improving the baking rate, enhancing the baking effect, further accelerating production efficiency and improving benefits.

[0024] See Figure 2 , Figure 3 As shown, an elastic support member is connected between the support base 7 and the support swing plate 8. The elastic support member is used to provide elastic support for the support swing plate 8 and keep the support swing plate 8 in a horizontal state when there is no external force.

[0025] Furthermore, the elastic support is a spring 41 connected between the support base 7 and the support swing plate 8. The support base 7 has grooves 42 spaced apart front and back, and a spring 41 is provided in each of the two grooves 42. A baffle 43 is spaced apart front and back on the lower side of the support swing plate 8, and the other end of the spring 41 is connected to and abuts against the baffle 43. A hinge seat 31 is provided on the lower side of the support swing plate 8, and a rotating shaft 32 is provided on the hinge seat 31. The rotating shaft 32 is located between the two springs 41 and is rotatably mounted on the support base 7.

[0026] Thus, the springs 41 set at the front and rear can support the swing plate 43, so that when the swing plate 8 is separated from the swing transmission mechanism, it can maintain a relatively horizontal state. At the same time, it can make the swing plate 8 and the swing transmission mechanism connect better and more stably.

[0027] See Figure 1 As shown, guide plates 51 are provided on both the left and right sides of the conveyor 1, which can limit and guide the base plate 6, so that the placement fixture 5 can be conveyed more stably.

[0028] See Figure 2 , Figure 4 As shown, the swing transmission mechanism is mounted on the guide plate 51 and located inside the housing 3.

[0029] Furthermore, the swing transmission mechanism includes a vertical baffle 71 disposed on the guide plate 51, and a wave-shaped wavy groove 72 disposed on the inner wall surface of the guide plate 51. The wave-shaped groove 72 is disposed along the conveying direction of the conveyor 1. A guide post 73 is disposed on one side of the supporting swing plate 8. When the supporting swing plate 8 is conveyed with the conveyor 1, the guide post 73 can enter the wave-shaped groove 72. When the guide post 73 enters the wave-shaped groove 72, the guide post 73 can swing up and down with the wave-shaped groove 72, thereby realizing the up and down swing of the supporting swing plate 8.

[0030] In order to ensure that the guide post 73 can accurately enter the wave groove 72, the two ends of the wave groove 72 are flared openings.

[0031] To facilitate the removal of the LCD screen from the placement slot 9, a notch 91 is provided on the outer edge of the support swing plate 8.
