Description

Technical Field

[0001] The invention relates to the field of automation equipment, and in particular to a large-size panel degassing bearing platform. Background Art

[0002] In the field of flat panel display device production equipment, it is often involved in the attachment of various optical film materials, such as polarizer attachment. After the optical film body is attached to the screen substrate, it is necessary to remove the bubbles generated when the film body and the substrate are attached by various means to ensure the attachment quality. There are many commonly used degassing methods, such as improving the film material attachment method, using the edge-to-edge roller method, and rolling the film material while attaching to reduce the generation of bubbles. This mechanical degassing method can have a certain effect. However, for large-sized panels, due to the large area, the degassing method by rolling is less effective, and the panel is very easy to break due to rolling. Therefore, it is necessary to adopt an auxiliary degassing method, such as a vacuum environment or a pressurized environment. The vacuum environment is to place the panel to be degassed in a strong pressure environment, and adjust the air pressure around the panel to reduce it. The air pressure is lowered to be less than the air pressure in the bubble, so that the gas in the bubble is automatically squeezed out from between the panel and the film material to achieve the degassing effect; the pressurized environment is the opposite. The panel is placed in a strong pressure environment, and the film body is squeezed by external pressure to achieve the degassing effect.

[0003] Due to the long degassing time (holding time after partial lamination: 70-180S; holding time after full lamination: 5-10Min), the traditional method of placing all materials in the degassing chamber and then degassing has a long degassing waiting time. The subsequent process needs to wait until the degassing is completed before it can be carried out, and the loading and unloading before and after degassing also take a long time, resulting in low overall degassing efficiency. Therefore, for the degassing of large-size panels, the degassing method of feeding a single panel separately is generally adopted due to the influence of the panel size; that is, through an independent degassing chamber, loading, degassing and unloading actions are performed one by one. While one degassing chamber is degassing, the other degassing chamber is loading and unloading, making full use of the loading, degassing and unloading time, thereby improving the degassing efficiency of the whole machine. The following technical problems need to be solved for the independent degassing of large-size panels: 1. The formation and separation of the sealed chamber involved in the loading and unloading process of the independent degassing cavity; 2. The load-bearing and limiting of the material tray during the formation and separation of the sealed chamber to ensure the stability and accuracy of the action when the sealed chamber is formed; 3. During the formation of the sealed chamber, the material tray is evenly loaded and lifted to complete the closure of the chamber. Summary of the invention

[0014] The beneficial effects of the present invention are:

[0015] The present invention improves and innovates the defects and steps existing in the prior art, designs an independent degassing chamber structure, utilizes the linear sliding of the material tray to complete the automatic loading, feeding and discharging actions, and completes the uniform lifting, automatic support and limiting of the supporting material tray through synchronous rotation, realizing a large-size panel degassing supporting platform with automatic opening and closing linkage of an independent sealed chamber.

[0016] The present invention is aimed at the pressurized degassing process of large-size panels, and adopts an independent degassing chamber structure design. The degassing bearing platform is arranged in an upper and lower interval manner in the pressurized degassing machine, and an independent degassing space is formed between the upper and lower degassing bearing platforms. The present invention realizes the loading, feeding and unloading actions of the panel by driving the linear sliding of the material tray by the driving component. After the material tray slides into the degassing space, the material tray is supported and lifted from below by the bearing lifting component to push the material tray up. At the same time, a sealing ring is embedded in the storage space that is recessed inwardly around the circumference of the material tray body. The material tray rises, so that the sealing ring is tightly attached to the bottom of the upper bearing platform, so that the space between the upper and lower degassing bearing platforms is closed into a sealed chamber. In addition, the present invention is provided with side support plates and support blocks on the side of the material tray, and a plurality of limit columns are vertically provided on the inner wall of the side support plates, and the limit columns extend horizontally inwardly, and a step support surface is provided on the inner side of the top of the support block, and the height of the step surface is lower than the height of the limit column.

When the material tray is lifted to form a closed chamber, the bottom of the material tray presses the spring upward against the support plate. After moving to the step surface, the spring elastic force presses the support plate inward to the bottom of the material tray, and the material tray is supported by the step surface. At the same time, the limit columns extending horizontally on the inner side of the side support plates on both sides of the material tray press against the side walls of the material tray from both sides, realizing the guide limit during the rising process of the material tray, effectively ensuring the accuracy of the moving position during the rising process of the material tray, and ensuring that the sealed chamber is formed stably and accurately. At the same time, a plurality of air holes are also provided on the inner side of the storage space along the upper edge of the material tray body of the present invention. After the sealing ring forms a closed chamber, the pressurization action of the closed chamber is completed through the air holes.

[0017] In particular, the load-bearing lifting assembly of the present invention realizes the synchronous linkage of multiple support rollers through a multi-link structure, and adopts a support convex strip structure arranged in the circumferential direction of the support roller. When multiple support rollers rotate synchronously, the outer diameter of the support convex strip is larger than the support roller. By converting the rotational motion into the linear motion of the support convex strip to push the material tray, the material tray is automatically and synchronously uniformly loaded and pushed up. The load-bearing lifting assembly of the present invention is ingeniously designed with a support roller whose outer wall is a strip-shaped convex structure arranged at intervals, wherein a support convex strip with an outer diameter larger than the others is arranged between the strip-shaped convex strips, and the outer wall of the support convex strip is a curved surface structure; through this structural design, when the support roller rotates as a whole, the support convex strip changes its external height in the vertical direction as the support roller rotates. At the same time, the load-bearing lifting assembly adopts a parallel and spaced arrangement structure of multiple support rollers, which can be rotatably connected to the support. The cylinder drives the connecting rod to drive the multiple push rods to rotate synchronously, and the push rod drives the multiple support rollers to be synchronously linked, thereby realizing the function of using the support convex strip to carry the material tray above the support roller and push up synchronously. This structural design converts rotational motion into linear motion in the vertical direction, thereby achieving the function of bearing and lifting the material tray. The transmission is smooth and the synchronization is good. The spaced layout design of the transmission rollers effectively ensures the uniformity of the force on the material tray during the movement. BRIEF DESCRIPTION OF THE DRAWINGS
