AI Technical Summary
When traditional AT protective bearing platforms are used to combine the screen and backlight, the adhesive strength between the tape at the edge of the backlight and the screen is not activated, leading to defects such as back-end delamination, which affects product yield and makes it difficult to adapt to different product specifications and the four corners of the protective screen.
The platform is equipped with inclined and straight sliding grooves, movable upper and lower rubber-coated buffer blocks and fixing components. Fine adjustment is achieved by knurled nuts and flange nuts, which increases the contact area between the backlight tape and the screen, activates the adhesion, and protects the four corners of the screen.
It improves the product yield rate, facilitates subsequent adhesion verification, adapts to different product specifications, avoids damage to the four corners of the screen, and ensures high-quality production.

Description
Technical Field
[0001] This utility model relates to the field of ballast holding platform technology, and more particularly to AT ballast holding platform. Background Technology
[0002] In the LCD industry, AT (Automated Testing) is a crucial step in ensuring product quality and production efficiency. During the panel and backlight assembly process, without an AT pressure-holding stage, the backlight rises with the stage and doesn't directly contact the panel. This results in the adhesive tape at the backlight edges failing to adhere properly to the panel, leading to issues like backlight separation and reduced yield. The AT pressure-holding stage, through its unique design, such as grooved surfaces and movable adhesive buffer blocks, elevates the panel, increasing the contact area between the backlight tape and the panel to activate adhesion. It also avoids damage at the corners, improving product yield and meeting the demands of AT testing for enhanced product quality and precise operation, thus ensuring the efficient and stable operation of the entire production process.
[0003] Traditional AT pressure-holding stages involve raising the stage along with the backlight to allow for bonding between the backlight and the screen. However, this method has drawbacks. During bonding, the screen and backlight do not make direct contact, resulting in insufficient adhesion between the tape at the backlight's edge and the screen. This can easily lead to issues like adhesive failure at the back end, affecting product yield. Furthermore, it lacks effective measures to adapt to different product specifications, protect vulnerable areas like the screen's corners, and verify adhesion later on. Overall, its effectiveness is limited and it fails to meet the demands of high-quality production.
[0004] When using a traditional AT pressure carrier, the carrier lifts the backlight and combines it with the screen. However, the screen and backlight do not make direct contact during the combination, which means that the adhesive tape at the edge of the backlight and the screen are not activated, which can easily lead to problems such as the backlight coming unglued and thus affect the yield rate. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an AT bearing plate, which aims to improve the problem that the traditional AT bearing plate does not have direct contact between the screen and the backlight when they are combined, resulting in the adhesiveness between the tape at the edge of the backlight and the screen not being activated, which can easily lead to the back end peeling off and thus affect the yield.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an AT pressure-holding platform, comprising a platform, wherein the platform has four oblique sliding grooves inside and four straight sliding grooves inside, and a raising component is provided inside the platform for raising the screen.
[0007] The shim assembly includes an upper rubber-coated buffer block and a lower rubber-coated buffer block. The outer wall of the upper rubber-coated buffer block is slidably connected to the inside of the platform, and the outer wall of the lower rubber-coated buffer block is slidably connected to the inside of the platform.
[0008] Furthermore, an upper sliding plate is fixedly connected to the lower surface of the upper rubber-coated buffer block, and a lower sliding plate is fixedly connected to the upper surface of the lower rubber-coated buffer block. A fixing component is provided inside the lower sliding plate, and the fixing component is used to fix the movement of the upper rubber-coated buffer block and the lower rubber-coated buffer block.
[0009] Furthermore, the fixing component includes a knurled nut, the outer wall of which is disposed inside the lower slide plate, and a flange nut is disposed inside the upper slide plate.
[0010] Furthermore, the outer wall of the upper sliding plate is slidably connected to the inner wall of the platform, and the upper sliding plate is used to drive the upper rubber-coated buffer block to move.
[0011] Furthermore, the outer wall of the lower sliding plate is slidably connected to the inner wall of the platform, and the lower sliding plate is used to drive the lower rubber-coated buffer block to move.
[0012] Furthermore, the four inclined slides are arranged in a circular array inside the platform, and the four straight slides are arranged symmetrically inside the platform.
[0013] Furthermore, the stage is made of 6061 aluminum alloy.
[0014] Furthermore, the upper rubber-coated buffer block and the lower rubber-coated buffer block are slidably connected inside the inclined slide groove and the straight slide groove.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, by processing grooves in all directions of the carrier platform and cooperating with movable rubber-coated buffer blocks, the screen is raised, which increases the contact area between the backlight tape and the screen, activates the adhesiveness of the tape, and avoids damage points at the four corners; improves the product yield rate, and solves the problem that when the pressure carrier platform screen and the backlight are combined, there is no direct contact, which leads to the adhesiveness between the tape at the edge of the backlight and the screen not being activated, which easily leads to the back end peeling off and thus affects the yield rate.
[0017] 2. In this utility model, the lower slide plate and the upper slide plate are loosened and fixed by knurled nuts and flange nuts, thereby enabling fine adjustment of the position of the upper rubber-coated buffer block and the lower rubber-coated buffer block, which facilitates the verification of the adhesion of the backlight tape in the later stage.
