Description

An automatic transfer device for large display screens Technical Field

[0001] This invention belongs to the field of display manufacturing technology, specifically a large-scale automatic transfer device for display screens. Background Technology

[0002] A monitor is a computer's I / O device, that is, an input / output device. It is a display tool that displays certain electronic documents on a screen through a specific transmission device and then reflects them to the human eye. It can be divided into various types such as CRT and LCD.

[0003] An LCD screen is a type of display used in televisions and computers. Its advantages include low power consumption, small size, and low radiation. LCD screens use a liquid crystal solution in two polarizing materials. When an electric current passes through the liquid, the crystals rearrange to achieve the purpose of image formation.

[0004] During LCD display production, the COF electrode needs to be electrically connected to the substrate and PCB board. During production, ACF conductive adhesive is used for thermo-pressing to complete the electrical connection. To ensure subsequent product quality, in addition to checking the display by turning it on, a microscope is also needed to inspect the COF electrode and the PCB electrode to ensure that the deviation is below the standard. At this time, the display body needs to be manually transferred from the maintenance station, which takes up the time of turning on the screen at the maintenance station, resulting in reduced inspection efficiency. Secondly, during the transfer process, it is very easy to be bumped and damaged, resulting in fragments. When moving large displays, larger suction cups are often required to assist, further increasing the difficulty and safety of the display transfer. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] Example 1

[0034] Referring to Figures 1-8: A large-scale automatic transfer device for displays includes: a transfer housing 1 for storing the display body 4 to be tested; and a transfer assembly disposed inside the transfer housing 1. The transfer assembly includes a tilting frame 2, a main limiting plate 3, a secondary limiting plate 103, a storage box 6, and a drive assembly. Firstly, the transfer assembly enables stable transfer of the display body 4, facilitating connection to the display production line. After power-on testing, the display body 4 is randomly sampled and inspected at intervals. A microscope is used to detect the misalignment length between the PCB board electrodes and COF electrodes, and simultaneously, the particle size of the ACF conductive adhesive is detected, avoiding time spent on the testing station and improving testing efficiency. The tilting frame 2 is hinged to the top corner of the outer wall of the transfer housing 1. The main limiting plate 3 rotates via a pivot. The storage box 6 is slidably embedded in the center of the inner wall of the inclined frame 2. The secondary limiting plate 103 is fixedly set at the bottom of the outer wall of the main limiting plate 3. The storage box 6 is slidably embedded in the inner wall of the transfer shell 1 near the bottom. Two driving components are fixedly set at the center of both sides of the outer wall of the main limiting plate 3. Through the driving components, the transfer components can be stably driven. The buffer component is set at the bottom of the outer wall of the storage box 6. The buffer component includes a buffer cylinder 703, a buffer suction cup 704 and a buffer hole 601. The buffer hole 601 is opened at the corner of the inner wall of the storage box 6. The buffer hole 601 can facilitate the stable movement of the buffer suction cup 704 driven by the buffer cylinder 703. The buffer suction cup 704 is slidably embedded in the inner wall of the buffer hole 601. The buffer cylinder 703 is fixedly set at the bottom outer wall of the buffer suction cup 704.

[0035] Referring to Figures 1-8: The drive assembly includes a driven gear 201, a driving gear 202, and a transfer motor 101. The outer walls of the driving gear 202 and the driven gear 201 mesh with each other for transmission. The center of one side of the outer wall of the driving gear 202 is fixedly mounted at the output end of the transfer motor 101. The center of one side of the outer wall of the driven gear 201 is fixedly mounted at the center of both sides of the outer wall of the main limiting plate 3. The buffer assembly also includes an auxiliary frame 7, a reinforcing frame 701, auxiliary rollers 9, and a lifting cylinder 702. The reinforcing frame 701 is fixedly mounted at the bottom of the outer wall of the auxiliary frame 7. The auxiliary rollers 9 are rotatably embedded in the inner wall of the auxiliary frame 7. The lifting cylinder 702 is fixedly mounted at the center of the bottom of the outer wall of the reinforcing frame 701. The working height of the auxiliary frame 7 and the storage box 6 can be adjusted by the lifting cylinder 702 to facilitate the transfer assembly. To prevent component rotation and impact, sliding skirts 301 are fixedly installed at the corners of the outer walls of the main limiting plate 3 and the secondary limiting plate 103, which are far apart from each other. The outer wall of the sliding skirt 301 is slidably snapped with the display body 4. A rotating buckle 302 is inserted into the top of the outer wall of the sliding skirt 301. Positioning cylinders 203 are installed on both sides of the outer wall of the inclined frame 2, and the output end of the positioning cylinder 203 extends through to the inner wall of the inclined frame 2. Positioning holes 303 are opened on the outer walls of the main limiting plate 3 and the secondary limiting plate 103. The output end of the positioning cylinder 203 matches the positioning hole 303. Positioning plates 8 are fixedly installed on both sides of the outer wall of the auxiliary frame 7. Transfer ports 102 are opened on both sides of the outer wall of the transfer shell 1. A transplanting suction cup group 5 is provided on the top of the outer wall of the display body 4, and the transplanting suction cup group 5 is fixedly installed on the external moving component.

[0036] Working principle:

[0037] First, the display body, after PCB and COF hot pressing, is moved to the top of the outer wall of the main limiting plate 3 using the transfer suction cup assembly 5 and the outer wall moving assembly, ensuring that the corners of the display body are in contact with the inner wall of the sliding skirt 301. Then, the tilting frame 2 is driven to rotate by the external rotating assembly, causing the tilting frame 2 to tilt at a 60-degree angle. Subsequently, the display body is powered by the screen-on device for screen testing, which is performed by illuminating the backlight installed inside the main limiting plate 3. When the display body needs to be sampled for inspection, the positioning cylinder 203 is activated, causing the positioning hole 303 to release from the positioning cylinder 203. Then, the transfer motor 101 is started to drive the active... Gear 202 rotates, which in turn drives the driven gear 201, causing the main limiting plate 3 and the secondary limiting plate 103 inside the tilting frame 2 to rotate, so that the monitor body rotates into the interior of the transfer housing 1. Then, the lifting cylinder 702 is activated, which drives the auxiliary frame 7 and the storage box 6 to rise, so that the buffer suction cup 704 is attached to the outer wall of the monitor body. The rotating buckle 302 is driven to release the monitor body from its latched state. Then, through the buffer cylinder 703, the monitor body enters the interior of the storage box 6. The sampling personnel can then pull out the storage box 6. The auxiliary roller 9 guides the storage box 6 to ensure that the buffer hole 601 is aligned with the buffer suction cup 704.
