[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the production process of the liquid crystal display module, the product needs to be turned over so that the circuit board fits the back of the liquid crystal display module and then turned back. However, the turning requires the feeding fixture and the liquid crystal display module to be loosened before turning over, and then fixed, which is more troublesome.

[0020] 3. When pasting the anisotropic conductive adhesive, the surface of the liquid crystal display module is not cleaned, resulting in dust in the air sticking to the surface of the anisotropic conductive adhesive, or failing to completely adhere to the back of the liquid crystal display module, causing bubbles on the pasting surface and the anisotropic conductive adhesive itself to adhere to each other. The present invention sets an elimination component to enable the sponge to wipe the part of the liquid crystal display module to be pasted, and reduces static electricity on the surface of the liquid crystal display module through friction with a scraper, thereby reducing dust adsorbed on the surface of the liquid crystal display module. At the same time, after pasting is completed, the anisotropic conductive adhesive pasted on the back of the liquid crystal display module is squeezed to make the anisotropic conductive adhesive fit more closely to the back of the liquid crystal display module and reduce bubbles.

[0021] 4. When the anisotropic conductive adhesive is manually pasted, usually no protective measures are provided during the pasting process, so that the surface of the anisotropic conductive adhesive is easily adhered to other objects, affecting its viscosity. The present invention can reduce the contact area between the anisotropic conductive adhesive and the corrugated rod by providing a support component, thereby preventing the anisotropic conductive adhesive from contacting other objects while waiting to be flipped, which affects the viscosity of the anisotropic conductive adhesive.

[0042] The limiting mechanism 3 also includes a cylinder 302, the bottom of which is fixedly connected to the upper surface of the base 301 on a side away from the support assembly 307, and a rotating rod 303 is symmetrically arranged on the outer wall of the cylinder 302. The outer wall of the rotating rod 303 is rotatably connected to the outer wall of the cylinder 302, and the end of the cylinder 302 close to the support assembly 307 is fixedly connected to the first telescopic rod 304, the outer wall of the first telescopic rod 304 is fixedly connected to the first limiting rod 305, and the end of the first limiting rod 305 away from the first telescopic rod 304 is fixedly connected to the first cushion block 306.

[0043] When the feeding roller 2 transfers the LCD module to the base 301, the first limiting rod 305 and the supporting assembly 307 adjust the two ends of the LCD module, and then the cylinder 302 drives the rotating rod 303 to approach the LCD module from the other two ends, so that the LCD module is located in the center of the base 301. Then the staff will stick the anisotropic conductive glue on the LCD module respectively, and stick the other end of the anisotropic conductive glue directly on the circuit board. The top of the supporting assembly 307 is in contact with the connection of the anisotropic conductive glue. After the pasting is completed, the first limiting rod 305 and the supporting assembly 307 release the force to keep in contact with the LCD module but not squeeze it. At this time, the lifting column 309 drives the supporting plate 310 to rise, lifting the LCD module. High, then the rotating mechanism 4 clamps the LCD display module inside and lifts it, and at the same time, the anisotropic conductive glue adhered to the supporting component 307 is peeled off, and the circuit board is driven close to the back of the LCD display module during the lifting process. After flipping 180 degrees, the circuit board is completely pasted to the back of the LCD display module by the eliminating component 308, and the backlight panel is taken out from the inside of the cleaning mechanism 5, and quickly aligned with the LCD display module for installation, and the auxiliary staff quickly aligns and installs the backlight panel, LCD display module and frame, and helps to paste the circuit board to avoid the anisotropic conductive glue after pasting it on the LCD display module.

The adjusting component 406 moves on the bracket 402 to adjust the distance between it and the mounting seat 403 to adapt to liquid crystal display modules of different sizes. When the mounting seat 403 rotates, the adjusting component 406 follows the rotation.

The second telescopic column 404 and the third telescopic column 4062 drive the movable frame 405 to approach each other, and then the movable seat 4061 and the fixed seat 408 are approached to each other, clamping the frame of the liquid crystal display module and placing it inside the movable seat 4061 and the fixed seat 408. Then the first support rod 4063 and the second support rod 409 are rotated 90 degrees to support the front of the liquid crystal display module, and the first extension rod 4064 supports the bottom of the circuit board to increase the force area of ​​the liquid crystal display screen and reduce the force on the edge of the liquid crystal display module during the flipping process.

[0053] The two curved arcs of the corrugated rod 3076 contact the adhesive surface of the anisotropic conductive adhesive, which can reduce the contact area between the anisotropic conductive adhesive and the corrugated rod 3076, and prevent the anisotropic conductive adhesive from contacting other objects while waiting for flipping, so that the viscosity of the anisotropic conductive adhesive is affected. Then, the flipping mechanism drives the liquid crystal display module to lift and move away from the corrugated rod 3076, so that the circuit board is naturally close to the liquid crystal display module by gravity, and after flipping, the corrugated rod 3076 rotates away from the second limit rod 3073, the scraper 3082 rotates 180 degrees, and the slider 3081 moves to drive the pressing rod 3087 to move on the back of the liquid crystal display module. While the slider 3081 moves horizontally, the moving shell 3085 moves vertically on the scraper 3082, so that it forms a Z-shaped movement on the surface of the anisotropic conductive adhesive, so that the anisotropic conductive adhesive is more closely attached to the back of the liquid crystal display module. During this period, the staff aligns the backlight panel with the liquid crystal display module, saving the staff time to check whether the anisotropic conductive adhesive is firmly attached.

[0054] The specific workflow is as follows:

[0055] During operation, the staff stands in front of the limiting mechanism 3 and places the circuit board in the groove of the supporting assembly 307. The feeding roller 2 transfers the assembled liquid crystal display module to the limiting mechanism 3. During the transfer, the staff first places the backlight panel into the cleaning mechanism 5, and then places the frame into the cleaning mechanism 5, so that the backlight panel and the frame are transferred alternately on the inner wall of the cleaning mechanism 5. A vacuum cleaner is externally arranged on the top of the shell 501. After the backlight panel and the frame are inserted into the shell 501, the built-in power source drives the rotating shaft 504 to rotate, so that the backlight panel and the frame are squeezed by the rubber shaft 505 from top to bottom for easy transportation. At the same time, the cleaning ring 506 reciprocates and rotates on the rotating shaft 504. The surface of the cleaning ring 506 contacts and rubs with the backlight panel and the frame, and at its level. During the moving work, the cleaning ring 506 moves longitudinally, so that the dust on the backlight plate and the frame is separated from the surface and taken away by the vacuum cleaner. Then, the staff adjusts the distance between the movable seat 4061 and the mounting seat 403 before work. After the anisotropic conductive adhesive is pasted on the surface of the liquid crystal display module, the machine 1 drives the mounting seat 403 to rotate 90 degrees, and the mounting seat 403 drives the movable seat 4061 and the fixed seat 408 to rotate 90 degrees. At this time, the support plate 310 lifts the liquid crystal display module. During the rotation of the mounting seat 403 and the movable seat 4061, the liquid crystal display module enters the interior of the movable seat 4061 and the mounting seat 403 from the gap formed by the first square groove 4065 and the second square groove 411. The second telescopic column 4 04 and the third telescopic column 4062 drive the movable frame 405 to approach each other, then the movable seat 4061 and the fixed seat 408 approach each other and clamp the frame of the LCD module and are inside the movable seat 4061 and the fixed seat 408, then the first support rod 4063 and the second support rod 409 rotate 90 degrees to support the front of the LCD module, the first extension rod 4064 supports the bottom of the circuit board, increases the force area of ​​the LCD screen, reduces the force on the edge of the LCD module during the flipping process, and avoids the oversized LCD screen from breaking when flipping, then the machine 1 drives the bracket 402 to rotate 180 degrees, the movable seat 4061 and the fixed seat 408 rotate 90 degrees in the opposite direction and fall on the support plate 310 , the staff takes out the backlight panel inside the cleaning mechanism 5, quickly aligns it on the LCD module and installs it. After the installation is completed, repeat the above operation to turn the LCD module back, and release the LCD module to fix it inside the limiting mechanism 3. Then the mounting seat 403 is reset vertically above the machine 1. The cleaning mechanism 5 has the same angle as the mounting seat 403, and transfers the frame from the mounting seat 403 to the inside of the movable seat 4061, and approaches the LCD module under the rotation of the movable seat 4061 and the fixed seat 408, so that it is quickly aligned with the LCD module and placed on the front of the LCD module. After being installed by the staff, it is transferred from the other end through the feeding roller 2 to the next processing step to complete the installation of the LCD screen.
