Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal display panel bonding, and in particular to a panel bonding device for producing liquid crystal display panels. Background Art

[0002] With the continuous development of science and technology and the advancement and improvement of technology, new display technologies such as LCD and OLCD have emerged and developed. Liquid crystal displays have been able to achieve a wider viewing angle because of their lightness, low power consumption and good image quality, so that the image quality does not change much when viewing the screen from different angles. Therefore, liquid crystal displays are a display technology widely used in televisions, computer monitors, collection screens and other devices.

[0003] The Chinese patent with publication number CN221281360U and name “A liquid crystal display screen bonding device” comprises a groove, in which a bidirectional screw is rotatably installed, in which the slider is slidably installed, a positioning clamping plate is fixedly connected to one side of the slider, a gear is installed at the output end of the servo motor, a sliding block is slidably installed in the slide groove, a rack is fixedly connected to the top side of the sliding block, and a T-block is slidably installed in the sliding cavity; the display screen is placed on the workbench, and the handle is turned in coordination with the scale lines according to the width of the display screen, and the bidirectional screw will rotate, driving the two sliders and the positioning clamping plate to move toward each other in the groove, and then the servo motor is started, the gear drives the rack to move, the sliding block will slide in the slide groove, and then drive the T-block and the fixed clamping plate to slide in the sliding cavity, thereby realizing the precise positioning of the display screen, ensuring that the display screen and the panel are more closely and accurately bonded, reducing the bonding error, and improving the quality of the product.

[0004] The prior art of the above patent can also realize the bonding of LCD display panels, but the existing LCD display bonding device does not take into account the position adjustment of the LCD panel. If only the display frame is adjusted, it is possible that the LCD bottom plate on the display frame and the LCD panel are not properly bonded. Secondly, when the existing LCD display bonding device bonds the display, the display frame can only be put back after the bonding work is completed, thereby increasing the waste of working time.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-Figure 11A panel bonding device for liquid crystal display production provided in an embodiment of the present invention includes: a conveying frame 1, which is in a U-shaped structure, and a support frame 11 is fixedly installed on the upper part of the conveying frame 1, and the support frame 11 is in an F-shaped structure; a conveying component 2, which is fixedly installed inside the conveying frame 1, and the conveying component 2 is used to uniformly convey the display screen frame to the right; an adjustment component 3, which is fixedly installed inside the support frame 11, and the adjustment component 3 is used to limit the position of the display screen frame on the conveying component 2; a conveying component 4, which is fixedly installed on the front side wall of the conveying frame 1, and the conveying component 4 is used to uniformly convey the liquid crystal panel upward and adjust the position; an adsorption component 5, which is fixedly installed on the lower side of the support frame 11, and the adsorption component 5 is used to adsorb and drive the liquid crystal panel from the position of the conveying component 4 to the position of the display screen frame.

[0032] In the above technical scheme, the display screen frame is placed on the conveying component 2. As the conveying component 2 conveys the display screen frame, when the conveying component 2 reaches the position of the adjusting component 3, the adjusting component 3 squeezes the conveying component 2 so that the position of the display screen frame on the conveying component 2 is in the center position, and the liquid crystal panels are placed centrally on the conveying component 4. The conveying component 4 adjusts the horizontal and vertical positions of the liquid crystal panels so that the liquid crystal panels are completely in the center position. After the adsorption component 5 completes the adsorption of the liquid crystal panel on the top layer of the conveying component 4, as the conveying component 4 works, the liquid crystal panel on the next layer moves upward, and as the adsorption component 5 moves backward, when the adsorption component 5 drives the liquid crystal panel to the position of the display screen frame, the adsorption component 5 suspends adsorption, and at the same time, the adsorption component 5 presses the liquid crystal panel downward to make the liquid crystal panel fit with the liquid crystal bottom plate in the display screen frame.

[0033] See also Figure 2 and Figure 4 As shown, as the preferred technical solution of this embodiment, the conveying assembly 2 includes a conveyor 21, a placement frame 23, a connecting block 24 and a limiting mechanism 25. The conveyor 21 is fixedly installed inside the conveying frame 1, and the placement frames 23 are evenly arranged on the conveyor 21. The placement frame 23 is fixedly connected to the conveyor 21 through the connecting block 24, and a slidable limiting mechanism 25 is installed inside the placement frame 23.

[0034] In the above technical solution, the display screen frame is placed on the placement frame 23. As the conveyor 21 works, the liquid crystal panel follows the placement frame 23 to move to the right, and the limiting mechanism 25 follows the movement. When the placement frame 23 reaches the position of the adjustment component 3, the adjustment component 3 squeezes the limiting mechanism 25. At the same time, the limiting mechanism 25 adjusts the horizontal and vertical positions of the display screen frame in the placement frame 23 so that the display screen frame is located at the center position of the placement frame 23.

[0035] See Figure Figure 4As shown, as a preferred technical solution of this embodiment, the limiting mechanism 25 includes a telescopic rod 251, a connecting plate 252, a push plate 1 253, a limiting rod 254, a push plate 255 and a connecting line 1 256.

The placement frame 23 is provided with front and rear symmetrical sliding grooves, and a push plate 1 253 is slidably arranged inside the sliding groove. The push plate 1 253 is fixedly installed at the inner end of the telescopic rod 251. A push groove is provided inside the placement frame 23, and the structure of the push groove is L-shaped. The push groove is connected to one of the slide grooves. A limit rod 254 is slidably arranged in the push groove. The limit rod 254 is fixedly installed on the outer sleeve of the telescopic rod 251, and the end of the limit rod 254 is fixedly connected to one end of the connecting line 1 256.

The other end of the connecting line 1 256 is fixedly connected to the push plate 255, and the push plate 255 is connected to the placement frame 23 through a spring.

[0036] In the above technical solution, when the placement frame 23 moves to the position of the adjustment component 3, the adjustment component 3 squeezes the connecting plate 252 inward, and the telescopic rod 251 drives the push plate 1 253 and the limit rod 254 to follow the movement, and the push plate 1 253 adjusts the longitudinal position of the display screen frame, and the limit rod 254 pulls the push plate 2 255 inward through the connecting line 1 256, and the push plate 2 255 adjusts the lateral position of the display screen frame. When the push plates 1 253 and 255 are both tightly attached to the display screen frame, the display screen frame is at the center position of the placement frame 23, ensuring that the adsorption component 5 can drive the liquid crystal panel to fit accurately to the liquid crystal bottom plate in the display screen frame during work.

[0037] In addition, if the two push plates 1 253 are in close contact with the display screen frame and the two push plates 255 have not reached a state of symmetrical contact with the display screen frame, the adjustment component 3 continues to squeeze inward, the telescopic rod 251 contracts, the outer sleeve of the telescopic rod 251 continues to move inward, the outer sleeve of the telescopic rod 251 drives the limit rod 254 to continue to move inward, and the limit rod 254 drives the push plates 2 255 to continue to move inward through the connecting line 1 256 until the display screen frame is at the center position.

The push frame 34 is symmetrically installed on the bidirectional lead screw 33 through a threaded transmission method. The push frame 34 is an L-shaped structure, and a limiting groove is provided on the push frame 34. The limiting groove is slidably provided with a positioning rod 35, and the positioning rod 35 is fixedly installed on the inner wall of the support frame 11.

[0039] In the above technical solution, when the placement frame 23 moves to the bottom of the support frame 11, the motor 32 drives the bidirectional screw 33 to rotate, and the bidirectional screw 33 causes the two push frames 34 to move towards each other at the same time. The push frames 34 squeeze the connecting plate 252 to control the limit mechanism 25 to adjust the limit of the display frame.

[0048] In the above technical solution, when the electric slider 55 drives the sliding frame 54 to slide to the position of the top block 53 above the conveying component 4, the top block 53 squeezes the support block 56 and the cylinder 59 downward, and at the same time, the cylinder 59 drives the suction cup 58 to adsorb the liquid crystal panel. After the adsorption is completed, the cylinder 59 drives the liquid crystal panel to move upward, and the electric slider 55 slides backward. When the electric slider 55 slides to the position of the top block 53 above the conveying component 2, the top block 53 squeezes the support block 56, so that the support block 56 drives the liquid crystal panel to move downward. At this time, the cylinder 59 drives the liquid crystal panel to move downward, so that the liquid crystal panel fits with the display frame, and then the suction cup 58 stops adsorbing the liquid crystal panel, and the adsorption component 5 repeats the above steps to continue the operation.
