Technical Field

[0001] This utility model relates to the field of display panel processing technology, specifically to a bonding fixture for display panel processing. Background Technology

[0002] During the manufacturing process of display panels, a fixture is used to attach the film layer to the display panel, making the positional accuracy of the attachment particularly important.

[0003] The current display panel market has an increasing demand for product diversification, with display panels of various sizes and specifications constantly emerging. In the film lamination process, the precise alignment of the upper and lower clamps has become crucial. Traditional methods require operators to adjust the positions of the upper and lower clamps separately, which not only requires extremely high operational precision but is also prone to clamp tilting or shifting due to human factors, thus causing lamination alignment deviations and affecting product yield. To address this, we propose a lamination clamp for display panel processing. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1 to 5 As shown, a bonding fixture for display panel processing includes: a base 1, a bottom positioning plate 12 fixedly mounted on the top of the base 1, a first sliding groove 14 formed on the top of the base 1, a lead screw 141 passing through the inside of the first sliding groove 14, a rocker arm 142 fixedly connected to the right side of the lead screw 141 passing through the base 1, a slider 143 movably connected to the outside of the lead screw 141, a bottom clamping plate 144 fixedly connected to the top of the slider 143, two sets of sliding pillars 145 fixedly connected to the top of the bottom clamping plate 144, a limit block 146 fixedly connected to the top of the sliding pillars 145, and a fixed end block 146 at the rear edge of the top of the base 1. A fixed frame 2 is provided, and a pressing mechanism 21 is provided at the front end of the fixed frame 2. A push rod 22 is connected to the bottom end of the pressing mechanism 21. An elastic element 23 is fixedly connected to the bottom end of the push rod 22. A connecting block 24 is fixedly connected to the bottom end of the elastic element 23. A pressing plate 3 is fixedly connected to the periphery of the connecting block 24. Two sets of guide rails 31 are provided on the right side of the pressing plate 3. A second sliding groove 32 is provided on the outer side of the guide rails 31. A top clamping plate 33 is movably connected to the bottom of the pressing plate 3. A protrusion 331 is provided at both ends of the top edge of the top clamping plate 33. A top positioning plate 34 is fixedly provided on one side of the bottom of the pressing plate 3.

[0024] In this implementation scheme: the bottom positioning plate 12 serves to position the bottom film layer, the top positioning plate 34 serves to position the top display panel device, the right rocker arm 142 adjusts the position of the upper and lower clamping plates through the screw 141 structure, clamps and fixes the upper and lower structures at the same time, and then drives the lower pressure plate 3 to press down through the push rod 22, so that the upper and lower parts fit together.

[0025] like Figures 1 to 2As shown, the slider 143 is threadedly connected to the lead screw 141, and the lead screw 141 forms a linkage structure with the bottom clamping plate 144 through the slider 143.

[0026] In this embodiment: the rocker arm 142 drives the lead screw 141 to rotate, causing the slider 143 to move the bottom clamping plate 144 left and right to clamp the film layer.

[0027] like Figures 1 to 4 As shown, the sliding column 145 is slidably connected to the guide rail 31, the top clamping plate 33 is sleeved on the outside of the sliding column 145, and the bottom clamping plate 144 forms a linkage structure with the top clamping plate 33 through the sliding column 145.

[0028] In this embodiment: the sliding column 145 slides along the guide rail 31 under the drive of the bottom clamping plate 144, and the top clamping plate 33 slides synchronously with the sliding column 145 to synchronously clamp the top display panel device.

[0029] like Figures 3 to 4 As shown, the outer diameter of the protrusion 331 is the same as the inner diameter of the second groove 32, and the protrusion 331 is slidably connected to the second groove 32.

[0030] In this embodiment, the protrusion 331 is embedded inside the second slide groove 32 and slides inside the second slide groove 32 under the action of the top clamping plate 33, thus connecting the lower pressure plate 3 and the top clamping plate 33.

[0031] like Figure 1 and Figure 5 As shown, the push rod 22 is elastically connected to the connecting block 24 through the elastic element 23, the pressing mechanism 21 forms a linkage structure with the connecting block 24 through the push rod 22, and the connecting block 24 forms a linkage structure with the top clamping plate 33 through the pressing plate 3.

[0032] In this implementation scheme: the elastic element 23 acts as a buffer to prevent excessive downward pressure from damaging the display panel. The push rod 22 extends downward to push the lower pressure plate 3 downward, which in turn drives the top clamping plate 33 to move downward in sync, achieving the purpose of fitting.

[0033] like Figures 1 to 4 As shown, silicone pads 13 are provided on the inner sides of the bottom positioning plate 12, the top positioning plate 34, the bottom clamping plate 144 and the top clamping plate 33, and the bottom positioning plate 12 and the top positioning plate 34 are arranged in an L-shape.

[0034] In this embodiment: the silicone pad 13 acts as a buffer to prevent damage to the display panel and the film layer, and the bottom positioning plate 12 and the top positioning plate 34 are arranged in an L-shape to enable bidirectional positioning of the front end and the left side.

[0035] Working principle: When using this display panel bonding fixture, the operator places the film layer to be bonded along the bottom positioning plate 12, then places the display panel equipment along the top positioning plate 34 and holds it up, thus completing the initial positioning work. Rotating the right-side rocker arm 142 drives the lead screw 141 to rotate, and with the connection of the sliding column 145, the bottom clamping plate 144 and the top clamping plate 33 move inward synchronously until they clamp the upper and lower components simultaneously. Then, the operator activates the pressing mechanism 21 through an external power source. The push rod 22 extends downwards to push the lower pressure plate 3 downwards, causing the equipment inside the top clamping plate 33 to move downwards, achieving the purpose of bonding with the film layer. The upper and lower linkage clamping plate design allows for synchronous adjustment of the upper and lower clamping positions simply by turning the rocker arm, achieving one-button synchronous clamping and fixing. High-precision alignment can be ensured without cumbersome calibration. At the same time, this structure is highly adaptable and can be flexibly applied to the bonding needs of display panels of different sizes, greatly improving operational efficiency and versatility. The upper and lower pressing mechanism is a pneumatic push rod, and the lifting can be controlled by a solenoid valve. The model can be matched with the working requirements.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
