Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a liquid crystal display module separation platform. Background Art

[0002] When the touch display integrated module uses OCA glue (optical glue) to bond the LCD component (liquid crystal component) to the protective cover plate, foreign matter from the environment is mixed in, which requires the LCD component to be separated from the protective cover plate to achieve rework and reuse of related materials. The current separation is divided into cold separation and hot separation. The hot separation method is to place the module to be removed on a high-temperature ironing plate and fix it by vacuum adsorption. While heating at high temperature, use the screen cutting line to pull the OCA between the LCD component and the protective cover plate to separate the LCD component from the protective cover plate. There are the following problems when using this method: 1. When the screen cutting line is pulled left and right, a certain pressure needs to be applied in the cutting direction. Due to many reasons such as the inconsistency between the pressure direction of the vacuum adsorption and the like, the LCD display module will slide during cutting, thereby affecting the cutting effect and efficiency. 2. When the screen cutting line is pulled left and right, it will rub against the edge of the platform, affecting the service life of the screen cutting line.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a liquid crystal display module separation platform.

[0005] The technical solution of the utility model is as follows: The utility model provides a liquid crystal display module separation platform, including: a heating platform, a concave area for accommodating and positioning the liquid crystal display module is formed on the heating platform, a bottom array of the concave area is provided with a plurality of vacuum adsorption holes, and a rotating rod is respectively provided on both sides of the heating platform, and the rotating rod can rotate freely.

[0006] Furthermore, the two rotating rods are arranged in parallel.

[0007] Furthermore, the concave area is rectangular, and the side of the concave area forms an angle of 45 degrees with the rotating rod.

[0008] Furthermore, the concave depth of the concave area corresponds to the same thickness of the cover plate of the separated liquid crystal display module.

[0009] Furthermore, both ends of the rotating rod are arranged on the rotating rod seat through bearings.

[0013] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Please refer to Figure 1 and Figure 2 In this embodiment, the utility model provides a liquid crystal display module separation platform, including: a heating platform 1, a recessed area 11 for accommodating and positioning a liquid crystal display module 3 is formed on the heating platform 1, when the liquid crystal display module 3 is placed in the recessed area 11, it is limited by the side wall of the recessed area 11 to prevent the liquid crystal display module 3 from moving during operation, a bottom array of the recessed area 11 is provided with a plurality of vacuum adsorption holes, which can adsorb the liquid crystal display module 3 placed in the recessed area 11, and a rotating rod 2 is respectively provided on both sides of the heating platform 1, and the rotating rod 2 can rotate freely.

[0015] Furthermore, the two rotating rods 2 are arranged in parallel.

[0016] Furthermore, the recessed area 11 is rectangular, and the side of the recessed area 11 forms an angle of 45 degrees with the rotating rod 2. With this structure, the liquid crystal display module 3 placed in the recessed area 11 can also be set at 45 degrees with the rotating rod 2. In this way, when cutting, the screen cutting line 4 first contacts and cuts a corner of the liquid crystal display module 3, which makes the cutting operation more convenient and improves the cutting efficiency.

[0017] Furthermore, the concave depth of the concave area 11 is the same as the thickness of the cover plate of the corresponding separated liquid crystal display module 3 .

[0018] Furthermore, both ends of the rotating rod 2 are arranged on the rotating rod 2 seat through bearings.

[0019] Please continue to refer to Figure 1 and Figure 2 In this solution, the cover plate of the liquid crystal display module 3 is placed downward in the concave area 11, and the screen cutting line 4 (made of tungsten alloy steel wire) is arranged along Figure 1The OCA glue of the liquid crystal display module 3 is cut in the direction of the arrow shown. Due to the setting of the rotating rod 2, the two ends of the screen cutting line 4 can be respectively against the two rotating rods 2 when cutting. When the screen cutting line 4 is pulled left and right, the rotating rod 2 can rotate with the screen cutting line 4, thereby reducing the corresponding friction and loss of the screen cutting line 4.

[0020] In summary, the beneficial effects of this solution are: it can facilitate cutting, improve cutting efficiency, and reduce the wear and tear of the screen cutting line.

[0021] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
