[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figs. 1 to 4 The positioning fixture for assembling a display panel shown includes an operating table 1, with a cavity inside the operating table 1. An air extraction pipe 102 is fixedly connected to the side of the operating table 1. Adsorption holes 101 are evenly opened in the middle of the upper part of the operating table 1. Fixed posts 2 are symmetrically fixedly connected to the four corners of the upper part of the operating table 1. An angle plate 201 is fixedly connected to the lower end of the fixed post 2. A telescopic rod 3 is rotatably connected to the middle of the fixed post 2. A clamping member 5 is threadedly connected to the end of the telescopic rod 3 away from the fixed post 2. A length plate 4 is provided between the telescopic rod 3 and the clamping member 5.

[0024] It should be noted that the display panel is placed above the suction hole 101 on the operating table 1, and the clamping piece 5 is engaged with the four corners of the display panel. Observe the angle between the telescopic rod 3 on the angle plate 201 and the two side lines and the extension length of the telescopic rod 3 on the length plate 4. Adjust the values ​​of the angle plate 201 and the length plate 4 by moving the position of the display panel to keep them equal. At this time, the display panel is positioned in the center of the operating table 1, and then the display panel is suctioned and fixed through the suction hole 101.

[0025] It is worth noting that the suction pipe 102 is connected to a suction device, which can create a vacuum under the display panel and fix it on the operating table 1. This avoids damage to the display panel due to excessive clamping force. After the display panel is suction-fixed, the clamping part 5 may apply a certain force to the display panel under the action of the adjusting spring 302 during the subsequent assembly process. Since the display panel is mainly glued and fixed together with adhesive during the subsequent assembly process, it will not generate a large vibration. At the same time, due to the large suction force, the adjusting spring 302 will not shift the display panel during the subsequent assembly production process.

[0026] The embodiment of the application, preferably, the angle scale 201 is arranged in a straight angle sector, and the sector center of the angle scale 201 coincides with the cylindrical axis of the fixed column 2.

[0027] It should be noted that when the telescopic rod 3 rotates around the cylindrical axis of the fixed column 2 as the center, the angle between the telescopic rod 3 and the two side lines can be conveniently observed through the angle scale 201, and the angle between the telescopic rod 3 and the side line can be observed and adjusted in real time by adjusting the position of the display panel.

[0028] The embodiment of the application, preferably, the telescopic rod 3 is fixedly connected with an angle pointing plate 301 at one end close to the fixed column 2, and the angle pointing plate 301 is arranged perpendicularly to the angle scale 201.

[0029] It should be noted that the angle pointing plate 301 is perpendicular to and nearly close to the angle scale 201, so that the rotation angle of the telescopic rod 3 can be accurately observed from multiple angles, and the reading deviation caused by the observation angle is avoided, thereby avoiding the inaccurate positioning of the display panel.

[0030] The embodiment of the application, preferably, one end of the length scale 4 is slidably connected with the fixed end of the telescopic rod 3, and the other end of the length scale 4 is clampedly connected with the clamping piece 5.

[0031] It should be noted that the length scale 4 is synchronously telescoped with the telescopic rod 3, so that the length of the telescopic rod 3 can be displayed in real time, and the display panel can be accurately and centrally positioned through the cooperation and adjustment of the length scale 4 and the angle scale 201.

[0032] The embodiment of the application, preferably, the length scale 4 is fixedly connected with a clamping piece 401 at one end close to the clamping piece 5, a fixed groove 501 is correspondingly formed on the clamping piece 5, and the length scale 4 is clampedly connected with the clamping piece 5 through the clamping piece 401 and the fixed groove 501.

[0033] It should be noted that the length scale 4 has a certain elasticity, so that the length scale 4 can be taken off from the clamping piece 5 when the clamping piece 5 needs to be replaced, and the length scale 4 can be clampedly fixed on the clamping piece 5 through the clamping piece 401 after replacement, thereby improving the use flexibility of the positioning clamp.

[0034] The embodiment of the application, preferably, the telescopic end of the telescopic rod 3 is provided with a thread, a threaded hole 502 is correspondingly formed on the clamping piece 5, and the telescopic end of the telescopic rod 3 is connected with the inside of the clamping piece 5 through the thread.

[0035] It should be noted that the clamping piece 5 is connected with the telescopic end of the telescopic rod 3 through the thread, so that the clamping piece 5 can be conveniently disassembled, and can be suitable for positioning and clamping display panels of various specifications and models, and is also convenient and flexible to replace.

[0036] In a preferred embodiment of this application, hanging rings 503 are symmetrically arranged on both sides of the threaded hole 502, and the hanging rings 503 are fixedly connected to the clamping member 5; an adjusting spring 302 is arranged below the length plate 4, one end of the adjusting spring 302 is fixedly connected to the fixed end of the telescopic rod 3, and the other end of the adjusting spring 302 is engaged with the hanging ring 503.

[0037] It should be noted that the adjusting spring 302 applies a certain force to the telescopic rod 3, so that the clamping part 5 applies a center-directing push to the display panel while positioning, which plays an auxiliary role in fixing the display panel. One end of the adjusting spring 302 can be flexibly disassembled and assembled by engaging with the hanging ring 503, and can be quickly removed when replacing the clamping part 5.

[0038] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model.
