Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: an auxiliary positioning device for liquid crystal display screen detection, including an operating table 1, a support frame 2 is provided on the upper end surface of the operating table 1, and a first servo motor 3 is embedded in the support frame 2. One end of the output shaft of the first servo motor 3 is connected to the rotating shaft 4 through a coupling, and a placing plate 5 is provided on the outer wall of the rotating shaft 4. A plurality of support blocks 6 are provided at the lower end of the placing plate 5, and a liquid crystal display screen is placed above the support blocks 6.

[0021] Furthermore, under the action of the first servo motor 3, the placing plate 5 forms a rotating structure with the support frame 2 through the rotating shaft 4, so that the placed liquid crystal display screen can be conveniently adjusted in angle through the rotatable placing plate 5, and thus various detections of the liquid crystal display screen can be conveniently carried out.

[0022] A second servo motor 7 is provided in the middle at the lower end of the placing plate 5, and an output shaft is provided below the second servo motor 7. A fixing frame 8 is provided on the outer wall of the output shaft, and a plurality of fixing blocks 9 are provided behind the fixing frame 8. Limiting rods 10 are respectively inserted into the fixing blocks 9, and the limiting rods 10 are inserted into the fixing plate, and the fixing plate is provided on the lower end surface of the placing plate 5. The other end of the limiting rod 10 is connected to the pulling plate 12, and a spring 11 is provided on one end surface of the pulling plate 12, and the other end of the spring 11 is connected to the fixing plate.

[0023] Further, the fixing frame 8 forms a rotating structure with the placing plate 5 through the output shaft under the action of the second servo motor 7, so that the liquid crystal screen can be quickly driven to perform limit flipping under the action of the second servo motor 7 for multi-directional detection. Moreover, the fixing frame 8 forms an elastic snap-in limit structure with the placing plate 5 through the fixing block 9, the limiting rod 10, and the spring 11, thereby increasing the stability of the limiting plate assembly during placement through the elastic limiting component.

[0024] The fixing frame 8 is internally provided with a third servo motor 13, and one end of the output shaft of the third servo motor 13 is connected to a bidirectional screw 14 through a coupling. A slide rod 15 is correspondingly arranged below the bidirectional screw 14, and movable blocks 16 are respectively inserted through both ends of the bidirectional screw 14 and the slide rod 15.

[0025] Further, the movable block 16 forms a bidirectional limit sliding structure with the fixing frame 8 through the bidirectional screw 14 and the slide rod 15 under the action of the third servo motor 13, so that the liquid crystal screen is squeezed and limited by the limit plate 19 with bidirectional limit sliding for limit placement.

[0026] The movable block 16 is provided with a concave fixing frame 17 above it, and a rotating rod 18 is inserted through the concave fixing frame 17. Threads are respectively arranged on the outer walls of both ends of the rotating rod 18, and spiral holes are correspondingly opened on the concave fixing frame 17. A limit plate 19 is arranged on the outer wall of the rotating rod 18, and the liquid crystal screen is located between the limit plates 19.

[0027] Further, the limit plate 19 forms a rotating structure with the concave fixing frame 17 through the rotating rod 18, and the limit plate 19 forms a spiral locking structure with the concave fixing frame 17 through the threads at both ends of the rotating rod 18 and the spiral holes. Thus, when performing relevant operations on the side of the liquid crystal screen, the limit plate 19 can be driven to rotate through the rotating rod 18.

[0028] Working principle: When using the auxiliary positioning device for liquid crystal screen detection, first place the liquid crystal screen on the support block 6. At the same time, the third servo motor 13 can be started. The output shaft of the third servo motor 13 drives the bidirectional screw 14 to rotate through a coupling, so as to drive the limit plate 19 to perform bidirectional limit sliding through the slide rod 15 and the movable block 16, thereby squeezing and limiting the liquid crystal screen through the limit plate 19, so as to limit the placement of the liquid crystal screen, and then facilitate subsequent various detection operations on it; after the liquid crystal screen is placed in a limited position, the first servo motor 3 can be started. The output shaft of the first servo motor 3 drives the rotating shaft 4 to rotate through a coupling, so as to adjust the angle of the placing plate 5, thereby facilitating various detections of the liquid crystal screen, and at the same time facilitating the inspection of the condition of the liquid crystal screen during the detection process; after one side of the liquid crystal screen is detected, the pull plate 12 can be pulled backward, so as to take out the limit rod 10 from the fixed block 9. At the same time, the second servo motor 7 can be started. The second servo motor 7 drives the limit component through the output shaft to drive the liquid crystal screen to quickly perform limit flipping, so as to facilitate the detection of the other side of the liquid crystal screen. After the liquid crystal screen is flipped, the fixed frame 8 component can be clamped and limited through the limit rod 10, so as to increase the stability of the limit plate 19 and its related components during operation through the limit rod 10 component; during the detection process, if it is necessary to detect the side of the liquid crystal screen, the limit plate 19 can be driven to rotate through the rotating rod 18, so as to ensure the limit operation of the liquid crystal screen while avoiding the influence of the limit plate 19 component on the detection of the liquid crystal screen. This is the usage process of the auxiliary positioning device for liquid crystal screen detection.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
