Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal screen detection equipment, and more specifically, to a detection head moving mechanism. Background Art

[0002] Liquid crystal screens use liquid crystal materials as basic components. Liquid crystal materials are filled between two parallel plates. Voltage is used to change the arrangement of molecules inside the liquid crystal material to achieve the purpose of shading and light transmission to display images of varying depths and staggered patterns. Moreover, as long as a three-primary color filter layer is added between the two flat plates, color images can be displayed. During the production process of LCD screens, in order to ensure the quality of the LCD screens, the LCD screens need to be tested.

[0003] According to the search, the Chinese patent with announcement number CN219179731U discloses a LCD bad pixel detection device, which includes a detection base and two side guard plates, a camera protection cover body is fixedly connected between the two side guard plates, two symmetrical guide rod mounting seats are installed inside the camera protection cover body, a polarizer is installed at the bottom end of the detection camera, a transverse track and a longitudinal track are opened at the top of the detection base, the transverse track is vertically arranged with the longitudinal track, a moving block is slidably installed inside the transverse track, and a LCD carrier is fixedly installed on the top of the moving block. The utility model is provided with a camera protection cover body between the two side guard plates, and the detection camera is driven to move in parallel with the longitudinal track by the electric drive block connecting seat. It can not only protect the detection camera, but also has a good dust-proof effect in combination with the foldable dust shield belt, and it is convenient to adjust the spatial position of the detection camera, which is very convenient for dealing with long LCD screens.

[0004] Regarding the above-mentioned related technologies, the applicant believes that it is not convenient to adjust the angle of the camera, resulting in that only the LCD screen on the carrier can be inspected, and it is not convenient to inspect special LCD screens that are difficult to place on the carrier, such as LCD screens that are too large or too small. For this reason, we propose a detection head moving mechanism. Utility Model Content

[0038] By setting the angle adjustment component 240, the detection head can be driven to rotate and adjust the angle, so as to facilitate the detection of LCD screens that are too large or too small, thereby improving practicality. By setting the driving component 220, the steering component 230 and the angle adjustment component 240 can be driven to telescopically move and adjust the position. By setting the steering component 230, the angle adjustment component 240 can be driven to rotate and adjust the position.

[0039] The angle adjustment component 240 includes an n-shaped block 241, the internal rotation of the n-shaped block 241 is connected to a rotating rod 242, one end of the n-shaped block 241 is fixedly connected to a first forward and reverse motor 243, and the output end of the first forward and reverse motor 243 is fixedly connected to one end of the rotating rod 242.
