Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screen detection, in particular to a flip device for liquid crystal screen detection. Background Art

[0002] Liquid crystal display, abbreviated as LCD in English, is a type of flat panel display. It is used for screen display of television and computer. The advantages of this display are low power consumption, small size and low radiation. The liquid crystal display uses a liquid crystal solution in two polarized materials, so that when the current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging.

[0003] 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 light shielding and light transmission to display images of varying depths and in an orderly manner. In addition, as long as a three-primary color filter layer is added between the two plates, color images can be displayed. Liquid crystal screens have very low power consumption, so they are favored by engineers and are suitable for electronic devices using batteries.

[0004] When the LCD screen is damaged, it is necessary to inspect the LCD screen. However, the existing inspection equipment requires the LCD screen to be in a horizontal state after being turned over so that the inspection contacts can inspect the LCD screen. However, the existing LCD screen is difficult to maintain balance and stability after being turned over, so it will shake during inspection, resulting in poor inspection effect.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-7 , a flip device for liquid crystal screen detection, comprising a detection platform 1, a detection mechanism 2 is disposed laterally on the top of the detection platform 1, and a flip mechanism 4 is disposed directly below the detection mechanism 2;

[0027] The flip mechanism 4 includes a U-shaped frame, a rotating handle 41 is provided on one side of the outside of the U-shaped frame, and the rotating handle 41 is connected to the flip frame 42 through a connecting shaft 47, and an electric telescopic rod 44 is provided on the inner side of the other end of the U-shaped frame, and a mounting shaft 4401 is provided at the end of the electric telescopic rod 44, and a flip connection plate mechanism 46 is provided on the other side of the flip frame 42;

[0028] The flip connection disk mechanism 46 includes a fixed disk 4602 , and a second key slot 4603 is formed on the fixed disk. A rotating disk is disposed on the other side of the fixed disk 4602 , and a first key slot 4601 is formed on the rotating disk.

[0029] A mounting convex key 4402 is disposed on the top of the mounting shaft 4401 , and the mounting convex key 4402 is matched with the first key groove 4601 and the second key groove 4603 .

[0030] At the same time, a mounting frame 45 is arranged on the inner side wall of the flip frame 42, and the mounting frame 45 is "U"-shaped, and a rubber limiting pad 4501 is arranged at the groove of the mounting frame 45, and the rubber limiting pad 4501 can protect the frame of the LCD screen.

[0031] In addition, a hydraulic device 21 is provided on the top of the detection mechanism 2, and a detection contact 22 is provided in the bottom middle section of the hydraulic device 21. The detection contact 22 can detect the surface of the liquid crystal screen. This is the prior art and will not be described in detail.

[0032] Furthermore, slots 43 are formed at the top and bottom of the flip frame 42 , and when the flip frame 42 is in a vertical state, the slots 43 are located directly below the detection contacts 22 .

[0033] Moreover, the included angle between the second key slot 4603 and the first key slot 4601 on the fixed plate 4602 is 90°, a main controller 3 is arranged on the side of the detection mechanism 2, and the hydraulic equipment 21, the electric telescopic rod 44 and the detection contact 22 are connected to the main controller 3 through electrical signals.

[0034] In this embodiment, the LCD screen needs to be placed inside the flip frame 42 first, and the two sides of the LCD screen are placed in the installation frames 45 on both sides respectively, and are clamped with rubber limit pads 4501 to ensure that they will not be damaged.

[0035] Then, the main controller 2 is used to drive the electric telescopic rod 44 inside the flip mechanism 4 to extend, so that the mounting convex key 4402 on the top of the mounting shaft 4401 at the movable end of the electric telescopic rod 44 is inserted into the first key slot 4601 provided on the flip connecting plate mechanism 46, and the mounting shaft 4401 can be connected to the shaft at the end of the mounting frame 45 and can be driven to rotate.

[0036] Then rotate the rotating handle 41 on the other side of the flip mechanism 4, and then the rotating handle 41 drives the installation frame 45 on one side to rotate through the connecting shaft 47. Since a liquid crystal screen is installed on the installation frame 45, the rotation of the installation frame 45 on this side will drive the installation frame on the other side to rotate in the same way. Therefore, when the installation frame 45 is rotated 90° counterclockwise by rotating the handle 41, the installation cam 4402 on the installation shaft 4401 will be on the same axis with the second key slot 4603 opened on the fixed plate 4602.

[0037] At this time, the electric telescopic rod 44 is driven by the main controller 4 to continue to extend forward, so that the mounting convex key 4402 on the mounting shaft 4401 is inserted into the second key slot 4603 provided on the fixed plate 4602. Since the second key slot 4603 is on the fixed plate 4602 and the fixed plate 4602 does not rotate, the mounting shaft 4401 will drive the rotating handle 41 on the other side to be in a stuck state, and make the LCD screen in the mounting frame 45 in a horizontal state and relatively stable.

[0038] Then, the hydraulic device 21 is controlled by the main controller 3 to move downward, and then the detection contact 22 is enabled to detect the liquid crystal screen in a stable horizontal state.

[0039] In the utility model, firstly, the LCD screen can be stably fixed by the mounting frame 45, and the LCD screen can be protected by the rubber limit pad 4501, and then the rotating handle 41 can be stuck by deflecting the second key slot 4603 provided by the fixing disk 4602 of the third section on the flip connection disk mechanism 46, and the LCD screen can be placed in a stable horizontal state, so that the detection contact 22 can perform stable detection when detecting the surface of the LCD screen.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
