[0033] Example
[0034] At present, for mid- and low-end LCD screens, the unified sizes and interface pin definitions of different manufacturers are generally the same. However, for the inspection of various types of LCD screens, it is necessary to make a corresponding inspection tool for each model. In addition, when inspecting different models of LCD screens, the inspectors need to use different inspection tools. This is more troublesome and costly.
[0035] In view of this, if Figure 1-Figure 3 As shown, in the first aspect, an embodiment of the present application provides a test tool, including: a tool base plate 10; a fixed mounting plate 20, which is rotatably connected to one side of the tool base plate 10, and a display circuit board 201 is provided on one side of the fixed mounting plate 20, and a cable adapter plate 202 is provided on the other side thereof, wherein the cable adapter plate 202 is used to connect the display circuit board 201 and the liquid crystal screen.
[0036] Exemplarily, the material of the tooling base plate 10 includes but is not limited to bakelite, the fixed mounting plate 20 includes but is not limited to acrylic plate, the fixed mounting plate 20 is rotatably connected to the tooling base plate 10, and the rotation angle of the fixed mounting plate 20 relative to the tooling base plate 10 can be 0°~180°, such as 30°, 40°, 50° or 60°, etc. The rotation angle is not specifically limited and can be set according to actual conditions, and is not specifically limited here; wherein the installation method of the fixed mounting plate 20 and the tooling base plate 10 can adopt a hinge 50, or the fixed mounting plate 20 and the tooling base plate 10 can be connected by a rotating shaft, etc.
[0037] It is understandable that the display circuit board 201 can be programmed to enable the liquid crystal screen to display full white, full black, red, green, blue or gray, etc.
[0038] During the above implementation process, the fixed mounting plate 20 is rotatably connected to the tooling base plate 10, and a display circuit board 201 is provided on one side of the fixed mounting plate 20. The fixed mounting plate 20 can be flipped relative to the tooling base plate 10 to facilitate replacement of the display circuit board 201, thereby testing LCD screens of different sizes.

[0040] For example, in order to facilitate the test personnel to input instructions and observe the large color serial port screen 101, the large color serial port screen 101 can be set to be tilted relative to the tooling base plate 10, wherein the angle between the interface of the large color serial port input instruction and the tooling base plate 10 can be set to 90° to 180°, for example, the tilt angle is 135°, 140° or 150°, etc., of course, other angle ranges are not excluded.
[0041] It is understandable that the large color serial port screen 101 can send control instructions to the control circuit board 104 by touching the corresponding function of the screen, and the control circuit board 104 is used to be connected to the display circuit board 201.
[0042] In the above implementation process, a large color serial port screen 101 is provided on the tooling base plate 10. The tester can input control instructions through the large color serial port screen 101 to control the screen of the LCD screen, which is convenient for observing the test screen and is conducive to switching the screen, avoiding the outflow of defective products due to unclear observation, thereby improving the test quality. At the same time, the fixed mounting plate 20 is flipped relative to the tooling base plate 10 to facilitate the replacement of the display circuit board 201, thereby testing LCD screens of different sizes.
[0043] In some embodiments, the test fixture further includes a support frame 102, which is connected to the large color serial port screen 101 and the tooling base plate 10.

[0044] In the above implementation process, the large color serial port screen 101 is fixed to the tooling base plate 10 through the support frame 102, thereby fixing the large color serial port screen 101, making it convenient for testers to input control commands, facilitating screen switching, avoiding the outflow of defective products due to unclear observation, and improving test quality.
[0045] Please refer to Figure 1 and Figure 2 The test tool also includes a top plate 103, which is connected to the tool base plate 10, and is located on the side of the tool base plate 10 close to the large color serial port screen 101, so that when the fixed mounting plate 20 is flipped relative to the tool base plate 10, the top plate 103 abuts against the fixed mounting plate 20.

[0048] In some embodiments, the test fixture further includes a control circuit board 104 , which is fixed to the fixture base plate 10 , and the control circuit board 104 is respectively connected to the large color serial port screen 101 and the display circuit board 201 .

[0052] In some embodiments, the test fixture further includes a power interface 106 , which is connected to the control circuit board 104 for inputting power.
[0053] In some embodiments, the fixed mounting plate 20 is configured with a plurality of through holes 203, and the plurality of through holes 203 are spaced apart along a first direction and / or a second direction, wherein the first direction includes a left-right direction, and the second direction includes a front-back direction. The length and diameter of the through holes 203 can be set according to actual conditions, and no specific restrictions are imposed herein.
