In order to improve the accuracy of checking the display screen by manual observation, the carrying platform carrying the display screen is usually set at an inclination relative to the horizontal plane, so that when the display screen is placed on the carrying table, the line of sight of the operator can be kept vertical or nearly vertical to the surface of the display screen . However, due to individual differences among different operators, such as different heights, different operators may observe different situations when facing the same loading platform and display screen.

Based on this, in the related art, a base is provided under the inclined bearing platform, and a rotating shaft is connected to the base. The rotating shaft can rotate around the connection point between the base and the rotating shaft, and the lower end of the bearing platform is rotatably connected to the base.

However, the above method can only eliminate errors caused by differences in eye heights of different operators. In the actual operation process, in addition to the difference in the position of the eyes of different operators, there may also be differences in the size of the viewing angle range, that is, the size of the display area that can be observed within the viewing angle range of different operators is different. However, this operation process needs to be completed within a certain range of viewing angles.

Specifically, when checking the uniformity of the display screen, a preset critical angle is usually set, and if an uneven problem is seen when the angle is smaller than the critical angle, it is determined that the display screen is unqualified. For example, if the critical angle is set to 60°, if the uneven problem can be seen at an angle less than 60°, it is judged that the display screen is unqualified; if the uneven problem is not seen at an angle smaller than 60°, it is judged The display is acceptable. Therefore, when the preset critical angle is determined, operators with different viewing angles will get different judgment results when inspecting the same display screen, which is prone to overkill or missed inspections.

In order to solve the above problems, the present application provides a fixture for display screen inspection. By setting the loading table for loading the product to be inspected on the support base, and setting the adjustment assembly on the support base, the adjustment assembly is used to rotate the preset Set the axis to rotate the loading platform, so that the operator can adjust the angle of the loading platform according to the actual situation during the operation, so that the display screen on the loading platform falls within the range of the operator's viewing angle to a moderate size, thereby eliminating the difference in the size of the individual viewing angle range The error brought about improves the accuracy of the inspection.
