Embodiment Construction

[0017] In order to make the technical solutions, technical features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] according to Figure 1-Figure 3 , the detection fixture of the display screen backplane is characterized in that: the detection fixture is a hollow structure, and several protrusions 6, depressions 4 and solid parts 5 that cooperate with the backplane 8 are arranged around the detection fixture, and the detection that can move up and down The jig is placed above the rotatable round platform 7 . The protrusion 6 cooperates with the recessed part 3 of the backboard 8 , the said depression 4 cooperates with the raised part 2 of the backboard 8 , and the said solid part 5 cooperates with the hole 1 of the backboard 8 . A number of backboards 8 to be detected are placed on the rotatable round table 7, and several backboards 8 to be detecte...

Abstract

The invention relates to the field of detecting jigs, in particular to a detection jig for back plates of a display screen. The detection jig is characterized in that the detection jig has a hollow structure; the periphery of the detection jig is provided with a plurality of bumps, recesses and solid parts which are matched with the back plates; the detection jig capable of moving upwards and downwards is arranged above a rotatable round table; the bumps are matched with the recesses of the back plates; the recesses are matched with the bumps of the back plates; the solid pats are matched with the holes of the back plates; and a plurality of back plates are arranged on the rotatable round table, and are arranged symmetrically along the circle center of the round table. Due to the adoption of the detection jig, the entire detection process is simple and convenient; and the detection jig is suitable for batch detection of back plates.

Description

technical field [0001] The invention relates to the field of testing fixtures, in particular to a testing fixture for a display screen backplane. [0002] Background technique [0003] The display backplane is an important part of the display. After the stamping is completed, the display backplane needs to be tested to see if it is qualified. Measuring the size of the backplane and whether the size is qualified by the detection device is mainly achieved by measuring the length, width, and diameter of each side, each surface, and each hole. The measurement process is very complicated and the efficiency is low. [0004] Contents of the invention [0005] The object of the present invention is to overcome the above-mentioned problems, and provide a display backplane testing jig that is convenient for testing the quality of the backplane and can be used for testing multiple backplanes. [0006] In order to achieve the above object, the technical solution adopted in the pre...
