DETAILED DESCRIPTION

[0017] With reference to the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0018] Embodiment

[0019] Please refer to Figs. 1-3 The utility model provides a technical scheme: display screen pull -out force test is with auxiliary jig, including jig body 100, jig body 100 is by integrated mounting portion 110 and glue portion 120 is composed, the top of mounting portion 110 is equipped with jig positioning pin fixed hole 111, the bottom of glue portion 120 is equipped with 3M adhesive sheet placing groove 121, 3M adhesive sheet placing groove 121 both sides are equipped with 3M adhesive sheet pin fixed hole 122, 3M adhesive sheet placing groove 121 inside places 3M adhesive sheet and with 3M adhesive sheet pin fixed hole 122 inside plug -in pin fixed and is bonded.

[0020] Specifically, when the display screen pull -out force test is needed, the staff first inserts the positioning pin into the fixed hole 111, can quickly and stably install the jig into the test equipment, when testing, the staff inserts the pin into the 3M adhesive sheet pin fixed hole 122, then the staff places the 3M adhesive sheet in the placing groove 121, so that the 3M adhesive sheet and the pin are bonded and stably placed in the 3M adhesive sheet placing groove 121, then the equipment can drive the jig body 100 to move downward and bond with the screen placed inside the screen jig, then the equipment drives the jig body 100 to move upward, and then the pull -out force test of the screen can be realized, so that the test preparation work becomes efficient and convenient, and the traditional complex process of pasting stainless steel ingot is abandoned, which greatly saves time and labor cost.

[0021] In the embodiment, the top end of the mounting portion 110 is provided with a circular-arc chamfer portion 112.

[0022] Specifically, the circular-arc chamfer portion 112 can effectively avoid scratching during installation of the jig body 100 and the equipment, and also facilitates rotation of the jig body 100, making it convenient for the operator to disassemble and assemble the 3M adhesive sheet, and ensuring the practicability of the jig body 100.

[0023] In the embodiment, the cross-sectional size of the mounting portion 110 is smaller than that of the glue portion 120, and both the mounting portion 110 and the glue portion 120 are made of metal material.

[0024] Specifically, the smaller cross-sectional size of the mounting part 110 allows it to precisely fit specific connection points when connected to the testing equipment, avoiding obstruction of installation space due to excessive size and ensuring the compactness and stability of the fixture installation. The metal mounting part 110 and the glue-filling part 120 give the fixture body 100 high structural strength and durability, preventing deformation and damage to the fixture body 100 during frequent pull-out force tests.

[0025] In this embodiment, the inner wall of the 3M film placement slot 121 is provided with a ceramic coating 123.

[0026] Specifically, due to the strong adhesiveness of 3M film, there is a high possibility that the film may stick severely to the tank wall when it is removed. This not only increases the difficulty of removal but may also cause some film to remain on the tank wall, affecting the normal operation of the next test. However, the ceramic coating 123 has good demolding performance, which can greatly reduce the adhesion phenomenon. The staff can easily remove and discard the used 3M film completely, saving a lot of time for subsequent test preparation, improving test efficiency, and ensuring the efficient operation of the display screen pull-out force test.

[0027] In this embodiment, the width of the 3M film pin fixing hole 122 is greater than half the width of the 3M film placement groove 121, and the hole wall of the 3M film pin fixing hole 122 is provided with anti-slip texture 124.

[0028] Specifically, after inserting the pin into the 3M film pin fixing hole 122, the pin is bonded to the 3M film. During the test, the pull-out process exerts a significant force on the 3M film. The anti-slip texture 124 on the hole wall increases the friction between the pin and the 3M film pin fixing hole 122 wall, preventing the pin from loosening or shifting under force. Even under high-frequency, high-intensity pull-out force tests, the fixing hole 122 with anti-slip texture 124 ensures that the pin firmly fixes the 3M film, keeping the 3M film in a stable installation state. This ensures a stable connection between the screen and the fixture during the test, providing a solid guarantee for obtaining accurate and reliable pull-out force test data and effectively promoting the precise implementation of display screen quality testing.

[0029] The contents not described in detail in this description are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
