Technical Field

[0001] This invention relates to the field of display screen testing technology, and in particular to a display screen aging test device with a quick-release structure. Background Technology

[0002] Display screen aging refers to the performance degradation of a display due to long-term use or specific conditions. It manifests as reduced brightness, color distortion, decreased contrast, and screen burn-in. Essentially, it is the result of the natural degradation of the screen material. It is mainly divided into two mechanisms: LCD screen aging and LED screen aging. Display screen aging test equipment is a special device that accelerates the degradation of display screen materials and performance by simulating extreme environmental conditions such as high temperature, high humidity, and light. Its main function is to expose potential defects in advance and verify product reliability.

[0003] Traditional display screen aging test devices use a rigid welded frame and bolt-locking structure. Their poor size compatibility means that changing screen models requires disassembling and reassembling a large number of bolts. The one-piece welded frame has non-adjustable slot spacing, affecting overall adaptability. The bolt-pressed probe modules are prone to loosening under equipment vibration, causing poor contact. Power and signal lines need to be repeatedly manually plugged and unplugged, resulting in mechanical wear and electrical damage to the terminals, affecting the overall test results. Therefore, a display screen aging test device with a quick-release structure can be designed. Summary of the Invention

[0004] To overcome the problems of traditional display screen aging test devices, such as the one-piece welded frame, the non-adjustable slot spacing, and the need for repeated manual plugging and unplugging of power and signal cables, which leads to mechanical wear and electrical damage to the terminals and affects the overall test results.

[0005] The technical solution of the present invention is as follows: a display screen aging test device with a quick-release structure, comprising a test box for testing the display screen under light aging, a bottom cover fixed to the bottom of the test box to maintain overall stability, a test platform for placing the display screen for testing operations above the bottom cover, an adjusting guide arm for protecting the display screen and guiding the test cables near the four edges of the test platform, and a first quick-release box and a second quick-release box for quick-release installation of different test equipment and cables interleaved around the outer perimeter of the test platform, and a number of pressure measuring components for gradient pressure testing of the display screen are arranged horizontally on the second quick-release box.

The cylinder drives the guide rod to move the slide along the slide groove. A floating sleeve is provided inside the first quick-release box. Several sets of first quick-release posts are fixed horizontally to the side of the floating sleeve facing the test platform. A first tension plate is fixed to the side of the floating sleeve away from the first quick-release posts. A first quick-release bolt is provided in the center of the first tension plate.

The guide arm 4 is automatically deflected by the steering rod 405 (the angle is calibrated by the scale dial 406). Depending on the size of the display screen, different adaptive clamping and positioning structures are mounted through the mounting hole 302. The first quick-release bolt 508 drives the first tension plate 507, which in turn moves the floating sleeve and the first quick-release post 509 for quick-release adjustment. The second quick-release bolt 603 drives the second tension plate 602, which in turn moves the floating sleeve and the second quick-release post 601 for quick-release adjustment. The position of the floating sleeve is adjusted so that the first quick-release post 509 and the second quick-release post 601 are aligned with the insertion hole 303 of the test bench 3. The cylinder 506 of the first quick-release box 5 drives the guide rod, which moves the slide table 502 along the slide groove 511, so that the test guide tube 504 (with built-in magnetic floating test plug 512) on the tripod 501 is aligned with the wire hole 403 of the adjustment guide arm 4.
