Abstract
Description
Technical Field
[0001] This utility model relates to the field of display screen testing, specifically a display screen aging test device. Background Technology
[0002] Screen light leakage is caused by poor sealing between the screen and the back panel frame, malfunction, or aging, resulting in light emanating from the screen edges and causing localized whitening of the LCD panel on a solid color background.
[0003] Existing display screen testing devices generally suffer from the following problems:
[0004] The testing process requires manual adjustment of the display screen's orientation, which is inefficient.
[0005] The power supply structure is complex, and rotation can easily lead to wire tangling or poor contact.
[0006] The low degree of modularity makes maintenance and component replacement difficult. To address these shortcomings, there is an urgent need for a display screen testing device that can rotate automatically, has a stable power supply, and is easy to assemble.
[0007] However, the traditional display screen aging test device currently on the market has an insufficiently optimized structure and an unreasonable design. Utility Model Content
[0008] The purpose of this invention is to provide a display screen aging test device to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A display screen aging test device includes a support frame, a support plate fixedly connected to the top of the support frame, a top plate installed at the center of the support plate, mounting seats installed on the upper side of the top plate, a connecting shaft installed at the center of the top plate, a clamp fixedly connected to the outer side of the upper surface of the connecting shaft, and a display screen body installed at the clamping part of the clamp.
[0011] As a further improvement of this utility model: a fixing pin is provided between the connecting shaft and the second mounting base, and the number of fixing pins is five sets, and the five sets of fixing pins are structurally compatible.
[0012] As a further embodiment of this utility model: a support frame is fixedly connected to the bottom center of the support plate, and a mounting bracket is fixedly connected to the bottom of the support frame. A motor is fixedly connected to the upper surface of the mounting bracket. A drive shaft is rotatably connected to the drive end of the motor. A driven shaft is connected to the outer wall of the drive shaft via a belt drive. A worm gear is installed at one end of the driven shaft.
[0013] As a further embodiment of this utility model: springs are fixedly connected to the lower outer surface of the outer wall of the top plate near the outer side, and a push rod is fixedly connected to the bottom of the spring, with a cylinder provided on the inner side of the push rod.
[0014] As a further embodiment of this utility model: the top of the spring penetrates the bottom of the support plate and is fixedly connected to a top seat, the top of the top seat is equipped with an mounting plate, and the upper surface of the mounting plate is equipped with a conductive platform.
[0015] As a further improvement of this utility model: the upper surface of the mounting plate is provided with perforations on both the left and right sides, and the number of perforations is four sets, with the four sets of perforations having a matching size.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model features a dual-axis motor-driven system that enables omnidirectional rotation of the display screen, covering multi-angle testing needs. Springs press against the conductive platform and mounting plate to eliminate contact gaps during rotation and prevent power outages. Components are assembled via plug-in and snap-fit methods, making disassembly and maintenance simple. Multi-directional testing can be completed with a single installation, improving testing efficiency. The clamping structure allows for adjustable clamping force to adapt to different display screen sizes, resulting in a more optimized structure and a more rational design.
[0018] In this utility model, a cylinder installed between the support plate and the top plate is used to fix the push rod, which is connected to a spring. The spring connects to the top seat, and the mounting plate fixed to the top of the top seat cooperates with the conductive platform to transmit electrical energy. By connecting the wire to the conductive platform and the display screen body, it is possible to energize the display screen body at different positions. Attached Figure Description
