Description

Technical Field

[0001] This utility model relates to the field of display motherboard testing technology, and in particular to an automatic testing device for display motherboards. Background Technology

[0002] As a display terminal in modern devices, the operation of a monitor mainly relies on the display motherboard.

[0003] After the monitor motherboard is manufactured, it needs to undergo multiple tests, among which the interface lifespan test is essential. The plug-in / plug-out test is one type of interface lifespan test. In existing technology, this is usually done by moving the plugs fixed on the monitor motherboard interface and rails together. However, this method can only test one interface at a time, making it inconvenient to switch between interfaces when multiple monitor motherboard interfaces need to be tested.

[0004] To address the aforementioned issues, an automatic testing device for monitor motherboards is proposed. Utility Model Content

[0005] In view of this, the present invention addresses the lack of a needle and its main purpose is to provide an automatic testing device for display motherboards, which aims to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic testing device for a display motherboard, comprising a base and a display motherboard mounted on the base, a pneumatic guide rail one and a pneumatic guide rail two respectively mounted on the base, a motor one mounted between the pneumatic guide rail one and the display motherboard, the motor one mounted on the pneumatic guide rail one, a fixed bracket connected to the rotating end of the motor one, and the motor one connected to the display motherboard through the fixed bracket, a motor two mounted on the pneumatic guide rail two, a mounting platform fixedly mounted on the rotating end of the motor two, the mounting platform having several sets of steps arranged in a stepped manner along the circumference, several sets of different plugs can be fixed through the several sets of steps, and several sets of plugs are fixedly mounted on the mounting platform.

[0007] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0008] This device clamps and mounts the monitor motherboard using a fixed bracket. Through the cooperation of pneumatic guide rail one and motor one, the interface on the monitor motherboard that needs to be tested can be adjusted to align with the plug on the mounting platform. Then, pneumatic guide rail two drives motor two and the mounting platform to move towards and away from the monitor motherboard, repeatedly performing plug-in / plug-out tests. By rotating the mounting platform using motor two, the plug on the mounting platform can be adjusted so that the plug to be tested faces the monitor motherboard. Different height steps on the mounting platform allow for testing at different heights. By adjusting motor one on the monitor motherboard, in conjunction with the movement of pneumatic guide rail one, motor one, the fixed bracket, and the monitor motherboard, the position of the connector on the monitor motherboard that needs to be tested can be adjusted, facilitating the adjustment and replacement of the connector to be tested.

[0009] In addition, the PLC controller can be used to programmatically control pneumatic guide rail one, motor one, pneumatic guide rail two, and motor two, reducing manual operation.

[0010] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Please see Figures 1 to 4 This utility model embodiment provides an automatic testing device for a display motherboard, including a base 1 and a display motherboard 4 mounted on the base 1. A pneumatic guide rail 3 and a pneumatic guide rail 5 are respectively mounted on the base 1, arranged vertically. A motor 2 is positioned between the pneumatic guide rail 3 and the display motherboard 4, mounted on the guide rail portion of the pneumatic guide rail 3. The pneumatic guide rail 3 drives the motor 2 to move. A fixed bracket is connected to the rotating end of the motor 2. The display motherboard 4 is specifically mounted on the fixed bracket. The rotation of the motor 2 causes the fixed bracket to rotate. The fixed bracket is a common type of bracket with grippers, which connects to the display motherboard 4. It is important to note that the fixed bracket needs to be located at the axis of the rotating end of the motor 2 to ensure a smooth trajectory when the fixed bracket and the display motherboard 4 rotate.

[0019] Pneumatic guide rail 25 is perpendicular to pneumatic guide rail 13, with pneumatic guide rail 25 pointing to the midpoint of pneumatic guide rail 13. This ensures that the display motherboard 4 is centered in the device. Pneumatic guide rail 25 is equipped with motor 26, specifically motor 26 is mounted on the guide rail part of pneumatic guide rail 25. The rotating end of motor 26 is fixedly mounted with mounting platform 7, and several sets of plugs are installed on mounting platform 7.

[0020] The type of plug can be changed according to the interface that needs to be tested on different monitor motherboards 4. The plug can be fixed on the mounting platform 7 by fixing plate and screws. The fixing plate is a kind of "U" shaped cross section in the prior art. The two ends of the fixing plate can be used to fix screws. The plug needs to be fixed firmly to prevent it from falling off during plugging and unplugging tests.

[0021] The mounting platform 7 has several sets of steps arranged in a circumferential manner. This allows several sets of different plugs to be fixed at different heights to meet the plugging and unplugging needs of interfaces at different heights on different monitor motherboards 4.

[0022] The steps are preferably distributed in six sections, with the thickness of the mounting platform decreasing by 10 percent in each section, thus creating multiple height options.

[0023] In another scenario, the different step heights of mounting platform 7 can also be customized according to the plug requirements of the motherboard 4 of the monitor to be tested.

[0024] In another scenario, the steps don't have to be distributed in stages; there can simply be a height difference between them to prevent a large angle between two usable heights. This can be adjusted according to actual usage needs.

[0025] In addition, the other side of the mounting platform 7 is a smooth plane. By connecting it to the rotating end of the motor 6, several sets of plugs can be installed on it. By rotating the mounting platform 7 driven by the motor 6, plug-in / plug-out tests of the monitor motherboard 4 can be performed at the same height. By changing the types of the several sets of plugs, plug-in / plug-out tests of different types of plugs at the same height can be performed.

[0026] The base 1 is also equipped with a PLC controller 8, which is electrically connected to pneumatic guide rail 3, motor 2, pneumatic guide rail 5 and motor 6. It is used to perform programmed control on pneumatic guide rail 3, motor 2, pneumatic guide rail 5 and motor 6 to meet the needs of automatic testing. The operation mode of the PLC controller 8 is a common method in the existing technology, which will not be described in detail here.

[0027] In summary, when using this device, the monitor motherboard 4 is first clamped and installed using a fixed bracket. Through the cooperation of pneumatic guide rail 3 and motor 2, the interface of the monitor motherboard 4 that needs to be tested can be adjusted to align with the plug on the mounting platform 7. Then, pneumatic guide rail 25 drives motor 26 and the mounting platform 7 to move towards and away from the monitor motherboard 4, repeatedly performing plug-in / plug-out tests. The rotation adjustment of the mounting platform 7 by motor 26 allows adjustment of the plug on the mounting platform 7, ensuring the plug to be tested faces the monitor motherboard 4. Different height steps on the mounting platform 7 allow for testing at different heights. The adjustment of the monitor motherboard 4 by motor 2, combined with the movement of motor 2, the fixed bracket, and the monitor motherboard 4 by pneumatic guide rail 3, allows for adjustment of the position of the connector on the monitor motherboard 4 that needs to be tested. The PLC controller 8 can programmatically control pneumatic guide rail 3, motor 2, pneumatic guide rail 2, and motor 26, reducing manual operation.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
