Description

Technical Field

[0001] This utility model relates to the field of graphics card testing, and in particular to a multi-specification universal graphics card testing fixture. Background Technology

[0002] In the field of computer hardware, multi-specification general-purpose graphics cards are products developed to meet diverse market demands. These graphics cards break the limitations of traditional graphics cards with single specifications. Their interface design is compatible with multiple motherboard interface standards, and they also have a variety of configuration options for memory capacity, heat dissipation modules, and power supply interfaces. They can adapt to desktops and workstations with different performance requirements, becoming key hardware for improving the flexibility and compatibility of devices.

[0003] In the current manufacturing process of multi-specification universal graphics cards, graphics card performance testing is a crucial step in ensuring product quality. However, current graphics card testing fixtures cannot fit tightly to the graphics card when testing different specifications of universal graphics cards, which can easily lead to poor contact. This unstable fixing state will affect the accuracy of test data. Therefore, we propose a multi-specification universal graphics card testing fixture to solve the above problems.

[0022] Please see Figure 1-4 In this utility model, a multi-specification universal graphics card testing fixture includes a test platform 1, a support box 2 fixedly installed on the bottom surface of the test platform 1, lifting devices 3 fixedly embedded on both sides of the test platform 1, a test seat 9 fixedly installed on the upper surface of the test platform 1, a graphics card socket 10 opened on the upper surface of the test seat 9, a positioning pressing component 4 provided above the test platform 1, a support plate 5 fixedly embedded on the back of the test platform 1, a display screen 7 and a touch panel 6 fixedly embedded on one side of the support plate 5, a main control circuit board 8 fixedly installed on the inner bottom wall of the support box 2, and the positioning pressing component 4 includes a lifting support plate 401, and a positioning pressure plate 406 provided below the lifting support plate 401.

[0023] In this embodiment: the lifting device 3 drives the positioning pressing component 4 to move downward, which enables the positioning pressure plate 406 to make close contact with the top of the graphics card and perform downward positioning. Compared with traditional fixtures, it can achieve adaptive close fit according to the size and shape of different graphics cards, thus improving the stability of the test.

[0024] As a technical optimization of this utility model, a sensor cover 402 is fixedly embedded on the upper surface of the lifting support plate 401. A pressure sensor 405 is fixedly installed on the inner top wall of the sensor cover 402. The detection end of the pressure sensor 405 is fixedly installed on one side of the positioning plate 406. The pressure sensor 405 is electrically connected to the touch panel 6 through a wire. Two sliding holes 403 are opened on one side of the lifting support plate 401. Sliding rods 404 are slidably connected to the inner walls of the two sliding holes 403. The bottom ends of the two sliding rods 404 are fixedly installed on the upper surface of the positioning plate 406.

[0025] In this embodiment: the sliding engagement of the sliding hole 403 and the sliding rod 404 ensures the stability and accuracy of the positioning plate 406 during the pressing process. In addition, when the positioning plate 406 is pressed down, it can contact the top of the test graphics card. The pressure sensor 405 monitors the pressure of the positioning plate 406 on the graphics card in real time and transmits the pressure data to the touch panel 6 through the wire. If the pressure data does not reach the appropriate range, the user can readjust the electric cylinder 303 through the touch panel 6 to ensure that the graphics card is tightly attached.

[0026] As a technical optimization of this utility model, both lifting devices 3 include a support cover 301 fixedly embedded on the outer surface of the test platform 1. An electric cylinder 303 is fixedly installed on the inner bottom wall of both support covers 301. A lifting slide plate 302 is fixedly installed on the telescopic end of both electric cylinders 303. The side of the two lifting slide plates 302 that are close to each other is fixedly connected to the outer surface of the lifting support plate 401.

[0027] In this embodiment: the extension end of the electric cylinder 303 drives the lifting slide plate 302 to move, which in turn pushes the lifting support plate 401 to move up and down. The downward movement of the lifting support plate 401 enables the positioning pressure plate 406 to press down and fix the test graphics card. In addition, the bottom of the positioning pressure plate 406 is provided with a rubber buffer layer to avoid squeezing and damaging the test graphics card.

[0028] As a technical optimization of this utility model, the outer surface of the support box 2 is provided with a wire hole 12, the bottom surface of the test platform 1 is provided with a through hole 11, the through hole 11 is located below the test seat 9, the touch panel 6 is electrically connected to the electric cylinder 303 through wires, the test seat 9 is electrically connected to the main control circuit board 8 through wires, and the main control circuit board 8 is electrically connected to the display screen 7 and the touch panel 6 through wires respectively.

[0029] In this embodiment: the through hole 12 provides a channel for connecting external power cables, data cables, etc., to the inside of the fixture; the through hole 11 is used for wiring between the test base 9 and the main control circuit board 8 inside the support box 2; the touch panel 6 is electrically connected to the electric cylinder 303 through wires, realizing remote control of the lifting device 3; the user inputs commands on the touch panel 6, and the electrical signal is transmitted to the electric cylinder 303 through wires, controlling the extension and retraction of the electric cylinder 303; the test base 9 is electrically connected to the main control circuit board 8 through wires, serving as a bridge for signal transmission between the graphics card and the test circuit; the main control circuit board 8 is electrically connected to the display screen 7 and the touch panel 6 through wires, playing a core role in data processing and interaction; the main control circuit board 8 transmits the data obtained from testing the graphics card to the display screen 7 through wires, presenting it to the user in a visual form; at the same time, the user can also send operation commands to the main control circuit board 8 through the touch panel 6, such as selecting test items and adjusting test parameters.

[0030] The working principle of this utility model is as follows: When in use, the graphics card to be tested is inserted into the graphics card socket 10 above the test socket 9. Then, the user issues a command through the touch panel 6, and the two lifting devices 3 retract, which can drive the positioning pressing device 4 to move downward until the positioning pressure plate 406 contacts the top of the graphics card to press it down and position it. After the graphics card is stably fixed, the main control circuit board 8 performs a performance test on the graphics card and transmits the test data to the display screen 7 for display. At the same time, the user can also operate and view relevant test information on the touch panel 6, which makes it easy for the user to intuitively obtain the graphics card performance test results, thereby ensuring the accuracy of the test data.

[0031] However, the above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
