[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. Example

[0018] Reference Figure 1 and 2 As shown, in one embodiment of the present invention, a GPU intelligent floating test plug-in module is disclosed, which is used to perform an electrical connection test between a server motherboard and a GPU, including: Support 1, which is used to fix the entire plug-in module; A driving unit, which is disposed on the support 1, and includes a push plate 33 and a motor 31 for driving the push plate 33 to move linearly; The GPU fixing unit 2 is arranged on the support 1. The GPU fixing unit 2 includes a mounting seat 22 and a GPU5 fixedly connected to the mounting seat 22. The GPU5 is located at the bottom of the mounting seat 22. When the push plate 33 pushes the GPU fixing unit 2 down, the pins of the GPU5 are inserted into the GPU interface of the server motherboard to complete the electrical connection. The mounting seat 22 is connected to the push plate 33 by a plurality of high-grade screws. The high-grade screws allow the mounting seat 22 to float relative to the push plate 33 along the direction in which the push plate 33 moves. Due to the error in the interface position of different server motherboards, if the plug-in module cannot accurately insert the GPU5 pin into the motherboard interface, the GPU5 pin will be damaged under the action of the contact force. The buffering of the high-grade screws can avoid the damage of the GPU5 pin, so as to adjust the position of the motherboard interface in time; The pressure sensor 6 is arranged in the gap between the mounting seat 22 and the push plate 33, and is used to detect the force between the mounting seat 22 and the push plate 33 to ensure whether the contact force between the GPU5 pin and the motherboard interface reaches the expected value. If the value of the pressure sensor 6 reaches the preset expectation, it is fed back to the motor 31 to control the push plate 33 to stop moving.

[0019] Reference Figure 1 As shown, it also includes a position sensor 4 arranged on the support 1, and the position sensor 4 is used to detect the position of the push plate 33 to ensure that the push plate 33 is at the origin position before pushing the GPU fixing unit 2 each time. Specifically, the position sensor 4 is preferably a photoelectric sensor, and a baffle is fixedly provided on the push plate 33. When the baffle moves to the origin position, it is detected by the photoelectric sensor.

[0020] Reference Figure 1 As shown, the driving unit also includes a connecting plate 3, which is connected to the output end of the motor 31. In order to ensure the precise and smooth movement of the push plate 33, the connecting plate 3 and the push plate 33 are fixedly connected by a guide column 32. The support 1 is provided with a guide hole, and the guide column 32 is slidably connected to the guide hole.

[0021] Reference Figure 1 As shown, four guide posts 32 are further included. The four guide posts 32 are distributed in an array. Accordingly, the support 1 is provided with four guide holes corresponding to the four guide posts 32 .

[0022] Reference Figure 1As shown, it also includes two hard pads 34 arranged in the gap between the push plate 33 and the mounting seat 22, and the two pads 34 are arranged on both sides of the pressure sensor 6, wherein the pad is fixedly connected to the push plate 33, and each of the pads 34 is connected to the mounting seat 22 by at least three of the high-grade screws, and the three high-grade screws are evenly distributed along the length direction of the pad.

[0023] Reference Figure 3 As shown, the GPU fixing unit 2 also includes two guide rods 21, and the two guide rods 21 are arranged on both sides of the GPU5. The guide rods 21 are arranged parallel to the moving direction of the GPU5, and the ends of the guide rods 21 are arranged lower than the GPU5. When the GPU fixing unit 2 is pressed down, the guide rods 21 are used to cooperate with the server motherboard to roughly position the GPU5.

[0024] Reference Figure 3 As shown, since the GPU5 continuously generates heat during the test, in order to accelerate the heat dissipation effect, the GPU fixing unit 2 also includes a heat dissipation component, which is arranged on the mounting seat 22 and located above the GPU5 for dissipating heat. More specifically, the heat dissipation component includes a plurality of heat sinks 27 arranged in parallel and a heat dissipation fan 26 aligned with the heat sink 27 from the top. The heat sink 27 is used to conduct the heat generated by the GPU5, and the heat dissipation fan 26 blows air into the gaps between adjacent heat sinks 27 to accelerate air flow.

[0025] Reference Figure 3 As shown, the GPU fixing unit 2 also includes a mounting plate 25 arranged above the GPU 5, and the mounting plate 25 is movably connected to the mounting seat 22 through a plurality of spring 24 components, and the plurality of spring 24 components are distributed in an array, and the heat sink 27 of the heat dissipation component is arranged on the mounting plate 25, and the spring 24 component is used to buffer the mounting plate 25 and the heat dissipation component.

[0026] Reference Figure 3 As shown, the spring 24 assembly and the GPU5 are respectively arranged on different sides of the mounting plate 25, and the spring 24 assembly includes a bolt 23 and a spring 24 sleeved outside the bolt 23, the bolt 23 is parallel to the guide rod 21, one end of the spring 24 abuts against the nut of the bolt 23, and the other end of the spring 24 abuts against the mounting plate 25, wherein one end of the bolt 23 passes through the through hole of the mounting plate 25 and is threadedly connected to the mounting seat 22; in other embodiments, the two ends of the spring can be fixedly connected to the nut and the mounting plate respectively.

[0027] Furthermore, each pad strip 34 is connected to the mounting base 22 via three high-end screws, and the six high-end screws are distributed in an array.

[0028] Furthermore, the mounting base 22 includes a plurality of parallel and spaced-apart flat plates, and adjacent flat plates are fixedly connected via four connecting columns distributed in an array, wherein the pad 34 is connected to the topmost flat plate, and the heat dissipation assembly and the GPU are respectively connected to the remaining flat plates.

[0029] The working principle of the GPU intelligent floating test plug-in module described in the present invention is: Fix GPU5 on the mounting base 22, fix the GPU5 rotating plate to GPU5, and then fix the GPU5 rotating plate tightly through the rotating plate fixing plate. First, detect the position of the push plate 33 through the position sensor 4 to ensure that the position of the push plate 33 is correct. After the server motherboard arrives at the test station, the motor 31 presses down the GPU fixing unit 2 through the push plate 33, so that the pins of GPU5 are automatically inserted into the GPU interface of the motherboard. If the pins of GPU5 cannot be accurately inserted into the motherboard interface, the GPU fixing unit 2 floats relative to the push plate 33, thereby avoiding the GPU5 pins from being crushed until the GPU5 pins are successfully inserted into the motherboard interface; when the pressure sensor 6 detects that the contact force reaches the expected value, the push plate 33 stops pressing down, and the GPU5 pins are well electrically connected to the motherboard interface. After the detection is completed, the motor 31 lifts the GPU fixing unit 2, and the GPU5 pins are automatically pulled out of the motherboard interface.

[0030] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
