[0002] A power supply module is a power supply that can be directly mounted on a printed circuit board. Its features include the ability to provide power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field-programmable gate arrays (FPGAs), and other digital or analog loads.

[0003] In the existing technology, in order to ensure the production quality of power modules, it is necessary to conduct factory testing on the power modules. Since the testing process is in a live state, it is necessary to ensure the safety of the testing workers. Therefore, an intelligent testing device for power modules is needed to meet people's needs. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A power module intelligent testing device includes a base plate 100. Two positioning clamps 101 are fixedly installed on the top side of the base plate 100, and a test plate 102 is fixedly installed between the two positioning clamps 101. A connection slot 103 is fixedly installed on the test plate 102. A mounting bracket 200 and a visual detection unit 104 are fixedly installed on the base plate 100. Two movable arms 201 are slidably installed on the mounting bracket 200, and a sealing cover 202 is fixedly installed on the two movable arms 201. A test start switch 203 is fixedly installed on the sealing cover 202. The positioning clamps 101 are used to initially fix the power module, and the movable sealing cover 202 is used to cover the positioning clamps 101 to achieve the sealing and isolation of the live parts. At the same time, the positioning clamps 101, together with the pressure plate 207, fix the position of the power module to prevent it from moving during the test, which could lead to poor contact and achieve safe testing of the power module.

[0022] In an optional embodiment: a handle 204 is fixedly installed on the side of the enclosure 202, and a control switch 205 is fixedly installed on the handle 204.

[0023] It should be noted that the handle 204 and the control switch 205 are used to control the descent of the enclosure 202, and the handle 204 controls the start of the drive motor 303.

[0024] In an optional embodiment: a compression spring 206 is fixedly installed on the nickel coin of the enclosure 202, and a pressure plate 207 is fixedly installed on the bottom end of the compression spring 206.

[0025] It should be noted that the pressure plate 207 makes full contact with the power module under the compression of the pressure spring 206, ensuring that the pins of the power module are stably connected to the connection slot 103.

[0026] In an optional embodiment: a camera mounting bracket 208 is fixedly mounted on the side of the mounting bracket 200, and a camera 209 is fixedly mounted on the camera mounting bracket 208.

[0027] It should be noted that before testing, the identification code of the power module will be recorded using camera 209 to avoid missed detection.

[0028] In an optional embodiment: the mounting frame 200 has a lifting groove 300, a lifting block 301 is slidably installed in the lifting groove 300, the lifting block 301 is fixedly installed on the movable arm 201, and two limiting slide rods 302 are fixedly installed on the inner wall of the lifting groove 300, the two limiting slide rods 302 passing through the lifting block 301.

[0029] In an optional embodiment: a drive motor 303 is fixedly installed at the top of the mounting bracket 200, a lead screw 304 is fixedly installed at the output end of the drive motor 303, and a threaded hole 305 is opened on the lifting block 301, and the lead screw 304 is threadedly installed in the threaded hole 305.

[0030] It should be noted that the output end of the drive motor 303 drives the lead screw 304 to rotate. The rotating lead screw 304 drives the lifting block 301 to slide in the lifting groove 300 through the threaded hole 305. The movable lifting block 301 is restricted by the limit slide rod 302 to maintain stability during the lifting process.

[0031] In an optional embodiment, four anti-slip feet 105 are fixedly installed on the bottom side of the base plate 100.

[0032] Working principle of this utility model:

[0033] When using this device, the power module must first be placed between the two positioning clamps 101. Because the position of the power module is defined by the positioning clamps 101, the pins on the power module can be directly and accurately connected to the connection slot 103. At this point, the handle 204 and control switch 205 can be used to control the descent of the enclosure 202. The handle 204 controls the start of the drive motor 303, and the output of the drive motor 303 drives the lead screw 304 to rotate. The rotating lead screw 304 drives the lifting block 301 to slide within the lifting groove 300 through the threaded hole 305. The lifting block 301 is limited by the limiting slide bar 302 to maintain stability during the lifting process. The movable lifting block 301 drives the closed cover 202 to move through the movable arm 201. After the closed cover 202 is lowered, it can completely cover the positioning clamp 101, thereby achieving the function of isolating the live parts. At the same time, the pressure plate 207 is fully in contact with the power module under the compression of the compression spring 206, ensuring that the pins of the power module are stably connected to the connection slot 103. Before the test, the identification code of the power module will be recorded by the camera 209 to avoid missed detection.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
