[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows: Example 1 The specific structure of this embodiment is as follows: Figure 1-Figure 4As shown, a positioning device for testing power electronic equipment comprises: a box body 1, a support leg 2 is arranged at the bottom of the box body 1, two clamping assemblies 4 are arranged inside the box body 1, and a spraying assembly 3 is arranged on the top of the box body 1; the spraying assembly 3 comprises a dosing machine 31 and a gas storage tank 32 arranged on the top of the box body 1, and a spraying assembly is arranged inside the box body 1; the spraying assembly comprises a spray plate 33 arranged inside the box body 1 and a nozzle 34 arranged at the bottom of the spray plate 33, an open groove is opened on the top of the box body 1, a feed pipe 35 is connected between the spray plate 33 and the dosing machine 31, and the feed pipe 35 is in the open groove, and a one-way valve 36 is arranged on the feed pipe 35; the clamping assembly 4 comprises two L-shaped plates 41 arranged on both sides of the moving block 82 and a clamping jaw 42 installed between the two L-shaped plates 41, and an auxiliary assembly 6 is arranged on the clamping jaw 42.

[0024] By adopting the above technical solution: When in use, the electronic device is first placed between the two clamps 42 so that the clamps 42 can clamp the electronic device, which is convenient for positioning the electronic device. Then, when the electronic device needs to be cleaned, the liquid is allowed to flow into the spray plate 33 along the feed pipe 35 through the dosing machine 31. Then, the gas tank 32 pressurizes the spray plate 33 so that the liquid inside the spray plate 33 is sprayed through the nozzle 34 to complete the cleaning of the electronic device, so that the electronic device can complete subsequent processing.

[0025] Example 2 The specific structure of this embodiment is as follows: Figure 1 , Figure 2 and Figure 4 As shown, the adjustment component 8 includes two fixed plates 81 arranged inside the box body 1 and a moving block 82 mounted on the two fixed plates 81, the two moving blocks 82 are hinged with a first linkage plate 85 and a second linkage plate 86, and a first power component is arranged between the first linkage plate 85 and the second linkage plate 86; the first power component includes a receiving groove opened inside the box body 1 and a motor 83 arranged inside the receiving groove, and the motor 83 is provided with a rotating disk 84 hinged to the first linkage plate 85 and the second linkage plate 86.

[0026] By adopting the above technical solution: When in use, the motor 83 first drives the rotating disk 84 to rotate inside the box body 1, so that the rotating disk 84 drives the first linkage plate 85 and the second linkage plate 86 to rotate. Since the first linkage plate 85 and the second linkage plate 86 are hinged with the two moving blocks 82, the moving blocks 82 slide on the fixed plate 81 as the first linkage plate 85 and the second linkage plate 86 rotate, so that the two L-shaped plates 41 and the clamps 42 move at the same time and clamp inward at the same time, which makes it easier for the clamps 42 to clamp and fix the electronic device. The simultaneous movement of the two clamps 42 also makes it easier to remove the electronic device from the clamps 42, thereby increasing the working efficiency of the device.

[0027] Example 3 The specific structure of this embodiment is as follows: Figure 1 , Figure 2 and Figure 6 As shown, the auxiliary component 6 includes an auxiliary plate 61 arranged between two L-shaped plates 41 and a through hole opened on the clamping jaw 42, an auxiliary clamping plate 63 is arranged on one side of the clamping jaw 42, and a second power component is arranged between the clamping jaw 42 and the auxiliary plate 61; the second power component includes an electric push rod 62 arranged between the clamping jaw 42 and the auxiliary plate 61, and one end of the electric push rod 62 close to the clamping jaw 42 passes through the through hole and is connected to the auxiliary clamping plate 63.

[0028] By adopting the above technical solution: When in use, the clamping jaws 42 first clamp the electronic device while pushing the auxiliary clamping plates 63 relative to each other through the two electric push rods 62, so that the two auxiliary clamping plates 63 respectively perform auxiliary clamping on the two sides of the electronic device, which can effectively increase the stability of the clamping and positioning of the electronic device by the clamping jaws 42, so that the shaking of the electronic device during the test is effectively reduced, thereby reducing the errors generated during the test of the electronic device, facilitating the prevention of the electronic device from falling off the clamping jaws 42, and improving the safety of the device.

[0029] Example 4 The specific structure of this embodiment is as follows: Figure 1 , Figure 2 and Figure 7 As shown, a protective component 7 is provided on the auxiliary splint 63, and the protective component 7 includes two sliding grooves opened on the auxiliary splint 63 and a protective pad 71 arranged on one side of the auxiliary splint 63, a connecting rod 72 is provided on one side of the protective pad 71, and the end of the connecting rod 72 away from the protective pad 71 is in the sliding groove, and a reset component is provided in the sliding groove; the reset component includes a reset spring 73 arranged between the connecting rod 72 and the sliding groove, and the reset spring 73 is in the sliding groove.

[0030] By adopting the above technical solution: When the auxiliary splint 63 moves toward the electronic device, the protective pad 71 first contacts the two sides of the electronic device, effectively reducing the damage of the auxiliary splint 63 to the electronic device, so as to facilitate the subsequent processing of the electronic device. When the clamping force of the auxiliary splint 63 is too large, the protective pad 71 pushes the connecting rod 72 to squeeze the reset spring 73, so that the connecting rod 72 slides into the sliding groove, completing the inward movement of the protective pad 71, effectively reducing the buffering of the clamping force of the electronic device, and avoiding damage to the electronic device due to excessive clamping force. Then, when the clamping is completed, the protective pad 71 is reset by using the resilience of the reset spring 73, so as to facilitate the subsequent use of the protective pad 71.

[0031] Example 5 The specific structure of this embodiment is as follows: Figure 1 , Figure 2 and Figure 5 As shown, a collecting assembly 5 is provided at the bottom of the box body 1, and the collecting assembly 5 includes a reflux groove 54 opened around the inside of the box body 1 and a circulation groove 55 opened inside the box body 1, and the circulation groove 55 is connected with the reflux groove 54. A hopper 53 is provided at the bottom of the box body 1, and the hopper 53 is below the circulation groove 55. A collecting box 51 is provided at the bottom of the hopper 53, and a detachable connecting hopper 52 is provided between the collecting box 51 and the hopper 53.

[0032] By adopting the above technical solution: When in use, the cleaned waste liquid flows into the reflux groove 54 through the box body 1, and then the waste liquid flows along the reflux groove 54 to the circulation groove 55, so that the waste liquid flows into the hopper 53 through the circulation groove 55, and further flows into the collecting box 51 through the hopper 53, thereby completing the recovery of the waste liquid, facilitating the secondary utilization of the liquid and reducing the waste of the liquid. Then, by moving the collecting box 51, the collecting box 51 is removed from the connecting bucket 52, thereby completing the disassembly of the collecting box 51 and the hopper 53, so as to facilitate the recovery of the liquid inside the collecting box 51 and the inspection and maintenance of the collecting box 51, so as to increase the service life of the collecting box 51.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
