[0025] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] This embodiment provides an automatic testing device for a switching power supply. The automatic testing device for a switching power supply implements automatic testing of the switching power supply without the need for manual auxiliary operations, greatly reducing labor costs, preventing damage to the switching power supply due to human negligence, and improving the testing efficiency and accuracy of the switching power supply.

[0027] Combine Figures 1 to 3 As shown, the automatic testing device for a switching power supply of this embodiment includes an installation unit 10, a testing unit 20, a power tester 30, and a load unit 40. The installation unit 10 installs the switching power supply, and the testing unit 20 cooperates with the power tester 30 and the load unit 40 to test the switching power supply.

[0028] In this embodiment, the automatic testing device for the switching power supply further includes a base plate 50 . The base station 11 , the power tester 30 , and the load device 40 are all mounted on the base plate 50 . The testing unit 20 is connected to the base plate 50 via a bracket 60 .

[0029] Furthermore, a control display screen 70 is provided on the base plate 50. The control display screen 70 is connected to the power tester 30 and the load machine 40 to control and display the test results. When the test unit 20 tests the switching power supply, the operator controls it through the control display screen 70. After the test is completed, the test results will be directly displayed on the control display screen 70, thereby facilitating the operator's control and improving the test efficiency.

[0030] Combine Figure 1 and Figure 3 As shown, the mounting portion 10 of this embodiment includes a base 11, a limiting seat 12, a side stopper 13 and a rotating stopper 14. The switching power supply is placed on the surface of the base 11, and the limiting seat 12, the side stopper 13 and the rotating stopper 14 block and limit the switching power supply. The limiting seat 12 and the side stopper 13 of this embodiment are both installed on the surface of the base 11 to limit and block the switching power supply, and the rotating stopper 14 is connected to the side stopper 13 through the rotating shaft 80. After the switching power supply is rotated and placed, the rotating stopper 14 rotates to block the switching power supply. When the switching power supply test is completed, the rotating stopper 14 is reset so that the switching power supply can be taken out and replaced. Therefore, under the rotation action of the rotating stopper 14, the switching power supply can be quickly limited and replaced, thereby improving the test efficiency.

[0031] In this embodiment, a lower stopper 90 is provided on the base 11 to block the bottom of the switching power supply. The lower stopper 90 can cooperate with the mounting portion 10 to further block and limit the switching power supply, thereby improving the limiting effect of the switching power supply.

[0032] Combine Figure 1 and Figure 2 As shown, the test section 20 of this embodiment includes a test driver 21 and a test probe 22. The test driver 21 drives the test probe 22. After the test probe 22 contacts the switching power supply, the switching power supply is tested. The power tester 30 is connected to one test probe 22 to test the switching power supply. The load machine 40 is connected to another test probe 22 to test the switching power supply. The test driver 21 of this embodiment drives the test probe 22 to contact the switching power supply. Then the power tester 30 tests the power of the switching power supply, and the load machine 40 tests the load of the switching power supply. The test results will be directly displayed on the control display screen 70.

[0033] In this embodiment, the test driver 21 is a cylinder, and the test probe 22 is connected to the test driver 21 via a connecting block 100 .

[0034] In actual use, the automatic testing device for a switching power supply of this embodiment is configured to place the switching power supply on the mounting portion 10. The mounting portion 10 then blocks and limits the switching power supply. The test driver 21 of the testing portion 20 then drives the test probe 22, causing the test probe 22 to contact the switching power supply. The power tester 30 then tests the power of the switching power supply, while the load meter 40 tests the load of the switching power supply. The test results are then displayed directly on the control display 70.

[0035] In summary, the automatic testing device for a switching power supply in this embodiment realizes automatic testing of the switching power supply without the need for manual auxiliary operations, greatly reducing labor costs, preventing damage to the switching power supply due to human negligence, and improving the testing efficiency and accuracy of the switching power supply.
