The base frame 100 is provided with a testing platform 120, on which multiple testing stations 130 are provided. The multiple testing stations 130 are arranged side by side along the length direction of the testing platform 120. Each testing station 130 is provided with an electrical connection component 500. The testing station 130 is used to place a switching power supply 600. The switching power supply 600 can be connected to the electrical connection component 500. The power performance testing module 200 is connected to the electrical connection component 500 to test each switching power supply 600. The laser marking module 300 is used to mark the housing of the switching power supply 600. The displacement driving module 400 is disposed on the base frame 100. The displacement driving module 400 is connected to the laser marking module 300 so that it can drive the laser marking module 300 to pass sequentially along the length direction of the test platform 120 to the positions corresponding to each of the test stations 130.

[0029] The base frame 100 can be made of rods or plates made of alloy or plastic, and the test platform 120 can be rectangular or have a certain length to accommodate each test station 130 on its upper surface.

[0030] The power performance testing module 200 can be a conventional power testing fixture, which can be integrated inside the testing platform 120 or placed on one side of the testing platform 120. In some embodiments of this utility model, such as... Figure 4As shown, the power performance test module 200 includes a signal generation module 210, a power supply module 220, multiple performance detection modules 230, a processing module 240, and a display module 250.

[0033] This utility model relates to an integrated testing and marking device for switching power supplies. Each switching power supply 600 is placed in a corresponding testing station 130, and each 600 is connected to a power performance testing module 200 via an electrical connection component 500. The power performance testing module 200 can perform performance tests on each switching power supply 600. During the testing process, a laser marking module 300 can mark the casing of each switching power supply 600 sequentially. A displacement drive module 400 moves the laser marking module 300 along the length of the testing platform 120, thus passing through the corresponding positions in each testing station 130. This design fully utilizes the time that the power performance testing module 200 spends testing each switching power supply 600 to mark the casing of each switching power supply 600. This design can automatically perform marking while conducting performance testing, saving production time, improving production efficiency, and reducing production costs.

[0034] In some embodiments of this utility model, such as Figure 1 , 2 As shown, the base frame 100 is provided with a bracket 110, which is located above each of the test stations 130. The displacement drive module 400 is disposed on the bracket 110. The displacement drive module 400 can drive the laser marking module 300 to pass sequentially above each of the test stations 130. The displacement drive module 400 drives the laser marking module 300 to move above each test station 130, which can mark the upper surface of the housing of the switching power supply 600.

[0035] In some embodiments of this utility model, the displacement driving module 400 includes a transverse driving component 410, a longitudinal adjustment component 420, and a height adjustment component 430. The transverse driving component 410 is disposed on the bracket 110. The transverse driving component 410 is connected to the longitudinal adjustment component 420 to drive the longitudinal adjustment component 420 to move along the length direction of the test platform 120. The longitudinal adjustment component 420 is connected to the height adjustment component 430 to adjust the position of the height adjustment component 430 in the width direction of the test platform 120. The height adjustment component 430 is connected to the laser marking module 300 to adjust the position of the laser marking module 300 in the height direction.

[0036] The transverse drive component 410 enables the laser marking module 300 to move along the length of the test platform 120, thereby marking each switching power supply 600 sequentially. The longitudinal adjustment component 420 adjusts the position of the laser marking module 300 in the width direction of the test platform 120 during installation, thereby adjusting the position where the laser marking module 300 marks the label on the housing of the switching power supply 600.

[0038] The driving component 415 can be a motor or a rotary cylinder, etc. The driving component 415 drives the first lead screw 412 to rotate. The first lead screw nut 413 is sleeved on the first lead screw 412 through a threaded structure. When the first lead screw 412 rotates, the first lead screw nut 413 can move along the transverse guide rail 411.

[0039] In some embodiments of this utility model, the longitudinal adjustment component 420 includes a longitudinal guide rail 421, a second lead screw 422, a second lead screw nut 423, a second movable seat 424, and a first control member 425.

The height adjustment component 430 is disposed on the second movable seat 424. The second lead screw nut 423 is connected to the second movable seat 424 and is rotatably sleeved on the second lead screw 422. The first control member 425 is connected to the second lead screw 422 so as to be driven to rotate the second lead screw 422.

[0040] The first control element 425 can be a rotating disk, lever, or similar device that is easy for the user to operate. When the user operates the first control element 425, the second lead screw 422 can be rotated by the first control element 425. The second lead screw nut 423 is threaded onto the second lead screw 422. When the second lead screw 422 rotates, the second lead screw nut 423 can move along the longitudinal guide rail 421, thereby changing the installation position of the laser marking module 300 in the width direction of the test platform 120.

[0041] In some embodiments of this utility model, the height adjustment component 430 includes a vertical guide rail 431, a third lead screw 432, a third lead screw nut 433, a third movable seat 434, and a second control member 435.

The first control member 425 is connected to the second lead screw 422 so as to be driven to rotate the second lead screw 422.

[0042] Similarly, the second control element 435 can be a rotating disk, rocker arm, etc., which is easy for the user to operate. When the user operates the second control element 435, the third lead screw 432 can be rotated through the second control element 435.

The cylinder drives the corresponding movable seat to achieve displacement drive of the relevant components through the push rod.

[0044] In some embodiments of this utility model, the test station 130 includes a limiting groove disposed on the test platform 120.

[0045] Each switching power supply 600 can be placed on the limiting groove one by one, thereby limiting the position of the switching power supply 600, preventing the switching power supply 600 from shifting, and improving the marking effect.

[0046] In some embodiments of this utility model, the electrical connection component 500 includes an electrical connection socket located at the end of the limiting groove. The electrical connection socket can be a conventional two-prong socket, three-prong socket, USB socket, etc. The power supply module 220 and signal generation module 210 in the power performance test module 200 simulate external power supply, and then supply power to the switching power supply 600 through the electrical connection socket.

[0047] In some embodiments of this utility model, the laser marking module 300 includes a plurality of laser marking emitters 310, which are arranged side by side along the length of the test platform 120.
