[0033] Specifically, by placing the switch power supply circuit board to be tested on the surface of the test plate 406, and then driving the test box 3 to move by the moving mechanism 2, the transmission gear disc 402 and the transmission rack 401 are engaged for transmission, the transmission gear disc 402 will rotate, and at the same time, the transmission gear disc 402 will drive the bidirectional screw rod 403 to rotate in the opposite direction, and the two sets of transmission blocks 404 will drive away from each other on the outside of the bidirectional screw rod 403, and the connecting rod 405 will rotate and drive the test plate 406 and the switch power supply circuit board on its top to be retracted into the interior of the test box 3 for fixation, so that the later detection mechanism 6 can check the switch power supply circuit. The detection mechanism 6 is used to detect the switching power supply circuit board to be detected. When the switching power supply circuit board to be detected is located directly under the detection mechanism 6, the detection mechanism 6 can work to detect the switching power supply circuit board on the surface of the detection plate 406. When the moving mechanism 2 drives the detection box 3 to reset, the transmission rack 401 moves the bidirectional screw rod 403 to rotate forward, and the two sets of transmission blocks 404 will be driven closer to each other on the outside of the bidirectional screw rod 403. The connecting rod 405 rotates and drives the detection plate 406 and the switching power supply circuit board on its top to move from the inside of the detection box 3, so as to facilitate the workers to unload the switching power supply circuit board after the inspection is completed.

[0034] Please refer to Figure 5 The moving mechanism 2 includes a support base 202 fixed inside the chassis 1, the support base 202 is used to support the motor 201 and the detection box 3, the motor 201 is installed at one end of the support base 202, and a transmission rod 203 is rotatably installed inside the support base 202, the output end of the motor 201 is connected to one end of the transmission rod 203, and the outer side of the transmission rod 203 is connected to the detection box 3.

[0037] Specifically, in order to drive the switching power supply circuit board to be tested inside the detection box 3 to be located directly below the detection end of the detection mechanism 6 for detection, the motor 201 works, and the output end of the motor 201 will drive the transmission rod 203 to rotate, and then the transmission rod 203 will drive the detection box 3 and the switching power supply circuit board to be tested inside it to be located directly below the detection end of the detection mechanism 6 for detection. When the detection box 3 moves, by contacting the two sets of contact switches 2021, the contact switch 2021 can monitor whether the detection box 3 moves back and forth to the specified position.

[0038] Please refer to Figure 3 A bracket 8 is installed on the side of the transmission rack 401, and a scraping brush 801 is provided near the bottom of the detection box 3.

[0039] Specifically, in order to process the switching power supply circuit board before detection and avoid foreign matter adhering to its surface, thereby reducing the accuracy of the detection results of the switching power supply circuit board by the device, a scraper 801 is laid on the inner top of the bracket 8. When the detection box 3 drives the internal switching power supply circuit board to move under the action of the moving mechanism 2, the surface of the switching power supply circuit board will contact the bottom of the scraper 801. As the switching power supply circuit board moves, the scraper 801 can scrape the surface of the switching power supply circuit board to avoid foreign matter adhering to its surface, which affects the device's later detection results of the switching power supply circuit board, thereby improving the accuracy of the device's detection results of the switching power supply circuit board.

[0040] Please refer to Figure 4 An anti-interference frame 503 is installed internally and movably at the edge of the detection box 3. The anti-interference frame 503 is made of anti-interference material. A push rod 5 is installed at the bottom of the detection plate 406. A push rod 501 is installed internally and movably near the push rod 5 of the detection box 3. A top rod 502 is installed near the bottom end of the push rod 501 of the anti-interference frame 503.

[0041] Specifically, in order to avoid external electromagnetic signals from causing signal interference to the switching power supply circuit board to be detected and affecting its detection results, when the detection plate 406 drives the switching power supply circuit board on the top to move to the inside of the detection box 3, the bottom of the detection plate 406 will drive the push rod 5 to move downward, and the inclined surface at the bottom end of the push rod 5 will push the push rod 501 to move, and the inclined surface at the other end of the push rod 501 will push the push rod 502 to move upward. When the push rod 502 moves upward, it will drive the anti-interference frame 503 to move upward. When the detection mechanism 6 detects the switching power supply circuit board, the anti-interference frame 503 can avoid external electromagnetic signals from causing signal interference to the switching power supply circuit board to be detected, thereby improving the accuracy of its detection results.

[0042] Please refer to Figure 1 and Figure 6 The detection mechanism 6 includes a support frame 601 installed at one end of the chassis 1, the support frame 601 is used to support the telescopic rod 602, the telescopic rod 602 is installed on the side of the support frame 601 close to the anti-interference frame 503, and the detection head 603 is installed on the movable end of the telescopic rod 602.

[0043] Please refer to Figure 1 A comprehensive tester 7 is installed on the outer wall of the chassis 1. The comprehensive tester 7 is electrically connected to the detection head 603. The comprehensive tester 7 is a switching power supply comprehensive tester, which is a device specially used to test the performance of the switching power supply. It can simulate various input and output conditions and perform comprehensive tests on the output voltage, current, power, efficiency, waveform, etc. of the power supply.

[0044] Specifically, in order to detect the switching power supply circuit board, the telescopic rod 602 works, and its moving end drives the detection head 603 to contact the switching power supply circuit board, and then the detected value is sent to the comprehensive tester 7. The comprehensive tester 7 simulates various input and output conditions and performs a comprehensive test on the output voltage, current, power, efficiency, waveform, etc. of the power supply.

[0045] Please refer to Figure 1 and Figure 6 A cover plate 6021 is installed on the outer side of the movable end of the telescopic rod 602 , and an insert block 6022 is provided at the bottom of the cover plate 6021 near the slot 504 .

[0046] Please refer to Figure 3 and Figure 6 Slots 504 are provided inside the surface of the anti-interference frame 503 , and four groups of slots 504 are distributed at the four corners inside the anti-interference frame 503 , and the insert blocks 6022 are located inside the slots 504 .

[0047] Specifically, in order to improve the anti-interference during device detection, when the telescopic rod 602 drives the detection head 603 to contact the switching power supply circuit board, the cover 6021 will be located above the anti-interference frame 503. The cover 6021 and the anti-interference frame 503 will make the periphery of the switching power supply circuit board sealed, which can improve the anti-interference during device detection. At the same time, the plug block 6022 at the bottom of the cover 6021 will be inserted into the interior of the slot 504, which can position the cover 6021 and the anti-interference frame 503, so that the detection head 603 can accurately contact the detection position of the switching power supply circuit board.

[0048] Please refer to Figure 7 The detection head 603 adopts an optical sensor camera, and the detection box 3 adopts a translucent material, such as translucent glass or translucent plastic plate. It also includes a fill light mechanism 9 for supplementing the light of the power circuit board below the detection head 603. The fill light mechanism 9 includes three fixed fill light plates 91 arranged on the front, rear and right sides of the position below the detection head 603. The fixed fill light plate 91 is fixedly connected to the chassis 1. A vertical sliding groove 92 is provided on the rear side of the chassis 1. A movable fill light plate 93 is slidingly provided inside the vertical sliding groove 92. A bracket rod 94 is fixedly installed on the top surface of the chassis 1. A sliding hole 95 is provided on the bracket rod 94 and the right side of the chassis 1.

[0049] Specifically, when the detection box 3 drives the power supply circuit board to move to the bottom of the detection head 603, the three fixed fill light panels 91 can fill light to the power supply circuit board from three angles. At the same time, the movable fill light panel 93 will drop due to gravity, and can fill light to the power supply circuit board from the left side of the power supply circuit board, thereby being able to fill light to the power supply circuit board in all directions, ensuring that the angle and illumination method of the light source can cover all parts of the circuit board, especially for complex circuit boards, to meet multi-angle and multi-directional light illumination to ensure that the optical sensor camera obtains comprehensive detection and improves detection accuracy.

[0050] Example 2

[0051] Comparative Example 1, wherein another embodiment of the present invention is, please refer to Figure 8 , also includes a tension spring 10 arranged below the transmission rack 401, the lower end of the bracket 8 is U-shaped, the lower end of the bracket 8 passes through and is slidably connected to the transmission rack 401, the two ends of the tension spring 10 are respectively fixed to the bottom surface of the transmission rack 401 and the top surface of the lower end of the bracket 8, a pulley 11 is rotatably installed on the outer wall of the detection box 3, the horizontal position of the pulley 11 is lower than the lower end of the bracket 8, the lower end of the bracket 8 is fixed to one end of an elastic rope 12, and the other end of the elastic rope 12 passes around the lower part of the pulley 11 and is fixed to the transmission gear disc 402.

[0052] Specifically, when the detection box 3 drives the power supply circuit board to move downwardly from the detection head 603, the power supply circuit board moves downwardly following the detection plate 406, resulting in the scraping brush 801 being unable to fully contact and clean the entire power supply circuit board. By setting the tension spring 10 and the elastic rope 12, when the detection box 3 moves downwardly from the detection head 603, the transmission gear disc 402 can pull the bracket 8 and the scraping brush 801 downwardly through the elastic rope 12, and the bristles on the scraping brush 801 can descend with the power supply circuit board and can clean the entire power supply circuit board.

[0053] Working principle: The worker places the switching power supply circuit board to be tested on the surface of the test board 406, and then the motor 201 works. The output end of the motor 201 drives the transmission rod 203 to rotate, and the transmission rod 203 drives the test box 3 and the switching power supply circuit board to be tested inside it to move. At this time, the transmission gear plate 402 and the transmission rack 401 are engaged and driven, and the transmission gear plate 402 rotates. At the same time, the transmission gear plate 402 drives the bidirectional screw rod 403 to rotate in the opposite direction. The two sets of transmission blocks 404 will drive away from each other on the outside of the bidirectional screw rod 403, and the connecting rod 405 rotates and drives The detection plate 406 and the switching power supply circuit board on its top are put into the interior of the detection box 3 for fixation. At the same time, the bottom of the detection plate 406 will drive the push rod 5 to move downward, and the inclined surface at the bottom end of the push rod 5 will push the push rod 501 to move. The inclined surface at the other end of the push rod 501 will push the top rod 502 to move upward. When the top rod 502 moves upward, it will drive the anti-interference frame 503 to move upward. The anti-interference frame 503 can prevent external electromagnetic signals from causing signal interference to the switching power supply circuit board to be detected. When the detection box 3 drives the internal switching power supply circuit board to move under the action of the transmission rod 203, the surface of the switching power supply circuit board will contact with the detection box 3. The bottom of the scraper 801 contacts the switching power supply circuit board. As the switching power supply circuit board moves, the scraper 801 can scrape the surface of the switching power supply circuit board. When the switching power supply circuit board to be detected is located directly below the detection mechanism 6, the telescopic rod 602 works, and its moving end drives the detection head 603 to contact the switching power supply circuit board. At the same time, the plug 6022 at the bottom of the cover 6021 is inserted into the interior of the slot 504, which can realize the positioning of the cover 6021 and the anti-interference frame 503. Then the detected value will be sent to the comprehensive tester 7, which simulates various input and output conditions to test the power supply. The output voltage, current, power, efficiency, waveform, etc. are comprehensively tested. Finally, the detection head 603 is reset by the telescopic rod 602. When the transmission rod 203 drives the detection box 3 to reset, the transmission rack 401 moves the bidirectional screw rod 403 to rotate forward. The two sets of transmission blocks 404 will be driven closer to each other on the outside of the bidirectional screw rod 403. The connecting rod 405 rotates and drives the detection plate 406 and the switching power supply circuit board on its top to move from the inside of the detection box 3. At the same time, the anti-interference frame 503 is not reset by thrust. The worker can unload the switching power supply circuit board that has been inspected on the surface of the detection plate 406.

[0054] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method. The above specific implementation method is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
