[0008] Currently, most existing voltage testing fixtures only have one test board and one fixture board, which can test one or more power supply products at the same time. However, after a test process is completed, workers need to remove the tested power supply products and place new power supply products. During this process, the voltage testing fixture is in a downtime state, which affects the testing efficiency. Therefore, most existing voltage testing fixtures have the problem of low testing efficiency.

[0009] Therefore, there is an urgent need for a power supply testing fixture for power supply products to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a power supply testing fixture for power products, including an annular turntable 1. A connecting plate 101 is fixedly connected to the fixed end of the annular turntable 1. A PLC circuit control cabinet 102 is fixedly connected to the end of the connecting plate 101 away from the annular turntable 1. A cross-shaped support frame is fixedly connected to the inner wall of the fixed end of the annular turntable 1. A drive mechanism for driving the annular turntable 1 to rotate is fixedly connected to the top surface of the cross-shaped support frame. Two pressing mechanisms 5 for pressing power products are fixedly connected to the drive mechanism. Four testing mechanisms 2 for testing power products are fixedly connected to the top surface of the annular turntable 1. Two protective components are provided on the side of the four testing mechanisms 2 that are close to each other. A reset component is provided on one side of the annular turntable 1. The testing mechanism 2 includes a test plate 201. A placement groove 202 is opened on the top surface of the test plate 201. A test contact 203 is fixedly connected to the inner bottom surface of the placement groove 202. An indicator light 204 is provided on the side of the test plate 201 away from the support rod 3. A support plate 205 is fixedly connected to the side of each of the four test plates 201 that is close to the support rod 3.

[0028] The drive mechanism includes a support rod 3, a servo motor 301 fixedly connected to the bottom of the support rod 3, a bevel gear 302 fixedly connected to the output end of the servo motor 301, a bevel gear 103 meshing with the bevel gear 302, and the bevel gear 103 fixedly connected to the top surface of the annular turntable 1. A mounting bracket 303 is fixedly connected to the top of the support rod 3, and driving components are provided at both ends of the mounting bracket 303. Stabilizing components are provided between the two ends of the mounting bracket 303 and the pressing mechanism 5. The operator starts the servo motor 301 through the PLC circuit control cabinet 102. The servo motor 301 drives the movable end of the annular turntable 1 to rotate through the bevel gear 302 and the bevel gear 103. The servo motor 301 is the power source, and the bevel gear 302 and the bevel gear 103 transmit power.

[0029] The bottom of the pressing mechanism 5 is fixedly connected to three pressure plates 502. The bottom of each of the three pressure plates 502 is fixedly connected to multiple pressure pins 503 for pressing the power supply product. The three pressure plates 502 are respectively adapted to three placement slots 202. The pressing mechanism 5 is driven by the electric telescopic rod 305 to make the pressure pins 503 press the power supply product, so that the positive and negative terminals of the power supply product contact the test contacts 203.

[0030] The driving component includes electric telescopic rods 305 fixedly connected to both ends of the mounting bracket 303. The output ends of the two electric telescopic rods 305 are fixedly connected to the top surface of the mounting plate 501. The electric telescopic rods 305 can drive the mounting plate 501 to rise and fall, thereby realizing the overall lifting and lowering of the pressing mechanism 5.

[0031] The stabilizing component includes four limiting sleeves 304 fixedly connected to both ends of the mounting bracket 303. Each limiting sleeve 304 has a limiting rod 504 inserted inside it. The four limiting rods 504 are fixedly connected to the top surfaces of the two pressing mechanisms 5 respectively. The limiting sleeves 304 and the limiting rods 504 work together to ensure the stability of the pressing mechanism 5 during the lifting process, while avoiding damage to the electric telescopic rod 305.

[0032] The protective components include protective plates 6 placed above four support plates 205. Two protective plates 6 are located on the side of the four test mechanisms 2 closest to the support rods 3. Semicircular grooves are opened on the adjacent sides of the two protective plates 6. The two semicircular grooves are aligned. The protective plates 6 cover the space at the top of the servo motor 301 to prevent impurities from entering the bevel gear 302 and the bevel gear ring 103, which would affect the accuracy and service life of the drive mechanism.

[0033] The reset assembly includes a permanent magnet 4 fixedly connected to the outer wall of the movable end of the annular turntable 1. The permanent magnet 4 is equipped with a magnetic sensor 401, which is fixedly connected to the top surface of the connecting plate 101. When the magnetic sensor 401 detects the permanent magnet 4, it transmits an electrical signal to 102, and 102 controls the servo motor to stop, so as to reset and align 500 with each of 200.

[0034] Working principle:

[0035] First, the staff starts the servo motor 301 through the PLC circuit control cabinet 102. The servo motor 301 drives the movable end of the annular turntable 1 to rotate through the bevel gear 302 and the bevel gear ring 103. When the PLC circuit control cabinet 102 detects the magnetic force of the permanent magnet 4 through the magnetic sensor 401, it controls the servo motor 301 to stop quickly. At this time, the two pressing mechanisms 5 are located above the two test mechanisms 2 respectively. Two staff members place the power supply product in the placement slots 202 of the two test mechanisms 2 that are not blocked by the pressing mechanism 5. Then, the PLC circuit control cabinet 102 starts the electric telescopic rod 305 to drive the two pressing mechanisms 5 to descend, so that the pressure needle 503 squeezes the power supply product, so that the positive and negative terminals of the power supply product contact the test contact 203. The power supply product is then tested through the test contact 203.

[0036] The second step involves the following steps: After the power supply products have been tested, the indicator light 204 of the power supply products that passed the test will light up green, while the indicator light of those that failed will light up red. At the same time, the electric telescopic rod 305 will drive the pressing mechanism 5 to rise, and the PLC circuit control cabinet 102 will automatically control the servo motor 301 to start and drive the movable end of the annular turntable 1 to rotate 90 degrees, so that the tested power supply products and the testing mechanism 2 are moved in front of two workers. The workers will then take out the power supply products according to the red and green lights of the indicator lights 204 and store them separately. At the same time, they will replace them with new, untested power supply products for testing. During the replacement process, the PLC circuit control cabinet 102 will automatically control the support plate 205 to start and test the already placed power supply products, achieving uninterrupted testing and improving testing efficiency.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
