Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum electrolytic capacitors, and in particular to a test fixture for aluminum electrolytic capacitors. Background Technology
[0002] Aluminum electrolytic capacitors are made by inserting a bent aluminum strip as the positive electrode into an aluminum cylinder containing liquid electrolyte as the negative electrode. They also require DC voltage treatment to form an oxide film on the positive electrode as the dielectric. Their characteristics include large capacitance, but also high leakage current, poor stability, and polarity. They are suitable for power supply filtering or low-frequency circuits. When using them, the positive and negative terminals must not be reversed.
[0003] After aluminum electrolytic capacitors are manufactured, in order to eliminate defective products, it is necessary to test the electrical stability of the aluminum electrolytic capacitors. When measuring aluminum electrolytic capacitors, the leads of the aluminum electrolytic capacitors are usually clamped one by one. The clamping time is long, and the testing time is also long, which affects the production efficiency. Utility Model Content

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. Example
[0031] Reference Figure 1-6This utility model discloses an aluminum electrolytic capacitor testing fixture, including an operating table 1, a testing table 2 at the upper end of the operating table 1, a testing groove 3 at the upper end of the testing table 2, and multiple electrolytic capacitor slots 6 on the inner bottom wall of the testing groove 3. Each of the multiple electrolytic capacitor slots 6 has two pin slots 8 on its inner bottom wall. Preferably, a patch is provided on the side wall of the pin slot 8 opposite to the clamping piece 21, and the patch is energized and electrically connected to an indicator light 20. If a problem occurs with the aluminum electrolytic capacitor, the clamping piece... 21. The leads of the aluminum electrolytic capacitor are attached to the surface mount. When the surface mount is energized, the indicator light 20 will light up if there is no problem, otherwise it will not light up. Clamping plates 21 are slidably installed on the inner bottom wall of multiple lead slots 8. Multiple indicator lights 20 are installed on the upper end of the test platform 2. Each clamping plate 21 is equipped with a clamping mechanism 9. Each clamping mechanism 9 includes a push rod 901 and a first spring 902. The push rod 901 is fixedly connected to one side of the clamping plate 21, and the first spring 902 is fixedly connected to the lead slot 8 and the clamping plate 21. Between 1 and 2, and the first spring 902 is sleeved on the circumferential side of the push rod 901; the test table 2 is provided with two sets of pushing mechanisms 11, which are respectively connected to multiple push rods 901 to realize the movement of multiple push rods 901. Each set of pushing mechanisms 11 includes a push groove 1105 and a push plate 1101. The push groove 1105 is opened in the test table 2, and the push plate 1101 is slidably connected in the push groove 1105. Multiple push rods 901 all move through one side wall of the push groove 1105, and Multiple push rods 901 are fixed to push plates 1101. The aluminum electrolytic capacitor is inserted into the electrolytic capacitor slot 6, and the two leads of the aluminum electrolytic capacitor are inserted into the two lead slots 8. Pushing the push plates 1101 on both sides pushes the push rods 901. The push rods 901 push the clamping pieces 21 closer to the leads, so that the leads can be clamped between the lead slots 8 and the clamping pieces 21. Multiple clamping pieces 21 can be moved to fix the leads of multiple aluminum electrolytic capacitors at the same time, improving the processing efficiency.
[0032] Each push mechanism 11 includes a rotating block 1102 and a motor 1103. The motor 1103 is fixedly connected to the inner top wall of the push groove 1105, and the rotating block 1102 is fixedly connected to the output end of the motor 1103. When the rotating block 1102 rotates to the longer end, the push plate 1101 pushes the push rod 901 to move, starting the motor 1103. The output end of the motor 1103 drives the rotating block 1102 to rotate. When the rotating block 1102 rotates to the longer end, the rotating block 1102 pushes the push plate 1101 to move. The push plate 1101 can push the movement of multiple push rods 901 on the same side laterally, so that the clamping plate 21 can clamp the leads of the aluminum electrolytic capacitor for convenient testing.
[0033] Two limiting rods 1104 are fixedly connected between the side walls of the pusher trough 1105. The push plate 1101 is slidably connected to the circumferential side of the two limiting rods 1104. The sliding cooperation between the limiting rods 1104 and the push plate 1101 can improve the movement stability of the push plate 1101.
[0034] Each of the multiple electrolytic capacitor slots 6 is provided with two clamping plates 7, and each clamping plate 7 is provided with two sets of limiting mechanisms 10. The two sets of limiting mechanisms 10 are respectively connected to two opposite side walls of the electrolytic capacitor slot 6. Each set of limiting mechanisms 10 includes a circular groove 1001 and a second spring 1002. The circular groove 1001 is opened on one side wall of the electrolytic capacitor slot 6, and the second spring 1002 is fixedly connected to one side wall of the circular groove 1001. The clamping plate 7 is fixed to the other side of the second spring 1002. When an aluminum electrolytic capacitor is inserted between the two clamping plates 7, the second spring 1002 can drive the clamping plate 7 to move, thereby limiting the overall position of the aluminum electrolytic capacitor.
[0035] The upper end of the operating table 1 has a circular groove 16. The inner bottom wall of the circular groove 16 is rotatably connected to a gear 17. The gear 17 is fixed to the lower end of the test table 2 through a fixed shaft. The inner bottom wall of the circular groove 16 has a rectangular groove 12.

A pull 4 is fixedly connected to the other side of the rack 13. The pull 4 moves through the lower end of the operating table 1 and is fixedly connected to a foot pedal 5. After the aluminum electrolytic capacitors in the horizontal row are installed, stepping down on the foot pedal 5 will pull the rack 13 to move. The third spring 14 will be in a stretched state. The rack 13 and the gear 17 will mesh. The rotation of the gear 17 can drive the test table 2 to rotate, so that the other row of the test table 2 can rotate to a position closer to the employee for easy installation or handling.
[0036] The inner bottom wall of the rectangular groove 12 is provided with a guide groove 18. A guide wheel 19 is installed on one side wall of the guide groove 18 through a mounting plate. The lifting 4 is connected to the circumferential side of the guide wheel 19. The guide groove 18 and the guide wheel 19 can facilitate the lifting 4 to change direction.
[0037] Two slide rods 15 are fixedly connected between the side walls of the rectangular groove 12. The rack 13 is slidably connected to the circumferential side of the two slide rods 15. The slide rods 15 and the rack 13 slide in cooperation, which can improve the movement stability of the rack 13.
[0038] The implementation principle of the above embodiment is as follows: an aluminum electrolytic capacitor is inserted into the electrolytic capacitor slot 6, and the two pins of the aluminum electrolytic capacitor are inserted into the two pin slots 8. The push plates 1101 on both sides are pushed, and the two push plates 1101 push the push rod 901. The push rod 901 pushes the clamping piece 21 closer to the pin, so that the pin can be clamped between the pin slot 8 and the clamping piece 21. Multiple clamping pieces 21 can be pushed to move, and the pins of multiple aluminum electrolytic capacitors can be fixed at the same time, thereby improving the processing efficiency.
