Abstract

Technical Field
[0001] This utility model relates to the field of immersion device technology, and in particular to an immersion device for the production of aluminum electrolytic capacitors. Background Technology
[0002] Aluminum electrolytic capacitors are widely used electronic components due to their large capacity, low cost, and wide operating voltage range. They are made by inserting a bent aluminum strip as the positive electrode into an aluminum cylinder containing liquid electrolyte as the negative electrode. The capacitors require DC voltage treatment to form an oxide film on the positive electrode as the dielectric. They are also used for signal coupling when high precision is not required. Aluminum electrolytic capacitors have positive and negative electrodes and must not be connected in reverse. Impregnation is a crucial production process in aluminum electrolytic capacitor manufacturing; the quality of the impregnation of the capacitor core directly affects the overall quality of the capacitor.
[0003] Most soaking devices on the market today rotate on their own to allow multiple capacitors to be soaked more thoroughly and quickly to meet user needs. However, some problems still exist. For example, the lack of protective components inside the soaking device can cause the multiple capacitors to collide with each other during rotation, resulting in damage. Utility Model Content
[0004] To address the technical problem of multiple capacitors colliding and being damaged during rotation within the immersion device, this utility model provides an immersion device for the production of aluminum electrolytic capacitors.
[0005] This utility model is achieved using the following technical solution: an immersion device for producing aluminum electrolytic capacitors, comprising a workbench, an immersion tank, and a cleaning tank. The cleaning tank and the immersion tank are both installed on the top of the workbench. A support column is fixedly connected to the top of the workbench, and a top plate is fixedly connected above the support column. A movable plate that can move laterally is provided on the top plate. A hydraulic rod is rotatably connected to the bottom end of the movable plate. A first servo motor coaxial with the fixed end of the hydraulic rod is fixedly connected to the top of the movable plate. A storage box for placing capacitors is fixedly connected to the bottom end of the output end of the hydraulic rod. An adjustment component is provided inside the storage box. Multiple drying fans are installed on the upper part of the cleaning tank.
[0006] Through the above technical solution, the hydraulic rod fixed to the bottom of the moving plate can drive the storage box to move up and down, and the activation of the second servo motor can drive the storage box to move horizontally left and right, so that multiple capacitors inside the storage box can be located inside the soaking tank and the cleaning tank. The activation of the first servo motor can drive the storage box to rotate inside the soaking tank and the cleaning tank, so that the capacitors can be better soaked and cleaned.
[0007] As a further improvement to the above solution, an opening is provided on the top plate, and a reciprocating lead screw is rotatably connected inside the opening. A second servo motor, coaxial with the reciprocating lead screw, is fixedly connected to the vertical parallel outer side of the top plate. An auxiliary rod is also fixedly connected inside the opening. The moving plate is threaded onto the outer side of the reciprocating lead screw, and the moving plate slides on the outer side of the auxiliary rod.
[0008] Through the above technical solution, the second servo motor drives the reciprocating lead screw to rotate, so that the moving plate with the thread sleeve on the outside of the reciprocating lead screw moves horizontally in the opening of the top plate, and at the same time slides on the outside of the auxiliary rod.
[0009] As a further improvement to the above solution, the adjustment component includes a mounting groove formed on the inner side of the storage box, and a first adjustment plate and a second adjustment plate are slidably installed inside the mounting groove.
[0010] As a further improvement to the above solution, both the first adjusting plate and the second adjusting plate are made of rubber. The upper end of the first adjusting plate is provided with a plurality of first adjusting grooves, and the lower end of the second adjusting plate is provided with a second adjusting groove that engages with the first adjusting grooves.
[0011] Through the above technical solution, the multiple mounting slots opened on the inner side of the storage box and the first and second adjustment slots opened on the first and second adjustment plates can make the first and second adjustment plates flexibly adjustable to accommodate capacitors of different sizes.
[0012] As a further improvement to the above solution, the storage box is provided with through holes on all four sides and at the bottom.
[0013] As a further improvement to the above solution, both the cleaning tank and the soaking tank are equipped with output pipes and input pipes.
[0014] The above technical solution involves installing output and input pipes on the cleaning tank and soaking tank, which facilitates the replacement of deionized water inside the cleaning tank and electrolyte solution inside the soaking tank.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting the first and second adjustment plates in the adjustment assembly, this utility model can separate the internal space of the storage box, which can prevent the capacitors inside the storage box from colliding with each other and causing damage. In addition, the first and second adjustment slots opened on the first and second adjustment plates, as well as the mounting slots opened on the inner side of the storage box, can be used for capacitors of different sizes, improving the practicality of the equipment.
[0016] 2. This utility model uses a hydraulic rod to move the storage box up and down, and a second servo motor to move the storage box horizontally left and right, so that multiple capacitors inside the storage box can be located inside the soaking tank and the cleaning tank. This allows the electrolyte to be removed from the soaked capacitors inside the cleaning tank, preventing corrosion of the capacitor shells. In addition, the drying fan installed on the cleaning tank can remove moisture from the surface of the cleaned capacitors, improving the overall production efficiency of capacitors.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0020] Please combine Figures 1-3This embodiment of an immersion apparatus for producing aluminum electrolytic capacitors includes a workbench 1, an immersion tank 2, and a cleaning tank 3. Both the cleaning tank 3 and the immersion tank 2 are mounted on the top of the workbench 1. A support column 4 is fixedly connected to the top of the workbench 1, and a top plate 5 is fixedly connected above the support column 4. A laterally movable plate 6 is provided on the top plate 5. A hydraulic rod 7 is rotatably connected to the bottom end of the movable plate 6. A first servo motor 8, coaxial with the fixed end of the hydraulic rod 7, is fixedly connected to the top of the movable plate 6. A device for placing capacitors is fixedly connected to the bottom end of the output end of the hydraulic rod 7. Storage box 9 has an adjustment component inside. Multiple drying fans 10 are installed on the upper part of the washing box 3. An opening 11 is opened on the top plate 5. A reciprocating screw 12 is rotatably connected inside the opening 11. A second servo motor 13, coaxial with the reciprocating screw 12, is fixedly connected to the outer side of the top plate 5 vertically and parallel. An auxiliary rod 14 is also fixedly connected inside the opening 11. A moving plate 6 is threaded onto the outer side of the reciprocating screw 12 and slides on the outer side of the auxiliary rod 14. Through holes 20 are opened on all four sides and the bottom of the storage box 9.
[0021] The second servo motor 13, which is vertically and parallel to the outer side of the top plate 5, drives the reciprocating screw 12 located inside the opening 11 to rotate, so that the moving plate 6, which is threaded on the outer side of the reciprocating screw 12, can move horizontally within the opening 11 of the top plate 5, and also slide on the outer side of the auxiliary rod 14; thus realizing the horizontal movement of the storage box 9. The activation of the first servo motor 8 can drive the hydraulic rod 7 to rotate on the bottom of the moving plate 6, so that the storage box 9 fixed to the bottom of the hydraulic rod 7 can rotate synchronously in the soaking box 2 or the cleaning box 3, so that the electrolyte solution inside the soaking box 2 and the deionized water inside the cleaning box 3 can enter through the through holes 20 opened on the inner side and bottom side of the storage box 9, which can fully soak or clean the capacitor. Finally, the moisture on the surface of the capacitor after cleaning is removed by the drying fan 10 installed on the cleaning tank 3.
[0022] Combination Figure 2 and Figure 3 The adjustment component includes a mounting groove 15 on the inner side of the storage box 9. A first adjustment plate 16 and a second adjustment plate 17 are slidably installed inside the mounting groove 15. Both the first adjustment plate 16 and the second adjustment plate 17 are made of rubber. The upper end of the first adjustment plate 16 is provided with a plurality of first adjustment grooves 18, and the lower end of the second adjustment plate 17 is provided with a second adjustment groove 19 that engages with the first adjustment grooves 18.
[0023] By adjusting the first adjusting plate 16 and the second adjusting plate 17 in the assembly, the internal space of the storage box 9 can be separated, which can prevent the capacitors inside the storage box 9 from colliding with each other and causing damage. In addition, the first adjusting groove 18 and the second adjusting groove 19 opened on the first adjusting plate 16 and the second adjusting plate 17, as well as the mounting groove 15 opened on the inner side of the storage box 9, can be used for capacitors of different sizes, improving the practicality of the equipment.
[0024] Combination Figure 1 Both the cleaning tank 3 and the soaking tank 2 are equipped with an output pipe 21 and an input pipe 22.
[0025] By installing output pipe 21 and input pipe 22 on the cleaning tank 3 and soaking tank 2, it is convenient to replace the deionized water inside the cleaning tank 3 and the electrolyte solution inside the soaking tank 2. The implementation principle of the immersion device for producing aluminum electrolytic capacitors in this application embodiment is as follows: Before soaking, the electrolyte solution inside the soaking tank 2 and the deionized water inside the cleaning tank 3 are replaced through the output pipe 21 and the input pipe 22. Next, based on the size of the capacitor, the second adjustment plate 17 is first installed on the first adjustment plate 16, and fine-tuned according to the setting of the first adjustment slot 18 and the second adjustment slot 19. Then, the first adjustment plate 16 and the second adjustment plate 17, which are in a cross-shaped engagement, are installed on the appropriate mounting slot 15 inside the storage box 9. Then, the capacitors are placed separately in different spaces inside the storage box 9. At this time, the second servo motor 13 is turned on to drive the reciprocating screw 12 located inside the opening 11 to rotate, so that the moving plate 6, which is threaded on the outside of the reciprocating screw 12, can move horizontally in the opening 11 of the top plate 5, and at the same time slide on the outside of the auxiliary rod 14 until the storage box 9 is directly above the soaking tank 2. Then, the hydraulic rod 7 is turned on to drive the storage box 9 to move downward until the storage box 9 is completely in the soaking tank 2 filled with electrolyte solution. Then, the first servo motor 8 is turned on to drive the hydraulic rod 7 to rotate on the bottom end of the moving plate 6, so that the storage box 9, which is fixed to the bottom end of the hydraulic rod 7, rotates in the soaking tank 2, so that the capacitor can be completely soaked. After the capacitors are soaked, the storage box 9 is moved out of the soaking box 2 and then into the cleaning box 3 by the cooperation of the hydraulic rod 7, the first servo motor 8 and the second servo motor 13. This allows the deionized water to neutralize the electrolyte solution on the surface of the capacitors. Then, the second servo motor 13 is turned on to move the storage box 9 to the drying fan 10 installed on the upper part of the cleaning box 3 for drying.
[0026] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
