Description

Technical Field

[0001] The utility model relates to the technical field of impregnating machines, in particular to a semi-automatic impregnating machine for preparing capacitors. Background Art

[0002] In the production process of preparing aluminum electrolytic capacitors, after the capacitors are prepared, they need to be immersed in an impregnating solution. The impregnating solution is used to fill the tiny voids and pores inside the capacitors, effectively expel air and moisture. Moreover, the impregnating solution has good heat conduction performance, which helps the capacitors maintain within a suitable operating temperature range, thereby preventing overheating from damaging the performance and lifespan of the capacitors. The impregnating solution can also enhance the stability and mechanical strength of the internal structure of the capacitors, improving the reliability and durability of the capacitors.

[0003] An impregnating machine is a device used to immerse electronic components such as capacitors in an impregnating solution to ensure that the electronic components can be fully and evenly wetted by the impregnating solution, achieving the purpose of improving the performance and quality of the components. Patent Application No. CN201410101168.1 discloses a pressure impregnating machine for preparing aluminum electrolytic capacitors, which includes a frame, an impregnating tank provided on the frame, a sealing cover that is hermetically connected to the opening of the impregnating tank to form an impregnating area, a carrier for placing the impregnated object provided on the impregnating tank, a vacuum pumping pipe, a gas discharge pipe, and a compressed air pipe connected to the impregnating area. An inner tank is provided in the impregnating tank, and there is a gap between the periphery of the inner tank and the inner wall of the impregnating tank. The pressure impregnating machine further includes a lifting mechanism located at the gap for adjusting the height of the carrier. Although this pressure impregnating machine can realize the rising or falling of the carrier with the impregnated object in the impregnating tank without opening the sealing cover, and can effectively drain the impregnating solution on the surface of the impregnated object when taking out the carrier with the impregnated object, minimizing the loss of the impregnating solution and achieving the purpose of cost savings. However, during the immersion process of the electronic components, this impregnating machine will cause the liquid level to rise and the impregnating solution to splash out, resulting in waste of the impregnating solution. When taking out the carrier after impregnation, the impregnating solution will fall, and it is necessary to continuously and repeatedly add the impregnating solution to the impregnating tank according to the liquid level gauge, increasing the liquid addition operation. Moreover, in the lifting mechanism, a motor is used to drive a single lead screw to rotate, driving the nut fixing seat to move up and down, and then driving the top support rod and the lifting plate to move up and down to push the carrier to lift and lower. This lifting structure is relatively unstable during the lifting and lowering process of the carrier. Therefore, the utility model discloses a semi-automatic impregnating machine for preparing capacitors to solve the above problems. Summary of the Utility Model

After the operation is completed, the inside of the impregnation tank 2 is exhausted to restore the pressure, and the servo motor is used to control the pressure in the impregnation tank 2. 14 drives the lifting plate 11 to move upward, so that the material rack drives the capacitor out of the impregnation liquid, and finally opens the sealing cover 3, takes out the material rack, and completes the capacitor impregnation operation. The servo motor 14 drives the lifting plate 11 to slide up and down along the guide structure 10, and uses two lifting rods 12 to drive the L-shaped bracket 9 to move up and down, thereby driving the material rack to move up and down, which can smoothly lift and lower the material rack to ensure the stability of capacitor immersion and leaching. At the same time, the enclosure 5 is set lower than the impregnation tank 2, and the splashed and overflowed impregnation liquid is discharged and collected through the drain pipe 8 of the sinking tank 7, avoiding the waste of impregnation liquid, saving costs, reducing the frequency of adding impregnation liquid, and reducing the liquid adding operation, which can greatly improve the product impregnation efficiency.
