Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically to a leak-proof sealing device for aluminum electrolytic capacitors. Background Technology

[0002] An electrolytic capacitor is a type of capacitor. The metal foil (aluminum or tantalum) is the positive electrode, and the oxide film (aluminum oxide or tantalum pentoxide) in close contact with the metal is the dielectric. The cathode is composed of conductive materials, an electrolyte (which can be liquid or solid), and other materials. Because the electrolyte is the main component of the cathode, it is named an electrolytic capacitor. During assembly, the electrolytic capacitor is connected to the aluminum shell only by the compression of a sealing cover to prevent leakage of the electrolyte inside. However, aluminum electrolytic capacitors have low compressive strength, making them easily damaged when subjected to compression, leading to leakage. To reduce leakage, a leak-proof sealing device for aluminum electrolytic capacitors is proposed.

[0003] As disclosed in the patent announcement CN223038793U, a high-sealing, leak-proof aluminum electrolytic capacitor structure includes a heat-shrink tubing. The heat-shrink tubing contains an aluminum shell, and inside the aluminum shell are arranged, from the inside out, an anode foil, electrolytic paper, a cathode foil, and adhesive tape. The aluminum shell is filled with electrolyte. A sealing cover is provided at the top of the aluminum shell, and a rubber stopper is provided inside the sealing cover. Two lead foil strips are inserted into the rubber stopper, with the bottom ends of both lead foil strips penetrating the rubber stopper and inserting into the interior of the aluminum shell. A connecting assembly is provided outside the heat-shrink tubing, and a leak-proof sealing assembly is provided outside the sealing cover.

[0004] Although it achieves the effect of allowing the sealing expansion adhesive to flow into the interior of the annular fluid groove for filling and expansion, thus forming a second sealing effect between the sealing cover plate and the aluminum shell sleeve, forming a high sealing effect between the aluminum shell sleeve and the sealing cover plate, and positioning and pressing the sealing cover plate to prevent the sealing cover plate from being pushed upward during the process of pouring the sealing adhesive.

[0005] However, the existing sealing device does not solve the problem that it is not convenient to sequentially input the capacitor housing and capacitor back cover during use, which is not conducive to the automatic sealing process of the capacitor and affects the sealing effect and the convenience of output. Utility Model Content

[0006] The purpose of this utility model is to provide a leak-proof sealing device for aluminum electrolytic capacitors, so as to solve the problem mentioned in the background art that the sealing device is not convenient to sequentially input the capacitor shell and the capacitor back cover, which is not conducive to the automatic sealing process of the capacitor, and affects the sealing effect and output convenience of the capacitor.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A leak-proof sealing device for aluminum electrolytic capacitors includes a support platform and a placement rack. The placement rack is located at the bottom of the support platform, and a servo motor is located at the bottom of the placement rack. A drive shaft is mounted on the output end of the servo motor, and a transmission gear is fitted onto the surface of the drive shaft. A connecting shaft is movably mounted inside the support platform on one side of the drive shaft. A driven gear is fitted onto the surface of the connecting shaft on the side of the transmission gear, and the transmission gear and the driven gear mesh with each other. A first cylinder is movably mounted on the top of the placement rack, and a first push arm is mounted on the output end of the first cylinder. A linkage arm is located at the end of the first push arm away from the first cylinder, and a hinge shaft is located at the end of the linkage arm near the first push arm. The linkage arm is movably connected to the first push arm through the hinge shaft. A movable rod is fixedly mounted at the end of the linkage arm away from the first push arm, and the movable rod extends to the outside of the support platform and is movably connected to the support platform.

[0009] Optionally, a material-pulling rod is fixedly installed at the top of the movable rod, and a rotating disk is installed at the top of the connecting shaft.

[0010] Optionally, the surface of the rotating disk is provided with multiple sets of equally spaced placement holes, and a controller is provided at the top of the support platform on one side of the movable rod.

[0011] Optionally, a discharge ramp is provided at the top of the support platform, and a support frame is provided at the top of the support platform on one side of the discharge ramp.

[0012] Optionally, a feeding platform is provided at the top of the support platform on one side of the support frame, and a material bucket is provided at the top of the feeding platform.

[0013] Optionally, a second cylinder is provided at the bottom end of the support platform on one side of the movable rod, and a second push arm is installed at the output end of the second cylinder.

[0014] Optionally, a third cylinder is installed at the top of the support frame, and a third push arm is installed at the output end of the third cylinder.

[0015] Optionally, a pressing block is installed at the bottom end of the third push arm, and the pressing block is fixedly connected to the third push arm.

[0016] Optionally, a fourth cylinder is provided on the side wall of the feeding platform, and a fourth push arm is installed at the output end of the fourth cylinder.

[0017] Optionally, a scraper plate is provided at the end of the fourth push arm away from the fourth cylinder, and the scraper plate is slidably connected to the feeding table.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the sealing device not only realizes the sequential input of capacitor housing and capacitor back cover, which facilitates the automatic sealing process of capacitor, but also improves the sealing effect of capacitor and the convenience of output.

[0019] The capacitor back covers are stacked sequentially in the material bin. The capacitor to be sealed is placed in the placement hole, which is tapered to prevent the capacitor from falling out. A servo motor drives the drive shaft to rotate, which in turn drives the driven gear through the transmission gear. The driven gear drives the connecting shaft and the rotating disk to rotate, which in turn drives the capacitor to rotate below the feeding platform. A fourth cylinder drives the fourth push arm to move, which in turn drives the scraper plate to slide on the surface of the feeding platform. The scraper plate moves the capacitor back cover at the bottom of the material bin and drops it through the hole on the surface of the feeding platform onto the capacitor. The rotating disk continues to rotate and moves it to below the lower pressing block. A third cylinder drives the third push arm to move downward, which in turn drives the lower pressing block to move downward. Upon contact with the capacitor, the lower pressing block presses the capacitor back cover into the capacitor to complete the seal. This process of sequentially inputting capacitor housings and capacitor back covers facilitates automatic sealing of capacitors and improves the sealing effect.

[0020] After sealing, the capacitor rotates with the rotating disk to the top of the second push arm. The second cylinder drives the second push arm to move upward, which in turn moves the capacitor upward and removes it from the placement hole. The first cylinder drives the first push arm to move, which in turn drives the linkage arm to rotate via the hinge shaft. The linkage arm drives the movable rod to rotate, which in turn drives the feeding rod to rotate. This causes the feeding rod to contact the capacitor and push the capacitor onto the surface of the discharge ramp, allowing it to slide off and be discharged. This completes the output of the capacitor and improves the convenience of capacitor output. Attached Figure Description

[0036] like Figures 1 to 6As shown, an embodiment of this utility model provides a leak-proof sealing device for aluminum electrolytic capacitors, including a support platform 1 and a placement rack 13. The placement rack 13 is provided at the bottom of the support platform 1, and a servo motor 10 is provided at the bottom of the placement rack 13. The servo motor 10 provides power drive. A drive shaft 11 is installed at the output end of the servo motor 10. A transmission gear 12 is fitted on the surface of the drive shaft 11. A connecting shaft 19 is movably installed inside the support platform 1 on one side of the drive shaft 11. A driven gear 18 is fitted on the surface of the connecting shaft 19 on one side of the transmission gear 12, and the transmission gear 12 and the driven gear 18 mesh with each other. A first cylinder 14 is movably installed at the top of the placement rack 13. The first cylinder 14 provides power drive. Driven by force, a first push arm 15 is installed at the output end of the first cylinder 14. A linkage arm 17 is provided at the end of the first push arm 15 away from the first cylinder 14. A hinge shaft 16 is provided at the end of the linkage arm 17 near the first push arm 15, and the linkage arm 17 is movably connected to the first push arm 15 through the hinge shaft 16. A movable rod 9 is fixedly installed at the end of the linkage arm 17 away from the first push arm 15, and the movable rod 9 extends to the outside of the support platform 1 and is movably connected to the support platform 1. A feeding rod 8 is fixedly installed at the top of the movable rod 9. A rotating disk 2 is installed at the top of the connecting shaft 19. The surface of the rotating disk 2 is provided with multiple sets of equally spaced placement holes 3. A controller 28 is provided at the top of the support platform 1 on one side of the movable rod 9.

[0037] In this utility model, the controller 28 is a Siemens S7-200. Since this controller 28 is existing technology, its internal structure, working principle, and connection and control methods with the electrical components described in this application will not be elaborated further. The capacitor's back cover is sequentially placed in the material bin 5. The capacitor to be sealed is placed in the placement hole 3, which is tapered to prevent the capacitor from falling out. The servo motor 10 is turned on, driving the drive shaft 11 to rotate. Through the meshing of the transmission gear 12 and the driven gear 18, the drive shaft 11 drives the driven gear 18 to rotate. The driven gear 18 then drives the connecting shaft 19 and the rotating disk 2 to rotate, which in turn drives the capacitor to rotate. Below the feeding platform 4, the fourth cylinder 26 is activated, which drives the fourth push arm 27 to move. The fourth push arm 27 drives the scraper plate 20 to slide on the surface of the feeding platform 4. The scraper plate 20 drives the capacitor back cover at the bottom of the material barrel 5 to move and fall onto the capacitor through the hole on the surface of the feeding platform 4. The rotating disk 2 drives it to continue rotating and move it to below the lower pressing block 25. The third cylinder 23 is activated, which drives the third push arm 24 to move downward. The third push arm 24 drives the lower pressing block 25 to move downward. After contacting the capacitor, the capacitor back cover is pressed into the capacitor to complete the seal. This realizes the sequential input of the capacitor shell and capacitor back cover, which facilitates the automatic sealing process of the capacitor and improves the sealing effect of the capacitor.

[0038] The top of the support platform 1 is provided with a discharge ramp 7, and a support frame 6 is provided on the top of the support platform 1 on one side of the discharge ramp 7.

[0039] A feeding platform 4 is provided at the top of the support platform 1 on one side of the support frame 6. A material bucket 5 is provided at the top of the feeding platform 4. A second cylinder 21 is provided at the bottom of the support platform 1 on one side of the movable rod 9. The second cylinder 21 plays a power driving role. A second push arm 22 is installed at the output end of the second cylinder 21.

[0040] A third cylinder 23 is installed at the top of the support frame 6. The third cylinder 23 serves as a power drive, and a third push arm 24 is installed at the output end of the third cylinder 23.

[0041] The bottom end of the third push arm 24 is equipped with a pressing block 25, and the pressing block 25 is fixedly connected to the third push arm 24. A fourth cylinder 26 is provided on the side wall of the feeding table 4. The fourth cylinder 26 plays the role of power drive, and the output end of the fourth cylinder 26 is equipped with a fourth push arm 27.

[0042] The end of the fourth push arm 27 away from the fourth cylinder 26 is provided with a scraper plate 20, and the scraper plate 20 is slidably connected to the feeding table 4.

[0043] After sealing, the capacitor rotates with the rotating disk 2 to the top of the second push arm 22. The second cylinder 21 is opened, and the second cylinder 21 drives the second push arm 22 to move upward. The second push arm 22 drives the capacitor upward and removes it from the placement hole 3. Then, the first cylinder 14 is opened, and the first cylinder 14 drives the first push arm 15 to move. The first push arm 15 drives the linkage arm 17 to rotate through the hinge shaft 16. The linkage arm 17 drives the movable rod 9 to rotate. The movable rod 9 drives the feeding rod 8 to rotate, so that the feeding rod 8 contacts the capacitor and pushes the capacitor to the surface of the discharge ramp 7, allowing the capacitor to slide off the surface of the discharge ramp 7 and be discharged, thus completing the output of the capacitor and improving the convenience of capacitor output.

[0044] The working principle of the technical solution provided by this utility model is as follows: The back covers of the capacitors are stacked in the material barrel 5, and the capacitors to be sealed are placed in the placement hole 3. The placement hole 3 is tapered, so the capacitors will not fall out of the placement hole 3 after being placed in it. The servo motor 10 drives the drive shaft 11 to rotate. The drive shaft 11 drives the driven gear 18 to rotate through the transmission gear 12. The driven gear 18 drives the connecting shaft 19 and the rotating disk 2 to rotate. The rotating disk 2 drives the capacitor to rotate to the bottom of the feeding platform 4. The fourth cylinder 26 drives the fourth push arm 27 to move. The fourth push arm 27 drives the scraper plate 20 to slide on the surface of the feeding platform 4. The scraper plate 20 drives the bottom capacitor back cover in the material barrel 5 to move and fall from the hole on the surface of the feeding platform 4 onto the capacitor. The rotating disk 2 drives it to continue rotating and move it to the bottom of the pressing block 25. The third cylinder 26 drives the capacitor back cover to move to the bottom of the feeding platform 4. Cylinder 23 drives the third push arm 24 to move downwards, which in turn drives the lower pressure block 25 to move downwards. After contacting the capacitor, the lower pressure block 25 presses the capacitor back cover into the capacitor to complete the seal. The sealed capacitor then rotates with the rotating disk 2 to the top of the second push arm 22. The second cylinder 21 drives the second push arm 22 to move upwards, which in turn drives the capacitor upwards and removes it from the placement hole 3. The first cylinder 14 drives the first push arm 15 to move, which in turn drives the linkage arm 17 to rotate via the hinge shaft 16. The linkage arm 17 drives the movable rod 9 to rotate, which in turn drives the feeding rod 8 to rotate, so that the feeding rod 8 contacts the capacitor and pushes the capacitor onto the surface of the discharge ramp 7, allowing the capacitor to slide off the surface of the discharge ramp 7 and be discharged, thus completing the output of the capacitor. The above is the complete usage of the aluminum electrolytic capacitor anti-leakage sealing device.
