Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum electrolytic capacitor sealing technology, specifically to an aluminum electrolytic capacitor sealing device. Background Technology
[0002] An aluminum electrolytic capacitor is a type of capacitor that uses aluminum as the main electrode material. Through an electrolytic process, an oxide film forms on the aluminum surface as the dielectric. When a positive voltage is applied across the capacitor, aluminum atoms on the anode foil lose electrons to become aluminum ions, which combine with oxygen ions in the electrolyte to form a thin aluminum oxide film. Simultaneously, a reduction reaction occurs on the cathode foil, attracting cations from the electrolyte to accumulate on its surface. This creates an electric field between the anode and cathode foils, storing charge and thus achieving charging.
[0003] A Chinese patent with publication number CN220895353U discloses a sealing device for aluminum electrolytic capacitors. The key technical features include a worktable, a switching mechanism, a sealing mechanism, and a waist-binding and unloading mechanism. The worktable has four corner supports on its bottom surface. The switching mechanism is located at the center of the upper surface of the worktable. The sealing mechanism includes a lead screw, a fixed cylinder, a support frame, and a sealing post. The fixed cylinder is fixedly connected to the upper surface of the worktable, and the lead screw is rotatably connected to the center of the fixed cylinder. The outer surface of the fixed cylinder has an clearance opening. The support frame is threadedly connected to the lead screw via a connecting block. The sealing head has a trapezoidal groove inside. The waist-binding and unloading mechanism is located on the left front end of the upper surface of the worktable. This sealing device for aluminum electrolytic capacitors ensures uninterrupted sealing of the capacitors, has a more compact structure, occupies less space, and allows for direct waist-binding after sealing, ensuring continuous operation and improving work efficiency.
[0004] When sealing aluminum electrolytic capacitors, existing sealing devices use a feeding trough for feeding. However, the feeding trough is an inclined U-shaped plate. Therefore, the structure of the U-shaped trough may cause uneven friction and gravity forces on the capacitors during the sliding process, resulting in unstable feeding speed. Sometimes the capacitors will clump together and slide down quickly, and sometimes they will slide down slowly individually. This will bring difficulties to the subsequent sealing operation and make it difficult to achieve a stable automated production process. To address this, we propose an aluminum electrolytic capacitor sealing device. Utility Model Content

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.
[0031] Please see Figure 1-2 This utility model provides a technical solution: a sealing device for aluminum electrolytic capacitors, including a workbench 1 and a capacitor body 9. A microcontroller 2, a material tray 3, a material binding device 4, a sealing device 5, and a material discharge chute 6 are mounted on the surface of the workbench 1. A feeding structure 7 is also provided on the surface of the workbench 1. By setting the feeding structure 7, the stability and smoothness of the feeding process of the capacitor body 9 are ensured, avoiding the problem of unstable material discharge speed caused by the feeding method in the prior art. This provides a reliable foundation for subsequent automated sealing operations, improving production efficiency and product quality.

It also prevents operators from accidentally touching moving parts and causing safety accidents.
[0032] Reference Figure 2 and Figure 3 and Figure 4 As shown in this embodiment: the feeding structure 7 includes a support plate 701, which is fixedly connected to the surface of the workbench 1. A feeding cylinder 702 is fixedly connected to the side of the support plate 701 away from the workbench 1. A U-shaped plate 703 is fixedly connected to the arc surface of the feeding cylinder 702. A telescopic rod 704 is fixedly connected to the inner wall of the U-shaped plate 703. A push plate 705 is fixedly connected to the output end of the telescopic rod 704. An arc-shaped hole 706 is opened on the arc surface of the feeding cylinder 702. The capacitor body 9 is located inside the feeding cylinder 702. A groove 707 is opened on the bottom surface of the inner wall of the feeding cylinder 702. Several rollers 708 are rotatably connected to the inner wall of the groove 707. The rollers 708 rotate with the capacitor body 9 when it moves. The rotation of the rollers 708 greatly reduces the friction between the capacitor body 9 and the bottom surface of the feeding cylinder 702, so that the capacitor body 9 can move more smoothly. Two baffles 709 are fixedly connected to the arc surface of the feeding cylinder 702. The two baffles 709 are located on both sides of the arc-shaped hole 706, respectively. The two baffles 709 are located on both sides of the arc-shaped hole 706, which can prevent the capacitor body 9 from accidentally falling off the sides of the arc-shaped hole 706 during the movement, and ensure the stability of the movement path of the capacitor body 9. A protective pad 710 made of rubber is fixedly connected to the side of the push plate 705 near the feeding cylinder 702. When the push plate 705 pushes the capacitor body 9, it can prevent the push plate 705 from making direct hard contact with the capacitor body 9, and prevent scratches, wear and other damage to the surface of the capacitor body 9, thus protecting the capacitor body 9.
[0033] Reference Figure 5 and Figure 6 As shown, specifically, the protective structure 8 includes a bracket 81, which is fixedly connected to the surface of the workbench 1. A rotating shaft 82 rotatably passes through the surface of the bracket 81. A drive arm 83 is fixedly connected to the arc surface of the rotating shaft 82. A protective cover 84 is fixedly connected to one end of the drive arm 83. The size of the protective cover 84 is larger than that of the microcontroller 2. A torsion spring 85 is fitted onto the arc surface of the rotating shaft 82. The two ends of the torsion spring 85 are fixedly connected to the bracket 81 and the rotating shaft 82, respectively. A pin 86 is slidably inserted into the surface of the bracket 81. Two circular grooves 87 are formed on the surface of the drive arm 83. The size of the pin 86 is adapted to the size of the circular grooves 87. A spring 88 is fitted onto the arc surface of the pin 86. The two ends of the spring 88 are fixedly connected to the pin 86 and the bracket 81, respectively. Under the action of the spring 88, the pin 86 is tightly inserted into the circular groove 87, thereby preventing the pin 86 from falling out of the circular groove 87 due to shaking. One end of the rotating shaft 82 is fixedly connected to a turntable 89. The vertical cross section of the turntable 89 is in the shape of a cross. The turntable 89 drives the rotating shaft 82 to rotate, and the turntable 89 facilitates the rotation of the turntable 89.
[0034] Working Principle: When using this aluminum electrolytic capacitor sealing device, firstly, multiple capacitor bodies 9 are placed into the feeding cylinder 702. At this time, the telescopic rod 704 is activated. The output end of the telescopic rod 704 will drive the push plate 705 to move towards the feeding cylinder 702. Since the capacitor bodies 9 are located inside the feeding cylinder 702, the push plate 705 will push the capacitor bodies 9 during the movement. The roller 708 will rotate along with the capacitor bodies 9 as they move. The rotation of the roller 708 greatly reduces the friction between the capacitor bodies 9 and the bottom surface of the feeding cylinder 702, allowing the capacitor bodies 9 to move more smoothly. At the same time, the arc-shaped opening on the arc surface of the feeding cylinder 702... The hole 706 is used to allow the capacitor body 9 to be moved from the feed cylinder 702 to the designated position under the push of the push plate 705. The two baffles 709 are located on both sides of the arc-shaped hole 706, which can prevent the capacitor body 9 from accidentally falling from both sides of the arc-shaped hole 706 during the movement, and ensure the stability of the movement path of the capacitor body 9. The rubber protective pad 710 is fixedly connected to the side of the push plate 705 near the feed cylinder 702. When the push plate 705 pushes the capacitor body 9, it can prevent the push plate 705 from making direct hard contact with the capacitor body 9, and prevent scratches, wear and other damage to the surface of the capacitor body 9, thus protecting the capacitor body 9.
[0035] If the microcontroller 2 needs to be operated during the operation of the device, first rotate the turntable 89. The turntable 89 drives the rotating shaft 82 to rotate, the rotating shaft 82 drives the drive arm 83 to rotate, and the drive arm 83 drives the protective cover 84 to rotate around the rotating shaft 82. At this time, the torsion spring 85 undergoes elastic deformation. When the protective cover 84 rotates to a suitable angle, insert the pin 86 into the circular groove 87 on the surface of the drive arm 83. Under the action of the spring 88, the pin 86 is tightly inserted into the circular groove 87, thereby fixing the position of the protective cover 84 and exposing the inside of the device for the operator to perform relevant operations. After the operation is completed, pull out the pin 86. Under the elastic force of the torsion spring 85, the protective cover 84 will automatically rotate back to its original position, protecting the microcontroller 2 and other components on the surface of the workbench 1, preventing dust, debris and other objects from entering the device and affecting the normal operation of the equipment. At the same time, it can also prevent the operator from accidentally touching the moving parts and causing a safety accident.
