Description

Technical Field

[0001] This utility model relates to the field of capacitor production equipment technology, and in particular to a processing and winding machine for aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitors play a vital role in electronic circuits, performing filtering, coupling, and bypassing functions, and are widely used in communication equipment, audio-visual systems, home appliances, and instrumentation. During their manufacturing process, positive aluminum foil, negative aluminum foil, and electrolytic paper are stacked in sequence and then wound using a winding machine. Simultaneously, leads are attached to the corresponding aluminum foils. The key step in the production process of aluminum electrolytic capacitors is winding the foil roll to the terminals using a winding machine. To ensure winding accuracy and production safety, the foil roll must be securely positioned to prevent it from shaking and falling off during the winding process.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the commonly used foil roll limiting method uses multiple screws to fasten baffles, which limit and fix the foil roll. In actual production, when it is necessary to replace the foil roll, the operator must spend a lot of time unscrewing each screw one by one. The operation process is cumbersome and lengthy, resulting in extremely low unloading efficiency, which is difficult to meet the needs of the production line for rapid material change and improved production efficiency. Therefore, in order to solve the above problems, a processing and winding machine for aluminum electrolytic capacitors is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing common foil roll limiting method, which uses multiple screws to fasten baffles and limit and fix the foil roll. When replacing the foil roll, the screws need to be unscrewed one by one, which is cumbersome, inefficient, and cannot meet the needs of rapid replacement. Therefore, this invention proposes a processing and winding machine for aluminum electrolytic capacitors.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a winding machine for processing aluminum electrolytic capacitors, comprising a winding machine body, an information screen mounted on the surface of the winding machine body, a placement cylinder mounted on the surface of the winding machine body, a circular chamber slidably connected inside the placement cylinder, a baffle fixedly connected to the arc surface of the circular chamber, an adjustment device provided on the inner wall of the placement cylinder, the adjustment device including a fixing groove, the fixing groove being opened in the inner wall of the placement cylinder, two slots being opened on the inner wall of the fixing groove, a fixing block being fixedly connected to one end of the circular chamber, the fixing block being slidably connected to the inner wall of the fixing groove, and two slots being opened on the arc surface of the fixing block. Two circular grooves are connected to the inner walls of two of them, and two circular rods are fixedly connected to the ends of the two springs that are far apart from each other. The circular rods are slidably connected to the inner walls of the circular grooves, and the size of the circular rods is adapted to the size of the grooves. A threaded rod is rotatably connected inside the circular compartment. A rotating shaft is fixedly connected to one end of the threaded rod. Two arc-shaped holes are opened at the end of the fixed block near the rotating shaft. A connecting rod is slidably connected to the inner wall of the arc-shaped holes. The connecting rod is fixedly connected to the arc surface of the circular rod. A circular ring block is threadedly connected to the arc surface of the threaded rod. Two connecting plates are fixedly connected to the arc surface of the circular ring block. The connecting plates are slidably connected to the arc surface of the connecting rod.

[0006] The aforementioned components achieve the following effects: By incorporating an adjustment device, the operator can quickly assemble and disassemble the cylindrical compartment and baffle. Through the cooperation of components such as the fixing groove, locking groove, fixing block, spring, and cylindrical rod, the cylindrical compartment can be quickly snapped and fixed inside the placement cylinder, allowing the baffle on the cylindrical compartment to quickly cover one end of the placement cylinder. Simultaneously, with the help of the threaded rod and ring block linkage structure, the operator can rotate the shaft to drive the ring block on the threaded rod to rotate, which in turn drives the connecting plate to rotate. The rotating connecting plate presses the connecting rod back within the arc-shaped hole, and then the connecting rod drives the cylindrical rod to disengage from the locking groove, releasing the cylindrical compartment from its fixation. The rapid assembly and disassembly through the cooperation of these components allows for faster disassembly and replacement of the foil roll, resulting in higher efficiency.

[0007] Preferably, the inner wall of the placement cylinder has two positioning grooves, and the arc surface of the circular compartment is fixedly connected to two positioning blocks, which are slidably connected to the inner wall of the positioning grooves.

[0008] The effect achieved by the above components is as follows: by setting a positioning groove on the inner wall of the placement cylinder, fixing the positioning block on the arc surface of the cylindrical container, and sliding the positioning block with the inner wall of the positioning groove, a precise guiding and positioning structure can be formed when the cylindrical container is inserted into the placement cylinder, ensuring that the cylindrical container slides smoothly along a fixed trajectory and avoiding deviation or shaking during the insertion process. At the same time, it can accurately align the fixing block with the fixing groove, the cylindrical rod with the slot, and other components, thereby improving the stability of the cylindrical container after installation.

[0009] Preferably, the arc surface of the rotating shaft is provided with a plurality of strip grooves, and the plurality of strip grooves are evenly distributed in a circumferential array on the arc surface of the rotating shaft.

[0010] The effect achieved by the above components is that the groove can increase the friction on the surface of the shaft, making the operator's hand grip more firmly when rotating the shaft, less prone to slipping, and making the operation more labor-saving and convenient.

[0011] Preferably, the front end of the round rod is arc-shaped, and the size of the positioning block is adapted to the size of the positioning groove.

[0012] The effects achieved by the above-mentioned components are as follows: the front end of the round rod is arc-shaped. When the round chamber is inserted into the placement cylinder, this arc-shaped design can play a guiding role, allowing the round rod to slide into the slot more smoothly, reducing the difficulty of operation. At the same time, when the round rod contacts the slot, the arc-shaped front end can reduce the friction and collision loss between the two, reduce the degree of wear, and extend the service life of the round rod and the slot.

[0013] Preferably, the surface of the winding machine body is provided with a protective device, the protective device including a U-shaped block, the U-shaped block being fixedly connected to the surface of the winding machine body, a fixing rod being fixedly connected to the inner wall of the U-shaped block, a rotating block being rotatably connected to the arc surface of the fixing rod, a transparent protective plate being fixedly connected to the surface of the rotating block, a screw being fixedly connected to the upper surface of the U-shaped block, an arc plate being threadedly connected to the arc surface of the screw, and the arc plate abutting against the upper surface of the transparent protective plate.

[0014] The aforementioned components achieve the following effects: the protective device, through a rotating structure composed of a U-shaped block, a fixed rod, and a rotating block, allows for flexible opening and closing of the transparent protective plate. This allows for convenient opening when the information screen needs to be operated without affecting normal use. Furthermore, the fastening assembly consisting of a screw and an arc-shaped plate secures the transparent protective plate, effectively protecting it from flying debris and dust during processing, as well as external impacts. This provides comprehensive protection for the information screen, preventing damage from external forces or dust accumulation that could affect its display and operational performance. It ensures the long-term stable operation of the information screen and provides reliable assurance for the operation and information display of the winding machine itself.

[0015] Preferably, the arc surface of the fixing rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the U-shaped block and the rotating block, respectively.

[0016] The effect achieved by the above components is that when the transparent protective plate is released from its fixation, the torque of its torsion spring will drive the rotating block, which in turn will drive the transparent protective plate to rotate and open quickly, thus improving the convenience of the device.

[0017] Preferably, a sealing gasket, which is made of silicone rubber, is fixedly connected to the lower surface of the transparent protective plate.

[0018] The effect achieved by the above components is as follows: The silicone rubber sealing gasket, utilizing the good elasticity and flexibility of silicone rubber, can tightly adhere to the surface of the winding machine body when the protective plate is closed, filling the gap between the protective plate and the equipment, effectively preventing dust, debris, oil and other impurities from entering, enhancing the sealing performance of the protective device, and providing more rigorous protection for the information screen.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting an adjustment device, the operator can quickly disassemble and assemble the circular bin and the baffle. Through the cooperation of components such as the fixing groove, the locking groove, the fixing block, the spring, and the circular rod, the circular bin can be quickly locked and fixed inside the placement cylinder, thereby quickly allowing the baffle on the circular bin to cover one end of the placement cylinder. At the same time, with the help of the linkage structure such as the threaded rod and the ring block, the operator can rotate the shaft to drive the ring block on the threaded rod to rotate, which in turn drives the connecting plate to rotate. The rotating connecting plate presses the connecting rod back in the arc-shaped hole, and then the connecting rod drives the circular rod to disengage from the locking groove, releasing the fixing of the circular bin. The quick disassembly and assembly through the cooperation of various components makes it faster and more efficient to remove and replace the foil roll.

[0021] 2. In this utility model, the protective device utilizes a rotating structure composed of a U-shaped block, a fixed rod, and a rotating block to enable the transparent protective plate to open and close flexibly. It can be easily opened when the information screen needs to be operated without affecting the normal use of the equipment. The fastening assembly consisting of a screw and an arc-shaped plate firmly fixes the transparent protective plate, effectively resisting flying debris and dust during processing, as well as external impacts. This provides comprehensive protection for the information screen, preventing damage from external forces or dust accumulation that could affect its display and operational performance. It ensures the long-term stable operation of the information screen and provides reliable assurance for the operation and information display of the winding machine. Attached Figure Description

[0031] Reference Figures 1-8As shown, this utility model provides a technical solution: a winding machine for processing aluminum electrolytic capacitors, including a winding machine body 1, an information screen 2 mounted on the surface of the winding machine body 1, a placement cylinder 3 mounted on the surface of the winding machine body 1, a circular chamber 4 slidably connected inside the placement cylinder 3, a baffle 5 fixedly connected to the arc surface of the circular chamber 4, and an adjustment device 6 provided on the inner wall of the placement cylinder 3. By setting the adjustment device 6, the effect of facilitating quick disassembly and assembly of the circular chamber 4 and the baffle 5 by the operator is achieved. This is achieved through a fixing groove 601, a slot 602, a fixing block 603, a spring 605, and a circular... The cooperation of components such as rod 606 allows the cylindrical compartment 4 to be quickly snapped and fixed inside the placement cylinder 3, thereby quickly allowing the baffle 5 on the cylindrical compartment 4 to cover one end of the placement cylinder 3. At the same time, with the help of the linkage structure such as threaded rod 607 and ring block 611, the operator can rotate the rotating shaft 608 to drive the ring block 611 on the threaded rod 607 to rotate, thereby driving the connecting plate 612 to rotate. The rotating connecting plate 612 presses the connecting rod 610 back into the arc hole 609. Then the connecting rod 610 drives the cylindrical rod 606 to disengage from the slot 602 and release the fixing of the cylindrical compartment 4. The quick assembly and disassembly of various components allows for faster and more efficient removal and replacement of foil rolls. The surface of the winding machine body 1 is equipped with a protective device 7. The protective device 7, through a rotating structure composed of a U-shaped block, a fixing rod 72, and a rotating block 73, can flexibly open and close the transparent protective plate 74. It can be easily opened when the information screen 2 needs to be operated without affecting normal use. The fastening assembly composed of the screw 75 and the arc plate 76 can fix the transparent protective plate 74, so that the transparent protective plate 74 can effectively resist the flying debris and dust during processing, as well as the impact of external collisions, protecting the information screen 2 in all aspects and preventing it from being damaged by external forces or affected by dust accumulation, thus ensuring the long-term stable operation of the information screen 2 and providing reliable protection for the operation and information display of the winding machine body.

[0032] The specific settings and functions of its adjustment device 6 and protection device 7 will be explained in detail below.

[0033] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in this embodiment: the adjusting device 6 includes a fixing groove 601, which is formed on the inner wall of the placement cylinder 3. Two slots 602 are formed on the inner wall of the fixing groove 601. A fixing block 603 is fixedly connected to one end of the circular chamber 4. The fixing block 603 is slidably connected to the inner wall of the fixing groove 601. Two circular grooves 604 are formed on the arc surface of the fixing block 603. Springs 605 are fixedly connected to the inner walls of both circular grooves 604. A circular rod 606 is fixedly connected to the ends of the two springs 605 that are far apart from each other. The circular rod 606 is slidably connected to the inner wall of the circular groove 604. The size of the circular rod 606 is adapted to the size of the slots 602. A screw is rotatably connected inside the circular chamber 4. The threaded rod 607 has a rotating shaft 608 fixedly connected to one end. A fixing block 603 has two arc-shaped holes 609 near the rotating shaft 608. A connecting rod 610 is slidably connected to the inner wall of the arc-shaped holes 609. The connecting rod 610 is fixedly connected to the arc surface of the round rod 606. A ring block 611 is threadedly connected to the arc surface of the threaded rod 607. Two connecting plates 612 are fixedly connected to the arc surface of the ring block 611. The connecting plates 612 are slidably connected to the arc surface of the connecting rod 610. Two positioning grooves 614 are provided on the inner wall of the placement cylinder 3. Two positioning blocks 615 are fixedly connected to the arc surface of the circular chamber 4. The positioning blocks 615 are connected to the inner wall of the positioning grooves 614. The wall sliding connection, by setting a positioning groove 614 on the inner wall of the placement cylinder 3, and fixing the positioning block 615 on the arc surface of the cylindrical chamber 4, and the positioning block 615 slidingly connected to the inner wall of the positioning groove 614, can form a precise guiding positioning structure when the cylindrical chamber 4 is inserted into the placement cylinder 3, ensuring that the cylindrical chamber 4 slides smoothly along a fixed trajectory and avoiding displacement or shaking during insertion. At the same time, it can accurately align the fixing block 603 with the fixing groove 601, the round rod 606 with the slot 602, and other components, improving the stability of the cylindrical chamber 4 after installation. The arc surface of the rotating shaft 608 is provided with several strip grooves 613, which are evenly distributed in a circumferential array on the arc surface of the rotating shaft 608. 13 can increase the friction on the surface of the rotating shaft 608, making the operator's hand grip more secure and less prone to slipping when rotating the rotating shaft 608, making operation more labor-saving and convenient. The front end of the round rod 606 is arc-shaped, and the size of the positioning block 615 matches the size of the positioning groove 614. The arc-shaped front end of the round rod 606 can guide the round cylinder 4 when it is inserted into the placement cylinder 3, making the round rod 606 slide into the slot 602 more smoothly, reducing the difficulty of operation. At the same time, when the round rod 606 contacts the slot 602, the arc-shaped front end can reduce the friction and collision loss between the two, reduce the degree of wear, and extend the service life of the round rod 606 and the slot 602.

[0034] Reference Figure 7 and Figure 8As shown, specifically, the protective device 7 includes a U-shaped block 71, which is fixedly connected to the surface of the winding machine body 1. A fixing rod 72 is fixedly connected to the inner wall of the U-shaped block 71. A rotating block 73 is rotatably connected to the arc surface of the fixing rod 72. A transparent protective plate 74 is fixedly connected to the surface of the rotating block 73. A screw 75 is fixedly connected to the upper surface of the U-shaped block 71. An arc-shaped plate 76 is threadedly connected to the arc surface of the screw 75. The arc-shaped plate 76 abuts against the upper surface of the transparent protective plate 74. Two torsion springs 77 are sleeved on the arc surface of the fixing rod 72. The two ends of the torsion springs 77 are fixedly connected to the U-shaped block 71 and the rotating block 73, respectively. When the transparent protective plate 74 is released from its fixation, the torque of its torsion spring 77 will drive the rotating block 73, which in turn will drive the transparent protective plate 74 to rotate and open quickly, improving the convenience of the device. A sealing gasket 78 is fixedly connected to the lower surface of the transparent protective plate 74. The sealing gasket 78 is made of silicone rubber. The silicone rubber sealing gasket 78 utilizes the good elasticity and flexibility of silicone rubber. When the protective plate is closed, it can tightly fit the surface of the winding machine body 1, fill the gap between the protective plate and the equipment, effectively prevent dust, debris, oil and other impurities from entering, enhance the sealing performance of the protective device 7, and provide more rigorous protection for the information screen 2.

[0035] Working principle: When the cylindrical cartridge 4 needs to be installed, the cylindrical cartridge 4 can be smoothly inserted into the placement cylinder 3 along a fixed trajectory through the cooperation of the positioning block 615 and the positioning groove 614, ensuring accurate alignment of components such as the fixing block 603 and the fixing groove 601, and the cylindrical rod 606 and the slot 602. During the insertion process, the arc-shaped design of the front end of the cylindrical rod 606 plays a guiding role. When the cylindrical rod 606 is aligned with the slot 602, the elastic force of the spring 605 will drive the cylindrical rod 606 to automatically insert into the inner wall of the slot 602, thereby realizing the rapid fixation of the cylindrical cartridge 4 in the placement cylinder 3. Subsequently, the baffle 5 on the cylindrical cartridge 4 also covers one end of the placement cylinder 3. When the cylindrical cartridge 4 needs to be disassembled, the operator rotates the rotating shaft 608. The strip groove 613 on the surface of the rotating shaft 608 increases the grip friction, facilitating precise operation. The rotation of the shaft 608 drives the threaded rod 607 to rotate synchronously, causing the annular block 611 threaded onto the threaded rod 607 to rotate. The annular block 611 drives the connecting plate 612 to rotate. During rotation, the connecting plate 612 presses against the connecting rod 610, causing it to retract within the arc-shaped hole 609. This, in turn, causes the round rod 606 to overcome the elastic force of the spring 605 and disengage from the slot 602. At this point, the fixed state of the round hopper 4 is released, and the operator can easily slide the round hopper 4 out of the placement cylinder 3, thus achieving quick removal and replacement of the foil roll. The entire process, through the precise linkage and cooperation between various components, achieves convenient disassembly and assembly and accurate positioning of the round hopper 4, significantly improving production efficiency.

[0036] When information screen 2 needs protection, the operator can push the transparent protective plate 74 to rotate the rotating block 73 around the fixed rod 72 until the transparent protective plate 74 covers the information screen 2. At this time, the silicone rubber sealing gasket 78 on the lower surface of the transparent protective plate 74 adheres tightly to the surface of the winding machine body 1 due to its good elasticity and flexibility, filling the gaps. Then, the screw 75 is rotated to make the threaded arc plate 76 press down on the transparent protective plate 74, effectively resisting the flying debris and dust during processing, as well as external impacts, providing all-round protection for the information screen 2. When the information screen 2 needs to be operated, the screw 75 is rotated in the opposite direction to release the pressure of the arc plate 76 on the transparent protective plate 74. At this time, the torsion spring 77 releases torque to drive the rotating block 73 to rotate, thereby making the transparent protective plate 74 rotate and open quickly without the need for manual full force to flip it, improving the convenience of operation. The entire process utilizes the elastic force of the torsion spring 77, the tight fit between the screw 75 and the arc plate 76, and the sealing properties of the silicone rubber gasket 78 to achieve rapid opening and closing and tight protection of the transparent protective plate 74, providing a safety guarantee for the use of the information screen 2.
