Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrode foil riveting technology, specifically relating to a flexible adjustable aluminum electrode foil riveting structure. Background Technology

[0002] In the production process of aluminum electrode foil, the manufacturing of electroforming foil plays a crucial role. The quality of the electroforming foil directly affects not only the performance parameters of the aluminum electrode foil, such as capacitance, loss, and leakage current, but also determines its reliability and service life in electronic components. However, in the production process of electroforming foil, it is necessary to rivet and fix the electroforming foils together.

[0003] A utility model patent with patent authorization announcement number CN202142427U discloses an aluminum foil riveting production equipment, including an upper riveting mold assembly, a lower riveting mold assembly, an upper riveting mold, and a lower riveting mold. The upper riveting mold and the lower riveting mold are used to set negative aluminum foil, guide foil, and pad foil. The lower riveting mold assembly is provided with a guide foil bracket and a cylinder assembly for controlling the guide foil bracket. The guide foil bracket is located below the pad foil. Both the guide foil and the pad foil are located below the negative aluminum foil, and the guide foil is located between the negative aluminum foil and the pad foil.

[0004] However, the existing aluminum electrode foil riveting structure also has certain defects. First, the positions of the puncture needle and puncture needle plate used in the existing aluminum electrode foil riveting structure are mostly fixed, which makes it difficult to flexibly adjust the puncture needle and makes it unsuitable for riveting aluminum electrode foils of different thicknesses. Secondly, although existing aluminum electrode foil riveting structures mostly use bolts and other components to connect and fix the riveting structure to the riveting machine, the bolts are prone to vibration, deflection, and loosening due to external factors such as vibration and impact after long-term use. Summary of the Invention

[0005] The purpose of this utility model is to provide a flexible adjustable aluminum electrode foil riveting structure, which solves the problem that the positions of the puncture needles and puncture needle plates used in existing aluminum electrode foil riveting structures are mostly fixed, making it difficult to flexibly adjust the puncture needles and causing them to be unsuitable for riveting aluminum electrode foils of different thicknesses; and it also solves the problem that although existing aluminum electrode foil riveting structures mostly use bolts and other components to connect and fix the riveting structure to the riveting machine, the bolts are prone to vibration, deflection and loosening due to external factors such as vibration and impact after long-term use.

[0006] To achieve the above objectives, this utility model provides a flexible adjustable aluminum electrode foil riveting structure, including a support platform. The lower end of the support platform contacts four evenly distributed mounting components, and the upper end of the support platform contacts a puncture needle plate. A puncture needle is disposed inside the puncture needle plate. A flexible adjustment mechanism is jointly provided on the puncture needle plate and the support platform. Four evenly distributed screws are fixedly connected to the lower end of the support platform. The screws are slidably connected to the mounting components, and non-standard nuts are threadedly connected to the outer side of the screws, with the non-standard nuts contacting the mounting components.

[0007] The principle of this utility model is as follows: by pulling the end ear away from the fixed frame, the telescopic plate slides along the inner wall of the fixed frame, causing the end plate to move. When the spring deforms, it eventually causes the limiting post to disengage from the limiting hole, which can push the support platform to contact the mounting component, allowing the screw to pass through the mounting component and push the non-standard nut to contact the screw. By rotating the non-standard nut, it can be installed under the threaded connection, making the non-standard nut in close contact with the mounting component. Then, by releasing the end ear, the spring returns to its original deformation, pushing the telescopic plate to slide along the inner wall of the fixed frame, thereby causing the limiting post to insert into the limiting hole on the surface of the non-standard nut, allowing the non-standard nut to be inserted and used, avoiding the problems of vibration, deflection, and loosening of the non-standard nut. The telescopic end is moved by the hydraulic cylinder, which can push the puncture needle plate to move and flexibly adjust the position of the puncture needle. When the puncture needle plate moves, it can drive the moving ear to move, so that the telescopic rod drives the guide plate to slide along the surface of the guide rod, and guides the movement of the puncture needle plate to ensure the stability of the movement of the puncture needle plate. Under the deformation of the second spring, the telescopic rod can keep the guide plate in contact with the guide rod to ensure good guiding characteristics of the guide plate.

[0008] The beneficial effects of this utility model are as follows: This solution, through the action of screws, mounting components, non-standard nuts, and other structures, can fix the riveting structure to riveting machines and other machinery. Under the action of limiting holes, limiting posts, springs, and other structures, the non-standard nuts can be inserted and limited, avoiding the problem of loosening of non-standard nuts due to vibration and impact, thus ensuring the long-term stability of the riveting structure. Through the action of piercing needle plates, piercing needles, and other structures, and in conjunction with the rolling mechanism of existing riveting machines, stacked aluminum electrode foils can be pierced. Under the action of hydraulic cylinders, moving ears, guide rods, and other structures, the piercing needle plates can be moved, and the position of piercing needles can be flexibly adjusted to adapt to aluminum electrode foils of different thicknesses. Under the action of springs and guide plates, a good guiding effect on the piercing needle plates can be ensured, so that the piercing needle plates are in a stable moving state.

[0009] Furthermore, the surface of the non-standard nut is provided with multiple limiting holes arranged in a circular array. The surface of the support platform is fixedly connected with four evenly distributed fixing frames. The vertical part of each fixing frame is slidably connected with a telescopic plate. The end face of the telescopic plate near the non-standard nut is fixedly connected with a limiting post. The limiting post is slidably connected to one of the limiting holes. An end plate is fixedly sleeved on the outside of the telescopic plate. A spring is provided on the outside of the telescopic plate. Through the cooperation of the non-standard nut, screw and other structures, the support platform and the installation component can be fixed. Under the action of the limiting post, limiting holes and other structures, the non-standard nut can be limited, avoiding the vibration deflection and loosening of the non-standard nut.

[0010] Furthermore, the other end of the telescopic plate is fixedly connected to an end lug, which contacts the vertical part of the fixing frame. The end lug is made of rubber. The end lug facilitates the movement of the telescopic plate by pulling it, and the rubber material has good usability.

[0011] Furthermore, one end of the spring is fixedly connected to the end plate, and the other end of the spring is fixedly connected to the vertical part of the fixing frame. The spring is made of spring steel. The end plate can be connected and used through the setting of the spring. The spring steel material has good fatigue resistance and high elastic limit.

[0012] Furthermore, the flexible adjustment mechanism includes a hydraulic cylinder. A hydraulic cylinder is fixedly installed on the inner top of the support platform. The telescopic end of the hydraulic cylinder is slidably connected to the support platform and fixedly connected to the puncture needle plate. Two symmetrically distributed guide rods are fixedly connected to the upper end of the support platform. Two symmetrically distributed movable ears are fixedly connected to the surface of the puncture needle plate. The movable ears are slidably connected to the guide rods. Two symmetrically distributed telescopic rods are slidably connected to the inner wall of each movable ear. A guide plate is fixedly connected to the end face of each telescopic rod near the guide rod. The guide plate is slidably connected to the guide rod. A connecting plate is fixedly connected to the other end of each telescopic rod. A spring is provided on the outer side of each telescopic rod. Through the telescopic action of the hydraulic cylinder, the puncture needle plate can be driven to move, allowing for flexible adjustment of its position. With the cooperation of the guide plate and guide rods, the puncture needle plate can be guided to ensure its stability.

[0013] Furthermore, multiple guide plates are provided, which are symmetrically distributed on the guide rod. The guide plates are made of graphite. By setting the guide plates, they can work with the guide rod and the movable lug to restrict the movement of the puncture needle plate. Graphite material has good low resistance.

[0014] Furthermore, one end of the second spring is fixedly connected to the connecting plate, and the other end of the second spring is fixedly connected to the movable ear.

[0019] like Figure 1 , Figure 2 , Figure 4 As shown, the other end of the telescopic plate 10 is fixedly connected to an end lug 12, which contacts the vertical part of the fixing frame 9. The end lug 12 is made of rubber. The end lug 12 facilitates the movement of the telescopic plate 10 by pulling it, and the rubber material has good usability.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a flexible adjustment mechanism 5 is jointly provided on the puncture needle plate 3 and the support platform 1. The flexible adjustment mechanism 5 includes a hydraulic cylinder 50. The hydraulic cylinder 50 is fixedly installed on the top inner side of the support platform 1. The telescopic end of the hydraulic cylinder 50 is slidably connected to the support platform 1, and the telescopic end of the hydraulic cylinder 50 is fixedly connected to the puncture needle plate 3. Two symmetrically distributed guide rods 51 are fixedly connected to the upper end of the support platform 1. Two symmetrically distributed movable ears 52 are fixedly connected to the surface of the puncture needle plate 3. The movable ears 52 are slidably connected to the guide rods 51. The inner wall of each movable ear 52 is slidably connected to two... Symmetrically distributed telescopic rods 53, each telescopic rod 53 has a guide plate 54 fixedly connected to the end face near the guide rod 51, the guide plate 54 is slidably connected to the guide rod 51, and the other end of each telescopic rod 53 is fixedly connected to a connecting plate 55.

With the cooperation of the guide plate 54 and the guide rod 51, the puncture needle plate 3 can be moved and guided to ensure the stability of the movement of the puncture needle plate 3.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, multiple guide plates 54 are provided, and the multiple guide plates 54 are symmetrically distributed on the guide rod 51.

[0022] The specific implementation process of this utility model is as follows: By pulling the end ear 12 to move away from the fixed frame 9, the telescopic plate 10 is driven to slide along the inner wall of the fixed frame 9, so that the end plate 13 moves and the spring 14 deforms, and finally the limiting post 11 is driven to disengage from the limiting hole 8, which can push the support platform 1 to contact the mounting component 2, so that the screw 6 passes through the mounting component 2 and pushes the non-standard nut 7 to contact the screw 6.

When the puncture needle plate 3 moves, it can drive the moving ear 52 to move, so that the telescopic rod 53 drives the guide plate 54 to slide along the surface of the guide rod 51, and guides the movement of the puncture needle plate 3 to ensure the stability of the movement of the puncture needle plate 3. Under the deformation of the second spring 56, the telescopic rod 53 can always keep the guide plate 54 in contact with the guide rod 51 to ensure the good guiding characteristics of the guide plate 54.

The hydraulic cylinder 50, moving lug 52, and guide rod 51 allow for movement of the piercing needle plate 3 and flexible adjustment of the position of the piercing needle 4 to accommodate aluminum electrode foils of different thicknesses. The spring 56 and guide plate 54 ensure good guidance for the piercing needle plate 3, keeping it in a stable moving state.
