Description

Technical Field

[0001] This utility model relates to the field of supercapacitor technology, and in particular to an assembly tooling for a supercapacitor, specifically a riveting tooling for the electrode conductor foil strips and cover plate electrode posts of a welded supercapacitor. Background Technology

[0002] Supercapacitors, as a new type of energy storage device, have advantages such as high power density, long cycle life, and fast charging and discharging speed, and have broad application prospects in electric vehicles, smart grids, consumer electronics and other fields.

[0003] Currently, in the product structure of welded supercapacitors, the riveting of the electrode conductor foil (specifically, the semi-finished product consisting of the electrode conductor foil and a washer plate punched together, which is a conductor foil with a washer plate) to the cover plate terminals (including positive and negative terminals) is the key link connecting the two. Due to the special riveting position, the complexity of the implementation method, and the need to ensure the concentricity of the riveting between the electrode conductor foil and the cover plate, mechanical positioning riveting is currently widely used to achieve the riveting fixation of the electrode conductor foil and the cover plate. During the riveting process, the concentricity and fitting accuracy of the electrode guide foil and the cover plate are the core factors affecting the riveting quality. It is worth noting that before riveting, each layer of the electrode guide foil is relatively thin (usually only 0.1~0.2 mm) and narrow (usually only 5~8 mm). There are four relatively overlapping electrode guide foils for both the positive and negative electrodes, and each pair (2 foils) is equipped with a washer (i.e., a gasket). Therefore, when riveting the electrode guide foil and the cover plate over such a narrow contact area, if the concentricity of the riveting is off or the fixed position of the cover plate is shifted, it can easily lead to poor riveting results, directly causing riveting eccentricity, and thus increasing scrap and defective costs. However, there is currently no tooling that can reliably rivet the conductive foil strips (with washer strips) on the electrode assembly of a supercapacitor (such as a sputter-type supercapacitor) to the cover plate electrode post, ensuring the quality of the riveting.

[0013] See Figures 1a to 1b , Figures 2 to 6 , Figures 7a to 7b , Figures 8 to 9 This utility model provides an assembly fixture for a supercapacitor, which is a riveting fixture for the semi-finished product of the electrode group conductive foil strip and washer sheet punched with holes and the cover electrode post of the welded supercapacitor. The fixture includes: a riveting mechanism. The riveting mechanism includes a riveting spring 1, a riveting vertical plate 2, a T-shaped block 3, a riveting upper plate 4, a riveting bottom plate 5, a guide rail connecting block 6, a riveting fixture pad 7, a riveting fixture 8, a riveting sleeve 9, a riveting pin 10, a guide rail slider 13, a hydraulic cylinder 14, and a negative embossed riveting pin 15. Among them, the riveting upper plate 4 and the riveting bottom plate 5 are arranged vertically spaced and parallel to each other; The upper and lower ends of the riveting vertical plate 2 are respectively fixed to the rear ends of the riveting upper plate 4 and the riveting bottom plate 5; The front side of the riveted vertical plate 2 is fixedly provided with vertically distributed guide rails 130; A guide rail slider 13 is vertically slidable on the guide rail 130; It should be noted that the sliding fit connection structure between the guide rail and the slider is a common existing structure, and will not be described in detail here.

[0014] A guide rail connecting block 6 is provided on the front side of the guide rail slider 13; A hydraulic cylinder 14 is provided on the top of the riveted upper plate 4; The output end (i.e., piston rod, or telescopic rod) on the lower side of the hydraulic cylinder 14 is connected to the guide rail connecting block 6 after passing vertically through the through hole reserved on the riveted upper plate 4. A T-shaped block 3 is embedded in the lower front end of the guide rail connecting block 6; The bottom of the T-shaped block 3 is provided with two vertically distributed rivet pins 10; The upper end of a rivet spring 1 is sleeved on the outside of each rivet pin 10; Each riveting spring 1 has a riveting sleeve 9 fixed at its bottom end; A riveting fixture pad 7 is provided on the top of the riveting base plate 5; A riveting fixture 8 is provided on the top of the riveting fixture pad 7.

[0015] In this utility model, specifically, the bottom surface of the T-shaped block 3 is set at a right angle to the front side surface; The front side of the T-shaped block 3 is embedded in the lower part of the front side wall of the guide rail connecting block 6; The bottom surface of T-shaped block 3 is embedded in the bottom surface of guide rail connecting block 6; The bottom surface of the T-block 3 is fixedly connected to the top end of the rivet pin 10; It should be noted that, in this utility model, specifically, the tops of the riveting spring 1 and the riveting pin 10 are fixed to the bottom surface of the T-shaped block 3 by screws. The main purpose of this is to prevent the riveting pin 10 from being pushed out by the reaction force during the vertical downward riveting process of the riveting pin to the electrode guide foil strip and the cover electrode post. Simultaneously, it effectively ensures that the hydraulic cylinder 14 drives the guide rail slider 13 to push the riveting pin 10 vertically downward, so that the riveting pin 10 rivets the electrode guide foil strip and the cover electrode post, forming a stable fixed state. In this utility model, specifically, the riveting mechanism further includes a connecting block 11 and a cylinder connector 12; The telescopic rod (i.e. the piston rod at the output end) on the lower side of the hydraulic cylinder 14 passes vertically through the through hole reserved on the riveted upper plate 4 and is connected to the top of the guide rail connecting block 6 through the cylinder connector 12. The cylinder connector 12 is fixedly mounted on the top of the guide rail connecting block 6; A connecting block 11 is provided at the top left and right ends of the guide rail connecting block 6; Connecting blocks 11 are located on both sides of cylinder connector 12 and are used for overall clamping and follow-up. In this utility model, the tooling also includes a riveting machine frame; The riveting machine frame includes an upper panel 19, a base plate 20, and feet 22; The upper panel 19 and the bottom plate 20 are arranged parallel to each other vertically. At the four corners of the bottom of the base plate 20, a foot cup 22 is provided; The riveting mechanism (specifically the riveting base plate 5) is placed on top of the upper panel 19 of the riveting machine frame and fixedly connected. In practice, a riveted upper pad 16 is provided at the center of the upper panel 19; The riveting base plate 5, which is equipped with a riveting mechanism, is riveted to the top of the upper pad plate 16.

[0016] In practice, each foot cup 22 is provided with a caster 23 at an adjacent position; The caster 23 is fixedly connected to the bottom of the base plate 20 via the foot plate 21.

[0017] In practice, the left and right sides of the top panel 19 and the bottom plate 20 are respectively fixed to the top and bottom ends of a frame 17; The rear sides of the upper panel 19 and the bottom plate 20 are fixed to the upper and lower ends of a sealing plate 18; In practice, a foot control valve 31 for controlling the cylinder's movement is installed on the base plate 20. The foot control valve is a conventional accessory for cylinders and is a well-known and mature technology, so it will not be described in detail here.

[0018] In practice, a booster 24 is also installed on the base plate 20, which is connected to the cylinder to increase the cylinder's intake pressure. The booster is a conventional cylinder accessory and is a well-known and mature technology, so it will not be described in detail here.

[0019] It should be noted that, for this utility model, the riveting machine frame includes a riveting pad 16, a frame 17, a sealing plate 18, a top panel 19, a bottom plate 20, a foot plate 21, a foot cup 22, a caster 23, a booster 24, and a foot pedal control valve 25.

[0020] It should be noted that, for this utility model, the riveting mechanism can effectively ensure that the hydraulic cylinder 14 drives the guide rail slider 13 to push the riveting pin 10 vertically downward, so that the riveting pin 10 processes the guide foil strip 270 of the pole group and the semi-finished product with punched holes in the washer plate 28 and the cap pole post 26 to form an overall fixed state, ensuring the concentricity of the riveting and the product quality to meet the process requirements. It should be noted that, for this utility model, the riveting machine frame can prevent operators from experiencing fatigue during long-term manual operations, and to a large extent ensures the overall stability of the riveting fixture for the electrode conductor foil strips of the welded supercapacitor, the semi-finished products with punched washer plates, and the cover plate electrode posts, thus extending the service life and improving the product riveting qualification rate. In this utility model, specifically, the top of the riveting fixture 8 is used to place the cover plate 26 of the supercapacitor that needs to be riveted. The top of the cover plate 26 is provided with two cover plate poles 260 spaced apart; Two cover plate terminals 260, including one positive terminal and one negative terminal; The two rivet pins 10 and the two cover plate poles 260 are set in a vertically aligned manner.

[0021] In practice, the upper surface of the riveting fixture 8 is connected to a negative embossed riveting pin 15. The negative electrode embossed riveting pin 15 is located directly below the negative electrode post in the two cover plate posts 260.

[0022] In practice, for the semi-finished product of the conductive foil strip 270 of the electrode group 27 of the supercapacitor that needs to be riveted and the punched washer plate 28, the semi-finished product is connected to the two cover plate poles 260. Specifically, the annular washer plate 28 is fitted onto the two cover plate poles 260 of the cover plate 26.

[0023] It should be noted that the negative electrode embossing rivet pin 15 can be cylindrical in shape, with its top surface facing the negative electrode of the two cover plate electrode pins 260. Its top surface is uneven and has a pre-processed uneven pattern, which can form embossed patterns on the surface of the external object after being squeezed.

[0024] It should be noted that, Figure 5 The cover plate of the supercapacitor is placed on the riveting fixture 8 (i.e., the riveting mold). There are two riveting pins 10, which correspond to the positive and negative electrode conductive foil strips of the supercapacitor electrode group and the corresponding cover plate electrode posts, respectively, so as to realize the subsequent riveting function. Figure 8 This is a schematic diagram showing the effect after the conductive foil strips of the electrode group of the supercapacitor in this utility model are punched with the washer plate and the cap electrode post are riveted together. To better understand the technical solution of this utility model, the specific working process of this utility model is described below.

[0025] First, such as Figure 1a , Figure 1b , Figures 2 to 5 As shown, in the riveting mechanism of this utility model, the cover plate 26 of the supercapacitor (specifically the cover plate of the welded supercapacitor) is placed on the riveting fixture 8. Then, the worker manually puts each pair of conductive foil strips 270 (specifically two pairs) of the supercapacitor electrode group 27 and the semi-finished product with punched holes in the washer plate 28 onto the two cover poles 260 of the cover plate 26, so that they form an integral contact. It should be noted that for the semi-finished products with punched holes in each pair of guide foil strips 270 (specifically two pairs) and washer plates 28, one end of each pair of guide foil strips 270 (including two overlapping guide foil strips) is pre-connected to a circular washer plate 28 (the connection part can be set to correspond to the center position of the washer plate 28). The circular washer plate 28 can be fitted onto the two cap posts 260 of the cover plate 26. The guide foil strips are aligned and basically flat, forming an overlapping shape with the washer plate.

[0026] Then, the operator steps on the foot pedal (i.e., foot control valve 25), causing the riveting pin 10, riveting sleeve 9, and riveting spring 1 to move vertically downwards to their maximum stroke under the drive of the hydraulic cylinder 14 and guide rail slider 13, thus riveting and fixing the guide foil strip and cover plate pole. Simultaneously, the negative pole of the two cover plate poles is squeezed by the negative embossed riveting pin 15, resulting in embossed patterns on the surface of the negative pole of the cover plate 26. This facilitates employee identification of the negative pole position of the riveted semi-finished product, preventing mistake-proofing and facilitating subsequent production processes. Then, after the operator releases the foot pedal (i.e., foot control valve 25), the riveted supercapacitor semi-finished product (specifically, a welded-plate type supercapacitor semi-finished product) is removed from the riveting fixture 8. Based on this utility model, the one-time forming of the riveting of the conductive foil strip of the welded-plate type supercapacitor electrode group to the cover plate electrode post can be easily realized. The specific process is as follows: 1. First, place the cover in the riveting fixture; 2. The operator manually places the washer plate 28, which is connected to one end of the conductive foil strip 270 of the punched supercapacitor electrode group 27 (e.g., the soldered supercapacitor electrode group), onto the two cover plate posts 260 (specifically including the positive post and the negative post) of the cover plate 26. 3. The operator steps on the foot pedal (i.e., foot control valve 25) to make the riveting pin move vertically downward under the drive of the hydraulic cylinder and the slider, and perform overall riveting treatment on the cover plate, washer sheet and guide foil strip. 4. After the operator releases the foot pedal (i.e., foot control valve 25), the cover plate 26 and the supercapacitor electrode assembly 27 are secured. See also Figure 8 As shown.

[0027] In the subsequent product manufacturing process, once the tooling is adjusted, employees only need to place the cover plate and the punched electrode group guide foil strips (i.e., the guide foil strips 270 of the supercapacitor electrode group 27 and the semi-finished products with punched washer 28) into the riveting fixture to carry out continuous positioning manual operation production.

[0028] The above is a detailed description, with reference to an embodiment, of the riveting and fixing of the semi-finished product (completed by punching holes in the electrode group conductive foil and washer sheet) to the cover plate electrode post. This description is illustrative and not limiting. Therefore, within the field of riveting the semi-finished product (completed by punching holes in the electrode group conductive foil and washer sheet) to the cover plate electrode post of a supercapacitor, any changes and modifications that do not depart from the overall concept of this utility model should fall within the protection scope of this utility model.

[0029] Compared with the prior art, the assembly fixture for a supercapacitor provided by this utility model is a riveting fixture for connecting the conductive foil strip and the cover plate of a welded supercapacitor, which has the following beneficial technical effects: 1. Simple positioning: Employees can directly place the cover plate of the soldered supercapacitor into the anti-foolproof groove of the riveting fixture, ensuring stable positioning without any shaking. The operation is simple and suitable for positioning cover plates of various diameters. 2. Easy one-time forming of electrode group guide foil strips and cover: After the electrode group guide foil strips and cover plates are positioned, the employee steps on the foot pedal, and the riveting pin presses vertically downwards to complete the extrusion riveting and positioning of the electrode group guide foil strips and cover poles until the riveting is complete. The employee only needs to place one cover plate into the riveting fixture, and then smoothly place the washer 28 on each guide foil strip of the electrode group onto the outside of the cover plate pole and maintain stable contact, which will not affect the relative positioning of the electrode group guide foil strips and cover plates. 3. Easy off-line loading and unloading operation: The riveting fixture of this utility model can be moved at any time according to the production space requirements, and the size of the production area can be flexibly adjusted to meet the flexibility and mobility of production and the coordination of production line layout.

[0030] 4. Good extrusion contact between the electrode group's guide foil and the cover plate: The riveting pin 10 is used for riveting the electrode group's guide foil and the cover plate. Its material is tungsten steel, which can be used for a long time. The estimated service life is about 500,000 times, which can ensure the overall riveting effect between the supercapacitor electrode group's guide foil and the cover plate. Therefore, the assembly fixture for a supercapacitor provided by this utility model is a riveting fixture for connecting the conductive foil strip and the cover plate of a welded supercapacitor. It has the characteristics of simple positioning, relatively stable state, and high consistency, which makes it easy for employees to operate and can easily realize the one-time riveting positioning and fixing of the electrode group conductive foil strip and the cover plate that have been punched.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
