Description

Technical Field

[0001] This application relates to the field of battery tab punching technology, and in particular to a tooling for punching tabs of a battery flexible connector. Background Technology

[0002] With the rapid development of the new energy industry, various types of batteries are widely used in electric vehicles, energy storage systems, and 3C products. As a key component in battery packs that enables electrical connections, the performance of the battery flexible connector directly affects the overall stability and safety of the battery pack. The tabs, as an important part of the connection between the battery flexible connector and external circuitry, require high-quality punching for both electrical and mechanical performance.

[0003] A search revealed that patent application number CN202222784196.0 discloses a battery tab punching machine, comprising a base plate, two sets of columns fixedly connected to the upper surface of the base plate, a top plate fixedly connected to the top of the two sets of columns, two electric push rods mounted on the bottom surface of the top plate, a fixed plate fixedly connected to the bottom ends of the two electric push rods, two sets of punches mounted on the bottom surface of the fixed plate, a placement plate fixedly connected to the upper surface of the base plate, two sets of punch holes formed on the upper surface of the placement plate, and a through groove formed on the upper surface of the base plate. This battery tab punching machine, through the cooperation of the electric push rods, fixed plate, punches, placement plate, and punch holes, utilizes the operation of the electric push rods to push the fixed plate downwards, allowing the punches to pass through the tabs and enter the punch holes, thus completing the punching work on the tabs. After punching, the debris generated during punching can enter the collection box, improving the punching efficiency of the operator and reducing costs.

[0004] However, the device has some shortcomings in use. It does not properly position the tabs when punching holes, which causes the tabs to shift during the punching process, resulting in a decrease in punching quality. At the same time, debris remains on the surface of the placement platform during the punching process, and failure to clean it in time will cause the punching to become blocked.

[0023] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0024] This application discloses a punching fixture for the tabs of a battery flexible connector, including a base 1, a placement plate 2 on the top of the base 1, positioning structures at the left and right ends of the top of the placement plate 2, two symmetrical support frames 4 on the top of the base 1, a top plate 5 mounted on the top of the two support frames 4, two symmetrical fixing plates 6 on the top of the base 1, a cleaning component between the support frames 4 and the fixing plates 6, a collection box 7 in a groove on the top of the base 1, a stamping cylinder 18 mounted on the top of the top plate 5, a mounting base 19 connected to the bottom of the stamping cylinder 18, and a punch 20 at the bottom of the mounting base 19.

[0025] refer to Figure 2 and Figure 3The positioning structure includes two symmetrical positioning blocks 8 installed on the top of the placement plate 2. A slider 9 is provided at the bottom of the two positioning blocks 8, and the slider 9 slides within a symmetrical groove 10 opened on the top of the placement plate 2. Two sets of symmetrical limiting grooves 11 are provided on the two positioning blocks 8. These two sets of limiting grooves 11 correspond to two rows of fixing holes 12 located at the edge of the groove 10 on the top of the placement plate 2. Fixing bolts 13 are also provided within the two sets of limiting grooves 11. One end of each fixing bolt 13 is fitted into one of the two rows of fixing holes 12 on the top of the placement plate 2. The top of the placement plate 2 is located within the two... A punching hole 3 is also provided between the positioning blocks 8. More specifically, when positioning the electrode tab, the two positioning blocks 8 are moved so that they move towards each other along the sliding groove 10 opened on the top of the placement plate 2 via the slider 9 set at the bottom. This makes one side of the two positioning blocks 8 aligned and fitted with the electrode tab. Then, the fixing bolt 13 passes through the limiting groove 11 opened on the positioning block 8 and matches one of the two rows of fixing holes 12 set on the top of the placement plate 2, thereby fixing the two positioning blocks 8 and positioning the electrode tab. This avoids displacement during the punching process and improves the convenience of the positioning operation.

[0026] refer to Figure 2 and Figure 4 The cleaning assembly includes two sliding rods 14 fixedly connected between the support frame 4 and the side wall of the fixed plate 6. A movable plate 15 is slidably mounted on the two sliding rods 14. A handle 16 is provided at one end of the movable plate 15. A cleaning brush 17 is also installed at the bottom of the movable plate 15. The bottom of the cleaning brush 17 is in contact with the top of the placement plate 2. More specifically, by fixing the two sliding rods 14 between the support frame 4 and the side wall of the fixed plate 6, the movable plate 15 is slidably mounted on the two sliding rods 14. The cleaning brush 17 at the bottom of the movable plate 15 can clean the debris remaining on the top of the placement plate 2 after the electrode tab is punched. At this time, by pushing the handle 16 at one end of the movable plate 15, the movable plate 15 slides back and forth along the two sliding rods 14, so that the cleaning brush 17 at the bottom of the movable plate 15 can clean the debris on the top of the placement plate 2 and sweep the debris into the collection box 7, thereby improving the cleanliness of the top of the placement plate 2, avoiding blockage of the top punching hole 3, and improving the punching quality.

[0027] The implementation principle of the electrode tab punching fixture for a battery flexible connector in this application embodiment is as follows: During use, the electrode tab to be punched is placed on top of the placement plate 2. Two positioning blocks 8 are moved so that one side aligns with both sides of the electrode tab. Then, the fixing bolt 13 passes through the limiting groove 11 opened on the positioning block 8 and matches one of the two rows of fixing holes 12 provided on the top of the placement plate 2, thus fixing the two positioning blocks 8 and positioning the electrode tab, preventing displacement during punching and improving the convenience of the positioning operation. Then, the stamping cylinder is driven. 18 drives the mounting base 19 to move downwards, so that the punch 20 at the bottom of the mounting base 19 punches the electrode tab. After punching the electrode tab, there will be debris remaining on the top of the placement plate 2. At this time, by pushing the handle 16, the moving plate 15 is moved back and forth along the two slide rods 14, so that the cleaning brush 17 at the bottom of the moving plate 15 can clean the debris on the top of the placement plate 2 and sweep the debris into the collection box 7, thereby improving the cleanliness of the top of the placement plate 2, avoiding blockage of the top punching hole 3, and improving the punching quality.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
