Description

Technical Field

[0001] This utility model relates to the field of battery cell manufacturing technology, and in particular to a dual-axis disconnect riveting device. Background Technology

[0002] The battery cell is the core component of a battery, a basic unit system capable of directly converting chemical energy into electrical energy. In the production and processing of prismatic battery cell casings, the positive and negative terminals on the cell top cover or casing are generally assembled using riveting. Because existing battery cell products are relatively large, the precision requirements for assembly are relatively low. Typically, all components are placed in a mold according to a predetermined order, and then a riveting rod is pressed down to rivet the pre-assembled components into a single structure. While experimental verification has shown that the compression of the inner and outer insulation components can reach the conventional requirement of 30%, the compression ratio of the inner and outer insulation is often random and cannot be precisely controlled.

[0003] As people increasingly pursue thinner and lighter devices, battery products are becoming smaller and smaller. With such a reduction in product size, the corresponding cover dimensions also decrease, placing significant demands on structural design and dimensional accuracy. Current commercially available riveting machines, based on preliminary testing, have shown that direct riveting leads to excessive compression of the outer insulation, easily causing cracking, while the inner insulation often suffers from insufficient compression. The riveting process can also damage the product, rendering the cover's insulation performance unacceptable. Some equipment that separately presses the inner and outer insulation components, using different mechanisms, may encounter positioning problems. Stacking multiple components can result in angular misalignment between contact surfaces, affecting the overall pressing effect. Furthermore, this increases the number of components and raises costs.

[0004] Therefore, it is necessary to provide a biaxial disconnect riveting device that can be used for riveting small-sized battery cell cover plates and has a good riveting effect. Utility Model Content

The riveting rod 42 approaches the riveting head 41 to push the riveting head 41 to slide along the forming hole 311 and rivet the battery cell cover 50 into shape.

[0032] With the above technical solution, the dual-axis disconnect riveting device 100 of this utility model includes a positioning platform 10, a riveting fixture 20, a pressing mechanism 30, and a riveting mechanism 40, all mounted on a frame 101. The positioning platform 10 has a feeding area 110 for placing the riveting fixture 20, and includes a positioning component 16 for positioning the riveting fixture 20.

The riveting rod 42 approaches the riveting head 41 to push the riveting head 41 to slide along the forming hole 311 and rivet the battery cell cover 50. In this invention, the dual-axis disconnect riveting device 100 allows the riveting fixture 20 to position small-sized battery cell cover 50. The riveting head 41 and riveting rod 42 are disconnected. As the pressing mechanism 30 actuates, the riveting head 41 remains parallel and in contact with the product, better maintaining the parallelism between the riveting head 41 and the product, resulting in a better riveting effect.

[0033] Please see Figure 2 , Figure 3 and Figures 6 to 9 In some optional embodiments, the pressing mechanism 30 includes a support plate 32, a guide assembly 33, and a pressing power assembly 34. The support plate 32 is mounted on the positioning platform 10 via the guide assembly 33, such that the support plate 32 is positioned above the riveting fixture 20. The positioning pressure plate 31 is mounted on the support plate 32 via a connecting hole 314. The output end of the pressing power assembly 34 is connected to the support plate 32. The pressing power assembly 34 actuates to drive the support plate 32 to slide along the guide assembly 33, resulting in more accurate positioning. Under the guidance of the guide assembly 33, the positioning pressure plate 31 is ensured to move vertically up and down. When the positioning pressure plate 31 moves vertically upward away from the feeding zone 110, it facilitates the placement of the riveting fixture 20 within the feeding zone 110. When the positioning pressure plate 31 moves vertically downward, it approaches and presses against the riveting position of the cell cover plate 50 to press the inner insulation member 53 onto the cover plate member 51.

[0034] Please see Figure 5 and Figure 6In some optional embodiments, the riveting fixture 20 includes a base 21 and a stop 22. The base 21 has a material groove 211 and a positioning groove 212. The battery cell cover 50 is placed in the material groove 211 and guided and positioned by positioning pins and holes for precise alignment. It is then fixed by mutual attraction components such as magnets. The stop 22 cooperates with the positioning groove 212 and covers the battery cell cover 50 to position the battery cell cover 50. The stop 22 has a positioning hole 221 that cooperates with the forming hole 311, and the riveting position of the battery cell cover 50 is aligned with the positioning hole 221. The riveting head 41 passes through the forming hole 311 and the positioning hole 221 under the action of the riveting rod 42 to rivet the battery cell cover 50 into shape. The support plate 32 has a through hole that connects to the forming hole 311. One end of the riveting head 41 in the forming hole 311 passes through the through hole so that it can be pressed by the riveting rod 42.

[0035] Please see Figures 5 to 9 In some optional embodiments, the base 21 is further provided with a first guide portion 213, and the positioning plate 31 is provided with a second guide portion 313 that cooperates with the first guide portion 213. The second guide portion 313 cooperates with the first guide portion 213 to make the positioning plate 31 approach the riveting fixture 20 along a preset trajectory and press the inner insulating member 53 onto the cover plate member 51. The provision of the mutually cooperating first guide portion 213 and second guide portion 313 enables the positioning plate 31 to slide according to the guide, without deviation under force, and with vertical force, resulting in better molding effect. For example, the first guide portion 213 is a guide hole, and the second guide portion 313 is a guide post. Or the first guide portion 213 is a guide post, and the second guide portion 313 is a guide hole. The molding hole 311 is provided with second guide portions 313 on both sides, and the base 21 is also provided with two first guide portions 213 that cooperate with the second guide portions 313. Guide components are provided on both sides of the forming hole 311, which makes the guiding and positioning more precise. Together with the guide component 33 for support, the overall force is vertical and reliable, ensuring that the force of the positioning plate 31 pressing the product is always vertically downward, ensuring that the product is compressed evenly and reducing the risk of cracking. This is also the key to controlling the compression of the inner insulation component 53.

[0036] Please see Figures 5 to 9 In some optional embodiments, a positioning protrusion 312 is provided on the positioning plate 31, and a forming hole 311 passes through the positioning protrusion 312. A groove 222 is provided on the stop block 22, and the positioning protrusion 312 presses the inner insulating member 53 onto the cover plate member 51 within the groove 222, aligning the forming hole 311 with the positioning hole 221. On the other hand, a groove 214 is provided on the base 21 to cooperate with the positioning assembly 16. The positioning assembly 16 moves close to the riveting fixture 20 and acts on the groove 214. The end of the positioning assembly 16 is located within the groove 214, making the positioning more stable and improving the positioning effect.

[0037] Please see Figure 6 and Figure 7 In some optional embodiments, the forming hole 311 includes a sliding section 3111 and a positioning section 3112. The inner diameter of the sliding section 3111 is larger than the inner diameter of the positioning section 3112, and a limiting part for limiting is formed between the sliding section 3111 and the positioning section 3112 to prevent the entire riveting head 41 from sliding out of the forming hole 311. Specifically, the riveting head 41 includes an integrally formed sliding part 411 and a forming part 412. The riveting head 41 is located inside the sliding section 3111, and one end of the sliding part 411 protrudes from the side of the sliding section 3111 away from the positioning section 3112, that is, one end of the riveting head 41 extends into the sliding section 3111 for the riveting rod 42 to press. The sliding part 411 and the sliding section 3111 fit tightly together and will not wobble or shift, resulting in good positioning effect. The rivet rod 42 acts on the sliding part 411 to make the rivet head 41 slide along the sliding section 3111 until the forming part 412 protrudes from the positioning section 3112 and acts on the cell cover plate 50. Understandably, with the cooperation of the guide assembly 33 and the first guide part 213 and the second guide part 313, the positioning block has good perpendicularity. The rivet head 41 is located inside the forming hole 311 and fits tightly with it, ensuring the perpendicularity of the rivet head 41. The part of the rivet head 41 that contacts the product always remains tightly fitted and parallel to the product along with the positioning plate 31, and the force is perpendicular. Furthermore, the rivet rod 42 acts on the rivet head 41. The rivet rod 42 only provides pressure and does not directly contact the product, reducing the work and difficulty of leveling it parallel to the product, and resulting in a better overall pressing and forming effect.

[0038] Please see Figure 10 In some optional embodiments, the riveting mechanism 40 further includes a pressure sensor 43 connected to the riveting power assembly 44, and the riveting rod 42 connected to the pressure sensor 43. The riveting power assembly 44 actuates to move the riveting rod 42 closer to the riveting head 41. The pressure sensor 43 determines the force exerted by the riveting rod 42 on the riveting head 41, thereby precisely controlling the compression amount of the outer insulating component 54. Specifically, the riveting power assembly 44 is a motor, which precisely controls the riveting action and monitors the riveting pressure in real time through the pressure sensor 43, accurately controlling the riveting amount and the compression amount of the outer insulating component 54, while also better controlling the overall height of the product.

[0039] Please see Figure 3 and Figure 4In some optional embodiments, the positioning platform 10 includes a support base 11, a first base plate 12, and a second base plate 13. The first base plate 12 is disposed on the support base 11, and the second base plate 13 is disposed on the first base plate 12.

Conversely, the second base plate 13 is connected to a second adjustment component 15, which allows the second base plate 13 to be adjusted and installed at different positions on the first base plate 12, and is mounted on the first base plate 12 through a second adjustment hole 131. Specifically, the positioning platform 10 also includes a plurality of positioning blocks 17 fixed to the second base plate 13. The plurality of positioning blocks 17 and the plurality of positioning components 16 are arranged to form a feeding area 110 for placing the riveting fixture 20. The positioning component 16 includes a positioning cylinder 161 and a limiting structure 162, with the limiting structure 162 mounted on the output end of the positioning cylinder 161. In this embodiment, the support base 11, the first base plate 12, and the second base plate 13 all have through-holes 120 for the limiting structure 162 to move. The positioning cylinder 161 actuates to allow the limiting structure 162 to slide along the through-holes 120 and approach the riveting fixture 20. The end of the limiting structure 162 is bent so that it can extend into the groove 214 and be positioned on the base 21 of the riveting fixture 20.

The pressing mechanism 30 includes a positioning pressure plate 31 that is slidably and vertically mounted above the riveting fixture 20. The vertical movement of the positioning pressure plate 31 is achieved through a guide component 33 and a first guide portion 213 and a second guide portion 313, ensuring better verticality of the movement. The positioning plate 31 presses down to press the inner insulating component 53 and the cover plate component 51 together. A forming hole 311 is provided in the positioning plate 31. The riveting mechanism 40 includes a riveting head 41 located in the forming hole 311. One end of the riveting head 41 away from the riveting fixture 20 protrudes out of the forming hole 311. The riveting mechanism 40 also includes a riveting power assembly 44 and a riveting rod 42. The riveting rod 42 is installed at the output end of the riveting power assembly 44. The riveting power assembly 44 actuates to drive the riveting rod 42 closer to or away from the riveting head 41. The riveting rod 42 approaches the riveting head 41 to push the riveting head 41 to slide along the forming hole 311 and rivet the battery cell cover plate 50 into shape. The dual-axis disconnect riveting device 100 of this utility model has a riveting fixture 20 that can position small-sized battery cell cover plates 50.
