Description

Technical Field

[0001] The utility model relates to the technical field of battery cell production equipment, in particular to a two-sealing automatic edge-smoothing and feeding device. Background Art

[0002] With the rapid development of the new energy industry in recent years, more and more energy storage batteries have been produced. As the core of new energy batteries, the battery cell needs to go through multiple processes in its production process, including coating, rolling, sealing, liquid injection, formation, secondary sealing, aging, etc. Each process plays an important role in the quality of the battery cell.

[0003] The second sealing process refers to extracting the gas inside the battery cell and performing secondary sealing and molding. It requires puncturing the airbag of the battery cell, evacuating the inside of the airbag, sealing the edges, cutting off the excess airbag, and finally folding the edges. When the battery cell is transported after the edge sealing is completed, the airbag is prone to folding on its own. If the folded part is not smoothed out, the airbag at the folded part often misses cutting when the battery cell is trimming, resulting in insufficient cutting and leaving excess airbags, which causes poor trimming or burring, and then leads to poor subsequent folding of the battery cell, affecting product quality. Nowadays, workers often need to manually smooth the edges before trimming, which not only consumes a lot of manpower costs, but also has low production efficiency. Utility Model Content

[0024] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0025] Reference Figure 1-2 , Figure 1 This is a schematic diagram of the structure of the second-seal automatic edge-smoothing and feeding device in the embodiment. Figure 2 for Figure 1In the enlarged view of the middle A part, the double-sealed automatic edge-smoothing feeding device in this embodiment includes a feeding component 1 and an edge-smoothing component 2. The feeding component 1 includes a track member 11 and a feeding component 12. The feeding component 12 is movably arranged on the track member 11. The edge-smoothing component 2 includes an edge-smoothing platform member 21 and an edge-smoothing member 22. The edge-smoothing platform member 21 is arranged adjacent to the track member 11. The edge-smoothing member 22 has an edge-smoothing surface 221. There is an angle between the edge-smoothing surface 221 and the surface of the edge-smoothing platform member 21. When the feeding component 12 feeds the battery cell 100 to the edge-smoothing platform member 21, the side edge of the battery cell 100 slides along the edge-smoothing surface 221, and the edge-smoothing surface 221 performs edge-smoothing on the side edge of the battery cell 100.

[0026] The second-sealed automatic edge-smoothing and feeding device in this embodiment is used for the production of lithium battery cells, specifically, the edge of the cell is smoothed synchronously when the cell is fed in the second-sealing process. Since the edge-smoothing piece 22 is provided with an edge-smoothing surface 221, when the cell is second-sealed and fed, the side of the cell slides along the edge-smoothing surface 221, and the edge-smoothing surface 221 applies pressure to the airbag on the side of the cell, so that the airbag on the side is smoothed and pressed against the clip in the middle of the cell, and the airbag is folded as a whole, and the fine fold formed by the previous self-folding is smoothed at the same time, avoiding the poor folding caused by the fine folding generated by itself, improving product quality, saving the time and labor cost of manual edge-smoothing, improving production efficiency, and saving production costs.

[0027] Re-reference Figure 1-2 Preferably, there are two feeding pieces 12, and the two feeding pieces 12 are movably arranged on the track piece 11, one of which feeds the battery cell 100 to the trimming platform piece 21 for trimming, and the other feeding piece 12 transfers the trimmed battery cell 100. In specific applications, the track piece 11 includes a track frame, a rotating screw, a movable nut and a driving motor. The rotating screw is rotatably arranged in the track frame and connected to the driving end of the driving motor. The movable nut is arranged on the feeding piece 12. Through the cooperation of the rotating screw and the movable nut, the feeding piece 12 can move back and forth on the track piece 11. Of course, the track piece 11 can also drive the feeding piece 12 to move by the cooperation of the slide rail and the slider, which is not limited here. It is understandable that one loading part 12 is responsible for transferring the battery cell after the previous process to the edge trimming platform part 21 for edge trimming. After the edge trimming is completed, the other loading part 12 transfers the battery cell after the edge trimming to the next process. It should be noted that the two loading parts 12 are in a synchronous motion state, that is, when one of the loading parts 12 absorbs the battery cell from the previous process, the other loading part 12 is located at the edge trimming platform part 21 to absorb the battery cell. When one of the loading parts 12 is trimming the battery cell at the edge trimming platform part 21, the other loading part 12 is located at the next process to transfer the battery cell to the next process. In this way, the loading and trimming processes of the battery cell are closely connected, which improves production continuity and production efficiency.

[0028] Re-reference Figure 1-2Preferably, the loading member 12 includes a lifting part 121 and a suction part 122. The lifting part 121 is movably arranged on the track member 11. The suction part 122 is connected to the driving end of the lifting part 121. The suction end of the suction part 122 faces the battery cell 100 on the edge-smoothing platform member 21. In specific applications, the suction part 122 includes a suction carrier 1221 and two vacuum suction heads 1222. The suction carrier 1221 is connected to the driving end of the lifting part 121. The two vacuum suction heads 1222 are respectively arranged on the suction carrier 1221. The suction ends of the vacuum suction heads 1222 face the battery cell 100 on the edge-smoothing platform member 21. Through the setting of the vacuum suction head 1222, compared with the method of grabbing the battery cell for transfer by the manipulator, the vacuum suction head 1222 adsorbs the battery cell less likely to cause damage to the battery cell, thereby improving product quality. At the same time, one adsorption part 122 is provided with two vacuum suction heads 1222, so that the adsorption force is more uniform when adsorbing the battery cell, further avoiding damage to the battery cell during transportation, and also ensuring that the battery cell is parallel to the surface of the edge straightening platform part 21 during transportation, thereby improving the subsequent edge straightening effect of the battery cell. The edge straightening and smoothing described in this application are the same concept, both referring to folding and smoothing the airbags on the side of the battery cell. Specifically, the lifting part 121 is a lifting cylinder.

[0029] Re-reference Figure 1-2 , preferably, the edge-smoothing piece 22 and the edge-smoothing platform piece 21 can move relative to each other. It can be understood that the edge-smoothing piece 22 and the edge-smoothing platform piece 21 are not in a fixed connection state. When the edge-smoothing piece 22 moves relative to the edge-smoothing platform piece 21, the position of the edge-smoothing surface 221 on the edge-smoothing platform piece 21 also changes accordingly. The edge-smoothing platform piece 21 plays a role in supporting the battery cell when the battery cell is edge-smoothing. By adjusting the position of the edge-smoothing piece 22, the position and size of the area of ​​the edge-smoothing platform piece 21 used to support the battery cell are changed. In this way, the position of the edge-smoothing piece 22 can be adjusted according to the size and specification of the battery cell to be edge-smoothed, so as to adapt to battery cells of different sizes and specifications, thereby widening the adaptation range.

[0030] Re-reference Figure 1-2Preferably, the edge-smoothing platform component 21 includes an edge-smoothing platform 211 and two platform frames 212. The two ends of the edge-smoothing platform 211 are respectively arranged on the two platform frames 212, and an angle is formed between the edge-smoothing surface 221 and the surface of the edge-smoothing platform 211. In specific applications, the two platform frames 212 are arranged at intervals, and the edge-smoothing platform 211 is arranged on the platform frames 212, that is, the platform frames 212 are used to fix the edge-smoothing platform 211. In other words, by adjusting the spacing between the two platform frames 212 and replacing the edge-smoothing platforms 211 of different sizes, it is possible to adapt to cells of different sizes and specifications, thereby widening the adaptation range. Furthermore, the edge-smoothing component 22 also includes a shaping block 222. The two ends of the shaping block 222 are respectively detachably connected to the two platform frames 212, and the edge-smoothing surface 221 is formed on the surface of the shaping block 222. It can be understood that the shaping block 222 in this embodiment is an independent component, which is arranged on the surface of the trimming platform 211 and is detachably connected to the platform frame 212. When the loading part 12 transfers the battery cell to the top of the shaping block 222, the lifting part 121 drives the battery cell to descend and makes the battery cell slide along the trimming surface 221. The clip in the middle of the battery cell is always in close contact with the trimming surface 221, that is, the airbag on the side of the battery cell is folded relative to the clip by the trimming surface 221. Since the clip is always in close contact with the trimming surface 221, the spontaneous folding of the airbag generated in the previous production and transportation process is also synchronously smoothed, thereby avoiding the subsequent trimming and folding defects and improving product quality. Furthermore, the angle between the trimming surface 221 and the trimming platform 211 is 45°. The size of the angle between the edge straightening surface 221 and the edge straightening platform 211 determines the pressure exerted by the edge straightening surface 221 on the battery cell when straightening the battery cell. When the angle is less than 45°, insufficient pressure often causes the spontaneous folding area to fail to be fully flattened, while too large an angle may easily cause excessive pressure between the battery cell and the shaping block 222, thereby causing damage to the battery cell. Preferably, the edge straightening effect is better when the angle is 45°.

[0031] Re-reference Figure 1-2 Preferably, the platform frame 212 is provided with a plurality of positioning holes 2121 in a direction perpendicular to the connection line of the two platform frames 212, and mounting holes 2221 are respectively provided at the two ends of the shaping block 222 at positions corresponding to the positioning holes 2121, and the shaping block 222 can be detachably mounted on the platform frame 212 through the cooperation of the positioning holes 2121 and the mounting holes 2221. In specific applications, by adjusting the spacing between the two platform frames 212 and the size of the trimming platform 211, the battery cells of different lengths can be adapted, and by the cooperation of the positioning holes 2121 and the mounting holes 2221, the position of the shaping block 222 on the trimming platform 211 can be adjusted, so as to adapt to battery cells of different widths, thereby broadening the adaptation range of this embodiment.

[0032] Re-reference Figure 1-2Preferably, the two-sealed automatic edge-smoothing feeding device also includes a scanning component 3, and the scanning end of the scanning component 3 faces the battery cell 100 on the edge-smoothing platform 21. In specific applications, when one of the feeding components 12 slides the battery cell along the edge-smoothing surface 221 to complete the edge-smoothing, the battery cell is immediately placed on the edge-smoothing platform 211, and the scanning component 3 scans the information code on the battery cell and transmits the information to the battery cell production system, so that the entire process of the battery cell production process is controlled. Specifically, the scanning component 3 is a barcode scanning gun, and the edge-smoothing platform 211 is made of a transparent material. In this way, a light source can be set at the bottom of the edge-smoothing platform 211 to illuminate the battery cell on the edge-smoothing platform 211, so that the scanning component 3 can better scan the battery cell. Furthermore, the edge-smoothing platform 211 is made of a transparent acrylic material, and the properties of acrylic are stable and tough. Compared with materials such as glass plates, it is not easy to form a flash to damage the battery cell.

[0033] To summarize, since the whole edge piece is provided with a whole edge surface, when the battery cell is subjected to the second sealing and loading, the side of the battery cell slides along the whole edge surface, and the whole edge surface applies pressure to the airbag on the side of the battery cell, so that the airbag on the side is flattened and pressed against the spring clip in the middle of the battery cell, and while folding the airbag as a whole, the slight fold formed by the previous self-folding is also flattened, avoiding poor folding caused by slight folding generated by itself, improving product quality, saving time and labor cost of manual smoothing, improving production efficiency, and saving production cost.
