Preferably, the telescopic member is a cylinder. When in use, the cylinder contracts to drive the two frame plates 1001 arranged opposite to each other, so that the rollers 101 installed on the frame plates 1001 have a tendency to move toward the battery side wall 310.

The adjustment slot 1002b here can realize the deformation of the shaft hole 1002a, which is convenient for locking or loosening the adjustment shaft 10026 on the inner wall of the shaft hole 1002a, so as to adjust the angle between the fork frame 10024, that is, the rotating shaft of the roller 101 and the battery side wall 310.

[0036] In some embodiments, a limit plate 10023 is provided on the top of the seat plate 10021. The limit plate 10023 is used to limit the extreme position of the fork frame 10024 to prevent it from being over-adjusted.

[0037] Furthermore, a dust suction port 10027 is provided through the bottom of the fork frame 10024, and a brush 10028 is mounted on the fork frame 10024.

When in use, the working end of the brush 10028 can sweep the metal debris on the roller 101 during the rotation of the roller 101 to ensure that there is no metal impurities on the surface of the roller 101, thereby ensuring the rolling quality, and the generated metal debris is removed from the dust suction port 10027 by the negative pressure source.

[0038] In this embodiment, a dust suction connector 10022 is provided on the fork frame 10024. The dust suction connector 10022 is located on the side of the dust suction port 10027 away from the roller 101, and is used to connect to a negative pressure source through a pipeline.

[0039] Furthermore, in order to improve the collection capacity of metal debris, such as Figure 6 and Figure 7 As shown, a windshield 10025 is provided on the fork frame 10024, and the windshield 10025 is located on the side of the dust suction port 10027 close to the roller 101, and extends from the dust suction port 10027 to the roller 101. The windshield 10025 cooperates with the fork frame 10024 structure to achieve the sealing of the area between the roller 101 and the dust suction port 10027, which is conducive to the formation of negative pressure in the area, thereby facilitating the removal effect of metal debris swept by the brush 10028.

[0040] In this embodiment, Figure 4As shown, the clamp 2 includes a substrate 21 and a mechanical pressing claw 22 disposed on the substrate 21. The battery housing 3 is placed on the substrate 21 and is pressed and fixed by the mechanical pressing claw 22.

[0041] In this embodiment, the frame 103 includes a top plate 1031, a middle plate 1032 and a bottom plate 1033 arranged in sequence from top to bottom along the longitudinal direction. The frame plate 1001 is slidably installed on the top plate 1031. The top plate 1031 is slidably connected to the middle plate 1032. The sliding direction of the top plate 1031 relative to the middle plate 1032 is perpendicular to the sliding direction of the frame plate 1001 relative to the top plate 1031.

Here, the frame plate 1001 is slidably connected to the top plate 1031 via a slide rail and a slider structure, and the top plate 1031 is slidably connected to the middle plate 1032 via a slide rail and a slider structure.

[0043] This embodiment also provides a battery processing device, including a feeding mechanism (not shown in the figure), a feeding mechanism (not shown in the figure) and the above-mentioned battery side seam welding seam shaping mechanism, the feeding mechanism is located on the feeding side of the battery side seam welding seam shaping mechanism, and the feeding mechanism is located on the feeding side of the battery side seam welding seam shaping mechanism. The battery processing device can improve the quality of the battery, the processed monomers are convenient to assemble in the battery box, the gap between the monomer batteries is small, which is conducive to improving the energy density of the battery pack.

[0044] The battery side seam welding seam shaping mechanism performs seam shaping based on the aforementioned battery side seam welding seam shaping method.

[0045] like Figure 1-3 and Figure 8 As shown, this embodiment also provides a battery side seam welding seam shaping method, which uses the battery side seam welding seam shaping mechanism to perform weld shaping, including the following steps:

[0046] Step S1: On one of the battery side walls 310 of the battery housing 3, the roller 101 is brought into contact with the protruding structure 35 on the weld, and a pre-tightening force is applied to the roller 101 toward the battery side wall 310 so that the roller 101 has a movement tendency toward the battery side wall 310;

[0047] Step S2: driving the roller 101 to roll along the weld on the battery side wall 310 to within the R angle 33 of the weld end.

[0048] like Figure 2 and Figure 3 As shown, after the roller 101 has a pre-tightening force toward the battery side wall 310, it can roll the protruding structure 35 while the roller 101 rolls along the weld, so as to roll the protruding structure 35 flat, so as to avoid the protruding structure 35 occupying space on the side of the battery shell 3. At the same time, in this embodiment, the roller 101 rolls to the range of the R angle 33. Since the roller 101 has a movement tendency toward the corresponding battery side wall 310, the roller 101 still has the ability to roll the protruding structure 35 flat within the range of the R angle 33, so as to roll the protruding structure 35 within the range of the R angle 33, and the protruding structure 35 at the transition position between the R angle 33 and the battery side wall 310, which can effectively reduce the risk of the protruding structure 35 puncturing the membrane. Specifically, as Figure 3 As shown, the roller 101 has a tendency to move rightward. After the roller 101 moves downward to within the range of the R angle 33, the movement of the roller 101 is a combination of downward and rightward movement. That is, after controlling the roller 101 to move downward, the roller 101 can move along the contour of the R angle 33 to fully roll out the raised structure 35 in the R angle 33 area.

[0049] It should be noted that the R angle 33 area can be partially or completely rolled flat according to actual needs. Figure 3 As shown, in some embodiments, the raised structures 35 in all battery side walls 310 may be rolled first, and then the raised structures 35 in the R-corner 33 region may be rolled separately; or after rolling the raised structures 35 in one of the battery side walls 310 to the R-corner 33, the raised structures 35 in the R-corner 33 region may be directly entered to roll the raised structures 35 in the R-corner 33 region.

[0050] like Figure 3 As shown, the battery in this embodiment is a square shell battery, and the weld between the top cover 32 and the outer shell 31 is located inside the battery side wall 310 and includes a pair of long sides 001 and a pair of short sides 002, and the R angle 33 area connects the adjacent long sides 001 and short sides 002.

[0051] In some embodiments, before step S1, the following steps are also included:

[0052] Step S01 : The roller 101 is brought into contact with the long side 001 or the short side 002 , and the roller 101 is driven to move along the long side 001 or the short side 002 to the R corner 33 close to the end of the long side 001 or the R corner 33 close to the end of the short side 002 .

[0053] The long side 001 and the short side 002 account for the vast majority of the weld, and the pressure consistency of the roller 101 during the rolling process is high. Therefore, the roller 101 is easy to adjust during the rolling of the long side 001 and the short side 002 separately, which is conducive to improving the efficiency of the weld rolling. Then, step S1 and step S2 are performed near the R angle 33 of the long side 001 or the short side 002. Since the battery side wall 310 near the R angle 33 of the long side 001 and the short side 002 has a higher rigidity, the risk of deformation of the battery housing 3 when the preload force is applied is lower. Therefore, when step S01, step S1 and step S2 are performed in sequence, the efficiency of the rolling weld can be improved while ensuring that the structure of the battery housing 3 is not deformed.

[0054] It should be noted that, in step S2, the rolling area of ​​the roller 101 at least covers the boundary points of the rolling area of ​​the roller 101 in step S01.

[0055] like Figure 3 As shown, the junction point between the long side 001 and the R corner 33 is defined as the long side junction point 01, the junction point between the short side 002 and the R corner 33 is defined as the short side junction point 03, and the R corner 33 is divided into two equal parts by the middle point 02. In some embodiments, the following steps are also included after step S2:

[0056] Step S31: When the roller 101 enters the R angle 33 from the long side 001, the starting point of the roller 101 is defined as the long side starting point, and the roller 101 rolls back and forth in the area between the center point 02 and the long side starting point; when the roller 101 enters the R angle 33 from the short side 002, the starting point of the roller 101 is defined as the short side starting point, and the roller 101 rolls back and forth in the area between the center point 02 and the short side starting point.

[0057] In another embodiment, step S2 further includes the following steps:

[0058] Step S00: When the roller 101 enters the R angle 33 from the long side 001, the starting point of the roller 101 is defined as the long side starting point; when the roller 101 enters the R angle 33 from the short side 002, the starting point of the roller 101 is defined as the short side starting point. In the adjacent long side 001 and short side 002, the roller 101 reciprocates in the area between the short side starting point and the long side starting point; or the roller 101 rolls at least once in one direction from the short side starting point to the long side starting point; or the roller 101 rolls at least once in one direction from the long side starting point to the short side starting point. Reciprocating rolling or at least one rolling ensures the welding seam rolling shaping effect.

[0059] like Figure 2As shown, the angle between the rotating shaft of the roller 101 and the battery side wall 310 is α, 0°≤α≤15°. The specific angle between the rotating shaft of the roller 101 and the battery side wall 310 is adjusted according to actual needs to ensure the rolling effect.

[0060] In some embodiments, during the unidirectional movement of the roller 101 from the battery side wall 310 into the R angle 33 area, the preload force gradually increases. Figure 3 As shown, when the roller 101 enters the R angle 33 area from the long side 001, the original preload force may be insufficient for the roller 101 to roll to the right due to the effect of the R angle 33 structure. Therefore, when entering the R angle 33 area, the force value is continuously increased in the direction of the original preload force to ensure the rolling shaping effect.

[0061] In this embodiment, the rolling speed of the roller 101 gradually decreases as the roller 101 moves from the battery side wall 310 into the R angle 33 area. Due to the influence of the R angle 33 structure, the roller 101 speed is reduced to prevent slipping and ensure the rolling effect.

[0062] In this embodiment, there are two rollers 101, and the two rollers 101 correspond to the two oppositely disposed battery side walls 310 one by one. In the extension direction of the weld on the battery side wall 310, the two rollers 101 move synchronously; when the rollers 101 enter the R angle 33 range from the battery side wall 310, the distance between the two rollers 101 gradually decreases. Specifically, a group of oppositely disposed long sides 001 or short sides 002 are rolled at the same time, which is conducive to improving the rolling efficiency. At the same time, the pre-tightening forces of the two oppositely disposed rollers 101 are in opposite directions, thereby ensuring the stability of the battery housing 3 clamping.

[0063] It should be noted that the roller 101 and the battery housing 3 are in relative motion, that is, the battery housing 3 can be fixed to drive the roller 101 to move relative to the battery housing 3; the roller 101 can also be fixed to drive the battery housing 3 to move relative to the roller 101; or both the battery housing 3 and the roller 101 can move.

[0064] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
