[0034] The utility model provides a battery pole piece processing device 100, which is used for processing a battery pole piece 200. Please refer to Figures 1 to 4 In the embodiment of the utility model, the battery pole piece processing device 100 is provided with a processing position, and the battery pole piece processing device 100 includes a driving roller group 10, a supporting module 20 and a processing assembly 30. It can be understood that the processing position refers to a certain spatial position of the battery pole piece processing device 100 for processing the battery pole piece 200, and does not specifically refer to the surface or inner cavity of a certain component.

[0035] It should be noted that the battery electrode 200 is in the shape of a long strip before being cut and processed. The battery electrode 200 is usually rolled into a roll for storage. Therefore, the battery electrode processing device 100 proposed in the utility model can be used in combination with a material strip unwinding device and a material strip winding device, that is, the material strip unwinding device is used to unwind the battery electrode 200 roll to provide raw materials for processing by the battery electrode processing device 100. After the processing of the battery electrode 200 is completed, the material strip winding device winds up the processed battery electrode 200.

[0036] The driving roller assembly 10 is connected to the battery electrode 200 in a transmission manner to drive the battery electrode 200 to flow through the processing position. The support module 20 includes a mobile support module 21 and a negative pressure assembly movably arranged below the processing position. The mobile support module 21 has a support plane 2111. The negative pressure assembly acts on the support plane 2111 so that the support plane 2111 forms a negative pressure, so that when the battery electrode 200 flows through the processing position, the battery electrode 200 is close to the support plane 2111, and the moving speed of the mobile support module 21 close to the battery electrode 200 is consistent with the moving speed of the battery electrode 200. The processing assembly 30 (not shown) is arranged above the processing position to process the battery electrode 200 when the battery electrode 200 flows through the processing position.

[0037] In some embodiments, the driving roller assembly 10 includes two driving rollers, which are respectively located upstream and downstream of the support module 20 in the flow direction of the battery pole piece 200. The circumferential sides of the two driving rollers are in contact with the surface of the battery pole piece 200 to drive the battery pole piece 200 to flow in a predetermined direction by friction. The driving roller located upstream of the support module 20 in the flow direction of the battery pole piece 200 drives the battery pole piece 200 to flow to the processing position. After the battery pole piece 200 is processed at the processing position, the driving roller located downstream of the support module 20 in the flow direction of the battery pole piece 200 drives the battery pole piece 200 to flow out of the battery pole piece processing device 100. The two driving rollers are at the same height in the vertical direction so that the battery pole piece 200 between the two driving rollers is parallel to the horizontal plane.

[0038] When the battery electrode 200 flows through the processing position, the negative pressure component acts on the supporting plane 2111, so that the supporting plane 2111 forms a negative pressure, providing suction for the supporting plane 2111. At the same time, since the mobile support module 21 with the supporting plane 2111 is movably arranged below the processing position, the supporting plane 2111 can not only absorb the battery electrode 200 and make the battery electrode 200 close to the supporting plane 2111, but also make the mobile support module 21 close to the battery electrode 200 move relatively, and can make the moving speed of the mobile support module 21 close to the battery electrode 200 consistent with the moving speed of the battery electrode 200. That is, under the driving action of the driving roller group 10, the battery electrode 200 can continue to flow, and the mobile support module 21 with the support plane 2111 moves at the same moving speed, so that the battery electrode 200 and the support plane 2111 to which the battery electrode 200 is tightly attached are relatively still. As far as the battery electrode processing device 100 is concerned, the driving roller group 10 can continuously drive the battery electrode 200 to flow, and the processing component 30 can also continuously process the battery electrode 200 tightly attached to the support plane 2111.

[0039] The processing assembly 30 includes but is not limited to a laser, an air knife, and a magnetic rod. When the processing assembly 30 includes a laser, the battery pole piece processing device 100 can be used for marking and cleaning the battery pole piece 200, and when the processing assembly 30 includes an air knife, the battery pole piece processing device 100 can be used for cleaning the battery pole piece 200.

[0040] In the present application, through the above technical scheme, the unprocessed battery pole piece 200 material strip is driven by the driving roller group 10 to flow through the processing position, and the movable support module 21 located below the processing position has a supporting plane 2111. Under the action of the negative pressure component, the supporting plane 2111 forms a negative pressure, and the supporting plane 2111 has suction, so that the battery pole piece 200 is adsorbed and pressed against the supporting plane 2111. At the same time, since the movable support module 21 is movably arranged below the processing position, the movable support module 21 pressed against the battery pole piece 200 can also be relatively moved, and the moving speed of the movable support module 21 pressed against the battery pole piece 200 is kept consistent with the moving speed of the battery pole piece 200. During the processing of the battery pole piece processing device 100, the driving action of the driving roller group 10 drives the battery pole piece 200 to move relative to the moving speed of the battery pole piece 200. The battery electrode sheet 200 is constantly flowing, and the mobile support module 21 with the support plane 2111 moves at the same moving speed, so that the battery electrode sheet 200 and the support plane 2111 to which the battery electrode sheet 200 is closely attached are relatively still, thereby ensuring that the battery electrode sheet 200 does not shake during the processing, and ensuring the continuity of the processing of the battery electrode sheet 200, and reducing the friction between the battery electrode sheet 200 and the support plane 2111, thereby ensuring the quality of the battery electrode sheet 200. Compared with the prior art, the battery electrode sheet processing device 100 provided in the present application can continuously and uninterruptedly complete the processing of a whole roll of battery electrode sheets 200, without the need to start and stop the driving roller that drives the battery electrode sheet 200 material belt to move multiple times, thereby improving the processing efficiency of the battery electrode sheet processing device 100 on the battery electrode sheet 200, thereby improving the battery production capacity.

[0041] In some examples, such as Figures 1 to 4 As shown, the support module 20 also includes a mounting frame 22, and the mobile support module 21 includes a support plate 211 having a support plane 2111 and a driving member 212, and the support plate 211 is movably arranged on the mounting frame 22 through the driving member 212 to move relative to the mounting frame 22 under the drive of the driving member 212.

[0042] The support plate 211 is movably arranged on the mounting frame 22 by the driving member 212, and there are multiple settings. In one setting, the driving member 212 can drive the support plate 211 to reciprocate in a direction parallel to the flow direction of the battery electrode 200 and to lift and lower in a direction perpendicular to the flow direction of the battery electrode 200. Specifically, the battery electrode 200 is close to the support plate 211, and the driving member 212 drives the support plate 211 to move in a direction parallel to the flow direction of the battery electrode 200. During this process, the processing assembly 30 processes the battery electrode 200. After the processing of the battery electrode 200 is completed, the driving member 212 drives the support plate 211 to move downward in a direction perpendicular to the flow direction of the battery electrode 200, and then the driving member 212 drives the support plate 211 to move back in a direction parallel to the flow direction of the battery electrode 200, and then the driving member 212 drives the support plate 211 to move upward in a direction perpendicular to the flow direction of the battery electrode 200 to return to the initial position, and the support plane 2111 adsorbs the next processing area of ​​the battery electrode 200.

[0043] In another configuration, a circular track is provided on the mounting frame 22 , and the driving member 212 drives the supporting plate 211 to move along the circular track, so that the supporting plane 2111 cyclically adsorbs and supports the battery pole piece 200 .

[0044] With such a configuration, the support plate 211 can move relative to the mounting frame 22 driven by the driving member 212, so that during the processing of the battery electrode 200, the supporting plane 2111 on the support plate 211 can absorb and support the battery electrode 200 to ensure that the battery electrode 200 does not shake. After the processing of this area of ​​the battery electrode 200 is completed, the driving member 212 can drive the support plate 211 to move again, so that the supporting plane 2111 can absorb and support the next processing area of ​​the battery electrode 200, thereby further ensuring the continuity of the processing of the battery electrode 200.

[0045] In some examples, such as Figures 1 to 4 As shown, the mounting frame 22 is provided with a first annular track 221, and the first annular track 221 has a support section parallel to the flow direction of the battery electrode 200, and the support plate 211 is movably mounted on the first annular track 221 through a driving member 212 to drive the support plate 211 to move along the first annular track 221; wherein, when the support plate 211 moves along the support section driven by the driving member 212, the battery electrode 200 is closely attached to the support plane 2111, and through the drive of the driving member 212, the moving speed of the support plate 211 closely attached to the battery electrode 200 is kept consistent with the moving speed of the battery electrode 200.

[0046] The driving member 212 includes but is not limited to a movable platform, a synchronous chain, a synchronous belt, etc. When the driving member 212 includes a movable platform, the movable platform can drive the support plate 211 to move along the first circular track 221, and the speed of the support plate 211 in different areas of the first circular track 221 can be arbitrarily adjusted according to the power of the movable platform itself.

[0047] In this arrangement, when the support plate 211 moves along the support section driven by the driving member 212, the support plane 2111 can absorb and support the battery electrode 200 to ensure the processing quality of the battery electrode 200 by the processing assembly 30. When the driving member 212 drives the support member to leave the support section, the driving member 212 can quickly return to the initial position of the support section along the first circular track 221, so that the support plane 2111 can absorb and support the next processing area of ​​the battery electrode 200.

[0048] In some examples, such as Figures 2 to 5 As shown, the first annular track 221 is a magnetic levitation track, and the driving member 212 includes two clamping plates 2121 and two magnetic levitation movers 2122 spaced apart along the length direction of the support plate 211. One end of the two clamping plates 2121 is fixedly connected to the middle part of the support plate 211 in the length direction, and a clamping groove is formed between the two clamping plates 2121. The two magnetic levitation movers 2122 are respectively installed on the corresponding clamping plates 2121. Part of the first annular track 221 is accommodated in the clamping groove and is located between the two magnetic levitation movers 2122.

[0049] In some embodiments, the two magnetic suspension movers 2122 can be installed on the inner side of the two clamping plates 2121, that is, the groove wall of the clamping groove. In other embodiments, the two magnetic suspension movers 2122 can be installed on the outer side of the two clamping plates 2121, that is, outside the clamping groove.

[0050] With such arrangement, when the driving member 212 drives the support plate 211 to move along the magnetic levitation track, the magnetic levitation mover 2122 is spaced apart from the magnetic levitation track, which can reduce the resistance of the driving member 212 moving along the magnetic levitation track, thereby improving the movement efficiency of the driving member 212 and improving the energy utilization rate.

[0051] In some embodiments, the driving member 212 further includes a positioning sensor 214 , which is mounted on one of the clamping plates 2121 . The positioning sensor 214 can detect a trigger mounted on the mounting frame 22 to determine the relative position information between the driving member 212 and the first annular track 221 .

[0052] In some examples, such as Figure 2As shown, the support module 20 includes a plurality of mobile support modules 21, and the plurality of mobile support modules 21 are spaced apart and distributed on the first annular track 221. In this way, the number of mobile support modules 21 can be set according to the intervals between the processing areas required for the battery pole piece 200, thereby ensuring the continuity of the processing of the battery pole piece 200 and improving the utilization rate of the support plane 2111, and the moving speed of each mobile support module 21 can be kept consistent with the moving speed of the battery pole piece 200.

[0053] In other embodiments, when the number of mobile support modules 21 is small, the number of mobile support modules 21 cannot meet the spacing between the processing areas required for the battery pole piece 200. After completing the processing in the processing area of ​​the battery pole piece 200 close to the supporting plane 2111, the mobile support module 21 can accelerate back to the initial position of the support section through the first circular track 221, and then immediately decelerate to the same flow speed as the battery pole piece 200.

[0054] In some examples, such as Figures 2 to 4 As shown, the mounting frame 22 is provided with two second annular rails 222, and the two second annular rails 222 are respectively located on both sides of the first annular rail 221, and the mobile support module 21 also includes two connecting components 213, and the two connecting components 213 are respectively installed at both ends of the support plate 211 in the length direction, and the two connecting components 213 are respectively slidably connected with the corresponding second annular rails 222.

[0055] It should be noted that the two second annular tracks 222 are both adapted to the first annular track 221 , that is, the moving path of the driving member 212 on the first annular track 221 is similar to the moving path of the connecting component 213 on the second annular track 222 .

[0056] With such arrangement, when the two connecting components 213 slide respectively with the corresponding second circular track 222, the driving member 212 can smoothly drive the support plate 211 to move along the first circular track 221, so that the supporting plane 2111 on the support plate 211 is stable, so that the battery pole piece 200 can be stably adsorbed and supported, thereby improving the efficiency of the processing component 30 in processing the battery pole piece 200.

[0057] In some examples, such as Figure 3 , Figure 4 and Figure 6 As shown, each connecting component 213 includes a connecting seat 2131 and two guide wheel groups 2132. The connecting seat 2131 is installed on the support plate 211. The two guide wheel groups 2132 are rotatably installed on the connecting seat 2131 and are respectively located on the inner and outer sides of the second annular track 222. The two guide wheel groups 2132 are also in rolling contact with the inner and outer sides of the second annular track 222 respectively.

[0058] With such arrangement, the connection component 213 can clamp the second annular track 222 through the two guide wheel groups 2132 to prevent the guide wheels on the guide wheel groups 2132 from detaching from the second annular track 222 , thereby ensuring the reliability of the sliding connection between the connection component 213 and the second annular track 222 .

[0059] In some examples, such as Figure 6 As shown, the guide wheels of the two guide wheel groups 2132 are both recessed with guide grooves 2133 , and the inner side and the outer side of the second annular track 222 are both provided with protrusions 2221 that cooperate with the guide grooves 2133 .

[0060] Such a configuration is intended to further ensure the reliability of the sliding connection between the connecting assembly 213 and the second annular track 222 . The protrusion 2221 on the second annular track 222 cooperates with the guide groove 2133 to limit the guide wheel assembly 2132 from being separated from the second annular track 222 .

[0061] In some examples, the support plate 211 is provided with an air duct, one end of which is exposed on the support plane 2111, and the other end of which is connected to the negative pressure component. In this way, the negative pressure component can draw air through the air duct, thereby forming a negative pressure on the support plane 2111 to optimize the layout of the negative pressure component. In combination with the content of the above-mentioned mobile support module 21, in some embodiments, each support plate 211 can be equipped with an independent negative pressure component, or multiple support plates 211 can be connected through air pipes to centrally connect negative pressure components.

[0062] In some examples, such as Figure 1 As shown, the processing assembly 30 includes a laser generating device, and the laser head of the laser generating device is arranged directly opposite to the processing position. In this way, the battery pole piece processing device 100 can perform laser scoring, laser holes, laser marking, laser cleaning and other processing on the battery pole piece 200.

[0063] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
