[0036] The utility model proposes a battery pole piece processing device 100, which is used for processing a battery pole piece 200. Please refer to Figures 1 to 7 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.

[0037] 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.

[0038] The driving roller group 10 is connected to the battery electrode 200 for driving the battery electrode 200 to flow through the processing position. The supporting module 20 includes a rolling support plane and a negative pressure component 21 that forms a negative pressure on the rolling support plane. The rolling support plane is arranged below the processing position to rollingly support the battery electrode 200 when the battery electrode 200 flows through the processing position, and to make the battery electrode 200 close to the rolling support plane. The processing component 30 is arranged above the processing position to process the battery electrode 200 when the battery electrode 200 flows through the processing position.

[0039] 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.

[0040] When the battery electrode 200 flows through the processing position, the rolling support plane rolls and supports the battery electrode 200. At the same time, since the negative pressure component 21 forms a negative pressure on the rolling support plane, it provides suction for the rolling support plane. The rolling support plane has suction, so the battery electrode 200 is tightly attached to the rolling support plane.

[0041] It can be understood that since the rolling support plane is used to rollingly support the battery electrode 200, the battery electrode 200 can continue to flow under the driving action of the driving roller group 10. As for the battery electrode processing device 100, 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.

[0042] 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.

[0043] Through the above technical solution, the support module 20 of the present application includes a rolling support plane and a negative pressure component 21 that forms a negative pressure on the rolling support plane. The rolling support plane is arranged below the processing position to roll and support the battery electrode sheet 200 when the battery electrode sheet 200 flows through the processing position, and to make the battery electrode sheet 200 close to the rolling support plane. In this arrangement, the unprocessed battery electrode sheet 200 material strip is driven by the driving roller group 10 to flow through the processing position, and the rolling support plane located below the processing position rolls and supports the battery electrode sheet 200. At the same time, the negative pressure component 21 acts on the rolling support plane, so that the rolling support plane generates negative pressure. The rolling support plane has suction, so the battery electrode sheet 200 is adsorbed and close to the rolling support plane. Since the rolling support plane rolls and supports the battery electrode sheet 200, the battery electrode sheet 200 can continue to flow under the driving action of the driving roller group 10. The negative pressure component 21 located above the processing position The processing component 30 can continuously process the battery electrode 200, thereby ensuring that the battery electrode 200 does not shake during the processing and ensuring the continuity of the processing of the battery electrode 200. Compared with the prior art, the battery electrode processing device 100 provided in the present application can continuously and uninterruptedly complete the processing of a whole roll of battery electrode 200, without the need to start and stop the driving roller that drives the battery electrode 200 material belt to move multiple times. This improves the processing efficiency of the battery electrode processing device 100 on the battery electrode 200, thereby increasing the battery production capacity.

[0044] In some examples, such as Figures 1 to 5 As shown, the support module 20 includes a mounting frame 22 and a rolling support assembly 23. The mounting frame 22 is arranged below the processing position. The mounting frame 22 is provided with a mounting groove 221. The notch of the mounting groove 221 is arranged toward the processing assembly 30. The rolling support assembly 23 includes a rolling support group 231. The rolling support group 231 includes a plurality of rolling support members 232. The plurality of rolling support members 232 are respectively installed in the mounting groove 221 and arranged and distributed along the flow direction of the battery electrode 200, so that each rolling support member 232 is in rolling contact with the battery electrode 200 at the notch of the mounting groove 221 to form a rolling support plane. The negative pressure assembly 21 is installed on the mounting frame 22 and acts on the rolling support plane to use the rolling support plane to form negative pressure.

[0045] There are many types of the rolling support member 232, including but not limited to adsorption rollers 2321, rollers 2322, rollers, etc. There are also many ways to install the rolling support member 232 in the mounting groove 221. In one setting form, the rolling support member 232 is rotatably installed in the mounting groove 221, and the rolling support member 232 can rotate relative to the mounting frame 22 under the drive of the battery pole piece 200. In another setting form, the rolling support member 232 includes a mounting shaft and a rotating shell, the mounting shaft is fixedly installed in the mounting groove 221, and the rotating shell is rotatably installed on the peripheral side of the mounting shaft, and the rotating shell can rotate relative to the mounting shaft under the drive of the battery pole piece 200.

[0046] It can be understood that each rolling support member 232 is in rolling contact with the battery pole piece 200 at the notch of the mounting groove 221, wherein the area where each rolling support member 232 contacts the battery pole piece 200 is linear, and the surface where the contact areas of multiple rolling support members 232 are located is the rolling support surface.

[0047] In this arrangement, when the battery electrode 200 flows through the processing position, a side portion of each rolling support member 232 away from the bottom of the mounting groove 221 rolls in contact with the battery electrode 200 to form a rolling support plane. Driven by the battery electrode 200, the rolling support member 232 rotates relative to the mounting frame 22, thereby reducing the resistance encountered by the battery electrode 200 during the flow process.

[0048] In some examples, such as Figures 1 to 3 As shown, the rolling support member 232 is an adsorption roller 2321, the interior of the adsorption roller 2321 is hollow, and the circumferential side of the adsorption roller 2321 is provided with an adsorption port connected to the inner cavity of the adsorption roller 2321, and the adsorption port is exposed at the groove of the mounting groove 221. The negative pressure component 21 includes an air pump (not shown), and the air pump is connected to one or both ends of the axial direction of the adsorption roller 2321 so as to be connected to the mounting groove 221 through the inner cavity of the adsorption roller 2321 shaft and the adsorption port.

[0049] In this arrangement, the air pump draws air from the inner cavity of the adsorption roller 2321 to drive the flow of air, so that the adsorption port exposed at the notch of the mounting groove 221 can draw air, and thus a negative pressure is formed at the notch of the mounting groove 221. Since the notch of the mounting groove 221 is adjacent to the rolling support plane, the negative pressure is transmitted to the rolling support plane, providing suction for the rolling support plane, and the battery electrode 200 is tightly attached to the rolling support plane due to the suction force.

[0050] In some examples, such as Figure 2As shown, the suction port includes a plurality of suction holes 2323, and the plurality of suction holes 2323 are spaced apart and distributed around the suction roller 2321. The plurality of suction holes 2323 are usually spaced apart and distributed around the suction roller 2321 evenly, so that when the suction roller 2321 rotates relative to the mounting frame 22, there are always suction holes 2323 exposed at the notch of the mounting groove 221, thereby ensuring that sufficient negative pressure is formed on the rolling support plane.

[0051] In some examples, such as Figure 3 As shown, the suction port includes a plurality of suction slits 2324, which are arranged at intervals along the circumference of the suction roller 2321, and the plurality of suction slits 2324 are also arranged to extend along the axial direction of the suction roller 2321. With such an arrangement, when the suction roller 2321 rotates relative to the mounting frame 22, the suction slits 2324 are always exposed at the notch of the mounting groove 221, thereby ensuring that sufficient negative pressure is formed on the rolling support plane. At the same time, compared with the above-mentioned solution in which the suction port includes a plurality of suction holes 2323, the suction slits 2324 extending along the axial direction of the suction roller 2321 can better form negative pressure at the notch of the mounting groove 221.

[0052] In some examples, such as Figures 4 to 7 As shown, the rolling support member 232 is a roller 2322, and multiple rollers 2322 are spaced apart along the flow direction of the battery electrode 200, so that the rolling support assembly 23 forms multiple spaced air slits 233 in the flow direction of the battery electrode 200, and the negative pressure assembly 21 is connected to the mounting groove 221.

[0053] With such a configuration, the negative pressure component 21 can drive the flow of air by sucking air from the mounting groove 221, so that negative pressure is formed in the mounting groove 221. The negative pressure can be transmitted to the rolling support plane through a plurality of air vents 233 arranged at intervals, providing suction for the rolling support plane, and the battery pole piece 200 will be closely attached to the rolling support plane due to the suction. Compared with the above-mentioned scheme in which the air pump is connected to one or both ends of the adsorption roller 2321 in the axial direction, the negative pressure component 21 is connected to the mounting groove 221, and the installation of the rolling support member 232 in this scheme is simpler, thereby improving the assembly efficiency of the battery pole piece processing device 100.

[0054] In some examples, such as Figure 4 and Figure 5 As shown, the negative pressure component 21 includes a base 211 and an air pump. The base 211 is provided with an air groove 212. The side of the mounting frame 22 away from the battery electrode 200 covers the notch of the air groove 212 to form a sealed air chamber 213. The bottom wall of the mounting groove 221 is provided with an air vent 222 connected to the air chamber 213. The air pump is connected to the air chamber 213 and is used to suck the gas in the air chamber 213 to form a negative pressure in the mounting groove 221.

[0055] The number of the air holes 222 can be multiple, and the multiple air holes 222 are evenly spaced and distributed on the lower wall of the mounting groove 221. In this way, the negative pressure component 21 can evenly act on the mounting groove 221 through the base 211, and the mounting groove 221 is isolated by the air chamber 213 to prevent some debris on the battery electrode 200 from affecting the normal operation of the air pump.

[0056] In some examples, the bottom of the base 211 is provided with an exhaust port connected to the air chamber 213, and the air pump is connected to the air chamber 213 through the exhaust port. In this way, the air pump can be arranged outside the base 211 through the exhaust port, and the air pump can be connected to the exhaust hole using an air pipe, which facilitates the installation of the negative pressure component 21.

[0057] In some examples, such as Figure 6 As shown, each roller 2322 at least partially extends out of the mounting slot 221 and rolls in contact with the battery pole piece 200 to support the battery pole piece 200, and the mounting frame 22 is spaced apart from the battery pole piece 200. The specific extension of each roller 2322 from the mounting slot 221 is not specifically limited in the present invention.

[0058] Such an arrangement avoids sliding friction between the battery pole piece 200 and the mounting frame 22 when the battery pole piece 200 flows through the processing position, thereby increasing the resistance to the flow of the battery pole piece 200 .

[0059] In some examples, such as Figure 3 and Figure 7 As shown, the rolling support assembly 23 includes at least two rolling support groups 231 , and the at least two rolling support groups 231 are arranged at intervals along a direction perpendicular to the flow direction of the battery electrode 200 .

[0060] There are many ways to arrange at least two rolling support groups 231 in a direction perpendicular to the flow direction of the battery electrode 200. In one arrangement, Figure 3 As shown, two adjacent rolling support members 232 in two adjacent rolling support groups 231 can be installed in the mounting groove 221 through the same rotating shaft, that is, a rolling support member 232 in one rolling support group 231 and a rolling support member 232 in another rolling support group 231 can be installed in the mounting groove 221 through the same rotating shaft, and the two rolling support members 232 are spaced apart in a direction perpendicular to the flow direction of the battery electrode 200.

[0061] In another setting, such as Figure 7As shown, the mounting frame 22 is provided with at least one mounting beam extending along the flow direction of the battery electrode 200. When the number of the mounting beams is two or more, at least two mounting beams are spaced apart in a direction perpendicular to the flow direction of the battery electrode 200 to divide the notch of the mounting groove 221 into at least two sub-slots. At least two rolling support groups 231 of the rolling support assembly 23 are installed in the mounting groove 221 and are respectively located in the corresponding sub-slots.

[0062] In this way, the processing area of ​​the processing assembly 30 for processing the battery pole piece 200 can be located in the gap between the two rolling support groups 231 to further improve the stability of the battery pole piece 200 during the processing. Of course, in other embodiments, the processing area of ​​the processing assembly 30 for processing the battery pole piece 200 can also be located directly above the rolling support group 231. At the same time, the combination of multiple rolling support groups 231 can enable the battery pole piece processing device 100 to process battery pole pieces 200 with a wider width.

[0063] 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.

[0064] 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.
