[0031] With the rapid development of the new energy industry, battery technology is also constantly evolving. The electrode sheet is one of the main components of the battery, and the slicing efficiency of the electrode sheet affects the preparation efficiency of the battery. In the prior art, the electrode sheet cutting system usually uses an electrode roll to feed the strip into a metal tool for cutting, and after the electrode sheet is made, it is transported to the electrode sheet handling station 95 via a belt. However, the slicing efficiency of the electrode sheet cutting system in the prior art is relatively low.

[0032] At the same time, the assembly accuracy of this electrode sheet cutting system is insufficient, and the width of the electrode sheet is prone to inconsistency, affecting the processing quality.

[0033] Based on this, refer to Figure 1 , Figure 1 FIG. 16 is one of the structural schematic diagrams of an electrode sheet cutting system provided by an embodiment of the present application. An embodiment of the present application provides an electrode sheet cutting system 10, which includes a plurality of movers 20, a conveying device 30, and a laser cutting device 40.

[0034] Specifically, refer to Figure 2 , Figure 2 is Figure 1 the enlarged schematic view of part A in FIG. 16. The mover 20 has a first fixing surface 21, and the first fixing surface 21 is used to fix the strip 50. The strip 50 is used to be cut into electrode sheets 60. In this way, by using a plurality of movers 20 to fix the strip 50, multiple strips 50 with the width of the electrode sheet 60 can be pulled out at one time. For the strip 50 with the same width, there is no need for frequent acceleration and deceleration, and most of the feeding process can be in a high-speed movement state, thereby improving the strip supply efficiency of the electrode sheet cutting system 10.

[0035] Meanwhile, transporting the strip 50 through multiple movers 20 can achieve an efficient circulation of the strip, improve the supply efficiency of the strip 50, and thus enable high-speed slicing and improve the slicing efficiency. Arranging multiple movers 20 allows multiple processing operations to be carried out simultaneously, enabling the processing tasks to be completed more quickly and improving the production efficiency.

[0036] Multiple movers 20 are connected to the conveying device 30 and arranged along the conveying direction of the conveying device 30. The conveying device 30 is configured to convey the multiple movers 20 to the cutting station 43 at least along a first direction. Figure 1 The direction F1 in is the conveying direction of the conveying device 30.

[0037] In this way, the automatic conveyance of the multiple movers 20 to the cutting station 43 by the conveying device 30 can reduce manual intervention and labor costs, and improve the automation level of the production line. Additionally, the conveying device 30 can precisely control the position and speed of the multiple movers 20 to ensure their accurate arrival at the cutting station 43, improving the cutting accuracy and consistency.

[0038] The laser cutting device 40 has multiple light-emitting ports 41, which are arranged along the first direction. When the multiple movers 20 are located at the cutting station 43, the first fixing surfaces 21 of the multiple movers 20 face the same direction.

[0039] In this way, the strip 50 transported on the multiple movers 20 can be cut through the multiple light-emitting ports 41, improving the slicing efficiency.

[0040] Among them, there is a gap between two adjacent first fixing surfaces 21, and the light-emitting ports 41 face the first fixing surfaces 21 of the multiple movers 20. In this way, the laser cutting device 40 can perform ear die-cutting on the electrode tab 60.

[0041] In some other embodiments, the light-emitting ports 41 face the gaps between two adjacent first fixing surfaces 21. In this way, the laser cutting device 40 can perform electrode tab cutting on the strip 50.

[0042] It should be noted that the multiple light-emitting ports 41 of the laser cutting device 40 can face the first fixing surfaces 21 of the multiple movers 20, or face the gaps between two adjacent first fixing surfaces 21, or face the first fixing surfaces 21 of the multiple movers 20 while also facing the gaps between two adjacent first fixing surfaces 21. This application does not limit this, and it is specifically set according to the actual needs.

[0043] Exemplarily, the multiple light-emitting ports 41 of the laser cutting device 40 face the first fixing surfaces 21 of the multiple movers 20 while also facing the gaps between two adjacent first fixing surfaces 21. In this way, two processing processes, namely ear die-cutting and electrode tab cutting, can be completed simultaneously, improving the processing efficiency.

[0044] In some embodiments, when multiple movers 20 are located at the cutting station 43, the multiple light-emitting ports 41 are respectively opposite to the gaps of the multiple movers 20.

[0045] In this way, by making the multiple light-emitting ports 41 opposite to the gaps of the multiple movers 20, the multiple movers 20 can be cut simultaneously, thereby improving the production efficiency.

[0046] It should be noted that the multiple light-emitting ports 41 can respectively correspond one-to-one to the gaps of the multiple movers 20, or multiple light-emitting ports 41 can correspond to the gap of one adjacent mover 20. This application does not limit this, and it is specifically set according to the actual needs.

[0047] Exemplarily, the multiple light-emitting ports 41 can respectively correspond one-to-one to the gaps of the multiple movers 20. In this way, by adjusting the positions and parameters of each light-emitting port 41, precise cutting of the tape 50 can be achieved, and the cutting accuracy can be improved.

[0048] In some embodiments, continue to refer to Figure 1 , the laser cutting device 40 includes at least one laser generator 42, and the laser generator 42 includes multiple light-emitting ports 41.

[0049] The laser cutting technology has a higher cutting speed and higher production efficiency compared with traditional cutting methods. Using the laser generator 42 can further improve the cutting efficiency.

[0050] It should be noted that the number of laser generators 42 can be one or multiple. This application does not limit this, and it is specifically set according to the actual needs.

[0051] Exemplarily, continue to refer to Figure 1 , the number of laser generators 42 is two. In this way, setting two laser generators 42 can allow for more settings and is more flexible in processing the tape 50. For example, pole piece 60 cutting can be set at the first laser generator 42, and tab die-cutting can be set at the second laser generator 42.

[0052] In some embodiments, continue to refer to Figure 2 , the mover 20 includes a first adsorption structure 22, and the first adsorption surface 23 of the first adsorption structure 22 forms a first fixing surface 21.

[0053] In this way, the multiple movers 20 adsorb the tape 50 through the first adsorption surface 23 of the adsorption structure 22, and each part of the tape 50 can be tightly fixed on the mover 20, enabling high-efficiency traction of the tape 50, ensuring the flatness of the tape 50, facilitating high-speed slicing, ensuring the width of the pole piece 60, and ensuring the slicing quality of the pole piece 60.

[0054] Meanwhile, after the strip 50 is adsorbed on the mover 20 and pulled out, other processing methods such as slicing are performed, and the relative positions of the pole piece 60 and the mover 20 will no longer change, eliminating the need for deviation correction, which is beneficial to improving production efficiency.

[0055] It should be noted that the first adsorption structure 22 can be vacuum adsorption, electro-adsorption, magnetic adsorption, chemical adsorption, etc. This application does not limit this, and it is specifically set according to the actual situation.

[0056] Exemplarily, the first adsorption structure 22 can be electrostatic adsorption. This can make the structure of the adsorption structure 22 relatively simple and convenient for processing.

[0057] In some embodiments, the pole piece cutting system 10 further includes a first pressing roller 70. A gap for the strip 50 to pass through is formed between the first pressing roller 70 and the first fixing surface 21 of the mover 20. With such a setting, by setting the first pressing roller 70 and controlling the gap between the first pressing roller 70 and the first fixing surface 21, it is beneficial to make the strip 50 close to the first fixing surface 21, so as to facilitate the first fixing surface 21 to fix the strip 50 and drive the strip 50 to move.

[0058] In some embodiments, the pole piece cutting system 10 further includes a second pressing roller 80. The second pressing roller 80 is relatively fixed to the external carrier, and the strip 50 is conveyed to the first pressing roller 70 through the second pressing roller 80.

[0059] In some embodiments, a pre-adsorption area for the strip 50 can also be provided between the first pressing roller 70 and the cutting station 43. In this way, the strip 50 can be more firmly adsorbed in the pre-adsorption area, preventing the strip 50 from being misaligned.

[0060] In some embodiments, continue to refer to Figure 1 and in combination with Figure 2 , the conveying device 30 is further used to convey a plurality of movers 20 to the handling station 95. The pole piece cutting system 10 further includes a handling device 90. The handling device 90 has a plurality of second fixing surfaces 92. When the plurality of movers 20 are located at the handling station 95, the plurality of second fixing surfaces 92 face the first fixing surfaces 21 of the plurality of movers 20 respectively.

[0061] In this way, through the conveying device 30, the mover 20 can transport the pole piece 60 to the handling station 95. The handling device 90 handles the pole piece 60 by setting the second fixing surface 92.

[0062] It should be noted that the handling device 90 can be set such that the movers 20 reach the handling stations 95 one by one and then handle the pole pieces 60 one by one, or it can be set such that after multiple movers 20 are transferred to the handling stations 95, the multiple pole pieces 60 are handled simultaneously. This application does not limit this, and it is specifically set according to the actual needs.

[0063] Exemplarily, the handling device 90 can be set such that after multiple movers 20 are transferred to the handling stations 95, the multiple pole pieces 60 are handled simultaneously. In this way, the efficiency of handling the pole pieces 60 is higher.

[0064] In some embodiments, refer to Figure 1 and combine with Figure 3 , Figure 3 which is the second structural schematic diagram of a pole piece cutting system provided by an embodiment of this application. When multiple movers 20 are located at the handling stations 95, the distance between two adjacent first fixing surfaces 21 is the first distance L1. When multiple movers 20 are located at the cutting stations 43, the distance between two adjacent first fixing surfaces 21 is the second distance L2, and the second distance L2 is greater than the first distance L1.

[0065] Since the handling device 90 requires a relatively large operating space during handling, this setting facilitates the handling device 90 to handle the pole pieces 60.

[0066] In some other embodiments, the first distance L1 can also be equal to the second distance L2.

[0067] In some embodiments, refer to again Figure 1 and combine with Figure 2 , the handling device 90 includes multiple handling members 91, and multiple second fixing surfaces 92 are respectively arranged on the multiple handling members 91.

[0068] In this way, by arranging multiple handling members 91, the pole pieces 60 transported on multiple movers 20 can be handled. In addition, the multiple handling members 91 can handle the pole pieces 60 more flexibly.

[0069] It should be noted that the number of the handling members 91 can be four, five, six, etc. This application does not limit this, and it is specifically set according to the actual needs.

[0070] Exemplarily, the number of the handling members 91 is six.

[0071] In some embodiments, the handling member 91 includes a second adsorption structure 93, and the second adsorption surface 94 of the second adsorption structure 93 forms the second fixing surface 92.

[0072] It should be noted that the second adsorption structure 93 can be vacuum adsorption, electro-adsorption, magnetic adsorption, chemical adsorption, etc. This application does not limit it, and it is specifically set according to the actual needs.

[0073] In some other embodiments, grippers can be arranged around the second fixing surface 92 of the handling member 91, and the pole piece 60 is fixed on the second fixing surface 92 through the grippers.

[0074] In some embodiments, along the conveying direction of the conveying device 30, the cutting station 43 is located upstream of the handling station 95.

[0075] Multiple rotors 20 first reach the cutting station 43 to cut and process the strip 50 to form the pole piece 60. Then, the multiple rotors 20 transport the pole piece 60 to the handling station 95 for handling. In this way, continuous processing and handling of the pole piece 60 can be achieved, and the processing efficiency of the pole piece 60 can be further improved.

[0076] In some embodiments, the conveying device 30 is a magnetic levitation conveying device 30.

[0077] In this way, by setting the conveying device 30 as a magnetic levitation conveying device 30, the movement of the rotor 20 can be controlled by a magnetic field, with high transmission accuracy, fast speed, good stability, and improved production efficiency.

[0078] In some other embodiments, the conveying device 30 can adopt a synchronous belt to drive the movement of the rotor 20.

[0079] In some embodiments, the conveying track 31 of the conveying device 30 is circular.

[0080] In this way, by setting the conveying track 31 of the conveying device 30 as circular, circular conveying of the rotor 20 can be achieved, enabling the rotor 20 to continuously circulate on the conveying track 31 and realizing continuous circular conveying of the production line. In addition, this setting can effectively utilize space, save floor space, and can achieve long-distance conveying to meet the requirements of different process flows.

[0081] In some other embodiments, refer to Figure 4 , Figure 4 which is the third structural schematic diagram of a pole piece cutting system provided by an embodiment of this application. The conveying track 31 of the conveying device 30 can also be square. In this way, the floor area in the length direction of the conveying device 30 can be reduced. Except for the position where the laser cutting device 40 is arranged, handling stations 95 can be arranged on the other three segments of the square conveying track 31. Or detection stations, etc. can be set according to different product processes.

[0082] In some embodiments, the number of the conveying tracks 31 of the conveying device 30 is multiple, the multiple conveying tracks 31 are arranged side by side, and the mover 20 is connected to the multiple conveying tracks 31.

[0083] In this way, the driving force of the conveying device 30 can be increased, the stability of the conveying device 30 can be improved, and the processing efficiency of the pole piece 60 can be further improved.

[0084] It should be noted that the number of the conveying tracks 31 of the conveying device 30 can be two, three, four, etc. The present application does not limit this, and it is specifically set according to the actual needs.

[0085] Exemplarily, refer to Figure 5 , Figure 5 FIG. 4 is a schematic structural diagram of a pole piece cutting system provided by an embodiment of the present application. The number of the conveying tracks 31 of the conveying device 30 can be two. The two conveying tracks 31 are located at both ends of the mover 20, so that both ends of the mover 20 can be supported, and the stability of the mover 20 is better.

[0086] It should be noted that in practical applications, due to the limitations of equipment accuracy or installation errors, an absolute parallel or vertical effect is difficult to achieve. In the present application, the descriptions of "vertical", "parallel" or "same direction" are not absolute limiting conditions, but mean that a vertical or parallel structural setting can be achieved within a preset error range and the corresponding preset effects can be achieved. In this way, the technical effects of the limiting features can be maximally realized, and the corresponding technical solutions are easy to implement and have high feasibility. For example, "vertical" includes absolute vertical and approximate vertical, and the acceptable deviation range of approximate vertical can be, for example, within 5°. "Parallel" includes absolute parallel and approximate parallel, and the acceptable deviation range of approximate parallel can be, for example, within 5°. "Same direction" includes absolute same direction and approximate same direction, and the acceptable deviation range of approximate same direction can be, for example, within 5°.

[0087] In the description of this specification, specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0088] The above is only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
