Then, the pole piece is rapidly cooled and shaped by the cooling mechanism, so that the thickness of the pole piece is fixed to prevent changes in the thickness of the pole piece, and the shaping can effectively prevent the pole piece from shrinking due to slow heat dissipation, and better fix the thickness of the pole piece. Then, the temperature-adjusted pole piece is conveyed to the die cutting mechanism for die cutting to form a lug, which can effectively prevent the pole piece from rebounding continuously after die cutting, avoid the lug from being misaligned when the pole piece is wound or stacked, and improve the production yield of the pole piece.

Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0039] In related technologies, pole pieces are typically die-cut to form tabs, which are then wound or stacked to ensure stable production and processing. However, the pole pieces are prone to continuous rebound after die-cutting, causing variations in their thickness and, in turn, causing tab misalignment during winding or stacking, impacting battery production quality and reducing the yield rate of the pole pieces.

[0040] It should be noted that after the electrode has undergone processes such as rolling, a certain amount of internal stress is easily accumulated in the electrode. Therefore, after the electrode is transferred from rolling to the die-cutting processing of the electrode ear, the internal stress of the electrode sheet is easily released continuously, causing the electrode sheet to continuously rebound and causing the thickness of the electrode sheet to change. Therefore, when winding or stacking the electrode sheet, it is easy for the thickness of the electrode sheet to be inconsistent with the set processing thickness of the electrode sheet, resulting in a certain misalignment of the wound or stacked electrode ear. The misalignment of the electrode ear will have a certain impact on the performance, safety and life of the battery, and reduce the production quality of the battery.

[0041] Based on the above considerations, in order to solve the problem of low electrode processing quality, the electrode processing device proposed in this application includes a heating mechanism, a cooling mechanism, a die-cutting mechanism and a conveying mechanism. The heating mechanism is configured to heat the electrode; the cooling mechanism is configured to cool the heated electrode; the die-cutting mechanism is configured to process the electrode ear on the electrode; the conveying mechanism is configured to convey the electrode so that the electrode passes through the heating mechanism, cooling mechanism and die-cutting mechanism in sequence.

[0042] In the embodiments of the present application, by using the conveying mechanism to convey the pole piece to pass through the heating mechanism, the cooling mechanism and the die-cutting mechanism in turn, the pole piece can be fully heated by the heating mechanism when passing through the heating mechanism, so that the pole piece rebounds in advance under the action of a certain temperature, fully releases the stress of the pole piece, and makes the thickness and other physical properties of the pole piece change to a certain extent; then the pole piece is rapidly cooled and shaped under the action of the cooling mechanism, so that the thickness of the pole piece is fixed to prevent the thickness of the pole piece from changing, and at the same time, the shaping can effectively prevent the pole piece from shrinking due to slow heat dissipation, and better fix the thickness of the pole piece. Then the temperature-adjusted pole piece is conveyed to the die-cutting mechanism for die-cutting processing to form the tab, which can effectively prevent the pole piece from continuously rebounding after die-cutting, avoid the tab misalignment when the pole piece is wound or stacked, and improve the production yield of the pole piece.

[0043] Referring to Figure 1 and Figure 2 In an embodiment of the present application, the pole piece processing device 100 includes a heating mechanism 10, a cooling mechanism 30, a die-cutting mechanism 50 and a conveying mechanism 70. The heating mechanism 10 is configured to heat the pole piece; the cooling mechanism 30 is configured to cool the heated pole piece; the die-cutting mechanism 50 is configured to process the tab on the pole piece; and the conveying mechanism 70 is configured to convey the pole piece so that the pole piece passes through the heating mechanism 10, the cooling mechanism 30 and the die-cutting mechanism 50 in turn.

[0044] In the present application, the heating mechanism 10, the cooling mechanism 30 and the die-cutting mechanism 50 can be arranged in sequence on the conveying path of the pole piece, so that the conveying mechanism 70 conveys the pole piece to pass through the heating mechanism 10, the cooling mechanism 30 and the die-cutting mechanism 50 in turn, to realize the die-cutting processing of the pole piece. The heating mechanism 10 can be an infrared heating device, an electromagnetic heating device, etc. When the pole piece passes through the heating mechanism 10, the heating mechanism 10 can transfer heat to the pole piece, or heat the pole piece through magnetic induction, so that the pole piece can be heated to a certain temperature, so that the pole piece can rebound under the action of a certain temperature to release stress, so that the thickness, porosity and other physical properties of the pole piece change to a certain extent, which usually causes the thickness and porosity of the pole piece to increase, etc.

[0045] Further, by conveying the heated pole piece into the cooling mechanism 30 through the conveying mechanism 70, the heat on the pole piece can be quickly removed in the cooling mechanism 30, so that the pole piece can be quickly cooled, the thickness change of the pole piece at high temperature can be fixed, and the shaping of the pole piece can be realized. In this way, the pole piece can be heated in advance to release the internal stress of the pole piece before die cutting processing through the heating mechanism 10 and the cooling mechanism 30, and the thickness of the pole piece after rebounding can be quickly cooled and fixed, and then the pole piece is conveyed to the die cutting mechanism 50 by the conveying mechanism 70 for die cutting processing to form the pole lug. At this time, since the internal stress of the pole piece is released in advance, the rebounding of the pole piece after die cutting processing can be effectively prevented, so that the pole piece can better achieve standard processing and discharging, avoid the misalignment of the pole lug due to the inconsistent thickness of the pole piece in the subsequent winding or stacking process, effectively improve the production yield of the pole piece, and further better improve the production quality of the battery, so that the battery can achieve better performance, safety and service life.

[0046] The die cutting mechanism 50 can adopt a laser cutting device, and the path and power of the laser can be adjusted according to the cutting requirements of the pole lug, so that the required pole lug can be stably processed on the pole piece. Alternatively, the die cutting mechanism 50 can adopt a die cutting device, and the die can be controlled to press on the pole piece to process the pole lug when the pole piece is conveyed through the die cutting mechanism 50. Of course, there are many ways to die cut the pole piece, and the specific structure of the die cutting mechanism 50 is not limited in the present application.

[0047] The technical scheme of the present application can convey the pole piece through the heating mechanism 10, the cooling mechanism 30 and the die cutting mechanism 50 in sequence by the conveying mechanism 70, so that the pole piece can be fully heated by the heating mechanism 10 when passing through the heating mechanism 10, the pole piece can rebound in advance under the action of a certain temperature, the stress of the pole piece can be fully released, and the thickness and other physical properties of the pole piece can change. Then, the pole piece is quickly cooled and shaped under the action of the cooling mechanism 30, so that the thickness of the pole piece is fixed to prevent the thickness of the pole piece from changing, and the thickness of the pole piece can be better fixed by shaping to prevent the pole piece from shrinking due to slow heat dissipation. Further, the pole piece after temperature adjustment is conveyed into the die cutting mechanism 50 for die cutting processing to form the pole lug, which can effectively prevent the pole piece from continuously rebounding after die cutting, avoid the misalignment of the pole lug when the pole piece is wound or stacked, and improve the production yield of the pole piece.

[0048] Referring to Figure 1 and Figure 2 In an embodiment of the present application, the pole piece processing device 100 further comprises a thickness measuring mechanism 90 and a controller. The thickness measuring mechanism 90 is configured to detect the thickness of the shaped pole piece. The controller is in signal connection with the thickness measuring mechanism 90 and the die cutting mechanism 50. The controller can receive the detection data of the thickness measuring mechanism 90 and correspondingly control the processing parameters of the die cutting mechanism 50.

[0049] In this embodiment, the thickness measuring mechanism 90 can be a visual detection device, and the thickness measuring mechanism 90 can be set on the transmission path of the electrode, so that the electrode can fall into the detection range of the thickness measuring mechanism 90 after being cooled and shaped by the cooling mechanism 30. The detection probe of the thickness measuring mechanism 90 is used to collect the side image of the electrode facing the side of the electrode, from which the thickness of the electrode after shaping can be obtained, so that the electrode processing device 100 can perform customized processing according to the thickness of each electrode.

[0050] Since the heating mechanism 10 and the cooling mechanism 30 are prone to certain temperature adjustment deviations after long-term continuous operation, it is easy to cause the heating temperature of different pole pieces by the heating mechanism 10 to be inconsistent, or it is easy to cause the cooling rate of different pole pieces by the cooling mechanism 30 to be inconsistent, which in turn causes the thickness of the pole pieces after the temperature adjustment by the heating mechanism 10 and the cooling mechanism 30 to be inconsistent. After the thickness measuring mechanism 90 detects the thickness of each finalized pole piece, the processing parameters of the die-cutting mechanism 50 can be better adjusted according to the thickness data of each pole piece, that is, the laser die-cutting power of the die-cutting mechanism 50 can be adjusted or the size of the cutting mold can be adjusted. In this way, according to the alignment requirements of the pole piece when the pole piece is wound, the die-cutting mechanism 50 can form pole pieces of corresponding sizes on the pole piece according to the thickness of the pole piece, better avoid the pole piece misalignment when the pole piece is wound, and ensure the stable production and processing of the pole piece.

[0051] By adopting the above scheme, the thickness of each electrode can be detected by the thickness measuring mechanism 90, and the processing parameters of the die-cutting mechanism 50 can be adjusted accordingly according to the thickness of the electrode, so that the die-cutting mechanism 50 can die-cut the electrode ears of corresponding sizes on the electrode according to the thickness of the electrode, so as to better avoid the misalignment of the electrode ears during the winding of the electrode, and further improve the production yield of the electrode.

[0052] See Figure 1 and Figure 2 In one embodiment of the present application, the die-cutting mechanism 50 includes a processing table 51 and a die-cutting component 53, and the die-cutting component 53 is arranged above the processing table 51; the heating mechanism 10 and the cooling mechanism 30 are arranged on the processing table 51 and are arranged in sequence along the transmission direction of the conveying mechanism 70.

[0053] In the embodiment, the processing table 51 can be docked with the conveying mechanism 70. For example, when the conveying mechanism 70 adopts a roller to convey the pole piece, conveying rollers can be arranged on opposite sides of the processing table 51, and when the processing surface of the processing table 51 is large, a plurality of conveying rollers can also be arranged on the processing table 51, so that the pole piece can pass through the heating mechanism 10, the cooling mechanism 30 and the die-cutting part 53 arranged on the processing table 51 in sequence under the action of the conveying mechanism 70, thereby ensuring the stable conveying and processing of the pole piece. For another example, when the conveying mechanism 70 uses a conveying belt to convey the pole piece, part of the structure of the conveying belt can be arranged on the processing table 51, thereby ensuring the stable conveying of the pole piece.

[0054] The processing table 51 is provided with a support structure, so that the heating mechanism 10, the cooling mechanism 30 and the die-cutting part 53 can be sequentially arranged on the processing table 51, or a plurality of mounting positions can be arranged on the processing table 51, and the mounting positions are arranged on the conveying path of the pole piece, and then the heating mechanism 10, the cooling mechanism 30 and the die-cutting part 53 can be sequentially assembled on the mounting positions, thereby ensuring the stable conveying and processing of the pole piece. Arranging the heating mechanism 10, the cooling mechanism 30 and the die-cutting part 53 on the processing table 51 can better integrate the plurality of components of the pole piece processing device 100 on the processing table 51, achieve better overall integrated design, and facilitate the adjustment and arrangement of the components of the pole piece processing device 100 during assembly, thereby achieving convenient assembly and transportation of the pole piece processing device 100.

[0055] The die-cutting part 53 can be a laser cutting head or a die-cutting machine, and a seat pad capable of bearing a certain laser energy or pressure can be arranged at the position of the die-cutting part 53 on the processing table 51, so as to ensure the stability and reliability of the overall structure of the die-cutting mechanism 50.

[0056] By arranging the heating mechanism 10 and the cooling mechanism 30 on the processing table 51 and arranging the die-cutting mechanism 50 above the processing table 51 to cut the pole piece, the overall design of the pole piece processing device 100 can be better achieved, the overall transportation and installation of the pole piece processing device 100 can be facilitated, the assembly process of the pole piece processing device 100 can be reduced, and the practicability of the pole piece processing device 100 can be further improved.

[0057] In an embodiment of the present application, the heating mechanism 10 is an infrared heating device.

[0058] In this embodiment, the infrared heating device can be arranged at a certain distance from the upper and lower surfaces of the electrode on the transmission path of the electrode. The infrared heating device can be used to radiate heat on the upper and lower surfaces of the electrode, so that the electrode is subjected to a certain amount of heat and rebounds, so that the thickness of the electrode changes and the internal stress of the electrode is released in advance. The infrared heating device transfers heat to the electrode through infrared radiation, which can avoid contact between the heating mechanism 10 and the electrode, and further avoid the possibility of the heating mechanism 10 scratching off part of the structure of the electrode when it is heated to a certain temperature and softened, thereby ensuring the overall structural stability of the electrode after processing and better improving the production yield of the electrode.

[0059] By adopting the above scheme, the electrode is heated by an infrared heating device, and heat radiation can be applied to the electrode, realizing non-contact heating between the heating mechanism 10 and the electrode, which is beneficial to avoid contact between the electrode and the heating mechanism 10 after being heated and softened, reducing the wear of the electrode and better improving the production yield of the electrode.

[0060] See Figure 1 In one embodiment of the present application, the conveying mechanism 70 includes a unwinding device 71 and a winding device 73. The unwinding device 71 is configured to release the electrode to be processed, and the winding device 73 is configured to wind up the processed electrode; the heating mechanism 10, the cooling mechanism 30 and the die-cutting mechanism 50 are arranged between the unwinding device 71 and the winding device 73, and are arranged in sequence along the transmission direction of the conveying mechanism 70.

[0061] In this embodiment, the unwinding device 71 and the winding device 73 can be rollers that can rotate on their own. The electrode to be processed can be wound into a material roll and loaded into the unwinding device 71. The electrode can be released by the rotation of the unwinding device 71. Then, the electrode can be passed through the heating mechanism 10, the cooling mechanism 30 and the die-cutting mechanism 50 in sequence through rollers or conveyor belts, and then the electrode is conveyed to the winding device 73 to be wound up, thereby realizing stable conveying and processing of the electrode; or, the electrode material can be rolled into the unwinding device 71, and one end of the electrode can be connected to the winding device 73. The synchronous rotation of the unwinding device 71 and the winding device 73 can be utilized to enable the conveying mechanism 70 to stably convey the electrode, and the electrode can pass through the heating mechanism 10, the cooling mechanism 30 and the die-cutting mechanism 50 in sequence during the conveying process, thereby realizing stable conveying and processing of the electrode.

[0062] Under the action of the unwinding device 71 and the winding device 73, the electrode to be processed can be automatically released for transmission processing, and the electrode after the die-cutting process can be automatically wound and unloaded, which can better improve the degree of automation of the electrode processing device 100, realize better automated operation of the electrode processing device 100, and further improve the practicality and processing efficiency of the electrode processing device 100.

[0063] With the above scheme, the releasing device 71 and the winding device 73 can continuously release the processed pole piece and wind the processed pole piece, guaranteeing the continuous operation of the pole piece processing device 100, and better realizing the automatic processing operation of the pole piece processing device 100, and further improving the practicability and structural reliability of the pole piece processing device 100.

[0064] Referring to Figure 3 and Figure 9 The application further provides a control method of the pole piece processing device 100, which is applied to the pole piece processing device 100 of any of the above embodiments, and the control method of the pole piece processing device 100 comprises the following steps: Step S10, starting the conveying mechanism 70 to make the conveying mechanism 70 convey the pole piece; When the pole piece processing device 100 receives the running start signal, the conveying mechanism 70 can be controlled to start to make the pole piece to be processed arranged on the pole piece conveyed by the conveying mechanism 70 to the heating mechanism 10, the cooling mechanism 30 and the die-cutting mechanism 50 in sequence, so as to appropriately control the temperature of the pole piece and perform die-cutting processing. The conveying mechanism 70 can convey the pole piece through a plurality of rollers arranged at intervals, or can stably convey the pole piece through a conveying belt, and the structure of the conveying mechanism 70 is not limited in the application.

[0065] Step S30, controlling the heating mechanism 10 to start to make the heating mechanism 10 heat the pole piece to change the thickness of the pole piece; The heating mechanism 10 can be quickly started to preheat when the pole piece processing device 100 is running, so that the heating mechanism 10 can quickly generate heat under the control of a certain processing power, and then the heat can be quickly transferred to the pole piece by the heating mechanism 10 when the pole piece passes through the heating mechanism 10, so that the pole piece is heated to rebound, and the internal stress of the pole piece is fully released. At this time, the physical properties of the pole piece such as thickness change, so that the thickness of the pole piece increases, and the pole piece is rebounded in advance before die-cutting processing. The heating mechanism 10 can indirectly transfer heat to the pole piece through heat radiation, and of course can directly transfer heat to the pole piece through a heat conduction structure.

[0066] Step S50, controlling the cooling mechanism 30 to start to make the cooling mechanism 30 cool the heated pole piece to make the pole piece shape; After the pole piece is heated and rebounded by the heating mechanism 10 to increase the thickness of the pole piece, the pole piece is quickly transferred to the cooling mechanism 30 by the conveying mechanism 70, and the pole piece can be quickly cooled in the cooling mechanism 30 to shape the pole piece, so that the structure of the pole piece after the stress is fully released can be fixed, and the pole piece is effectively prevented from rebounding again in the subsequent processing process, and the reliable processing of the pole piece is ensured. The cooling mechanism 30 can use air cooling, use a fan to generate low-temperature airflow to act on the pole piece to cool and cool the pole piece; or can use liquid cooling, one end of the heat-conducting material contacts the pole piece, and the other end of the heat-conducting material is arranged in contact with the flowing cooling liquid, so that the heat of the pole piece can be quickly transferred to the liquid cooling device through the heat-conducting material and carried away, realizing the rapid cooling and cooling of the pole piece.

[0067] Step S70, control the die-cutting mechanism 50 to start, so that the die-cutting mechanism 50 processes the pole piece to form the pole tab.

[0068] When the conveying mechanism 70 conveys the pole piece after cooling and shaping to the die-cutting mechanism 50, the die-cutting mechanism 50 can be controlled to cut and process the pole piece at an appropriate position of the pole piece to form the pole tab of the pole piece. A visual observation module can be arranged in the die-cutting mechanism 50 to identify and position the passing pole piece, so as to ensure that the die-cutting mechanism 50 stably processes the pole tab on the pole piece; or an infrared positioning module can be arranged in the die-cutting mechanism 50 to accurately position the position of the pole tab that needs to be processed, so as to ensure the stable cutting processing of the die-cutting mechanism 50.

[0069] By heating the pole piece by the heating mechanism 10 and rapidly cooling the heated pole piece by the cooling mechanism 30 to shape the pole piece, the pole piece can rebound in advance under the action of heat, fully release internal stress, and through temperature reduction and shaping, after the pole piece is processed by the die-cutting mechanism 50 to form the pole tab, the thickness of the pole piece is effectively prevented from changing again, so that the pole piece can maintain a stable thickness state for winding or stacking, effectively avoiding the pole tab dislocation after the pole piece is wound or stacked, ensuring the production quality of the battery, better improving the performance, safety and life of the battery, and effectively improving the production and processing yield of the pole piece.

[0070] Referring to Figure 4 In an embodiment of the present application, the pole piece processing device 100 further comprises a thickness measuring mechanism 90, and after the step of controlling the cooling mechanism 30 to start and cool the heated pole piece to shape the pole piece, the pole piece processing device 100 further comprises: Step S61, control the thickness measuring mechanism 90 to start to detect and obtain the thickness information of the pole piece; The thickness measuring mechanism 90 can acquire a side image of the pole piece after being cooled and shaped by the cooling mechanism 30, and accurately identify the thickness of the pole piece at this time from the side image; or a reference position can be set on the workbench, and the thickness of the pole piece after being cooled and shaped by the cooling mechanism 30 can be obtained by detecting the distance between the pole piece and the reference position.

[0071] In step S63, the processing parameters of the die-cutting mechanism 50 are adjusted according to the thickness information.

[0072] Since the heating mechanism 10 and the cooling mechanism 30 are likely to have a certain temperature adjustment deviation after operating for a certain period of time, the thickness of the pole pieces conveyed in the same batch after shaping may not be consistent, which may cause the pole tabs to be misaligned when being wound. Therefore, the thickness information of the pole pieces after shaping can be obtained by the thickness measuring mechanism 90, and the temperature regulation condition of the pole pieces can be known from the thickness information, so that the processing parameters of the die-cutting mechanism 50 can be adjusted according to the thickness of the pole pieces, so that the die-cutting mechanism 50 can form pole tabs of corresponding sizes according to the thickness of the pole pieces, thereby further avoiding the misalignment of the pole tabs when the pole pieces are wound, and better improving the production and processing yield of the pole pieces.

[0073] For example, when laser cutting is used, the moving path and power of the cutting laser can be adjusted to cut the pole pieces to form pole tabs of corresponding sizes; for example, when the die-cutting mechanism 50 uses die cutting, the die position can be adjusted to cut the pole pieces to form pole tabs of corresponding sizes.

[0074] By using the above scheme, the thickness of each pole piece after shaping is accurately detected by the thickness measuring mechanism 90, so that the die-cutting mechanism 50 adjusts the processing parameters according to the thickness of the pole pieces, so that the die-cutting mechanism 50 cuts and processes the pole pieces to form pole tabs of corresponding sizes, better avoids the misalignment of the pole tabs when the pole pieces are wound or stacked, further improves the production and processing yield of the pole pieces, and improves the production quality of the battery.

[0075] Referring to Figure 5 In an embodiment of the present application, the pole piece processing device 100 further comprises a controller, and the controller stores a die-cutting processing database. In the step of adjusting the processing parameters of the die-cutting mechanism 50 according to the thickness information, the following steps are included: In step S631, the controller receives the thickness information, and confirms the corresponding adjustment parameters from the die-cutting processing database according to the thickness information. It can be understood that the die cutting processing database can record a plurality of pole piece thickness ranges corresponding to the pole lug die cutting size. According to the experimental or calculated measurement of the pole lug misalignment error value of the pole piece of different thickness when winding, the corresponding pole lug size data of the pole piece of various thicknesses is deduced according to the result, and these experimental data or calculation data are summarized to form the die cutting processing database, so that the die cutting mechanism 50 can better customize the die cutting size of the pole lug according to the thickness of the pole piece, and better avoid the misalignment of the pole lug when winding or stacking the pole piece.

[0076] According to the detected thickness of the pole piece, the corresponding pole lug size can be found in the die cutting processing database. At this time, the controller can send control parameters to control the action of the die cutting mechanism 50 according to the pole lug size. The control parameters can be, but are not limited to, displacement control parameters of the die cutting component 53, cutting output power of the die cutting component 53, etc., so as to ensure that the die cutting mechanism 50 can stably process the corresponding size of the pole lug on the pole piece.

[0077] Step S632, send a control signal to the die cutting mechanism 50 according to the control parameter to control the die cutting size of the die cutting mechanism 50.

[0078] The control signal records the component movement value required by the die cutting mechanism 50 to control, so that the die cutting mechanism 50 can control the die cutting component 53 to process the pole piece according to the corresponding die cutting route or die cutting position, adjust the die cutting size of the die cutting mechanism 50, and accurately process the corresponding size of the pole lug on the pole piece. The die cutting mechanism 50 can ensure accurate and reliable processing of the pole piece, better avoid the misalignment of the pole lug when winding the pole piece, and further improve the practicability and structural reliability of the pole piece processing device 100.

[0079] According to the thickness of the shaped pole piece, the control parameter of the die cutting mechanism 50 is quickly confirmed from the die cutting processing database, so as to accurately control the die cutting size of the die cutting structure. The pole piece processing device 100 can quickly respond to the control operation of the die cutting mechanism 50, so that the die cutting mechanism 50 can stably process the corresponding size of the pole lug for pole pieces of different thicknesses, better avoid the misalignment of the pole lug when winding or stacking the pole lug, and further improve the practicability and reliability of the pole piece processing device 100.

[0080] Referring to Figure 6 In an embodiment of the present application, after the step of starting the thickness measuring mechanism 90 to enable the thickness measuring mechanism 90 to detect and obtain the thickness information of the pole piece, the following steps are further included: Step S621, obtaining thickness deviation information according to the thickness information and the set thickness threshold value; It should be noted that in the experiment of the thickness change of the pole piece after rebounding due to heating and being shaped after cooling, even if the thickness of the shaped pole piece is affected by the difference between the heating and cooling temperatures, the thickness of the shaped pole piece may have a certain deviation, but the thickness value of the shaped pole piece is generally within a certain thickness value range, and then the maximum and minimum values of the thickness value range can be set as the set thickness threshold. After the thickness information of the pole piece is detected by the thickness detection mechanism 90, the thickness information of the pole piece can be compared with the set thickness threshold to confirm whether the detected thickness information falls within the set thickness threshold range, and the thickness deviation information between the thickness information and the set thickness threshold is obtained. For example, the thickness deviation information when the thickness information is less than the minimum value of the set thickness threshold can be that the thickness of the pole piece is too small, the thickness deviation information when the thickness information is greater than the maximum value of the set thickness threshold can be that the thickness of the pole piece is too large, and the thickness deviation information when the thickness information is greater than the minimum value of the set thickness threshold and less than the maximum value of the set thickness threshold can be that the thickness of the pole piece is not deviated. When the result of the thickness of the pole piece being too small is obtained, it can be indicated that the pole piece is not heated sufficiently to rebound, and when the result of the thickness of the pole piece being too large is obtained, it can be indicated that the pole piece is heated too much and has a certain probability of being damaged, and when the result of the thickness of the pole piece being not deviated is obtained, it can be indicated that the pole piece is heated normally.

[0081] In step S622, the conveying speed of the conveying mechanism 70 is adjusted according to the thickness deviation information.

[0082] The thickness deviation information obtained can reflect the processing state of the pole piece after the pole piece passes through the heating mechanism 10 and the cooling mechanism 30, and at this time, the conveying speed of the conveying mechanism 70 can be adjusted according to the feedback pole piece state, so that the pole piece can be subjected to more stable and stable adjustment. When the thickness deviation information is that the thickness of the pole piece is too small, the pole piece is not heated sufficiently, and the conveying speed of the conveying mechanism 70 can be appropriately slowed down to prolong the time of the pole piece passing through the heating mechanism 10, so that the pole piece can be heated sufficiently to rebound; when the thickness deviation information is that the thickness of the pole piece is too large, the pole piece is heated too much, and the conveying speed of the conveying mechanism 70 can be appropriately increased to shorten the time of the pole piece passing through the heating mechanism 10, so that the pole piece can sufficiently rebound under the action of appropriate heat; and when the thickness deviation information is that the thickness of the pole piece is not deviated, the conveying speed of the conveying mechanism 70 at this time can be stably maintained to ensure the production and processing yield of the pole piece.

[0083] By using the above scheme, the thickness deviation information is obtained according to the thickness information of the shaped pole piece and the set thickness threshold, and the thickness change of the pole piece after the temperature adjustment of the heating mechanism 10 and the cooling mechanism 30 can be fed back, so that the conveying speed of the conveying mechanism 70 of the pole piece processing device 100 can be appropriately adjusted, so that the pole piece can be heated sufficiently to rebound, and the production and processing yield of the pole piece can be better improved.

[0084] Referring toFigure 7 In one embodiment of the present application, before the step of controlling the heating mechanism 10 to start and causing the heating mechanism 10 to heat the electrode to change the thickness of the electrode, the method further includes: Step S21, obtaining the material information of the electrode; It is understandable that the heat resistance of pole pieces made of different materials has certain differences. Before the pole piece processing device 100 is operated, the controller can obtain the material information of the pole piece being processed to obtain information such as the temperature range that the pole piece can withstand and the initial thickness of the pole piece, so as to better regulate each component according to the material information of the pole piece and ensure stable processing of the pole piece.

[0085] Step S22: regulating the heating power of the heating mechanism 10 according to the material information.

[0086] The maximum temperature value that the electrode can withstand and the temperature value at which the internal stress of the electrode is fully released and rebound can be known from the material information of the electrode. The temperature required for heating by the heating mechanism 10 can be confirmed based on this information, and then the heating power of the heating mechanism 10 can be adjusted so that the heating mechanism 10 can stably reach the heating temperature, thereby achieving stable heating of the electrode, ensuring that the internal stress of the electrode can be fully released and rebound when passing through the heating mechanism 10, better preventing the electrode from rebounding again after die-cutting processing, and further avoiding the misalignment of the electrode ears during winding, thereby improving the practicality and reliability of the electrode processing device 100.

[0087] By adopting the above scheme, the heating temperature corresponding to the electrode is confirmed according to the material information of the electrode to be processed, so that the heating power of the heating mechanism 10 can be adjusted so that the heating mechanism 10 can stably reach the heating temperature, ensuring that the electrode can be stably heated and rebounded in the heating mechanism 10, thereby achieving stable processing of the electrode, better avoiding the misalignment of the electrode ear when the electrode is wound, and further improving the production and processing yield of the electrode.

[0088] See Figure 8 In one embodiment of the present application, the heating mechanism 10 is provided with a temperature measuring module. After the step of controlling the heating mechanism 10 to start and heat the electrode to change the thickness of the electrode, the method further includes: Step S41, determining a set temperature according to material information; It can be understood that the heating temperature required for the electrode to fully rebound can be obtained from the electrode material information of the processing. At this time, the heating temperature can be set as the set temperature so that the controller can feedback adjust the heating mechanism 10 according to the set temperature to ensure sufficient heating of the electrode.

[0089] Step S42, controlling the temperature measurement module to detect the heating temperature of the electrode; The temperature measuring module can adopt an infrared temperature measuring device or a contact type temperature measuring probe, etc. The temperature measuring module can monitor the heating temperature of the pole piece in real time to determine whether the pole piece can stably reach the set temperature, and the controller can adjust the heating mechanism 10 according to the temperature measurement result.

[0090] In step S43, a temperature difference regulation signal is obtained according to the heating temperature and the set temperature. According to the measured heating temperature of the pole piece surface, the heating temperature can be compared with the set temperature to obtain the temperature deviation of the actual heating of the pole piece, so that the controller can obtain a temperature difference regulation signal according to the temperature deviation. When the heating temperature is less than the set temperature, a temperature difference regulation signal for increasing the heating power can be output; when the heating temperature is greater than the set temperature, a temperature difference regulation signal for reducing the heating power can be output; and when the heating temperature is equal to the set temperature, a temperature difference regulation signal for maintaining the heating power can be output.

[0091] In step S44, the heating power of the heating mechanism 10 is regulated according to the temperature difference regulation signal.

[0092] Due to the influence of the service life of the equipment and the environmental temperature, the temperature reached by the heating mechanism 10 during operation can have a certain deviation from the set temperature required by the pole piece. According to the temperature measurement of the pole piece, the temperature difference regulation signal obtained by analyzing the measured heating temperature and the set temperature can enable the heating mechanism 10 to receive the signal and make certain feedback adjustment to the heating power, so that the heating mechanism 10 can be stably regulated to the set temperature required by the pole piece, so that the pole piece can fully release the internal stress and rebound in the appropriate heating environment, better realize the pre-rebound operation of the pole piece, prevent the pole piece from continuously rebounding after die cutting, better avoid the misalignment of the pole lug when the pole piece is wound or stacked, and further improve the practicability and reliability of the pole piece processing device 100.

[0093] By using the above scheme, the heating temperature of the pole piece is monitored in real time by the temperature measuring module, the measured temperature can be analyzed according to the pre-set temperature, it can be confirmed whether the heating mechanism 10 forms a suitable heating environment for the pole piece, and the heating power of the heating mechanism 10 can be adjusted in time according to the temperature difference regulation signal obtained by analysis, so as to realize the feedback adjustment of the heating mechanism 10, so that the pole piece can fully rebound in the heating mechanism 10, better avoid the misalignment of the pole lug when the pole piece is wound, and further improve the production quality of the battery.
