[0043] With the vigorous development of new energy automobile industry, the automobile industry has put forward higher requirements for the endurance, safety and charging speed of lithium batteries. As a kind of frontier innovative technology, solid-state battery is like a powerful innovative power impacting the field of electric vehicles.

[0044] In the process of cutting solid-state battery, there will be more or less some waste gas, such as: in the process of cutting sulfide solid-state battery, the pole piece will produce hydrogen sulfide and other waste gas. The traditional cutting equipment usually concentrates each process together, from the release of the pole piece to the cutting of the pole piece, and then to the winding of the pole piece. Each process is not separately partitioned and lacks the corresponding exhaust system, so that the generated waste gas cannot be discharged in time.

[0045] At the same time, the operator operates frequently in the process of releasing the pole piece and winding the pole piece, such as: performing the operation of up and down pole piece winding, therefore, the operator is easy to contact with the waste gas in the above two processes, which has certain hidden danger.

[0046] Therefore, in view of the problem that the operator is easy to contact with the waste gas in the traditional cutting equipment, the present application provides a cutting equipment. In the structural design, different functions are reasonably partitioned, and the feeding module and the winding module are distributed in separate first and second warehouse bodies to provide a separate closed area for the feeding module and the winding module. Since the first and second warehouse bodies are provided with exhaust devices, the exhaust devices can be used to exhaust the waste gas in the first and second warehouse bodies, reduce the concentration of waste gas in the first and second warehouse bodies, effectively reduce the contact risk of the operator and the waste gas in the production process, and realize safe production.

[0047] The die-cutting device provided by the present application can be not only suitable for die-cutting of solid-state batteries, but also suitable for die-cutting of other types of batteries, such as die-cutting of pole pieces of liquid-state batteries.

[0048] According to some embodiments of the present application, referring to FIG. 1, the present application provides a die-cutting device 100, which comprises a die-cutting device 10 and an exhaust device 20. The die-cutting device 10 comprises a die-cutting module 14, a feeding module 11 for providing material 300 to the die-cutting module 14, and a winding module 15 for winding the material 300 output by the die-cutting module 14. The exhaust device 20 comprises an exhaust assembly 24, a first warehouse body 21, and a second warehouse body 22 located outside the first warehouse body 21. The feeding module 11 is arranged in the first warehouse body 21, and the winding module 15 is arranged in the second warehouse body 22. The first warehouse body 21 and the second warehouse body 22 are both provided with the exhaust assembly 24, which is used to exhaust waste gas out of the first warehouse body 21 or the second warehouse body 22.

[0049] The feeding module 11 refers to a device that can provide material 300 outward, which can include a winding-off roller to release the material 300 in a roll outward. The die-cutting module 14 refers to a device that can die-cut the material 300 output by the feeding module 11. Taking battery die-cutting as an example, the material 300 can be a pole piece 200, which comprises a coated area 210 coated with active material and a blank area 220 not coated with active material. For details, please refer to FIG. 2. During the die-cutting process, the blank area 220 needs to be cut by the die-cutting module 14 to form a tab 230 with a desired shape. Of course, in some embodiments, the feeding module 11 can provide a plurality of pole pieces 200 connected to each other to the die-cutting module 14, and the die-cutting module 14 can then perform slitting on the connection between the two pole pieces 200 to achieve one-out-multiple operation.

[0050] The winding module 15 refers to a device that can wind the die-cut material 300, which can include a winding roller. When the material 300 is die-cut by the die-cutting module 14, the winding roller can use its rotation to wind the material 300 on the winding roller to form a roll structure.

[0051] The first and second warehouse bodies 21 and 22 are structures with certain space inside, which can correspond to the feeding module 11 and the winding module 15 respectively, so as to achieve the purpose of partitioning the feeding module 11 and the winding module 15. Since the feeding module 11 and the winding module 15 are contacted more frequently by the operator, for example, the operator needs to install the material 300 on the feeding module 11, and then take the wound material 300 from the winding module 15. Therefore, the feeding module 11 and the winding module 15 are individually sealed, which is convenient for individually pumping and exhausting the feeding module 11 and the winding module 15, and is beneficial to reducing the exhaust gas generated in the feeding module 11 and the winding module 15 in time.

[0052] When the feeding module 11 and the winding module 15 are arranged in the first and second warehouse bodies 21 and 22 respectively, the material 300 can be extended from the gap on the first warehouse body 21 and installed in the die-cutting module 14, and then extended from the gap on the second warehouse body 22 and installed in the winding module 15. Of course, openings for the material 300 to enter or exit can also be arranged on the first and second warehouse bodies 21 and 22 respectively.

[0053] In addition, the first and second warehouse bodies 21 and 22 can be spaced apart from each other or connected to each other. For example, the first and second warehouse bodies 21 and 22 are connected to each other, and the internal space of the first warehouse body 21 and the internal space of the second warehouse body 22 are separated by a partition structure, that is, the first and second warehouse bodies 21 and 22 share a partition structure.

[0054] The pumping and exhausting assembly 24 is a device that can pump and exhaust the exhaust gas in the first or second warehouse body 21 or 22, so as to reduce the concentration of the exhaust gas in the first or second warehouse body 21 or 22, which can be but is not limited to a vacuum pump and the like.

[0055] In addition, it should be noted that in order to stably transmit the material 300, a plurality of rollers can be arranged along the conveying direction X of the material 300 to support the transmission of the material 300.

[0056] In this way, the exhaust device 20 can exhaust the exhaust gas in the first and second warehouse bodies 21 and 22, reduce the concentration of the exhaust gas in the first and second warehouse bodies 21 and 22, effectively reduce the risk of contact between the operator and the exhaust gas during production, and realize safe production.

[0057] According to some embodiments of the present application, referring to FIG. 3, each pumping and exhausting assembly 24 includes an inlet pipe 241 and an exhaust pipe 242, which are communicated with the first or second warehouse body 21 or 22. The inlet pipe 241 is used for the flow of external air, and the exhaust pipe 242 is used for the exhaust of exhaust gas.

[0058] During the extraction and discharge process, external air flows into the first chamber 21 or the second chamber 22 through the inlet pipe 241, and exhaust gas is discharged out of the first chamber 21 or the second chamber 22 through the discharge pipe 242, realizing the circulation of the air flow in and out of the first chamber 21 or the second chamber 22, and reducing the concentration of the exhaust gas in the first chamber 21 or the second chamber 22. The exhaust gas can be uniformly transported to a treatment device for purification treatment.

[0059] The extraction and discharge assembly 24 can further include a vacuum pump, which provides power for the air flow in the first chamber 21 and the second chamber 22. Meanwhile, the extraction and discharge assembly 24 can also not be separately provided with a vacuum pump, and in this case, the discharge pipe 242 needs to be in communication with external air extraction equipment.

[0060] In this way, the introduction of the inlet pipe 241 and the discharge pipe 242 facilitates the discharge of the exhaust gas in the first chamber 21 and the second chamber 22, reduces the concentration of the exhaust gas, and effectively reduces the possibility of personnel contacting the exhaust gas.

[0061] According to some embodiments of the present application, referring to FIG. 3, in the height direction of the extraction and discharge device 20, the communication position of the inlet pipe 241 on the first chamber 21 or the second chamber 22 is higher than the communication position of the discharge pipe 242.

[0062] The communication position of the inlet pipe 241 is higher than the communication position of the discharge pipe 242, which means that in the first chamber 21 and the second chamber 22, external air flows in from the top and exhaust gas is discharged from the bottom. Taking a sulfide solid-state battery as an example, during the die cutting process, the electrode sheet 200 will generate part of the hydrogen sulfide exhaust gas, which is heavier than air and is easy to sink to the bottom of the first chamber 21 or the second chamber 22. Therefore, by raising the inlet pipe 241 and lowering the discharge pipe 242, the incoming air can discharge the exhaust gas from the discharge pipe 242.

[0063] In some examples, referring to FIG. 3, the top of the first chamber 21 and the second chamber 22 is communicated with the inlet pipe 241, and the bottom of the first chamber 21 and the second chamber 22 is communicated with the discharge pipe 242.

[0064] In this way, the positions of the inlet pipe 241 and the discharge pipe 242 are reasonably distributed, making the air flow in the first chamber 21 and the second chamber 22 more smooth, facilitating the incoming air to discharge the exhaust gas from the discharge pipe 242, and further reducing the concentration of the exhaust gas.

[0065] According to some embodiments of the present application, referring to FIG. 3, the extraction and discharge device 20 further includes a detector 25, and the first chamber 21 and the second chamber 22 are each provided with a detector 25, which is used to detect the concentration of the exhaust gas.

[0066] The detector 25 refers to a device capable of detecting the concentration value of the exhaust gas in the first bin body 21 and the second bin body 22. For example, for a sulfide solid-state battery, the detector 25 can be, but is not limited to, a hydrogen sulfide gas concentration detector 25, etc. The installation position of the detector 25 in the first bin body 21 and the second bin body 22 can be various, such as being fixed at the top, bottom or middle position of the first bin body 21 or the second bin body 22, etc.

[0067] In order to facilitate observation of the concentration of the exhaust gas, the detector 25 can be electrically connected with the display screen, so that the display screen displays the data obtained by the detector 25 in real time. When the data of the detector 25 is greater than the set value, the exhaust and discharge capacity of the exhaust and discharge assembly 24 can be increased, so that the concentration value of the exhaust gas in the first bin body 21 and the second bin body 22 is lower than the set value.

[0068] In this way, the detector 25 is introduced to monitor the concentration value of the exhaust gas in the first bin body 21 and the second bin body 22 in real time, which facilitates control of the concentration value of the exhaust gas in the first bin body 21 and the second bin body 22 to be lower than the set value, and further improves the safety of production.

[0069] According to some embodiments of the present application, referring to FIG. 3, the exhaust and discharge device 20 further comprises a differential pressure gauge 26, and the first bin body 21 and the second bin body 22 are each provided with a differential pressure gauge 26. The differential pressure gauge 26 is used to detect the internal and external pressure difference of the first bin body 21 or the second bin body 22.

[0070] When the internal pressure of the first bin body 21 or the second bin body 22 is greater than the external pressure, the exhaust gas is easy to overflow out of the first bin body 21 or the second bin body 22. Therefore, the differential pressure gauge 26 is arranged to obtain the internal and external pressure difference of the first bin body 21 and the second bin body 22 in time, so as to reduce the phenomenon of self-overflow of the exhaust gas.

[0071] The differential pressure gauge 26 refers to a device capable of obtaining the internal and external pressure difference of the first bin body 21 or the second bin body 22, such as, but not limited to, a differential pressure gauge. It should be noted that when the internal pressure of the first bin body 21 or the second bin body 22 is greater than the external pressure, the exhaust and discharge capacity of the exhaust and discharge assembly 24 can be appropriately increased, or the flow of external air into the first bin body 21 or the second bin body 22 can be reduced, so that the first bin body 21 or the second bin body 22 is in a state of micro-negative pressure.

[0072] In this way, the differential pressure gauge 26 is introduced to obtain the internal and external pressure difference of the first bin body 21 and the second bin body 22 in time, so as to reduce the phenomenon of self-overflow of the exhaust gas.

[0073] According to some embodiments of the present application, referring to FIG. 4, the exhaust and discharge device 20 further comprises an operating sleeve 28, and the first bin body 21 and the second bin body 22 are each provided with an operating hole 27. The operating sleeve 28 is located in the first bin body 21 or the second bin body 22 and is sealingly connected to the outer periphery of the operating hole 27.

[0074] When manual operation is needed for the feeding module 11 or the winding module 15, the hand can be inserted into the operation sleeve 28, so that the operator can contact the feeding module 11 or the winding module 15. The position of the operation sleeve 28 on the first warehouse body 21 or the second warehouse body 22 can be determined according to the position of the feeding module 11 or the winding module 15 where manual operation is needed, for example, the operation sleeve 28 is arranged at a position corresponding to the loading, unloading, belt connection, and corner waste cleaning of the first warehouse body 21 or the second warehouse body 22.

[0075] In this way, the operator can conveniently perform corresponding operations on the feeding module 11 or the winding module 15 through the operation sleeve 28, the number of door openings of the first warehouse body 21 or the second warehouse body 22 is reduced, and the probability of personnel contacting waste gas is further reduced.

[0076] According to some embodiments of the present application, referring to FIG. 5, the die-cutting device 10 further comprises a first vision assembly 13 located at the upstream end of the die-cutting module 14, which is used to detect the appearance of the material 300 before entering the die-cutting module 14.

[0077] The first vision assembly 13 is located at the upstream end of the die-cutting module 14, which means that the first vision assembly 13 acts on the material 300 before the die-cutting module 14, so that the appearance detection of the material 300 is performed before die-cutting. If the appearance of the material 300 does not meet the production requirements, for example, defects such as damage, powder loss, and fracture occur on the pole piece 200, the first vision assembly 13 can feed back information to the control system, and the control system controls the feeding module 11 to stop working and stops the material 300 from continuing to be transported into the die-cutting module 14. The control system can be, but is not limited to, an editable logic controller, an industrial computer, a single-chip microcomputer, etc.

[0078] The first vision assembly 13 refers to a device that can obtain image information of the appearance of the material 300, for example, which can be, but is not limited to, a CCD (charge coupled device) camera, etc.

[0079] It should be noted that the upstream end and the downstream end are both referred to the running direction X of the material 300, for example, the upstream end of the die-cutting module 14 refers to one end of the die-cutting module 14 in the direction opposite to the running direction X; and the downstream end of the die-cutting module 14 refers to one end of the die-cutting module 14 in the running direction X.

[0080] In this way, the first vision assembly 13 is introduced to perform appearance detection on the material 300 before die-cutting, so that the material 300 with defects is stopped before the die-cutting module 14, the number of unqualified products is reduced, and the production yield is improved.

[0081] According to some embodiments of the present application, referring to FIG. 5, the feeding module 11 comprises a unwinding assembly 111 and a splicing platform 112, the unwinding assembly 111 is used to release the material 300 to the splicing platform 112, the first vision assembly 13 is arranged in the first warehouse body 21 and located at the downstream end of the splicing platform 112.

[0082] The unwinding assembly 111 refers to the equipment for releasing the material 300, which can comprise a unwinding roller. The splicing platform 112 refers to the equipment for reconnecting the broken material 300, since the specific structure of the unwinding assembly 111 and the splicing platform 112 is not the object to be improved in the present embodiment, the specific structure of the unwinding assembly 111 and the splicing platform 112 will not be described in detail here.

[0083] The first vision assembly 13 is located at the downstream end of the splicing platform 112, which indicates that the first vision assembly 13 can detect not only the original appearance of the material 300, but also the splicing quality of the splicing platform 112. When the splicing quality of the material 300 on the splicing platform 112 does not meet the production requirements, the first vision assembly 13 sends information to the control system, and the control system controls the unwinding assembly 111 to provide feeding, so that the operator can repair the splicing platform 112.

[0084] The space near the side of the splicing platform 112 close to the unwinding assembly 111 is small, if the first vision assembly 13 is arranged at the upstream end of the splicing platform 112, the small space will result in that the first vision assembly 13 cannot effectively obtain image information. Therefore, the first vision assembly 13 is arranged at the downstream end of the splicing platform 112, which facilitates the installation and debugging of the first vision assembly 13, and enables the first vision assembly 13 to effectively obtain image information.

[0085] In addition, in some examples, referring to FIG. 5, the die-cutting device 10 further comprises a reinforcing rib assembly 16, the reinforcing rib assembly 16 is located at the downstream end of the first vision assembly 13. At the same time, in order to reduce the investment of equipment and simplify the structure of the die-cutting device 10, the reinforcing rib assembly 16 can be one.

[0086] In this way, by arranging the first vision assembly 13 at the downstream end of the splicing platform 112, the first vision assembly 13 can simultaneously detect the incoming material quality and the splicing quality, so that the material 300 can be stably die-cut, thereby improving the production yield of the material 300.

[0087] According to some embodiments of the present application, referring to FIG. 5, the die-cutting device 10 further comprises a first tension assembly 12, the first tension assembly 12 is arranged in the first warehouse body 21 and used to tension the material 300 output by the feeding module 11.

[0088] The first tension assembly 12 refers to a device for tensioning the material 300, so that the material 300 is in a tension state during the transmission process. The first tension assembly 12 can be designed in a swing lever structure, and the tension force on the material 300 is changed by lifting or lowering the swing lever. Alternatively, the first tension assembly 12 can also be designed in a cam structure, and the tension force on the material 300 is changed by rotating the cam structure.

[0089] In addition, in order to make the winding module 15 stable, the winding module 15 can also include a winding assembly 151 and a second tension assembly 152, and the second tension assembly 152 is located at the upstream end of the winding assembly 151. The structure of the second tension assembly 152 can be consistent with that of the first tension assembly 12.

[0090] In this way, the material 300 output by the feeding module 11 is tensioned by the first tension assembly 12, so that the material 300 is stably transmitted between the feeding module 11 and the die cutting module 14, thereby making the die cutting operation stable.

[0091] According to some embodiments of the present application, referring to FIG. 5, the first tension assembly 12 includes a tension roller 121 and a magnetic powder clutch 122, and the tension roller 121 is used for the material 300 to be arranged around, and the magnetic powder clutch 122 is connected with the tension roller 121.

[0092] The magnetic powder clutch 122 refers to a mechanical element that uses the control of the magnetic field on the magnetic powder to realize the transmission adjustment. The output torque of the tension roller 121 can be controlled, so that the material 300 is in a tension state between the feeding module 11 and the die cutting module 14.

[0093] In this way, the magnetic powder clutch 122 is introduced, which facilitates effective control of the tension force of the material 300. At the same time, compared with the traditional swing lever structure, the structure is simple, and the tension force control is convenient.

[0094] According to some embodiments of the present application, referring to FIG. 1, the exhaust device 20 further includes a third warehouse body 23, and the third warehouse body 23 is provided with an exhaust assembly 24, and the die cutting module 14 is arranged in the third warehouse body 23.

[0095] The third warehouse body 23 refers to a structure with a certain space inside, which can accommodate the die cutting module 14, so as to achieve the purpose of partitioning the die cutting module 14. The die cutting module 14 is sealed separately, which facilitates the separate exhaust of the die cutting module 14, and is conducive to timely reducing the exhaust gas generated in the die cutting module 14.

[0096] To facilitate the transmission of the material 300 between the feeding module 11, the die-cutting module 14 and the winding module 15, the third warehouse body 23 can be located between the first warehouse body 21 and the second warehouse body 22. At the same time, the third warehouse body 23 can have a certain distance between the first warehouse body 21 and the second warehouse body 22, respectively, or can be connected with each other. In some examples, the first warehouse body 21, the third warehouse body 23 and the second warehouse body 22 are sequentially attached and connected with each other.

[0097] In this way, the die-cutting module 14 is arranged in the third warehouse body 23, which facilitates the reduction of the concentration of waste gas in the third warehouse body 23, effectively reduces the risk of contact between the operator and the waste gas during the production process, and realizes safe production.

[0098] According to some embodiments of the present application, referring to FIG. 1, the die-cutting module 14 includes a laser cutting mechanism 141 and a slitting knife mechanism 142, both of which are arranged in the third warehouse body 23.

[0099] The laser cutting mechanism 141 refers to a device that uses a laser beam to irradiate so that the material 300 reaches the melting point or boiling point to achieve the purpose of cutting, such as: taking battery die-cutting as an example, the laser cutting mechanism 141 can cut one side of the pole piece 200 to form a pole lug 230 of a desired shape; or it can also cut the connection between the pole piece 200 and the pole piece 200 to achieve the purpose of one out of many, etc.

[0100] The slitting knife mechanism 142 refers to a device that uses the cutting performance of a knife to slit the material 300 into a desired shape, which can be but is not limited to a disc-shaped knife, a square-shaped knife, etc.

[0101] In addition, the third warehouse body 23 can be designed to have a closed cavity structure, and the laser cutting mechanism 141 and the slitting knife mechanism 142 are arranged in the same cavity. Of course, the third warehouse body 23 can also be designed to have two independent closed space structures, so that the laser cutting mechanism 141 and the slitting knife mechanism 142 are arranged in different cavities.

[0102] In this way, the laser cutting mechanism 141 and the slitting knife mechanism 142 are introduced to provide different cutting methods for the die-cutting of the material 300 to meet the different die-cutting needs of the material 300, which is beneficial to improve the die-cutting effect.

[0103] According to some embodiments of the present application, referring to FIG. 1, the third housing 23 comprises a first sub-housing 231 and a second sub-housing 232 outside the first sub-housing 231, the laser cutting mechanism 141 is arranged in the first sub-housing 231, the slitting knife mechanism 142 is arranged in the second sub-housing 232, and the first sub-housing 231 and the second sub-housing 232 are both provided with the exhaust assembly 24.

[0104] The second sub-housing 232 is outside the first sub-housing 231, which means that the third housing 23 has two independent cavities. The laser cutting mechanism 141 is arranged in the first sub-housing 231, and the slitting knife mechanism 142 is arranged in the second sub-housing 232, so that they are separately sealed and provided with a separate working environment, reducing the possibility of mutual influence.

[0105] The first sub-housing 231 and the second sub-housing 232 can be spaced apart from each other or connected to each other. For example, the first sub-housing 231 and the second sub-housing 232 are connected to each other, and the internal space of the first sub-housing 231 and the internal space of the second sub-housing 232 are separated by a partition structure, that is, the first sub-housing 231 and the second sub-housing 232 share a partition structure.

[0106] When the laser cutting mechanism 141 and the slitting knife mechanism 142 are arranged in the first sub-housing 231 and the second sub-housing 232 respectively, the material 300 can extend out from the gap on the first sub-housing 231, then extend into the gap on the second sub-housing 232, and be installed on the slitting knife mechanism 142. Of course, openings for the material 300 to enter or exit can also be provided on the first sub-housing 231 and the second sub-housing 232 respectively.

[0107] During the die cutting process, the exhaust assembly 24 can exhaust the first sub-housing 231 and the second sub-housing 232 respectively, and timely reduce the concentration of waste gas in the first sub-housing 231 and the second sub-housing 232. The exhaust assembly 24 can include an inlet pipe 241 and an exhaust pipe 242, both of which are connected to the first sub-housing 231 and the second sub-housing 232.

[0108] In addition, in some examples, to detect the concentration of waste gas in the first sub-housing 231 and the second sub-housing 232, a detector 25 can be arranged in the first sub-housing 231 and the second sub-housing 232; at the same time, to obtain the internal and external pressure difference of the first sub-housing 231 and the second sub-housing 232, a pressure difference meter 26 can be arranged in the first sub-housing 231 and the second sub-housing 232.

[0109] In this way, the laser cutting mechanism 141 and the slitting knife mechanism 142 are arranged in the first sub-housing 231 and the second sub-housing 232 respectively, so that they are separately partitioned, the waste gas is separately exhausted, and the concentration of waste gas is effectively controlled below the set value.

[0110] According to some embodiments of the present application, referring to FIG. 5, the die-cutting module 14 further comprises a first collection box 143 for collecting the excess material generated by the laser cutting mechanism 141.

[0111] In the laser cutting, part of the excess material will be generated. If the excess material is accumulated in the first sub-warehouse 231, it will not only increase the difficulty of cleaning, but also affect the laser cutting effect in the process of pumping. Therefore, the first collection box 143 is provided to recycle the generated excess material. The shape of the first collection box 143 has various designs, such as but not limited to a cube, a cuboid, a cylinder, etc. Among them, the excess material refers to the particles or block materials of the material 300 falling in the die-cutting process.

[0112] In addition, in order to effectively collect the excess material generated by the slitting knife mechanism 142, a second collection box 144 can also be provided in the second sub-warehouse 232.

[0113] In this way, the first collection box 143 is introduced to collect the excess material generated by the laser cutting, which facilitates the recycling of the excess material and reduces the impact of the accumulated excess material on the laser cutting, thereby improving the laser cutting effect.

[0114] According to some embodiments of the present application, referring to FIG. 5, the first collection box 143 comprises a box body 14c with a collection port 14e and a poking assembly 14d at least partially arranged in the box body 14c and used for poking the excess material below the collection port 14e.

[0115] The poking assembly 14d refers to a mechanical structure that can scatter the excess material in the first collection box 143. When a large amount of excess material is accumulated at the collection port 14e, the newly generated excess material cannot continue to fall into the first collection box 143, resulting in the excess material overflowing and scattering out. At this time, the poking assembly 14d can be used to poke the excess material below the collection port 14e to reduce the accumulation of the excess material below the collection port 14e.

[0116] In order to realize automatic material poking, a material level sensor can be provided at the collection port 14e of the first collection box 143. When the material level at the collection port 14e reaches a threshold, the material level sensor sends the material level information to the control system. The control system then controls the action of the poking assembly 14d to poke the excess material. Among them, the structure of the poking assembly 14d has various designs, such as: the poking assembly 14d can include a motor and a poking rod, the motor drives the poking rod to rotate to poke the excess material below the collection port 14e; or it can also include a cylinder and a push plate, the cylinder drives the push plate to move back and forth to push the excess material, etc.

[0117] In this way, by rotating the rotating assembly 14d, the excess material under the collecting opening 14e can be rotated in time, so as to reduce the accumulation of the excess material and realize sustainable automatic collection of the excess material.

[0118] According to some embodiments of the present application, referring to FIGS. 6 and 7, the laser cutting mechanism 141 includes a first laser cutting assembly 14a and a second laser cutting assembly 14b.

The preset direction Y intersects the conveying direction X of the material 300.

[0119] The first laser cutting assembly 14a cuts the first side of the material 300, so that the first side of the material 300 is processed into a desired shape. For example, in the die cutting of the pole piece 200, the first laser cutting assembly 14a cuts the blank area 220 of the pole piece 200, so that the blank area 220 forms a plurality of spaced apart pole ears 230.

[0120] The second laser cutting assembly 14b and the slitting knife mechanism 142 are both configured to cut the second side of the material 300, but they are activated alternatively. For example, when the second laser cutting assembly 14b is in a working state, the slitting knife mechanism 142 is in a stop working state. When the slitting knife mechanism 142 is in a working state, the second laser cutting assembly 14b is in a stop working state. In the die cutting of the pole piece 200, the second laser cutting assembly 14b and the slitting knife mechanism 142 can both cut a blank area 220 of the pole piece 200. For example, the blank area 220 of the pole piece 200 can be cut along the conveying direction X to achieve the purpose of one-out-multiple.

[0121] In this way, the first laser cutting assembly 14a and the second laser cutting assembly 14b are introduced to meet the cutting requirements of different sides of the material 300 and improve the die cutting effect.

[0122] According to some embodiments of the present application, referring to FIG. 5, the die cutting module 14 further includes a cleaning assembly 145. The cleaning assembly 145 is located between the laser cutting mechanism 141 and the slitting knife mechanism 142 along the conveying direction X of the material 300, and is configured to clean the material 300.

[0123] The cleaning assembly 145 refers to a device capable of cleaning the surface of the material 300. The cleaning assembly 145 can be a brush structure or a wind knife structure. In some examples, the cleaning assembly 145 includes a first wind knife component 14f and a second wind knife component 14g. The first wind knife component 14f and the second wind knife component 14g are sequentially distributed along the conveying direction X, and both of them blow air to the two surfaces of the material 300 along the thickness direction of the material 300, respectively.

[0124] In this way, the surface of the material 300 is cleaned by the cleaning assembly 145, the cutting debris on the surface is reduced, and the probability of defects such as pits on the surface of the material 300 caused by the adhered debris is reduced.

[0125] According to some embodiments of the present application, referring to FIG. 5, the die-cutting module 14 further comprises a second vision assembly 146 located between the laser cutting mechanism 141 and the slitting knife mechanism 142 along the conveying direction X of the material 300, for detecting the appearance of the material 300 before entering the slitting knife mechanism 142.

[0126] The second vision assembly 146 refers to a device capable of obtaining image information of the appearance of the material 300, such as but not limited to a CCD (charge coupled device) camera, etc. The second vision assembly 146 is arranged at the upstream end of the slitting knife mechanism 142 for detecting the material 300 before slitting. In some examples, the winding module 15 can further comprise a third vision assembly 153 located at the upstream end of the winding assembly 151.

[0127] In this way, the second vision assembly 146 is introduced to detect the appearance of the material 300 before slitting, so that the material 300 with defects is stopped in front of the slitting knife mechanism 142, the number of unqualified products is reduced, and the yield of production is improved.
