[0003] The present application relates to the technical field of battery preparation, and in particular to a leader device, processing equipment and a battery production system. Background Art

[0004] During the battery production process, the pole pieces need to go through multiple processes, such as coating, cold pressing, die-cutting, winding, etc. During the above processes, the pole pieces are prone to breakage.

[0005] In the related art, after the pole piece breaks, the broken pole piece is generally wound and fixed on a circular traction rod, and then the circular traction rod is driven forward to realize the function of leading the belt.

[0006] However, the above method has the following defects: it requires two people to work together to wind the electrode and fix it on the circular traction rod. The operation is cumbersome, inconvenient, time-consuming and labor-intensive. It is impossible to quickly guide the broken electrode, which reduces the processing efficiency of the electrode and directly affects the production efficiency of the battery.

[0007] Summary of the Invention

[0008] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides a lead-in device, processing equipment, and battery production system with a simple structure that can efficiently lead broken pole pieces, thereby improving the processing efficiency of the pole pieces and also improving the production efficiency of the battery.

[0009] In a first aspect, the present application provides a leader device, comprising:

[0010] The guide piece is provided with a flat connecting portion for the end portion of the strip to be attached and connected;

[0011] The driving mechanism is connected to the guide member to drive the guide member to move the strip.

[0012] The leader device according to the first aspect of the present application has at least the following beneficial effects:

[0013] The guide device of the present application is provided with a guide member and a flat connecting portion on the guide member. When the strip breaks during processing, the operator can directly stick the end of the strip where the break is located on the flat connecting portion by gluing or double-sided tape to achieve flat connection and fixation of the end of the strip with the guide member, thereby realizing the strip splicing operation. Then, under the driving action of the driving mechanism, the guide member can drive the strip to move to transport the strip to the next processing station.

[0014] Compared with the existing method of leading the strip by the collaborative operation of two operators and the use of a winding and fixing method to wrap and fix the strip on a circular traction rod, the leading device of the present application, by providing a guide and a flat connecting part on the guide, only requires one operator to operate and use a flat laying method to quickly connect and fix the broken strip on the guide. The operation is simple, which not only increases the connection area between the strip and the guide and improves the connection stability between the strip and the guide, but also realizes efficient leading of the broken strip, thereby improving the processing efficiency of the strip and also improving the production efficiency of the battery.

[0015] In some embodiments, the guide member is provided with a first chamfered contact portion on one side in the length direction of the planar connection portion, and the first chamfered contact portion and the planar connection portion have a height difference in the thickness direction of the guide member.

[0016] In this way, the first chamfered contact portion will release the stretching of the strip at the turning point, reducing or even eliminating the stretching length of the side of the corresponding planar connection portion of the strip during the turning process, thereby reducing the risk of the strip being pulled and broken during the turning movement of the guide member, and improving the stability and safety of the strip movement.

[0017] In some embodiments, the guide member is provided with a second chamfered contact portion on the other side of the planar connection portion in the length direction, and the second chamfered contact portion and the planar connection portion have a height difference in the thickness direction of the guide member.

[0018] In this way, the first chamfered contact portion and the second chamfered contact portion will simultaneously release the stretching of the strip at the turning point, further reducing or even eliminating the stretching length of the two sides of the corresponding planar connection portion of the strip during the turning process, thereby reducing the risk of the strip being pulled and broken during the turning movement of the guide member, and further improving the stability and safety of the strip movement.

[0019] In some embodiments, there are multiple guide members along the moving direction of the strip, and two adjacent guide members are arranged at intervals;

[0020] Alternatively, there are a plurality of guide members along the moving direction of the strip, and two adjacent guide members are hinged.

[0021] This increases the connection area between the strip and the guide, improving the connection stability between the strip and the guide. At the same time, it can avoid interference between adjacent guides during the diversion process of the strip driven by all guides, thereby improving the smoothness of the strip's diversion movement.

[0022] In some embodiments, the guide is configured as a sheet-like structure, and a thickness of the guide is less than a thickness of the strip.

[0023] In this way, the thickness of the guide is reduced, the risk of the strip colliding with structural components on the processing equipment when entering the processing equipment is reduced, and the stability and safety of the guide in driving the strip to move are improved.

[0024] In some embodiments, the driving mechanism includes a first rotating wheel and a traction belt wrapped around the first rotating wheel and extending along the moving direction of the strip, the guide is detachably connected to the traction belt, and the first rotating wheel can drive the traction belt to move along the moving direction of the strip.

[0025] In this way, by cooperating with the first rotating wheel and the traction belt, the first rotating wheel rotates around its own axis to drive the traction belt to move along the moving direction of the strip, thereby traction and conveying the strip to the processing station through the guide.

[0026] In some embodiments, the drive mechanism further comprises an adjustment wheel drivingly connected to the first rotating wheel.

[0027] In this way, it is convenient for the operator to manually turn the adjusting wheel, so that the operator can control the movement and stop of the strip in real time to meet the on-site processing needs of the strip.

[0028] In some embodiments, the leading device further includes a power-assisting mechanism, which can apply a driving force to the traction belt along the moving direction of the strip and can control the magnitude of the driving force.

[0029] In this way, the setting of the power assist mechanism saves driving force for the operator to manually turn the adjusting wheel, and also meets the control requirements of the operator to control the movement and stop of the strip by manually turning the adjusting wheel, meets the on-site processing control requirements of the strip, and has good adaptability.

[0030] In some embodiments, the power assist mechanism includes a second rotating wheel and a torque outputter transmission-connected to the second rotating wheel, and the traction belt is wound around the second rotating wheel.

[0031] In this way, the torque output device can limit the upper limit of the torque transmitted to the second rotating wheel, thereby preventing the traction belt from slipping due to excessive torque output by the torque output device, and further improving the stability and safety of the belt movement.

[0032] In some embodiments, the leading device further comprises a frame having a conveying space for the strip to move, and the guide is disposed in the conveying space.

[0033] In this way, the drive mechanism and the guide are easily assembled and disassembled, and at the same time, a sufficiently large moving space can be provided for the guide and the strip, which is conducive to smoothly conveying the strip to the processing station.

[0034] In a second aspect, an embodiment of the present application provides a processing device, which includes the above-mentioned leading device.

[0035] The processing equipment according to the second aspect of the present application has at least the following beneficial effects:

[0036] The processing equipment of the present application, since it is equipped with the above-mentioned leading device, also has the same technical effect brought by the above-mentioned leading device, that is, only one operator is required to operate, and the broken strip can be quickly connected and fixed on the guide in a flat laying manner. The operation is simple, which not only increases the connection area between the strip and the guide, and improves the connection stability between the strip and the guide, but also realizes efficient leading of the broken strip, thereby improving the processing efficiency of the strip and also improving the production efficiency of the battery.

[0037] In a third aspect, an embodiment of the present application provides a battery production system, which includes the above-mentioned processing equipment.

[0038] The battery production system of the present application, since it is equipped with the above-mentioned processing equipment, also has the same technical effects brought by the above-mentioned processing equipment, that is, only one operator is required to operate, and the broken pole piece can be quickly connected and fixed on the guide piece by flat laying. The operation is simple, which not only increases the connection area between the pole piece and the guide piece, and improves the connection stability between the pole piece and the guide piece, but also realizes efficient guiding of the broken pole piece, thereby improving the processing efficiency of the pole piece and also improving the production efficiency of the battery.

[0059] During the battery production process, the pole pieces need to go through multiple processes, such as coating, cold pressing, die-cutting, winding, etc. During the above processes, the pole pieces are prone to breakage.

[0060] In the related art, after the pole piece breaks, the broken pole piece is generally wound and fixed on a circular traction rod, and then the circular traction rod is driven forward to realize the function of leading the belt.

[0061] However, the above method has the following defects: it requires two people to work together to wind the electrode and fix it on the circular traction rod. The operation is cumbersome, inconvenient, time-consuming and labor-intensive. It is impossible to quickly guide the broken electrode, which reduces the processing efficiency of the electrode and directly affects the production efficiency of the battery.

[0062] To address the problem that existing devices make it cumbersome and inconvenient to re-thread a broken electrode, which reduces electrode processing efficiency and battery production efficiency, the present application provides a threading device, referring to Figures 1, 2, and 3. The threading device includes a guide 200 and a drive mechanism 300. The guide 200 is provided with a planar connection portion 210 for attaching and connecting the end of the strip 500. The drive mechanism 300 is connected to the guide 200 to drive the guide 200 to move the strip 500.

[0063] It should be noted that the strip 500 includes but is not limited to structures such as a pole piece, a diaphragm, and a material strip. The embodiment of the present application is described using the strip 500 as an example of a pole piece.

[0064] The tape leader of the present application can be assembled on processing equipment for processing the tape 500 , such as coating equipment, cold pressing equipment, drying equipment, die-cutting equipment, and winding equipment.

[0065] It should be noted that the planar connecting portion 210 on the guide 200 is a flat surface that matches the upper or lower surface of the strip 500. When the strip 500 breaks during processing, the operator can first cut the broken strip 500 at the fracture, and then attach the end of the strip 500 at the fracture to the planar connecting portion 210 of the guide 200 using adhesive or double-sided tape, thereby achieving a planar connection between the end of the strip 500 and the guide 200. It should be understood that the width of the planar connecting portion 210 on the guide 200 is greater than the width of the strip 500, ensuring that the end of the strip 500 can be fully attached to the planar connecting portion 210 on the guide 200, thereby increasing the connection area between the strip 500 and the guide 200 and improving the stability of the connection between the strip 500 and the guide 200.

[0066] A layer of glue or double-sided tape for bonding the end of the strip 500 can be laid flat on the planar connection portion 210 of the guide 200. Of course, a layer of glue or double-sided tape can also be applied to the lower surface of the end of the strip 500, so that the end of the strip 500 is adhered and fixed to the planar connection portion 210 of the guide 200.

[0067] The drive mechanism 300 is connected to the guide member 200. The end of the strip 500 is attached to the planar connection portion 210 of the guide member 200. Driven by the drive mechanism 300, the guide member 200 moves the strip 500. The movement direction X of the strip 500 can be a single straight line trajectory, a single curved trajectory, or a combination of straight and curved trajectories, without limitation. The movement direction X of the strip 500 shown in Figure 1 is a single straight line trajectory.

[0068] It is not difficult to understand that the leading device of the present application is provided with a guide 200 and a planar connecting portion 210 on the guide 200. When the strip 500 breaks during processing, the operator can directly attach the end of the strip 500 where the break is located to the planar connecting portion 210 by means of adhesive coating or double-sided tape, so as to realize the planar connection and fixation of the end of the strip 500 to the guide 200, thereby realizing the splicing operation of the strip 500. Then, under the driving action of the driving mechanism 300, the guide 200 can drive the strip 500 to move so as to transport the strip 500 to the next processing station.

[0069] Compared with the existing method of achieving leading by two operators working together and winding and fixing the strip on a circular traction rod, the leading device of the present application, by providing a guide 200 and a planar connecting portion 210 on the guide 200, only requires one operator to operate and adopt a flat laying method to quickly connect and fix the broken strip 500 on the guide 200 in a planar manner. The operation is simple, which not only increases the connection area between the strip 500 and the guide 200 and improves the connection stability between the strip 500 and the guide 200, but also realizes efficient leading of the broken strip 500, thereby improving the processing efficiency of the strip 500 and the production efficiency of the battery.

[0070] It is not difficult to understand that in the present application, referring to Figures 4, 5 and 6, when the driving mechanism 300 drives the strip 500 to move along a composite trajectory of a straight track and a curved track by driving the guide 200, the guide 200 will drive the strip 500 attached to it to turn at the junction of the straight track and the curved track.

[0071] 4 and 6 , under the driving action of the driving mechanism 300 , the guide 200 drives the strip 500 thereon to first move along a straight trajectory, then turn downward to move along a curved trajectory, and then turn upward to move along a straight trajectory.

[0072] It can be understood that, referring to Figures 7 and 8, when the guide 200 drives the strip 500 thereon to turn at the junction of the straight track and the curved track, since the plane defined by the planar connection part 210 of the guide 200 is an extended flat surface, that is, the flat surface defined by the planar connection part 210 of the guide 200 cannot coincide with the curved surface at the turning point when turning, especially there will be a large gap between the two side parts of the planar connection part 210 in the length direction and the curved surface at the turning point. It can be understood that the two side parts of the planar connection part 210 in the length direction will be tilted relative to the curved surface at the turning point, and the strip 500 is in planar contact connection with the planar connection part 210 of the guide 200, which will cause the two side parts of the planar connection part 210 of the strip 500 corresponding to the planar connection part to be stretched to a certain length at the turning point, resulting in the risk of the strip 500 being stretched and broken.

[0073] As shown in Figures 7 and 8 , the dotted line trajectory S0 represents the curved trajectory at the turning point, which also corresponds to the ideal trajectory of the strip 500 at the turning point. The solid line trajectory S1 represents the stretching trajectory of the strip 500 at the turning point, corresponding to the two sides of the planar connecting portion 210. Clearly, the two sides of the strip 500 at the turning point, corresponding to the planar connecting portion 210, are stretched to a certain length, which poses a risk of breaking the strip 500.

[0074] Based on the above situation, in some embodiments of the present application, referring to Figures 4, 5 and 9, the guide member 200 is provided with a first chamfered contact portion 220 on one side of the length direction of the planar connection portion 210, and the first chamfered contact portion 220 and the planar connection portion 210 have a height difference in the thickness direction of the guide member 200.

[0075] In some examples, the first chamfered contact portion 220 is located on the right side of the planar connection portion 210 .

[0076] 5 and 9 , the guide member 200 has a sheet-like structure, the planar connecting portion 210 is a horizontal plane, the first chamfered contact portion 220 is an inclined plane, and the planar connecting portion 210 and the first chamfered contact portion 220 form the upper surface of the guide member 200 .

[0077] At this time, the first chamfered contact portion 220 is tilted downward relative to the planar connecting portion 210, forming an angle between the first chamfered contact portion 220 and the planar connecting portion 210. It will be understood that the horizontal plane defined by the planar connecting portion 210 and the inclined plane defined by the first chamfered contact portion 220 are not coplanar, and there is a height difference between the two in the thickness direction of the guide member 200.

[0078] For another example, the guide member 200 has a sheet-like structure, the planar connecting portion 210 is a horizontal plane, the first chamfered contact portion 220 is an arc plane, the planar connecting portion 210 and the first chamfered contact portion 220 are transitionally connected, and the planar connecting portion 210 and the first chamfered contact portion 220 also form the upper surface of the guide member 200.

[0079] At this point, the first chamfered contact portion 220 is curved downward relative to the planar connecting portion 210, and an angle is formed between the line connecting the two endpoints of the first chamfered contact portion 220 and the planar connecting portion 210. Similarly, the horizontal plane defined by the planar connecting portion 210 and the arc surface defined by the first chamfered contact portion 220 are not coplanar, and there is a height difference between the two in the thickness direction of the guide member 200.

[0080] It is not difficult to understand, referring to Figures 10 and 11, by providing a first chamfered contact portion 220 on one side of the planar connection portion 210 in the length direction of the guide 200, and making the first chamfered contact portion 220 and the planar connection portion 210 have a height difference in the thickness direction of the guide 200, when the guide 200 drives the strip 500 thereon to turn at the junction of the straight track and the curved track, the first chamfered contact portion 220 located on one side of the planar connection portion 210 in the length direction will be closer to the curved surface at the turning point, reducing or even eliminating the gap between the side of the planar connection portion 210 in the length direction and the curved surface at the turning point, effectively reducing or even eliminating the stretching length of the side of the planar connection portion 210 of the strip 500 corresponding to the planar connection portion 210 when turning.

[0081] That is, it can be understood that by providing a first chamfered contact portion 220 on one side of the guide 200 in the length direction of the planar connection portion 210, and making the first chamfered contact portion 220 and the planar connection portion 210 have a height difference in the thickness direction of the guide 200, the first chamfered contact portion 220 will release the stretching amount of the strip 500 at the turning point, thereby reducing or even eliminating the stretching length of the side of the planar connection portion 210 of the strip 500 corresponding to the planar connection portion 210 when turning, thereby reducing the risk of the strip 500 being pulled and broken during the turning movement of the guide 200, and improving the stability and safety of the movement of the strip 500.

[0082] 9 , 10 and 11 , the guide member 200 is provided with a second chamfered contact portion 230 on the other side of the planar connection portion 210 in the length direction. The second chamfered contact portion 230 and the planar connection portion 210 have a height difference in the thickness direction of the guide member 200 .

[0083] In some examples, the first chamfered contact portion 220 and the second chamfered contact portion 230 are respectively located on both sides of the length direction of the planar connecting portion 210 , and the first chamfered contact portion 220 and the second chamfered contact portion 230 are symmetrically distributed relative to the center line of the planar connecting portion 210 .

[0084] For example, referring to Figures 5 and 9, the guide member 200 has a sheet-like structure, the planar connecting portion 210 is a horizontal plane, the first chamfered contact portion 220 and the second chamfered contact portion 230 are both inclined planes, and the planar connecting portion 210 and the first chamfered contact portion 220 form the upper surface of the guide member 200. At this time, the upper surface contour of the guide member 200 is an isosceles trapezoidal shape.

[0085] 10 and 11 , the dotted line trajectory S0 in FIG11 is a schematic diagram of a curved trajectory at the turning point, which also corresponds to the ideal trajectory of the strip 500 at the turning point. Through the above description of the effect of the first chamfered contact portion 220, it can be understood that by arranging the first chamfered contact portion 220 and the second chamfered contact portion 230 on both sides of the length direction of the planar connection portion 210 of the guide member 200, and making the first chamfered contact portion 220 and the second chamfered contact portion 230 have a height difference with the planar connection portion 210 in the thickness direction of the guide member 200, when the guide member 200 drives the strip 500 thereon to turn at the junction of the straight trajectory and the curved trajectory, the first chamfered contact portion 220 and the second chamfered contact portion 230 on both sides of the length direction of the planar connection portion 210 will be closer to the curved surface at the turning point, reducing or even eliminating the gap between the two side parts of the planar connection portion 210 in the length direction and the curved surface at the turning point, effectively reducing or even eliminating the stretching length of the two side parts of the strip 500 corresponding to the planar connection portion 210 when turning.

[0086] That is, the first chamfered contact portion 220 and the second chamfered contact portion 230 will simultaneously release the stretching of the strip 500 at the turning point, thereby further reducing or even eliminating the stretching length of the two sides of the corresponding planar connection portion 210 of the strip 500 during the turning, thereby reducing the risk of the strip 500 being pulled and broken during the turning movement of the guide member 200, and further improving the stability and safety of the movement of the strip 500.

[0087] 2 and 9 , in some embodiments of the present application, there are multiple guide members 200 along the moving direction X of the strip 500 , and two adjacent guide members 200 are arranged at intervals.

[0088] In some examples, referring to FIG. 2 , along the moving direction X of the strip 500 , there are four guide members 200 . At the initial position, the planar connecting portions 210 on all the guide members 200 are on the same plane.

[0089] When the strip 500 breaks during the processing, the operator can directly stick the end of the strip 500 where the break is located on the flat connection part 210 of all the guide parts 200 by gluing or double-sided tape. In this way, the connection area between the strip 500 and the guide part 200 is increased, and the connection stability between the strip 500 and the guide part 200 is improved.

[0090] In addition, by spacing two adjacent guide members 200 so that there is a small gap between the two adjacent guide members 200, it is possible to avoid interference between the movement of the two adjacent guide members 200 during the turning process of the strip 500 driven by all guide members 200, thereby improving the smoothness of the turning movement of the strip 500.

[0091] Moreover, it can be understood that, on the basis of ensuring the stable connection between the strip 500 and the guide 200, the length of the guide 200 can be set to be smaller. After the end corresponding to the fracture of the strip 500 is fitted and connected with the planar connection parts 210 of all the guides 200, the distribution trajectory of all the planar connection parts 210 at the turning point can be closer to the curved surface at the turning point during the turning movement of the strip 500 following the guide 200. In this way, the risk of the strip 500 being pulled and broken during the turning movement following the guide 200 can be reduced, thereby further improving the stability and safety of the movement of the strip 500.

[0092] Of course, in other embodiments, there are multiple guide members 200 along the moving direction X of the strip 500 , and two adjacent guide members 200 are hinged.

[0093] For example, two adjacent guide members 200 are hinged by hinges. In this way, it is also possible to avoid interference between the movements of the two adjacent guide members 200 during the turning process of the strip 500 driven by all the guide members 200, thereby improving the smoothness of the turning movement of the strip 500.

[0094] In some embodiments of the present application, referring to FIG. 3 and FIG. 9 , the guide member 200 is configured as a sheet-like structure, and a thickness h2 of the guide member 200 is smaller than a thickness h1 of the strip 500 .

[0095] In some examples, the guide member 200 may be a metal sheet or a metal film with a relatively small thickness.

[0096] It should be noted that, under the driving action of the driving mechanism 300, the guide 200 drives the strip 500 to move, so as to transport the strip 500 to the next processing station, such as in the process of transporting the strip 500 to the cold pressing processing equipment, in order to enhance the safety of the strip 500 when entering the cold pressing processing equipment, referring to Figure 4, a protective structure 600 will be set at the position before the cold pressing processing equipment. The protective structure 600 can be an upper and lower duckbill plate structure, and there is a safety gap between the upper duckbill plate and the lower duckbill plate for the strip 500 to pass through. The safety gap is generally less than 30 mm.

[0097] Correspondingly, in order to adapt to the safety gap on the protective structure 600, the present application constructs the guide 200 into a sheet structure and makes the thickness h2 of the guide 200 smaller than the thickness h1 of the strip 500. On the basis that the corresponding end portion at the fracture of the strip 500 can be planarly fitted and connected to the planar connection portion 210 of the guide 200, the thickness h2 of the guide 200 is correspondingly reduced, so that the strip 500 can smoothly pass through the safety gap on the protective structure 600 under the drive of the guide 200, thereby reducing the risk of the strip 500 colliding with the structural components on the cold pressing equipment during the process of entering the cold pressing equipment, and improving the stability and safety of the guide 200 in driving the strip 500 to move.

[0098] Referring to Figures 1, 4 and 6, in some embodiments of the present application, the driving mechanism 300 includes a first rotating wheel 310 and a traction belt 320 wrapped around the first rotating wheel 310 and extending along the moving direction X of the strip 500. The guide member 200 is detachably connected to the traction belt 320, and the first rotating wheel 310 can drive the traction belt 320 to move along the moving direction X of the strip 500.

[0099] In some examples, the lead mechanism includes a frame 100, and may include two or more first rotating wheels 310, with at least two first rotating wheels 310 mounted at the front and rear ends of the frame 100. The first rotating wheels 310 include a rotating shaft rotatably mounted on the frame 100 and sprockets disposed at each end of the rotating shaft. The traction belt 320 is configured as a chain belt that meshes with the sprockets and is wound around the corresponding sprockets in a closed loop. The sprockets can be connected to a corresponding power source, which can be an electronic power component such as a motor or an electric motor, or a manually rotating component such as a hand crank.

[0100] Furthermore, in this embodiment, sockets may be provided on the end walls of some of the chain links, and a plug-in rod may extend from the end wall of the guide member 200. The guide member 200 is secured to the chain link by plugging the plug-in rod into the socket. Of course, in another embodiment, latches may be provided on the end walls of some of the chain links, and threaded holes may be provided in the end wall of the guide member 200, thereby threading the guide member 200 to the chain link. This facilitates the removal, assembly, and replacement of the guide member 200.

[0101] It can be understood that in the present application, by cooperating with the first rotating wheel 310 and the traction belt 320, the first rotating wheel 310 rotates around its own axis, thereby driving the traction belt 320 to move along the moving direction X of the strip 500, thereby pulling and transporting the strip 500 to the processing station through the guide 200.

[0102] Furthermore, referring to FIG. 4 and FIG. 6 , the driving mechanism 300 further includes an adjusting wheel 330 drivingly connected to the first rotating wheel 310 .

[0103] In some examples, the adjusting wheel 330 is configured as a hand-cranked wheel with a rotating handle installed on the adjusting wheel 330, allowing an operator to manually rotate the adjusting wheel 330 to convey the strip 500 to a specific location. Furthermore, by configuring the adjusting wheel 330 as a hand-cranked wheel, the operator can control the movement and stopping of the strip 500 in real time, meeting the processing requirements of the strip 500 on site.

[0104] In some embodiments of the present application, referring again to FIG. 4 and FIG. 6 , the lead assembly further includes a power assist mechanism 400 , which can apply a driving force to the traction belt 320 along the moving direction X of the strip 500 and can control the magnitude of the driving force.

[0105] In some examples, the assist mechanism 400 includes a second rotating wheel 410 and a torque outputter 420 drivingly connected to the second rotating wheel 410, and the traction belt 320 is wound around the second rotating wheel 410. The structure of the second rotating wheel 410 can be the same as that of the first rotating wheel 310, and will not be repeated here.

[0106] It is understood that the operation of the torque output 420 is controlled by a background program. The torque output 420 can be, but is not limited to, a combined transmission structure of a reducer and a magnetic powder clutch, a combined transmission structure of a reducer and a magnetic wheel, a combined transmission structure of a reducer and a mechanical clutch, etc.

[0107] It is easy to understand that the power assist mechanism 400 and the drive mechanism 300 operate independently of each other. The power of the drive mechanism 300 is the manual torque applied by the operator to the adjustment wheel 330, while the driving force applied by the power assist mechanism 400 to the traction belt 320 along the moving direction X of the strip 500 is the torque output by the torque output 420.

[0108] By providing independent drive mechanism 300 and power-assist mechanism 400, power-assist mechanism 400 can apply sufficient drive to traction belt 320, thereby driving traction belt 320 along the moving direction X of strip 500. Simultaneously, during this process, the operator can also manually rotate adjustment wheel 330 to achieve real-time control and braking of traction belt 320. Thus, the configuration of power-assist mechanism 400 allows the operator to manually rotate adjustment wheel 330, saving driving force while also satisfying the operator's need to control the movement and stopping of strip 500 by manually rotating adjustment wheel 330. This meets the on-site processing and control requirements for strip 500, and demonstrates excellent adaptability.

[0109] In addition, it should be noted that the torque outputter 420 can limit the upper limit of the torque transmitted to the second rotating wheel 410 to avoid excessive torque output by the torque outputter 420 causing the traction belt 320 to slip, further improving the stability and safety of the movement of the strip 500.

[0110] 1 , 4 and 6 , the belt guide assembly further includes a frame 100 . The frame 100 has a conveying space 110 for the belt 500 to move. The guide member 200 is disposed in the conveying space 110 .

[0111] It should be noted that the frame 100 can be a frame for strip processing equipment, such as coating equipment, cold pressing equipment, drying equipment, die-cutting equipment, winding equipment, and other processing equipment. The conveying space 110 of the frame 100 is used to allow the strip 500 to pass freely. The conveying space 110 can be closed, open, or semi-open, without specific limitation.

[0112] The present application sets up a frame 100 and a conveying space 110 on the frame 100 to facilitate the disassembly and assembly of the driving mechanism 300 and the guide member 200. At the same time, it can provide a sufficiently large moving space for the guide member 200 and the strip 500, which is conducive to smoothly conveying the strip 500 to the processing station.

[0113] In addition, the present application also provides a processing device, which includes the above-mentioned leading device.

[0114] It should be noted that the processing equipment includes but is not limited to coating equipment, cold pressing equipment, drying equipment, die-cutting equipment, winding equipment, etc. The processing equipment is used to perform pre-processing of battery electrodes during the battery production process.

[0115] It is not difficult to understand that the processing equipment of the present application, since it is equipped with the above-mentioned leading device, also has the same technical effect brought by the above-mentioned leading device, that is, only one operator is required to operate and adopt a flat laying method to quickly connect and fix the broken strip 500 on the guide 200. The operation is simple, which not only increases the connection area between the strip 500 and the guide 200, and improves the connection stability between the strip 500 and the guide 200, but also realizes efficient leading of the broken strip 500, thereby improving the processing efficiency of the strip 500 and the production efficiency of the battery.

[0116] In addition, the present application also provides a battery production system, which includes the above-mentioned processing equipment.

The operation is simple, which not only increases the connection area between the pole piece and the guide 200 and improves the connection stability between the pole piece and the guide 200, but also realizes efficient guiding of the broken pole piece, thereby improving the processing efficiency of the pole piece and also improving the production efficiency of the battery.

[0118] In some embodiments of the present application, referring to Figures 1 to 11 , the present application provides a leader device processing equipment and a battery production system. The leader device includes a frame 100, a guide 200, and a drive mechanism 300. The frame 100 has a conveying space 110 for the movement of the strip 500.

The drive mechanism 300 is connected to the guide 200 to drive the guide 200 to move the strip 500. The processing equipment is equipped with the above-mentioned leader device. The battery production system is equipped with the above-mentioned processing equipment.

[0119] The leading device, processing equipment and battery production system of the present application only require one operator to operate and adopt a flat laying method to quickly connect and fix the broken strip 500 on the guide 200. The operation is simple, which not only increases the connection area between the strip 500 and the guide 200, and improves the connection stability between the strip 500 and the guide 200, but also realizes efficient leading of the broken strip 500, thereby improving the processing efficiency of the strip 500 and the production efficiency of the battery.
