Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a drying device and a battery production line. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] In the battery manufacturing process, the electrode strip is one of the important components. In the process of preparing the strip, an oven device is needed to dry the strip, but the strip often breaks during drying. Most of the existing oven devices rely on workers to splice the strip inside the oven after the strip breaks, which has the problems of low splicing efficiency and safety risks. Utility Model Content

[0004] The present application provides a drying device and a battery production line to improve the efficiency and safety of tape splicing.

[0005] This application is achieved through the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a drying device, which includes an oven and a material belt traction mechanism, the oven having a drying area through which the material belt passes; the material belt traction mechanism is used to pull the broken material belt in the oven to the outside of the oven; the material belt traction mechanism includes a vehicle body and a clamping mechanism, the vehicle body is movably arranged in the drying area, the clamping mechanism is arranged on the vehicle body, and the clamping mechanism is used to clamp and fix the material belt.

[0007] In the technical solution of the embodiment of the present application, a material belt traction mechanism is provided, and the material belt traction mechanism includes a vehicle body and a clamping mechanism. The clamping mechanism provides a clamping function, and the broken material belt can be clamped and fixed on the vehicle body, and the vehicle body is movable in the drying area. The vehicle body can be used to enter from one side of the drying area to pull the broken material belt out of the oven together, so that the staff can connect the material belt outside the oven. Compared with the prior art of connecting the material belt inside the oven, there is no need to stop the oven and wait for the oven to dissipate heat before manually putting on heat-insulating clothes to enter the oven to connect the material belt. The connecting time is shorter and the safety of connecting the material belt is higher, which correspondingly improves the connecting efficiency and safety of the material belt.

[0008] According to some embodiments of the present application, the clamping mechanism includes a pressure plate and a lower pressure piece, wherein the pressure plate is used to cooperate with the vehicle body to clamp the material strip; the lower pressure piece is used to apply pressure to the pressure plate so that the pressure plate can be close to the vehicle body to press the material strip.

[0009] In the above scheme, the material strip is clamped by cooperating with the pressure plate and the vehicle body. It is only necessary to control the lower pressure piece and adjust the pressure plate to be close to the vehicle body, so that the pressure plate and the vehicle body can be clamped on both sides of the thickness direction of the material strip. The structure is simple and the operation is more convenient.

[0010] According to some embodiments of the present application, the clamping mechanism further includes a guide portion, which is extended along the thickness direction of the material strip and is arranged on the vehicle body, and the guide portion is used for the pressure plate to pass through.

[0011] In the above scheme, a guide portion is provided on the vehicle body, and the pressure plate is passed through the guide portion. The guide portion can provide a guiding function for the movement of the pressure plate, so that the pressure plate can only move in the thickness direction of the material strip, allowing the pressure plate to better cooperate with the vehicle body to compress the material strip.

[0012] According to some embodiments of the present application, the pressing member is threadably matched with the guide portion.

[0013] In the above scheme, the lower pressing piece and the guide part are threadedly matched, and the guide part not only provides a guiding function for the lower pressing plate, but also provides a locking function of thread matching for the lower pressing piece. By rotating the lower pressing piece, the pressing plate can be pressed toward the side close to the vehicle body, thereby clamping and fixing the material strip, with a simple structure and convenient and quick operation.

[0014] According to some embodiments of the present application, the number of the guide portions is set to be multiple, and the multiple guide portions are located at both ends of the vehicle body in the width direction.

[0015] In the above scheme, multiple guide parts are distributed at both ends of the width direction of the vehicle body, and the guide parts are not easy to interfere with the material strip. In addition, the setting of multiple guide parts and the cooperation between the multiple guide parts can better provide guiding function for the pressure plate, so that the pressure plate can only move along the thickness direction of the material strip.

[0016] According to some embodiments of the present application, an anti-slip portion is provided on the side of the pressure plate facing the vehicle body.

[0017] In the above scheme, since the side of the pressure plate facing the vehicle body is in contact with the upper surface of the material strip, an anti-slip portion is provided on the side of the pressure plate facing the vehicle body. The anti-slip portion can increase the static friction between the pressure plate and the material strip, thereby improving the pressing stability of the pressure plate on the material strip and reducing the risk of relative movement or loosening between the pressure plate and the material strip.

[0018] According to some embodiments of the present application, the material belt traction mechanism further includes a driving mechanism, and the driving mechanism is used to drive the vehicle body to move along the conveying direction of the material belt.

[0019] In the above scheme, through the setting of the driving mechanism, the driving mechanism can drive the vehicle body through the drying area along the conveying direction of the material belt to pull the broken material belt out of the oven, without the need for manual force, which is more labor-saving and more convenient to operate.

[0020] According to some embodiments of the present application, the driving mechanism includes a traction rope and a driving assembly, the traction rope runs through the drying area along the conveying direction of the material belt, and the traction rope is used to connect to the vehicle body; the driving assembly includes a first reel, a second reel and a driving member, the first reel and the second reel are respectively located on both sides outside the oven, the two ends of the traction rope are respectively wound around the first reel and the second reel, and the driving member is used to drive the first reel and / or the second reel to rotate along their own axial direction.

[0021] In the above scheme, the driving mechanism is driven by a traction rope, the traction rope spans the drying area, the vehicle body is fixedly connected to the traction rope, and the traction rope is driven by the driving component to move along the conveying direction of the material belt, so that the vehicle body is moved from the feeding end side of the oven to the discharging end side of the oven after crossing the drying area. The driving component connects the two ends of the traction rope through the first reel and the second reel respectively. The first reel and the second reel are located outside the oven, and only the traction rope is spanned in the drying area, which reduces the space occupied by the driving component in the drying area and is more conducive to the spatial layout of the driving component. The driving member controls the rotation of the first reel or the second reel to realize the driving of the traction rope, which has a simple structure and is easy to implement.

[0022] According to some embodiments of the present application, the drying device includes a first drying component and a second drying component, the first drying component and the second drying component are arranged in the oven at intervals along the thickness direction of the material belt, and the gap between the first drying component and the second drying component forms a drying area through which the material belt passes. The first drying component includes an upper hull and a plurality of upper air nozzles, the plurality of upper air nozzles are distributed at intervals on the upper hull along the conveying direction of the material belt, and the upper air nozzle has a first air outlet; the second drying component includes a lower hull and a plurality of lower air nozzles, the plurality of lower air nozzles are distributed at intervals on the lower hull along the conveying direction of the material belt, and the lower air nozzle has a second air outlet.

[0023] In the above scheme, the first drying component and the second drying component are distributed in the oven along the thickness direction of the material belt, and a drying area for the material belt to pass through is formed between the first drying component and the second drying component. The first drying component and the second drying component can dry both sides of the material belt in the thickness direction respectively, and the drying effect is good. In addition, the first drying component includes an upper hull and a plurality of upper air nozzles, and the plurality of upper air nozzles are distributed on the upper hull at intervals along the conveying direction of the material belt. Hot air is discharged from the first air outlet of each upper air nozzle, so that the upper side of the material belt in the thickness direction can be dried at multiple points, and the drying range is wide and the drying effect is good. Similarly, the second drying component includes a lower hull and a plurality of lower air nozzles, and the plurality of lower air nozzles are distributed on the lower hull at intervals along the conveying direction of the material belt. Hot air is discharged from the second air outlet of each lower air nozzle, so that the lower side of the material belt in the thickness direction can be dried at multiple points, and the drying range is wide and the drying effect is good.

[0024] According to some embodiments of the present application, rollers are provided at the bottom of the vehicle body.

[0025] In the above solution, by arranging rollers at the bottom of the vehicle body, the rollers can reduce the friction resistance of the vehicle body passing through the drying area, which is more conducive to the vehicle body passing through the drying area more quickly and smoothly.

[0026] According to some embodiments of the present application, along the conveying direction of the material belt, each lower air nozzle is recessed at a position corresponding to the roller to form a track, and the track is used to cooperate with the roller in rolling.

[0027] In the above scheme, since the material supply belt passes through the drying area, the space in the drying area in the thickness direction of the material belt is limited. In order to allow the vehicle body to pass through the limited space, a track for the rollers of the vehicle body to run is opened in each lower air nozzle recess. In this way, the roller is located in the track. The track can not only provide a guiding function for the roller, but also absorb the space occupied by the roller in the thickness direction of the material belt, that is, it can reduce the space occupied by the vehicle body in the thickness direction of the material belt, reduce the risk of interference between the vehicle body and the material belt, and is more conducive to the vehicle body passing through the drying area smoothly.

[0028] According to some embodiments of the present application, each lower tuyere is recessed to form a clearance groove for the traction rope to pass through.

[0029] In the above scheme, a recessed groove is formed on the lower air nozzle, and the recessed groove allows the traction rope to pass through the oven along the conveying direction of the material belt. During the normal drying process of the material belt by the drying equipment, the traction rope passes through the recessed groove, and the material belt gives way, which reduces the risk of interference between the traction rope and the material belt. In this way, the traction rope and the driving assembly are arranged normally, and the vehicle body and the traction rope can be separated. When the material belt breaks, the vehicle body is connected to the traction rope to complete the traction of the material belt. The vehicle body can be used at any time, which is convenient and quick to use, and will not affect the normal drying operation of the material belt.

[0030] According to some embodiments of the present application, the driving mechanism further includes a roller group, which is rotatably disposed in the clearance groove, and the roller group is used for winding the traction rope to guide the movement of the traction rope.

[0031] In the above scheme, by arranging a roller group in the give way groove, the roller group can provide support and guiding functions for the traction rope, so that the traction rope can pass through the oven more smoothly along the conveying direction of the material belt, thereby improving the traction stability of the traction rope on the vehicle body.

[0032] According to some embodiments of the present application, the roller group includes a first roller and a second roller distributed along the conveying direction of the material belt, and the bottom surface of the first roller and the top surface of the second roller are in contact with the traction rope.

[0033] In the above scheme, the traction rope contacts the bottom surface of the first roller and the top surface of the second roller respectively. The first roller and the second roller cooperate to compress and guide the traction rope, so that the traction rope can always be located in the give way groove, reducing the risk of interference between the traction rope and the material belt.

[0034] In a second aspect, an embodiment of the present application further provides a battery production line, which includes the drying equipment of any of the aforementioned embodiments.

[0035] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0062] At present, the electrode material strip is one of the important components in the battery manufacturing process. In the preparation process of the material strip, an oven device is needed to dry the material strip, but the material strip often breaks during drying. Most of the existing material strips that break rely on manual entry into the oven to splice the strips. However, before workers enter the oven, they need to stop the oven to dissipate heat, and then put on heat-insulating clothes to enter the oven. Splicing the strips inside the oven has the problems of low splicing efficiency and safety risks.

[0063] Based on the above considerations, in order to improve the efficiency of splicing the material belt after it breaks, the present application designs a drying device, which includes an oven and a material belt traction mechanism. The oven has a drying area for the material belt to pass through; the material belt traction mechanism includes a vehicle body and a clamping mechanism. The vehicle body is movably arranged in the drying area, and the clamping mechanism is arranged on the vehicle body. The clamping mechanism is used to clamp and fix the material belt.

[0064] In such drying equipment, a clamping function is provided by a clamping mechanism, and the broken material strip can be clamped and fixed on the vehicle body, and then the broken material strip can be pulled out of the oven together by the vehicle body, so that the staff can connect the material strips outside the oven. There is no need to stop the oven and wait for the oven to dissipate heat before manually putting on heat-insulating clothes to enter the oven to connect the material strips. The connecting time is shorter and the connecting safety is higher, which also improves the connecting efficiency and safety of the material strips accordingly.

[0065] The present application embodiment provides a drying device, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a drying device in some embodiments of the present application; Figure 2 for Figure 1 A is an enlarged schematic diagram;

[0066] Figure 3The structure diagram of the material belt pulling mechanism of some embodiments of the present application. The drying equipment 100 includes an oven 10 and a material belt pulling mechanism 20. The oven 10 has a drying area 11 through which the material belt 200 passes. The material belt pulling mechanism 20 is used to pull the broken material belt 200 in the oven 10 to the outside of the oven 10. The material belt pulling mechanism 20 includes a vehicle body 21 and a clamping mechanism 22. The vehicle body 21 is movably arranged in the drying area 11. The clamping mechanism 22 is arranged on the vehicle body 21. The clamping mechanism 22 is used to clamp and fix the material belt 200.

[0067] The oven 10 is a box structure that provides a drying function for the feeding belt 200. Along the conveying direction X of the feeding belt 200, the two sides of the oven 10 are respectively a belt inlet 12 and a belt outlet 13. The belt 200 enters the drying area 11 from the belt inlet 12, and the belt 200 is output from the belt outlet 13 after passing through the drying area 11.

[0068] The material strip 200 may be a pole piece material strip, and the two sides of the material strip 200 in the thickness direction Z are respectively a first surface and a second surface, and the first surface and the second surface have an active material coating layer, and a drying device is required to dry the surface of the material strip 200 before winding to ensure the drying quality of the material strip 200. In other embodiments, the material strip 200 may also be a material strip 200 coated with an insulating layer or an adhesive layer.

[0069] The material belt traction mechanism 20 is a traction mechanism that provides traction for the broken material belt 200. The material belt traction mechanism 20 can be set separately from the oven 10. When the material belt 200 is broken, the material belt traction mechanism 20 is clamped and fixed with the material belt 200 by the clamping mechanism 22 on the vehicle body 21, and the material belt 200 and the broken end are passed through the material belt entrance 12 of the oven 10 and then pulled out from the material belt exit 13 of the oven 10 through the drying area 11, which is convenient for the staff to connect the belt outside. During the normal operation of the oven 10, the vehicle body 21 and the clamping mechanism 22 can be located outside the oven 10. The vehicle body 21 is a frame structure, which can be a frame.

[0070] like Figure 6 As shown, a tape splicing platform 50 is provided at the material tape outlet 13 of the oven 10 . The tape splicing platform 50 has a tape splicing pressure strip 51 . The staff completes the external tape splicing of the material tape 200 on the tape splicing platform 50 .

[0071] In the technical solution of the embodiment of the present application, a material belt traction mechanism 20 is provided, and the material belt traction mechanism 20 includes a vehicle body 21 and a clamping mechanism 22. The clamping mechanism 22 provides a clamping function, and can clamp and fix the broken material belt 200 on the vehicle body 21. The vehicle body 21 is movable in the drying area 11. The vehicle body 21 can be used to enter from one side of the drying area 11 to pull the broken material belt 200 together to the outside of the oven 10, so that the staff can connect the material belt 200 outside the oven 10. Compared with the prior art of connecting the material belt inside the oven 10, there is no need to stop the oven 10 and wait for the oven 10 to dissipate heat before manually putting on heat-insulating clothes to enter the oven to connect the material belt. The connecting time is shorter and the safety of connecting the material belt is higher, which correspondingly improves the connecting efficiency and safety of the material belt 200.

[0072] According to some embodiments of this application, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic structural diagram of a material belt traction mechanism according to some embodiments of the present application; Figure 4 for Figure 3 The clamping mechanism 22 includes a pressing plate 220 and a lower pressing member 221. The pressing plate 220 is used to cooperate with the vehicle body 21 to clamp the material strip 200. The lower pressing member 221 is used to apply pressure to the pressing plate 220 so that the pressing plate 220 can approach the vehicle body 21 to press the material strip 200.

[0073] The pressing plate 220 may be extended along the width direction Y of the vehicle body 21, that is, the pressing plate 220 is extended across the width direction Y of the material strip 200, that is, the pressing plate 220 is a whole plate across the width direction of the material strip. Of course, the pressing plate 220 may include two sub-pressing plates, which are respectively distributed on both sides of the width direction Y of the vehicle body 21, and the two sub-pressing plates are disconnected and have no connection relationship. The two sub-pressing plates are respectively pressed on both sides of the width direction of the material strip 200.

[0074] The pressing member 221 can be a variety of pressing members, for example, the pressing member 221 can be a pressing cylinder, the pressing member 221 can also be a magnet, or the pressing member 221 can also be a bolt structure. In the case where the pressing member 221 is a pressing cylinder, the pressing member 221 is arranged on one side of the width direction of the vehicle body 21, and the driving end of the pressing member 221 is connected to the pressing plate 220. The pressing member 221 drives the pressing plate 220 to approach or move away from the vehicle body 21. When the pressing plate 220 approaches the vehicle body 21, the material strip 200 is clamped or released. In the case where the pressing member 221 is a magnet, the vehicle body 21 can be a metal member, and the pressing member 221 is arranged on the pressing plate 220. The pressing plate 220 can be moved close to the vehicle body 21 by magnetic attraction to clamp on both sides of the thickness direction of the material strip 200. When the lower pressure piece 221 is a bolt structure, the bolt includes a screw and a nut. The screw is set on the vehicle body 21, and the pressure plate 220 is passed through the screw. The nut cooperates with the screw thread. By rotating the nut, the pressure plate 220 can be pressed toward one side of the vehicle body 21 to achieve clamping and fixing of the material strip 200.

[0075] The number of the clamping mechanisms 22 can be one group or multiple groups, and the multiple groups of clamping mechanisms 22 are spaced apart along the conveying direction of the material strip 200. In this embodiment, the number of the clamping mechanisms 22 is one group, the pressing plate 220 is arranged across the width direction of the material strip 200, and a pressing member 221 is correspondingly provided on both sides of the pressing plate 220, and the pressing member 221 applies a pressing force to both ends of the pressing plate 220.

[0076] The material strip 200 is clamped by cooperating with the pressure plate 220 and the vehicle body 21. It is only necessary to control the lower pressure piece 221 and adjust the pressure plate 220 to be close to the vehicle body 21, so that the pressure plate 220 and the vehicle body 21 can be clamped on both sides of the material strip 200 in the thickness direction. The structure is simple and the operation is more convenient.

[0077] Specifically, the material strip traction mechanism 20 is placed under the material strip 200 from the side of the material strip inlet 12 of the oven 10, the top surface of the car body 21 contacts the first surface of the material strip 200 in the thickness direction, and then the pressing plate 220 is pressed against the second surface of the electrode in the thickness direction under the action of the lower pressing member 221 to achieve clamping and fixing of the material strip 200.

[0078] According to some embodiments of this application, please continue to refer to Figure 4 The clamping mechanism 22 further includes a guide portion 222 , which is extended along the thickness direction Z of the material strip 200 and is disposed on the vehicle body 21 , and the guide portion 222 is used for the pressure plate 220 to pass through.

[0079] The guide portion 222 refers to a guide structure extending along the thickness direction Z of the material strip 200 and arranged on the vehicle body 21. The guide portion 222 provides a guiding function for the pressing plate 220. The guide portion 222 may be a guide column or a guide screw.

[0080] By providing a guide portion 222 on the vehicle body 21, the pressure plate 220 is inserted into the guide portion 222. The guide portion 222 can provide a guiding function for the movement of the pressure plate 220, so that the pressure plate 220 can only move in the thickness direction of the material strip 200, allowing the pressure plate 220 to better cooperate with the vehicle body 21 to press the material strip 200.

[0081] According to some embodiments of the present application, the pressing member 221 is threadably matched with the guide portion 222 .

[0082] The pressing member 221 refers to a nut structure that is threadedly matched with the guide portion 222. In this embodiment, the guide portion 222 is a screw, and the pressing member 221 is a locking nut. By rotating the pressing member 221, the pressing member 221 moves relative to the extending direction of the guide portion 222, and the nut is pressed against the side of the pressing plate 220 away from the vehicle body 21, providing a pressing force to the pressing plate 220, so that the pressing plate 220 and the vehicle body 21 are respectively clamped on both sides of the thickness direction of the material strip 200.

[0083] The lower pressing piece 221 is threadedly matched with the guide part 222, and the guide part 222 provides both a guiding function for the lower pressing plate 220 and a locking function of threaded matching for the lower pressing piece 221. By rotating the lower pressing piece 221, the pressing plate 220 can be pressed toward the side close to the vehicle body 21, thereby clamping and fixing the material strip 200, with a simple structure and convenient and quick operation.

[0084] According to some embodiments of this application, please refer to Figure 4 The number of the guide portions 222 is set to be multiple, and the multiple guide portions 222 are located at both ends of the vehicle body 21 in the width direction.

[0085] The number of the guide parts 222 can be two, and the two guide parts 222 are respectively located at the two ends of the width direction of the vehicle body 21. The two guide parts 222 cooperate with the pressure plate 220 to guide the pressure plate 220 so that the pressure plate 220 can only move along the thickness direction of the material strip 200, thereby realizing that the pressure plate 220 is close to or away from the vehicle body 21.

[0086] Multiple guide parts 222 are distributed at both ends of the vehicle body 21 in the width direction. The guide parts 222 are not easy to interfere with the material strip 200. In addition, the setting of multiple guide parts 222 and the cooperation between the multiple guide parts 222 can better provide guiding function for the pressure plate 220, so that the pressure plate 220 can only move along the thickness direction of the material strip 200.

[0087] According to some embodiments of the present application, a non-slip portion is provided on the side of the pressure plate 220 facing the vehicle body 21 .

[0088] The anti-skid portion refers to an anti-skid structure distributed on the surface of the side of the pressure plate 220 close to the vehicle body 21 and having an anti-skid function. The anti-skid portion can be a variety of anti-skid structures, for example, the anti-skid portion can be an anti-skid pattern or an anti-skid convex point structure. In this embodiment, the anti-skid portion includes a plurality of anti-skid convex points, and the plurality of anti-skid convex points are distributed in an array on the surface of the pressure plate 220 close to the vehicle body 21.

[0089] Since the side of the pressure plate 220 facing the vehicle body 21 is in contact with the upper surface of the material strip 200, an anti-slip portion is provided on the side of the pressure plate 220 facing the vehicle body 21. The anti-slip portion can increase the static friction between the pressure plate 220 and the material strip 200, thereby improving the clamping stability of the pressure plate 220 on the material strip 200 and reducing the risk of relative movement or loosening between the pressure plate 220 and the material strip 200.

[0090] According to some embodiments of this application, please refer to Figure 6 and Figure 7 , Figure 6 for Figure 1 A front view of the drying equipment in FIG. Figure 7 for Figure 1 The material belt traction mechanism 20 further includes a driving mechanism 23, and the driving mechanism 23 is used to drive the vehicle body 21 to move along the conveying direction X of the material belt 200.

[0091] The vehicle body 21 can be driven in a variety of ways to move in the drying area 11, either manually or by a driving mechanism 23. For example, the vehicle body 21 can be driven by manually pulling a rod, one end of which is connected to the vehicle body 21, and the other end of the rod is manually pulled to drive the vehicle body 21 to move, thereby pulling the broken material strip 200 out of the drying oven 10. Of course, the driving mechanism 23 can also be used to drive the vehicle body 21 to move.

[0092] The driving mechanism 23 can be a variety of driving structures. For example, the driving mechanism 23 can be a power driving system 234 of the vehicle body 21 itself, that is, the vehicle body 21 has a power driving system 234, the power driving system 234 includes a driving motor, a reducer and a transmission shaft, and the bottom of the vehicle body 21 is equipped with rollers 210. The power driving system 234 drives the wheels to rotate through the transmission shaft, so as to realize the movement of the vehicle body 21 along the conveying direction of the material belt 200 to pass through the drying area 11. Of course, the driving mechanism 23 can also be an external driving mechanism 23, that is, the external driving mechanism 23 is arranged outside the vehicle body 21, providing traction function for the vehicle body 21, and can also realize the vehicle body 21 passing through the drying area 11.

[0093] By setting the driving mechanism 23, the driving mechanism 23 can drive the vehicle body 21 to pass through the drying area 11 along the conveying direction of the material belt 200, so as to pull the broken material belt 200 out of the oven 10, without manual force, more labor-saving and more convenient operation.

[0094] According to some embodiments of this application, please refer to Figure 6 and Figure 7 The driving mechanism 23 includes a traction rope 230 and a driving assembly. The traction rope 230 runs through the drying area 11 along the conveying direction of the material belt 200, and the traction rope 230 is used to be connected to the vehicle body 21; the driving assembly includes a first reel 231, a second reel 232 and a driving member. The first reel 231 and the second reel 232 are respectively located on both sides outside the oven 10, and the two ends of the traction rope 230 are respectively wound around the first reel 231 and the second reel 232. The driving member is used to drive the first reel 231 and / or the second reel 232 to rotate along their own axis direction.

[0095] The traction rope 230 refers to a rope structure that provides traction for the vehicle body 21. There are many ways to fix the traction rope 230 and the vehicle body 21. For example, the traction rope 230 has a lock, and the vehicle body 21 has a key chain that matches the lock. The key chain is inserted into the lock to complete the fixed connection between the vehicle body 21 and the traction rope 230. Of course, the vehicle body 21 can also be provided with an elastic clip, which can be clamped on the traction rope 230 to fix the traction rope 230 and the vehicle body 21. Please refer to Figure 5 A guide hook 211 for guiding the traction rope 230 may be provided at the bottom of the vehicle body 21 to provide a guiding function for the traction rope 230 .

[0096] The two ends of the traction rope 230 are respectively wound around the first reel 231 and the second reel 232, and are used to drive the traction rope 230 to move along the conveying direction of the material belt 200, so as to drive the vehicle body 21 to move. The first reel 231 and the second reel 232 are respectively installed at the material belt inlet 12 of the oven 10 and the two sides outside the material belt inlet 12. By driving the first reel 231 and / or the second reel 232 to rotate, the traction effect of the traction rope 230 can be achieved.

[0097] The driving mechanism 23 is driven by a traction rope 230, the traction rope 230 spans the drying area 11, the vehicle body 21 is fixedly connected to the traction rope 230, and the traction rope 230 is driven by the driving component to move along the conveying direction of the material belt 200, so that the vehicle body 21 crosses the drying area 11 from the feeding end side of the oven 10 to the discharging end side of the oven 10. The driving component connects the two ends of the traction rope 230 through the first reel 231 and the second reel 232 respectively. The first reel 231 and the second reel 232 are located outside the oven 10, and only the traction rope 230 spans the drying area 11, which reduces the space occupied by the driving component in the drying area 11, and is more conducive to the spatial layout of the driving component. The driving member controls the rotation of the first reel 231 or the second reel 232 to realize the driving of the traction rope 230, which has a simple structure and is easy to implement.

[0098] According to some embodiments of this application, please continue to refer to Figure 6 and Figure 7 The drying device 100 includes a first drying assembly 30 and a second drying assembly 40, which are arranged in the oven 10 at intervals along the thickness direction Z of the material belt 200, and the gap between the first drying assembly 30 and the second drying assembly 40 forms a drying area 11 through which the material belt 200 passes. The first drying assembly 30 includes an upper hull 31 and a plurality of upper air nozzles 32, which are distributed at intervals on the upper hull 31 along the conveying direction X of the material belt 200, and the upper air nozzles 32 have a first air outlet; the second drying assembly 40 includes a lower hull 41 and a plurality of lower air nozzles 42, which are distributed at intervals on the lower hull 41 along the conveying direction X of the material belt 200, and the lower air nozzles 42 have a second air outlet 420.

[0099] Along the conveying direction X of the material belt 200, the upper air nozzles 32 and the lower air nozzles 42 can be arranged opposite to each other or staggered. In this embodiment, each upper air nozzle 32 and each lower air nozzle 42 are staggered, and the gaps between each upper air nozzle 32 and each lower air nozzle 42 constitute the drying area 11 through which the material belt 200 passes.

[0100] The drying equipment 100 also includes a heating unit, which can use a heating wire to heat the air, or use high-temperature and high-pressure steam to heat the air. The heated air is transported to the upper hull 31 and / or the lower hull 41 through a fan, and each upper air nozzle 32 is communicated with the internal cavity of the upper hull 31, and each lower air nozzle 42 is communicated with the internal cavity of the lower hull 41, and then discharged from the first air outlet of the upper air nozzle 32 and the second air outlet 420 of the lower air nozzle 42.

[0101] The first drying assembly 30 and the second drying assembly 40 are distributed in the oven 10 along the thickness direction Z of the material belt 200. A drying area 11 through which the material belt 200 passes is formed between the first drying assembly 30 and the second drying assembly 40. The first drying assembly 30 and the second drying assembly 40 can dry both sides of the material belt 200 in the thickness direction, respectively, and the drying effect is good. In addition, the first drying assembly 30 includes an upper hull 31 and a plurality of upper air nozzles 32, and the plurality of upper air nozzles 32 are distributed at intervals on the upper hull 31 along the conveying direction of the material belt 200. Hot air is discharged from the first air outlet of each upper air nozzle 32, so that the upper side of the material belt 200 in the thickness direction can be dried at multiple points, with a wide drying range and good drying effect. Similarly, the second drying component 40 includes a lower hull 41 and a plurality of lower air nozzles 42. The plurality of lower air nozzles 42 are spaced apart on the lower hull 41 along the conveying direction of the material strip 200. Hot air is discharged from the second air outlet 420 of each lower air nozzle 42, thereby being able to dry multiple points on the lower side of the material strip 200 in the thickness direction, with a wide drying range and good drying effect.

[0102] According to some embodiments of the present application, a roller 210 is provided at the bottom of the vehicle body 21 .

[0103] The roller 210 refers to a running wheel for the vehicle body 21 to travel, and the roller 210 is rotatably mounted on the bottom of the vehicle body 21 through a roller 210 frame. The vehicle body 21 and the lower air nozzle 42 are in rolling cooperation, so that the vehicle body 21 passes through the drying area 11. The number of rollers 210 can be multiple, and the multiple rollers 210 are distributed on both sides of the width direction and / or length direction of the bottom of the vehicle body 21. In this embodiment, the number of rollers 210 is ten, and the ten rollers 210 are respectively divided into two groups of rollers 210, and the two groups of rollers 210 are respectively located on both sides of the width direction of the vehicle body 21, and each group of rollers 210 includes five rollers 210, and the five rollers 210 are distributed at intervals along the length direction of the vehicle body 21.

[0104] By arranging the roller 210 at the bottom of the vehicle body 21 , the roller 210 can reduce the friction resistance of the vehicle body 21 passing through the drying area 11 , which is more conducive to the vehicle body 21 passing through the drying area 11 more quickly and smoothly.

[0105] According to some embodiments of this application, please refer to Figure 2 Along the conveying direction of the material belt 200 , each lower air nozzle 42 is recessed at a position corresponding to the roller 210 to form a track 421 , and the track 421 is used for rolling cooperation with the roller 210 .

[0106] The track 421 refers to a groove structure opened on the lower air nozzle 42. When the rollers 210 are distributed on both sides of the width direction of the vehicle body 21, the lower air nozzle 42 is provided with two tracks 421. The two tracks 421 are provided on the left and right sides of the lower air nozzle 42, that is, on both sides along the width direction of the material belt 200.

[0107] Since the material supply belt 200 passes through the drying zone 11, the space in the thickness direction Z of the material belt 200 in the drying zone 11 is limited. In order to allow the vehicle body 21 to pass through the limited space, a track 421 for the roller 210 of the vehicle body 21 to run is opened in the recess of each lower air nozzle 42. In this way, the roller 210 is located in the track 421. The track 421 can not only provide a guiding function for the roller 210, but also absorb the space occupied by the roller 210 in the thickness direction Z of the material belt 200, that is, it can reduce the space occupied by the vehicle body 21 in the thickness direction of the material belt 200, thereby reducing the risk of interference between the vehicle body 21 and the material belt 200, and making it more conducive for the vehicle body 21 to pass through the drying zone 11 smoothly.

[0108] According to some embodiments of this application, please refer to Figure 8 and Fig. 9 , Figure 8 A cross-sectional view of a drying device according to some embodiments of the present application; Fig. 9 for Figure 8The enlarged schematic diagram of B. Each lower air nozzle 42 is recessed to form a clearance groove 422 for the traction rope 230 to pass through.

[0109] The clearance groove 422 refers to a groove structure opened on the lower air nozzle 42. Along the conveying direction of the material belt 200, the clearance grooves 422 between each lower air nozzle 42 constitute a space for the traction rope 230 to pass through. The clearance groove 422 may be in the shape of a rectangular groove, which passes through both sides of the lower air nozzle 42 along the conveying direction of the material belt 200. The traction rope 230 passes through the clearance groove 422, and the height of the traction rope 230 is lower than the height of the upper surface of the lower air nozzle 42. Along the width direction of the material belt 200, the clearance groove 422 is set in the middle position of the lower air nozzle 42, and the clearance groove 422 and the track 421 are staggered, that is, along the width direction of the material belt 200, the clearance groove 422 is located between the two tracks 421.

[0110] By forming a recessed groove 422 on the lower air nozzle 42, the groove 422 allows the traction rope 230 to pass through the oven 10 along the conveying direction of the material belt 200. During the normal drying process of the material belt 200 by the drying equipment, the traction rope 230 passes through the groove 422, and the material belt 200 gives way, reducing the risk of interference between the traction rope 230 and the material belt 200. In this way, the traction rope 230 and the driving assembly are arranged normally, and the vehicle body 21 can be separated from the traction rope 230. When the material belt 200 breaks, the vehicle body 21 is connected to the traction rope 230 to complete the traction of the material belt 200. The vehicle body 21 can be used at any time, which is convenient and quick to use and will not affect the normal drying operation of the material belt 200.

[0111] Specifically, during the drying process of the material belt 200 by the drying equipment, the traction rope 230 and the driving assembly in the material belt traction mechanism 20 can be arranged normally, the traction rope 230 passes through the clearance slots 422 of each lower air nozzle 42, the first reel 231 and the second reel 232 of the driving assembly are located on both sides of the oven 10, and the vehicle body 21 is separated from the traction rope 230 and placed outside the drying equipment. When the material belt 200 breaks, the vehicle body 21 is connected to the traction rope 230, the clamping mechanism 22 on the vehicle body 21 clamps the broken side of the material belt 200, and the driving assembly drives the traction rope 230 to pull the vehicle body 21 through the oven 10, and the broken material belt 200 is pulled out of the oven 10.

[0112] According to some embodiments of this application, please refer to Fig. 9 and Fig.10 , Fig. 9 for Figure 8 A magnified schematic diagram of B; Fig.10 for Fig. 9The driving mechanism 23 further comprises a roller group 233, which is rotatably arranged in the clearance groove 422, and the roller group 233 is used for the traction rope 230 to be wound around so as to guide the traction rope 230 to move.

[0113] The roller group 233 refers to a guide roller structure provided in the clearance groove 422 to provide guidance for the traction rope 230. The roller group 233 can make the traction rope 230 pass through the drying zone 11 in a directional manner.

[0114] By providing a roller group 233 in the clearance groove 422, the roller group 233 can provide support and guiding functions for the traction rope 230, so that the traction rope 230 can pass through the oven 10 more smoothly along the conveying direction of the material belt 200, thereby improving the traction stability of the traction rope 230 on the vehicle body 21.

[0115] According to some embodiments of the present application, the roller group includes a first roller 2330 and a second roller 2331 distributed along the conveying direction of the material belt 200 , and the bottom surface of the first roller 2330 and the top surface of the second roller 2331 are in contact with the traction rope 230 .

[0116] The first roller 2330 and the second roller 2331 are both rotatably mounted on the clearance groove 422 via bearings. Under the motion of the traction rope 230, the traction rope 230 provides power to guide the first roller 2330 and the second roller 2331 to rotate along their own axis direction, and the first roller 2330 and the second roller 2331 cooperate to provide a guiding function for the traction rope 230.

[0117] The traction rope 230 contacts the bottom surface of the first roller 2330 and the top surface of the second roller 2331 respectively. The first roller 2330 and the second roller 2331 cooperate to compress and guide the traction rope 230, so that the traction rope 230 can always be located in the yield groove 422, reducing the risk of interference between the traction rope 230 and the material belt 200.

[0118] An embodiment of the present application also provides a battery production line, which includes the drying equipment of any of the aforementioned embodiments.

[0119] The present application embodiment provides a drying device, please refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of a drying device in some embodiments of the present application; Figure 2 for Figure 1 A is an enlarged schematic diagram; Figure 3 This is a schematic structural diagram of a material belt traction mechanism according to some embodiments of the present application; Figure 4 for Figure 3 Schematic diagram of the structure in the middle BB direction; Figure 5 for Figure 3 Schematic diagram of the structure in the CC direction; Figure 6 for Figure 1 The front view of the drying device in FIG. The drying device includes an oven 10 and a material belt traction mechanism 20. The oven 10 has a drying area 11 through which the material belt 200 passes. A first drying component 30 and a second drying component 40 are arranged in the oven 10. The first drying component 30 and the second drying component 40 are arranged in the oven 10 at intervals along the thickness direction of the material belt 200. The gap between the first drying component 30 and the second drying component 40 forms the drying area 11 through which the material belt 200 passes. The first drying component 30 includes an upper hull 31 and a plurality of upper air nozzles 32. The plurality of upper air nozzles 32 are distributed in the upper hull 31 at intervals along the conveying direction of the material belt 200. The upper air nozzles 32 have a first air outlet. The second drying component 40 includes a lower hull 41 and a plurality of lower air nozzles 42. The plurality of lower air nozzles 42 are distributed in the lower hull 41 at intervals along the conveying direction of the material belt 200. The lower air nozzles 42 have a second air outlet 420. The material belt pulling mechanism 20 is used to pull the broken material belt 200 in the oven 10 out of the oven 10; the material belt pulling mechanism 20 includes a vehicle body 21, a clamping mechanism 22 and a driving mechanism 23. The vehicle body 21 is movably arranged in the drying area 11. The bottom of the vehicle body 21 is provided with a roller 210. The driving mechanism 23 is used to drive the vehicle body 21 to move along the conveying direction of the material belt 200. The clamping mechanism 22 is arranged on the vehicle body 21, and the clamping mechanism 22 is used to clamp and fix the material belt 200. The clamping mechanism 22 includes a pressing plate 220 and a lower pressing member 221. The pressing plate 220 is used to cooperate with the vehicle body 21 to clamp the material belt 200; the lower pressing member 221 is used to apply pressure to the pressing plate 220 so that the pressing plate 220 can approach the vehicle body 21 to press the material belt 200.

[0120] The first drying component 30 and the second drying component 40 are distributed in the oven 10 along the thickness direction of the material belt 200, and a drying area 11 through which the material belt 200 passes is formed between the first drying component 30 and the second drying component 40. The first drying component 30 and the second drying component 40 can dry both sides of the material belt 200 in the thickness direction respectively, and the drying effect is good. The material belt traction mechanism 20 includes a vehicle body 21 and a clamping mechanism 22. The clamping mechanism 22 provides a clamping function and can clamp and fix the broken material belt 200 on the vehicle body 21. The vehicle body 21 can be moved in the drying area 11 under the action of the driving mechanism 23. The vehicle body 21 can be used to enter from one side of the drying area 11 to pull the broken material belt 200 out of the oven 10, so that the staff can connect the material belt 200 outside the oven 10. Compared with the prior art of connecting the material belt inside the oven 10, there is no need to stop the oven and wait for the oven to dissipate heat before manually putting on heat-insulating clothes to enter the oven to connect the material belt. The connecting time is shorter and the connecting safety is higher, which correspondingly improves the connecting efficiency and safety of the material belt 200. The material strip 200 is clamped by cooperating with the pressure plate 220 and the vehicle body 21. It is only necessary to control the lower pressure piece 221 and adjust the pressure plate 220 to be close to the vehicle body 21, so that the pressure plate 220 and the vehicle body 21 can be clamped on both sides of the material strip 200 in the thickness direction. The structure is simple and the operation is more convenient.

[0121] In some embodiments, please refer to Figure 4 The clamping mechanism 22 further includes a guide portion 222, which is extended along the thickness direction of the material strip 200 and arranged on the vehicle body 21, and the guide portion 222 is used for the pressure plate 220 to pass through. The lower pressing piece 221 is threadedly matched with the guide portion 222.

[0122] The pressing plate 220 is inserted through the guide part 222, and the guide part 222 can provide a guiding function for the movement of the pressing plate 220, so that the pressing plate 220 can only move in the thickness direction of the material strip 200, so that the pressing plate 220 can better cooperate with the vehicle body 21 to press the material strip 200. The lower pressing piece 221 is threadedly matched with the guide part 222, and the guide part 222 not only provides a guiding function for the lower pressing plate 220, but also provides a locking function of thread matching for the lower pressing piece 221. By rotating the lower pressing piece 221, the pressing plate 220 can be pressed toward the side close to the vehicle body 21, thereby clamping and fixing the material strip 200, with a simple structure and convenient and quick operation.

[0123] In some embodiments, the driving mechanism 23 includes a traction rope 230 and a driving assembly. The traction rope 230 runs through the drying area 11 along the conveying direction of the material belt 200, and the traction rope 230 is used to connect with the vehicle body 21; the driving assembly includes a first reel 231, a second reel 232 and a driving member. The first reel 231 and the second reel 232 are respectively located on both sides outside the oven 10, and the two ends of the traction rope 230 are respectively wound around the first reel 231 and the second reel 232, and the driving member is used to drive the first reel 231 and / or the second reel 232 to rotate along their own axis direction. Along the conveying direction of the material belt 200, each lower air nozzle 42 is recessed at a position corresponding to the roller 210 to form a track 421, and the track 421 is used to roll with the roller 210. Each lower air nozzle 42 is recessed to form a clearance groove 422 for the traction rope 230 to pass through.

[0124] The traction rope 230 spans the drying area 11, and the vehicle body 21 is fixedly connected to the traction rope 230. The driving component drives the traction rope 230 to move along the conveying direction of the material belt 200, so that the vehicle body 21 crosses the drying area 11 from the feeding end side of the oven 10 to the discharging end side of the oven 10. The driving component connects the two ends of the traction rope 230 through the first reel 231 and the second reel 232 respectively. The first reel 231 and the second reel 232 are located outside the oven 10, and only the traction rope 230 is spanned in the drying area 11, which reduces the space occupied by the driving component in the drying area 11 and is more conducive to the spatial layout of the driving component. The driving member controls the rotation of the first reel 231 or the second reel 232 to realize the driving of the traction rope 230, which has a simple structure and is easy to implement. The roller 210 is located in the track 421. The track 421 can not only provide a guiding function for the roller 210, but also absorb the space occupied by the roller 210 in the thickness direction of the material belt 200, that is, it can reduce the space occupied by the vehicle body 21 in the thickness direction of the material belt 200, reduce the risk of interference between the vehicle body 21 and the material belt 200, and facilitate the vehicle body 21 to pass through the drying area 11 smoothly.

[0125] In addition, the clearance groove 422 allows the traction rope 230 to pass through the oven 10 along the conveying direction of the material belt 200. During the normal drying process of the material belt 200 by the drying equipment, the traction rope 230 passes through the clearance groove 422, and the material belt 200 gives way, reducing the risk of interference between the traction rope 230 and the material belt 200. In this way, the traction rope 230 and the driving assembly are arranged normally, and the vehicle body 21 can be separated from the traction rope 230. When the material belt 200 breaks, the vehicle body 21 is connected to the traction rope 230 to complete the traction of the material belt 200. The vehicle body 21 can be used at any time, which is convenient and quick to use and will not affect the normal drying operation of the material belt 200.

[0126] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
