TECHNICAL FIELD

[0001] The present application relates to the technical field of batteries, in particular to an oven and a battery manufacturing device. BACKGROUND

[0002] Energy saving and emission reduction is 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 energy saving and environmental protection advantages. For electric vehicles, battery technology is an important factor for their development.

[0003] In the battery manufacturing process, the coated pole piece needs to be dried in an oven to produce a pole piece with a specified thickness and uniform coating consistency. Therefore, the drying process plays a crucial role in the production of pole pieces. Due to problems such as die scraping, roller wrinkling, and broken belts during the coating process, the air nozzle of the oven is prone to having waste adhered. However, the existing ovens generally clean the air nozzle of the oven manually, which has the problem of low cleaning efficiency. CONTENT OF THE UTILITY MODEL

[0004] The present application provides an oven and a battery manufacturing device that can clean the air nozzle of the oven and improve the cleaning efficiency of the air nozzle.

[0005] The present application is achieved by the following technical solutions:

[0006] In a first aspect, the present application provides an oven, which includes an oven body, an air outlet mechanism, and a cleaning assembly. The oven body has a drying zone for taking away material from a feed belt. The air outlet mechanism is arranged on the oven body and includes an air nozzle for blowing air towards the drying zone. The air nozzle has an air outlet extending along a first direction. The cleaning assembly is movably arranged in the oven body along the first direction. When the cleaning assembly is in a first position, it is located on one side of the oven body in the first direction to be out of position with the feed belt of the drying zone. When the cleaning assembly is in a second position, it is located in the drying zone and in contact with the air nozzle to clean the air nozzle.

[0007] In the technical scheme of the embodiment of the present application, the air nozzle in the air outlet mechanism can blow hot air towards the drying area to dry the material belt passing through the drying area. The cleaning assembly is movably arranged in the oven body along the first direction and moves between the first position and the second position. When the cleaning assembly moves to the second position along the extension direction of the first air outlet on the air nozzle, the cleaning assembly contacts the air nozzle and cleans the waste adhered to the air nozzle, without the need for manual cleaning of the air nozzle, thereby improving the cleaning efficiency of the air nozzle. When the cleaning of the air nozzle is completed, the cleaning assembly moves to the first position, and the cleaning assembly is located on one side of the oven body along the first direction, and the cleaning assembly is dislocated from the material belt in the drying area. During the drying of the material belt, the cleaning assembly does not interfere with the material belt, and the oven can normally dry the material belt.

[0008] According to some embodiments of the present application, the oven further comprises a driving assembly arranged on the oven body, and the driving assembly is configured to drive the cleaning assembly to move along the first direction between the first position and the second position.

[0009] In the above scheme, the driving assembly can drive the cleaning assembly to move along the first direction, without the need for manual movement of the cleaning assembly, thereby saving labor and reducing the labor intensity of cleaning the air nozzle.

[0010] According to some embodiments of the present application, the air nozzle has a first surface facing the cleaning assembly, and the air outlet is located on the first surface; the cleaning assembly comprises a mounting base and a main scraper, the mounting base is connected with the driving assembly; the main scraper is arranged on the mounting base; and the main scraper is configured to contact the first surface of the air nozzle to scrape off the waste on the first surface of the air nozzle.

[0011] In the above scheme, the main scraper is arranged on the mounting base, and the main scraper is used to scrape off the waste adhered to the first surface of the air nozzle, thereby achieving the cleaning of the air nozzle and improving the cleaning effect of the air nozzle.

[0012] According to some embodiments of the present application, the number of main scrapers is two, and the two main scrapers are spaced apart on the mounting base along the first direction.

[0013] In the above scheme, the number of main scrapers is two, and the two main scrapers can cooperate with each other and are distributed on the mounting base along the first direction. The two main scrapers clean the first surface of the air nozzle in front and behind, which is equivalent to twice cleaning of the same area of the air nozzle by the two main scrapers, thereby improving the cleaning effect of the air nozzle.

[0014] According to some embodiments of the present application, the distance between the two main scrapers gradually increases from the side of the main scrapers close to the mounting substrate to the side of the main scrapers away from the mounting substrate.

[0015] In the above scheme, the distance between the two main scrapers gradually increases from the side of the main scrapers close to the mounting substrate to the side of the main scrapers away from the mounting substrate, that is, the two main scrapers are arranged in an eight-shaped manner on the mounting substrate. When the main scrapers scrape the waste on the first surface of the tuyere, the obliquely arranged scrapers can reduce the contact area with the first surface of the tuyere, thereby reducing the wear of the main scrapers and prolonging the service life of the main scrapers. Moreover, by reasonably setting the oblique angle of the main scrapers, compared with the vertical contact between the main scrapers and the first surface of the tuyere, the stress of the main scrapers in contact with the tuyere can be decomposed in the vertical direction and the horizontal direction under the condition of ensuring the scraping effect of the main scrapers, thereby reducing the pressure on the scrapers and the tuyere.

[0016] According to some embodiments of the present application, the cleaning assembly further comprises cleaning cotton, which is arranged on the mounting substrate and located between the two main scrapers. The cleaning cotton is used to contact the first surface of the tuyere to wipe and clean the first surface of the tuyere.

[0017] In the above scheme, by arranging the cleaning cotton, the cleaning cotton can contact the first surface of the tuyere to wipe and clean the waste adhered to the first surface of the tuyere. In the case of the main scrapers on the first surface of the tuyere, the main scrapers cooperate with the cleaning cotton to achieve better cleaning effect on the tuyere.

[0018] According to some embodiments of the present application, the cleaning assembly further comprises two side scrapers, which are arranged on the mounting substrate on two sides of the second direction respectively. The two side scrapers are respectively used to contact two sides of the second direction of the tuyere to scrape the waste on the two sides of the second direction of the tuyere. The second direction, the first direction and the vertical direction are perpendicular to each other.

[0019] In the above scheme, since the two sides of the second direction of the tuyere can be adhered with waste, by arranging the side scrapers in the cleaning assembly, the two side scrapers are located on the two sides of the second direction of the mounting substrate. During the movement of the cleaning assembly in the first direction, the two side scrapers can scrape and clean the two sides of the second direction of the tuyere to scrape the waste adhered to the two sides of the second direction of the tuyere. The cleaning range of the cleaning assembly on the tuyere is wider, and the cleaning effect of the cleaning assembly on the tuyere is better.

[0020] According to some embodiments of the present application, a collecting groove is arranged on the mounting substrate on the side of the main scrapers away from the cleaning cotton. The collecting groove is used to collect the waste scraped by the main scrapers and / or the side scrapers.

[0021] In the above scheme, by opening a collecting groove on the mounting substrate, the waste scraped by the main scraper and / or the side scraper can fall into the collecting groove, the collecting groove can collect the waste, avoid the waste scraped by the main scraper and the side scraper from being scattered everywhere, and improve the cleaning degree of the cleaning assembly on the oven.

[0022] According to some embodiments of the present application, the oven body has a first wall and a second wall relatively distributed in the vertical direction; the air outlet mechanism includes an upper hull and a lower hull, the upper hull and the lower hull are located at the first wall and the second wall of the oven body respectively, a plurality of tuyeres are alternately and spacedly distributed on the upper hull and the lower hull in a second direction, the area between the upper hull and the lower hull forms a drying zone through which the material belt passes, and the second direction is perpendicular to the first direction; the number of cleaning assemblies is set to be multiple, and the positions and numbers of the multiple cleaning assemblies correspond one-to-one to the positions and numbers of the multiple tuyeres.

[0023] In the above scheme, the multiple tuyeres are spacedly arranged on the upper hull and the lower hull in the second direction, the material belt passes through the drying zone in the second direction, and the tuyeres on the upper hull and the lower hull dry the two sides of the material belt respectively. By setting the number of cleaning assemblies to be multiple, the positions and numbers of the multiple cleaning assemblies correspond one-to-one to the positions and numbers of the multiple tuyeres, so that each tuyere is cleaned, manual cleaning of the tuyere is not needed, the cleaning efficiency of the tuyere is improved, and the cleaning effect is good.

[0024] According to some embodiments of the present application, the driving assembly includes a connecting frame and a driving member, the connecting frame is used to connect the multiple cleaning assemblies as a whole, and the driving member is arranged on the oven body and is used to drive the connecting frame to move in the first direction.

[0025] In the above scheme, by arranging the connecting frame, the connecting frame can connect the multiple cleaning assemblies as a whole, compared with that each cleaning assembly is equipped with a driving assembly, the number of driving assemblies is reduced, and the cost is lower. Moreover, the reduction of the number of driving assemblies also reduces the space occupied by the driving assemblies, which is more conducive to the spatial layout of the cleaning assemblies in the oven body.

[0026] According to some embodiments of the present application, the driving assembly further includes a guide portion, the guide portion is arranged on the oven body in the first direction, the connecting frame has a sliding portion that is in sliding cooperation with the guide portion, and the sliding portion is in sliding cooperation with the guide portion.

[0027] In the above scheme, by arranging the guide portion, the connecting frame has the sliding portion that is in sliding cooperation with the guide portion, the guide portion is in sliding cooperation with the sliding portion of the connecting frame, the connecting frame can be guided to move in the first direction, the stability and accuracy of the multiple cleaning assemblies during movement in the first direction are improved, and the cleaning effect on the tuyere is better.

[0028] According to some embodiments of the present application, the number of guide portions is multiple, and the multiple guide portions are respectively distributed on both sides of the second direction of the oven body.

[0029] In the above scheme, by respectively distributing the multiple guide portions on both sides of the second direction of the oven body, the guide portions are less likely to interfere with the tuyeres inside the oven body. Moreover, the multiple guide portions cooperate together, and multiple support points are provided between the connecting frame and the multiple guide portions, so that the stability of the connecting frame during movement is higher.

[0030] According to some embodiments of the present application, a height adjusting member is arranged between the connecting frame and the cleaning assembly, and the height adjusting member is used to adjust the position of the cleaning assembly in the vertical direction relative to the tuyere.

[0031] In the above scheme, in order to improve the fitting degree of the cleaning assembly and the tuyere, by arranging the height adjusting member between the connecting frame and the cleaning assembly, the height adjusting member can fine-tune the cleaning assembly in the vertical direction relative to the connecting frame, so that the cleaning assembly is better fitted with the corresponding tuyere, and the cleaning assembly can effectively clean the tuyere.

[0058] From the development of market situation, the application of power battery is more and more extensive. The power battery is not only applied to the energy storage power supply system of hydraulic, thermal, wind and solar power stations, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of power battery, the market demand is also increasing.

[0059] At present, the existing oven is generally manually cleaned by the air nozzle of the oven. The coating process is caused by problems such as die scraping, roller wrinkling or belt breaking, resulting in the air nozzle of the oven having slurry adhesion, causing the lug to have concave and convex points, pinholes, scratches, etc., affecting the production capacity and the yield. Generally, the staff uses dust-free paper and alcohol to manually clean the air nozzle of the oven. However, due to the small space inside the oven, the staff is limited when cleaning, and the inside roller and air nozzle of the oven cannot be effectively cleaned. Only the staff can manually disassemble the air nozzle and then clean it. However, the oven cooling time is long, and the time for disassembling and assembling the air nozzle is related to the operation proficiency of the staff, which cannot ensure timely resumption of normal production, and the air nozzle of the oven has the problems of low cleaning efficiency and cleaning difficulty.

[0060] In view of this, in order to solve the problem of low cleaning efficiency of the air nozzle of the oven, some embodiments of the present application provide an oven. The oven includes an oven body, an air outlet mechanism and a cleaning assembly. The oven body has a drying zone for taking away the material belt. The air outlet mechanism is arranged on the oven body. The air outlet mechanism includes an air nozzle for blowing air towards the drying zone. The air nozzle has an air outlet opening arranged along a first direction. The cleaning assembly is movably arranged in the oven body along the first direction. When the cleaning assembly is in a first position, the cleaning assembly is located on one side of the oven body in the first direction to be dislocated from the material belt of the drying zone. When the cleaning assembly is in a second position, the cleaning assembly is located in the drying zone and in contact with the air nozzle to clean the air nozzle.

[0061] In such an oven, the cleaning assembly is movably arranged in the oven body along the first direction and moves between the first position and the second position. The cleaning assembly is moved to the second position along the extension direction of the first air outlet opening on the air nozzle. The cleaning assembly is in contact with the air nozzle and cleans the waste material adhered to the air nozzle. Manual cleaning of the air nozzle is not required, and the cleaning efficiency of the air nozzle is improved. When the cleaning assembly completes the cleaning of the air nozzle, the cleaning assembly is moved to the first position. The cleaning assembly is located on one side of the oven body in the first direction, and the cleaning assembly is dislocated from the material belt of the drying zone. During the drying process of the material belt, the cleaning assembly does not interfere with the material belt, and the oven can normally dry the material belt.

[0062] The present application provides an oven. Please refer to Figures 1 to 9The oven 100 comprises an oven body 10, an air outlet mechanism 20 and a cleaning assembly 30. The oven body 10 has a drying area 13 for carrying the material. The air outlet mechanism 20 is arranged on the oven body 10 and comprises a nozzle 23 for blowing air towards the drying area 13. The nozzle 23 has an air outlet extending along a first direction X. The cleaning assembly 30 is movably arranged in the oven body 10 along the first direction X. When the cleaning assembly 30 is in a first position, the cleaning assembly 30 is located on one side of the oven body 10 along the first direction X and is out of position with the material belt of the drying area 13.

The air outlet of the nozzle 23 is a slit air outlet, and the air outlet of the nozzle 23 extends along the first direction X. The first direction X can be the width direction of the pole piece material belt. The cleaning assembly 30 is movably arranged on the oven body 10, and the movement of the cleaning assembly 30 along the first direction X can be a manual pushing mode or an electric push rod driving mode, which is determined according to the actual situation.

[0065] The first position refers to the position of the cleaning assembly 30 on one side of the oven body 10 along the first direction X, and the cleaning assembly 30 can be out of position with the material belt of the drying area 13 and will not affect the normal material carrying of the material belt. The second position refers to the position where the cleaning assembly 30 can be in contact with the nozzle 23, that is, the second position actually refers to all positions where the cleaning assembly 30 can be in contact with the nozzle 23 during the movement of the cleaning assembly 30 along the first direction X.

[0066] It should be noted that when the cleaning assembly 30 is used to clean the tuyere 23 of the oven, the oven is stopped to pause the feeding of the material belt. The cleaning assembly 30 is moved along the first direction X in the drying area 13 to clean the surface of the tuyere 23 along the extension direction of the air outlet of the tuyere 23. The cleaning assembly 30 can be set to clean the tuyere 23 regularly. After the cleaning assembly 30 completes the cleaning of the tuyere 23, the cleaning assembly 30 is withdrawn to the first position, and then the material belt can be normally fed, and the oven performs the drying operation on the material belt, and the cleaning assembly 30 does not interfere with the material belt.

[0067] In the technical scheme of the embodiments of the present application, the tuyere 23 in the air outlet mechanism 20 in the oven body 10 can blow hot air towards the drying area 13 to dry the material belt passing through the drying area 13. The cleaning assembly 30 is movably arranged in the oven body 10 along the first direction X and moves between the first position and the second position. The cleaning assembly 30 is moved to the second position along the extension direction of the first air outlet on the tuyere 23, the cleaning assembly 30 contacts the tuyere 23 and cleans the waste adhered to the tuyere 23, without the need for manual cleaning of the tuyere 23, thereby improving the cleaning efficiency of the tuyere 23. When the cleaning assembly 30 completes the cleaning of the tuyere 23, the cleaning assembly 30 is moved to the first position, the cleaning assembly 30 is located on one side of the oven body 10 along the first direction X, the cleaning assembly 30 is dislocated from the material belt in the drying area 13, and the cleaning assembly 30 does not interfere with the material belt during the drying of the material belt by the oven 100, so that the oven 100 can normally perform the drying operation on the material belt.

[0069] The driving assembly 40 can be a gas cylinder, a hydraulic cylinder, a gear rack, a screw nut pair mechanism, or an electric push rod, etc. The specific structure of the driving assembly 40 is determined according to the actual situation.

[0070] Through the arrangement of the driving assembly 40, the driving assembly 40 can drive the cleaning assembly 30 to move along the first direction X, without the need for manual pushing of the cleaning assembly 30, which is more labor-saving and reduces the labor intensity of the cleaning of the tuyere 23.

[0071] According to some embodiments of the present application, please refer to Figure 2 and Figure 3The air nozzle 23 has a first surface facing the cleaning assembly 30, and the air outlet is located on the first surface; the cleaning assembly 30 comprises a mounting base plate 31 connected with the driving assembly 40 and a main scraper 32 arranged on the mounting base plate 31; the main scraper 32 is used to contact the first surface of the air nozzle 23 to scrape off the waste on the first surface of the air nozzle 23.

[0072] The cleaning assembly 30 further comprises a first mounting portion 35 mounted on the mounting base plate 31 and used to mount the main scraper 32; the main scraper 32 is detachably connected with the first mounting portion 35, facilitating the mounting and dismounting of the main scraper 32.

[0073] The main scraper 32 and the first mounting portion 35 have multiple connection modes, for example, the first mounting portion 35 has a first scraper slot for mounting the main scraper 32, the main scraper 32 is inserted into the first scraper slot, and an end of the main scraper 32 away from the first mounting portion 35 extends out of the first scraper slot and is used to contact the first surface of the air nozzle 23. The first mounting portion 35 is provided with a first fastener 351 threadedly matched with the first mounting portion 35, one end of the first fastener 351 can extend into the first scraper slot and abut against the main scraper 32 to achieve abutting and fixing of the main scraper 32. When it is necessary to adjust the position of the main scraper 32 or dismount the main scraper 32, only the first fastener 351 needs to be loosened, which is convenient and fast. The number of the first fasteners 351 can be multiple.

[0074] The width of the main scraper 32 in the second direction Y should be not less than the width of the first surface of the air nozzle 23 in the second direction Y, so that the main scraper 32 can completely cover the first surface of the air nozzle 23 during the movement of the cleaning assembly 30 in the first direction X, realizing the scraping and cleaning of the first surface of the air nozzle 23. The second direction Y is perpendicular to the first direction X, and in the case that the first direction X is the width direction of the pole piece strip, the second direction Y is the length direction of the pole piece strip. In addition, the number of the main scrapers 32 can be one, two or three, and the specific number of the main scrapers 32 can be determined according to actual conditions.

[0075] The main scraper 32 is arranged on the mounting base plate 31, and the main scraper 32 is used to scrape off the waste adhered to the first surface of the air nozzle 23, realizing the cleaning of the air nozzle 23 and achieving good cleaning effect of the air nozzle 23.

[0076] According to some embodiments of the present application, please refer to Figure 4 and Figure 5 The number of the main scrapers 32 is two, and the two main scrapers 32 are distributed on the mounting base plate 31 in the first direction X.

[0077] The two main scrapers 32 can be of the same structure or different structures. In the embodiment, the two main scrapers 32 are of the same material. The main scrapers 32 can be made of non-metallic material, such as plastic, to prevent the generation of metal particles.

[0078] The number of the main scrapers 32 is set to two. The two main scrapers 32 can cooperate with each other, and are distributed along the first direction X on the mounting substrate 31. The two main scrapers 32 clean the first surface of the tuyere 23 from front to back, which is equivalent to that the two main scrapers 32 can clean the same area of the tuyere 23 twice, and the cleaning effect of the tuyere 23 is better.

[0079] According to some embodiments of the present application, please refer to Figure 5 The distance between the two main scrapers 32 gradually increases from the side of the main scraper 32 close to the mounting substrate 31 to the side of the main scraper 32 away from the mounting substrate 31.

[0080] The angle between the main scraper 32 and the mounting substrate 31 can be 30°-60°. That is, the angle between the main scraper 32 and the mounting substrate 31 can be 30°, 35°, 40°, 45°, 50°, 55° or 60°, etc. Alternatively, the angle between the main scraper 32 and the mounting substrate 31 is 45°.

[0081] The distance between the two main scrapers 32 gradually increases from the side of the main scraper 32 close to the mounting substrate 31 to the side of the main scraper 32 away from the mounting substrate 31, that is, the two main scrapers 32 are inclined and arranged in a m-shaped manner on the mounting substrate 31. When the main scraper 32 scrapes the waste material on the first surface of the tuyere 23, the inclined scraper can reduce the contact area with the first surface of the tuyere 23, thereby reducing the wear of the main scraper 32 and prolonging the service life of the main scraper 32. Moreover, by setting a reasonable inclination angle of the main scraper 32, compared with the vertical contact between the main scraper 32 and the first surface of the tuyere 23, under the condition of ensuring the scraping effect of the main scraper 32, the stress of the main scraper 32 contacting the tuyere 23 can be decomposed along the vertical direction Z and the horizontal direction, thereby reducing the pressure on the scraper and the tuyere 23.

[0082] According to some embodiments of the present application, please refer to Figure 4 and Figure 5 The cleaning assembly 30 further comprises a cleaning cotton 33, which is arranged on the mounting substrate 31 and located between the two main scrapers 32. The cleaning cotton 33 is used to contact the first surface of the tuyere 23 to wipe and clean the first surface of the tuyere 23.

[0083] In order to improve the cleaning effect of the cleaning cotton 33 on the air nozzle 23, the cleaning assembly 30 can further include a liquid supply system 38, which can supply cleaning liquid to the cleaning cotton 33 to wet the cleaning cotton 33, so that the wet cleaning cotton 33 can better clean the first surface of the air nozzle 23.

[0084] Please refer to Figure 1 , Figure 2 and Figure 7 The liquid supply system 38 can include a cleaning agent storage tank 381 and a screw pump 382. The cleaning agent storage tank 381 is arranged on the top of the oven main body 10, and the cleaning agent storage tank 381 is in communication with the screw pump 382. The liquid outlet of the screw pump 382 is communicated with the cleaning cotton 33 through a cleaning pipeline 383. The screw pump 382 can quantitatively deliver the cleaning agent in the cleaning agent storage tank 381 to the cleaning cotton 33 to wet the cleaning cotton 33, so that the cleaning cotton 33 can better clean the air nozzle 23.

[0085] Of course, please refer to Figure 5 The cleaning cotton 33 includes a cleaning plate 331 and a cleaning cotton strip 332. The cleaning plate 331 is installed on the installation base plate 31, and the cleaning cotton 33 cleans the first surface of the air nozzle 23 through the cleaning cotton strip 332. The cleaning cotton strip 332 is detachably installed on the cleaning plate 331. For example, the cleaning plate 331 can be provided with a magic tape, and the cleaning cotton strip 332 is attached to the cleaning plate 331, and the cleaning cotton strip 332 can be replaced regularly. The cleaning pipeline 383 passes through the installation base plate 31 and is in communication with the cleaning plate 331. The cleaning plate 331 has a flow channel in communication with the cleaning pipeline 383. The cleaning plate 331 is provided with a liquid outlet in communication with the flow channel on the side close to the cleaning cotton strip 332. The liquid outlet is used to supply cleaning agent to the cleaning cotton strip 332 to wet the cleaning cotton strip 332, so that the cleaning cotton strip 332 can better clean the first surface of the air nozzle 23.

[0086] Through the arrangement of the cleaning cotton 33, the cleaning cotton 33 can contact the first surface of the air nozzle 23 to clean the waste adhered to the first surface of the air nozzle 23. In the case that the main scraper 32 cleans the first surface of the air nozzle 23, the main scraper 32 cooperates with the cleaning cotton 33 to better clean the air nozzle 23.

[0087] According to some embodiments of the present application, please refer to Figure 3 and Figure 4The cleaning assembly 30 further comprises two side scrapers 34 arranged on the mounting base plate 31 on two sides of the second direction Y, respectively, and used to contact two sides of the blow nozzle 23 in the second direction Y to scrape off the waste on the two sides of the blow nozzle 23 in the second direction Y. The second direction Y, the first direction X and the vertical direction Z are perpendicular to each other.

[0088] The side scraper 34 refers to a scraper component capable of scraping the two sides of the blow nozzle 23 in the second direction Y. The cleaning assembly 30 further comprises a second mounting portion 36 mounted on the mounting base plate 31 and used to mount the side scraper 34. The side scraper 34 is detachably connected with the second mounting portion 36, facilitating the mounting and dismounting of the side scraper 34.

[0089] The side scraper 34 and the second mounting portion 36 have various connection modes. For example, the second mounting portion 36 has a second scraper groove for mounting the side scraper 34. The side scraper 34 is inserted into the second scraper groove, and an end of the side scraper 34 away from the second mounting portion 36 protrudes out of the second scraper groove and is used to contact the side wall of the blow nozzle 23. The second mounting portion 36 is provided with a second fastener 361 threadedly matched with the second mounting portion 36. An end of the second fastener 361 protrudes into the second scraper groove and abuts against the side scraper 34 to clamp and fix the side scraper 34. When it is necessary to adjust the position of the side scraper 34 or dismount the side scraper 34, the second fastener 361 only needs to be loosened, which is convenient and fast. The number of the second fastener 361 can be multiple, and the multiple second fasteners 361 are distributed on the second mounting portion 36 along the vertical direction Z.

[0090] Since the two sides of the blow nozzle 23 in the second direction Y can be adhered with waste, through the arrangement of the side scrapers 34 in the cleaning assembly 30, the two side scrapers 34 are arranged on the two sides of the second direction Y on the mounting base plate 31, respectively. During the movement of the cleaning assembly 30 in the first direction X, the two side scrapers 34 can scrape and clean the two sides of the blow nozzle 23 in the second direction Y, scrape off the waste adhered on the two sides of the blow nozzle 23 in the second direction Y, and clean a wider range of the blow nozzle 23 and achieve a better cleaning effect.

[0091] According to some embodiments of the present application, please refer to Figure 5 and Figure 6 The mounting base plate 31 is provided with a collection groove 37 on the side of the main scraper 32 away from the cleaning cotton 33, and the collection groove 37 is used to collect the waste scraped off by the main scraper 32 and / or the side scraper 34.

[0092] The collecting groove 37 refers to a component capable of collecting the waste scraped by the scraper. The collecting groove 37 is arranged on the mounting base plate 31 outside the main scraper 32. In order to facilitate the waste scraped by the side scraper 34 to fall into the collecting groove 37, the side scraper 34 can be arranged in a position collinear with the collecting groove 37 along the second direction Y, so that the waste scraped by the side scraper 34 directly falls into the collecting groove 37. The collecting groove 37 is provided with a slope to facilitate the collection of the scraped waste.

[0093] In addition, please refer to Figure 1 and Figure 2 , the oven 100 can further include a waste collecting mechanism 39, the waste collecting mechanism 39 includes a dust collector 391 and an exhaust pipeline, the dust collector 391 can be arranged on one side of the top of the oven body 10, one end of the exhaust pipeline is in communication with the dust collector 391, and the other end is in communication with the groove bottom of the collecting groove 37. The dust collector 391 forms a negative pressure at the opening of the collecting groove 37 through the exhaust pipeline, so as to negatively absorb the waste scraped near the side scraper 34 and the main scraper 32 and transfer the waste into the waste collecting box of the dust collector 391.

[0094] By arranging the collecting groove 37 on the mounting base plate 31, the waste scraped by the main scraper 32 and / or the side scraper 34 can fall into the collecting groove 37. The collecting groove 37 can collect the waste, avoid the waste scraped by the main scraper 32 and the side scraper 34 from being scattered everywhere, and improve the cleaning degree of the cleaning assembly 30 on the oven.

[0095] According to some embodiments of the present application, please refer to Figure 2 , the oven body 10 has a first wall 11 and a second wall 12 relatively distributed in the vertical direction Z; the air outlet mechanism 20 includes an upper hull 21 and a lower hull 22, the upper hull 21 and the lower hull 22 are respectively located on the first wall 11 and the second wall 12 of the oven body 10, a plurality of tuyeres 23 are alternately and spacedly arranged on the upper hull 21 and the lower hull 22 along the second direction Y, the area between the upper hull 21 and the lower hull 22 forms a drying zone 13 through which the material supply belt passes, and the second direction Y is perpendicular to the first direction X; the number of the cleaning assemblies 30 is multiple, and the positions and the numbers of the multiple cleaning assemblies 30 one-to-one correspond to the positions and the numbers of the multiple tuyeres 23.

[0096] For the multiple air nozzles 23 on the upper hull 21 and lower hull 22, the number of drive components 40 can be set as one group or multiple groups. When multiple drive components 40 are set, each cleaning component 30 can be equipped with one drive component 40, enabling independent driving of each cleaning component 30, and each cleaning component 30 can independently clean its corresponding air nozzle 23. Alternatively, the number of drive components 40 can be set as one group, with multiple cleaning components 30 corresponding to one drive component 40, achieving synchronous overall driving of multiple cleaning components 30. This simplifies the structural complexity of the drive components 40, reduces cost, and reduces the internal space occupied by the drive components 40 in the oven body 10.

[0097] Furthermore, when the mounting base plate 31 has a collection groove 37, for the cleaning component 30 of the air nozzle 23 on the upper hull 21, the cleaning component 30 is located below the air nozzle 23. The slurry scraped off by the cleaning component 30 falls into the collection groove 37 under gravity. Even without a waste collection mechanism 39, the waste can be temporarily stored. However, for the cleaning component 30 at the air nozzle 23 on the lower hull 22, the cleaning component 30 is located above the air nozzle 23. Therefore, a waste collection mechanism 39 is required to create a negative pressure suction at the collection groove 37, which can effectively absorb the waste. Of course, even if some waste is not absorbed into the waste collection mechanism 39 by the negative pressure, the waste will fall into the space below the oven body. The waste will not fall onto the roller 70 and will not have much impact on it. It is only necessary to periodically treat the waste accumulated at the bottom of the oven body 10.

[0098] The oven also includes a guide roller 70, which is distributed between two adjacent air nozzles 23 on the lower hull 22. The guide roller 70 is used to guide the electrode material strip through the drying zone 13.

[0099] Multiple air nozzles 23 are spaced apart along the second direction Y on the upper hull 21 and the lower hull 22. The conveyor belt passes through the drying zone 13 along the second direction Y, and the air nozzles 23 on the upper hull 21 and the lower hull 22 dry both sides of the conveyor belt respectively. By setting the number of cleaning components 30 to multiple, and the positions and numbers of the multiple cleaning components 30 corresponding one-to-one with the positions and numbers of the multiple air nozzles 23, the cleaning of each air nozzle 23 can be achieved without manual cleaning, thus improving the cleaning efficiency of the air nozzles 23 and achieving good cleaning effect.

[0100] Based on some embodiments of this application, please refer to... Figure 1 , Figure 2 and Figure 7 The drive assembly 40 includes a connecting frame 41 and a drive component 42. The connecting frame 41 is used to connect multiple cleaning components 30 into a whole. The drive component 42 is disposed on the oven body 10 and is used to drive the connecting frame 41 to move along the first direction X.

[0101] The connecting frame 41 can be a frame structure, and in the embodiment, the connecting frame 41 is an I-shaped frame. The number of the driving members 42 can be two or four, which is determined according to actual conditions. Optionally, taking the case of four driving members 42 as an example, the four driving members 42 are respectively located at the four corners of the oven main body 10, the connecting frame 41 is connected with the four driving members 42, and the connecting frame 41 is driven to move along the first direction X by the four driving members 42, so as to drive the plurality of cleaning assemblies 30 to move synchronously, which is good in integrity and high in structural stability. The driving member 42 can be a pneumatic cylinder, a hydraulic cylinder, an electric push rod, a gear and rack mechanism, or a screw and nut pair mechanism, which is determined according to actual conditions. In the embodiment, the driving member 42 is a pneumatic cylinder.

[0102] In addition, in the case that the cleaning assembly 30 has the liquid supply system 38 and the waste collecting mechanism 39, a channel or a cavity for arranging the cleaning pipeline 383 and the exhaust pipeline can be formed in the connecting frame 41. That is, part of the cleaning pipeline 383 is arranged in the connecting frame 41, and the cleaning pipeline 383 is connected to the cleaning cotton 33 after passing through the mounting base plate 31. Part of the exhaust pipeline is also arranged in the connecting frame 41, and is arranged independently from the cleaning pipeline 383, and the exhaust pipeline passes through the mounting base plate 31 and is connected to the collecting groove 37.

[0103] Through the arrangement of the connecting frame 41, the connecting frame 41 can connect the plurality of cleaning assemblies 30 into a whole, compared with the case that each cleaning assembly 30 is provided with a driving assembly 40, the number of the driving assemblies 40 is reduced, and the cost is lower. In addition, the reduction of the number of the driving assemblies 40 also reduces the space occupied by the driving assemblies 40, which is more conducive to the spatial layout of the cleaning assemblies 30 in the oven main body 10.

[0104] According to some embodiments of the present application, please refer to Figure 1 , Figure 2 and Figure 7 , the driving assembly 40 further comprises a guide portion 43, the guide portion 43 is arranged on the oven main body 10 along the first direction X, the connecting frame 41 has a sliding portion which is in sliding cooperation with the guide portion 43, and the sliding portion is in sliding cooperation with the guide portion 43.

[0105] The guide portion 43 refers to a guide portion 43 which can guide the movement of the connecting frame 41, and the guide portion 43 can be a guide rail, a sliding groove, or a guide rod. The specific structure of the guide portion 43 can be determined according to actual conditions. In the embodiment, the guide portion 43 is a guide rail, and the sliding portion is a sliding block.

[0106] With the guide part 43 provided, the connecting frame 41 has a sliding part that slides in cooperation with the guide part 43. The guide part 43 slides in cooperation with the sliding part of the connecting frame 41, which can guide the connecting frame 41 to move along the first direction X, thereby improving the stability and accuracy of the multiple cleaning components 30 during the movement in the first direction X, and resulting in a better cleaning effect on the nozzle 23.

[0107] According to some embodiments of this application, there are multiple guide portions 43, which are respectively distributed on both sides of the oven body 10 in the second direction Y.

[0108] With four driving components 42, there can also be four guide portions 43. These four guide portions 43 are divided into two groups and distributed on opposite sides of the oven body 10 in the second direction Y. The second direction Y can be the length direction of the material strip, i.e., the length direction of the oven body 10. Two guide portions 43 in each group are located on the side walls of the oven body 10, close to the first wall 11 and the second wall 12. Correspondingly, the connecting frame 41 has four sliding portions, which slide in conjunction with the four guide portions 43, guiding the movement of the connecting frame 41.

[0109] By distributing multiple guide parts 43 on both sides of the oven body 10 in the second direction Y, the guide parts 43 are less likely to interfere with the air nozzles 23 inside the oven body 10. Furthermore, the multiple guide parts 43 work together, and there are multiple support points between the connecting frame 41 and the multiple guide parts 43, making the connecting frame 41 more stable during movement.

[0110] According to some embodiments of this application, please refer to Figure 8 and Figure 9 A height adjustment component 50 is provided between the connecting frame 41 and the cleaning component 30. The height adjustment component 50 is used to adjust the position of the cleaning component 30 relative to the nozzle 23 in the vertical direction Z.

[0111] The height adjustment component 50 refers to an adjustment component capable of fine-tuning the relative position of the cleaning component 30 relative to the connecting frame 41. The height adjustment component 50 can be of various types, such as a cylinder or an adjusting nut. Taking a cylinder as an example, the height adjustment component 50 is positioned between the connecting frame 41 and the mounting base 31 of the cleaning component 30. The height adjustment component 50 can cause the mounting base 31 to move relative to the connecting frame 41, thereby allowing the cleaning component 30 to engage with the corresponding nozzle 23.

[0112] Of course, the cleaning assembly 30 may be locally tilted during actual use, which may cause the cleaning cotton 33 or the scraper of the cleaning assembly 30 to not completely adhere to the first surface of the air nozzle 23. In this case, the cleaning assembly 30 needs to be locally adjusted. Therefore, the height adjusting member 50 can include an adjusting seat 51, an adjusting screw 52, and a lifting rod 53. The adjusting seat 51 is arranged on and connected to the connecting frame 41, as shown in Figure 8 The two ends of the lifting rod 53 can be connected to two adjacent groups of cleaning assemblies 30, respectively. Of course, as shown in Figure 9 One height adjusting member 50 is arranged on each side of the cleaning assembly 30. The lifting rod 53 of the height adjusting member 50 is connected to the corresponding cleaning assembly 30.

[0113] Please refer to Figure 8 and Figure 9 The adjusting screw 52 is rotatably arranged on the adjusting seat 51. The adjusting screw 52 is threadedly connected to the lifting rod 53. By rotating the adjusting screw 52, the adjusting screw 52 drives the lifting rod 53 to move up and down, thereby driving the positions of the two adjacent groups of cleaning assemblies 30 to be adjusted up and down relative to the connecting frame 41. By rotating the adjusting screw 52, the cleaning cotton 33 and the scraper of the cleaning assembly 30 can be made to adhere to the first surface of the air nozzle 23.

[0114] In order to improve the installation stability of the cleaning assembly 30, please refer to Figure 9 A deformed portion 60 can be arranged between the mounting base plate 31 of the cleaning assembly 30 and the connecting frame 41. The deformed portion 60 can be made of rubber, and of course, the deformed portion 60 can also be a spring. The deformed portion 60 can allow the mounting base plate 31 of the cleaning assembly 30 and the connecting frame 41 to be slightly deformed relative to each other. In the case that the cleaning assembly 30 has a liquid supply system 38 and a waste collecting mechanism 39, part of the cleaning pipeline 383 is arranged in the connecting frame 41. The cleaning pipeline 383 is connected to the cleaning cotton 33 after passing through the deformed portion 60 and the mounting base plate 31. The exhaust pipeline is also arranged in the connecting frame 41 and is independently arranged with the cleaning pipeline 383. The exhaust pipeline also passes through the deformed portion 60 and the mounting base plate 31 and is connected to the collecting groove 37 of the mounting base plate 31. The regions of the cleaning pipeline 383 and the exhaust pipeline in the deformed portion 60 are flexible hoses or elastic tubes, which can meet the deformation requirements of the deformed portion 60.

[0115] In order to improve the adhesion of the cleaning assembly 30 to the air nozzle 23, the height adjusting member 50 is arranged between the connecting frame 41 and the cleaning assembly 30. The height adjusting member 50 can drive the cleaning assembly 30 to be adjusted in the vertical direction Z relative to the connecting frame 41, so that the cleaning assembly 30 can better adhere to the corresponding air nozzle 23. The cleaning assembly 30 can effectively clean the air nozzle 23.

[0116] The application further provides a battery manufacturing device, which comprises the oven.

[0117] In some embodiments, referring to Figures 1 to 9 The oven 100 comprises an oven body 10, an air outlet mechanism 20 and a cleaning assembly 30. The oven body 10 has a drying area 13 for carrying the material strip. The air outlet mechanism 20 is arranged on the oven body 10 and comprises a nozzle 23 for blowing air towards the drying area 13. The nozzle 23 has an air outlet arranged along a first direction X. The cleaning assembly 30 is movably arranged in the oven body 10 along the first direction X. When the cleaning assembly 30 is in a first position, the cleaning assembly 30 is located on one side of the oven body 10 along the first direction X and is out of position with the material strip of the drying area 13. When the cleaning assembly 30 is in a second position, the cleaning assembly 30 is located in the drying area 13 and is in contact with the nozzle 23 to clean the nozzle 23. The oven further comprises a driving assembly 40 arranged on the oven body 10. The driving assembly 40 is used to drive the cleaning assembly 30 to move along the first direction X between the first position and the second position.

[0118] The cleaning assembly 30 is movably arranged in the oven body 10 along the first direction X and moves between the first position and the second position. When the cleaning assembly 30 moves to the second position along the extension direction of the first air outlet on the nozzle 23, the cleaning assembly 30 is in contact with the nozzle 23 and cleans the waste adhered to the nozzle 23. The cleaning of the nozzle 23 is improved without manual cleaning, and the cleaning efficiency of the nozzle 23 is improved. When the cleaning assembly 30 completes the cleaning of the nozzle 23, the cleaning assembly 30 moves to the first position and is located on one side of the oven body 10 along the first direction X. The cleaning assembly 30 is out of position with the material strip of the drying area 13. During the drying of the material strip, the cleaning assembly 30 does not interfere with the material strip, and the oven 100 can perform normal drying operation on the material strip. The driving assembly 40 is arranged to drive the cleaning assembly 30 to move along the first direction X. The cleaning assembly 30 does not need to be manually pushed to move, which is more labor-saving and reduces the labor intensity of the cleaning of the nozzle 23.

[0119] In some embodiments, the nozzle 23 has a first surface facing the cleaning assembly 30, and the air outlet is located on the first surface. The cleaning assembly 30 comprises a mounting base plate 31 and a main scraper 32. The mounting base plate 31 is connected with the driving assembly 40. The main scraper 32 is arranged on the mounting base plate 31. The main scraper 32 is used to contact the first surface of the nozzle 23 to scrape off the waste on the first surface of the nozzle 23. The number of the main scrapers 32 is two. The two main scrapers 32 are spaced apart on the mounting base plate 31 along the first direction X. The distance between the two main scrapers 32 gradually increases from the side of the main scraper 32 close to the mounting base plate 31 to the side of the main scraper 32 away from the mounting base plate 31.

[0120] The main scrapers 32 are arranged on the mounting substrate 31, and the main scrapers 32 are used to scrape the waste adhered on the first surface of the tuyere 23, so as to clean the tuyere 23, and the cleaning effect of the tuyere 23 is good. The two main scrapers 32 can cooperate with each other, and the two main scrapers 32 are distributed along the first direction X on the mounting substrate 31, and the two main scrapers 32 clean the first surface of the tuyere 23 in front and back, which is equivalent to that the two main scrapers 32 can clean the same area of the tuyere 23 twice, and the cleaning effect of the tuyere 23 is better. The two main scrapers 32 are arranged in an eight-shaped manner on the mounting substrate 31, and when the main scrapers 32 scrape the waste on the first surface of the tuyere 23, the scrapers arranged in an inclined manner can reduce the contact area with the first surface of the tuyere 23, so as to reduce the abrasion of the main scrapers 32 and prolong the service life of the main scrapers 32. Moreover, by reasonably setting the inclination angle of the main scrapers 32, compared with the vertical contact between the main scrapers 32 and the first surface of the tuyere 23, under the condition of ensuring the scraping effect of the main scrapers 32, the stress of the main scrapers 32 contacting the tuyere 23 can be decomposed along the vertical direction Z and the horizontal direction, so as to reduce the pressure on the scrapers and the tuyere 23.

[0121] In some embodiments, the cleaning assembly 30 further comprises cleaning cotton 33, which is arranged on the mounting substrate 31 and located between the two main scrapers 32. The cleaning cotton 33 is used to contact the first surface of the tuyere 23 to wipe and clean the first surface of the tuyere 23. The cleaning assembly 30 further comprises two side scrapers 34, which are respectively arranged on the mounting substrate 31 on both sides of the second direction Y. The two side scrapers 34 are respectively used to contact both sides of the second direction Y of the tuyere 23 to scrape the waste on both sides of the second direction Y of the tuyere 23. The second direction Y, the first direction X and the vertical direction Z are perpendicular to each other. The mounting substrate 31 is provided with a collection groove 37 on the side away from the cleaning cotton 33 of the main scraper 32, and the collection groove 37 is used to collect the waste scraped by the main scraper 32 and / or the side scraper 34.

[0122] The cleaning cotton 33 can be in contact with the first surface of the air nozzle 23 to wipe and clean the waste adhered to the first surface of the air nozzle 23. In the case that the main scraper 32 is in contact with the first surface of the air nozzle 23, the main scraper 32 cooperates with the cleaning cotton 33 to achieve better cleaning effect on the air nozzle 23. Since the two sides of the air nozzle 23 in the second direction Y can be adhered with waste, the two side scrapers 34 are respectively arranged on the two sides of the second direction Y on the mounting base plate 31, so that the two side scrapers 34 can scrape and clean the two sides of the air nozzle 23 in the second direction Y during the movement of the cleaning assembly 30 in the first direction X. The two sides of the air nozzle 23 in the second direction Y are scraped and cleaned to remove the waste adhered to the two sides of the air nozzle 23 in the second direction Y. The cleaning assembly 30 has a wider cleaning range and better cleaning effect on the air nozzle 23. The collection groove 37 is formed on the mounting base plate 31, so that the waste scraped by the main scraper 32 and / or the side scraper 34 can fall into the collection groove 37. The collection groove 37 can collect the waste to avoid the waste scraped by the main scraper 32 and the side scraper 34 from being scattered everywhere, thereby improving the cleaning degree of the cleaning assembly 30 on the oven.

[0123] In some embodiments, the oven body 10 has a first wall 11 and a second wall 12 which are oppositely distributed in the vertical direction Z; the air outlet mechanism 20 includes an upper hull 21 and a lower hull 22, the upper hull 21 and the lower hull 22 are respectively arranged on the first wall 11 and the second wall 12 of the oven body 10, a plurality of air nozzles 23 are alternately and spacedly arranged on the upper hull 21 and the lower hull 22 in the second direction Y, the area between the upper hull 21 and the lower hull 22 forms a drying area 13 through which the feeding belt passes, and the second direction Y is perpendicular to the first direction X; the number of cleaning assemblies 30 is multiple, and the positions and numbers of the multiple cleaning assemblies 30 correspond to the positions and numbers of the multiple air nozzles 23 one by one.
