Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning and dust removal device and a battery production system. Background Art

[0002] In the battery production process, lithium battery materials need to be loaded into saggers, and the saggers containing lithium battery materials are sent to the kiln for reaction. During the production process, dust usually adheres to the surface of the saggers. If the dust is output from the kiln with the saggers, it can affect the cleanliness of the site and the quality of the finished battery. Therefore, the surface of the saggers needs to be cleaned online. However, due to the structural design of traditional dust removal devices, not only is the cleaning operation complicated, but it also causes dust to easily enter the equipment, shortening the service life of the equipment and increasing maintenance costs. Utility Model Content

[0003] Based on this, it is necessary to provide a cleaning and dust removal device and a battery production system with a simple structure and easy operation; at the same time, it reduces the probability of dust entering the equipment and extends the service life of the equipment.

[0004] In the first aspect, the present application provides a cleaning and dust removal device, which includes: a conveying mechanism for transmitting workpieces; a cleaning mechanism, which is arranged on the conveying mechanism and includes a cleaning piece and a brush and a suction nozzle arranged on the cleaning piece, the suction nozzle is used to connect with the suction equipment, and the brush is used to contact the workpiece on the conveying mechanism.

[0005] The above-mentioned cleaning and dust removal device drives the workpiece forward through the conveying mechanism. When the workpiece contacts the brush, the relative friction between the brush and the workpiece is used to effectively clean the surface of the workpiece. It has a simple structure and convenient cleaning operation. Since the cleaning piece is also provided with a suction nozzle, the dust swept by the brush is sucked into the suction nozzle under the suction of the suction device so as to be effectively collected. The suction nozzle and the brush are both arranged on the cleaning piece, so that the dust suction and cleaning actions are concentrated on the cleaning piece, so that the swept dust can be sucked in time, reducing the probability of the swept dust easily entering the equipment due to outward diffusion, which is beneficial to prolonging the service life of the equipment.

[0006] In some embodiments, the cleaning mechanism has a cleaning channel, the brush and the suction nozzle are both arranged toward the cleaning channel, and the conveying mechanism is used to drive the workpiece through the cleaning channel. With such a design, the cleaning channel is introduced to facilitate the brush and the suction nozzle to clean and dust the workpiece respectively, thereby improving the dust removal effect.

[0007] In some embodiments, the cleaning members include more than two, and all the cleaning members are enclosed to form a cleaning channel. Such a design, using more than two cleaning members to enclose a cleaning channel, not only facilitates the brush and the suction nozzle to better act on the workpiece in the cleaning channel, but also expands the cleaning range, facilitates effective cleaning of the circumference of the workpiece, and improves the cleaning force.

[0008] In some embodiments, all cleaning pieces are connected end to end in sequence to form a cleaning channel, and the interiors of at least two cleaning pieces are interconnected, and the suction nozzle is used to communicate with the suction device through the interior of the cleaning piece. With such a design, the end-to-end connection facilitates the improvement of the stability of the structure; at the same time, it facilitates the mutual flow of dust in some cleaning pieces, which is conducive to reducing the number of connections of the suction device on the cleaning mechanism and simplifying the structural design.

[0009] In some embodiments, a conveying surface for workpiece transmission is defined on the conveying mechanism, the conveying surface passes through the cleaning channel, and in the height direction of the cleaning and dust removal device, the surface of the relatively low cleaning member is lower than or flush with the conveying surface. Such a design is conducive to the smooth entry of the workpiece into the cleaning channel, so that the dust removal operation can be carried out stably.

[0010] In some embodiments, the brushes include a plurality of brushes, all of which are sequentially distributed along the length direction of the cleaning piece to form a cleaning area, and the suction nozzle is disposed on at least one side of the cleaning area along the conveying direction of the conveying mechanism. With such a design, the cleaning area formed can increase the cleaning range of the brush on the workpiece and improve the dust removal effect; at the same time, the brush and the suction nozzle act on the workpiece in sequence, which is conducive to further improving the dust removal effect.

[0011] In some embodiments, the cleaning element has a suction channel connected to the suction nozzle, and the suction channel is used to communicate with the suction device. Such a design allows the dust sucked by the suction nozzle to directly enter the interior of the cleaning element, further reducing the probability of dust diffusion, which is beneficial to improving the on-site cleanliness and the service life of the equipment.

[0012] In some embodiments, the cleaning mechanism further comprises a joint, which is communicated with the suction channel and is used to connect with the suction device. With such a design, the joint is introduced to facilitate the connection between the suction device and the suction channel, thereby improving the assembly efficiency of the device.

[0013] In some embodiments, the cleaning mechanism further includes a collection box, which is used to receive dust discharged from the suction channel. With such a design, the collection box is introduced to effectively collect the dust, which facilitates the unified treatment of the collected dust.

[0014] In some embodiments, the cleaning mechanism includes more than two, and all cleaning mechanisms are sequentially distributed along the conveying direction of the conveying mechanism. In this design, the cleaning mechanisms are sequentially distributed along the conveying direction, so that the workpiece can be cleaned at least twice, which greatly improves the cleaning force and improves the dust removal effect.

[0015] In some embodiments, the cleaning and dust removal device further comprises a connecting piece, and a connecting piece is connected between two adjacent cleaning mechanisms. With such a design, the connecting piece is introduced so that the two adjacent cleaning mechanisms are stably connected, thereby enabling the cleaning mechanisms to operate stably on the conveying mechanism.

[0016] In some embodiments, the conveying mechanism includes a support frame and a plurality of conveying rollers rotatably arranged on the support frame, all of which are arranged in parallel and spaced apart along the conveying direction of the conveying mechanism, and the cleaning mechanism is arranged on the support frame. Such a design allows the workpiece to be conveyed stably; at the same time, it also achieves stable contact with the brush, thereby achieving effective cleaning.

[0017] In a second aspect, the present application provides a battery production system, which includes any one of the above cleaning and dust removal devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0028] In the battery production process, lithium battery materials need to be loaded into saggers, and the saggers containing lithium battery materials are sent to the kiln for reaction. In the production process, dust usually adheres to the surface of the saggers. If the dust is output from the kiln together with the saggers, it will not only cause the adhered dust to fall on the production site, affecting the cleanliness of the site. At the same time, in the production process, some dust on the surface of the saggers may be mixed into the finished powder. In this way, when it enters the kiln for chemical reaction again, it will affect the consistency of the finished powder and reduce the quality of the finished battery.

[0029] To this end, conventional dust removal devices generally use a lifting mechanism to drive the sagger up and down, so that the sagger and the brush rub against each other to scrape off the dust on the surface of the sagger; at the same time, the dust removal pipe is used to vacuum the entire dust removal device. However, this dust removal device is not only complicated to operate, but also easily causes the scraped dust to enter the lifting mechanism or other equipment, shortening the service life of the equipment and increasing maintenance costs.

[0030] Based on this, in view of the problems existing in traditional dust removal devices, such as complicated operation, shortened equipment life, and increased maintenance costs, the present application provides a cleaning and dust removal device, which drives the sagger forward through a conveying mechanism. When the sagger contacts the brush, the relative friction between the brush and the sagger is utilized to achieve effective cleaning of the sagger surface. The structure is simple and the cleaning operation is convenient. Since the cleaning member is also provided with a suction nozzle, the dust swept down by the brush is sucked into the suction nozzle under the suction of the suction device so as to be effectively collected. The suction nozzle and the brush are both arranged on the cleaning member, so that the dust suction and cleaning actions are concentrated on the cleaning member, so that the swept dust can be sucked in time, reducing the probability that the swept dust easily enters the equipment due to outward diffusion, which is conducive to extending the service life of the equipment.

[0031] It should be noted that the cleaning and dust removal device provided in the present application is not only suitable for cleaning the sagger in the battery production process, but also suitable for cleaning any object with dust on the surface.

[0032] According to some embodiments of this application, please refer to Figure 1 The present application provides a cleaning and dust removal device 100, which includes: a conveying mechanism 10 and a cleaning mechanism 20. The conveying mechanism 10 is used to transport workpieces, and the cleaning mechanism 20 is arranged on the conveying mechanism 10, and includes a cleaning member 21 and a brush 23 and a suction nozzle 22 arranged on the cleaning member 21. The suction nozzle 22 is used to communicate with a suction device, and the brush 23 is used to contact the workpiece on the conveying mechanism 10.

[0033] The conveying mechanism 10 refers to a structure that can drive the workpiece to move to a specific workstation, for example, the conveying mechanism 10 can drive the workpiece to move to the input end of the next process or in front of the furnace mouth of the kiln, etc. The structure of the conveying mechanism 10 can be designed in many ways, such as a belt conveyor, a chain conveyor, a roller conveyor, etc. Among them, the workpiece can be an object whose surface needs to be cleaned, such as but not limited to a sagger.

[0034] The cleaning mechanism 20 refers to a device that can clean and remove dust from the surface of a workpiece. In the cleaning mechanism 20, the cleaning member 21 refers to a structure for the brush 23 to be installed and fixed. The structure can be designed in a variety of ways, such as being cylindrical or plate-shaped. At the same time, in order to facilitate the brush 23 on the cleaning member 21 to contact the workpiece on the conveying mechanism 10, the cleaning member 21 can be set on one side along the direction intersecting with the conveying direction X of the conveying mechanism 10, or can be set above or below the cleaning mechanism 20. Of course, the cleaning member 21 can also be designed as a semicircular structure, and the cover is set above the cleaning mechanism 20.

[0035] In the cleaning process, the workpiece is moved under the drive of the conveying mechanism 10, and when it moves to the cleaning station, it contacts the brush 23. Then, as the workpiece continues to move, relative friction is generated between the brush 23, so that the dust on the surface of the workpiece is scraped off.

[0036] In the cleaning mechanism 20, the suction nozzle 22 refers to a component that can suck dust under the action of the suction device. The suction nozzle 22 and the brush 23 are installed together on the same cleaning member 21, so that the dust scraped by the brush 23 will be sucked in by the suction nozzle 22 in time. There can be many distributions between the suction nozzle 22 and the brush 23, for example: a plurality of brushes 23 can be arranged around the suction nozzle 22; or, a plurality of suction nozzles 22 can be arranged around the brush 23.

[0037] In addition, the suction nozzle 22 can be directly connected to the suction device through a pipe, for example: the suction nozzle 22 is fixed on the cleaning piece 21, and then the suction nozzle 22 and the suction device are connected through a pipe located outside the cleaning piece 21; it can also be connected to the suction device through the inside of the cleaning piece 21, for example: a suction channel 211 is set inside the cleaning piece 21, the suction nozzle 22 is fixed on the cleaning piece 21, and is connected to the suction channel 211, and the suction channel 211 is also connected to the suction device.

[0038] With such a design, the suction nozzle 22 and the brush 23 are both arranged on the cleaning member 21, so that the dust suction and cleaning actions are concentrated on the cleaning member 21, so that the swept dust can be sucked out in time, reducing the probability of the swept dust easily entering the equipment due to outward diffusion, which is beneficial to extending the service life of the equipment.

[0039] According to some embodiments of the present application, optionally, please refer to Figure 1The cleaning mechanism 20 has a cleaning channel 24 , the brush 23 and the suction nozzle 22 are both arranged toward the cleaning channel 24 , and the conveying mechanism 10 is used to drive the workpiece through the cleaning channel 24 .

[0040] The cleaning channel 24 refers to a channel structure through which the workpiece can pass. When the conveying mechanism 10 drives the workpiece into the cleaning channel 24, since the brush 23 and the suction nozzle 22 are both arranged toward the cleaning channel 24, the brush 23 can contact the workpiece in the cleaning channel 24 and scrape off the dust on the workpiece. At this time, the suction nozzle 22 sucks the dust in the cleaning channel 24 under the action of the suction device.

[0041] The shape of the cleaning channel 24 can be designed in many ways, as long as it allows the workpiece to pass through. For example, the cross-sectional shape of the cleaning channel 24 can be, but not limited to, circular, elliptical, square, rectangular, etc., or an irregular shape. In addition, the cleaning channel 24 can be composed of one cleaning member 21, or can be formed by a plurality of cleaning members 21. When the cleaning channel 24 is composed of one cleaning member 21, the cleaning member 21 can be designed to be a curved or bent structure.

[0042] With such a design, the cleaning channel 24 is introduced, so that the brush 23 and the suction nozzle 22 can clean and dust the workpiece respectively, thereby improving the dust removal effect.

[0043] According to some embodiments of the present application, optionally, please refer to Figure 1 The cleaning members 21 include more than two, and all the cleaning members 21 are enclosed to form a cleaning channel 24.

[0044] When the cleaning parts 21 are enclosed to form the cleaning channel 24, the cleaning parts 21 can be connected to each other or separated from each other. When the cleaning parts 21 are separated and not connected, they need to be supported by other structures. At the same time, if the cleaning parts 21 are separated and not connected, the cleaning parts 21 can be designed as movable structures. For example, some cleaning parts 21 can be connected to power equipment with telescopic functions such as cylinders, hydraulic cylinders or electric cylinders, and the power equipment is used to drive the cleaning parts 21 to move toward or away from one side of the cleaning channel 24 to change the size of the internal space of the cleaning channel 24.

[0045] The number of cleaning parts 21 may not be limited to Figure 1 For example, the number of cleaning members 21 is two, three, five, etc. When there are four cleaning members 21, two of them are arranged side by side and spaced apart in the height direction Y of the cleaning and dust removal device 100, and the other two cleaning members 21 are arranged side by side and spaced apart in the direction intersecting the conveying direction X.

[0046] In addition, in some examples, the suction nozzle 22 and the brush 23 are both arranged on a side surface of the cleaning member 21 facing the cleaning channel 24 .

[0047] Such a design utilizes more than two cleaning members 21 to enclose and form a cleaning channel 24, which not only facilitates the brush 23 and the suction nozzle 22 to better act on the workpiece in the cleaning channel 24, but also expands the cleaning range, facilitates effective cleaning of the circumference of the workpiece, and improves the cleaning force.

[0048] According to some embodiments of the present application, optionally, please refer to Figure 1 All cleaning members 21 are connected end to end in sequence to form a cleaning channel 24, and the interiors of at least two cleaning members 21 are interconnected, and the suction nozzle 22 is connected to the suction device through the interior of the cleaning member 21.

[0049] The cleaning member 21 is connected end to end to form a closed cleaning channel 24, which can improve the structural stability of the cleaning channel 24. The suction nozzle 22 is connected to the suction device through the inside of the cleaning member 21, which means that there is a certain space inside the cleaning member 21, which can realize the connection between the suction nozzle 22 and the suction device. For example, the cleaning member 21 has a suction channel 211, the suction nozzle 22 is arranged on the cleaning member 21 and is connected to the suction channel 211, and the suction channel 211 is connected to the suction device.

[0050] Since the interiors of at least two cleaning members 21 can be interconnected, when the suction nozzle 22 sucks dust into the interior of one of the cleaning members 21, the dust can flow into the interior of the other cleaning member 21. At this time, only one of the two cleaning members 21 needs to be connected to the suction device, which can reduce the number of connections of the suction device on the cleaning mechanism 20.

[0051] In some examples, the cleaning members 21 are connected in sequence, and the suction channel 211 of the first cleaning member 21 is not directly connected to the suction channel 211 of the last cleaning member 21. The suction channel 211 of the first cleaning member 21 or the last cleaning member 21 is connected to the suction device. The first cleaning member 21 and the last cleaning member 21 refer to the cleaning members 21 that are in the first position and the last position, respectively, in the cleaning members 21 that enclose the cleaning channel 24, in a clockwise or counterclockwise direction.

[0052] With such a design, the head-to-tail connection facilitates the improvement of the stability of the structure; at the same time, it facilitates the mutual flow of dust in some cleaning parts 21, which is beneficial to reduce the number of connections of the suction equipment on the cleaning mechanism 20 and simplify the structural design.

[0053] According to some embodiments of the present application, optionally, please refer to Figure 1 A conveying surface 13 for transporting workpieces is defined on the conveying mechanism 10 , and the conveying surface 13 passes through a cleaning channel 24 , and in the height direction Y of the cleaning and dust removing device 100 , the surface of the relatively low cleaning member 21 is lower than or flush with the conveying surface 13 .

[0054] The conveying surface 13 refers to a surface structure that supports the workpiece and allows the workpiece to move. When the conveying mechanism 10 is a belt conveyor, the conveying surface 13 is the surface of the belt; when the conveying mechanism 10 is a roller conveyor, the conveying surface 13 is a surface structure formed by combining the surfaces of several rollers; when the conveying mechanism 10 is a conveyor with rollers, the conveying surface 13 is a surface structure formed by combining the tops of the various rollers. The conveying surface 13 passes through the cleaning channel 24, which means that the workpiece located on the conveying surface 13 can pass through the cleaning channel 24.

[0055] In the height direction Y, the surface of the relatively low cleaning member 21 is lower than or flush with the conveying surface 13, so that when the workpiece enters the cleaning channel 24, it will not collide with the cleaning member 21. In addition, when the surface of the relatively low cleaning member 21 is lower than the conveying surface 13, the brush 23 provided on the cleaning member 21 can extend to or beyond the conveying surface 13.

[0056] Such a design facilitates the workpiece to enter the cleaning channel 24 smoothly, so that the dust removal operation can be carried out stably.

[0057] According to some embodiments of the present application, optionally, please refer to Figure 2 The brushes 23 include a plurality of brushes, all of which are sequentially distributed along the length direction Z of the cleaning member 21 to form a cleaning area 231 , and the suction nozzle 22 is disposed on at least one side of the cleaning area 231 along the conveying direction X of the conveying mechanism 10 .

[0058] The cleaning area 231 refers to a structure formed by a plurality of brushes 23 spaced apart along the length direction Z of the cleaning member 21, which can increase the cleaning range of the brushes 23 on the workpiece. In the conveying direction X, the suction nozzle 22 can be arranged at the upstream end of the cleaning area 231, or at the downstream end; or, at the same time, at opposite sides of the cleaning area 231.

[0059] When the suction nozzle 22 is set at the downstream end of the cleaning area 231, the workpiece can first contact the brush 23 and scrape off the dust on the surface; then pass through the position where the suction nozzle 22 is located, so that the scraped dust is sucked into the suction nozzle 22. When the suction nozzle 22 is set at the upstream end of the cleaning area 231, the workpiece first passes through the position where the suction nozzle 22 is located, sucks on the surface of the workpiece, and sucks away some dust; then moves to contact the brush 23 to scrape off the dust. Since the suction nozzle 22 is set close to the brush 23, the scraped dust will also enter the suction nozzle 22 under the suction force.

[0060] In some examples, the suction nozzles 22 are disposed on opposite sides of the cleaning area 231 along the conveying direction X of the conveying mechanism 10 . Meanwhile, on either side of the cleaning area 231 along the conveying direction X, the suction nozzles 22 include a plurality of suction nozzles 22 , all of which are distributed along the length direction Z of the cleaning member 21 .

[0061] With such a design, the cleaning area 231 formed can increase the cleaning range of the brush 23 on the workpiece and improve the dust removal effect; at the same time, the brush 23 and the suction nozzle 22 act on the workpiece in sequence, which is conducive to further improving the dust removal effect.

[0062] According to some embodiments of the present application, optionally, please refer to Figure 2 The cleaning member 21 has a suction channel 211 in communication with the suction nozzle 22 , and the suction channel 211 is used to communicate with the suction device.

[0063] The suction channel 211 refers to the space inside the cleaning member 21. When the suction nozzle 22 sucks dust, the dust will enter the suction channel 211 and be discharged by the suction channel 211. The suction channel 211 can extend linearly along the length direction Z of the cleaning member 21, or can extend in a curve.

[0064] Such a design allows the dust sucked by the suction nozzle 22 to directly enter the interior of the cleaning member 21, further reducing the probability of dust diffusion, which is beneficial to improving the cleanliness of the site and the service life of the equipment.

[0065] According to some embodiments of the present application, optionally, please refer to Figure 2 The cleaning mechanism 20 also includes a connector 212, which is connected to the suction channel 211 and is used to connect to the suction device.

[0066] The connector 212 can be arranged at one end of the cleaning member 21, or at the middle of the cleaning member 21. At the same time, there are many ways of connection between the connector 212 and the cleaning member 21, such as but not limited to threaded connection, clamping, welding, bonding, etc.

[0067] When the cleaning members 21 are connected end to end and the suction channels 211 are connected in sequence, a joint 212 may be provided on the first or last cleaning member 21 .

[0068] With such a design, the joint 212 is introduced to facilitate the connection between the suction device and the suction channel 211, thereby improving the assembly efficiency of the device.

[0069] According to some embodiments of the present application, optionally, please refer to Figure 1 The cleaning mechanism 20 also includes a collecting box 40 , which is used to receive the dust discharged from the suction channel 211 .

[0070] The collecting box 40 is used to collect dust, and its shape can be designed into regular shapes such as a cube, a cuboid, a cylinder, etc.; it can also be designed into an irregular shape. When connected to the suction channel 211, the suction channel 211 can be connected to the inlet of the collecting box 40 through a pipe; and then the outlet of the collecting box 40 is connected to the suction device through a pipe. In order to reduce the dust entering the suction device, a filter can be set at the outlet.

[0071] With such a design, the collection box 40 is introduced to effectively collect the dust, making it easier to uniformly process the collected dust.

[0072] According to some embodiments of the present application, optionally, please refer to Figure 1 The cleaning mechanisms 20 include more than two, and all the cleaning mechanisms 20 are distributed in sequence along the conveying direction X of the conveying mechanism 10.

[0073] When the cleaning mechanism 20 has a cleaning channel 24 , each cleaning mechanism 20 is sequentially distributed in the conveying direction X. At this time, the workpiece passes through each cleaning channel 24 sequentially under the drive of the conveying mechanism 10 .

[0074] The number of cleaning mechanisms 20 may not be limited to Figure 1 The number of cleaning mechanisms 20 may be two, or other numbers, such as three, four, etc. Taking two cleaning mechanisms 20 as an example, when the workpiece comes out of the kiln, it flows through the first cleaning mechanism 20. At this time, the brush 23 is tightly fitted with the workpiece. During the conveying process of the workpiece, a relative friction state is formed between the brush 23 and the workpiece. The relative friction between the brush 23 and the workpiece is used to automatically clean the powder bonded to the side wall and the bowl cover. The dust generated during the cleaning process has not yet spread to the surroundings, and is promptly absorbed by the suction nozzle 22 around the brush 23 (cleaning and dust absorption are performed simultaneously). Similarly, when the workpiece moves to the second cleaning mechanism 20, the workpiece is cleaned again in the same way. In this process, the passage and rhythm of the workpiece are not affected, which not only ensures the cleanliness of the site and equipment, but also ensures the production rhythm. At the same time, it can reduce the probability of this part of dust mixing into the finished powder, entering the kiln again to cause chemical reactions and affecting the consistency of the finished powder.

[0075] With such a design, the cleaning mechanisms 20 are distributed in sequence along the conveying direction X, so that the workpiece can be cleaned at least twice, which greatly improves the cleaning force and the dust removal effect.

[0076] According to some embodiments of the present application, optionally, please refer to Figure 1 The cleaning and dust removing device 100 further includes a connecting piece 30 , and a connecting piece 30 is connected between two adjacent cleaning mechanisms 20 .

[0077] The connection method of the connecting member 30 between the two cleaning mechanisms 20 can be but not limited to welding, bolt connection, clamping, riveting, welding, etc. At the same time, the number of the connecting member 30 can be one or more, for example: multiple connecting members 30 are connected between two adjacent cleaning mechanisms 20.

[0078] With such a design, the connecting member 30 is introduced, so that two adjacent cleaning mechanisms 20 are stably connected, thereby enabling the cleaning mechanism 20 to operate stably on the conveying mechanism 10 .

[0079] According to some embodiments of the present application, optionally, please refer to Figure 1 The conveying mechanism 10 includes a support frame 11 and a plurality of conveying rollers 12 rotatably disposed on the support frame 11 . All the conveying rollers 12 are arranged in parallel and spaced apart along a conveying direction X of the conveying mechanism 10 . The cleaning mechanism 20 is disposed on the support frame 11 .

[0080] During the cleaning process, the conveying roller 12 rotates around its own axis under the action of the motor, driving the workpiece to move forward and contact with the brush 23 to achieve effective cleaning.

[0081] Such a design allows the workpiece to be transported stably; at the same time, a stable contact with the brush 23 is achieved, thereby achieving effective cleaning.

[0082] According to some embodiments of the present application, the present application provides a battery production system, and the battery production system includes any one of the above cleaning and dust removal devices 100.

[0083] According to some embodiments of this application, please refer to Figure 1 and Figure 2 The present application provides a cleaning and dust removal device 100, including two cleaning mechanisms 20 and a conveying mechanism 10. The two cleaning mechanisms 20 are arranged in parallel, and the cleaning mechanism 20 includes a brush 23 with a suction nozzle 22, and the brush 23 has a ring structure. The first brush 23 with a suction nozzle 22 performs the initial cleaning of the outer side of the sagger. During the cleaning process, the generated dust is directly sucked by the suction nozzle 22 of the brush 23 and collected into the collection box 40. Similarly, the second-stage brush 23 with a suction nozzle 22 uses the same method for cleaning. The two-time cleaning and dust removal can effectively clean the dust on the outer wall of the sagger, improve the cleanliness of the site and equipment, and reduce the probability of this part of the powder being mixed into the finished powder. At the same time, it reduces the hidden danger of the powder re-entering the kiln to cause chemical reactions that affect the consistency of the finished powder.

[0084] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
