[0003] Summary of the Invention

[0004] Some embodiments of the present application provide a cleaning device, a cleaning method, and a battery production system to alleviate the problem of low cleaning efficiency.

[0005] Some embodiments of the present application provide a cleaning device, comprising: a cleaning assembly including two cleaning parts arranged opposite to each other, wherein a space is formed between the two cleaning parts to accommodate items to be cleaned; and a first driving assembly configured to drive the cleaning assembly to move so as to clean both sides of at least two items to be cleaned arranged in sequence.

[0006] The cleaning assembly includes two cleaning parts arranged opposite to each other. The first driving assembly drives the cleaning assembly to move. The two cleaning parts arranged opposite to each other can clean both sides of at least two items to be cleaned arranged in sequence during the movement. It has a high degree of automation and high cleaning efficiency, which is conducive to realizing continuous production functions and meeting the production rhythm of the battery production system.

[0007] In some embodiments, the cleaning device further comprises a sensor provided on the cleaning component, wherein the sensor is configured to detect the distance between the cleaning element and the item to be cleaned.

[0008] During the cleaning process, the sensor detects the distance between the cleaning piece and the items to be cleaned in real time. The distance value detected by the sensor can be used to determine whether the distance between the cleaning piece and the items to be cleaned is too close or too far, thereby alleviating the problem of the cleaning piece and the items to be cleaned touching each other and damaging the items to be cleaned due to the distance between the cleaning piece and the items to be cleaned being too close, and alleviating the problem of reduced cleaning effect due to the distance between the cleaning piece and the items to be cleaned being too far.

[0009] In some embodiments, the sensor comprises a laser sensor.

[0011] In some embodiments, the cleaning device also includes a controller, which is electrically connected to the sensor and the first drive component respectively. The controller is configured to receive the detection distance value of the sensor and compare it with a preset distance value therein. When the detection distance value is less than or equal to the preset distance value, the first drive component is controlled to stop working.

[0012] During the cleaning process, the sensor detects the distance between the cleaning element and the items to be cleaned in real time, and sends the detected distance value to the controller. After receiving the detected distance value of the sensor, the controller compares the detected distance value with a preset distance value therein. When the detected distance value is less than or equal to the preset distance value, the first drive component can be controlled to stop working. The degree of automation is high, the first drive component no longer drives the cleaning component to move, and the cleaning component stops cleaning. Therefore, it can alleviate the problem that the cleaning element and the items to be cleaned touch each other due to the distance between the cleaning element and the items to be cleaned being too close, causing the items to be cleaned to be damaged.

[0013] In some embodiments, the cleaning device further includes an adjusting component configured to adjust the distance between the two cleaning parts.

[0014] The adjustment component can adjust the distance between the two cleaning parts according to the size of the items to be cleaned, so as to be suitable for cleaning items of different sizes and facilitate the replacement of items to be cleaned.

[0021] In some embodiments, the cleaning device further comprises a sensor provided on the cleaning component, wherein the sensor is configured to detect the distance between the cleaning element and the object to be cleaned along the third direction when the cleaning component moves along the first direction.

[0022] When the second driving assembly drives the cleaning assembly to move in the first direction and adjusts the position of the cleaning assembly on both sides of the items to be cleaned, the distance between the cleaning element and the items to be cleaned along the third direction is detected in real time by the sensor. The detected distance value of the sensor can be used to determine whether the distance between the cleaning element and the items to be cleaned is too close or too far, thereby alleviating the problem that the cleaning element and the items to be cleaned touch each other and damage the items to be cleaned due to the close distance between the cleaning element and the items to be cleaned, and alleviating the problem that the cleaning effect is reduced due to the long distance between the cleaning element and the items to be cleaned.

[0063] With the vigorous promotion of new energy vehicles, new energy batteries have been widely developed. To improve battery assembly efficiency, all battery assembly tasks are generally performed on an assembly line. The battery assembly process involves stacking multiple battery cells in a housing, and the cells need to be cleaned and coated with glue before stacking. In some related technologies, the battery cell cleaning process is carried out using decentralized workstations and operators working together, lacking continuous production capabilities. Not only is the cleaning efficiency low, but it is also highly dependent on operators, which to some extent is not conducive to the quality control of battery cell products.

[0064] Based on this, some embodiments of the present application provide a cleaning device, a cleaning method and a battery production system to alleviate the problem of low cleaning efficiency of battery cells.

[0065] Referring to Figure 1, in some embodiments, the battery 300 of the present application includes a shell assembly 301 and at least one battery cell 101. The interior of the shell assembly 301 is a hollow structure, and at least one battery cell 101 is accommodated in the shell assembly 301. The shell assembly 301 may include two parts, respectively referred to herein as a box 301a and a cover 301b. The box 301a and the cover 301b are arranged relative to each other and snap together to form a box with a closed chamber. At least one battery cell 101 includes more than two battery cells 101, and the multiple battery cells 101 can be connected in series, in parallel, or in mixed connection. Mixed connection refers to a mixture of series and parallel connection. After the multiple battery cells 101 are connected in parallel, in series, or in mixed connection, they are placed in a closed chamber formed by snapping together the box 301a and the cover 301b.

[0066] The battery 300 of the present application can be used in electrical devices and can provide electrical energy for the electrical devices. The electrical devices can be mobile phones, portable devices, laptop computers, electric vehicles, electric cars, ships, spacecraft, electric toys and electric tools. For example, spacecraft include airplanes, rockets, space shuttles and spacecraft. Electric toys include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys and electric airplane toys. Electric tools include metal cutting power tools, grinding power tools, assembly power tools and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators and electric planers.

[0067] The power-consuming device of the present application may be a vehicle, such as a new energy vehicle, which may be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. Alternatively, the power-consuming device may be a drone or a ship, etc.

[0068] 2 to 4 , some embodiments of the present application provide a cleaning device, comprising a cleaning assembly 1. The cleaning assembly 1 comprises two cleaning members 11 disposed opposite to each other. A space is formed between the two cleaning members 11 to accommodate an item 100 to be cleaned.

[0069] The cleaning device further comprises a first driving assembly 2, which is drivingly connected to the cleaning assembly 1. The first driving assembly 2 is configured to drive the cleaning assembly 1 to move so as to clean both sides of at least two sequentially arranged objects 100 to be cleaned.

[0070] The cleaning assembly 1 includes two cleaning parts 11 arranged opposite to each other. The first driving assembly 2 drives the cleaning assembly 1 to move. The two cleaning parts 11 arranged opposite to each other can clean both sides of at least two items to be cleaned 100 arranged in sequence during the movement. It has a high degree of automation and high cleaning efficiency, which is conducive to realizing continuous production functions and meeting the production rhythm of the battery production system.

[0071] In some embodiments, the cleaning device further includes a sensor 3 provided on the cleaning assembly 1 , and the sensor 3 is configured to detect the distance between the cleaning element 11 and the object 100 to be cleaned.

[0072] During the cleaning process, the sensor 3 detects the distance between the cleaning element 11 and the item 100 to be cleaned in real time. The distance value detected by the sensor 3 can be used to determine whether the distance between the cleaning element 11 and the item 100 to be cleaned is too close or too far, thereby alleviating the problem that the cleaning element 11 and the item 100 to be cleaned touch each other and damage the item 100 due to the distance between the cleaning element 11 and the item 100 being too close, and alleviating the problem that the cleaning effect is reduced due to the distance between the cleaning element 11 and the item 100 to be cleaned being too far.

[0073] In some embodiments, the sensor 3 includes a laser sensor 31 .

[0074] The laser sensor 31 uses laser ranging, which has high detection accuracy, can improve the foolproof effect during the cleaning process and improve product yield.

[0075] In some embodiments, the cleaning device further includes a controller 4. The controller 4 is electrically connected to the sensor 3 and the first drive assembly 2. The controller 4 is configured to receive the distance value detected by the sensor 3 and compare it with a preset distance value. If the detected distance value is less than or equal to the preset distance value, the controller 4 controls the first drive assembly 2 to stop operating. The cleaning assembly 1 stops moving and stops cleaning. The controller 4 adjusts the distance between the cleaning element 11 and the item to be cleaned 100 so that the distance between the cleaning element 11 and the item to be cleaned 100 is greater than the preset distance value.

[0076] During the cleaning process, the sensor 3 detects the distance between the cleaning element 11 and the article 100 to be cleaned in real time, and sends the detected distance value to the controller 4. After receiving the detected distance value of the sensor 3, the controller 4 compares the detected distance value with the preset distance value therein. When the detected distance value is less than or equal to the preset distance value, the first driving component 2 can be controlled to stop working. The degree of automation is high. The first driving component 2 no longer drives the cleaning component 1 to move, and the cleaning component 1 stops the cleaning operation. Therefore, the problem that the cleaning element 11 and the article 100 to be cleaned touch each other due to the distance between the cleaning element 11 and the article 100 being too close, causing the article 100 to be cleaned to be damaged, can be alleviated.

[0077] In some embodiments, the controller 4 is also electrically connected to the cleaning component 1. The controller 4 is configured to control the cleaning component 1 to start or stop the cleaning operation.

[0078] The controller 4 is configured to receive the detection distance value of the sensor 3 and compare it with the preset distance value therein. When the detection distance value is less than or equal to the preset distance value, the first drive component 2 is controlled to stop working, and the first drive component 2 no longer drives the cleaning component 1 to move, and the controller 4 also controls the cleaning component 1 to stop cleaning.

[0079] In some embodiments, the cleaning device further includes an adjusting component 5 , which is configured to adjust the distance between the two cleaning parts 11 .

[0080] The adjustment assembly 5 can adjust the distance between the two cleaning elements 11 according to the size of the items to be cleaned 100, so as to be suitable for cleaning items 100 of different sizes and facilitate the replacement of the items to be cleaned 100. In addition, by adjusting the distance between the two cleaning elements 11 by the adjustment assembly 5, the problem of the cleaning elements 11 being too close or too far from the items to be cleaned 100 can be alleviated.

[0081] In some embodiments, the cleaning device further comprises a second driving assembly 6. The second driving assembly 6 is configured to drive the cleaning assembly 1 to move along the first direction X.

[0082] The first direction X intersects the second direction Y and the third direction Z respectively; the second direction Y is parallel to the arrangement direction of at least two items to be cleaned 100; and the third direction Z is parallel to the arrangement direction of the two cleaning parts 11.

[0083] In some embodiments, the first direction X is perpendicular to the second direction Y and the third direction Z, respectively, and the second direction Y is perpendicular to the third direction Z. Optionally, the first direction X is parallel to the vertical direction, and the second direction Y and the third direction Z are located in a horizontal plane.

[0084] The second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X, and can adjust the position of the cleaning assembly 1 on both sides of the object to be cleaned 100 so that the cleaning assembly 1 reaches the cleaning position and both sides of the object to be cleaned 100 can be completely cleaned.

[0085] In some embodiments, the second driving component 6 drives the cleaning component 1 to move along the first direction X, so that the cleaning component 1 is located in the upper cleaning position on both sides of the item to be cleaned 100, and the upper areas on both sides of the item to be cleaned 100 are cleaned. After the upper areas on both sides of the item to be cleaned 100 are cleaned, the second driving component 6 drives the cleaning component 1 to move along the first direction X, so that the cleaning component 1 is located in the lower cleaning position on both sides of the item to be cleaned 100, and the lower areas on both sides of the item to be cleaned 100 are cleaned.

[0086] Of course, the second driving assembly 6 is not limited to adjusting the position of the cleaning assembly 1 to the upper and lower cleaning positions on both sides of the article to be cleaned 100. In the event that the article to be cleaned 100 is too large in the first direction X, the article to be cleaned 100 can be divided into three or more cleaning positions along the first direction X. The second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X, so that the cleaning assembly 1 is sequentially positioned at each cleaning position on both sides of the article to be cleaned 100, so that both sides of the article to be cleaned 100 can be completely cleaned.

[0087] In some embodiments, the first driving assembly 2 is drivingly connected to the second driving assembly 6 so that the second driving assembly 6 moves along the second direction Y, and the second driving assembly 6 is connected to the cleaning assembly 1.

[0088] The first drive assembly 2 drives the second drive assembly 6 to move along the second direction Y. The second drive assembly 6 is connected to the cleaning assembly 1 and is further capable of driving the cleaning assembly 1 to move along the second direction Y, so that the cleaning assembly 1 cleans both sides of at least two items 100 to be cleaned that are sequentially arranged along the second direction Y. The second drive assembly 6 is also capable of driving the cleaning assembly 1 to move along the first direction X, and is capable of adjusting the position of the cleaning assembly 1 on both sides of the items 100 to be cleaned, so that the cleaning assembly 1 reaches the cleaning position and both sides of the items 100 to be cleaned are completely cleaned.

[0089] In some embodiments, the cleaning device further includes an adjusting assembly 5 , which connects the second driving assembly 6 and the cleaning assembly 1 , and is configured to adjust the distance between the two cleaning members 11 along the third direction Z.

[0090] The adjustment assembly 5 can adjust the distance between the two cleaning elements 11 along the third direction Z according to the size of the items to be cleaned 100, thereby being suitable for cleaning items 100 of different sizes and facilitating the replacement of the items to be cleaned 100. Furthermore, adjusting the distance between the two cleaning elements 11 along the third direction Z by the adjustment assembly 5 can alleviate the problem of the cleaning elements 11 being too close or too far from the items to be cleaned 100. The adjustment assembly 5 is also connected to the second drive assembly 6. The second drive assembly 6 can drive the cleaning assembly 1 along the first direction X through the adjustment assembly 5, while the first drive assembly 2 can drive the second drive assembly 6 along the second direction Y, thereby driving the cleaning assembly 1 along the second direction Y. The entire structure is compact, capable of adjusting the position of the cleaning assembly 1 in the first direction X and moving it in the second direction Y, and capable of adjusting the distance between the two cleaning elements 11 along the third direction Z.

[0091] In some embodiments, the cleaning device further comprises a sensor 3 provided on the cleaning assembly 1. The sensor 3 is configured to detect the distance between the cleaning element 11 and the object to be cleaned 100 along the third direction Z when the cleaning assembly 1 moves along the first direction X.

[0092] When the second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X and adjusts the position of the cleaning assembly 1 on both sides of the article to be cleaned 100, the sensor 3 detects in real time the distance between the cleaning element 11 and the article to be cleaned 100 along the third direction Z. The distance value detected by the sensor 3 can be used to determine whether the distance between the cleaning element 11 and the article to be cleaned 100 is too close or too far, thereby alleviating the problem that the cleaning element 11 and the article to be cleaned 100 touch each other and damage the article to be cleaned due to the distance between the cleaning element 11 and the article to be cleaned 100 being too close, and alleviating the problem that the cleaning effect is reduced due to the distance between the cleaning element 11 and the article to be cleaned 100 being too far.

[0093] In some embodiments, the cleaning device further includes a controller 4. Controller 4 is electrically connected to sensor 3 and second drive assembly 6. Controller 4 is configured to receive a detected distance value from sensor 3 and compare it with a preset distance value within the controller.

Cleaning assembly 1 stops moving and adjusts the distance between cleaning element 11 and item 100 to a value greater than the preset distance value.

[0094] When the second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X and adjusts the position of the cleaning assembly 1 on both sides of the article to be cleaned 100, the distance between the cleaning element 11 and the article to be cleaned 100 is detected in real time by the sensor 3, and the detected distance value is sent to the controller 4. When the detected distance value of the sensor 3 received is less than or equal to the preset distance value therein, the controller 4 can control the second driving assembly 6 to stop working, with a high degree of automation. The second driving assembly 6 no longer drives the cleaning assembly 1 to move, thereby alleviating the problem that the cleaning element 11 and the article to be cleaned 100 touch each other due to the distance between them being too close, thereby damaging the article to be cleaned 100.

When the telescopic member 84 is extended and pushes the support plate 81, the height of the support plate 81 can be made higher than the height of the conveying member 9, and then the supporting member 200 can be pushed up and separated from the two conveying members 9.

[0111] The supporting member 200 carries at least two items to be cleaned 100 arranged in sequence. After being sent to the cleaning position of the cleaning device through two conveying members 9, the telescopic member 84 drives the support plate 81 to lift and push the supporting member 200 to separate the supporting member 200 from the two conveying members 9, which can prevent the wear of the conveying members 9 during the cleaning process of the items to be cleaned 100.

[0128] Some embodiments of the present application further provide a cleaning method for the cleaning device in any of the above embodiments, comprising the following steps:

[0129] The cleaning assembly 1 is driven to move by the first driving assembly 2 , and the two cleaning components 11 of the cleaning assembly 1 clean both sides of at least two sequentially arranged objects 100 to be cleaned.

[0130] The cleaning device drives the cleaning component 1 to move through the first driving component 2. The two cleaning parts 11 arranged opposite to each other can clean both sides of at least two items to be cleaned 100 arranged in sequence during the movement. It has a high degree of automation and high cleaning efficiency, which is conducive to realizing continuous production functions and meeting the production rhythm of the battery production system.

[0131] In some embodiments, the cleaning device further comprises a sensor 3 provided on the cleaning component 1. The cleaning method further comprises:

[0132] During the process of the two cleaning elements 11 cleaning both sides of at least two sequentially arranged articles to be cleaned 100, the distance between the cleaning elements 11 and the articles to be cleaned 100 is detected by the sensor 3. When the distance value detected by the sensor 3 is less than or equal to a preset distance value, the first driving assembly 2 is controlled to stop working.

[0133] During the cleaning process, the sensor 3 detects the distance between the cleaning element 11 and the item 100 to be cleaned in real time. The distance value detected by the sensor 3 can be used to determine whether the distance between the cleaning element 11 and the item 100 to be cleaned is too close or too far. When the distance value detected by the sensor 3 is less than or equal to the preset distance value, the first driving component 2 is controlled to stop working, and the first driving component 2 no longer drives the cleaning component 1 to move, and the cleaning component 1 stops cleaning. Therefore, it can alleviate the problem that the cleaning element 11 and the item 100 to be cleaned touch each other due to the distance between the cleaning element 11 and the item 100 being too close, causing the item 100 to be cleaned to be damaged.

[0134] In some embodiments, the cleaning device further comprises a second drive assembly 6. The cleaning method further comprises:

[0135] Before the first driving assembly 2 drives the cleaning assembly 1 to move, the second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X, so that the two cleaning elements 11 are located on both sides of the object to be cleaned 100, and the positions of the two cleaning elements 11 in the first direction X are adjusted.

[0136] The first direction X intersects the second direction Y and the third direction Z respectively. The second direction Y is parallel to the arrangement direction of at least two items to be cleaned 100 . The third direction Z is parallel to the arrangement direction of the two cleaning elements 11 .

[0137] The second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X, and can adjust the position of the cleaning assembly 1 on both sides of the object to be cleaned 100 so that the cleaning assembly 1 reaches the cleaning position and both sides of the object to be cleaned 100 can be completely cleaned.

[0138] In some embodiments, the cleaning device further comprises a sensor 3 provided on the cleaning component 1. The cleaning method further comprises:

[0139] When the second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X, the sensor 3 detects the distance between the cleaning element 11 and the object to be cleaned 100 along the third direction Z. When the distance value detected by the sensor 3 is less than or equal to a preset distance value, the second driving assembly 6 is controlled to stop working.

[0140] When the second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X and adjusts the position of the cleaning assembly 1 on both sides of the article to be cleaned 100, the sensor 3 detects in real time the distance between the cleaning element 11 and the article to be cleaned 100 along the third direction Z. When the detected distance value of the sensor 3 is less than or equal to the preset distance value, the second driving assembly 6 is controlled to stop working and the second driving assembly 6 no longer drives the cleaning assembly 1 to move. Therefore, the problem of the cleaning element 11 and the article to be cleaned 100 contacting with each other due to the distance between them being too close, thereby reducing the problem of damage to the article to be cleaned 100.

[0141] In some embodiments, a cleaning method for a cleaning device comprises the following steps:

[0142] The items to be cleaned 100 are transported to the cleaning device by the conveying device and are sent to the conveying member 9. After the items to be cleaned 100 arrive at the cleaning position, the telescopic member 84 drives the support plate 81 to lift and push the supporting member 200, so that the supporting member 200 is separated from the two conveying members 9 and is connected to the supporting member 200 through the positioning member 82, so that the supporting member 200 can be positioned; the second driving assembly 6 drives the cleaning assembly 1 to move along the first direction X, so that the cleaning assembly 1 is located at the upper cleaning position on both sides of the items to be cleaned 100, and the first driving assembly 2 drives the cleaning assembly 1 to move along the second direction Y. During the movement process, the two cleaning members 11 arranged opposite to each other are moved. The cleaning assembly 1 can clean the upper halves of at least two sequentially arranged items 100. After cleaning the upper halves of the items 100, the second drive assembly 6 drives the cleaning assembly 1 to move in a first direction X, positioning the cleaning assembly 1 at the lower cleaning position on both sides of the items 100. The first drive assembly 2 drives the cleaning assembly 1 in a direction opposite to the second direction Y. During this movement, the two opposing cleaning elements 11 can clean the lower halves of at least two sequentially arranged items 100. Whether the second drive assembly 6 drives the cleaning assembly 1 in the first direction X or the first drive assembly 2 drives the cleaning assembly 1 in the second direction Y, the sensor 3 detects the distance between the cleaning element 11 and the items 100 in real time. When the detected distance value is less than or equal to a preset distance value, the cleaning assembly 1 is controlled to stop moving. This alleviates the problem of the cleaning element 11 and the items 100 being too close to each other, causing the cleaning element 11 to contact the items 100 and damage the items 100.

[0143] Referring to Figures 2 to 12, in some specific embodiments, during the plasma cleaning process, a laser sensor 31 is used to detect in real time the distance between the plasma cleaning component 111 and the battery cell 101 to be cleaned. If the detected distance value is less than the preset distance value of the laser ranging, the plasma cleaning component 111 is stopped from igniting and the plasma cleaning is interrupted to prevent the plasma cleaning component 111 from colliding with the battery cell 101 and avoid damage to the battery cell blue film. The system is compatible with battery cells of different sizes.

[0144] The distance between the two plasma cleaning parts 111 can be flexibly adjusted according to the size of the battery cell, so that plasma cleaning of battery cells of different sizes can be achieved, and the replacement is convenient.

[0145] The support assembly 8 is used to lift and position the battery cell 101. The support assembly 8 positions the support member 200 carrying at least two battery cells 101 flowing in by the double-speed chain (conveyor device). The at least two battery cells 101 carried by the support member 200 are referred to as the module to be cleaned.

[0146] In some specific embodiments, the cleaning method of the cleaning device includes the following steps.

[0147] The module to be cleaned flows into the plasma cleaning station of the cleaning device, and is lifted and positioned by the support plate 81 of the support assembly 8 .

[0148] The laser sensor 311 measures the distance between the module to be cleaned and the two sides and the cleaning element 11 .

[0149] The first driving component 2 drives the plasma cleaning component 11 to move forward to clean the upper half of the two sides of the battery cell. During the cleaning process, the laser sensor 311 detects the distance between the plasma cleaning component 111 and the battery cell 101 in real time. When the detected distance value is less than or equal to the preset distance value, the driving of the first driving component 2 is stopped and the plasma cleaning component 111 stops firing.

[0150] After the upper half of the two side surfaces of the battery cell are cleaned, the second drive component 6 drives the cleaning component 1 to move downward to the lower cleaning position, and the first drive component 2 drives the plasma cleaning component 11 to move backward to clean the lower half of the two side surfaces of the battery cell. During the cleaning process, the laser sensor 31 detects the distance between the plasma cleaning component 111 and the battery cell 101 in real time. When the detected distance value is less than or equal to the preset distance value, the driving of the first drive component 2 is stopped and the plasma cleaning component 111 is stopped from firing.

[0151] The support plate 81 of the support assembly 8 descends, releasing the module to be cleaned after plasma cleaning, and the module to be cleaned flows out.

[0152] The above steps are executed in a loop to complete the cleaning of multiple modules to be cleaned.

[0153] In some specific embodiments, the cleaning device uses a laser sensor ranging method to measure the distance between the plasma cleaning part and the battery cell. By setting the laser ranging measurement value, it can adapt to battery cells of different sizes. The model change is convenient and reliable, the detection accuracy is high, the plasma cleaning process has a good anti-mistake effect, and the product yield is improved.

[0154] Some embodiments of the present application further provide a battery production system, comprising a battery cell providing device and the cleaning device of any of the above embodiments, wherein the object 100 to be cleaned comprises a battery cell 101 provided by the battery cell providing device.

[0155] The battery production system includes the cleaning device in any of the above embodiments and accordingly has the beneficial effects of the cleaning device.

[0156] In some embodiments, the at least two battery cells 101 provided by the battery cell providing device are arranged sequentially, and the at least two battery cells 101 are placed on a carrier 200 as a group of modules to be cleaned and fed into the cleaning device. The arrangement of the at least two battery cells 101 in the cleaning device can be consistent with the arrangement of the at least two battery cells 101 within the housing assembly 301 of the battery 300. After being cleaned in the cleaning device, the at least two battery cells 101 can remain in the housing assembly 301 without changing their arrangement, thereby improving production efficiency.

[0157] In some embodiments, at least two battery cells 101 are arranged in a large-surface bonding manner.

[0158] In some embodiments, the at least two battery cells 101 include two, three, four, five, ..., ten battery cells or more than ten battery cells, etc. The specific number of battery cells 101 included in the battery 300 can be set according to the battery specification requirements.
