Description

Technical Field

[0001] This application relates to the field of lithium battery processing technology, and in particular to a cleaning device. Background Technology

[0002] In the lithium battery manufacturing process, the positive electrode sheet, negative electrode sheet and separator are first stacked in a stacking machine to form a stacked structure. Then, the stacked structure is wound, the tabs are welded, the casing is installed and the electrolyte is injected to make a battery cell.

[0003] In the stacking process, the robot arm picks up the electrode sheets from the material frame and places them on the platform of the inspection station. The inspection device checks the size, angle and other parameters of the electrode sheets. If the size or angle of the electrode sheet is not up to standard, or if the inspection device detects that there are multiple electrode sheets on the platform, the electrode sheets on the platform are determined to be unqualified electrode sheets (NG electrode sheets). At this time, the cleaning device needs to scrape the NG electrode sheets off the platform.

[0004] Typically, during the scraping process, the detection device blows air onto the NG electrode to separate it from the platform, and then the cleaning device's brush scrapes the NG electrode off the platform. This method has strict requirements on airflow speed. If the airflow speed is too low, it is difficult for the brush to scrape the electrode; if the airflow speed is too high, there is a risk that the NG electrode will shift and the brush will become ineffective, resulting in the need to manually remove the NG electrode from the platform, which affects the efficiency of the stacking process.

[0007] In this application, the scraper can generate a large pushing force on the electrode sheets on the platform, thereby improving the cleaning efficiency of the cleaning device on the NG electrode sheets on the platform, reducing the risk of long cleaning cycles caused by manual handling of NG electrode sheets, and thus shortening the platform's cleaning cycle. This facilitates improved efficiency of the stacking process and shortens the overall processing cycle of lithium batteries. By cleaning dust off the platform with the cleaning component, the risk of dust adhering to the electrode surface and causing damage to the electrode sheets or even the lithium batteries is reduced, thereby improving the processing yield of lithium batteries. In addition, the cleaning component can achieve self-cleaning of the platform surface, thereby reducing the difficulty of manual cleaning and shortening the platform's cleaning cycle, which further improves the efficiency of the stacking process and shortens the processing cycle of lithium batteries.

[0013] In one possible design, there are multiple cleaning components distributed along the length of the cleaning device; along the length of the cleaning device, a cleaning channel is located between two adjacent cleaning components, and the cleaning channel can simultaneously inject cleaning fluid into two adjacent cleaning components.

[0014] In one possible design, the housing includes a partition that divides the inner cavity into a first cavity and a second cavity along the height direction of the cleaning device.

[0031] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0032] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0033] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0034] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0035] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0036] This application provides a cleaning device, such as... Figure 1As shown, the cleaning device includes a housing 1, a scraper 2 installed on the housing 1, and a cleaning component 3 installed on the housing 1. The scraper 2 is used to scrape away the target object on the platform. The target object includes, but is not limited to, NG electrode sheets, tabs, films, etc. In this embodiment, the target object is an NG electrode sheet. The cleaning component 3 is used to remove dust from the platform.

[0037] In this embodiment, the scraper 2 can generate a large pushing force on the electrode sheets on the platform, thereby improving the cleaning efficiency of the cleaning device on the NG electrode sheets on the platform, reducing the risk of long cleaning cycles caused by manual handling of NG electrode sheets, and thus shortening the platform cleaning cycle. This facilitates the improvement of the efficiency of the stacking process and the shortening of the overall lithium battery processing cycle. The cleaning component 3 cleans the dust on the platform, reducing the risk of dust adhering to the electrode surface and causing damage to the electrode sheets or even the lithium battery, thereby improving the lithium battery processing yield. Furthermore, the cleaning component 3 can achieve self-cleaning of the platform surface, thereby reducing the difficulty of manual cleaning and shortening the platform cleaning cycle, further improving the efficiency of the stacking process and shortening the lithium battery processing cycle.

[0038] Among them, such as Figure 1 As shown, a rubber strip 21 is installed on the scraper 2. The rubber strip 21 is used to contact the platform and scrape the electrode sheet away from the platform. By having the rubber strip 21 contact the platform, the contact force between the scraper 2 and the platform can be increased, thereby improving the cleaning efficiency of the scraper 2 on the NG electrode sheet on the platform. At the same time, the soft contact between the rubber strip 21 and the platform also reduces the risk of the scraper 2 damaging the platform.

[0039] In addition, the cleaning component 3 can be equipped with a cleaning cloth, cleaning cotton, brush 31, etc., to facilitate cleaning of the platform surface. In the embodiments of this application, such as... Figure 1 As shown, a brush 31 is installed on the cleaning component 3.

[0040] like Figure 1 As shown, the scraper 2 extends along the length direction X of the cleaning device, and the scraper 2 and the cleaning component 3 are distributed along the width direction Y of the cleaning device. When the cleaning device scrapes away the NG electrode on the platform, the scraper 2 contacts the platform, and the cleaning device moves along the width direction Y to scrape away the NG electrode on the platform.

[0041] like Figure 2 and Figure 3 As shown, the cleaning device includes a first driving member 4, which is driven to the cleaning member 3. The first driving member 4 can drive the cleaning member 3 to rotate to agitate the dust on the platform. The housing 1 has an inner cavity 11 and is provided with an adsorption hole (not shown in the figure). The inner cavity 11 is connected to the outside through the adsorption hole. The cleaning device also includes an adsorption member (not shown in the figure), which is connected to the inner cavity 11 and is used to adsorb dust through the inner cavity 11 and the adsorption hole.

[0042] In this embodiment, during the operation of the cleaning device, the first driving member 4 drives the cleaning member 3 to rotate around the height direction Z of the cleaning device, causing the dust on the platform to be stirred and floated up. Subsequently, the adsorption member causes a negative pressure to be generated in the inner cavity 11. Under the action of the adsorption member and the negative pressure, the stirred-up dust enters the inner cavity 11 through the adsorption hole and is drawn out of the inner cavity 11 by the adsorption member for collection, thereby removing the dust from the platform.

[0043] In this embodiment, the dust stirred up by the cleaning component 3 is collected by the adsorption component, reducing the risk of dust falling back onto the platform surface, thereby improving the cleaning performance of the cleaning device.

[0044] like Figure 2 and Figure 3 As shown, an adsorption pipe 12 is provided inside the inner cavity 11. Along the length direction X of the cleaning device, the adsorption pipe 12 passes through the inner cavity 11. The adsorption pipe 12 is connected to the adsorption element. The adsorption pipe 12 is provided with at least one through hole. The inner cavity 11 is connected to the adsorption pipe 12 through the through hole.

[0045] In this embodiment, the adsorption pipe 12 extends through the inner cavity 11. The adsorption element can be disposed at one or both ends of the adsorption pipe 12. The adsorption element draws air from the adsorption pipe 12, and the adsorption pipe 12 adsorbs air from the inner cavity 11 through the through holes. The inner cavity 11 draws in outside air through the adsorption holes, thereby sucking in and collecting dust stirred up from the outside into the adsorption element. By providing an adsorption pipe 12 that extends through the inner cavity 11 along the length X of the cleaning device, the risk of the adsorption element having a stronger adsorption force on one side of the inner cavity 11 and a weaker adsorption force on the other side is reduced, thereby improving the consistency of the adsorption force of the adsorption element on dust on both sides.

[0046] like Figure 2 and Figure 3 As shown, the housing 1 is provided with a liquid injection port 13, and the cleaning device also includes a cleaning channel 14. Along the height direction Z of the cleaning device, one end of the cleaning channel 14 is connected to the outside through the liquid injection port 13, and the other end of the cleaning channel 14 extends to the side of the housing 1 away from the liquid injection port 13. The cleaning channel 14 is used to inject cleaning fluid into the cleaning component 3.

[0047] In this embodiment, the cleaning channel 14 injects cleaning fluid into the cleaning component 3, so that the cleaning component 3 wipes the platform surface during rotation, thereby improving the cleaning effect of the cleaning device on the platform.

[0048] like Figure 2 and Figure 3 As shown, the cleaning device also includes a first switch assembly 5, which is used to block or open the cleaning channel 14.

[0049] In this embodiment, a first switch component 5 is provided, which can periodically block or open the cleaning channel 14, so that the platform is cleaned with cleaning fluid at a preset time or number of times, thereby reducing the consumption rate of cleaning fluid by the cleaning device and thus reducing the cleaning cost of the platform by the cleaning device.

[0050] In one embodiment, the first switching component 5 can be a common solenoid valve.

[0051] In another embodiment, such as Figure 2 and Figure 3 As shown, the first switch assembly 5 includes a first blocking member 51 and a second driving member 52. At least a portion of the first blocking member 51 is located within the cleaning channel 14. The second driving member 52 is driven to the first blocking member 51 and can drive the first blocking member 51 to rotate so that the first blocking member 51 abuts against the cleaning channel 14 or has a gap.

[0052] In this embodiment, the cleaning channel 14 is opened or blocked by the rotation of the first blocking member 51 driven by the second driving member 52, which simplifies the structure of the first switching assembly 5 and reduces the cost of the first switching assembly 5 and the cleaning device.

[0053] The outline of the first sealing element 51 matches the internal outline of the cleaning pipe. For example, if the internal outline of the cleaning pipe is circular, then the outline of the first sealing element 51 is also circular, so that the first sealing element 51 can block the cleaning pipe.

[0054] In one embodiment, the first sealing element 51 is a circular plate structure, and the second driving element 52 is directly connected to the circular plate structure to simplify the structure of the first sealing element 51 and reduce the cost of the first sealing element 51.

[0055] In another embodiment, such as Figure 4 As shown, the first sealing member 51 includes a sealing part 511 and a connecting part 512. The sealing part 511 is located inside the cleaning pipe and has a circular plate structure. One end of the connecting part 512 is connected to the sealing part 511, and the other end of the connecting part 512 extends to the outside of the cleaning pipe and is driven to connect with the second driving member 52. The thickness of the sealing part 511 is smaller than the thickness of the connecting part 512.

[0056] In this embodiment, the circular sealing portion 511 with a smaller thickness is connected to the second driving member 52 through the connecting portion 512 with a larger thickness. This reduces the difficulty of connecting the second driving member 52 and the first sealing portion 51, thereby reducing the difficulty of installing and disassembling the first switch assembly 5, and thus helping to shorten the installation and maintenance cycle of the cleaning device. The sealing portion 511 is connected to the second driving member 52 through the connecting portion 512, and the connecting portion 512 is relatively large, which can increase the connection stability between the first sealing portion 51 and the second driving member 52, reduce the risk of damage to the first sealing portion 51 and separation between the first sealing portion 51 and the second driving member 52, thereby extending the service life of the first switch assembly 5 and improving the working stability and reliability of the first switch assembly 5.

[0057] like Figure 2 and Figure 3 As shown, there are multiple cleaning components 3, which are distributed along the length direction X of the cleaning device. In the length direction X of the cleaning device, the cleaning channel 14 is located between two adjacent cleaning components 3, and the cleaning channel 14 can inject cleaning liquid into two adjacent cleaning components 3 at the same time.

[0058] In this embodiment, a cleaning channel 14 can simultaneously inject cleaning fluid into two adjacent cleaning components 3, thereby reducing the number of cleaning channels 14 required, simplifying the structure of the cleaning device, and reducing the cost of the cleaning device.

[0059] In one embodiment, the cleaning channel 14 extends through the inner cavity 11 along the height direction Z of the cleaning device, that is, one end of the cleaning channel 14 is directly connected to the liquid injection port 13, and the other end extends out of the housing 1.

[0060] In another embodiment, such as Figure 2 and Figure 3 As shown, the housing 1 includes a partition 15. Along the height direction Z of the cleaning device, the partition 15 divides the inner cavity 11 into a first cavity 111 and a second cavity 112. The first cavity 111 is connected to the outside through an adsorption hole, and the cleaning channel 14 is connected to the liquid injection port 13 through the second cavity 112. The second cavity 112 is used to store cleaning liquid.

[0061] In this embodiment, the second cavity 112 can store cleaning fluid, thereby reducing the number of times the cleaning device injects cleaning fluid, so as to simplify the operation of the cleaning device and improve the cleaning efficiency of the cleaning device.

[0062] like Figure 3As shown, the cleaning device also includes a second switch assembly 6, which is used to block or open the injection port 13. The second switch assembly 6 includes a second blocking member 61 and a third driving member 62. The third driving member 62 is mounted on the housing 1 and is drivenly connected to the second blocking member 61. In a plane perpendicular to the height direction Z of the cleaning device, the third driving member 62 can drive the second blocking member 61 to move closer to or away from the injection port 13.

[0063] In this embodiment, during the cleaning process of the cleaning device on the platform, the second switch assembly 6 can block the liquid injection port 13, thereby reducing the risk of external dust and other impurities entering the second cavity 112 and causing contamination of the cleaning fluid or blockage of the cleaning channel 14, and also reducing the risk of cleaning fluid splashing out of the housing 1 through the liquid injection port 13. The third drive member 62 drives the second sealing member 61 to move in a plane perpendicular to the height direction Z of the cleaning device, reducing the installation space required for the cleaning device in the height direction Z, thereby facilitating the installation and use of the cleaning device.

[0064] In one embodiment, the second blocking member 61 is a circular plate structure similar to the blocking part 511, and the third driving member 62 is directly connected to the second blocking member 61 to simplify the cost of the second switching assembly 6.

[0065] In another embodiment, such as Figure 5 As shown, the second switch assembly 6 also includes a rotating member 63, a first connecting rod 64, and a second connecting rod 65. One end of the rotating member 63 is hinged to the second sealing member 61, and the other end of the rotating member 63 is hinged to the first connecting rod 64. The end of the first connecting rod 64 away from the rotating member 63 is connected and fixed to the second connecting rod 65. The second connecting rod 65 is driven to be connected to the third driving member 62. The third driving member 62 can drive the second connecting rod 65 to rotate around its own axis. The second connecting rod 65 can drive the first connecting rod 64 to rotate synchronously. The first connecting rod 64 can pull the rotating member 63. The rotating member 63 can drive the second sealing member 61 to move closer to or away from the injection port 13.

[0066] In this embodiment, the second driving member 52 drives the first connecting rod 64 to swing through the rotation of the second connecting rod 65. The swing of the first connecting rod 64 drives the rotating member 63 to move, thereby realizing the movement of the second sealing member 61. This increases the flexibility of the installation position of the second driving member 52, that is, it can reasonably adjust the installation position of the first switch assembly 5 in order to reduce the overall size of the cleaning device.

[0067] The second switch assembly 6 can be disposed outside the housing 1 or installed inside the inner cavity 11. In this embodiment, as shown... Figure 3 As shown, the second switch assembly 6 is installed inside the cavity 11 to further reduce the overall size of the cleaning device.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
