[0003] The relevant technology involves manually wiping and cleaning the testing device. This cleaning method requires the equipment to be shut down, which reduces the overall testing efficiency of the equipment. Therefore, how to reduce the negative impact of cleaning the testing device on the testing efficiency of the equipment is a research direction in battery technology. Utility Model Content

[0004] This application provides a battery testing device and a battery production system that can reduce the negative impact of cleaning on the testing efficiency of the device.

[0005] In a first aspect, embodiments of this application provide a battery testing device, including a frame, a cleaning component, a moving device, and a testing device.

[0006] By adopting the above technical solution, the battery testing equipment is configured to include a cleaning component. When cleaning of the testing device is required, the testing device is directly moved to the fixed cleaning component for cleaning, eliminating the need to stop the machine for manual cleaning of the testing device. This can improve cleaning efficiency and free up manpower.

[0007] In some embodiments of this application, the cleaning component includes a mounting base and a cleaning part mounted on the mounting base, the mounting base being mounted on the frame, and the cleaning part being configured to rub against the detection device to clean the detection device.

[0008] The above technical solution designs the cleaning component as including a mounting base and a cleaning part mounted on the mounting base. The mounting base facilitates the connection between the cleaning component and the frame, and the cleaning part cleans the detection device by friction with the detection device. The structure is simple and easy to implement.

[0009] In some embodiments of this application, the cleaning unit includes bristles.

[0010] By adopting the above technical solution, the cleaning part is designed to include bristles. The bristles can achieve a good cleaning effect during the process of friction with the detection device, and can reduce the damage to the surface of the detection device during the cleaning process.

[0011] In some embodiments of this application, the moving device is used to drive the detection device to reciprocate along a first direction and / or a second direction, so that the cleaning part rubs against the detection device, wherein the first direction, the second direction, and the arrangement direction of the moving device to the detection device intersect each other in pairs.

[0012] By adopting the above technical solution, the cleaning part is driven to reciprocate along the first direction and / or the second direction by the moving device to achieve mutual friction between the cleaning part and the detection device, thereby improving the cleaning effect.

[0013] In some embodiments of this application, the battery testing device includes a second mounting member connected to the mobile device. The number of testing devices is multiple, and the multiple testing devices are spaced apart on the second mounting member along a first direction, which intersects the arrangement direction of the mobile device to the testing devices.

[0014] By adopting the above technical solution, the battery testing equipment is designed to include a second mounting component, and multiple testing devices are installed on the same second mounting component, which facilitates the installation and synchronous movement of multiple testing devices for cleaning and testing, thereby improving the efficiency of testing and cleaning.

[0015] In some embodiments of this application, the battery testing device includes a first mounting member mounted on the frame, and a plurality of cleaning members are installed at intervals along a first direction on the first mounting member.

[0017] In some embodiments of this application, the center-to-center distance between two adjacent detection devices along the first direction is equal to the center-to-center distance between two adjacent cleaning components along the first direction.

[0018] By adopting the above technical solution, along the first direction, the center distance between the two detection devices is designed to be equal to the center distance between the two cleaning components, so that when multiple detection devices move to the cleaning position, they can cooperate with multiple cleaning components to achieve synchronous cleaning of multiple detection devices.

The second direction intersects the first direction and the arrangement direction of the moving device to the detection device.

[0020] By adopting the above technical solution, the first mounting component is designed to include a first mounting part and a first stop part. The first mounting part facilitates the connection between the first mounting component and the first frame, while the stop part reduces the possibility of dust and other impurities generated during the cleaning process of the detection device detaching from the first mounting component.

[0021] In some embodiments of this application, the first mounting component is detachably connected to the frame.

[0022] By adopting the above technical solution, the first mounting component and the frame are designed to be detachably connected, which facilitates the disassembly and replacement of the first mounting component and the cleaning component.

[0023] In some embodiments of this application, the battery testing device includes a first mounting member mounted on the frame, a cleaning member of one size, the cleaning member being integrally mounted on the first mounting member along a first direction, the first direction intersecting the arrangement direction from the moving device to the testing device, and multiple testing devices, the distance between two testing devices located at both ends of the multiple testing devices being less than or equal to the length of the cleaning member along the first direction.

[0024] By adopting the above technical solution, the number of cleaning components is designed to be one, and the cleaning component is arranged along the first direction. Along the first direction, the length of the whole formed by the multiple detection devices is equal to the length of the cleaning component, which can satisfy the requirement that multiple detection devices perform cleaning actions on one cleaning component at the same time.

[0025] In some embodiments of this application, the frame is provided with a cleaning platform, and the cleaning component is connected to the cleaning platform.

[0026] By adopting the above technical solution, a cleaning platform is provided on the frame, which facilitates the installation of cleaning components.

[0027] In some embodiments of this application, the frame has opposite first and second ends, the cleaning platform is located at the first end, and the moving device is used to drive the detection device to move between the first and second ends.

[0028] By adopting the above technical solution, the cleaning platform is designed to be located at the first end of the rack, so that the cleaning components can be as far away as possible from the detection position in the middle area of ​​the rack, while the cleaning components at the first end can provide a larger cleaning space.

[0029] In some embodiments of this application, the battery testing device further includes a testing platform for placing a battery device, the testing platform being located between the first end and the second end.

[0030] Using the above technical solution, the testing platform is designed to be located between the first end and the second end. After the moving device drives the testing device to perform testing, it continues to move the testing device towards the first end to clean the part.

[0031] In some embodiments of this application, the frame is provided with a guide rail, the moving device is connected to the guide rail and configured to move along the extension direction of the guide rail, the extension direction of the guide rail intersecting the arrangement direction of the moving device to the detection device.

[0032] By adopting the above technical solution, the mobile device is installed on the guide rail and moves on the guide rail, which can improve the stability of the mobile device and the detection device during the movement process.

[0033] In some embodiments of this application, the moving device is configured to drive the detection device to move along the alignment direction of the moving device to the detection device.

[0034] By adopting the above technical solution, the mobile device is designed to move along the extension direction of the guide rail and along the arrangement direction from the mobile device to the detection device, so that the mobile device can drive the detection device to move in two degrees of freedom, which facilitates the detection device to perform detection and cleaning.

[0035] In some embodiments of this application, the moving device is configured to move the detection device along directions intersecting the extension direction of the guide rail and the arrangement direction of the moving device to the detection device.

[0036] By adopting the above technical solution, the mobile device is designed to move along the extension direction intersecting the guide rail and the arrangement direction from the mobile device to the detection device, so that the mobile device can drive the detection device to move along three degrees of freedom, further facilitating the detection device to perform detection and cleaning actions.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "including," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0059] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0060] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0061] In this application, the term "and / or" 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, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0062] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0063] In this application, "multiple" means two or more (including two).

[0064] Currently, battery devices are being used more and more widely. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As the application areas of battery devices continue to expand, the market demand is also constantly increasing.

[0065] During the production of battery devices, battery testing is required. Open circuit voltage testing (OCV) is an important part of battery performance testing, mainly used to evaluate the battery's charge and discharge status, capacity, and aging degree.

[0066] Open circuit voltage testing typically involves connecting the battery device and the testing circuit using a probe or other testing device. After a period of testing, dirt will accumulate on the probe's surface, affecting the accuracy of the test and requiring regular cleaning.

[0067] The relevant technology usually involves manually wiping the voltage probe surface with a lint-free cloth soaked in alcohol to remove dirt and ensure voltage testing accuracy. However, this method is difficult to remove hard impurities; moreover, manual cleaning is inefficient and poses a risk of probe contamination; in addition, the machine needs to be stopped for a period of time after cleaning, such as 15 minutes, which reduces the overall testing efficiency of the testing equipment and the production efficiency of the entire production line.

[0068] Therefore, improving the cleaning efficiency and effectiveness of probes, and reducing the possibility of reduced detection efficiency of testing equipment due to probe cleaning, is an important issue in battery production and processing.

[0069] In view of this, this application provides a technical solution that solves the above-mentioned technical problems by adding a cleaning component to the battery testing equipment and configuring the mobile device to not only drive the testing device to perform the testing action, but also drive the testing device to perform cleaning.

[0070] The following is in conjunction with the appendix Figures 1-6 The battery testing device 100 provided in the embodiments of this application will be described.

[0071] Combined with appendix Figure 1-3As shown, this application embodiment provides a battery testing device 100, including a frame 10, a cleaning component 20, a moving device 30, and a testing device 40. The cleaning component 20 is mounted on the frame 10, and the moving device 30 is mounted on the frame 10. The testing device 40 is connected to the moving device 30. The moving device 30 is configured to move the testing device 40 to the battery device 200 to perform a testing action, and to move the testing device 40 to the cleaning component 20. The cleaning component 20 is used to clean the testing device 40.

[0072] The frame 10 serves as the mounting base for the cleaning component 20 and the moving device 30. The structure of the frame 10 is not limited, as long as it can accommodate the installation of the cleaning component 20, the moving device 30, and the cleaning platform 70 and the detection platform 80 described below.

[0073] In some embodiments, the frame 10 includes a support member 11 and a mounting frame 12. There are multiple support members 11, and the mounting frame 12 can be directly mounted on the multiple support members 11. The moving device 30 can be directly mounted on the mounting frame 12.

[0074] The mobile device 30 can move on the frame 10 and / or has a movable free end. The mobile device 30 moves the detection device 40 by its own movement, thereby moving the detection device 40 to the detection position to detect the battery device 200, and can also move the detection device 40 to the cleaning position to cooperate with the cleaning component 20 for cleaning.

[0075] The structure of the mobile device 30 can be a robotic arm capable of moving in multiple degrees of freedom (e.g., the first direction X, the second direction Y, and the third direction Z in the figure), or it can include the linear motion structure described below. The specific structure of the mobile device 30 is given below.

[0076] The detection device 40 is connected to the moving device 30. The connection method can be any mechanical connection method that can ensure the relative stability of the two, such as bolt connection, welding, bonding, snap-fit, etc. This embodiment will not list them one by one.

[0077] The detection device 40 includes a probe, the main function of which is to connect the positive and negative terminals of the battery device 200 to a detection circuit (not shown in the figure) to measure the open-circuit voltage of the battery device 200.

[0078] The probe can be made of conductive materials, offering good conductivity and durability. During use, the probe comes into contact with battery electrolyte and other chemicals, therefore requiring regular cleaning to remove contaminants that may affect measurement accuracy. Cleaning the probe improves test repeatability and reliability, and extends its lifespan.

[0079] The cleaning component 20 is mounted on the rack 10. Specifically, the cleaning component 20 can be directly mounted on the rack 10, or the cleaning component 20 can be mounted on the rack 10 through an intermediate structure (such as the first mounting component 50 described below).

[0080] The cleaning component 20 refers to a structure that can remove impurities from the surface of the detection device 40 when the detection device 40 enters its cleaning range and when the detection device 40 is driven to perform a cleaning action by the moving device 30.

[0081] Along the first direction X and the second direction Y in the figure, the size of the cleaning component 20 is larger than the size of the detection device 40. The cleaning component 20 may not move at all, or it may move to cooperate with the cleaning action of the cleaning component 20 (this embodiment is not shown in the figure) to improve the cleaning effect.

[0082] In some embodiments, the cleaning step may be performed during the testing process of the testing equipment, before the testing of a batch of battery devices 200, or after the testing of a batch of battery devices 200.

[0083] When a person observes that the surface of the testing device 40 needs to be cleaned, or when the equipment's control system determines (for example, after running for a period of time) that the testing device 40 needs to be cleaned, or after each batch of battery devices 200 is tested, the moving device 30 directly moves the testing device 40 to the fixed cleaning part 20 to perform the cleaning action. There is no need to completely stop the machine to manually clean the testing device 40, which can improve cleaning efficiency and free up manpower.

[0084] Combined with appendix Figure 4 and 5 As shown, in some examples, optionally, the cleaning component 20 includes a mounting base 21 and a cleaning part 22 mounted on the mounting base 21, the mounting base 21 being mounted on the frame 10, and the cleaning part 22 being configured to rub against the detection device 40 to clean the detection device 40.

[0085] Mounting base 21 is mounted on rack 10, meaning that mounting base 21 can be directly mounted on rack 10 or indirectly mounted on rack 10 through an intermediate structure (such as the first mounting member 50 described below).

[0086] The reason for designing the mounting base 21 is that the cleaning part 22 needs to rub against the detection device 40 to clean the detection device 40. Therefore, the cleaning part 20 is at least partially non-rigid and it is not convenient to make mechanical connection with the frame 10. Therefore, in this embodiment, the cleaning part 20 is designed to include the mounting base 21 and the cleaning part 22 mounted on the mounting base 21, and the mounting base 21 is used to facilitate the docking of the cleaning part 20 with the frame 10.

[0087] The cleaning part 22 is a device that can remove the detection device 40 after rubbing against it. The material of the cleaning part 22 can be a flexible material such as fur or cloth, or a material that can undergo elastic deformation such as rubber, silicone or plastic.

[0088] When the detection device 40 reaches the cleaning position, it needs to be at least partially embedded in the cleaning part 22. Then, the detection device 40 is moved by the moving device 30. The detection device 40 is cleaned by the friction between the cleaning part 22 and the detection device 40. The whole cleaning process is simple to operate. The original moving device 30 is used to clean the detection device 40 directly. There is no need to configure a drive device for the cleaning part 20, which simplifies the structure and reduces the equipment production cost.

[0089] In some examples, the cleaning section 22 may optionally include bristles.

[0090] The cleaning unit 22 is designed to include bristles, which can achieve a good cleaning effect during the process of friction with the detection device 40 and reduce damage to the surface of the detection device 40 during the cleaning process.

[0091] The bristles refer to a structure consisting of multiple bristles connected to the mounting base 21 by a mechanical connection. In some embodiments, the bristles refer to slender structures with a diameter between 0.1mm and 10mm, and the number of bristles is multiple, such as 10 to 1000.

[0092] The mounting base 21 and the bristles together form a brush structure. The mounting base 21 is equivalent to the brush plate of the brush structure. In some embodiments, the mounting base 21 can be used as a brush plate, or a brush plate can be configured on the mounting base 21 to support the bristles.

[0093] The bristles can be made of materials such as fur, cloth, rubber, silicone, and plastic, as well as nylon or metal, etc. This embodiment will not list them all.

[0094] In some embodiments, the bristles may be stiff bristles, such as those made of plastic or metal, which can effectively remove hard impurities and improve cleaning effectiveness and efficiency.

[0095] In some examples, the moving device 30 is optionally used to drive the detection device 40 to reciprocate along the first direction X and / or the second direction Y, so that the cleaning part 22 and the detection device 40 are coated with each other, and the first direction X, the second direction Y and the arrangement direction of the moving device 30 to the detection device 40 intersect each other in pairs.

[0096] The moving device 30 can drive the detection device 40 to reciprocate. Through the reciprocating friction between the cleaning part 22 and the detection device 40, impurities that are difficult to remove can be removed more effectively, thereby improving cleaning efficiency.

[0097] Furthermore, the moving device 30 can drive the detection device 40 to move along the first direction X, or it can drive the detection device 40 to move along the second direction Y, so that the cleaning part 22 can reciprocate in multiple directions, thereby enabling the cleaning part 22 to make frictional contact with more positions of the detection device 40, thereby further improving the cleaning efficiency.

[0098] In some examples, the battery testing device 100 may optionally include a second mounting member 60 connected to the mobile device 30, and a plurality of testing devices 40 are mounted at intervals along a first direction X on the second mounting member 60, the first direction X intersecting the arrangement direction of the mobile device 30 to the testing devices 40.

[0099] The number of detection devices 40 is designed to be multiple, which means two or more (e.g., four in the figure). The moving device 30 can move multiple detection devices 40 at the same time, thereby detecting multiple battery devices 200 at the same time, and can move multiple detection devices 40 to multiple cleaning parts 20 for cleaning.

[0100] The second mounting component 60 can be a plate-shaped component or a block-shaped component, etc. In some embodiments, the second mounting component 60 is provided with a mounting groove 61, and the extension direction of the mounting groove 61 is set along the first direction X in the figure. Multiple detection devices 40 are directly installed in the mounting groove 61.

[0101] In some embodiments, optionally, each detection device 40 can be positioned on the mounting groove 61 along the first direction X. For example, the detection device 40 can be slidably connected to the mounting groove 61, thereby facilitating the adjustment of the distance between two adjacent detection devices 40.

[0102] Alternatively, the detection device 40 can be designed to be connected to a drive component (such as a wheel) that can move along the first direction X on the mounting slot 61, so that the drive component can drive the detection device 40 to move along the first direction X. This not only makes it easy to adjust the spacing between adjacent detection devices 40, but also allows the detection device 40 to move back and forth along the first direction X during cleaning to improve the cleaning effect.

[0103] Of course, in addition to the above-mentioned moving device 30 driving the detection device 40 to reciprocate to achieve friction between the detection device 40 and the cleaning part 22, the cleaning part 22 itself can also reciprocate (this embodiment is not shown in the figure).

[0104] Combined with appendix Figure 2 and 3 As shown, in some examples, optionally, the battery testing device 100 includes a first mounting member 50, which is mounted on the frame 10, and a plurality of cleaning members 20 are mounted at intervals along a first direction X on the first mounting member 50.

[0105] The first mounting component 50 can be in the shape of a plate, a block, or a frame structure with supporting legs, as long as it can accommodate the installation of multiple cleaning components 20.

[0106] In actual application of the equipment, the arrangement direction of the moving device 30 to the detection device 40 can be vertical (the third direction Z in the figure), and the first direction X intersects the arrangement direction of the moving device 30 to the detection device 40. The first direction X and the third direction Z can form an angle greater than 0° and less than or equal to 90°.

[0107] In some embodiments, the first direction X is perpendicular to the third direction Z, and the first direction X can be a horizontal direction.

[0108] The number of cleaning components 20 is multiple, which means two or more, such as the four in the figure. Of course, the specific number can be determined according to the cleaning needs, which will not be described in detail in this embodiment.

[0109] In this embodiment, multiple cleaning components 20 are installed on the first mounting component 50 to achieve integrated installation of multiple cleaning components 20. The cleaning components 20 can be fixedly connected to the first mounting component 50, or they can be detachably installed on the first mounting component 50 by means of threaded connection, plug-in connection or other means.

[0110] In this embodiment, the number of cleaning components 20 is designed to be multiple, which facilitates the cooperation between the detection device 40 and the cleaning components 20. The reason is that when there is only one detection device 40, one detection device 40 can first cooperate with one of the cleaning components 20 for friction cleaning, and then move to rub with another cleaning component 20, which can effectively improve the cleaning effect.

[0111] Of course, when there are multiple detection devices 40, each detection device 40 can choose to cooperate with a cleaning element 20 that is closest to it in the second direction Y, or it can cooperate with other cleaning elements 20 after cooperating with the cleaning element 20 that is closest to it in the second direction Y, so as to improve the effect of impurity removal.

[0112] In some examples, optionally, the center-to-center distance between two adjacent detection devices 40 along the first direction X is equal to the center-to-center distance between two adjacent cleaning components 20 along the first direction X.

[0113] The center distance refers to the distance between the middle positions of two adjacent detection devices 40 or cleaning components 20 along the first direction X. In the figure, the center distance between two adjacent detection devices 40 along the first direction X is a, and the center distance between two adjacent cleaning components 20 along the first direction X is b, where a = b.

[0114] Along the first direction X, the center distance between the two detection devices 40 is designed to be equal to the center distance between the two cleaning components 20, so that when the multiple detection devices 40 move to the cleaning position (the detection devices 40 at least partially extend into the cleaning components 20), they can cooperate with the multiple cleaning components 20 one by one to achieve synchronous cleaning of the multiple detection devices 40.

[0115] Combined again with the appendix Figure 2 As shown, in some examples, optionally, the first mounting member 50 includes a first mounting portion 51 and a first stop portion 52. The first mounting portion 51 is connected to the frame 10, and the first stop portion 52 is connected to at least one side of the first mounting portion 51 along the second direction Y and protrudes from the first mounting portion 51 along the arrangement direction of the moving device 30 to the detection device 40. The second direction Y intersects the first direction X and the arrangement direction of the moving device 30 to the detection device 40.

[0116] The first mounting component 50 can be made of metal, plastic, or other materials, which will not be listed in this embodiment.

[0117] The first mounting part 51 can be mechanically connected to the frame 10 (specifically, it can be connected to the cleaning platform 70 described below). The specific connection method is given below. The first mounting part 51 facilitates the connection between the first mounting member 50 and the first frame 10.

[0118] In some embodiments, the first direction X, the second direction Y, and the third direction Z intersect each other. Specifically, the first direction X, the second direction Y, and the third direction Z may be perpendicular to each other, in which case the second direction Y is another horizontal direction perpendicular to the first direction X.

[0119] In this embodiment, the first stop portion 52 can be integrally connected to the first mounting portion 51 or integrally formed during processing, or the connection between the two can be achieved through other mechanical connection methods.

[0120] The first stop portion 52 is connected to at least one side of the first mounting portion 51 along the second direction Y, meaning that the number of first stop portions 52 can be one or two.

[0121] When there is one first stop part 52, one first stop part 52 is connected to one side of the first mounting part 51 along the second direction Y. When there are two first stop parts 52 as shown in the figure, the two first stop parts 52 are connected one-to-one to the two sides of the first mounting part 51 along the second direction Y.

[0122] In some embodiments, the size of the first stop portion 52 along the first direction X can be designed to be greater than or equal to the size of the first mounting portion 51 along the first direction X.

[0123] The first stop 52 can reduce the possibility that dust and other impurities generated during the cleaning process of the detection device 40 will detach from the first mounting member 50 along the second direction Y.

[0124] In addition, a second stop portion (not shown in the figure) can be provided on at least one side of the first mounting portion 51 along the first direction X to further reduce the possibility of dust and other impurities detaching from the first mounting member 50.

[0125] In some examples, the first mounting element 50 is optionally detachably connected to the rack 10.

[0126] Detachable connection means that the first mounting part 50 can be removed after being connected to the frame 10 without damaging the structure of the first mounting part 50 and the frame 10.

[0127] There are various ways to detach the connection, such as snap-fit ​​connection, threaded connection, plug-in connection, etc., which will not be listed one by one in this embodiment.

[0128] The first mounting component 50 is designed to be detachably connected to the frame 10, which facilitates the disassembly and replacement of the first mounting component 50 and the cleaning component 20.

[0129] Combined with appendix Figure 6 As shown, in some examples, optionally, the battery testing device 100 includes a first mounting member 50, which is mounted on the frame 10. The number of cleaning members 20 is one, and the cleaning member 20 is integrally mounted on the first mounting member 50 along a first direction X. The first direction X intersects the arrangement direction of the moving device 30 to the testing device 40. The number of testing devices 40 is multiple, and the distance between two testing devices 40 at both ends is less than or equal to the length of the cleaning member 20 along the first direction X.

[0130] The cleaning component 20 is integrally mounted on the first mounting component 50 along the first direction X. This means that the length of the cleaning component 20 along the first direction X can be equal to or slightly less than the length of the first mounting component 50. In some embodiments, the difference between the length of the cleaning component 20 along the first direction X and the length of the first mounting component 50 along the first direction X can be 1mm-100mm.

[0131] There are multiple detection devices 40, and multiple detection devices 40 can be installed on the second mounting component 60.

[0132] The distance between two detection devices 40 located at both ends is less than or equal to the length of the cleaning component 20 along the first direction X. This can be understood as the length of the overall outline of the multiple detection devices 40 along the first direction X being less than or equal to the length of the cleaning component 20 along the first direction X.

[0133] During cleaning, multiple detection devices 40 can be inserted into a cleaning component 20, which allows multiple detection devices 40 to perform cleaning actions on a single cleaning component 20 simultaneously.

[0134] Combined again with the appendix Figure 1-3 As shown, in some examples, the rack 10 is optionally provided with a cleaning platform 70, to which the cleaning component 20 is connected.

[0135] The cleaning platform 70 should be interpreted broadly, referring to a structure that can provide a flat packaging surface. The cleaning platform 70 can be a plate-like or block-like structure.

[0136] The cleaning platform 70 can be mechanically fixed to the support member 11 or the mounting frame 12 of the frame 10. In some embodiments, the cleaning platform 70 can be connected to the support member 11 by welding, bolting or other means.

[0137] The cleaning component 20 is mounted on the cleaning platform 70. In some embodiments, the first mounting component 50 may be detachably mounted on the cleaning platform 70 by bolt connection.

[0138] Combined again with the appendix Figure 1 As shown, in some examples, optionally, the rack 10 has opposite first end 13 and second end 14, the cleaning platform 70 is located at the first end 13, and the moving device 30 is used to drive the detection device 40 between the first end 13 and the second end 14.

[0139] In some embodiments, the mounting frame 12 of the rack 10 may have a guide structure such as a guide rail 15, the extension direction of which is set along the direction from the first end 13 to the second end 14 (the second direction Y in the figure).

[0140] The mobile device 30 can be slidably connected to the slide rail and slide along the second direction Y on the slide rail through an external driving structure or its own walking structure (not shown in the figure).

[0141] Of course, the moving device 30 can also be designed to include a linear reciprocating motion mechanism that moves linearly along the second direction Y to replace the walking structure. The linear reciprocating motion mechanism can be a cylinder, an electric cylinder, or a hydraulic cylinder, etc. By installing the fixed part (cylinder body) of the linear reciprocating motion mechanism on the mounting frame 12 of the frame 10, the linear reciprocating motion part of the linear reciprocating motion mechanism is connected to the detection device 40 or the second mounting member 60 mentioned above, thereby driving the detection device 40 to move along the second direction Y.

[0142] The cleaning platform 70 is designed to be located at the first end 13 of the frame 10, so that the cleaning component 20 can be as far away from the detection position in the middle area of ​​the frame 10 as possible. When the cleaning component 20 reaches the first end 13, the cleaning component 20 along the second direction Y can extend outward from the frame 10, thus having a larger cleaning space, which makes it convenient for the moving device 30 to drive the cleaning component 20 to perform cleaning actions.

[0143] In some examples, the battery testing device 100 may optionally include a testing platform 80 for placing the battery device 200, the testing platform 80 being located between the first end 13 and the second end 14.

[0144] The testing platform 80 is mainly used to place the battery device 200. In some embodiments, the testing platform 80 can be a plate or a block. Furthermore, several limiting structures (not shown in the figure) for limiting and fixing the battery cells can be provided on the testing platform 80 to maintain the stability of the battery device 200 during the testing process.

[0145] The testing platform 80 can be connected to the rack 10, or it can be located inside the inner contour of the rack 10 without being connected to the rack 10.

[0146] The detection platform 80 is designed to be located between the first end 13 and the second end 14. After the moving device 30 drives the detection device 40 to perform detection, it continues to drive the detection device 40 to move towards the first end 13 to the cleaning component 20 for cleaning.

[0147] In some examples, the frame 10 may optionally be provided with a guide rail 15, to which the moving device 30 is connected and configured to move along the extension direction of the guide rail 15, the extension direction of the guide rail 15 intersecting the arrangement direction of the moving device 30 to the detection device 40.

[0148] In some embodiments, the guide rail 15 may be provided with a guide groove (not shown in the figure), and the moving device 30 includes a slider or pulley located in the guide groove to realize the moving device 30 moving along the guide rail 15.

[0149] The length direction of the guide rail 15 is set along the second direction Y in the figure. The moving device 30 is provided with a walking structure, which is connected to the slide rail. The walking structure may include a rolling element or a sliding element, and moves along the second direction Y on the guide rail 15, which can improve the stability of the moving device 30 and the detection device 40 during the movement process.

[0150] In some examples, the moving device 30 is optionally configured to move the detection device 40 along the arrangement direction of the moving device 30 to the detection device 40.

[0151] The arrangement direction of the mobile device 30 to the detection device 40 is the third direction Z in the figure. In some embodiments, the third direction Z is the vertical direction.

[0152] Based on the aforementioned walking structure of the mobile device 30, the mobile device 30 can be designed to have a first linear reciprocating motion structure (not shown in the figure). The first linear reciprocating motion structure is connected to the aforementioned walking structure. The first linear reciprocating motion structure can be a cylinder, an electric cylinder, or a hydraulic cylinder, or it can be a gear rack, crank slider, or other structure powered by an electric motor.

[0153] The first linear reciprocating motion structure enables the moving device 30 to not only drive the detection device 40 to move along the second direction Y, but also to drive the detection device 40 to move along the third direction Z, so that the moving device 30 can drive the detection device 40 to move along two degrees of freedom.

[0154] When cleaning the detection device 40, the moving device 30 first moves the detection device 40 along the second direction Y to above the cleaning component 20, then moves the detection device 40 down to extend into the cleaning component 20, and then moves the detection device 40 again along the second direction Y and / or the third direction Z, so that the cleaning component 20 and the detection device 40 generate friction to clean the detection device 40, which can facilitate the detection and cleaning of the detection device 40.

[0155] In some examples, the moving device 30 is optionally configured to move the detection device 40 in directions that intersect the extension direction of the guide rail 15 and the arrangement direction of the moving device 30 to the detection device 40.

[0156] In some embodiments, the direction intersecting the extension direction of the guide rail 15 and the arrangement direction of the moving device 30 to the detection device 40 can be the first direction X in the figure.

[0157] The moving device 30 may also include a second linear reciprocating motion structure (not shown in the figure), which is connected to the first linear reciprocating motion structure, and the second mounting member 60 is connected to the second linear reciprocating motion structure.

[0158] The second linear reciprocating motion structure can also be the aforementioned cylinder, hydraulic cylinder, or electric cylinder, etc.

[0159] The mobile device 30 is designed to also be able to move along the first direction X, so that the mobile device 30 can drive the detection device 40 to move along three degrees of freedom.

[0160] During cleaning, the moving device 30 can drive the detection device 40 to move along one or more of the first direction X, the second direction Y, and the third direction Z, thereby improving the cleaning effect.
