[0001] The utility model belongs to the technical field of battery cell cleaning, and particularly relates to a battery cell cleaning device with electrostatic detection. Background Art

[0002] Existing battery modules are mostly assembled by stacking multiple battery cells. To extend the service life of the battery module and improve its performance and safety, it is generally necessary to clean the surface of the battery cells before stacking.

[0003] Dust, metal particles and other impurities may adhere to the surface of the battery cells. Some of these impurities will adhere to the battery cell electrodes, which may cause dangers such as short circuit, fire, or even explosion of the battery cells. In the prior art, the surface of the battery cells is usually cleaned by blowing air. At the same time, in order to avoid affecting the part of the battery cell with precision electronic components, a cover plate is usually provided to shield this part. In this way, a large amount of static electricity may accumulate at the cover plate and cannot dissipate, resulting in an electrostatic problem and making it difficult to ensure the safety of the battery cell cleaning process.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part rather than all of the embodiments of the present utility model.

[0040] Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0041] Example 1:

[0042] Please refer to Figure 1 and Figure 2 , a battery cell cleaning device with electrostatic detection, including a cleaning platform 100 for placing battery cells, a conductive cover plate 200 for covering a part of the battery cell, a driving component 300 for driving the conductive cover plate 200 to cover the battery cell, and a conductive component 400 for connecting the conductive cover plate 200 to an electrostatic detector (not shown in the figure).

[0043] The upper surface of the cleaning platform 100 is used to carry the battery cell, and the shape of its upper surface can be set to match the shape of the battery cell and the size is slightly larger than that of the battery cell. In this way, it can be adapted to carry battery cells of the same shape but different sizes.

[0044] Furthermore, a flexible board is usually carried on the battery cell for performance testing or monitoring of usage parameters of the battery cell. There may be protruding electronic components at the connection between the battery cell and the flexible board or at the position on the battery cell for connecting to the flexible board. Correspondingly, an avoidance position for avoidance can be formed on the upper surface of the cleaning platform 100 to ensure the flatness of the battery cell placed on the cleaning platform 100 and avoid damage to the protruding components.

[0045] As described above, at the connection between the battery cell and the flexible printed circuit board (FPC), or at the position on the battery cell for connecting with the FPC, there may be protruding electronic components, and some of the electronic components are relatively precise. During the blowing cleaning process using the blowing method, some of the electronic components may be damaged, or the impurities on the battery cell may escape and adhere to the electronic components when being blown away, thus affecting the quality of the battery cell. Therefore, in this embodiment, a conductive cover plate 200 is provided to cover some positions on the battery cell, and these positions are the positions where there are electronic components. Of course, they can also be the positions on the battery cell where cleaning operations are not required. The specific positions of these positions are not limited, and their distributions may vary slightly on different battery cells. The shape of the conductive cover plate 200 can be adjusted accordingly according to the distribution of the positions to be blocked on the battery cell.

[0046] The driving assembly 300 can adopt components with a driving function such as a cylinder, a module, etc. to drive the conductive cover plate 200, drive the conductive cover plate 200 to approach and cover some positions of the battery cell, or drive the conductive cover plate 200 away from the battery cell.

[0047] The conductive assembly 400 is used to connect the conductive cover plate 200 and the static electricity detector. The conductive cover plate 200 is used to cover some positions on the battery cell during the cleaning process of the battery cell. In this way, during the specific cleaning process, some impurities may escape and adhere to the conductive cover plate 200 under the blowing action, thus generating static electricity. The static electricity detector is used to detect the static electricity situation and ground, cut off the power supply and give an alarm according to the detection result.

[0048] In this embodiment, by providing the conductive cover plate 200 to cover some positions of the battery cell, the quality impact is avoided and the quality of the battery cell is improved; at the same time, by providing the conductive assembly 400 to connect the conductive cover plate 200 and the static electricity detector, the static electricity detection function can be achieved during the cleaning process of the battery cell, and the safety during the cleaning process of the battery cell is improved.

[0049] In some embodiments, the conductive assembly 400 includes a current collector 410 and a sliding contact wire 420. The sliding contact wire 420 connects the current collector 410 and the static electricity detector, and the current collector 410 connects the conductive cover plate 200, avoiding problems such as wire entanglement and wear that affect the operation, and ensuring the smoothness and safety of the cleaning process.

[0050] During different cleaning operation stages, the conductive cover plate 200 will be driven by the driving component 300 to move to different positions. For example, it moves towards or away from the cleaning platform 100. Therefore, if the traditional trailing wire grounding method is adopted, the trailing wire may be wound or worn as the conductive cover plate 200 moves, which not only affects the normal progress of the cleaning operation but also poses safety problems. In this embodiment, the current collector 410 is used in cooperation with the sliding contact wire 420. During the movement of the conductive cover plate 200, power can always be taken through the current collector 410, and the current collector 410 is connected to the static electricity detector through the sliding contact wire 420. Therefore, the static electricity detection function of the static electricity detector can be realized, and grounding and power-off alarms can be given in a timely manner according to the detection results.

[0051] Embodiment 2:

[0052] The difference between this embodiment and Embodiment 1 is that in this embodiment, further structural optimization is carried out on the core cleaning device of the present utility model. Please refer to Figure 3 and Figure 4 .

[0053] A reference edge 110 for core positioning is provided on one side of the cleaning platform 100, and a plurality of adsorption holes 120 for adsorbing the core are also formed on the cleaning platform 100. The core is positioned and located through the reference edge 110 and the adsorption holes 120 to ensure the stability of the core position during the cleaning process.

[0054] For example, a reference edge 110 is provided on one side edge of the cleaning platform 100. When the core is placed on the cleaning platform 100, one side edge of the core is abutted against the reference edge 110 to limit the placement position of the core. In addition, after the core is placed in place, a plurality of adsorption holes 120 generate a vacuum adsorption effect to suck the lower surface of the core to prevent the core from moving due to the action of gas during the blowing cleaning process.

[0055] It should be noted that in this embodiment, the number and distribution positions of the adsorption holes 120 are not specifically limited. The plurality of adsorption holes 120 can be unevenly or evenly distributed. For example, in one example, the number of adsorption holes 120 is twelve, and the twelve adsorption holes 120 are spaced around the edge of the core to have a better adsorption effect on the core.

[0056] In some embodiments, the conductive cover plate 200 is made of copper material, which has good electrical conductivity and can improve the accuracy of static electricity detection.

[0057] It is known that copper is one of the metals with the strongest electrical conductivity and its material is relatively easy to obtain. Using the copper material for the conductive cover plate 200 can better cooperate with the static electricity detector for static electricity detection to ensure the safety of the cleaning operation.

[0058] Further, the driving assembly 300 includes an inclined driving cylinder which drives the conductive cover plate 200 to move relative to the X-axis and Y-axis of the battery cell 800 simultaneously. Refer to Figure 4 As shown, this relatively inclined driving method can reduce the movement of the conductive cover plate relative to the surface of the battery cell, and reduce the generation of static electricity and interference with the battery cell.

[0059] Embodiment 3:

[0060] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the battery cell cleaning device of the present utility model. Please refer to Figure 5 and Figure 6 .

[0061] The battery cell cleaning device further includes a pushing assembly 500 which is used to push the flexible board on the battery cell to be limited below the conductive cover plate 200, ensuring the shielding effect on the flexible board on the battery cell and preventing damage to the flexible board.

[0062] As known from the content of Embodiment 1, a flexible board is usually carried on the battery cell for performance testing or monitoring of usage parameters of the battery cell, and some electronic components are usually carried on the flexible board. To avoid affecting the electronic components on the flexible board during the blowing cleaning process, the pushing assembly 500 is set to push the flexible board towards the conductive cover plate 200, so that the flexible board is limited below the conductive cover plate 200, and the conductive cover plate 200 is used to shield the flexible board.

[0063] Specifically, the pushing assembly 500 includes a pushing cylinder 510 and a pushing block 520. The pushing block 520 is connected to the driving end of the pushing cylinder 510, and the pushing block 520 is pushed to move by the pushing cylinder 510 to realize the pushing and limiting effect on the flexible board.

[0064] Further, to prevent the pushing block 520 from being over-pushed by the pushing cylinder 510 and causing hard force contact with the flexible board to damage the flexible board, a buffer layer is provided on the surface of the pushing block 520 for contacting the flexible board on the battery cell. The buffer layer can be made of elastic materials such as foam or plastic parts.

[0065] In some embodiments, a sliding guiding assembly 600 is further provided between the pushing block 520 and the driving end of the pushing cylinder 510. The sliding guiding assembly 600 can enable the pushing block 520 to move along a predetermined path under the driving action of the pushing cylinder 510.

[0066] Specifically, the sliding guide assembly 600 includes a sliding mount 610 and a slide rail 620 that are slidably connected. The sliding mount 610 is connected to the driving end of the pushing cylinder 510. The pushing block 520 is arranged on the sliding mount 610. The extending direction of the slide rail 620 is the same as the pushing direction of the pushing cylinder 510. Under the pushing action of the pushing cylinder 510, the sliding mount 610 moves on the slide rail 620, thereby driving the pushing block 520 to move, achieving a stable guiding effect on the sliding of the pushing block 520 and ensuring the accuracy of the pushing operation.

[0067] Furthermore, the battery cell cleaning device further includes a buffer assembly 700. The buffer assembly 700 includes a buffer limiting plate 710, a connecting rod 720, and a spring 730. The connecting rod 720 sequentially passes through the buffer limiting plate 710, the spring 730, and the sliding mount 610.

[0068] When the pushing block 520 is over-pushed by the pushing cylinder 510 and the pushing soft board abuts in place, here, it can be understood that there is a stop block for restricting the moving distance of the soft board in the pushing direction of the pushing block 520. When the pushing block 520 is subjected to the abutting action of the stop block, it drives the sliding mount 610 to move in the reverse direction, causing the sliding mount 610 to slide relative to the connecting rod 720 and compress the spring 730, so as to prevent the soft board from being damaged by hard force contact.

[0069] A battery cell cleaning device with electrostatic detection provided by the present utility model covers a part of the battery cell with a conductive cover plate to avoid quality impact and improve the quality of the battery cell; at the same time, by providing a conductive assembly for connecting the conductive cover plate and the electrostatic detector, it can play an electrostatic detection role during the cleaning process of the battery cell, improving the safety during the cleaning process of the battery cell. Moreover, adopting the conductive method of the current collector cooperating with the sliding contact wire can avoid phenomena such as entanglement or wear that may occur when the trailing wire moves with the conductive cover plate, ensuring the normal progress and safety of the cleaning operation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0071] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0072] In addition, the terms "horizontal", "vertical", "overhanging", etc. do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0073] In the present utility model, unless otherwise clearly specified and defined, the first feature being above or below the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween.

The first feature being below, under and beneath the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.
