Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery cleaning device, a battery cleaning method, and a battery production system. Background Technology

[0002] During the production of battery devices, an electrolyte injection device is required. Specifically, the electrolyte injection device injects electrolyte into the battery cell through the electrolyte injection port of the battery cell.

[0003] Electrolyte residue is prone to accumulate at the injection port after electrolyte filling. If not cleaned promptly, it not only affects subsequent processes but also negatively impacts the quality of the battery device. Therefore, how to clean residual electrolyte at the injection port is a research direction in battery technology. Summary of the Invention

[0004] This application provides a battery cleaning device, a battery cleaning method, and a battery production system, which can clean residual electrolyte at the filling port. In a first aspect, embodiments of this application provide a battery cleaning device, including an unwinding device, a cutting device, an adsorption feeding device, a receiving device, and a wiping device. The unwinding device includes a material tray and a dragging mechanism. The material tray is used to carry a rolled wiping component, and the dragging mechanism is used to pull the wiping component out of the material tray. The cutting device is used to cut the wiping component pulled out by the dragging mechanism. The adsorption feeding device is located above the unwinding device and is used to adsorb the wiping component pulled out by the dragging mechanism and transport the cut wiping component. The receiving device is arranged along a first direction with the dragging mechanism and is used to receive the wiping component transported by the adsorption feeding device. The first direction is the pulling direction of the wiping component. The wiping device is located above the unwinding device and the receiving device and is used to pick up the wiping component in the receiving device and drive the wiping component to clean the battery filling port.

[0005] The above technical solution involves unwinding the wiping component using an unwinding device, adsorbing and fixing the pulled-out wiping component using an adsorption feeding device, then placing the wiping component, which has been cut by the cutting device, into a receiving device for transfer. Finally, the wiping device picks up the wiping component to clean the battery filling port. This not only enables rapid cleaning of the filling port, reduces electrolyte residue, and improves product quality, but also ensures that the wiping component is always fixed before cleaning, maintaining a stable posture and higher accuracy in conveying and placing, which is beneficial for subsequent pickup by the wiping device.

[0006] In some embodiments of this application, the receiving device includes a plurality of receiving boxes arranged at intervals along the first direction, and the adsorption feeding device is used to place the plurality of cut wiping pieces one by one into the plurality of receiving boxes.

[0007] By adopting the above technical solution and setting up multiple receiving boxes, the adsorption feeding device can pre-place multiple wiping parts at the same time. When the subsequent adsorption feeding device adsorbs and conveys the next batch of wiping parts, the wiping device can simultaneously pick up the wiping parts pre-placed by the receiving device, realizing the parallel operation of transfer feeding and wiping, and greatly improving the overall cycle time of the equipment.

[0008] In some embodiments of this application, the receiving box includes a bottom wall and a side wall connected to the bottom wall, the bottom wall having a recess; the wiping device includes a clamping mechanism, the clamping mechanism including a pressing member and clamping members located on both sides of the pressing member, the pressing member being used to press a portion of the wiping member down into the recess so that both ends of the wiping member form raised portions, and the two clamping members being used to clamp the raised portions.

[0009] By using the above technical solution, the wiping component is pressed down by the pressing component, causing the two ends of the wiping component to be raised. This not only makes it easier for the clamping component to hold the wiping component, but also ensures that the clamping mechanism only acts on the part of the wiping component above the recess and the two ends that are not involved in wiping, without contaminating other areas of the wiping component, thus improving the reliability of cleaning.

[0010] In some embodiments of this application, the receiving box has openings on both sides along the first direction.

[0011] The above technical solution has openings on both the receiving end and both sides to facilitate the opening and closing of the clamping mechanism.

[0012] In some embodiments of this application, the bottom wall is provided with a ridge, the ridge extends along the first direction and both ends protrude from the opening, and the ridge is provided with the recess in the middle.

[0013] By adopting the above technical solution, the concave part is set in the middle of the convex part. When the wiping part is pressed down by the pressing part, the convex part forms a fulcrum on both sides of the concave part. This not only guides the wiping part to produce a controllable lifting at both ends in the concave part, which is convenient for the clamping mechanism to clamp, but also the structure of the convex part suspends the main cleaning area of ​​the wiping part, reducing the contact area between the wiping part and the receiving box, thereby further reducing the risk of contamination and improving the reliability and consistency of cleaning.

[0014] In some embodiments of this application, the unwinding device further includes a tensioning mechanism located between the tray and the dragging mechanism, and used for the wiping member to pass through.

[0015] By adopting the above technical solution, the wiping parts are tensioned using a tensioning mechanism, which facilitates subsequent cutting operations and improves the dimensional consistency of multiple wiping parts after cutting.

[0016] In some embodiments of this application, the tensioning mechanism includes a first mounting member, a roller frame, and a tensioning roller. The roller frame is mounted on the first mounting member, and the tensioning roller is mounted on the roller frame in a manner rotatable about its own axial direction. A gap is formed between the tensioning roller and the first mounting member for the wiping member to pass through. The tensioning roller is configured to be able to approach or move away from the first mounting member on the roller frame to adjust the size of the gap.

[0017] By adopting the above technical solution, the tensioning roller is designed to be close to or far from the first mounting component to adjust the gap size, which not only facilitates material feeding, but also makes it easier to tension wiping components of different thicknesses.

[0018] In some embodiments of this application, the roller frame is provided with a guide groove, the guide groove extends obliquely relative to the first direction, the end of the tension roller is slidably connected to the guide groove, the roller frame is slidably connected to the first mounting member along the first direction, and the sliding of the roller frame along the first direction causes the tension roller on the guide groove to move closer to or away from the first mounting member.

[0019] By adopting the above technical solution, the gap between the tensioning roller and the first mounting component can be adjusted by sliding the roller frame. The structure is compact and easy to operate.

[0020] In some embodiments of this application, the tensioning mechanism further includes an elastic reset component, which is mounted on the first mounting member and connected to the roller frame. The elastic reset component is used to drive the roller frame to reset to the initial position, where the gap is minimized when the roller frame is in the initial position.

[0021] By adopting the above technical solution, the elastic reset component can keep the adjusted roller frame in the initial position without manual reset, so that the tensioning mechanism is always in a tensioned state.

[0022] In some embodiments of this application, the cutting device includes a first moving drive mechanism and a cutting mechanism. The cutting mechanism is mounted on the first moving drive mechanism and is used to cut the wiping component. The first moving drive mechanism is used to drive the cutting mechanism to move along a second direction, which intersects with the first direction and with the arrangement direction of the adsorption feeding device to the receiving device.

[0023] Using the above technical solution, when cutting is required, the first moving drive mechanism drives the cutting mechanism to move toward the wiping piece, and the cutting mechanism enters the cutting position to perform the cutting operation. After the cutting is completed, the first moving drive drives the cutting mechanism to retract, so as to facilitate the subsequent adsorption and feeding device to move the cut wiping piece.

[0024] In some embodiments of this application, the adsorption feeding device includes a second moving drive mechanism, which is used to drive a plurality of adsorption mechanisms to move along a first direction and rise and fall along a third direction. The adsorption mechanisms are used to adsorb the wiping component, and the third direction is the arrangement direction from the adsorption feeding device to the unwinding device.

[0025] By adopting the above technical solution, the second moving drive mechanism drives the adsorption mechanism to move along the first direction and the third direction, which facilitates the adsorption mechanism to adsorb the wiping parts and put the wiping parts into the receiving device.

[0026] In some embodiments of this application, the second moving drive mechanism includes a first lifting component, a first track, and a plurality of first sliding members. The first track is mounted on the first lifting component, and the first lifting component is used to drive the first track to move up and down along the third direction. The first track extends along the first direction, and the plurality of first sliding members are mounted on the first track in a sliding manner along the first direction. The plurality of adsorption mechanisms are mounted one by one on the plurality of first sliding members.

[0027] By adopting the above technical solution, multiple first sliding members drive multiple adsorption mechanisms to slide along the first direction, which not only facilitates the transfer of adsorption mechanisms between the unwinding device and the receiving device, but also allows the spacing between adjacent first sliding members along the first direction to be adjusted by moving multiple first sliding members in different sequences, so that the spacing of multiple adsorption mechanisms can be adjusted to adapt to the unwinding device and the receiving device.

[0028] In some embodiments of this application, the wiping device includes a third moving drive mechanism and a plurality of clamping mechanisms. The third moving drive mechanism is used to drive the plurality of clamping mechanisms to move along a second direction and to rise and fall along a third direction. The clamping mechanisms are used to clamp the cut wiping piece. The second direction intersects the first direction and the third direction. The third direction is the arrangement direction from the adsorption feeding device to the unwinding device.

[0029] By adopting the above technical solution, the third driving mechanism is used to drive the wiping component to move along the first direction and the third direction. This not only enables the wiping component to be picked up, but also allows the wiping component to be moved above the liquid injection port for wiping operations.

[0030] In some embodiments of this application, the third moving drive mechanism includes a second track, a second slider, and a second lifting assembly. The second slider is mounted on the second track and is capable of moving along the second direction on the second track. The second lifting assembly is mounted on the second slider. A plurality of the clamping mechanisms are mounted on the second lifting assembly and are lifted and lowered under the drive of the second lifting assembly.

[0031] By adopting the above technical solution, the clamping mechanism can move along the second direction by sliding the second slider on the second track, and the clamping mechanism can move along the third direction by lifting the second lifting component. The structure is simple and can realize the movement of the clamping mechanism in multiple degrees of freedom.

[0032] In some embodiments of this application, the wiping device further includes a plurality of rotating components, all of which are mounted on the second lifting component. The clamping mechanism is connected to the rotating components, and the rotating components are used to drive the clamping mechanism to rotate about an axis extending along the third direction.

[0033] By adopting the above technical solution, the rotating component can drive the wiping component on the clamping mechanism to rotate and wipe, thereby improving cleaning efficiency and effectiveness.

[0034] In some embodiments of this application, the battery cleaning device further includes a first detection device for detecting whether the clamping mechanism is in a state of clamping the wiping component.

[0035] By adopting the above technical solution, the first detection device is used to detect whether the clamping mechanism is clamping the wiping part, thereby reducing the possibility that the clamping mechanism will clean without load.

[0036] In some embodiments of this application, the battery cleaning device further includes a dripping device for adding cleaning fluid to the wiping element within the receiving device.

[0037] By adopting the above technical solution, cleaning solution is added to the wiping parts through a dripping device, thereby improving the cleaning effect of the wiping parts.

[0038] In some embodiments of this application, the dripping device includes a fourth moving drive mechanism and a dripping mechanism. The dripping mechanism includes a plurality of dripping heads, which are mounted on the fourth moving drive mechanism. The fourth moving drive mechanism is used to drive the plurality of dripping heads to move along a second direction, which intersects with the first direction and with the arrangement direction from the adsorption feeding device to the receiving device.

[0039] Using the above technical solution, when dripping is required, the fourth moving drive mechanism drives the dripping head to move above the receiving device to drip. After dripping is completed, the fourth moving drive mechanism drives the dripping head to retract, reducing interference with the wiping device's work of picking up the wiped parts.

[0040] In some embodiments of this application, the dripping mechanism further includes a second mounting component and an infusion pump. The second mounting component is located above the wiping device and the adsorption feeding device, and the infusion pump is mounted on the second mounting component and connected to a plurality of dripping head pipelines.

[0041] By adopting the above technical solution, the infusion pump and the second mounting component are positioned above the wiping device and the adsorption feeding device, so that the infusion pump will not interfere with the wiping device and the adsorption feeding device.

[0042] In some embodiments of this application, a recycling device is also included, wherein the wiping device is movable to the recycling device for recycling the wiping item after wiping.

[0043] By adopting the above technical solution, the wiping parts can be recycled using a recycling device, reducing the pollution to the surrounding environment caused by the random disposal of wiping parts. Moreover, the wiping parts can be recycled and reused, which is energy-saving and environmentally friendly.

[0044] In some embodiments of this application, the recycling device includes a pneumatic collection mechanism and a collection container connected together. The pneumatic collection mechanism is provided with an inlet, and the pneumatic collection mechanism can introduce the wiping component from the inlet into the collection container by airflow.

[0045] The above technical solution utilizes a pneumatic collection mechanism to introduce the wiping component into the collection container, resulting in a simple structure and rapid collection.

[0046] In some embodiments of this application, the collection container includes a container body and a collection drawer, wherein the collection drawer is installed in a pull-out manner on the container body and is used to collect the wiping device.

[0047] By adopting the above technical solution, the collection container is designed to include a pull-out collection drawer, which facilitates the cleaning of waste inside the collection container.

[0049] By adopting the above technical solution, the stacking height of the wiping components is detected by the second detection device. When the stacking height of the wiping components reaches the threshold, a warning message is issued to reduce the possibility that excessively high stacking of wiping components will affect the subsequent recycling of wiping components.

[0050] Secondly, embodiments of this application provide a battery production system, including battery cleaning equipment as described in any of the above technical solutions.

[0055] 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.

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.

[0057] 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.

[0058] 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.

[0060] 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.

[0061] In this application, "multiple" means two or more (including two).

[0062] The embodiments of this application will now be described in detail.

[0063] Currently, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace, among other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0064] During the production of battery devices, electrolyte needs to be injected into the battery cells through the injection port. However, electrolyte residue will remain at the injection port. The electrolyte dehydrates and crystallizes, causing dirt to the injection port of the battery cell and affecting the quality of subsequent sealing processes. Therefore, it is necessary to clean the residual electrolyte in a timely manner.

[0065] Existing cleaning equipment has two main approaches: one uses a conveyor belt to absorb the electrode liquid, but it cannot effectively remove the electrolyte crystallized at the injection port. The other approach cuts the conveyor belt and uses grippers to pick up and wipe the cut belt, but the transfer and conveying of the belt after cutting is difficult to maintain the stability of the belt position and is inefficient.

[0066] Therefore, how to provide a cleaning device that can effectively clean the electrolyte at the injection port and has high cleaning efficiency is an important issue in battery production and processing.

[0067] In view of this, this application provides a technical solution, which uses an adsorption feeding device to adsorb and fix the pulled-out wiping part, then the adsorption feeding device puts the wiping part cut by the cutting device into the receiving device for transfer, and finally uses the wiping device to pick up the wiping part to clean the battery filling port, thereby solving the above-mentioned technical problems.

[0068] The following is in conjunction with the appendix Figure 1-11 The battery cleaning device 100 provided in the embodiments of this application will be described.

[0069] Combined with appendix Figure 1 and attached Figure 2As shown, this embodiment provides a battery cleaning device 100, including an unwinding device 10, a cutting device 20, an adsorption feeding device 30, a receiving device 40, and a wiping device 50. The unwinding device 10 includes a material tray 11 and a dragging mechanism 12. The material tray 11 is used to carry the rolled wiping parts, and the dragging mechanism 12 is used to pull the wiping parts out of the material tray 11. The cutting device 20 is used to cut the wiping parts pulled out by the dragging mechanism 12. The adsorption feeding device 30 is located above the unwinding device 10 and is used to adsorb the wiping parts pulled out by the dragging mechanism 12 and transport the cut wiping parts. The receiving device 40 is arranged with the dragging mechanism 12 along a first direction X and is used to receive the wiping parts transported by the adsorption feeding device 30. The first direction X is the pulling direction of the wiping parts. The wiping device 50 is located above the unwinding device 10 and the receiving device 40 and is used to pick up the wiping parts in the receiving device 40 and drive the wiping parts to clean the battery filling port.

[0070] The battery cleaning device 100 of this embodiment also includes a frame 90, on which the unwinding device 10, cutting device 20, adsorption feeding device 30, receiving device 40 and wiping device 50 are all mounted.

[0071] In some embodiments, the unwinding device 10, the cutting device 20, and the adsorption feeding device 30 can be two sets, one of which is located on one side of the frame 90 along the first direction X, and the other is located on the other side of the frame 90 along the first direction X. The two sets of unwinding devices 10, cutting devices 20, and adsorption feeding devices 30 can increase the amount of wiping material supplied.

[0072] The receiving device 40 can simultaneously receive the material from two sets of unwinding devices 10, cutting devices 20 and adsorption feeding devices 30, and the wiping device 50 can simultaneously pick up the wiping parts from two sets of unwinding devices 10, cutting devices 20 and adsorption feeding devices 30, thereby enabling the simultaneous wiping of more battery cell inlets to improve cleaning efficiency.

[0073] Each unwinding device 10 may include one or more trays 11, on which the wiping material can be mounted in a roll. Taking the two trays 11 in the figure as an example, the two trays 11 can be detachably mounted on the frame 90, with one tray 11 for standby and the other tray 11 used for cleaning operations. After the wiping material on the current tray 11 is completely unwound, the other tray 11 can be moved to the conveying position.

[0074] The cutting device 20 is disposed facing the unwinding device 10. Specifically, the cutting device 20 and the unwinding device 10 may be arranged along the second direction Y. In some embodiments, the first direction X and the second direction Y may be two intersecting or even perpendicular horizontal directions, and the third direction Z is a vertical direction.

[0075] After the unwinding device 10 pulls out the strip-shaped wiping piece via the dragging mechanism 12, the cutting device 20 performs the cutting operation. The dragging mechanism 12 can be a gripper driven by a cylinder. Of course, the cylinder can also be replaced by other linear reciprocating motion structures, such as hydraulic cylinders, electric rods, and linear motors, etc., which will not be described in detail in this embodiment.

[0076] The relevant technology typically involves pressing the wiping part down through a pressing structure during the cutting process, picking it up through an adsorption structure, moving the adsorption structure to the loading position, clamping the wiping part with grippers, and finally wiping it.

[0077] The above process has many problems. For example, in the above process, it is difficult to maintain the stability of the wiping part's posture and the accuracy of its positioning during the pressing and picking process, making it difficult to accurately move the wiping part to the loading position for the gripper to pick up.

[0078] For example, in the aforementioned process of the related technology, when the gripper is gripping, the adsorption structure needs to cooperate with the gripper. The adsorption structure can only perform adsorption operation again after the gripper has completely gripped the wiping part. The gap period is long, which affects the cycle of cleaning operation.

[0079] Therefore, this embodiment is equipped with a receiving device 40, and the receiving device 40 and the unwinding device 10 can be arranged on the frame 90 along the first direction X in the figure.

[0080] After the adsorption and feeding device 30 in this embodiment adsorbs and picks up the cut wiping piece, it can move directly towards the wiping piece again to prepare for the next auxiliary cutting of the wiping piece and the subsequent feeding. At the same time, the wiping device 50 in this embodiment can directly clamp the wiping piece in the receiving device 40 to perform the wiping operation.

[0081] This structure and operating method frees the adsorption and feeding device 30 and the wiping device 50 from their forced operation, allowing them to operate independently and greatly improving work efficiency.

[0082] Moreover, there is no need to press down the wiping part, as the wiping part has already been adsorbed by the adsorption and feeding device 30 during the cutting process. Therefore, during the process of transporting the wiping part to the receiving device 40 after cutting, it can always maintain the stability of its posture and the accuracy of its positioning after movement, which is beneficial to the subsequent picking up by the wiping device 50.

[0083] Combined with appendix Figure 3 and attached Figure 4 As shown, in some examples, optionally, the receiving device 40 includes a plurality of receiving boxes 41 arranged at intervals along the first direction X, and the adsorption feeding device 30 is used to place the multiple cut wiping pieces one by one into the plurality of receiving boxes 41.

[0084] Multiple receiving boxes 41 are arranged at intervals along the first direction X. The number of receiving boxes 41, the number of cut wiping pieces, and the number of adsorption mechanisms 32 of the adsorption feeding device 30 are matched accordingly. For example, if there are a total of six wiping pieces cut by the cutting devices 20 on the left and right sides, then the number of receiving boxes 41 can also be six (of course, it can be more), and the number of adsorption mechanisms 32 is also six.

[0085] Multiple adsorption mechanisms 32 firmly hold the wiping parts before the cutting device 20 cuts them, and after cutting, the multiple wiping parts are transported one by one to multiple receiving boxes 41.

[0086] The structure of the receiving box 41 is not limited. For example, it can be a box structure with an open top or a structure similar to a groove.

[0087] By setting multiple receiving boxes 41, the adsorption feeding device 30 can pre-place multiple wiping parts at the same time. When the adsorption feeding device 30 adsorbs and conveys the next batch of wiping parts, the wiping device 50 can simultaneously pick up the wiping parts pre-placed by the receiving device 40, realizing the parallel operation of transfer feeding and wiping, and greatly improving the overall cycle time of the equipment.

[0088] Combined with appendix Figure 5 and 9 As shown, in some examples, optionally, the receiving box 41 includes a bottom wall 411 and a side wall 412 connected to the bottom wall 411, the bottom wall 411 having a recess 4112; the wiping device 50 includes a clamping mechanism 51, the clamping mechanism 51 including a pressing member 511 and clamping members 512 located on both sides of the pressing member 511, the pressing member 511 is used to press a portion of the wiping member down to the recess 4112 so that both ends of the wiping member form raised portions, and the two clamping members 512 are used to clamp the raised portions.

[0089] The bottom wall 411 is provided with a recess 4112, which can be a groove or a through hole or other structures. In some embodiments, the recess 4112 is located at the center of the bottom wall 411. This allows the wiping member to be subjected to more even force on both sides during the pressing process of the pressing member 511, making it easier to form the two ends that are raised, which is more conducive to the clamping of the clamping member 512.

[0090] The clamping mechanism 51 includes a third mounting member 513. The clamping member 512 and the pressing member 511 are both mounted on the third mounting member 513. The third mounting member 513 can be a cylindrical structure as shown in the figure.

[0091] The shape of the clamping members 512 is not limited. The opening and closing of the two clamping members 512 are used to clamp the wiping member and drive the wiping member to perform the liquid injection port operation. Furthermore, during the clamping and wiping process, the pressing member 511 also serves to limit the position of the wiping member. By pressing down the wiping member located above the recess 4112 by the pressing member 511, the wiping member is made to have both ends raised. This not only makes it easier for the clamping member 512 to clamp it, but also ensures that the clamping mechanism 51 only acts on the part of the wiping member above the recess 4112 and the two ends that do not participate in wiping, without contaminating other areas of the wiping member, thus improving the reliability of cleaning.

[0092] In some embodiments of this application, the receiving box 41 has openings on both sides along the first direction X.

[0093] The receiving box 41 has openings on both sides along the first direction X, or the openings can be directly provided on the side wall 412 of the receiving box 41. Alternatively, it can be as follows: Figure 5 As shown, the receiving box 41 has sidewalls 412 only on both sides along the second direction Y, while the receiving box 41 does not have sidewalls 412 on both sides along the first direction X. Both of these methods can form the opening structure described above.

[0094] The receiving box 41 has openings on both sides, which not only facilitates the opening and closing of the two grippers, but also allows the clamping mechanism 51 and the adsorption feeding device 30 to directly enter and exit the receiving box 41 from the opening along the first direction X, reducing the possibility of interference.

[0095] Combined again with the appendix Figure 5 As shown, in some examples, optionally, the bottom wall 411 is provided with a protrusion 4111, the protrusion 4111 extends along the first direction X and both ends extend out of the opening of the receiving box 41, and the protrusion 4111 is provided with a recess 4112 in the middle.

[0096] The ridge 4111 refers to a ridge structure that extends along the first direction X on the bottom wall 411. The width of the ridge 4111 along the second direction Y is much smaller than the width of the bottom wall 411 in the second direction Y. The length of the ridge 4111 along the first direction X can be greater than or equal to the length of the bottom wall 411 in the first direction X.

[0097] The protruding rib 4111 is located at the middle position of the bottom wall 411 along the second direction Y. Specifically, the center line of the protruding rib 4111 along the second direction Y may coincide with the center line of the bottom wall 411 along the second direction Y.

[0098] The protruding rib 4111 can be integrally formed with the bottom wall 411, or it can be installed on the bottom wall 411 by welding, plugging or other processes.

[0099] The recess 4112 is located in the middle of the convex rib 4111, which means that the center of the recess 4112 is located on the center line of the convex rib 4111 along the first direction X.

[0100] With this structural design, when the wiping component is pressed down by the pressing part, the protrusion 4111 forms a fulcrum on both sides of the recess 4112, which can guide the wiping component to produce a controllable lifting at both ends in the recess 4112, making it convenient for the clamping mechanism 51 to clamp it.

[0101] In addition, the raised rib 4111 increases the height of the wiping component, facilitating the feeding of the adsorption and feeding device and the retrieval of the clamping mechanism 51. Moreover, the raised rib 4111 elevates the main cleaning area of ​​the wiping component, reducing the contact area between the wiping component and the receiving box 41, thereby further reducing the risk of contamination and improving the reliability and consistency of cleaning.

[0102] Combined with appendix Figure 4 and attached Figure 6 As shown, in some examples, the unwinding device 10 may optionally include a tensioning mechanism 13 located between the tray 11 and the dragging mechanism 12, and used for the wiping element to pass through.

[0103] The reason for configuring the tensioning mechanism 13 is that the cutting device 20 needs to cut multiple wiping pieces at once, which requires the dragging mechanism 12 to pull the rolled wiping pieces out to a certain length. Since the material tray 11 can rotate, it is difficult to maintain the tension of the pulled-out wiping pieces, which will result in the wiping pieces being of different lengths.

[0104] Therefore, this embodiment is equipped with a tensioning mechanism 13. The stretched and uncut wiping piece passes through the tensioning mechanism 13 and is tensioned by the tensioning mechanism 13, so that the stretched and cut piece can maintain a tensioned state.

[0105] The tensioning mechanism 13 can have various structural forms, such as including two tensioning wheels (this embodiment is not shown in the figure), or multiple tensioning rollers 133, etc.

[0106] In this embodiment, the tensioning mechanism 13 is used to tension the wiping parts, which facilitates the subsequent cutting operation and improves the dimensional consistency of multiple wiping parts after cutting.

[0107] In some examples, the tensioning mechanism 13 may optionally include a first mounting member 131, a roller frame 132, and a tensioning roller 133, the roller frame 132 being mounted on the first mounting member 131, the tensioning roller 133 being mounted on the roller frame 132 in a manner rotatable about its own axial direction, a gap being formed between the tensioning roller 133 and the first mounting member 131 for the wiping member to pass through, and the tensioning roller 133 being configured to be able to approach or move away from the first mounting member 131 on the roller frame 132 to adjust the size of the gap.

[0108] The first mounting component 131 can be a plate-shaped component or a block-shaped component as shown in the figure. The first mounting component 131 can be fixedly installed on the frame 90 or installed on the first frame 90 in a way that allows for position adjustment.

[0109] The roller frame 132 is mounted on the first mounting member 131. In some embodiments, each roller frame 132 includes two first mounting plates 1321 and a connecting plate 1322. The two first mounting plates 1321 are arranged parallel to each other along the second direction Y and are connected by the connecting plate 1322.

[0110] The tension roller 133 is located between two first mounting plates 1321. Both ends of the tension roller 133 are mounted on the two first mounting plates 1321, and it can rotate around its own axis on the first mounting plates 1321.

[0111] The tensioning mechanism 13 also includes a cover plate 135 mounted on the roller frame 132, which is used to protect the roller frame 132 and the wiping component.

[0112] In this embodiment, the first mounting component 131 is equipped with two roller frames 132 and four tension rollers 133. One roller frame 132 is paired with two tension rollers 133, which can tension two different wiping components.

[0113] Considering that the gap needs to be increased before the wiping component is installed to the tensioning mechanism 13 so that the end of the wiping component can pass through the tensioning mechanism 13, this embodiment designs the tensioning roller 133 to be able to adjust the gap size by being close to or away from the first mounting component 131. This not only makes it convenient to place the wiping component, but also facilitates the tensioning of wiping components of different thicknesses, thus improving the versatility of the equipment.

[0114] In some examples, optionally, the roller frame 132 is provided with a guide groove 1323, the guide groove 1323 extends obliquely relative to the first direction X, the end of the tension roller 133 is slidably connected to the guide groove 1323, the roller frame 132 is slidably connected to the first mounting member 131 along the first direction X, and the sliding of the roller frame 132 along the first direction X causes the tension roller 133 on the guide groove 1323 to move closer to or away from the first mounting member 131.

[0115] Both first mounting plates 1321 are provided with guide grooves 1323. The length direction of the guide grooves 1323 is inclined relative to the first direction X and inclined relative to the third direction Z. However, the length direction of the guide grooves 1323 can be perpendicular to the second direction Y.

[0116] When it is necessary to increase the gap along the third direction Z, the roller frame 132 is pushed in the direction close to the dragging mechanism 12. At this time, the tension roller 133 moves upward along the guide groove 1323, thereby widening the gap to facilitate the installation of the wiping component.

[0117] Tensioning of the wiping component is achieved by reducing the gap size along the third direction Z, thereby reducing the gap size.

[0118] This adjustment structure can adjust the gap between the tension roller 133 and the first mounting part 131 by sliding the roller frame 132. It is not only compact in structure, but also easy to operate as it only requires manual operation or by driving the roller frame 132 to move along the first direction X through a linear motion structure.

[0119] In some examples, the tensioning mechanism 13 may optionally include an elastic reset assembly 134, which is mounted on the first mounting member 131 and connected to the roller frame 132. The elastic reset assembly 134 is used to drive the roller frame 132 back to the initial position, where the gap size is minimized when the roller frame 132 is in the initial position.

[0120] The elastic reset assembly 134 includes an elastic element 1341 and a mounting block 1342. The mounting block 1342 and the connecting plate 1322 are arranged at intervals along the first direction X. The mounting block 1342 is fixedly installed on the mounting component. One end of the elastic element 1341 is connected to the mounting block 1342, and the other end is connected to the connecting plate 1322.

[0121] When the elastic element 1341 is not subjected to external stress, the tension roller 133 is exactly at the bottom of the guide groove 1323, and the gap is the smallest at this time.

[0122] When the wiping component needs to be installed, the roller frame 132 is moved by external force, which stretches (or compresses) the elastic component 1341. At this time, the gap is widened, making it easier for the wiping component to pass through the gap.

[0123] Then the external force that drives the roller frame 132 to slide is removed. At this time, the elastic restoring force of the elastic element 1341 drives the roller frame 132 to slide back to the initial position, at which point the gap is minimal.

[0124] This structure, using the elastic reset component 134, allows the adjusted roller frame 132 to be in its initial position without manual reset or reset by other structures, ensuring that the tensioning mechanism 13 is always in a tensioned state.

[0125] Combined again with the appendix Figure 3 and attached Figure 4 As shown, in some embodiments, the cutting device 20 includes a first moving drive mechanism 21 and a cutting mechanism 22. The cutting mechanism 22 is mounted on the first moving drive mechanism 21 and is used to cut the wiping component. The first moving drive mechanism 21 is used to drive the cutting mechanism 22 to move along the second direction Y. The second direction Y intersects with the first direction X and with the arrangement direction of the adsorption feeding device 30 to the receiving device 40.

[0126] The first moving drive mechanism 21 can be a linear reciprocating motion structure such as a cylinder, hydraulic cylinder, or electric cylinder. The first moving drive mechanism 21 can drive the cutting mechanism 22 to move along the second direction Y.

[0127] Specifically, when cutting is required, the first moving drive mechanism 21 drives the cutting mechanism 22 to move toward the wiping piece, and the cutting mechanism 22 enters the cutting position to perform the cutting operation. After the cutting is completed, the first moving drive drives the cutting mechanism 22 to retract, so as to facilitate the subsequent adsorption and feeding device 30 to move the cut wiping piece.

[0128] In some embodiments, the cutting device 20 further includes a first moving guide mechanism 23, which and the first moving drive mechanism 21 are both mounted on the frame 90 and are arranged at intervals along the first direction X.

[0129] One end of the cutting mechanism 22 along the first direction is mounted on the first moving drive mechanism 21, and the other end of the cutting mechanism 22 is slidably mounted on the first moving guide mechanism 23.

[0130] The first moving guide mechanism 23 may include a guide post extending along the second direction Y, to which the cutting mechanism 22 is slidably connected. The first moving guide mechanism 23 can improve the stability of the cutting mechanism 22 during movement.

[0131] In some embodiments, the cutting mechanism 22 includes a plurality of cutting blades, which may be pneumatic scissors. The plurality of cutting blades are arranged at intervals along a first direction X, and the spacing between two adjacent cutting blades can be adjusted along the first direction X.

[0132] The spacing between two adjacent cutting blades is designed to be adjustable along the first direction X, thereby enabling the size of the cut wiping piece to be adjustable.

[0133] Combined again with the appendix Figure 4As shown, in some examples, optionally, the adsorption feeding device 30 includes a second moving drive mechanism 31 and a plurality of adsorption mechanisms 32. The second moving drive mechanism 31 is used to drive the plurality of adsorption mechanisms 32 to move along a first direction X and to rise and fall along a third direction Z. The adsorption mechanism 32 is used to adsorb the wiping piece. The third direction Z is the arrangement direction of the adsorption feeding device 30 to the unwinding device 10.

[0134] The second moving drive mechanism 31 can be a robotic arm, or it can be composed of the first lifting component 311, the first track 312 and the first sliding member 313 described below, as long as it can drive multiple adsorption mechanisms 32 to move along the first direction X and lift along the third direction Z.

[0135] During adsorption, the second moving drive mechanism 31 drives the adsorption mechanism 32 to descend along the third direction Z and approach the stretched wiping piece along the first direction X until the adsorption mechanism 32 is in a position where it can adsorb the wiping piece.

[0136] After the wiping piece is cut, the second moving drive mechanism 31 drives the adsorption mechanism 32 and the wiping piece to move to the feeding device, and puts the wiping piece into the receiving device 40.

[0137] In some examples, optionally, the second moving drive mechanism 31 includes a first lifting assembly 311, a first track 312, and a plurality of first sliding members 313. The first track 312 is mounted on the first lifting assembly 311, and the first lifting assembly 311 is used to drive the first track 312 to move up and down along a third direction Z. The first track 312 extends along a first direction X. The plurality of first sliding members 313 are mounted on the first track 312 in a sliding manner along the first direction X. A plurality of adsorption mechanisms 32 are mounted one by one on the plurality of first sliding members 313.

[0138] The first lifting component 311 can be a linear reciprocating motion structure such as a cylinder or hydraulic cylinder. The first lifting component 311 is used to drive the first track 312 to lift along the third direction Z.

[0139] The length of the first track 312 extends along the first direction X, and a plurality of first sliders 313 are slidably mounted on the first track 312. The first sliders 313 may be structures such as electric sliders.

[0140] Taking two adsorption feeding devices 30 as an example, only one first track 312 is needed to accommodate the installation of multiple first sliding parts 313 of the two adsorption feeding devices 30, and only one first lifting component 311 is needed to drive the two adsorption feeding devices 30 on both sides of the frame 90 to lift and lower, further simplifying the equipment structure.

[0141] Each of the multiple first sliding members 313 is independently controlled by the control device of the cleaning equipment, thereby enabling the multiple first sliding members 313 to slide on the first track 312 in different sequences.

[0142] The reason for adopting this design is that, in order to enable multiple clamping mechanisms 51 to match multiple battery cells, the center distance of multiple clamping mechanisms 51 is equal to the center distance of the liquid injection ports of two adjacent battery cells, and the center distance of multiple clamping mechanisms 51 is equal to the center distance of multiple receiving boxes 41. This makes it convenient for multiple clamping mechanisms 51 to clamp the wiping parts without adjusting their positions and to directly carry out cleaning operations.

[0143] If the spacing of the multiple first sliding members 313 is not adjustable along the first direction X, then the center distance of the multiple first sliding members 313 needs to be designed to be equal to the center distance of the multiple receiving boxes 41. In this way, not only does it increase the size of the adsorption and feeding device 30 in the first direction X, but in order to reduce the waste of wiping parts and the difficulty of placing the wiping parts in the receiving box 41, the size of the wiping parts after cutting should not be too large. The first sliding members 313 with such large spacing are difficult to match the adsorption of the cut wiping parts.

[0144] In other words, if multiple first sliding members 313 are designed to slide simultaneously along the first direction X and the spacing is not adjustable, increasing the spacing of multiple cutting blades can only increase the length of the wiping piece after cutting. This not only makes the equipment more bulky, but also makes it difficult for the wiping device 50 to clamp longer wiping pieces.

[0145] Therefore, in this embodiment, multiple first sliding members 313, which can slide along the first direction X at different times, drive multiple adsorption mechanisms 32 to slide along the first direction X. During adsorption before the wiping piece is cut, the distance between two adjacent first sliding members 313 is reduced, so that the multiple first sliding members 313 can match the length of the stretched wiping piece. When the cut wiping piece is transported to multiple receiving boxes 41, the distance between the multiple first sliding members 313 increases to match the distance between the multiple receiving boxes 41.

[0146] This structure not only facilitates the transfer of the adsorption mechanism 32 between the unwinding device 10 and the receiving device 40, but also allows the multiple first sliding members 313 to move in different sequences, thereby adjusting the spacing between adjacent first sliding members 313 along the first direction X. This allows the spacing of the multiple adsorption mechanisms 32 to be adjusted to adapt to the unwinding device 10 and the receiving device 40.

[0147] Combined with appendix Figures 7 to 9As shown, in some examples, optionally, the wiping device 50 includes a third moving drive mechanism 52 and a plurality of clamping mechanisms 51. The third moving drive mechanism 52 is used to drive the plurality of clamping mechanisms 51 to move along the second direction Y and to move up and down along the third direction Z. The clamping mechanisms 51 are used to clamp the cut wiping pieces. The second direction Y intersects with the first direction X and the third direction Z. The third direction Z is the arrangement direction of the adsorption feeding device 30 to the unwinding device 10.

[0148] The third moving drive mechanism 52 can be a structure such as a robotic arm or robotic hand, or it can be composed of the second track 521, the second sliding member 522 and the second lifting component 523, as long as it can drive the wiping member to move along the first direction X and the third direction Z.

[0149] In this way, not only can the wiping parts be picked up, but the wiping parts can also be moved to the top of the liquid injection port for wiping operations.

[0150] The clamping mechanism 51 includes two clamping members 512 arranged at intervals along the first direction X. The two clamping members 512 are rotatably mounted on the third moving drive mechanism 52. The clamping and releasing of the wiping member is achieved by the lower ends of the two clamping members 512 moving closer or further apart.

[0151] In some examples, optionally, the third moving drive mechanism 52 includes a second track 521, a second slider 522, and a second lifting assembly 523. The second slider 522 is mounted on the second track 521 and is capable of moving along the second direction Y on the second track 521. The second lifting assembly 523 is mounted on the second slider 522. A plurality of clamping mechanisms 51 are mounted on the second lifting assembly 523 and are lifted and lowered under the drive of the second lifting assembly 523.

[0152] The second track 521 extends along the second direction Y in the figure and is mounted on the top of the frame 90.

[0153] The second sliding member 522 can be a sliding structure such as an electric slider. Of course, a linear reciprocating motion structure (such as a cylinder, hydraulic cylinder, etc.) can also be used to replace the second track 521 and the second sliding member 522. In some embodiments, the second track 521 and the second sliding member 522 can also be a slider screw motor structure.

[0154] The second lifting component 523 can also be any linear reciprocating motion structure, which will not be listed one by one in this embodiment.

[0155] In this embodiment, the second slider 522 slides on the second track 521 to realize the movement of the clamping mechanism 51 along the second direction Y. The lifting and lowering of the second lifting component 523 drives the clamping mechanism 51 to move along the third direction Z. The structure is simple and can realize the movement of the clamping mechanism 51 with multiple degrees of freedom.

[0156] In some examples, the wiping device 50 may optionally include a plurality of rotating components 53, all of which are mounted on the second lifting component 523. The clamping mechanism 51 is connected to the rotating components 53, and the rotating components 53 are used to drive the clamping mechanism 51 to rotate about an axis extending in the third direction Z.

[0157] One rotating component 53 can drive a clamping mechanism 51 to rotate. At this time, multiple clamping mechanisms 51 are mounted on multiple rotating components 53. The rotating component 53 may include a rotating drive component 531 (e.g., a motor) that outputs torque.

[0158] It can also be like Figure 8 As shown, a rotating component 53 drives multiple (e.g., two) clamping mechanisms 51 to rotate. The rotating component 53 needs to include a rotating drive 531 and a transmission structure 532. The transmission structure 532 can be a gear transmission group. The rotating drive 531 is connected to the gear transmission group respectively. The two gears in the gear transmission group are respectively connected to the third mounting part 513 of the two clamping mechanisms 51, thereby driving the two clamping mechanisms 51 to rotate.

[0159] Of course, a rotary drive 531 can also drive more clamping mechanisms 51 to rotate through a transmission structure 532 (this embodiment is not shown in the figure).

[0160] In this way, the rotating component 53 can be used to drive the wiping component on the clamping mechanism 51 to rotate and wipe. Compared with the method of only driving the wiping component to move horizontally, the rotation wiping is more likely to remove the crystallized electrolyte, which can improve the cleaning efficiency and effect.

[0161] Combined with appendix Figure 12 As shown, in some embodiments, the battery cleaning device 100 further includes a first detection device 60, which is used to detect whether the clamping mechanism 51 is in the state of clamping the wiping component.

[0162] The first detection device 60 may include a color sensor 61 or an image acquisition structure (such as a camera). Taking the first detection device 60 as an example that includes multiple color sensors 61, the first detection device 60 includes a fourth mounting member 62 and multiple color sensors 61. The multiple color sensors 61 are mounted on the fourth mounting member 62 and located below the clamping mechanism 51. The multiple color sensors 61 detect whether the multiple clamping mechanisms 51 are clamping the wiping component.

[0163] Taking the first detection device 60 including an image acquisition structure as an example, the number of the first detection devices 60 includes one or more cameras, as long as they can acquire the image of the bottom of the clamping mechanism 51.

[0164] The detection principle of the two detection structures mentioned above is as follows: the control device determines whether the detected color matches the color of the wiping component pre-stored in the control device. If they match, the control device determines that the clamping mechanism 51 clamps the wiping component.

[0165] In addition, the testing process can be performed only when the clamping mechanism 51 moves toward the battery cell located at the middle position of the frame 90 along the second direction Y. During the cleaning and resetting process of the clamping mechanism 51, the testing device does not perform testing.

[0166] By using the first detection device 60 to detect whether the clamping mechanism 51 is clamping the wiping component, the possibility of the clamping mechanism 51 cleaning without load can be reduced.

[0167] Combined with appendix Figure 2 , 10 As shown in Figures 1 and 11, in some examples, the battery cleaning device 100 may optionally include a dripping device 70 for adding cleaning fluid to the wiping element within the receiving device 40.

[0168] The installation height of the dripping device 70 is higher than that of the receiving device 40 and the unwinding device 10. When the receiving device 40 includes multiple receiving boxes 41, the dripping device 70 includes multiple dripping heads 721. The multiple dripping heads 721 are used to add cleaning fluid to the wiping parts in the multiple receiving boxes 41 one by one, thereby improving the cleaning effect of the wiping parts.

[0169] In some examples, the dripping device 70 may optionally include a fourth moving drive mechanism 71 and a dripping mechanism 72. The dripping mechanism 72 includes a plurality of dripping heads 721, which are mounted on the fourth moving drive mechanism 71. The fourth moving drive mechanism 71 is used to drive the plurality of dripping heads 721 to move along a second direction Y, which intersects with the first direction X and with the arrangement direction of the adsorption feeding device 30 to the receiving device 40.

[0170] The fourth moving drive mechanism 71 can be any of the above-mentioned linear reciprocating motion structures. There can be two fourth moving drive mechanisms 71. Multiple drip heads 721 are installed on the fifth mounting member 724. Both ends of the fifth mounting member 724 can be installed on the two fourth moving drive mechanisms.

[0171] By using two fourth moving drive mechanisms 71 to simultaneously drive the fifth mounting component 724 and multiple drip heads 721 to move along the second direction Y, the stability of the fifth mounting component 724 during its movement is improved.

[0172] When dripping is required, the fourth moving drive mechanism 71 drives the dripping head 721 to move above the receiving device 40 to drip. After dripping is completed, the fourth moving drive mechanism 71 drives the dripping head 721 to retract, reducing interference with the wiping device 50's wiping item picking operation.

[0173] In some embodiments, the dripping mechanism 72 further includes a second mounting member 722 and an infusion pump 723. The second mounting member 722 is located above the wiping device 50 and the adsorption feeding device 30. The infusion pump 723 is mounted on the second mounting member 722 and is connected to a plurality of drip heads 721 via pipeline.

[0174] The second mounting component 722 can be a plate-shaped component. The number of infusion pumps 723 matches the number of drip heads 721, and multiple infusion pumps 723 are connected to multiple drip heads 721 through pipelines.

[0175] The second mounting component 722 is mounted on the top of the frame 90 and is located above the wiping device 50 and the adsorption feeding device 30.

[0176] This design is adopted because if the second mounting component 722 and the infusion pump 723 are located near the fifth mounting component 724, the size of the entire dripping device 70 along the second direction Y will be increased, and the operation of the wiping device 50 and the adsorption feeding device 30 will be easily interfered with.

[0177] Therefore, in this embodiment, the infusion pump 723 and the second mounting component 722 are positioned above the wiping device 50 and the adsorption feeding device 30, so that the infusion pump 723 will not interfere with the wiping device 50 and the adsorption feeding device 30, and the size of the device along the second direction Y is reduced.

[0178] Combined with appendix Figure 1 and 12 As shown, in some examples, the battery cleaning device 100 may optionally include a recycling device 80, to which the wiping device 50 is movable, and the recycling device 80 is used to recycle the wiped parts after wiping.

[0179] The battery cell conveyor line can be located in the middle of the frame 90 along the second direction Y, and below the second track 521, with the recycling device 80 located at... Figure 1 It is located on the front side of the frame 90 and below the wiping device 50.

[0180] After wiping by wiping device 50, towards Figure 1 The front side of the frame 90 moves to below the recycling device 80, and then releases the clamp on the wiping piece, allowing the wiping piece to fall into the recycling device 80.

[0181] The recycling device 80 can be a recycling box or a wiping device including the pneumatic collection mechanism 81 and the collection container 82 described below, as long as it can receive the waste gas.

[0182] The recycling device 80 collects the wiping parts, reducing the pollution caused by the random disposal of wiping parts to the surrounding environment. It also enables the recycling and reuse of wiping parts, which is energy-saving and environmentally friendly.

[0183] In some examples, the recycling device 80 may optionally include a pneumatic collection mechanism 81 and a collection container 82 connected together. The pneumatic collection mechanism 81 is provided with an inlet 811, which is capable of introducing the wiping material from the inlet 811 into the collection container 82 by airflow.

[0184] The pneumatic collection mechanism 81 may include a cavity and multiple pneumatic air knives. The cavity has openings at the top and bottom and its width gradually decreases from top to bottom. The pneumatic air knives are installed at the openings of the cavity, and the lower side of the cavity is connected to the collection container 82.

[0185] When the clamping mechanism 51 moves to the opening of the cavity, the clamping mechanism 51 releases its grip on the wiping piece, and the pneumatic air knife blows the wiping piece into the cavity, eventually falling into the collection container 82.

[0186] This structure uses a pneumatic collection mechanism 81 to introduce the wiping component into the collection container 82. It has a simple structure and can collect quickly.

[0187] In some examples, the collection container 82 may optionally include a container body 821 and a collection drawer 822, which is installed in a pull-out manner on the container body 821 and is used to collect the wiping items.

[0188] The collection container 82 is designed to include a pull-out collection drawer 822 for easy cleaning of waste inside the collection container 82.

[0189] In some examples, optionally, the battery cleaning device 100 also includes a control device (not shown), and a second detection device (not shown) is installed in the collection container 82. The second detection device is signal-connected to the control device and is used to detect the stacking height of the wiping components in the collection container 82. The control device issues a warning message when the stacking height of the wiping components reaches a threshold.

[0190] The control device can be a processor or controller (including control circuits such as PLC), and the second detection device can be a vision detection device or a distance detection device.

[0191] The second detection device detects the stacking height of the wiping items. When the stacking height of the wiping items reaches the threshold, the control device controls the alarm (not shown in the figure) to issue a warning message, reducing the possibility that the excessive stacking of wiping items will affect the subsequent recycling of wiping items.

[0192] Based on the battery cleaning device 100 described above, this embodiment provides a battery production system, including the battery cleaning device 100 as described in any of the above technical solutions. The battery production system may also include a battery conveying device for conveying individual battery cells.

[0193] Combined with appendix Figure 13 As shown, this embodiment also provides a battery cleaning method, including the following steps: The unwinding device 10 carries the rolled wiping component on the tray 11, and the dragging mechanism 12 pulls the wiping component on the tray 11 out along the first direction X.
