[0001] This disclosure claims priority to the Chinese patent application filed with the Patent Office of China on November 21, 2023, with application number 202323153121.3 and application name “Wiping Device and Wiping System,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to a wiping device and a wiping system. Background Art

[0003] When manufacturing lithium batteries, electrolyte needs to be injected into the battery through the injection port. After the injection is completed, some electrolyte will remain in the injection port. This residual electrolyte can affect the subsequent processes, such as the welding yield of the sealing pin in the next process. To ensure the welding effect of the sealing pin, the residual electrolyte needs to be wiped clean before welding the sealing pin.

[0004] Typically, residual electrolyte at the injection port is removed using a wiping mechanism. Traditionally, this mechanism uses vacuum suction to absorb a cleaning medium, which then rotates to wipe the electrolyte. However, this method can easily clog the vacuum line, requiring regular cleaning. This makes maintenance difficult and limits production efficiency.

[0016] In one embodiment, the material holder is provided with a pressure portion. When the feeding member moves relative to the material holder along the first direction, the cleaning medium is folded under the action of the pressure portion to form a folded portion. The clamping member cooperates with the wiping member to clamp the folded portion of the cleaning medium.

[0017] In one embodiment, the wiping member is movably connected to the mounting seat along the first direction, and the clamping member is hinged to the mounting seat and connected to the wiping member;

[0060] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0061] 1-3 , an embodiment of the present disclosure provides a wiping system 1000 for wiping the electrolyte at the liquid filling port of a battery to prevent the electrolyte from affecting the normal progress of subsequent processes, such as preventing residual electrolyte from affecting the welding of sealing pins and causing cold welding of the sealing pins.

[0062] Referring to Figure 4 , the wiping system 1000 includes a liquid injection device 100 , which is used to inject a cleaning liquid into the battery's liquid injection port. The cleaning liquid soaks up any electrolyte remaining in the port, thereby dissolving any crystallized electrolyte on the battery. Typically, the cleaning liquid is diethyl carbonate (DEC) or dimethyl carbonate (DMC).

[0063] The liquid injection device 100 includes a liquid reservoir 101, a liquid injection driver 102, and a liquid injection needle 103. The liquid reservoir 101 is used to store cleaning liquid, and the liquid injection driver 102 is used to drive the cleaning liquid in the liquid reservoir 101 to be injected into the liquid injection port through the liquid injection needle 103. In some embodiments, the liquid injection driver 102 is a dispensing valve that can cause the cleaning liquid in the liquid reservoir 101 to flow toward the liquid injection needle 103, thereby injecting the cleaning liquid into the liquid injection port of the battery.

[0064] Continuing with FIG1 , the wiping system 1000 includes at least one wiping device 200. The wiping device 200 includes a feeding mechanism 10 and a wiping mechanism 20. The feeding mechanism 10 is used to provide a cleaning medium 2000. The wiping mechanism 20 can pick up and clamp the cleaning medium 2000 from the feeding mechanism 10. When the wiping mechanism 20 drives the cleaning medium 2000 to rotate, it can wipe the injection port after the cleaning liquid is injected by the injection device 100. That is, in the conveying direction of the battery, the station where the wiping mechanism 20 wipes the electrolyte is located downstream of the station where the injection device 100 injects the cleaning liquid. This allows the cleaning liquid to fully dissolve the crystallized electrolyte. The wiping mechanism 20 then drives the cleaning medium 2000 to rotate to wipe the electrolyte, ensuring a good wiping effect.

[0065] It should be noted that in some specific embodiments, the wiping mechanism 20 may include a driving member, which drives the rotation of the clamping portion of the wiping mechanism 20 for clamping the cleaning medium 2000, thereby driving the cleaning medium 2000 to rotate and wipe the electrolyte. In other embodiments, the wiping mechanism 20 may not include a driving member, but rather an external driving member may be used to drive the wiping mechanism 20 to rotate, thereby driving the cleaning medium 2000 to rotate and wipe the electrolyte.

[0066] In some embodiments, the wiping system 1000 includes multiple liquid injection devices 100 and multiple wiping devices 200 (see Figures 5-7). The number of liquid injection devices 100 and wiping devices 200 is equal and corresponds one to one. In this way, after the multiple liquid injection devices 100 inject the dissolving liquid into the multiple batteries, the multiple wiping devices 200 can wipe the multiple batteries after the dissolving liquid is injected, so as to improve the working efficiency.

[0067] In some embodiments, referring to Figures 8-12 , the feeding mechanism 10 includes a material holder 11 and a feeding member 12. The feeding member 12 is movably disposed on the material holder 11 along a first direction and is used to hold the cleaning medium 2000. In some embodiments, the feeding member 12 is provided with suction holes, through which the cleaning medium 2000 is adsorbed onto the feeding member 12. Specifically, the feeding member 12 has a disc-shaped adsorption portion, with the adsorption holes disposed on the adsorption portion, through which the adsorption portion adsorbs the cleaning medium 2000. It is contemplated that in other embodiments, the adsorption holes may be omitted from the feeding member 12, in which case the cleaning medium 2000 is supported on the feeding member 12 by gravity.

[0068] Referring to Figures 13 and 14 , the wiping mechanism 20 includes a mounting base 21, a wiping member 22, and a clamping member 23. Both the wiping member 22 and the clamping member 23 are mounted on the mounting base 21. The wiping member 22 can be controlled to push the feed member 12 in a first direction. That is, the wiping member 22 can apply a force to the feed member 12 in the first direction. After being subjected to this force, the feed member 12 moves in the first direction relative to the feed base 11. During the movement of the feed member 12 in the first direction relative to the feed base 11, the cleaning medium 2000 is wrapped around the wiping member 22. Thereafter, the clamping member 23 cooperates with the wiping member 22 to clamp the cleaning medium 2000. It should be noted that the cleaning medium 2000 is wrapped around the side of the wiping member 22, and the clamping member 23 cooperates with the wiping member 22 to clamp the cleaning medium 2000 from the side.

[0069] In the wiping system 1000 provided by the embodiment of the present disclosure, the clamping member 23 of the wiping mechanism 20 cooperates with the wiping member 22 to clamp the cleaning medium 2000. Compared with the method of using vacuum adsorption to adsorb the cleaning medium 2000 onto the wiping mechanism 20 in the related art, there is no need to set a vacuum air path on the wiping mechanism 20, so there is no problem of air path blockage. The wiping mechanism 20 is easy to maintain, which saves maintenance time and thus improves production efficiency.

[0070] In some embodiments, the material holder 11 is provided with a pressure portion. When the material feed member 12 moves relative to the material holder 11 in a first direction, the cleaning medium 2000 is folded under the action of the pressure portion to form a folded portion. The clamping member 23 and the wiper 22 cooperate to clamp the folded portion of the cleaning medium 2000. Specifically, when the wiper 22 presses down on the cleaning medium 2000 in the first direction, the pressure portion can apply a force to the cleaning medium 2000. Under the action of the pressure portion, the cleaning medium 2000 folds and wraps around the side of the wiper 22. The clamping member 23 clamps the cleaning medium 2000 to the wiper 22 after the folded cleaning medium 2000. This arrangement facilitates wrapping the sheet of cleaning medium 2000 around the wiper 22, thereby facilitating the clamping member 23 and the wiper 22 to cooperate in clamping the cleaning medium 2000. Typically, the cleaning medium 2000 is a non-woven fabric sheet or a dust-free cloth sheet.

[0071] In other embodiments, the pressure-applying portion of the material holder 11 may be omitted. For example, when the cleaning medium 2000 is a cylindrical structure, the wiper 22 can be inserted into the cleaning medium 2000 through the opening of the cylindrical structure. At this time, the cleaning medium 2000 can also be wrapped around the wiper 22.

[0072] In one embodiment, the material holder 11 is provided with a mounting hole, and the feed member 12 is mounted within the mounting hole of the material holder 11. The feed member 12 can extend from the mounting hole or retract into the mounting hole. Specifically, when the feed member 12 extends from the mounting hole, the cleaning medium 2000 is supported on the feed member 12. When the wiper 22 applies pressure to the feed member 12 in a first direction, the feed member 12 retracts into the mounting hole, and the edge of the mounting hole forms the aforementioned pressure-applying portion.

[0073] It is conceivable that in other embodiments, the mounting hole of the material holder 11 may be omitted, and the feeding member 12 may be mounted on the material holder 11 by other means.

[0074] Furthermore, the material holder 11 is cylindrical, with the mounting hole axially defined therein. The axial direction of the material holder 11 is parallel to the first direction. To match the shape of the material holder 11, the feed member 12 is a multi-stage disc-shaped structure. It should be understood that in other embodiments, the shapes of the material holder 11 and the feed member 12 are not limited.

[0075] Continuing to refer to Figure 9, the feeding mechanism 10 also includes a reset member 13, which is arranged between the feeding member 12 and the material holder 11. When the wiping member 22 pushes the feeding member 12, causing the feeding member 12 to move relative to the material holder 11 in the first direction, the reset member 13 stores energy. When the wiping member 22 releases the feeding member 12, the feeding member 12 is reset under the action of the reset member 13. With this arrangement, when the wiping member 22 releases the feeding member 12, the feeding member 12 can automatically reset under the action of the reset member 13, avoiding the need to manually reset the feeding member 12, thereby further improving production efficiency. Specifically, the reset member 13 is a spring. Of course, in some other embodiments, the reset member 13 can also be an elastic component such as rubber.

[0076] The feeding mechanism 10 further includes a guide member, which is used to guide the feeding member 12 along the first direction when the feeding member 12 moves relative to the material holder 11. The guide member is provided to prevent the feeding member 12 from deviating when moving relative to the material holder 11 along the first direction.

[0077] In some embodiments, the guide member includes a linear bearing 14, through which the feed member 12 is mounted on the material base 11. The linear bearing 14 is used to guide the feed member 12 in the first direction. In other embodiments, the guide member also includes a guide rod and a mating portion, one of which is provided on the material base 11, and the other is provided on the feed member 12. The guide rod is movable along the first direction through the mating portion to guide the feed member 12. Specifically, the mating portion is a guide hole. In this way, the dual coordination of the linear bearing 14, the guide rod, and the mating portion ensures that the feed member 12 does not deviate when moving relative to the material base 11 in the first direction.

[0078] Furthermore, the reset member 13 is a spring. The guide member includes a first guide rod 15 and a first mating portion that cooperate with each other, and a second guide rod 16 and a second mating portion that cooperate with each other. The second guide rod 16 is opposite the central axis of the feed member 12. The first guide rod 15 and the second guide rod 16 are spaced apart, and the reset member 13 is sleeved outside the second guide rod 16. When the second guide rod 16 moves relative to the second mating portion, it can compress or release the reset member 13. In this way, on the one hand, the linear bearing 14, the first guide rod 15 and the first mating portion, and the second guide rod 16 and the second mating portion ensure that the feed member 12 does not deviate when moving relative to the material holder 11 in the first direction; on the other hand, the second guide rod 16 also serves as a limit reset member 13.

[0079] Furthermore, a first stopper 161 is provided on the second guide rod 16, and a second stopper 111 is provided on the material holder 11. The second guide rod 16 passes through the second stopper 111 and is connected to the feed member 12. The reset member 13 is located between the second stopper 111 and the feed member 12 in the first direction. When the wiper 22 pushes the feed member 12, the reset member 13 is compressed between the feed member 12 and the second stopper 111. When the wiper 22 releases the feed member 12, the feed member 12 is reset by the reset member 13, and the first stopper 161 abuts the second stopper 111, thereby preventing the feed member 12 from separating from the material holder 11.

[0080] In some embodiments, the wiper 22 is movably coupled to the mounting seat 21 along a first direction, and the clamping member 23 is hingedly coupled to the mounting seat 21 and connected to the wiper 22. When the wiper 22 is controlled to move relative to the mounting seat 21 in the first direction to push the feed member 12, the wiper 22 can drive the clamping member 23 to rotate relative to the mounting seat 21. The clamping member 23 can cooperate with the wiper 22 to clamp the cleaning medium 2000. When the wiper 22 is controlled to return relative to the mounting seat 21, the clamping member 23 can release the cleaning medium 2000. That is, when the wiper 22 moves relative to the mounting seat 21 in the first direction, the clamping member 23 rotates relative to the mounting seat 21 to clamp or release the cleaning medium 2000.

[0081] Of course, in other embodiments, the wiping member 22 and the clamping member 23 do not move simultaneously relative to the mounting base 21. For example, it can be arranged that when the wiping member 22 pushes the cleaning medium 2000 so that the cleaning medium 2000 completely wraps the wiping member 22, the clamping member 23 moves again and cooperates with the wiping member 22 to clamp the cleaning medium 2000.

[0082] In one embodiment, the clamping member 23 abuts the wiping member 22, and the wiping mechanism 20 further includes an elastic member for resetting the clamping member 23. Thus, when the wiping member 22 moves relative to the mounting seat 21 in a first direction to push the cleaning medium 2000, the clamping member 23 rotates relative to the mounting seat 21 under the action of the wiping member 22 to clamp the cleaning medium 2000. When the wiping member 22 is reset, the clamping member 23 is reset under the action of the elastic member. In other embodiments, the clamping member 23 is hingedly connected to the wiping member 22. Thus, when the wiping member 22 moves relative to the mounting seat 21 in a first direction to push the cleaning medium 2000, the clamping member 23 rotates relative to the mounting seat 21 under the action of the wiping member 22 to clamp the cleaning medium 2000. When the wiping member 22 is reset, the clamping member 23 rotates relative to the mounting seat 21 to reset, driven by the wiping member 22.

[0083] In some embodiments, referring again to FIG. 14 , the wiping mechanism 20 further includes a first drive member 24 mounted on the mounting base 21 and connected to the wiping member 22. The first drive member 24 is capable of driving the wiping member 22 to reciprocate in a first direction. Specifically, the wiping member 22 includes a push-pull rod 221 and a wiping head 222. The wiping head 222 is connected to one end of the push-pull rod 221 in the first direction for clamping the feed member 12. The first drive member 24 is connected to the other end of the push-pull rod 221 in the first direction. The clamping member 23 includes a clamping jaw 232 and a connecting rod assembly 231 that are interconnected. The connecting rod assembly 231 is hingedly connected to the mounting base 21 and the push-pull rod 221. The clamping jaw 232 is used to clamp the cleaning medium 2000. The connecting rod assembly 231 includes a first connecting rod 2311 and a second connecting rod 2312 that are hinged to each other. The first connecting rod 2311 is hinged to the mounting base 21, and the middle portion of the second connecting rod 2312 is hinged to the push-pull rod 221. Thus, when the first driving member 24 pushes the push-pull rod 221 in a first direction, the push-pull rod 221 drives the wiping head 222 to move relative to the mounting base 21, pushing the wiping head 222 against the feed member 12. Specifically, when the cleaning medium 2000 is in sheet form, the wiping head 222 pushes the feed member 12 through the cleaning medium 2000. Simultaneously, the connecting rod assembly 231 rotates relative to the mounting base 21 and the push-pull rod 221, driving the clamping jaws 232 to rotate. When the cleaning medium 2000 wraps around the wiping head 222, the clamping jaws 232 clamp onto the side of the cleaning medium 2000 facing away from the wiping head 222, cooperating with the wiping head 222 to securely clamp the cleaning medium 2000. After the cleaning medium 2000 wipes the electrolyte, the first driving member 24 pulls the push-pull rod 221 along the first direction, and the push-pull rod 221 drives the wiping head 222 to move along the first direction relative to the mounting seat 21 and reset. At the same time, the connecting rod assembly 231 rotates relative to the mounting seat 21 and the push-pull rod 221 to drive the clamping jaw 232 to rotate and loosen the cleaning medium 2000. The cleaning medium 2000 is separated from the wiping head 222 under the action of gravity, and the clamping jaw 232 is reset.

[0084] In some embodiments, the first driving member 24 is a cylinder. It is conceivable that in other embodiments, the first driving member 24 can also be a motor or the like.

[0085] Furthermore, the wiping mechanism 20 includes at least two clamping members 23, all of which are spaced apart around an axis extending along the first direction and cooperate with the wiping member 22 to clamp the cleaning medium 2000. Thus, when the first driving member 24 pushes the push-pull rod 221 to drive the wiping head 222 to push the cleaning medium 2000, all of the clamping members 23 rotate and close under the drive of the push-pull rod 221 to synchronously clamp the cleaning medium 2000. Under the clamping action of the multiple clamping members 23, the clamping effect of clamping the cleaning medium 2000 is guaranteed, preventing the cleaning medium 2000 from falling during the wiping of the electrolyte. It should be noted that when the first driving member 24 pulls the push-pull rod 221 to drive the wiping head 222 to reset, all of the clamping members 23 rotate and open under the drive of the push-pull rod 221 to release the cleaning medium 2000.

[0086] In one specific embodiment, the wiping mechanism 20 includes two clamping members 23, which are positioned opposite each other on either side of the wiping member 22. When clamping the cleaning medium 2000, the two clamping members 23 can clamp the cleaning medium 2000 from opposite sides, ensuring a good clamping effect. In some embodiments, when the wiping member 22 or the push-pull rod 221 is cylindrical, the two clamping members 23 are radially located on either side of the wiping member 22.

[0087] Continuing with reference to Figures 6, 9, and 10, the wiping device 200 further includes a guide mechanism, which includes a guide groove 31 and a guide block 32. One of the guide block 32 and the guide groove 31 is located on the material holder 11, and the other is located on the clamping member 23, specifically, on the clamping claw 232 of the clamping member 23. When the clamping member 23 rotates relative to the mounting base 21 to clamp the cleaning medium 2000, the guide block 32 is inserted into the guide groove 31 to guide the clamping member 23 to prevent the clamping member 23 from deviating. In one embodiment, the guide block 32 is located on the material holder 11, in which case the pressure-applying portion is formed on the guide block 32, and the guide groove 31 is located on the clamping claw 232. In this case, the shape of the clamping claw 232 can be set to an inverted "U" shape. In another embodiment, the guide groove 31 is located on the material holder 11, and the guide block 32 is located on the clamping claw 232.

[0088] Continuing with Figure 13 , the wiping device 200 further includes a first sensor 40, which is disposed on the mounting base 21 and is used to detect whether the guide groove 31 and the guide block 32 are aligned. For example, the first sensor 40 can be a slot-type photoelectric sensor. Furthermore, the wiping device 200 further includes a second sensor 50, which is disposed on the mounting base 21 and is used to detect whether the wiping head 222 has successfully removed the material. For example, the second sensor 50 can be a laser sensor.

[0089] In some embodiments, the wiping mechanism 20 further includes a second driving member 25 connected to the mounting base 21. The second driving member 25 can drive the mounting base 21 to rotate the wiping member 22 and the clamping member 23 along an axis extending in the first direction. The second driving member 25 can rotate the clamping member 23 and the wiping member 22, thereby driving the cleaning medium 2000 to rotate and wipe the electrolyte.

[0090] It should be noted here that when the second driving member 25 drives the mounting seat 21 to drive the clamping member 23 and the wiping member 22 to rotate, the first driving member 24 will not rotate with the wiping member 22, that is, the first driving member 24 can drive the wiping member 22 to move along the first direction relative to the mounting seat 21, but will not limit its rotation.

[0091] Optionally, referring again to Figures 13 and 14, the wiping mechanism 20 further includes a transmission assembly 26, through which the second drive member 25 is connected to the mounting base 21. In some embodiments, the second drive member 25 is a motor, and the transmission assembly 26 includes a conveyor belt 261 and two pulleys 262. The two pulleys 262 are mounted on the second drive member 25 and the mounting base 21, respectively, and the conveyor belt 261 is sleeved around the two pulleys 262. It is contemplated that in other embodiments, the wiping mechanism 20 may omit the transmission assembly 26. When the wiping mechanism 20 is provided with the transmission assembly 26, the arrangement of the second drive member 25 and the transmission assembly 26 is not limited.

[0092] It should be noted that, in order to facilitate the installation of the pulley 262, the mounting seat 21 is a cylindrical structure, and the wiper 22 is disposed along the first direction through the mounting seat 21. Of course, in other embodiments, the shape of the mounting seat 21 is not limited.

[0093] Optionally, the wiping device 200 further includes a mounting frame 60, on which the first driving member 24, the second driving member 25, and the mounting base 21 are all mounted, thereby increasing the integration of the wiping device 200. To facilitate rotation of the mounting base 21 and the push-pull rod 221 relative to the mounting frame 60, a first bearing 70 is provided between the mounting base 21 and the mounting frame 60, and a second bearing 80 is provided between the push-pull rod 221 and the mounting frame 60.

[0094] Continuing to refer to FIG1 , the wiping system 1000 further includes a driving device 300, and at least one of the wiping mechanism 20 and the feeding mechanism 10 is connected to the driving device 300. The driving device 300 is used to drive the wiping mechanism 20 and the feeding mechanism 10 to generate relative motion in the first direction, the second direction, and the third direction, thereby adjusting the position between the wiping mechanism 20 and the feeding mechanism 10. The first direction, the second direction, and the third direction intersect with each other. Specifically, the first direction, the second direction, and the third direction are perpendicular to each other. Referring to FIG1-FIG3 , the first direction is the Z direction in FIG1 and FIG3 , the second direction is the X direction in FIG1 and FIG2 , and the third direction is the Y direction in FIG2 and FIG3 .

[0095] In some embodiments, the first drive device 300 includes a first drive mechanism 301 and a second drive mechanism 302. The wiping mechanism 20 is connected to the first drive mechanism 301, and the feeding mechanism 10 is connected to the second drive mechanism 302. The first drive mechanism 301 is used to drive the wiping mechanism 20 to move in the first direction and the second direction, and the second drive mechanism 302 is used to drive the feeding mechanism 10 to move in the second direction and the third direction, so as to adjust the positions of the wiping mechanism 20 and the feeding mechanism 10 in the first direction, the second direction, and the third direction, thereby facilitating the wiping mechanism 20 to pick up materials from the feeding mechanism 10.

[0096] Optionally, the first drive mechanism 301 includes a first drive module 3011 and a second drive module 3012. The second drive module 3012 is disposed on the first drive module 3011. The wiping mechanism 20 is connected to the second drive module 3012. The first drive module 3011 can drive the wiping mechanism 20 to move in the second direction via the second drive module 3012. The first drive module 3011 is used to drive the wiping mechanism 20 to move in the first direction. Referring to Figures 15-17, the second drive mechanism 302 includes a first drive assembly 3021 and a second drive assembly 3022. The first drive assembly 3021 is used to drive the feeding mechanism 10 to move in the second direction, and the second drive assembly 3022 is used to drive the feeding mechanism 10 to move in the third direction.

[0097] When the wiping system 1000 includes multiple wiping devices 200, the wiping mechanisms 20 of the multiple wiping devices 200 can all move synchronously along the first and second directions, and the feeding mechanisms 10 of the multiple wiping devices 200 can all move synchronously along the second and third directions. In some specific embodiments, the wiping system 1000 includes four wiping devices 200. Of course, in other embodiments, the number of wiping devices 200 included in the wiping system 1000 is not limited.

[0098] Continuing with Figure 1 , the wiping system 1000 also includes a cutting device 400, which is used to cut the cleaning tape into cleaning media 2000 to facilitate wiping the dissolved electrolyte. The feed mechanism 10 is capable of carrying the cleaning media 2000 cut by the cutting device 400 and, under the action of the aforementioned drive device 300, is positioned to face the wiping mechanism 20. The wiping member 22 of the wiping mechanism 20 is capable of pushing the cleaning media 2000 from the feed mechanism 10 and cooperating with the clamping member 23 to remove the cleaning media.

[0099] Referring to Figure 18 , the cutting device 400 includes a first cutter 401, a second cutter 402, a pressure block 403, and a cutting drive 404. The pressure block 403 and the second cutter 402 are both connected to the cutting drive 404, which is used to drive the pressure block 403 and the second cutter 402 toward or away from the first cutter 401. When the cutting drive 404 drives the pressure block 403 and the second cutter 402 toward the first cutter 401, the pressure block 403 cooperates with the feeding mechanism 10 to compress the cleaning tape, and the second cutter 402 cooperates with the first cutter 401 to cut the cleaning tape to form the cleaning medium 2000. Specifically, the cutting drive 404 is a cylinder. Of course, the cutting drive 404 can also be a motor, etc.

[0100] With the above arrangement, when the cleaning tape is conveyed to the cutting device 400, the cutting drive 404 drives the pressing block 403 and the second cutter 402 to move close to the first cutter 401. When the second cutter 402 cooperates with the first cutter 401 to cut the cleaning tape, the pressing block 403 cooperates with the feeding mechanism 10 to press the cleaning tape to cut the cleaning tape into the cleaning medium 2000, thereby ensuring the cutting effect.

[0101] In some embodiments, referring to Figure 1 , the wiping system 1000 further includes a material preparation device 500 for conveying the cleaning tape to the cutting device 400 for cutting by the cutting device 400. Specifically, the material preparation device 500 can tighten the cleaning tape unwound by the unwinding reel 700 and convey it to the cutting device 400 for cutting.

[0102] Referring to Figure 19 , the material preparation device 500 includes a driving roller 501, a pinch roller 502, a third drive member 503, and a fourth drive member 504. The driving roller 501 is connected to the third drive member 503, while the pinch roller 502 is connected to the fourth drive member 504. A feed gap is formed between the pinch roller 502 and the driving roller 501 for conveying the cleaning tape. The third drive member 503 drives the driving roller 501 to rotate, feeding the cleaning tape to the cutting device 400. The fourth drive member 504 drives the pinch roller 502 toward or away from the driving roller 501 to change the width of the feed gap. Thus, when the conveyor tape 261 unwound from the unwinding reel 700 enters the feed gap, the third drive member 503 drives the driving roller 501 to rotate, and the pinch roller 502 and the driving roller 501 cooperate to feed the cleaning tape to the cutting device 400. The fourth drive member 504 allows the width of the feed gap to be varied to accommodate cleaning tapes of varying thicknesses, facilitating compaction of the cleaning tape.

[0103] Furthermore, the material preparation device 500 also includes a pressure reducing valve 505 and a manual reversing valve 506. The pressure reducing valve 505 can adjust the thrust of the fourth driving member 504, thereby adjusting the pressure of the pressure wheel 502. The manual reversing valve 506 is used to lift the pressure wheel 502 when replacing the cleaning belt.

[0104] Continuing with Figure 1 , the wiping system 1000 further includes a waste collection device 600 to collect the cleaning sheet after the wiping mechanism 20 wipes the battery. Specifically, when the second drive module 3012 drives the wiping mechanism 20 in the first direction to the waste collection device 600, the wiping mechanism 20 releases the cleaning medium 2000, which falls into the waste collection device 600 under the action of gravity.

[0105] Referring to FIG. 20 , the waste collection device 600 includes a waste box 601 and a brush 602. The waste box 601 has an opening, and the brush 602 is disposed within the opening. The second drive module 3012 is capable of driving the wiping mechanism 20 to move in a first direction, causing the wiping head 222 to pass through the brush 602 and enter the waste box 601. Thus, when the wiping mechanism 20 releases the cleaning medium 2000, the cleaning medium 2000 falls into the waste box 601 under the action of gravity. Simultaneously, when the wiping head 222 passes through the brush 602 and is pulled out of the waste box 601, friction is generated between the brush 602 and the wiping head 222. This frictional force causes any cleaning medium 2000 that has not been released from the wiping head 222 by gravity to remain in the waste box 601, preventing used cleaning medium 2000 from adhering to the wiping head 222 and affecting the subsequent wiping effect.

[0106] Another embodiment of the present disclosure further provides a wiping device 200 included in the wiping system 1000. The wiping device 200 includes a feeding mechanism 10 and a wiping mechanism 20. The feeding mechanism 10 includes a material holder 11 and a feeding member 12. The feeding member 12 is movably mounted on the material holder 11 along a first direction and is used to hold a cleaning medium 2000. The wiping mechanism 20 includes a mounting seat 21, a wiping member 22, and a clamping member 23. Both the wiping member 22 and the clamping member 23 are mounted on the mounting seat 21. The wiping member 22 is controllably movable in the first direction and pushes the feeding member 12. Under the push of the wiping member 22, the feeding member 12 moves relative to the material holder 11 along the first direction.

[0107] The above-mentioned wiping device 200, the clamping part 23 of the wiping mechanism 20 cooperates with the wiping part 22 to clamp the cleaning medium 2000. Compared with the method of using vacuum adsorption to adsorb the cleaning medium 2000 onto the wiping mechanism 20 in the related art, there is no need to set a vacuum air path on the wiping mechanism 20, so there is no problem of air path blockage. The wiping mechanism 20 is easy to maintain, which saves maintenance time and thus improves production efficiency.

[0108] Using the wiping device 200 and the wiping system 1000 provided by the present disclosure, the wiping process for wiping the electrolyte at the battery filling port is as follows:

[0109] When the battery is transported to the bottom of the injection device 100 via the pull belt, the injection needle 103 of the injection device 100 injects the dissolving liquid into the injection port of the battery to dissolve the electrolyte crystallized at the injection port.

[0110] The material preparation device 500 feeds the cleaning tape to the cutting device 400. The second drive mechanism 302 is activated to position the feed mechanism 10 relative to the pressure block 403 of the cutting device 400. The pressure block 403 of the cutting device 400 presses the cleaning tape against the feed mechanism 10. The second cutter 402 cooperates with the first cutter 401 to cut the cleaning tape into cleaning media 2000. The feed member 12 of the feed mechanism 10 absorbs the cleaning media 2000 through the vacuum suction holes. The drive mechanism 300 causes the feed mechanism 10 to face the wiping mechanism 20 in the first direction. At this time, the cleaning media 2000 is opposite the wiping mechanism 20.

[0111] Referring to Figures 21 and 22, the first driving member 24 of the wiping mechanism 20 pushes the push-pull rod 221, driving the wiping head 222 to move in a first direction toward the feeding mechanism 10, causing the wiping head 222 to contact the cleaning medium 2000. Referring to Figures 23 and 24, the wiping head 222 continues to move and pushes the cleaning medium 2000. Under the action of the pressure-applying portion, the cleaning medium 2000 flips over and wraps around the wiping head 222. Specifically, in the initial position, the feeding member 12 is flush with the end surface of the guide block 32. When the end surface of the feeding member 12 is 10 mm lower than the end surface of the guide block 32, the cleaning medium 2000 forms a "U" shape and wraps around the wiping head 222. Each clamping member 23 closes, clamping the cleaning medium 2000. 25 and 26 , the second driving module 3012 drives the wiping mechanism 20 to move a certain distance in the opposite direction in the first direction, so that the wiping head 222 is separated from the feeding member 12 , for example, by moving 20 mm.

[0112] The driving device 300 drives the wiping mechanism 20 to move to face the battery, and the second driving member 25 drives the mounting seat 21 to drive the wiping member 22 and the clamping member 23 to rotate, driving the cleaning medium 2000 to rotate and wipe the liquid filling port of the battery.

[0113] The drive device 300 moves the wiping mechanism 20, positioning the used cleaning medium 2000 toward the waste collection device 600. The first drive member 24 pulls the push-pull rod 221, which opens the clamping member 23, releasing the cleaning medium 2000, which is then dropped into the waste collection device 600. The drive device 300 then resets the wiping mechanism 20 to pick up the next piece of cleaning medium 2000 and begin the next battery wiping cycle.

[0114] It should be noted that some steps in the above process can be performed sequentially or simultaneously, and are not specifically limited here.

[0115] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0116] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
