[0058] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0060] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0061] At present, during the battery production process, electrolyte needs to be quantitatively injected into the battery, and after the injection, residual electrolyte will still remain around the battery injection port. If the residual electrolyte is not cleaned, the residual electrolyte will not only corrode the battery shell, but also the residual electrolyte crystallization will cause welding explosion points when the battery is sealed.

[0062] The existing method for cleaning the liquid injection port of the battery is to use a reeled non-woven fabric to manually wipe the liquid injection port in a dry manner, that is, to manually wipe the electrolyte remaining at the liquid injection port clean with a dry non-woven fabric. However, the cleaning efficiency of manual cleaning is not high, and the wiping effect of the non-woven fabric dry wiping method is not good.

[0063] In order to solve the technical problems of low cleaning efficiency and poor cleaning effect faced by the existing cleaning method of the electrolyte at the battery filling port, Figures 1 to 3An embodiment of the utility model provides a liquid injection port cleaning device, which can be used to wipe and clean the electrolyte remaining at the liquid injection port of a cylindrical battery. The cleaning device includes a frame 100, a reeling mechanism 200, a transmission mechanism 300, a liquid injection mechanism 400 and a wiping mechanism 500. Among them, the frame 100 provides a mounting carrier for the reeling mechanism 200, the transmission mechanism 300, the liquid injection mechanism 400 and the wiping mechanism 500, and the reeling mechanism 200, the transmission mechanism 300, the liquid injection mechanism 400 and the wiping mechanism 500 are all arranged on the frame 100, thereby improving the integration level of the liquid injection port cleaning device and reducing the overall space occupied by the liquid injection port cleaning device.

[0064] The unwinding mechanism 200 is wound with a wiping tape 1700, which is used to unwind the wiping tape 1700 and provide a material basis for the subsequent use of the wiping tape 1700 to clean the liquid injection port. In order to facilitate the unwinding of the wiping tape 1700, the unwinding mechanism 200 can be designed as a disc-shaped structure. For example, the unwinding mechanism 200 can be a turntable, and the wiping tape 1700 is wound on the circumferential side wall of the turntable. Further, the circumferential side wall of the turntable can be circumferentially provided with a circle of grooves to facilitate winding and accommodating more turns of the wiping tape 1700. The unwinding mechanism 200 is rotatably connected to the frame 100 through a rotating shaft, so that the wiping tape 1700 can be unwound layer by layer, thereby improving the smoothness of the unwinding of the wiping tape 1700.

[0065] In some embodiments, the wiping tape 1700 may be a non-woven fabric.

[0066] The transmission mechanism 300 is connected to the wiping belt 1700 and is used to transmit the wiping belt 1700. The wiping belt 1700 can be transmitted to the wiping area through the transmission mechanism 300 to complete the wiping and cleaning of the battery filling port. The transmission mechanism 300 can provide effective support for the wiping belt 1700 to prevent the wiping belt 1700 from loosening during the transmission process and ensure that the wiping belt 1700 is in a taut state. In some embodiments, the transmission mechanism 300 can be a roller structure or a wheel structure.

[0067] The injection mechanism 400 includes a liquid storage tank 410, a liquid injection pump and a liquid injection part 420. The liquid injection pump is used to pump the cleaning liquid in the liquid storage tank 410 to the liquid injection part 420, and spray the cleaning agent on the wiping belt 1700 through the liquid injection part 420. The liquid storage tank 410 and the liquid injection part 420 can be connected through a conduit. The liquid injection pump is equivalent to a control valve of the cleaning liquid. When the liquid injection pump is started, the cleaning liquid can be pumped from the liquid storage tank 410 along the conduit to the liquid injection part 420 to be sprayed, thereby wetting the wiping belt 1700. When the liquid injection pump is turned off, the cleaning liquid will not be pumped to the liquid injection part 420, thereby keeping the wiping belt 1700 dry. In some embodiments, the cleaning liquid can be a carbonate solvent to quickly dissolve the electrolyte at the battery injection port to improve the wiping effect of the wiping belt 1700.

[0068] Along the transmission direction of the wiping belt 1700, the wiping mechanism 500 is located on the downstream side of the injection mechanism 400. The wiping mechanism 500 includes a first motor 510 and a wiping head 520. The wiping head 520 is connected to the driving shaft of the first motor 510. The first motor 510 drives the wiping head 520 to move toward or away from the wiping belt 1700 and drives the wiping head 520 to rotate.

[0069] In short, in the technical solution of this embodiment, the liquid injection port cleaning device includes a frame 100, and the frame 100 is provided with an unwinding mechanism 200, a transmission mechanism 300, a liquid injection mechanism 400 and a wiping mechanism 500. The unwinding mechanism 200 is wound with a wiping belt 1700 for unwinding the wiping belt 1700. The wiping belt 1700 is wound and connected to the transmission mechanism 300, and the wiping belt 1700 is transmitted from the upstream side to the downstream side through the transmission mechanism 300. Along the transmission direction of the wiping belt 1700, the injection mechanism 400 is arranged on the downstream side of the unwinding mechanism 200, and the injection mechanism 400 includes a liquid storage tank 410, a liquid injection pump and a liquid injection part 420. When the liquid injection pump is turned on, the cleaning liquid in the liquid storage tank 410 can be pumped to the liquid injection part 420, which is used to spray liquid on the wiping belt 1700 conveyed to the liquid injection part 420, so that the wiping belt 1700 is moistened, thereby facilitating subsequent wet wiping. When the liquid injection pump is turned off, the wiping belt 1700 conveyed to the liquid injection part 420 can be stopped from being sprayed with liquid, so that the wiping belt 1700 remains dry, thereby facilitating subsequent dry wiping. Along the transmission direction of the wiping belt 1700, the wiping mechanism 500 is arranged on the downstream side of the injection mechanism 400, and the wiping mechanism 500 includes a first motor 510 and a wiping head 520. The wiping head 520 is connected to the driving shaft of the first motor 510, and the first motor 510 drives the wiping head 520 to move toward or away from the wiping belt 1700 and drives the wiping head 520 to rotate.

[0070] When using the cleaning device to wipe the liquid injection port of the battery, the battery is loaded onto the wiping mechanism 500 so that the liquid injection port and the wiping head 520 are opposite to each other, and the wiping belt 1700 passes between the liquid injection port and the wiping head 520. During the wiping process, the liquid injection port is first wet-wiped to facilitate dissolving the electrolyte at the liquid injection port. When wet-wiping, the wiping belt 1700 is wetted with cleaning liquid in advance, and the wiping head 520 moves in a direction close to the wiping belt 1700 and presses the wiping belt 1700 against the liquid injection port. At the same time, the wiping head 520 rotates forward and reversely to drive the wiping belt 1700 to twist back and forth, thereby achieving wet wiping of the wiping belt 1700. After wet wiping is completed, the liquid injection port is dry-wiped to keep the liquid injection port dry. When dry wiping, there is no need to pre-wet the wiping belt 1700. Use the wiping head 520 to press the wiping belt 1700 on the liquid injection port and drive the wiping belt 1700 to twist back and forth, thereby achieving dry wiping of the wiping belt 1700.

[0071] The liquid filling port cleaning device provided in this embodiment can rely on the cooperation between the unwinding mechanism 200, the transmission mechanism 300, the liquid filling mechanism 400 and the wiping mechanism 500 to automatically wipe and clean the battery liquid filling port, which can improve production efficiency and save labor costs. In addition, the cleaning device can achieve wet wiping first and then dry wiping, which is beneficial to improving the wiping effect.

[0072] In some embodiments, reference Figure 1 to Figure 2 , a main structure of a transmission mechanism 300 is provided, for example, the transmission mechanism 300 includes an active roller 310 and a first transmission roller 320, along the transmission direction of the wiping belt 1700, the active roller 310 is arranged on the downstream side of the wiping mechanism 500, and the first transmission roller 320 is arranged between the unwinding mechanism 200 and the active roller 310.

[0073] Specifically, the active roller 310 provides power for pulling the wiping belt 1700, and is the power source for pulling the wiping belt 1700 to move. The first transmission roller 320 provides effective support during the transmission process of the wiping belt 1700, and there is no additional power on the first transmission roller 320, that is, the first transmission roller 320 is fixed on the frame 100 and cannot rotate. This can prevent the first transmission roller 320 from sliding and causing the wiping belt 1700 to loosen, thereby ensuring that the wiping belt 1700 is in a taut state in the entire device.

[0074] In this embodiment, refer to Figure 1 to Figure 2 The transmission mechanism 300 includes an active roller 310 and a plurality of first transmission rollers 320. Along the transmission direction of the wiping belt 1700, the active roller 310 is arranged at the downstream side of the wiping mechanism 500. The plurality of first transmission rollers 320 are arranged between the unwinding mechanism 200 and the active roller 310 according to the actual processing requirements and the routing mode of the wiping belt 1700. When the cleaning device is in working state, the active roller 310 rotates. Under the pulling action of the active roller 310, the wiping belt 1700 is unwound by the unwinding mechanism 200 and is transmitted to the injection mechanism 400 along the layout path of the first transmission roller 320. At the injection mechanism 400, it can be selected whether to wet the wiping belt 1700, and then it is transmitted to the wiping mechanism 500 along the layout path of the first transmission roller 320. At the wiping mechanism 500, wiping and cleaning at the battery injection port is realized.

[0075] The transmission mechanism 300 provided in this embodiment is simple and orderly, and only one active roller 310 is provided for pulling the wiping belt 1700 to move. Compared with providing multiple active rollers 310, it can avoid the inconsistent pulling force on the wiping belt 1700 at different positions due to the synchronization error between the multiple active rollers 310, thereby ensuring that the wiping belt 1700 will not loosen during the transmission process.

[0076] In some embodiments, the active roller 310 may be replaced by a rotatable active wheel, and the first transmission roller 320 may be replaced by a fixed transmission wheel.

[0077] In some embodiments, reference Figure 4 A cloth pressing mechanism 700 is provided at the active roller 310, and the cloth pressing mechanism 700 includes a first cylinder 710 and a roller 720. The roller 720 is connected to the piston rod of the first cylinder 710. The rolling surface of the roller 720 and the rolling surface of the active roller 310 are arranged in close contact with each other, so as to form rolling pressure on the wiping belt 1700 passing between the roller 720 and the active roller 310.

[0078] Specifically, in order to further ensure that the wiping belt 1700 does not loosen during the conveying process, a cloth pressing mechanism 700 is provided at the active roller 310 to roll and press the wiping belt 1700 passing through the active roller 310 to prevent the wiping belt 1700 on the active roller 310 from slipping when the active roller 310 rotates, thereby ensuring that the wiping belt 1700 is tensioned at the active roller 310. The roller 720 of the cloth pressing mechanism 700 can be fixedly arranged so that it does not rotate with the active roller 310. When the active roller 310 rotates, the roller 720 can provide a pressing force for the wiping belt 1700 to maintain the tensioned state of the wiping belt 1700. The distance between the roller 720 and the active roller 310 can be adjusted by extending and retracting the piston rod of the first cylinder 710. Specifically, the distance between the roller 720 and the active roller 310 can be adjusted according to the passing state of the wiping belt 1700, so as to ensure the pressing force of the roller 720 on the wiping belt 1700 while the wiping belt 1700 passes through. In some embodiments, the roller 720 can be a rubber wheel to increase the friction between the roller 720 and the wiping belt 1700, and effectively prevent the roller 720 and the wiping belt 1700 from slipping.

[0079] Preferably, in order to further ensure that the wiping belt 1700 does not become loose during the conveying process, a cloth pressing mechanism 700 may be provided at the first transmission roller 320 based on a structure similar to the above-mentioned embodiment. For example, the cloth pressing mechanism 700 may be provided at intervals between several first transmission rollers 320, or may be provided at a position where the wiping belt 1700 is prone to slip. The structural design and working method of the cloth pressing mechanism 700 may refer to the above-mentioned embodiment and will not be described in detail here.

[0080] In some embodiments, reference Figure 1 to Figure 2In order to ensure that the wiping belt 1700 can be transmitted in an orderly manner, as described in the above embodiment, the transmission mechanism 300 includes a plurality of first transmission rollers 320, and a first counterweight block 800 is arranged between the first transmission rollers 320. The first counterweight block 800 is provided with a first transition roller 810. Along the transmission direction of the wiping belt 1700, the wiping belt 1700 passes by the first transmission roller 320 on the upstream side, bypasses the first transition roller 810, and is connected to the first transmission roller 320 on the downstream side, so that the first counterweight block 800 drives the wiping belt 1700 to move or the wiping belt 1700 drives the first counterweight block 800 to move.

[0081] Specifically, since the wiping belt 1700 is a whole continuous belt structure, and the transmission path of the wiping belt 1700 on the device is relatively complicated, if the wiping belt 1700 slips or loosens at any position, it will seriously affect the normal progress of the subsequent processes. Therefore, this embodiment designs a "transfer station" for the wiping belt 1700 (the "transfer station" here refers to the first counterweight block 800 in this embodiment), and divides the large path formed from the unwinding mechanism 200 to the wiping mechanism 500 into two small paths formed from the unwinding mechanism 200 to the first counterweight block 800 and from the first counterweight block 800 to the wiping mechanism 500. In other words, driven by the rotation of the active roller 310, the wiping belt 1700 will be transmitted from the unwinding mechanism 200 to the first counterweight block 800, and then transmitted from the first counterweight block 800 to the injection mechanism 400 and the wiping mechanism 500. Since the wiping belt 1700 is wound around the first transition roller 810, the first counterweight block 800 can drive the wiping belt 1700 to move, or the wiping belt 1700 can drive the first counterweight block 800 to move, so the wiping belt 1700 will accumulate or discharge at the first counterweight block 800.

[0082] Among them, refer to Figure 1 to Figure 2 A first slide rail 900 is provided on the frame 100, and a first slider 820 is provided on the first counterweight block 800. The first counterweight block 800 is slidably connected to the first slide rail 900 through the first slider 820. Along the sliding direction of the first counterweight block 800, a first position sensor 1000 is provided at one end of the first slide rail 900 for detecting that the first counterweight block 800 is located at the first position, and the controller controls the unwinding mechanism 200 to discharge the wiping tape 1700. A second position sensor 1100 is provided at the other end of the first slide rail 900 for detecting that the first counterweight block 800 is located at the second position, and the controller controls the unwinding mechanism 200 to stop discharging the wiping tape 1700.

[0083] Specifically, assuming that the first slide rail 900 is vertically arranged on the rack 100, the upper end of the first slide rail 900 is the first position, and a first position sensor 1000 is arranged at the first position, and the lower end of the first slide rail 900 is the second position, and a second position sensor 1100 is arranged at the second position. At first, when the first counterweight block 800 is located at the first position, the first position sensor 1000 will be triggered, and the first position sensor 1000 will transmit a signal to the controller. After reading the signal, the controller will control the unwinding mechanism 200 to discharge the wiping tape 1700, and the active roller 310 will drive the wiping tape 1700 to move. As the amount of wiping tape 1700 between the unwinding mechanism 200 and the active roller 310 increases, and due to the gravity of the first counterweight block 800, the first counterweight block 800 will drive the wiping tape 1700 to move downward along the first slide rail 900. When the first counterweight block 800 moves to the second position, the second position sensor 1100 will be triggered, and the second position sensor 1100 will transmit a signal to the controller. After reading the signal, the controller will control the unwinding mechanism 200 to stop discharging the wiping tape 1700. At this time, a certain amount of wiping tape 1700 will accumulate at the first counterweight block 800, and the wiping tape 1700 will be pressed tightly by the first transition roller 810. As the active roller 310 continuously drives the wiping belt 1700 to move, the wiping belt 1700 will drive the first counterweight block 800 to gradually move upward along the first slide rail 900. When the first counterweight block 800 moves back to the first position, the first position sensor 1000 will be triggered again, and then the unwinding mechanism 200 will be controlled again to unwind the wiping belt 1700, and the above actions will be repeated to achieve intermittent unwinding of the unwinding mechanism 200.

[0084] By using the above-mentioned method of intermittently unloading the unwinding mechanism 200 through the first counterweight block 800, the overall long unloading path can be simplified, and the wiping belt 1700 can be conveyed in sections, thereby reducing the probability of the wiping belt 1700 being loose during the conveying process, and ensuring that the liquid filling port cleaning process can be carried out in an orderly manner. It can be understood that this is conducive to shortening the number of maintenance times and thus improving production efficiency.

[0085] In some embodiments, reference Figure 1 to Figure 2 The liquid injection port cleaning device also includes a winding mechanism 600, which is rotatably connected to the frame 100 and is located on the downstream side of the active roller 310 along the transmission direction of the wiping belt 1700, and is used to wind and reel the wiping belt 1700 after wiping.

[0086] Specifically, in order to facilitate the recycling of the wiping tape 1700 after wiping and avoid environmental pollution caused by littering of the wiping tape 1700, after the wiping tape 1700 wipes and cleans the battery filling port at the wiping mechanism 500, it will continue to be transported to the downstream side under the drive of the active roller 310, and finally complete the collection at the reeling mechanism 600. The wiping tape 1700 that is rolled up on the reeling mechanism 600 can be manually removed and recycled for secondary use. The setting of the reeling mechanism 600 improves the overall automation level of the cleaning device, realizes the integration of unwinding, wiping, and rewinding, reduces labor costs, and improves production efficiency.

[0087] In some embodiments, reference Figure 1 to Figure 2 , and referring to the unwinding mechanism 200 described in the above embodiment, the rewinding mechanism 600 may be a turntable structure, and is rotatably connected to the frame 100 via a rotating shaft. When rewinding, the wiping tape 1700 is wound around the circumferential side wall of the turntable. Furthermore, the circumferential side wall of the turntable may be provided with a circle of grooves in the circumferential direction, so as to facilitate the winding and accommodating of more turns of the wiping tape 1700, thereby extending the unloading cycle of the wiping tape 1700.

[0088] In some embodiments, reference Figure 1 to Figure 2 The transmission mechanism 300 also includes a second transmission roller 330. Along the transmission direction of the wiping belt 1700, a plurality of second transmission rollers 330 are arranged between the active roller 310 and the winding mechanism 600. A second counterweight 1200 is arranged between the second transmission rollers 330. The second counterweight 1200 is provided with a second transition roller 1210. Along the transmission direction of the wiping belt 1700, the wiping belt 1700 passes by the second transmission roller 330 on the upstream side, bypasses the second transition roller 1210, and is connected to the second transmission roller 330 on the downstream side, so that the second counterweight 1200 drives the wiping belt 1700 to move or the wiping belt 1700 drives the second counterweight 1200 to move.

[0089] Among them, refer to Figure 1 to Figure 2 A second slide rail 1300 is arranged on the frame 100, and a second slider 1220 is arranged on the second counterweight block 1200. The second counterweight block 1200 is slidably connected to the second slide rail 1300 through the second slider 1220. Along the sliding direction of the second counterweight block 1200, a third position sensor 1400 is arranged at one end of the second slide rail 1300 for detecting that the second counterweight block 1200 is located at the first position, and the controller controls the winding mechanism 600 to stop winding the wiping tape 1700. A fourth position sensor 1500 is arranged at the other end of the second slide rail 1300 for detecting that the second counterweight block 1200 is located at the second position, and the controller controls the winding mechanism 600 to wind the wiping tape 1700.

[0090] Specifically, after the wiping tape 1700 completes wiping and cleaning the battery filling port at the wiping mechanism 500, it will continue to be transported to the downstream side under the driving action of the active roller 310, and the wiping tape 1700 will be transported to the winding mechanism 600 by the second transmission roller 330 to complete the winding of the wiping tape 1700. Referring to the first counterweight block 800 described in the above embodiment, a second counterweight block 1200 is arranged between the second transmission rollers 330 to divide the large path formed from the active roller 310 to the winding mechanism 600 into two small paths formed from the active roller 310 to the second counterweight block 1200 and from the second counterweight block 1200 to the winding mechanism 600. In other words, in the process of conveying the wiping belt 1700 to the winding mechanism 600, the wiping belt 1700 will be conveyed by the active roller 310 to the second counterweight block 1200, and then conveyed to the winding mechanism 600 from the second counterweight block 1200. Since the wiping belt 1700 is wound around the second transition roller 1210, the second counterweight block 1200 can drive the wiping belt 1700 to move, or the wiping belt 1700 can drive the second counterweight block 1200 to move, so the wiping belt 1700 will be accumulated or discharged at the second counterweight block 1200.

[0091] Further, it is assumed that the second slide rail 1300 is vertically arranged on the frame 100, the upper end of the second slide rail 1300 is the first position, and the third position sensor 1400 is arranged at the first position, and the lower end of the second slide rail 1300 is the second position, and the fourth position sensor 1500 is arranged at the second position. Initially, when the second counterweight 1200 is located at the first position, the third position sensor 1400 will be triggered, and the third position sensor 1400 will transmit a signal to the controller. After reading the signal, the controller will control the winding mechanism 600 to stop the wiping tape 1700 from winding. As the active roller 310 continuously transmits the wiping tape 1700, more and more wiping tape 1700 is accumulated at the second counterweight 1200. Due to the gravity of the second counterweight 1200, the second counterweight 1200 will drive the wiping tape 1700 to move downward along the second slide rail 1300, and the wiping tape 1700 will be pressed by the second transition roller 1210. When the second counterweight block 1200 moves to the second position, the fourth position sensor 1500 will be triggered, and the fourth position sensor 1500 will transmit the signal to the controller. After reading the signal, the controller will control the winding mechanism 600 to wind up the wiping tape 1700. At this time, the accumulated wiping tape 1700 is gradually gathered, and drives the second counterweight block 1200 to gradually move upward along the second slide rail 1300. When the second counterweight block 1200 moves back to the first position, the third position sensor 1400 will be triggered again, and then the winding mechanism 600 will be controlled again to stop wiping the material to be wound up, and the above actions will be repeated to realize intermittent material collection of the winding mechanism 600.

[0092] By using the second counterweight block 1200 to realize the intermittent material collection of the reeling mechanism 600, the overall long material collection path can be simplified, and the wiping belt 1700 can be conveyed in sections, thereby reducing the probability of the wiping belt 1700 being loose during the conveying process, and ensuring that the material collection process can be carried out in an orderly manner. It can be understood that this is conducive to shortening the number of maintenance times and thus improving production efficiency.

[0093] Preferably, in some embodiments, in order to ensure that the wiping tape 1700 does not loosen during the winding process, thereby ensuring the winding effect of the wiping tape 1700, so that the wiping tape 1700 is finally rolled into a neat and compact roll, refer to Figure 1 to Figure 2 A cloth pressing mechanism 700 may be provided at the second transmission roller 330. For example, the cloth pressing mechanism 700 may be provided at intervals between several second transmission rollers 330, or the cloth pressing mechanism 700 may be provided at a position where the wiping belt 1700 is prone to slip. The structural design and working method of the cloth pressing mechanism 700 may refer to the above-mentioned embodiment and will not be described in detail here.

[0094] In some embodiments, dampers (not shown) are provided on the first transmission roller 320 and the second transmission roller 330. During the transmission of the wiping tape 1700, in order to prevent the wiping tape 1700 from loosening, no additional power is added to the first transmission roller 320 and the second transmission roller 330, and the dampers are provided to further prevent the first transmission roller 320 and the second transmission roller 330 from sliding, thereby avoiding slipping between the wiping tape 1700 and the first transmission roller 320 and between the wiping tape 1700 and the second transmission roller 330, and ensuring orderly transmission of the wiping tape 1700.

[0095] It should be noted that the damper is a commonly used component in the art, and its structure and installation method can be referred to in the prior art, so it will not be described in detail here.

[0096] In some embodiments, reference Figure 3 , the two opposite side walls of the rack 100 are provided with an unwinding mechanism 200, a transmission mechanism 300, a liquid injection mechanism 400, a wiping mechanism 500 and a winding mechanism 600. In the actual production process, the cleaning work of the battery liquid injection port can be carried out simultaneously on the two side walls of the rack 100, with the same work and no interference with each other, which is conducive to improving production efficiency, reducing time costs, and making full use of the rack 100, improving the utilization rate of the rack 100, and saving the space occupied by the device in the factory. For example, under the same space usage area, several more cleaning devices of the present invention can be installed, or when the cleaning device meets the production quantity requirements, space can be saved for installing other equipment.

[0097] In some embodiments, reference Figure 1 to Figure 2The liquid injection port cleaning device also includes a lifting mechanism 1600 for adjusting the overall height of the liquid injection port cleaning device. With such a structure, the height of the liquid injection port cleaning device can be adaptively adjusted according to the height of the battery feeding mechanism, so that the wiping head 520 can smoothly wipe and clean the battery liquid injection port. For example, the lifting mechanism 1600 can use a hydraulic cylinder to adjust the height of the cleaning device through the hydraulic cylinder to provide an applicable range of the cleaning device.

[0098] Correspondingly, another embodiment of the present invention further provides a production line, which includes the liquid injection port cleaning device in any of the above embodiments.

[0099] In this embodiment, specifically, the production line may be a cylindrical battery production line, and the production line may also include a battery loading mechanism, etc. Thanks to the improvement of the above-mentioned liquid injection port cleaning device, the production line of this embodiment has the same technical effect as the above-mentioned liquid injection port cleaning device, which will not be repeated here.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
