- the cleaning belt is a whole, and residual liquid of the previous battery is absorbed by the cleaning belt, and may flow to the rear cleaning belt, which causes the next battery to be polluted during wiping, and makes it easy for the battery to be cross-contaminated before and after wiping of a wiping belt.

- all-round wiping of a liquid injection port can be realized by designing a wiping head to be in a porous profiling shape, and a cleaning belt in the shape of an independent sheet.

- a clamp cylinder is used to clamp feeding material, which can prevent the cleaning belt from falling off.
- a finger cylinder clamps the cut cleaning belt and sends it to the corresponding position, then the hollow wiping structure descends, and the porous profiling wiping head rotates to carry out wiping while absorbing the residual liquid, which not only reduces cross-contamination of the electrolyte, but also improves the wiping effect.
- a rotary wiping structure is provided with a servo motor having a module movement on upper and lower sides, so that pressure and a wiping process of the cleaning belt are precise and controllable.

- At present, in the technical field of lithium battery manufacturing, wiping of a liquid injection port by a cleaning device cannot achieve the effect, and welding failure rate is high. This is because a contact area between a wiping head and the liquid injection port is small, and a cleaning belt is a pulling belt structure, and cannot carry out wiping in all directions. Rotary movement of the wiping head conflicts with the pulling structure of the cleaning belt, and the cleaning belt needs to be loosened for a certain length before wiping, so it is easy to fall off, failure rate is high, and troubleshooting time is long. Generally, the cleaning belt is a whole, and residual liquid of the previous battery is absorbed by the cleaning belt, and may flow to the rear cleaning belt, which causes the next battery to be polluted during wiping, and makes it easy for the battery to be cross-contaminated before and after wiping of a wiping belt. Since the cleaning belt is in a pulling structure, many tensioning structures are provided at both ends, and a cleaning belt located at the part of the tensioning structures does not participate in cleaning so that utilization rate of the cleaning belt is low.
- The applicant noticed that all-round wiping of a liquid injection port can be realized by designing a wiping head to be in a porous profiling shape, and a cleaning belt in the shape of an independent sheet. A hollow design of the entire rotating mechanism can absorb residual liquid and remove the cleaning belt through negative pressure, which can improve wiping effect. Moreover, a cutting structure is used in conjunction with the rotary wiping mechanism, which can realize rotary wiping at high speed while avoiding cross-contamination of a battery cell, and therefore improve the wiping effect.
- The applicant also found that using a feeding mechanism to deliver the cleaning belt can prevent the cleaning belt from falling off. Pressure of a pressing module and a pressing sheet of the feeding mechanism can be adjusted, and a wiping process can be monitored in real time, so as to realize a closed-loop control of the pressure. This can not only improve the wiping effect and solve the cross-contamination of an electrolyte, but also improve the utilization rate of the cleaning belt by adopting cutting and feeding mechanisms. A clamp cylinder is used to clamp feeding material, which can prevent the cleaning belt from falling off.
- Based on the above considerations, the applicant found that the use of the feeding and cutting mechanisms not only reduces occupied space, but also improves the utilization rate of the cleaning belt. A finger cylinder clamps the cut cleaning belt and sends it to the corresponding position, then the hollow wiping structure descends, and the porous profiling wiping head rotates to carry out wiping while absorbing the residual liquid, which not only reduces cross-contamination of the electrolyte, but also improves the wiping effect.
- According to an embodiment disclosed in the embodiments of the present application, a rotary wiping structure is provided with a servo motor having a module movement on upper and lower sides, so that pressure and a wiping process of the cleaning belt are precise and controllable. Multiple holes and grooves are designed in the middle of and around the profiling wiping head, which can accelerate the removal of residual liquid.
