Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a liquid injection nozzle cleaning tool assembly. Background Art

[0002] In the battery manufacturing process, cell injection undoubtedly occupies a core position. Its technology has gone through multiple rounds of iterations such as normal pressure, negative pressure, and isobaric injection, and has developed to be quite mature. The core goal has always been to accelerate the infiltration of the pole pieces to achieve a leap in production efficiency. The injection process is delicate and complex, and includes two crucial steps: one is to accurately inject a specified amount of electrolyte into the battery cell, and the other is to ensure that these electrolytes can achieve comprehensive and uniform infiltration with the pole pieces and diaphragms in the battery cell. This link has immeasurable value to the performance and safety of the battery. The quality of the electrolyte, as the conductive and ion exchange medium inside the battery, is directly related to the overall performance of the battery. Therefore, the precise control of the injection technology has become a key in the cell manufacturing process.

[0003] To achieve this goal, modern battery production lines use highly specialized injection devices that integrate multiple precision components such as injection nozzle structure, vacuum processing system, injection valve, and injection workstation. However, in actual production applications, the injection nozzle is prone to clogging due to long-term contact with electrolyte and possible impurities, which not only affects the accuracy and efficiency of injection, but also poses a potential threat to the quality of the battery. Therefore, regular and effective cleaning and dredging of the injection nozzle has become a key link to ensure the continuity and stability of the injection operation. By adopting advanced cleaning techniques and equipment, such as high-pressure water gun flushing, ultrasonic cleaning, or soaking in special cleaning agents, it can be ensured that the injection nozzle is always kept clean and unobstructed, thereby ensuring the smooth progress of the entire battery cell injection process and the high-quality output of battery products.

[0004] Patent document CN115475795A discloses a cleaning mechanism for a battery cell injection nozzle; a cleaning container assembly and a cleaning container motion assembly are provided, and a driving assembly in the cleaning container motion assembly drives the cleaning cup body in the cleaning container assembly to move in the X-axis and Z-axis directions with the injection nozzle as the center, so that the injection nozzle completes the cleaning operation in the cleaning cup body. Secondly, by opening a three-dimensional through hole in the cleaning cup body, the injection nozzle can pass through the cleaning cup body to perform injection operations. When the injection nozzle has finished injecting liquid, the driving assembly can drive the cleaning cup body to clean the liquid at the injection nozzle in time when the liquid has not crystallized, thereby increasing the cleaning effect of the injection nozzle and preventing the crystals at the injection nozzle from falling into the injection cup after crystallization, causing the injection port in the injection cup to be blocked, affecting the injection amount of the battery cell, thereby producing defective products and causing waste of resources.

[0005] As in the prior art of the above-mentioned patent, the above-mentioned device is a liquid injection nozzle cleaning device, and the liquid injection nozzle is cleaned by a cleaning device, but this cleaning method can only clean the surface of the liquid injection nozzle and cannot reach into the inside of the pipeline for cleaning. In order to be able to deeply clean the inside of the liquid injection nozzle pipeline in the prior art, the liquid injection nozzle is generally flushed by a high-pressure spray cleaning device to achieve the effect of cleaning and preventing blockage. However, if the cleaning liquid remaining in the liquid injection nozzle is not discharged in time, it will affect the liquid injection nozzle again, and the cleaning liquid may also be accompanied by some impurities, such as precipitated electrolyte crystals or raw material residues, which also need to be cleaned in time.
