Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles, and the like, and a plurality of fields such as military equipment, aerospace, and the like. With the continuous expansion of the application field of the power battery, the market demand of the power battery is also continuously expanding.

The inventors have noted that during the preparation of the battery cell, the electrolyte may adhere to the surface of the battery cell due to process fluctuation, cross contamination of the fixture or probe, and transportation of the battery cell, for example: large surface, side surface, top cover, two-dimension code and other areas on the battery cell. The electrolyte changes over time on the cell, which changes in a liquid-crystallization-corrosion trend, resulting in a continuous increase in the degree of contamination. The battery monomer polluted by the electrolyte can be directly scrapped according to the pollution part and degree, such as two-dimensional codes, pole corrosion and the like; part can be in blue membrane back visual inspection pick, tear film and polish reworking, if: the large surface, side surface, top cover, pollution on the polar post, etc. of the battery cell seriously affect the yield of the finished battery cell.

In order to remove electrolyte on the surface of the battery cell, dust-free paper wiping, dry ice cleaning, laser cleaning and other modes are generally adopted in the prior art. The dust-free paper wiping mode utilizes dust-free paper and DEC/alcohol to wipe the surface of the battery monomer; the dry ice cleaning mode utilizes dry ice to impact the surface of the battery monomer at a high speed, so that the electrolyte expands with heat and contracts with cold, is peeled off from the surface, and is taken away by utilizing air; the laser cleaning mode irradiates the surface of the battery monomer by using high-energy pulse laser to instantaneously evaporate or strip the electrolyte pollution.

However, the dust-free paper wiping mode has poor cleaning effect and is easy to leave white marks on the surfaces of the battery monomers; and the pollutants are easy to splash or transfer to other areas in the cleaning process. The dry ice and the laser cleaning mode are respectively put into valuable equipment such as dry ice, laser and the like, and dry ice resources are required to be continuously consumed in the cleaning process, so that the cleaning cost is too high.

Based on this, the present inventors have conducted intensive studies to design a cleaning device in order to achieve an economical and effective cleaning manner on the surface of the battery cell. The suction opening of the suction nozzle is arranged towards the surface of the battery monomer, and negative pressure is formed in the suction opening by utilizing a power source.

When the battery monomer is cleaned, the adsorption port of the suction nozzle faces to the surface of the battery monomer; and negative pressure is formed in the adsorption port by utilizing the power source, so that electrolyte adhered to the surface of the battery monomer is sucked into the suction cup, thereby realizing effective cleaning of the surface of the battery monomer, reducing scrappage of the battery monomer caused by electrolyte pollution and improving the yield of the battery monomer. Compared with the traditional cleaning mode, the utility model cleans the surface of the battery monomer by utilizing negative pressure adsorption, does not need to input expensive equipment such as dry ice or laser and the like, and is beneficial to reducing the cleaning cost of the battery monomer. Meanwhile, the utility model adopts a negative pressure adsorption mode, so that pollutants cannot be splashed or transferred to other areas of the battery monomer in the cleaning process, and the cleaning effect of the battery monomer is improved.

In addition, in the cleaning process, the adsorption port of the suction nozzle faces to different areas on the surface of the battery monomer, and different parts on the battery monomer can be cleaned, so that the problem that the traditional liquid injection port is cleaned is solved, and the cleaning in a large range is realized, for example: the suction nozzle is respectively acted on a large surface, a side surface, a bottom surface, a two-dimensional code area and the like of the battery cell, and can carry out negative pressure cleaning and the like on electrolyte pollution of the battery cell by 100 percent.

The movement of the blocking member 320 may be rotation, translation, etc. Meanwhile, the third driver 310 may be a cylinder, a hydraulic cylinder, an electric cylinder, or the like; the motor and transmission structure may be combined, for example: the third driver 310 may be a motor and gear set structure, a motor and belt roller combination structure, etc. In particular, in some embodiments, the conveying mechanism 200 is provided with two supporting members at intervals along a direction perpendicular to the conveying direction X, and the blocking member 320 is rotatably connected to one of the supporting members. The third actuator 310 drives the blocking member 320 over or off the other support member to perform a stopping or releasing action. Of course, to facilitate stable overlapping of the blocking member 320 on the supporting member, a groove or the like may be provided at one end of the supporting member.

The stopping mechanism 300 is utilized to ensure that the battery unit 400 accurately stays on the cleaning station, so that the cleaning device 100 can conveniently clean the battery unit.

Referring to fig. 1 and 2, the present utility model provides a cleaning device 100, a battery unit 400 passes through the cleaning device 100, a power source 20 generates a negative pressure with a certain pressure (the negative pressure is adjustable, and the range is 0Mpa to 0.1 Mpa), a suction nozzle 10 sucks electrolyte on the surface of the battery unit 400 through the negative pressure, wherein the distance between the suction nozzle 10 and the surface of the battery unit 400 is adjustable, and the range is 0cm to 5cm. Meanwhile, the mixture of the electrolyte waste liquid and air is separated by the gas-liquid separator 30, the waste liquid is collected by the collector 40, and the collector 40 can be replaced periodically.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict. The present utility model is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
