Technical Field
The utility model belongs to the technical field of winding vacuum coating, and particularly relates to a cleaning module for winding coating equipment.
Background
In the production process of winding evaporation coating, in order to prevent the high temperature generated in the evaporation process and the damage of the evaporation material to the flexible film outside the cooling protection range of the coating main roller, a baffle plate is usually arranged in the winding coating equipment to separate the evaporation coating area from other areas. However, in the vacuum coating process, when the evaporation source is started to perform evaporation coating on the flexible base film, evaporation materials with a certain thickness are also adhered to the baffle, and when the adhered evaporation materials on the baffle reach a certain degree, the evaporation materials fall off due to internal stress or cold and hot impact, so that the coating environment is polluted, and the quality of a film product is influenced.
In order to avoid the above problems, it is generally necessary to periodically clean the baffle plate in the roll coating apparatus, or to provide the baffle plate with a backing plate and clean the backing plate. At present, the design of a fixed baffle is usually adopted in a single-chamber winding film plating machine with more applications or a lining plate is arranged on the fixed baffle, when the baffle or the lining plate is cleaned, the baffle or the lining plate is usually required to be detached from equipment, and the cleaning is carried out outside the winding film plating by adopting modes such as sand blasting, manual polishing or high-pressure gas purging, the cleaning mode is time-consuming and labor-consuming, the problems of incomplete cleaning, secondary pollution to the baffle or the lining plate, damage to the surface of the baffle or the lining plate, air entrapment and influence on the vacuum degree and the like can also exist, and hidden danger is brought to the stable film plating production. Particularly, in high-end multi-chamber winding vacuum coating equipment for producing an electrode layer of an automobile power battery, the traditional cleaning method can increase the chances that a coating vacuum area and a coating core component are exposed to the atmosphere and polluted by the atmosphere, influence the quality stability of a film product and be not beneficial to the implementation of high-end intelligent winding coating equipment in high-end automatic production.
SUMMERY OF THE UTILITY MODEL
The utility model provides a cleaning module for winding coating equipment, which mainly comprises a cleaning action surface and a dry ice supply source; the cleaning action surface is arranged in a vacuum chamber of the winding coating equipment, and a cleaning phase is arranged above the cleaning module and close to the cleaning action surface; when the movable baffle moves to the cleaning phase under the driving of the moving mechanism, the cleaning module cleans the attachments on the movable baffle in a vacuum environment.
The upper surface of the cleaning action surface is an inwards concave arc-shaped curved surface; a nozzle array composed of a plurality of rows of nozzles is arranged on the upper surface of the cleaning action surface, and the orientation of the nozzles is the normal direction of the upper surface of the cleaning action surface.
One end of the cleaning action surface, which is vertical to the arc-shaped curved surface bus, is provided with a row of purging nozzles, and the end of the cleaning action surface, which is opposite to the row of purging nozzles, is provided with a collecting tank.
Enclosing plates are arranged on four side edges of the cleaning action surface, so that a relatively independent space is formed when the cleaning module cleans the movable baffle; the dry ice supply source is arranged outside the vacuum chamber and is connected with the cleaning action surface.
When the cleaning module cleans the movable baffle in the cleaning phase, dry ice particles are sprayed to the lower surface of the movable baffle through the nozzle array for cleaning, and cleaning products falling on the cleaning action surface are swept to the collecting tank through high-pressure gas blown by the sweeping nozzle for collection. The nozzle array sprays dry ice particles for cleaning and the blowing nozzle blows high-pressure gas for blowing and sweeping alternately; the dry ice particle spraying speed is not lower than 9 m/s.
When the movable baffle is in the cleaning phase, the distance between the lower surface of the movable baffle and the upper surface of the cleaning action surface is less than 35 mm.
