Description

Cleaning device

Technical Field

The utility model relates to the field of automobile manufacturing, in particular to a cleaning device

Background

In the industrial production process, because of uncertain factors such as raw materials, transportation, production process and the like, more particles exist on the surfaces of parts or clamps, and the risks of product quality are easily caused. Especially when the shape of the article to be cleaned is irregular, such as deep holes, multi-layer step-shaped drop holes and the like, which are difficult to be contacted by manual or traditional cleaning mechanisms, the article to be cleaned is difficult to thoroughly clean and cannot keep the cleanliness. In addition, in some occasions, the particles are electrostatically charged, and the particles are firmly attached to the surface of the object, so that the cleaning is more difficult. Whereas conventional cleaning schemes have:

(1) And (5) manually wiping. The method adopts manual wiping of the surface of the part, and uses production intervals and maintenance time to clean particles on the surface of the part, such as cleaning cloth, cotton swabs or handheld dust collectors and the like. The method has low cleaning efficiency, and the surface cleanliness of the part or the clamp can be kept only by a worker keeping a certain cleaning frequency;

(2) And (5) cleaning an electric brush. The method utilizes the rotation of a motor to drive a roller brush to repeatedly contact with a part to scrape the part, so as to take away surface attachments. The method is limited by the working characteristics of axial rotation of the hairbrush, so that the irregular surface particles cannot be removed rapidly and effectively, new particles can be caused by abrasion and falling of the hairbrush, and the dead angle of a complex shape is difficult to clean effectively;

(3) And (5) vacuum cleaning. The method utilizes the blades rotating at high speed to form negative pressure, and sucks the particulate matters in the area near the suction head into the collecting cavity. The method can not clean corners, concave surfaces, deep holes, gaps and the like, is also difficult to clean for electrostatically charged particles attached to the surface of a workpiece, and has obvious attenuation of the vacuum cleaning effect for irregular clamps on the surface and areas which are far away from the suction head and cannot be close to the suction head;

(4) Compressed air cleaning. The method comprises the steps of placing a shell to be cleaned above a cleaning mechanism, spraying compressed air to the shell from a plurality of outlets, and enabling particles on the surface of the shell to fall off the shell into a collecting box below the cleaning mechanism by utilizing the compressed air. Although the method can clean the particles at the compressed air spray head to a certain extent, when the particles are inevitably splashed, unpredictable pollution is caused to other areas, and in addition, the scheme does not have corresponding treatment means for common electrostatically charged particles.
