Mechanical spraying device, spraying mechanical arm and automatic spraying method

Abstract

The invention is suitable for the technical field of mechanical arms, and provides a mechanical spraying device, a spraying mechanical arm and an automatic spraying method. The mechanical spraying device comprises a mounting seat and a spraying part used for spraying powder, the mechanical spraying device further comprises a coating assembly, a cleaning assembly and an impurity removal assembly, the coating assembly is arranged on one side, close to the spraying part, of the mounting seat, the cleaning assembly is arranged on one side, close to the mounting seat, of the coating assembly, and the impurity removal assembly is arranged on one side of the cleaning assembly. The cleaning assembly drives the coating assembly to evenly coat the surface of an object with a solvent, recycling is carried out on the solvent output by the coating assembly, then the powder is sprayed to the surface of the object to be sprayed through the spraying part, the powder is bonded to the surface of the object through the solvent, and scraping away is carried out on chippings generated on the outer side wall of the coating assembly are through the impurity removing assembly; and according to the mechanical spraying device, the uniformity of the solvent coating on the surface of the object is guaranteed, removing can be carried out on the impurities generated on the outer surface of a roller in time, time and labor consumed by manpower are reduced, and the spraying quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical arms, and in particular relates to a mechanical spraying device, a spraying mechanical arm and an automatic spraying method. Background technique [0002] With the continuous development and improvement of science and technology in our country, the mechanical arm device has developed rapidly in recent years and is an important part of industrial robots. The multi-axis mechanical arm device, especially the six-axis mechanical arm device, has entered the among major factories; [0003] The existing spraying process is also using the mechanical arm to carry out the electrostatic spraying work, but in the existing powder spraying work, the powder is not easy to stick to the surface of the object to be processed, and now the solvent is applied on the surface of the object to achieve good adhesion ; [0004] However, during solvent smearing, a large amount of glue is easily attached to the roller u...

Problems solved by technology

[0003] The existing spraying process is also using the mechanical arm to carry out the electrostatic spraying work, but in the existing powder spraying work, the powder is not easy to stick to the surface of the object to be processed, and now the solvent is applied on the surface of the object to achieve good adhesion ;

[0004] However, during solvent smearing, a large amount of glue is easily attached to the roller used for smearing. If these glues are not treated, the glue will exist on the outer surface of the smearing roller in large quantities, so that the smearing roller cannot perform uniform smearing work , and during the smearing work, it is easy to adhere the impurities and dust on the outer surface of the article to be processed to the outer surface of the roller, so that the smearing effect of the roller is not good
