Mechanical arm control device and method for electrostatic spraying of automobile parts

Abstract

The invention discloses a mechanical arm control device and method for electrostatic spraying of automobile parts. The mechanical arm control device comprises a spraying mechanism, a mechanical arm mechanism and a main controller, wherein the spraying mechanism is connected with the mechanical arm mechanism, the spraying mechanism comprises a conveying main body, a spraying cup and a mixer are installed at the upper end and the lower end of the conveying main body correspondingly, a powder pipeline and an air pipeline are arranged on the left side and the right side of the lower portion of the mixer respectively, the upper end of the powder pipeline and the upper end of the air pipeline are both connected with the mixer, and a plurality of conveying channels are arranged in the conveying main body. According to the mechanical arm control device and method for electrostatic spraying of the automobile parts, surface shape information of a workpiece to be sprayed is recognized, and flow control valves are controlled to act according to the surface shape information, so that the output speed of the conveying channels is flexibly adjusted, it is guaranteed that the speed of electrified coating powder reaching the sprayed workpiece is constant, and the coating powder can be uniformly and stably sprayed on the workpiece to be sprayed.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying, in particular to a mechanical arm control device and control method for electrostatic spraying of auto parts. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make the negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. High efficiency and other advantages; [0003] At present, electrostatic spraying equipment is generally composed of spray guns, spray cups, and electrostatic spraying high-voltage power supplies. It has good uniformity when electrostatically spraying flat workpieces. There is a difference in the distance between the spraying area and the spraying equipment, which causes the impact force of the paint powder to move to different smaller unit areas in the same spraying area to be differe...

Problems solved by technology

[0003] At present, electrostatic spraying equipment is generally composed of spray guns, spray cups, and electrostatic spraying high-voltage power supplies. It has good uniformity when electrostatically spraying flat workpieces. There is a difference in the distance between the spraying area and the spraying equipment, which causes the impact force of the paint powder to move to different smaller unit areas in the same spraying area to be different, so that the uniformity of the paint powder adhering to the workpiece is inconsistent. Therefore, the present invention A mechanical arm control device and control method for electrostatic spraying of automobile parts is proposed to solve the problems existing in the prior art
