A robotic arm control device and control method for electrostatic spraying of auto parts

Abstract

The invention discloses a mechanical arm control device and a control method for electrostatic spraying of automobile parts, comprising a spraying mechanism, a mechanical arm mechanism and a main controller, wherein the spraying mechanism is connected with the mechanical arm mechanism, and the spraying mechanism comprises a conveying body, and the spraying mechanism comprises a conveying body. The upper and lower ends of the conveying body are respectively equipped with a spray cup and a mixer, and the left and right sides below the mixer are respectively provided with a powder pipeline and an air pipeline, and the upper ends of the powder pipeline and the air pipeline are both connected with the mixer. The main body is provided with a conveying channel, and the conveying channels are provided with multiple groups. The mechanical arm control device and control method for electrostatic spraying of automobile parts recognizes the surface shape information of the sprayed workpiece, and controls the flow control valve action according to the surface shape information. The output rate of the conveying channel can be flexibly adjusted, so as to ensure that the speed of the charged paint powder reaching the sprayed workpiece is constant, and then the paint powder can be uniformly and stably sprayed onto the sprayed workpiece.

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 automobile parts. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the opposite direction of the electric field, and adsorb the paint particles on the surface of the workpiece. High efficiency advantages; [0003] At present, electrostatic spraying equipment is generally composed of spray guns, spray cups and high-voltage power supplies for electrostatic spraying. There is a difference in the distance between the spraying area and the spraying equipment, which causes the impact force of the coating powder to move to different smaller unit areas in the same spraying area is not the same, so that the uniformity of the coating powder on the workpiece is incons...

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
