Embodiment Construction

[0026] refer to figure 1 , a method for repairing damage by electrostatic powder spraying proposed by the present invention includes the following steps.

[0027] S1. Spray electrostatic powder on the workpiece to be processed, and take the sprayed workpiece as the detection target. In this step, the overall spraying of the workpiece is mainly carried out.

[0028] S21. Preset a three-dimensional coordinate system, and establish a spraying model in the three-dimensional coordinate system.

[0029] S22. Extracting coordinate points on the surface of the sprayed model to synthesize a model mask.

[0030] S23. Perform laser scanning on the detection target, and establish a solid model in the three-dimensional coordinate system according to the scanning result. Infrared laser is used to scan the detection target to ensure scanning efficiency and accuracy.

[0031] S24. Displacing the covering layer until the center point of the covering layer coincides with the center point of...

Abstract

The invention discloses a damage repairing method for electrostatic powder spraying. The damage repairing method comprises the steps that a missing part on a repairing target is determined through three-dimensional modeling and model comparison, and accurate positioning of the missing part is achieved; and then a repairing path is established relative to a point coordinate set of an entity model through the missing part, so that the repairing target is automatically and intelligently repaired, working is reliable, and the reliability and the stability of coating repairing are ensured beneficially.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying, in particular to a repair method for electrostatic powder spraying. Background technique [0002] The electrostatic spraying method uses the grounded object to be coated as the anode, the high-voltage electric grid of the equipment as the cathode, and the electrostatic spray gun is connected to a negative high voltage to form a high-voltage electrostatic field between the two electrodes, and the cathode generates corona discharge to charge the sprayed paint particles. And further atomization, according to the principle of same-sex repulsion and opposite-sex attraction, the charged paint particles absorb the coated object along the direction of the electric force line under the action of the electrostatic field, and adhere to the coated object after discharge. [0003] Electrostatic powder coating is one of the major reforms in the coating process. It has developed rapidly with the ...
