Method for spraying upper surface and outer side face of workpiece

Abstract

The invention relates to a method for spraying the upper surface and the outer side face of a workpiece. The method comprises the workpiece, a conveying line for conveying the workpiece, a three-dimensional scanning system for scanning the length, the width and the height of the workpiece in the conveying process, a control system for processing scanning information of the three-dimensional scanning system, a first spraying support and a second spraying support, wherein the first spraying support and the second spraying support plan a spraying path through the control system; the first spraying support and the second spraying support transversely slide and vertically move in the workpiece conveying direction under the control of the control system; the first spraying support and the second spraying support are each provided with four spraying guns; and in the one-time conveying process of the workpiece, the four spraying guns of the first spraying support and the four spraying guns of the second spraying support spray the upper side face, the lower side face, the upper surface, the front side face and the rear side face of the workpiece respectively. By means of the method, the spraying efficiency and quality of work can be improved, meanwhile, spraying with the height larger than 5cm of the workpiece can be achieved, and practicability is high.

Description

technical field [0001] The invention relates to a method for spraying the upper surface and the outer surface of a workpiece. Background technique [0002] At present, for the surface spraying of wood workpieces, including the upper surface and the outer surface, usually manual or mechanical equipment is used for spraying. [0003] Manual spraying requires staff to hold spray guns to operate, the spraying efficiency is low, and the spraying is not uniform enough. After spraying, it is dried naturally, causing dust flakes to fall on the surface of the paint, which is difficult to clean, and the dry paint surface is easy to pack. The quality is poor, and the paint is toxic, and working for a long time will pose a threat to the health of workers. [0004] The spraying of mechanical equipment adopts robots to realize automatic operation, but due to the influence of the mechanical structure, its spraying can only meet the workpiece with a height of ≤5cm, but for workpieces with ...

Problems solved by technology

That is to say, the above method can complete the spraying on the upper surface of the workpiece, and considering the effective spraying diameter of the spray gun, the above method can also complete the spraying on the outer surface of the workpiece with less height, but it cannot be sprayed well for the workpiece with a larger height. poor effect
