Description

Automatic coating equipment for automobile bumper Technical Field The invention relates to the technical field of automobile part spraying, in particular to automatic coating equipment for an automobile bumper. Background In the course of the continuing high-speed development of the automotive industry, bumpers are of self-evident importance as core components of the body safety system. In order to improve the durability of the bumper, the spraying process plays a critical role. In the case of coating systems, a "three-coat two-bake" process is generally employed, i.e. the primer, the lacquer and the varnish are sprayed in succession. The primer is used as a coating layer in direct contact with a substrate, can effectively separate the penetration of moisture and corrosive media, the ultraviolet resistance of the paint is enhanced by the colored paint, and a compact protective film is formed by the varnish, so that the corrosion resistance and scratch resistance of the bumper are further improved. Through the fine spraying process, the bumper can keep long-time durability in a complex use environment, effectively resists corrosion of external factors, and provides reliable guarantee for safe operation of automobiles. In a coating process link of modern automobile manufacturing, in order to ensure that paint can be stably and efficiently conveyed to a spray head, a feeding process is often realized by means of a conveying mechanism with larger power, however, in the running process of the mechanism with strong power, high-frequency vibration is inevitably generated, the device can cause irreversible damage to key parts of coating equipment under the long-term action of the high-frequency vibration, the service life of the device is obviously shortened, long-time and large-scale batch spraying production work of an automobile bumper is not facilitated, the complex curved surface of the automobile bumper requires that a spraying system has the capability of adjusting spraying track, angle and flow, and then the existing conveying equipment is difficult to be compatible with a dynamic spraying structure, so that the using effect is poor.
