A kind of automobile coating production line

Abstract

An automotive painting production line, comprising a part feeding and discharging workbench (1), a pretreatment room (2), a painting room (3), a drying room (4), an electric controller (5), and a conveying mechanism (6). A stopping module, a walking module, and a speed reducing module are used for controlling starting, stopping, and speed reducing of a drive motor correspondingly, so that the durations during which an automotive part stays on the part feeding and discharging workbench, in the pretreatment room, in the painting room, and in the drying room can be controlled. By means of the coordinative provision of an RFID information recognition module and an RFID electronic tag, the position to which a conveying device conveys the automotive part can be detected in advance, so that the conveying mechanism can be stopped on the part feeding and discharging workbench, or in the pretreatment room, or in the painting room, or in the drying room by means of the speed reducing module and the stopping module. By means of the coordinative provision of a wireless information receiving module and a wireless information transmitting device, running and stopping of a moving mechanism can be remotely controlled, and running and stopping of the conveying mechanism can be remotely controlled. Thus, the automotive painting production line can be suitable for painting operations of different automotive parts, and the applicability of the production line is improved.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, and the specific field is an automobile painting production line. Background technique [0002] The automobile painting process can generally be divided into two parts: one is the surface treatment of the metal before painting, also called pre-treatment technology; the other is the construction process of painting. Surface treatment mainly includes the removal of oil, dust, rust on the surface of the workpiece, and the removal of the old paint layer during repair work, so as to improve the surface condition of the workpiece. Including mechanical processing and chemical treatment of the workpiece surface according to various specific conditions, such as phosphating, oxidation and passivation treatment. The traditional painting process of auto parts has many shortcomings due to the relatively primitive manual spraying method. The conveying mechanism in the production line is unstable, ...

AI Technical Summary

Problems solved by technology

The traditional coating process of auto parts has many shortcomings due to the relatively primitive manual spraying method. The conveying mechanism in the production line is unstable, resulting in low production efficiency and low degree of automation. The spraying process cannot achieve continuous production. Workers The labor intensity is high, and the pretreatment time, spraying time and drying time are different for different types of auto parts, and the running speed and residence time of the fixed conveying mechanism cannot adapt to the spraying operation of different types of auto parts
