Multiple automobile mode discrimination and control method of automobile body locus line

Abstract

The invention relates to an automobile body painting production line, in particular to a multiple automobile mode discrimination and control method of an automobile body locus line. When a white automobile body is positioned on an overhead midline, white automobile body information is loaded to an overhead locus PLC by a scanning device, and holding tool pivot point information obtained by a holding tool pivot point discriminating system is also input to the overhead locus PLC; the overhead locus PLC compares the white automobile body information and the holding tool pivot point information, if a holding tool pivot point meets an automobile mode of the white automobile body, a holding tool enters a loading lifter of the white automobile body and automatically hangs the white automobile body into the holding tool and loads the white automobile body information into a code carrier of the holding tool, and if the holding tool pivot point can not meet the automobile mode of the white automobile body, an audible and visual alarm sends alarms; persons adjust the holding tool pivot point to enable the holding tool pivot point to be matched with the white automobile body, and the white automobile body is hung into the holding tool after being determined, and the white automobile body information is also loaded into the code carrier of the holding tool. The invention can enhance the utilization rate of the painting production line and lower the labor intensity of operating staff.

Description

technical field [0001] The invention relates to a multi-vehicle discrimination and control method of a mechanized transportation device in a multi-vehicle co-line production mode in an automobile body painting production line. Background technique [0002] The competition in the automobile market is becoming increasingly fierce, and more and more automobile manufacturers adopt the marketing method of continuously launching new models to attract consumers and expand market share. Small-batch and multi-variety production of vehicle models is the mainstream of the current automobile production line. This requires the automobile body painting production line to have the ability to produce multiple models in one line. [0003] A production line often has to undertake the production tasks of three or more models on the same line, especially for models with different development platforms, the fulcrum positions of the vehicle body vehicles transported by air and ground are differe...

AI Technical Summary

Problems solved by technology

[0004] The existing car body machine transportation line has to go through the process of the car body going up to the air, completing the pre-treatment electrophoresis in the air, going down to the ground to complete the surface spraying, and then going to the air to complete the final assembly in the air. Vehicle body vehicles generally use fulcrum flipping, bending, plugging and other methods to adjust the distribution of fulcrums, which has high requirements for the measures and judgments of adjusting fulcrums, so as to avoid damage to the body caused by wrong fulcrums and low production efficiency

The existing multi-vehicle identification and control method of automobile body machine transportation line adopts the method of manually identifying the fulcrum, which is unreliable and error-prone, especially in the mixed production mode with similar vehicle types, the rate of damage to the body often occurs due to manual judgment errors
