Body-in-white information management method and system

Abstract

The invention provides a white vehicle body information management method and a system. The method comprises the following steps: according to the manufacturing process of a white vehicle body, an upper computer receives a production line welding parameter, a bolt torsion value, surface quality information and key size information of the white vehicle body in real time; a visual management interface is generated according to the production line welding parameter; a bolt is retightened according to the bolt torsion value; the surface quality information is associated with a corresponding net region of a white vehicle body view after net region division; and the key size information is associated with a corresponding size line of the white vehicle body view marked with the size line for display. The method can realize online information management, including the surface quality information, the key size, the production line welding parameter and the bolt torsion value of the white vehicle body, and prewarning, can improve stable, effective, comprehensive and accurate control of the quality of the white vehicle body, improves the quality control efficiency, reduces the staff waste, reduces the cost, and achieves the quality tracing and inquiring functions.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a body-in-white information management method and system thereof. Background technique [0002] In automobile body production enterprises, the manufacturing process of body-in-white usually includes: solid spot welding, sub-assembly welding, assembly welding, secondary welding repair welding, drilling, door assembly, grinding, kneading, wiping, Sheet metal repairs are off-line, and according to the normal manufacturing process, the quality control methods of the body-in-white are: test piece test, chisel inspection test, three-coordinate inspection of the head and tail table, ordinary pneumatic wrench tightening hinge bolts or fixed torque wrench tightening bolts, record sheet Quality problems are recorded by hand, and then manually sorted into electronic files. This kind of body-in-white quality control method is too dependent on the sense of responsibility of personnel,...

Problems solved by technology

This kind of body-in-white quality control method is too dependent on the sense of responsibility of personnel, which is not only inefficient, but also increases the cost, and the quality stability of the body-in-white cannot be controlled (for example, the quality of solder joints cannot be controlled, the surface quality cannot be controlled, Hinge torque value cannot be controlled, size detection is off-line sampling and cannot be controlled, etc.), it is difficult to form a quality database, there is no quality traceability, poor timeliness of quality supervision, poor sharing, etc.
