A body intelligent identification method and identification system in an automobile production line

Abstract

The invention discloses an intelligent identification method and an identification system for a vehicle body in an automobile production line. The method includes: S1. forming corresponding model car body image sets for different types of car bodies and storing them in the storage database of the cloud platform; S2. taking the image of the car body to be recognized at the entrance of the previous production line according to the optimization prompt information; S3. The body image to be recognized is searched and compared in the model body image set according to a priority order. If the comparison similarity of any body image to be recognized reaches a preset threshold, the corresponding unique identification code of the body is called; S4. Calculate the body The time T from the entrance of the front production line to the exit is corrected to form the corrected time T1. When T1 is reached, a driving signal is output to drive the body distribution device to transport the body to the rear production line corresponding to the unique identification code of the body. The invention is simple and convenient, is suitable for automatic production, and avoids errors caused by manual operation or mechanical certification.

Description

technical field [0001] The invention relates to the technical field of automobile production, and more specifically relates to an intelligent identification method and identification system for a vehicle body in an automobile production line. Background technique [0002] At present, automobile manufacturers have established and perfected the production management system. The general automobile production process includes five processes, that is, the stamping process for producing stamped parts of each body, and the welding process for welding each stamped part into a complete body. The painting process of spraying the body, the assembly process of assembling the body, chassis and interior and other parts to form a complete vehicle, and the inspection process of inspecting the vehicle to find potential quality problems in the production and assembly process. Among them, the automobile body welding process is an important project in the manufacture of automobiles. The basic p...

Problems solved by technology

[0003] However, in the automobile manufacturing production line, with the increase of the scale and production capacity of the car factory, there will often be one front production line corresponding to two rear production lines, such as one painting production line corresponding to two final assembly production lines, that is, in the body supporting device (such as: body sled) After the painting is completed, the body on the body) is transported to the two assembly lines through the body diverting device (for example: a rotating roller bed). At present, manual identification is used, which is prone to errors and affects production efficiency. Chinese patent 2011204556634 discloses a A vehicle body identification control shunt device is controlled by a signal board and a magnetic sensor. This method is limited by the installation position of the signal board and the magnetic sensor, and errors often occur during production.
