Flexible automatic production line of automobile left front girders

Abstract

The invention discloses a flexible automatic production line of automobile left front girders. The flexible automatic production line comprises a PLC control device, a first-region production line, asecond-region production line and a third-region production line. Multiple part feeding stations, multiple welding stations, multiple carrying stations and a part discharging station are arranged on each of the first-region production line, the second-region production line and the third-region production line. Manual part feeding tables are arranged on the part feeding stations. Clamp switching devices provided with part feeding detection inductors and clamp storage devices used for containing multiple types of clamps are arranged on the manual part feeding tables. Welding robots, gripper storage racks used for containing multiple types of grippers and fixed welding guns are arranged on the welding stations. Carrying robots are arranged on the carrying stations. The first-region production line further comprises a gluing station provided with a gluing machine and a conveying station provided with a conveying belt. The third-region production line further comprises an arc welding workbench provided with an arc welding machine and a moving sliding table. The production line can achieve collinear production of multiple s, and more automobile type orders can be borne under the limitedsite and equipment.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a flexible automatic production line for left front longitudinal beams of automobiles. Background technique [0002] At present, the automobile front longitudinal beam welding production line generally adopts the development and layout of the left and right front longitudinal beam assemblies separately. In the current left front longitudinal beam production line of automobiles, most of them adopt the method of one independent production line for one model, and mostly use manual multi-station. Arranging production, the production lines of different models are equipped with the same mechanical and electrical welding equipment, and the switching of models is realized by manually moving the welding fixtures, which can only be adapted to small batches and single model production, and this production method not only occupies Large, large project investment, the actual production ca...
