Flexible welding system capable of horizontally rotating and shifting car models

Abstract

The invention discloses a flexible welding system capable of horizontally rotating and shifting car models. The flexible welding system comprises one or more welding robots, wherein a welding work table for allowing work pieces to be placed is arranged on one sides of the welding robots; a guard fence is arranged around the welding robots and the welding work table, and a manual piece taking and placing opening is formed in the guard fence, manual guardrails, a safety light curtain, a foot light curtain and an operation panel are arranged at the manual piece taking and placing opening; a robot control cabinet and a welding work table control cabinet are arranged on the outer side of the guard fence; the welding robots are connected with the robot control cabinet; the welding work table is connected with the welding work table control cabinet; and a welding clamp set comprises a horizontal rotating clamp set and a fixing clamp set. According to the flexible welding system disclosed by the invention, the applying deficiency of intelligent robots in the field of manufacturing of automobiles is sufficiently considered; the work table capable of horizontally rotating and shifting the car models is allocated for the robots, so that under the premise that the reforming degree of a robot welding system is minimum, multi-car-model flexible production is realized; and the flexible welding system is low in occupied area, high in production efficiency, high in automation degree and good in compatibility, can be matched with other automated production equipment for use, and can be greatly applied in the layout situation with large horizontal space.

Description

Technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a switching flexible welding system for a horizontally rotating vehicle type. Background technique [0002] In the current automotive welding equipment field, in order to improve production efficiency, improve welding quality, improve working environment, and reduce labor intensity and production costs, robotic welding technology has been widely used. [0003] However, the existing automated welding system has large investment, single application varieties, low robot efficiency in the automated welding system, and long flexible switching time of the production line, resulting in low welding efficiency. In addition, the identification of the type of flexible switching requires manual participation. Many unstable factors have come.

Problems solved by technology

[0003] However, in the existing automatic welding system, there are large investment, single application variety, low efficiency of robots in the automatic welding system, and long flexible switching time of the production line, resulting in low welding efficiency. There are many unstable factors

[0004] At present, flexible welding and welding production lines at home and abroad are basically used in large-scale vehicle production lines to meet the flexible production of two or three models. The main method is to dynamically identify the models and then replace the corresponding tooling to realize the positioning welding of different models. It is a large-scale complete vehicle with a relatively large volume, and generally adopts an assembly line single-line production mode, which takes up a relatively large space

For the welding assembly of small assembly parts, due to the small size of the parts themselves and few solder joints, it is difficult to realize the automatic welding of robots on large-scale production lines

[0005] On the other hand, since the welding robot moves under the guidance of the preset program, the position and trajectory of each welding point are accurately determined, so the workpiece needs precise positioning to complete the welding when using the welding robot. The positioning of the workpiece is mainly through the complex and diverse fixture system, and the fixture system is often specific, which causes the welding robot to manually replace the fixture system when producing different workpieces, which is time-consuming and laborious

If multiple sets of fixture systems are set up around the robot, it will cause a waste of space
