Automobile body projection welding workstation based on 2D visual guidance

Abstract

The invention relates to an automobile body projection welding workstation based on 2D visual guidance. The workstation comprises a projection welding machine, a nut conveyor, feeding tables and a robot. The projection welding machine and the robot are oppositely arranged, the nut conveyor is arranged on one side of the projection welding machine, and the feeding tables are arranged on the side face of the robot. The robot is provided with a gripper used for gripping automobile body parts on the feeding tables and a first 2D visual guider used for guiding the gripper to grip the automobile body parts, a second 2D visual guider used for guiding the gripper to convey the automobile body parts to the projection welding machine is arranged on one side of the robot, and the gripper, the first 2D visual guider and the second 2D visual guider are all connected to an automatic controller. Compared with the prior art, the welding workstation is good in flexibility, suitable for various types ofautomobile body parts and high in intelligent degree.

Description

Technical field [0001] The invention relates to an automobile body projection welding workstation, and in particular to an automobile body projection welding workstation based on 2D visual guidance. Background technique [0002] Projection welding, as a common resistance welding, is an important car body connection process. Currently, projection welding relies on manual welding, with low automation and poor solder joint efficiency. In addition, the welding quality of projection welding relies on manual monitoring, resulting in projection welding. Welding costs are too high. [0003] A few cases of automatic projection welding rely on mechanical positioning. The automatic station has poor flexibility and complex changeovers. There are too many tooling for changeovers when switching between multiple products, which not only takes up a lot of space, but also leads to an increase in workstation costs. In addition, the relative cost of 3D vision systems is too high, and promotio...

AI Technical Summary

Problems solved by technology

[0002] As a common resistance welding, projection welding is an important body joining process. At present, projection welding relies on manual welding, which has a low degree of automation and poor efficiency of solder joints. In addition, the welding quality of projection welding relies on manual monitoring, resulting in Welding costs are too high

[0003] A small number of automatic projection welding cases rely on mechanical positioning. The automatic station has poor flexibility and complicated model change. There are too many tooling changes when switching between multiple products, which not only takes up a lot of space, but also increases the cost of the workstation.

In addition, the relative cost of the 3D vision system is too high, and the promotion is affected by factors such as cost and failure rate
