Description

Technical Field

[0001] The utility model relates to the technical field of automobile welding equipment, in particular to automatic code scanning welding equipment. Background Art

[0002] Welding is a common technique used in industrial production to securely connect individual parts. With the integration and development of CNC and welding technologies, modern welding processes are becoming increasingly mature. Automatic welding equipment can stabilize and improve welding quality, increase labor productivity, and reduce the technical requirements for workers. In the welding of automotive parts, different welding bodies and welding materials require different welding parameters to ensure welding quality. Since many automotive parts require welding, different product numbers are assigned to facilitate traceability. By binding the welding parameters of a part to its product number, users can query the product number to obtain the product's welding parameters. This method is less prone to errors and can prevent operator errors caused by fatigue or carelessness.

[0003] Chinese patent CN206702456U discloses a barcode scanning automatic welding workstation, on which a detachable fixture is provided on the workbench, and a barcode is affixed to the fixture. One barcode corresponds to one welding program, and the fixture corresponds one-to-one with the welding program in the controller through the barcode; the patent realizes automatic welding after scanning the code, but the welding operation is not bound to the product, and the product code cannot be traced back to the welding parameters. In addition, the scanning device in the patent is manually held for scanning, which reduces production efficiency. Therefore, the present application provides a welding device that can automatically scan the code and bind the product code to the welding parameters. Utility Model Content
