[Abstract]:Digital assembly and welding workshop shows powerful functions and important value in ensuring the quality stability of welding products, high efficiency of production management and traceability of production failure. The first two-dimension code scanning welding torch control system has been developed independently. The system has the advantages of welding torch scanning, convenient, quick, accurate identification, automatic acquisition, timely delivery, suitable for welding equipment such as robots and special machines, and also applicable to semi-automatic welding equipment. The manual welding machine parameter setting, solves the manual parameter setting error and the error, The digitization and automation of welding process specification parameters have been realized. In this paper, the following research work has been done: 1. 36 sets of hardware system of two dimensional code scanning welding torch are designed, and two kinds of integrated two dimensional code scanning welding torch are designed respectively. The QR QR two-dimension code generation and recognition software system is designed based on the LabVIEW development language, including the injection type integrated scanning torch and the connected type integrated scanning gun, and the QR two-dimension code generation and recognition software system is designed based on the LabVIEW development language. Based on SQL Server and LabVIEW, a two-dimension code weld information database system is developed to store and read weld information. Report form generation and automatic transfer of welding card process specification parameters .3.The welding process specification parameters are automatically issued, including the design of analog signal output module and interface circuit of welding process specification parameters, and the welding current is successfully realized. The stability and reliability of the two-dimension code scanning welding torch control system are tested and verified. Five different content forms and three different sizes of two-dimension code recognition rate and stability are tested and analyzed. For Q235 surface surfacing, the anti-interference ability of two-dimension code in welding process is verified by test; the accuracy and reliability of welding process specification parameters are verified automatically; and the stability and reliability of the system are verified by comprehensive test.
