The work aims to improve the packaging efficiency and quality of GBD, reduce the repetitive work, lower the labor intensity in production process and decrease the enterprise production costs according to the design requirements of GBD robot automatic packaging production line for three-way catalytic converter in China VI vehicle emission standards, so as to shorten the cycle of the production line and enhance the level of automation. The electrical system of production line was designed and the traditional single PLC control method was changed. On the basis of the original packaging production line, the key technology of multi-PLC control system was realized, so the electrical system for GBD robot automatic packaging production line was developed. Through the operation in actual production, the electrical system effectively improved the packaging efficiency of the production line, shortened the production time of single-carrier single shrinkage whole line from 60 s to 45 s, and effectively enhanced the packaging efficiency of the production line. Practice has proved that the GBD packaging production line can run smoothly and can significantly improve the automation level of the enterprise.
