Abstract: Since the artificial resistance spot welding operation and equipment used in the welding production of automobile enterprises will exist for a long time, how to realize the intelligent manufacturing upgrade of the corresponding equipment and improve the automation rate is an urgent problem for most enterprises. This paper introduces a development and application scheme which is quick and simple, and can realize the upgrading of manual spot welding equipment at low cost, and improve the level of equipment automation and operation quality. In this scheme, a sensor and signal transmitter with product difference recognition are added to the fixture to realize the automatic recognition and transmission of the target product model. The installation of different types of sensors can basically cover all product differences, and the automatic identification range is wide and the identification reliability is high. By adding signal receiving and signal processor to the welding equipment, the wireless signal receiving and welding signal comparison and analysis can be realized,and then the automatic selection of welding program can be completed. Through the increase of the above devices, the production line can be rapidly upgraded and the automation level and quality level of the production line can be improved.
