Development of Measuring Equipment of Magnetic Field in BIW Spot-welding Environment

Put forward a robot's automatic packaging and palletizing production line based on Modbus fieldbus control system, to improve efficiency of logistics and enhance the intelligence and versatility of packaging and palletizing system. The SIEMENS S7-1200 PLC sequence control is used to achieve the operation of material conveying line and packaging-palletizing line in automatic packaging and palletizing production line. Visual intelligence is used to recognize the information about shape, position and number of the workpieces to be packed. Through information exchange between MODBUS fieldbus and PLC, industrial robots, visual intelligent detection and host computer can enhance reliability and applicability of packing and palletizing system. It has been proved that the method improves the automation degree of the packaging and palletizing production line, the allocation of resources and system layout can be optimized, and the debugging cost can be saved.
