To meet the demand of integral packing machine in actual production, this work aims to design a multi-function integration carton-making and packing machine which can reduce the usage of the assembly line based on infrared induction device. Based on the feature information of the carton making and packing machine, the mechanical system was divided into four parts: infrared induction device, molding device, pushing device and potting device. Technology of infrared induction took singlechip as core and infrared wave as carrier to transmit measurement or control signals. The infrared induction device was the core design. The integral carton making and packing machine based on infrared induction and identification device integrated the operation of carton making, packing and potting. It was able to choose the most suitable size of carton according to the size of the object and finish the work of packing at the time of carton making, realizing multi-function in one single machine. In conclusion, the infrared induction can be used in making cartons and packing to choose the size of them, realize multifunctions on one machine and finally remove line production in packaging process.
