Study On The Double-direction Automatic Grafting Machine

In order to improve grafting efficiency, the double-direction automatic grafting machine is designed and manufactured based on the former automatic grafting machine. This grafting machine can be used to graft seedlings by sticking them together. By the double symmetric arms, which distributing in two directions and working at the same time, the grafting machine's efficiency can be improved much more.The thesis does whole distribution design to the double direction grafting machine, and does deep study to the conveying mechanism of the stock seedlings and scion seedlings and to the cutting mechanism. In the grafting seedlings conveying system, the photo electricity sensor is used to confirm the beginning position, and stepping motor is used to control the running of the conveying mechanism of the stock seedlings and scion seedlings, and so the grafting orientation precision is elevated. Pro-E, one of the three-dimensional CAD software, is used to do the mechanism design in the whole machine's design. After the function analysis of the machine's control system, the control system is designed by PLC. And detailed research is done to the hardware and the software of the control system. It has been approved by the experiment that the machine can accomplish the grafting task successfully and improve grafting efficiency evidently.
