摘要：At present, machine fixed up and down repeatedly work is done by human. Although it is low co.t and easy to change plate, there are many shortco.ings of the work injury and the low work efficiency. Foreign automatic loading and unloading device has been developed, but the principle is more co.plex, the co.t is higher, the energy co.sumption is larger, so the automatic loading and unloading robot came into being. Aiming at the transportation of mechanical raw material, an automatic device is designed to transport the scheduled raw materials to the specified position acco.ding to the processing requirements. The device has the characteristics of the simple operation, the rapid response and the large range of activities, and has obvious eco.omic and environmental benefits. There is certain popularization value.
