Pre-study on Profile Steel Feeding Robot

In our country,the profile-processing machines in shipyards,such as welding machine,cutting machine and bending machine,are often fed or unloaded with the cranes.Cooperated with cranes,the operators can simply use a length of cable to hold,lift and transfer the workpieces in vertical and horizontal paths.However,swing motion and rotation are generated because of profiles' weight center and length,and it is rather difficult to control them and to obtain accurate located position and to finish the feeding favorably.Meanwhile,starting or stopping cranes and manual controlling the transit routes may bring uncertainty and blindness,which results in the low efficiency,the waste of electrical power and the increase of ship-building cost.Furthermore,operators must handle heavy profiles to suppress vibration and to position them.These tasks are danger for operators.Therefore,a robot technology is introduced to replace the traditional cranes feeding and unloading profiles.The high-performances of robots,such as excellent repeatability,positioning accuracy,and high-speed motion,contribute to increasing the profile-processing efficiency,reducing the ship-building cost,and liberating the operators from the danger working conditions.This paper puts forward a design on automatic transfer and feeding robot,and describes the design principle of the main structure,computer vision orientation and the control method in detail.It puts technical discusses on the transit robot for the over-long heavy profiles steel,and tries to entirely realize the full automation of profile process and sets up the automatic profile process line.
