The automation of machine tool loading and unloading is mainly implemented by truss robot and joint robot. Before looking at more is the truss robot, some people say that the difficulty of automatic loading and unloading is the layout of the station, that is, the planning of the production line, many companies require compact production, the most common is The U-shaped and disc-type cycle type. Workshop is not big enough, rough flow into, finished product outflow management and handling are more expensive space.
Joint robot, for machining machine tool loading and unloading joint robot using the number of shafts is generally 6 axes, repeated positioning accuracy of .06mm, commonly used load weight of 10-50kg. Machine tool loading robot is generally divided into one-to-one, one-to-two, one-to-three, if you want a joint robot to more than one machine tool up and down, need to add the ground track, can achieve a joint robot to multiple machine tools automatically up and down.
The advantages of joint robot, the biggest advantage of joint robot is strong flexibility, not limited by the structure of the machine tool, can be applied to many machine tools. A wide range of applications, in addition to the machine tools used in the material, joint robots can also be used in grinding, polishing, welding, assembly, handling palletizing and other fields.
The shortcomings of joint robot, relative to the truss robot, the joint robot occupies a larger space, its arm extension working range is limited, a machine wants to increase the range of work must be added to its walking shaft, so the joint robot price is higher.
