IAI Industrial robots have launched a new range of servo actuators with an integrated load cell: ServoPress actuators.
The actuator is composed of a 230V servomotors with absolute encoder, a ball screw spindle and a rod with a load sensor. These devices help easily realize press applications with their accurate position control, and a pushing force.
The servo press functionality gives superior stability during pressing, making the actuator optimal for simultaneous push and motion. The servo press actuator can be used for a large number of different applications that require a strong pushing force, such as a press fit and sealing.
Force Control is a function that can execute very precise pressure force using the feedback data of the special load cell installed in the actuator. With the special press program software from IAI, different push-motion operations can be performed.
The actuator is equipped with a special load cell on the rod tip to detect the load applied to the pressed object. This provides an extremely precise load control with a repeat accuracy of ± 0.5% F.S. (Full Scale).
These actuators can be used for applications where the time is reached until a predetermined pushing force is undetermined, such as: compression molding of powders; applications where the pushing force is maintained from the pressurized state to cooling, such as welding with hot plates; and applications where the pushing force is maintained for a predetermined period such as the strain relief of the workpiece.
