In the modern age, robot automation is much faster and provides more accurate results than manual labor. However, robots are often unable to account for common inaccuracies like incorrect specifications, part tolerance or feeding misalignment. To help compensate for some of these problems and provide a smooth experience to counteract difficult assembly problems, PFA Inc. proudly offers the PFA Accommodator Remote Center Compliance Device.
Center of compliance refers to a defined point in space at the assembly interface. From this point, contact forces and torques generated by mating parts produce rotational and translational movements may be small enough to still allow assembly, but often cause more misalignment that hinders assembly or damages parts and tooling during the process.
The PFA Accommodator Remote Center Compliance Device works between automated assembly operations parts to passively compensate for misalignment issues. This includes support for several types of misalignment including torsional, out of square and lateral. Throughout assembly, the PFA Accommodator Remote Center Compliance Device prevents jamming by minimizing assembly forces, thus reducing the chance of jamming and damage.
For proper functionality, the PFA Accommodator Remote Center Compliance Device is mounted between the tool changer or flexible wrist and the gripper. Through the use of 6 individual shear pads, the device is able to project a predetermined center of compliance remote from the tooling plate where rotational and translational forces are decoupled. At this point, because the device is capable of translating laterally and rotating independently to reduce the forces of misalignment, assembly that requires the use of robotics can be accomplished more easily without jamming.
