Active Compliance Force Device

The PushCorp AFD620 Series Force Device is a more powerful and rugged tool then the AFD310. This unit was developed in response to customer's needs for increased force capacity and carriage stroke.

The AFD620 Series is available in two configurations: AFD620-1 Vertical and the AFD620-2 Horizontal. The units are functionally identical, but differ in the orientation with which they attach to the robot, either vertically or horizontally. This allows you to optimize robot reach and dexterity for your particular application.

The AFD620 Series coupled with the FCUFLEX Controller allows for incredibly accurate performance. This superior performance benefits you by immediately providing greater processing throughput with more consistent, higher quality results.

Here are just a few operations the AFD620 Series, matched with the proper process equipment, can accomplish faster, more accurately, and with greater control than ever before:

  • Grinding
  • Deburring
  • Polishing
  • Drilling/Chamfering (thru-hole, to-depth)
  • Weld Shaving
  • Any other process which requires an accurate, compliant, continuously adjustable applied force.

The AFD620 Series Compliant Force Device uses an active closed-loop control scheme where, the it works in concert with a remote FCUFLEX Active Compliance Controller. This controller executes proprietary algorithms and continuously monitors the force applied to the work surface via a precision load cell. By immediately correcting any detected force variation, this advanced technology allows the AFD620 Series to apply forces accurate to within ±0.4 lbs. [±2.0 N] over their entire operational force range.

Active compliant force control provides many useful features. The AFD620 Series have the built-in ability to precisely weigh the process equipment and compensate for gravity induced forces in any orientation. This means that if you want to apply 8.2 lbs. [36.5 N] of force to a surface, then the AFD620 will apply 8.2 lbs. [36.5 N] in any orientation; horizontal, vertical, even upside-down, without

any additional integration effort from you. In addition, force variations due to acceleration effects are automatically corrected allowing you to use much higher speeds over contoured surfaces and around corners.

Integrating the AFD620 Series system into your workcell could not be any easier, since the system is completely stand-alone and is not robot dependent. The installation setup consists of mounting the FCUFLEX Controller, attaching one small flexible air supply line, mounting the AFD620, and connecting the supplied controller cable to the AFD. The simple software setup means that you can be up and running your process in a matter of minutes.

All these features combine to make the PushCorp AFD610 Series the most advanced, dependable, and cost effective force control system available today.
