Home / Robotic Arms / EPSON Robots / Force Sensor

Epson robots with force and torque sensors efficiently automate even the most challenging tasks, which up till now have been carried out manually. When handling sensitive components in particular, the ability to reach the robot, in conjunction with image processing systems, is frequently insufficient to attain the desired result. Here, it is advantageous to also recognize the smallest of force changes, and react accordingly.

 The Epson Force Sensor is installed between robot hand and end-effector. It can capture both forces and torques in all three spatial directions. The sensor’s Force Controller provides measurement data - forces and torques – to both the Epson robot control, as well as the user.

ADVANTAGES:

  • Assured compliance with specified tolerances and pressing forces.
  • Avoidance of damage and wear to workpieces and machines.
  • Efficient automation of complex and challenging tasks.
  • Increased flexibility with no change of devices or taught positions.
  • Reduction of subsequent quality inspections with minimal corrections.

 

HIGH RIGIDITY AND SENSITIVITY:

High Rigidity:

Epson Force Sensors are particularly robust and durable, and have exceptional shock and temperature resistance. Even at significant force and torque forces, the displacement of sensors is minimal.

High Sensitivity:

  In comparison to competitor products, the digital noise in Epson sensors is extremely low at just 0.035N. This results in a measurement resolution of just 0.1N with XYZ components. This measured value level enables forces to be captured with superior sensitivity.

The Epson force and torque sensors meet your unique application requirements, with both 6-axis and SCARA robots. In addition, they can also be used with cleanroom version robots – and in particular for C8 series robots.

 

APPLICATION EXAMPLES:

  1. Precise tightening of the smallest of screws:
  2. Installation of components with reduced clearance:
  3. Insertion of connectors:
  4. Use of electronic components with flexible lead wires:
  5. Sensitive force control for polishing tasks:

1. Even the smallest screws, thanks to the force/torque sensors from Epson, can be tightened precisely. Extensive teaching becomes superfluous, as the robots determine successful execution of a task by examining the force applied during its application.

2. The installation of parts with low clearance – such as insertion of pins or transmission components – can now be automated, thanks to the low sensor deflection and outstanding response sensitivity of the Epson sensor. Thus problems with tilted workpieces or jammed parts become a thing of the past.

3. Insertion of connectors in various configurations can be automated easily. Epson sensors detect misalignment between connector and socket by force effort, and provide the robot with feedback to correct the alignment. Thanks to the extremely high sensor sensitivity, the connector is inserted in the socket with no damage.

4. The Epson force sensors are excellently suited for the insertion of workpieces with unusual outer contours. An excellent example is electronic components with lead wires. Using its sensitive sensor, the robot simply “searches” for the hole for the lead wire, and then correctly routes it without bending it.

5. Even polishing, in which the precisely applied force of people has been required, can be automated with uniform and consistent quality by reproducing the desired force using the sensor.
