Electric grippers

Product catalog summary
Overview: The YRG Series Electric Grippers are engineered for precision in industrial settings, featuring multi-point position control, speed control, measuring, and gripping force control. They are compatible with RCX240/RCX340 controllers, facilitating integration and operation using YAMAHA robot language.
Specifications: Gripping force is adjustable from 30% to 100% in 1% increments, with speed control from 20% to 100% and acceleration control from 1% to 100%. The grippers support up to 10,000 positioning points and can measure workpiece size in 0.01 mm increments.
Types and Models: Various models are available, including compact single cam, single cam, double cam, screw type (straight and "T" shape), and three fingers type. Each model has specific attributes such as gripping force, open/close stroke, maximum speed, and repeated positioning accuracy.
Key Features:
  • Adjustable gripping force for delicate workpieces like glass.
  • Workpiece presence detection without external sensors using the HOLD signal.
  • Speed and acceleration settings for gentle handling of sensitive components.
  • Multi-point position control for efficiency in mixed-material production lines.
Applications: The YRG series can be integrated with the iVY System for vision control, supporting applications like deformation prevention, chip assembly, and dimension checks for flexible workpieces.
Technical Details: Detailed specifications for each model include holding power, speed, repetitive positioning accuracy, and allowable load and moments. Installation guidelines ensure optimal performance and prevent damage.
Specifications: Models include YRG-2004T, YRG-2013T, YRG-2820T, and YRG-4230T, with specifications on holding power, open/close stroke, speed, and positioning accuracy. Designed for use with RCX240/RCX240S and RCX340 controllers, supporting up to 4 units.
Procedures: Installation and operation procedures stress securing the finger during bolt tightening to avoid excessive force on the guide block. The workpiece weight should be 1/10 to 1/20 of the holding power, with allowances for movement and swinging.
Norms and Recommendations: Recommendations include designing the finger to be short and lightweight, setting parameters to avoid excessive shock, and ensuring cables are securely fixed to prevent movement. Formulas for calculating load and moment based on external forces and distances are provided.
Graphical Data: Graphs illustrate the relationship between gripping power and gripping power settings, showing variations in actual gripping power.
Accessories and Options: Standard accessories include gripper control boards, robot cables, relay cables, and connectors for power supply and emergency stop, with specific models and lengths provided.
