End-of-Arm Tooling Adapter Plate

Backlash originating at the robot-to-tool interface reduces path precision, especially in force-sensitive processes such as automated fastening, ultrasonic welding, or adhesive dispensing. Adapter plates are manufactured with matched dowel pin locations and transition-fit bore tolerances (H7/g6), eliminating micro-slippage. Surface flatness of the mating face is maintained within 2 microns to ensure rigid contact across the entire interface plane, and secondary locking features—such as serrated face patterns or eccentric pins—are integrated to resist loosening under cyclical loading. 

Frequent reconfiguration of EOAT setups in flexible robotic cells often necessitates full TCP recalibration, resulting in machine downtime and process variability. Adapter plates are designed to support repeatable modular tool changes via integrated kinematic couplings or mechanical zero-point referencing. When used with tool changers, the design maintains axial registration and angular orientation within ±0.02 mm and ±0.03°, respectively, removing the need for iterative calibration procedures after each tooling swap.
