Robotised island for the certification of measurement samples
Study of an automated certification system for precision blocks used as calibration sample for numerical control machines/tools.
PROJECT NEEDS AND SPECIFICATIONS
Operation carried out manually in the certified laboratories through the comparison with standard reference samples.The manual operation involves problems of manipulation and preservation of the non-specific conditions imposed by the standard (Machinery Directive 2004/48): Temperature of 25°C, absence of vibrations, etc.
Design and development of the PLC/PC interface
Analysis and simulations
Robot testing and control – work areas
Dimensioning and design of the Cartesian handling system
Precision and handling tests
Use of an anthropomorphic robot to carry out the movement of the pieces from the various worktops and a Cartesian axis system, which speeds up and simplifies the robot cycle, reducing as much as possible measurement errors due to the broader movements using picking robots.
The new system fulfils the need to carry out the calibration and certification of blocks in the shortest possible time by eliminating manual and repetitive procedures with a high risk of error.The desired tolerances also impose a temperature control of the piece measuring chamber.
The system certifies the size of steel or ceramic specimens used in machine tool calibration.
A camera, placed above the tray, can read the identification code of each specimen, therefore check its presence and nominal size.
