2.3.3. Servo gun squeeze force – current table tuning
To squeeze the various servo guns installed on the robot with the desired squeeze force, it is necessary to make the current applied to the servo gun correspond to the generated squeeze force. For this, we provide a servo gun squeeze force – current table, and it is necessary to tune it to the servo gun. The level of tuning accuracy determines the accuracy of the servo gun squeeze force. Therefore, the relevant setting must be carried out prior to the use of the servo gun.
To use this function, five representative values should be selected from the squeeze force range that will be used. The tuning of the servo gun squeeze force – current table is a process of finding the current table that matches with the five representative values of squeeze force. This table can be changed according to the posture of the servo gun. Therefore, it is necessary to carry out tuning for the case in which the moving tip is in the direction of gravity and for the case in which it is in the opposite direction of gravity. That way, squeeze can be carried out with high accuracy with the servo gun at various postures.
We provide two different modes for servo gun squeeze force – current table tuning.
n Automode tuning
This is for automatically tuning the table using the squeeze force data sent from the communicable squeeze force gauge designated by the company.
n Manual mode tuning
It is possible to carry out tuning regardless of whether or not there is a communicable squeeze force gauge. The user can tune the table by directly inputting the measured squeeze force.
