EINA has found an automation solution for a range of tasks which couldn´t be carried out without the help of Men's eyes and / or hands. |
||
Some examples of those operations are:
|
 |
|
| Those tasks have a high cost, not only because of the cost on time and money of the specialised workers, but also on quality. | ||
Previous attemps of automation have failed because of 3 mean reasons:
In consecuence, those parts have huge dimensional tolerances, they easily bend. and it is extremly hard to always fix them them in the same position. |
||
A Solution could be to manufacture huge and complicated fixtures which would completely fix the position of the part; and then program a robot or PLC in a Standard way (every single trajectory) Those solutions cannot be afforded, not only because of financial reasons, but also because of operational reasons. |

EINA has copied the human behaviour to develop a tracking tool, which is able to track a surface without previous programming, either applying a constant force to the tracked surface, either keeping an offset to the tracked surface.
The video shows how a robot, through the sensors in the tracking head, remains perpendicular to a certain surface whatever surface it is.
The man changes the surface's orientation, and the robot changes its axis configuration in order to maintain perpendicularity. |
The mechanical flexibility of the offline tracking tool permits the ADAPTATION of the polishers (or any other kind of device) to the surface.
The position polishers take is detected by the laser sensor and the pressure sensor. According to this position, the robot modifies its axis configuratioon until it achieves a parallel position with the surface to polish
