New assembly technique |
New
robotized assembly technique.
|
The high-precision assembly technique used to assemble our system is based
on a new low-cost patented optical holder, which was developed at the Institut de Systèmes Robotiques in |
|
These holder possess three hemispherical feet, which are bent to remain in contact with the base. Once the optical element is perfectly aligned, thanks to a high precision robot, the three feet are welded simultaneously by three laser beams. |
|
a) The robot arm grips the holder |
b) The optics is aligned accurately thanks to the precision of the robot arm. The three feet are deformed to remain in contact with the base. |
|
c) Three laser beams weld simultaneously the feet of the holder to the base. |
d) The robot arm releases the holder. |
