- The robot has been equipped
with
- two length gauges
(1µm) for:
- improving the accuracy on
the origin of the charriot movement;
- measuring the transverse
displacements of the charriot;
- An optical system for
visual inspection of the position of the module has been bought
- Vacuum Chuck:
after some experience with the CPPM
vaccum chuck ( with this device the module was kept
by vacuum with a force of 25g applied on the module border, the same measurement
on a glass piece is 70g) we designed a chuck compatible with Module 4 and Module
5 and with enough room for the pigtail in order to minimize the repulsive
force; the chuck will be checked on the next week;
- Cradle:
the actual bar shows a sagitta smaller than 100µm
without any constraints and around 30µm when mounted on the robot charriot.
A new drawing for having support and protection of pigtails is ready:
