Fabrication and alignment device
View Patent ↗A system for actively aligning an optoelectronic device including a frame, a mounting and alignment assembly, and a camera. The mounting and alignment assembly can be movably connected to the frame and is configured to mount separate portions of an optoelectronic device such that the portions can be moved in relation to each other. An optical signal from a laser in the first portion is transmitted through an optical element in the second portion and captured by the camera to determine the positioning of the first and second portions of the optoelectronic device. The portions can then be aligned accordingly.
1. A system for optically aligning two portions of an optoelectronic device, a first portion containing a laser and a second portion containing an optical element, the system comprising:
a frame;
a mounting and alignment assembly attached to the frame, comprising:
a first mount at least indirectly attached to the frame and configured to removably retain the first portion of the optoelectronic device;
a second mount at least indirectly attached to the frame and configured to removably retain the second portion of the optoelectronic device; and
means for moving at least one of the first mount and second mount in relation to the frame in at least one dimension so that the first portion and the second portion of the optoelectronic device are situated such that the laser can optically couple with the optical element; and
camera mounted on the frame, the camera comprising a lens configured to be disposed in the optical path of the laser for imaging an optical signal emitted from the laser.
2. The system as recited in claim 1 , wherein the lens of the camera is configured to enlarge the optical signal emitted from the laser.
3. The system as recited in claim 1 , wherein the image produced by the camera includes a target which indicates the desired tolerance range of alignment.
4. The system as recited in claim 1 , wherein means for moving at least one of the first mount and second mount in relation to the frame in at least one dimension comprises a base connected to the frame, wherein at least one of the first mount and the second mount is disposed on the base.
5. The system as recited in claim 4 , further comprising a threaded rod disposed through the first mount or second mount that is disposed on the base and a wheel connected to the threaded rod.
6. The system as recited in claim 1 , wherein means for moving at least one of the first mount and second mount in relation to the frame in at least one dimension comprises a carriage slidably connected to the frame, wherein one of the first mount and the second mount is connected to the carriage.
7. The system as recited in claim 1 , wherein the camera is configured to move in relation to the frame in at least one dimension.
8. The system as recited in claim 7 , wherein further comprising a pneumatic cylinder having a first end connected to the frame and a second end connected to the camera.
9. The system as recited in claim 1 , further comprising a projection welding electrode for welding together the first portion and the second portion of the optoelectronic device.
