An automated optical chip holder for use in a pigtailing system precisely positions an optical chip at a predetermined location in three-dimensional space to align the optical chip within the pigtailing system. An adjustable chuck assembly is driven by a stepper motor under PLC control to position optical chip. After alignment, the optical chip is clamped by the adjustable chuck assembly during the pigtailing process to prevent the optical chip from moving out of alignment. This significantly reduces the occurrence of glue-joint failure and misalignment due to retraction stress. The clamp is fabricated using soft resilient materials at the point of contact with the chip. Thus, uniform pressure is exerted on the chip, micro-vibrations are absorbed, damage to the chip is reduced, and the necessity of precision motion control of the chuck assembly is avoided. The design of the automated chip holder allows the optical chip to be loaded and the pigtailed chip to be automatically unloaded using minimal operator involvement. The automated chip holder also accomodates different sized optical chips without altering the size of the chuck assembly holding the device. <IMAGE> |
