Abstract: A lens clamping device (1), relating to the field of optical communication devices, comprises: a base (2); a sliding mechanism (3) slidably connected with the base (2) and movable relative to the base along a first direction; a transmission mechanism (4) connected with the sliding mechanism and having a first (41) and a second clamping member (42) capable of relatively away from and close to each other along a second direction perpendicular to the first direction; and a suction nozzle (5) fixedly connected to one end of the sliding mechanism along the first direction and used for sucking a lens; wherein the suction nozzle is between the first and second clamping member which are relatively close to each other to limit the displacement of the lens in the second direction. The lens clamping device improves the reliability of picking up the lens by means of limit in two directions.

Abstract: Device and method are provided to align and bond a lens array to a PD array with high precision, which can implement aligning and bonding of the lens array automatically. A telescopic rod of the stepping actuator is adjusted until photosensitive areas of the PD array form a clear image on the image acquisition CCD through the lens array, an adjusted distance h1 of the telescopic rod is recorded, and a position coordinate (xn, yn) of center of each circular photosensitive area in the image may be obtained, and a slope k1 of a line connecting the centers of the photosensitive areas is calculated. The telescopic rod is adjusted again, and a slope k2 of a line connecting the centers of the apertures of the lens array is calculated. Based on calculated values ?xn, ?yn, arctan(k1)?arctan(k2), the high-resolution adjustment stage is adjusted to adjust position of the lens array.
