Abstract

The present invention provides a lens clamping and coupling positioning device for multi-channel COB packaging, including: a mounting plate, a lens fixture, a three-dimensional motion platform, a monitoring device and a support column; the three-dimensional motion platform includes an X-direction slide table, Y-direction slide table and Z-direction slide table, the X-direction slide table, Y-direction slide table and Z-direction slide table are respectively driven by X-direction motor, Y-direction motor and Z-direction motor, and are used to drive the lens holder for coupling , the bottom of the front end of the lens fixture is provided with a clamping groove, the clamping groove is used to clamp the lens, the rear end of the lens is inserted with a pigtail, and the monitoring device can monitor the lens fixture and the lens in real time position; the invention has simple structure, convenient operation, high coupling precision and stable clamping characteristics, effectively solves the problems of low coupling precision and weak device clamping, improves product quality and reduces production cost.

Description

technical field [0001] The invention relates to COB packaging technology, in particular to a lens clamping and coupling positioning device for multi-channel COB packaging. Background technique [0002] COB (Chip-on-Board), also known as chip direct mounting technology, refers to the process of directly pasting the bare chip on the printed circuit board, then performing wire bonding, and then encapsulating and protecting the chip and leads with organic glue. . Compared with conventional technology, this technology has high packaging density and simple process. [0003] Lens (lens) is an important component widely used in the field of optical fiber communication. It is usually coupled and packaged with optical chips in the form of COB. The accuracy of coupling is crucial to the quality of product production; existing coupling methods usually use lenses The clamping device of the component performs active coupling, but the coupling accuracy of the existing clamping and coupli...
