Lens coupling fixture based on voice coil motor driving

Abstract

The invention provides a lens coupling fixture based on voice coil motor driving. The fixture comprises a lens feeding assembly and a lens fixture assembly, the lens feeding assembly sequentially feeds lenses, and the lens fixture assembly clamps the fed lenses and moves the lenses to corresponding coupling positions for coupling; the lens fixture assembly comprises a multi-dimensional motion platform and a lens fixture arranged on the multi-dimensional motion platform, the lens fixture is mainly composed of a fixture base fixedly arranged on the multi-dimensional motion platform, two guide rails arranged on the fixture base in parallel, two connecting parts with the first ends arranged on the two guide rails in a sliding mode respectively, and lens chucks fixedly arranged at the second ends of the two connecting parts respectively, and the connecting parts are driven by two voice coil motors arranged on the fixture base respectively. The lens clamp is driven by the voice coil motors,has the characteristics of being simple in structure, small in size and fast in response, is suitable for miniaturized lens fixtures, and effectively improves the coupling precision and packaging quality of the lenses.

Description

technical field [0001] The invention relates to the technical field of automatic coupling and packaging of optical devices, in particular to a lens coupling fixture driven by a voice coil motor. Background technique [0002] With the development of optical fiber communication and optical fiber sensing technology, the preparation of optical devices has become the key to the progress of optical information technology. In optical communication products, the demand for light-emitting components is increasing, and its function is mainly to realize the photoelectric conversion of signals. A common light-emitting element is mainly composed of a substrate + a light-emitting chip + a lens. One of the packaging and manufacturing processes is to couple the micro-lens to the light-emitting chip, and then complete the packaging by dispensing and curing. How to improve the performance and quality of optical devices and reduce costs is the key issue in current packaging and manufacturing ...

AI Technical Summary

Problems solved by technology

Therefore, the accuracy of lens coupling significantly affects the packaging quality of the above-mentioned light-emitting elements. Since the lens is generally a micro-lens with a size of less than 1 mm, the storage, loading, and coupling processes are more sophisticated and complicated, and it is difficult to meet the requirements of the conventional coupling fixture. Packaging accuracy requirements, and production efficiency is not high
