Lens coupling equipment driven by voice coil motor

Abstract

The invention provides lens coupling equipment driven by a voice coil motor. The lens coupling equipment comprises a lens feeding assembly, a lens clamping assembly, an optical device fixing table, acoupling detection assembly and a visual detection assembly, wherein a plurality of lenses are pre-installed in the lens feeding assembly, and are fed in sequence; the lens clamping assembly is used for clamping and moving the lenses fed by the lens feeding assembly to a corresponding packaging position on the optical device fixing table to be coupled with a light-emitting chip of a light-emittingelement fixed to the optical device fixing table; and the coupling detection assembly is used for confirming the coupling precision of the lenses and the light-emitting chip through light spot detection. A lens clamp of the lens clamping assembly is driven by the voice coil motor, has the characteristics of being simple in structure, small in size and fast in response, is suitable for a clamp ofminiaturized lenses, can control clamping force with high precision, and improves clamping and coupling precision 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 device 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 i...

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
