Abstract
The lens used in optic communication device and fibre optical sensor are gradually miniaturized, and existing traditional optical manufacturing can not meet to require.The lapping device of the utility model micro lens, a kind of Moveable-jacket tubular construction is invented, part to be processed is fixed using the inner sleeve of axial pressure, under the pressure of flexible member, it can be slided between inner sleeve and outer tube, the end face of outer tube, inner sleeve and work piece contacts with grinding the cavity plate face of rotary disk simultaneously, and outer tube also serves while increase is ground and coordinates area to repair a die, and can process diameter as low as 0.2mm thin cylindrical lens CLENS sphere.The utility model device, solve the problems, such as material cutting output difference during different hardness material simultaneous grinding, obtain good part spherical surface type.
Description
Technical field
The present invention relates to a kind of lapping device of micro-optical sphere, belong to optical manufacturing field.
Background technology
With optic communication and the development of optical fiber sensing technology, the lens in optic communication device and fibre optical sensor are gradually miniature
Change, now traditional processing can not meet that producing diameter such as is less than 0.5mm micro- spherical lens.
The content of the invention
The lens used in optic communication device and fibre optical sensor are gradually miniaturized, and are less than 0.5mm if desired for processing diameter
Micro- spherical lens CLENS, existing traditional optical manufacturing can not meet to require.
The present invention relates to a kind of lapping device of micro-optical sphere, difference is to have invented a kind of removable sleeve pipe
Structure, part to be processed is fixed using the inner sleeve of axial pressure, outer tube also rises while increase is ground and coordinates area and repaiied
Mould acts on, and this method can process the sphere of diameter as low as 0.2mm thin cylindrical lens.
Concrete scheme is：Including upper cover, never-slip and grinding rotary disk, upper cover is used to fixed sleeving fixture and swung apply
Pressure, swinging pressure can be realized by stylus, and grinding rotary disk provides axial gyration, has the polishing of advance reconditioning recessed on disk
Mould, recessed mill are made up of fixed abrasive material, and never-slip includes outer tube, inner sleeve, the flexible member of axial pressure, look nut,
Processed thin cylindrical lens are fixed in inner sleeve, can be with the pressure of flexible member, between inner sleeve and outer tube
Slide, the end face of outer tube, inner sleeve and work piece contacts with grinding the cavity plate face of rotary disk simultaneously.
Inner sleeve in the present invention, the material as similar in the hardness of processed glass are made, and inner sleeve is with being processed
Fixed between glass with media such as paraffin, glue it is integral, by expanding overall burnishing surface to obtain good piece surface face type, this
Outer tube in invention, it is made up of the material higher than the hardness of processed glass, outer tube is ground in increase coordinates area
Also serve simultaneously and repair a die.Inner sleeve, the outer sleeve structure that can be slided relatively in the present invention, solve different hardness material simultaneously
During grinding the problem of material cutting output difference, good spherical surface type is obtained.The thin rod of lens of sphere is processed, can after dispergation
Taken out from inner sleeve, be further continued for cutting, grind, polish other end, lens finished product is made.
Brief description of the drawings
The schematic diagram of the embodiment of the present invention.
Embodiment
Embodiments of the invention are further described below in conjunction with accompanying drawing.
Including upper cover (1), never-slip (2), grinding rotary disk (3), there is stylus cavity plate (11) above upper cover (1), lead to
Cross stylus and downward pressure and swing are provided, never-slip (2) includes outer tube (21), inner sleeve (22), spring (24), pressure regulation
Nut (25), be processed lens (23) fixed with inner sleeve (22) with glue it is integral, in look nut (25) and spring (24)
Under pressure, it is processed lens (23) and can be slided with inner sleeve (22) in outer tube (21), the polishing on grinding rotary disk (3) is recessed
Mould (31) is made up of fixed abrasive material, and grinding rotary disk (3) provides gyration, drives never-slip (2) in polishing cavity plate (31)
Interior rotation, polishing cavity plate (31) is interior can to add water or polishing fluid, while polishes outer tube (21), inner sleeve (22) and processed lens
(23).The processed lens (23) of sphere are processed, can be taken out after dispergation from inner sleeve (22).
