Abstract
The invention provides an auxiliary device for measuring eccentric quantity. The auxiliary device is used for auxiliary measurement on the eccentric quantity of a piece of eyeglass to be measured; the eyeglass to be measured comprises an optical part and a non-optical part that is surround the optical part; the optical part comprises an optical curved surface and an optical plane that are arranged back to back with each other; the non-optical part comprises a first positioning part that surrounds the optical plane and is coaxial to the optical plane; the auxiliary device for measuring the eccentric quantity comprises a caky body and an arch bulge arranged on the body; the arch bulge is coaxial to the body; a reference curved surface used for auxiliary measurement on the eccentric quantity of the eyeglass to be measured is arranged on the surface at the external side of the arch bulge; and a second positioning part matched with the first positioning part is arranged at the periphery of the body. The auxiliary device for measuring the eccentric quantity of the eyeglass to be measured can be used for measuring the eccentric quantity of the curved surface relative to the reference curved surface by the eccentricity measuring device after the first positioning part and the second positioning part are clamped mutually, thus obtaining the coaxiality of the curved surface and the first positioning part.
Description
Technical field
The present invention relates to a kind of measurement offset servicing unit.
Background technology
The camera lens module generally comprises a plurality of optic with optical effect and forms around the eyeglass of the non-optical division of this optic, the non-optical division of each eyeglass generally all comprises a location division coaxial with this optic, and these a plurality of eyeglasses engage the accurate location of realizing between eyeglass mutually by this location division.At present in the camera lens module the optic of first eyeglass of close object generally include a curved surface and a plane back to this curved surface towards object, and this position point is in this plane one side.
In order to adapt to production in enormous quantities, eyeglass generally forms by the mould model.For this first eyeglass, because this plane and location division are positioned at relative both sides with this curved surface, injection molded after therefore need cooperatively interacting by public affairs and master mold, yet, because the accurate positioning degree of male model and master mold is limited at present, the right alignment of this curved surface and this location division is difficult to guarantee.Therefore, in allowed limits whether off-centre or offset need to detect the curved surface of the eyeglass by mould model and plane.Yet, because offset is the side-play amount of the relative optical axis of line of two curved surface focuses, so present eccentric measuring set can't directly be measured the offset of curved surface opposite planar.
Summary of the invention
In view of this, be necessary to provide a kind of measurement offset servicing unit.
A kind of measurement offset servicing unit, it is used for the offset of subsidiary eyeglass to be measured, and this eyeglass to be measured comprises an optic and the non-optical division around this optic.This optic comprise mutually back to an optical surface and an optical flat, this non-optical division comprises one around this optical flat and first location division coaxial with this optical flat.This measurement offset servicing unit comprises body and arch projection of a pie.This body comprise mutually back to an end face and a bottom surface.This arch projection vertically stretches out from this end face and forms a reference curved surface that is used for the offset of subsidiary eyeglass to be measured, outer the placing of this bottom surface offers second location division that is complementary with this first location division, and this is coaxial with this second location division with reference to curved surface.
This eyeglass to be measured is with after this measurement offset servicing unit engages mutually by first and second location division, can measure this optical surface by eccentric measuring set relatively should be with reference to the offset of curved surface, thereby draws the optical surface of this eyeglass to be measured and the offset of this optical flat.

Embodiment
Please refer to Fig. 1, the eyeglass to be measured 20 of 10 subsidiaries of measurement offset servicing unit of better embodiment of the present invention comprises an optic 22 and the non-optical division 24 around optic 22.Optic 22 comprises an optical surface 22a and the optical flat 22b back to optical surface 22a.Non-optical division 24 comprises one around optical flat 22b and the first location division 24a coaxial with optical flat 22b, and in the present embodiment, the first location division 24a is from the vertical outward extending annulus projection of optical flat 22b.
When testing, will measure offset servicing unit 10 and be arranged on the eyeglass 20 to be measured, and make that bottom surface 12b and optical flat 22b are accurate to fit, simultaneously with reference to curved surface 14a away from optical flat 22b.Because mate mutually the first location division 24a and second location division 16, make that measuring offset servicing unit 10 accurately is arranged on the eyeglass 20 to be measured, and it is accurately coaxial with the first location division 24a to measure offset servicing unit 10.At this moment, on optical surface 22a that the probe 30 of eccentric measuring set is supported at eyeglass 20 to be measured and the reference curved surface 14a that measures offset servicing unit 10, just can measure the offset of optical surface 22a relative reference curved surface 14a, thereby obtain the right alignment of the optical surface 22a and the first location division 24a of eyeglass 20 to be measured.
Be appreciated that, the setting of the first location division 24a and second location division 16 is accurately coaxial with second location division 16 in order to make with reference to curved surface 14a after making measurement offset servicing unit 10 be arranged on the eyeglass 20 to be measured, yet the set-up mode of the first location division 24a and second location division 16 is not limited to present embodiment.
Those skilled in the art will be appreciated that; above embodiment only is to be used for illustrating the present invention; and be not to be used as limitation of the invention; as long as within connotation scope of the present invention, appropriate change and the variation that above embodiment did all dropped within the scope of protection of present invention.
