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
Camera lens module generally comprises multiplely have been had the optics portion of optical effect and has formed around the eyeglass of the non-optical division in this optics portion, the non-optical division of each eyeglass generally comprises a location division coaxial with this optics portion, and the plurality of eyeglass is mutually engaged by this location division and realizes the accurate location between eyeglass.Generally include a curved surface towards object and a plane back to this curved surface near the optics portion of the first eyeglass of object in current camera lens module, and this position point is in this plane side.
In order to adapt to produce in enormous quantities, eyeglass is generally formed by 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 needing to be cooperatively interacted by public and master mold, but, because the positioning accurate accuracy of current male model and master mold is limited, the right alignment of this curved surface and this location division is difficult to ensure.Therefore, need to detect whether whether in allowed limits bias or offset by the curved surface of the eyeglass of mould model and plane.But, be the side-play amount of the relative optical axis of line of two curved surface focuses due to offset, so current eccentric measuring set directly cannot measure the offset of curved surface opposite planar.
Summary of the invention
In view of this, be necessary that providing a kind of measures offset servicing unit.
A kind of measurement offset servicing unit, it is for the offset of subsidiary eyeglass to be measured, and this eyeglass to be measured comprises an optics portion and a non-optical division around this optics portion.This optics portion 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 an arch projection of a pie.This body comprise mutually back to an end face and a bottom surface.This arch projection forms a reference surface for the offset of subsidiary eyeglass to be measured from this end face Vertical dimension extension, outer the placing of this bottom surface offers second location division matched with this first location division, and this reference surface is coaxial with this second location division.
After this eyeglass to be measured is engaged by first and second location division mutually with this measurement offset servicing unit, measure the offset of this optical surface this reference surface relative by eccentric measuring set, thus draw the optical surface of this eyeglass to be measured and the offset of this optical flat.
Accompanying drawing explanation
Fig. 1 is the structural representation that the measurement offset servicing unit of better embodiment of the present invention is arranged on eyeglass to be measured.

Embodiment
Please refer to Fig. 1, the eyeglass to be measured 20 of measurement offset servicing unit 10 subsidiaries of better embodiment of the present invention comprises an optics portion 22 and a non-optical division 24 around optics portion 22.Optics portion 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 protruding from the vertical outward extending annulus of optical flat 22b.
Measure body 12 and an arch projection 14 be formed on body 12 that offset servicing unit 10 comprises a pie.Body 12 comprise mutually back to an an end face 12a and bottom surface 12b, the outside of arch projection 14 forms one and is used for the offset of subsidiary eyeglass 20 to be measured with the interconnective reference surface 14a of described end face 12a, reference surface 14a.Outer the placing of the bottom surface 12b of body 12 offers second location division 16 matched with the first location division 24a.In the present embodiment, the second location division 16 is for being opened in the outer ring groove placed of bottom surface 12b.Reference surface 14a is coaxial with the second location division 16.Measure offset servicing unit 10 to be accurately combined with the second location division 16 by the first location division 24a with eyeglass 20 to be measured.In order to ensure the right alignment measuring offset servicing unit 10, precision cutting mode can be adopted to make and measure offset servicing unit 10, its material used can be the solid material such as metal or plastics.
When testing, be arranged on eyeglass 20 to be measured by measurement offset servicing unit 10, and bottom surface 12b and optical flat 22b precision is fitted, reference surface 14a is away from optical flat 22b simultaneously.Because the first location division 24a mates mutually with the second location division 16, make to measure offset servicing unit 10 and be accurately arranged on eyeglass 20 to be measured, and it is accurately coaxial with the first location division 24a to measure offset servicing unit 10.Now, the probe 30 of eccentric measuring set is supported on the optical surface 22a of eyeglass 20 to be measured and the reference surface 14a of measurement offset servicing unit 10, just the offset of optical surface 22a relative reference curved surface 14a be can measure, thus the optical surface 22a of eyeglass 20 to be measured and the right alignment of the first location division 24a obtained.
Be appreciated that, the setting of the first location division 24a and the second location division 16 reference surface 14a can be made accurately coaxial with the second location division 16 in order to make measurement offset servicing unit 10 be arranged on after on eyeglass 20 to be measured, but the set-up mode of the first location division 24a and the second location division 16 is not limited to present embodiment.
Those skilled in the art will be appreciated that; above embodiment is only used to the present invention is described; and be not used as limitation of the invention; as long as within spirit of the present invention, the suitable change do above embodiment and change all drop within the scope of protection of present invention.
