Abstract
The utility model discloses a kind of camera lens bearing fixture, comprise breasting part, locating part, seal; Locating part is located at the breasting part back side; Breasting part front is provided with groove; Seal is located in groove, and seals with breasting part and be connected; Some through holes are provided with in the groove of breasting part; Position corresponding with through hole on locating part is provided with spacing hole; Breasting part is provided with suction hole; Suction hole is connected with the groove of breasting part.The utility model camera lens bearing fixture is applicable to the camera lens of various external form, and all can carry out MTF test under being greater than the prerequisite of 0.45mm to Jiao after sensor mechanism.
Description
Technical field
The utility model relates to a kind of bearing fixture for testing lens mtf value.
Background technology
Because of the demand of market ultrathin, the preposition camera lens demand TTL(optics overall length of notebook computer) shorter and shorter, after corresponding mechanism, burnt (FBL) is also just limited in about 0.5-0.55mm.Existing camera lens has following two kinds of breasting modes on bearing fixture: 1, top breasting; 2, bottom breasting.
Above two kinds of breasting modes all have shortcoming.Top breasting type, as shown in Figure 1, needs camera lens exterior design to become large petal, but the camera lens external form of small-flowered for some customer requirement, then cannot realize the detection to its camera lens mtf value (vertical projection).Bottom breasting type, as shown in Figure 2, then after requiring mechanism, Jiao is very long.
For DSC-501R, because of bearing fixture and sensor(light sensation coupling element) restriction burnt after mechanism, as shown in Figure 3,4,0.65mm can only be greater than to Jiao after mechanism, or external form be large petal, the camera lens of top breasting type carries out mtf value detection.
Summary of the invention
The purpose of this utility model is to solve the defect existed in prior art, provides a kind of and carries out the detection of camera lens mtf value, bearing fixture to appearance structure no requirement (NR).
In order to achieve the above object, the utility model provides a kind of camera lens bearing fixture, comprises breasting part, locating part, seal; Locating part is located at the breasting part back side; Breasting part front is provided with groove; Seal is located in groove, and seals with breasting part and be connected; Some through holes are provided with in the groove of breasting part; Position corresponding with through hole on locating part is provided with spacing hole; Breasting part is provided with suction hole; Suction hole is connected with the groove of breasting part.
Further improvement of the utility model is: breasting part is provided with leveling serew.This leveling serew is provided with three, is triangular in shapely distributed on breasting part.
Wherein, seal adopts glass.
The utility model has the following advantages compared to existing technology: the utility model carries out breasting by breasting part to camera lens, and produce vacuum carry out whole dish camera lens absorption; Utilize locating part to the modulation of spacing hole aperture size simultaneously, thus for the measurement of different size product.Whether the utility model adopts glass as seal, effectively can observe testing product and be adsorbed; Utilize leveling serew to adjust levelness, effectively can guarantee the accuracy measured.The utility model camera lens bearing fixture is applicable to the camera lens of various external form, and all can carry out MTF test under being greater than the prerequisite of 0.45mm to Jiao after sensor mechanism.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 4, DSC-501R type bearing fixture, before improvement, is made up of panel 4, glass 5 and base plate 3, can only to >0.65mm burnt after sensor mechanism, or the product of the camera lens top portion breasting of large petal detects.
The utility model camera lens bearing fixture improves it, composition graphs 5 to 8, comprises breasting part 6, locating part 7, seal 8, leveling serew 9.Seal 8 adopts seal glass.Locating part 7 is located at breasting part 6 back side.Breasting part 6 front is provided with groove 10.Seal 8 is located in groove 10, and seals with breasting part 6 and be connected.Be provided with some through holes 11 in the groove 10 of breasting part 6, position corresponding with through hole 11 on locating part 7 is provided with spacing hole 13.Breasting part 6 is provided with suction hole 12, and suction hole 12 is connected with the groove 10 of breasting part 6.Breasting part 6 edge is that equilateral triangle is provided with three leveling holes, and leveling serew 9 is located in leveling hole, carries out Level-adjusting by leveling serew 9.
The principle of work of the utility model camera lens bearing fixture is: after utilizing seal 8 to seal, and produces airtight die cavity, make to produce vacuum in die cavity by suction hole 12 in the groove 10 of breasting part 6.Pull of vacuum is delivered to spacing hole 13 place of locating part 7 by the through hole 11 of breasting part 6, and cooperation group vertical plate is by PPL(angle scale) turn to petal upwards, thus whole dish absorption is got up, carry out MTF test.
