Abstract
The utility model discloses an aperture location device used in the fingerprint identification module, which comprises an aperture and a lens, the aperture is provided with location columns which is connected with the aperture as a whole, the location columns are connected as a whole by two cylinders of different sizes, and the diameter of the lower end surface is bigger than the diameter of the upper end surface; the corresponding position of the lens is provided with the fixing holes, the size of which are matched with the size of the upper surface of the location column. The utility model ensures the coincidence of the aperture and the lens center, and eliminates the secondary errors.
Description
Technical field
The utility model relates to a kind of aperture locating device, relates in particular to a kind of aperture locating device that is used for fingerprint identification module.
Background technology
In the prior art, aperture and lens independently are installed in respectively in the fingerprint module housing, because the fingerprint module housing all is a working of plastics, precision own is not high, causes the offset problem of error, particularly optical axis center easily.
Summary of the invention
Technical problem to be solved in the utility model be overcome deficiency of the prior art and provide a kind of guarantee aperture and lens concentricity be used for the aperture locating device.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the aperture locating device of fingerprint identification module, comprise aperture and lens, it is characterized in that: described aperture is provided with the reference column that fuses with it, described reference column is fused by two right cylinders that vary in size, the lower surface diameter has the fixed orifice with reference column upper surface size coupling greater than the upper surface diameter on the relevant position of described lens.
Reference column described in the utility model has 4, is separately positioned on four drift angles of aperture.
The utility model compared with prior art has following beneficial effect: the center that has guaranteed aperture and lens overlaps, and eliminates two utmost point errors.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a right view of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, be respectively arranged with a reference column 3 that fuses with aperture on four drift angles of aperture 1, described reference column 3 is fused by two right cylinders that vary in size, and the lower surface diameter is greater than the upper surface diameter.Have 4 fixed orifices 4 that mate with reference column 3 upper surfaces size on the relevant position of lens 2, described reference column 3 inserts in the described fixed orifice 4, and aperture 1 and lens 2 are fixed together, and guarantees that the center of aperture and lens overlaps, and has eliminated two utmost point errors.
Claims (2)
