Abstract
The utility model discloses a camera lens. The camera lens comprises a lens assembly and a substrate assembly; the lens assembly comprises a lens, a lens cone for accommodating the lens, and a light filtering sheet which is arranged at an end portion of the lens cone; the substrate assembly includes a circuit board and sensor which is arranged on the circuit board and is used for receiving light from the lens; the sensor is welded on the circuit board through adopting SMT technology; two opposite angle positions of a sensor welding area on the circuit board are respectively provided with a MARK point; and the MARK points are used for positioning the sensor. With the camera lens of the utility model adopted, imaging quality can be improved.
Description
Technical field
The utility model relates to optical pick-up apparatus, especially relates to a kind of pick-up lens.
Background technology
In prior art, in the production run of pick-up lens, need to sensor be welded on circuit board with SMT (surface mounting technology), pick-up lens requires the center of the strict alignment optical lens in center of sensor to guarantee image quality, permissible variation approximately 50 μ m, but the ratio of precision of SMT is lower, and on circuit board, there is no reference point, so cannot guarantee the precision of the welding position of sensor when SMT produces.
Along with development and the application of pick-up lens, people are more and more higher for the requirement of image quality, and therefore, the positional precision that improves sensor becomes pick-up lens and produces the major issue facing.
Utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that prior art scheme is improved and improved, and a kind of pick-up lens is provided, and its center sensor is strictly aimed at optical lens center, to reach the object that improves image quality.For this reason, the utility model is taked following technical scheme.
A kind of pick-up lens, comprise lens assembly and board unit, described lens assembly comprises eyeglass, hold the lens barrel of described eyeglass and be arranged on the optical filter of described lens barrel end, described board unit comprises circuit board and is arranged on described circuit board for receiving the sensor from described eyeglass light, described sensor is welded on described circuit board by the technology of SMT, and: on described circuit board, two diagonal positions of described sensor welding region are respectively arranged with a MARK point, and described MARK point is used for locating described sensor.
As the preferred technical scheme of one, described MARK point is that the mode of revealing copper is added on described circuit board.
As the preferred technical scheme of one, what described MARK was ordered is shaped as " L " shape, and width is not more than 50 μ m.
Owing to adopting technique scheme, the pick-up lens that the utility model provides has advantages of the image quality of raising.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model pick-up lens.
Fig. 2 is the schematic diagram of the circuit board of the utility model pick-up lens.
In figure, lens assembly 1, eyeglass 11, lens barrel 12, optical filter 13, board unit 2, circuit board 21, sensor welding region 211, MARK point 212, sensor 22.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, shown in Fig. 2, the utility model has disclosed a kind of pick-up lens, comprise lens assembly 1 and board unit 2, lens assembly 1 comprises eyeglass 11, hold the lens barrel 12 of eyeglass 11 and the optical filter 13 of lens barrel 12 ends, board unit 2 comprises circuit board 21 and is arranged on circuit board 21 for receiving the sensor 22 from eyeglass 11 light, the technology of sensor 22 use SMT is welded on circuit board 21, and: on circuit board 21, two diagonal positions of sensor welding region 211 are respectively arranged with a MARK point 212, MARK point 212 is for alignment sensor 22, in the time that SMT produces, can guarantee sensor 22 to be welded to sensor welding region 211, there is the image quality of raising.
As the preferred technical scheme of one, MARK point 212 is that the mode of revealing copper is added on circuit board 21, reveals process for copper simple, only the copper of this position on circuit board 21 need to be exposed, and does not need to apply protective paint.
As the preferred technical scheme of one, MARK point 212 be shaped as " L " shape, width is 50 μ m, 50 μ m are the ultimate range that allows sensor 22 misalignment eyeglass 11 centers, if the welding position deviation of sensor 22 exceeds 50 μ m, the edge that MARK is ordered can not expose, and easily judges SMT production precision.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
