Technical field

The utility model relates to and a kind ofly piles up the optical glass lens array and pile up camera lens module, especially refer at least two optical glass lens arrays of a kind of utilization, earlier after aligning its optical centre axle again with adhesive glassine tank in set viscose glue stacked combination and the precision combination of making pile up the optical glass lens array, utilize the described optical glass lens array that piles up to become the single optical mirror slip element that piles up again with the detent mechanism cutting and separating, cooperate required optical element to install again and pile up camera lens module, for the combined lens that is used in led light source to form in the lens bracket, the combined lens of solar-energy conversion systems, and the optical frames of mobile phone camera is first-class.

Background technology

Precision glass molding moulding (glass precision molding) technology has been widely used in the manufacturing high-res, the aspheric surface modeling glass lens of the good and lower cost of stability, as U.S. Pat 2006/0107695, US2007/0043463, Taiwan patent TW095101830, TW095133807, Jap.P. JP63-295448 etc., it is to utilize the characteristic of glass at hot mastication, with glass unit material (or glass preform, glass preform) last, thermoplastic in the bed die, to go up again, the corresponding closure of bed die is also exerted pressure, make, the optics die face of bed die is transferred on the softening glass preform, separates after cooling off, bed die take out and become one have on, the modeling glass lens of bed die die face.And be to reduce manufacturing cost, Jap.P. JP63-304201, U.S. Pat 2005/041215 propose the lens array (lens array) of glass mould model; For making single eyeglass, be called lens element (lens element) at this, Jap.P. JP02-044033 propose to use mobile glass material further to cut into a plurality of lens elements in model mode repeatedly again to make the Optical blanks with a plurality of optical mirror slips.

The optical mirror slip of glass mould model has begun to apply in a large number combined lens, and the optical lens of mobile phone camera of combined lens, the solar-energy conversion systems of led light source; Combined lens or optical lens are the optical imagery effect, often need be combined into the optical mirror slip module with certain airspace with the different dioptric optical mirror slips of multi-disc.Therefore, when the different dioptric optical mirror slips of multi-disc make up, the optical centre axle of each optical mirror slip (optical axis) needs the accurate problem that aligns to avoid resolution to reduce, and each optical mirror slip also need combine with certain spacing, so will expend many operations and fine adjustment, causing output can't improve, and cost also is difficult to descend; Especially on the optical mirror slip array combination, when the optical centre axle of optical mirror slip array produces skew, will influence optical effect, thus more complicated and important on the optical mirror slip array calibration.On the optical mirror slip array is made, the manufacture method of plastic cement optical mirror slip array is proposed as Jap.P. JP2001194508; Taiwan patent TW M343166 proposes glass optics manufacturing method of lens arrays.After making, the optical mirror slip array can cutting and separating become single optical mirror slip unit, to be assembled in the camera lens module (lens module).Perhaps can earlier optical mirror slip array and other optical elements (opticalelement) be combined into camera lens secondary module array (lenss ubmodule array) earlier, cut into single camera lens secondary module (lens submodule) again, through with lens bracket (lens holder), image sensor (image capture device) or other optical element combination after, make camera lens module (lens module).

On the camera lens module array is made, U.S. Pat 7,183,643, US2007/0070511, WIPO patent WO2008011003 etc. propose brilliant unit level camera lens modules (Wafer level lensmodule).As Fig. 1, the camera lens module array that general optics is used comprises a diaphragm 711 (aperture), a watch glass 712 (cover glass), multi-disc optical mirror slip and an infrared ray filter glass 717 (IR cut lens) usually, as shown be three-chip type optical mirror slip group, comprise first optical mirror slip 714 (first lens), second optical mirror slip 715 (second lens) and the 3rd optical mirror slip 716 (third lens), separate with distance piece 713 (spacer) between each optical mirror slip; After making up, form a camera lens module array, after cutting, make camera lens module.WO2008/063528 makes camera lens module with stack manner for another the WIPO patent, as Fig. 2, with diaphragm 711, first optical mirror slip 714, distance piece 713, second optical mirror slip 715, distance piece 713, the 3rd optical mirror slip 716, image sensor 717, circuit board 718, encapsulation (packing) constitutes a camera lens module in packaging body (encapsulant) 719.

Yet, for the camera lens module array, when multi-disc optical mirror slip array combination, each optical mirror slip array align the resolution that (alignment) will influence the camera lens module array, in the combination of multi-disc optical mirror slip array, U.S. Pat 2006/0249859 proposes to use infrared ray (infraredray) to produce reference point label (fiducial marks) to make up brilliant unit level eyeglass module; In the combination of plastic cement optical mirror slip array, the open biconvex optical mirror slip array of Jap.P. JP2000-321526, JP2000-227505 is with the method for projection (height) with recessed crack (crevice) combination; U.S. Pat 7,187,501 propose to utilize cone (cone-shaped projection) to pile up the plastic cement optical mirror slip array of (stack) multi-disc.Yet,, often formed by multiple difform optical mirror slip array at the optical mirror slip module array that the optical lens of the combined lens of the combined lens of led light source, solar-energy conversion systems and mobile phone camera uses.In the method that existing plastic cement optical mirror slip array makes up with teat (projection) and depression (hole), because plastic cement optical mirror slip array is with plastic jetting forming, can cause material contracts and size is changed at projection and place, recessed crack, its bearing accuracy is difficult to improve, cause the difficult location of optical centre axle, suitable restriction is arranged in the use.Moulded glass is made eyeglass, and its refractive index ratio plastic cement is good, and can be heat-resisting, gradually is applied in the various optical systems; Because the optical mirror slip array that moulded glass is made, its contraction problem is less relatively, therefore develop optical glass lens module array simple and easy and that precision is high, offer combined lens, the solar-energy conversion systems of led light source combined lens, and the optical lens of mobile phone camera use, just can meet the yield of mass production and the demand of mass production.
