Description
Technical field
The utility model relates to a kind of positioning mirror head bracket (Lens holder withalignment for Stacked lens module) that piles up camera lens module, especially refer to that a kind of to pile up the camera lens secondary module with one be that inserts utilization is imbedded inserts ejection formation or compression-moulding methods and had the camera lens module of positioning mirror head bracket with moulding one, use to be fit to camera lens, small-sized camera lens, mobile lens.
Background technology
Optical mirror slip (optical lens) is the minimum optical element of camera or the mobile lens of taking pictures, and can be made up of one or above optical mirror slip (optical lens) during use; As shown in Figure 1, optical mirror slip 20a makes with optics plastic cement or optical glass material, comprise: have the optical effect face optical surface (optical surface) 21a its be generally circular face, and it can be circular or square at outer shoulder (outer periphery) 22a of the non-optical acting surface of optical surface 21a periphery.For optical mirror slip can fixed sealing be loaded in the camera lens (lens), optical mirror slip is to be fixed in earlier that a holding ring/or support (holding ring/ or holder) 10a is last to constitute an optical mirror slip group/or assembly (optical lensset/ or assembly) 1a; Described clamping frame 10a can be metal or plastic material is made, in order to location and fixing described a plurality of optical mirror slips, make its central shaft that can aim at camera lens (optical axis), even can by actuating mechanism (actuator) support can be moved to reach the purpose of zoom in camera lens in addition, as U.S. Pat 7,312,933, US7,095,572, US2007/0024989 and Jap.P. JP3650594 etc.
The fixing means of the optical mirror slip of existing plastic cement or glass material and support (can be metal or plastic material is made) as shown in Figure 1, especially the fixing means of the optical mirror slip made from glass material, be the support 10a that designs suitable groove earlier according to the outer shoulder 22a shape (as circular or square) of optical mirror slip 20a, but the profile of support does not limit as circular or square, again optical mirror slip 20a is inserted in the default groove of support 10a and locate, fix with viscose glue again; Described viscose glue often solidifies glue for UV, generally needs to be shone curing through program curing as utilizing the UV curing oven again; Because optical mirror slip is very little, when using automation or artificial gluing, often cause optical surface 21a scratch or drip and be stained with viscose glue (glue promptly overflows) with positioning and fixing, cause operation time-consuming and fraction defective is high; When especially positioning fixedly for the support of the optical glass lens of glass material and plastic cement material, it is more difficult that UV solidifies the glue operation, fraction defective height and UV curing oven are consuming time, cause cost and can't reduce always, as Jap.P. JP3791615, JP06258562 and U.S. Pat 7224542, US2007/0047109.
A kind of inserts is imbedded earlier carried out ejection formation again in the die cavity, be called flush type injection forming method (insert injection molding method), it is that an inserts (being generally metalwork) is inserted earlier in the die cavity of preset die, reinject plastic cement (rubber) material of fusion to fill up in the die cavity a default forming area (space) and to coat part or all of inserts, through take out finished product behind the cooling curing in mould; This manufacture method is used among electronic component, connector, mechanical parts, the LED in a large number, as U.S. Pat 5,923, and 805, Taiwan patent TWM313317, Jap.P. JP07120610 etc.Making one when having the outer cover of plastic lens by this forming method again, be that housing with outer cover is that inserts is inserted earlier in the die cavity with plastic rubber material ejection formation one plastic lens being combined as a whole with housing again, and finish an integrated outer cover with plastic lens; Or be that inserts penetrates the outer cover with plastic lens of outer cover with the moulding that is combined as a whole with plastic rubber material again with the plastic lens, as Taiwan patent TW0528279, U.S. Pat 6,825,503; Or with the glass plate inserts and around glass plate, coat plastic material to form various utilizations such as Jap.P. JP62251113 such as window-glass.Or as U.S. Pat 6,710,945, it utilizes two plastic rubber material filling orifices with gradation ejection formation eyeglass and lens barrel, or is inserts with the infrared transmitting glass sheet, and ejection formation one bracket (mount) coats again.And for example U.S. Pat 7,332,110 etc., with frame is that inserts is inserted earlier in the die cavity of mould, utilize mold pressing (press molding) method, the preform (preform) of plastic lens is heated to softening, and utilizes the heating of mould and pressurization that the preset shape of die cavity is needed on the softening preform, so that preform is shaped to eyeglass and is combined into one with frame (inserts) simultaneously and forms glasses.Yet this mold pressing (press molding) method can't be applicable to the processing procedure that the support of the optical glass lens of glass material and plastic cement material is combined into one, because if use plastic rubber bracket to be inserts, the softening point temperature of optical glass is about 500 ℃, far above the deformation temperature of the plastic material of plastic rubber bracket as 80 ℃, when mould reached the softening point temperature of optical glass, plastic rubber bracket had been out of shape and can't moulding; Therefore, though mould pressing method also can be used for a large amount of productions, be that inserts, glass material are the material of mold pressing with the support of plastic cement material, then technical being difficult to realizes.
In addition in the manufacturing of camera lens module, propose optical mirror slip, keeper, sensing element etc. are inserted in the mould, utilize plastics to inject and form a camera lens module as U.S. Pat 2009/0059398; Or as Fig. 2, it is inserts that Taiwan patent M337077 proposes optical glass lens 20b (having two), shading ring plate 30b (having two), distance piece 40b (a slice is arranged), contraposition is in regular turn inserted among mould 31b, the 32b, utilizes plastic rubber ejaculate molding or compression-moulding methods to make a lens bracket and to coat above-mentioned described a plurality of inserts and form an optical glass camera lens module again.But this technology can not be used in made up finish pile up camera lens secondary module (stacked lens submodule), be the structure that a close set is integrated because of piling up the camera lens secondary module, can not be separated into single element and insert in the mould respectively; Because the center of each optical mirror slip (as optical glass lens 20b), optical element (as shading ring plate 30b, distance piece 40b) is difficult to align each other,, causes and yield poorly and shortcoming that degree of accuracy is not high again so need expend sizable being operated in the correction in the heart.
Because the demand of high-accuracy camera lens, pile up the lens bracket precision prescribed height of camera lens secondary module outside, and the bearing accuracy of piling up camera lens secondary module and lens bracket will influence the imaging of camera lens, therefore how will pile up the camera lens secondary module and lens bracket aligns optical centre, will influence the resolution of lens imaging; For developing new technology, especially apply to pile up the combination of camera lens secondary module and lens bracket, and simple and easy processing procedure, the good camera lens module of mass production production bearing accuracy, will be for urgently required.
