Abstract
The utility model relates to a camera die set, particularly to a miniature camera die set, such as a preferred camera die set for a monitoring camera, a mobile phone and a laptop computer. The utility model has the technical scheme that the miniature camera die set is composed of a lens holder, a lens set, a filter, a circuit board and an external circuit connector, wherein the joint face of the lower sides of the lens holder is connected to a sensitization chip, and the lower side of the sensitization chip is connected with the circuit board via a welding ball. Compared with the prior art, the utility model does not need to additionally provided with a movable focus adjusting mechanism, and is favorable for microminiaturization and manufacturing cost reduction.
Description
Technical field
The utility model relates to a kind of shooting module, particularly a kind of miniature video camera module.Be such as the shooting module that monitors camera, mobile portable phone and notebook first-selection.
Background technology
In recent years, in various multimedias fields such as notebook, mobile phone, and in the image input device that monitors information terminals such as camera and video recorder, demand to small-sized or miniature information sensor assembly sharply increases, as the small-sized or miniature information sensor assembly that is applicable to described image input device, have solid-state imager, lenticular unit, optical filter and aperture parts etc. are housed in a photographing module in the encapsulation; Commonplace use normally by lens bracket and be installed in lens group, optical filter, sensitive chip in the lens bracket be located at its down, circuit board and external circuits connector constitute.Its assembly technology generally is earlier sensitive chip to be installed on the circuit board by solder sphere, and then lens bracket covered on the sensitive chip is loaded on the circuit.Described structure setting and fit just can not fully be guaranteed the precision of the position relation of solid-state imager and lens, particularly sensitive chip and lens bracket are contactless assembly relations, causing degree of tilt between sensitive chip and the lens bracket wayward is zero, although that is to say that existing certain between sensitive chip and the camera lens is that difficulty focusing also can be caused in very little inclination angle, just can not reach the requirement of image pattern resolution clearly of each position of image surface.Also Just because of this, the movable focus adjusting mechanism of packing in encapsulation and focusing that has is waited to assemble the back and is focused by the focus adjusting mechanism.This not only makes its complex structure increase manufacturing cost, and the defective that the volume as the photographing module of information sensing assembly is increased.When movable in addition focus adjusting mechanism was vibrated after goods are finished or impacts, therefore the easy change of focusing position caused reliability of products poor.Based on above-mentioned former tired existing photographing module further improved necessity is arranged.
The utility model content
The utility model puts forward at the problem that prior art exists, its purpose is to provide a kind of compact conformation, simple and guarantee the precision that the position of solid-state imager and lens concerns, and then reaches the designing requirement of drawing resolution clearly of each position of image surface.Improve the quality percentage and the picture quality of shooting module; Simultaneously do not need to establish focus adjusting mechanism in addition yet, be beneficial to the miniature video camera module of contract body and reduction manufacturing cost.
The technical scheme of the utility model technical solution problem is made up of lens bracket, lens group, optical filter, circuit board and external circuits connector, the faying face of its described lens bracket bottom and sensitive chip be in conjunction with linking to each other, the linking to each other with circuit board below by solder sphere of sensitive chip.
The optical axis that the plane of described sensitive chip is assembled on the lens bracket eyeglass in back and the lens group keeps plumbness.
After the combination of the lower end of described lens bracket and circuit board, its lower end and the circuit board maintenance certain spacing that do not contact each other.
Described circuit board is any one in PCB circuit board and the flexible PCB.
The utility model compared with prior art, owing to adopted the technical measures that lens bracket and sensitive chip are directly combined, and eliminated prior art fully through evidence and directly combine the position that makes between solid-state imager and the eyeglass because of lens bracket and sensitive chip are non-and concern that precision is low, and the degree of tilt such as between sensitive chip and the lens bracket that therefore causes is difficult to be controlled to be zero, and then cause shooting module difficulty focusing, even need set up series of malpractice such as movable focus adjusting mechanism; Have compact conformation, simple, the precision of guaranteeing the position relation between solid-state imager and the eyeglass, obviously improve the factor of merit and the picture quality of shooting module, the clear designing requirement that reaches image analytic degree in each position of image surface, do not need to establish in addition movable focus adjusting mechanism, be beneficial to little, microminiaturized and the reduction manufacturing cost.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram.
Fig. 2 is a front view structural representation of the present utility model.
Embodiment
The description that embodiment of the present utility model is detailed in addition in conjunction with the accompanying drawings, lens group 2, optical filter 3 are housed in the lens bracket 1 from top to bottom in turn, bonding sensitive chip 4, sensitive chip 4 is bonded together below by solder sphere 5 and pcb board or flexible PCB 6 on its following faying face 7, PCB circuit board or flexible PCB 6 link to each other with external circuits connector 8, after the plane of described sensitive chip 4 is assembled on the lens bracket 1 with lens group 2 in the optical axis of eyeglass keep plumbness; Described lens bracket 1 can make all size in order to its eyeglass that is complementary separately, optical filter 3, sensitive chip 4 supporting uses, and the lower end of assembling rear lens support 1 does not contact the maintenance certain spacing with circuit board.
Claims (4)
1, a kind of miniature video camera module, form by lens bracket (1), lens group (2), optical filter (3), circuit board (6) and external circuits connector (8), it is characterized in that the following faying face (7) of described lens bracket (1) links to each other with sensitive chip (4) combination, the linking to each other with circuit board (6) of sensitive chip (4) below by solder sphere (5).
2, a kind of miniature video camera module according to claim 1 is characterized in that the plane of described sensitive chip (4) is assembled to the optical axis maintenance plumbness that lens bracket (1) is gone up eyeglass in back and the lens group (2).
3, a kind of miniature video camera module according to claim 1, it is characterized in that the combination of described lens bracket (4) and circuit board (6) after, its lower end and circuit board (6) the maintenance certain spacing that do not contact each other.
