Abstract
Disclosed is a bottom contact gold finger fixed-focus camera module for a mobile phone, which comprises a lens, a lens holder, a CMOS photosensitive chip and a circuit board. The lens and the lens holder are connected into a whole body through screw threads; the lens holder is installed on the circuit board; the CMOS photosensitive chip is arranged on the circuit board encapsulated in the lens holder, with the sensitivity center coinciding with the with the optical axis of the lens; a connecting gold finger is printed at the underside of the circuit board; and a clamping slot and a fool-proof projection are arranged on the lens holder. In addition, the utility model discloses an assembling method of the bottom contact gold finger fixed-focus camera module. The gold finger has a large contact area, so the contact is sufficient; and the clamping slot arranged on the lens holder matches with the clamping position on the mobile phone, so the module can be positioned stably and accurately and can be applicable on an ultra-thin mobile phone, thus reducing material and manpower cost, improving the production efficiency and simplifying the process.
Description
Technical field
The utility model relates to a kind of small-sized image collection device field, the bottom-contact golden finger type fixed-focus of using for a kind of mobile phone specifically shooting module.
Background technology
Along with popularizing of colour screen handset, camera function wherein more and more is subject to people's attention.The cell-phone camera module is as the image collection device of mobile phone, generally is made up of parts such as CMOS sensitive chip, optical lens, soft or hard circuit board, patch capacitor, Chip-R, connectors.
The cell-phone camera module mainly contains two big classes by the lens focus branch, and a kind of is to focus the shooting module, and another kind is constant, has been fixed on the image-forming range an of the best before dispatching from the factory.
Traditional cell-phone camera module is connected by the connector connected mode, and connector joins with connector pinout and circuit board.Because contact area is less, and the dimension precision requirement to connector is higher, increased the cost of whole mobile phone cam module, reduced the efficient of producing, and anti-dropping, shock resistance is poor, in use be given a shock or external impacts the time, be easy to cause connect looseningly, cause product normally not use.And the shooting module that adopts connector to connect need take certain space owing to connector, can't effectively the module overall height be reduced, and can't satisfy the requirement of some ultra thin handset.
The utility model content
The purpose of this utility model is the deficiency that exists at existing connector form cell-phone camera module, provide a kind of antidetonation, anti-drop, highly little, more save artificial and Material Cost, more can simplify the bottom-contact golden finger type fixed-focus mobile phone camera module of technological process.
The utility model is achieved in that the bottom-contact golden finger type fixed-focus mobile phone camera module, comprise camera lens, microscope base, CMOS sensitive chip and circuit board, camera lens and microscope base are by being threaded to one, microscope base is connected with circuit board, the CMOS sensitive chip is encapsulated on the interior circuit board of microscope base, the sensitivity centre of CMOS sensitive chip and the optical axis coincidence of camera lens are printed with the connection golden finger in the bottom surface of circuit board, and connector conducts connection before replacing.
Described microscope base is provided with draw-in groove,
Described draw-in groove can be provided with 4, lays respectively at four jiaos of microscope base.
Described microscope base is provided with the fool proof projection so that and module has directivity, make things convenient for subsequent installation.
Described CMOS sensitive chip is by on the circuit board of chip mounter paster in the microscope base.
Described microscope base is to be fixed on the circuit board by hot-setting adhesive.
Described circuit board is a hard circuit board.
The utility model bottom-contact golden finger type fixed-focus mobile phone camera module is that the golden finger by the below of hard circuit board connects, the contact area of golden finger is big, full contact, and 4 positioners on the draw-in groove matching with mobile phone are being arranged on the microscope base makes module steady positioning, accurately.Solved the vibrations of shooting module, the stability problem when falling, and effectively reduced the height of shooting module, the shooting module can be applicable in the ultra thin handset use.Because of not having connector on the bottom-contact golden finger type fixed-focus mobile phone camera module, reduced material and cost of labor, improved the efficient of producing, simplify technological process.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model bottom-contact golden finger type fixed-focus shooting module is described in detail.
Bottom-contact golden finger type fixed-focus mobile phone camera module such as Fig. 1～shown in Figure 4, comprise parts compositions such as camera lens 1, microscope base 2, CMOS sensitive chip 3, circuit board 4.What circuit board 4 was selected for use is hard circuit board.Camera lens 1 and microscope base 2 are by being threaded to one, and microscope base 2 is installed on the circuit board 4, and CMOS sensitive chip 3 electronic components such as grade pass through the chip mounter paster to hard circuit board 4, the optical axis coincidence of the sensitivity centre of CMOS sensitive chip 3 and camera lens 2.Microscope base 2 is provided with draw-in groove 5, and draw-in groove 5 can be provided with 4, lays respectively at four jiaos of microscope base 2.After the draw-in groove 5 of microscope base 2 made the shooting module be installed to mobile phone, the positioner of mobile phone can be stuck on the draw-in groove 5 of shooting module, played the effect of fixing shooting module.On microscope base 2, be provided with fool proof projection 6 so that and the shooting module have directivity, the module of will making a video recording when having avoided assembling is adorned wrong direction.Be printed with in the bottom surface of circuit board 4 and connect golden finger 7, connector conducts connection before replacing.
The assemble method of bottom-contact golden finger type fixed-focus mobile phone camera module, realize by following steps:
A, paster: CMOS sensitive chip 3 is passed through the chip mounter paster to hard circuit board 4, the sensitivity centre of CMOS sensitive chip and the optical axis coincidence of camera lens.
B, assembling:, with hot-setting adhesive microscope base is adhered on the hard circuit board then with fitting together after camera lens 1 and microscope base 2 cleanings.
C, focusing: to the test pattern real scene shooting, regulate realistic bat effect by the orthogonal projection mode, make the real scene shooting effect reach the most clear.
D, focus: behind the junction of camera lens and microscope base, the bottom-contact golden finger type fixed-focus mobile phone camera module is passed through UV light consolidate the relative position of machine UV curing glue with fixed lens and CMOS sensitive chip with UV glue point.
The contact area of the golden finger of the utility model bottom-contact golden finger type fixed-focus mobile phone camera module is big, and full contact, and 4 positioners on the draw-in groove matching with mobile phone are being arranged on the microscope base makes module steady positioning, accurately.Solved module vibrations, the stability problem when falling, and effectively reduced the height of module, module can be applicable on the ultra thin handset use.Because of not having connector on the bottom-contact golden finger type fixed-focus mobile phone camera module, reduced material and cost of labor, improved the efficient of producing, simplified technological process.
