Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Figures 1 and 2, it is respectively the STRUCTURE DECOMPOSITION figure of a kind of mobile phone camera module 10 under two different visual angles.A kind of mobile phone camera module 10 comprises: microscope base 100, camera lens 200, PCB 300, sensitive chip 400 and flexible circuit board 500.
Camera lens 200 is installed on microscope base 100, PCB 300 is for carrying sensitive chip 400 and fixing microscope base 100, sensitive chip 400 is installed in PCB 300, sensitive chip 400 is arranged in microscope base 100 and corresponding with camera lens 200, and flexible circuit board 500 is connected with PCB 300 and is connected with external circuit.
Microscope base 100 comprises motor 110, support 120 and filter 124, and motor 110 is connected with support 120, and PCB 300 is connected with support 120, and sensitive chip 400 is contained in PCB 300 and is connected with support 120 and in the cavity formed.Be noted that, carrier 112 is provided with in motor 110, the inner ring of carrier 112 offers the first thread groove 114, camera lens 200 offers the second thread groove 210, first thread groove 114 and the second thread groove 210 screw togather, by coordinating of the first thread groove 114 and the second thread groove 210, camera lens 200 can be screwed together on carrier 112.Carrier 112 is arranged with coil, motor 110 is built-in with magnet, coil is in the magnetic field of magnet, the coil of energising is subject to acting in magnetic field of magnetic field force and moves, so coil drives the carrier 112 be attached thereto to move, carrier 112 is equiped with camera lens 200, camera lens 200 finally just can be driven to move, thus achieve the focusing of camera lens 200.Current vanishes in coil, magnetic field force disappears, and carrier 112 resets, the reset of resulting belt index glass head 200.
As shown in Figure 3, it is the enlarged drawing of mobile phone camera module 10 at A place shown in Fig. 1.Support 120 offers optical filtering hole 122, the edge in optical filtering hole 122 is provided with annular stop block 127, and guide vane end stop 127 has a unfilled corner 129, and filter 124 to be contained in guide vane end stop 127 and to be closed in optical filtering hole 122.Guide vane end stop 127 pairs of filters 124 serve spacing effect, effectively prevent the generation of the shift phenomenon of filter 124.Meanwhile, guide vane end stop 127 has a unfilled corner 129, when filter 124 takes out from support 120 by needs, and can by the unfilled corner 129 offered filter 124 be taken out from support 120 easily and fast.
In the present embodiment, optical filtering hole 122 is square opening, and filter 124 is square plates.In other embodiments, optical filtering hole 122 and filter 124 can also be other shape.
As shown in Figure 4, it is the enlarged drawing of mobile phone camera module 10 at B place shown in Fig. 1.Especially, support 120 is provided with reference column 126, PCB 300 offers the location hole 310 corresponding with reference column 126, and reference column 126 is contained in location hole 310, thus support 120 is fixed in PCB 300.Camera lens 200 can be taken off when the product after assembling finds that there is dust to clean, again microscope base 100 is assembled in PCB 300 after clean, solve the problem that product can be caused to offset when microscope base 100 attachment needs repairing after PCB 300 by this kind of scheme, the problem of skew makes sensitive chip 400 inaccurate with the center contraposition of microscope base 100.And coordinating by reference column 126 and location hole 310, add the maintenanceability of product, when finding that there is bad, product is done over again maintenance, makes product not have shift phenomenon, greatly improves the yield of product.
In the present embodiment, the quantity of reference column 126 is two and for cylindrical, the quantity of location hole 310 is two and is manhole, two reference columns 126 respectively with two location hole 310 one_to_one corresponding.Arrange respectively two reference columns 126 and two location holes 310 be the most fast, the simplest and the most direct locate mode, on the one hand, can ensure that two reference columns 126 are accurately located with two location holes 310 respectively, on the other hand, can ensure that support 120 can not produce relative rotation after being fixed on PCB 300.
The assembling process of mobile phone camera module 10 mainly comprises wafer welding, bonding wire and microscope base assembling.
Wafer welding refers to and mounts in PCB 300 by sensitive chip 400, the picture glue pattern write is utilized board image recognition system by red tempera painting at sensitive chip 400 paste position, again the sensitive chip 400 of well cutting is covered on picture glue position, then use high-temperature baking, the sensitive chip 400 pasted is fixed in PCB 300.
Bonding wire utilizes hot pressing and ultrasonic wave to be welded on by gold thread in sensitive chip 400 and PCB 300, thus complete microelectronic component lead frame and be connected with the circuit of chip.
Microscope base assembling is assembled in by image sensor to mount in the PCB 300 of sensitive chip 400.Mainly utilize the picture colloid system of board and optical recognition system by black tempera painting in PCB 300, then microscope base 100 is mounted on the position corresponding with sensitive chip 400.
Be compared to traditional encapsulation technology, the product quality that the assembling process of this kind of mobile phone camera module 10 is manufactured out is higher, small volume, and cost is lower, is popularized due to the cheap and technical maturity of its sensitive chip 400 adopted.
In the assembling process of product, when finding that sensitive chip 400 has granule, need to keep in repair, microscope base 100 and PCB 300 are carried out be separated clean after re-assembly again, by arranging reference column 126 and location hole 310, the accuracy of assembling can be ensured very well, make product not have shift phenomenon, greatly improve the yield of product.Meanwhile, be provided with annular stop block 127 at the edge in optical filtering hole 122, namely can play position-limiting action to filter 124, can fast and effectively filter 124 be taken out from guide vane end stop 127 again.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
