Embodiment
Below in conjunction with drawings and the specific embodiments, camera module and support thereof are further detailed.
As shown in Figure 1, the camera module 10 of an execution mode, comprises support 100, circuit board 200, image sensing chip 300, cutoff filter 400, voice coil motor 500 and camera lens 600.
As shown in Figures 2 and 3, support 100 comprises cylindrical shell 110, mounting panel 120 and loading plate 130.
Cylindrical shell 100 has the first relative end face 112 and the second end face 114.In the present embodiment, cylindrical shell 100 is square.In other embodiments, cylindrical shell 100 also can be cylindrical.
Mounting panel 120 has relative first surface 122 and second surface 124.Mounting panel 120 is located in cylindrical shell 110, and first surface 122 flushes with the first end face 112 and forms connecting surface 140.Mounting panel 120 is provided with the loophole 126 running through first surface 122 and second surface 124.Loophole 126 is for accommodating cutoff filter 400.
Wherein, connecting surface 140 is for connecting voice coil motor 500, and the second end face 114 is for connecting circuit board 200.Mounting panel 120 is provided with the escape hole 128 running through first surface 122 and second surface 124, escape hole 128 and loophole 126 phase independent (being staggered), and is positioned at the periphery of loophole 126.On the direction along first surface 122 to second surface 124, escape hole 128 has mutated site 150, the internal diameter that escape hole 128 is positioned at mutated site 150 place is less than the internal diameter that escape hole 128 is positioned at first surface 122 place.
The principle adopting one end of the glue sealing escape hole with mobility is that, when after blade coating one deck glue in connecting surface 140, glue is inserted in one end of escape hole 128, thus is blocked one end of escape hole 128.And weaken along with the increase of time due to the mobility of glue, after certain hour, namely can lost flowability, thus one end of escape hole 128 can be sealed.Under desirable state, the other end of glue blow-by escape hole 128.
The internal diameter of the escape hole on traditional support is consistent everywhere, namely common circular hole, when escape hole being carried out to filler to seal escape hole when one end of voice coil motor, because glue has certain mobility, the phenomenons such as the sliding glue of easy appearance, leakage glue now, are nonideality, causing part glue to be departed from support by escape hole and dropped to image sensing chip makes chip be polluted, and then causes camera module defective.
In order to avoid the appearance of nonideality, in the present embodiment, by changing the internal diameter of escape hole 128, the internal diameter of escape hole 128 is suddenlyd change at mutated site 150 place, thus when there being glue to flow to mutated site 150 from first surface 122 place, the internal diameter being positioned at mutated site 150 place due to escape hole 128 is less than the internal diameter that escape hole 128 is positioned at first surface 122 place, the flow path of glue can be increased, thus increase the flowing time of glue, simultaneous mutation position 150 changes the flow direction of glue, increase the flow resistance of glue, thus also can increase the flowing time of glue, and then accelerate the solidification of glue, can effectively avoid occurring sliding glue, leak the phenomenons such as glue.
And when above-mentioned camera module 10 is applied to mobile terminal (as mobile phone, IPAD etc.), because mobile terminal is free articles under passenger, constantly undergo vibrations, the glue of solidification may rupture because of vibrations, and then generation micelle, there is the risk that micelle drops on image sensing chip 300 along escape hole 128, and then affect the quality of imaging.And be less than the internal diameter at first surface 122 place due to the internal diameter at mutated site 150 place, also namely mutated site 150 protrudes relative to first surface 122, thus mutated site 150 can accept micelle, and then can stop that micelle falls on image sensing chip 300, thus above-mentioned camera module 10 is made to have good image quality.
Further, excessive glue groove 116 is provided with at the edge of the first end face 112.When voice coil motor 500 is connected by glue with connecting surface 140, the glue groove 116 that overflows, for accommodating the unnecessary glue overflowed because of extruding, in order to avoid camera module 10 size exceeds scope of design, affects yield.
Loading plate 130 has the first relative loading end 132 and the second loading end 134.Loading plate 130 is located in loophole 126, the first loading end 132 near first surface 122, for carrying cutoff filter 400.Loading plate 130 is provided with the mating hole 136 of through first loading end 132 and the second loading end 134.Concrete, in the present embodiment, on the direction along the first loading end 132 to the second loading end 134, the internal diameter continuity of mating hole 136 increases.
