Specific embodiment
Refer to Fig. 1 and Fig. 2, the camera lens module 100 that first embodiment of the invention is provided, including lens barrel 10, from thing
Side to image side is contained in 11, second lens of in the lens barrel 10 and with same optical axis AA first lens successively
12nd, 13, one, the 3rd lens, 15, baffle ring 16 of the 4th lens of spacer ring 14, and an infrared fileter 17.
First lens 11, the second lens 12 and the 3rd lens 13 are mutually clamped.3rd lens 13 are saturating with the 4th
The spacer ring 14 is set between mirror 15.
4th lens 15 include an optical section 151 and a non-optical division 152 around the optical section 151.
The part of optical effect is played in the as lens of the optical section 151, the optical section 151 is used to carry out optical imagery to light.
The non-optical division 152 surrounds and connects the optical section 151, and Main Function is placement, supports the optical section 151.
The baffle ring 16 is substantially circular and is made of plastics or rubber, and it is arranged on the non-optical division 152
Between the infrared fileter 17.The baffle ring 16 is used to hold the 4th lens 15.It is described to stop in present embodiment
Baffle ring 16 is made of black plastic, and the non-optical division 152 along the optical axis AA directions on the baffle ring 16 just
Projection falls completely within the baffle ring 16.The thickness of the baffle ring is about 0.25 millimeter.
The infrared fileter 17 includes the glass substrate 171 and an anticracking film 172 for annular of circle.It is described
Glass substrate 171 is processed by rounding.The glass substrate 171 can carry out plated film in a transparent glass surface so that
The clear glass has the ultrared function of filtering, or with filtering infrared function coloured glass.Present embodiment
In, the glass substrate 171 is processed for coloured glass through rounding, and it includes a pair opposite surfaces 1711.
The anticracking film 172 is annular transparent plastic sheet, and its thickness is about 0.035 millimeter.Outside the anticracking film 172
The diameter correspondent equal of footpath and the glass substrate 171.The anticracking film 172 is pasted on wherein the one of the glass substrate 171
Individual surface 1711, specifically, the anticracking film 172 is pasted on a table of the glass substrate 171 near the baffle ring 16
The face 1711 and anticracking film 172 is coaxially disposed with the glass substrate 171.The anticracking film 172 is arranged on the baffle ring
Between 16 and the glass substrate 171, the outer of the anticracking film 172 is alignd with the outer of the glass substrate 171.
Due to the glass substrate 171 for glass is processed into by rounding, the periphery of the glass substrate 171 after processing
There is the machining stress of remnants at edge, when colliding, is easier to chipping.The anticracking film 172 is pasted on the glass
Substrate 171 is close to a surface 1711 of the baffle ring 16, in this way, the anticracking film 172 can increase the glass substrate
The intensity of 171 peripheral edge.When the glass substrate 171 is loaded into the lens barrel 10, the anticracking film 172 can prevent institute
State the inwall collision of the peripheral and lens barrel 10 of glass substrate 171 and produce glass granules and fall into the 4th lens 15
On.
The camera lens module 100 can include two anticracking films 172, and two anticracking films 172 are pasted on the glass respectively
Two surfaces 1711 of substrate 171, in this way, can more effectively prevent the peripheral chipping of the glass substrate 171 and produce
Particulate.
As shown in figure 3, be the camera lens module 100 of second embodiment of the invention, including lens barrel 10, from thing side to picture
Side is contained in 11, second lens 12, of in the lens barrel 10 and with same optical axis AA first lens successively
13, one, individual 3rd lens, 15, infrared fileter 17 of the 4th lens of spacer ring 14,.
Difference with first embodiment is that the camera lens module 100 of present embodiment eliminates the baffle ring
16, the circular anticracking film 172 is black plastic piece, and specifically, the anticracking film 172 is an anti-dazzling screen.The anti-dazzling screen
It is to form thin by the condensation polymer (polyethylene terephthalate polyester, PET polyester) of terephthalic acid (TPA) and ethylene glycol
Film, then by the stamped shaping of film.The thickness of the anticracking film 172 is about 0.035 millimeter.The external diameter of the anticracking film 172
With the diameter correspondent equal of the glass substrate 171.The anticracking film 172 is pasted on one of them of the glass substrate 171
Surface 1711, specifically, the anticracking film 172 is pasted on a table of the glass substrate 171 near the non-optical division 152
The face 1711 and anticracking film 172 is coaxially disposed with the glass substrate 171, outer and the glass of the anticracking film 172
The outer alignment of substrate 171.Orthographic projection of the non-optical division 152 along the direction of the optical axis AA on the anticracking film 172
Fall completely within the anticracking film 172.In this way, the anticracking film 172 can not only absorb the light from the non-optical division 152
Line, and can effectively prevent the fragmentation of the glass substrate 171 and produce glass granules.Further, since present embodiment is saved
The baffle ring 16, can further reduce the size of the camera lens module 100.
In present embodiment, the camera lens module 100 can also include two anticracking films 172, and two anticracking films 172 are distinguished
It is pasted on two surfaces 1711 of the glass substrate 171.
It is understood that those skilled in the art can also do other changes etc. used in of the invention in spirit of the invention
Design, without departing from technique effect of the invention.These changes done according to present invention spirit, should all be included in
Within scope of the present invention.
