In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.

In the related art, the lens of the flash lamp is mostly designed by bonding glass and a membrane, and since an Optical Clear Adhesive (OCA) for bonding the glass and the membrane is made of a transparent material, when the flash lamp is turned on, light generated by the flash lamp propagates (refracts, reflects, and totally reflects) by using the OCA as a medium, thereby causing a problem of framing interference to the photographing device.

In the related art, in order to solve the above problem, a design of drilling a hole in the glass of the flash lamp region to move the position of the flash lamp forward and then adding a light blocking cover in the hole or adding an optical blocking coating around the camera on the photographing device is often adopted. For the former related technology, because glass has the characteristics of high hardness and low brittleness, the problem of reduction of the overall strength of the lens is easily caused by the holing treatment of the glass, and the whole processing process relates to the process of assembling various parts, so that the complexity of the overall structure is increased, the replacement and maintenance of parts are inconvenient for the final finished product, and the manufacturing cost is also increased; for the latter related technology, in order to improve the light shielding rate of the camera to the light of the flash lamp, the glass needs to be designed in a segmented manner, the complexity of the overall structure is increased, the camera of each shooting device needs to be subjected to light shielding treatment, the processing flow and complexity are further increased, and the implementation cost is also increased.

Referring to fig. 1, a lens structure 10 for a flashlight 20 is provided according to an embodiment of the present invention. The lens structure 10 includes a light-transmitting plate 11 and a blocking glue 12. The light-transmitting plate 11 comprises a glass layer 13, a glue layer 14 and a membrane layer 15. The glue layer 14 adhesively bonds the glass layer 13 and the membrane layer 15. The glass layer 13 has a flash region 16 thereon corresponding to the flash 20. The flash 20 is inserted through the flash through hole 17 formed in the diaphragm layer 15 and abuts the flash region 16. The barrier glue 12 is arranged around the flash lamp 20 along the inside of the edge of the flash lamp through hole 17.

Specifically, by disposing the blocking glue 12 around the flash area 16, the problem of framing interference caused by the light of the flash 20 can be prevented, which is beneficial to eliminating the photo crosstalk defect.

Above-mentioned lens structure 10 glues 12 through the separation that adopts around flash light 20 setting, can reduce flash light 20's luminousness to can solve the framing interference problem that flash light 20 caused under the prerequisite that does not influence glass intensity and do not change the CMF effect.

Referring to fig. 1, in some embodiments, the height H1 of the barrier paste 12 is greater than or equal to 0.1 mm in a direction perpendicular to the plane of the light-transmitting plate 11. Along the direction parallel to the plane of the light-transmitting plate 11, the width W of the cross section of the blocking glue 12 is less than or equal to 0.5 mm. Specifically, height H1 more than or equal to 0.1 millimeter of separation glue 12 can make separation glue 12 easily set up on glass layer 13, and cross-sectional width W less than or equal to 0.5 millimeter can guarantee that separation glue 12 has the luminousness that is little enough, and can not influence the structural strength of glass layer 13. In this way, the impact on the CMF effect can be minimized. In one embodiment, the height H1 of the barrier coat 12 is 0.12 millimeters and the overall thickness of the glue layer 14 and the film layer 15 is 0.1 millimeters.

In some embodiments, the barrier glue 12 has a light transmission of less than 1%.

For barrier glue 12, in some embodiments, it may be adhesively disposed on glass layer 13.

In certain embodiments, the thermal curing temperature of the barrier glue 12 is less than 150 ℃. Specifically, when the barrier paste 12 is disposed on the glass layer 13 by means of a heat curing process, since the heat curing temperature is at most 150 ℃, in the case of the heat curing process for the barrier paste 12, the physical structure of the barrier paste 12 may change, so that the physical structure itself has a large viscosity and a good thixotropic property, and thus can be easily adhered to the glass layer 13. Thus, the processing and assembly of the barrier rubber 12 can be facilitated. In one embodiment, the processing of the barrier glue 12 is a silk-screen process.

Of course, it will be apparent to those skilled in the art from this disclosure that the barrier paste 12 can be disposed on the glass layer 13 in other ways (e.g., snap connection, interference connection) to achieve the same or similar technical effects as the embodiments of the present disclosure.

In certain embodiments, the material composition of the barrier gum 12 includes a black fiber thixotropic agent. The specific weight of the black fiber thixotropic agent was [ 0.4%, 0.5% ]. Specifically, in one embodiment, the material composition of the barrier glue 12 includes methyl tetrahydrophthalic anhydride, an alicyclic amine addition epoxy resin, a cycloaliphatic epoxy resin, and a black fiber thixotropic agent. Wherein, under the condition that the specific weight of the black fiber thixotropic agent is 0.4 percent and 0.5 percent, the barrier glue 12 can be used for silk-screen processing treatment, and the fluidity of the barrier glue 12 can be reduced to the maximum extent so as to increase the viscosity of the barrier glue.

Referring to fig. 1 and 2, a method for manufacturing a lens structure 10 according to an embodiment of the invention is provided, in which the lens structure 10 is used for a flashlight 20. The lens structure 10 includes a light-transmitting plate 11 and a blocking glue 12. The light-transmitting plate 11 comprises a glass layer 13, a glue layer 14 and a membrane layer 15. The glue layer 14 adhesively bonds the glass layer 13 and the membrane layer 15. The glass layer 13 has a flash region 16 thereon corresponding to the flash 20. The flash 20 is inserted through the flash through hole 17 formed in the diaphragm layer 15 and abuts the flash region 16. The barrier glue 12 is arranged around the flash lamp 20 along the inside of the edge of the flash lamp through hole 17. Referring to the drawings, the manufacturing method comprises:

01: pre-shading by a screen printing ink black ring 18 at a position on the glass layer 13 around the flash lamp area 16;

02: stacking and printing treatment is carried out through the barrier glue 12 along a track formed by the screen printing ink black ring 18 through pre-shielding treatment;

03: performing heat curing treatment on the glass layer 13 after the printing treatment;

04: the glass layer 13 after the heat curing process is bonded to the film layer 15.

In the manufacturing method of the lens structure 10, the barrier glue 12 arranged around the flash 20 is adopted, so that the light transmittance of the flash 20 can be reduced, and the problem of framing interference caused by the flash 20 can be solved on the premise of not influencing the glass strength and not changing the CMF effect.

Specifically, referring to fig. 3, in 01, the position where the barrier adhesive 12 is disposed is determined by confirming the position where the barrier adhesive 12 is disposed on the glass layer 13 with a processed appropriate size, and then the position where the barrier adhesive 12 is disposed is subjected to pre-shielding treatment by using the screen printing ink black ring 18. In 02, the orbit of forming along silk screen printing ink black circle 18 is glued 12 to the separation and is piled high printing, can conveniently confirm the position that sets up separation on needs glass layer 13 and glue 12, is favorable to accelerating machining efficiency to can make silk screen printing ink black circle 18 can glue 12 to the separation and carry out the sheltering from of sight, thereby can not observe the setting that the separation glued 12 in one side in addition of glass layer 13. In 03, after printing of the barrier paste 12 is completed, the barrier paste 12 can be cured on the surface of the glass layer 13 through a heat curing process of the glass layer 13, so that the firmness degree of the adhesion between the barrier paste 12 and the glass layer 13 is increased. In 04, the film layer 15 is attached to the surface of the glass layer 13 according to the relevant design requirements, so that the barrier adhesive 12 can be blocked between the film layer 15 and the flash lamp 20 located in the flash lamp area 16, and the problem of incomplete shielding caused by attaching the film layer 15 first and then adhering the barrier adhesive 12 is avoided.

In one embodiment, the track width formed by the screen printing ink black ring 18 after the pre-shielding treatment is greater than the section width W of the barrier glue 12, so that the shielding effect of the screen printing ink black ring 18 on the barrier glue 12 can be ensured.

In some embodiments, the printing process of stacking is performed by the blocking paste 12 along the track formed by the pre-masking process of the screen printing ink black circle 18, and includes:

021: the barrier paste 12 is stacked along the surface of the track by a screen printing plate.

Thus, the setting of the barrier glue 12 can be facilitated.

Specifically, the screen printing plate is used for stacking the blocking glue 12 on the surface of the screen printing ink black ring 18 along the track, so that the printing times of the blocking glue 12 can be reduced, the increase of the section width W of the blocking glue 12 due to repeated printing is avoided, and the integral processing efficiency is facilitated. In one embodiment, the thickness of the glass layer 13 along the cross section is 0.5 mm, and the width W of the cross section of the barrier paste 12 can be about 0.45 mm when the barrier paste 12 is stacked on the surface of the glass layer 13 by printing to a height H1 of 0.1 mm.

For a screen, in one embodiment, the screen mesh is 100. In other embodiments, the mesh number of the screen plate can be determined according to specific situations, or the mesh number of the screen plate can be calibrated through actual tests.

In addition, referring to fig. 1, in some embodiments, the height H1 of the stack of barrier ribs 12 is greater than the thickness H2 of the film layer 15, and the difference between the height H1 and the thickness H2 is greater than 0.02 mm. In this way, the light of the flash lamp 20 can be prevented from propagating outwards along the gap between the barrier adhesive 12 and the film layer 15 to cause interference.

Further, in such an embodiment, the material composition of the barrier gum 12 includes a fibrous thixotropic agent. Therefore, the blocking glue 12 can be guaranteed to have good operability (for example, meshes can be prevented from being blocked) when being printed through the screen printing plate, and the self flowability can be reduced as much as possible, so that the section width W of the blocking glue 12 is guaranteed to be reduced, and the appearance influence on the CMF can be reduced.

In certain embodiments, the temperature of the thermal curing process is 150 ℃ and the time of the thermal curing process is 15 minutes. It can be understood that, for the glass layer 13 subjected to the thermal curing process, the barrier glue 12 on the surface thereof is still in a flowable state, and in the case of performing the thermal curing process at a temperature of 150 ℃ for a duration of 15 minutes, the adhesion strength of the barrier glue 12 on the surface of the glass layer 13 can be effectively improved, and at the same time, the barrier glue 12 can be prevented from being brittle and fragile due to being heated for a long time.

Referring to fig. 1, 4 and 5, a photographing apparatus 100 according to an embodiment of the present invention includes a camera 30, a flash 20 and a lens structure 10 according to any of the above embodiments. The camera 30 and the flash 20 are arranged on the same side of the glass layer 13 of the light-transmitting panel 11.

Above-mentioned shooting equipment 100, through adopting the separation glue 12 that sets up around flash light 20, can reduce the luminousness of flash light 20 to can be under the prerequisite that does not influence glass intensity and do not change the CMF effect, solve the framing that flash light 20 caused and interfere the problem.

Specifically, in the embodiment shown in fig. 5, the camera 30 and the flash 20 are disposed on the same side of the glass layer 13, and the camera 30 is perforated with a through hole formed by the glue layer 14 and the diaphragm layer 15 to abut against the glass layer 13. Because the separation is glued 12 and is set up around flash light 20, can carry out the separation to the light that flash light 20 sent for its light can't propagate to camera 30 department along the diaphragm layer 15 that is located between camera 30 and flash light 20, thereby can realize avoiding flash light 20 to produce the problem of finding a view and interfering to camera 30.
