Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail.
Refer to Fig. 1, for the side schematic view of battery of lens fixing device in one embodiment of this utility model.
Battery of lens fixing device in the present embodiment includes optical bracket the 110, first lens 120 and the second lens 130.
Specifically, optical bracket 110 is provided with the first installing hole 112 and the second installing hole 114.Wherein, the radius of the first installing hole 112 is less than the radius of the second installing hole 114.First lens 120 are fixed in the first installing hole 112, and the second lens 130 are fixed in the second installing hole 114.
Wherein, first installing hole 112 be formed around multiple breach 122 (not shown in figure 1), second installing hole 114 be formed around multiple breach 132 (not shown in figure 1), above-mentioned multiple breach is filled with fixing glue (not shown) in (122,132), so that the first lens 120 and the second lens 130 are separately fixed at the first installing hole 112 and neutralize in the second installing hole 114.
Incorporated by reference to Fig. 2, it it is the front schematic view of battery of lens fixing device in an embodiment.
In the present embodiment, the first installing hole 112 be formed around 4 breach 122, the second installing hole be formed around 4 breach 132.Being appreciated that in other embodiments, the surrounding of the first installing hole 112 and the surrounding of the second installing hole 114 can also arrange the breach of respective number according to actual needs, the most strictly limit.
In one embodiment, 4 breach 122 are evenly distributed in the surrounding of the first installing hole 112, and 4 breach 132 are evenly distributed in the surrounding of the second installing hole 114.The first lens 120 and the second lens 130 so can be made to be firmly secured on optical bracket 110.
In one embodiment, above-mentioned fixing glue is flexible glue.Being appreciated that in other embodiments, described fixing glue can also be other kind glue with binding function.
In one embodiment, the first lens 120 and the second lens 130 are for being coaxially disposed.
During assembling, first optical bracket 110 is placed on the tool that flatness is good, again the first lens 120 are put in the first installing hole 112 of correspondence, tool is developed in bottom, make bottom the bottom of optical bracket 110 and the first lens 120 at grade, then to use adhesive supplier along 122 dozens of a small amount of flexible glues of 4 breach.After the first lens 120 gluing completes, the second lens 130 are placed in the second installing hole 114, after setting level, fix the second lens 130 according to the gluing mode of the first lens 120, then place a period of time and treat that flexible glue parches.
Also provide for a kind of optical system, including above-mentioned battery of lens fixing device.This optical system also includes such as the parts such as panel, light source, and its operation principle is well known to those skilled in the art, repeats no more here.
Said lens group fixing device and optical system, by the most all arranging multiple breach in the surrounding of the surrounding of described first installing hole and described second installing hole, and in multiple described breach, fill fixing glue, described first lens and described second lens are made to have certain contact area with the fixing glue filled respectively, thus reach fixed first lens and the purpose of the second lens, so need not additionally to use again the shell fragment mode that screws the first lens and the second lens to be directly anchored on support, thus save space and infrastructure cost, also it is effectively improved optical efficiency simultaneously.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, all it is considered to be the scope that this specification is recorded.
