Detailed Description
The invention will be better understood from the following examples. However, those skilled in the art will readily appreciate that the description of the embodiments is only for illustrating the present invention and should not be taken as limiting the invention as detailed in the claims.
As shown in fig. 1, the utility model discloses an ultraviolet curing device for lens veneer, including base 9, the setting on base 9 veneer timing instrument 2 and be located the mount pad 4 of veneer timing instrument 2 top, mount pad 4 passes through fastening screw 5 to be fixed on lens center appearance objective 6, when needing ultraviolet curing, fixes mount pad 4 on lens center appearance objective 6 through fastening screw 5, after ultraviolet curing is accomplished, unscrews fastening screw 5, takes off mount pad 4 from lens center appearance objective 6, can observe the cemented lens after ultraviolet curing through lens center appearance objective 6 this moment; the ultraviolet curing device for lens gluing of the utility model also comprises an ultraviolet light source 7 and an ultraviolet reflecting mirror 3 which are fixed on the mounting seat 4, wherein the ultraviolet light source 7 is fixed in the mounting seat 4 through a locking screw 8, and the ultraviolet reflecting mirror 3 is bonded in the mounting seat 4 through glue; the to-be-cemented lens 1 (the to-be-cemented lens 1 comprises a lens 1-1 and a lens 1-2) is placed in the cementing adjustment tool 2, ultraviolet glue is coated between the positive lens and the negative lens (between the lens 1-1 and the lens 1-2) of the to-be-cemented lens 1, and the included angle between the extension line of the central axis A of the ultraviolet light source 7 and the ultraviolet reflector 3 is 45 degrees (namely, the included angle between the mirror surface of the ultraviolet reflector 3 and the horizontal plane is 45 degrees).
The point light source sent by the ultraviolet light source 7 irradiates on the lens 1 to be cemented through the ultraviolet reflector 3, and because of the equal optical path (because the included angle between the extension line of the central axis A of the ultraviolet light source 7 and the ultraviolet reflector 3 is 45 degrees), the irradiation intensity of the ultraviolet light on the surface of the lens is the same, thereby the cementing layer between the lenses is cured uniformly. After the gluing is finished, the aperture of the surface of the lens is smaller than 1.8, and the irregularity is smaller than 0.4, so that the requirement that the aperture and the irregularity of the glued surface reach high precision is met.
Ultraviolet glue is coated between a positive lens and a negative lens of a lens 1 to be cemented with high precision, the lens 1 to be cemented with high precision is placed in a cementing adjusting tool 2, an ultraviolet light source 7 is turned on, ultraviolet light irradiates on an ultraviolet reflecting mirror 3 at a certain angle and is reflected by the ultraviolet reflecting mirror 3 to irradiate on the lens 1 to be cemented, and due to the equal optical path of irradiation, the irradiation intensity of the ultraviolet light on the surface of the lens is the same, so that a cementing layer between the lenses is uniformly cured, and the aperture and the surface type change of the lens surface are small. Through measurement, the aperture surface shapes of the two surfaces of the cemented lens meet the high-precision requirement.
