Description
[technical field]
The invention relates to a kind of eyeglass and process the method and apparatus of this eyeglass.
[background technology]
Along with Development of Multimedia Technology, digital camera, mobile phone digital camera and video camera more and more are consumers in general's favor, when people's logarithmic code camera, mobile phone digital camera and video camera are pursued miniaturization, its quality of image of shooting object is also proposed higher requirement, the image frame of promptly wishing shot object is clear, and the image quality of object depends on the quality of each optical module in the digital camera to a great extent.
Aspherical lens is optical module indispensable in the digital camera, and existing digital camera aspherical lens is generally made by the model method.During the eyeglass mold forming, owing to consider the factors such as difficulty of shaping shrinkability, the control of conveniently stripped and preform volume, so select big slightly preform, the eyeglass external diameter was often greater than required external diameter after modeling glass lens was shaped, use the anchor clamps clipped lens again, redundance is ground off by emery wheel.
A kind of existing lens machining device is consulted Fig. 1, and this lens machining device comprises one first chuck 11, one second chuck 12 and an emery wheel 13.Eyeglass 14 comprises aspheric curve 141 and aspheric curve 142.This first chuck comprises three claws 110 (cut open for rotation among the figure, only show two), and this second chuck 12 comprises three claws 120.By the protruding outer rim clipped lens of aspheric curve 141 and aspheric curve 142, the circle that three claws 110 surround cooperates with the edge surface of aspheric curve 141 respectively for claw 110 and claw 120, and the circle that three claws 120 are surrounded cooperates with the edge surface of aspheric curve 142.The shortcoming of this anchor clamps is: the aspherical shape of different eyeglasses needs the anchor clamps of different size, causes the anchor clamps type too much, has increased cost; Claw 110 partly contacts with aspheric surface with claw 120, will damage be arranged to the eyeglass working surface; When the final required external diameter of eyeglass was very little, the anchor clamps manufacture difficulty obviously increased, and also difficulty comparatively during clamping; The difficult location of two chucks during the anchor clamps clamping is easy to generate off-centre after causing eyeglass via wheel grinding.
In view of this, be necessary to provide that a kind of clamping is convenient, the seriation degree is higher and eccentric less anchor clamps, thereby obtain the eyeglass that manufacturing accuracy is higher, production cost is lower.
[summary of the invention]
The object of the present invention is to provide a kind of eyeglass, this eyeglass precision is higher, eyeglass working surface quality is higher, and production cost is lower.
Another object of the present invention is to provide a kind of method of machining lens, this method is simple to operate.
Another purpose of the present invention is to provide a kind of lens machining device, and the anchor clamps clamping of this device is convenient, the seriation degree is higher and eccentric less.
Eyeglass of the present invention is a molded glass lens, it comprise two can be inequality aspheric curve and two anchor rings are installed, this install anchor ring be from non-curve face outward flange to around extend, it is annular, this two aspheric curve lays respectively at the both sides of eyeglass, on this two installations anchor ring a recess is arranged respectively.
Lens machining device of the present invention comprises two chucks and an emery wheel.This chuck comprises three claws, and it evenly distributes, and a projection is arranged at the claw top, and the size of this projection, shape cooperate with the recess of above-mentioned eyeglass; Emery wheel is used for the above-mentioned eyeglass of grinding dressing.
Eyeglass job operation of the present invention may further comprise the steps: above-mentioned eyeglass and above-mentioned lens machining device are provided, eyeglass are placed between two chucks, and hold, the edge of emery wheel contacts with lens edge, and revolving wheel and chuck are about to the eyeglass redundance and grind off.
Compare prior art, eyeglass of the present invention comprises a recess, is convenient to clipped lens, makes that the eyeglass precision is higher, mirror-quality is higher, the anchor clamps clamping of this lens machining device is convenient, the seriation degree is higher and eccentric less, so this eyeglass job operation makes production cost lower.

[embodiment]
See also Fig. 2 and Fig. 3, this eyeglass 24 is a molded glass lens, and it comprises first surface 241 and second surface 244.This first surface 241 comprises an aspheric curve 242 and an installation anchor ring 243, and this aspheric curve 242 is in first surface 241 centers, and this installs anchor ring 243 is annular, and it is positioned at first surface 241 peripheries, joins with aspheric curve 242; This second surface 244 comprises an aspheric curve 245 and an installation anchor ring 246, this aspheric curve 245 is in first surface 244 centers, this installs anchor ring 246 is annular, it is positioned at first surface 244 peripheries, join with aspheric curve 245, on this two installations anchor ring 243,246 recess 240,247 is arranged respectively, this two recess 240,247 is symmetrically distributed.
This lens machining device comprises two chucks 21 and an emery wheel 23.This chuck 21 comprises three claws 210 and a right cylinder 212, this three claw 210 forms for the end face from right cylinder 212 extends, it is uniformly distributed in the circumferential edges of right cylinder 212 end faces, one projection 211 is arranged at claw 210 tops, and the size of this projection 211, shape cooperate with the recess 240 of above-mentioned eyeglass 24; Emery wheel 3 is used for the above-mentioned eyeglass 24 of grinding; This emery wheel 23 is cylindrical.
When processing above-mentioned eyeglass 24, above-mentioned two chucks 21 are staggered relatively, make its claw 210 face-to-face, eyeglass 24 is placed between this two chuck 21, two chucks 21 cooperate with two recess 240,247 of eyeglass respectively by the projection 211 that claw 210 holds eyeglass 24, two chucks 21, and the edge of the face of cylinder of above-mentioned emery wheel 23 and eyeglass 24 is circumscribed, rotary chuck 21 and emery wheel 23 can grind off the redundance of eyeglass 24.
