Abstract
The invention discloses an optical scanner for the contour of a spectacle lens, and helps to solve the technical problems that a conventional optical scanner for the contour of a spectacle lens is low in scanning efficiency and high in cost. The optical scanner comprises a base plate, a sliding platform, a linear array CCD arranged on the base plate, a controller gatherer for acquiring data of the linear array CCD, and a driving mechanism for driving the sliding platform to move horizontally. A convex lens is disposed right over the linear array CCD. A lamp bead is disposed above the focus of the convex lens. A transparent glass plate is arranged on the sliding platform, and is located between the linear array CCD and the convex lens.
Description
Technical field
The present invention relates to a kind of lens profile optical scanner.
Background technology
Lens edge grinding machine is a kind of machine lens being ground shaping, has a wide range of applications in spectacles industry, and auto lens edger is by being generally made up of lens profile scanner and numerical control glasses lens edge polishing system.The function of lens profile scanner is used to determine eyeglass profile, by the outline data of eyeglass can finally worn into the scanning survey of mirror holder and eyeglass, after the parametric synthesis process such as pupil distance, the pupil of this outline data and patient are high, bridge of the nose distance, namely become the processing foundation of glasses lens edge polishing.Data after numerical control glasses lens edge polishing system utilizes these process go to drive each executive component, coordinate the grinding that its action has come lens blank.
Lens profile scanner many employings contact type probe of the automatic edging machine occurred on the market is at present measured, the method technology maturation, measuring accuracy is high, can meet the accuracy requirement of machining eyeglass, but automatic edging machine is expensive, easy to wear and the easily landing of probe, maintenance cost is high, in addition, by the impact of metering system, speed is difficult to get a promotion, and causes scan efficiency very low.
The present invention is based upon on the bases such as step motor control technology, line array CCD driving and control technology, Numeric Control Technology and image processing techniques, adopt the method for artificial placement, autoscan eyeglass, automatically generation profile, reduce cost while substantially increasing scan efficiency, simplify operation.
Summary of the invention
Technical matters to be solved by this invention is just to provide a kind of lens profile optical scanner, solves the technical matters that existing lens profile scanner scan efficiency is low and with high costs.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Lens profile optical scanner, comprise base plate, sliding platform, the line array CCD be located on base plate, the control collector gathering linear array ccd data and the driving mechanism driving sliding platform to move horizontally, convex lens are provided with directly over described line array CCD, the focus place, top of described convex lens is provided with lamp pearl, described sliding platform is provided with transparency glass plate, and described transparency glass plate is located between line array CCD and convex lens.
Further, described driving mechanism comprises stepper motor and the leading screw cooperatively interacted and screw, and described leading screw is connected with the rotating shaft of stepper motor, and described screw is fixed on sliding platform.
Further, described driving mechanism comprises for cylinder or hydraulic cylinder, and cylinder or hydraulic cylinder have piston rod, and described sliding platform is connected with the piston rod of cylinder or hydraulic cylinder, or described piston rod connects push rod, and described push rod is connected with sliding platform.
Further, described base plate is provided with pole, and described convex lens and lamp pearl are located on pole.
Further, described sliding platform is provided with fixture, described holder transparency glass plate.
Beneficial effect of the present invention is:
Transparency glass plate places lens, sliding platform is driven to drive transparency glass plate and lens to move horizontally by driving mechanism, lens is fast through line array CCD, line array CCD blocks the outline data of the light source acquisition lens of lamp pearl according to lens, outline data transfers to and controls in collector the most at last, and the whole scanning process time is short, and efficiency is high, few and the not easily loss of parts, reduces production cost and maintenance cost.
