Abstract

A cutting apparatus for plastic lenses is disclosed. A machine main body driven by the driving source and sliding toward the first direction is disposed on the first sliding rail of the rack. A positioning jig driven by the driving source and for raising and shifting toward the second direction and a cutting mechanism capable of opening/closing and shifting toward the second direction are disposed on the machine main body respectively. A cam rack having symmetrical cam slots and driven by the driving source are set to the fastening rack of the cutting mechanism, and the cutting mechanism includes the upper guiding plate having the upper knife and the lower guiding plate having the lower knife, which are respectively disposed into the symmetrical cam slots of the cam rack through the rollers, so that when the driving source drives the cam rack for operation, the upper knife of the upper guiding plate and the lower knife of the lower guiding plate are driven to perform closing and opening actions to cut the plastic lenses. Accordingly, by utilizing the curve design of the cam slots of the cam rack, when the upper and lower knives cut the lenses, the shift of the relative motion is rapidly performed in advance. While approaching the cutting potion, the cut of the relative motion is slowly down. The inertia of the motion is efficiently reduced and the well motion is therefore obtained.

OBJECTS OF THE INVENTION · Technical Fields of the Invention The present invention particularly provides a multi-segment shifting relative to a U-transfer and a good motion domain when the undercut cutter of the cam groove is provided. The lion strips are effectively reduced [previous technology], press, plastic lenses have been widely used in mobile phones or digital phase plastic lenses are made by means of mold injection molding n^, = lens, f film or many wash lanes Or the scrap formed by the flow channel, the lens must be moved to the shearing plate 1 3 before the assembly of the cutting blade. 4, on the template! 3 舆 虹 虹 KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS KS It can be used for fixing the lens on the lens.

After 3, move up until the next: 1 = 1 cut ί make ^ 上 · ^ knife 11 contact. After the cutting is completed, the pressure cylinder is opened = ci4 drives the upper and lower cutters to hit 1,284,805. The inertia 'this inertia will cause the upper cutting point' and the lower template 14 drives the shearing edge of the lower cutter 22 to be connected with the upper cutter ii. The moment that the lens is cut off is up to the upper knife 1, and it is easy to reduce the life of the cutter. 2 impact also, * this shearing device with good motion characteristics, the upper and lower cutter Sun Yansheng from the speed = short displacement movement time, when approaching the lens position, the good movement 'to accurately and effectively cut, However, the source of the good, == to the shortcomings of the formula. And the financial market ~ (four) contention, this can effectively improve the [invention] The fixed system provides a kind of plastic lens cutting device, which is "Ξ 凸 convex = said as the driving source to drive the front and rear pressure cylinder convex 'roll Γ Γ Γ In the symmetrical cam groove of the cam plate frame, when the upper, the rear and the rear linear sliding action are actuated, the opening and closing movement of the upper and lower guide plates by the convex dry plate can be driven to cut the plastic lens; , Hi's curve design, can make the operation of the pressure as a driving source, and achieve the purpose of the market. The frame of the plate provides a shearing device for the plastic lens, and the cam is fast; the design of the military is to enable the upper and lower cutters to cut the lens first, then to shorten the displacement movement. The time, close to the cutting part can be obtained [dynamic shearing] with precise and effective cutting lens into the fresh miscellaneous supply - _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ When the upper and lower cutters are close to the cutting part, 1284085 ίίίί==cutting the lens 'not only can accurately and effectively cut the lens, but also the inertia of the movement can effectively ensure the life of the cutter.
