Description
Technical field
The present invention relates to a kind of shear of glass lens, be particularly related to a kind of curve design that utilizes cam path, can make upper and lower cutting knife when shearing eyeglass, can do the relative motion of multistage speed change, and then effectively reduce motional inertia and obtain the shear of the glass lens of good kinetic characteristic.
Background technology
Glass lens has been widely used in the photograph camera lens of mobile phone or digital camera, glass lens is to make in the mode of mould ejection formation, therefore behind the ejection formation, on the glass lens or many running channels or the formed leftover pieces of runner are arranged, so glass lens must be earlier through shearing the program of leftover pieces before assembling with lens barrel, can carry out next operation procedure, and shear the program of leftover pieces, then be that the eyeglass dislocation is carried out operation on cutter.
See also Fig. 1, it is to be No. 93100886 patent case of Taiwan application for a patent for invention, described shear is that upper and lower cutting knife 11,12 is installed in respectively on the upper and lower template 13,14, cope match-plate pattern 13 also is connected with the piston rod of pressure cylinder 10, lower bolster 14 then is connected with the cylinder body of pressure cylinder 10, guide pillar 15 is for precision positioning and guides upper and lower template 13,14 can slide suitable upper and lower moving in addition, bearing fixed head 16 is provided with eyeglass bearing 17 in addition, can put for eyeglass 18 levels, be beneficial to and shear operation.
See also Fig. 1,2, when pressure cylinder 10 shrinks, it will drive cope match-plate pattern 13 declines, contact up to the shearing point of upper cutter 11 with eyeglass 18 edges, promptly stop start, and finish preliminary location; See also Fig. 1,3, then, lower bolster 14 moves up behind cope match-plate pattern 13, finishes to the shear action of eyeglass 18 and with upper cutter 11 contacting up to lower cutter 12.After shearing was finished, pressure cylinder 10 was released, and upper and lower template 13,14 drives upper and lower cutting knife 11,12 and opens, and promptly finishes the operation of shearing.
Described shear is owing to be as drive source with pressure cylinder 10, and the kinetic characteristics of pressure cylinder 10 itself are the acceleration and deceleration motions that rises sharply and die-off in initial point and terminal point, therefore when pressure cylinder 10 contractions make upper cutter 11 contact with the shearing point at eyeglass 18 edges, it also can't be issued to fully in fast state at once and stop, but can produce a motional inertia, this motional inertia just can cause upper cutter 11 to strike the shearing point at eyeglass 18 edges, and when lower bolster 14 drives lower cutter 12 risings to eyeglass 18 shearings, be to shear with relative high-speed motion, not only be unfavorable for shearing, and the moment of cutting off eyeglass is when contacting with upper cutter 11, its motional inertia also can cause lower cutter 12 to strike upper cutter 11, and the service life of very easily reducing cutting knife.
So shear with good kinetic characteristic, on it, lower cutter is a Ying Xianzuo displacement movement fast, to shorten the time of displacement movement, when near lens position, work shearing motion at a slow speed then must slow down, precisely effectively shearing, yet, described good kinetic characteristic be simple pressure cylinder can't reach, adopt servo motor collocation screw rod group if change, then significantly improve the cost of equipment again, cause reducing the competitiveness in market, therefore if still can be with cylinder pressure as drive source, arrange in pairs or groups the again design of mechanism, not only can reach and have good kinetic characteristic, and possess the competitiveness in market, this can effectively improve existing scarce fraud.
Summary of the invention
Main purpose of the present invention provides a kind of shear of glass lens, it is to set up a cam grillage that has the symmetrical cam groove and can be driven as drive source by cylinder pressure with fixed mount, other is installed with the upper guide plate of upper cutter and is installed with the bottom guide of lower cutter, then be located in the symmetrical cam groove of cam grillage with turning rolls respectively, when making the start of cylinder pressure driving cam grillage, can drive upper and lower cutting knife on the upper and lower guide plate and make the opening and closing movement of relative direction, to shear glass lens; By this, utilize the curve design of the cam path of cam grillage, in the time of can making with cylinder pressure as drive source, still can obtain good kinetic characteristic, and reach the purpose that promotes the market competitiveness.
An of the present invention purpose provides a kind of shear of glass lens, the curve design of the cam path of its cam grillage, be to make upper and lower cutting knife when shearing eyeglass, do relative motion displacement fast earlier, to shorten the time of displacement movement, near the shearing position time, the shearing of doing relative motion at a slow speed again, shear eyeglass with precisely effective, and then can obtain good kinetic characteristic.
Another object of the present invention provides a kind of shear of glass lens, the curve design of the cam path of its cam grillage, be to make upper and lower cutting knife in the time near the shearing position, with speed slowly eyeglass is sheared, not only can precisely effectively shear eyeglass, and can significantly reduce the inertia of motion and then the service life that can effectively guarantee cutting knife.
