Description
Technical field
The present invention relates to optical lens, particularly manufacturing method of vacuum upper plate of optical lens.
Background technology
Dish is to adopt the low mould of a standard on using on the optical lens at present, spread one deck demoulding cream vaseline on the low mould surface of standard, put then lens go up glue press subsequently the dish mould, the back demoulding frictioning for the treatment of that the glue solidifies, the purpose of frictioning is to make surface of the work exceed glue-line, the useful like this grinding in road down.Yet the upward dish shortcoming of making like this is a lot: 1, have one deck demoulding cream can produce misfitting of R face between lens surface and the low mould; 2, the pulling force that produces because of glue when the glue solidifies causes workpiece R face to misfit; 3, frictioning is very time-consuming; 4, coiling on that mold pressing gets on is by artificial, adds that putting lens does not have the location, position again, and last to coil the workpiece and the last dish mould that come out be not on a centre of sphere, can influence the next procedure uniformity of process time like this; 5, the more little above shortcoming of workpiece is just also outstanding.Therefore produce dish difficulty on the optical lens in batches, speed is slow, the degree of accuracy is not high, uniformity is poor.
Summary of the invention
Technical problem to be solved by this invention is, a kind of vacuum upper plate of optical lens is provided, and is used to solve on the optical lens R face and master die and misfits, and yields poorly, problem such as not easy to operate, cost height.
In order to address the above problem technical scheme of the present invention is such:
Manufacturing method of vacuum upper plate of optical lens of the present invention is meant on the technology of coiling on making and has carried out substantial change, coils by using on the production optical lenses such as demoulding cream, spreading process in the past; And the present invention makes vacuum upper plate of optical lens as follows, is different from former optical lens CD.
(1) chooses a semienclosed guide rail mechanism guide rail bracket, place a master die device, in guide rail bracket, also be placed with successively from top to bottom and coil mould, workpiece lens, grid spacer at the base of guide rail bracket.
(2) when depressing dish mould and workpiece lens, described go up dish mould and workpiece lens gummed under the effect of glue and by guide rail formation on the guide rail mechanism and master die on the unified centre of sphere.
(3) depress the veneer of dish mould and workpiece lens on the basis of step (2), the guiding by guide rail mechanism makes the R face that coils between mould, lens workpiece and the master die on a concentric shafts.
(4) take the interior air of master die device then away, the pulling force that makes it the vacuum state generation is higher with the R face goodness of fit of impelling workpiece lens and standard film, and the product R face of first-class dish can be out of shape.
The lower right side of master die has a mouth described in the above-mentioned steps (4), so that take the air in the device away, the R face of described master die is provided with the corresponding hole of R face with described workpiece lens, to reach suction-operated.The R face goodness of fit of workpiece lens and master die is that man-to-man hole by master die R face is directly to the workpiece lens vacuumizing and adsorbing, by firmly sorption workpiece lens of vacuum suction.Behind described upward dish mould and the lens gummed is by a grid spacer, makes the workpiece lens distribution of first-class dish consistent, the degree of accuracy height of making product.
The invention has the beneficial effects as follows that vacuum upper plate of optical lens is without demoulding cream, workpiece has the location, and is simple to operate without frictioning, reduced the labour, and cost is low, and output is big.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the flow chart of manufacturing method of vacuum upper plate of optical lens of the present invention;
Fig. 2 is the structural representation of an embodiment of the present invention vacuum upper plate of optical lens.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, the schematic diagram of manufacturing method of vacuum upper plate of optical lens of the present invention:
Vacuum upper plate of optical lens is made by following steps, and is simpler than the manufacture craft of coiling on the former optical lens, reliable in quality, and cost is low, and output is big, saves the labour, and efficient significantly improves.
(1) chooses a semienclosed guide rail mechanism guide rail bracket, place a master die device, in guide rail bracket, also be placed with successively from top to bottom and coil mould, workpiece lens, grid spacer at the base of guide rail bracket.
(2) when depressing dish mould and workpiece lens, described go up dish mould and workpiece lens gummed under the effect of glue and by guide rail formation on the guide rail mechanism and master die on the unified centre of sphere.
(3) depress the veneer of dish mould and workpiece lens on the basis of step (2), the guiding by guide rail mechanism makes the R face that coils between mould, lens workpiece and the master die on a concentric shafts.
(4) take the interior air of master die device then away, the pulling force that makes it the vacuum state generation is higher with the R face goodness of fit of impelling workpiece lens and standard film, and the product R face of first-class dish can be out of shape.
The lower right side of master die has a mouth described in the above-mentioned steps (4), so that take the air in the device away, the R face of described master die is provided with the corresponding hole of R face with described workpiece lens, to reach suction-operated.Behind described upward dish mould and the lens gummed is by a grid spacer, makes the workpiece lens distribution of first-class dish consistent, the degree of accuracy height of making product.
The present invention fully coincide lens workpiece and master die by the mode of vacuumizing and produces certain pulling force, the pulling force of vacuum is much larger than the pulling force of glue curing, the lens workpiece makes product relative position and uniformity fine by putting of grid spacer, largest benefit is without frictioning, technology is simple, easy to operate, reduced the labour.
