Abstract
The invention relates to the field of processing of planar wafer optical parts, in particular to a float disc feeding method for planar wafer optical parts. The float disc feeding method includes the steps: firstly, covering lens paper on adhesion surfaces of planar wafer optical parts to be processed, further smearing diluted shellac on the adhesion surfaces and drying the adhesion surfaces for standby application; secondly, uniformly smearing a layer of castor oil on an adhesion film, leading the surfaces, which are covered with the lens paper and dried for standby application, of the planar wafer optical parts to face the adhesion film, placing the surfaces on the adhesion film smeared with the castor oil, and reserving a gap between each two adjacent planar wafer optical parts; and finally, filling hot melt adhesive in the gaps among the planar wafer optical parts. The float disc feeding method has the advantages that deformation of surfaces of the planar wafer optical parts caused by cure shrinkage of the hot melt adhesive is prevented, consumption of the adhesive is reduced, the optical parts are firmly adhered, pressure on the parts is uniformly distributed effectively during processing, and breakage of the parts is avoided during processing.
Description
Technical field
The present invention relates to plane lamina optical element processing technique field, be specifically related to a kind of plane lamina optical element float glass process disc loading method.
Background technology
The whole manufacturing process of optical element is a process of lapping; Be to utilize special mechanical main shaft to drive corresponding lap and the fixing bonding mould that needs processing parts, and add special-purpose abrasive material and the need processing parts is rotated each other and drive jib and do the grinding manufacturing that whole plane lamina is accomplished in certain swing at mould and part to be processed surface.
If the plane lamina optical element of small-medium size adopts single-piece work, usually, cause the surperficial surface precision that processes to be difficult to control, and the efficient of processing is also very low because undersized.So, for this type part, often do not adopt the form of single-piece work, and be to use PUR that a plurality of plane lamina occasional combinations are bonded on the bonding mould, form a bigger part mirror mould.So both helped the control of optical element surface type, can the efficient of processing have been improved greatly again.
The optics processing industry often adopts the PUR of hot melt to realize so interim bonding at present.And PUR the shrinkage character behind the intrinsic cooling curing, can make the surface configuration of optical element that variation to a certain degree takes place.This variation is in the recovery that machines, PUR can nature after having removed, thereby changes the surface configuration that processed originally, and it is particularly serious that this variation shows on thin optical element, usually causes the surface type index of product defective.Simultaneously, because part is that rigidity contacts with the bonding mould, the pressure that in process, receives is inhomogeneous, is easy to let the part breakage scrap, and causes material and artificial loss.
Summary of the invention
In order to overcome existing above-mentioned deficiency in the prior art, the invention provides following technical scheme:
A kind of plane lamina optical element float glass process disc loading method said method comprising the steps of:
At first, on the adhesive surface of plane lamina optical element to be processed, cover lens paper, be coated with again and spread shellac, dry for use.Shellac is claimed shellac or shellac again, and certain adhesion strength is arranged itself, and shellac can permeate lens paper; After the oven dry; Lens paper and plane lamina optical element are close together, and shellac toughness is not strong, is easy to fragmentation; After the plane lamina optical element machines, be easy to remove the shellac above the part.
Then, on the bonding mould, evenly smear one deck castor oil, the plane lamina optical element that said oven dry is for use is coated with the one side of lens paper towards the bonding mould, is placed on the bonding mould of having smeared castor oil, and between the plane lamina optical element, reserves the space.The castor oil of on the bonding mould, smearing has well absorbed the distortional stress of part as the flexible mat of one deck band, and the pressure that part receives in the time of will grinding part simultaneously scatter uniformly.Can effectively reduce part bonding distortion like this, overcome and used the bonding mould bonding force that the contraction during because of adhesive cures causes in the process of bonding plane lamina optical element in existing plane inhomogeneous, improve the surface type machining accuracy of optical element.Because the pressure that part receives is by effective homogenising, so avoided the fragmentation of part in the process basically.
At last, PUR is filled in the gap between the said plane lamina optical element, treat glue cooling after, optical element just is fixed on the bonding mould, so just can begin the processing optical part.Like this PUR only with the side of plane lamina optical element to be processed bonding, bond area is little, the stress deformation of the plane lamina optical element to be processed surface generation that has so just reduced to bring behind the PUR cooling curing.And the mirror disk of producing is more convenient during lower wall again, and glue consumption is few, saves production cost.
Preferably, said plane lamina optical element float glass process disc loading method, PUR is filled in the gap between the plane lamina optics after, PUR is heated up melts, to guarantee to be filled in the PUR and the part side bonds well of gap.Preferred, use flatiron with ironing of PUR.
Preferably, in the described plane lamina optical element float glass process disc loading method, on the adhesive surface of plane lamina optical element to be processed, cover two-layer lens paper.The lens paper quality is soft, be easy to protect the optical element plane that is covered, but the lens paper number of plies too much can consume more shellac, crosses can not play a protective role at least, so the number of plies of lens paper is with two-layer comparatively suitable.
Compared with prior art, beneficial effect of the present invention:
1, reduced the bond area of PUR and plane lamina optical element, thereby reduced the distortion that the PUR cure shrinkage causes plane lamina optical element surface, the qualification rate of the surface type of the plane lamina optical element that has guaranteed to process.
2, avoided the plane lamina optical element to contact with the direct rigidity in bonding mould surface, the effective homogenising of pressure quilt that part is received has been avoided the fragmentation of part in the process basically.
3, realized that farthest glue consumption can guarantee optical element and the firm purpose of bonding mould bonding less again.

At first, on the adhesive surface of plane lamina optical element 4 to be processed, cover two-layer lens paper 3, be coated with again and spread shellac, dry for use;
Then; On bonding mould 1, evenly smear one deck castor oil 2; The plane lamina optical element that said oven dry is for use is coated with the one side of lens paper towards the bonding mould, is placed on the bonding mould 1 of having smeared castor oil 2, and between the plane lamina optical element, reserves the space;
At last, PUR 5 is filled in the gap between the said plane lamina optical element.PUR may cool off in the filling process, at this moment uses flatiron with the ironing once more of the PUR around the part, to guarantee PUR and part side bonds well.After the cooling, just can begin the processing optical part.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
