Description

A kind of tool of rolling round glasses

[technical field]

The present invention relates to the eyeglass manufacture field, especially about a kind of tool that is used for the round as a ball processing of eyeglass.

[background technology]

Along with science and technology development, the application of various optical lenses obtains continuing to enlarge; Accordingly, for meeting the need of market, the technology of optical mirror slip production is also improved constantly.

For the preparation of circular eyeglass, generally be with shape cutting machine master slice to be cut into the square glass eyeglass earlier; Use the rounding machine with square eyeglass rounding again.But in the process of rounding, if the machining lens of single monolithic, then working (machining) efficiency is low excessively.Therefore prior art remove four jiaos and become circular method, generally be earlier a plurality of eyeglasses to be fit together, and then grind with emery wheel.

See also Fig. 1 and Fig. 2, the round as a ball process of prior art eyeglass is, after at first a plurality of square eyeglasses 1 being overlapped into eyeglass cylinder 10, the V-shaped groove 2 of again this eyeglass cylinder 10 being put into tool 30 is also fixing, be in the outer eyeglass part of tool with abrasion wheel grinding then, eyeglass cylinder after will grinding again takes off puts into another tool, continues eyeglass is worn into circle.

Because when grinding, emery wheel can produce shearing force, so eyeglass cylinder 10 need fix when grinding, and causes yield to descend to avoid eyeglass to break away from tool.The method of prior art fixing len cylinder 10 mostly is coating UV glue (ultraviolet hardening adhesive) on the V-shaped groove 2 and between each eyeglass, and the eyeglass cylinder is sticked on the V-shaped groove 2.Yet this kind method needs UV glue is removed after eyeglass processes, could be with eyeglass from V-shaped groove 2 separately.Removing the method for UV glue, generally is to adopt hydrolysis method to make UV glue lose viscosity, and required time of hydrolysis is longer, can increase the time of eyeglass processing then; And the eyeglass cylinder of hydrolysis, hydrolyzate also are easy to remain on the eyeglass, if when also will be again grinding to carry out the other end with the UV glue bond, then bonding quality descends easily, and it is fixing that eyeglass is difficult for again.

Therefore, be necessary to provide a kind of tool and method that is easy to the rolling round glasses of fixing len.

[specific embodiment]

Be described in further details below in conjunction with the tool of drawings and Examples rolling round glasses.

Please together referring to Fig. 3 to Fig. 5, the tool 100 of the rolling round glasses of first embodiment of the invention comprises a body 101; The groove (not indicating among the figure) that has two ends to run through in this body 101; Be filled with a capillary structure 102 in this groove; Offer a roughly V-shaped groove 103 on the top of this capillary structure 102, make this capillary structure 102 have inclined-plane 105,106, from vertical (being length direction), this groove 103 runs through two end faces (indicating among the figure) of this capillary structure 102; These capillary structure 102 surfaces are provided with a hermetically-sealed construction 107, the capillary structure 102 of sealing structure 107 coverings except that inclined-plane 105,106 is in the surface outside the body 101, it is used to prevent that this tool 100 from leaking gas when bleeding, specific requirement is that it can resist the pressure that produces when vacuumizing, and sealing structure 107 can be coating and applies the coating that forms.In addition, also be provided with at least one suction hole 104 on the described hermetically-sealed construction 107, this suction hole 104 is connected with capillary structure 102, and may extend to this capillary structure 102 inside, it is used for linking to each other with outside vaccum-pumping equipment, and this suction hole 104 also can be located at the optional position of these body 101 sides; Faster for capillary structure 102 inside are vacuumized, this suction hole 104 also can be established a plurality of.

These capillary structure 102 inside have the hole that is interconnected, and this hole that is interconnected also is connected with suction hole 104.The material of this capillary structure 102 can be for having the material of bicontinuous structure (being that the hole is the open structure that is interconnected), for example, the porous material that have bicontinuous structure hole of the material of this capillary structure 102 for being formed by metal sintering, this metal can be iron, aluminium, copper, nickel and cobalt or its alloy.

The shape of this groove 103 is not limited to the V-arrangement shape among the figure, and it can be decided according to the shape of the eyeglass of required processing, matches with lens shape; For example this groove 103 also can be arc groove, U-shaped groove or other polygon groove etc.

The eyeglass cylinder is placed on this groove 103 during use, and covers this inclined-plane 105,106 because the hole of capillary structure is network-like distribution, so eyeglass on the inclined-plane 105,106 stressed can be comparatively even.Behind the air that extracts in the capillary structure 102 from suction hole 104 with vaccum-pumping equipment, make the hole of this capillary structure 102 form low-pressure area, there is pressure difference in the atmospheric pressure on itself and eyeglass cylinder top and can produces absorption affinity, therefore the eyeglass cylinder is fixed on the tool 100.

And after use,, when eyeglass will take off, only need bubbling air recovery pressure in capillary structure 102, eyeglass is eliminated because of the absorption affinity that pressure difference produces, can take off eyeglass because eyeglass is to fix with the absorption affinity that pressure difference produces; Avoid needing the extra processing procedure that removes photoresist to reach except that the glue time because of adopting UV glue to fix eyeglass.

See also Fig. 6 to Fig. 8, the tool 200 of the rolling round glasses of second embodiment of the invention comprises a body 101 '; Different with the tool 100 of first embodiment is the groove (indicating among the figure) that has two ends not run through in this body 101 '; Be filled with a capillary structure 102 ' in this groove; Offer a roughly V-shaped groove 103 ' on the top of this capillary structure 102 ', from vertical (being length direction), this groove 103 ' runs through two end faces 108 ', 109 ' of this body 101 ', and from transversely (being width), the top groove width of described groove 103 ' can be smaller or equal to the width of described capillary structure 102 '.The cell wall of the groove of tool 200 usefulness bodies 101 ' (figure does not show) matches promptly salable with this capillary structure 102 ', so capillary structure 102 ' need not to adopt extra hermetically-sealed construction to seal.

The using method of the tool 100 of described rolling round glasses comprises the steps:

Step 1, a plurality of eyeglasses are superimposed together forms the eyeglass cylinder, puts into the groove 103 of this tool 100 and makes capillary structure 102 sealings.When putting into the eyeglass cylinder, match with the inclined-plane of this groove 103 in the surface of eyeglass cylinder.

In this step 1, when eyeglass cylinder length long enough, the eyeglass cylinder gets final product the inclined-plane 105,106 of the capillary structure 102 in the complete covering groove 103; When eyeglass cylinder length is short when being not enough to cover the inclined-plane 105,106 of capillary structure 102, because the hole of capillary structure is network-like distribution, therefore also be easy to adopt other material to cover the place that the eyeglass cylinder do not cover and seal, for example can adopt the bigger adhesive plaster of intensity to paste to replenish to cover the part that the eyeglass cylinder does not cover on inclined-plane 105,106.

Step 2, the air from suction hole 104 extracts in the capillary structure 102 so that its hole hole forms low pressure, and is attracted on the groove 103 the eyeglass cylinder.When bleeding,, fit closely, so air is difficult for entering from the eyeglass joint place and influences the effect that vacuumizes thereby make between eyeglass because lens surface is comparatively smooth.

The size of the required pressure of this low pressure is decided according to the shape of eyeglass, and specific requirement is that the absorption affinity that the pressure difference between this low pressure and the atmospheric pressure produces can make eyeglass be fixed on the tool, and can be enough to overcome the shearing force that eyeglass produces when grinding.

Employing fixes eyeglass by the absorption affinity that pressure difference produces, as long as low pressure pressure is constant, the absorption affinity that eyeglass is fixed on the tool just can not changed, and therefore the power that is easy to provide enough fixes eyeglass.

Step 3 is ground this eyeglass cylinder.

Step 4 is recovered the pressure in the capillary structure 102, takes off eyeglass.

In this step 4, recovering pressure can feed gas in capillary structure 102.Because eyeglass is to fix with the absorption affinity that pressure difference produces, when eyeglass need take off, only need bubbling air recovery pressure in capillary structure 102, eyeglass is eliminated because of the absorption affinity that pressure difference produces, can take off eyeglass; Economize to remove adopt UV glue to fix the processing procedure that additionally removes photoresist that eyeglass needs, and avoid eyeglass fixing again and may have problems.Be understandable that, when the other parts of this eyeglass also need to grind, also can repeat above-mentioned four steps, continue the part that eyeglass need grind is processed.

Compared with prior art, the tool of described rolling round glasses, groove 103 are located on the capillary structure 102; In the use procedure, capillary structure 102 inclined-planes 105 in this groove 103,106 hole can form low-pressure area and Eyeglass is adsorbed on the groove 103. Process is fixed on the tool eyeglass as long as pressure difference is constant Absorption affinity just can not change, and therefore is easy to fixing len; And after machining lens is finished, press as long as eliminate Strong poorly can take off eyeglass, economize except adopting UV glue to fix the processing procedure that additionally removes photoresist that eyeglass needs, and avoid Eyeglass is fixing and issuable problem again. Therefore the tool of said implement of round lenses has the fixing len of being easy to Advantage.
