Abstract
The invention discloses a shape machining method of cover plate glass of a touch screen. The method comprises the following steps of: overlapping a plurality of pieces of small glass and cutting; increasing protection glass with the same size above and below the small glass; fixing on a machining table to carry out contour machining; after the machining is finished, forming blank glass with the shape which is the same as that of model glass; and carrying out CNC (Computerized Numerical Control) fine machining and CNC fine machining beveling machining on the blank glass to be machined into a cover plate glass finished product. The machining efficiency is greatly improved and the machining cost of one piece is reduced by more than 30%, so that the bottleneck problem of machining the cover plate glass of the touch screen is relieved.
Description
Technical field
The present invention relates to a kind of touch-screen cover-plate glass, particularly a kind of contour processing method of cover-plate glass.
Background technology
Cover-plate glass is one of major parts of touch-screen, and its physical dimension tolerance is controlled at ± 0.05mm; Strength test, static pressure test requirement 〉=500Mpa, the steel ball drop test requires 113g/30cm (falling twice).Because very high to requirement of strength whole behind the precision of physical dimension, the tempering, very high to the equipment and process technical requirements so manufacturing procedure is complicated, this has also limited the lifting of each touch-screen producer production capacity to a great extent.
At present, the method of cover-plate glass physical dimension processing is mainly, a large glass substrate cuts into the small pieces of fixed measure by emery wheel, carry out roughing by CNC1 and become blank, become work in-process by the CNC2 retrofit again, clear off the chamfering finished product by CNC3 more at last, size and precision by three CNC process to guarantee cover-plate glass require glass edge to want the smooth smooth tiny crackle that do not have simultaneously.Owing to need three CNC processing, and each every axle can only process a slice, so efficient is very low, cost is higher.
Summary of the invention
Technical problem to be solved by this invention is: a kind of new cover-plate glass contour processing method is provided, and it is the longest to improve spended time, and the roughing operation that processing charges is the highest improves the efficient of processing, thereby alleviates the bottleneck problem of touch-screen cover-plate glass processing.
For achieving the above object, the present invention takes following technical scheme, and a kind of touch-screen cover-plate glass contour processing method is characterized in that:
1) will open greatly the square little sheet glass that glass substrate cuts into fixed measure, the size of little sheet glass is decided according to the size of product to be processed;
2) make protective glass, its physical dimension and small pieces glassy phase are together;
3) the little sheet glass of multi-disc is superimposed, top and bottom respectively increase a slice protective glass and are fixed on the processing frame, form to be processed group;
4) analogue formation glass, its physical dimension is than the monolateral large 0.2-0.4mm of cover-plate glass finished product physical dimension;
5) copying is to be processed group, and is identical with model glass profile to its profile, and than the monolateral large 0.2-0.4mm of cover-plate glass finished product physical dimension;
6) carry out CNC precision work and form the cover-plate glass work in-process, to be processed group after step 5 processing by precision work, formation cover-plate glass work in-process make the work in-process profile than the monolateral large 0.1mm of finished product profile;
7) carry out CNC precision work bevelling, finish the cover-plate glass sharp processing.
The invention has the advantages that, utilize lower-cost grinding wheel, multi-disc simultaneously copying becomes blank, greatly reduces the cost of three CNC processing of conventional one-piece, and efficient improves decades of times.
Embodiment
The invention will be further described below in conjunction with embodiment; a preferred embodiment of the present invention is; a kind of contour processing method of touch-screen cover-plate glass; be about to a large glass substrate and cut into suitable little sheet glass; many pieces little sheet glass are superimposed, and unidimensional protective glass of Ge Jia forms one to be processed group up and down.Analogue formation glass, its physical dimension is than the monolateral large 0.3mm of cover-plate glass finished product physical dimension; On copying equipment; to be processed group with glass to be processed and protective glass composition is fixed in the upper lower fixed disk; model glass is fixed on other one group of shaft collar; carry out copying; copying is divided into processing stations and model station; the vertical rotation axis of processing stations and model station is done at the uniform velocity rotation by two synchronous electric motor driving respectively, thereby drives to be processed group and model glass synchronous rotary.Connect motor on the processing stations transverse axis, drive grinding wheel during work and do high speed rotating.On the thimble retaining plate thimble is installed on the model station.The cut point of grinding wheel, the summit of thimble, to be processed group central point, the central point of model glass are on the same horizontal plane all the time, and parallel in twos.During work, level of synchronization is near to be processed group and model glass under the effect of spring force for horizontal rotating shaft and thimble retaining plate, and to be processed group and model glass are done at the uniform velocity rotation under the drive of two vertical rotation axis.The grinding wheel of high speed rotating cuts to be processed group of edge and polishes.Thimble slides along with the model glass edge, guaranteed the abrasive cut-off wheel cut point to the distance of group switching centre point to be processed all the time with the thimble summit to model center of glass point apart from just as.Machine rear to be processed group of monnolithic case and model glassy phase together, and than the monolateral large 0.3mm of cover-plate glass finished product physical dimension.
Be called blank by the sheet glass behind the copying, blank is finish-machined to work in-process through CNC, and the work in-process profile is than the monolateral large 0.1mm of finished product profile, carries out at last CNC and clears off bevelling and be processed into the cover-plate glass finished product.
The small pieces glass multi-disc that cuts is superimposed, carries out roughing by the mode of copying with grinding wheel, thereby form blank, and then be finish-machined to work in-process with the CNC monolithic, clear off bevelling by CNC more at last and become the cover-plate glass finished product.This touch-screen cover-plate glass contour processing method, compare with common practice of the same trade, it is the longest to have improved spended time, the roughing operation that processing charges is the highest, mode with multi-disc stack grinding wheel copying, greatly improved the efficient of processing, the monolithic decrease machining cost is more than 30%, thereby alleviated the bottleneck problem of touch-screen cover-plate glass processing.
