Furthermore, if the terms "first" and "second" are used for descriptive purposes only, they are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. Thus, the definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features, and "a plurality" or "a plurality" in the description of the invention means two or more unless a specific definition is explicitly provided.
The first embodiment is as follows:
the utility model provides a double-deck explosion-proof ultra-thin glass cover plate structure for folding screen cell-phone, includes ultra-thin glass 2, 2 below of ultra-thin glass are provided with first explosion-proof printing ink layer 31, first explosion-proof printing ink layer 31 lower surface is provided with printing ink frame 4, 2 tops of ultra-thin glass are provided with the explosion-proof printing ink layer 32 of second.
The first explosion-proof ink layer 31 is formed by printing explosion-proof ink on the lower surface of the ultrathin glass 2, and the second explosion-proof ink layer 32 is formed by printing explosion-proof ink on the upper surface of the ultrathin glass 2.
The ink frame 4 is printed on the lower surface of the first explosion-proof ink layer 31.
The explosion-proof ink is prepared by mixing the ink, the curing agent and the diluent according to a certain proportion, and glass cannot splash everywhere after being broken after the explosion-proof ink is printed. For example, chinese patent CN201611259798.7 discloses an explosion-proof ink. The explosion-proof ink may be a clear ink, wherein a clear explosion-proof ink is also formulated by means customary to the person skilled in the art.
Explosion-proof printing ink has certain ductility, and explosion-proof printing ink can not break away from and lead to the dislocation and produce the crease when ultra-thin glass 2 is crooked to have extra function, when display screen protection glass broke, also can not take place the glass cullet and fly off, ensure the safe in utilization of collapsible cell-phone, prevent that fingerprint membrane 1 can avoid the fingerprint to stay the surface of display screen.
The printing ink frame 4 can print various frame colors such as blue, gold, can also realize the depth of printing ink through the design of frame template and reach the texture effect, can also print different shapes and colour many times and reach color and pattern effect, and the printing ink frame 4 is used for shielding the part outside the display screen display area, has the shading effect simultaneously, and the printing ink frame 4 of different colours can be applicable to the cell-phone collocation of different colours.
The preferred second explosion-proof printing ink layer 32 top of this embodiment is provided with prevents fingerprint membrane 1, and it has been prior art to prevent fingerprint membrane 1 spraying technique, and the spraying can reduce the fingerprint in the fingerprint membrane 1 of preventing above second explosion-proof printing ink layer 32 and remain, can avoid appearing the crease when folding simultaneously.
The preferred ultra-thin glass 2 of this embodiment is ultra-thin toughened glass with a thickness of 30-100 microns, preferably ultra-thin toughened glass with a thickness of about 50 microns, and german schottky corporation in 2013 has started to supply flexible glass with a thickness of 25-100 microns in batches, the width of about 50cm and the length of hundreds of meters. In 2014, Asahi glass company of Japan made a flexible glass SPOOL with a thickness of 0.05 mm by the float method. Chinese patent CN104045221B discloses a method for preparing flexible ultra-thin glass 2.
The thickness of the first explosion-proof ink layer 31 and the second explosion-proof ink layer 32 is 30-50 microns, and the thickness of the explosion-proof ink is small, so that the protective cover plate of the ultrathin glass 2 is very thin, the light transmission is good, and the ultrathin glass is easier to fold.
In the present embodiment, the first explosion-proof ink layer 31, the second explosion-proof ink layer 32 and the ink frame 4 are preferably printed by a pad printing device.
The intaglio pad printing device is shown in fig. 2 and mainly comprises an ink chamber 54, an intaglio roller 53, a pad printing roller 52 and a jig 51, wherein the pad printing roller 52 is a rubber roller.
Taking printing of the explosion-proof ink as an example, the explosion-proof ink is placed in an ink chamber, an ink roller 55 is further arranged in the ink chamber, the ink roller 55 abuts against an intaglio roller 53, the ink roller 55 absorbs the ink in the ink chamber and transfers the ink to the intaglio of the intaglio roller 53, the intaglio roller 53 rotates along the direction a, a doctor blade 56 is arranged beside the intaglio roller 53 to scrape the ink in the intaglio roller 53, the intaglio roller 53 transfers the ink in the intaglio to the surface of a transfer printing roller 52, the transfer printing roller 52 rotates along the direction b, the ultrathin glass 2 is placed on a jig 51 and moves along the direction c, the ultrathin glass 2 passes under the transfer printing roller 52, the transfer printing roller 52 prints the explosion-proof ink on the surface of the ultrathin glass 2, the first explosion-proof ink layer 31 reaches 30-50 micrometers by repeatedly printing for 3-5 times, the printing mode of the second explosion-proof ink layer 32 is the same as the printing mode of the first explosion-proof ink layer 31, by using a repeated printing method, the second anti-explosion ink layer 32 is 30-120 microns, and the gravure pad printing device has high printing efficiency, uniform thickness and accurate thickness control.
The printing method of the ink frame 4 is the same as the explosion-proof ink printing method, and only the pattern template of the gravure cylinder 53 is different from the pattern template of the gravure cylinder 53 used for the explosion-proof ink.
Example two:
the utility model provides a double-deck explosion-proof ultra-thin glass cover plate structure for folding screen cell-phone, includes ultra-thin glass 2, 2 below of ultra-thin glass are provided with first explosion-proof printing ink layer 31, the edge of ultra-thin glass 2 is provided with printing ink frame 4, and printing ink frame 4 sets up between ultra-thin glass 2 and first explosion-proof printing ink layer 31, 2 upper surfaces of ultra-thin glass are provided with second explosion-proof printing ink layer 32.
That is, the difference between the embodiment and the first embodiment is that the positions of the ink frame 4 and the first explosion-proof ink layer 31 are exchanged, the ink frame 4 is printed on the lower surface of the ultra-thin glass 2, the ink frame 4 is printed on the edge of the ultra-thin glass 2 at this time, the ink is not present in the middle area, the explosion-proof ink is printed again, the explosion-proof ink is partially printed on the ink frame 4 at this time, and partially printed on the surface of the ultra-thin glass 2, but both are still printed by the gravure pad printing device.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
