Example 4
As shown in fig. 5, 6 and 7, the present embodiment provides a process for manufacturing a vehicle glass with a barcode, including: the vehicle glass is used as a front windshield and comprises a first glass 101, a second glass 102 and an intermediate film 103 arranged between the first glass 101 and the second glass 102, wherein the first glass is provided with a first surface 1011 facing the outside of a vehicle and a second surface 1012 adhered with the intermediate film; the second glass has a third surface 1021 adhered to the interlayer film and a fourth surface 1022 facing the vehicle interior; the preparation process comprises the following steps:
first, a first glass 101 and a second glass 102 are provided;
secondly, shielding layers 21 and 22 are printed on the second surface 1012 and/or the fourth surface 1022, and the material of the shielding layers can be selected from an ink layer;
then, a bar code 105 is formed on the second surface 1012 and/or the fourth surface 1022 by laser etching corresponding to the position of the shielding layers 21, 22, the bar code including unique information of glass and/or vehicle;
then, the first glass 101 and the second glass 102 are molded or self-weight-formed in a hot bending furnace;
finally, an interlayer film 103 is sandwiched between the first glass and the second glass that are hot-roll formed.
Specifically, the step of forming the bar code by laser etching includes: by adopting the fiber laser, the fiber laser does not react with the glass, so that the glass material can be prevented from being removed. The diameter of the circular light spot of the laser is 0.03mm, the wavelength can be selected to be 1064nm, the power of the laser can be selected to be 42W, the frequency can be 650KHz, and the etching speed can be selected to be 4000 mm/s. The laser-etched locations can be laser-etched to remove portions of the masking layer (ink layer) at designated locations in the printed area of the windshield, preferably in the middle region of the masking layer 22, to create a frosted white background effect, which in combination with the remaining ink layer in the etched areas creates a bar code. Generally, the transparency (transparency) of the transparent region of the front windshield is generally higher than 75%, and the frosted effect can reduce the transparency by at least 10%, preferably by 30-50%. Generally, the surface roughness Ra of the glass before laser etching is about 0.01, and after laser etching, the surface roughness Ra of the bar code with frosted effect of the exposed white background on the glass is between 0.1 and 0.8, namely, the roughness of the white background area of the bar code formed after the local shielding layer is removed through laser etching is increased, and the transparency is reduced.
Since laser etching requires a high focal length, it is necessary to adjust the height position of the laser head before laser etching each glass sheet. For the laser etching bar code of the curved glass, a laser head can be arranged at the end part of a manipulator, the distance measurement is carried out in real time through the laser, and the posture correction is carried out through the end part of the manipulator, so that the profile fluctuation of the curved glass is overcome, and the accurate focal length is kept.
In order to keep the depth consistency of bar codes formed by laser etching and ensure the color consistency of frosted white bottom, the laser head is opposite to the normal direction of the curved glass as far as possible, and the specific process comprises the following steps: the red light square pattern projected on the surface of the glass in advance is consistent with the size and the carved position of the carving code, for a new variety or a new batch of glass products, whether the projected red light pattern is square or not can be measured, if the length and the width are inconsistent, the laser head can be judged not to be in the normal direction of the etched curved surface, and the posture of the laser head is readjusted until the red light pattern is square.
Since the laser focal length and the object distance deviation can etch the etched surface within the range of plus or minus 0.5mm, namely, the laser etching can be realized within the focusing error range of h being 1mm, taking the front curved glass with a plurality of curvature radiuses as an example, the front curved glass can comprise a profile with the curvature radius of 50mm, a profile with the curvature radius of 200mm and even a profile with the curvature radius gradually changing from 50mm to 200 mm. Taking a glass mold surface with a curvature radius R of 200mm as an example, a two-dimensional code is formed on the glass mold surface by laser etching, and as shown by the graph size shown in fig. 8 and calculated by combining a trigonometric function, L is 39.95mm, which is about 40mm, that is, the maximum size of the obtained laser-etched barcode is about 40mm × 40 mm.
Further, the barcode of this embodiment is preferably a two-dimensional code, which is square, and the size of the two-dimensional code may be 12mm × 12mm, and is located in the shielding layer region corresponding to the second long side of the front windshield, that is, in the black edge (lower side shielding layer) region of the large head at the bottom of the windshield, and is preferably located in the central region of the shielding layer. The height h of the big head black edge is about 30 mm-200 mm, and preferably, the distance d between the two-dimensional code and the upper edge (from the big head black edge) of the shielding layer area corresponding to the second long edge is 5 mm-30 mm. If d is too small (less than 5mm), the shielding area to be subjected to laser etching is too close to the glass transparent area, so that the two-dimensional code formed by laser etching and the surrounding shielding layer form certain contrast, and tools such as a scanning gun, a mobile phone and the like are not facilitated to quickly and effectively identify the two-dimensional code; if d is too large (exceeding 30mm), that is, the margin of the shielding area to be laser-etched from the lower edge of the second long side of the glass is insufficient, then it is generally necessary to reserve a part of the peripheral edge of the glass to be embedded into the vehicle body or surrounded by the vehicle body trim when the windshield is mounted on the vehicle, and too large d may cause a part of the pattern of the two-dimensional code to be shielded, which may result in failure of two-dimensional code recognition, so d is preferably between 5mm and 30 mm.
In this embodiment, since the bar code is formed only on the fourth surface by laser etching, a step of pre-sintering the first glass and/or the second glass is not required before the interlayer film is sandwiched between the first glass and the second glass, and thus the process flow of manufacturing the vehicle glass with the bar code can be shortened. When the shielding layer is arranged on the fourth surface, the bar code formed on the shielding layer has a frosted white bottom when being observed from the outside of the vehicle, and the color of an object (such as a center console) in the vehicle is shielded, so that the contrast of the bar code is improved, and the bar code can be effectively identified conveniently. And when the bar code is formed on the second surface by laser etching or the bar code is formed on the second surface and the fourth surface by laser etching, the step of pre-sintering the first glass and/or the second glass is needed before the interlayer film is sandwiched between the first glass and the second glass, so that the ink layer is pre-sintered and cured on the surface of the glass, the defect of the process caused by the fact that the ink layer is not dried and splashed in the laser etching process is avoided, and the performance and the stability of the glass are ensured. When the shielding layers are arranged on the second surface and the fourth surface, the bar code arranged on the shielding layer on the second surface has a frosted white bottom when being observed from the outside of the vehicle, the color of the shielding layer on the fourth surface is shielded, the black-white contrast of the bar code is improved, and the bar code can be effectively identified; and from the inside observation of vehicle, the bar code that sets up on the shielding layer on the fourth surface has dull polish white end, plays the shielding effect to the shielding layer colour on the second surface, has improved the black and white contrast of bar code, so the effective recognition that can be obtained of bar code of being convenient for. It is easy to understand that, when the shielding layer is only disposed on the second surface and the shielding layer is not disposed on the fourth surface, the barcode formed on the shielding layer has a frosted white background when viewed from the outside of the vehicle, so as to shield the color of an object (such as a console) inside the vehicle, thereby improving the contrast of the barcode, and thus facilitating the barcode to be effectively identified.
It should be added that in this embodiment, a bar code 105 is formed on the second surface 1012 and/or the fourth surface 1022 by laser etching, where the bar code includes unique information of glass and/or a vehicle; then, the first glass 101 and the second glass 102 are subjected to compression molding in a hot bending furnace; in the actual manufacturing process, the first glass 101 and the second glass 102 may be first molded in a hot bending furnace, and then the bar code 105 may be formed on the second surface 1012 and/or the fourth surface 1022 by laser etching. It is understood that the present embodiment provides a process for manufacturing vehicle glass with bar codes, wherein the process step of forming bar codes by laser etching can be performed before the pressing in the hot bending furnace, i.e. on flat glass for example, or after the pressing in the hot bending furnace, i.e. on curved glass for example.
In summary, the preparation process of the vehicle glass with the bar code provided by the invention is not only suitable for manufacturing the bar code of the curved glass, but also suitable for manufacturing the bar code of the plane glass. When the laser head is used for manufacturing bar codes on plane glass, the normal direction of the laser head facing the glass is easier to realize, and the operation is simpler and more convenient. Compared with the prior art, the invention overcomes the defects of traditional transfer printing, silk screen printing and the like, and can realize that the bar code obtained by each laser etching is unique or can be customized.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
