Description
Technical Field
The invention relates to the field of resin sheet coating processes, in particular to an AR coating process on a resin sheet.
Background
The resin sheet is a commonly used optical article material. The resin sheet coating is an inorganic substance (such as silicon oxide, that is, sand) coated on an organic substance (plastic). One significant difference with other coatings is that the substrate cannot be heated because the substrate is plastic and therefore the substantially stable state obtained is a room temperature condition. Further increases in temperature (or moisture absorption) cause the organic substrate to swell, while the inorganic film layer does not change much. This creates a stress between the two, which after a certain threshold is reached releases the film causing the film to tear or wrinkle.
The existing resin sheet AR coating process is characterized in that after a resin sheet is fixed through a clamp, direct coating is carried out, and coating is carried out on the back of the back surface of the resin sheet AR, but in the coating process, because the resin sheet is thin and the texture of the resin sheet is fragile, the sheet is easy to crack due to uneven force application, and the problem that the surface film of a product is cracked due to the fact that the product is easy to deform due to the change of temperature after coating is solved, so that the process is the main research direction of the application.
Disclosure of Invention
In order to solve the technical problem, the invention designs an AR coating process on a resin sheet.
The invention adopts the following technical scheme:
an AR coating process on a resin sheet comprises the following steps:
s1, slicing: adhering 77 x 0.21mm resin sheets on a UV film for fixing, cutting into 10 x 0.21mm resin sheet pieces on a special cutting machine, cooling and flushing scraps at a cutter head by continuously introducing water flow, performing linear cutting on the resin sheets during cutting, putting the resin sheet pieces on a special cleaning device for rotary cleaning after cutting, and performing debonding on the UV film by ultraviolet irradiation after cleaning to finish the whole process of cutting large-size resin sheets into small-size resin sheet pieces;
s2, film pasting: adhering a UV film on the bottom surface of the small-sized resin sheet chip, and fixing the small-sized resin sheet chip through the UV film;
s3, coating: performing AR coating on the surface of the small-sized resin sheet, and selecting SIO during AR coating2The coating power of the coating is 5kw, the Ar charging amount is 40sccm, and O2The charging rate is 50sccm, the plating rate is 1.75nm/s, Nb2O5The coating power is 4kw, the Ar charging amount is 270sccm, the plating rate is 2.1nm/s, the plating film is coated for 20nm every time, and the interval is 45 s;
s4, dispergation: performing dispergation on the UV film of the small-size resin sheet piece subjected to single-side AR coating by ultraviolet irradiation;
s5, film pouring: the small-sized resin sheet pieces are turned over, a UV film is adhered to the bottom surfaces of the turned small-sized resin sheet pieces, and the small-sized resin sheet pieces are fixed through the UV film;
s6, coating a second surface: performing AR coating on the surface of the turned small-size resin sheet, and selecting SIO during AR coating2The coating power of the coating is 5kw, the Ar charging amount is 40sccm, and O2The charging rate is 50sccm, the plating rate is 1.75nm/s, Nb2O5The coating power is 4kw, the Ar charge is 270sccm, the coating rate is 2.1nm/s, the coating is 20nm each time, and the interval is 45 s;
s7, dispergation: performing degumming on the UV film of the small-sized resin sheet piece subjected to double-sided AR coating by ultraviolet irradiation;
s8, taking and checking: and slightly taking out the small-sized resin sheet pieces subjected to double-sided AR coating by using forceps, and checking the film crack and appearance integrity under a microscope to complete the AR coating process on the whole resin sheet.
Preferably, the UV film is 5172-UV film. When coating, the UV film is needed to apply a full tensile force to the product at the lower part, thereby balancing the warping caused by coating. We therefore need to select a suitable UV film, normally a softer texture without high temperature resistance, by testing a number of UV films, and finally a 5172-UV film.
Preferably, the UV film is gently smoothed with a brush after being adhered. Because the resin sheet is thin and the texture is fragile, the sheet is easy to crack due to uneven force application, the film crack is easy to occur after the film is coated, and the brush is used for gently smoothing, so that the adsorption is facilitated, and the film crack is prevented.
Preferably, 80mW/cm is adopted for the dispergation of the UV film2Irradiating with ultraviolet ray of intensity to release the gel in the channel for 30 s.
Preferably, the AR plating film has a thickness of 200-300 nm. In designing an AR film system, it is necessary to reduce the deformation of the resin sheet by designing the film thickness as low as possible.
Preferably, before AR coating, a temperature sticker with the measurement temperature of 77-99 ℃ is attached to the surface of the cut waste resin sheet to carry out complete AR coating, the visible temperature is 77 ℃, three continuous repeated tests are carried out, the temperature is 77 ℃, and the temperature during AR coating is judged to meet the requirement.
Preferably, when the sheet is taken, the operation of removing the glue needs to be repeated twice after the UV film is removed, namely, a corner is torn from the edge of the UV film to confirm whether the small-sized resin sheet pieces naturally fall off or not, and if not, the glue needs to be removed again.
The invention has the beneficial effects that: according to the process, the large-size resin sheet is cut into small-size resin sheet pieces, the UV film is attached to the small-size resin sheet pieces for AR film coating, the power and the time interval of each film coating are strictly controlled during film coating, the phenomenon that the temperature exceeds 85 ℃ to cause the change of the characteristics of the resin sheet is prevented, the deformation of a product is reduced, the surface film crack of the product is prevented, the processing quality of the product is improved, and the yield is improved.
