Description

Method for manufacturing curved cover member for manufacturing electronic device
Technical Field
The present invention relates to a method for manufacturing a curved cover member for manufacturing an electronic device, and a curved cover member manufactured by the manufacturing method.
Background
With the recent development of electronic devices, various electronic devices and apparatuses such as smart phones, tablet computers, TVs, and displays mounted on vehicles have been introduced. Such a display device has a cover member for protecting the inside against external impact at the outermost side, and the cover member is provided on the front surface of the panel to protect the touch screen panel, the display panel, or the surface of the electronic device.
Such a cover member has been generally flat, but recently, a cover member having a curved surface has been increasingly used in order to emphasize a design level or provide additional functions of an electronic device. However, since a process for reinforcing the cover member is required before the cover member is attached to the electronic device, it is difficult to shield or protect the opposite side surface of the cover member having a curved surface in order to reinforce any one of the side surfaces.
Conventionally, a film is attached to one side surface of a lid member to protect the surface in a process of reinforcing the lid member. However, in the case of the film, the three-dimensionally curved surface portion exhibits a film lifting phenomenon, and thus it is practically difficult to perfectly attach the film to the three-dimensionally curved surface of the cover member without lifting. The coating film forming liquid penetrates the surface where such a lifting phenomenon (adhesion failure portion) occurs, and a problem occurs in that the coating film forming liquid is formed to a portion where reinforcement or coating is not necessary. In particular, when the curvature radius of the curved surface is small, the problem of poor film adhesion is increased.
In order to solve the film lifting phenomenon, a film having improved adhesion and high adhesion strength may be used (for example, korean patent laid-open No. 10-2133641). However, in this case, since the adhesive remains on the surface of the lid member when the film is peeled off, there is a possibility that surface defects may occur in the later process.
In addition, when a film is used, the film may be exposed to a high-temperature environment of about 100 to 150 ℃ in a thermoforming process or a drying process after coating in a state where the film is attached to the lid member, and the film may be stored in a state of about 40 to 60 ℃ for a long period of time in a state where the film is attached. In this case, there is a possibility that the film adhesion force is significantly increased, and the film is difficult to peel off, and the surface defect is increased after peeling off, and the adhesive remains on the surface of the lid member. Further, the heat treatment in the thermoforming process or the drying process after coating may cause a peeling phenomenon in which the film is lifted.
Especially, with the recent advanced technology, ultra-thin glass (UTG) is widely used to protect the screen of electronic equipment. However, UTG is very thin and therefore has a high risk of breakage and is difficult to machine and treat its surface without damaging the glass. When the film is attached to protect the surface of UTG, there is a problem that glass is damaged due to impact during film attachment.

The release resin composition may be printed on all or a part of one side surface of the cover member. The combination of the release resin is printed on the surface of the cover member, and the printed portion can be protected and shielded from other processes. Therefore, the printing portion, region, or shielding portion, region may vary depending on the purpose, and the release resin composition may be printed not only on the entire surface of the cover member but also on only a part thereof.
The printing (i) of the release resin composition in the step (1) may be performed at a head speed of 1 inch/second to 25 inches/second. And the print head speed may be, but is not limited to, 1 to 20 inches/second, 5 to 20 inches/second, 10 to 20 inches/second, 12 to 20 inches/second, 14 to 18 inches/second, or 15 to 18 inches/second.
The printing of the release resin composition in the step (1) may be performed at (ii) a head height of 0.1mm to 10mm at the uppermost end of the cover member. And the head height at the time of printing may be 0.1mm to 8mm, 0.1mm to 5mm, 0.1mm to 3mm, 0.5mm to 2mm, or 1.0mm to 2mm, but is not limited thereto.
The printing (iii) of the release resin composition in the step (1) may be performed at least once. And the number of printing may be two or more, three or more, four or more, five or more, or six or more, but is not limited thereto. The printing of such a release resin composition can be adjusted according to the thickness of the protective film to be printed on the surface of the cover member.
The printing of the release-type resin composition in the step (1) may be performed as (iv) forming a protective film having a uniform thickness. The thickness of the protective film may be 1 μm to 100 μm, may be 1 μm to 80 μm, 1 μm to 60 μm, 1 μm to 40 μm, 1 μm to 20 μm, 2 μm to 18 μm, 4 μm to 16 μm, 6 μm to 14 μm, 8 μm to 12 μm, 9 μm to 11 μm, but is not limited thereto.
According to an embodiment, the step (1) may further include a step of UV-curing the surface printed with the release resin composition. According to an embodiment, the UV curing may be performed by a UV LED.
The time interval between the printing and the UV curing of the release resin composition in the step (1) may be about 100ms or more, about 200ms or more, about 300ms or more, about 400ms or more, about 500ms or more, about 600ms or more, about 700ms or more, about 800ms or more, about 900ms or more, and may be less than about 1 second. The time interval between printing and UV curing may vary depending on the printing speed.
The interval between the head and the curing means (e.g., UV lamp) in the step (1) may be about 20cm to about 50cm, about 25cm to about 45cm, or about 30cm to about 40cm, but is not limited thereto.
The cumulative amount of light upon UV curing in said step (1) may be 10 to 1,000mJ/cm 2 20 to 900mJ/cm 2 、20 to 800mJ/cm 2 30 to 700mJ/cm 2 40 to 600mJ/cm 2 50 to 500mJ/cm 2 60 to 400mJ/cm 2 70 to 300mJ/cm 2 100 to 200mJ/cm 2 120 to 200mJ/cm 2 140 to 200mJ/cm 2 160 to 190mJ/cm 2 Or 170 to 190mJ/cm 2 . If the cumulative light amount is less than the minimum value, the protective film may be insufficiently cured, and if the cumulative light amount exceeds the maximum value, the protective film may not be peeled off due to excessive curing. Wherein the accumulated light amount may be based on UVA 2.
According to the manufacturing method of one embodiment, the step (1) may be further followed by (2) a step of forming a coating film on an opposite side surface of the curved surface cover member { the following step (2) }; and (3) a step of peeling the protective film from the curved surface cover member { the following step (3) }.
The step (2) may include a step of applying the coating liquid on the reverse side of the curved cover member, and a step of drying the curved cover member applied with the coating liquid.
The coating liquid is not limited as long as it is a coating composition for imparting a function to one side surface of the curved surface cover member. For example, the coating liquid may be a chemical strengthening liquid, a non-reflective coating liquid (AR coating), an anti-fingerprint coating liquid (AF coating), a transparent electrode coating liquid, or a black ink coating liquid.
The side surface of the printing release resin composition may vary depending on the type of the coating liquid or coating film. The release resin composition can be formed on the opposite side of the curved cover member to which the coating liquid is printed or on which the coating film is formed. For example, in the case where the coating liquid is of a type such as a non-reflective coating liquid printed on the outer side of the curved surface cover member, the release resin composition may be printed on the inner side of the curved surface cover member before the coating liquid is printed, and in the case where the coating liquid is printed on the inner side of the curved surface cover member like an anti-fingerprint coating liquid, the release resin composition may be printed on the outer side of the curved surface cover member before the coating liquid is printed.

The present invention relates to a curved cover member manufactured by a manufacturing method according to an embodiment. The curved cover member thus manufactured can be used to manufacture various electronic devices.
Cover part
According to an embodiment of the present invention, the cover member may be made of a material belonging to various types, and is not particularly limited, and may be arbitrarily selected from known ones that can be generally used in various electronic equipment products such as a display.
The cover member may be made of glass or a polymer material, but is not limited thereto as long as it is a transparent material capable of manufacturing the cover member.
The glass may be a soda-lime-silica type glass, a borate glass, an aluminum glass, one or more additives (for example, an inorganic colorant, an oxidizing compound, a viscosity modifier, and/or a melting accelerator) uniformly distributed in the glass. The glass may also be strengthened glass or ultra-thin glass (UTG).
The glass may be clear or tinted.
Examples of the polymer material include polyethylene terephthalate, polycarbonate, polymethyl methacrylate, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polystyrene, polyimide, polyamide, polybutylene terephthalate, polyethylene naphthalate, polysulfone, polyether sulfone, polyether ether ketone, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, triacetyl cellulose, polyurethane, and cyclic olefin polymer. One or more of these polymers may be contained, or two or more of these polymers may be used in a laminated state.
The cover member may be a curved cover member having a curved surface. Here, the curved surface may be formed inside or outside the cover member, and the curvature radius of the curved surface is not limited, and for example, the curvature radius may be 1R to 20R. The curved surface formed at the cover member may represent a three-dimensional curved surface, and the three-dimensional curved surface may have a concave or convex shape. Such a curved surface may be formed on the inner side surface of the cover member in the case where the three-dimensional curved surface is a concave shape, and may be formed on the outer side surface of the cover member in the case where the three-dimensional curved surface is a convex shape.
In the present specification, a curved surface means a broad concept including not only a zigzag shape but also a shape covering corners of a tape. For example, the "curved surface" described in the present specification may be included in a case where the inside of the lid member is concavely formed such that three surfaces are arranged at an angle of 120 ° with respect to adjacent surfaces or are formed convexly at an angle of 240 ° on the outside.

The cover member may have any thickness and may vary depending on the application of the cover member. For example, the lid member may be 10 μm or more, 20 μm or more, 30 μm or more, 40 μm or more, 50 μm or more, 60 μm or more, 70 μm or more, 80 μm or more, 90 μm or more, 100 μm or more, 200 μm or more, 300 μm or more, 400 μm or more, 500 μm or more, 600 μm or more, 700 μm or more, 800 μm or more, 900 μm or more, or 1000 μm or more, and may be 5mm or less, 4mm or less, 3mm or less, 2mm or less, or 1mm or less.
Peeling off
The peeling method may be performed by a known peeling method, and for example, a dipping method (immersion method), a shower method, a spray method, a brush method, a transfer method, or the like may be used.
The stripping can be performed using a stripping solution. The curved surface cover member may be immersed in the stripping solution for 10 seconds to 10 minutes, 30 seconds to 10 minutes, 1 minute to 5 minutes, 1 minute to 3 minutes, or 1 minute to 2 minutes to perform stripping, where the stripping may be performed in a stripping tank containing such a stripping solution.
The peeling device may vary depending on the application and size of the curved cover member or the electronic device to which the curved cover member is attached. An ultrasonic process is added to smoothly peel the protective film during the peeling process.
