Description

Technical Field

[0001] The invention belongs to the field of processing glass coatings, and in particular relates to a processing technology for a 2.5D glass anti-glare coating. Background Art

[0002] The 2.5D glass screen structure has a specific design logic. There is a flat area in the center of the glass. Then, based on this flat surface, the edge part is polished to a curved shape. The unique shape created by this process is commonly known as the "water drop screen" in the mobile phone industry. In order to expand the functional dimension of the screen and improve the user experience, screen surface treatment has become a key link. Taking the glass anti-glare process as an example, a layer of anti-glare coating needs to be accurately applied to the glass surface. After uniform spraying and curing, the coating gives the glass surface a unique frosted texture. Compared with conventional glass, the significant advantage of anti-glare glass is that its specular reflection is significantly reduced. Especially when placed in extremely strong light scenarios, it can effectively reduce the specular reflection luminous flux entering the human eye, thereby achieving an ideal anti-glare effect and effectively ensuring the comfort of visual perception.

[0003] However, in the actual business promotion, some customers have put forward special customization requirements, explicitly requiring that the curved part of the edge of the screen present a highly smooth visual and tactile effect, which means that this specific area cannot be covered with anti-glare coating. In order to meet this special demand, our company has improved the existing spraying process. Summary of the invention

[0004] The purpose of the present invention is to provide a processing technology for a 2.5D glass anti-glare coating with a smooth edge and a frosted inner side.

[0005] To achieve the above object, the present invention provides a processing technology for a 2.5D glass anti-glare coating, comprising the following steps:

[0006] a. Clean several screens to be processed and place them evenly on the bottom tray to ensure that the screens do not shake; b. Put a first shielding member on the top of the bottom tray, and the first shielding member is provided with several spraying notches, so that the first shielding member covers the edges of the four sides of each screen, and the spraying notches expose the front area of ​​each screen; adjust the temperature of the first spraying room, spray the anti-glare coating on the several screens, and then transfer the entire bottom tray, the first shielding member and the several screens to a constant temperature room to wait for the anti-glare coating to solidify;

[0007] c. Using the first shielding member and the spraying notch thereof as a positioning frame, insert a second shielding member into each of the spraying notches, wherein the size of the second shielding member is equal to the size of the spraying notch, so that a plurality of the second shielding members cover the front area of ​​the corresponding screen, and remove the first shielding member to expose the edges of the plurality of screens again; adjusting the temperature of the second spraying chamber, spraying the anti-fingerprint coating on a plurality of screens, and then transferring the entire tray, the second shielding member and the plurality of screens to a constant temperature chamber to wait for the anti-fingerprint coating to solidify;

[0008] d. Remove some of the second shielding members, transfer the bottom tray and some screens to the polishing station, and use a polishing head to polish the anti-glare coating and the transition between the anti-glare coating and the anti-fingerprint coating to make the interface between the two coatings transition smoothly.

[0009] e. Remove several screens, clean the screens, bottom tray, first shielding member and several second shielding members.

[0010] As an improvement of the above solution, a plurality of positioning posts and positioning holes are provided between the bottom tray and the first shielding member.

[0011] As an improvement of the above solution, the bottom tray is provided with a plurality of grooves for placing the screen, the screen is clamped and fixed by the inner walls of the grooves on all sides, and the sides of the grooves are provided with ear-shaped grooves for the user to pick up the screen from the edge of the screen and remove it.

[0012] As an improvement of the above-mentioned scheme, the bottom tray, the first shielding piece and several of the second shielding pieces are all made of bakelite, several of the grooves and several of the spray-painted notches are carved by a milling machine, and the first shielding piece is provided with an arc surface at the bottom of the spray-painted notch so that the arc surface fits the screen.

[0013] As an improvement of the above solution, the second shielding member is provided with an anti-slip layer on a side close to the screen.

[0014] As an improvement of the above solution, the temperature of the first spraying chamber is 180-230°C, and the temperature of the second spraying chamber is 20-30°C.

[0015] The present invention has the following beneficial effects: the thickness of the anti-glare coating itself is relatively large. If it is produced separately, there will be a slight height difference between its edge and the screen surface, and this height difference has a significant effect on the feel. In view of this, this solution adopts the method of spraying an additional anti-fingerprint coating on the edge of the screen and polishing the excess anti-glare coating. In this way, firstly, the problem of easy powder loss on the surface of the anti-glare coating can be solved; secondly, the silky touch and good transparency of the edge of the screen can be maintained without destroying the customer's unique design plan for the screen; thirdly, the height difference between the anti-glare coating and the anti-fingerprint coating can be cleverly reduced, allowing users to have a smoother and smoother touch experience when touching the screen.

[0016] In the process of spraying these two coatings in sequence, the use of a bottom tray, a first shielding member and a plurality of second shielding members can greatly speed up the shielding operation, improve the shielding accuracy, effectively reduce the labor intensity of the operator, and thus comprehensively improve the overall production efficiency.

[0025] c. Using the first shielding member 20 and the spraying gaps thereof as positioning frames, insert the second shielding member 30 into each of the spraying gaps, wherein the size of the second shielding member 30 is equal to the size of the spraying gap, so that a plurality of the second shielding members 30 cover the front area of ​​the corresponding screens, and removing the first shielding member 20 re-exposes the edges of a plurality of screens; adjusting the temperature of the second spraying room, spraying the anti-fingerprint coating on a plurality of screens, and then transferring the entire tray, the second shielding member 30 and a plurality of screens to a constant temperature room to wait for the anti-fingerprint coating to solidify.

[0026] d. Remove some of the second shielding members 30, transfer the bottom tray 10 and some screens to the polishing station, and use a polishing head to polish the anti-glare coating and the transition between the anti-glare coating and the anti-fingerprint coating to make the interface between the two coatings transition smoothly.

[0027] e. Remove several screens, clean the screens, the bottom tray 10, the first shielding member 20 and several second shielding members 30;

[0028] The above parts can be used repeatedly.

[0029] As an improvement of the above solution, a plurality of positioning posts 21 and positioning holes 22 are provided between the bottom tray 10 and the first shielding member 20. Figure 1 As shown, the bottom tray 10 is a whole, and positioning posts 21 are provided at the four corners of the whole; the first shielding member 20 is a whole, and positioning holes 22 are provided at the four corners of the whole.

[0030] As an improvement of the above solution, the bottom tray 10 is provided with a plurality of sinks 11 for placing the screen, and the screen is clamped and fixed by the inner walls of the sinks 11. The sides of the sinks 11 are provided with ear-shaped grooves 12 for users to pick up the screen from the edge. More grooves can be added to the bottom tray 10 as needed.
