[0036] like Figure 1 As shown, a method for manufacturing a glass panel of a computer keyboard comprises the following steps:

[0037] Step 1: Cutting: First, inspect the raw materials of the glass, use qualified glass panels for cutting, and perform preliminary processing on the raw materials of the glass and cut them into the required specifications and sizes;

[0041] Step 5: Printing layers: printing a pattern layer, a photosensitive layer and a shielding layer on the surface of the glass panel in sequence. The shielding layer shields the area except the pattern layer.

[0046] In the above specific embodiment, the items for inspecting the raw materials of the glass panel in step one include five aspects, namely material, appearance, size, structure and characteristics, wherein the material inspection is mainly to check the specifications and material; the appearance inspection is for aspects such as mold, scratches, cracks, air lines and pitting; the size inspection is to detect whether the raw materials of the glass panel meet the basic length, thickness and inner diameter; the structure and characteristics are judged by structural tests on the quality of the glass panel materials, and the glass panels that have passed the inspection are selected for cutting processing, and the raw materials of the glass panels are processed into the required specifications and sizes to facilitate subsequent processing.

[0047] As a further embodiment of the present invention, the special cleaning and drying equipment in step four includes a workbench, an ultrasonic cleaning box, a transfer assembly and a drying box. A drain pipe is provided at the bottom of the workbench, and the ultrasonic cleaning box is connected to one end of the drain pipe.

[0048] As a further embodiment of the present invention, the printed layer in step five needs to fix the ink, and the ink fixing method uses screen printing to print the ink onto the glass panel. The screen printing area is large. After printing, the glass needs to be baked to solidify the ink. The baking temperature of the glass panel is between 680°C and 720°C, and the baking time of the glass panel is 5-7 minutes.

[0049] It should be added that when the glass panel is printed with layers, the pattern layer is presented through photosensitivity when it is lit, and the shielding layer shields the area except the pattern layer. Since each layer uses different inks, each layer needs to be baked and reinforced after printing to prevent the ink from falling off, so as to form the required appearance effect of the finished product.

[0050] As a further embodiment of the present invention, the glass panel includes a front side and a back side, the pattern layer is printed on the front side of the glass panel, the pattern layer is screen-printed with pattern ink and fixed to the front side of the glass panel by high-temperature baking, the AG layer, the photosensitive layer and the shielding layer are all arranged on the back side of the glass panel, the top of the AG layer is tightly connected to the back side of the glass panel, the photosensitive layer is located between the AG layer and the shielding layer, the photosensitive layer is screen-printed with ink and baked to the bottom of the AG layer, and the shielding layer is fixed to the bottom of the photosensitive layer by a shielding ink screen through baking.

[0051] As a further embodiment of the present invention, a strengthening layer is arranged between the AR layer and the pattern layer, the AR layer and the strengthening layer are arranged above the pattern layer, and the AR layer is fixed above the strengthening layer.

[0052] As a further embodiment of the present invention, the tempering treatment in step 6 includes physical tempering and chemical tempering. The glass panel needs to be physically tempered first and then chemically tempered. The steps of the glass panel tempering treatment are:

[0053] Step 1: First, the glass panel is physically tempered. The physical tempering is to heat the glass panel to 650°C-700°C by using a gas medium tempering method to make the tempered glass easy to shape. Then, air is blown to both sides of the glass panel to cool it quickly, and then the quality of the glass panel is inspected. Then, the glass panel is chemically tempered.

[0054] Step 2, chemically tempering the glass panel based on physical tempering, wherein the chemical tempering is to immerse the glass panel in a salt solution at a temperature of 420° C. at 750° C., so that the sodium ions and potassium ions in the glass panel are exchanged with the lithium ions in the salt solution, resulting in a crowding phenomenon, thereby completing the chemical tempering treatment of the glass panel;

[0055] Step 3: After the glass panel has been physically and chemically tempered, the outer surface of the glass panel is cleaned to remove the molten salt residue on the surface, and finally the glass panel is dried to ensure a clean surface.

[0056] The purpose of chemically tempering the glass panel is to change the composition of the surface layer of the glass panel based on the natural diffusion and mutual diffusion of ions, thereby forming a surface compressive stress layer. At the same time, by controlling the temperature and immersion time, the strength and performance of the glass panel can be optimized, thereby improving the strength of the glass keyboard and increasing the strength of the glass panel.

[0057] In addition, the purpose of physically tempering the glass panel is to eliminate the internal stress of the glass panel and avoid local damage that causes the glass to break into countless small pieces. Chemically tempering the glass panel is to increase the strength of the glass panel by changing the chemical composition of the glass panel surface. Cleaning the chemically tempered glass panel is to remove the residual chemical reagents and floating sediments on the surface of the glass panel.

[0058] The glass panels were made by the above method, and four identical glass panels were taken for testing. The specific method is as follows: Specific embodiment 1

[0060] The glass panel is processed through the above steps 1 to 9, and then the strength, light transmittance and reflection intensity of the glass panel are tested.

[0061] Comparative Example 1.1

[0062] This comparative example is substantially the same as the specific embodiment 1, except that the glass panel is not subjected to tempering treatment, and then the strength, light transmittance and reflection intensity of the glass panel are tested.

[0063] Comparative Example 1.2

[0064] This comparative example is substantially the same as the specific embodiment 1, except that the glass panel is not subjected to AR coating treatment, and then the strength, light transmittance and reflection intensity of the glass panel are tested.

[0065] Comparative Example 1.3

[0066] This comparative example is basically the same as the specific embodiment 1, except that the glass panel is not subjected to tempering and AR coating treatment, and then the strength, light transmittance and reflection intensity of the glass panel are tested.

[0067] The above four glass panels were tested and the test results were as follows:

[0068] Table 1 Effects of different manufacturing methods on glass panel strength, transmittance and reflection intensity

[0069]

[0070] It can be seen from Table 1 that in the process of manufacturing the keyboard glass panel, tempering and AR coating the glass panel are beneficial to improving the strength and light transmittance of the glass panel, while reducing the reflection intensity of the glass panel, thereby reducing the glare of the glass panel and improving the display effect of the glass panel.

[0071] As a further embodiment of the present invention, the processing steps of the AR coating treatment in step eight are as follows:

[0072] 1) Use alkaline solution and ultrasonic cleaning method to clean the glass panel after the white film inspection, and completely clean the oily substances and dirt on the surface of the glass panel;

[0073] 2) Cover the cleaned glass panel with a protective film to prevent it from absorbing moisture and stains from the air;

[0074] 3) Fix the coated glass panel on the table of the magnetron sputtering coating machine and tear off the coating on the surface of the glass panel;

[0075] 4) Using ICP ions and argon gas to clean the volatile substances on the surface of the glass panel;

[0076] 5) coating the glass panel with a silicon nitride layer by vacuum magnetron sputtering using a silicon target and nitrogen, wherein the silicon nitride layer has two layers;

[0077] 6) The glass panel coated with the silicon nitride layer is taken out from the table of the magnetron sputtering coating machine, and the silicon nitride layer on the surface of the glass panel is cleaned by alkaline solution and ultrasonic cleaning method;

[0078] 7) then repeating the film coating step and the step of plating a silicon oxide layer, so that the outermost layer is a newly plated silicon oxide layer;

[0079] 8) Coating an AF film layer: electrify the AF pill, and coat the surface of the outermost silicon oxide layer with an AF film layer by vacuum magnetron sputtering coating method, thereby obtaining an AR coated glass panel.

[0080] It should be added that in the process of coating the glass panel with silicon nitride layer by vacuum magnetron sputtering coating, it is necessary to apply 3KW of electric energy to the silicon rake, turn on the nitrogen discharge, and the flow rate is about 220sccm. After the silicon rake is powered on, high temperature will be generated, and atoms will be bombarded out through a physical process, that is, the silicon rake will be sublimated into silicon molecules. Through the magnetron directional acceleration method, the silicon molecules are accelerated into high-energy ions. The silicon molecules pass through the nitrogen layer, and the nitrogen is also heated up. The silicon molecules and nitrogen molecules react chemically at high temperature to form silicon nitride. The silicon nitride after the reaction is still an extremely high-speed ion. The atoms pass through the vacuum and are physically bombarded and finally deposited on the surface of the product to be plated to form a second layer of silicon nitride. After the set power-on and ventilation are completed, the silicon rake is powered on and the nitrogen is stopped. The vacuum pump continues to operate to extract the unreacted nitrogen and the silicon nitride vapor that is not deposited on the surface of the product out of the magnetron sputtering coating machine. The designed thickness of the silicon nitride layer is 5-8rm.

[0081] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that these specific embodiments are only illustrative, and those skilled in the art may omit, replace, and change the details of the above methods and systems in various ways without departing from the principles and essence of the present invention. For example, merging the above method steps so as to perform substantially the same functions in substantially the same manner to achieve substantially the same results is within the scope of the present invention. Therefore, the scope of the present invention is limited only by the appended claims.
