The beneficial effect is that the bottom of the glass cup except the pattern part is beaten into a frosted surface, and a raised pattern surface is formed, which has a three-dimensional effect, and the pattern surface and the frosted surface can be coated with multiple layers of silver paste without affecting the pattern quality, and the bonding force between the silver paste and the frosted surface is better. After polishing, the pattern has high brightness, forming a sharp contrast with the frosted surface, and the pattern is clearer and more thorough.

Description

Technical Field

[0001] The invention relates to the field of cup pattern design, and in particular to a method for making a silver layer pattern on the bottom of a glass cup. Background Art

[0002] In the past, the silver layer pattern was made on the bottom of the glass cup by applying silver paste to the bottom of the inner cup, then baking it at about 180℃, and then using a laser marking machine to punch through the silver layer to form a silver layer pattern (the effect is shown in the figure). Figure 1 As shown in the figure). The pattern formed in this way has a poor three-dimensional sense and is not clear. In addition, the bonding degree between the silver paste and the glass surface is poor, and multiple layers of silver paste cannot be applied. If multiple layers of silver paste are applied, it is not easy to penetrate the silver layer during laser marking. Summary of the invention

[0018] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0019] The present invention provides a method for manufacturing a silver layer pattern on the bottom of a glass, comprising the following steps:

[0020] Step 1: According to the pattern, use a laser marking machine to mark the bottom of the glass cup with a laser, forming a raised and smooth three-dimensional pattern surface and a frosted surface around the pattern; the raised three-dimensional pattern surface is 0.2mm-1mm higher than the frosted surface. When laser marking, the rest of the pattern is marked to form a frosted surface. The frosted surface can improve the bonding strength between the silver paste and the glass, and can form a three-dimensional glass pattern. The glass pattern surface is smooth, and it has a more three-dimensional effect after applying the silver layer.

[0021] Step 2: Apply multiple layers of silver paste evenly on the raised pattern surface and the frosted surface of the bottom of the cup; preferably, apply 3 layers of silver paste on the raised pattern surface and the frosted surface of the bottom of the cup, and the thickness of the silver paste layer is 0.2mm-0.5mm. When making silver layer patterns in the prior art, the silver layer cannot be applied too thickly. If it is too thick, the laser marking machine cannot penetrate it, and the pattern quality is poor and unclear. If it is applied too thinly, coupled with poor bonding strength, the silver layer is easy to fall off or damage, and the silver layer pattern will become blurred after long-term use. By adopting the technical process of this application, multiple layers of silver paste can be applied, which is not easy to fall off, and the pattern is clear and can be used for a long time.

[0022] Step 3: Bake the glass cup coated with the silver layer at 550℃-580℃ for 30 minutes. The glass cup will be off-white before baking and silver-white after baking. The silver layer can be solidified on the bottom glass of the cup to improve the bonding strength.

[0023] Step 4: Polish the silver layer on the bottom of the glass. The brightness of the silver layer on the raised pattern is higher than that on the frosted surface. Since the pattern is raised and the pattern surface is smooth, after polishing, the brightness of the silver layer on the pattern will be much higher than that on the frosted surface, and the three-dimensional effect of the pattern will be better.

[0024] During polishing, a cleaning ball is placed in the cup body, and then a rotary drive mechanism is used to drive the cleaning ball to rotate and polish on the silver layer until the silver layer on the raised pattern is bright.

[0025] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
