[0033] Based on the existing technology, the glass production line capacity of traditional methods such as float glass and calendering method is too large, and it is not convenient to switch materials, which cannot meet the production needs of niche electronic eyes for a wide variety of colored glass. This application proposes a glass production device that adapts to the production characteristics of niche colored glass, which produces various types of colored glass in a simple, low-cost and small-batch manner, solving the problem that the existing glass production cannot produce a variety of colored glass quickly and at low cost. Figures 1 to 4 That is, a schematic embodiment of the glass production device of the present application is shown.

[0034] like Figures 1 to 4As shown, the present application discloses a glass production device, which includes: a molding assembly, the molding assembly includes a molding table 1, and the molding table 1 is provided with a molding groove 11. A casting assembly, the casting assembly includes a crucible 2, and the crucible 2 can be tilted above the molding groove 11. A calendering assembly, the calendering assembly includes a calendering roller 3, the calendering roller 3 is rollingly arranged on the molding table 1, and the rolling path of the calendering roller 3 covers the molding groove 11.

[0035] Through the above-mentioned structural design, the embodiment of the present application can melt the glass liquid 4 of different components in a small color through the crucible 2, and pour the glass liquid 4 into the molding tank 11, flatten the glass liquid 4 through the calendering roller 3, and anneal it to form a glass substrate 5, so as to meet the optical requirements of various "electronic eyes" for different colors of glass. Since the embodiment of the present application has a simple structure, a small batch size, and is easy to change the glass formula, the glass production cost is reduced and the production process is simplified.

[0036] In some embodiments of the present application, Figure 2 As shown, the forming table 1 is also provided with a ring-shaped residual liquid groove 12, and the residual liquid groove 12 is arranged around the forming groove 11. When glass is produced, the glass liquid 4 is poured from the crucible 2 into the forming groove 11 and overflows the forming groove 11. The calendering roller 3 rolls along the forming table 1 to flatten the glass liquid 4. At this time, the excess glass liquid 4 will be squeezed out and pushed into the residual liquid groove 12 around, thereby avoiding the excess glass liquid 4 from affecting the movement of the calendering roller 3 and improving the surface flatness of the prepared glass substrate 5. At the same time, the present application adopts the method of overflowing the glass liquid 4 in the forming groove 11 and flattening it by the calendering roller 3, which can also ensure that the calendering roller 3 is in full contact with the glass liquid 4, so that the surface of the prepared glass substrate 5 is full and free of defects such as bubbles and sand holes.

[0037] In some embodiments of the present application, the casting assembly further includes a first driving mechanism for driving the crucible 2 to move, and the calendering assembly further includes a second driving mechanism for driving the calendering roller 3 to roll. The first driving mechanism connects and supports the crucible 2 to achieve the overturning control and movement control of the crucible 2. The second driving mechanism is synchronously linked with the first driving mechanism, so that the calendering roller 3 can follow the crucible 2 to roll synchronously and uniformly, so that after the crucible 2 pours the molten glass liquid 4 into the molding tank 11, the flattening process is performed promptly and quickly to avoid the glass liquid 4 cooling in the environment and causing changes that affect the molding quality.

[0038] In some embodiments of the present application, the forming assembly further includes a third driving mechanism, which can drive the forming table 1 to move back and forth to enter and exit the annealing furnace, so that the present application can send the forming table 1 together with the glass liquid 4 thereon into the annealing furnace for annealing after the calendering roller 3 flattens the glass liquid 4. After the glass substrate 5 is completely annealed, conventional processing steps such as polishing and cutting are performed to produce small glass sheets required for various "electronic eye" devices.

[0039] In some embodiments of the present application, Figure 3 As shown, a cooling water channel is provided in the calendering roller 3, and the cooling water channel is provided with a water inlet 31 and a water outlet 32 ​​connected to the circulating water system. The cooling cycle of the calendering roller 3 is realized through the water inlet 31 and the water outlet 32, so as to control the temperature of the surface of the calendering roller 3 to be constant, so as to ensure that the cooling effect of the calendering roller 3 on the glass liquid 4 is stable and consistent when the calendering roller 3 calenders the glass liquid 4, and improve the quality stability of the formed glass substrate 5.

[0040] In addition, if Figure 3 As shown, the two sides of the calendering roller 3 are rotating shafts 33, and the rotating shafts 33 are provided with grooves for use with guide rails, so as to ensure the smooth movement of the calendering roller 3 and improve the flattening effect of the calendering roller 3 on the molten glass 4. It can be understood that the calendering roller 3 can be separated from the surface of the forming table 1 so as not to interfere with the operation of sending the forming table 1 and the molten glass 4 into the annealing furnace for annealing. For example, guide rails that cooperate with the calendering roller 3 are set on both sides of the forming table 1. When the calendering roller 3 reaches the end of the forming table 1, it can be supported by the guide rails instead, so as to be separated from the forming table 1, so as to facilitate the third driving mechanism to send the forming table 1 and the molten glass 4 into the annealing furnace for annealing. Among them, the third driving mechanism can be a conveyor belt or a moving vehicle body.

[0041] In some embodiments of the present application, the bottom of the forming groove 11 and the surface of the calendering roller 3 are provided with an electroplated chrome layer, which has the beneficial effects of high temperature resistance, corrosion resistance, wear resistance and improved flatness. The thickness of the electroplated chrome layer is 20-200 μm, which meets the requirements of durability and flat surface of the glass liquid 4 on the basis of controlling the production cost and process difficulty. Among them, the surface roughness Ra of the electroplated chrome layer is ≤0.2nm, so the glass substrate 5 produced by it also has a surface roughness quality of ≤0.2nm.

[0042] In some embodiments of the present application, the forming table 1 and the calendering roller 3 are both made of refractory steel, and the forming table 1 can be directly formed by pouring molten steel. The crucible 2 is made of one or more of precious metals, quartz and corundum, and the specific material and annealing process are determined according to the desired molten color glass components.

[0043] In some embodiments of the present application, the thickness of the forming table is ≥20mm, the dimensions of the forming groove are: 2000mm≥length L>500mm, 300mm≥width W>50mm, depth H≥0.4mm, so that large pieces of glass with a thickness of ≥0.4mm, 2000mm≥glass length>500mm, 300mm≥glass width>50mm, and a surface roughness of Ra≤0.2nm can be produced.

[0044] In some more preferred embodiments of the present application, the thickness of the forming table is ≥30mm, the dimensions of the forming groove are: 1500mm≥length L>800mm, 200mm≥width W>100mm, depth H≥1mm, and the surface roughness Ra of the electroplated chrome layer is ≤0.1nm. Thus, large pieces of glass with a thickness of ≥1mm, 1500mm≥glass length>800mm, 200mm≥glass width>100mm, and a surface roughness of ≤0.1nm can be produced.

[0045] In some embodiments of the present application, the forming table and the crucible are respectively provided with multiple different groups, so as to be respectively used for producing glass substrates of different sizes or different compositions.
