Description

Technical Field

[0001] The invention relates to the technical field of glass processing equipment, in particular to a laminating process for an outer surface coated glass component. Background Art

[0002] Coated glass components are widely used in modern architecture, automotive, electronics, and energy industries, playing a particularly important role in improving building energy efficiency, enhancing indoor comfort, and enhancing product aesthetics. Coated glass typically refers to glass surface coated with a thin layer of functional coating, which can be made of metal oxides, polymers, or other specialty materials. Coated glass provides a variety of additional functions by modifying the optical, electrical, and thermal properties of glass, such as UV protection, anti-reflection, thermal insulation, anti-fouling, and anti-fingerprint. With the promotion of energy conservation and environmental protection concepts, the demand for glass in the construction field has also changed significantly. Traditional single-piece glass can no longer meet the requirements of modern buildings for thermal insulation, UV protection, and privacy protection. Coated glass has emerged as a result. By adding a coating to the glass surface, it can not only significantly improve the performance of the glass, but also reduce the energy consumption of the building. For example, low-emissivity (Low-E) glass coatings can effectively block infrared and ultraviolet radiation while maintaining a stable indoor temperature, reducing the burden of air conditioning and heating, thereby saving energy and improving living comfort. With the continuous advancement of technology, the application of coated glass has continued to expand, from traditional UV protection and thermal insulation functions to gradually developing higher-performance products such as smart dimming glass and antibacterial glass. For example, smart dimming glass adjusts light transmittance through an electrically controlled thin film, which can automatically adjust indoor light without the need for mechanical shading devices, greatly improving the energy efficiency and comfort of buildings and cars. However, the production process of coated glass also faces many challenges. The uniformity, adhesion, durability and cost control of the coating are key factors affecting its wide application. Therefore, how to improve coating materials, optimize production processes, further improve the performance of coated glass, and reduce production costs remains a hot topic in current research and industrial production.

[0003] The patent (application number: CN201810412980.4) discloses a curved glass component laminating device and its laminating process, including a chassis, a blower fan is provided on the top of the chassis, and a plurality of electric heating tubes are evenly arranged on the top wall inside the chassis. The characteristics are: a heating chamber is provided inside the chassis, a main vent is provided on the top of the heating chamber, and a plurality of auxiliary vents are provided on the side walls of the heating chamber. A plurality of laminating cavities are provided in the heating chamber, and the laminating cavity includes an upper frame, an upper cover, a lower frame, and a tray. The upper cover is installed on the upper frame, and the tray is installed on the lower frame. The upper cover and the tray are both made of flexible high-temperature resistant materials. The present invention has advantages such as good lamination effect.

[0004] This patent and existing technologies present the following technical issues in practical use: Currently, various glass encapsulation processes on the market mostly utilize lamination with silicone sheets. Atmospheric pressure is applied to the silicone sheets, which then exerts pressure on the components, thereby bonding the glass films together. This is a mature glass encapsulation process on the market, but it is not suitable for encapsulating coated glass. Coated glass has a coating on its outer surface, which comes in a variety of materials. Direct pressure of the silicone sheet against the coating would damage it and render it inoperable. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems and provide a lamination process for an outer surface coated glass assembly.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A lamination process for an outer surface coated glass assembly comprises the following steps:

[0008] S1. First, the upper pressing plate and the pressing strip are raised to a certain height so that the glass assembly can be transported to the heating plate, and a pressing frame is placed on the upper edge of the glass assembly;

[0009] S2. Next, the upper pressing plate, the layering strip, and the silicone plate move downward as a whole. At this time, the layering strip is pressed tightly against the heating plate. The height of the upper pressing plate is controlled to prevent the upper pressing plate from contacting the pressing frame. At this time, the upper pressing plate, the layering strip, the silicone plate, and the heating plate form a lamination chamber, which can be vacuumed.

[0010] S3. After vacuuming is completed, the heating plate heats up and the film reaches a softened state. At this time, the upper pressing plate moves downward until it presses the pressing frame and continues to apply pressure to achieve edge sealing of the glass.

[0011] S4. After the edges are sealed, the lamination cavity is inflated. The gas fills the lamination cavity and compacts the middle part of the glass. Then the next process can be entered.

[0012] Furthermore, a heating plate is fixedly installed on the inner top of the workbench, and a glass component is arranged above the heating plate.

[0013] Furthermore, a heating plate is fixedly installed on the inner top of the workbench, and a glass component is arranged above the heating plate.

[0014] Furthermore, a pressure strip is provided inside the workbench, a limit plate is fixedly installed on the inner wall of the pressure strip, an upper pressure plate is slidably installed on the inner wall of the pressure strip, and the upper pressure plate is located above the limit plate.

[0015] Furthermore, a silicone plate is fixedly mounted on the inner wall of the pressure strip, the silicone plate is located above the upper pressure plate, and a pressure frame is provided between the glass assembly and the upper pressure plate.

[0016] Furthermore, a vent hole is provided inside the pressing frame, and one side of the pressure strip is fixedly connected to a connecting pipe, which is configured as a rubber hose.

[0017] Furthermore, an air filling box is fixedly installed at the bottom of the workbench, a dual-purpose pump is provided inside the air filling box, and one end of the connecting pipe is fixedly connected to the output end of the dual-purpose pump.

[0021] Furthermore, an electric telescopic rod is fixedly installed on the top of the workbench, and the output end of the electric telescopic rod is fixedly connected to the upper pressing plate.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention heats the coated glass assembly, evacuates it, and then seals the edges to ensure that there are no bubbles between the coated glass and the film. Air is then filled in and the glass is pressed by air pressure. The air does not damage the coating and can also adhere the coated glass and the film together to achieve the packaging of the coated glass assembly. The PVB film between the coated glass and ordinary glass effectively improves the impact resistance of the glass.

[0024] 2.

The vacuum extraction and pressurization process ensures a more uniform adhesion of the glass components, preventing the ingress of air and impurities, and ensuring the quality of the laminated glass. This process improves the stability and consistency of the production process, reduces the production of substandard products, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] A lamination process of an outer surface coated glass assembly according to a preferred embodiment of the present invention will be described in detail below.

[0035] Example 1, as Figure 1-Figure 7 As shown, the following steps are included:

[0036] S1. First, the upper pressing plate 6 and the pressure strip 4 are raised to a certain height so that the glass assembly 3 can be transported to the heating plate 2, and the pressing frame 8 is placed on the upper edge of the glass assembly 3;

[0037] S2. Next, the upper pressing plate 6, the layering strip 4, and the silicone plate 7 move downward as a whole. At this time, the layering strip 4 is pressed tightly against the heating plate 2. The height of the upper pressing plate 6 is controlled to prevent the upper pressing plate 6 from contacting the pressing frame 8. At this time, the upper pressing plate 6, the layering strip 4, the silicone plate 7, and the heating plate 2 form a laminated chamber, which can be vacuumed.

[0038] S3. Next, after vacuuming is completed, the heating plate 2 is heated and the film reaches a softened state. At this time, the upper pressing plate 6 moves downward until it presses the pressing frame 8 and continuously applies pressure to achieve edge sealing of the glass edge.

[0039] S4. After the edges are sealed, the lamination cavity is inflated. The gas fills the lamination cavity and compacts the middle part of the glass. Then the next process can be entered.

[0040] Example 2, as Figure 1-Figure 7As shown, a heating plate 2 is fixedly installed on the inner top of the workbench 1, a glass assembly 3 is arranged above the heating plate 2, a bead 4 is arranged inside the workbench 1, a limit plate 5 is fixedly installed on the inner wall of the bead 4, an upper pressing plate 6 is slidably installed on the inner wall of the bead 4, the upper pressing plate 6 is located above the limit plate 5, a silicone plate 7 is fixedly installed on the inner wall of the bead 4, the silicone plate 7 is located above the upper pressing plate 6, a pressing frame 8 is arranged between the glass assembly 3 and the upper pressing plate 6, a vent hole 9 is opened inside the pressing frame 8, and a connecting pipe 10 is fixedly connected to one side of the bead 4, and the connecting pipe 10 is set as a rubber hose;

[0041] The staff selected a piece of ordinary glass with a thickness of 6mm as the lower layer, a piece of coated glass with a thickness of 6mm as the upper layer, and selected PVB film as the middle layer to form a coated glass component 3 sample. The glass component 3 was transported to the surface of the heating plate 2 by the conveying mechanism, and then the pressing frame 8 was placed on the upper edge of the glass component 3. Then the bead 4 was pressed on the surface of the heating plate 2. At the same time, the height of the upper pressing plate 6 from the pressing frame 8 was adjusted so that there was a certain gap between the upper pressing plate 6 and the pressing frame 8, so that a lamination chamber was formed between the upper pressing plate 6, the bead 4, the silicone plate 7 and the heating plate 2. Then the staff exhausted the air in the chamber through the connecting pipe 10 and the vent 9 to form a vacuum state. After the vacuum extraction was completed, the machine heating plate 2 was controlled to heat the glass component 3 so that the glass film reached a softened state. Then the staff controlled the upper pressing plate 6 Move downward until the pressing frame 8 is pressed and the pressure is continuously applied to achieve the edge sealing of the glass. After the edge sealing is completed, the laminating cavity is inflated through the connecting tube 10. After the gas fills the laminating cavity, the middle part of the glass component 3 is compacted. Furthermore, the upper pressing plate 6 can be separated from the pressure strip 4 and moved independently. The independent movement range is about 30mm. When inflating and extracting, the pressure of the upper pressing plate 6 on the pressing frame 8 and the component is maintained to inflate the entire laminating cavity. Air can be filled with other gases. The gas pressure and flow rate can be precisely controlled. The pressure adjustment accuracy is: 0.5%. A pressure difference is formed inside and outside the glass component 3. The pressure difference is used to strongly press the entire component, so that the glass and film are completely integrated. Furthermore, the material of the pressing frame 8 can be set to a steel rectangular frame with the same outer size as the component size and a width of 50mm.

[0042] The coated glass assembly 3 is heated, vacuumed, and then edge-sealed to ensure that there are no bubbles between the coated glass and the film. Air is then introduced, and the air pressure compresses the glass. This air does not damage the coating, but also bonds the coated glass and film together, effectively encapsulating the coated glass assembly 3. The PVB film between the coated glass and ordinary glass effectively enhances the glass's impact resistance. Even if the glass breaks, the film holds the fragments together, preventing them from scattering, thereby improving safety. The vacuum extraction and pressurization process ensures a more uniform fit of the glass assembly 3, preventing the ingress of air and impurities, and ensuring the quality of the laminated glass. This process improves the stability and consistency of the production process, reduces the production of substandard products, and improves production efficiency.

[0044] The dual-purpose pump can realize extraction and inflation operations in the lamination cavity through the connecting pipe 10 , so that the interior of the glass assembly 3 meets the lamination requirements.

[0045] Example 4, as Figures 1-6 As shown, a silicone strip 12 is fixedly installed on the bottom of the pressure strip 4;

[0046] The silicone strip 12 can improve the overall sealing when the pressure strip 4 is attached to the heating plate 2. Furthermore, the silicone strip 12 can ensure that the vacuum degree of the lamination chamber reaches 40-100Pa.

[0047] Example 5, as Figure 1-Figure 7 As shown, a magnetic block 13 is fixedly installed on the surface of the pressure strip 4, a fixing part 14 is fixedly installed on the top of the workbench 1, and an adsorption block 15 is fixedly installed on the side of the fixing part 14 close to the magnetic block 13. Two groups of magnetic blocks 13 and fixing parts 14 are symmetrically arranged. An electric telescopic rod 16 is fixedly installed on the top of the workbench 1, and the output end of the electric telescopic rod 16 is fixedly connected to the upper pressure plate 6. The stability of the pressure strip 4 can be improved by the arrangement of the magnetic block 13 and the adsorption block 15.
