Description

Technical Field

[0001] The invention relates to the technical field of tempered laminated glass production equipment, in particular to a special device for producing bent tempered laminated glass. Background Art

[0002] Laminated tempered glass is a composite glass product made of two or more pieces of glass sandwiched with one or more layers of organic polymer interlayer, bonded together after special processing. PVB film has good transparency, weather resistance and adhesion, and is often used in laminated glass manufacturing to improve safety and sound insulation performance.

[0003] In the production of bent tempered laminated glass, film bonding is a key step; poor film bonding quality will reduce the strength and safety of the glass, and bubbles or impurities will also affect the transparency and appearance quality of the glass.

[0004] In the existing special equipment for producing bent tempered laminated glass, the glass and the film are usually placed in a specific fixture or mold during the bonding process, and then the film and the glass are bonded together by heating and pressurizing. However, in the actual production process, there are easily bubbles, impurities or loose bonding between the film and the glass. The main reasons are as follows:

[0005] 1. The structure of the existing fixture or mold is unreasonable. Due to the lack of sufficient exhaust channels or improper exhaust port position, the air cannot be discharged smoothly during the gluing process, and is trapped between the film and the glass to form bubbles.

[0007] 3. The existing fixtures or molds do not work well with the heating structure, and the PVB film and curved tempered laminated glass before bonding are not heated in a gradient manner. As a result, the following problems will occur: the temperature difference between the glass and the film is large during the bonding process, resulting in poor bonding quality, bubbles, debonding and other problems; the temperature difference between the glass is large during the bonding process, resulting in glass deformation, affecting product quality; the temperature difference between the glass and the film is large during the bonding process, resulting in extended bonding time and reduced production efficiency.

[0051] Embodiment 3

[0052] See also Figure 1-10 The present invention provides a technical solution: a special device for producing bent tempered laminated glass. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0053] As a further limitation of the present invention, the gas exchange mechanism 32 includes a hot air component 33 and an exhaust component 34, the hot air component 33 and the exhaust component 34 are respectively connected to a hot air switch 35 and an exhaust switch 36, the hot air switch 35 and the exhaust switch 36 are both light-sensing switches, the hot air switch 35 and the exhaust switch 36 are installed on the inner wall of the tank body of the lower mold plate 4, and the hot air switch 35 is installed on the upper part of the exhaust switch 36;

[0054] The light sensing switch is composed of a light sensor, a control circuit, a switch element, a housing and an interface, and its internal connection is based on the existing technology. When the grabbing plate 24 moves downward into the groove of the lower mold plate 4, the light intensity changes, and the light sensor generates an electrical signal change. The control circuit judges based on the preset threshold and outputs a control signal to turn on the switch element, thereby connecting the circuit of the hot air switch 35 and making the air pump 37 work.

[0055] The hot air assembly 33 includes an air pump 37, which is installed on the cabinet 1 with the air inlet end facing outward, and a dust filter box 38 is provided at the air inlet end.

[0056] During operation, the grabbing plate 24 first extracts the first piece of curved tempered glass, and then lowers it to the bottom of the groove of the lower mold plate 4. Then, the grabbing plate 24 grabs the PVB film and moves it above the lower mold plate 4 again. When the grabbing plate 24 descends along the groove of the lower mold plate 4, the hot air switch 35 at the top is triggered first, and the air pump 37 draws external air, which is heated by the air heating cylinder 39 and then transported to the inside of the groove of the lower mold plate 4, so that the first piece of curved tempered glass inside the groove of the lower mold plate 4 and the PVB film entering are heated, so that the PVB film is softened, which is conducive to the close fitting of the PVB film and the first piece of curved tempered glass. After the PVB film is heated and softened, the grabbing plate 24 continues to descend, triggering the exhaust switch 36, and at the same time closing the hot air switch 35. The suction end of the vacuum pump 41 passes through the exhaust pipe 4 2. Extract the air inside the groove of the lower mold plate 4 to avoid interference from dust and impurities in the air, so that negative pressure is formed between the PVB film and the first curved tempered glass, which is conducive to the close adhesion of the softened PVB film and the curved tempered glass, so as to ensure that the film is in full contact with the curved glass and remove bubbles. Then, the grab plate 24, driven by the drive seat 16, grabs the second curved tempered glass again, repeats the above steps, and triggers the hot air switch 35 and the exhaust switch 36 in sequence again to achieve heating of the PVB film and the second curved tempered glass, which is conducive to the close combination of the upper surface of the softened PVB film and the second curved tempered glass to improve the adhesion and bonding effect. At the same time, with the cooperation of the exhaust component 34, air is extracted and bubbles are removed to ensure that the film is in full contact with the curved glass.

[0057] After the materials are prepared, the clamping mechanism 2 is started, and the upper mold plate 3 moves downward into the groove body of the lower mold plate 4. The hot air component 33 works first. Before bonding, the bent tempered glass and the PVB film can be preheated. Preheating can help reduce the temperature gradient and make it easier for the glass and the film to receive uniform heat during the bonding process. Then the exhaust component 34 works to extract air, reduce dust, and form a negative pressure tight bonding effect. Further, the first heating component 9 inside the upper mold plate 3 and the lower mold plate 4 of the clamping mechanism 2 starts to work, and heats the upper and lower pieces of bent tempered glass at the same time to ensure uniform heating. Finally, the upper mold plate 3 continues to be pressed down by the cylinder 5 under the push of the piston rod. Since the internal shapes of the upper mold plate 3 and the lower mold plate 4 are the same as those of the bent tempered glass, during the bonding process, pressure is evenly applied to ensure that the film is in full contact with the bent glass, eliminate bubbles, and make the PVB film fit tightly between the two pieces of bent tempered glass, thereby improving the bonding quality of the bent tempered laminated glass.
