Description

Technical Field

[0001] The invention relates to the technical field of glass deep processing, and more particularly to a special-shaped glass laminating device. Background Art

[0002] With the increasing requirements for energy conservation in green buildings, the application of lightweight building materials U-shaped glass is becoming more and more extensive. In order to further improve safety and energy-saving efficiency, U-shaped glass needs to be laminated in many occasions.

[0003] There are two types of traditional dry lamination. One is to pre-sandwich PVB sheets between double-layer flat glass and then heat them with infrared in an autoclave. It is fixed and formed under high temperature and high pressure. It usually takes several hours to heat thoroughly. It is time-consuming and power-consuming, and the production efficiency is low.

[0004] The other is the vacuum laminating furnace process, which is to place the glass, hot melt adhesive film and glass laminated materials flat in a silicone vacuum bag, and the vacuum bag is pushed into the hot air circulation furnace for heating and temperature rise. At the same time, the vacuum bag is evacuated to discharge the air between the hot melt adhesive film and the glass, and atmospheric pressure is formed inside and outside the vacuum bag to squeeze the glass and the adhesive film to form laminated glass with high bonding strength, high transparency and no bubbles. Due to the use of hot air circulation, the lamination temperature rises slowly, and it also takes several hours to process and produce. Manual disassembly and assembly of vacuum bags is inefficient;

[0005] The laminator abandons heat convection and heat radiation and adopts heat conduction of the vacuum cavity platform inside the laminator. Generally, the processing can be completed in 20 minutes and the production is automated. The disadvantage is that it can only process flat laminated glass or flat photovoltaic panels. When the equipment is started, the oil heating circulation system needs to be preheated for 2 hours to reach the processing temperature of the vacuum cavity platform, which wastes working time.

[0030] Reference Figure 4 As shown, a suction cup arm 22 and a plurality of lifting and conveying components 23 are arranged in the mold turnover area 16. The suction cup arm 22 is used to absorb a closed foaming mold 24 that matches the internal shape of the U-shaped glass 12. The suction cup arm 22 places the closed foaming mold 24 in the unlaminated U-shaped glass 12.

[0035] Reference Figure 4 As shown, the length and width of the heat spreader 28, the upper cover 34 and the sealing frame 38 are consistent. The sealing frame 38 is a square frame with silicone sealing rings 46 embedded on the upper and lower parts. The silicone sealing ring 46 increases the sealing performance.

[0036] Working principle: When the embossed U-shaped glass 12 enters the lamination area 14, the backboard on the backboard reel 17 and the EVA hot melt adhesive film on the EVA hot melt adhesive film reel 18 are laid on the inner surface of the U-shaped glass 12 in sequence. The length of the laid backboard and the EVA hot melt adhesive film is consistent with the inner length of the U-shaped glass 12. Then, the backboard and the EVA hot melt adhesive film are cut off at the end of the U-shaped glass 12 to form a U-shaped glass. When there is no U-shaped glass to be processed in the preheating area 15, the roller conveyor 13 brings the U-shaped glass into the preheating area 15; when the U-shaped glass enters the preheating area 15, the infrared heating tube 19 is started to heat the U-shaped glass. After heating for 5 minutes, the temperature of the U-shaped glass reaches 80 to 90 degrees and the heating is stopped. At this time, the EVA The hot melt adhesive film softens but has not yet melted, and then the roller conveyor 13 brings the preheated U-shaped glass into the mold turnover area 16; the suction cup arm 22 absorbs the closed foaming mold 24. When the U-shaped glass is transferred from the preheating area 15 to the bottom of the suction cup arm 22, the roller conveyor 13 stops running, and the suction cup arm 22 releases the closed foaming mold 24 into the U-shaped glass. The thickness of the closed foaming mold 24 is consistent with the height of the U-shaped glass, so that the laminating machine 25 can laminate to the entire inner surface of the U-shaped glass after filling the U-shaped glass, and the service life of the silicone plate 37 is extended, and then the suction cup arm 22 is retracted, and the lifting and conveying assembly 23 is lifted by the hydraulic cylinder 31 to lift the U-shaped glass with the closed foaming mold 24 0.5 to 2 cm, after the lifting and conveying assembly 23 completes the ascending step, it then lifts up the U-shaped glass and transmits it horizontally to one of the laminators 25, and the U-shaped glass is ready to enter the laminating stage. The U-shaped glass is cross-fed into the two laminators 25 at an interval of 5 minutes; when the U-shaped glass is fed into the laminator 25, the cylinder lift 35 lifts the upper cover 34, the silicone plate 37 and the sealing frame 38 by 10 cm, and then the Teflon conveyor belt 40 starts to operate to deliver the U-shaped glass to the middle of the laminator 25, and the Teflon conveyor belt 40 stops operating, and the cylinder lift 35 drives the upper cover 34, the silicone plate 37 and the sealing frame 38 to descend by 10 cm. When the sealing frame 38 presses the soaking plate 28, the cylinder lift 35 stops working, and at this time, two closed spaces are formed above and below the silicone plate 37, and the upper and lower air inlet valves 44 on the upper cover 34 and the soaking plate 28 are closed, and the upper and lower vacuum valves 45 are opened to start exhausting air to form two vacuum layers, which are the upper vacuum layer and the lower vacuum layer. The upper vacuum layer and the lower vacuum layer are connected, and the power of the heating plate 29 is also turned on to start heating. At this time, the silicone plate 37 is not laminated and it is easy to discharge the gas in the U-shaped glass. About 1 minute later, the upper and lower vacuum layers reach below 200 Pa, and the temperature of the U-shaped glass rises to above 100 degrees. The upper vacuum valve 43 is closed and the upper air inlet valve 42 is opened at the same time. The upper vacuum layer is inflated to cause the silicone plate 37 to sink and start laminating the U-shaped glass. The heating plate 29 continues to work and heats to 140 degrees and then operates at a constant temperature. After laminating for 8 to 9 minutes, the heating plate 29 is stopped, the lower vacuum valve 45 and the upper air inlet valve 42 are closed, and the upper vacuum valve 43 and the lower air inlet valve 44 are opened. After the silicone plate 37 rises, the cylinder lift 35 is started, and the upper cover 34 of the laminator 25 is lifted by 10 cm. Then the Teflon conveyor belt 40 is started to convey the laminated U-shaped glass 12 to the mold turnover area. At the same time, the lifting and lowering conveying component 23 is lifted and reversely drives the laminated U-shaped glass 12 to the bottom of the suction cup boom 22. The lifting and conveying assembly 23 sinks, the suction cup arm 22 descends to absorb the closed foaming mold 24 and then rises for standby use. The U-shaped glass 12 after lamination is transported forward by the roller assembly line together with the U-shaped glass behind it, completing the continuous lamination process.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
