[0031] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0032] Figure 1 The double-laminated flanging insulating glass processing method shown comprises the following steps:

[0033] S1: Loading matching glass and coated glass on the laminated glass production line;

[0034] S2: Remove the film from the coated glass; clean the matching glass and the coated glass;

[0035] S3: Assembling the matching glass, the coated glass and the aluminum frame;

[0036] S4: Roll and glue the assembled matching glass, coated glass and aluminum frame.

[0037] The present application develops a new processing operation flow of double-laminated flanging insulating glass, which specifically includes loading, film removal, cleaning, framing, joining, rolling, gluing and storage of lower sheets; fully utilizing the laminated glass production line to realize the automation of super-large and super-thick glass production; the laminated glass production line continues to carry out the production operation of laminated glass under normal circumstances; when super-large and super-thick flanging glass needs to be processed, the processing method can be switched to realize automatic and efficient processing of super-large and super-thick flanging glass; no customized special processing equipment is required, which greatly reduces the production cost.

[0038] S3 includes:

[0039] S31: The cleaned matching glass is transferred to the assembly section; the matching glass is lifted by the gantry crane suction cup;

[0040] S32: transferring the cleaned coated glass to the assembly section; connecting the coated glass to the aluminum frame;

[0041] S33: Hang the matching glass to the top of the aluminum frame; align the matching glass with the edge of the aluminum frame, measure the position of the floating edge and assemble them.

[0042] The fluttering of insulating glass is a special processing form, in which one piece of glass extends outward relative to the other on the plane; it breaks the tradition in terms of aesthetics and adds a sense of layering; it can increase the lighting area, improve indoor brightness and save energy; the warm edge technology can also improve the thermal insulation performance and avoid condensation on the edge of the inner glass; in S31, the matching glass is cleaned and transferred to the assembly section, and the gantry crane suction cup is used to lift the matching glass from the work surface of the assembly section to the air for standby use; in S32, after the cleaned coated glass is transferred to the assembly section, the coated glass is first bonded to one side of the aluminum frame with butyl glue, and then the other side of the aluminum frame is placed vertically upward; in S33, the matching glass is first lowered to a certain height so that the matching glass is close to the fitting position of the aluminum frame; at this time, according to the order production requirements, the matching glass is aligned with the edge of the aluminum frame, the fluttering position is measured for assembly, and high-precision assembly operation is achieved.

[0043] In S3, the joining section is set in the mezzanine clean room; in S31, the gantry crane suction cup lifts the matching glass to 150 mm away from the work surface; in S33, the matching glass is suspended 10 mm from the top of the aluminum frame, and after aligning the matching glass with the edge of the aluminum frame, the floating edge position is measured with a steel ruler for joining.

[0044] Maintaining a dust-free environment in the interlayer clean room can effectively prevent the hollow layer between the matching glass and the coated glass from being contaminated by dust, effectively improving the product yield; the matching glass is lifted to 150mm from the work surface, which can facilitate the lowering operation of the matching glass; hanging it 10mm from the top of the aluminum frame can facilitate manual alignment of the matching glass with the edge of the aluminum frame, measure the floating edge position for joining, and achieve high-precision joining operations.

[0045] S4 includes:

[0046] S41: pre-adjust the pressing height of the flat press according to the overall thickness of the assembled glass, coated glass and aluminum frame; set the temperature of the flat press to a specified temperature; place the assembled glass, coated glass and aluminum frame at the bottom of the flat press, and start the flat press for rolling.

[0047] The matching glass, coated glass and aluminum frame are bonded together to form an integral glass. The pressing height of the flat press is pre-adjusted according to the thickness of the integral glass. After the setting is completed, the flat press can press the integral glass downward so that the butyl adhesive on the aluminum frame is evenly coated with the matching glass and coated glass after being pressed. Heating can enhance the fluidity of the butyl adhesive on the aluminum frame to ensure the uniformity of the coating after the butyl adhesive is pressed.

[0048] In S41, the pressing height of the flat press is adjusted to be 2 mm smaller than the overall thickness of the assembled glass, coated glass and aluminum frame after assembly; the temperature of the flat press is set to 35°C to 50°C.

[0049] The matched glass, coated glass and aluminum frame are bonded together to form an integral glass; the height of the press after pressing is preset to be less than the thickness of the integral glass, which can achieve effective rolling and ensure the uniformity of the coating of the butyl rubber after being pressed; the temperature of the press is set at 35℃~50℃, which can effectively enhance the fluidity of the butyl rubber and enhance the rolling effect of the press.

[0050] In S1, the matched glass and the coated glass are transported to the processing station by rollers; the matched glass and the coated glass are sucked by a mechanical arm with a suction cup and laid flat.

[0051] The roller conveyor of the laminated glass production line can realize the transportation of matching glass and coated glass; the robotic arm with suction cup can suck up the matched glass and coated glass that have been transported to the place and lay them flat, thereby realizing automatic loading, facilitating subsequent operations and effectively improving work efficiency.

[0052] S2 includes:

[0053] S21: Move the coated glass to the universal table; set the film removal width according to the processing accuracy requirements and perform film removal; measure the width after film removal, and check the film removal quality and straightness;

[0054] S22: The height of the laminated cleaning machine is adjusted, and the matched glass and the coated glass after film removal are moved to the laminated cleaning machine for cleaning.

[0055] The coated glass is de-filmed according to the needs of order processing; removing part of the coating layer of the coated glass, especially in the parts that may contact electrolytes or humid environments, can reduce the existence of potential difference, destroy the conditions for electrochemical corrosion, and thus reduce the risk of oxidation, effectively extending the service life of the glass; in S21, a universal stage is used for manual de-filming; after the de-filming is completed, the coated glass is inspected for de-filming to ensure the quality of de-filming; in S22, a laminated cleaning machine is used to clean the matching glass and the coated glass after de-filming, which can remove impurities such as dust, oil, debris, and residual chemicals on the surface of the matching glass and the coated glass during the production and processing process, thereby improving the cleanliness of the glass; ensuring that subsequent processing steps such as lamination and bonding can proceed smoothly, enhancing the bonding effect between the sealant and the glass, and ensuring product quality; it can also prevent impurities from affecting the optical properties and aesthetics of the glass, effectively extending the service life of the glass.

[0056] In S21, the film removal width is set to the sum of the glue depth and the edge width plus 7 mm; white paper is used to check the film removal quality and whether the coated glass is straight after the film removal is completed.

[0057] The staff manually uses A4 white paper to test the film removal quality of the coated glass; the A4 white paper is placed on the bottom of the coated glass to observe the light transmittance and light transmittance uniformity of the coated glass; at the same time, the staff manually fits the edges of the A4 white paper to the edges of the coated glass, and visually checks whether the edges of the A4 white paper fit with the edges of the coated glass, and can check whether the edges of the coated glass are straight.

[0058] In S3, both sides of the aluminum frame are coated with butyl glue.

[0059] Butyl rubber has excellent sealing properties and can prevent air and water vapor from penetrating. It has good bonding properties and is firmly attached to the aluminum frame. It has strong aging resistance and can adapt to a variety of environments. It is easy to construct and operate and can adapt to different aluminum frames. The staff manually applies butyl rubber on both sides of the aluminum frame. The coating thickness of butyl rubber needs to be set strictly according to the production specifications, and the butyl rubber needs to be evenly applied at various coating points on the aluminum frame.

[0060] In S4, the assembled glass is transported to the universal table, glue is applied manually, and the corners of the glass are flattened with corner pressing cotton; the glass is placed parallel to the ground with a crane and padded with square wooden boards to wait for the glue to dry.

[0061] The glass is transferred to the universal table and glued manually. The sealing quality is required to be smooth and without waves, and the corners are flattened with corner pressing cotton. Finally, a crane is used to place the glass parallel to the ground and a square wooden board is used as a spacer to wait for the glue to dry.
