A three-silver interlayer exempts film production process and equipment

Abstract

This invention relates to the field of glass processing technology, specifically a triple silver laminate production process and equipment that eliminates the need for film removal. The process includes loading an outdoor glass sheet onto the adhesive end of a release liner. After the glass sheet is identified by a loading identification end, an execution signal is sent to the production equipment. The production equipment, configured for triple silver laminate production, attaches the release liner around the adhesive surface of the outdoor glass sheet. The release liner is then pressed flat on all four sides and its corners are tightened to ensure stable adhesion. The release liner serves as a covering surface for the triple silver film during application. By coating the entire triple silver film onto the release liner, the release liner can be removed before lamination to remove the triple silver film layer around the glass surface, eliminating the need for a separate film removal process and preserving a clean and smooth glass surface.

Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically to a triple silver interlayer film-free production process and equipment. Background Technology

[0002] When a low-emissivity (LOW-E) film is coated with a silver layer, incomplete film removal can affect the adhesion of the film. Therefore, edge removal is necessary to ensure proper adhesion and protect the film layer. While existing machine-based film removal methods offer high integrity, they can compromise the smoothness of the glass surface, leading to risks of air bubbles and delamination after lamination. This increases the defect rate and scrap rate during lamination film removal and makes it difficult to meet national standards in boiling tests. Summary of the Invention

[0003] To address the problems in the prior art, this invention provides a process and equipment for producing triple silver sandwich membranes that eliminate the need for removal.

[0004] The technical solution adopted by this invention to solve its technical problem is: a triple silver interlayer film-free production process, comprising the following steps: Step S1: Place the outdoor glass layer onto the adhesive end of the isolation strip. After the glass layer recognition end confirms that the glass has reached the processing position, send an execution signal to the production equipment. Step S2: The triple silver laminate production equipment set by the production equipment attaches an isolation strip around the perimeter of the outdoor glass layer bonding surface. After attaching the isolation strip, the outdoor glass layer bonding surface is flattened on all four sides and the corners are tightened to ensure that the perimeter of the bonding surface is flush and does not affect the sputtering atmosphere when the glass layer is sent into the coating chamber. The width of the isolation strip is between 10 and 20 mm. Step S3: Apply the triple silver layer to the surface of the isolation strip. After the application is completed, tear off the isolation strip along the four corners of the outdoor glass layer. This will cause the remaining triple silver layer on the surface of the isolation strip to fall off simultaneously with the tearing of the isolation strip, leaving the outdoor glass layer with a clean and flat surface. Step S4: Bond a PVB interlayer between the indoor glass layer and the outdoor glass layer with the triple silver layer, and then send the indoor glass layer and the outdoor glass layer into the lamination chamber for lamination processing to obtain triple silver laminated glass. The production equipment for the triple silver laminate manufacturing process includes a strip loading mechanism, a strip end verification mechanism, a drive transmission roller, a four-sided pressing execution component, a four-sided corner pressing component, and a bonding and unloading conveyor. The drive transmission roller is positioned at the upper end of the outdoor glass layer's strip adhesion end, and the bonding and unloading conveyor is positioned at the lower end of the outdoor glass layer's strip adhesion end. The strip loading mechanism is located on one side of the drive transmission roller and is used to output the strip to be coated on the outer surface of the outdoor glass layer, so that the strip is distributed on all four sides and covers the outer surface of the outdoor glass layer. The strip end verification mechanism is used to verify the completion of the strip covering the outer surface of the outdoor glass layer. The four-sided pressing execution component is used to flat press the adhesive surface of the outdoor glass layer with the strip attached on all four sides. The four-sided corner pressing component is used to tighten the strip attached to the corners of the outdoor glass layer during the flat pressing process. The bonding and unloading conveyor is used to unload the strip after the strip coating is completed.

[0005] Preferably, the isolation belt conveyor mechanism includes a roller drive control, a translational transmission channel, and a bonding guide pusher. The roller drive control, the translational transmission channel, and the bonding guide pusher are all mounted on the upper end of the drive transmission roller. The bonding guide pusher is installed at the output end of the translational transmission channel. The roller drive control is used to transmit the isolation belt to the translational transmission channel, and guide the isolation belt to be placed on the outdoor glass layer at the upper end of the drive transmission roller through the translational transmission channel.

[0006] Preferably, the upper belt end approval mechanism includes an upper belt image analysis module and a PLC controller. The PLC controller is located on one side of the drive transmission roller. The PLC controller is connected to the roller drive control, the upper belt image analysis module, and the drive transmission roller. The upper belt image analysis module is used to monitor the completion of the four-sided bonding of the outdoor glass layer after the isolation strip is coated on the upper end of the drive transmission roller.

[0007] Preferably, the four-sided pressing execution assembly includes a circumferential rotation drive, a motion path lifting column, a first steering knuckle, and a second steering knuckle. The circumferential rotation drive is disposed at the bottom of the drive transmission roller. The output end of the circumferential rotation drive is connected to the first steering knuckle through the second steering knuckle. The output end of the first steering knuckle is connected to the four-sided corner pressing assembly through the motion path lifting column. The circumferential rotation drive is used to drive the second steering knuckle and the first steering knuckle to move along the outer periphery of the outdoor glass layer at the upper end of the drive transmission roller. A mounting bracket plate is fixedly connected to the bottom of the circumferential rotation drive, and a bottom support is fixedly connected to the top of the mounting bracket plate.

[0008] Preferably, the four-sided corner pressing assembly includes a side-face transmission connecting seat, an arc-shaped guide seat, a bonding pressure roller, and an elastic extension. The side-face transmission connecting seat is rotatably connected to the top of the lifting column of the motion path. The arc-shaped guide seat is rotatably connected to the inner side of the side-face transmission connecting seat. The elastic extension is disposed on the inner side of the side-face transmission connecting seat, and both ends of the elastic extension are fixedly connected to the arc-shaped guide seat and the side-face transmission connecting seat, respectively. The bonding pressure roller is fixedly disposed on the inner side of the arc-shaped guide seat.

[0009] Compared to existing technologies, the advantages of this invention are as follows: The isolation strip is attached to the perimeter of the outdoor glass layer adhesive surface using a triple silver lamination production equipment. The attached isolation strip is then pressed flat on all four sides and its corners are tightened, ensuring stable attachment to the outdoor glass layer adhesive surface. The isolation strip serves as the covering surface around the glass during triple silver film application. By coating the entire triple silver film onto the isolation strip, the isolation strip can be removed before lamination to remove the triple silver film layer around the glass surface. This eliminates the need for a film removal process, preserving a clean and flat glass surface. This facilitates subsequent lamination. Compared to existing film removal processes, this process avoids incomplete film removal and damage to the glass surface flatness. It also reduces water and electricity consumption during film removal, shortening the production cycle required by conventional film removal processes. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-4 As shown, the production process of a triple silver interlayer membrane without removal according to the present invention includes the following steps: Step S1: The outdoor glass layer is attached to the adhesive end of the insulating tape. After the glass is identified by the attachment end, an execution signal is sent to the production equipment. In this embodiment, the adhesive end of the insulating tape is equipped with production equipment used in the triple silver interlayer production process. After the attachment identification section detects the sensing signal generated by the glass attachment, it can send an adhesive tape operation signal to the production equipment.

[0015] Step S2: The triple-silver lamination production equipment, as set by the production equipment, applies an isolation strip around the perimeter of the outdoor glass laminate bonding surface. After applying the isolation strip, the bonding surface of the outdoor glass laminate is flattened on all four sides and the corners are tightened to ensure that the perimeter of the bonding surface is flush and does not affect the sputtering atmosphere when the glass layer is fed into the coating chamber. The width of the isolation strip is between 10 and 20 mm. The production equipment is mainly used for flattening the four sides and tightening the corners of the outdoor glass laminate bonding surface after applying the isolation strip. Compared with existing film removal processes, the production equipment used in this process can automate and complete the application of the isolation strip more quickly.

[0016] Step S3: Apply the triple silver layer to the surface of the isolation strip. After the coating is completed, peel off the isolation strip along the four corners of the outdoor glass layer. The remaining triple silver layer on the isolation strip surface will fall off simultaneously with the removal of the isolation strip, leaving a clean and flat surface on the outdoor glass layer. In this embodiment, after the coating process, the film layer is coated on the isolation strip. After peeling off the isolation strip, a clean and flat surface is left around the edges. This avoids incomplete film removal and damage to the flatness of the glass surface. While reducing the energy consumption of film removal, it can also effectively shorten the production cycle compared to the film removal process. It can avoid increasing the time spent on site, which would affect the processability of the triple silver product, thereby improving the first-pass yield of the product.

[0017] Step S4: Lay a PVB interlayer between the indoor glass layer and the outdoor glass layer with the triple silver layer, and then send the indoor glass layer and the outdoor glass layer into the lamination chamber for lamination processing to obtain triple silver laminated glass.

[0018] In one optional embodiment of this example, the production equipment for the triple silver interlayer manufacturing process includes an isolation strip loading mechanism 1, an upper strip end verification mechanism 2, a drive transmission roller 3, a four-sided pressing execution component 4, a four-sided corner pressing component 5, and a bonding and unloading conveyor end 6. The drive transmission roller 3 is located at the upper position of the outer glass layer isolation strip adhesion end, and the bonding and unloading conveyor end 6 is located at the lower position of the outer glass layer isolation strip adhesion end. The isolation strip loading mechanism 1 is located on one side of the drive transmission roller 3. The isolation strip loading mechanism 1 is used to output the isolation strip to be coated on the outer surface of the outer glass layer, so that the isolation strip is distributed on all four sides and covers the outer surface of the outer glass layer. The upper strip end verification mechanism 2 is used to verify the completion of the isolation strip after it covers the outer surface of the outer glass layer. The four-sided pressing execution component 4 is used to flat press the adhesive surface of the outer glass layer with the isolation strip attached on all four sides. The four-sided corner pressing component 5 is used to tighten the isolation strip attached to the corners of the outer glass layer during the four-sided flat pressing process. The bonding and unloading conveyor end 6 is used to unload the isolation strip after the coating is completed.

[0019] In this embodiment, the present invention comprises a production equipment for the triple silver lamination process, consisting of an isolation strip mounting mechanism 1, an upper strip end verification mechanism 2, a drive transmission roller 3, a four-sided pressing execution component 4, a four-sided corner pressing component 5, and a bonding lower sheet transmission end 6. This production equipment completes the attachment of the isolation strip to the bonding surface of the outdoor glass. The isolation strip is attached to the perimeter of the bonding surface of the outdoor glass layer, and the attached isolation strip is flattened on all four sides and the corners are tightened to ensure stable attachment to the bonding surface of the outdoor glass layer. The isolation strip serves as the covering surface around the glass during triple silver film attachment. By coating the entire triple silver film onto the isolation strip, the isolation strip can be removed before lamination to remove the triple silver film layer around the glass surface. This eliminates the need for a film removal process, preserving a clean and flat glass surface, which is convenient for subsequent lamination. Compared with existing film removal processes, this process avoids incomplete film removal and damage to the flatness of the glass surface. It also reduces water and electricity consumption during film removal and shortens the production cycle required by conventional film removal processes.

[0020] In one optional embodiment of this embodiment, the isolation belt feeding mechanism 1 includes a roller drive control 11, a translational transmission channel 12, and a bonding guide push head 13. The roller drive control 11, the translational transmission channel 12, and the bonding guide push head 13 are all mounted on the upper end of the drive transmission roller 3. The bonding guide push head 13 is installed at the output end of the translational transmission channel 12. The roller drive control 11 is used to transmit the isolation belt to the translational transmission channel 12, and guide the isolation belt to be placed on the outdoor glass layer at the upper end of the drive transmission roller 3 through the translational transmission channel 12.

[0021] In this embodiment, the roller drive control 11 consists of a take-up roller and a servo motor that drives the take-up roller. After the isolation tape roll is placed outside the roller drive control 11, the front end of the isolation tape is stretched and crosses the inside of the roller drive control 11 to reach the position above the drive transmission roller 3. When the isolation tape comes out through the inside of the translational transmission channel 12 via the roller drive control 11, the passing height of the isolation tape is limited by the conforming guide push head 13, so that the isolation tape covers the glass surface above the drive transmission roller 3 more smoothly, which can improve the operational adaptability during subsequent four-sided flat pressing and tightening.

[0022] In an optional embodiment of this example, the upper belt end approval mechanism 2 includes an upper belt image analysis module 21 and a PLC controller 22. The PLC controller 22 is located on one side of the drive transmission roller 3. The PLC controller 22 is connected to the roller drive control 11, the upper belt image analysis module 21 and the drive transmission roller 3. The upper belt image analysis module 21 is used to monitor the completion of the four-sided attachment of the outdoor glass layer after the isolation strip is coated on the upper end of the drive transmission roller 3.

[0023] In this embodiment, the PLC controller 22 is used to control the loading and unloading operations of the glass before and after the glass is attached with the isolation tape. Simultaneously, the PLC controller 22 controls the upper image analysis module 21 to verify whether the glass is accurately positioned at the angle of the drive transmission roller 3 after the glass is loaded to the upper position of the drive transmission roller 3. It is also used to verify whether the isolation tape is aligned with the glass surface after the isolation tape is attached to the upper end of the drive transmission roller 3. The upper image analysis module 21 serves as the imaging end, connecting to an external image analysis terminal to record images for analysis.

[0024] In an optional embodiment of this example, the four-sided pressing execution component 4 includes a circumferential rotation drive 41, a motion path lifting column 42, a first steering knuckle 43, and a second steering knuckle 44. The circumferential rotation drive 41 is disposed at the bottom of the drive transmission roller 3. The output end of the circumferential rotation drive 41 is connected to the first steering knuckle 43 through the second steering knuckle 44. The output end of the first steering knuckle 43 is connected to the four-sided corner pressing component 5 through the motion path lifting column 42. The circumferential rotation drive 41 is used to drive the second steering knuckle 44 and the first steering knuckle 43 to move along the outer periphery of the upper outdoor glass layer of the drive transmission roller 3. The bottom of the circumferential rotation drive 41 is fixedly connected to a mounting bracket plate 45, and the top of the mounting bracket plate 45 is fixedly connected to a bottom support 46.

[0025] In this embodiment, the mounting plate 45 with bracket is used to assemble the circumferential rotation drive component 41 to the bottom of the drive transmission roller 3. The top surface of the bottom support 46 (which is a vacuum suction cup) is at the same height as the transmission surface of the drive transmission roller 3. After the glass sheet reaches the upper end of the drive transmission roller 3, the glass is fixed by the bottom support 46. A rotating shaft is provided between the second steering knuckle 44 and the first steering knuckle 43. The second steering knuckle 44 is used to control the rotation angle of the first steering knuckle 43. A rotating shaft is provided between the first steering knuckle 43 and the motion path lifting column 42. The first steering knuckle 43 is used to allow the four-sided corner pressing assembly 5 to move in any direction along the outer periphery of the glass when the motion path lifting column 42 moves along the outer periphery of the glass, ensuring that the four-sided corner pressing assembly 5 is attached to the outer periphery of the glass. When the four-sided corner pressing assembly 5 reaches the glass corner position, the second steering knuckle 44 is driven by the circumferential rotation drive 41 to move around the mounting bracket disc 45. Then, the first steering knuckle 43 is driven by the second steering knuckle 44 to rotate along its rotation axis connection position, thereby changing the rotation angle of the four-sided corner pressing assembly 5.

[0026] In one optional embodiment of this example, the four-sided corner pressing assembly 5 includes a side surface transmission connecting seat 51, an arc-shaped guide seat 52, a bonding pressure roller 53, and an elastic extension 54. The side surface transmission connecting seat 51 is rotatably connected to the top of the lifting column 42 of the motion path, the arc-shaped guide seat 52 is rotatably connected to the inner side of the side surface transmission connecting seat 51, the elastic extension 54 is disposed on the inner side of the side surface transmission connecting seat 51, and both ends of the elastic extension 54 are fixedly connected to the arc-shaped guide seat 52 and the side surface transmission connecting seat 51, respectively. The bonding pressure roller 53 is fixedly disposed on the inner side of the arc-shaped guide seat 52.

[0027] In this embodiment, the edge transmission connecting seat 51 is rotatably arranged at the upper end of the lifting column 42 along the movement path, and the arc-shaped guide seat 52 is rotatably arranged at the inner side of the edge transmission connecting seat 51. When the circumferential rotation drive member 41 drives the lifting column 42 along the outer periphery of the glass at the upper end of the drive transmission roller 3, the arc-shaped guide seat 52 moves around the edge of the glass. The isolation strip is attached to the edge of the glass by the rolling pressure of the adhesion pressure roller 53, so as to achieve the purpose of flat pressing on all four sides of the glass after the isolation strip is attached. At the same time, when the arc-shaped guide seat 52 moves to the edge of the glass and reaches the corner of the glass, the elastic extension part 54 is compressed and retracts, so that the arc-shaped guide seat 52 and the edge transmission connecting seat 51 can rotate freely to fit the corner of the glass. Furthermore, as the arc-shaped guide seat 52 gradually moves to the flat edge of the glass, the elastic extension 54 resets the arc-shaped guide seat 52 to rotate back to its original position and remain parallel to the flat edge of the glass, ensuring that the bonding roller 53 re-aligns with the required safe area of ​​the isolation strip, thereby ensuring the stability of the isolation strip's bonding surface.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
