Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to a continuous forming apparatus for fireproof architectural glass. Background Technology

[0002] Architectural glass is an indispensable material in modern architecture, widely used in curtain walls, doors and windows, partitions, and skylights. With increasingly stringent building fire protection design codes, the fire resistance requirements for architectural glass are constantly rising. Currently, composite fire-resistant glass, due to its ability to effectively block flames, heat radiation, and toxic fumes in a fire, has become the preferred safety material for high-rise buildings and public places. This type of fire-resistant glass is typically manufactured by injecting or coating a transparent fire-resistant adhesive between two or more glass substrates, followed by a curing process.

[0003] In the prior art, continuous forming apparatuses for fire-resistant glass have been developed. For example, a known forming apparatus includes a base, conveyor rollers, a coating mechanism, a defoaming mechanism, and a drying channel. The glass substrate is carried by the conveyor rollers and passes through each station sequentially. The coating mechanism evenly applies fire-retardant adhesive to the glass surface, followed by a defoaming treatment to remove air bubbles from the adhesive layer. Finally, the glass is heated and cured in the drying channel. The defoaming mechanism typically employs static natural defoaming or mechanical rolling, and the drying channel is usually set as a single high-temperature constant-temperature zone.

[0004] However, the aforementioned existing devices have the following significant technical defects: First, the defoaming mechanism lacks an active and uniform action method. Static defoaming is extremely time-consuming and difficult to completely eliminate micro-bubbles. Mechanical roller pressing easily causes scratches or extrusion deformation on the adhesive layer surface, affecting the optical quality and fireproof and heat-insulating performance of the finished product. Second, the device lacks centering and adaptive adjustment functions during the glass substrate conveying process. The glass is prone to skew on the roller conveyor, leading to inaccurate positioning of subsequent coating, defoaming, and curing processes. Especially when the glass width changes, the working width of the defoaming mechanism cannot be adaptively adjusted, resulting not only in energy waste and uneven defoaming but also in stress concentration or adhesive wrinkling at the glass edges, significantly reducing the product qualification rate. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous fireproof forming apparatus for architectural glass to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A continuous fire-resistant molding device for architectural glass includes a base, a side control unit, and a centering monitoring component. The upper surface of the base is provided with a roller conveyor for carrying and transporting a glass substrate. Along the direction of transporting the glass substrate via the roller conveyor, a coating component, a defoaming component, and a drying and curing structure are sequentially arranged. One end of the coating component is connected to the side control unit and is used to coat the upper surface of the glass substrate with a fire-resistant adhesive. The drying and curing structure is located at the downstream end of the roller conveyor and is used to heat and cure the glass substrate coated with the fire-resistant adhesive to form a fire-resistant glass substrate. Multiple defoaming components are distributed between the coating component and the drying and curing structure along the transport direction of the glass substrate, with their working surfaces facing the upper surface of the glass substrate. They are used to apply ultrasonic vibration to the fire-resistant adhesive to cause bubbles to rise and burst. The centering monitoring component is disposed above the defoaming component. It has two branches and extends along the conveying direction of the glass substrate to the front end of the roller conveyor component. The two branches can move along the width direction of the roller conveyor component to ensure that the glass substrate is in the center position by moving it laterally. The middle of the two branches is connected to each of the defoaming components to adjust the width of the ultrasonic vibration applied by the defoaming components.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative embodiment: the bubble removal assembly includes a bubble removal transverse frame, a power supply, and ultrasonic transducers. The bubble removal transverse frame is transversely arranged above the roller conveyor component, with one end connected to the roller conveyor component via an extension connecting arm. The ultrasonic transducers are multiple and evenly distributed along the width of the roller conveyor component on the end face of the bubble removal transverse frame facing the glass substrate. Each ultrasonic transducer has an electric mounting base on its non-working end face. The power supply is provided on the extension connecting arm and is connected to each of the electric mounting bases via a parallel circuit.

[0008] In one alternative: the centering monitoring component contacts the circuit contacts on the electric base when it passes the surface of the electric base, thereby switching the working state of the ultrasonic transducer and adjusting the ultrasonic vibration range of the entire bubble removal assembly.

[0009] In one alternative: the ultrasonic frequencies of the plurality of bubble removal components are distributed in a gradient decreasing manner along the conveying direction of the glass substrate, and the ultrasonic frequency range of the bubble removal components is 20kHz-80kHz.

[0010] In one alternative embodiment: a lifting assembly is provided on the side control body. The lifting assembly includes a lifting connecting frame and at least one lifting cylinder. The lifting cylinder is fixedly connected to the ends of the plurality of bubble removal components and is vertically slidably connected to the outer wall of the side control body. The lifting cylinder is disposed on the side control body, and its telescopic end is connected to the lifting connecting frame. It is used to drive the plurality of bubble removal components to move vertically to adjust the distance between their working surfaces and the upper surface of the glass substrate.

[0011] In one alternative: the distance between the working surface of the defoaming component and the upper surface of the glass substrate is 5mm-30mm.

[0012] In one alternative embodiment: the coating assembly includes a coating housing, a main pipeline, and a liquid injection assembly. The coating housing is arranged along the width direction of the roller conveyor component, and one end of it is connected to the side control body via an external connector. The main pipeline is disposed inside the coating housing, and multiple control valves are evenly distributed on it. The multiple control valves divide the main pipeline into multiple adhesive pipelines, and each adhesive pipeline is provided with a coating head facing the glass substrate. The liquid injection assembly is used to inject fire-retardant adhesive into the main pipeline, and the control valves are used to control the on / off state of each adhesive pipeline to adapt to the width of the glass substrate.

[0013] In one alternative embodiment: the centering monitoring component includes a centering drive unit and two centering adjustment modules. The centering drive unit includes a centering screw, a centering motor, and two centering slides. The centering screw is rotatably mounted on the top of the drying and curing structure, with its axis aligned with the width direction of the roller conveyor component. The centering screw is a left- or right-handed screw, with its end connected to the output end of the centering motor. The two centering slides are slidably mounted on the top of the drying and curing structure, with both ends of the centering screw spirally passing through the two centering slides. One end of each of the two centering adjustment modules is fixedly connected to the sidewall of the two centering slides, and the other end of each centering adjustment module extends to the front end of the roller conveyor component, used to move the glass substrate from the side towards the centerline and to act on the defoaming component at the center position to adjust the width of the applied ultrasonic vibration.

[0014] In one alternative embodiment: the centering adjustment module includes a main boom frame, adjusting rollers, and a centering actuation unit. The main boom frame is arranged along the edge of the base portion, with one end fixedly connected to the side wall of the centering slide and the other end connected to the centering actuation unit. A plurality of adjusting rollers are arranged in the middle of the main boom frame, and the adjusting rollers correspond to each of the bubble removal components. The bottom of the adjusting rollers makes rolling contact with the upper surface of the electric base. The lower end of the centering actuation unit extends into the gap of the roller feeder component.

[0015] In one alternative embodiment: the centering actuation unit includes a centering auxiliary arm and multiple centering push rollers. The centering auxiliary arm is fixed to the end of the main arm frame away from the centering drive unit. The multiple centering push rollers are equidistantly and rotatably mounted on the centering auxiliary arm, with their lower ends extending into the gap of the roller conveyor component. Each centering push roller has a pressure sensing layer on its surface, which generates a sensing signal when it contacts the side of the glass substrate to control the centering drive unit to stop working.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects: This invention utilizes multiple defoaming components distributed along the conveying direction and ultrasonic vibration applied to the coated fire-retardant adhesive to rapidly expand, rise, and burst air bubbles within the adhesive, achieving an active, rapid, and uniform defoaming effect. Compared to traditional static defoaming or mechanical rolling methods, this invention effectively eliminates tiny residual air bubbles, avoids voids and surface defects within the adhesive layer, and thus significantly improves the light transmittance, flatness, and thermal insulation integrity of fire-retardant glass at high temperatures. This invention utilizes a centering monitoring component where two sections move synchronously along the width direction. This actively corrects any misalignment of the glass substrate, ensuring it remains aligned with the transport centerline. Furthermore, during the correction process, it coordinates and adjusts the width of the ultrasonic vibration of each defoaming component to precisely match the actual width of the glass. This design avoids the application of ultrasonic energy to blank areas or glass edges, eliminating the risk of damage to the glass edges from excessive vibration (such as adhesive wrinkling or stress cracking) and ensuring uniform defoaming effect across the entire width. It is particularly suitable for flexible production of multi-specification glass. In this invention, the coating, active defoaming, adaptive centering, and gradient curing processes are compactly integrated on the same roller conveyor component along the conveying direction, realizing automated continuous forming of fireproof glass substrates, reducing inter-process transfer and waiting time, and significantly improving production cycle while ensuring processing quality, making it suitable for large-scale industrial production.

Detailed Implementation

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0028] In one embodiment, such as Figure 1 and Figure 2As shown, a continuous fire-resistant molding device for architectural glass includes a base 100, a side control body 200, and a centering monitoring component. The upper surface of the base 100 is provided with a roller conveyor component 300 for carrying and conveying a glass substrate 400. Along the direction of conveying the glass substrate 400 via the roller conveyor component 300, a coating component 500, a defoaming component 600, and a drying and curing structure 700 are sequentially arranged. One end of the coating component 500 is connected to the side control body 200 and is used to coat the upper surface of the glass substrate 400 with fire-resistant adhesive. The drying and curing structure 700 is located at the downstream end of the roller conveyor component 300 and is used to heat and cure the glass substrate 400 coated with the fire-resistant adhesive to form a fire-resistant glass substrate. Multiple defoaming components 600 are included. One end is connected to the side control body 200. Multiple defoaming components 600 are distributed between the coating component 500 and the drying and curing structure 700 along the conveying direction of the glass substrate 400. Their working surfaces face the upper surface of the glass substrate 400 and are used to apply ultrasonic vibration to the fireproof adhesive to cause bubbles to rise and break. The centering monitoring component is set above the defoaming component 600. It has two branches and extends along the conveying direction of the glass substrate 400 to the front end of the roller conveyor component 300. The two branches can move along the width direction of the roller conveyor component 300 to ensure that the glass substrate 400 is in the centerline position by moving it laterally. The middle of the two branches is connected to each defoaming component 600 and is used to adjust the width of the ultrasonic vibration applied by the defoaming component 600.

[0029] In this embodiment of the invention, the glass substrate 400 to be processed is placed on the upper surface of the roller conveyor component 300. The centering monitoring component operates, with its two branches moving from both sides of the roller conveyor component 300 towards its centerline. The branches contact the sides of the glass substrate 400 and push it towards the centerline. Simultaneously, the branches act on each defoaming component 600, which automatically adjusts the width of the ultrasonic vibration to accommodate the width of the glass substrate 400. This avoids uneven defoaming in the fire-retardant adhesive and unnecessary ultrasonic action, and also prevents wrinkles from forming on the edges of the glass substrate 400 due to vibration. The glass substrate 400 remains at the centerline position throughout its movement on the upper surface of the roller conveyor component 300. The arrangement ensures that the glass substrate 400 is precisely moved to the working positions of the coating component 500, the defoaming component 600, and the drying and curing structure 700. When the glass substrate 400 passes through the coating component 500, the defoaming component 600, and the drying and curing structure 700, the coating component 500 coats the upper surface of the glass substrate 400 with fire-retardant adhesive, and the defoaming component 600 applies ultrasonic waves to the fire-retardant adhesive on the surface of the glass substrate 400, causing it to vibrate, thereby causing the bubbles to expand rapidly and rise to the liquid surface and burst, thus achieving active defoaming. The drying and curing structure 700 adopts a tunnel-type dryer, and the glass substrate 400 is dried inside the drying and curing structure 700 to achieve the setting of the fire-retardant adhesive. Its internal temperature decreases in a stepwise manner along the conveying direction of the glass substrate 400.

[0030] The base portion 100 is hollow inside and has a liquid receiving tray below the coating assembly 500 to receive excess fire retardant adhesive.

[0031] In one embodiment, such as Figures 1-4As shown, the defoaming assembly 600 includes a defoaming transverse frame 610, a power supply 630, and ultrasonic transducers 650. The defoaming transverse frame 610 is transversely arranged above the roller conveyor component 300, and one end of it is connected to the roller conveyor component 300 via an extension connecting arm 640. Multiple ultrasonic transducers 650 are evenly distributed along the width of the roller conveyor component 300 on the end face of the defoaming transverse frame 610 facing the glass substrate 400. Each ultrasonic transducer 650 has an electric holder 620 on its non-working end face, and a power supply is provided on the extension connecting arm 640. The power source 630 and the power supply 630 are connected to each of the arranged electrical bases 620 through a parallel circuit. In this embodiment of the invention, the connection between each arranged electrical base 620 adopts a parallel circuit. The surface of the arranged electrical base 620 has circuit contacts. When the centering monitoring component passes through the surface of the arranged electrical base 620, it contacts the circuit contacts to switch the working state of the ultrasonic vibrating plate 650, thereby adjusting the ultrasonic vibration range of the entire defoaming assembly 600. The working principle of the ultrasonic vibrating plate 650 is: high-frequency mechanical vibration is transmitted to the liquid fireproof adhesive layer through air or contact medium, forming an alternating sound pressure field inside the adhesive layer. Under the action of the sound pressure field, the microbubble nuclei in the adhesive liquid undergo periodic expansion and compression. When the sound pressure is sufficient, the bubbles rapidly expand and float to the liquid surface and burst, thereby achieving active defoaming. Compared with natural static defoaming, ultrasonic vibration can reduce the bubble content in the adhesive layer to an acceptable level in a shorter time, especially for high-viscosity fireproof adhesive liquids.

[0032] In one embodiment, such as Figures 1-4 As shown, the ultrasonic frequencies of the multiple bubble removal components 600 are distributed in a gradient decreasing manner along the conveying direction of the glass substrate 400, and the ultrasonic frequency range of the bubble removal components 600 is 20kHz-80kHz. In this embodiment of the invention, the technical significance of adopting a gradient frequency arrangement is that when the glass substrate 400 enters the bubble removal area from the coating station, the bubble size distribution inside the adhesive layer is relatively wide. High-frequency ultrasound has a better resonance removal effect on small-sized bubbles. As the transmission progresses, larger-sized bubbles have been basically eliminated, and the remaining small bubbles can continue to act through lower frequencies, realizing a graded bubble removal strategy of "first removing small bubbles with high frequency, then consolidating with low frequency", which takes into account both bubble removal efficiency and energy consumption economy.

[0033] In one embodiment, such as Figures 1-4As shown, a lifting assembly is provided on the side control body 200. The lifting assembly includes a lifting connecting frame 210 and at least one lifting cylinder 220. The lifting cylinder 220 is fixedly connected to the ends of multiple bubble removal components 600 and is vertically slidably connected to the outer wall of the side control body 200. The lifting cylinder 220 is mounted on the side control body 200, and its telescopic end is connected to the lifting connecting frame 210. In this embodiment of the invention, the lifting cylinder 220 is an electrically controlled cylinder that drives the lifting connecting frame 210 to move vertically. The multiple bubble removal components 600 follow the vertical movement of the lifting connecting frame 210 to adjust the distance between the ultrasonic transducer plate 650 and the glass substrate 400. The distance adjustment can adapt to the process requirements of glass substrates 400 with different thicknesses and different coating thicknesses, and can also optimize the energy coupling efficiency along the ultrasonic wave propagation path. Experimental verification shows that a distance of 5mm-30mm between the ultrasonic transducer plate 650 and the upper surface of the glass substrate 400 has a better bubble removal effect.

[0034] In one embodiment, such as Figures 1-6 As shown, the coating assembly 500 includes a coating housing 510, a main pipeline 520, and a liquid injection assembly. The coating housing 510 is arranged along the width direction of the roller conveyor component 300, and one end of it is connected to the side control body 200 through an external connector 580. The main pipeline 520 is located inside the coating housing 510, and multiple control valves 540 are evenly distributed on it. The multiple control valves 540 divide the main pipeline 520 into multiple adhesive pipelines, and each adhesive pipeline is provided with a coating head 530 facing the glass substrate 400. In this embodiment of the invention, the liquid injection assembly injects fire-retardant adhesive into the main pipeline 520 and distributes it to the multiple adhesive pipelines. The control valves 540 control the opening and closing of each adhesive pipeline, adapting to the width of the glass substrate 400 when coating the upper surface. The fire-retardant adhesive is evenly distributed on the upper surface of the glass substrate 400 in the form of a liquid film through the coating head 530.

[0035] The liquid injection assembly includes a liquid injection pipeline 550, a liquid storage tank 560, and a flow-controlled liquid injection pump 570. The liquid storage tank 560 is mounted on the side control body 200, and its outlet end is connected to the flow-controlled liquid injection pump 570. The flow-controlled liquid injection pump 570 is connected to the middle of the main pipeline 520 through the liquid injection pipeline 550 and is used to regulate the flow rate of the fireproof adhesive into the main pipeline 520.

[0036] In one embodiment, such as Figures 1-7As shown, the centering monitoring component includes a centering drive unit 800 and two centering adjustment modules 900. The centering drive unit 800 includes a centering screw 810, a centering motor 820, and two centering slides 830. The centering screw 810 is rotatably mounted on the top of the drying and curing structure 700, and its axis is aligned with the width direction of the roller conveyor component 300. The centering screw 810 is a left- or right-handed screw, and its end is connected to the output end of the centering motor 820. The two centering slides 830 are slidably mounted on the top of the drying and curing structure 700, and both ends of the centering screw 810 spirally pass through the two centering slides 830 respectively. One end of each of the two centering adjustment modules 900 is connected to the side wall of the two centering slides 830 respectively. A fixed connection is established, with the other end of the centering adjustment module 900 extending to the front end of the roller conveyor component 300. This module is used to move the glass substrate 400 from the side towards the centerline and to act on the bubble removal component 600 at the center position to adjust the width of the applied ultrasonic vibration. In this embodiment, the centering motor 820 drives the centering screw 810 to rotate. The centering screw 810, through a helical engagement with two centering slides 830, drives the two centering adjustment modules 900 to move towards or away from each other. The two centering adjustment modules 900 move from both sides of the roller conveyor component 300 towards the centerline, thereby moving the glass substrate 400 to the center position of the roller conveyor component 300, ensuring that the glass substrate 400 accurately reaches the subsequent processing position.

[0037] In one embodiment, such as Figures 1-7 As shown, the centering adjustment module 900 includes a main boom frame 910, adjusting roller pressing parts 920, and a centering actuation unit. The main boom frame 910 is arranged along the edge of the base portion 100, with one end fixedly connected to the side wall of the centering slide 830 and the other end connected to the centering actuation unit. Multiple adjusting roller pressing parts 920 are arranged in the middle of the main boom frame 910, and the adjusting roller pressing parts 920 correspond to each bubble removal component 600. The bottom of the adjusting roller pressing parts 920 rolls in contact with the upper surface of the arrangement electric seat 620. The lower end of the centering actuation unit extends into the gap of the roller feeder component 300. In this embodiment of the invention, the main boom frame 910 moves along the width direction of the roller feeder component 300 following the centering slide 830. The adjusting roller pressing parts 920 move along the main boom frame 910 and touch the circuit contacts when passing the arrangement electric seat 620. The circuit contacts switch the on / off state of the parallel circuit, thereby switching the working state of the ultrasonic vibrating plate 650.

[0038] In one embodiment, such as Figures 1-7As shown, the centering actuation unit includes a centering auxiliary arm 930 and multiple centering push rollers 940. The centering auxiliary arm 930 is fixed to the end of the main arm frame 910 away from the centering drive unit 800. The multiple centering push rollers 940 are equidistantly and rotatably mounted on the centering auxiliary arm 930, with their lower ends extending into the gap of the roller conveyor component 300. Each centering push roller 940 has a pressure-sensing layer on its surface. In this embodiment of the invention, the centering push rollers 940 follow the centering auxiliary arm. 930 and the main boom 910 move along the width direction of the roller conveyor component 300. When they come into contact with the side of the glass substrate 400, the pressure sensing layer senses a signal. When the pressure sensing layers in both centering actuation units generate sensing signals, the centering drive unit 800 stops working. At this time, the glass substrate 400 is in the centerline position. The centering push roller 940 rotates with the side of the glass substrate 400 without hindering the movement of the glass substrate 400 on the roller conveyor component 300.

[0039] The above embodiments provide a continuous fire-resistant forming device for architectural glass, the working principle of which is as follows: The glass substrate 400 to be processed is placed on the upper end face of the roller conveyor component 300 and passes through the coating component 500, the defoaming component 600 and the drying and curing structure 700 in sequence along the conveying direction.

[0040] Before or at the initial stage of conveying, the centering monitoring component is activated. The centering motor 820 in its centering drive unit 800 drives the centering screw 810 to rotate. This screw is a left- or right-handed screw, causing two centering slides 830 to move towards each other along the width of the roller conveyor component 300. The two centering slides 830 respectively drive the centering adjustment module 900 fixed to them to move. Specifically, the main arm frame 910 drives the centering auxiliary arm 930 at its end and multiple centering push rollers 940 rotatably mounted on it to move from both sides towards the centerline. When the centering push rollers 940 contact the side of the glass substrate 400, the pressure sensing layer on its surface generates a sensing signal. After both sides are triggered, the centering drive unit 800 stops operating. At this time, the glass substrate 400 is pushed to the center position of the roller conveyor component 300, and the centering push rollers 940 maintain rotational contact with the side, without affecting subsequent conveying.

[0041] During the aforementioned alignment process, multiple adjusting rollers 920 located in the middle of the main boom frame 910 move with it and respectively roll into contact with the upper surface of the electric mounting base 620 on the corresponding bubble removal assembly 600. The surface of the electric mounting base 620 is provided with circuit contacts. When the adjusting rollers 920 pass by, an electrical switch is triggered, thereby switching on and off the parallel circuits corresponding to each ultrasonic transducer 650. This causes the ultrasonic transducers 650 located outside the width range of the glass substrate 400 to stop working, leaving only the ultrasonic transducers 650 matching the width of the adhesive layer in the working state, thus achieving adaptive adjustment of the ultrasonic vibration width.

[0042] Subsequently, the glass substrate 400 continues to move forward on the roller conveyor assembly 300 while maintaining its centerline position, first reaching below the coating assembly 500. The liquid storage tank 560 on the side control unit 200 stores the fire-retardant adhesive. After the flow rate is regulated by the flow-controlled injection pump 570, the adhesive is delivered through the injection pipeline 550 to the main pipeline 520 inside the coating housing 510. Multiple control valves 540 are evenly spaced along the main pipeline 520. The corresponding number of valve sections are opened according to the actual width of the glass substrate 400, allowing the adhesive to flow evenly onto the upper surface of the glass substrate 400 in the form of a liquid film through each coating head 530. Excess fire-retardant adhesive falls into a receiving tray located below the coating assembly 500 inside the base portion 100 for recycling.

[0043] After coating, the glass substrate 400 enters the defoaming area composed of multiple defoaming components 600. Each defoaming component 600 spans above the roller conveyor component 300 via a defoaming transverse frame 610, with one end connected to the roller conveyor component 300 via an extension connecting arm 640. A power supply 630 is mounted on the arm, supplying power to each arranged base 620 through a parallel circuit, thereby driving the ultrasonic vibrating plate 650 to operate. The ultrasonic vibrating plate 650 generates high-frequency mechanical vibration, which is transmitted to the fireproof adhesive layer through air or contact medium, forming an alternating sound pressure field inside the adhesive layer. This causes the bubble nuclei in the adhesive to periodically expand and compress, eventually rising to the liquid surface and rupturing, thus achieving active defoaming.

[0044] The ultrasonic frequencies of multiple degassing components 600 decrease in a gradient along the conveying direction of the glass substrate 400, with a frequency range of 20kHz to 80kHz. A higher frequency is used in the initial stage to remove a large number of tiny air bubbles present in the adhesive layer during the initial coating process; a lower frequency is used in the later stage to thoroughly remove the remaining air bubbles, thereby achieving a graded degassing strategy.

[0045] In addition, the side control unit 200 is equipped with a lifting assembly, including a lifting connecting frame 210 and a lifting cylinder 220. The lifting cylinder 220 drives the lifting connecting frame 210 to move vertically, thereby driving the multiple de-bubbling components 600 to rise and fall as a whole, so as to adjust the distance between the ultrasonic transducer plate 650 and the upper surface of the glass substrate 400. This distance can be adaptively adjusted according to different thicknesses of glass substrates and coating thicknesses to optimize ultrasonic energy coupling efficiency and ensure de-bubbling effect.

[0046] Finally, the glass substrate 400 enters the drying and curing structure 700 located at the downstream end of the roller conveyor component 300. This structure uses a tunnel-type dryer, whose internal temperature decreases in a stepped manner along the conveying direction of the glass substrate 400. The glass substrate 400 coated with fire-retardant adhesive is heated and cured to set the fire-retardant adhesive, ultimately forming the finished fire-retardant glass substrate.

[0047] In summary, this device achieves automatic centering of the glass substrate and synchronous adjustment of the ultrasonic vibration width through the centering monitoring component. Combined with gradient frequency debubbling and controllable coating, it completes a continuous molding process from coating, debubbling to drying and curing.
