They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] like Figures 1 to 13 As shown, the ultra-thin glass coating and curing production line of the present invention includes an unwinding device 10, a cleaning device 20, a UV light cleaning device 30, a first speed detection and compensation device 40, a glue dispensing roller pressing device 50, a curing device 60, a second speed detection and compensation device 70, a thickness measuring device 80, an optical detection device 90, and an edge trimming and winding device 100 arranged sequentially along the material conveying direction.

[0022] Please see Figure 2 The unwinding device 10 is used to output the flexible carrier tape carrying ultra-thin glass. The unwinding device 10 is equipped with an unwinding drive roller 11, an unwinding receiving platform 12, and a protective film tearing module. The unwinding drive roller 11 provides active traction power for material conveying, ensuring smooth output of the carrier tape. The unwinding receiving platform 12 is located downstream of the unwinding drive roller 11 and assists in connecting new and old rolls, enabling roll changing without stopping the machine. The protective film tearing module is located downstream of the unwinding receiving platform 12 and automatically peels off and winds up the protective film covering the carrier tape before it enters subsequent processes, ensuring that the clean surface of the ultra-thin glass directly enters the cleaning process. The protective film tearing module also has an ionizing function to eliminate static electricity on the surface.

[0023] Please see Figure 2The cleaning device 20 is used to clean the flexible carrier belt and ultra-thin glass to remove impurities and static electricity. The cleaning device 20 includes a first air-cutting unit 21, a detergent spraying unit 22, a second air-cutting unit 23, a first pure water spraying unit 24, a second pure water spraying unit 25, a third pure water spraying unit 26, a deionized water spraying unit 27, a first air knife drying unit 28, and a second air knife drying unit 29 arranged sequentially along the material conveying direction. The first air-cutting unit 21 is used to blow away large particulate impurities attached to the surface of the material; the detergent spraying unit 22 sprays cleaning liquid to dissolve contaminants such as grease; the second air-cutting unit 23 further blows away residual droplets and impurities; subsequently, the first pure water spraying unit 24, the second pure water spraying unit 25 and the third pure water spraying unit 26 sequentially perform multi-stage progressive rinsing on the material to gradually remove cleaning agent residue; the deionized water spraying unit 27 provides a final high-cleanliness rinsing to further reduce ion contamination; finally, the first air knife drying unit 28 and the second air knife drying unit 29 use high-speed airflow to thoroughly dry the surface moisture of the material, ensuring that the material enters the subsequent process in a dry and clean state.

[0024] Please see Figure 2 The UV light cleaning device 30 is used to perform UV light cleaning on flexible carrier belts and ultra-thin glass to remove organic residues and activate the surface. The device uses a light irradiation chamber with an automatic baffle. When the material is conveyed to the preset position and pauses temporarily, the automatic baffle closes to isolate external light and prevent ultraviolet leakage, ensuring a stable and safe UV light irradiation process. After cleaning, the baffle automatically opens, and the material continues to be conveyed.

[0025] Please see Figures 3 to 5 The first speed detection and compensation device 40 is used to detect and compensate for the speed difference between its upstream and downstream equipment. The first speed detection and compensation device 40 includes a cabinet 41, which has an inlet end and an outlet end. A detection area 41a is located between the inlet end and the outlet end within the cabinet 41. The inlet end has an inlet roller 42, and the outlet end has an outlet roller 43. Both the inlet roller 42 and the outlet roller 43 are vacuum adsorption rollers with negative pressure adsorption holes on their surfaces. The inlet roller 42 is an active roller, and its interior has an air passage communicating with the negative pressure adsorption holes. A negative pressure is established through an external vacuum system to stably adsorb the material. A high-position photoelectric sensor 44 and a low-position photoelectric sensor 45 are fixedly installed within the detection area 41a, and the high-position photoelectric sensor 44 and the low-position photoelectric sensor 45 are spaced apart vertically. The material sequentially passes through the inlet roller 42, the detection area 41a, and the outlet roller 43, forming a free-hanging section within the detection area 41a.

[0026] When the upstream and downstream equipment conveys at synchronized speeds, the height of the free overhang section remains at a preset equilibrium position, without triggering the high-position photoelectric sensor 44 or the low-position photoelectric sensor 45. If the upstream equipment speed is relatively too slow, or the downstream equipment speed is relatively too fast, the material is tightened, causing the overhang section to rise. When the lowest point of the overhang section rises to trigger the high-position photoelectric sensor 44, the system determines that the upstream equipment speed is too slow and generates an acceleration signal. Conversely, if the upstream equipment speed is relatively too fast, the overhang section descends and triggers the low-position photoelectric sensor 45, and the system determines that the upstream equipment speed is too fast and generates a deceleration signal. The system adjusts the rotational speed of the drive roller in the upstream or downstream equipment in real time based on the above signals to achieve closed-loop compensation for the speed difference, thereby maintaining the stability of tension during material conveying.

Two symmetrically arranged cylindrical limiting blocks 553 are fixed on the rotating shaft 551, and the limiting blocks 553 are corresponding to the two side edges in the width direction of the material. The adjusting cylinders 552 drive the rotating shaft 551 to move vertically up and down, so as to move the limiting blocks 553 closer to the feeding support platform 51 and press the two side edges of the material to restrain its warping. The first static elimination module eliminates static electricity on the surface of the material after limiting and pressing the edge.

The cutting drive module 5789 is fixed on the sliding seat 5786, and the cutting blade 5780 is connected to the output end of the cutting drive module 5789. The cutting drive module 5789 drives the cutting blade 5780 to move along the cutting gap, achieving precise positioning and cutting of the film material. During roll changing, the film material cutting module 578 drives the sliding seat 5786 to move through the first drive module 5782 and the second drive module 5785, so that the upper and lower vacuum suction plates 5788 are positioned and adsorb the old film material. The cutting drive module 5789 drives the cutting blade 5780 to cut the old film material, thereby completing the introduction and splicing of the new roll of film material and realizing continuous feeding.

[0040] Please see Figure 3 The edge trimming and winding device 100 is used to trim the edges of the product and complete the winding of the finished product. Along the material conveying direction, the edge trimming and winding device 100 includes, in sequence, an edge trimming mechanism 110, an ion air blowing device 120, a winding receiving platform 130, a winding correction mechanism 140, and a winding drive roller 150. The edge trimming mechanism 110 is located on both sides of the material path and uses a circular knife or laser cutting method to simultaneously and precisely cut off the excess edges on both sides of the material according to the preset product width specifications, ensuring a consistent finished product width. The ion air blowing device 120 is located downstream of the edge trimming mechanism 110 and is used to blow ion air onto the material surface to eliminate surface static electricity and prevent interlayer adhesion or dust adsorption due to static electricity during subsequent winding. The winding receiving platform 130 is located in front of the winding station and is used to receive the empty roll core during roll changing, and assists in the switching of new and old roll materials and the fixing of the starting end, achieving continuous winding without stopping the machine. The winding correction mechanism 140 is located after the winding receiving platform 130 and typically includes a correction sensor and an actuator. It is used to detect the edge position of the material in real time and ensure that the material is always axially aligned during the winding process through lateral fine-tuning drive, thus avoiding uneven winding. The winding drive roller 150 is an active drive roller that, together with the tension control system, tightly and neatly winds the finished material, which has undergone edge trimming and static electricity elimination, into a roll.

[0041] like Figure 14 As shown, the ultrathin glass coating and curing method of the present invention, based on the above-mentioned ultrathin glass coating and curing production line, includes the following steps: S1. Unwinding: The unwinding device 10 outputs a flexible carrier belt carrying ultra-thin glass. The unwinding drive roller 11 provides continuous traction power, and the protective film on the surface of the material is automatically peeled off by the protective film peeling module before entering the cleaning device 20.

[0042] S2. Cleaning: The material from the unwinding device 10 is sequentially cleaned by the cleaning device 20 and then UV-cleaned by the UV light cleaning device 30. The material first passes through the first air-cutting unit 21, detergent spraying unit 22, second air-cutting unit 23, first pure water spraying unit 24, second pure water spraying unit 25, third pure water spraying unit 26, deionized water spraying unit 27, first air knife drying unit 28, and second air knife drying unit 29 of the cleaning device 20, completing multi-stage cleaning and drying. It then enters the UV light cleaning device 30, where it is irradiated with UV light under the protection of an automatic baffle, achieving surface activation and removal of organic residues. S3. First speed detection and compensation: The first speed detection and compensation device 40 detects and adjusts the conveying speed of the material before it enters the dispensing roller device 50; S4. Dispensing and Rolling: The dispensing and rolling device 50 dispenses adhesive into the gaps and surface of the ultra-thin glass, and then rolls the coating onto the dispensed surface. Specifically, this includes the following sub-steps: S41. Pre-treatment and positioning: After the material enters the dispensing roller pressing device 50, the edge is first pressed by the limiting edge pressing component in the pre-treatment mechanism 55, and the static electricity is eliminated by the first static elimination module; then it is conveyed to the dispensing vacuum adsorption table 52 for adsorption, fixation and flattening.

[0043] S42. Visual guidance dispensing: The product sensor 566 acquires the position and height information of the ultra-thin glass on the carrier in real time; the lifting drive component in the dispensing mechanism 56 automatically adjusts the height of the dispensing component according to the position and height information, and the glue supply system synchronously controls the glue dispensing amount and speed, and completes the dispensing operation in the gap and surface of the ultra-thin glass through multiple dispensing heads 565.

[0044] S43. Coating supply and separation: The unwinding assembly of the coating roller pressing mechanism 57 continuously outputs the coating with protective film through the coating unwinding active roller 572 and the transition roller 573; after being processed by the dust removal and cleaning module 579 and the second static elimination module 570, the protective film is separated from the coating by the separation roller 574, the protective film is recovered by the winding assembly 575, and the coating is guided to the top of the glued material.

[0045] S44. Adaptive Roller Pressing: The material is conveyed to the roller press vacuum adsorption table 53 and adsorbed and fixed; the primary roller press assembly 576 and the secondary roller press assembly 577 adjust the pressing height and pressure through their respective lifting drive modules 5762 according to the position and height information in step S42, and roll the film in sequence: the primary roller press assembly 576 realizes the initial bonding and air bubble removal, and the secondary roller press assembly 577 completes the final compaction and leveling, ensuring that the film is flat and air bubble-free and bonded to the adhesive layer surface.

[0046] S5. Curing: The material that has been dispensed with adhesive is cured by the curing device 60; S6. Second speed detection and compensation: The second speed detection and compensation device 70 is used to detect and adjust the conveying speed of the material before it enters the detection process; S7. Inspection and winding: The material is inspected for thickness by the thickness measuring device 80 and defective products are marked; then the appearance defects are inspected by the optical inspection device 90; finally, the edge trimming and winding of the finished product are completed by the edge trimming and winding device 100. The material is trimmed of excess edges by the edge trimming mechanism 110, static electricity is eliminated by the ion air blowing device 120, and after being aligned by the winding and correction mechanism 140, it is neatly wound into a finished roll by the winding drive roller 150.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
