Abstract
Description
Technical Field

[0002] Currently, in the field of flexible display device manufacturing, ultra-thin flexible glass has become a key cover material for high-end products such as foldable screens due to its excellent flexibility and optical properties. However, due to its extremely thin thickness, it is prone to edge breakage or overall warping during single-unit processing, and traditional manual operations can no longer meet its precision processing requirements.
[0003] When encapsulating and protecting ultra-thin glass attached to carrier tape, the processes of dispensing adhesive, laminating film, and rolling are typically required. Currently, this process largely relies on manual operation: operators must first dispense adhesive into the gaps and on the surface of the glass, then manually cover it with a protective film, and finally roll it to remove air bubbles and ensure a uniform adhesive layer. Manual operation makes it difficult to guarantee the accuracy of the dispensing path and amount of adhesive, easily causing adhesive overflow or uneven coverage; secondly, manual lamination is prone to wrinkles and air bubbles, and the rolling pressure is difficult to control evenly, directly affecting the encapsulation quality and product reliability; at the same time, manual operation is inefficient and cannot adapt to the pace of large-scale, continuous production.

[0021] like Figures 1 to 9 As shown, the dispensing and coating roller pressing device of the present invention includes a carrying mechanism, a pretreatment mechanism 20, a dispensing mechanism 30, and a coating roller pressing mechanism 40. Figure 10 As shown, this is the material to be processed by the above-mentioned dispensing and coating roller pressing device. The material includes a carrier belt 100 and ultra-thin glass 200 spaced apart on the carrier belt 100. The dispensing mechanism 30 dispenses adhesive into the gaps and surfaces of the ultra-thin glass 200, forming an adhesive layer 300. The coating roller pressing mechanism 40 applies the coating 400 to the surface of the dispensed material, ultimately forming a film as shown. Figure 11 The finished product shown.
[0022] Please see Figures 1 to 9 The supporting mechanism provides highly stable positioning and support planes for each processing station. The supporting mechanism includes a feeding support platform 11, a dispensing vacuum adsorption platform 12, a roller pressing vacuum adsorption platform 13, and a discharging support platform 14, arranged sequentially along the material conveying direction. The material (i.e., the carrier belt 100 and the ultra-thin glass 200 on it) enters from the feeding support platform 11, undergoes dispensing at the dispensing vacuum adsorption platform 12, is then rolled by the roller pressing vacuum adsorption platform 13 to complete the film coating 400 process, and finally exits from the discharging support platform 14. Preferably, both the dispensing vacuum adsorption platform 12 and the roller pressing vacuum adsorption platform 13 include a marble base and a microporous ceramic platform embedded in the top of the marble base. The marble base ensures extremely high flatness and thermal stability, while the microporous ceramic platform generates uniform vacuum adsorption force, enabling stable adsorption and flattening of the carrier belt 100, providing a crucial positioning reference for subsequent precision operations.
[0023] Please see Figure 5The pretreatment mechanism 20 is mounted on the feeding support platform 11 and is used to pretreat the material to ensure the quality of subsequent processing. The pretreatment mechanism 20 includes a limiting edge pressing assembly 21 and a first static elimination module 22. The limiting edge pressing assembly 21 specifically includes a rotating shaft 211 mounted on the feeding support platform 11, two adjusting cylinders 212 respectively mounted at both ends of the rotating shaft 211 and drivenly connected to the rotating shaft 211, and two cylindrical limiting pressing blocks 213 symmetrically fixed on the rotating shaft 211; the position of the limiting pressing blocks 213 precisely corresponds to the two side edge areas of the material (carrier belt 100) in the width direction. When the material is conveyed to the feeding support platform 11, the adjusting cylinders 212 drive the rotating shaft 211 to descend, causing the two limiting pressing blocks 213 to press down synchronously until the pressing blocks contact the edge of the material and apply appropriate pressure, effectively restraining the warping of the flexible carrier belt 100 on both sides due to tension release or inertia during the conveying process, so as to keep the carrier belt 100 flat. The first static elimination module 22 is located downstream of the limiting and pressing assembly 21 and is used to generate ion wind to neutralize the static electricity on the material surface.
[0024] Please see Figure 6 The dispensing mechanism 30 is located above the dispensing vacuum adsorption stage 12. The dispensing mechanism 30 includes a gantry frame 31 spanning the dispensing vacuum adsorption stage 12, a lifting drive assembly 32 mounted on the gantry frame 31, a dispensing assembly 33 driven and connected to the lifting drive assembly 32, and a glue supply system (not shown in the figure) connected to the dispensing assembly 33. A product sensor 35 (such as a high-precision vision sensor or laser displacement sensor) is fixedly mounted on one side of the gantry frame 31. The lifting drive assembly 32 includes a lifting motor 321 fixed to the top of the gantry frame 31 and a lifting seat 322 located on one side of the gantry frame 31 and driven by the lifting motor 321. The lifting motor 321 is specifically a stepper motor with a brake, which drives the dispensing assembly 33 to a lifting stroke of 100mm. The dispensing assembly 33 includes a mounting plate 331 mounted on the lifting seat 322 and multiple dispensing heads 332 arranged in parallel on the mounting plate 331 to achieve efficient synchronous multi-point dispensing operations. In this embodiment, 16 dispensing heads 332 are provided to ensure coverage of the dispensing adsorption stage. The number and spacing of the dispensing heads 332 can be adjusted according to specific process requirements.
[0025] During operation, the material adsorbed and fixed on the dispensing vacuum adsorption stage 12 is detected by the product sensor 35, which captures the position and height of the ultra-thin glass 200 on the carrier belt 100 to obtain position and height information. This position and height information is transmitted to the lifting drive assembly 32 to control the lifting height of the dispensing assembly 33, ensuring the distance between the dispensing head 332 and the surface of the ultra-thin glass 200. Simultaneously, the position and height information is transmitted to the glue supply system, which adaptively adjusts the glue supply amount and speed. Under program control, the dispensing assembly 33, based on the acquired position and height information, drives multiple dispensing heads 332 to precisely and quantitatively coat the material across the gaps and surface of the ultra-thin glass 200, thereby forming a uniform glue layer 300.
[0026] Please see Figures 7 to 9 The laminating roller pressing mechanism 40 is used to complete the supply, processing, and pressing operations of the protective film. The laminating roller pressing mechanism 40 includes a support frame 41, an unwinding assembly 42, a separating roller 43, a rewinding assembly 44, a primary roller pressing assembly 45, and a secondary roller pressing assembly 46. The support frame 41 is mounted on top of the discharge support platform 14, and the unwinding assembly 42, the separating roller 43, and the rewinding assembly 44 are all mounted on the support frame 41. The primary roller pressing assembly 45 and the secondary roller pressing assembly 46 are both mounted on the roller pressing vacuum adsorption platform 13. The unwinding assembly 42 is used to supply the composite film material including the protective film and the laminating film 400. The separating roller 43 is used to separate the protective film and the laminating film 400. The rewinding assembly 44 is used to collect the separated protective film. The separated laminating film 400 is guided to the area below the primary roller pressing assembly 45 and the secondary roller pressing assembly 46 for pressing.
[0027] Specifically, the unwinding assembly 42 is used to supply the film-coated 400 strip with a protective film. The unwinding assembly 42 includes an unwinding drive roller 421 and multiple parallel transition rollers 422 to form a stable unwinding path. To further improve process quality, a dust removal and cleaning module 47 and a second static elimination module 48 can also be provided between the transition rollers 422 and the separating roller 43. The dust removal and cleaning module 47 includes at least one conveying roller 471 and two dust removal rollers 472 respectively disposed on the upper and lower sides of the conveying roller 471. The surface of the dust removal rollers 472 is covered with dust removal tape (not shown in the figure) for removing minute contaminants from the surface of the film material.
[0028] The unwinding assembly 42 also includes a film cutting module 49 disposed between the unwinding drive roller 421 and the transition roller 422, for realizing roll changing without stopping the machine during production. The film cutting module 49 includes a first linear guide rail 491, a first drive module 492, a mounting support 493, a second linear guide rail 494, a second drive module 495, a sliding seat 496, an upper vacuum suction plate 497, a lower vacuum suction plate 498, a cutting drive module 499, and a cutting blade 490. The first linear guide rail 491 is fixedly mounted on the support frame 41 along the material conveying direction, and the mounting bracket 493 is slidably connected to the first linear guide rail 491; the first drive module 492 is fixed on the support frame 41, and its output end is connected to the mounting bracket 493 for driving the mounting bracket 493 to move along the first linear guide rail 491; the second linear guide rail 494 is fixedly mounted on the bottom of the mounting bracket 493 perpendicular to the material conveying direction, and the sliding seat 496 is slidably connected to the second linear guide rail 494; the second drive module 495 is fixed on... The output end of the mounting bracket 493 is connected to the sliding seat 496 to drive the sliding seat 496 to move along the second linear guide rail 494. The upper vacuum suction plate 497 and the lower vacuum suction plate 498 are fixed on the sliding seat 496, forming a cutting gap between them. The cutting drive module 499 is fixed on the sliding seat 496. The cutting blade 490 is connected to the output end of the cutting drive module 499. The cutting drive module 499 is a linear drive module that drives the cutting blade 490 to move along the cutting gap. When roll changing and cutting are required, the first drive module 492 and the second drive module 495 are used to move the film cutting module 49 in two mutually perpendicular directions in the horizontal plane. At the same time, the upper vacuum suction plate 497 and the lower vacuum suction plate 498 simultaneously hold the film material, and the cutting drive module 499 drives the cutting blade 490 to cut the film material. To achieve efficient and continuous operation, the unwinding active roller 421 and the film cutting module 49 are set one-to-one, and each can be configured with two sets to form a dual-station unwinding system.
[0029] The primary roller pressing assembly 45 and the secondary roller pressing assembly 46 are used to sequentially roll-press the film 400 onto the surface of the adhesive-coated material. Both are communicatively connected to the product sensor 35 to receive position and height information. Each assembly includes two mounting brackets 461 oppositely positioned on either side of the roller pressing vacuum adsorption table 13, a lifting drive module 462 mounted on the brackets, a roller pressing bearing seat 463 driven by the lifting drive module 462 and movably connected to the brackets, and a pressure roller 464 supported at both ends between the bearing seats. The lifting drive module 462 drives the roller pressing bearing seat 463 and the pressure roller 464 to move up and down. During operation, both components dynamically adjust the pressing height and pressure based on the material height information provided by the product sensor 35. The primary roller pressing assembly 45 performs initial bonding and air venting, while the secondary roller pressing assembly 46 completes the final fine pressing and leveling, thereby ensuring that the film 400 is flat, bubble-free, and firmly adhered to the adhesive layer 300.
[0030] like Figure 12 As shown, the dispensing and coating 400 rolling method of the present invention, based on the above-described dispensing and coating rolling apparatus, includes the following steps: S1. Feeding and pretreatment: The carrier belt 100 carrying the ultra-thin glass 200 is conveyed to the feeding support table 11, the two sides of the carrier belt 100 are pressed by the limiting edge pressing component 21, and the surface static electricity is eliminated by the first static elimination module 22.
[0031] S2. Visual Guidance and Precision Dispensing: The material is conveyed to the dispensing vacuum adsorption stage 12 for adsorption and fixation. The position and height information of the ultra-thin glass 200 are sensed by the product sensor 35; the lifting drive component 32 of the dispensing mechanism 30 drives the dispensing component 33 to rise and fall to the optimal working height according to the received height information; at the same time, the glue supply system precisely controls the glue supply amount and dispensing speed of each dispensing head 332 according to the arrangement position and path planning of the glass. Subsequently, under the program control, the dispensing component 33 performs multi-point, quantitative dispensing of glue on the gaps between the ultra-thin glass 200 and on the glass surface according to the preset path, forming a uniform and continuous glue layer 300.
[0032] S3. Adaptive Pressure Rolling and Coating 400: The dispensing material is conveyed to the roller vacuum adsorption table 13 and adsorbed and fixed. The coating roller pressing mechanism 40 is activated, and the unwinding assembly 42 supplies the coated tape 400 with a protective film. After being cleaned by the dust removal and cleaning module 47 and the second static elimination module 48, the protective film is separated from the coating 400 by the separating roller 43. The protective film is recovered by the winding assembly 44, while the coating 400 is guided to be directly above the dispensing material. The primary roller pressing assembly 45 and the secondary roller pressing assembly 46 dynamically adjust their respective descent height and applied pressure according to the height position information obtained in step S2. The primary roller pressing assembly 45 first performs preliminary roller pressing with set parameters to achieve initial bonding of the film 400 and remove most of the air bubbles; then the secondary roller pressing assembly 46 performs final fine pressing with adjusted parameters to completely remove residual air bubbles and make the adhesive layer 300 flow evenly and level, ensuring that the film 400 and the adhesive layer 300 achieve complete bonding without air bubbles or wrinkles.
[0033] S4. Finished Product Output: The packaged material is conveyed to the discharge support platform 14 to complete the entire automated processing flow.
[0034] Compared to existing technologies, the dispensing and coating roller pressing device and method of this invention includes a carrying mechanism, a pretreatment mechanism 20, a dispensing mechanism 30, and a coating roller pressing mechanism 40. The carrying mechanism provides a continuous conveying and positioning foundation for materials through a feeding support platform 11, a dispensing vacuum adsorption platform 12, a roller pressing vacuum adsorption platform 13, and a discharging support platform 14 arranged in sequence. The pretreatment mechanism 20 is located on the feeding support platform 11, and its limiting edge pressing component 21 presses the material edge, while the first electrostatic elimination module 22 eliminates static electricity on the material surface, effectively ensuring the flatness and cleanliness of the material before entering the processing area. The dispensing mechanism 30 includes... The system includes a gantry frame 31 spanning across the entire structure, a lifting drive assembly 32, a dispensing assembly 33, and a glue supply system. A product sensor 35 located on one side of the gantry frame 31 precisely senses the position and height of the ultra-thin glass 200. This information is simultaneously transmitted to the lifting drive assembly 32 to adjust the dispensing height and to the glue supply system to control the glue supply quantity and speed, thereby achieving precise and quantitative application of the glue in the glass gaps and on the surface. The laminating roller pressing mechanism 40, through its support frame 41, unwinding assembly 42, separating roller 43, rewinding assembly 44, primary pressing assembly 45, and secondary pressing assembly 46, works collaboratively to complete the supply and pressing operation of the laminating film 400. The unwinding assembly 42 continuously supplies the laminating film 400 with a protective film. After being separated by the separating roller 43, the protective film is recovered by the rewinding assembly 44, and the laminating film 400 is guided to the pressing station. Both the primary roll forming assembly 45 and the secondary roll forming assembly 46 are communicatively connected to the product sensor 35. Based on the received glass height information, they can sequentially roll and adhere the film 400 to the surface of the glued material with different pressures and heights, achieving a bubble-free and smooth film 400 effect. The product sensor 35, as the core sensing unit, simultaneously provides the same set of position and height information acquired by it to the dispensing mechanism 30 and the film rolling mechanism 40, enabling the dispensing positioning, glue supply control, and roll forming parameter settings to form a closed-loop adaptive adjustment.
[0035] The above description merely illustrates preferred technical solutions of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the invention patent. 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.
