Description

Technical Field

[0001] This utility model relates to the field of coating roll pressing technology, and in particular to a dispensing component and an automatic dispensing coating roll pressing device. Background Technology

[0002] With the rapid development of flexible display technology, center-curved glass (CFG), due to its unique central groove structure and excellent mechanical properties, has gradually become a key material for foldable screen terminal devices. CFG requires surface functionalization treatment (such as wear resistance and folding resistance) through a full-surface coating process, and after coating, a lamination and rolling process is needed to ensure the uniformity and stability of the film layer. However, in related technologies, air bubbles are easily generated during the CFG lamination and rolling process, leading to poor film uniformity. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In related technologies, when CFG is applied by dispensing, the adhesive has a high viscosity and poor fluidity at room temperature. This can easily lead to the adhesive failing to fill the groove area in the middle of the CFG during the rolling process, resulting in air bubbles and uneven film thickness.

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, embodiments of this utility model propose a dispensing assembly that can improve the uniformity of film coating.

[0007] The embodiments of this utility model also propose an automatic dispensing and coating roller pressing device suitable for mass production of central flexible glass.

[0008] The dispensing assembly of this utility model includes a heating section and a dispensing section. The heating medium in the heating section exchanges heat with the adhesive in the dispensing section. The heating section includes a heating tube and a heat insulation component. The dispensing section includes a dispensing tube, a pressure regulating valve, and a dispensing valve. The dispensing tube includes a heat exchange tube section and a dispensing tube section connected together. The heat exchange tube section and the heating tube are disposed within the heat insulation component. The heat exchange tube section is arranged adjacent to the heating tube. The heat exchange tube section is a metal tube. The pressure regulating valve and the dispensing valve are sequentially arranged along the adhesive flow direction on the dispensing tube section.

[0009] The dispensing assembly of this utility model heats the adhesive before dispensing to reduce its viscosity and improve its fluidity, thereby solving the problem of air bubbles easily generated during subsequent rolling and improving the uniformity of film coating.

[0010] In some embodiments, the heating element further includes a temperature sensor and a temperature controller. The temperature sensor is connected to the dispensing tube and is used to monitor the temperature of the adhesive in the dispensing tube. The temperature controller is connected to the temperature sensor and the heating tube, and the temperature controller adjusts the heating temperature of the heating tube based on the monitoring data fed back by the temperature sensor.

The dispensed material is moved to the second platform by the translation component, and the second platform is movable along the first direction, so that the coating component can coat the material on the second platform and roll it to a preset film thickness by the rolling component.

[0013] The automatic dispensing and coating roller pressing device of this utility model can perform conformal dispensing around the perimeter of glass with different shapes and sizes, and the dispensing path can be set arbitrarily.

Detailed Implementation

[0050] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0051] The dispensing assembly of this utility model according to an embodiment is described below with reference to the accompanying drawings.

[0052] like Figures 1 to 4 As shown, the dispensing assembly of this utility model embodiment includes a heating section 21 and a dispensing section 22. The heating medium in the heating section 21 heats the adhesive in the dispensing section 22. The dispensing section 22 dispenses the heated adhesive onto the material on the first platform 1 according to a preset path.

[0053] Understandably, a single glass substrate contains multiple CFG products. Due to the characteristics of CFG products, there are grooves in the middle of the products. If the adhesive fails to fill these grooves during the subsequent rolling process, air bubbles will form. Therefore, to solve the problem of air bubbles easily generated during the subsequent rolling process, the adhesive is heated before dispensing to reduce its viscosity and increase its fluidity, thereby improving the uniformity of the coating.

[0054] Optionally, such as Figure 3 and Figure 4 As shown, the heating part 21 includes a heating tube 211 and a heat insulation component 212, and the dispensing part 22 includes a dispensing tube 221, a pressure regulating valve 222 and a dispensing valve 223.

[0055] The dispensing tube 221 includes a connected heat exchange tube section and a dispensing tube section. The heat insulation component 212 can be a box structure. The heat exchange tube section and the heating tube 211 are located inside the heat insulation component 212, with the heat exchange tube section arranged adjacent to the heating tube 211. The heating process of the adhesive takes place within the heat insulation component 212, which serves to insulate the temperature and improve the safety of the device. The heating tube 211 can be an electric heating element. The heating tube 211 transfers heat to the heat exchange tube section, heating the adhesive within the heat exchange tube section to a set temperature and reducing the viscosity of the adhesive. The heat exchange tube section is a metal tube, such as a stainless steel tube, to facilitate assembly within the heat insulation component 212. A pressure regulating valve 222 and a dispensing valve 223 are sequentially arranged along the adhesive flow direction within the dispensing tube section. The dispensing valve 223 controls the opening and closing of the dispensing tube section, and the pressure regulating valve 222 controls the air pressure of the dispensing valve 223.

[0056] The dispensing tube 221 has two sections. Only the heat exchange tube section is shown in the figure. The dispensing tube section is not shown in the figure. The dispensing tube section is a flexible tube and is provided with a margin for the dispensing valve 223 to move.

[0057] Furthermore, such as Figure 3 and Figure 4As shown, the heating unit 21 also includes a temperature sensor 213 and a temperature controller 214. The temperature sensor 213 is connected to the dispensing tube 221 and is used to monitor the temperature of the adhesive on the dispensing tube 221. The temperature controller 214 is connected to both the temperature sensor 213 and the heating element 211. The temperature controller 214 adjusts the heating temperature of the heating element 211 based on the monitoring data fed back from the temperature sensor 213. The temperature controller 214 can be set to the desired temperature, has an over-temperature alarm function, and carries a PID control function for regulation and suppression.

[0058] Optionally, such as Figures 1 to 4 As shown, the dispensing assembly 2 includes a U-shaped frame 23, a dispensing slide rail 24, a telescopic component 25, and a mounting plate 26. The lower end of the U-shaped frame 23 is connected to the frame 10, and the opening of the U-shaped frame 23 is set downward so that the first platform 1 can pass through the U-shaped frame 23.

[0059] A dispensing slide rail 24 is mounted on the U-shaped frame 23 and extends in the left-right direction. A telescopic component 25 is mounted on the dispensing slide rail 24 and connected to the mounting plate 26. The telescopic component 25 can be a telescopic cylinder, driving the mounting plate 26 to move vertically. A heat insulation component 212 is connected to the mounting plate 26 via an L-shaped connecting plate 27. The heat insulation component 212 is located above the U-shaped frame 23, and the distance between the heat insulation component 212 and the U-shaped frame 23 is greater than the maximum extension range of the telescopic component 25 to prevent interference between the heat insulation component 212 and the U-shaped frame 23 when the telescopic component 25 drives the mounting plate 26 downwards. A dispensing valve 223 and a pressure regulating valve 222 are located on the front wall of the mounting plate 26, with the pressure regulating valve 222 located above the dispensing valve 223.

[0060] The dispensing valve 223 moves left and right via the dispensing slide rail 24, and moves up and down via the telescopic component 25, in conjunction with the forward and backward movement of the first platform 1, so that the device can adapt to dispensing work for different product shapes.

[0061] Optionally, such as Figure 3 and Figure 4 As shown, the dispensing assembly 2 also includes an imaging element 28, which is disposed on the mounting plate 26. The imaging element 28 can be a CCD camera. CCD is short for charge coupled device. A CCD camera is any digital camera with a charge coupled device image sensor. The imaging element 28 is used to photograph the material on the first platform 1 to determine the preset path for dispensing by the dispensing unit 22.

[0062] Specifically, the imaging component 28 photographs key marking points on the glass substrate to determine the relative position of the CFG product on the glass substrate. The system then performs conformal dispensing around the CFG product according to a pre-set dispensing path. Compared with dispensing CFG products onto the surface in related technologies, the dispensing method in this embodiment of the invention improves dispensing accuracy and reduces adhesive usage.

[0063] The automatic dispensing and coating roller pressing device of this utility model is described below with reference to the accompanying drawings.

[0064] like Figures 1 to 16 As shown, the automatic dispensing and coating roller pressing device of this utility model embodiment includes a first platform 1, a dispensing assembly 2, a translation assembly 3, a second platform 4, a coating assembly 5, a roller pressing assembly 6, and a frame 10. The frame 10 serves as the main support structure of the entire device, and the first platform 1, the dispensing assembly 2, the translation assembly 3, the second platform 4, the coating assembly 5, and the roller pressing assembly 6 are all mounted on the frame 10.

[0065] The first platform 1 is movable along a first direction. The first direction can be the length direction of the frame 10, for example... Figure 1 The front-to-back direction is shown in the diagram. The first platform 1 is used to place raw materials, such as glass substrates with CFG products, and the dispensing operation is performed on the first platform 1.

[0066] The dispensing assembly 2 is the dispensing assembly in the above embodiment. The dispensing portion 22 of the dispensing assembly 2 is movable along a second direction and a third direction, the second direction being orthogonal to the first direction, and the third direction being orthogonal to the second direction and the first direction.

[0067] The second direction can be the width direction of the rack 10, for example... Figure 1 The left and right directions are shown in the diagram. The third direction can be the height direction of the frame 10, for example... Figure 1 The vertical direction is shown. The dispensing unit 22 dispenses heated adhesive onto the material on the first platform 1 according to a preset path.

[0068] After dispensing is completed, the material is moved from the first platform 1 to the second platform 4 by the translation component 3. The second platform 4 is movable along the first direction. The second platform 4 passes through the coating component 5 and the rolling component 6 in sequence. The coating component 5 coats the material with a film (e.g., PET film), and the rolling component 6 rolls the material to a preset film thickness (the film thickness uniformity is controlled at about 10um).

[0069] Here's a simplified example illustrating the entire workflow of a glass substrate with CFG products. First, preparation begins by placing the coating liquid into a sealed pressure tank. A vacuum pump evacuates the tank to remove bubbles from the adhesive, preventing air bubbles from forming during dispensing. The glass substrate with the CFG product is then placed on the first platform 1, which precisely positions the glass substrate. The dispensing assembly 2 performs conformal dispensing according to a preset path. After dispensing, the translation assembly 3 transfers the glass substrate to the second platform 4. The laminating assembly 5 covers the glass substrate with a PET film, and the rolling assembly 6 rolls it according to a preset film thickness. (Example...) Figure 2 As shown, the final shape obtained after the glass substrate with CFG product completes the dispensing, coating and rolling process is a glass substrate 20 at the bottom, an adhesive layer 30 and CFG (40) in the middle, and a PET film 50 at the top.

[0070] The automatic dispensing and coating roller pressing device of this utility model can perform conformal dispensing around the perimeter of glass with different shapes and sizes, and the dispensing path can be set arbitrarily. Furthermore, the adhesive is heated before dispensing to reduce its viscosity.

[0071] In some embodiments, such as Figures 5 to 7 As shown, the rolling assembly 6 includes a first rolling portion 61 and a second rolling portion 62. The first rolling portion 61 and the second rolling portion 62 are arranged at intervals in the front-to-back direction. The first rolling portion 61 is adjacent to the coating assembly 5 relative to the second rolling portion 62, that is, the first rolling portion 61 is located in front of the second rolling portion 62. The first rolling portion 61 and the second rolling portion 62 extend in the left-to-right direction and are movable in the up-down direction. At least a portion of the first rolling portion 61 has a lower hardness than the second rolling portion 62.

[0072] The main function of the roll forming assembly 6 is to roll the glass substrate by rotating the roll forming part, and to precisely control the film thickness of the product (CFG, UTG, etc.) by adjusting the gap between the roll forming part and the glass substrate.

[0073] The roll forming assembly 6 has at least three modes, including a first mode, a second mode, and a third mode.

[0074] In the first mode, when the leading end of the material on the second platform 4 moves close to the first roller pressing section 61, the first roller pressing section 61 begins to descend. Once the leading end of the material is below the first roller pressing section 61, the first roller pressing section 61 presses against the leading end of the material. It is understood that the purpose of initially pressing the material with the softer first roller pressing section 61 is to avoid misalignment during coating caused by directly pressing the material with the harder second roller pressing section 62, thereby improving the effectiveness of coating. After the first roller pressing section 61 presses the material, the second platform continues to move below the second roller pressing section 62, and the second roller pressing section 62 descends to press the material until the trailing end of the material is close to the first roller pressing section 61. Then, the first roller pressing section 61 descends again, pressing against the trailing end of the material to facilitate subsequent film cutting.

[0075] It is important to note that, such as Figure 1 As shown, the second platform 4 moves in the front-to-back direction, and the beginning of the material refers to... Figure 1 The rear end shown refers to the tail end of the material. Figure 1 The front end is shown in the image.

[0076] In the second mode, either the first roller pressing section 61 or the second roller pressing section 62 presses the material of the second platform 4. It is understood that when the second platform 4 moves through the roller pressing assembly 6, only the first roller pressing section 61 is used to press the material of the second platform 4, or only the second roller pressing section 62 is used to press the material of the second platform 4.

[0077] In the third mode, the first roller pressing section 61 and the second roller pressing section 62 alternately press the material on the second platform 4. It can be understood that the material is first completely pressed once by the first roller pressing section 61, and then completely pressed again by the second roller pressing section 62, and this process can be repeated multiple times; alternatively, the first roller pressing section 61 first descends and presses a certain distance, then rises, and the second roller pressing section 62 descends and presses a certain distance, and so on, through multiple alternating pressing operations by the first roller pressing section 61 and the second roller pressing section 62, so that the material is completely pressed once.

[0078] Therefore, the roll forming assembly 6 has different operating modes, thus enabling it to be used for rolling different products.

[0079] For example, if the product on the glass substrate is a CFG product, the rolling assembly 6 operates in the first mode. When the coating assembly 5 extends a certain length of the intermediate PET film, the first rolling section 61 descends, pressing the film onto the glass substrate on the second platform 4. After the second platform 4 moves a certain distance, the second rolling section 62 descends to begin rolling, and then the first rolling section 61 rises. When it reaches the end of the glass substrate, the first rolling section 61 descends, pressing the intermediate PET film to facilitate the film cutting operation.

[0080] If the product on the glass substrate is a UTG product instead of a CFG product, the roll forming assembly 6 operates in the second mode. In this case, the first roll forming section 61 can also be used for roll forming. By precisely adjusting the pressure of the first roll forming section 61 on the glass substrate, UTG products with different film thicknesses can be obtained. The film thickness uniformity across the entire surface can reach within 5µm, exhibiting high precision.

[0081] Optionally, such as Figures 5 to 7 As shown, the first roller pressing section 61 includes a flexible shaft 611, a rigid shaft 612, and a first mounting base 613. The flexible shaft 611 and the rigid shaft 612 are rotatably mounted on the first mounting base 613. The flexible shaft 611 is located below the rigid shaft 612, and the flexible shaft 611 and the rigid shaft 612 are in contact with each other. The flexible shaft 611 is used to roller press the coated material on the second platform 4. The rigid shaft 612 fits tightly against the flexible shaft 611 to prevent deformation of the flexible shaft 611 over long-term use.

[0082] The second rolling section 62 includes a rolling shaft 621 and a second mounting base 622. The rolling shaft 621 is rotatably mounted on the second mounting base 622. The rolling shaft 621 is used to roll the coating material on the second platform 4. The hardness of the rolling shaft 621 and the hard shaft 612 are both greater than the hardness of the flexible shaft 611. The two ends of the rolling shaft 621 can move relative to each other in the vertical direction. That is, the height of the left and right ends of the rolling shaft 621 can be adjusted to ensure the parallelism of the rolling shaft 621 relative to the glass substrate and improve the uniformity of the entire rolled film surface.

[0083] Optionally, such as Figures 5 to 7 As shown, the roll forming assembly 6 includes a roll forming support frame 63, a first driving member 64, a first sliding plate 65, a second sliding plate 66, a second driving member 67, and a third driving member 68.

[0084] The roller pressing support frame 63 is located on the machine frame 10. The roller pressing support frame 63 can be composed of a horizontal plate and two vertical plates on the left and right sides to form a support frame for the second platform 4 to pass through. The vertical plates are provided with reinforcing ribs between them and the machine frame 10.

[0085] A first driving member 64 is disposed on the roller pressing support frame 63 and is connected to the first roller pressing part 61. The first driving member 64 can be a cylinder, and drives the first roller pressing part 61 to rise and fall. There are two first driving members 64, which are arranged opposite each other in the left-right direction and are respectively connected to the left and right ends of the first mounting base 613. Furthermore, the roller pressing support frame 63 is provided with linear slide rails corresponding to the left and right ends of the first mounting base 613. The linear slide rails are arranged in the up-down direction, and the left and right ends of the first mounting base 613 are mounted on the linear slide rails, thereby improving the smoothness and stability of the rising and falling of the first roller pressing part 61.

[0086] A first sliding plate 65 is slidably mounted on the roller support frame 63 in the vertical direction. A second sliding plate 66 is slidably mounted on the first sliding plate 65 in the vertical direction. A follower bearing 661 is provided at the lower part of the second sliding plate 66, which is used to press against the film material on the second platform 4. An elastic element is provided between the second sliding plate 66 and the first sliding plate 65, so that after the first sliding plate 65 slides relative to the second sliding plate 66, the elastic element applies a force to the follower bearing 661 toward the second platform 4. A second driving member 67 is mounted on the roller support frame 63 and is connected to the first sliding plate 65. A third driving member 68 is mounted on the second sliding plate 66 and is connected to the second roller pressing section 62.

[0087] When the second driving member 67 drives the first sliding plate 65 to descend, the first sliding plate 65 and the second sliding plate 66 descend synchronously at first. After descending to a certain height, the follower bearing 661 installed on the second sliding plate 66 first contacts the glass substrate on the second platform 4. At this time, the second driving member 67 continues to drive the first sliding plate 65 to descend, and the second sliding plate 66 no longer moves. That is, the first sliding plate 65 continues to descend relative to the second sliding plate 66, and the spring 662 is compressed. Under the action of the compression force of the spring 662 and the gravity of the second sliding plate 66, the follower bearing 661 is pressed against the glass substrate. Regardless of whether there is a horizontal error in the glass substrate itself, the gap between the second roller pressing part 62 and the glass substrate product remains constant.

[0088] Furthermore, such as Figures 5 to 7 As shown, there are two third driving components 68, which are respectively connected to the left and right ends of the roller shaft 621, thereby realizing the function of independently adjusting the height of the left and right ends of the roller shaft 621.

[0089] The roll forming support frame 63 is equipped with two laser sensors 69, which are arranged opposite each other in the left-right direction. The two laser sensors 69 are used to measure the thickness of the coating material on the left and right sides of the second platform 4, respectively. The two laser sensors 69 correspond one-to-one with and are connected to two third drive components 68. Based on the thickness difference measured by the two laser sensors 69, the two third drive components 68 can automatically and accurately adjust the left and right height of the roll forming shaft 621 to ensure the parallelism of the roll forming shaft 621 relative to the glass substrate and improve the uniformity of the entire roll forming film surface.

[0090] Furthermore, the rolling assembly 6 also includes a grating ruler, which includes a scale grating and two grating reading heads. The scale grating is located between the first sliding plate 65 and the second sliding plate 66, and the two grating reading heads are respectively located on the two third driving members 68, so that the grating ruler and the two third driving members 68 form a closed-loop positioning system.

[0091] It is understood that the first drive component 64, the second drive component 67, and the third drive component 68 are all servo drives. To ensure the accuracy of the roller shaft 621 itself, grating reading heads are installed on both third drive components 68. A scale grating is installed between the first sliding plate 65 and the second sliding plate 66, so that the grating scale forms a closed loop with the servo systems of the two third drive components 68. This allows the roller shaft 621 to achieve repeatability and positioning accuracy at the μm level, significantly improving film thickness uniformity and meeting the requirement of 10 μm film thickness uniformity across the entire surface.

[0092] In some embodiments, such as Figures 8 to 11 As shown, the coating assembly 5 includes an unwinding section 51, a first winding section 52, a second winding section 53, a cutter section 54, and a coating support frame 55.

[0093] The coating support frame 55 is located on the frame 10. The coating support frame 55 can also be composed of a horizontal plate and two vertical plates on the left and right to form a support frame for the passage of the second platform 4. Reinforcing ribs are provided between the vertical plates and the frame 10. A dustproof plate 551 is provided between the two vertical plates. The main function of the dustproof plate 551 is to prevent foreign objects from the unwinding and winding mechanism from falling onto the glass substrate.

[0094] The first winding section 52 is located in front of the unwinding section 51, and the second winding section 53 and the cutter section 54 are located behind the unwinding section 51. The second winding section 53 is located above the unwinding section 51, and the cutter section 54 is located below the unwinding section 51. The unwinding section 51 is used to hold a film roll with three layers. The first outer layer film 501 of the film roll is wound up by the first winding section 52, and the second outer layer film 502 of the film roll is wound up by the second winding section 53, so that the middle layer film 503 of the film roll covers the material on the second platform 4 and the film is cut by the cutter section 54. The entire PET film is divided into three layers, and only the middle layer PET film is used for lamination. This is to prevent foreign matter from adhering to the PET film and affecting the film surface effect.

[0095] Optionally, such as Figures 8 to 11 As shown, the unwinding section 51 includes an unwinding motor 511, a locking member 512, and an air shaft 513. The unwinding motor 511 and the locking member 512 are mounted on the film-coating support frame 55. The air shaft 513 extends in the left-right direction. One end of the air shaft 513 is connected to the unwinding motor 511, and the other end of the air shaft 513 is detachably connected to the locking member 512. Limiting discs 514 are slidably provided at both ends of the air shaft 513.

[0096] The air shaft 513 is a shaft whose surface protrudes after being inflated under high pressure. After deflating, the surface quickly retracts. The PET film is placed on the air shaft 513 and fixed to the unwinding section 51 by inflation and deflation. The limiting plate 514 is used to adjust the left and right position of the PET film on the air shaft 513. The unwinding motor 511 rotates the air shaft 513 through a synchronous pulley. The air shaft 513 can be easily disassembled by the tightening knob on the locking part 512, facilitating the loading and unloading of the PET film.

[0097] Optionally, such as Figures 8 to 11 As shown, the first winding section 52 includes a first winding shaft 521, a first transition shaft 522, and a first winding motor 523. The first winding shaft 521 and the first transition shaft 522 are rotatably mounted on the base and extend in the left-right direction. The first winding shaft 521 is located in front of the air shaft 513, and the height of the first winding shaft 521 is approximately the same as the height of the air shaft 513. The first transition shaft 522 is located between the first winding shaft 521 and the air shaft 513, and is located below the first winding shaft 521, so that the first outer layer film 501 of the film roll is wound onto the first winding shaft 521 via the first transition shaft 522. The first winding motor 523 is connected to the first winding shaft 521 and the first transition shaft 522 via a belt, and synchronously drives both to rotate.

[0098] Furthermore, such as Figures 8 to 11 As shown, the first winding section 52 further includes a pressing cylinder 524, a pressing shaft plate 525, and a pressing shaft 526. The pressing cylinder 524 is mounted on the film-coating support frame 55 via a cylinder seat, and the pressing shaft plate 525 is connected to the pressing cylinder 524. The pressing shaft 526 is rotatably mounted on the pressing shaft plate 525, and is arranged radially along the first transition shaft 522 at intervals from the first transition shaft 522. The pressing cylinder 524 drives the pressing shaft 526 to move towards or away from the first transition shaft 522, so that the first outer film 501 of the film roll is pressed between the pressing shaft 526 and the first transition shaft 522.

[0099] At the start of the lamination process, the first outer film 501 is fixed to the first take-up shaft 521. The clamping cylinder 524 extends and presses the first outer film 501 between the first transition shaft 522 and the clamping shaft 526. The first take-up motor 523 drives the first transition shaft 522 to rotate, and drives the first take-up shaft 521 to rotate via a belt, thereby performing a take-up action on the first outer film 501.

[0100] Similarly, the second winding section 53 can be understood as being positioned opposite the first winding section 52. For example... Figures 8 to 11As shown, the second take-up section 53 includes a second take-up shaft 531, a second transition shaft 532, and a second take-up motor 533. The second take-up shaft 531 and the second transition shaft 532 are rotatably mounted on the base and extend in the left-right direction. The second take-up shaft 531 is located behind the air shaft 513, and its height is greater than that of the air shaft 513. The second transition shaft 532 is located between the second take-up shaft 531 and the air shaft 513 and is located below the air shaft 513, so that the film roll can be peeled off the second outer film 502 through the second transition shaft 532 and wound back onto the second take-up shaft 531. The height of the second transition shaft 532 is less than that of the first transition shaft 522. The second take-up motor 533 is connected to the second take-up shaft 531 and the second transition shaft 532 via a belt.

[0101] When the lamination begins, the second outer film 502 is fixed on the second take-up shaft 531. The first take-up motor 523 synchronously drives the second transition shaft 532 and the second take-up shaft 531 to rotate, thereby performing the take-up action of the second outer film 502.

[0102] Optionally, such as Figures 8 to 11 As shown, the cutting section 54 includes a peeling plate 540, which is disposed on the film support frame 55. The peeling plate 540 extends in the left-right direction and is located behind the second winding shaft 531. The height of the peeling plate 540 is less than the height of the second transition shaft 532, so that the film roll is peeled off by the peeling plate 540 to peel out the first outer film 501 and the middle film 503. The first outer film 501 is wound onto the first winding shaft 521 by the first transition shaft 522, and the middle film 503 covers the glass substrate.

[0103] Furthermore, such as Figures 8 to 11 As shown, the cutter section 54 includes a first support shaft 541 and a second support shaft 542, which are disposed on the base and extend in the left-right direction. The first support shaft 541 is located between the peeling plate 540 and the first transition shaft 522, so that the first outer layer film 501 of the film roll passes sequentially through the first support shaft 541 and the first transition shaft 522 to the first winding shaft 521. The second support shaft 542 is located between the peeling plate 540 and the second transition shaft 532, so that the first outer layer film 501 and the middle layer film 503 of the film roll pass through the second support shaft 542 to the peeling plate 540. The first support shaft 541 and the second support shaft 542 provide support to ensure the stability of the winding process.

[0104] Optionally, such as Figures 8 to 11As shown, the cutting unit 54 includes a movable frame 543, a single-axis cylinder 544, a cutting slide rail 545, a cutting cylinder 546, and a cutting blade 547. The movable frame 543 is mounted on the film-coating support frame 55 and is movable in the front-to-back direction. The single-axis cylinder 544 is connected to the movable frame 543. The cutting slide rail 545 is mounted on the movable frame 543 and extends in the left-to-right direction. The cutting cylinder 546 is mounted on the cutting slide rail 545 and is connected to the cutting blade 547 to drive the cutting blade 547 to move in the up-down direction.

[0105] The operating sequence of the cutting unit 54 is as follows: the single-axis cylinder 544 extends, driving the moving frame 543 forward, and simultaneously causing the components on the moving frame 543 to extend forward; the cutting cylinder 546 extends, driving the cutter 547 to descend and cut the interlayer film 503; the cutter 547 moves left and right on the cutting slide rail 545, cutting the entire interlayer film 503. After the film cutting action is completed, the cutting cylinder 546 and the single-axis cylinder 544 retract, and the cutting unit 54 returns to the starting position.

[0106] Furthermore, such as Figures 8 to 11 As shown, the cutter section 54 includes a pressure plate cylinder 548 and a pressure plate 549. The pressure plate cylinder 548 is located on the movable frame 543 and is connected to the pressure plate 549. The pressure plate cylinder 548 is used to drive the pressure plate 549 to move in the up and down direction so that the film roll is pressed between the pressure plate 549 and the peeling plate 540.

[0107] Understandably, during the cutting process 547, the pressure plate cylinder 548 extends to press the middle layer film 503 between the pressure plate 549 and the peeling plate 540, ensuring the flatness of the film during cutting.

[0108] In some embodiments, such as Figure 1 and Figure 12 As shown, the translation component 3 includes a translation frame 31 and an extraction part 32. The translation frame 31 is movably mounted on the frame 10 in the front-to-back direction. The extraction part 32 is mounted on the translation frame 31 and is movable in the left-to-right and up-to-down directions. There are two translation components 3, which are arranged opposite each other in the left-to-right direction.

[0109] The main function of the translation component 3 is to remove the glass substrate after dispensing from the first platform 1 and place it on the second platform 4. There are two sets of translation components 3, with the left and right sets working simultaneously to pick up the left and right sides of the glass substrate and move it in the forward and backward and up and down directions, respectively.

[0110] Optionally, such as Figure 12As shown, the translation frame 31 includes a front-to-back translation servo module 311, a mounting plate 312, a vertical translation servo module 313, and a translation frame cable sheet metal 314. The front-to-back translation servo module 311 is mounted on the frame 10, the mounting plate 312 is mounted on the front-to-back translation servo module 311, the vertical translation servo module 313 is mounted on the mounting plate 312, and the translation frame cable sheet metal 314 is mounted on the frame 10 and adjacent to the front-to-back translation servo module 311. The extraction unit 32 includes a slide cylinder 321 and a vacuum suction component 322. The slide cylinder 321 is mounted on the vertical translation servo module 313, and the vacuum suction component 322 is mounted on the slide cylinder 321.

[0111] The forward and backward translation servo modules 311 of the translation components 3 on both sides are activated simultaneously. The translation frame 31 moves to the material picking position of the first platform 1, the slide cylinder 321 extends, and at the same time, the up and down translation servo module 313 drives the vacuum adsorption component 322 to descend and contact the glass substrate. The vacuum generator of the vacuum adsorption component 322 generates a vacuum, and the vacuum adsorption component 322 adsorbs the glass substrate. Then, the translation frame 31 moves to the material placement position of the second platform 4, the vacuum adsorption component 322 breaks the vacuum, the slide cylinder 321 retracts, and the glass substrate is placed on the second platform 4.

[0112] In some embodiments, such as Figure 13 and Figure 14 As shown, the first platform 1 includes a first support frame 11, a first adsorption part 12, and a first lifting part 13. The first support frame 11 is movably mounted on the frame 10 in the front-to-back direction, and the first support frame 11 drives the entire platform to move back and forth via a first front-to-back servo slide 111. The first adsorption part 12 is mounted on the first support frame 11, and the first lifting part 13 is movably mounted on the first support frame 11 in the vertical direction. A portion of the first lifting part 13 can slide through the first adsorption part 12.

[0113] The first adsorption unit 12 is made of high-precision aluminum plate. The size and layout of the vacuum ports on it require careful calculation to ensure both the adsorption of the glass substrate and that the glass substrate does not deform during adsorption, thus avoiding affecting the uniformity of adhesive dispensing. The vacuum generator of the first adsorption unit 12 generates a vacuum, adsorbing the glass substrate onto the plate. The first adsorption unit 12 is equipped with a guide wheel plate 121, guide wheels 122, a positioning cylinder 123, and a positioning block 124 for precise positioning of the glass substrate.

[0114] The first lifting part 13 includes a first lifting pin 131, a first lifting pin plate 132 and a first lifting cylinder 133, which are used to lift and lower the glass substrate, corresponding to the upstream and downstream robotic arms picking up and placing materials.

[0115] In some embodiments, such as Figure 15 and Figure 16As shown, the second platform 4 includes a second support frame 41, a second adsorption part 42, and a second lifting part 43. The second support frame 41 is movably mounted on the frame 10 in the front-to-back direction. The second adsorption part 42 is mounted on the second support frame 41, and the level of the second adsorption part 42 is adjustable. The second lifting part 43 is movably mounted on the second support frame 41 in the up-down direction, and a portion of the second lifting part 43 can slide through the second adsorption part 42.

[0116] The glass substrate is placed on the second platform 4 and rolled. The second adsorption part 42 is made of marble slab with a flatness requirement of less than 5 μm. It is equipped with vacuum ports, and the size and number of the holes are precisely calculated. The vacuum generator of the second adsorption part 42 generates a vacuum, so that even if the glass substrate has a certain degree of warping, it can still adsorb the glass substrate onto the second platform 4.

[0117] The second adsorption unit 42 is equipped with two sets of detection mechanisms, one for the left and one for the right, consisting of a base 421 and a digital micrometer head 422. These mechanisms are used to detect the parallelism of the left and right sides of the roller shaft 621 relative to the second platform 4. When the roller shaft 621 contacts the digital micrometer head 422, the data displayed by the two digital micrometer heads 422 are observed, and the left and right ends of the roller shaft 621 are precisely adjusted based on the difference.

[0118] The second support frame 41 is equipped with four sets of adjustment mechanisms consisting of an adjustment flange plate 411, an adjustment screw 412, a steel ball 413, and a steel ball upper plate 414, which are used to adjust the level of the second platform 4. The adjustment screw 412 is equipped with a high-precision fine thread. When rotating, the adjustment screw 412 can move slightly up and down under the action of the steel ball 413.

[0119] Other aspects of the second platform 4 are similar to those of the first platform 1, and will not be elaborated on here.

[0120] In some embodiments, the entire device requires high precision and stability during coating, and must be free from any vibration. Therefore, predicting the vibration of the device itself is crucial. If resonance occurs, it can cause significant vibration and serious damage to components. Therefore, the frame 10 is constructed from welded square tubing, with a marble surface on the upper plane. Marble surfaces offer advantages such as high precision, good rigidity, and low vibration. Resonance analysis at different frequencies consistently meets the device's precision requirements.
