Description

Technical Field

[0001] The present invention relates to the technical field related to barrier composite film processing, and in particular to a glue layer curing device and a curing process thereof for a barrier composite film. Background Art

[0002] In recent years, with the continuous application of flexible materials in the fields of display and solar energy, more and more research has been conducted on thin film materials with high water vapor and oxygen barrier properties. The commonly used method is to plate oxides (such as silicon oxide, aluminum oxide, etc.) on polyester film by vapor deposition (CVD), plasma enhanced chemical vapor deposition (PECVD) or magnetron sputtering (Sputter). These barrier films have a variety of applications in the display, lighting and solar energy markets as glass alternative flexible materials. In the processing of barrier composite films, a glue layer is applied on one side of the barrier composite film for composite pasting of multi-layer materials, so a glue curing device is required.

[0003] The existing glue curing devices are usually divided into two types: UV curing and high-temperature curing. Especially in the process of high-temperature curing, the temperature and heating time will affect the curing state of the glue. The currently used high-temperature curing glue curing devices can usually only adjust the curing effect of the glue layer by adjusting the heating power and heating time of the heat source. Since the heating power adjustment of the heat source has hysteresis in the application process and the adjustment range is large, it cannot be adjusted quickly and accurately during the debugging process, so there are disadvantages in use. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a glue layer curing device and a curing process for a barrier composite film, so as to solve the problem mentioned in the above background that the existing high-temperature curing glue curing device cannot be adjusted quickly and accurately during the debugging process because the heating power adjustment of the heat source has hysteresis during the application process and the adjustment range is large. Therefore, there are disadvantages in use.

[0010] Furthermore, a distance detector is installed on the top of the top frame, and four distance detectors are symmetrically distributed.

[0011] Furthermore, the partition is connected to the lifting frame by sliding connection, and the lifting frame, the first guide roller, the first support plate, the second support plate and the first regulating cylinder constitute a lifting structure.

[0012] Furthermore, the connection modes of the transfer rod to the second support plate and the slide rod are all rotational connections, and the connection mode of the slide rod to the slide seat is sliding connection, and the second support plate, the transfer rod, the slide rod and the slide seat form a sliding structure.

[0013] Furthermore, the connection mode between the slider and the engaging plate is a sliding connection, and the connection mode between the slider and the spring rod is a rotational connection, and the slider, the support rod, the push rod and the tension roller form a sliding structure.

[0014] Furthermore, the push rod and the slider are connected in a sliding manner, and the push rod, the support rod, the tension roller and the engagement block form a telescopic structure.

[0015] Furthermore, a mounting plate is installed at one end of the interior of the mounting frame, and two second regulating cylinders are symmetrically installed on the mounting plate, and the extending ends of the two second regulating cylinders are connected to the movable frame;

[0016] Furthermore, two groups of rotating brackets are symmetrically installed at both ends of the movable frame, and each group of rotating brackets is symmetrically provided with two rotating brackets, and a spring plate is installed between the two rotating brackets of the same group;

[0017] Furthermore, the end of each rotating bracket is rotatably connected to one end of a pressure roller, and the rotating bracket, the pressure roller, the movable frame and the second regulating cylinder are in a sliding structure.

[0018] Furthermore, the connection mode between the rotating bracket and the movable bracket is a rotating connection, and the rotating bracket, the spring plate and the pressure roller form a rotating structure.

[0019] A curing process of a glue layer curing device for a barrier composite film:

[0020] Step 1: First, introduce the barrier composite film to be processed from one end where the glue coating mechanism is installed, then pass the barrier composite film from bottom to top around a second guide roller, then continue to pass the barrier composite film upward around a first guide roller, then pass the barrier composite film through both ends of the top frame, and pass the barrier composite film from top to bottom around another first guide roller, finally overlap the barrier composite film and the composite layer film material to be used and pass them between the pressure roller and the conveying roller at the same time;

[0021] Step 2: Turn on the external power supply, start the two second regulating cylinders at the same time, push the movable frame to slowly translate, until the two pressing rollers press the barrier composite film and the composite layer film material to be used on the conveying roller, then start the motor to drive the conveying roller to start rotating, and then drive the barrier composite film and the composite layer film material to be used to start conveying at the same time, then the barrier composite film is gradually tightened until the barrier composite film is in close contact with the gluing mechanism and the first guide roller at the same time, and in this process, the pressure makes the barrier composite film and the composite layer fit closely;

[0022] Step 3: Start the glue coating mechanism to evenly coat the glue on the barrier composite film, and start the heater at the same time. When the barrier composite film coated with glue passes through the top frame, the heater dries the glue layer on the barrier composite film.

[0023] Step 4: When the distance between the heater and the barrier composite film needs to be increased, the two first regulating cylinders are started at the same time, and the first support plate drives the two second support plates and the two lifting frames, and the first guide rollers installed between the two lifting frames are synchronously driven to start to descend synchronously; in this process, the distance between the first guide roller and the heater gradually increases, thereby increasing the distance between the barrier composite film and the heater, and at the same time the overall tension of the barrier composite film is reduced;

[0024] Step 5: When the second support plate descends, the two transfer rods connected at the bottom will be driven to flip to both ends at the same time, thereby pushing the correspondingly connected slide rod and spring rod. Due to the limitation of the slide seat, the sliding tracks of the slide rod and spring rod remain horizontal; while the spring rod slides, the correspondingly connected slide bar starts to slide along the meshing plate, thereby pushing the tension roller to gradually approach the barrier composite film;

[0025] Step 6: When the tension roller contacts the barrier composite film, the tension of the barrier composite film gradually increases, and then the pressure applied to the tension roller gradually increases. At this time, the reset spring with a lower elastic coefficient gradually begins to shrink. As the reset spring shrinks, the push rod gradually moves toward the inside of the slider, and at the same time pushes the meshing block to gradually approach the meshing plate. When the meshing block is fully meshed with the meshing plate, the slider no longer slides to avoid excessive squeezing of the barrier composite film. Then, the spring rod with a higher elastic coefficient provides position compensation for the movement of the transfer rod through its own contraction.

[0026] Step 7: When it is necessary to increase the distance between the heater and the barrier composite film, start the two first adjusting cylinders at the same time, cooperate with the first support plate to drive the two second support plates and the two lifting frames, and synchronously drive the first guide rollers installed between the two lifting frames to start rising synchronously; in this process, the distance between the first guide roller and the heater gradually decreases, thereby reducing the distance between the barrier composite film and the heater, and at the same time the overall tension of the barrier composite film increases, and in the process of the second support plate rising, it will drive the two transfer rods connected to the bottom to flip inward at the same time, thereby pulling the corresponding connected sliding rod and spring rod, and while the spring rod slides, the corresponding connected slider is pulled to start sliding along the meshing plate, thereby pushing the tension roller to gradually approach the barrier composite film, because the top of the meshing plate is a ratchet structure, when the slider shrinks and slides, it will drive the meshing block to cooperate with the contraction and rebound of the reset spring to continuously and indirectly engage, thereby driving the tension roller to gradually move away from the barrier composite film, thereby causing the pressure applied by the tension roller to the barrier composite film to continuously decrease, so as to balance the tension of the barrier composite film.

[0027] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0028] 1. In the present invention, a lifting frame and a first guide roller are provided, and the lifting frame and the first guide roller are installed inside the top frame. During the processing, the barrier composite film coated with glue passes horizontally under the heater close to the first guide roller, and the glue on the surface of the barrier composite film is dried and cured by the heater. The height of the lifting frame and the first guide roller are synchronously adjusted by two first adjusting cylinders, which can accurately control the distance between the barrier composite film and the heater, facilitate accurate adjustment of the heating efficiency of the barrier composite film, and cooperate with adjusting the heating power of the heater to accurately adjust the curing effect of the glue layer on the surface of the barrier composite film.

[0029] 2. In the present invention, during the processing, the barrier composite film is always kept in a taut state, and in the initial state, the lifting frame and the first guide roller are kept in the highest position. At this time, the two tension rollers are not in contact with the barrier composite film. During the debugging process, when the lifting frame and the first guide roller are lowered, the tension of the barrier composite film will be reduced. During the synchronous lowering of the second support plate and the lifting frame, the two transfer rods connected at the bottom will be driven to flip to both ends at the same time, thereby pushing the correspondingly connected sliding rod and spring rod. When the spring rod slides, the correspondingly connected sliding rod starts to slide along the meshing plate, thereby pushing the tension roller gradually close to the barrier composite film. When the tension roller contacts the barrier When the composite film is laminated, the tension of the barrier composite film gradually increases, and then the pressure applied to the tension roller gradually increases. At this time, the return spring with a lower elastic coefficient gradually begins to shrink. As the return spring shrinks, the push rod gradually moves toward the inside of the slider, and at the same time pushes the meshing block gradually close to the meshing plate. When the meshing block is fully meshed with the meshing plate, the slider no longer slides to avoid excessive extrusion of the barrier composite film. Subsequently, the spring rod with a higher elastic coefficient provides position compensation for the movement of the transfer rod through its own contraction. During the entire adjustment process, it can be ensured that the barrier composite film always maintains sufficient tension and will not be excessively extruded, thereby improving ease of use.

[0030] 3. In the present invention, a movable frame, a rotating bracket, a pressure roller and a spring plate are provided. Since the barrier composite film is a polymer material, if the distance between the pressure roller and the conveying roller is too close, it will cause excessive pressure on the barrier composite film, which will easily cause the thickness of the barrier composite film to decrease, affecting the product quality. The present invention adjusts the distance between the pressure roller and the conveying roller by two adjusting cylinders, and in the process of adjustment, when the pressure roller contacts the conveying roller, if the pressure continues to increase, the two pressure rollers will flip to both sides, and at the same time drive the rotating bracket to rotate synchronously and start to stretch the spring plate, and absorb excess pressure through the deformation of the spring plate, so as to avoid the pressure roller and the conveying roller being too close due to the long stroke of the adjusting cylinder. At the same time, the two pressure rollers cooperate with the conveying roller to improve the bonding effect between the barrier composite film and the composite layer during processing.

A distance detector 18 is installed on the top of the top frame 2, and four distance detectors 18 are symmetrically distributed.

[0049] More specifically, in the initial state, the lifting frame 5 is at the highest position, and at this time, the distance between the top of the first guide roller 6 and the heater 3 is the smallest.

[0050] As a further illustration of this embodiment, the top of the engagement plate 15 is a ratchet structure, and the bottom of the engagement block 21 is generally a ratchet structure.

[0051] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in this embodiment, the partition 4 is connected to the lifting frame 5 by sliding connection, and the lifting frame 5, the first guide roller 6, the first support plate 8, the second support plate 9 and the first regulating cylinder 7 constitute a lifting structure.

[0052] More specifically, each first guide roller 6 can rotate independently, and the first guide roller 6 is lifted and lowered synchronously with the two lifting frames 5 .

[0053] As a further explanation of this embodiment, two lifting frames 5 are driven to rise and fall synchronously by two first regulating cylinders 7 at the same time.

[0054] Please refer to Fig. 9 and Fig.10 As shown, in this embodiment, the connection mode between the transfer rod 10 and the second support plate 9 and the slide rod 11 is a rotational connection, and the connection mode between the slide rod 11 and the slide seat 12 is a sliding connection. At the same time, the second support plate 9, the transfer rod 10, the slide rod 11 and the slide seat 12 form a sliding structure.

[0055] Specifically, when the second support plate 9 descends, the bottoms of the two correspondingly connected transfer rods 10 will be driven to flip outward at the same time, thereby pushing the correspondingly connected sliding rods 11 to slide in the same direction.

[0056] As a further explanation of this embodiment, the sliding track of the sliding rod 11 is limited by the sliding seat 12 .

[0057] Please refer to Fig.12 As shown, in this embodiment, the connection mode between the slider 14 and the engaging plate 15 is a sliding connection, and the connection mode between the slider 14 and the spring rod 13 is a rotational connection. At the same time, the slider 14, the support rod 16, the push rod 17 and the tension roller 20 form a sliding structure.

[0058] Specifically, when the slide bar 11 slides, it cooperates with the spring bar 13 to drive the slider 14 to slide along the engagement plate 15 synchronously.

[0059] As a further explanation of this embodiment, the slider 14 slides along the engaging plate 15 while driving the support rod 16 and the tension roller 20 to translate synchronously.

[0060] Please refer to Fig.12 As shown, in this embodiment, the push rod 17 and the slider 14 are connected in a sliding manner, and the push rod 17, the support rod 16, the tension roller 20 and the engagement block 21 form a telescopic structure.

[0061] More specifically, in the initial state, the engaging block 21 and the engaging plate 15 are not in contact with each other.

[0062] As a further explanation of this embodiment, as the retraction distance of the return spring 19 increases, the distance between the engagement block 21 and the engagement plate 15 will gradually decrease until the engagement block 21 and the engagement plate 15 are engaged with each other.

[0063] Please refer to Fig.11 As shown, in this embodiment, a mounting plate 27 is installed at one end of the interior of the mounting frame 1, and two second adjusting cylinders 28 are symmetrically installed on the mounting plate 27, and the extending ends of the two second adjusting cylinders 28 are connected to the movable frame 29; two groups of rotating brackets 30 are symmetrically installed at both ends of the movable frame 29, and each group of rotating brackets 30 is symmetrically distributed with two, and a spring plate 32 is installed between the two rotating brackets 30 of the same group; the end of each rotating bracket 30 is rotatably connected to one end of a pressure roller 31, and the rotating bracket 30, the pressure roller 31, the movable frame 29 and the second adjusting cylinder 28 are in a sliding structure.

[0064] More specifically, the distance between the pressure roller 31 and the conveying roller 25 is adjusted by two second adjusting cylinders 28 .

[0065] As a further explanation of this embodiment, in the initial state, the spring plate 32 remains in a contracted state, and at this time, the distance between the two pressure rollers 31 is the smallest.

[0066] Please refer to Fig.11 As shown, in this embodiment, the connection mode between the rotating bracket 30 and the movable bracket 29 is a rotating connection, and the rotating bracket 30, the spring plate 32 and the pressure roller 31 form a rotating structure.

[0067] More specifically, the two pressing rollers 31 are symmetrically distributed about the transverse axis of the conveying roller 25 .

[0068] As a further explanation of this embodiment, when the pressure roller 31 is displaced too much, the pressure roller 31 will roll along the surface of the conveying roller 25 and stretch the spring plate 32 at the same time. The rebound force generated by the stretching of the spring plate 32 pulls the pressure roller 31 close to the conveying roller 25.

[0069] A curing process of a glue layer curing device for a barrier composite film:

[0070] Step 1: First, introduce the barrier composite film to be processed from one end where the glue coating mechanism 24 is installed, then pass the barrier composite film from bottom to top around a second guide roller 23, and then continue to pass the barrier composite film upward around a first guide roller 22, then pass the barrier composite film through both ends of the top frame 2, and pass the barrier composite film from top to bottom around another first guide roller 22, and finally overlap the barrier composite film and the composite layer film material to be used and pass them between the pressing roller 31 and the conveying roller 25 at the same time;

[0071] Step 2: Turn on the external power supply, start the two second regulating cylinders 28 at the same time, push the movable frame 29 to slowly translate, until the two pressing rollers 31 press the barrier composite film and the composite layer film material to be used on the conveying roller 25, then start the motor 26, drive the conveying roller 25 to start rotating, and then drive the barrier composite film and the composite layer film material to be used to start conveying at the same time, then the barrier composite film is gradually tightened until the barrier composite film is in close contact with the gluing mechanism 24 and the first guide roller 6 at the same time, and in this process, the pressure makes the barrier composite film and the composite layer fit tightly;

[0072] Step 3: Start the glue coating mechanism 24, and evenly coat the glue on the barrier composite film through the glue coating mechanism 24. Simultaneously, start the heater 3, and in the process of the barrier composite film coated with glue passing through the top frame 2, the heater 3 dries the glue layer coated on the barrier composite film.

[0073] Step 4: When the distance between the heater 3 and the barrier composite film needs to be increased, the two first regulating cylinders 7 are started at the same time, and the first support plate 8 drives the two second support plates 9 and the two lifting frames 5, and synchronously drives the first guide roller 6 installed between the two lifting frames 5 to start to descend synchronously; in this process, the distance between the first guide roller 6 and the heater 3 gradually increases, thereby increasing the distance between the barrier composite film and the heater 3, and at the same time the overall tension of the barrier composite film is reduced;

[0074] Step 5: During the descent of the second support plate 9, the two transfer rods 10 connected at the bottom will be driven to flip to both ends at the same time, thereby pushing the correspondingly connected slide rod 11 and spring rod 13. Due to the restriction of the slide seat 12, the sliding tracks of the slide rod 11 and the spring rod 13 remain horizontal; while the spring rod 13 slides, the correspondingly connected slide block 14 will be driven to start sliding along the meshing plate 15, thereby pushing the tension roller 20 to gradually approach the barrier composite film;

[0075] Step 6: When the tension roller 20 contacts the barrier composite film, the tension of the barrier composite film gradually increases, and then the pressure applied to the tension roller 20 gradually increases. At this time, the return spring 19 with a lower elastic coefficient gradually begins to shrink. As the return spring 19 shrinks, the push rod 17 gradually moves toward the inside of the slider 14, and at the same time pushes the meshing block 21 to gradually approach the meshing plate 15. When the meshing block 21 is fully meshed with the meshing plate 15, the slider 14 no longer slides to avoid excessive squeezing of the barrier composite film. Then, the spring rod 13 with a higher elastic coefficient provides position compensation for the movement of the transfer rod 10 through its own contraction.

[0076] Step 7: When the distance between the heater 3 and the barrier composite film needs to be increased, the two first regulating cylinders 7 are started at the same time, and the first support plate 8 drives the two second support plates 9 and the two lifting frames 5, and synchronously drives the first guide roller 6 installed between the two lifting frames 5 to start rising synchronously; in this process, the distance between the first guide roller 6 and the heater 3 is gradually reduced, thereby reducing the distance between the barrier composite film and the heater 3, and at the same time, the overall tension of the barrier composite film is increased, and during the rising process of the second support plate 9, the two transfer rods 10 connected at the bottom are driven to move upward simultaneously. It flips inward, and then pulls the corresponding connected slide rod 11 and spring rod 13. While the spring rod 13 slides, it pulls the corresponding connected slider 14 to start sliding along the meshing plate 15, and then pushes the tension roller 20 to gradually approach the barrier composite film. Since the top of the meshing plate 15 is a ratchet structure, when the slider 14 shrinks and slides, it will drive the meshing block 21 to cooperate with the shrinkage and rebound of the return spring 19 to continuously and indirectly engage, and then drive the tension roller 20 to gradually move away from the barrier composite film, so that the pressure applied to the barrier composite film by the tension roller 20 is continuously reduced to balance the tension of the barrier composite film.

[0077] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.

9. A curing process using the glue layer curing device of the barrier composite film according to any one of claims 1 to 8, characterized in that: Step 1: First, introduce the barrier composite film to be processed from one end where the glue coating mechanism (24) is installed, then pass the barrier composite film from bottom to top around a second guide roller (23), then continue to pass the barrier composite film upward around a first guide roller (22), then pass the barrier composite film through both ends of the top frame (2), and pass the barrier composite film from top to bottom around another first guide roller (22), finally overlap the barrier composite film and the composite layer film material to be used and pass them between the pressure roller (31) and the conveying roller (25) at the same time; Step 2: Connect an external power source and start two second regulating cylinders (28) at the same time, push the movable frame (29) to slowly translate until the two pressing rollers (31) press the barrier composite film and the composite layer film material to be used onto the conveying roller (25), then start the motor (26) to drive the conveying roller (25) to start rotating, thereby driving the barrier composite film and the composite layer film material to be used to start conveying at the same time, then the barrier composite film is gradually tightened until the barrier composite film is in close contact with the gluing mechanism (24) and the first guide roller (6) at the same time, and during this process, the pressure makes the barrier composite film and the composite layer fit tightly; Step 3: Start the glue coating mechanism (24), and evenly coat the glue on the barrier composite film through the glue coating mechanism (24), and simultaneously start the heater (3), and in the process of the barrier composite film coated with glue passing through the interior of the top frame (2), the heater (3) dries the glue layer coated on the barrier composite film; Step 4: When it is necessary to increase the distance between the heater (3) and the barrier composite film, the two first regulating cylinders (7) are started simultaneously, and the first support plate (8) is used to drive the two second support plates (9) and the two lifting frames (5), thereby synchronously driving the first guide roller (6) installed between the two lifting frames (5) to start descending synchronously; during this process, the distance between the first guide roller (6) and the heater (3) gradually increases, thereby increasing the distance between the barrier composite film and the heater (3), and at the same time, the overall tension of the barrier composite film is reduced; Step 5: When the second support plate (9) descends, the two transfer rods (10) connected at the bottom will be driven to flip to both ends at the same time, thereby pushing the correspondingly connected slide rod (11) and spring rod (13). Due to the limitation of the slide seat (12), the sliding tracks of the slide rod (11) and the spring rod (13) remain horizontal; while the spring rod (13) slides, the correspondingly connected slider (14) will start to slide along the meshing plate (15), thereby pushing the tension roller (20) to gradually approach the barrier composite film; Step 6: When the tension roller (20) contacts the barrier composite film, the tension of the barrier composite film gradually increases, and then the pressure applied to the tension roller (20) gradually increases. At this time, the return spring (19) with a lower elastic coefficient gradually begins to shrink. As the return spring (19) shrinks, the push rod (17) gradually moves toward the inside of the slider (14), and at the same time pushes the meshing block (21) gradually close to the meshing plate (15). When the meshing block (21) is fully meshed with the meshing plate (15), the slider (14) no longer slides to avoid excessive squeezing of the barrier composite film. Then, the spring rod (13) with a higher elastic coefficient provides position compensation for the movement of the transfer rod (10) through its own shrinkage. Step 7: When it is necessary to increase the distance between the heater (3) and the barrier composite film, the two first regulating cylinders (7) are started at the same time, and the first support plate (8) drives the two second support plates (9) and the two lifting frames (5), and synchronously drives the first guide roller (6) installed between the two lifting frames (5) to start rising synchronously; during this process, the distance between the first guide roller (6) and the heater (3) gradually decreases, thereby reducing the distance between the barrier composite film and the heater (3), and at the same time, the overall tension of the barrier composite film increases, and during the rising process of the second support plate (9), it drives the two transfer rods (10) connected at the bottom to move upward simultaneously. The spring rod (13) is turned inward, thereby pulling the correspondingly connected slide rod (11) and spring rod (13). When the spring rod (13) slides, the correspondingly connected slide rod (14) is pulled to start sliding along the meshing plate (15), thereby pushing the tension roller (20) to gradually approach the barrier composite film. Since the top of the meshing plate (15) is a ratchet structure, when the slide rod (14) shrinks and slides, it will drive the meshing block 2 (1) to cooperate with the shrinkage and rebound of the return spring (19) to continuously and indirectly engage, thereby driving the tension roller (20) to gradually move away from the barrier composite film, thereby causing the pressure applied by the tension roller (20) to the barrier composite film to continuously reduce, so as to balance the tension of the barrier composite film.
