Description

Technical Field

[0001] This utility model relates to the field of thin film imprinting technology, and in particular to a thin film imprinting system. Background Technology

[0002] Roll-to-roll nanoimprinting is a novel material preparation technology that can be used to continuously produce high-quality, high-precision micro- and nanostructures. However, the seam problem in roll-to-roll nanoimprinting can lead to discontinuities in the film pattern. The seam problem in roll-to-roll nanoimprinting mainly stems from insufficient mold splicing precision, uneven material filling, and stress release during curing. Therefore, the micro- and nanostructured films with seams produced will limit the use of the products. Utility Model Content

Figure 2 This is a top view schematic diagram of the first pattern formed by the film imprinting system of this application on a film. Figure 3 yes Figure 2 The diagram shows a cross-sectional view of the thin film. Figure 4 and Figure 5 This is a top view schematic diagram of the film imprinting system of this application forming a second pattern on a film. Figure 6a yes Figure 4 The diagram shows a cross-sectional view of the thin film. Figure 6b yes Figure 5 Please refer to the schematic diagram of the partial cross-sectional structure of the thin film shown. Figures 1 to 6b The film imprinting system includes a vertical plate 11 and a first gluing unit 13, a first imprinting unit 15, a second gluing unit 16 and a second imprinting unit 17 mounted on the vertical plate 11. The film 31 to be imprinted passes through the first gluing unit 13, the first imprinting unit 15, the second gluing unit 16 and the second imprinting unit 17 in sequence.

[0075] The first adhesive unit 13 is configured to apply a first adhesive layer 41 to a plurality of first regions of the film 31, the plurality of first regions being arranged at intervals along the length of the film 31, and a second region being formed between every two adjacent first regions.

[0076] The first imprinting unit 15 is configured to form a first pattern 411 on each of the first adhesive layers 41;

[0077] The second adhesive unit 16 is configured to apply a second adhesive layer 42 in the second region;

[0078] The second imprinting unit 17 is configured to form a second pattern 421 on the second adhesive layer 42, wherein a plurality of first patterns 411 and a plurality of second patterns 421 are combined to form a continuous and uninterrupted pattern layer.

[0079] The step of forming a continuous and uninterrupted pattern layer on the surface of the film 31 using the film imprinting system of this application includes:

[0080] Step 1: Control the first adhesive application unit 13 to apply the first adhesive layer 41 to multiple first regions of the film 31.

[0081] Step two, control the first imprinting unit 15 to imprint the first pattern 411 on each of the first adhesive layers 41, referring to... Figure 2 and Figure 3 .

[0082] Step 3: Control the second adhesive application unit 16 to apply a second adhesive layer 42 to multiple second regions of the film 31. The second adhesive layer 42 and the first adhesive layer 41 are located on the same surface of the film 31, and the two sides of the second adhesive layer 42 are joined to or overlapped with the edges of two adjacent first adhesive layers 41, such as... Figure 6a and Figure 6b As shown.

[0083] Step four: Control the second imprinting unit 17 to imprint the second pattern 421 on each of the second adhesive layers 42, referring to... Figure 4 , Figure 5 , Figure 6a and Figure 6b .

[0084] The film imprinting system of this application can achieve seamless imprinting, that is, the second pattern 421 is seamlessly connected to the two adjacent first patterns 411, or the two sides of the second pattern 421 overlap with the edges of the two first patterns 411 to form a continuous and uninterrupted pattern layer, thereby producing film materials with large-size patterns, which has a wide range of applications. The increased effective pattern area (corresponding to the area of ​​the second pattern 421 in the second adhesive layer 42) avoids waste of film material. At the same time, the film imprinting system of this application has the advantages of high imprinting accuracy, fast production speed, and high efficiency. In addition, the surface of the film 31 of this application is only provided with one adhesive layer (a continuous adhesive layer formed by the first adhesive layer 41 and the second adhesive layer 42), and the overall thickness is relatively thin, which helps to save raw materials and reduce production costs.

[0085] Optionally, the thin film imprinting system is capable of high-quality, high-precision micro / nano structure imprinting. The first pattern 411 and / or the second pattern 421 imprinted thereon are, for example, micro / nano structures. The cross-section of the micro / nano structure includes any one or a combination of arc, triangle, trapezoid, step, or rectangle. In this embodiment, the cross-section of the micro / nano structure is rectangular, but it is not limited thereto.

[0086] Optionally, the area ratio of the first region to the second region on the thin film 31 is 9:1, but it is not limited to this.

[0087] Optionally, such as Figure 6a As shown, the thickness of the pattern layer is uniform throughout, meaning that the thickness of the first adhesive layer 41 and the second adhesive layer 42 on which the pattern layer is formed is the same. In this embodiment, when the second adhesive application unit 16 applies adhesive to the second region of the film 31, the second adhesive layer 42 covers the entire second region, and the two sides of each second adhesive layer 42 are joined with the edges of two adjacent first adhesive layers 41 to form a single layer of uniformly thick cured adhesive.

[0088] Optionally, such as Figure 6b As shown, the two sides of the second adhesive layer 42 overlap with the edges of two adjacent first adhesive layers 41 to form an overlapping area 42a. The overlapping area 42a has a second pattern 421 formed thereon. The thickness h2 of the overlapping area 42a is greater than the thickness h1 of the first adhesive layer 41 and the second adhesive layer 42. In this embodiment, when the second adhesive application unit 16 applies adhesive to the second region of the film 31, the second adhesive layer 42 will cover the entire second region, and the two sides of each second adhesive layer 42 will cover the edges of two adjacent first adhesive layers 41 to form an overlapping area 42a. The micro-nano structure grooves at the edges of the first adhesive layer 41 will be filled by the second adhesive layer 42. Then, the second imprinting unit 17 imprints the second pattern 421 in the overlapping area 42a. The thickness h2 of the overlapping area 42a will be greater than the thickness h1 of other areas.

[0089] Optionally, during the imprinting process of the second imprinting unit 17, a liquid second adhesive layer 42 covers the first adhesive layer 41 of the overlapping area 42a. Below the liquid second adhesive layer 42 is a cured first pattern 411 with a certain thickness. The second area only has the liquid second adhesive layer 42. Due to the extrusion action, the thickness h2 of the overlapping area 42a is the largest at the adjacent edge of the first area. Moving towards the second area, the thickness h2 of the overlapping area 42a gradually decreases to h1, forming a smooth transition area. The overlapping area 42a has no impact on the overall visual effect of the product. Specifically, h2 equals 2h1. If h2 is too high, it will cause obvious protrusions in the film pattern layer, affecting the flatness and visual effect of the film.

[0090] Optionally, the thickness h2 of the overlapping region 42a is 100nm to 100μm, for example, 200nm, 500nm, 800nm, 1μm, 20μm, 50μm, or 80μm.

[0091] Optionally, the thickness h1 of the first adhesive layer 41 and the second adhesive layer 42 is 50nm to 50μm, for example 100nm, 500nm, 1μm, or 20μm.

[0092] Optionally, such as Figure 1As shown, a first guide roller 111 is provided on the upright plate 11, which is adjacent to the first gluing unit 13. The film 31 passes between the first gluing unit 13 and the first guide roller 111. In this embodiment, the upright plate 11 is arranged in a vertical direction, the end of the first guide roller 111 is rotatably connected to the upright plate 11, and the axis of the first guide roller 111 is perpendicular to the surface of the upright plate 11.

[0093] Optionally, Figure 7 This is a top view of the first adhesive application unit of this application. Figure 8 This is a side view of the first adhesive application unit of this application. Figure 9 This is a front view structural diagram of the first adhesive application unit of this application, as shown below. Figure 7 , Figure 8 and Figure 9 As shown, the first gluing unit 13 includes a first mounting frame 131, a guide roller 132, a first anilox roller 133, and a first scraper 134. The first mounting frame 131 is movably arranged relative to the upright plate 11. The guide roller 132, the first anilox roller 133, and the first scraper 134 are connected to the first mounting frame 131. The first anilox roller 133 is used to apply the curing adhesive to the guide roller 132. The first scraper 134 is arranged adjacent to the first anilox roller 133. The guide roller 132 is arranged adjacent to the first guide roller 111. The film 31 passes between the guide roller 132 and the first guide roller 111 to realize the application of the first adhesive layer 41 in each first region. In this embodiment, the first mounting bracket 131 is also provided with a first adhesive groove, and the first anilox roller 133 is at least partially disposed in the first adhesive groove. The first adhesive groove is used to contain liquid curing adhesive. When the first anilox roller 133 rotates, the liquid curing adhesive adheres to the surface of the first anilox roller 133, and at the same time, the first anilox roller 133 coats the liquid curing adhesive onto the guide roller 132. The first scraper 134 is used to scrape the liquid curing adhesive on the surface of the first anilox roller 133 flat.

[0094] Optionally, the axes of the guide roller 132 and the first anilox roller 133 are both perpendicular to the surface of the vertical plate 11, that is, the guide roller 132 and the first guide roller 111 are parallel and opposite to each other.

[0095] Optionally, such as Figure 8 and Figure 9As shown, the first gluing unit 13 also includes a first gluing driver 135, which is used to drive the first mounting frame 131 to move toward or away from the first guide roller 111. The moving direction of the first mounting frame 131 is parallel to the upright plate 11. In this embodiment, the first adhesive application driver 135 is, for example, a double-stroke cylinder. During the first adhesive application, the first adhesive application driver 135 drives the first mounting frame 131 to move a first predetermined distance, for example, 25mm, towards the first guide roller 111. At this time, the guide roller 132 contacts the first area of ​​the film 31. After the first area is coated, the first adhesive application driver 135 drives the first mounting frame 131 to move a second predetermined distance, for example, 5mm, away from the first guide roller 111. At this time, the guide roller 132 leaves the surface of the film 31, i.e., avoids the second area of ​​the film 31. When the next area is coated, the first adhesive application driver 135 drives the first mounting frame 131 to move a second predetermined distance, for example, 5mm, towards the first guide roller 111. At this time, the guide roller 132 contacts the first area of ​​the film 31. This process is repeated to coat multiple areas of the film 31. This application uses a double-stroke cylinder for driving, which can quickly switch between adhesive application and non-adhesive application states, resulting in fast response and high work efficiency.

[0096] Optionally, such as Figure 7 and Figure 9 As shown, the first scraper 134 is slidably connected to the first mounting bracket 131. The first gluing unit 13 also includes a first scraper driver 136, which is connected to the first mounting bracket 131. The first scraper driver 136 is used to drive the first scraper 134 to move towards or away from the first anilox roller 133. In this embodiment, the first scraper driver 136 is, for example, a cylinder or an electric cylinder; the first scraper driver 136 is used to adjust the distance between the first scraper 134 and the first anilox roller 133.

[0097] Optionally, such as Figure 8 As shown, the two ends of the first scraper 134 are connected by the first fixing bracket 137. The first fixing bracket 137 is movable relative to the first mounting bracket 131. The output shaft of the first scraper driver 136 is connected to the first fixing bracket 137.

At this time, the second anilox roller 162 leaves the surface of the film 31, that is, avoids the first area of ​​the film 31. When the next second area is coated, the second adhesive application driver 164 drives the second mounting frame 161 to move a second set distance, for example, 5mm, toward the second guide roller 112. At this time, the second anilox roller 162 contacts the second area of ​​the film 31. This process is repeated to apply adhesive to multiple second areas of the film 31.

[0113] Optionally, the first printing unit 15 further includes a first printing roller driver (not shown), which is connected to the first printing roller 151 and is used to drive the first printing roller 151 to rotate. In this embodiment, the first printing roller driver is, for example, a motor; the first printing roller driver transmits the film 31 by driving the first printing roller 151 to rotate; the higher the driving power of the first printing roller driver, the faster the rotation speed of the first printing roller 151 and the greater the tension of the film 31; the lower the driving power of the first printing roller driver, the slower the rotation speed of the first printing roller 151 and the smaller the tension of the film 31.

[0114] Optionally, the second printing unit 17 further includes a second printing roller driver (not shown), which is connected to the second printing roller 171 and is used to drive the second printing roller 171 to rotate. In this embodiment, the second printing roller driver is, for example, a motor; the second printing roller driver conveys the film 31 by driving the second printing roller 171 to rotate; the higher the driving power of the second printing roller driver, the faster the rotation speed of the second printing roller 171 and the greater the tension of the film 31; the lower the driving power of the second printing roller driver, the slower the rotation speed of the second printing roller 171 and the smaller the tension of the film 31.

[0115] Optionally, such as Figure 1 As shown, the film imprinting system also includes a first detection device located between the first printing roller and the second printing roller. The first detection device is electrically connected to the first printing roller driver and the second printing roller driver respectively. The first detection device is configured to detect the relative position of the first pattern 411 and the second pattern 421, and adjust the driving power of the first printing roller driver and / or the second printing roller driver according to the detection result.

[0116] When the second pattern 421 deviates forward from the first pattern 411 along the conveying direction of the film 31, the control system adjusts the driving power of the first plate roller driver and / or the second plate roller driver to reduce the tension of the film 31 between the first plate roller 151 and the second plate roller 171.

[0118] The first detection device of this application can detect the relative arrangement of the first pattern 411 and the second pattern 421 in real time, and correct the film 31 according to the detection results to ensure the continuity of the splicing of the first pattern 411 and the second pattern 421. Since the overlapping area 42a has no impact on the visual effect of the entire product, it is not necessary to make the first pattern 411 and the second pattern 421 precisely seamlessly spliced. The two sides of the second adhesive layer 42 only need to overlap with the edges of the two adjacent first adhesive layers 41. Therefore, the correction accuracy requirement of the equipment is low, and it is sufficient to ensure the continuity of the first pattern 411 and the second pattern 421. The production process is more flexible and simpler.

[0125] When the second pattern 421 deviates to the right by a second distance from the first pattern 411 along the width direction of the film 31, the translation actuator 176 drives the sliding seat 175 to move to the left by a second distance. In this embodiment, the translation actuator 176 is fixed on the upright plate 11. The translation actuator 176 is, for example, an electric cylinder.
