[0034] Roll-to-roll nanoimprinting is a novel material fabrication technology that can be used to continuously prepare high-quality, high-precision micro / nanostructures.

[0035] Based on this, the present invention provides a double-sided registration and imprinting device, including an unwinding unit, a first imprinting unit, a second imprinting unit, and a rewinding unit connected sequentially through a roll of material.

[0048] To achieve roll-to-roll double-sided registration and printing, this utility model includes a first alignment unit and a second alignment unit in the double-sided registration and printing equipment.

The motion conversion component converts the rotational motion of the driver into the translational motion of the second imprinting unit along the width direction of the roll material.

[0052] The driver includes a motor 14, and the motion conversion assembly includes a lead screw 15 and a lead screw nut 16. The output end of the motor 14 is connected to the lead screw 15 and drives the lead screw 15 to rotate.

[0053] In this embodiment, the first alignment unit is located below the second printing roller 10 in the second printing unit. The second printing roller 10 in the second printing unit is mounted on the upper support plate 17, and a bracket is installed above the upper support plate 17. The second printing roller 10 is fixed on the bracket. The motor 14 is mounted on the lower base plate 18.

[0054] A guide device is provided between the upper support plate 17 and the lower base plate 18. The guide device includes a slider 19 provided at the bottom of the upper support plate 17 and a slide rail 20 provided on the lower base plate 18. The slider 19 and the slide rail 20 are slidably connected.

[0055] In this embodiment, the second alignment unit includes a first tension roller 21, a second tension roller 22, a first tension arm 23, a second tension arm 24, and a third tension arm 25. The tension rollers are used to detect tension, and the tension arms are used to adjust tension. Both the tension rollers and the tension arms are connected to a controller, which receives the detection signal from the tension rollers and controls the tension arms to adjust the tension.

[0056] Specifically, the first tension roller 21 is located between the oven 4 and the first printing roller 6, used to detect the tension of the roll material between the unwinding unit and the first printing roller 6, and transmits the detection signal to the controller; the second tension roller 22 is located between the second gluing device 8 and the second printing assembly, used to detect the tension of the roll material between the first printing roller 6 and the second printing roller 10, and transmits the detection signal to the controller; the first tension arm 23 is located between the unwinding unit and the first gluing device 3, and the controller controls the first tension arm 23 to adjust the tension of the roll material between the unwinding unit and the first printing roller 6 according to the detection signal of the first tension roller 21; the second tension arm 24 is located between the first printing assembly and the second gluing device 8, and the controller controls the second tension arm 24 to adjust the tension of the roll material between the first printing roller 6 and the second printing roller 10 according to the detection signal of the second tension roller 22; the controller controls the third tension arm 25 to adjust the tension of the roll material between the second printing roller 10 and the winding unit according to the tension signal of the winding unit, in coordination with winding alignment.

[0057] The working process of this double-sided pre-pressing device is as follows:

[0058] The roll material is released by the unwinding roller 1, first undergoes preliminary correction by the correction device 2, then is coated with adhesive (UV adhesive) by the first adhesive application device 3, and is first dried in the drying oven 4 to remove moisture from the adhesive. The first pattern, which can be a microlens or micro-nano structure, is imprinted on the first surface (side A) by the first pressure roller 5 and the first printing roller 6. It is then cured by the first curing device 7, and then coated with adhesive by the second adhesive application device 8. The second pattern, which can be a micro-text or micro-nano structure, is imprinted on the second surface (side B) by the second pressure roller 9 and the second printing roller 10. It is then cured by the second curing device 11, completing the double-sided imprinting. Finally, the winding roller 13 winds it up.

[0059] During the embossing process, the tension roller is used to detect tension, and the tension arm is used to adjust the tension.

[0060] The first tension roller 21 is used to detect the tension of the roll material between the unwinding unit and the first plate roller 6, and to adjust the tension through the first tension arm 23, mainly to adjust the tension during the unwinding process.

[0061] The second tension roller 22 is used to detect the tension of the roll material between the first printing roller 6 and the second printing roller 10, and to adjust the tension of the roll material between the first printing roller 6 and the second printing roller 10 through the second tension arm 24.

[0062] The third tension arm 25 adjusts the tension of the roll material between the second roller 10 and the winding unit, mainly to adjust the tension during the winding process and to coordinate with the winding alignment.

[0063] The alignment detection device 26 detects the image or alignment target (such as the first alignment mark 01 and the second alignment mark 02) on the surface of the roll after double-sided imprinting in real time. If the position of the two surfaces after imprinting the micro-nano structure is offset along the width of the roll, the controller controls the motor 14 to rotate accordingly, and drives the upper support plate 17 through the lead screw 15, thereby driving the second printing roller 10 to adjust along the width of the roll so that the pattern or alignment target is completely aligned.

[0064] Specifically, when the pattern on side B is shifted to the left compared to the pattern on side A, the control motor 14 drives the second printing roller 10 to move to the right by a corresponding distance, so that the patterns on side B and side A are aligned; when the pattern on side B is shifted to the right compared to the pattern on side A, the control motor 14 drives the second printing roller 10 to move to the left by a corresponding distance, so that the patterns on side B and side A are aligned.

[0065] If the positions of the two surface micro-nano structures are offset along the roll conveying direction after imprinting, the second tension arm 24 is adjusted to control the tension of the roll between the first printing roller 6 and the second printing roller 10, thereby adjusting the alignment.

[0066] Specifically, when the pattern on side B is offset from the pattern on side A in the direction of roll material transport, the second tension arm 24 is adjusted to reduce the tension of the roll material between the first printing roller 6 and the second printing roller 10, so that the patterns on side B and side A are aligned; when the pattern on side B is offset from the pattern on side A in the direction away from the direction of roll material transport, the second tension arm 24 is adjusted to increase the tension of the roll material between the first printing roller 6 and the second printing roller 10, so that the patterns on side B and side A are aligned.

[0067] This utility model, by setting a first alignment unit and a second alignment unit, performs alignment in the width direction and conveying direction of the roll material, respectively. The structure design is simple, the production speed is fast (1-50m / min), and the alignment accuracy can reach 0.1mm, which is high.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
