[0076] Base 100;

[0077] The unwinding mechanism and the winding mechanism are respectively arranged on opposite sides of the base 100, the unwinding mechanism is used for unwinding the roll material 200 and conveying the roll material 200 to the winding mechanism;

[0078] The first fixing device and the second fixing device are arranged on the base 100, and the first fixing device and the second fixing device are arranged in the conveying direction of the roll material 200, the first fixing device is used for fixing the roll material 200 from below, and the second fixing device is used for fixing the roll material 200 from above;

[0080] The lower exposure device 600 is arranged on the base 100 and below the second fixing device, and the lower exposure device 600 is used for front alignment exposure of the roll material 200 from bottom to top and back alignment exposure of the corresponding exposure area, so as to sequentially perform front alignment exposure and back alignment exposure in one roll-to-roll operation.

[0081] Reference Figure 1 And Figure 2 The unwinding mechanism includes a feeding mechanism and two first driving wheels, the feeding mechanism is used for unwinding the roll material 200, and the two first driving wheels are used for receiving the roll material 200 and conveying the roll material 200 to the winding mechanism after rotation; the winding mechanism includes two second driving wheels and a collecting mechanism, the two second driving wheels and the two first driving wheels are correspondingly arranged on opposite sides of the base 100, and the two second driving wheels are used for receiving the roll material 200 conveyed by the two first driving wheels and conveying the roll material 200 to the collecting mechanism.

[0082] It should be noted that Figure 1 And Figure 2 Only the structures of the two first driving wheels and the two second driving wheels are shown in the above two embodiments, and the specific structures of the feeding mechanism and the collecting mechanism are prior art known to those skilled in the art, which will not be described here.

[0083] It can be understood that the first fixing device and the second fixing device are arranged in the conveying direction of the roll material 200, the first fixing device is used for fixing the roll material 200 from below, and the second fixing device is used for fixing the roll material 200 from above, the upper exposure device 500 is located above the first fixing device, and the lower exposure device 600 is located below the second fixing device, which is equivalent to that the positions of the first fixing device and the upper exposure device 500 are front alignment exposure stations, and the positions of the second fixing device and the lower exposure device 600 are back alignment exposure stations.

[0084] The overall exposure working process is as follows:

[0085] The process that the coiled material 200 is conveyed to the winding mechanism by the unwinding mechanism is called a single roll-to-roll stroke. The coiled material 200 firstly passes through a front surface alignment exposure work station corresponding to the first fixing device and the upper exposure device 500, is fixed from below by the first fixing device, and then is exposed from top to bottom by the upper exposure device 500. After exposure, the coiled material 200 continues to move to a back surface alignment exposure work station corresponding to the second fixing device and the lower exposure device 600, is fixed from above by the second fixing device, and then is exposed from bottom to top by the lower exposure device 600, so that the front surface alignment exposure and the back surface alignment exposure are sequentially performed in a single roll-to-roll stroke.

[0086] The front surface alignment exposure work station and the back surface alignment exposure work station are arranged in the utility model, no turning operation is needed, the overall exposure efficiency is high, on the one hand, the problem of unnecessary loss in the turning operation process of the traditional roll-to-roll exposure machine can be solved; on the other hand, the coiled material 200 is fixed by the first fixing device when the front surface alignment exposure is performed, the coiled material 200 is fixed by the second fixing device when the back surface alignment exposure is performed, and the coiled material 200 is fixed by two exposure surfaces, so that the image quality problem caused by the fact that the coiled material 200 is not flat when the upper and lower exposure is simultaneously performed in the existing new roll-to-roll exposure machine can be solved.

[0087] According to the double-sided roll-to-roll direct writing exposure machine, the coiled material 200 is fixed from below by the first fixing device after moving to above the first fixing device by the unwinding mechanism and the winding mechanism, then the coiled material 200 is exposed from top to bottom by the upper exposure device 500, then the coiled material 200 continues to move to below the second fixing device, the coiled material 200 is fixed from above by the second fixing device, then the coiled material 200 is exposed from bottom to top by the lower exposure device 600, so that the front surface alignment exposure and the back surface alignment exposure can be sequentially performed in a single roll-to-roll stroke, the overall exposure efficiency is high, the problem of unnecessary loss in the turning operation process of the traditional roll-to-roll exposure machine can be solved, and the image quality problem caused by the fact that the coiled material 200 is not flat when the upper and lower exposure is simultaneously performed in the existing new roll-to-roll exposure machine can be solved.

[0088] In some embodiments of the utility model, referring to Figures 1 to 4 The first fixing device comprises a first adsorption platform 310 and two first pressing plate mechanisms 320.

[0089] The first adsorption platform 310 is arranged on the base 100, and the first adsorption platform 310 and the second fixing device are arranged along the conveying direction of the roll material 200, and the first adsorption platform 310 is used to adsorb the roll material 200 from below.

[0090] Two first pressing plate mechanisms 320 are arranged at two ends of the first adsorption platform 310 respectively, and the two first pressing plate mechanisms 320 are arranged along the conveying direction of the roll material 200, and the distance between the two first pressing plate mechanisms 320 is greater than the adsorption width of the first adsorption platform 310, and the two first pressing plate mechanisms 320 are used to press the roll material 200 on the first adsorption platform 310 from above.

[0091] The first adsorption platform 310 can adopt vacuum adsorption, which can more effectively ensure the flatness of the roll material 200 during exposure.

[0092] The first pressing plate mechanism 320 can adopt a plate-shaped mechanism or a wheel-shaped structure, as long as the roll material 200 can be pressed on the first adsorption platform 310, and it cannot be regarded as a limitation of the utility model.

[0093] It can be understood that, in the process of moving the roll material 200 by the unwinding mechanism and the winding mechanism, there is a gap between the roll material 200 and the first adsorption platform 310, otherwise the roll material 200 and the first adsorption platform 310 will rub during the movement of the roll material 200, so after the roll material 200 reaches the exposure position, the roll material 200 needs to be pressed on the first adsorption platform 310 by the first pressing plate mechanism 320, and then the first adsorption platform 310 starts to adsorb, and then the upper exposure device 500 exposes the roll material 200 from top to bottom.

[0094] It should be noted that the first adsorption platform 310 can also directly adsorb the roll material 200 from below, as long as it can adsorb the roll material 200, and it cannot be regarded as a limitation of the utility model. However, after the roll material 200 is pressed on the first adsorption platform 310 by the first pressing plate mechanism 320, the first adsorption platform 310 starts to adsorb, which can further improve the flatness of the roll material 200 during exposure and improve the final image quality.

[0095] In addition, the distance between the two first pressing plate mechanisms 320 is greater than the adsorption width of the first adsorption platform 310, in order to prevent the first pressing plate mechanism 320 from knocking on the first adsorption platform 310, causing damage to the roll material 200, and hindering the exposure process, and the distance between the two first pressing plate mechanisms 320 is greater than the adsorption width of the first adsorption platform 310, which can press the roll material 200 more comfortably on the first adsorption platform 310. In some embodiments, the centers of the two first pressing plate mechanisms 320 are the center of the first adsorption platform 310, and the symmetrical structure can press the roll material 200 more comfortably on the first adsorption platform 310.

[0096] In some embodiments of the present application, referring to Figure 3 , the first adsorption platform 310 comprises a first support 311, a first lifting mechanism 312 and a first adsorption mechanism 313.

[0097] The first support 311 is arranged on the base 100, and the first support 311 and the second fixing device are arranged in the conveying direction of the roll material 200;

[0098] The first lifting mechanism 312 is fixedly connected at the bottom to the upper surface of the first support 311, and is movable at the top in the direction away from or close to the first support 311;

[0099] The first adsorption mechanism 313 is fixedly connected at the bottom to the top of the first lifting mechanism 312, and the top is used to adsorb the roll material 200 from below.

[0100] It can be understood that the first support 311 is used to raise the first adsorption mechanism 313, so as to adapt to the distance between the roll material 200 and the first adsorption mechanism 313. The first lifting mechanism 312 is used to adapt to roll materials 200 of different thicknesses, and by adjusting the height of the first lifting mechanism 312, the plane of the roll material 200 to be exposed is within the exposure depth of field range.

[0101] It should be noted that the specific structure of the first lifting mechanism 312 is not limited here, as long as the height of the first adsorption mechanism 313 can be controlled.

[0102] In some embodiments of the present application, referring to Figure 4 and Figure 5 Each first pressing plate mechanism 320 comprises a first pressing plate assembly mounting plate 321, a first guide rail mounting plate 322, a first lifting assembly 323, a first connecting mounting plate 324 and a first pressing wheel 325.

[0103] The first pressing plate assembly mounting plate 321 is connected at one end of the first surface to one end of the first adsorption platform 310 in the conveying direction of the roll material 200, and the first pressing plate assembly mounting plate 321 is located on one side of the roll material 200;

[0104] The first guide rail mounting plate 322 is connected to the second surface of the first pressing plate assembly mounting plate 321, and the first guide rail mounting plate 322 is perpendicular to the second surface of the first pressing plate assembly mounting plate 321 and the upper surface of the first adsorption platform 310;

[0105] The first lifting assembly 323 is arranged on the surface of the first guide rail mounting plate 322 close to the roll material 200, and the first lifting assembly 323 is movable in the direction perpendicular to the roll material 200;

[0108] It can be understood that the first pressing plate assembly mounting plate 321 is used to raise the height of the first pressing wheel 325, so that the first pressing wheel 325 is higher than the roll material 200. The first guide rail mounting plate 322, the first lifting assembly 323 and the first connecting mounting plate 324 are used to further adjust the height of the first pressing wheel 325, so that the first pressing wheel 325 can press the roll material 200 on the first adsorption mechanism 313, and can also adapt to roll materials 200 of different thicknesses.

[0109] It should be noted that the specific structure of the first lifting assembly 323 is not limited here, as long as the height of the first pressing wheel 325 can be controlled.

[0110] In some embodiments, the distance between the two first pressing wheels 325 is greater than the adsorption width of the first adsorption mechanism 313, which can prevent the first pressing wheel 325 from knocking on the first adsorption mechanism 313, causing damage to the roll material 200, and hindering the progress of the exposure process, and the distance between the two first pressing wheels 325 is greater than the adsorption width of the first adsorption mechanism 313, which can press the roll material 200 more comfortably on the first adsorption mechanism 313.

[0111] In some embodiments, the centers of the two first pressing wheels 325 are the center of the first adsorption mechanism 313, and the symmetrical structure can press the roll material 200 more comfortably on the first adsorption mechanism 313.

[0112] In some embodiments of the utility model, with reference to Figures 1 to 4 , the second fixing device includes a second adsorption platform 410 and two second pressing plate mechanisms 420.

[0113] The second adsorption platform 410 is arranged on the base 100, and the second adsorption platform 410 and the first fixing device are arranged in the conveying direction of the roll material 200, and the second adsorption platform 410 is used to adsorb the roll material 200 from above the roll material 200;

[0114] The two second pressing plate mechanisms 420 are respectively arranged at both ends of the second adsorption platform 410, and the two second pressing plate mechanisms 420 are arranged in the conveying direction of the roll material 200, and the distance between the two second pressing plate mechanisms 420 is greater than the adsorption width of the second adsorption platform 410, and the two second pressing plate mechanisms 420 are used to press the roll material 200 on the second adsorption platform 410 from below.

[0115] The second adsorption platform 410 can adopt vacuum adsorption, which can more effectively ensure the flatness of the roll material 200 during exposure.

[0116] The second pressing plate mechanism 420 can adopt a plate-shaped mechanism or a wheel-shaped structure, as long as it can press the roll material 200 on the second adsorption platform 410, and cannot be regarded as a limitation of the utility model.

[0117] It can be understood that, during the movement of the unwinding mechanism and the winding mechanism to the roll material 200, there is a slight gap between the roll material 200 and the second adsorption platform 410, otherwise the roll material 200 and the second adsorption platform 410 will rub during the movement of the roll material 200, so after the roll material 200 reaches the exposure position, the roll material 200 needs to be pressed on the second adsorption platform 410 by the second pressing plate mechanism 420, then the second adsorption platform 410 starts to adsorb, and then the lower exposure device 600 exposes the roll material 200 from bottom to top.

[0118] It should be noted that the second adsorption platform 410 can also directly adsorb the roll material 200 from above, as long as it can adsorb the roll material 200, and cannot be regarded as a limitation of the utility model. However, after the roll material 200 is pressed on the second adsorption platform 410 by the second pressing plate mechanism 420, the second adsorption platform 410 starts to adsorb, which can further improve the flatness of the roll material 200 during exposure and improve the final image quality.

[0119] In addition, the distance between the two second pressing plate mechanisms 420 is greater than the adsorption width of the second adsorption platform 410, in order to prevent the second pressing plate mechanism 420 from knocking on the second adsorption platform 410, causing damage to the roll material 200, and hindering the exposure process, and the distance between the two second pressing plate mechanisms 420 is greater than the adsorption width of the second adsorption platform 410, which can press the roll material 200 more comfortably on the second adsorption platform 410. In some embodiments, the centers of the two second pressing plate mechanisms 420 are the center of the second adsorption platform 410, and the symmetrical structure can press the roll material 200 more comfortably on the second adsorption platform 410.

[0120] In some embodiments of the utility model, referring to Figures 1 to 3 , the second adsorption platform 410 includes a vertical support plate 411, a second support 412 and a second adsorption mechanism 413.

[0122] a second support 412, a side of which is connected with a surface of the vertical support plate 411 facing the roll material 200, and the second support 412 is located above the roll material 200;

[0123] a second suction mechanism 413, a top of which is fixedly connected with a bottom of the second support 412, and the bottom is used for sucking the roll material 200 from above.

[0124] It can be understood that the vertical support plate 411 is used for supporting and fixing the second support 412 and the second suction mechanism 413, and leaving installation space for the lower exposure device 600. The vertical support plate 411 comprises a vertical installation stand and reinforcing rib plates connected at opposite ends of the installation stand, both of which are perpendicular to the installation stand and the base 100, and the reinforcing rib plates are used for improving the stability of the entire vertical support plate 411. The specific structure and size of the reinforcing rib plates can be selected according to actual conditions, and are not specifically limited here.

[0125] The second support 412 is used for installing the downward second suction mechanism 413.

[0126] In some embodiments of the present application, referring to Figure 4 and Figure 5 each second pressing plate mechanism 420 comprises a second pressing plate assembly mounting plate, a second guide rail mounting plate, a second lifting assembly, a second connecting mounting plate and a second pressing roller.

[0127] The second pressing plate assembly mounting plate is connected at one end of a first surface thereof with one end of the second suction platform 410 above the roll material 200 in the conveying direction of the roll material 200, and the second pressing plate assembly mounting plate is located on one side of the roll material 200;

[0131] One end of the second pressing roller is connected with a second surface of the second connecting mounting plate, and the other end extends to the other side of the roll material 200, and the second pressing roller is located below the roll material 200.

[0132] It can be understood that the second pressing plate assembly mounting plate is used to adjust the height of the second pressing wheel so that the second pressing wheel is lower than the roll 200. The second guide rail mounting plate, the second lifting assembly and the second connecting mounting plate are used to further adjust the height of the second pressing wheel so that the second pressing wheel can press the roll 200 on the second adsorption mechanism 413 and can also adapt to the roll 200 of different thicknesses.

[0133] It should be noted that the specific structure of the second lifting assembly is not limited here as long as the height of the second pressing wheel can be controlled.

[0134] In some embodiments, the distance between the two second pressing wheels is greater than the adsorption width of the second adsorption mechanism 413, which can prevent the second pressing wheel from knocking on the second adsorption mechanism 413, causing damage to the roll 200 and hindering the progress of the exposure process, and the distance between the two second pressing wheels is greater than the adsorption width of the second adsorption mechanism 413. The roll 200 can be more comfortably pressed on the second adsorption mechanism 413.

[0141] As Figure 3 shown, the first support 311 includes two supports and a placing plate, the two supports are arranged opposite to each other along the conveying direction of the roll material 200, and the two supports are perpendicular to the base 100; the placing plate is arranged on the two supports, and the first lifting mechanism 312 and the first adsorption mechanism 313 are arranged above the placing plate, so that the first guide rail mechanism 101 can be arranged below the first fixing device.

[0142] As Figure 6 shown, the first guide rail mechanism 101 includes two parallel first guide rail strips, and the lower surface of the first cross plate 510 is slidably connected with the two first guide rail strips, and the first cross plate 510 can slide in the direction close to or away from the roll material 200.

[0143] In some embodiments, two reinforcing rib plates are arranged on the two ends of the first cross plate 510 along the axis direction of the two first guide rail strips, and the two reinforcing rib plates are perpendicular to the first cross plate 510, one side of each reinforcing rib plate is connected with the upper surface of the first cross plate 510, and the adjacent side is connected with the first support plate 520, and the two reinforcing rib plates are used for enhancing the stability between the first cross plate 510 and the first support plate 520.

[0144] In some embodiments, two reinforcing rib plates are arranged on the two ends of the second cross plate 530 along the axis direction of the two first guide rail strips, and the two reinforcing rib plates are perpendicular to the second cross plate 530, one side of each reinforcing rib plate is connected with the lower surface of the second cross plate 530, and the adjacent side is connected with the first support plate 520, and the two reinforcing rib plates are used for enhancing the stability between the second cross plate 530 and the first support plate 520.

[0145] The upper exposure assembly 540 includes a plurality of exposure heads and two alignment cameras, the plurality of exposure heads are arranged on one end of the second cross plate 530 away from the first support plate 520, the two alignment cameras are arranged opposite to each other on the two ends of the second cross plate 530 and are located on the two sides of the area where the plurality of exposure heads are located, and the connecting line direction of the two alignment cameras is the same as the conveying direction of the roll material 200.

[0146] The exposure process is as follows:

[0147] The first cross plate 510 slides to below the first support 311, so that the plurality of exposure heads are located directly above one side of the roll material 200, alignment is performed through the two alignment cameras, and after the alignment is completed, exposure is started, and during the exposure process, the first cross plate 510 moves to the other side of the roll material 200, so that the plurality of exposure heads complete the exposure on the entire exposure area of the roll material 200.

The length of the first guide rail mechanism 101 is at least twice the width of the roll 200. In order for multiple exposure heads to expose the entire exposure area of ​​the roll 200, the width of the second horizontal plate 530 (i.e., the distance from the end of the second horizontal plate 530 away from the first support plate 520 to the first support plate 520) must be at least greater than the width of the roll 200. In order to reduce the overall volume of the upper exposure device 500, the length of the first guide rail mechanism 101 being at least twice the width of the roll 200 allows multiple exposure heads to expose the entire exposure area of ​​the roll 200.

[0149] It should be noted that, considering the stability between the first horizontal plate 510, the first support plate 520, and the second horizontal plate 530, as well as low material costs, in this embodiment, the width and thickness of the first horizontal plate 510 and the second horizontal plate 530 are the same.

[0150] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 7 The base 100 is also provided with a second guide rail mechanism 102, which passes through the lower part of the second fixing device. The axis of the second guide rail mechanism 102 is perpendicular to the conveying direction of the roll material 200. The lower exposure device 600 includes a third horizontal plate 610, a second support plate 620, a second lifting mechanism 630, a connecting plate 640, a fourth horizontal plate 650, and a lower exposure assembly 660.

However, the present utility model is not limited to the above embodiments.
