[0002] Roll-to-roll exposure equipment is an advanced production equipment used in the electronics manufacturing industry, mainly for the exposure processing of roll materials such as flexible printed circuit boards (FPCs) and touch screens.
[0003] Roll-to-roll exposure equipment mainly consists of a feeding device, a receiving device, and an exposure device. During operation, the feeding device unrolls the roll material and conveys it into the exposure area via a conveyor. The exposure device exposes the roll material according to preset patterns and parameters. After exposure, the receiving device retracts the exposed roll material, completing the entire roll-to-roll exposure process.
[0004] However, existing feeding and taking-up devices are limited by their precision, and the actual position of the roll material is prone to some error when feeding and taking-up the roll material. In this case, when the roll material is continuously exposed, the products exposed on the roll material are prone to overlap, resulting in poor exposure effect of the products on the roll material, or there is a certain gap between adjacent products on the roll material, resulting in low utilization of the roll material.

[0048] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0049] This application discloses a roll-to-roll seamless splicing device.
[0050] A roll-to-roll seamless splicing device includes an exposure assembly 1, a positioning assembly 2, and a clamping assembly 3. The exposure assembly 1 includes a light source and a mask, the mask being movable within the exposure area; the positioning assembly 2 includes multiple monitoring units; and the clamping assembly 3 is provided in pairs, with the pair of clamping assemblies 3 distributed at both ends of the exposure assembly 1.
[0051] During the exposure process of the roll material, the roll material is unwound and wound up by the unwinding and winding devices. The roll material passes through the exposure area of the photomask during the unwinding and winding process. When the roll material needs to be exposed, the clamping assembly 3 clamps and fixes the roll material, reducing the possibility of exposure deviation caused by shaking during the exposure process.
[0052] In this embodiment, the exposure surface is rectangular, with the top of the rectangle being the upper edge line 5 of the product and the bottom of the rectangle being the lower edge line 6 of the product.
[0053] When producing the first product on the roll material, multiple positioning components 2 grasp the edge-finding target points on the mask, averaging the position of each edge-finding target point relative to the top and bottom edges of the product to ensure consistent vertical spacing. The mask is then moved to the corresponding position, completing the alignment and allowing for exposure. After the first exposure, the roll material is moved by the feeding and taking-up devices, the distance of which is the product step distance. This aligns the dry film color-changing target points of the first product with the seamless splicing target points. Again, the position of each edge-finding target point relative to the top and bottom edges of the product is averaged to ensure consistent vertical spacing, completing the alignment and allowing for exposure. Subsequent products are aligned and spliced in the same manner. This process ensures that the error between two adjacent products is within 20µm, achieving seamless splicing.
[0054] The dry film color-changing target points include a first dry film color-changing target point 7 and a second dry film color-changing target point 8. The seamless splicing target points include a first seamless splicing target point 9 and a second seamless splicing target point 10. When the dry film color-changing target points and seamless splicing target points correspond, the first dry film color-changing target point 7 corresponds to the first seamless splicing target point 9, and the second dry film color-changing target point 8 corresponds to the second seamless splicing target point 10. The distance between the first dry film color-changing target point 7 and the first seamless splicing target point 9 is the product step distance.
[0055] The mask includes a first mask 15 and a second mask 16, which are parallel to each other. The first mask 15 moves via a first power source, and the second mask 16 moves via a second power source. The roll material is placed between the first mask 15 and the second mask 16.
[0056] The roll material is positioned between the first mask 15 and the second mask 16, both of which are horizontally arranged, with the first mask 15 positioned above the second mask 16. The roll material is exposed on both sides through the first mask 15 and the second mask 16. The positions of the first mask 15 and the second mask 16 in the exposure area are adjusted by a first power source and a second power source, respectively, to align with the edge-finding target points.
[0057] In this embodiment of the application, the edge-finding target is located at the corner of the exposure surface, and the edge-finding target includes a first edge-finding target 11, a second edge-finding target 12, a third edge-finding target 13 and a fourth edge-finding target 14.
[0058] The monitoring unit is installed above the first mask plate 15. In this embodiment, the monitoring unit includes a first monitoring unit 21, a second monitoring unit 22, a third monitoring unit 23, and a fourth monitoring unit 24, all of which are CCD cameras. The first monitoring unit 21, the second monitoring unit 22, the third monitoring unit 23, and the fourth monitoring unit 24 are at the same horizontal height and can all move within the same horizontal plane.
[0059] The clamping assembly 3 includes a base frame 31 and a pressure block 32. The roll material is placed between the base frame 31 and the pressure block 32, and the pressure block 32 can intermittently press the roll material onto the base frame 31. In this embodiment, the pressure block 32 and the base frame 31 are connected by a cylinder. The overall length of the cylinder is adjusted to move the pressure block 32 closer to or further away from the base frame 31. When it is necessary to clamp the roll material, the cylinder moves the pressure block 32 closer to the base frame 31, so that the pressure block 32 presses the roll material onto the base frame 31, thereby fixing the roll material and reducing the possibility of the roll material moving and affecting the alignment accuracy when the monitoring unit is aligned.
[0060] The first power source includes a first load-bearing plate 17, a second load-bearing plate 18, and a third load-bearing plate 19. The second load-bearing plate 18 is positioned above the first load-bearing plate 17 and can move horizontally relative to the first load-bearing plate 17. The third load-bearing plate 19 is positioned above the second load-bearing plate 18 via a lifting frame 181 and can move vertically relative to the second load-bearing plate 18. A first mask plate 15 is positioned on the third load-bearing plate 19. The first mask plate 15 can move vertically relative to the third load-bearing plate 19.
[0061] The first load-bearing plate 17 is fixedly installed in the working area. Both the first load-bearing plate 17 and the second load-bearing plate 18 are horizontally arranged. The second load-bearing plate 18 and the first load-bearing plate 17 are connected by multiple linear displacement mechanisms, such as rodless cylinders and / or lead screw modules. In the embodiments of this application, rodless cylinders and lead screw modules are used in combination.
[0062] The third load-bearing plate 19 is horizontally positioned above the second load-bearing plate 18. Multiple lifting frames 181 are arranged around the third load-bearing plate 19. The third load-bearing plate 19 and the second load-bearing plate 18 are connected via the lifting frames 181. In this embodiment, there are four lifting frames 181, which are vertically arranged screw modules. The third load-bearing plate 19 moves precisely in the vertical direction via the four lifting frames 181, and is supported by the four lifting frames 181. The second load-bearing plate 18 causes the third load-bearing plate 19 to move horizontally via the lifting frames 181.
[0063] Four monitoring units are circumferentially mounted above the third load-bearing plate 19. The monitoring units are also connected by multiple linear displacement mechanisms, such as rodless cylinders and / or lead screw modules. In this embodiment, rodless cylinders and lead screw modules are used in combination.
[0064] The first mask plate 15 is horizontally placed below the third load-bearing plate 19. The first mask plate 15 and the third load-bearing plate 19 are connected by multiple cylinders. The position of the first mask plate 15 in the vertical direction is adjusted by adjusting the overall length of the cylinders.
[0065] The second power source includes a fourth load-bearing plate 20, which is placed on the second load-bearing plate 18 and can move relative to the second load-bearing plate 18 in the horizontal direction. The second load-bearing plate 18 and the fourth load-bearing plate 20 are connected by multiple linear displacement mechanisms, such as rodless cylinders and / or lead screw modules. In the embodiments of this application, rodless cylinders and lead screw modules are used in combination.
[0066] After the second load-bearing plate 18 drives the fourth load-bearing plate 20 to move in the horizontal direction, the fourth load-bearing plate 20 is further fine-tuned through a linear displacement mechanism.
[0067] The second load-bearing plate 18 is provided with guide support assemblies 4, and there is a pair of guide support assemblies 4, which are respectively located at both ends of the second load-bearing plate 18. The guide support assembly 4 includes a mounting frame 42 and a guide roller 41, wherein the guide roller 41 is disposed on the mounting frame 42, and the guide roller 41 is rotatably engaged with the mounting frame 42. The distance between the mounting frame 42 and the roll material is adjustable. The mounting frame 42 and the second load-bearing plate 18 are connected by a cylinder to facilitate fine adjustment of the distance between the guide roller 41 and the roll material, so that the guide roller 41 guides and supports the roll material.
[0068] The implementation principle of a roll-to-roll seamless splicing device according to an embodiment of this application is as follows: In the roll-to-roll seamless splicing device, the roll material is unwound and rewound through an unloading device and a rewinding device, passing through the exposure area of the mask during the unloading and rewinding process. When producing the first product, the positioning component 2 grasps the edge-finding target point on the mask, adjusts it to be evenly positioned with consistent vertical spacing along the upper and lower edges of the product, and then completes the alignment and exposure. After the first exposure, the unloading device and the rewinding device move the roll material by the product step distance, so that the dry film color-changing target point of the first product corresponds to the seamless splicing target point. Then, the edge-finding target point is adjusted again to be evenly positioned with consistent vertical spacing along the upper and lower edges of the product, and then completes the alignment and exposure. Subsequent products are aligned and spliced in the same manner. During this process, the clamping component 3 clamps and fixes the roll material, reducing the possibility of exposure deviation caused by shaking of the roll material during exposure. Simultaneously, the first power source and the second power source adjust the positions of the first mask 15 and the second mask 16 in the exposure area, respectively, to facilitate the adjustment of the position of the edge-finding target point. During the alignment of the monitoring unit, the roll material is clamped and fixed to prevent movement from affecting the alignment accuracy. The guide support assembly 4 provides guidance and support for the roll material. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
