Description

Technical Field

[0001] This invention relates to the field of roll-to-roll exposure technology, specifically a roll-to-roll exposure apparatus and its connecting line loading and unloading method. Background Technology

[0002] Traditional double-sided exposure machines typically use film transfer for exposing double-sided circuit boards. Before exposure, film containing the pattern to be transferred needs to be prepared. Then, the film with the patterns on both sides is fixed onto the upper and lower glass plates respectively. Next, the circuit board with the pattern to be transferred is sandwiched between the upper and lower glass plates, and exposure is performed using a blue-violet high-brightness light source to transfer the circuit pattern onto the circuit board, completing the double-sided exposure. This process is cumbersome, and the expansion, contraction, and misalignment of the patterns on both sides of the circuit board cannot be intelligently controlled. The double-sided glass plates are pressed tightly together, and residues remain on the glass after each exposure. If these residues are not cleaned in time, the exposure quality will deteriorate. Cleaning the glass residues requires stopping the machine, which in turn reduces the efficiency of the exposure machine.

[0003] Laser direct-write exposure machines typically use single-sided exposure. One side of the circuit board is exposed first, then flipped over to expose the other side, completing the double-sided exposure. However, this process is cumbersome, lacking intelligent control over the expansion and contraction and misalignment of the patterns on both sides of the circuit board. This not only increases the exposure steps but also affects exposure accuracy due to alignment issues, thus impacting the final exposure effect. This makes it unsuitable for mass production, resulting in low output.

[0004] For some double-sided simultaneous exposure machines, the upper and lower exposure lenses are on different axes, which causes the upper and lower lens sets to move asynchronously and the alignment accuracy to be low. This alignment accuracy problem will also affect the exposure accuracy, thus affecting the final exposure effect. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the first objective of this invention is to provide a roll-to-roll exposure apparatus that ensures the flatness of the incoming material, reduces the probability of roll misalignment and shrinkage, guarantees both alignment and exposure accuracy, and increases the exposure rate, thereby improving production capacity. The second objective of this invention is to provide a roll-to-roll exposure line loading and unloading method. This method, applied to the aforementioned roll-to-roll exposure apparatus, also has the advantages of ensuring the flatness of the incoming material, reducing the probability of roll misalignment and shrinkage, guaranteeing both alignment and exposure accuracy, and increasing the exposure rate.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figs. 1-2 As shown, a roll-to-roll exposure apparatus is used to expose a roll of material 1. It includes an unwinder 10 for unwinding the roll of material 1, an exposure section 20 for exposing the roll of material 1, and a rewinder 40 for rewinding the exposed roll of material 1. The exposure section 20 is located between the unwinder 10 and the rewinder 40. To ensure the flatness of the roll of material 1 and reduce the probability of its expansion, contraction, and deviation, the exposure section 20 includes a pressing, flattening, and correction device 201, a second pressing device 202, and a double-sided exposure machine 205. The pressing, flattening, and correction device 201 and the second pressing device 202 are respectively disposed near both ends of the exposure section 20 to press the roll of material 1 to be exposed. The roll of material 1 passes through the double-sided exposure machine 205 for double-sided exposure.

[0030] To support the roll 1 before exposure and prevent it from bending, the exposure unit 20 is also equipped with a support abacus 206, which is located below the roll 1. The support abacus 206 is movable; it can be equipped with pulleys and rails or sliders and rails at its bottom. This allows the support abacus 206 to be moved to other positions during the exposure process of the double-sided exposure machine 205, preventing the roll 1 from obstructing the view. The double-sided exposure machine 205 then exposes the unexposed areas, ensuring optimal exposure results.

[0031] In order to further compact and flatten the roll material 1, the exposure part 20 is provided with a compacting device three 203 and a compacting device four 204, both of which are located between the compacting and flattening and deviation rectifying device 201 and the compacting device two 202. The compacting device three 203 and the compacting device four 204 are respectively located on both sides of the roll material 1 in the exposure state, compacting the roll material 1 on both sides to avoid the roll material 1 from tilting or deviating, thereby ensuring the exposure effect. Further, in order to avoid damage to the roll material 1 during the compacting process and to avoid indentation, the compacting surfaces of the compacting and flattening and deviation rectifying device 201, the compacting device two 202, the compacting device three 203 and the compacting device four 204 are all flat and are arranged to be in close contact with the surface of the roll material 1. The width of the compacting surfaces of the compacting and flattening and deviation rectifying device 201, the compacting device two 202, the compacting device three 203 and the compacting device four 204 is greater than the width of the roll material 1.

[0032] Specifically, the compacting device two 202, the compacting device three 203 and the compacting device four 204 are structured as follows: a material feeding clamp 20-1 and a clamp bottom plate 20-2 are included, the clamp bottom plate 20-2 is fixedly installed on a clamp fixing seat 20-3, the material feeding clamp 20-1 is installed between two lifting slides 20-4, and a slide rail and a slide block are connected between the clamp fixing seat 20-3 and the lifting slides 20-4, the cross section of the lifting slides 20-4 is arranged in an "L" shape, the lifting slides 20-4 are driven by a driving cylinder 20-5 to drive the material feeding clamp 20-1 to move, thereby changing the distance between the material feeding clamp 20-1 and the clamp bottom plate 20-2, and achieving the compacting operation on the roll material 1.

[0033] The compacting and flattening and deviation rectifying device 201 includes the specific structure of the compacting device, achieves the compacting function, and further includes an electric cylinder 20-6 and a motor 20-7 arranged on one side of the material feeding clamp 20-1 and the clamp bottom plate 20-2, the electric cylinder 20-6 is connected to the bottom of the clamp bottom plate 20-2, and the motor 20-7 is connected to the electric cylinder 20-6, when the roll material 1 is compacted by the material feeding clamp 20-1 and the clamp bottom plate 20-2, the motor 20-7 drives the electric cylinder 20-6 to achieve the tensioning and flattening effect on the roll material 1; and the motor 20-7 and the electric cylinder 20-6 are respectively arranged in pairs, one pair of electric cylinders 20-6 is arranged close to the two ends of the material feeding clamp 20-1 and the clamp bottom plate 20-2, thereby reducing the probability of deviation of the roll material 1.

[0034] In order to facilitate the winding of the exposed roll material 1 and ensure the compactness of the roll material 1 during winding, the exposure device is further provided with a material pulling section 30, which is located between the exposure part 20 and the winding machine 40. The unwinding machine 10, the material pulling section 30 and the winding machine 40 can adopt the corresponding structure in the existing roll-to-roll exposure machine.

[0035] A roll-to-roll exposure line feeding method, comprising the following steps:

[0036] Step 1, the roll material 1 passes through the unwinding machine 1, and the roll material 1 is unwound, and the roll material 1 to be exposed is moved to the exposure position of the double-sided exposure machine 205 through the unwinding machine 1;

[0037] Step 2, the pressing device two 202 presses the roll material 1, and at the same time, the pressing, flattening and deviation correcting device 201 flattens and corrects the deviation;

[0038] Step 3, after the pressing, flattening and deviation correcting device 201 flattens and corrects the deviation, the pressing device three 203 and the pressing device four 204 act at the same time, fix the roll material 1 and perform double-sided exposure on the roll material 1, in order to make the double-sided exposure machine 205 expose the unexposed place, the supporting abacus 206 moves to the area that does not affect the exposure of the roll material 1 during the exposure of the roll material 1, so as to ensure the exposure effect.

[0039] Step 4, the roll material 1 passing through the double-sided exposure machine 205 passes through the pulling section 30, and the roll material 1 is tensioned and flattened to ensure the compactness of the roll material 1 during the winding of the winding machine 40.

[0040] The roll-to-roll exposure device in the embodiment can effectively ensure the flatness of the incoming material, reduce the probability of deviation and expansion of the roll material, ensure the alignment accuracy and ensure the exposure accuracy, by setting the pressing, flattening and deviation correcting device 201 and the pressing device two 202 in the exposure part 20. By setting the movable supporting abacus 206, the roll material can be supported before exposure, further reducing the probability of deviation of the roll material, and the supporting abacus 206 is movably arranged and can be moved during exposure, so that the blocked part is opened, the double-sided exposure machine can expose the unexposed place, and the exposure effect is ensured. By setting the pressing device three 203 and the pressing device four 204, the roll material is further pressed and flattened to ensure the flatness of the incoming material, ensure the alignment accuracy and ensure the exposure accuracy.

[0041] The roll-to-roll exposure line feeding method in the embodiment can effectively reduce the probability of deviation and expansion of the roll material, ensure the alignment accuracy and ensure the exposure accuracy by pressing the pressing device three and the pressing device four at the same time during implementation.
