In response to the above technical problems, the applicant has retrieved some existing technologies to improve the manufacturing efficiency of the double-sided flexible copper clad laminate, such as a double-sided flexible copper clad laminate manufacturing device and a manufacturing method thereof with patent publication number CN113147147B. Its main technical means is that the double-sided flexible copper clad laminate manufacturing device provided by the present invention has a reasonable structural design, and the substrate film roll, the upper copper foil roll, and the lower copper foil roll are pulled and then hot-pressed into an integrated structure to form a double-sided copper clad laminate with adhesive. Continuous production is carried out using a rolling line, which has high production efficiency, simplifies the operation process, and reduces the equipment procurement cost, thereby reducing the manufacturing cost of the double-sided flexible copper clad laminate. After analysis by the applicant, the disadvantage of this technical solution is that: in the above solution, before the base film roll, the upper copper foil roll and the lower copper foil roll are pulled and hot-pressed into an integrated structure, the base film, the upper copper foil and the lower copper foil rolled up on the base film roll, the upper copper foil roll and the lower copper foil roll may have a winding deviation. In this way, when the base film, the upper copper foil and the lower copper foil are moving, the base film, the upper copper foil and the lower copper foil may deviate from each other, so that the base film, the upper copper foil and the lower copper foil cannot be completely overlapped, and the edges of the copper clad laminate formed by the pressing are not neat and wrinkles may appear on the surface, thereby reducing the quality of the copper clad laminate.

[0012] A method for manufacturing a double-sided flexible copper-clad laminate manufacturing device, the method being applied to the double-sided flexible copper-clad laminate manufacturing device as described above, the method comprising the following steps: Step S1: First, the substrate film roll, upper copper foil roll and lower copper foil roll with the substrate and copper foil rolled up are installed so that the substrate film roll is located between the upper copper foil roll and the lower copper foil roll. Then, the copper foil-substrate-copper foil passes through the cleaning brush, the pressing plate, the auxiliary mechanism, the anti-deflection roll, the guide roll and the hot pressing roll in sequence, and finally is wound up by the winding roll; Step S2: Starting the winding roller to wind up the flexible copper-clad laminate composed of copper foil, substrate, and copper foil. During the winding process, the substrate and the two sets of copper foils will move to the cleaning brush, which cleans the surfaces of the substrate and the two sets of copper foils to make them clean and smooth.

[0013] The beneficial effects of the present invention are: 1. In the present invention, the suction cup, the airbag, the guide plate and the curved portion on the guide plate cooperate with each other in the anti-deflection mechanism, so that when the suction cup moves to the curved portion on the guide plate, the airbag connected to the suction cup slowly expands from being pressed by the two guide plates to its original state. During this process, the airbag absorbs external air, and the suction cup slowly contacts the substrate or copper foil above, so that the suction cup absorbs the substrate or copper foil and drives the substrate or copper foil to move a certain distance. The cooperation of several suction cups makes it difficult for the substrate or copper foil to deviate during the movement, so that the substrate and the two copper foils are in an overlapping state when pressed by the hot pressing roller, thereby ensuring the quality of the pressed copper clad laminate. 2. In the present invention, after the several suction cups at the highest point of the anti-deflection roller suck the substrate or copper foil, the several suction cups will drive the substrate or copper foil to move. During this process, the several suction cups will make a pulling action on the substrate or copper foil, thereby straightening the originally loose or deflected substrate or copper foil, thereby effectively preventing the substrate or copper foil from deflecting. In this way, the substrate and the two copper foils are in an overlapping state when being pressed by the hot pressing roller, thereby ensuring the quality of the pressed copper clad laminate; 3. In the present invention, when the substrate or copper foil moves between the two clamping plates, the two inclined rollers rotate to move the two sides of the substrate or copper foil outward, thereby straightening the substrate or copper foil that has already deviated. This, combined with the subsequent anti-deflection mechanism, can further prevent the substrate or copper foil from deviating during movement, so that the substrate and the two copper foils are in an overlapping state when pressed by the hot pressing rollers, thereby ensuring the quality of the pressed copper clad laminate; 4. In the present invention, during the process of the airbag expanding and returning to its original shape, the suction cup absorbs the air above. When the suction cup slowly comes into contact with the substrate or copper foil, the suction cup will suck down the dust or impurities on the surface of the substrate or copper foil, thereby ensuring that the surface of the substrate or copper foil is clean, so that the laminated copper clad laminate is less likely to have defects. At the same time, when the airbag slowly enters the position between the two guide plates, the airbag is compressed and the suction cup will blow air outward, which can further ensure that the surface of the substrate or copper foil is clean, and further avoid defects inside the laminated copper clad laminate.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0017] like Figure 1-Figure 5 As shown, a double-sided flexible copper clad laminate manufacturing device includes a substrate film roller 1, an upper copper foil roller 2, a lower copper foil roller 3, two sets of guide rollers 10, two sets of hot pressing rollers 11, a winding roller 12, a plurality of brackets 13 and a base 14. The device also includes: Anti-deflection rollers 4: three groups of anti-deflection rollers 4 are mounted on the base 14 through the bracket 13. The three groups of anti-deflection rollers 4 correspond to the base film roller 1, the upper copper foil roller 2 and the lower copper foil roller 3 respectively. Anti-deflection mechanism 5, an anti-deflection mechanism 5 is installed in the anti-deflection roller 4, the anti-deflection mechanism 5 includes a suction cup 51 and an airbag 52, a plurality of through holes are opened on the anti-deflection roller 4, the suction cup 51 is embedded in the through hole, one end of the suction cup 51 is connected to the airbag 52, the airbag 52 is located inside the anti-deflection roller 4, a plurality of groups of guide plates 53 are installed in the anti-deflection roller 4, a plurality of suction cups 51 and airbags 52 on the same cross section are located between the two groups of guide plates 53, a bending portion 531 is provided at the highest point of the guide plate 53, the airbag 52 is in a normal state when it is located at the bending portion 531, and is in a compressed state when it is located at other positions of the guide plate 53, connectors 54 are installed on the two groups of guide plates 53, and fixing rods 55 are provided on the plurality of connectors 54, and both ends of the fixing rod 55 respectively pass through the two ends of the anti-deflection roller 4 and are fixed on the brackets 13 on both sides.
[0018] In one case of this embodiment, a rotating drum 41 is provided at both ends of the anti-skew roller 4, and the rotating drum 41 is connected to an external drive motor, wherein a fixed rod 55 passes through the two rotating drums 41, and the rotating drum 41 drives the anti-skew roller 4 to rotate without being affected by the fixed rod 55.
[0019] In actual application of this embodiment, when the substrate or copper foil moves to the anti-deflection roller 4, the position of the guide plate 53 is different due to the rolling of the anti-deflection roller 4, so that the anti-deflection roller 4 drives the plurality of suction cups 51 to rotate. When the suction cups 51 move to the curved portion 531 on the guide plate 53, the airbags 52 connected to the suction cups 51 are slowly expanded from being pressed by the two guide plates 53 to their original state. During this process, the airbags 52 absorb external air, and at this time, the suction cups 51 slowly come into contact with the substrate or copper foil above. In this way, the suction cup 51 sucks the substrate or copper foil and drives the substrate or copper foil to move a certain distance. Through the cooperation of several suction cups 51, the substrate or copper foil is not easily deflected during the movement, so that the substrate and the two copper foils are in an overlapping state when pressed by the hot pressing roller 11, thereby ensuring the quality of the pressed copper clad laminate; the suction cup 51 slowly enters between the two guide plates 53 during the movement, so that the two guide plates 53 will squeeze the airbag 52, so that the suction cup 51 releases the substrate or copper foil; After the suction cups 51 at the highest point of the anti-deflection roller 4 suck the substrate or copper foil, the suction cups 51 will drive the substrate or copper foil to move. During this process, the suction cups 51 will make a pulling action on the substrate or copper foil, thereby straightening the originally loose or deflected substrate or copper foil, thereby effectively preventing the substrate or copper foil from deflecting. In this way, the substrate and the two copper foils are in an overlapping state when being pressed by the hot pressing roller 11, thereby ensuring the quality of the pressed copper clad laminate; During the process of the airbag 52 expanding and returning to its original shape, the suction cup 51 absorbs the air above. When the suction cup 51 slowly comes into contact with the substrate or copper foil, the suction cup 51 will suck down the dust or impurities on the surface of the substrate or copper foil, thereby ensuring that the surface of the substrate or copper foil is clean, so that it is less likely that there will be defects inside the pressed copper clad laminate; at the same time, when the airbag 52 slowly enters the position between the two guide plates 53, the airbag 52 is compressed and the suction cup 51 will blow air outward, which can further ensure that the surface of the substrate or copper foil is clean, and further avoid defects inside the pressed copper clad laminate; the dust or impurities that enter the airbag 52 will be discharged from the airbag 52 due to their own weight when the suction cup 51 moves to the bottom of the anti-deflection roller 4, and a corresponding collection box can be installed under the anti-deflection roller 4 for collection.
[0020] Furthermore, a guide rail 532 is provided on the inner side of the guide plate 53 , and the two sides of the airbag 52 are fixedly connected with the extrusion plates 521 . The outer side of the extrusion plates 521 is provided with a guide rod 522 , and the guide rod 522 is slidably installed in the guide rail 532 .
[0021] It should be noted that after the airbag 52 is frequently squeezed, the recovery ability of the airbag 52 will gradually weaken, causing the suction cup 51 to be unable to normally absorb the substrate or copper foil. Therefore, a related structure is provided to solve the above problem.
[0022] In actual application of this embodiment, the guide rod 522 moves relative to the guide rail 532 within the guide rail 532. When the guide rod 522 slowly enters the curved portion 531, the guide rod 522 slowly moves outward. The two sets of guide rods 522 move in opposite directions respectively. In this way, the two extrusion plates 521 move outward to pull the airbag 52 to expand and restore to its original state, thereby ensuring that the airbag 52 works normally, and further ensuring that the suction cup 51 can normally absorb the substrate or copper foil, thereby effectively preventing deviation during the movement. When the guide rod 522 moves to a position outside the bent portion 531, the guide rod 522 will slowly move inward and squeeze the airbag 52 through the squeezing plate 521, so that the airbag 52 can be normally compressed, thereby ensuring that the suction cup 51 can be normally inflated; By moving the extrusion plate 521 outward to pull the airbag 52 to expand and restore to its original state, the efficiency of the airbag 52 in restoring its original state can be improved, so that the suction cup 51 can quickly absorb air and hold the substrate or copper foil, ensuring that the suction cup 51 can move the substrate or copper foil for a certain distance; by moving the extrusion plate 521 inward to squeeze the airbag 52, the suction cup 51 can be quickly blown outward, and the force of the outward blowing is increased, thereby improving the efficiency of cleaning dust or impurities.
[0023] like Figure 1 、 Figure 6 and Figure 7 As shown, a plurality of auxiliary mechanisms 6 are mounted on the base 14 via a bracket 13. The plurality of auxiliary mechanisms 6 are located between the substrate film roller 1, the upper copper foil roller 2, the lower copper foil roller 3, and the three groups of anti-deflection rollers 4.

[0024] Furthermore, inclined rollers 63 are installed on opposite sides of the two clamping plates 62 .
[0025] In actual application of this embodiment, when the substrate or copper foil moves between the two clamping plates 62, the two inclined rollers 63 rotate to move the two sides of the substrate or copper foil outward, so that the substrate or copper foil that has been offset can be straightened. This, combined with the subsequent anti-deflection mechanism 5, can further prevent the substrate or copper foil from offsetting during movement, so that the substrate and the two copper foils are in an overlapping state when being pressed by the hot pressing roller 11, thereby ensuring the quality of the pressed copper clad laminate.
[0026] like Figure 1As shown, three pressing plates 7 are installed on the base 14 through the bracket 13. The pressing plates 7 press the substrate or copper foil. The three pressing plates 7 are located between the substrate film roller 1, the upper copper foil roller 2, the lower copper foil roller 3 and several groups of auxiliary mechanisms 6.
[0027] In actual application of this embodiment, the substrate or copper foil with curled or loose edges can be flattened by the pressing plate 7, so that the substrate or copper foil entering the subsequent auxiliary mechanism 6 and the anti-deflection mechanism 5 is in a flat state, further avoiding the substrate or copper foil from being in a deflected state before moving to the hot pressing roller 11, thereby effectively avoiding the uneven edges and surface wrinkles of the pressed copper clad laminate, thereby ensuring the quality of the copper clad laminate.
[0028] like Figure 1 and Figure 7 As shown, two anti-deflection plates 8 are installed on the base 14 through the bracket 13. The anti-deflection plates 8 are located between the guide roller 10 and the hot pressing roller 11. The anti-deflection plates 8 are against the sides of the substrate and the two copper foils.
[0029] In actual application of this embodiment, when the substrate and the two copper foils are moved in front of the two sets of hot pressing rollers 11, the two anti-deflection plates 8 are used to limit the side edges of the substrate and the two copper foils, thereby effectively preventing the substrate and the two copper foils from deflecting before and during hot pressing, thereby further ensuring the quality of the copper clad laminate.
[0030] like Figure 1 and Figure 7 As shown, three groups of cleaning brushes 9 are installed on the base 14 through the bracket 13. There are cleaning brushes 9 at the upper and lower positions of the substrate and the copper foil. The three groups of cleaning brushes 9 are located between the substrate film roller 1, the upper copper foil roller 2 and the lower copper foil roller 3 and the three pressing plates 7.
[0031] In actual application of this embodiment, the surfaces of the substrate and the two copper foils can be cleaned by a number of cleaning brushes 9 to remove dust or impurities, so that the pressed copper clad laminate is less likely to have depressions or protrusions, thereby further ensuring the quality of the copper clad laminate.

During the winding process, the substrate and the two sets of copper foils will move to the cleaning brush 9. The cleaning brush 9 cleans the surfaces of the substrate and the two sets of copper foils to make them clean and smooth. Step S3: After being cleaned by the cleaning brush 9, the pressing plate 7 presses the substrate or copper foil to flatten the wrinkled or bent parts of the substrate or copper foil; Step S4: After being flattened by the pressing plate 7, the substrate or copper foil enters the auxiliary mechanism 6. The two sets of inclined rollers 63 rotate to pull the substrate or copper foil to both sides to prevent the substrate or copper foil from shifting and keep the substrate or copper foil in the middle position. Step S5: After passing through the auxiliary mechanism 6, the suction cup 51 in the anti-deflection mechanism 5 on the anti-deflection roller 4 will suck the substrate or copper foil when it moves to the highest point of the anti-deflection roller 4. When the suction cup 51 moves away from the anti-deflection roller 4, the substrate or copper foil is released, so that the position of the substrate or copper foil remains unchanged during the movement; Step S6: After passing through the anti-deflection mechanism 5 , the substrate and the two sets of copper foils will always be located in the middle position due to the limitation of the anti-deflection plate 8 .

During the reeling process, the substrate and the two sets of copper foils are moved to the cleaning brush (9). The cleaning brush (9) cleans the surfaces of the substrate and the two sets of copper foils to make them clean and smooth. Step S3: After cleaning by the cleaning brush (9), the pressing plate (7) presses the substrate or copper foil to flatten the wrinkled or bent parts of the substrate or copper foil; Step S4: After being flattened by the pressing plate (7), the substrate or copper foil enters the auxiliary mechanism (6), and the two sets of inclined rollers (63) rotate to pull the substrate or copper foil to both sides to prevent the substrate or copper foil from deviating and keep the substrate or copper foil in the middle position; Step S5: After passing through the auxiliary mechanism (6), the suction cup (51) in the anti-deflection mechanism (5) on the anti-deflection roller (4) will suck the substrate or copper foil when it moves to the highest point of the anti-deflection roller (4), and release the substrate or copper foil when the suction cup (51) moves away from the anti-deflection roller (4), so that the position of the substrate or copper foil remains unchanged during the movement; Step S6: After passing through the anti-deflection mechanism (5), the substrate and the two sets of copper foils will always be located in the middle position due to the limitation of the anti-deflection plate (8).
