[0032] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.
[0033] In order to solve the technical problems mentioned in the background section, the inventors have innovatively designed the following technical solutions, and the specific implementation scheme of this application will be described in detail below with reference to the accompanying drawings.
[0034] Please see Figure 1 , Figure 1 This is a front view of a dry film pressing bubble adjustment assembly 1 provided in this embodiment. The dry film pressing bubble adjustment assembly 1 includes a substrate 10, a film feeding cylinder 20, a hot pressing roller 30, and a vacuum pumping component 40.
[0035] A film feeding cylinder 20 is disposed on one side of the substrate 10, and a dry film 2 to be pressed is wound on the film feeding cylinder 20. A hot pressing roller 30 is disposed close to the substrate 10 and on the same side of the substrate 10 as the film feeding cylinder 20. The dry film 2 to be pressed is conveyed from the film feeding cylinder 20 to the side of the hot pressing roller 30 away from the film feeding cylinder 20. The hot pressing roller 30 is used to press the dry film 2 to be pressed onto the substrate 10.
[0036] In this embodiment, the design of the film feeding cylinder 20 allows for continuous transport of the dry film 2 to be pressed, ensuring the continuity and stability of the pressing of the dry film 2 and the substrate 10. The dry film 2 to be pressed is transported from the film feeding cylinder 20 to the side of the hot pressing roller 30 away from the film feeding cylinder 20, and there is a pressing and bonding area between the dry film 2 to be pressed and the substrate 10. Then, the dry film 2 to be pressed is pressed onto the substrate 10 by hot pressing.
[0037] It is worth noting that the temperature of the hot press roller 30 is not specifically limited here and should be selected according to the actual situation.
[0038] The vacuuming component 40 is located between the dry film 2 to be pressed and the substrate 10. The vacuuming component 40 includes a vacuum nozzle 410, which faces the area where the dry film 2 to be pressed and the substrate 10 are pressed and bonded, and is used to remove the air between the dry film 2 to be pressed and the substrate 10 or the dust on the substrate 10.
[0039] In this embodiment, the vacuum pump 40 removes air between the dry film 2 to be pressed and the substrate 10, or dust from the substrate 10. The gas flow direction within the vacuum pump 40 is as follows: Figure 1 As indicated by the arrow, a negative pressure is formed in the area where the dry film 2 to be pressed and the substrate 10 are pressed and bonded, reducing the number of gas molecules in the area, so that the dry film 2 to be pressed can better adhere to the substrate 10 and reduce the generation of bubbles.
[0040] In addition, the vacuum pump 40 can move relative to the substrate 10, which can more precisely control the negative pressure area between the dry film 2 to be pressed and the substrate 10, and enhance the consistency of the bonding between the dry film 2 to be pressed and the substrate 10.
[0041] Further, please see Figure 1 and Figure 2 , Figure 2 This is a side view of a dry film pressing bubble adjustment assembly 1 provided in this embodiment. The dry film pressing bubble adjustment assembly 1 also includes a conveyor wheel 50 and a driving member (not shown in the figure). The driving member is connected to the conveyor wheel 50. The conveyor wheel 50 is located on the side of the substrate 10 away from the hot pressing wheel 30. The driving member drives the conveyor wheel 50 to rotate so that the substrate 10 moves along the first direction A1 toward the side away from the film feeding cylinder 20.
[0042] In this embodiment, the main function of the conveyor wheel 50 is to guide and move the substrate 10, causing it to move along the first direction A1 toward the side away from the film feeding cylinder 20, and to transport the substrate 10 with pressed dry film to the next stage. The drive unit is connected to the conveyor wheel 50, and its main function is to provide rotational power to the conveyor wheel 50. The drive unit can be a motor, gear, or other mechanical transmission device. The type of drive unit is not specifically limited here and should be selected according to the actual situation.
[0043] Furthermore, please see again Figure 1 and Figure 2 There are multiple conveyor rollers 50, which extend along the second direction A2. The multiple conveyor rollers 50 are arranged at equal intervals on the side of the substrate 10 away from the hot pressing roller 30. The first direction A1 and the second direction A2 are perpendicular to each other, and the film feeding cylinder 20 also extends along the second direction A2.
[0044] In this embodiment, there can be multiple conveying wheels 50, and the conveying wheels 50 are arranged at equal intervals on the side of the substrate 10 away from the hot pressing wheel 30. This design helps to distribute the weight of the substrate 10 and provide more uniform support and driving force for the substrate 10.
[0045] Furthermore, please see again Figure 1 and Figure 2 The dry film pressing bubble adjustment assembly 1 also includes a pressing component 60, which is located between the film feeding cylinder 20 and the hot pressing roller 30. The dry film 2 to be pressed is conveyed from the film feeding cylinder 20 to the side of the hot pressing roller 30 away from the film feeding cylinder 20 via the pressing component 60. The pressing component 60 is used to tighten the dry film 2 to be pressed.
[0046] In this embodiment, the pressing component 60 is located between the film feeding cylinder 20 and the hot pressing roller 30, and its main function is to tighten the dry film 2 to be pressed. By precisely controlling the tension of the dry film 2 to be pressed, the pressing component 60 ensures that the dry film 2 to be pressed maintains an appropriate tension during the transportation process from the film feeding cylinder 20 to the hot pressing roller 30, reduces the looseness and wrinkles of the dry film 2 to be pressed during the transportation process, ensures the flatness of the dry film 2 to be pressed, and thus improves the bonding quality between the dry film 2 to be pressed and the substrate 10.
[0047] In addition, the pressing component 60 provides support for the dry film 2 to be pressed. Due to the support of the pressing component 60, the dry film 2 to be pressed can remain flat before pressing, which helps to improve the contact uniformity between the dry film 2 to be pressed and the substrate 10, thereby achieving a more uniform pressing effect.
[0048] Further, please see Figure 1 The shape of the pressing component 60 near the dry film 2 to be pressed is arc-shaped, and the pressing component 60 near the dry film 2 to be pressed is completely in contact with the dry film 2 to be pressed.
[0049] In this embodiment, the pressing member 60 has an arc shape on the side near the dry film 2 to be pressed. This design allows the pressing member 60 to fully adhere to the dry film 2, ensuring that the dry film 2 remains flat during transport. This helps to achieve uniform contact between the dry film 2 and the substrate 10, improving the pressing effect. In addition, by pre-stretching and flattening the dry film 2, the pressing member 60 also helps to reduce air between the dry film 2 and the substrate 10, thereby reducing the generation of air bubbles.
[0050] Further, please see Figure 2 In the second direction A2, the width of the pressing member 60 is greater than or equal to the width of the dry film 2 to be pressed.
[0051] In this embodiment, the width of the pressing member 60 is greater than or equal to the width of the dry film 2 to be pressed, ensuring that the pressing member 60 can fully cover the dry film 2 to be pressed. This helps the pressing member 60 provide uniform tension across the entire width of the dry film 2 to be pressed, avoiding loosening or uneven stretching of the dry film 2 due to insufficient local tension or overload. By ensuring that the pressing member 60 fully covers the dry film 2 to be pressed, the risk of wrinkles forming during the pressing process can be reduced, thereby improving the quality of the final product.
[0052] It is worth noting that the width of the pressing part 60 and the width of the dry film 2 to be pressed are not specifically limited here, and should be selected according to the actual situation.
[0053] Further, please see Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of the vacuuming component 40 provided in this embodiment. The vacuum nozzle 410 has a rectangular shape, and the long side of the vacuum nozzle 410 extends along the second direction A2.
[0054] In this embodiment, the vacuum nozzle 410 faces the area where the dry film 2 and the substrate 10 are bonded. The vacuum nozzle 410 is rectangular in shape, and its long side extends along the second direction A2, allowing it to cover a wider area and increasing the contact area between the vacuum nozzle 410 and the bonding area of the dry film 2 and the substrate 10. The vacuum pump 40 removes air from the bonding area of the dry film 2 and the substrate 10 through the vacuum nozzle 410, creating a negative pressure in the bonding area and reducing air retention, thereby reducing the risk of air bubbles. Simultaneously, the vacuum pump 40 can also remove dust from the substrate 10 through the vacuum nozzle 410, ensuring good contact between the dry film 2 and the substrate 10 and improving the bonding quality.
[0055] Further, please see Figure 2 In the second direction A2, the length of the vacuum nozzle 410 is greater than the width of the dry film 2 to be pressed.
[0056] In this embodiment, the length of the vacuum nozzle 410 is greater than the width of the dry film 2 to be pressed, ensuring that during the adsorption process, the area adsorbed by the vacuum nozzle 410 can cover the area where the dry film 2 to be pressed and the substrate 10 are pressed and bonded, so that the air or dust in the area where the dry film 2 to be pressed and the substrate 10 are pressed and bonded is completely adsorbed, thereby improving the bonding quality of the dry film 2 to be pressed and the substrate 10.
[0057] Further, please see Figure 4 , Figure 4 for Figure 1 The enlarged view within the dashed box shows that the distance between the vacuum nozzle 410 and the substrate 10 in the direction perpendicular to the substrate 10 ranges from 20 micrometers to 30 micrometers.
[0058] In this embodiment, the distance d between the vacuum nozzle 410 and the substrate 10 in the direction perpendicular to the substrate 10 includes 20 micrometers to 30 micrometers. For example, the distance d between the vacuum nozzle 410 and the substrate 10 includes 20 micrometers, 22 micrometers, 24 micrometers, 26 micrometers, 28 micrometers and 30 micrometers.
[0059] The distance d between the vacuum nozzle 410 and the substrate 10 is kept between 20 micrometers and 30 micrometers. Too close a distance will cause physical damage to the dry film 2 to be pressed and the substrate 10, while too far a distance will cause the vacuum nozzle 410 to not completely adsorb the area. Therefore, keeping the distance d between 20 micrometers and 30 micrometers ensures the stability of the adsorption of the vacuum nozzle 410 and more effectively removes air or dust from the substrate 10 in the bonding area between the dry film 2 to be pressed and the substrate 10.
[0060] Based on the same inventive concept, another objective of this application is to provide a dry film laminating device, which includes any of the aforementioned dry film laminating bubble adjustment components 1. The dry film laminating bubble adjustment component 1 reduces the generation of bubbles between the dry film 2 to be pressed and the substrate 10, so that the substrate 10 with the pressed dry film can maintain better flatness and quality when it is subjected to the next stage in the dry film laminating device, thereby improving the efficiency of the entire production process and the quality of the final product.
[0061] In summary, this application provides a dry film pressing bubble adjustment assembly and a dry film pressing device. The dry film pressing bubble adjustment assembly includes a substrate, a film feeding cylinder, a hot press roller, and a vacuum pump. The film feeding cylinder is disposed on one side of the substrate, and the dry film to be pressed is wound on the film feeding cylinder. The hot press roller is disposed close to the substrate and on the same side of the substrate as the film feeding cylinder. The dry film to be pressed is transported from the film feeding cylinder to the side of the hot press roller away from the film feeding cylinder, and the hot press roller is used to press the dry film to be pressed onto the substrate. The vacuum pump is located between the dry film to be pressed and the substrate, and includes a vacuum nozzle facing the area where the dry film to be pressed and the substrate are pressed together, used to remove air between the dry film to be pressed and the substrate or dust on the substrate. Thus, the above structure can significantly improve the bubble formation after the dry film to be pressed and the substrate are bonded, thereby effectively improving the product yield in the production process.
[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
