Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible copper clad laminate technology, and in particular to an anti-condensation device for flexible copper clad laminates. Background Technology
[0002] Flexible copper-clad laminates are a key material in electronics manufacturing, used in the production of circuit boards for electronic devices such as smartphones and tablets. During production, the substrate needs to be coated with adhesive to increase adhesion to the copper foil. After adhesive coating, the substrate is transported upwards to a drying oven. Condensation easily forms on the conveyor section between the coating unit and the drying oven, causing the substrate to slip and affecting production efficiency. Traditional air-blowing drying and dehumidification methods can easily blow dust onto the adhesive surface, reducing product quality. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an anti-condensation device for flexible copper-clad laminates, which achieves the effect of preventing condensation through dustproof design and multi-point exhaust dehumidification via distributed pipes, thus solving the problem of slippage during conveying.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A condensation prevention device for flexible copper-clad laminates, comprising:
[0006] A dustproof conveying chamber, wherein multiple rotating shaft structures are arranged horizontally from low to high inside the dustproof conveying chamber. The rotating shaft structures are used to tilt upwards to convey a substrate with adhesive coated on its upper surface. The rotating shaft structures include a first rotating shaft and a second rotating shaft that is set at a height higher than the first rotating shaft.
[0007] The anti-condensation mechanism includes a main pipe located at the bottom of the inner side of the dustproof conveying chamber, multiple branch pipes vertically arranged on the main pipe, and an exhaust dehumidification device connected to the main pipe located on the outside of the dustproof conveying chamber. The exhaust dehumidification device can draw air from the branch pipes and discharge it outside the dustproof conveying chamber.
[0008] According to some embodiments of the present invention, the side wall of the branch pipe is provided with multiple side air intakes.
[0009] According to some embodiments of the present invention, the top of the branch pipe is provided with a detachable suction cover, and the suction cover has multiple suction holes.
[0010] According to some embodiments of the present invention, the branch pipe includes a plurality of first branch pipes disposed below the rotating shaft structure.
[0011] According to some embodiments of the present invention, the first branch pipe is disposed below the second rotating shaft, and the side air intakes on the first branch pipe are all disposed on the side facing the first rotating shaft.
[0012] According to some embodiments of the present invention, the opening direction of the side air intake is parallel to the conveying direction of the substrate between the first rotating shaft and the second rotating shaft.
[0013] According to some embodiments of the present invention, the sub-pipe includes a plurality of second sub-pipes disposed on the side of the rotating shaft structure.
[0014] According to some embodiments of the present invention, the height of the second sub-pipe gradually increases with the conveying height of the substrate disposed on the rotating shaft structure, and the side suction ports on the second sub-pipe all face the inner side of the dustproof conveying chamber.
[0015] According to some embodiments of the present invention, the exhaust dehumidification device includes a fan for exhausting air from the branch pipe to the outside of the dustproof conveying chamber and a condenser for condensing the moisture in the air into water.
[0016] This utility model has at least the following beneficial effects:
[0017] The rotating shaft structure is located inside the dustproof conveying chamber, effectively preventing external dust from entering and protecting the substrate from condensation. The anti-condensation mechanism draws air from the flexibly arranged branch pipes to the main pipe, and then the air is processed and dehumidified by the external anti-condensation mechanism before being discharged. Multiple branch pipes enable multi-point air extraction and rapid air discharge, effectively balancing the temperature difference inside the dustproof conveying chamber and simultaneously achieving anti-condensation and dehumidification functions.

[0021] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0022] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.
[0024] An embodiment of this utility model provides an anti-condensation device for flexible copper-clad laminates, such as... Figure 1-3 As shown, it includes:
[0025] The dustproof conveying chamber 2 has multiple rotating shaft structures 3 arranged horizontally from low to high inside. The rotating shaft structures 3 are used to tilt upwards to convey the substrate 1 with glue coated on the upper surface. The rotating shaft structure 3 includes a first rotating shaft 301 and a second rotating shaft 302 with a height higher than the first rotating shaft 301.
[0026] The anti-condensation mechanism 4 includes a main pipe 401 located at the bottom of the inner side of the dustproof conveying chamber 2, multiple branch pipes 402 vertically arranged on the main pipe 401, and an exhaust dehumidification device 403 located on the outside of the dustproof conveying chamber 2 and connected to the main pipe 401. The exhaust dehumidification device 403 can draw air from the branch pipes 402 and discharge it to the outside of the dustproof conveying chamber 2.
[0027] The rotating shaft structure 3 tilts upwards to convey the substrate 1 coated with adhesive, facilitating its entry into the drying chamber. Located within the dustproof conveying chamber 2, the rotating shaft structure 3 effectively prevents external dust and other impurities from entering, protecting the adhesive-coated substrate 1 from contamination before it enters the drying chamber, ensuring its cleanliness during transport, and thus improving product quality. The rotating shaft structure 3 is arranged horizontally from low to high; for example, in this embodiment, a second rotating shaft 302 is higher than the first rotating shaft 301. Furthermore, a third rotating shaft with a height higher than the second rotating shaft 302 can be arranged on one side of the second rotating shaft 302. When the substrate 1 moves on the tilted rotating shaft, the adhesive flows locally along the direction of movement, achieving self-leveling. Compared to a downward tilt, this reduces adhesive accumulation and improves quality. The design of the main pipe 401 and branch pipes 402 of the anti-condensation mechanism 4 allows the exhaust dehumidifier 403 to effectively draw air from multiple branch pipes 402 before uniformly conveying it from the main pipe 401 to the exhaust dehumidifier 403 for processing. This multi-pipe system 402 enables multi-point air extraction, rapidly drawing air out of the dustproof conveying chamber 2, reducing temperature differences within the chamber, and achieving dehumidification while preventing condensation. The pipes 402 can be installed at the top, bottom, or sides of the dustproof conveying chamber 2, allowing for flexible air extraction depending on the scenario. This suction-and-decondensation method avoids the problem of dust being agitated onto the substrate 1 by a blowing structure, while simultaneously preventing condensation. The dehumidification device 403 is located on the outside of the dustproof conveying chamber 2, preventing dust from being stirred up and affecting product quality. Exhausting moisture through the anti-condensation mechanism 4 prevents the adhesive on the substrate 1 from absorbing excessive moisture. If the adhesive absorbs moisture, its performance deteriorates, such as weakened adhesion and prolonged curing time. Furthermore, excessive moisture may cause problems like air bubbles in subsequent processes. This anti-condensation device maintains a suitable humidity environment within the conveying chamber, ensuring stable adhesive performance on the substrate 1, thus providing a good foundation for subsequent processes such as copper plating.
[0028] In some embodiments, such as Figure 1-2 As shown, multiple side air intakes 404 are provided on the side wall of the branch pipe 402.
[0029] Compared to omnidirectional air intake, the side air intake 404 can target a specific area for air intake, better protecting the substrate 1 after adhesive coating from contamination. Combined with multiple branch pipes 402, it improves product quality and production efficiency.
[0030] Furthermore, such as Figure 2 As shown, a removable suction cover 405 is provided on the top of the branch pipe 402, and the suction cover 405 has multiple suction holes 406.
[0031] The detachable air intake cover 405 is easy to install and maintain. Dust can easily fall into the top. When cleaning or changing the air outlet according to different needs, it can be easily removed without affecting the normal operation of the entire device. At the same time, the multiple air intake holes 406 on the air intake cover 405 act as a filter.
[0032] In some embodiments, such as Figure 1-2 As shown, the branch pipe 402 includes a plurality of first branch pipes 407 disposed below the rotating shaft structure 3.
[0033] The first branch pipe 407 is located below the rotating shaft structure 3, and its suction position is located on the bottom surface of the substrate 1. The air disturbance caused by the suction is cleverly set on the bottom surface to reduce the possibility of dust drifting in from the glue applied on the top surface. At the same time, the suction force located below the rotating shaft structure 3 can bring the substrate 1 closer to the rotating shaft structure 3. It also suctions the rotating shaft structure 3, further reducing the problem of the substrate 1 slipping on the rotating shaft structure 3. It can directly and effectively dehumidify the substrate 1 and the rotating shaft structure 3 during the conveying process. The setting of multiple first branch pipes 407 can ensure the uniformity of dehumidification.
[0034] Furthermore, such as Figure 1-2 As shown, the first branch pipe 407 is located below the second rotating shaft 302, and the side air intakes 404 on the first branch pipe 407 are all located on the side facing the first rotating shaft 301.
[0035] Since the first branch pipe 407 is located below the second rotating shaft 302, its position can accurately cover the key areas of the substrate 1 during the conveying process, especially the parts of the substrate 1 that are prone to moisture accumulation when conveyed at an angle. At the same time, the side suction port 404 faces the side of the first rotating shaft 301, which can be directly aligned with the direction from which the substrate 1 is conveyed and with the first rotating shaft 301 which is one level lower, forming an effective airflow guidance, stabilizing the temperature inside the chamber and quickly extracting moisture, reducing the residence time of moisture on the substrate 1 and the first rotating shaft 301; while the suction cover 405 can reduce condensation on the second rotating shaft 302, and the air vent can effectively prevent condensation from occurring.
[0036] Furthermore, such as Figure 2 As shown, the side air intake 404 is opened in a direction parallel to the conveying direction of the substrate 1 between the first rotating shaft 301 and the second rotating shaft 302.
[0037] The side suction port 404 can form a uniform and directional airflow along the conveying direction of the substrate 1, reduce the lateral interference of the airflow on the substrate 1, avoid the substrate 1 shaking or shifting due to airflow turbulence, and ensure the stability of the substrate 1 during the conveying process.
[0038] In some embodiments, such as Figure 3As shown, the branch pipe 402 includes a plurality of second branch pipes 408 disposed on the side of the rotating shaft structure 3.
[0039] The second branch pipe 408 is located on the side of the rotating shaft structure 3, which can effectively extract the moisture generated around the substrate 1 from the side, ensuring that the substrate 1 is continuously dehumidified during the conveying process, and further reducing the risk of condensation on the surface of the substrate 1.
[0040] Furthermore, such as Figure 3 As shown, the height of the second branch pipe 408 gradually increases with the conveying height of the substrate 1 set on the rotating shaft structure 3, and the side suction ports 404 on the second branch pipe 408 all face the inner side of the dustproof conveying chamber 2.
[0041] The gradually increasing height precisely adapts to the conveying path of the substrate 1. As the substrate 1 is conveyed at an upward tilt, the height of the second branch pipe 408 increases accordingly, ensuring that the dehumidification effect always covers the substrate 1 and the rotating shaft structure 3 below it. At the same time, the side suction port 404, located near the rotating shaft structure 3, can directly target the substrate 1 for dehumidification, preventing condensation from occurring.
[0042] In some embodiments, such as Figure 1 As shown, the exhaust dehumidification device 403 includes a fan for exhausting air from the branch pipe 402 to the outside of the dustproof conveying chamber 2 and a condenser for condensing the moisture in the air into water.
[0043] The fan can quickly extract air from the dustproof conveying chamber 2, reduce the humidity inside the chamber, balance the temperature difference at both ends, and prevent condensation on the substrate 1. At the same time, the condenser condenses the extracted moisture into water, effectively removing moisture from the air and preventing moisture from being directly discharged to the outside environment and causing environmental impact. The condenser condensing water to achieve the dehumidification effect is an existing technology and will not be described in detail here.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
