Description

Technical Field

[0001] The present invention provides a aging and drying device for a breathable substrate, in particular, a device that can be rolled up and receive a substrate and allow high-temperature gas to be introduced and distributed on the substrate, so that the base material disposed on the substrate can be fully and evenly heated and aged. Background Art

[0002] The sheet-like substrate is usually placed on a carrier to facilitate storage, stacking and transportation. When processing is required, the substrate is processed together with the carrier, and then the substrate can be separated from the carrier for use. Therefore, its process is often used for intermediate products such as printed circuit boards.

[0003] In the prior art, for the curing of soft board materials, the soft board materials are placed on a metal heat-conducting plate, and after being rolled into a roll, they are directly placed in an oven to apply high temperature so that the soft board materials can be cured. However, there is no relevant guide device in the oven. In addition, after the soft board materials are rolled up, the upper and lower end surfaces are tightly attached to the metal heat-conducting plate. Therefore, even if high temperature is applied in the oven, the temperature can only be directly convected at the side edges of the rolled soft board materials, and cannot be effectively conducted to the center of the soft board materials. Therefore, it will cause the soft board materials to have uneven substrates due to uneven heating, and incomplete curing, which will affect the quality and accuracy of subsequent processing or output of finished products.

[0004] Although the prior art provides another substrate structure, the substrate is provided with holes and a pad is arranged at the hole, so that after being rolled up and stacked, the substrate carried on the substrate will not contact the stacked substrate, so that after stacking, the air can still flow to the surface of the substrate through the aforementioned holes, so that it can be heated evenly; however, if a general oven is still used for baking, because it has no guiding function, it is still difficult to effectively guide the high-temperature gas to the surface of the substrate, and it needs to be heated for a long time to make the internal temperature as consistent as possible, so that the substrate can be completely cured. However, its curing efficiency is not good, which will lead to energy consumption and increase the time cost of the curing process.

[0005] In view of this, the inventor has devoted himself to further research on the equipment for maturing substrates, and has started to carry out research and development and improvement, hoping to find a better invention to solve the above problems. After continuous testing and modification, the present invention is born. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned problems. In order to achieve the above purpose, the inventors provide a aging and drying equipment for breathable substrates, which includes: a box body, a containing chamber is formed inside, a receiving shaft and a receiving plate are fixed inside the containing chamber, and the receiving shaft is vertically penetrated through the receiving plate; the receiving shaft is used to roll up and stack a substrate, and the receiving plate is correspondingly received by the substrate; the containing chamber is provided with an air inlet and an air outlet.

[0007] According to the above-mentioned aging and drying equipment for the breathable substrate, the receiving plate divides the chamber into a first receiving space and a second receiving space, the air inlet is arranged at the first receiving space, and the receiving shaft is used to roll up and stack the substrate at the first receiving space, while the air outlet is arranged at the second receiving space, and the receiving plate is also provided with a plurality of axial through holes corresponding to the receiving shaft.

[0008] According to the above-mentioned air-permeable substrate aging and drying equipment, the receiving shaft is uprightly arranged in the box body, the bottom end of the receiving shaft is fixedly arranged on the bottom wall of the chamber, and the top of the chamber is provided with the air inlet.

[0009] According to the above-mentioned aging and drying equipment for the breathable substrate, the air inlet corresponds to the axial direction of the receiving shaft.

[0010] According to the above-mentioned aging and drying equipment for breathable substrates, the air inlet is provided with a positive pressure device, and the positive pressure device is used to apply positive pressure air intake to the interior of the box.

[0011] According to the above-mentioned air permeable substrate aging and drying equipment, the air inlet and the air outlet are connected to each other through a pipeline at one end opposite to the box body.

[0012] According to the above-mentioned aging and drying equipment for breathable substrates, the air outlet is provided with a negative pressure device, and the negative pressure device is used to apply negative pressure to exhaust air from the air outlet.

[0013] According to the above-mentioned air permeable substrate maturation and drying equipment, the air inlet and the air outlet are at one end opposite to the box body and are further connected to each other through a pipeline.

[0014] According to the above-mentioned aging and drying equipment for the breathable substrate, when the substrate is rolled up and stacked, a through hole is formed at the side edges of both ends thereof, and the through hole corresponds to the axial direction of the receiving shaft.

[0015] According to the above-mentioned aging and drying equipment for the breathable substrate, at least one base material is also arranged on the surface of the substrate, and the base material is a metal or a polymer material.

[0016] From the above description and configuration, it is apparent that the present invention mainly has the following advantages and effects, which are described in detail as follows:

[0017] 1. The present invention can reliably position the substrate in the box after rolling it up by means of the arrangement of the receiving shaft and the receiving plate, and can guide the high-temperature gas into the container by means of the arrangement of the air inlet and the air outlet, and can promote the heat balance inside the container, so that the substrate arranged on the substrate can be evenly heated and cured to improve its quality, and has a high degree of reliability and precision when it is subsequently processed or applied to related products.

[0018] 2. The present invention divides the chamber into a first accommodating space and a second accommodating space through a receiving plate, and the receiving shaft rolls up the stacked substrates in the first accommodating space. The air inlet can input high-temperature gas from the first accommodating space, so that the high-temperature gas can be directly or fully circulated in the first accommodating space. Afterwards, the high-temperature gas can be heat-convected to the surface of the substrate, thereby allowing the substrate to be heated evenly. Then, the high-temperature gas can flow from the through hole to the second accommodating space and be discharged through the air outlet, thereby effectively improving the heating inside the chamber and the efficiency of maturing the substrate.

[0019] 3. The present invention can further promote thermal balance by arranging the air inlet corresponding to the axial direction of the receiving shaft and disposing the positive pressure device and the negative pressure device, and can force the high-temperature gas to flow through the surface of the substrate sufficiently, thereby improving its curing efficiency.

DETAILED DESCRIPTION

[0025] Regarding the technical means of our inventors, several preferred embodiments are described in detail below with reference to the accompanying drawings to facilitate understanding and recognition of the present invention.

[0026] First, see Figure 1As shown, the present invention is a aging and drying device for a breathable substrate, which includes:

[0027] A box body 1 is provided with a chamber 11 inside, a receiving shaft 12 and a receiving plate 13 are fixedly provided inside the chamber 11, and the receiving shaft 12 is vertically penetrated through the receiving plate 13; the receiving shaft 12 is used to roll up and stack a substrate 3, and the receiving plate 13 is correspondingly received on the substrate 3; the chamber 11 is provided with an air inlet 14 and an air outlet 15; wherein, the configuration of the air inlet 14 and the air outlet 15 can be longitudinally, transversely or obliquely connected to the chamber 11 according to the requirements, but it is only an example for illustration and is not intended to be limiting.

[0028] Thus, the air inlet 14 can be connected to a heating device (not shown), which can be used to supply high-temperature gas, so that the high-temperature gas can be input into the chamber 11 through the air inlet 14 and flow inside the chamber 11 to ensure heat convection on the rolled and stacked substrates 3, so that the substrates 3 can be heated evenly; and in one embodiment, the substrate 3 can be a material with high thermal conductivity, such as a metal heat-conducting plate, and a base material 31 can be provided on the end surface of the substrate 3, which can be any material that needs to be output, produced or matured to facilitate the use of subsequent products or intermediate products, so the base material 31 can be a metal or polymer material, such as copper foil, aluminum, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyethylene (PE), polyimide (PI) and other materials are used to facilitate the subsequent manufacturing process; therefore, the high-temperature gas can also contact the substrate 31 so that the substrate 31 can be cured, and the volatile substances in the curing process can also be discharged from the air outlet 15 due to the flow of the high-temperature gas. By this arrangement, the thermal balance inside the chamber 11 can be promoted, so that the temperature inside the chamber can be quickly uniformized, so that the substrate 31 can be evenly heated and cured, and the high temperature or temperature unevenness can be prevented from affecting the quality or flatness of the substrate 31, and the stability of the substrate 31 during feeding, as well as the quality and accuracy of the produced finished products can be improved.

[0029] In one embodiment, the receiving plate 13 divides the chamber 11 into a first receiving space 11A and a second receiving space 11B, the air inlet 14 is arranged at the first receiving space 11A, and the receiving shaft 12 rolls up and stacks the substrate 3 at the first receiving space 11A, and the air outlet 15 is arranged at the second receiving space 11B, and the receiving plate 13 is also penetrated with a plurality of axial through holes 131 corresponding to the receiving shaft 12; when high-temperature gas is input, the high-temperature gas can fully circulate and convect in the first receiving space 11A, so that it can evenly convect on the surface of the substrate 31 and the substrate 3, and can flow to the second receiving space 11B through the through holes 131, and then be discharged from the air outlet 15.

[0030] In a preferred embodiment, the receiving plate 13 is formed with a bearing area 132 and an isolation area 133, wherein the receiving plate 13 receives the substrate 3 via the bearing area 132, and the receiving plate 13 is only provided with a through hole 131 in the bearing area 132. In addition, when the substrate 3 is rolled up and stacked, a through hole 32 is formed at the side edges of both ends thereof, and the through hole 32 is provided corresponding to the axial direction of the receiving shaft 12; for example, Figure 2 , 3 As shown, the substrate 3 is provided with at least one venting portion 33 at the end surface, and a receiving component 34 is provided on the venting portion 33 of the substrate 3, and the receiving component 34 does not completely cover the venting portion 33, and at least one of the venting portions 33 is covered by the receiving component 34, and a gap 35 is formed on the two opposite sides of the receiving component 34, and the thickness of the substrate 31 is equal to or less than the height of the receiving component 34; thereby, the substrate 3 will form the through hole 32 by means of the gap 35 and the venting portion 33; and by means of the above-mentioned arrangement, when the receiving plate 13 receives the substrate 3, due to The isolation area 133 does not have the through hole 131, so it is completely non-ventilated. Therefore, the high-temperature gas in the first accommodation space 11A cannot directly pass through the isolation area 133 of the receiving plate 13 to flow to the second accommodation space 11B, but must directly or circulate in the first accommodation space 11A and flow through the through hole 32 formed by the stacked substrates 3 before flowing through the through hole 131 to the second accommodation space 11B. This ensures that the input high-temperature gas can transfer its heat to the substrate 3 and the base material 31, thereby effectively improving the efficiency of heat transfer, heat balance and aging, and reducing energy consumption.

[0031] As for the configuration of the receiving shaft 12, in one embodiment, in order to facilitate the receiving and positioning configuration of the receiving shaft 12 and the receiving plate 13 for the substrate 3, in one embodiment, the receiving shaft 12 is vertically arranged in the box body 1, and because the receiving plate 13 is perpendicular to the receiving shaft 12, the receiving plate 13 will be arranged horizontally and correspondingly arranged on the wall of the chamber 11. As mentioned above, since the isolation area 133 is completely unable to allow high-temperature gas to pass through, the periphery of the receiving plate 13 is sealed with the wall of the chamber 11, thereby separating the chamber 11 into a first accommodating space 11A and a second accommodating space 11B. The receiving shaft The bottom end of 12 is fixedly arranged on the bottom wall of the chamber 11, and the top of the chamber 11 is provided with the air inlet 14, so it can be known that the first accommodation space 11A will be located at the upper part of the chamber 11, and the second accommodation space 11B will be located at the lower part of the chamber 11. By means of this arrangement, the substrate 3 and its base material 31 can be stably carried and can be stably positioned during the heating and curing process, and will not be easily shaken by the flow force of the high-temperature gas. The substrate 3 can be pressed against the receiving plate 13, so that no gap is generated between the bottom of the substrate 3 and the receiving plate 13, so that the high-temperature gas flowing through the through hole 32 can directly enter the second accommodation space 11B.

[0032] As for the configuration of the air inlet 14, it is preferably corresponding to the axial direction of the receiving shaft 12, so that when the high-temperature gas is input into the chamber 11, it can flow more directly to the substrate 31 and pass through the through hole 32 formed by the rolled and stacked substrate 31, so as to further improve its heating and maturation efficiency.

[0033] In other embodiments, in order to promote the flow of high-temperature gas, the air inlet 14 is provided with a positive pressure device 16, and the positive pressure device 16 is used to apply positive pressure to the interior of the box 1 to intake air. A negative pressure device 17 can also be provided at the air outlet 15, and the negative pressure device 17 is used to apply negative pressure to exhaust air from the air outlet 15. The positive pressure device 16 and the negative pressure device 17 can promote the flow of high-temperature gas by setting either one of them, and preferably, they can be set at the same time to greatly enhance the convection capacity and further improve the heating and maturation efficiency.

[0034] In another embodiment, it can also be configured as follows Figure 4 As shown, the air inlet 14 and the air outlet 15 are connected to each other at one end relative to the box body 1 through a pipeline 18, and the heating device can be arranged on the pipeline 18, so that the high-temperature gas can be continuously heated and circulated in the chamber 11, and through the above-mentioned effect, the uniform heating and aging efficiency can be improved. In addition, the high-temperature gas can be circulated and heated to prevent thermal pollution to the outside world, and energy consumption can be saved, so as to achieve energy-saving and environmental protection effects.

[0035] The above are only several preferred embodiments of the present invention, which cannot be used to limit the scope of the present invention. That is, all equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description should still fall within the scope covered by the patent of the present invention.
