Description

Technical Field

[0001] The present invention relates to a preparation technology of a high thermal conductivity epoxy glass fiber cloth-based steel foil-clad plate, and in particular to a preparation method and device of a high thermal conductivity epoxy glass fiber cloth-based steel foil-clad plate. Background Art

[0002] Epoxy glass fiber cloth-based steel foil board is a composite material consisting of epoxy glass fiber cloth and steel foil board covering its surface. It has the advantages of high strength, high rigidity, corrosion resistance, and good conductivity. It is widely used in electronics, communications, aerospace and other fields.

[0003] At present, the preparation of epoxy glass fiber cloth-based steel foil-covered board requires first evenly applying epoxy resin glue on the surface of the glass fiber cloth tape, then laminating it with the steel foil board and performing hot pressing. The two bonded boards are then dried and cured to combine the steel foil and the epoxy glass fiber cloth into one, forming the epoxy glass fiber cloth-based steel foil-covered board.

[0004] At present, most people use dipping machines to complete the dipping process. During operation, the existing dipping machines can only dipping one roll of glass fiber cloth at a time, which has low working efficiency. In addition, during the dipping process, the glue in the dipping tank is often not mixed evenly, and wrinkles often appear on the surface of the glass fiber cloth, resulting in unsatisfactory dipping effect.

[0005] The Chinese invention patent with announcement number CN109056238B discloses a glass fiber cloth dipping system and a glass fiber cloth dipping method. The glass fiber cloth dipping system and the glass fiber cloth dipping method are provided with an oscillating mechanism, and the glass fiber cloth is then oscillated in the glue liquid, so that the glue liquid can better adhere to the surface of the glass fiber cloth. At the same time, the stirring shaft is driven to rotate by the stirring motor, and the stirring blade stirs the glue liquid, so that the glue liquid can be evenly distributed in the shell, ensuring the uniformity of dipping. It can also dip two glass fiber cloth rolls at the same time, thereby improving work efficiency. At the same time, an auxiliary device is provided. During the transportation of the glass fiber cloth, the rolling shaft provided on the pressing frame can smooth the wrinkles on the surface of the glass fiber cloth, and the scraper can remove excess The glue is scraped off to ensure the flatness of the upper and lower surfaces of the glass fiber cloth. However, in actual application, the force exerted by the upper and lower rolling shafts on the glass fiber cloth during the rolling process is only the force perpendicular to the glass fiber cloth. It can only achieve the same function as the scraper, that is, cleaning the excess glue on the surface of the glass fiber cloth. Even when the contact pressure between the rolling shaft and the glass fiber cloth is large, the glue inside the glass fiber cloth is also squeezed out, which makes it impossible to properly organize the wrinkled or stacked parts of the glass fiber cloth. At the same time, the excess glue is only scraped off by the scraper. As the glue accumulates, it will flow to both sides along the surface of the glass fiber cloth or the surface of the scraper and fall into the inside of the workbench, which will not only cause waste of glue, but also affect the working environment of the workbench.

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Example 1:

[0042] See also Figures 1-4 、 Figure 6-Figure 7 A device for preparing a high thermal conductivity epoxy glass fiber cloth-based steel foil-covered board includes a workbench 1, a plurality of guide rollers 2, and a dipping box 3. The guide rollers 2 are provided with glass fiber cloth tapes 6 on their exteriors. The device also includes:

[0043] There are two mounting cavities 4, which are symmetrically arranged on both sides of the workbench 1;

[0044] The cleaning and correcting mechanism 5 includes a rotating shaft 51 rotatably connected to the inner walls of the two mounting cavities 4. A connecting block 52 is fixedly connected to the outside of the rotating shaft 51. Two sets of mounting bars 53 are symmetrically fixedly connected to both sides of the connecting block 52. The two sets of mounting bars 53 on the two rotating shafts 51 are staggered. A scraper 54 is provided at the bottom of the mounting bar 53. A driving assembly 55 is provided on the top of the workbench 1. The driving assembly 55 is used to drive the two rotating shafts 51 to rotate synchronously in opposite directions.

[0045] The mounting bar 53 includes an upper mounting bar 531 and a lower mounting bar 532 . The upper mounting bar 531 and the lower mounting bar 532 are symmetrically distributed at the upper and lower ends of the side surface of the connecting block 52 .

[0046] In this embodiment, the driving assembly 55 includes a mounting plate 551 fixedly connected to the top of the workbench 1, and a cavity is opened inside the mounting plate 551. A first gear 552 is fixedly connected to the outside of one rotating shaft 51, and a second gear 553 is meshed with the outside of the first gear 552. The second gear 553 and the outside of the other rotating shaft 51 are respectively fixedly connected to pulleys 554, and a transmission belt 555 is connected between the two pulleys 554.

[0047] In this embodiment, the second gear 553 is rotatably connected to the inner wall of the cavity, and the positions and specifications of the two scrapers 54 located on the upper mounting bar 531 and the lower mounting bar 532 correspond to the glass fiber tape 6, so that the upper and lower scrapers 54 can rotate synchronously to synchronously scrape off excess glue on the surface of the glass fiber tape 6.

[0048] The second gear 553 rotates and drives a pulley 554 to rotate. Under the transmission action of the transmission belt 555, the other pulley 554 rotates and drives the other shaft 51 to rotate, so that the two shafts 51 can rotate synchronously in the opposite directions. The shaft 51 drives the connecting block 52 to rotate during the rotation process. The rotation of the connecting block 52 drives all the mounting bars 53 outside it to rotate. The rotation of the mounting bar 53 drives the scraper 54 to rotate, so that the scraper 54 on the upper mounting bar 531 and the lower mounting bar 532 can rotate synchronously, thereby scraping off the excess glue attached to the upper and lower surfaces of the fiberglass cloth belt 6 at the same time. In addition, through the synchronous and opposite rotation of the mounting bars 53 staggered on the two shafts 51, the excess glue on the surface of the fiberglass cloth belt 6 can be fully scraped off during its movement.

[0049] Since the fiberglass cloth tape 6 is prone to wrinkles or partial stacking during the immersion process, and the local thickness after stacking is relatively large, the scraper 54 can also clean the stacked fiberglass cloth tape 6 locally during the rotation process, so that the fiberglass cloth tape 6 transported to the subsequent process can remain straight.

[0050] Example 2:

[0051] See also Figure 3-Figure 5 、 Figure 8-Figure 9 When the scraper 54 scrapes off the excess glue on the surface of the fiberglass tape 6, the scraped glue will adhere to the surface of the scraper 54. As the scraper 54 continues to work, the amount of glue attached to its surface will gradually increase. Under the action of the glue's own weight, the excess glue may flow to the surface of the fiberglass tape 6 again and spill onto the inside of the workbench 1 during the scraping process, which will not only greatly affect the working effect of the scraper 54, but also cause waste of glue. Therefore, this embodiment provides a technical solution based on the above embodiment: it also includes:

[0052] The cleaning mechanism 7 includes a collecting plate 71 fixedly connected to the inner wall of the mounting cavity 4, and a scraping portion 72 is respectively provided on the top and bottom of the collecting plate 71. An inclined guide surface 73 is provided on the surface of the collecting plate 71, and a collecting groove 75 corresponding to the inclined guide surface 73 is provided on the bottom of the collecting plate 71. The outside of the collecting plate 71 is fixedly connected to a guide pipe 76, and the outside of the workbench 1 is fixedly connected to a collecting box 77 connected to the guide pipe 76.

[0053] In this embodiment, the positions and specifications of the two scraping portions 72 are respectively adapted to the upper and lower scrapers 54 .

[0054] Specifically, during the synchronous rotation of the upper and lower scrapers 54 , when they are in contact with the upper and lower scraping parts 72 respectively, the scraping parts 72 cooperate to scrape and collect the glue attached to the surfaces of the upper and lower scrapers 54 .

[0055] In this embodiment, mounting grooves are provided on the opposite sides of the upper and lower mounting bars 53, and the scraper 54 is rotatably connected to the inner wall of the mounting groove. A limiting component 78 is provided inside the mounting bar 53, and the limiting component 78 includes a connecting shaft 781 fixedly connected to the outside of the scraper 54, the connecting shaft 781 is rotatably connected to the mounting bar 53, and a round roller 782 is fixedly connected to the outside of the connecting shaft 781, and a limiting groove 783 is provided on the outer surface of the round roller 782. A working chamber is provided inside the mounting bar 53, and a pressure block 784 is slidably connected to the inner wall of the working chamber. An extrusion spring 785 is fixedly connected between the top of the pressure block 784 and the top of the inner wall of the working chamber, and a limiting column 786 is fixedly connected to the bottom of the pressure block 784. A torsion spring 787 is fixedly installed between the connecting shaft 781 and the inner wall of the working chamber.

[0056] In this embodiment, the shape, position and size specifications of the limiting column 786 are all adapted to the limiting groove 783. The limiting column 786 can be slidably connected to the inside of the limiting groove 783, so that with the cooperation of the limiting column 786 and the limiting groove 783, a stable state can be maintained when the scraper 54 scrapes off excess glue on the surface of the fiberglass cloth tape 6.

[0057] In this embodiment, an auxiliary component 74 is provided inside the installation cavity 4, and the auxiliary component 74 includes a control console 741 symmetrically fixedly connected to the upper and lower ends of the inner side surface of the installation cavity 4, and guide slopes 742 are provided on both sides of the surface of the control console 741. The surface of the control console 741 is provided with a flat surface 743 located between the two guide slopes 742, and the outside of the pressure block 784 is fixedly connected to a slider 744.

[0058] In this embodiment, the position of the slider 744 corresponds to the console 741, and the slider 744 is slidingly connected to the inner side surface of the mounting bar 53. When the upper and lower sliders 744 move along the guide slope 742 to the flat surface 743, the slider 744 drives the upper and lower groups of limiting columns 786 to move out of the limiting groove 783 respectively.

[0059] When the slider 744 is in contact with the scraper 72, the scraper 54 is in contact with the scraper portion 72. When the slider 744 is in contact with the scraper portion ... 53 continues to rotate, and the bottom of the scraper 54 is blocked by the scraping portion 72, so that the glue on the surface of the scraper 54 can be scraped off. As the mounting strip 53 continues to rotate, the bottom of the scraper 54 is separated from the scraping portion 72. At this time, the slider 744 moves to the end of the flat surface 743 and slides along the other side of the guide inclined surface 742, so that under the action of the rebound force of the extrusion spring 785, the slider 744 can move downward and drive the limiting column 786 to move and reset.

[0060] The cam 784 is pressed against the top of the handle 786 and the bottom of the handle 787 is pressed against the top of the handle 788. The cam 784 is pressed against the top of the handle 788 and the bottom of the handle 789 is pressed against the handle 790. The cam 786 is pressed against the top of the handle 789 and the bottom of the handle 780 is pressed against the handle 791. Under the scraping action of the scraping portion 72, the glue attached to the surface of the scraper 54 can be scraped off. During the scraping process, the scraper 54 itself will rotate and drive the torsion spring 787 to compress. When the scraper 54 is separated from the scraping portion 72, the scraper 54 can be rotated and reset under the action of the rebound force of the torsion spring 787. Moreover, after the slider 744 moves and separates from the console 741, the pressure block 784 moves in the opposite direction and resets under the action of the rebound force of the extrusion spring 785, and drives the limiting column 786 to move into the limiting groove 783, so that the rotation of the scraper 54 is restricted again, making it more stable when scraping excess glue on the surface of the fiberglass cloth tape 6.
