Description

Technical Field

[0001] The invention relates to a hot pressing processing technology, and in particular to a hot pressing curing processing device and method for preparing an epoxy glass fiber cloth-based steel foil-clad plate. Background Art

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

[0003] At present, for the preparation of epoxy glass fiber cloth-based steel foil-covered board, it is necessary to first process the glass fiber yarn through processes such as impregnation, drying, and curling to make a glass fiber cloth with certain strength and flexibility, and then impregnate the glass fiber cloth in epoxy resin, and combine it with the epoxy resin through processes such as drying and curing. At the same time, high-quality steel is made into a steel foil with uniform thickness and smooth surface through processes such as shearing and stamping, and then the processed steel foil is covered on the surface of the epoxy glass fiber cloth. Through processes such as hot pressing and bonding, the steel foil and the epoxy glass fiber cloth are combined into one to form an epoxy glass fiber cloth-based steel foil-covered board.

[0004] When the steel foil and epoxy glass fiber cloth are hot-pressed during the bonding process, bubbles may exist in the bonding surface of the steel foil and the epoxy glass fiber cloth due to the placement. The existence of bubbles will lead to insufficient bonding between the steel foil and the epoxy glass fiber cloth, which will not only reduce its strength but also its durability. Therefore, the bubbles need to be cleaned before processing. The common cleaning method is to use a large steel plate to directly press the entire steel plate. When the large steel plate is in contact with the surface of the epoxy glass fiber cloth at the same time, the gas inside it lacks a discharge channel, resulting in the inability to discharge, so that some bubbles still remain in the bonding surface.

[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] Embodiment 1:

[0042] See also Figure 1-Figure 6 , a hot pressing curing treatment device for preparing epoxy glass fiber cloth-based steel foil-covered board, comprising a workbench 1, an upper pressing plate 2 and a lower pressing plate 3, and also comprising:

[0043] There are two connecting plates 5, which are symmetrically fixedly connected to both sides of the upper pressing plate 2;

[0044] The pretreatment mechanism 4 includes support blocks 41 symmetrically fixedly connected to the two ends of the side of the connecting plate 5, a support plate 42 is arranged outside the support block 41, a support groove 43 corresponding to the support block 41 is provided on the surface of the support plate 42, a vertical plate 44 is fixedly connected to the bottom of the support plate 42, a horizontal plate 45 is fixedly connected to the bottom of the vertical plate 44, a horizontal groove 46 is provided on the side of the horizontal plate 45 close to the upper pressing plate 2, a connecting block 47 is slidably connected to the inner side of the horizontal groove 46, a rotating roller 48 is rotatably connected to the outside of the connecting block 47, and a driving component 49 is provided between the horizontal plate 45 and the vertical plate 44;

[0045] The driving assembly 49 is used to drive the rotating roller 48 to move along the length direction of the transverse groove 46 .

[0046] In this embodiment, the bottom opening of the support groove 43 is set, and the shape and size specifications of the support groove 43 are compatible with the support block 41, the length of the rotating roller 48 is greater than the width of the lower pressure plate 3, and the length of the transverse groove 46 is greater than the length of the lower pressure plate 3.

[0047] Specifically, through the mutual cooperation between the two support blocks 41 and the support grooves 43, the support plate 42 and several structures arranged at the bottom thereof can be stably supported in a non-hot pressing working state. At the same time, when the connecting plate 5 needs to continue to move downward, its movement will not be hindered.

[0048] Furthermore, when the rotating roller 48 moves to remove bubbles, its width and travel distance can achieve complete coverage of the steel foil plate to be processed, so that the bubbles can be fully discharged.

[0049] In this embodiment, the driving component 49 includes a vertical groove 491 opened on the surface of the vertical plate 44, a rectangular slider 492 is fixedly connected to the side of the connecting plate 5, and a plurality of wire wheels 493 are respectively installed on the top of the support plate 42 and the top of the horizontal plate 45 away from the connecting block 47. A first wire groove 494 connected to the horizontal groove 46 is opened on the side of the horizontal plate 45 away from the connecting block 47. One end of the first traction rope 495 is fixedly connected to the top surface of the rectangular slider 492, and the other end of the first traction rope 495 is slidably connected to the surface of the wire wheels 493 in sequence along the distribution direction of the plurality of wire wheels 493, and passes through the first wire groove 494 to be fixedly connected to the connecting block 47.

[0050] In this embodiment, the rectangular slider 492 is slidably connected to the inner side surface of the vertical groove 491. When the rectangular slider 492 moves downward along the inner wall of the vertical groove 491 to pull one end of the first traction rope 495, the other end of the first traction rope 495 can drive the connecting block 47 to move along the inner wall of the horizontal groove 46.

[0051] In this embodiment, a spring groove 496 is provided inside the transverse plate 45, and a return spring 497 is fixedly connected to the end of the inner wall of the spring groove 496 close to the connecting block 47, and a moving block 498 is fixedly connected to the end of the return spring 497 away from the connecting block 47. A second traction rope 499 is fixedly connected between the moving block 498 and the connecting block 47, and a second wire groove 4910 is provided between the transverse groove 46 close to one end of the connecting block 47 and the spring groove 496. A plurality of positioning blocks 4911 are fixedly connected to the bottom of the transverse plate 45, and a fixing strip 4912 corresponding to the transverse plate 45 is fixedly connected to the surface of the workbench 1, and a positioning groove 4913 corresponding to the positioning block 4911 is provided on the surface of the fixing strip 4912.

[0052] In this embodiment, the second traction rope 499 is slidably connected to the inner side surface of the second wire groove 4910, so that when one end of the second traction rope 499 is pulled, the other end thereof can be stably transmitted.

[0053] When in use, the upper pressing plate 2 moves downward, driving the connecting plate 5 to move downward synchronously, so that the supporting plate 42 moves downward, and drives the vertical plate 44 and the horizontal plate 45 to move downward synchronously. When the positioning block 4911 at the bottom of the horizontal plate 45 moves into the positioning groove 4913, the horizontal plate 45 cannot continue to move downward. At this time, as the connecting plate 5 continues to move downward, the rectangular sliding block 492 will slide downward along the inner wall of the vertical groove 491 and pull one end of the first traction rope 495. Under the guiding action of several wire wheels 493, the other end of the first traction rope 495 drives the connecting block 47 to slide along the inner wall of the horizontal groove 46. When the connecting block 47 moves, it drives the rotating roller 48 to move. During the movement, the rotating roller 48 contacts the surface of the epoxy glass fiber cloth, so that under the friction between the two, the rotating roller 48 will rotate synchronously during the movement, so that the bubbles between the epoxy glass fiber cloth and the steel foil plate can be fully removed, so that the hot pressing effect between the two is better.

[0054] When the connecting block 47 moves, it will also pull one end of the second traction rope 499, so that the other end of the connecting block 497 drives the moving block 498 to move. When the moving block 498 moves, it will compress the reset spring 497, so that when the first traction rope 495 is no longer actively pulled by external force, the connecting block 47 can automatically reset under the action of the rebound force of the reset spring 497.

[0055] Embodiment 2:

[0056] See also Figure 7-Figure 9 This embodiment provides a technical solution based on the above embodiment: it also includes:

[0057] The adjusting mechanism 6 includes a mounting plate 61 fixedly connected to the outside of the connecting block 47, an adjusting groove 62 is provided on the surface of the mounting plate 61, an adjusting block 63 and a mounting block 64 are slidably connected in sequence from top to bottom inside the adjusting groove 62, a screw 65 is rotatably connected to the inner side of the adjusting groove 62, an adjusting spring 66 is fixedly connected between the adjusting block 63 and the mounting block 64, the adjusting block 63 is threadedly connected to the screw 65, a through groove is provided on the surface of the mounting block 64, the through groove is coaxially arranged with the screw 65 and the adjusting spring 66, and the groove diameter value of the through groove and the inner diameter value of the adjusting spring 66 are both greater than the outer diameter value of the screw 65.

[0058] In this embodiment, the outside of the screw rods 65 on both sides are fixedly connected with pulleys 67, and a transmission belt 68 is transmission-connected between the two pulleys 67. A long plate 69 is fixedly connected between the tops of the two mounting plates 61. The inner side surface of the long plate 69 is rotationally connected with a worm 610. The outer end of the worm 610 is fixedly connected with a handwheel 611, and the outside of the worm 610 is meshed with a worm wheel 612.

[0060] When the pressure of the rotating roller 48 during operation needs to be adjusted before hot pressing, the operator manually turns the hand wheel 611. The rotation of the hand wheel 611 drives the worm 610 to rotate. The rotation of the worm 610 drives the worm wheel 612 to rotate. The rotation of the worm wheel 612 drives a screw 65 to rotate. With the cooperation between the two pulleys 67 and the transmission belt 68, the screws 65 on both sides can rotate synchronously. When the screw 65 rotates, it drives the adjustment block 63 to move in the vertical direction, so that it can move relative to or synchronously with the mounting block 64, so that the initial state of the adjustment spring 66 or the initial position of the mounting block 64 can be adjusted, so that the contact pressure when the rotating roller 48 moves downward and contacts the epoxy glass fiber cloth can be adjusted as needed.
