[0029] As described in the background technology, the existing pressing equipment for pressing the tape-type FPC (flexible circuit board) to be pressed supports the lower pressing template through an oil cylinder. The load-bearing capacity of the oil cylinder is limited. Therefore, when the airbag is inflated, the air pressure in the airbag will press down the lower pressing template. Due to the insufficient load-bearing capacity of the oil cylinder, the lower pressing template descends with the piston rod of the oil cylinder, and then separates from the upper pressing template, resulting in the inability to perform the pressing operation.
[0030] In order to solve the above technical problems, the utility model provides a roll-type vacuum hot pressing equipment, please refer to Figures 1 to 4, used to press the flexible circuit board 2 to be pressed; it includes an upper pressing template 104, a lower pressing template 105, a lifting mechanism 110 and at least two support mechanisms 109 located on both sides of the lifting mechanism 110, the upper pressing template 104 is located above the lower pressing template 105, and the lifting structure is located below the lower pressing template 105; the support mechanism 109 includes a horizontal pushing drive device 10901 and a horizontally movable support block 10906, the horizontal pushing drive device 10901 is driven and connected to the horizontally movable support block 10906, during the pressing operation, the lower pressing template 105 is lifted by the lifting mechanism 110 to be molded with the upper pressing template 104; the horizontally movable support block 10906 is pushed by the horizontal pushing drive device 10901 to move horizontally to the bottom of the lower pressing template 105 to support the lower pressing template 105.
[0031] During the pressing operation, the utility model supports the lower pressing template 105 by means of the horizontally movable support block 10906. Since the horizontally movable support block 10906 can only move horizontally and cannot move vertically, the horizontally movable support block 10906 can provide sufficient vertical supporting force to support the lower pressing template 105, thereby preventing the lower pressing template 105 from being separated from the upper pressing template 104 during the inflation of the vacuum air bag, thereby solving the above-mentioned technical problems and ensuring the reliability of the pressing operation.
[0032] Specifically, during the pressing operation, first, the lower pressing template 105 is lifted by the lifting mechanism 110 and is pressed together with the upper pressing template 104; then, the horizontally movable support block 10906 is pushed horizontally to the bottom of the lower pressing template 105 by the horizontal pushing drive device 10901 to support the lower pressing template 105.
[0033] After the pressing operation is completed, first, the horizontally movable support block 10906 is withdrawn through the horizontal pushing drive device 10901 and separated from the lower pressing template 105, and then the lower pressing template 105 is driven to descend through the lifting mechanism 110.
[0034] In order to make the above-mentioned purposes, features and beneficial effects of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0035] Please refer to Figures 1 to 4 One embodiment of the present invention provides a roll-to-roll vacuum hot pressing apparatus for laminating a flexible circuit board 2 to be laminated. In this embodiment, the flexible circuit board 2 to be laminated has a cover film laminated onto the copper foil. Therefore, the vacuum hot pressing apparatus provided in this embodiment performs the laminating operation on the copper foil laminated with the cover film.
[0036] The vacuum hot pressing equipment provided in this embodiment includes a vacuum hot pressing body 1, the vacuum hot pressing body 1 includes an equipment frame and an upper pressing template 104, a lower pressing template 105, a lifting mechanism 110 and at least two supporting mechanisms 109 located on both sides of the lifting mechanism 110, the equipment frame includes a first side plate 111 and a second side plate 112 arranged at intervals, the upper pressing template 104 is fixedly arranged between the first side plate 111 and the second side plate 112; the lower pressing template 105 is arranged on the upper pressing template 104. The lower surface of the lower pressing plate 105 is fixed to the upper surface of the pressing plate 108, and the pressing plate 108 is movably arranged between the first side plate 111 and the second side plate 112, that is, the pressing plate 108 is not fixed to the first side plate 111 and the second side plate 112. Therefore, the pressing plate 108 can be raised and lowered by the lifting mechanism 110 below it, and then the pressing plate 108 can drive the lower pressing plate 105 to rise and fall. Therefore, the lower pressing plate 105 and the pressing plate 108 are movably arranged between the first side plate 111 and the second side plate 112.
[0037] The support mechanism 109 includes a horizontal pushing drive device 10901 and a horizontal moving support block 10906 , and the horizontal pushing drive device 10901 is drivingly connected to the horizontal moving support block 10906 .
[0038] During the pressing operation, first, the lower pressing plate 105 is lifted along with the pressure bearing plate 108 by the lifting mechanism 110, so that the lower pressing plate 105 is pressed together with the upper pressing plate 105; then, the horizontally movable support block 10906 is pushed by the horizontal driving device 10901 to move horizontally to the bottom of the pressure bearing plate 108, supporting the pressure bearing plate 108 and further supporting the lower pressing plate 105. Since the horizontally movable support block 10906 can only move horizontally and cannot move vertically, it can provide sufficient vertical support force to support the lower pressing plate 105, preventing the lower pressing plate 105 from separating from the upper pressing plate 104 during the vacuum bag inflation process, thereby ensuring the reliability of the pressing operation.
[0039] After the pressing operation is completed, first, the horizontally movable support block 10906 is retracted through the horizontal pushing drive device 10901 and disengaged from the pressure bearing plate 108. Therefore, the horizontally movable support block 10906 is no longer located below the pressure bearing plate 108, and then the lower pressing template 105 follows the pressure bearing plate 108 and descends together with the lifting mechanism 110.
[0040] Since the lifting and lowering of the lifting mechanism 110 drives the pressure bearing plate 108 and the lower pressing template 105 to rise and fall, which is a mature technology in this field, the present invention does not limit the specific type of the lifting mechanism 110. For example, it can be an electric cylinder, a pneumatic cylinder or an oil cylinder. As an embodiment, the lifting mechanism 110 is a lifting cylinder.
[0041] The present invention does not limit the specific type of the horizontal pushing drive device 10901. For example, it can be an electric cylinder, a pneumatic cylinder, or an oil cylinder. As an embodiment, the horizontal pushing drive device 10901 is a horizontal pushing cylinder.
[0042] As an embodiment, the support mechanism 109 also includes a base 10903 and at least one horizontal support shaft 10904, the two ends of the horizontal support shaft 10904 are horizontally fixed on the base 10903 through a support pad 10902, and the horizontal movable support block 10906 is slidably set on the horizontal support shaft 10904.
[0043] This embodiment does not limit the number of horizontal support shafts 10904. In order to ensure the stability of the horizontal movement of the horizontally movable support block 10906, in a specific embodiment, the support mechanism 109 includes two horizontal support shafts 10904, and the two horizontal support shafts 10904 are arranged in parallel. Two mounting holes are set on the horizontally movable support block 10906, and the two horizontal support shafts 10904 are movable through the two mounting holes respectively.
[0044] During the mold closing operation, in order to adjust the gap between the horizontally movable support block 10906 and the pressure bearing plate 108 so that the horizontally movable support block 10906 can contact the pressure bearing plate 108, a fine-tuning stud 10905 is also longitudinally provided on the top of the horizontally movable support block 10906. By loosening or tightening the fine-tuning stud 10905, the height of the fine-tuning stud 10905 on the top of the horizontally movable support block 10906 can be changed, so that it can contact the pressure bearing plate 108, thereby preventing the lower pressing template 105 from loosening and leaking vacuum, thereby ensuring the reliability of the pressing operation.
[0045] Since the upper pressing template 104 and the lower pressing template 105 are mature technologies in this field, the present invention does not limit the specific structures of the upper pressing template 104 and the lower pressing template 105.
[0046] Please refer to Figure 5 As an embodiment, the upper pressing template 105 includes a rubber plate fixing plate 10401, an airbag fixing plate 10403, a vacuum air bag 10404 and an upper sealing ring 10402. The vacuum air bag 10404 is fixed to the lower surface of the rubber plate fixing plate 10401 through the airbag fixing plate 10403, that is, the airbag fixing plate 10403 is fixed to the lower surface of the rubber plate fixing plate 10401, and the vacuum air bag 10404 is fixed to the lower surface of the airbag fixing plate 10403; the upper sealing ring 10402 is located at the outer periphery of the lower surface of the rubber plate fixing plate 10401.
[0047] The area of the rubber plate fixing plate 10401 is larger than the area of the airbag fixing plate 10403 , and an escape space of matching size for wrapping the vacuum airbag 10404 and the airbag fixing plate 10403 is provided in the rubber plate fixing plate 10401 .
[0048] In a specific embodiment, a closed groove is provided on the outer periphery of the lower surface of the rubber plate fixing plate 10401 , and the upper sealing ring 10402 is embedded in the groove.
[0049] The rubber plate fixing plate 10401 is provided with a first inflation hole, the airbag fixing plate 10403 is provided with a second inflation hole connected to the first inflation hole, the second inflation hole is communicated with the vacuum air bag 10404, and the vacuum air bag 10404 is inflated and deflated through the first inflation hole and the second inflation hole.
[0050] Please refer to Figure 6The lower pressing template 105 includes a lower hot plate 10501, a fired iron plate 10504, a lower sealing ring 10502, and several spacers 10503. A recess is provided in the middle of the upper surface of the lower hot plate 10501. The lower sealing ring 10502 is located below the fired iron plate 10504. The fired iron plate 10504 is sealed in the recess by the lower sealing ring 10502, and the upper surface of the fired iron plate 10504 is flush with the upper surface of the lower hot plate 10501. Because the fired iron plate 10504 is located in the recess of the lower hot plate 10501, the area of the lower hot plate 10501 is larger than that of the fired iron plate 10504, and the area of the fired iron plate 10504 is also larger than that of the vacuum air bag 10404. The several spacers 10503 are distributed around the circumference of the upper surface of the lower hot plate 10501. The lower heating plate 10501 is provided with a first air guide channel, and the sintering iron plate 10504 is provided with a second air guide channel connected to the first air guide channel. The mold cavity formed after the upper pressing template 104 and the lower pressing template 105 are closed by the first air guide channel and the second air guide channel is vacuumed and broken.
[0051] Among them, the pad 10503 is used to raise the internal space of the mold cavity after the upper pressing template 104 and the lower pressing template 105 are closed, so that there is a certain gap between the two templates to ensure that the upper sealing ring 10402 of the upper pressing template 104 and the upper surface of the lower pressing template 105 are in contact and limited, ensuring that the planes of the four surfaces of the product are moderately close.
[0052] In the above scheme, by arranging a vacuum air bag 10404 in the structure of the upper pressing template 104, it is achieved that during the pressing process, the upper pressing template 104 can adopt a soft landing structure to apply pressure between the flexible circuit board on the upper surface of the fired iron plate 10504 of the lower pressing template 105, thereby avoiding deformation or poor indentation of the left and right ends of the flexible circuit board in the pressing template during the pressing operation; and a number of pads 10503 are arranged on the surface of the lower pressing template 105, which are raised by overlapping and protruding, thereby further reducing the squeezing force of the upper sealing ring 10402 on the surface of the upper pressing template 104 on the flexible circuit board.
[0053] In addition, a lower sealing ring 10502 is designed at the bottom of the fired iron plate 10504 in the lower pressing template 105, which can achieve a sealing effect around the fired iron plate 10504 after the upper pressing template 104 and the lower pressing template 105 are molded, so that the vacuum degree in the mold cavity after the upper and lower pressing templates are molded meets the standard and there is no problem of air pressure leakage; and the area of the lower hot plate 10501 in the lower pressing template 105 is larger than the area of the fired iron plate 10504, which avoids the problem that the four edges of the vacuum air bag 10404 are squeezed into the edge gap between the fired iron plate 10504 and the lower hot plate 10501 during the pressing operation, causing damage to the air bag, thereby further increasing the safety of the pressing operation.
[0054] In one embodiment, a limit sensor is provided on the lower surface of the lower heating plate 10501, and the lifting mechanism 110 receives the limit position signal of the lower heating plate 10501 through the limit sensor, transmits the signal to the PLC, and then gives an instruction to drive the horizontal sliding support block.
[0055] In a specific embodiment, the limit sensor is used to transmit the position signal data of the rising lower pressing template 105 to the lifting mechanism 110 to control the lifting stroke of the lifting mechanism 110, thereby controlling the distance between the lower pressing template 105 and the upper pressing template 104.
[0056] In one embodiment, the roll-to-roll pressing equipment also includes a top plate 101, an upper insulation plate 102, an upper heating plate 103, a lower insulation plate 107 and a lower heating plate 106. The top plate 101 is fixed to the upper ends of the first side plate 111 and the second side plate 112. The upper insulation plate 102 and the upper heating plate 103 are arranged in sequence from top to bottom between the upper surface of the rubber plate fixing plate 10401 and the lower surface of the top plate 101. The lower heating plate 106 and the lower insulation plate 107 are arranged in sequence from top to bottom between the lower surface of the lower heat plate 10501 and the upper surface of the pressure bearing plate 108.
[0057] In one example, the upper insulation board 102 and the lower insulation board 107 include fiberglass boards or epoxy resin boards.
[0058] Of course, the present invention is not limited to this, and other materials that can achieve thermal insulation effects are within the protection scope of the present invention.
[0059] In one embodiment, the roll-to-roll vacuum hot pressing equipment further includes a feeding end 3 and a receiving end 4 , and the feeding end 3 and the receiving end 4 are respectively located on both sides of the vacuum hot pressing body 1 .
[0060] Please refer to Figure 7As an embodiment, the feed end 3 is located on the left side of the vacuum hot pressing body 1 and includes a flexible circuit board reel 301 for pressing, an upper surface auxiliary material reel 306, a lower surface auxiliary material reel 302, a dust-binding device 303 for the flexible circuit board to be pressed, an auxiliary material dust-binding device 305, a docking device 304, a material tape sensing device, a pull-back device 307, and a cooling mechanism 308. The flexible circuit board 2 to be pressed is wound on the flexible circuit board reel 301, the upper surface auxiliary material is wound on the upper surface auxiliary material reel 306, and the lower surface auxiliary material is wound on the lower surface auxiliary material reel 302. During the pressing operation, the upper surface auxiliary material is attached to the upper surface of the flexible circuit board 2 to be pressed, and the lower surface auxiliary material is attached to the lower surface of the flexible circuit board 2 to be pressed. The auxiliary materials serve as a release barrier. Because high temperatures are generated during the pressing process, and the upper and lower pressing templates are both made of silicone material, this material will produce silicone oil under high temperature and high pressure, which may cause surface contamination of the product.
[0061] The upper surface auxiliary materials and the lower surface auxiliary materials can be release films or TPX. If it is TPX, it also needs to be combined with fiberglass cloth, that is, the upper surface of the upper surface auxiliary material needs to be attached with another layer of upper surface auxiliary material, and the lower surface of the lower surface auxiliary material needs to be attached with another layer of lower surface auxiliary material.
[0062] The dust-binding device 303 for the flexible circuit board to be pressed is mainly used to bind impurities on the surface of the flexible circuit board 2 to be pressed, so as to prevent foreign matter and impurities from crushing the product; the auxiliary material dust-binding device 305 is mainly used to bind impurities on the surface of the auxiliary material, so as to prevent foreign matter and impurities from crushing the product.
[0063] The docking device 304 is mainly used to connect the previous roll and the next roll of flexible circuit boards 2 to be pressed, or to connect the broken materials, so as to achieve continuous and uninterrupted production of the rolls.
[0064] The material strip sensing device is mainly used to determine whether the flexible circuit board 2 to be pressed is broken. If it is broken, it will send a signal and issue an alarm to request a solution.
[0065] During docking, the coiled material at the receiving end 4 is under tension, and simply pulling the flexible circuit board back to the docking device 304 will not pull it. Therefore, a pull-back device 307 is required. Pull-back device 307 is equipped with a pressure plate that is raised and lowered by a pneumatic cylinder. When the material is cut off, the cylinder controls the pressure plate to press down on the flexible circuit board to be pressed. This prevents the flexible circuit board from being conveyed further to the receiving end 4, facilitating docking. Simultaneously, the pressure plate also presses down on the auxiliary materials, preventing them from being conveyed further to the receiving end 4, thus preventing waste.
[0066] The cooling mechanism 308 is used to cool the unpressed flexible circuit board. Because the high temperature of the hot pressing body 1 causes the flexible circuit board 2 to be pressed on the left to be oxidized and scrapped, the cooling mechanism 308 uses the circulating water in the ice water machine to flow closedly into the cooling plate on the left side of the hot pressing body 1, thereby physically cooling the temperature. The cooling plate is just clamped on the upper and lower surfaces of the flexible circuit board 2 to be pressed, so that the low temperature of the cooling plate can be used to cool the product temperature at the feed point to be pressed.
[0067] The receiving end 4 includes a separation device 401, a pulling mechanism 402, a reel 403 for the pressed product, an upper surface auxiliary material receiving reel 405 and a lower surface auxiliary material receiving reel 404. The separation device 401 is arranged on the right side of the hot pressing body 1, and is used to separate the pressed flexible circuit board from the upper surface auxiliary material and the lower surface auxiliary material. The separated pressed flexible circuit board, upper surface auxiliary material and lower surface auxiliary material are tightened by the pulling mechanism 402 and are respectively wound on the reel 403 for the pressed product, the upper surface auxiliary material receiving reel 405 and the lower surface auxiliary material receiving reel 404.
[0068] The utility model also provides a roll-to-roll vacuum hot pressing process, comprising the following steps:
[0069] Feeding the flexible circuit board to be pressed between the upper pressing template 104 and the lower pressing template 105;
[0070] The lifting mechanism 110 rises and lifts the lower pressing plate 105 to close the mold with the upper pressing plate 104;
[0071] Vacuuming the mold cavity formed by the lower pressing template 105 and the upper pressing template 104;
[0072] The horizontal driving device 10901 drives the horizontal moving support block 10906 to move horizontally to the bottom of the lower pressing template 105 and supports the lower pressing template 105;
[0073] The lifting mechanism 110 descends;
[0074] Inflate the vacuum air bag 10404 in the upper pressing template 104, and use the pressure after inflation to press the flexible circuit board to be pressed;
