Description

Technical Field

[0001] This invention relates to the field of flexible circuit board lamination technology, and in particular to a vacuum hot press template assembly and a roll-type vacuum laminator for preventing adhesive buildup and reducing indentations. Prior Technology

[0002] After the insulating film or reinforcing material is adhered to the surface of the substrate of the flexible printed circuit (FPC), it needs to be heated and pressurized by a high-speed vacuum press to ensure that the insulating film or reinforcing material can be fully and tightly bonded to the copper foil of the substrate, so as to avoid the formation of bubbles or other defects that would cause scrap.

[0003] The vacuum laminator is equipped with a vacuum hot-pressing template assembly for laminating flexible circuit boards. The hot-pressing template assembly includes an upper laminator and a lower laminator. The upper laminator includes a rubber plate fixing plate, an airbag fixing plate, and an airbag. The airbag is fixed to the airbag fixing plate, and the airbag fixing plate is fixed to the rubber plate fixing plate. During the lamination operation, the upper and lower laminator templates close, and the airbag is inflated to apply downward pressure. The covering film on the copper foil surface is tightly pressed onto the copper foil surface by the adhesive on its inner surface, protecting the circuitry on the copper foil surface from oxidation and damage. However, the following technical problems also exist: 1. After the airbag is inflated and pressurized, the adhesive at the junction of the pressed and unpressed parts of the cover film on the substrate surface will be compressed and piled up in a linear manner—poor adhesive buildup, which will cause poor appearance and potential quality problems; 2. The unpressed portion of the product near the hot-pressing area of ​​the hot-pressing template is prematurely subjected to heat conduction from the mold cavity, causing a color change on the surface of the copper foil circuit after premature heating, resulting in an appearance color difference – a color defect. 3. The pressed part of the product softens due to high temperature and pressure, and is prone to deformation when pulled to the receiving side for the second time. Summary of the Invention

[0004] To solve the above-mentioned technical problems, an embodiment of the present invention provides a vacuum hot pressing template assembly for preventing glue buildup and reducing indentations, including an upper pressing template and a lower pressing template. The upper pressing template includes an upper heating plate, an airbag fixing plate, an airbag, a first upper cooling device, and a second upper cooling device. The lower surface of the upper heating plate includes a first cooling area, a middle hot pressing groove, and a second cooling area. The middle hot pressing groove is recessed between the first cooling area and the second cooling area. The first cooling area is located on the material inlet side of the middle hot pressing groove, and the second cooling area is located on the material receiving side of the middle hot pressing groove.

The airbag is fixed to the middle hot pressing groove by the airbag fixing plate. The lower pressing template includes a lower heating plate, a sintered iron plate, a first lower cooling device, and a second lower cooling device. The upper surface of the lower heating plate is provided with a groove, and the sintered iron plate is installed on the groove. Located below the sintered iron plate, the first lower cooling device and the second lower cooling device are respectively arranged in the lower heating plate corresponding to the first cooling area and the second cooling area.

[0005] Optionally, the first upper cooling device includes a plurality of first upper cooling pipes corresponding to the first cooling area, and a plurality of first upper mounting channels for installing the first upper cooling pipes are opened in the upper heating plate.

[0007] Optionally, the second upper cooling device includes a plurality of second upper cooling pipes corresponding to the second cooling area, and a plurality of second upper mounting channels for installing the second upper cooling pipes are opened in the upper heating plate.

[0008] Optionally, the second upper mounting channel is perpendicular to the product feeding direction within the vacuum hot press template group, and the second upper mounting channel passes through two corresponding sides of the upper heating plate.

[0009] Optionally, the first lower cooling device includes a plurality of first lower cooling pipes corresponding to the first cooling area, and a plurality of first lower mounting channels for installing the first cooling pipes are opened in the lower heating plate.

[0010] Optionally, the first lower mounting channel is perpendicular to the product feeding direction within the vacuum hot press template group, and the first lower mounting channel passes through two corresponding sides of the lower heating plate.

[0011] Optionally, the second lower cooling device includes a plurality of second lower cooling pipes corresponding to the second cooling area, and a plurality of second lower mounting channels for installing the second lower cooling pipes are opened in the lower heating plate.

[0012] Optionally, the second lower mounting channel is perpendicular to the product feeding direction within the vacuum hot press template group, and the second lower mounting channel passes through two corresponding sides of the lower heating plate.

[0013] Optionally, the upper pressing template further includes an upper sealing ring, which is fixed to the edge of the lower surface of the upper heating plate and is used to seal the mold cavity after the upper pressing template and the lower pressing template are closed.

[0014] Optionally, both the first cooling area and the second cooling area are provided with concave surfaces.

[0015] Optionally, in the product feeding direction within the vacuum hot press template group, the two concave surfaces respectively cover the first cooling area and the second cooling area; in the product feeding direction perpendicular to the vacuum hot press template group, the length of the concave surface is not less than the width of the product.

[0016] Optionally, the lower pressing template further includes a lower sealing ring, and the lower surface edge of the burnt iron plate is sealed to the lower heating plate through the lower sealing ring.

[0017] Another embodiment of the present invention provides a roll-type vacuum pressing machine, including the vacuum hot pressing template group described in the above embodiment.

[0018] Compared with the prior art, the technical solution of the embodiments of the present invention has the following beneficial effects: The vacuum hot pressing mold assembly for preventing glue buildup and reducing indentations provided by this invention adds an unpressed area and a pressed area to the existing vacuum hot pressing mold assembly, and adds cooling devices to the unpressed area and the pressed area respectively. During the pressing operation, the upper pressing mold and the lower pressing mold close together. The area corresponding to the intermediate hot pressing groove between the first cooling area and the second cooling area is the intermediate hot pressing area, which is at a high temperature. The area corresponding to the first cooling area on the material feeding side of the intermediate hot pressing area is the unpressed area, which is cooled to a low temperature by the first upper cooling device and the first lower cooling device. The area corresponding to the second cooling area on the material receiving side of the intermediate hot pressing area is the pressed area, which is also cooled to a low temperature by the second upper cooling device and the second lower cooling device. Because the unpressed area, intermediate hot-pressing area, and pressed area are arranged along the material feeding direction of the product (flexible printed circuit board) (the direction of movement from the infeed side to the receiving side is called the feeding direction), during the pressing operation, the product to be pressed first enters the unpressed area for cooling, then enters the intermediate hot-pressing area for high-pressure hot pressing, and finally enters the pressed area for cooling and shaping. Therefore, the adhesive inside the cover film on the surface of the product to be pressed is in a stable semi-cured state in the unpressed area within the vacuum hot-pressing template assembly. After entering the intermediate hot-pressing area for high-temperature hot pressing, the problem of adhesive buildup and indentation can be completely eliminated. Moreover, the product to be pressed first enters the unpressed area for cooling, so the copper foil circuit surface will not change color due to premature heating. Furthermore, the product after pressing enters the pressed area for cooling and shaping, preventing deformation during the secondary pulling towards the receiving side.

[0019] Furthermore, in the prior art, the upper and lower pressing molds directly compress the product surface during mold closing, causing premature compression and resulting in residual internal air and air bubbles. To solve the above technical problems, the present invention provides concave surfaces in both the first and second cooling areas, thereby reducing the direct pressure exerted on the product by the upper and lower pressing molds during mold closing.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Simple Explanation of the Diagram

[0024] Please refer to Figures 1 to 3. An embodiment of the present invention provides a vacuum hot-pressing template assembly for preventing glue buildup and reducing indentations, including an upper pressing template 1 and a lower pressing template 2. The upper pressing template 1 includes an upper heating plate 11, an airbag fixing plate 12, an airbag 13, a first upper cooling device 14, and a second upper cooling device 15. The lower surface of the upper heating plate 11 includes a first cooling area 111, a central hot-pressing groove 112, and a second cooling area 113. The central hot-pressing groove 112 is recessed between the first cooling area 111 and the second cooling area 113. The first cooling area 111 is located on the material inlet side of the central hot-pressing groove 112, and the second cooling area 113 is located on the material receiving side of the central hot-pressing groove 112. The first upper cooling device 14 and the second upper cooling device 15 are respectively disposed within the upper heating plate 11 corresponding to the first cooling area 111 and the second cooling area 113. The airbag 13 is connected to the airbag fixing plate 12. It is fixed in the intermediate hot-pressed groove 112.

[0025] The lower pressing template 2 includes a lower heating plate 21, a sintered iron plate 24, a first lower cooling device 22, and a second lower cooling device 23. The upper surface of the lower heating plate 21 is provided with a groove 211, and the sintered iron plate 24 is installed in the groove 211. The first lower cooling device 22 and the second lower cooling device 23 are respectively located below the sintered iron plate 24 and are arranged in the lower heating plate 21, corresponding to the first cooling area 111 and the second cooling area 113.

[0026] An embodiment of the present invention provides a vacuum hot-pressing template assembly for preventing glue buildup and reducing indentations. Based on existing vacuum hot-pressing template assemblies, it adds an unpressed area and a pressed area, and adds cooling devices to both areas. During the pressing operation, the upper pressing template 1 and the lower pressing template 2 close. The area corresponding to the intermediate hot-pressing groove 112 located between the first cooling area 111 and the second cooling area 113 is the intermediate hot-pressing area, which is at a high temperature. The area corresponding to the first cooling area 111 on the material inlet side of the intermediate hot-pressing area is the unpressed area, which is cooled by the first upper cooling device 14 and the first lower cooling device 22 to a low temperature. The area corresponding to the second cooling area 113 on the material receiving side of the intermediate hot-pressing area is the pressed area, which is cooled by the second upper cooling device 15 and the second lower cooling device 23 to a low temperature.

[0027] Since the unpressed area, intermediate hot-pressing area, and pressed area are set along the material feeding direction of the product (flexible printed circuit board) (the direction of movement from the feeding side to the receiving side is called the feeding direction), during the pressing operation, the product to be pressed first enters the unpressed area for cooling, then enters the intermediate hot-pressing area for high-pressure hot pressing, and finally enters the pressed area for cooling and shaping. Therefore, the adhesive inside the cover film on the surface of the product to be pressed is in a stable semi-cured state in the unpressed area of ​​the vacuum hot-pressing template group, and then enters the intermediate hot-pressing area for high-temperature hot pressing, which can completely eliminate the problem of adhesive buildup and reduce indentation.

[0028] Moreover, the product to be pressed first enters the unpressed area for cooling, so that the copper foil circuit surface will not change color due to premature heating.

[0029] Furthermore, after the product is pressed, it enters the pressed area for cooling and shaping to prevent deformation when it is pulled towards the receiving side for the second time.

[0030] In this embodiment, the lower surface edge of the sintered iron plate 24 is also sealed to the lower heating plate 21 by a lower sealing ring 25. The lower surface of the upper heating plate 11 includes a first cooling region 111, an intermediate hot-pressing groove 112, and a second cooling region 113. Therefore, the upper surface of the sintered iron plate 24 also includes a first lower cooling region, an intermediate hot-pressing region, and a second lower cold region, which correspond one-to-one with the first cooling region 111, the intermediate hot-pressing groove 112, and the second cooling region 113, respectively. An unpressed region is formed between the first cooling region 111 and the first lower cooling region, an intermediate hot-pressing region is formed between the intermediate hot-pressing groove 112 and the intermediate hot-pressing region, and a pressed region is formed between the second cooling region 113 and the second lower cold region.

[0031] This embodiment does not limit the specific structure of the first upper cooling device 14, as long as it can cool the first cooling area 111. For example, the first upper cooling device 14 may include a cooling channel or cooling pipe opened in the upper heating plate 11 corresponding to the first cooling area 111.

[0032] To facilitate pipe connection between the first upper cooling device 14 and an external chiller, in one embodiment, the upper heating plate 11 is a solid plate structure with a certain thickness. The first upper cooling device 14 includes several first upper cooling pipes corresponding to the first cooling area 111. Several first upper mounting channels for installing the first upper cooling pipes are formed within the upper heating plate 11. The first upper mounting channels are perpendicular to the product feeding direction within the vacuum hot pressing template assembly and penetrate through two corresponding sides of the upper heating plate 11. The several first upper cooling pipes are respectively installed through the several first upper mounting channels.

[0033] The first upper cooling pipe has a first upper interface at both ends for pipe connection. In this embodiment, the number of first upper cooling pipes is not limited and can be set according to the actual size of the first cooling area 111 and the required cooling capacity.

[0034] The first upper cooling pipes can be arranged in series or in parallel; this embodiment does not impose any restrictions on this.

[0038] The multiple second upper cooling pipes can be arranged in series or in parallel; this embodiment does not impose any restrictions on this.

[0039] This embodiment does not limit the specific structure of the first lower cooling device 22, as long as it can cool the portion of the sintered iron plate 24 corresponding to the first cooling area 111. Cooling the portion of the sintered iron plate 24 corresponding to the first cooling area 111 achieves the cooling of the unpressed area after mold closing. The first lower cooling device 22 can be a cooling channel or cooling pipe, etc., opened in the lower heating plate 21 corresponding to the first cooling area 111.

[0040] To facilitate pipe connection between the first lower cooling device 22 and an external chiller, in one embodiment, the lower heating plate 21 is a solid plate structure with a certain thickness. The first lower cooling device 22 includes several first lower cooling pipes corresponding to the first cooling area 111. Several first lower mounting channels for installing the first lower cooling pipes are formed within the lower heating plate 21. The first lower mounting channels are perpendicular to the product feeding direction within the vacuum hot pressing template assembly and penetrate through two corresponding sides of the lower heating plate 21. The several first lower cooling pipes are respectively installed through the several first lower mounting channels.

[0041] The first lower cooling pipe has a first lower interface at both ends for pipe connection. In this embodiment, the number of first lower cooling pipes is not limited and can be set according to the actual size of the first cooling area 111 and the required cooling capacity.

[0042] The first cooling pipes can be connected in series or in parallel; this embodiment does not impose any restrictions on this.

[0043] This embodiment does not limit the specific structure of the second lower cooling device 23, as long as it can cool the portion of the sintered iron plate 24 corresponding to the second cooling area 113. Cooling the portion of the sintered iron plate 24 corresponding to the second cooling area 113 achieves the cooling of the pressed area after mold closing. The second lower cooling device 23 can be a cooling channel or cooling pipe, etc., opened in the lower heating plate 21 corresponding to the second cooling area 113.

[0044] To facilitate pipe connection between the second lower cooling device 23 and an external chiller, in one embodiment, the lower heating plate 21 is a solid plate structure with a certain thickness. The second lower cooling device 23 includes several second lower cooling pipes corresponding to the second cooling area 113. Several second lower mounting channels for installing the second lower cooling pipes are formed within the lower heating plate 21. The second lower mounting channels are perpendicular to the product feeding direction within the vacuum hot pressing template assembly and penetrate through two corresponding sides of the lower heating plate 21. The several second lower cooling pipes are respectively installed through the several second lower mounting channels.

[0045] The second lower cooling pipe has a second lower interface at both ends for pipe connection. In this embodiment, the number of second lower cooling pipes is not limited and can be set according to the actual size of the second cooling zone 113 and the required cooling capacity.

[0046] The secondary cooling pipes can be connected in series or in parallel; this embodiment does not impose any restrictions on this.

[0047] In order to seal the mold cavity after the upper pressing template 1 and the lower pressing template 2 are closed, as an example, the upper pressing template 1 further includes an upper sealing ring 16, which is fixed to the edge of the lower surface of the upper heating plate 11.

[0048] In the prior art, when the upper pressing template 1 and the lower pressing template 2 are closed, they directly compress the surface of the product, causing the product to be compressed in advance, resulting in residual internal air and the formation of air bubbles.

[0049] To solve the above-mentioned technical problems, in one embodiment of the present invention, a first concave surface 1111 is provided on the first cooling region 111, and a second concave surface 1131 is provided on the second cooling region 113. Therefore, the direct pressure of the upper pressing template 1 and the lower pressing template 2 on the product can be reduced.

[0050] To further reduce the direct pressure exerted on the product by the upper pressing mold 1 and the lower pressing mold 2 during mold closing, in the product feeding direction within the vacuum hot pressing mold assembly, the first concave surface 1111 completely covers the first cooling area 111, and the second concave surface 1131 completely covers the second cooling area 113. In the product feeding direction perpendicular to the vacuum hot pressing mold assembly, the first concave surface 1111 may or may not completely cover the first cooling area 111; the second concave surface 1131 may or may not completely cover the second cooling area 113. To ensure that the product is located within the first concave surface 1111 and the second concave surface 1131 in the product feeding direction perpendicular to the vacuum hot pressing mold assembly, the lengths of both the first concave surface 1111 and the second concave surface 1131 are not less than the width of the product, thereby reducing the compression of the substrate in the length direction by the upper pressing mold 1 and the lower pressing mold 2 during mold closing.

[0051] To further reduce the compression of the product width direction by the closing of the upper pressing template 1 and the lower pressing template 2, the edge of the first cooling area 111 furthest from the middle hot pressing groove 112 is flush with the side of the upper hot plate 11 on the feeding side, and the edge of the second cooling area 113 furthest from the middle hot pressing groove 112 is flush with the side of the upper hot plate 11 on the receiving side.

[0052] As one embodiment, the lower surface edge of the upper heating plate 11 is provided with an annular groove for mounting the upper sealing ring 16, and the lower end of the upper sealing ring 16 protrudes out of the annular groove.

[0053] To prevent air leakage from the mold cavity when the upper pressing mold plate 1 and the lower pressing mold plate 2 are closed, the bottom of the annular groove is located above the first concave surface 1111 and the second concave surface 1131, or flush with the first concave surface 1111 and the second concave surface 1131, in order to prevent air leakage from the first concave surface 1111 and the second concave surface 1131 when the mold is closed.
