Description

Technical Field

[0001] This application relates to the field of FPC protective film lamination technology, and in particular to an FPC protective film lamination fixture. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable printed circuit boards characterized by high wiring density, light weight, thinness, and good bendability. In FPC manufacturing, the application and lamination of the protective film is a critical process that directly affects the product's reliability and lifespan. Traditionally, the protective film is bonded to the FPC copper plate via hot pressing, requiring a lamination fixture for the protective film.

[0003] The pressing fixture typically uses an upper mold and a lower mold pressing method. Generally, both the upper and lower molds use high-temperature fiberglass cloth as the pressing medium, and the protective film is bonded to the FPC through hot pressing. However, high-temperature fiberglass cloth is prone to wear after long-term use and needs to be replaced frequently. In order to ensure accurate pressing position, guide pillars are generally used to make the pressing position of the upper and lower molds stable. Once replaced, the upper mold, lower mold and several guide pillars need to be disassembled as a whole, which is troublesome and has poor installation efficiency. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an FPC protective film pressing fixture.

[0005] The FPC protective film pressing fixture provided in this application adopts the following technical solution:

[0006] An FPC protective film pressing fixture includes a pressing device body, an upper pressing plate, a lower pressing plate, and a driving mechanism. The pressing device body has a pressing space for FPC pressing material. The lower pressing plate is installed on the bottom surface of the pressing space and provides placement for the FPC pressing material. The driving mechanism is installed inside the pressing device body, with its driving end located within the pressing space. The upper pressing plate is detachably connected to the driving end and moves vertically via the driving mechanism until it contacts the lower pressing plate and presses the FPC pressing material. A detachable guide post is provided within the pressing space, and the guide post abuts against the upper and lower pressing plates to provide limiting and guiding.

[0007] By adopting the above technical solution, the guide column provides guidance for the upper pressure plate and limits the lower pressure plate, so that the upper pressure plate maintains its position and avoids deviation when it moves along the guide column under the driving action of the driving mechanism. At the same time, it limits the position of the lower pressure plate and prevents it from shifting under force during the pressing process, thus stabilizing the pressing position. The detachable design allows the guide column to be removed from the pressing space, losing its limiting function. The lower pressure plate can then be removed from the pressing space for replacement or repair, and the upper pressure plate can also be removed from the driving end for replacement or repair, thereby facilitating material handling and improving installation efficiency.

[0008] Optionally, the guide post has a T-shaped column structure with mounting holes at both ends. The pressing space has an embedding groove on both vertical walls, and a threaded hole is provided in the embedding groove. The guide post is embedded in the embedding groove, and a threaded part is provided in the mounting hole. The threaded part passes through the mounting hole and is screwed into the threaded hole.

[0009] By adopting the above technical solution, when it is necessary to install the guide post, both ends of the guide post are inserted into the embedding groove respectively. The T-shaped column structure allows the guide post to be completely inserted into the embedding groove, so that the mounting hole and the threaded hole are connected. Then, the threaded part passes through the mounting hole and the threaded hole and is tightened to complete the installation of the guide post.

[0010] Optionally, both the upper and lower pressing plates have guide openings corresponding to the installation positions of the guide posts, and the guide openings face outwards, so that the guide posts are inserted into the guide openings.

[0011] By adopting the above technical solution, when it is necessary to disassemble and replace the upper and lower pressing plates, the guide post is separated from the embedded groove, and the guide post is simultaneously separated from the opening of the guide port, so that the upper and lower pressing plates are not limited by the guide post and can be separated and disassembled.

[0012] Optionally, both the upper pressing plate and the lower pressing plate are provided with connecting frames on their exteriors, and the guide openings are simultaneously provided on the connecting frames.

[0013] By adopting the above technical solution, when the upper and lower pressing plates are embedded in the connecting frame, the guide port can be used for positioning and limiting, so that the upper and lower pressing plates are accurately embedded in the connecting frame. The connecting frame is used to fix the upper and lower pressing plates in place, thereby protecting the edges and corners of the upper and lower pressing plates and preventing damage during pressing, thus extending the service life of the upper and lower pressing plates.

[0014] Optionally, the connecting frame is sealed on one side and open on the other, and the upper or lower pressing plate is embedded in the connecting frame through the opening.

[0015] By adopting the above technical solution, the upper or lower pressing plate is embedded into the connecting frame through the opening, and the sealed side can abut against the upper or lower pressing plate to prevent the upper or lower pressing plate from detaching and provide a certain abutment and protection effect.

[0016] Optionally, the guide opening is further provided with a fixing part for clamping the upper pressing plate or the lower pressing plate.

[0017] By adopting the above technical solution, the fixing parts respectively lock the two sides of the connecting frame, while the upper or lower pressing plate is located between the fixing parts. At the same time, the number of fixing parts is the same as the number of guide ports, so that multiple fixing parts can be designed to fix the upper or lower pressing plate to the connecting frame from various positions.

[0018] Optionally, the fixing part has an I-shaped structure and a protective opening that fits with the guide opening.

[0019] By adopting the above technical solution, the protective opening of the fixing part is used in conjunction with the guide post for limiting, so that the fixing part replaces the upper or lower pressing plate and contacts the guide post. Therefore, when subjected to friction or other situations, it will not affect the upper or lower pressing plate, thereby providing a certain protective effect and further extending the service life of the upper or lower pressing plate.

[0020] Optionally, both the upper pressing plate and the lower pressing plate are provided with pressing grooves for the fixing part to fit into.

[0021] By adopting the above technical solution, a flattening groove is provided at the guide opening of the upper and lower pressing plates, so that the fixing part is embedded in the flattening groove and will no longer protrude from the upper or lower pressing plates, thereby enabling the upper and lower pressing plates to be pressed stably during pressing.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The guide post provides guidance for the upper pressure plate and limits the lower pressure plate, so that the upper pressure plate maintains its position and avoids deviation as it moves along the guide post under the driving action of the drive mechanism. At the same time, it limits the position of the lower pressure plate and prevents it from shifting under force during the pressing process, thus stabilizing the pressing position. The detachable design allows the guide post to be removed from the pressing space, losing its limiting function. The lower pressure plate can then be removed from the pressing space for replacement or repair, and the upper pressure plate can also be removed from the drive end for replacement or repair, thus facilitating material handling and improving installation efficiency.

[0024] 2. When it is necessary to install the guide post, insert both ends of the guide post into the embedding groove respectively. The T-shaped column structure allows the guide post to be fully inserted into the embedding groove, so that the mounting hole and the threaded hole are aligned. Then, tighten the threaded part through the mounting hole and the threaded hole to complete the installation of the guide post.

[0025] 3. When it is necessary to disassemble and replace the upper and lower pressing plates, separate the guide post from the embedded groove. The guide post will then separate from the opening of the guide port, so that the upper and lower pressing plates can be separated and disassembled without being limited by the guide post.

[0026] 4. When the upper and lower pressing plates are embedded in the connecting frame, the guide opening can be used for positioning and limiting, so that the upper and lower pressing plates are accurately embedded in the connecting frame. The connecting frame is used to fix the upper and lower pressing plates in place, so as to protect the edges and corners of the upper and lower pressing plates and avoid damage during pressing, thus extending the service life of the upper and lower pressing plates.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the representation of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0038] This application discloses an FPC protective film pressing fixture.

[0039] A FPC protective film lamination fixture, reference Figure 1 As shown, it includes a pressing device body 1, an upper pressing plate 2, a lower pressing plate 3, and a driving mechanism 4; the pressing device body 1 has a pressing space for FPC pressing material. The pressing device body 1 adopts a box-type work platform with a pressing space in the middle and supports on both sides. The pressing space has openings on both sides to place the FPC pressing material into the pressing space. The FPC pressing material includes FPC sheets and protective films, etc.

[0040] The upper pressing plate 2 and the lower pressing plate 3 can be equivalent to the upper mold and the lower mold. Both the upper pressing plate 2 and the lower pressing plate 3 are made of Teflon and glass fiber cloth composite material. This composite material has the characteristics of high temperature resistance, low friction and high wear resistance. It can effectively solve the problems of easy wear of traditional high temperature glass fiber cloth and poor thermal conductivity of silicone gasket. In addition, the smooth surface of the Teflon layer can reduce the friction during the pressing process and avoid damage to the FPC board and protective film.

[0041] The lower pressing plate 3 is installed on the bottom surface of the pressing space. The installation method can be abutting or placing. It provides a place for FPC pressing material. The FPC pressing material can be placed on the lower pressing plate 3. When the upper pressing plate 2 moves toward the lower pressing plate 3, the two adhere to each other and apply pressure to press the FPC board and the protective film into one piece.

[0042] The drive mechanism 4 is installed inside the main body 1 of the pressing device, and the drive end is located in the pressing space. The drive mechanism 4 can adopt a drive structure such as a cylinder or a hydraulic cylinder. The upper pressing plate 2 is detachably connected to the drive end, so that the upper pressing plate 2 can be removed from the drive mechanism 4. The detachable connection method can be plug-in or screw-in. Taking plug-in as an example, the upper pressing plate 2 can be provided with a connecting block. A plug-in groove is opened horizontally on the connecting block. The drive end of the drive mechanism 4 is provided with a plug-in block, which can be inserted into the plug-in groove to complete the detachable connection. When disassembling, the plug-in block can be separated along the plug-in groove.

[0043] When driven by the drive mechanism 4, the upper pressing plate 2 can move vertically until it contacts the lower pressing plate 3 and presses the FPC pressing material into shape. The pressing space is provided with a detachable guide post 5, which passes through the upper pressing plate 2 and the lower pressing plate 3 and abuts against them, providing guidance for the upper pressing plate and limiting the lower pressing plate 3. This ensures that the upper pressing plate 2 maintains its position and avoids deviation as it moves along the guide post 5, while limiting the position of the lower pressing plate 3 to prevent it from shifting under force during the pressing process, thus stabilizing the pressing position. The detachable nature of the guide post 5 allows it to be removed from the pressing space, losing its limiting function. The lower pressing plate 3 can then be removed from the pressing space for replacement or repair, and the upper pressing plate 2 can also be removed from the drive end for replacement or repair, thus facilitating material handling and improving installation efficiency.

[0044] Further reference Figure 1 and Figure 2 As shown, the guide post 5 has a T-shaped column structure with mounting holes 51 at both ends. The top and bottom surfaces of the pressing space are provided with embedding grooves 11. The embedding grooves 11 match the structure of the guide post 5, that is, the embedding grooves 11 are T-shaped grooves. Threaded holes are provided in the embedding grooves 11. The two ends of the T-shaped column structure of the guide post 5 can be embedded in the embedding grooves 11 at both ends of the top and bottom surfaces of the pressing space. At the same time, the mounting holes 51 are connected to the threaded holes.

[0045] The mounting hole 51 is provided with a threaded part 52. The threaded part 52 passes through the mounting hole 51 and is screwed into the threaded hole. The threaded part 52 can be a bolt or a screw. The guide post 5 is fixed in the embedded groove 11 by the threaded part 52, and the installation of the guide post 5 is completed. When disassembling, the threaded part can be taken out from the threaded hole.

[0046] The threaded hole in the illustration is obscured and therefore not shown.

[0047] Specifically, when the guide post 5 needs to be installed, both ends of the guide post 5 are inserted into the embedding groove 11 respectively. The T-shaped column structure allows the guide post 5 to be completely inserted into the embedding groove 11, so that the mounting hole 51 is connected with the threaded hole. Then, the threaded part 52 passes through the mounting hole 51 and the threaded hole and is screwed in to complete the installation of the guide post 5.

[0048] In some embodiments, reference Figure 2 As shown, both the upper pressing plate 2 and the lower pressing plate 3 have guide openings 6 corresponding to the installation positions of the guide posts 5, and the guide openings 6 open outwards, so that the guide posts 5 and the guide openings 6 are inserted into each other. The figure shows the upper pressing plate 2 as an example.

[0049] The guide port 6 allows both the upper pressing plate 2 and the lower pressing plate 3 to detach from the guide post 5 along its opening, but multiple guide posts 5 can also be used to fix the upper pressing plate 2 and the lower pressing plate 3. When it is necessary to disassemble and replace the upper pressing plate 2 and the lower pressing plate 3, the guide post 5 is separated from the embedded groove 11, and the guide post 5 is simultaneously separated from the opening of the guide port 6, so that the upper pressing plate 2 and the lower pressing plate 3 are not limited by the guide post 5 and can be separated and disassembled.

[0050] In some embodiments, reference Figure 3 As shown in the diagram, taking the lower pressing plate 3 as an example, both the upper pressing plate 2 and the lower pressing plate 3 are provided with connecting frames 7 on their exteriors. Guide openings 6 are simultaneously provided on the connecting frames 7, so that the guide openings 6 of the upper pressing plate 2 and the lower pressing plate 3 are aligned with the guide openings 6 of the connecting frames 7. When the upper pressing plate 2 and the lower pressing plate 3 are embedded in the connecting frames 7, the guide openings 6 can be used for positioning and limiting, so that the upper pressing plate 2 and the lower pressing plate 3 are accurately embedded in the connecting frames 7. The connecting frames 7 are used to fix the upper pressing plate 2 and the lower pressing plate 3, so as to protect the edges and corners of the upper pressing plate 2 and the lower pressing plate 3, avoid damage under pressure during pressing, and extend the service life of the upper pressing plate 2 and the lower pressing plate 3.

[0051] Furthermore, the connecting frame 7 is sealed on one side and open on the other. The upper pressing plate 2 or the lower pressing plate 3 is embedded into the connecting frame 7 through the opening. The sealed side can abut against the upper pressing plate 2 or the lower pressing plate 3 to prevent the upper pressing plate 2 or the lower pressing plate 3 from detaching and to provide a certain abutment and protection effect.

[0052] When the connecting frame 7 is set, the connecting frame 7 corresponding to the upper pressing plate 2 can be directly fixedly connected to the driving end of the driving mechanism 4. When the upper pressing plate 2 needs to be replaced, the upper pressing plate 2 can be taken out from the connecting frame 7, making disassembly and assembly more convenient.

[0053] In some embodiments, reference Figure 3 and Figure 4 As shown, the guide opening 6 is also provided with a fixing part 8 for clamping the upper pressing plate 2 or the lower pressing plate 3 in the connecting frame 7.

[0054] The fixing parts 8 respectively hold the two sides of the connecting frame 7, while the upper pressing plate 2 or the lower pressing plate 3 is located between the fixing parts 8. At the same time, the number of fixing parts 8 is the same as the number of guide ports 6, so that multiple fixing parts 8 can be designed to fix the upper pressing plate 2 or the lower pressing plate to the connecting frame 7 from various positions.

[0055] Further reference Figure 3 As shown, the fixing part 8 can be an I-shaped fixing block, and has a protective opening 81 that fits into the guide opening 6. The fixing part 8 is embedded in the guide opening 6, and the protective opening 81 replaces the guide opening 6 to contact the guide post 5, so that the guide post 5 can limit the fixing part 8. After the fixing part 8 connects the connecting frame 7 to the upper pressing plate 2 or the lower pressing plate 3, the fixing part 8 cooperates with the guide post 5 to limit the position, so that the fixing part 8 replaces the upper pressing plate 2 or the lower pressing plate 3 to contact the guide post 5. Therefore, when subjected to friction or other conditions, it will not affect the upper pressing plate 2 or the lower pressing plate 3, thereby providing a certain protective effect and further extending the service life of the upper pressing plate 2 or the lower pressing plate 3.

[0056] Further, refer to Figure 3 and Figure 4 Both the upper pressing plate 2 and the lower pressing plate 3 shown are provided with pressing grooves 31 for the fixing part 8 to fit into. When the fixing part 8 clamps and connects the upper pressing plate 2 or the lower pressing plate 3 to the connecting frame 7, the upper pressing plate 2 or the lower pressing plate 3 will be located inside the fixing part 8. This will cause incomplete pressing when the upper pressing plate 2 and the lower pressing plate 3 press the FPC pressing material. Therefore, pressing grooves 31 are provided at the guide openings 6 of the upper pressing plate 2 and the lower pressing plate 3 so that the fixing part 8 is embedded in the pressing grooves 31 and will no longer protrude from the upper pressing plate 2 or the lower pressing plate 3. This allows the upper pressing plate 2 and the lower pressing plate 3 to be pressed stably during pressing.

[0057] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
