Description

Technical Field

[0001] This utility model relates to the technical field of lamination devices for flexible circuit board production, and in particular to a lamination device for flexible circuit board production. Background Technology

[0002] Flexible printed circuit boards (FPCBs) are crucial connection components in electronic devices, and their production requires a lamination process to ensure tight adhesion between the layers. Existing lamination equipment commonly suffers from unstable workpiece fixation, especially in the processing of thin or irregularly shaped FPCBs. Due to the lack of effective positioning structures, workpieces are prone to shifting or warping during lamination, leading to insufficient lamination accuracy and reduced product yield. Traditional methods often rely on manual adjustment or complex fixtures for fixation, which is not only inefficient but also difficult to adapt to the needs of workpieces of different sizes and shapes. Furthermore, existing equipment is cumbersome to operate when fixing and releasing workpieces, has a low degree of automation, and cannot meet the requirements of efficient continuous production.

[0003] To address these issues, we propose a lamination device for flexible circuit board production. Utility Model Content

By setting up a linkage structure of opening and closing plate one, opening and closing plate two, and limiting plate, the device achieves rapid and accurate fixing of the workpiece. When opening and closing plate two is open, it facilitates the embedding of the workpiece into the placement table. When closed, it cooperates with the synchronous extension of telescopic plate and limiting plate to clamp the workpiece from both sides, effectively preventing displacement or deformation during the pressing process and significantly improving the pressing accuracy. At the same time, the combination design of the lower pressure plate and inner plate can be flexibly adjusted according to the size of the workpiece to ensure uniform distribution of pressing force, further guaranteeing product quality and solving the problems mentioned in the background art.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5A pressing device for producing flexible circuit boards includes a processing table 1 with a mounting frame 2 fixed to its side wall. The mounting frame 2 has a lower pressure plate 3 at its bottom. A conveyor belt 8 is installed inside the processing table 1. The inlet end of the conveyor belt 8 is connected to a placement table 7. A first opening and closing plate 9 and a second opening and closing plate 10 are respectively hinged to both sides of the placement table 7. The second opening and closing plate 10 has a telescopic plate 12 embedded in it. A limiting plate 11 is also movably provided on the side wall of the placement table 7.

[0026] During processing, the operator places the flexible circuit board on the placement table 7. At this time, the first opening plate 9 closes to isolate the conveyor belt 8, and the second opening plate 10 opens via an electric rotating shaft to form an opening for embedding the workpiece. After the workpiece is in place, the second opening plate 10 closes, and its internal telescopic plate 12 extends outward to one side of the workpiece. At the same time, the limiting plate 11 is driven by an electric push rod to move to the other side, clamping the workpiece together with the telescopic plate 12. Since the length of the telescopic plate 12 is only half that of the second opening plate 10, it will not interfere with the limiting plate 11 when extending, ensuring stable clamping.

[0027] After fixing, the mounting frame 2 is lowered to a suitable height via the electric telescopic rod 4, facilitating the replacement of the inner plate 6 according to the size of the workpiece. The lower pressure plate 3 is lowered vertically via the electric lifting rod 5 until it contacts the top of the limiting plate 11 and the telescopic plate 12. Subsequently, the inner plate 6 is pressed down via the bolted telescopic rod, pressing it tightly against the inner wall of the opening and closing plate 9 and the side wall of the placement platform 7, applying uniform pressure to the workpiece to complete the pressing. After pressing, the opening and closing plate 9 opens, and the limiting plate 11 continues to extend, pushing the workpiece to the conveyor belt 8, where it is output and collected through the discharge port 13.

[0028] The working principle of this utility model is as follows: As shown in the figure, it includes a processing table 1, a fixed mounting frame 2 on its side wall, a pressure plate 3 at the bottom of the mounting frame 2, a conveyor belt 8 installed inside the processing table 1, the inlet end of the conveyor belt 8 connected to the placement table 7, and a hinged opening and closing plate 9 and a hinged opening and closing plate 10 on both sides of the placement table 7, wherein the hinged opening and closing plate 10 has a telescopic plate 12 embedded in it, and a limiting plate 11 is also movably provided on the side wall of the placement table 7.

[0029] During processing, the operator places the flexible circuit board on the placement table 7. At this time, the first opening plate 9 closes to isolate the conveyor belt 8, and the second opening plate 10 opens via an electric rotating shaft to form an opening for embedding the workpiece. After the workpiece is in place, the second opening plate 10 closes, and its internal telescopic plate 12 extends outward to one side of the workpiece. At the same time, the limiting plate 11 is driven by an electric push rod to move to the other side, clamping the workpiece together with the telescopic plate 12. Since the length of the telescopic plate 12 is only half that of the second opening plate 10, it will not interfere with the limiting plate 11 when extending, ensuring stable clamping.

[0030] After fixing, the mounting frame 2 is lowered to a suitable height via the electric telescopic rod 4, facilitating the replacement of the inner plate 6 according to the size of the workpiece. The lower pressure plate 3 is lowered vertically via the electric lifting rod 5 until it contacts the top of the limiting plate 11 and the telescopic plate 12. Subsequently, the inner plate 6 is pressed down via the bolted telescopic rod, pressing it tightly against the inner wall of the opening and closing plate 9 and the side wall of the placement platform 7, applying uniform pressure to the workpiece to complete the pressing. After pressing, the opening and closing plate 9 opens, and the limiting plate 11 continues to extend, pushing the workpiece to the conveyor belt 8, where it is output and collected through the discharge port 13.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
