The high-temperature lamination device generally consists of a base, a support, an electric telescopic rod, a high-temperature lamination plate, and a winding drum. In use, the flexible circuit board to be processed is placed on the base, and then the winding drum drives the film to rotate so that it is fitted onto the flexible circuit board. Subsequently, with the assistance of the support, the electric telescopic rod is activated to drive the high-temperature lamination plate to press the film and the flexible circuit board together.

[0003] A search revealed a Chinese patent application (CN202121643967.3) proposing a high-temperature pressing device for a smart heating plate. The bottom wall of the first inner cavity is slidably connected to a third rod via a slide rail. One end of the third rod is fixedly connected to an arc-shaped block. A movable rod is located inside the first inner cavity, and a conical plug is fixedly connected to the top of the movable rod. In this prior art, a placement groove is opened above the worktable, and the material to be processed is placed in the placement groove for positioning, thus facilitating the restriction of the processed material and preventing displacement during subsequent pressing.

[0004] In the aforementioned existing methods, the material to be processed is mainly processed by opening slots in the high-temperature pressing device. However, compared with the traditional high-temperature pressing device for flexible circuit boards, the high-temperature pressing device is prone to damage to the flexible circuit board due to excessive pressure caused by the extrusion of the high-temperature pressing plate, thus affecting the performance of the flexible circuit board.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a high-temperature pressing device for flexible circuit boards, including a base 1, a control panel 11 fixedly connected to the outer side of one end of the base 1, and a first bracket 12 fixedly connected to the upper side of the middle end of the base 1. An electric telescopic rod 13 is fixedly connected to the upper end of the first bracket 12, and a high-temperature pressing plate 14 is fixedly connected to the lower end of the electric telescopic rod 13 through the first bracket 12. A fixing frame 15 is fixedly connected to the outer side of the end of the base 1 near the control panel 11, and a motor 16 is fixedly connected to the outer side of one end of the fixing frame 15. The output shaft of the motor 16 is fixedly connected to a receiving device. The winding drum 17 has one end rotatably connected to the fixed frame 15 away from the motor 16. A film 18 is wrapped around the outside of the winding drum 17, and a protective component 2 is fixedly connected to the middle of the base 1. The protective component 2 includes a placement platform 21 inserted into the inner side of the middle of the base 1, and limit blocks 22 are fixedly connected to both ends of the placement platform 21. The end of the limit block 22 away from the placement platform 21 is inserted into the base 1. The protective component 2 can buffer and protect the flexible circuit board being squeezed during processing, thereby avoiding damage to the flexible circuit board caused by high pressure and improving the stability during processing.

[0027] like Figure 4 As shown, a placement slot 23 is provided inside the upper end of the placement platform 21, and a material retrieval slot 24 is provided at both ends of the placement slot 23. The flexible circuit board placed on the placement platform 21 can be placed through the placement slot 23, and the flexible circuit board can be easily removed by using the material retrieval slot 24.

[0028] like Figure 3 As shown, a rod 25 is fixedly connected to the middle of the lower side of the placement platform 21, and a piston 26 is fixedly connected to the lower end of the rod 25. A sleeve 27 is sleeved on the outside of the piston 26. When the placement platform 21 moves, it drives the rod 25 and the piston 26 to move inside the sleeve 27, and the piston 26 compresses the air inside the lower end of the sleeve 27.

[0029] like Figure 3 As shown, a spring 28 is sleeved on the outside of the piston 26 and the sleeve 27. The upper end of the spring 28 is fixedly connected to the placement platform 21, and the lower end of the spring 28 is fixedly connected to the filter screen plate 29. The outer end of the filter screen plate 29 is fixedly connected to the base 1, and the lower end of the sleeve 27 is fixedly connected to the filter screen plate 29. The spring 28 is compressed by the movement of the placement platform 21 under the support of the filter screen plate 29. The elastic potential energy of the spring 28 provides secondary buffering for the downward movement of the placement platform 21.

[0030] like Figure 2As shown, the lower ends of the filter plate 29 are fixedly connected to the second bracket 210, and the lower inner side of the second bracket 210 is fixedly connected to the filter screen cover 211. The upper inner side of the filter screen cover 211 is fixedly connected to the motor 212, and the output shaft of the motor 212 is fixedly connected to the fan 213. The second bracket 210 and the filter screen cover 211 support and protect the motor 212 and the fan 213. At the same time, after the motor 212 is started, the output shaft drives the fan 213 to rotate, and the rotation of the fan 213 accelerates the flow of air around it.

[0031] like Figure 4 As shown, a cutting table 214 is provided on the outer side of the upper end of the placement platform 21, and the lower end of the cutting table 214 is fixedly connected to the base 1. A cutting blade 215 is fixedly connected to the upper end of the cutting table 214. With the support of the cutting table 214, the film 18 covering the outside of the flexible circuit board is cut by the cutting blade 215 in conjunction with the downward movement of the high temperature pressing plate 14.

[0032] Working principle: When processing flexible circuit boards, the flexible circuit board to be processed is first placed in the placement slot 23. Then, the motor 16 is controlled to operate through the control panel 11. After the motor 16 operates under the support of the fixing frame 15, the output shaft drives the winding drum 17 to rotate. The rotation of the winding drum 17 is used to wind up the film 18. As the film 18 is wound up, it moves. When the uncut part of the film 18 covers the flexible circuit board, the motor 16 is then turned off. Then, the electric telescopic rod 13 and the high-temperature pressing plate 14 are controlled to operate through the control panel 11. The electric telescopic rod 13 operates under the support of the control panel 11. The extended platen 14 moves, and after it rotates, it is heated. As the platen 14 moves downward, it adheres to the film 18 and the flexible circuit board, and is then compressed. The placement platform 21 is compressed and moves downward under the limit of the limiting block 22. After the placement platform 21 moves downward, it is buffered by the insertion rod 25 and the piston 26 with the assistance of the sleeve 27. At the same time, the downward movement of the placement platform 21 compresses the spring 28 under the support of the filter plate 29. At this time, the compression of the air at the lower end of the sleeve 27 by the piston 26 and the elastic potential energy of the spring 28 are used to compress the flexible circuit. The pressure on the board is buffered. When the upper end of the placement platform 21 moves down to the same height as the cutter 215, the film 18 on the outer end of the flexible circuit board is cut as the high-temperature pressing plate 14 continues to press down. After cutting, the film 18 and the flexible circuit board are pressed together by the high temperature of the high-temperature pressing plate 14. After pressing, the control panel 11 is activated again to control the electric telescopic rod 13 to move the high-temperature pressing plate 14 upward. As the high-temperature pressing plate 14 moves upward, the elastic potential energy of the spring 28 pushes the placement platform 21 to move upward and back to its original position with the assistance of the limit block 22. After the placement platform 21 moves upward and resets, it can then... The flexible circuit board placed in the placement slot 23 is taken out through the material picking slot 24. Then, the motor 212 can be controlled to run through the control panel 11. Under the support of the second bracket 210 and the filter screen cover 211, the output shaft of the motor 212 drives the fan 213 to rotate. The rotation of the fan 213 causes the air inside the upper part of the base 1 to flow rapidly. After the air flows rapidly, it forms an airflow. The rapid flow of air causes the air to enter the middle part of the base 1 from the upper part and then be discharged through the lower part of the base 1. The airflow is used to dissipate the heat at the placement platform 21, so as to avoid the residual heat affecting the subsequent pressing.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
