[0021] 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. Example

[0022] like Figures 1 to 5 As shown, the temperature and pressure adaptive adjustment component for a flexible circuit board laminating machine in the first aspect embodiment of this utility model includes a body 1 and a door 4 provided on one side of the body 1. The surface of the door 4 is provided with a control panel 6 and an observation window 5. A first cylinder 14 is fixedly connected to the top surface of the inner wall of the body 1. A laminating plate 15 is fixedly connected to the bottom end of the first cylinder 14. A bracket 9 is fixedly connected to the bottom surface of the inner wall of the body 1. A placement plate 10 is fixedly connected to the top surface of the bracket 9. The placement plate 10 and the laminating plate 15 are jointly provided with a control component 2 for adaptively adjusting the temperature during lamination. An auxiliary component 3 is provided inside the body 1 to adjust the extension length of the first cylinder 14 according to the thickness of the flexible circuit board.

[0023] The technical effects achieved by the above embodiments are as follows: by setting a first cylinder 14 and a coating plate 15 in the main body 1, the coating work of the flexible circuit board is completed; at the same time, by controlling the component 2 to detect the temperature of the coating surface and maintain a suitable temperature, and by using the auxiliary component 3 to detect the thickness of flexible circuit boards of different thicknesses, the downward pressure of the coating plate 15 is controlled in conjunction with the first cylinder 14, thereby achieving adaptive adjustment of coating temperature and pressure when facing flexible circuit boards of different thicknesses, and improving the overall use effect of the device. Example

[0024] like Figure 2 and Figure 5 As shown, the temperature and pressure adaptive adjustment component for the flexible circuit board laminating machine includes all the contents of Embodiment 1. In addition, the control component 2 includes a mounting groove 202, which is opened on the top surface of the placement plate 10. A temperature sensor 203 is fixedly connected to the inner wall of the mounting groove 202. The control component 2 also includes a controller 201, whose top surface is fixedly connected to the top surface of the inner wall of the body 1. The controller 201 is electrically connected to the first cylinder 14 and the temperature sensor 203 respectively. The control component 2 also includes a fixing cavity 204 opened inside the laminating plate 15. An electric heating wire 205 is fixedly connected to the inner wall of the fixing cavity 204.

[0025] The technical effect achieved by the above embodiment is as follows: when the first cylinder 14 drives the film-coating plate 15 to move downward to perform the film-coating work, the film-coating temperature of the film-coating surface is detected by the temperature sensor 203. When the detected temperature does not match the set temperature, the signal is sent to the controller 201. Finally, the controller 201 changes the power output of the electric heating wire 205, thereby achieving the effect of adaptive adjustment of the film-coating temperature. Example

[0026] like Figures 2 to 4 As shown, the temperature and pressure adaptive adjustment component for the flexible circuit board covering film machine includes all the contents of Embodiment 2. In addition, the auxiliary component 3 includes a mounting plate 302, one side of which is fixedly connected to one side of the inner wall of the main body 1. A second cylinder 303 is fixedly connected to the bottom surface of the mounting plate 302, and a lower pressure plate 304 is fixedly connected to the bottom end of the second cylinder 303. The auxiliary component 3 also includes a slide rod 306, the wall of which slides against the inner wall of the lower pressure plate 304. The top surface of the slide rod 306 is fixedly connected to a fixing block 310, and a spring 307 is sleeved on the rod wall of the fixing block 310. The bottom end of the slide rod 306 is fixedly connected to a mounting block 308, and a roller 309 is rotatably connected to the inner wall of the mounting block 308. The auxiliary component 3 also includes a laser rangefinder 301 and a receiving plate 305. The top surface of the laser rangefinder 301 is fixedly connected to the top surface of the inner wall of the main body 1, and the bottom surface of the receiving plate 305 is fixedly connected to the top surface of the fixing block 310.

[0027] The technical effect achieved by the above embodiment is as follows: When the flexible circuit board is coated, the second cylinder 303 is activated and fully extended. At this time, the second cylinder 303 drives the lower pressure plate 304 to move downward. Then, as the lower pressure plate 304 moves downward, the slide rod 306 moves upward. The upward movement of the slide rod 306 depends on the thickness of the flexible circuit board. As the slide rod 306 moves upward, the receiving plate 305 also moves upward. At this time, the thickness of the flexible circuit board is known by the cooperation of the laser rangefinder 301 and the receiving plate 305, thereby sending a signal to the first cylinder 14 to control the first cylinder 14 to extend the corresponding length, so as to avoid the first cylinder 14 controlling the coating plate 15 to exert too much or too little downward pressure. Example

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the temperature and pressure adaptive adjustment component for the flexible circuit board covering film machine includes all the contents of Embodiment 3. In addition, the main body 1 has inlet and outlet 7 on both sides of its surface. Each inlet and outlet 7 has two coating rollers 8 on its inner wall. A support plate 11 is fixedly connected to one side of the inner wall of the main body 1. A third cylinder 12 is fixedly connected to the bottom surface of the support plate 11. A cutter 13 is fixedly connected to the bottom surface of the third cylinder 12.

[0029] The technical effects achieved by the above embodiments are as follows: by setting two elastic rubber-coated rollers 8, flexible circuit boards of various thicknesses can be transported, and by using the third cylinder 12 and the cutter 13, the flexible circuit boards after coating can be easily cut.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
