When the flexible circuit board is to be pressed, the upper film 251 and the lower film 252 are first driven to open to each other by the opening and closing mechanism, and then the flexible circuit board is placed on the placement area of ​​the lower film 252, and then the opening and closing mechanism drives the upper film 251 and the lower film 252 to close to each other, so that the flexible circuit board is tightly wrapped by the release film, and the upper and lower double-layer film structures 250 are located in the pressing window 100, and the pressing machine 10 presses the upper and lower double-layer film structures 250, thereby realizing the pressing of the flexible circuit board. After lamination, the opening and closing mechanism drives the upper film 251 and the lower film 252 to open each other, and the laminated flexible circuit board is moved away. Then, through the operation of the film material conveying mechanism 210 and the film material storage structure, the used release film moves toward the film material storage mechanism 280 and is stored by the film material storage mechanism 280. The film material output mechanism outputs new and unused film material to the film supporting structure to form a new upper and lower double-layer film structure 250. Then, the next flexible circuit board to be laminated is placed in the placement area and the lamination work is completed. Then, the laminated flexible circuit board is moved away. Such a cyclic operation can realize continuous lamination of multiple flexible circuit boards. The release film output and storage structure for lamination of flexible circuit boards provided by the present invention effectively realizes the conveying of release film and the storage of used release film, and automatically realizes the wrapping and separation of flexible circuit boards, which greatly improves the lamination efficiency of flexible circuit boards.

[0027] Specifically, the film material storage mechanism 280 includes a first motor, a storage cylinder 282 fixedly connected to the rotating shaft of the first motor, and a first conveying power structure 283 for driving the release film to be transported in the direction of the storage cylinder 282; the first motor drives the storage cylinder 282 to rotate so that the release film conveyed by the first conveying power structure 283 is wound and stored on the outer periphery of the storage cylinder 282; in this way, the first conveying power structure 283 drives the release film to be transported in the direction toward the storage cylinder 282, and at the same time, the rotating shaft of the first motor rotates, and the rotating shaft of the first motor drives the storage barrel to rotate, thereby realizing the storage of the release film conveyed by the first conveying power structure 283; by controlling the rotation of the first motor and the operation of the first conveying power structure 283, it can be controlled whether the used film material is stored.

[0028] Specifically, the first conveying power structure 283 includes two first rotating rods 2831 which are arranged opposite to each other up and down, and the release film is located between the two first rotating rods 2831.

The first track groove and the first track are freely slidably matched, so that the first gravity rod 284 can move freely up and down; in this way, through the arrangement of the first gravity rod 284, it can be ensured that the entire release film is in a taut state and will not be in a relaxed state. When the film material conveying mechanism 210 outputs the film material, the second gravity rod 214 will fall to tighten the release film as a whole. When the film material storage mechanism 280 stores the used film material, the film material is stored and the first gravity rod 284 will slide upward.

[0030] Furthermore, photoelectric sensors are respectively provided at the highest position and the lowest position to which the first gravity rod 284 can move; when the first gravity rod 284 moves to the lowest position, the photoelectric sensor at the lowest position senses the first gravity rod 284, and the first motor of the film material storage mechanism 280 starts working to store the film material; when the first gravity rod 284 moves to the highest position, the photoelectric sensor at the highest position senses the first gravity rod 284, and the first motor of the film material storage mechanism 280 stops working and stops storing the film material.

[0033] The release film is transported forward in a direction away from the reel 212, and a second gravity rod 214 that can move freely up and down is arranged in front of the second conveying power structure 213. The second gravity rod 214 is arranged horizontally, and the second gravity rod 214 is located above the release film; the shell 30 is provided with a longitudinally arranged second track, and the second gravity rod 214 is fixedly connected to the second connecting structure, and the second connecting structure is provided with a longitudinally extending second track groove, and the second track groove is freely slidably matched with the second track, so that the second gravity rod 214 can move freely up and down; in this way, through the arrangement of the second gravity rod 214, it can be ensured that the entire release film is in a taut state and will not be in a relaxed state. When the film material conveying mechanism 210 outputs the film material, the second gravity rod 214 will fall, so that the release film is tightened as a whole. When the film material storage mechanism 280 stores the used film material, the film material is stored, and the film material will move as a whole, driving the second gravity rod 214 to slide upward.

[0034] Furthermore, photoelectric sensors are respectively provided at the highest position and the lowest position to which the second gravity rod 214 can move; when the second gravity rod 214 moves to the lowest position, the photoelectric sensor at the lowest position senses the second gravity rod 214, and the second motor of the film material conveying mechanism 210 stops working; when the film material storage mechanism 280 stores the film material, the second gravity rod 214 will be driven to move to the highest position, and the photoelectric sensor at the highest position senses the second gravity rod 214, then the second motor of the film material conveying mechanism 210 starts working, and the reel 212 rotates and outputs the film material.

[0035] The membrane-supporting structure includes a lower membrane-supporting assembly and an upper membrane-supporting assembly which are arranged opposite each other up and down; the lower membrane-supporting assembly includes a first rear membrane-supporting rod 2211 which can move horizontally and up and down, and a first front membrane-supporting rod 2212 which can move up and down, the first rear membrane-supporting rod 2211 abuts against the upper end surface of the lower membrane 252, and the first front membrane-supporting rod 2212 abuts against the lower end surface of the lower membrane 252; the upper membrane-supporting assembly includes a second rear membrane-supporting rod 2221 and a second front membrane-supporting rod 2222, the second rear membrane-supporting rod 2221 abuts against the lower end surface of the upper membrane 251, and the second front membrane-supporting rod 2222 abuts against the upper end surface of the upper membrane 251; in this way, the cooperation of the lower membrane-supporting assembly and the upper membrane-supporting assembly which are arranged opposite each other up and down realizes the expansion of the release film to form an upper and lower double-layer membrane structure 250.

[0036] The opening and closing mechanism includes a brake mechanism for pressing and fixing the first front film-supporting rod 2212 and the release film, and a driving mechanism for driving the first front film-supporting rod 2212 and the first rear film-supporting rod 2211 to move up and down.

The movement direction of the push rod 2311 is perpendicular to the extension direction of the push rod 2311.

The pressing pieces 2312 have a contact end surface for contacting the release film, and the contact end surface is provided with glue. In this way, when it is necessary to press and fix the first front film support rod 2212 to the release film, it is only necessary to push the push rod 2311 horizontally so that the pressing pieces 2312 arranged on the outer periphery of the push rod 2311 press the release film. The adhesive is provided on the contact end surface of the pressing piece 2312 to further improve the pressing and fixing effect.
