Abstract

This invention discloses an FPL (Flat Plastic Film) tearing mechanism for black and white electronic paper production, comprising an unwinding mechanism, a winding mechanism, a receiving platform, and a roller. The FPL aluminum film roll is unwound in the unwinding mechanism and wound in the winding mechanism. Support arms are provided on both sides of the roller, and the two ends of the roller are rotatably connected to the support arms. The support arms are mounted on one end of the receiving platform. A follower sleeve is fixedly connected to the roller, forming a film passage between the follower sleeve and the receiving platform for the aluminum film to pass through. The follower sleeve is adhesive. Several air holes are provided on the receiving platform, near the roller. An air cavity is provided inside the receiving platform, and the air holes are connected to the air cavity. Hot air is supplied to the air cavity through pipes. This invention effectively peels the FPL from the aluminum film using the adhesive roller. Heating with hot air from the air holes softens the FPL and aluminum film, promoting separation. An eccentric shaft allows the roller to swing to a certain extent, increasing the tearing effect on the FPL.

Description

Technical Field

[0001] This invention belongs to the field of electronic paper production technology, specifically relating to an FPL tearing mechanism for black and white electronic paper production. Background Technology

[0002] Flexible electronic paper (EPD), also known as digital paper, is an ultra-thin and ultra-light display screen, which can be understood as "a display that is as thin, flexible, and erasable as paper." Existing flexible electronic paper (EPD) mainly consists of FPL (electronic paper film), PS film (polystyrene protective film), PI film (polyimide film), IC (integrated circuit chip), and FPC (flexible printed circuit board). The PI film, PI film, FPL, and PS film are bonded together sequentially from bottom to top using EC adhesive. The IC is fixed to the FPL by IC reinforcing adhesive, and the FPC is fixed to the FPL by UV adhesive (ultraviolet curing adhesive). FPLs are generally purchased directly, and each FPL is individually glued to an aluminum film and rolled up. When in use, the FPL needs to be peeled off the aluminum film. Existing FPL peeling mechanisms utilize a receiving platform to change the direction of travel of the aluminum film at a large angle, thus separating the FPL from the aluminum film. When the adhesion between the FPL and the aluminum film is not strong, this device can effectively peel the film, and the mechanism structure is simple. However, when the electronic paper is black and white, the existing film-tearing mechanism often fails to effectively tear off the FPL due to the strong adhesion between the FPL and the aluminum film used in its production, thus affecting normal production. Therefore, it is necessary to improve the aforementioned FPL film-tearing mechanism. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an FPL tearing mechanism for black and white electronic paper production, wherein the FPL is sequentially adhered to aluminum film, and the aluminum film with FPL is rolled up to form an FPL aluminum film roll. The FPL tearing mechanism includes an unwinding mechanism, a winding mechanism, a receiving platform, and a roller. The FPL aluminum film roll is unwound in the unwinding mechanism, and the aluminum film is wound up in the winding mechanism. Support arms are provided on both sides of the roller, and the two ends of the roller are rotatably connected to the support arms. The support arms are installed at one end of the receiving platform.

The follower sleeve is adhesive. Several air holes are provided on the receiving platform, with the air holes located at one end of the receiving platform near the roller. An air cavity is provided inside the receiving platform, and the air holes are connected to the air cavity. The air cavity is supplied with hot air through a pipe.

[0019] like Figure 1-4As shown, an FPL tearing mechanism for black and white electronic paper production includes FPL1 sequentially adhered to aluminum film 2. The aluminum film 2 with FPL1 adhered to it is rolled up to form an FPL1 aluminum film roll 5. The FPL1 tearing mechanism includes an unwinding mechanism 3, a winding mechanism 4, a receiving platform 6, and a roller 7. The FPL1 aluminum film roll 2 is unwound in the unwinding mechanism 3 and wound up in the winding mechanism 4. Support arms 8 are provided on both sides of the roller 7, and the two ends of the roller 7 are rotatably connected to the support arms 8. The support arms 8 are installed at one end of the receiving platform 6. A follower sleeve 9 is fixedly connected to the roller 7. A film passage 15 for the aluminum film to pass through is formed between the follower sleeve 9 and the receiving platform 6. The follower sleeve 9 is adhesive. The receiving platform 6 is provided with a plurality of air holes 16. The air holes 16 are located at one end of the receiving platform near the roller 7. An air cavity is provided inside the receiving platform 6, and the air holes 16 are connected to the air cavity. The air cavity is supplied with hot air through pipes. After being unwound in the unwinding mechanism 3, the aluminum film 2 with FPL1 passes over the receiving platform 6, then through the film passage 15, and is finally wound up by the winding mechanism 4. At the film passage 15, the aluminum film 2 makes a large-angle turn, and FPL1 comes into contact with the adhesive follower sleeve 9 on the roller 7, thus separating from the aluminum film 2. The FPL1 detached from the aluminum film 2 is caught by other equipment and transferred to the next step of the operation. The empty aluminum film 2 is wound up by the winding mechanism 4. The lower surface of the receiving platform 6 near the roller 7 is also provided with an inclined surface, which can increase the turning angle of the aluminum film 2, which is conducive to the separation of FPL1 and aluminum film 2. Hot air with a certain temperature is sprayed out through the air hole 16 to quickly preheat the FPL1 and aluminum film 2 that are about to be torn apart, promoting the separation of FPL1 and aluminum film 2.

[0020] Furthermore, there are multiple follower sleeves 9, and a clearance gap 10 is formed between adjacent follower sleeves 9. Before separation after unwinding, FPL1 is coated with a certain amount of silver paste using other equipment. The clearance gap 10 can avoid the silver paste on FPL1 during separation, preventing the silver paste from being stuck to it.

[0021] Furthermore, double-sided tape is adhered to the follower sleeve 9. The double-sided tape can be replenished as it decreases.

[0022] Furthermore, the support arm 8 is provided with an elongated mounting hole 11, into which a mounting screw 12 is inserted. The receiving platform 6 is provided with a threaded hole 23 for the mounting screw 12 to be screwed in. In this way, the position of the roller shaft 7 relative to the receiving platform 6 is adjustable, and the angle of the support arm 8 is adjustable.

[0023] Furthermore, mounting holes 20 are provided on both sides of the receiving platform 6, and bearings 21 are provided in the mounting holes 20. Rotating blocks 22 are installed inside the bearings 21. Threaded holes 23 are respectively provided on the rotating blocks 22, and mounting screws 12 are threadedly connected to the rotating blocks 22. A turntable 23 driven by a micro motor 24 is installed on one side of the receiving platform 6. An eccentric shaft 25 is provided on the turntable 23, and the eccentric shaft 25 extends into the mounting elongated holes 11. By rotating the eccentric shaft 25, the support arm 8 is driven to swing at a set frequency, so that the follower sleeve 9 swings with the roller shaft 7 after FPL1 is attached, creating a tearing effect on the FPL1 attached to the aluminum film 2, thereby improving the separation efficiency of FPL1 and aluminum film 2.

[0024] Furthermore, the unwinding mechanism 3 includes a rotatably configured unwinding shaft, and several guide shafts 13 are provided between the unwinding shaft and the receiving platform 6. The purchased aluminum film roll with FPL is freely unwound onto the unwinding shaft. To stabilize the tension of the aluminum film, a tension adjustment mechanism can be installed on the unwinding shaft for unwinding.

[0025] Furthermore, the winding mechanism 4 includes a winding shaft driven by a winding motor, and a plurality of guide shafts 13 are provided between the winding shaft and the receiving platform 6. The aluminum film that has been stripped of FPL is wound on the winding shaft, and the winding motor drives the winding shaft to rotate, pulling the aluminum film to wind it up.

[0026] It is worth mentioning that the technical features such as motors involved in this patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this patent. This patent will not be further elaborated in detail.

[0027] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
