Description

Technical Field

[0001] This utility model relates to the field of winding equipment, and in particular to a turret-type 3-station shaft winding device for polyimide CPI film. Background Technology

[0002] Polyimide CPI film, due to its excellent heat resistance, electrical insulation, and mechanical properties, has wide applications in high-tech fields such as flexible displays, microelectronics, and aerospace. Its production process typically requires efficient and continuous winding of large rolls of film material. Turret-type roll-up winding equipment, as a key piece of equipment suitable for continuous film winding, achieves rapid switching between workstations through a turret mechanism, thereby ensuring production continuity and automation. It is particularly suitable for handling materials with high requirements for winding quality, such as high-end polyimide CPI film.

[0003] Existing turret-type roll-up and winding equipment typically employs a dual-station design, utilizing a turret mechanism to automatically switch between stations for roll replacement. However, the dual-station design still has certain limitations during roll changeover, especially in scenarios requiring efficient and continuous production. Since each roll change requires stopping one station, the roll changeover time is long, easily causing tension fluctuations and material wrinkling, affecting product quality and production efficiency. Therefore, a turret-type three-station roll-up and winding equipment for polyimide (CPI) film is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a turret-type 3-station roll-up device for polyimide CPI film, aiming to improve the problems in the existing technology where the roll change time is long, which easily causes tension fluctuations and material wrinkles, affecting product quality and production efficiency.

[0011] Three drive units, including A-axis drive, B-axis drive and C-axis drive, are set on the side wall of the first rotating plate and are used to drive each axis independently.

[0012] A rotating gear plate, located on the side wall of the second rotating plate, is used to realize the rotating motion between the first and second rotating plates, thereby enabling workstation switching.

[0013] The drive motor is used to drive the rotating gear plate to achieve multi-station switching.

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a turret-type 3-station roll-up device for polyimide CPI film, comprising: a base 1, used to support the entire equipment structure, ensuring stable operation of each mechanism during high-speed operation and improving the overall reliability and safety of the system; a control electrical box 2, installed on one side of the base 1, used to install the control system and electrical components, with a built-in electrical control system and PLC module, possessing precise logic control and fault detection capabilities, realizing centralized management and control of all functional modules of the whole machine; the control electrical box 2 is equipped with a touch screen 3 for human-machine interaction, supporting real-time parameter setting, status monitoring and fault alarm, improving the convenience of operation and the level of intelligence. Two rotating plates, including a first rotating plate 4 and a second rotating plate 5, are arranged opposite each other and can rotate around a central axis. Both are located inside the base 1, effectively improving the equipment's shaft changing efficiency, achieving seamless switching between winding and unloading shafts, and reducing downtime. Three rotating shafts, including shaft A 11, shaft B 12, and shaft C 13, are installed between the first rotating plate 4 and the second rotating plate 5 at equal intervals via pneumatic chucks 14 (A-axis), 15 (B-axis), and 16 (C-axis), respectively. This ensures balanced center of gravity and symmetrical structure during rotation switching, which is beneficial for dynamic stability during high-speed operation. Each rotating shaft can independently carry the winding task, enabling continuous operation. The side wall of the first rotating plate 4 is equipped with an air-path magnetic ring 6 for lifting. The pneumatic control system for the rotating shaft chucks provides rapid locking and releasing functions for each pneumatic chuck, improving shaft replacement efficiency and ensuring the reliability and sealing of chuck connections. Shafts A 11, B 12, and C 13 are installed at 120° equiangular intervals between the first rotating plate 4 and the second rotating plate 5. Three drive units, including A-axis drive 7, B-axis drive 8, and C-axis drive 9, are located on the side wall of the first rotating plate 4 for independent driving of each shaft, enabling dynamic adjustment of parameters such as winding speed and tension. This adapts to polyimide films of different specifications and thicknesses, improving winding quality and consistency. Polyimide is a high-temperature resistant structural material widely used in aerospace and rocket components, and also has applications in microelectronics. It has unique application value and can be used as a photoresist with a resolution down to the submicron level; it can also be used as an electronic packaging material, coating the chip surface with polyimide as a buffer layer, which can effectively prevent damage caused by thermal stress; the flipping gear 10 is set on the side wall of the second rotating plate 5 to realize the flipping movement of the first rotating plate 4 and the second rotating plate 5, realizing the switching of work positions. The flipping gear 10 is meshed with the output end of the drive motor 18 to realize high-precision, fast and stable turret flipping action, which greatly shortens the work position switching time; the drive motor 18 is used to drive the flipping gear 10 to rotate, thereby realizing multi-work position switching. The side frame 17 is fixedly connected to the side wall of the base 1, and the drive motor 18 is set on the side wall of the side frame 17.

[0033] Working principle: A-shaft 11, B-shaft 12, and C-shaft 13 are installed at 120° equidistant angles between two rotating plates, corresponding to the working position, standby position, and unloading position, respectively. During the winding process, the shaft currently in the working position starts winding the CPI film under the drive of the corresponding drive unit. The roll core is clamped and fixed by the corresponding pneumatic chuck to ensure stable operation. After winding is completed, the operation control electrical box 2 controls the drive motor 18 to drive the rotating toothed disk 10 to rotate, thereby driving the two rotating plates to rotate 120° around the central axis, realizing the rapid switching of the three positions. The original working position enters the unloading position, and the standby position switches to the new working position. Winding can continue without stopping the machine, thus realizing continuous operation of roll changing without stopping the machine.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
