Description

Intelligent fixed line speed double-sided winding transmission device

The invention relates to a transmission device, in particular to a smart fixed-speed double-wound winding transmission device used in a roll-type conductive plastic film coating technology.

In recent years, the development of soft electronic technology between paper and non-paper has been quite rapid, and the industrial demand related to "soft electronic technology" has grown exponentially, and it also presents a wide range of application opportunities, including in the field of soft electronics. In the display panel application, the conductive plastic (PET) film with high light transmittance and flexibility will gradually replace the traditionally non-flexible glass conductive film, because the advantages of the conductive plastic film include, for example, the weight of the glass. The conductive film is lightweight, the volume is thinner than the glass conductive film, and has various advantages such as flexibility, so it becomes the mainstream of the future development of soft electronic technology.

In the aforementioned soft electronic technology field, one of the main development technologies is to deposit an indium tin oxide (ITO) transparent conductive film on a conductive plastic film to facilitate subsequent technological development. However, when the indium tin oxide transparent conductive film is sputtered on the conductive plastic film, the high temperature generated by the sputtering film is limited by the material properties of the conductive plastic film (poor heat resistance and high temperature resistance), and the conductive plastic film is made. Improper curling may occur during processing.

Since "rolling type conductive plastic film coating technology" is also one of the key technologies in the field of soft electronic technology, indium tin oxide transparent conductive film coating is produced by continuous sputtering on the conductive plastic film which has been pretreated. A large number of smaller and cheaper, and faster, large-size (about 600 mm wide) indium tin oxide transparent conductive film products are available. However, in the sputtering process of the indium tin oxide transparent conductive film of the large-sized conductive plastic film, the coating quality of the indium tin oxide transparent conductive film and the yield are obviously related to many factors, such as the mechanical properties of the conductive plastic film, Factors such as transmission tension, machine component tolerances, operating speed and vibration are all related. Even during the feeding process, the tension between the reel and the reel will affect the transfer process of the conductive plastic film, which may cause lateral shift, and even lead to an annual ring phenomenon in which the winding quality of the conductive plastic film is not good. Therefore, it can be known that the conventional large-size roll-type indium tin oxide transparent conductive film coating process is prone to film defects, bumps, scratches, and slippery defects.

Therefore, in order to improve the efficiency of the roll-type conductive plastic film coating technology, it is extremely necessary to develop a new type of roll-type technology, thereby improving the overall operational efficiency of the conductive plastic film coating technology, and reducing the development time and related manufacturing costs.

The intelligent fixed-speed double-wound winding transmission device of the invention can stably control the feeding speed of the conductive plastic film, and can simultaneously achieve the double-sided coating effect.

The intelligent fixed-speed double-wound winding transmission device of the present invention uses a feed reel, a first coated reel, a second coated reel, a discharge reel, a first dancing wheel, and a second dancing The wheel, the 3rd dancing wheel and the 4th dancing wheel are combined, and the servo system is also included to set and control the relevant parameters.

Through the control of the conductive plastic film of the present invention for feeding, the phenomenon that the conductive plastic film may be bumped, slipped, offset, and scratched during the curling process can be avoided.

The invention can simultaneously improve the reproducibility, the success rate and the reliability of the transformation parameters during the winding process.

The invention can maintain the overall tension of the conductive plastic film and perform coating at a fixed speed, effectively achieving the effect of providing transmission speed and good stability, and enabling the coating process to be stably performed.

Continuing with the servo system 200 shown in FIG. 1, during the feeding process, since the servo system 200 is employed, the tension of the conductive plastic film 300 between the reels produces a fairly uniform symmetry, and no lateral direction is generated. The offset is not affected by the transfer process of the conductive plastic film 300, and the occurrence of the annual ring phenomenon is also eliminated. Through the control of the conductive plastic film 300 of the present invention, the phenomenon that the conductive plastic film 300 may be bumped, slipped, offset, and scratched during the curling process can be avoided, and the conductive plastic film 300 can be stably controlled. The feed speed is in the range of 0.5 m to 10 m/min ± 0.1% (0.5-10 m/min ± 0.1%) while improving the reproducibility, success rate, and transformation during the winding process of the present invention.
