Thin film reeling device

Abstract

A thin film reeling device is provided. The device comprises a rotating shaft and a rotating bowl. The rotating shaft is nested into the rotating bowl for reeling a thin film, and two ends of the rotating shaft are provided with a first baffle plate and a second baffle plate for reeling the thin film regularly, respectively.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a thin film reeling device.BACKGROUND OF THE INVENTION[0002]During punching of a Tape Carrier Package (TCP) and a Chip On Flexible Printed Circuit (COF), the punched TCP or COF is reeled up through a rotating shaft controlled by an electrical motor, and the start and end positions of the TCP or COF is controlled by a distance by which the electrical motor rotates during the punching. The rotating shaft in this conventional technology cannot reel the punched TCP and COF always properly, and the phenomenon that the intermediate portion bulges and the two ends shrink to the intermediate portion may occur. In that case, an alignment hole of the TCP or COF cannot be engaged with a gear of a punching mechanism accurately, which leads to the displacement of the TCP or COF when the punching mechanism are in operation and even leads to the phenomenon that the TCP or COF is cut off.SUMMARY OF THE INVENTION[0003]An object of the pres...

Benefits of technology

[0019]The embodiments of the invention provide a thin film reeling device, which can regulate a position of a thin film during reeling of the punched thin film by disposing a rotating bowl around a rotating shaft and providing baffle plates at two ends of the rotating bowl. With such configuration, an alignment hole of the thin film can accurately engage with a gear of a punching mechanism, and the punching mechanism can perform an accurate punching and avoid the case that a TCP or COF is cut in deflection or cut off, thus increasing product efficiency and decrease waste. Preferably, a notch may be formed on either baffle plate so as to observe the reeling height of the punched thin film and is helpful for cleaning the punched thin film from the reeling device in time. An operation hole may be formed on either baffle plate, which is convenient for inserting and pulling and easy for operation.

Problems solved by technology

The rotating shaft in this conventional technology cannot reel the punched TCP and COF always properly, and the phenomenon that the intermediate portion bulges and the two ends shrink to the intermediate portion may occur.

In that case, an alignment hole of the TCP or COF cannot be engaged with a gear of a punching mechanism accurately, which leads to the displacement of the TCP or COF when the punching mechanism are in operation and even leads to the phenomenon that the TCP or COF is cut off.
