  • Publication number: 20240162472
    Abstract: A bobbin installation unit includes a bobbin, a film supply unit configured to supply an electrode-connecting film to the bobbin, a transfer unit configured to transfer the electrode-connecting film installed in the film supply unit to the bobbin installation unit, an adhesive tape attaching unit installed above the bobbin installation unit and configured to attach an end portion of the electrode-connecting film drawn out to the transfer unit to the bobbin. It also includes a double-sided tape attaching unit configured to attach a double-sided tape to the electrode-connecting film wound on the bobbin, and a frame body on which the adhesive tape attaching unit and the double-sided tape attaching unit are movably installed.

  • Patent number: 8690516
    Abstract: Provided is a method of adjusting a velocity of a transfer arm in a transfer member. The method includes, accelerating the transfer arm from a start point to a first point where a movement velocity reaches a preset reference velocity, dividing a division from the first point to a second point into movement divisions to move the transfer arm in any one of a deceleration motion, an acceleration motion, and a uniform motion according to the respective movement divisions, and decelerating the transfer arm from the second point to a target point. The motion of the transfer arm in the current movement division is different from that in the movement division just before the current movement division. Thus, a different impulse from that in the precedent movement division is applied to a substrate loaded on the transfer arm. Accordingly, the impulse response superposition cancels residual vibration of the substrate, so as to improve transfer efficiency of the transfer member.
