Tape attaching device and tape attaching method
View Patent ↗In the tape attaching method of cutting a tape member into conductive tape pieces and attaching the conductive tape pieces onto a plurality of attachment regions which are formed at a side edge part of a board, an attaching step in which the conductive tape pieces is attached onto the attachment region of a first press position, and a moving step, in which by driving a tape sending mechanism to perform the operation of sending the tape member while a press bonding head and a peeling unit are integrally moved relative to the board, the press bonding head is aligned with the attachment region of a second press position, and a separator is peeled from the tape member attached onto the first press position by the peeling unit during the relative movement, are repeated.
1. A tape attaching method which cuts an anisotropic conductive tape into conductive tape pieces of a predetermined attachment length, and attaches the conductive tape pieces onto a plurality of attachment regions which are formed at a side edge part of a board, and which is performed by a tape attaching device comprising a board holding table which holds the board, a tape guiding unit which guides a tape member, which is formed by laminating the anisotropic conductive tape on a separator, from a tape supplying unit to the attachment regions configured by a plurality of electrode units provided at the side edge part of the board along the longitudinal direction thereof, and sends the tape member, which becomes only the separator by attaching the anisotropic conductive tape onto the attachment regions, to the side of a tape collecting unit, a cutting unit which forms breaks at an interval corresponding to the attachment length in the attachment regions on the anisotropic conductive tape, an attaching unit which attaches the anisotropic conductive tape onto the attachment regions by pressing the tape member on the board, which is held on the board holding table and the side edge part of which is received from below by a lower receiving unit, with a press bonding head, a peeling unit which peels the separator from the anisotropic conductive tape attached by the attaching unit, a relative moving unit which horizontally moves the attaching unit and the peeling unit relative to the board holding table in a state that a relative position of the attaching unit and the peeling unit is kept, and a control unit which controls the relative moving unit, the tape guiding unit, the cutting unit, the attaching unit, and the peeling unit, the tape attaching method comprising:
an attaching step in which the conductive tape piece is attached onto one attachment region; and
a moving step in which after the press bonding head is moved up, while the attaching unit and the peeling unit are integrally moved relative to the board holding table by driving the relative moving unit, the tape guiding unit is driven to perform the operation of sending the tape member, so that the press bonding head is aligned with the next attachment region, and while the relative movement is performed until a position where the separator is completely peeled from the anisotropic conductive tape attached onto the attachment region by the peeling unit during the relative movements, the press bonding head and the next conductive tape piece are aligned with the next attachment region,
wherein the attaching step and the moving step are repeated, and
wherein the separator is peeled from the anisotropic conductive tape during the relative movement.
