  • Publication number: 20240409354
    Abstract: A bonding method for using a bonding apparatus includes: transporting and reeling a carrier tape which is packaged with an adhering component, on a pressing assembly, and bending the carrier tape through a bending member to be divided into an input section and an output section; driving a roller to indirectly press and abut a front end of the adhering component to bring the adhering component into contact with a bonding start point a base component; and rolling the roller over the carrier tape to attach the adhering component to the bonding area while moving the bending member to indirectly scrape the adhering component from the carrier tape so as to firmly attach the adhering component to the base component without generation of air bubbles.

  • Publication number: 20240409355
    Abstract: A bonding device includes a first carrying module for a tape assembly to be disposed thereon and reeling a carrier tape and a cover tape, a driving module disposed to drive an up-down movement and a rotation of the first carrying module, a second carrying module movably disposed on the first carrying module, and a bonding module disposed on the second carrying module. The bonding module includes a bending member on and through which a carrier tape is reeled and bent to be divided into an input section and an output section. The bending member is moved together with a roller, during rolling of the roller, to indirectly scrape an adhering component from the carrier tape so as to facilitate attachment of the adhering component to the base component.

  • Publication number: 20230298913
    Abstract: A bonding apparatus for attaching an adhering pad to a base component includes a feeding and holding frame for feeding and holding the base component in a conveying route, a suspending carrier mounted above the conveying route, and a bonding device disposed on and movable with the suspending carrier. The bonding device has a feeding reel on which the tape assembly is disposed and from which the tape assembly is pulled and fed along a feeding route, and an attaching head which is disposed at said feeding route to divide the pulled section into an input side and an output side. When the attaching head is moved toward the input side, the adhering pad is removed from the carrier tape while attached to the base component.
