  • Wire clamping system for fully automatic wire bonding machine
    Patent number: 11420287
    Abstract: A wire clamping system for fully automatic wire bonding machine comprises a base, a wire clamping support, a wire clamping assembly, a driving mechanism and an elastic assembly. The wire clamping assembly can move relative to the capillary, so that when the wire clamping system completes the second bond, the metal wire at the end of the capillary may directly extend out of the capillary by the independent movement of the wire clamping assembly and a length thereof can be effectively controlled, in order to form a metal ball in the next first bond. Furthermore, when the wire clamping system completes the second bond, the wire clamping assembly is in a clamping state, which avoids wires flying, even though the second bond is not firmly connected or the machine vibrates.
