Abstract
A cooperative bonding method for a bonding head of a wire bonding machine, including setting an initial height value of the vertical lifting mechanism to be a difference value; upon receiving a bonding instruction, controlling the bonding head to perform an positioning operation on the target processing chip, controlling the vertical lifting mechanism to descend a preset distance; during the positioning operation of the bonding head on the target processing chip, when the acceleration motion and the overshoot is completed, controlling the vertical lifting mechanism to rise back; and during the rise back process, the pad of the chip does not exceed a residual vibration curve of the bonding head. This achieves the technical effect of improving the bonding efficiency of the bonding head within a small searching area while avoiding impacts on the chip caused by the overshoot during high acceleration positioning of the bonding head.
