  • Publication number: 20120255837
    Abstract: A transmission mechanism includes a feeder, a belt furling module, a tension maintaining module, and a carrier belt. The tension maintaining module and the belt furling module are positioned on the feeder, and the carrier belt runs along the feeder, the tension maintaining module, and the belt furling module in that order. The tension maintaining module includes a base, a pivot shaft slidably positioned on the base, and an elastic member sleeved on the pivot shaft. When the carrier belt relaxes, the elastic member releases its compression force to drive the pivot shaft to move away relative to the base, thereby maintaining the tension force of the carrier belt. The disclosure also provides a surface mount device using the transmission mechanism, which reduces the likelihood of the carrier belt breaking or jamming, thereby promoting improved precision and yield rate of the surface mounted equipment.
