Abstract
The invention provides a transmission mechanism which comprises a feeder, a material belt withdrawing mechanism and a material belt which is connected between the feeder and the material belt withdrawing mechanism. The transmission mechanism also comprises a tension maintaining mechanism which is connected with the material belt. The tension maintaining mechanism is arranged between the feeder and the material belt withdrawing mechanism. The tension maintaining mechanism comprises a base, a core shaft arranged on the base, and an elastic member which is sleeved on the core shaft. When the material belt is relaxed, the elastic member releases an elastic force to drive the core shaft to move to maintain the tension of the material belt. The invention also provides a placement device with the transmission mechanism. According to the transmission mechanism, through adding the tension maintaining mechanism, a stable material belt tension is maintained, thus the material belt is in smooth operation, blocking or breaking of the material belt is effectively prevented, thus the accuracy of the placement device with the transmission mechanism is effectively raised, and a product yield of carrying out placement on the placement device is raised.
