8. A conveyor comprising the high precision stepper drive structure of claim 1.
9. A conveying method of a conveyor according to claim 7, comprising the steps of:
step one: the conveyor is arranged between two production lines, the two production lines can continuously process the same workpiece, and the power assembly is started while the two production lines are started;
step two: when the power assembly works, the lifting assembly and the transmission assembly are driven to alternately act, wherein when the lifting assembly acts, the transmission assembly is in a static state, at the moment, the lifting assembly drives the supporting rod (18) to move upwards and then move downwards to finish resetting, when the supporting rod (18) moves upwards, under the action of the guide groove body (20) and the second protruding shaft (22), the workpiece on the clamping assembly is transferred to the upper part of the transmission assembly after the spiral lifting is firstly carried out, and after the clamping assembly is abutted against the fixing part (33), the workpiece is separated from the clamping assembly, at the moment, the workpiece falls onto the transmission assembly, when the supporting rod (18) moves downwards, the motion is opposite to that when the supporting rod moves upwards, and when the supporting rod (18) descends to the maximum height, the workpiece is clamped;
step three: after the lifting assembly drives the supporting rod (18) to complete one lifting action, the driving assembly drives the transmission assembly to act so as to convey the workpiece;
step four: repeating the steps one to four to finish transferring the workpiece on one production line to another production line.
