Workpiece feeding system

According to the workpiece feeding system, by arranging the workpiece feeding mechanism, the clamp conveying mechanism, the workpiece positioning mechanism and the workpiece feeding mechanism, full-automatic workpiece feeding and assembling are achieved, the labor cost is reduced, and the production efficiency is improved; workpieces in the vibration disc are conveyed to the workpiece positioning base through the linear feeder and conveyed to the workpiece positioning mechanism through the clamp conveying mechanism, and the linear feeder and the workpiece positioning base can be ensured to be located on the same horizontal line with an output port of the vibration disc at the same time through the arrangement of the first adjusting unit. The situation that the workpiece conveying efficiency is reduced due to the fact that the output port of the vibration disc is not flush with the position between the linear feeder and the workpiece positioning base is avoided; and the second adjusting unit is arranged, so th
