secondly, the feeding power element drives the workpiece in the transition hole (6-3-1) of the sliding plate (6-3) to move to the position above the discharge hole at the outer end of the sliding frame (6-1) and fall into a workpiece storage block (5) positioned at a workpiece feeding station through the discharge hole; then, the feeding power element is reset, so that the next workpiece in the feeding hole (6-4-1) enters the transition hole (6-3-1);
each first optical fiber sensor (6-7) respectively detects whether the corresponding transition hole (6-3-1) obtains the workpiece from the feeding hole (6-4-1) or not and whether the workpiece smoothly leaves the transition hole (6-3-1) or not; each second optical fiber sensor (6-8) respectively detects whether the corresponding discharge hole outputs the workpiece to a material mounting position; if the workpiece is clamped at the transition hole (6-3-1) and the discharge hole or is not flatly placed at the material placement position, the air blowing piece blows air, and the hammering cylinder stretches and retracts for multiple times to generate vibration, so that the clamped workpiece moves and correctly falls into the workpiece storage block (5);
and step three, moving an empty workpiece storage block (5) to the lower part of each discharge hole.
