For example, if the workpiece to be tested is cigarette popping beads, the unqualified workpiece may be cigarette popping beads with defects such as irregular bubbles, empty pellets, solids, spots, oversize, undersize, roundness, tailing and other defects.

The upper detection mechanism 41 is mainly used to detect the workpiece 101 to be tested from above; the lower detection mechanism 42 is mainly used to detect the workpiece 101 to be tested from below.

Specifically, the number of air blowing pipes is the same as the number of adsorption heads 331, which are installed at the removal position of the removal mechanism 43 and higher than the adsorption heads 331. When the adsorption head 331 of the transfer mechanism 31 drives the blasting beads to the removal position, the blowing pipes are blown. The air pipe is located just above the workpiece 101, and the unqualified workpiece 101 will be blown and rejected.
