After the test is completed, the blowing port 224 stops outputting gas, and the gas delivery part 24 outputs gas to the ventilation pipe 231. The gas blows air to the other side of the one-way valve through the above-mentioned path. If the air pressure detection device located in the blowing part 221 changes, the sealing of the other side of the one-way valve is unqualified, otherwise it is qualified. The baffle 252 descends, and the magnetic suction part 41 at the end of the push rod of the unloading device 4 adsorbs the material plate 1, and pulls the material plate 1 to move to the detection device 2.
