The air flow will enter the air pump 35 from the first fixed groove 3, the air inlet groove 31, the second fixed groove 34, the connecting hose 32, the air inlet pipe 33 in sequence. At this time, the circuit board will be limited on the surface of the test table 12 by suction to achieve the purpose of fixing and limiting the circuit board. When the circuit board is sealed with glue, the power of the fan motor 42 can be turned on first. At this time, the fan motor 42 will drive the first rotating shaft 43 and the fan blades 44 to start rotating in sequence. At this time, the fan blades 44 will blow air to the circuit board below to achieve In order to accelerate the solidification of the glue, when the glue needs to be cooled faster, the guide plate 51 can be moved to adjust its angle first.
