When the first sensor The device 246 senses that the tray 7 has reached the accurate position, stops the first motor 231, and then drives the second correction block 26 to move through the second cylinder to drive the limit column to move along the guide hole of the bracket to resist the side of the tray 7, thereby correcting the position of the tray 7. After the position of the tray 7 is corrected, the second correction block 26 retreats and separates from the tray 7, and then the lifting assembly lifts the tray 7 upward, and then the correction member 25 extends to correct the position of the tray 7, so that the tray 7 is positioned at the second step portion 242, and then the detection picking mechanism 3 detects the crystal oscillator placed on the tray 7;

When an unqualified crystal oscillator is detected, the suction nozzle part 36 transfers the unqualified crystal oscillator to the recovery mechanism 6. After all the crystal oscillators placed on the material tray 7 are detected, the fifth motor 42 of the pushing plate mechanism 4 is started to drive the second driving wheel 43 to rotate, thereby driving the second driven wheel 45 to rotate, so as to drive the pushing plate slider 47 to move along the pushing plate track, so that the pushing plate plate 48 pushes the material tray 7 to move toward the storage mechanism 5, thereby transferring the material tray 7 to the storage mechanism 5 for storage.

[0120] The defective crystal oscillator screening device of the present invention positions the material tray 7 through the positioning mechanism 2, so as to facilitate the adjustment of the relative positions of the material tray 7 and the storage mechanism 5 and the relative positions of the material tray 7 and the detection and picking mechanism 3. The crystal oscillator placed on the material tray 7 is detected by the detection and picking mechanism 3. When an unqualified crystal is identified, the unqualified crystal oscillator can be picked out and placed in the recovery mechanism 6 through the suction nozzle 36 of the detection and picking mechanism 3, so as to ensure that after the material tray 7 is transferred to the storage mechanism 5, all the crystal oscillators on the material tray 7 are qualified good products. The material tray 7 is conveniently transferred from the positioning mechanism 2 to the storage mechanism 5 through the tray pushing mechanism 4, so as to improve the transfer efficiency of the material tray 7. The defective crystal oscillator screening device improves the screening efficiency of unqualified crystal oscillators, and at the same time liberates manpower and reduces production costs.
