Abstract

The utility model relates to an inspection device of a quartz crystal resonator, which comprises a first turntable and a plurality of suction nozzles uniformly distributed along the circumferential direction of the first turntable, and the first turntable can rotate around the axis of the first turntable and drives the plurality of suction nozzles to rotate synchronously. The suction nozzle rotates to pass through a first positioning station, a first testing station, a second testing station, a third positioning station and a second detecting station which are sequentially arranged in the rotating direction of the first rotating disc. The positioning mechanism I is used for positioning the quartz crystal resonator positioned on the positioning station I; the testing mechanism I is used for testing electrical parameters of the quartz crystal resonator positioned on the testing station I; the testing mechanism II is used for testing the insulating property of the quartz crystal resonator positioned on the testing station II; the positioning mechanism III is used for positioning the quartz crystal resonator positioned on the positioning station III; the second detection mechanism carries out bottom visual detection on the quartz crystal resonator located on the second detection station. Through the arrangement, manual intervention is not needed, and the detection efficiency and accuracy are greatly improved.
