If it is determined that the assembly is incorrect, the NG prompt light will light up, prompting the worker that the disc spring assembly being tested is a defective product, and then the X-axis module 21 drives the manual loading platform 26 to drive the jig When the disc spring assembly in 27 moves to the bottom of the height detection platform 22, the height detection platform 22 is driven to move the height detector 29 downward by starting the Y-axis module 23 to measure the height dimension of the disc spring assembly. When the height detector 29 detects that the disc spring assembly being tested is a defective product, the NG prompt light will also light up. After the inspection is completed, the X-axis module 21 drives the manual loading platform 26 to drive the disc spring assembly in the jig 27 to move to the outside of the inspection housing 11.
