[0040] Working principle: A cartridge appearance and thread detection device and detection method thereof have high detection compatibility, stable and accurate positioning, and can realize multi-directional detection. The positioning and clamping of the cartridge are realized by the cooperation of the limit groove and the clamping claw of the driving turntable, and the cartridge to be detected is driven to transfer between different workstations by the rotation of the driving turntable, thereby improving the compatibility of cartridge detection and the stability of transfer detection. Since it is necessary to perform appearance detection on the inside and outside of the cartridge, by setting a detection through hole in the limit groove, it is convenient for the detection structure to detect the internal appearance and thread condition of the cartridge, thereby improving the flexibility and convenience of cartridge detection. The sampling camera that rotates eccentrically can capture images of the inside of the cartridge, providing a viewing angle range for the internal image capture of the cartridge. In addition, the rotation setting facilitates the acquisition of a complete image of the inner wall of the cartridge to avoid detection blind spots. The driving operation of the cartridge is realized by setting a lifting seat 2 and a rotating seat 2 at the bottom to drive the lifting and rotation of the insertion rod, thereby facilitating the fixed outer wall image acquisition probe to collect images of the outer periphery of the cartridge. In addition, the second rotating seat drives the plug rod to cooperate with the clamping claw to realize the release rotation and clamping positioning, which improves the convenience and stability of detection. The cartridge bottom fire hole thread plug gauge through-stop detection mechanism realizes the detection switch of the through gauge detection component and the stop gauge detection component through the double-station alternating mechanism, which further improves the convenience of detection.
