The first camera 18 transmits the image it takes to the control system. The control system can compare the image taken by the first camera 18 with the pre-stored standard image of the bottle bottom to determine whether there is a defect in the bottle bottom. When inspecting the bottom of the bottle, the first gripper 16 grasps the medicine bottle on the inspection turntable 2 that has reached the bottom inspection position. Then, the first lifting drive device 14 drives the first lifting frame 12 to rise and raise the medicine bottle until it is detached from the medicine bottle slot. Then, the first horizontal drive device 15 drives the first horizontal telescopic frame 13 to slide horizontally, so that the bottom of the medicine bottle is facing the first light source 17 and the first camera 18. The first light source 17 illuminates the bottom of the bottle, and the first camera 18 takes a picture of the bottom of the bottle.

[0025] When the medicine bottle reaches the detection position on the outer wall of the bottle mouth, the second gripper 20 extends and grabs the body of the medicine bottle. Then, the second lifting frame 21 descends so that the position of the roller 29 is directly opposite the outer wall of the bottle mouth. Then, the pushing device 30 releases the sliding rod 27. Under the elastic force of the elastic element 28, the sliding rod 27 moves towards the inside of the bottle mouth, so that the roller 29 is pressed against the lower edge of the outer wall of the bottle mouth. Then, the first rotary drive device 24 starts to drive the first rotary shaft 23 to rotate. The roller 29 rolls one revolution along the outer wall of the bottle mouth. During the rolling process, if there is a pit in the bottle mouth, the sliding rod 27 will slide radially along the bottle mouth. This will cause the first trigger device 26 to trigger the first sensing device 25. The control system will then determine that the outer wall of the bottle mouth is unqualified. Otherwise, this station will determine that the outer wall of the bottle mouth is qualified.
