The docking seat 801 is driven to perform telescopic movement by being provided with a threaded driving structure inside the guide groove 800. The docking seat 801 is provided with a driving shaft 802 penetratingly arranged thereon. The driving shaft 802 is externally provided with a gas bag structure 803 near one end of the bearing seat 500. The gas bag structure 803 comprises a hollow hose 804, a folding air bag one 806 and a folding air bag two 807. The hollow hose 804 is internally provided with an irradiation lamp 805. The folding air bag one 806 is butted at both ends to two hollow hoses 804. The folding air bag two 807 is butted at both ends to the hollow hose 804 and the driving shaft 802 externally.

The other end of the folding air bag three 808 is butted to the outside of the middle section of the folding air bag one 806. The driving shaft 802 is internally butted to the folding air bag two 807 through a thin tube.

At this time, the gas bag structure 803 will limit the medicine bottle, which is used to control the subsequent linkage of the medicine bottle. At the same time, the hollow hose 804 will be tightly attached to the inner wall of the medicine bottle. The irradiation lamp 805 can supplement the light of the medicine bottle, so that the detection head 608 can avoid identifying the lower part when detecting the image of the medicine bottle. Under the action of the gas, scratches and damage can be avoided on the surface of the medicine bottle. The docking seat 801 is assembled with a driving motor 809.

The linkage column 814 links the hinged frame 817. The piston frame 812 telescopically moves. At this time, the piston frame 812 injects the gas in the gas cavity 811 into the thin tube.

[0047] This implementation allows for the following: A medicine bottle is placed on the transfer rack 200, and the bottle to be tested is transferred to the testing mechanism 400 via the position transfer mechanism 300. At this time, the threaded drive structure in the control guide channel 800 controls the docking seat 801 to move towards the medicine bottle. The air bag structure 803 is not yet inflated and can smoothly enter the bottle opening. As the air bag structure 803 gradually extends into the bottle, the spherical disk 815 moves to the inclined section of the extrusion groove 702. Under the action of the elastic element 816, the linkage column 814 can move outward. Under the action of the piston frame 812 and the air chamber 811, the thin tube injects air into the folded airbag 807. Under the action of the folded airbag 808 and the folded airbag 806, the air bag structure 803 inflates as a whole. When the bag structure 803 is fully inserted into the bottle, the spherical disk 815 is at the position of the maximum inner diameter of the extrusion groove 702. At this time, the air bag structure 803 fully expands and restricts the inner wall of the medicine bottle. Under the action of the drive motor 809 and the conveyor belt 810, the drive shaft 802 can be rotated. After the air bag structure 803 is fully expanded, it can cooperate with the guide wheel to drive the medicine bottle to rotate. At this time, the control motor in the drive box 607 drives the gear 605 to rotate. Under the action of meshing with the rack 604, the drive box 607 can move in position. At the same time, under the action of the guide block 606 and the curved groove 603, the drive box 607 can also rotate according to the shape of the medicine bottle when moving in position, so as to better scan and detect the medicine bottle and avoid the situation of inconsistent thickness scanning.
