[0030] Working principle: Firstly, after starting the device, the control box is electrically connected with the conveyor 4, the driving motor, the photoelectric sensor, the telescopic cylinder 74 and the driving cylinder 92. The operator places the bottle body 8 on the mounting plate 76 of the anti-inclination mechanism 7 one by one. After the photoelectric sensor inside the mounting plate 76 detects the bottle body 8, a signal is sent to the control box. The telescopic cylinder 74 is started and drives the telescopic shaft 75 to shrink the mounting plate 76 downward. The limiting clamping jaw 77 at the upper end of the mounting plate 76 is connected with the first bearing seat 731 and the second bearing seat 761 on the mounting frame 73 through the connecting rod 78, forming a connecting rod mechanism. Under the action of the telescopic cylinder 74, the positioning pad 79 on the limiting clamping jaw 77 flexibly clamps the bottle body 8, and the positioning pad 79 flexibly clamps the middle part of the bottle body 8, ensuring that the bottle body 8 remains upright during the conveying process. Secondly, when the bottle body 8 moves to the area of the guide mechanism 5, the lower limiting plate 51 and the upper limiting plate 52 form a vertical limiting channel. The auxiliary pulley 53 inside the upper limiting plate 52 rolls against the upper end face of the bottle body 8, reducing the conveying friction. The driving motor in the sorting and mounting box 2 drives the rotating shaft 54 to rotate, thereby driving the lower star-shaped pulley 61 and the upper star-shaped pulley 63 of the sorting mechanism 6 to rotate synchronously. The clamping groove 611 of the upper star-shaped pulley 63 is clamped with the sliding groove 72 of the mounting base 71 through the clamping pad 613. The clamping groove 611 of the lower star-shaped pulley 61 clamps the bottle body 8. The buffer spring 612 and the flexible clamping pad 613 in the clamping groove 611 absorb the impact force to avoid damage to the bottle body 8. The anti-inclination mechanism 7 always maintains the clamping state to prevent the bottle body 8 from tilting during the sorting process. Finally, the sorted bottle body 8 reaches the corresponding station of the feeding mounting box 3 with the conveyor 4. The control box sends a signal to the feeding mechanism 9. The driving cylinder 92 is started and pushes the multi-station feeding seat 93 to move towards the bottle body 8. The bottle port positioning clamping jaw 96 at the lower end of the filling pump 94 accurately clamps the port of the bottle body 8. The telescopic spring 97 between the multi-station feeding seat 93 and the filling pump 94 buffers the vibration to ensure the stable positioning of the bottle body 8. Then the filling pump 94 is started to extract the liquid medicine from the liquid storage box 95 through the liquid medicine pipeline 951 and accurately inject it into the bottle body 8 through the filling needle 952. During the whole process, the control box accurately controls the cooperative work of the conveyor 4, the driving motor, the telescopic cylinder 74 and the driving cylinder 92 according to the data feedback by the photoelectric sensor, realizes the accurate positioning, sorting and filling of the bottle body 8, and guarantees the continuity and stability of the production.
