The first limit block 9 and the second limit block 10 can realize the connection and disconnection of the first branch portion 801 and the second branch portion 802.

[0039] Specifically, the ampoule breaking component includes a cutting motor 14, a fixed cover 15 and a fixed airbag 16. The cutting motor 14 is fixedly connected to the surface of the sliding block 11, and the end of the output shaft of the cutting motor 14 is fixedly connected to the surface of the fixed cover 15. The fixed airbag 16 is fixedly connected to the inner wall of the fixed cover 15, and the interior of the fixed airbag 16 is filled with electrorheological fluid; the surface of the fixed cover 15 is provided with a cutting knife 17 for cutting the ampoule bottle.

[0040] Specifically, the cutting knife 17 is fixedly connected to the surface of the U-shaped rod 18 , the surface of the U-shaped rod 18 is movably sleeved with a limiting cylinder 19 , the limiting cylinder 19 is fixedly connected to the surface of the fixed cover 15 , and the surface of the limiting cylinder 19 is fixedly connected to the first suction pump 20 .

[0041] In this embodiment, the first vacuum pump can be used to achieve contact and separation between the cutting blade 17 and the ampoule, and the rotating motor 101 causes the cutting blade 17 to leave a mark on the surface of the ampoule, which is convenient for subsequent breaking.

[0042] Specifically, the ampoule fixing component includes a limiting tube 21 and a limiting airbag 22. The limiting tube 21 is connected to the connecting plate 4, and the limiting airbag 22 is fixedly connected to the inner wall of the limiting tube 21. The interior of the limiting airbag 22 is filled with electrorheological fluid; the surface of the lifting cylinder 102 is fixedly connected to a fixing plate 23, and the surface of the fixing plate 23 is fixedly connected to a camera 24, and the position of the camera 24 corresponds to the position of the limiting tube 21.

[0043] In this embodiment, the ampoule can be fixed and detached by providing the limiting airbag 22, and the camera 24 can monitor the whole process in real time.

[0044] Specifically, the sterile liquid suction component includes a liquid storage needle tube 25, the inner side wall of the liquid storage needle tube 25 is movably connected with a lifting plug 26, and the top of the liquid storage needle tube 25 is fixedly connected with a second suction pump 27; the surface of the liquid storage needle tube 25 is fixedly connected with a second electric push rod 28, and the surface of the second electric push rod 28 is fixedly connected with a guide rod 29, the guide rod 29 is movably connected to the liquid storage needle tube 25, and the second electric push rod 28 is movably connected to the support plate 2.

[0045] Specifically, a first tilt motor 31 is fixedly connected to the surface of the support plate 2, and the output shaft of the first tilt motor 31 movably passes through the support plate 2 and is fixedly connected to the second electric push rod 28; a second tilt motor 30 is fixedly connected to the surface of the fixed plate 23, and the output shaft of the second tilt motor 30 movably passes through the fixed plate 23 and is fixedly connected to the surface of the limit tube 21.

[0046] In this embodiment, after the ampoule is broken, the telescopic cylinder 3 contracts to reset the second limit block 10, and then the electromagnet thereon is energized, and then the electromagnet 13 on the second limit block 10 is de-energized, and the contraction cylinder extends, so that the sliding block 11 moves upward with the upper end of the broken ampoule.

[0047] The first electric push rod 5 contracts to move the support plate 2 toward the direction close to the fixed rod 103. The guide plate 6 and the guide tube 7 can play a role of guiding and limiting. The support plate 2 stops moving after moving to the specified position. Then the first tilting motor 31 and the second tilting motor 30 are started to rotate the liquid storage needle tube 25 toward the direction of the fixed rod 103, and the ampoule is rotated away from the fixed plate 23. Under the monitoring of the camera 24, the second electric push rod 28 is inserted into the tilted ampoule, the second suction pump 27 is started, and the lifting plug 26 moves upward to suck the sterile liquid into the liquid storage needle tube 25.

[0048] When in use, the rotating motor 101 rotates, which can drive the lifting cylinder 102 to rotate, so that the fixed plate 23 on the lifting cylinder 102 drives the limiting tube 21 to move. After moving to the top of the ampoule, the rotating motor 101 stops rotating. It can make the ampoule move toward the inside of the limiting tube 21 through the external lifting structure, and squeeze each other with the limiting airbag 22. The camera 24 can capture the picture, and the video processing system can process the picture captured by the camera 24 in real time. When the ampoule breaks and leaks out of the limiting tube 21, it stops moving upward. At the same time, the electrorheological fluid in the limiting airbag 22 is energized, and the liquid changes into a solid state, thereby fixing the ampoule.

[0049] Afterwards, the telescopic cylinder 3 contracts, and the sliding block 11 moves downward along the first branch portion 801 of the guide frame 8 under the pulling force of the telescopic cylinder 3. The first limit block 9 automatically moves downward under the action of gravity, and the sliding block 11 drives the cutting motor 14 to move downward, so that the fixed cover 15 can cover the ampoule. When the cutting knife 17 on the fixed cover 15 corresponds to the broken part of the ampoule, the sliding block 11 moves to the bottom and stops moving. After that, the electromagnet 13 on the first limit block 9 is energized and fixed to the first branch portion 801.

[0050] The first vacuum pump inflates the interior of the limiting cylinder 19, so that the U-shaped rod 18 drives the cutting knife 17 to move, so that the cutting knife 17 contacts the broken part of the ampoule, and then the cutting motor 14 drives the fixed cover 15 to rotate, so that the cutting knife 17 cuts on the surface of the ampoule, leaving a broken mark on the ampoule, and then the electrorheological fluid in the fixed airbag 16 is energized, changing from liquid to solid, thereby fixing the ampoule, and the cutting motor 14 stops rotating.

[0051] Before the telescopic cylinder 3 is extended, the electromagnet 13 on the second limit block 10 is powered off. After the telescopic cylinder 3 is extended, the sliding block 11 squeezes the second limit block 10, and the second limit block 10 moves along the second branch portion 802. At the same time, the sliding block 11 is pushed into the second branch portion 802. In this case, the telescopic cylinder 3 is transferred to the ampoule to break the ampoule.

[0052] After the ampoule is broken, the telescopic cylinder 3 contracts to reset the second limit block 10, and then the electromagnet thereon is energized, and then the electromagnet 13 on the second limit block 10 is de-energized, and the contraction cylinder extends, so that the sliding block 11 moves upward with the upper end of the broken ampoule.

[0053] The first electric push rod 5 contracts, causing the support plate 2 to move toward the direction close to the fixed rod 103. The guide plate 6 and the guide tube 7 can play the role of guiding and limiting. The support plate 2 stops moving after moving to the specified position. Then the first tilting motor 31 and the second tilting motor 30 are started, causing the liquid storage needle tube 25 to rotate toward the fixed rod 103, and the ampoule to rotate away from the fixed plate 23. Under the monitoring of the camera 24, the second electric push rod 28 is inserted into the tilted ampoule, the second suction pump 27 is started, and the lifting plug 26 moves upward to suck the sterile liquid into the liquid storage needle tube 25. After the liquid extraction is completed, the liquid storage needle tube 25 is reset, and then the first tilting motor 31 and the second tilting motor 30 rotate and reset the liquid storage needle tube 25 and the ampoule.

[0054] The rotating motor 101 rotates, causing the fixed cover 15 and the limiting cover to move to above the discarded ampoule placement area, the electrorheological fluid in the fixed airbag 16 and the limiting airbag 22 are powered off, the ampoule automatically falls, and the liquid storage needle 25 can transfer the sterile liquid under the action of the first tilting motor 31 and the second electric push rod 28.
