[0020] Please refer to Figure 1-Figure 4 An automatic medicine extraction device comprises an extraction mechanism 1, a frame 2, a placement mechanism 3 and a bottle opening mechanism 4; in the vertical direction, the extraction mechanism 1 and the bottle opening mechanism 4 are sequentially arranged on the frame 2 from top to bottom, and the frame 2 is a horizontally arranged U-shaped structure, a placement cavity 21 is formed in the frame 2, the bottle opening mechanism 4 is arranged in the placement cavity 21, and the extraction mechanism 1 is arranged on the top of the frame 2; the placement mechanism 3 is arranged on one side of the bottle opening mechanism 4 in the horizontal direction, and is arranged opposite to the movable end of the bottle opening mechanism 4; the placement mechanism 3 is provided with a storage space for placing medicine bottles; in the horizontal direction, the medicine extraction end of the extraction mechanism 1 can move relative to the placement mechanism 3 and is arranged opposite to the storage space, and the bottle opening mechanism 4 can gradually approach or gradually move away from the placement mechanism 3.

[0021] It can be understood that by setting up a placement mechanism 3 for fixing the position of the medicine bottle, and setting up a bottle opening mechanism 4, the medicine bottle placed on the placement mechanism 3 is automatically opened, and after opening the bottle, the syringe is controlled by the extraction mechanism 1 to automatically extract the medicine, thereby realizing fully automatic drug extraction. Compared with the existing technology, the automatic bottle opening function is realized, which can further reduce the dependence on manual labor and improve work efficiency.

[0022] In some embodiments, the extraction mechanism 1 includes a first linear motion mechanism 11, a height adjustment mechanism 12 and a pushing mechanism 13; the height adjustment mechanism 12 and the pushing mechanism 13 are respectively installed at the movable end of the first linear motion mechanism 11; in the movable direction of the first linear motion mechanism 11, the pushing mechanism 13 is arranged on the side of the height adjustment mechanism 12 close to the fixed end of the first linear motion mechanism 11; in the vertical direction, the movable end of the pushing mechanism 13 is located above the movable end of the height adjustment mechanism 12; the height adjustment mechanism 12 is used to engage with the syringe, and the pushing mechanism 13 is used to push the piston of the syringe to move. The height of the main part of the syringe is controlled by the height adjustment mechanism 12, so that the needle part of the syringe can be lowered and enter the medicine bottle, and correspondingly, the pushing mechanism 13 can also drive the piston of the syringe to rise and fall, which is used to control the height of the syringe on the one hand, and to control the automatic rise and fall of the piston on the other hand, so as to realize automatic drug extraction. The first linear motion mechanism 11 is used to control the height adjustment mechanism 12 and the pushing mechanism 13 to retract when the medicine is not being drawn, so as to facilitate the loading of the medicine bottle onto the placement mechanism 3, and after the medicine bottle is loaded onto the placement mechanism 3 and opened, control the syringe on the height adjustment mechanism 12 and the pushing mechanism 13 to descend and insert the needle into the medicine bottle to draw the medicine. Specifically, the first linear motion mechanism 11 includes a linear drive member 111 and a support frame 112, the support frame 112 is slidably connected to the top of the frame 2 through a guide rail assembly (not shown in the figure), the linear drive member 111 is connected to the support frame 112, and the height adjustment mechanism 12 is installed on the top of the support frame 112.

[0023] In some embodiments, the height adjustment mechanism 12 includes a height adjustment driving member 121 and a syringe clamping member 122; the fixed end of the syringe clamping member 122 is connected to the movable end of the height adjustment driving member 121, and the clamping end of the syringe clamping member 122 is extended in a direction away from the pushing mechanism 13; in the horizontal direction, the clamping end of the syringe clamping member 122 protrudes outside the height adjustment driving member 121. Specifically, the syringe clamping member 122 includes a first extension member 1221 and a syringe clamping ring 1222, the syringe clamping ring 1222 is installed at one end of the first extension member 1221, and the other end of the first extension member 1221 is connected to the movable end of the height adjustment driving member 121. Preferably, the syringe clamping ring 1222 should be elastic or have telescopic ability to adapt to syringes of different sizes. The setting of the height adjustment driving member 121 is used to control the height of the syringe clamping member 122, and then control the height of the syringe.

[0024] In some embodiments, the pushing mechanism 13 includes a pushing driving member 131 and a piston clamping member 132; the pushing driving member 131 is connected to one side of the height adjustment mechanism 12 through a bracket, and the movable end of the piston clamping member 132 is connected to the movable end of the pushing driving member 131; the clamping end of the piston clamping member 132 is extended in the movable direction of the first linear motion mechanism 11 toward the direction close to the height adjustment mechanism 12, and is arranged opposite to the clamping end of the syringe clamping member 122 in the vertical direction. Specifically, the piston clamping member 132 includes a second extension member 1321 and a piston clamping ring 1322, the piston clamping ring 1322 is connected to one end of the second extension member 1321, and the other end of the second extension member 1321 is connected to the movable end of the pushing driving member 131, and the piston clamping ring 1322 is used to clamp with the piston of the syringe, thereby driving the piston to move, so as to draw the medicine into the syringe. The push drive member 131 and the height adjustment drive member 121 respectively control the movement of different parts of the syringe, which can not only adjust the relative position of the syringe and the medicine bottle, but also realize the automatic extraction of medicine from the syringe.

[0025] In some embodiments, the bottle opening mechanism 4 includes a forward mechanism 41, a breaking mechanism 42 and a cutting mechanism 43; the cutting mechanism 43 is drivingly connected to the movable end of the forward mechanism 41, and the cutting mechanism 43 has a blade 432, which is used to cut the medicine bottle placed on the placement mechanism 3; the breaking mechanism 42 is located above the cutting mechanism 43; in the horizontal direction, the breaking mechanism 42 can move toward or away from the placement mechanism 3. The forward mechanism 41 is set to drive the cutting mechanism 43 to move toward the placement mechanism 3, and contact with the surface of the medicine bottle to partially cut off the neck of the medicine bottle, and then the breaking mechanism 42 extends to apply a pushing force to the head of the medicine bottle, and the placement mechanism 3 will apply a reverse force to the medicine bottle, so that the head of the medicine bottle is broken off, and the broken head will fall into the storage box located outside the placement mechanism 3, so as to collect waste materials. Specifically, the breaking mechanism 42 includes a pressure driving member 421 and a pressure block 422, and the pressure block 422 is arranged at the movable end of the pressure driving member 421.

[0028] In some embodiments, the angle between the placement rack 31 and the placement platform 32 is 80°~90°. Since the bottom of the medicine bottle is usually flat, if the medicine bottle is placed flat, the medicine liquid at the bottom of the medicine bottle cannot be completely extracted. Therefore, the placement rack 31 is tilted to simulate the action of manually extracting the medicine liquid. If the angle is too small, the syringe cannot be inserted into the medicine bottle. If the angle is too large, the medicine liquid cannot be tilted to one side of the medicine bottle. Preferably, the angle is 85°. Specifically, the placement rack 31 includes a third extension member 311 and a medicine bottle clamp ring 312. The third extension member 311 is extended in a direction away from the lifting drive member 33, and the medicine bottle clamp ring 312 is arranged at one end of the third extension member 311.
