Both ends of the carrier box 7 are rotatably connected with a turntable frame 38, and the two turntable frames 38 are respectively fixedly connected with two connecting springs 6, and the overall center of gravity of the carrier box 7 is located on the lower side of its central axis, so the upward state of the take-in and put-out opening 8 on the carrier box 7 can be better maintained.

[0024] The electromagnet 3 in this embodiment is a conventional device well-known to those skilled in the art and purchased on the market. Other models can also be selected or customized according to actual needs. In the present invention, we only use it and do not improve its structure and function. For those skilled in the art, its setting method, installation method, and electrical connection method can be debugged and operated as long as the requirements of its user manual are followed, and no further elaboration will be made here.

[0025] In summary, the working principle of the pharmacy drug delivery device and method is as follows: during use, first, the top opening member 1 in the drug placement mechanism is fixedly placed near the drug storage location, and then the top opening member 1 in the drug retrieval mechanism is fixedly placed near the drug retrieval location. Then, the communication between the two top opening members 1 is achieved through the fine adjustment tube 2. Next, the sequential electrical installation of multiple electromagnets 3 is completed. There is a power connection line along the fine adjustment tube 2 and the top opening member 1, and this power connection line is equipped with a plug. The electrical installation of multiple electromagnets 3 can be completed by inserting and electrically connecting with an external power supply socket. Debug the multiple electromagnets 3 to make there be a turn-on delay between the multiple electromagnets 3, that is, the multiple electromagnets 3 can be powered on in sequence and form electromagnetic fields in sequence. Since the fine adjustment tube 2 has a certain flexibility and can be bent appropriately, it can better adapt to the installation and layout between the drug storage location and the drug retrieval location. During the actual use process, the position of the fixedly placed top opening member 1 can be changed according to specific situations, so as to achieve the corresponding adjustment of the drug delivery target point and the drug delivery start point. During the operation process, the electromagnetic fields generated by the sequential power-on of multiple electromagnets 3 act on the iron column 5. Due to the relative magnetic traction effect of the electromagnetic field on the iron column 5, the carrier box 7 will move in the top opening member 1 and the fine adjustment tube 2. As shown in the Figure 15 figure. In the upper figure, one electromagnet 3 in the lower left is in the powered-on state. At this time, the powered-on electromagnet 3 pulls one iron column 5 on the left, causing one iron column 5 on the left to push the left moving frame 4 to move to the right. And under the action of the connecting spring 6, it forms an auxiliary push on the carrier box 7 to the right. Multiple electromagnets 3 are powered on in sequence to form an auxiliary magnetic force traction on one iron column 5 on the left. As shown in the Figure 15 figure. In the lower figure, one electromagnet 3 in the lower right is in the powered-on state. At this time, the powered-on electromagnet 3 pulls one iron column 5 on the right, causing one iron column 5 on the right to pull the right moving frame 4 to move to the right. And under the action of the connecting spring 6, it forms an auxiliary pull on the carrier box 7 to the right. Control the sequential power-on of multiple electromagnets 3 to form an auxiliary magnetic force traction on one iron column 5 on the right. There is a certain time overlap between the two electromagnets 3 powered on in sequence, that is, the previously powered-on electromagnet 3 needs to wait until the next electromagnet 3 is powered on to generate an electromagnetic field before it will power off. In this way, the position control of the carrier box 7 in the top opening member 1 and the fine adjustment tube 2 can be achieved.

[0026] Further, after the carrier box 7 enters the top opening member 1, due to the coupling and linkage effect of the external door assembly and the normally closed door assembly, when the external door assembly is opened, the normally closed door assembly will also be synchronously opened. Manually controlling the rotation and opening of the first rotating door 24 will form an auxiliary push on the first push frame 29. Under the action of the linkage frame 28 connected to the first push frame 29, the first push frame 29 will move downward in parallel with the fixed parallel plate 27. The downward-moving first push frame 29 will drive the first round head extension plate 31 to form an auxiliary push on the first arc-shaped door 20, so that the first arc-shaped door 20 rotates and opens. Moreover, when the first rotating door 24 opens, it will drive the first linkage rod 33 to move. The movement of the first linkage rod 33 will drive the transmission frame 34 to rotate. The rotation of the transmission frame 34 forms the rotation and opening of the second rotating door 25 through the second linkage frame 28, that is, the synchronous relative rotation and opening of the first rotating door 24 and the second rotating door 25 are formed. The opened second rotating door 25 realizes the downward push of the second round head extension plate 32 through the second push frame 30, and finally realizes the rotation and opening of the second arc-shaped door 21. After the normally closed door assembly is opened, the operation of putting in and taking out drugs can be performed relative to the carrier box 7. That is, if the corresponding opened external door assembly is the external door assembly in the drug loading mechanism, the drug can be put into the carrier box 7. If the corresponding opened external door assembly is the external door assembly in the drug taking mechanism, the drug can be taken out relative to the carrier box 7.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
