[0039] The above-mentioned new type of injection distribution mechanism realizes the storage and automatic distribution of one or more injection medicines by arranging a plurality of storage and distribution small drawers 3 in the drawer body 1, and arranging the distribution conveying belt 4 and the conveying belt driving assembly 5 arranged in the storage and distribution small drawer 3, solves the deficiency of the existing automatic medicine dispensing machine in the distribution of injection medicines, expands the application range of the automatic medicine dispensing machine, and makes it more fully meet the needs of the hospital pharmacy; by arranging a plurality of storage and distribution small drawers 3 side by side, the space in the drawer body 1 is effectively utilized, so that the mechanism can store more medicines in a limited volume, saving the space resources of the pharmacy; the overall structure is compact, which is not only convenient for installation and maintenance, but also convenient for integration in the automatic medicine dispensing equipment, and does not occupy too much internal space of the equipment.

[0040] Please refer to Figure 6 In an embodiment, the outer surface of the distribution conveying belt 4 is sleeved with a medicine storage sponge 6 and is adhesively fixed with the medicine storage sponge 6, and the outer surface of the medicine storage sponge 6 is uniformly provided with a plurality of medicine storage grooves 601. The softness and elasticity of the medicine storage sponge 6 can effectively protect the injection medicine, reduce the collision and friction of the injection medicine during conveying, and prevent the injection medicine from being damaged or the label from being worn. The adhesively fixed medicine storage sponge 6 and the distribution conveying belt 4 ensure the stability of the medicine storage groove 601 during conveying, and reduce the risk of sliding or falling of the injection medicine during movement.

[0041] Please refer to Figure 6In one embodiment, the medicine storage groove 601 is in a U shape. The U-shaped groove forms a certain block on both sides of the injection medicine, effectively preventing the injection medicine from falling out of the groove during the rotation of the dispensing conveyor belt 4, improving the reliability of the dispensing, and ensuring that the injection medicine in the medicine storage groove 601 can smoothly fall under the action of gravity when the medicine storage groove 601 is driven to rotate downward by the dispensing conveyor belt 4. In addition, the U-shaped groove can be arranged more compactly on the dispensing conveyor belt 4, thereby accommodating more medicines in a limited space and improving the space utilization.

[0042] Please refer to Figure 5 , Figure 6 In one embodiment, the conveyor belt driving assembly 5 includes a driving motor 501, a transmission gear 502, a driving shaft 503, and a driven shaft 504. The driving motor 501 is fixed to one of the side plates of the storage and dispensing small drawer 3 and located inside the dispensing conveyor belt 4. The driving shaft 503 and the driven shaft 504 are movably installed between the two side plates of the storage and dispensing small drawer 3 through a bearing seat 505. The driving motor 501 is in transmission connection with the driving shaft 503 through the transmission gear 502. The dispensing conveyor belt 4 is sleeved on the driving shaft 503 and the driven shaft 504, forming a closed conveying path, so that the dispensing conveyor belt 4 can run smoothly and continuously. The above-mentioned conveyor belt driving assembly 5 has a very compact structure, fully utilizes the internal space of the storage and dispensing small drawer 3, and improves the space utilization and the integration of the system. In addition, the bearing seat 505 not only adjusts the tension of the dispensing conveyor belt 4, but also facilitates the disassembly and assembly of the driving shaft 503 and the driven shaft 504.

[0043] Please refer to Figure 4 , Figure 5 In one embodiment, a pair of opposite radiation sensors 7 for counting is arranged outside the two side plates of the storage and dispensing small drawer 3. One of the opposite radiation sensors 7 is a transmitter and the other is a receiver. First sensing avoidance openings 302 are formed on the two side plates of the storage and dispensing small drawer 3 corresponding to the positions of the opposite radiation sensors 7. The first sensing avoidance openings 302 allow the light emitted by the transmitter to pass through and reach the receiver, so as to ensure that the opposite radiation sensors 7 can accurately detect the passage of the medicine storage groove 601 without affecting the normal operation of the dispensing conveyor belt 4. With the rotation of the dispensing conveyor belt 4, the medicine storage groove 601 located at the lower part of the conveyor belt will pass through the detection area of the opposite radiation sensors 7 in turn. When the medicine storage groove 601 blocks the light of the transmitter, the opposite radiation sensors 7 will output a trigger signal, indicating that a medicine storage groove 601 has passed through the detection area. By recording the number and time interval of these trigger signals, the position and number of the medicine storage groove 601 on the dispensing conveyor belt 4 can be accurately calculated, thereby realizing accurate control of the medicine dispensing process.

[0044] Specifically, the opposite sensors 7 are fixed outside the side plates of the storage and dispensing small drawers 3 by the sensor supports 8. Since the opposite sensors 7 are installed outside the storage and dispensing small drawers 3, they are relatively easy to access and maintain. If it is necessary to replace or upgrade the sensors, it is only necessary to simply disassemble and reassemble, without the need to disassemble and reassemble the entire dispensing system. In addition, being fixed outside the side plates of the storage and dispensing small drawers 3 does not occupy the internal space of the storage and dispensing small drawers 3, and can make the structure of the storage and dispensing small drawers 3 more compact.

[0045] Referring to Figures 3 to 5 In an embodiment, the inside end side of the drawer body 1 is provided with a medicine dropping sensor 9, and the two side plates of the storage and dispensing small drawer 3 are provided with second sensing avoidance openings 303 corresponding to the positions of the medicine dropping sensor 9. The second sensing avoidance openings 303 ensure that the medicine dropping sensor 9 is not blocked by the side plates of the storage and dispensing small drawer 3, and can accurately detect the falling of the injection medicine from the inside of each storage and dispensing small drawer 3, ensuring the accuracy and timeliness of the dispensing process.

[0046] Referring to Figure 1 , Figure 5 , Figure 7 In an embodiment, the top of the storage and dispensing small drawer 3 is provided with a small drawer cover plate 10 that can slide forward and backward to open or close the storage and dispensing small drawer 3. The small drawer cover plate 10 is provided so that when the storage and dispensing small drawer 3 is closed, it can effectively prevent dust, moisture or other contaminants from entering the inside of the drawer, and to some extent reduce the occurrence of misoperation and improve the safety of the drawer. Since the cover plate needs to be slid to open the drawer, the staff will be more careful when operating, avoiding mistakes such as adding the wrong medicine, spilling or damaging the medicine. The sliding of the small drawer cover plate 10 makes it easier and faster to open and close the drawer, and the staff only needs to simply slide the cover plate to complete the operation, without the need to lift or close the entire drawer, thereby improving the work efficiency and the convenience of operation.

[0047] Specifically, the top of the storage and distribution small drawer 3 is provided with a limiting strip 304 on both sides of the opening to limit the front and back sliding of the small drawer cover plate 10, avoiding the left and right shaking of the small drawer cover plate 10 when sliding forward and backward. The top end of the small drawer cover plate 10 is provided with a first lock catch 11, and the top end of the storage and distribution small drawer 3 is provided with an electromagnetic lock fixing plate 12. The end of the electromagnetic lock fixing plate 12 is provided with a first electromagnetic lock 13 corresponding to the position of each storage and distribution small drawer 3, which cooperates with the first lock catch 11. By controlling the on-off state of the first electromagnetic lock 13, the system can accurately unlock the small drawer cover plate 10 of each storage and distribution small drawer 3 when adding medicine, preventing the medicine adding personnel from putting the medicine into the wrong medicine storage groove 601. When the small drawer cover plate 10 slides to the closed position, the first lock catch 11 can cooperate with the corresponding first electromagnetic lock 13 to firmly lock the small drawer cover plate 10 in the closed state, ensuring that the small drawer cover plate 10 will not be accidentally opened due to vibration or bumping during the pulling process, and also effectively preventing unauthorized personnel from accessing the inside of the drawer, thereby enhancing the safety of the drawer.

[0048] In addition, the top of the first lock catch 11 is higher than the electromagnetic lock fixing plate 12, and the top side of the first lock catch 11 is provided with a pulley 14, which cooperates with the linear slide rail arranged at the medicine adding opening of the automatic medicine dispensing equipment, further limiting the front and back sliding of the small drawer cover plate 10. By designing the top of the first lock catch 11 to be higher than the electromagnetic lock fixing plate 12, this design ingeniously uses the spatial position relationship to enhance the stability and accuracy of the front and back sliding of the small drawer cover plate 10. When the small drawer cover plate 10 is in the closed state, the first lock catch 11 not only cooperates with the first electromagnetic lock 13 to achieve locking, but also provides a certain support force for the small drawer cover plate 10 through the cooperation of the pulley 14 and the linear slide rail, reducing the friction and resistance in the sliding process, and preventing the end of the small drawer cover plate 10 from being suspended, tilted or shaken during the front and back sliding process.

[0049] Please refer to Figure 7 In an embodiment, the front end of the small drawer cover plate 10 is provided with a pulling hole 1001. The pulling hole 1001 provides a visual and easy-to-operate handle position for the medicine adding personnel. The medicine adding personnel can easily pull the small drawer cover plate 10 forward and backward through the pulling hole 1001 to open or close the storage and distribution small drawer 3, without the need to find other difficult-to-identify operation points.

[0050] In an embodiment, the material of the small drawer cover plate 10 is transparent. The transparent small drawer cover plate 10 allows users to directly observe the storage and distribution small drawer 3 inside the small drawer cover plate 10 without opening the small drawer cover plate 10, without the need to frequently open the small drawer cover plate 10.

[0051] Please refer to Figure 1 ,Figure 2 In one embodiment, the side plate end of the drawer body 1 is provided with a second electromagnetic lock 15, which cooperates with a second lock buckle provided at the medicine adding opening of the automatic medicine dispensing device to lock the drawer body 1. The second electromagnetic lock 15 can effectively prevent unauthorized personnel from accessing the inside of the drawer, thereby enhancing the security of the drawer and helping to enhance the stability of the drawer body 1 in the automatic medicine dispensing device. When the drawer body 1 is locked, the magnetic force generated by the second electromagnetic lock 15 can ensure that the drawer body 1 does not accidentally slide out or loosen during the movement or vibration of the dispensing conveyor belt 4, thereby ensuring the normal operation of the device and the safe dispensing of medicines.

[0052] Please refer to Figure 1 In one embodiment, the front end of the drawer body 1 is provided with a medicine adding indicator light 16 corresponding to the position of each storage and dispensing small drawer 3. The medicine adding indicator light 16 can directly display the medicine adding state of each storage and dispensing small drawer 3. When one storage and dispensing small drawer 3 needs to be added, the corresponding indicator light will light up to remind the staff to add medicine in time.
