Description

Technical Field

[0001] This invention belongs to the field of drug classification management, specifically a drug classification management device for hospital pharmacies. Background Technology

[0002] Drugs refer to substances used to prevent, treat, or diagnose human diseases, or to purposefully regulate human physiological functions, and which have specified indications or functions, usage, and dosage. They include Chinese medicinal materials, prepared slices of Chinese medicinal herbs, prepared Chinese medicines, chemical raw materials and their preparations, antibiotics, biochemical drugs, radioactive drugs, serums, vaccines, blood products, and diagnostic drugs, etc.

[0003] Hospitals store their medicines in pharmacies, but the number of medicines in a pharmacy is large. In order to ensure the orderly dispensing and storage of medicines, it is necessary to set up a medicine classification and management device to separate the medicines and manage their storage location and quantity.

[0004] Hospital pharmacies have a large number of medicines. In order to ensure convenient access to medicines, they need to be classified and placed on designated medicine shelves. When taking medicines, they need to be taken manually. After a period of time, medicines also need to be replenished manually. Relying too much on manual labor is not only prone to errors, but also consumes a lot of human resources.

[0005] Therefore, the present invention provides a drug classification and management device for hospital pharmacies. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A hospital pharmacy drug classification and management device includes multiple classification storage cabinets, a transport vehicle, and magnetic strips. The magnetic strips are attached to the ground. Electric wheels and AGV navigation equipment are installed at the bottom of both the transport vehicle and the classification storage cabinets. A storage slot is opened at the front of the classification storage cabinet, and multiple arrangement boxes are arranged inside the storage slot. A scissor-type drive module is fixedly installed on one end of the inner side of each arrangement box. A recessed groove is opened on the top surface of the transport vehicle, and a drug placement component is arranged inside the recessed groove. The drug placement component is used to place the drugs in the recessed groove into the arrangement boxes. During operation, hospital pharmacies have a large number of drugs. To ensure convenient drug retrieval, drugs need to be classified and placed on designated drug shelves. Drugs are then retrieved manually, and replenishment is required manually after a period of time. This reliance on manual labor is not only prone to errors but also consumes a lot of human resources. By setting up the transport vehicle, magnetic strips are first attached to the bottom surface of the pharmacy to guide the AGV navigation equipment through the classification storage cabinets. Different types of Chinese medicines are categorized and stored using drive wheels and AGV navigation equipment. The categorized storage cabinets are moved to designated locations within the pharmacy, where the temperature and humidity are suitable for storing the medicines. When retrieving medicine, the corresponding scissor-drive module is activated to push the medicine out of the tiered box. Before pushing, a transport vehicle, guided by the AGV navigation equipment and electric wheels, moves below the tiered box, allowing the medicine to fall into the recessed slot. After all medicines are retrieved, the transport vehicle moves to the retrieval port for manual verification. Once verified, the medicines are retrieved. When replenishment is needed, a batch of neatly arranged medicines is placed on the medicine dispensing assembly. The transport vehicle then moves to the corresponding tiered box, and the dispensing assembly places the medicine into the box. This setup achieves mechanical medicine retrieval, storage, and directional movement of the categorized storage cabinets, significantly reducing manual labor. The purely mechanical operation and final manual verification also minimize errors. The scissor-drive module includes two folding frames and an electric lever. Pulling the bottom of the folding frames causes them to fold together, extending them to complete the ejection process.

[0008] Preferably, a scissor-drive module two is fixedly installed on the inner bottom surface of the recessed groove. A tray is fixedly installed on the top of the scissor-drive module two. One side of the tray is open, and a servo motor is fixedly installed on one side of the tray. A baffle is fixedly installed on the output end of the servo motor. Multiple scissor-drive modules three are fixedly installed on the side of the tray away from the baffle. During operation, the missing medicines are neatly arranged on the tray. The scissor-drive module three is activated to push the medicines against the baffle, reducing the shaking of the medicines during movement. When the medicines are moved to the outside of the corresponding arrangement box, the scissor-drive module two is activated to raise the tray to the corresponding height. Then, the servo motor is activated to raise the baffle, allowing the medicines to be neatly pressed into the arrangement box under the push of the scissor-drive module three, thereby achieving stable medicine replenishment.

[0009] Preferably, a fixing frame is fixedly installed at the front end of the arrangement box, and an outer sleeve is rotatably connected to the outside of the fixing frame. A blocking plate is fixedly installed on the outside of the outer sleeve. The blocking plate is made of elastic material, and multiple detection strips are fixedly installed on the outside of the blocking plate. A detection positioning module is fixedly installed at the bottom end of the arrangement box. During operation, the blocking plate can seal the end of the arrangement box, allowing the medicine to be subjected to a certain resistance when it is discharged. When one medicine is pushed out, the next medicine will be pressed down by the elastic blocking plate, reducing the problem of multiple medicines being squeezed out. The detection positioning module and detection strips will cause the blocking plate and detection strips to move away from the detection positioning module whenever a medicine is pushed out. When the medicine is completely pushed out, the blocking plate will return under its own elasticity, and the detection strips will contact the detection positioning module again. At this time, the detection positioning module will count and transmit the count information outward, thereby accurately determining the number of medicines discharged and knowing the remaining space in the arrangement box. At the same time, the detection positioning module also has a positioning signal sending function to guide the tray to rise to a specified height, ensuring the accuracy of filling medicines.

[0010] Preferably, the inner wall of the bottom surface of the tray has two rows of sliding grooves, and two symmetrically arranged center plates are slidably connected to the top surface of the sliding grooves. A power component is fixedly connected between the center plates and the tray. The power component is used to push the center plates to slide. During operation, in order to ensure that the medicine is aligned with the arrangement box when the medicine is placed in the tray, the power component is activated to drive the two center plates to squeeze towards the center. With the compression of the scissor drive module, the baffle and the two center plates, the medicine is squeezed from four directions, further reducing the problem of medicine displacement and filling errors when the transport vehicle moves.

[0011] Preferably, the power assembly includes an elastic bladder, which is fixedly connected between the center plate and the inner wall of the tray. Two sets of air pressure assemblies are fixedly installed in the inner wall of the tray, and the two sets of air pressure assemblies are arranged symmetrically. The air pressure assemblies include a negative pressure unit and a blower. Both the negative pressure unit and the blower are connected to the inner side of the elastic bladder. Two sets of springs are fixedly connected between the center plate and the tray. The springs are located inside the elastic bladder. During operation, when the medicines are placed into the tray in rows, the blower is activated to press air into the elastic bladder, causing the elastic bladder to expand laterally, thereby pushing the center plate to move. After the compression is completed, the negative pressure unit is activated to extract the air. With the compression of the springs, the center plate returns to its original position. This arrangement makes the space occupied by the center plate after it is retracted smaller. Compared with structures such as electric telescopic rods, it can reserve a larger space for placing medicines on the tray. The thrust of the scissor-type drive module three is small. It can push the medicines but will not crush the elastic bladder. In addition, the arrangement of the two sliding grooves makes the movement of the center plate stable.

[0012] Preferably, the outer sleeve has a through groove extending to the inner cavity at the middle of its outer side. A stop bar is fixedly installed on the outer side of the fixing frame. The stop bar passes through and slides through the through groove. During operation, with the through groove and stop bar in place, when the medicine is extruded and arranged in the box, the outer sleeve is blocked by the stop bar and cannot rotate outward. This allows the elastic potential energy of the blocking plate to be fully applied to the medicine, reducing the problem of excess medicine falling off. When the medicine is replenished, the outer sleeve can rotate counterclockwise without the stop bar blocking it, and the blocking plate will not deform. After the medicine is dispensed, the blocking plate will return to its original position under the action of gravity. This design reduces the deformation frequency of the blocking plate and increases its service life.

[0013] Preferably, the inner side of the storage slot is rotatably connected to multiple transmission rods, and the end of each transmission rod is fixedly mounted with a drive motor. The drive motor is fixedly connected to the classification storage cabinet, and the outer side of each transmission rod is fixedly connected to the bottom surface of the arrangement box. During operation, when replenishing medicines, the drive motor is started to drive the transmission rods and the arrangement box to rotate to a horizontal state. After replenishment is completed, the drive motor is turned off, and the end of the arrangement box sinks under the action of gravity, causing the arrangement box to tilt and allowing the medicines to slide down to the end of the scissor-type drive module under the action of gravity. This setting allows the medicines to be arranged more neatly and can assist in the medicine ejection process.

[0014] Preferably, the inner wall of the storage tank has multiple unit slots, which are vertical and correspond to multiple arrangement boxes. A straight rod is fixedly installed at the end of each arrangement box away from the blocking plate. The straight rod is slidably connected to the unit slot. During operation, the arrangement of the unit slots and the straight rod allows the end of the arrangement box to have a force point after tilting, ensuring the stability of the arrangement box. After the medicine is applied, the drive motor can be started multiple times to make the arrangement box repeatedly tilt and swing upward, thereby generating vibration. Under the action of vibration and gravity, the medicine is arranged neatly, effectively assisting in the medicine ejection process.

[0015] Preferably, the inner wall of the recessed groove has an annular groove near its top surface. A sliding rod is slidably connected to the inner side of the annular groove. A blocking curtain is fixedly connected between the sliding rod and the inner wall of the recessed groove. A power component is provided on the outer side of the sliding rod. The power component is used to drive the sliding rod to slide. The blocking curtain is made of flexible material. During operation, when receiving the ejected medicine, the power component is activated to drive the sliding rod to slide from the annular groove, allowing the flexible blocking curtain to block the opening of the recessed groove. This allows the falling medicine to be caught by the flexible blocking curtain, reducing damage to the medicine. Furthermore, the flexible blocking curtain is not elastic and will not rebound, causing the medicine to fly out.

[0016] Preferably, the power assembly includes two symmetrically arranged drive boxes, which are fixedly connected to the outer wall of the transport vehicle. A motor is fixedly installed inside the drive box, and a connecting rope is wound around the output end of the motor. The two ends of the connecting rope pass through an annular groove and are fixedly connected to the two ends of a sliding rod. A magnet is fixedly installed in the middle of the barrier curtain. The transport vehicle is made of magnetic metal. When it needs to be unfolded during operation, one of the motors is started to wind the connecting rope, thereby pulling the sliding rod and allowing the barrier curtain to seal the recessed groove. After the medicine is removed, the other motor is started to rewind the other connecting rope, which can pull the sliding rod to move in the opposite direction, allowing the barrier curtain to fold. With the magnet, the folded barrier curtain can be magnetically attracted to the inner wall of the transport vehicle.

[0017] The beneficial effects of this invention are as follows:

[0018] The present invention discloses a hospital pharmacy drug classification and management device, which achieves the effects of mechanical drug retrieval, storage, and directional movement of classification and storage cabinets through a transport vehicle, magnetic strips, and classification storage cabinets, greatly reducing manual labor. At the same time, the purely mechanical operation and the final manual verification also reduce the occurrence of errors. The scissor-drive module includes two folding frames and an electric pull rod. By pulling the bottom end of the folding frame, it is brought together, allowing the folding frame to unfold and lengthen, thereby completing the ejection operation.

[0019] The hospital pharmacy drug classification and management device described in this invention, in conjunction with the setting of a blocking plate, can seal the end of the arrangement box, allowing the drugs to be discharged with a certain resistance. When one drug is pushed out, the next drug will be pressed down by the elastic blocking plate, reducing the problem of multiple drugs being squeezed out. The setting of the detection and positioning module and the detection strip, whenever a drug is pushed out, will cause the blocking plate and the detection strip to move away from the detection and positioning module. When the drug is completely pushed out, the blocking plate will return under its own elasticity, and the detection strip will come into contact with the detection and positioning module again. At this time, the detection and positioning module will count and transmit the count information outward, thereby accurately determining the number of drugs discharged and knowing the remaining space in the arrangement box. At the same time, the detection and positioning module also has a positioning signal sending function to guide the tray to rise to a specified height, ensuring the accuracy of filling drugs.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1

[0031] like Figures 1 to 7 As shown in the embodiment of the present invention, a hospital pharmacy drug classification and management device includes multiple classification storage cabinets 1, a transport vehicle 2, and magnetic strips 3. The magnetic strips 3 are in contact with the ground. The bottom ends of the transport vehicle 2 and the classification storage cabinets 1 are equipped with electric wheels and AGV navigation equipment. The front end of the classification storage cabinet 1 has a storage slot 4. The inner side of the storage slot 4 is provided with multiple arrangement boxes 5. A scissor-type drive module 7 is fixedly installed on one end of the inner side of the arrangement box 5. The top surface of the transport vehicle 2 has a recessed groove 14. The inner side of the recessed groove 14 is provided with... The pharmacy is equipped with a drug dispensing assembly, which is used to place the drugs in the recessed slot 14 into the arrangement box 5. During operation, the hospital pharmacy has a large quantity of drugs. To ensure convenient drug retrieval, the drugs need to be categorized and placed on designated drug shelves, and then manually retrieved. After a period of time, manual replenishment is also required. This reliance on manual labor is not only prone to errors but also consumes significant human resources. By using a transport vehicle 2, magnetic strips 3 are first attached to the bottom of the pharmacy to guide the AGV navigation equipment, allowing the drugs in the categorized storage cabinet 1 to be placed into the storage box 5. Different types of medicines are stored in the sorting cabinet 1. Driven by the drive wheels and AGV navigation equipment, the sorting cabinet 1 is moved to a designated location in the pharmacy. The temperature and humidity at this location should be suitable for storing the medicines. When retrieving medicines, the corresponding scissor-drive module 7 is activated to push the medicines out of the sorting box 5. Before pushing, the transport vehicle 2, guided by the AGV navigation equipment and electric wheels, moves below the sorting box 5, allowing the medicines to fall into the recessed groove 14. After all medicines have been retrieved, the transport vehicle 2 moves to the retrieval port for manual verification. Once verified, the medicines can be taken out. When medicines need to be replenished, a batch of neatly arranged medicines is placed on the medicine dispensing assembly, and the transport vehicle 2 is moved to the corresponding arrangement box 5. The medicine dispensing assembly then places the medicines into the arrangement box 5. This setup achieves the effects of mechanical medicine retrieval, storage, and directional movement of the classified storage cabinet 1, greatly reducing manual labor. At the same time, the purely mechanical operation and final manual verification also reduce the occurrence of errors. The scissor drive module 7 includes two folding frames and an electric pull rod. By pulling the bottom of the folding frame to make it close together, the folding frame unfolds and becomes longer, thereby completing the ejection operation.

[0032] A scissor-drive module 20 is fixedly installed on the inner bottom surface of the recessed groove 14. A tray 19 is fixedly installed on the top of the scissor-drive module 20. One side of the tray 19 is open. A servo motor is fixedly installed on one side of the tray 19. A baffle 28 is fixedly installed at the output end of the servo motor. Multiple scissor-drive modules 21 are fixedly installed on the side of the tray 19 away from the baffle 28. During operation, the missing medicines are neatly arranged on the tray 19. The scissor-drive module 21 is activated to push the medicines against the baffle 28, reducing the shaking of the medicines during movement. When the medicines are moved to the outside of the corresponding arrangement box 5, the scissor-drive module 20 is activated to raise the tray 19 to the corresponding height. Then, the servo motor is activated to raise the baffle 28, allowing the medicines to be neatly pressed into the arrangement box 5 under the push of the scissor-drive module 21, thus achieving stable medicine replenishment.

[0033] A fixing frame 12 is fixedly installed at the front end of the arrangement box 5. An outer sleeve 10 is rotatably connected to the outside of the fixing frame 12. A blocking plate 9 is fixedly installed on the outside of the outer sleeve 10. The blocking plate 9 is made of elastic material. Multiple detection strips 13 are fixedly installed on the outside of the blocking plate 9. A detection positioning module 8 is fixedly installed at the bottom end of the arrangement box 5. During operation, in conjunction with the setting of the blocking plate 9, the end of the arrangement box 5 can be sealed, so that the medicine is subject to a certain resistance when it is discharged. When one medicine is pushed out, the next medicine will be pressed down by the elastic blocking plate 9, reducing the problem of multiple medicines being squeezed out. The detection and positioning module 8 and the detection strip 13 are designed such that whenever a medicine is pushed out, the blocking plate 9 and the detection strip 13 move away from the detection and positioning module 8. When the medicine is completely pushed out, the blocking plate 9 will return under its own elasticity, and the detection strip 13 will come into contact with the detection and positioning module 8 again. At this time, the detection and positioning module 8 will count and transmit the count information outward, so as to accurately determine the number of medicines released and know the remaining space in the arrangement box 5. At the same time, the detection and positioning module 8 also has a positioning signal sending function to guide the tray 19 to rise to a specified height to ensure the accuracy of filling medicines.

[0034] Two rows of sliding grooves 23 are provided on the inner wall of the bottom surface of the tray 19. Two symmetrically arranged center plates 26 are slidably connected to the top surface of the sliding grooves 23. A power component is fixedly connected between the center plates 26 and the tray 19. The power component is used to push the center plates 26 to slide. During operation, in order to ensure that the medicine is aligned with the arrangement box 5 when the medicine is placed in the tray 19, the power component is activated to drive the two center plates 26 to squeeze towards the center. With the compression of the scissor drive module 21, the baffle 28 and the two center plates 26, the medicine is squeezed from four directions, which further reduces the problem of medicine displacement and filling errors when the transport vehicle 2 moves.

[0035] The power assembly includes an elastic bladder 27, which is fixedly connected between the center plate 26 and the inner wall of the tray 19. Two sets of air pressure assemblies are fixedly installed in the inner wall of the tray 19, arranged symmetrically. Each air pressure assembly includes a negative pressure unit 24 and a blower 25, both of which are connected to the inner side of the elastic bladder 27. Two sets of springs are fixedly connected between the center plate 26 and the tray 19, located inside the elastic bladder 27. During operation, when medicines are placed into the tray 19, the blower 25 is activated to pump air into the elastic bladder 27. Air is forced into the center plate 26, causing the elastic bladder 27 to expand laterally. This pushes the center plate 26 to move. After the compression ends, the negative pressure machine 24 is activated to extract the air. Combined with the compression of the spring, the center plate 26 returns to its original position. This design allows the center plate 26 to occupy less space after retraction. Compared with structures such as electric telescopic rods, it can reserve more space for the tray 19 to place medicines. The thrust of the scissor drive module 21 is relatively small. It can push the medicines but will not crush the elastic bladder 27. In addition, the two sliding grooves 23 ensure that the center plate 26 moves stably.

[0036] The outer sleeve 10 has a through groove extending to the inner cavity at its outer center. A stop bar 11 is fixedly installed on the outer side of the fixing frame 12. The stop bar 11 passes through the through groove and is slidably connected to it. During operation, with the through groove and the stop bar 11 in place, when the medicine is extruded into the arrangement box 5, the outer sleeve 10 is blocked by the stop bar 11 and cannot rotate outward. This allows the elastic potential energy of the blocking plate 9 to be fully applied to the medicine, reducing the problem of excess medicine falling off. When the medicine is replenished, the outer sleeve 10 can rotate counterclockwise, and the stop bar 11 will not block the outer sleeve 10, so the blocking plate 9 will not deform. After the medicine is applied, the blocking plate 9 will return to its original position under the action of gravity. This design reduces the deformation frequency of the blocking plate 9 and increases its service life.

[0037] Multiple transmission rods 6 are rotatably connected to the inner side of the storage slot 4. A drive motor is fixedly installed at the end of each transmission rod 6. The drive motor is fixedly connected to the classification storage cabinet 1. The outer side of each transmission rod 6 is fixedly connected to the bottom surface of the arrangement box 5. During operation, when replenishing medicines, the drive motor is started to drive the transmission rods 6 and the arrangement box 5 to rotate to a horizontal state. After replenishment is completed, the drive motor is turned off. Under the action of gravity, the end of the arrangement box 5 sinks, causing the arrangement box 5 to tilt, allowing the medicines to slide down to the end of the scissor-type drive module 7 under the action of gravity. This setting allows the medicines to be arranged more neatly and can assist in the medicine ejection process.

[0038] Multiple unit slots 29 are formed on the inner wall of the storage slot 4. The unit slots 29 are vertical and are correspondingly arranged with multiple arrangement boxes 5. A straight rod is fixedly installed at the end of the arrangement box 5 away from the blocking plate 9. The straight rod is slidably connected to the unit slot 29. During operation, the arrangement of the unit slots 29 and the straight rod allows the end of the arrangement box 5 to have a force point after tilting, ensuring the stability of the arrangement box 5. After the medicine is applied, the drive motor can be started multiple times to make the arrangement box 5 repeatedly tilt and swing, thereby generating vibration. Under the action of vibration and gravity, the medicine is arranged neatly, effectively assisting in the medicine ejection process.

[0039] The inner wall of the recessed groove 14 has an annular groove near its top surface. A sliding rod 17 is slidably connected to the inner side of the annular groove. A blocking curtain 18 is fixedly connected between the sliding rod 17 and the inner wall of the recessed groove 14. A power assembly is provided on the outer side of the sliding rod 17. The power assembly is used to drive the sliding rod 17 to slide. The blocking curtain 18 is made of flexible material. During operation, when receiving the ejected medicine, the power assembly is activated to drive the sliding rod 17 to slide from the annular groove, allowing the flexible blocking curtain 18 to block the opening of the recessed groove 14. This allows the falling medicine to be caught by the flexible blocking curtain 18, reducing damage to the medicine. Furthermore, the flexible blocking curtain 18 is not elastic and will not rebound, causing the medicine to fly out.

[0040] Example 2

[0041] like Figure 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: The power assembly includes two symmetrically arranged drive boxes 15. The drive boxes 15 are fixedly connected to the outer wall of the transport vehicle 2. A motor is fixedly installed on the inner side of the drive box 15. A connecting rope 16 is wound around the output end of the motor. The two ends of the connecting rope 16 pass through the annular groove and are fixedly connected to the two ends of the slide rod 17. A magnet is fixedly installed in the middle of the blocking curtain 18. The transport vehicle 2 is made of magnetic metal material. When it needs to be unfolded during operation, one of the motors is started to wind the connecting rope 16, thereby pulling the slide rod 17 so that the blocking curtain 18 seals the recessed groove 14. When the medicine is removed, the other motor is started to roll up the other connecting rope 16, which can pull the slide rod 17 to move in the opposite direction and fold the blocking curtain 18. With the setting of the magnet, the folded blocking curtain 18 can be attached to the inner wall of the transport vehicle 2 under the magnetic adsorption.

[0042] During operation, the hospital pharmacy has a large quantity of medicines. To ensure convenient access, medicines need to be categorized and placed on designated shelves. Medications are then retrieved manually, and replenishment is required periodically. This reliance on manual labor is prone to errors and consumes significant manpower. By using a transport vehicle 2, magnetic strips 3 are attached to the floor of the pharmacy to guide the AGV navigation equipment. Based on the different types of medicines in the categorized storage cabinet 1, the drive wheels of the cabinet 1 and the AGV navigation equipment move the cabinet 1 to a designated location within the pharmacy. The temperature and humidity at this location should be suitable for the storage of the medicines. When retrieving a medicine, the corresponding scissor-drive module 7 is activated. The medicines in the arrangement box 5 are pushed outwards. Before pushing, the transport vehicle 2, guided by the AGV navigation equipment and electric wheels, moves to the bottom of the arrangement box 5, allowing the medicines to fall into the recessed groove 14. After all the medicines are retrieved, the transport vehicle 2 moves to the medicine retrieval port for manual verification. Once verified, the medicines can be retrieved. When medicines need to be replenished, a batch of neatly arranged medicines is placed on the medicine dispensing component, and the transport vehicle 2 moves to the corresponding arrangement box 5, allowing the medicine dispensing component to place the medicines into the arrangement box 5. This setup achieves the effects of mechanical medicine retrieval, storage, and directional movement of the classified storage cabinet 1, greatly reducing manual labor. At the same time, the purely mechanical operation and final manual verification also reduce the occurrence of errors. The scissor drive module 7 includes a folding mechanism. Two folding frames and an electric pull rod are used to merge the folding frames by pulling their bottom ends, thus unfolding and lengthening them to complete the ejection operation. The missing medicines are neatly arranged on tray 19. The scissor-drive module 21 is activated to push the medicines against the baffle 28, reducing medicine swaying during movement. Once the medicines are moved to the outside of the corresponding arrangement box 5, the scissor-drive module 20 is activated to raise tray 19 to the corresponding height. Then, the servo motor is activated to raise the baffle 28, allowing the medicines to be neatly pressed into the arrangement box 5 under the push of the scissor-drive module 21, thus achieving stable medicine replenishment. With the addition of the blocking plate 9, the end of the arrangement box 5 can be sealed, providing resistance to the medicines during discharge. When one medicine is pushed out, the next medicine is held down by the elastic blocking plate 9, reducing the problem of multiple medicines being squeezed out. The detection positioning module 8 and the detection strip 13 are set so that whenever a medicine is pushed out, the blocking plate 9 and the detection strip 13 will move away from the detection positioning module 8. When the medicine is completely pushed out, the blocking plate 9 will return under its own elasticity, and the detection strip 13 will come into contact with the detection positioning module 8 again. At this time, the detection positioning module 8 will count and transmit the count information outward, so as to accurately determine the number of medicines discharged and know the remaining space in the arrangement box 5. At the same time, the detection positioning module 8 also has a positioning signal sending function to guide the tray 19 to rise to a specified height to ensure the accuracy of filling medicines.To ensure the medicine is aligned with the arrangement box 5 during loading, when the medicine is placed in the tray 19, the power unit is activated to drive the two center plates 26 to press towards the center. This, combined with the compression from the scissor-drive module 21, the baffle 28, and the two center plates 26, compresses the medicine from four directions, further reducing the problem of medicine displacement leading to incorrect filling during transport vehicle 2 movement. When the medicine is neatly arranged in the tray 19, the blower 25 is activated to press air into the elastic bladder 27, causing the elastic bladder 27 to expand laterally, thereby pushing the center plates 26 to move. After compression, the negative pressure machine 24 is activated to extract the air, and with the compression of the spring, the center plates 26 return to their original position. This design minimizes the space occupied by the retracted center plate 26, allowing for a larger space on the tray 19 for medicines compared to structures like electric telescopic rods. The scissor-drive module 21 has a smaller thrust, capable of pushing medicines without damaging the elastic bladder 27. Combined with the two sliding grooves 23, this ensures stable movement of the center plate 26. Furthermore, the through groove and stop bar 11 prevent the outer tube 10 from rotating outwards when medicines are extruded from the arrangement box 5. This ensures that the elastic potential energy of the blocking plate 9 is fully applied to the medicines, reducing excess medicine falling out. When medicines are replenished, the outer tube 10 can rotate counter-clockwise. Rotation ensures that the stop lever 11 does not obstruct the outer sleeve 10, and the blocking plate 9 does not deform. After medication application, the blocking plate 9 returns to its original position under gravity. This design reduces the deformation frequency of the blocking plate 9 and increases its service life. When replenishing medication, the drive motor is activated to rotate the transmission rod 6 and the arrangement box 5 to a horizontal position. After replenishment, the drive motor is turned off, and the end of the arrangement box 5 sinks under gravity, causing it to tilt and allowing the medication to slide down to the end of the scissor-type drive module 7. This design allows for more neat arrangement of medication and assists in the medication ejection process. This works in conjunction with the unit slot 29 and... The straight rod design ensures that the end of the arrangement box 5 has a force point after tilting, guaranteeing its stability. After medication is applied, the drive motor can be repeatedly activated to cause the arrangement box 5 to repeatedly swing upwards, generating vibration. Under the combined effect of vibration and gravity, the medication is neatly arranged, effectively assisting in the medication ejection process. When receiving ejected medication, the power assembly is activated, causing the slide rod 17 to slide from the annular groove. This allows the flexible blocking curtain 18 to block the falling medication at the opening of the recessed groove 14, catching it and reducing damage. Furthermore, the flexible blocking curtain 18 is non-elastic, preventing rebound and medication from flying out.
