[0011] Preferably, the control module further includes a first infrared sensor, a first micro switch, and a second micro switch. The first infrared sensor is located on the frame, and the first and second micro switches are located on the material handling rack. The first infrared sensor, the first micro switch, and the second micro switch are all signal-connected to the motor controller, and the motor controller sends control signals to the second motor.

[0012] Preferably, the control module further includes a second infrared sensor located on the guide plate.

[0016] The beneficial effects proposed by this utility model are as follows:

[0017] Goods are placed on the shelf. The person picking up the goods sends a signal to the pusher assembly through the control module. The first channel is located in the upper area of ​​the rack, the second channel is located in the lower area of ​​the rack, and the picking rack is located between the first channel and the second channel. The picking rack is set in the middle area of ​​the rack so that the person picking up the goods does not need to bend over to the bottom of the rack to pick up the goods, which makes it convenient for people with difficulty bending over to pick up and put down the goods. Taking the first channel as an example, after the pushing component pushes the goods stored on the shelf out, they fall onto the guide plate through the first channel. The goods move along the guide plate to the picking rack. When the goods come into contact with the guide plate, a signal is generated and sent to the control module. The control module then sends a control signal to the drive component, which drives the sliding door to open, allowing the customer to take the goods placed on the picking rack. Alternatively, when goods are output from the second channel, the lifting component assists in conveying the goods from the second channel to the picking rack. When the lifting component conveys the goods to the picking rack, it sends a signal to the control module, which then sends a control signal to the drive component. The drive component drives the sliding door to open, allowing the customer to take the goods placed on the picking rack. During the above process, after the customer has finished taking the goods, the control module sends a control signal to the drive component, which then drives the sliding door to close. Automatic opening and closing of the pickup port improves the efficiency of pickup and reduces the risk of hands getting stuck due to the barrier. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figures 1 to 12A smart vending machine includes a frame 1, a shelf 3, a first channel 4, and a second channel 5. The frame 1 is equipped with a cabinet door 2, which is hinged to the frame 1. The shelf 3 is located inside the frame 1 and is equipped with several pushing components. The shelf 3 is connected to the first channel 4 and the second channel 5 respectively. The frame 1 is equipped with a picking rack 6, which is connected to the first channel 4 and the second channel 5 respectively. A guide plate 7 is provided between the picking rack 6 and the first channel 4. A lifting component is provided between the picking rack 6 and the second channel 5. The picking rack 6 is equipped with a sliding door 8, which is equipped with a drive component. The frame 1 is equipped with a control module. The drive component, the lifting component, and the control module are all electrically connected to an external power source. The guide plate 7, the drive component, and the lifting component are all signal connected to the control module. Specifically, the goods are placed on the shelf 3. The person picking up the goods sends a signal to the pushing component through the control module. The first channel 4 is located in the upper area of ​​the frame 1, the second channel 5 is located in the lower area of ​​the frame 1, and the picking rack 6 is located between the first channel 4 and the second channel 5. The picking rack 6 is set in the middle area of ​​the frame 1 so that the person picking up the goods does not need to bend over to the bottom of the frame 1 to pick up the goods, which makes it convenient for people with difficulty bending over to pick up and put down the goods. Taking the first channel 4 as an example, after the pushing component pushes the goods stored on the shelf 3, they fall onto the guide plate 7 through the first channel 4. The goods move along the guide plate 7 to the picking rack 6. When the goods come into contact with the guide plate 7, a signal is generated and sent to the control module. The control module then sends a control signal to the drive component, which drives the sliding door 8 to open, allowing the customer to take the goods placed on the picking rack 6. Alternatively, when goods are output from the second channel 5, the lifting component assists in conveying the goods from the second channel 5 to the picking rack 6. When the lifting component conveys the goods to the picking rack 6, it sends a signal to the control module, which then sends a control signal to the drive component. The drive component drives the sliding door 8 to open, allowing the customer to take the goods placed on the picking rack 6. In the above process, after the customer has finished taking the goods, the control module sends a control signal to the drive component, which then drives the sliding door 8 to close. Automatic opening and closing of the pickup port improves the efficiency of pickup and reduces the risk of hands getting stuck due to the baffle.

[0033] Specifically, the feeding assembly includes a first motor 9 and a screw rod 10. The first motors 9 are evenly distributed on the shelf 3, and their output shafts are fixedly connected to the screw rods 10. The first motors 9 are electrically connected to an external power source and signal-connected to the control module. When the first motor 9 receives a control signal from the control module, its output shaft rotates, and the screw rod 10 rotates synchronously. At this time, the goods are placed on the screw rod 10. The screw rod 10, through rotation, drives the goods to move on the shelf 3 until they are conveyed to the first channel 4 or the second channel 5. By using the screw rod 10 to store and convey goods on the shelf 3, the gaps in the screw pitch of the screw rod 10 can be used to clamp the goods, improving the stability of goods storage and movement. At the same time, the goods can be spaced out using the gaps in the screw pitch of the screw rod 10, which can also improve the accuracy of goods output and reduce the occurrence of discrepancies between the output quantity and the specified quantity.

[0034] Specifically, the drive assembly includes a second motor 11, a first synchronous pulley 12, and a second synchronous pulley 13. The second motor 11 is located inside the frame 1, and the output shaft of the second motor 11 is fixedly connected to the first synchronous pulley 12. The frame 1 is provided with a first rotating shaft 14, which is fixedly connected to the second synchronous pulley 13. A first synchronous belt 15 is provided between the first synchronous pulley 12 and the second synchronous pulley 13. The first synchronous belt 15 is provided with a plurality of connecting blocks 16, which are fixedly connected to the sliding door 8. The material handling rack 6 is provided with a sliding groove 33, and the sliding door 8 slides relative to the sliding groove 33. The second motor 11 is electrically connected to an external power source and signal-connected to the control module. After receiving the control signal from the control module, the output shaft of the second motor 11 rotates, driving the first synchronous pulley 12 to rotate. Through the connection of the first synchronous belt 15, the second synchronous pulley 13 rotates synchronously. There are at least two connecting blocks 16, which are installed vertically on the first synchronous belt 15. When the first synchronous belt 15 moves with the rotation of the output shaft of the second motor 11, the connecting blocks 16 move in opposite directions. Because the sliding door 8 slides relative to the slide groove 33, the sliding door 8 is opened or closed, realizing the automatic opening and closing of the picking port.

[0035] Specifically, the lifting assembly includes a third motor 17, a third synchronous pulley 18, and a fourth synchronous pulley 19. The output shaft of the third motor 17 is fixedly connected to the third synchronous pulley 18. The third motor 17 is located inside the frame 1. A second rotating shaft 20 is provided inside the frame 1. The second rotating shaft 20 is fixedly connected to the fourth synchronous pulley 19. A second synchronous belt 21 is provided between the third synchronous pulley 18 and the fourth synchronous pulley 19. A sliding plate 22 is provided on the second synchronous belt 21. The sliding plate 22 is fixedly connected to the second synchronous belt 21. A slide rail 23 is provided between the sliding plate 22 and the frame 1. The slide rail 23 is slidably connected to the sliding plate 22. A slider 24 is provided on the slide rail 23. The slider 24 is slidably connected to the slide rail 23. A baffle 25 is provided on the slider 24. After the pushing component pushes the goods into the second channel 5, the goods fall onto the sliding plate 22. Upon contact with the sliding plate 22, a signal is generated and sent to the control module. The control module then sends a control signal to the third motor 17. The output shaft of the third motor 17 rotates, driving the third synchronous pulley 18 to rotate. Through the connection of the second synchronous belt 21, the fourth synchronous pulley 19 rotates synchronously. At this time, the second synchronous belt 21 moves upward within the second channel 5, driving the sliding plate 22 upward to the material picker 6. The sliding plate 22 is about to reach the material picker 6. When the material is mounted on the pick-up rack 6, the sliding plate 22 will first contact the baffle 25. With the baffle 25 slidably connected to the slide rail 23, the baffle 25 moves upward under the pushing force of the sliding plate 22 until the sliding plate 22 connects with the pick-up rack 6. It should be noted that the size of the baffle 25 is larger than the size of the second channel 5. When the baffle 25 is not under the pushing force of the sliding plate 22, the bottom of the baffle 25 abuts against the pick-up rack 6, and the baffle 25 is limited by the pick-up rack 6, preventing the baffle 25 from moving downward along the slide rail 23 under the action of the slider 24. Simultaneously, when the sliding plate 22 connects with the pick-up rack 6, the baffle 25 triggers the control module to generate a signal. The control module sends a control signal to the second motor 11, causing the output shaft of the second motor 11 to rotate, driving the sliding door 8 to open.

[0036] Specifically, the control module includes a main controller 26 and a motor controller 27. The main controller 26 receives external control signals and is connected to the first motor 9. The motor controller 27 is connected to the second motor 11 and the third motor 17. The recipient can send control signals to the main controller 26, for example, using a mobile terminal (not shown) with control functions. The main controller 26 outputs control signals to the first motor 9, causing the output shaft of the first motor 9 to rotate. The first motor 9 drives the screw rod 10, thereby controlling the output of goods through the pushing assembly.

[0037] Specifically, the control module further includes a first infrared sensor 30, a first micro switch 28, and a second micro switch 29. The first infrared sensor 30 is located on the frame 1, and the first micro switch 28 and the second micro switch 29 are located on the material handling rack 6. The first infrared sensor 30, the first micro switch 28, and the second micro switch 29 are all signal-connected to the motor controller 27, which sends control signals to the second motor 11. When a person reaches into the material handling rack 6 to take goods, the first infrared sensor 30 is triggered when its hand passes through its sensing range. At this time, the first infrared sensor 30 generates a signal and sends it to the motor controller 27. By setting the motor controller 27 to delay for a period of time before sending the control signal to the second motor 11, the second motor 11 drives the sliding door 8 to close. When the sliding door 8 opens until it abuts against the second micro switch 29, it triggers the second micro switch 29 to send a signal to the motor controller 27. The motor controller 27 then sends a control signal to the second motor 11, causing the output shaft of the second motor 11 to stop rotating. When the sliding door 8 closes, it abuts against the first micro switch 28, triggering the first micro switch 28 to send a signal to the motor controller 27. The motor controller 27 then sends a control signal to the second motor 11, causing the output shaft of the second motor 11 to stop rotating. This achieves automatic opening and closing of the sliding door 8. In addition to controlling the second motor 11 to stop rotating, the signal generated by the first micro switch 28 is also sent through the motor controller 27 to the third motor 17, which drives the sliding plate 22 to move downwards to the starting position.

[0038] Specifically, the control module further includes a second infrared sensor 31 located on the guide plate 7. When goods fall onto the guide plate 7 and pass through the sensing range of the second infrared sensor 31, a signal is generated. The second infrared sensor 31 sends the signal to the motor controller 27, which then sends a control signal to the second motor 11. When goods are output from the first channel 4, they come into contact with the guide plate 7 and simultaneously pass through the sensing area of ​​the second infrared sensor 31. The second infrared sensor 31 generates a signal and sends it to the motor controller 27, which then sends a control signal to the second motor 11. The second motor 11 controls the sliding door 8 to open via its output shaft, thus automatically opening the sliding door 8 when goods are output from the first channel 4.

[0039] Specifically, the control module further includes a third infrared sensor 34, a third micro switch 35, and a fourth micro switch 36. The third infrared sensor 34 is located on the sliding plate 22. When goods fall on the sliding plate 22 and pass through the sensing range of the third infrared sensor 34, a signal is generated. The third infrared sensor 34 sends the signal to the motor controller 27, and the motor controller 27 sends a control signal to the third motor 17. The third micro switch 35 is located above the baffle 25, and the fourth micro switch 36 is located below the sliding plate 22. Both the third micro switch 35 and the fourth micro switch 36 are signal-connected to the motor controller 27, and the motor controller 27 sends a control signal to the second motor 11. When goods fall from the shelf 3 onto the sliding plate 22 via the second channel 5, and come into contact with the sliding plate 22, the goods pass through the sensing range of the third infrared sensor 34. The third infrared sensor 34 generates a signal and sends it to the motor controller 27. The motor controller 27 sends a control signal to the third motor 17, causing the output shaft of the third motor 17 to rotate, driving the sliding plate 22 to slide upward until the sliding plate 22 connects with the picking rack 6. When the sliding plate 22 moves upward and abuts against the baffle 25, the sliding plate 22 drives the baffle 25 to move upward. Subsequently, the baffle 25 triggers the third micro switch 35, which generates a signal and sends it to the motor controller 27. The controller 27 sends a control signal to the second motor 11, which controls the opening of the sliding door 8. After the goods are retrieved, the signal generated by the first micro switch 28 not only controls the second motor 11 to stop rotating, but also sends a signal to the third motor 17 through the motor controller 27. The third motor 17 drives the sliding plate 22 to move downward to the starting position. At this time, the sliding plate 22 triggers the fourth micro switch 36. The fourth micro switch 36 generates a signal and sends a control signal to the third motor 17 through the motor controller 27, causing the third motor 17 to stop rotating. This allows the lifting assembly to automatically transport the goods to the picking rack 6 when the goods are output from the second channel 5, and to reset the mechanism after the goods are retrieved.

[0040] Specifically, the guide plate 7 is hinged to the material picker 6, and a torsion spring 32 is provided between the guide plate 7 and the material picker 6. After the guide plate 7 and the material picker 6 are hinged, the guide plate 7 and the material picker 6 form an angle, which facilitates the smooth transport of goods through the guide plate 7 to the sliding door 8, making it convenient for the person picking up the goods. The torsion spring 32 is located at the hinge. The torsion spring 32 contacts the end faces of the guide plate 7 and the material picker 6 respectively. The elastic force generated by the torsion spring 32 causes the guide plate 7 to swing relative to the material picker 6 within a certain angle range. When the goods are output from the first channel 4, they fall freely. When the goods come into contact with the guide plate 7, the elastic force of the torsion spring 32 can buffer the falling goods and reduce the damage to the goods and their packaging boxes caused by falling. At the same time, when the guide plate 7 comes into contact with the goods, it will be flipped downward and compressed by the weight of the goods. Then, the torsion spring 32 will generate a reverse elastic force due to compression to push the guide plate 7 to reset. This reset process flips the guide plate 7 in the opposite direction and pushes the goods out, further improving the efficiency of moving the goods to the sliding door 8.

[0041] Specifically, a lock 37 is provided between the cabinet door 2 and the rack 1. When the goods stored on the rack 3 decrease or are sold out, the supplier opens the cabinet door 2, places the replenishing goods on the rack 3, and then closes the cabinet door 2. The lock 37 is used to lock the rack 1 with the cabinet door 2. The lock 37 can be a mortise lock, or it can be an electric lock, such as the XG07A model. This electric lock is powered on and opened by an external control signal, thereby opening the cabinet door 2. When the cabinet door 2 is closed, the electric lock is in a closed state with the power off, locking the cabinet door 2 to the rack 1.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
