[0024] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0025] like Figures 1-3 As shown in the illustration, this utility model provides a lifting platform 300 suitable for vending machine 100, including: a panel 10 and a tray 20, the panel 10 and the tray 20 forming a cavity 30 for accommodating goods released by the vending machine 100, and the panel 10 having a dispensing port 11; it also includes: a driving mechanism 40, connected to the tray 20, for driving the tray 20 to move vertically; wherein, the initial position of the tray 20 is lower than the dispensing port 11, and the tray 20 can move from the initial position to a first preset position under the drive of the driving mechanism 40, so as to release the goods in the cavity 30 outward through the dispensing port 11. In this utility model embodiment, the goods sold by the vending machine 100 are all described using 550ml bottled beverages as an example.

[0026] In this embodiment, the panel 10 has a square structure and includes a front side and a rear side. In practical applications, the vending machine 100 is located behind the panel 10, with the side of the panel 10 furthest from the vending machine 100 being the front side and the side closer to the vending machine 100 being the rear side. The tray 20 is located on the rear side of the panel 10, specifically in the space between the vending machine 100 and the panel 10, and is used to catch beverages that fall from the vending machine 100.

[0027] Panel 10 and tray 20 together form a cavity 30 for receiving beverages dropped from vending machine 100, with panel 10 serving as the front baffle of cavity 30. The cavity 30 initially formed by panel 10 and tray 20 has a suitable depth to accommodate beverages of common sizes found in vending machine 100. A dispensing port 11 is provided at the top of panel 10, which serves as a channel for dispensing (removing) beverages from tray 20.

[0028] The tray 20 is connected to a drive mechanism 40 for driving its up and down movement. The drive mechanism 40 can control the vertical position of the tray 20, thereby accurately moving the beverage on the tray 20 upward to a first preset position. When the tray 20 is in the first preset position, the beverage on the tray 20 can fall outward through the delivery port 11, specifically into the receiving port 210 of the delivery robot 200.

[0029] In this embodiment, when the tray 20 is at a lower position relative to the panel 10, the panel 10 and the tray 20 form a cavity 30. As the tray 20 rises to a certain height, the cavity 30 gradually decreases until the beverage can be retrieved through the dispensing port 11. Specifically, in robot retrieval mode, the tray 20 rises to a higher position (first preset position) so that the beverage is released through the dispensing port 11 to the receiving port 210 of the delivery robot 200; in manual retrieval mode, the tray 20 rises to a lower position (second preset position), allowing the user to directly retrieve the beverage through the dispensing port 11 without having to bend over or squat down significantly. Here, the higher position is higher than the lower position.

[0030] In one specific embodiment, when the pallet 20 rises to the first preset position, the bottom end of the support portion 22 of the pallet 20 remains at the same level as the outlet 11.

[0031] In this embodiment, the initial position of the tray 20 refers to its lowest working position. This position needs to meet the following requirements: it must be able to receive the beverage 21 released by the vending machine 100. Specifically, the tray 20 is located below the dispensing port 110 of the vending machine 100, ensuring that the beverage 21 falls into the cavity 30 formed by the tray 20 and the panel 10. This position serves as the starting reference position for the movement of the tray 20. From this initial position, the tray 20 will rise to: a first preset position (a higher position for robot pickup); and a second preset position (a lower position for manual pickup).

[0032] In one specific embodiment, the initial position of the tray 20 should be: below the dispensing port 11 at the top of the panel 10; below the bottom of the guide plate 50; and located in the middle region of the panel 10. This initial position setting ensures that the beverage 21 can reliably fall from the vending machine 100 into the lifting platform 300, and provides a good starting point for subsequent lifting operations.

[0033] like Figure 2a As shown, in one embodiment, it further includes: guide plates 50 disposed opposite to each other, trays 20 disposed between the guide plates 50, the guide plates 50 being used to guide the beverages released by the vending machine 100 to the trays 20.

[0034] In this embodiment, the two guide plates 50 are symmetrically distributed from left to right, and the tray 20 is disposed between the two guide plates 50. The main function of the guide plates 50 is to accurately guide the beverages dropped from the vending machine 100 onto the tray 20, preventing the beverages from deviating before falling into the cavity 30 formed by the tray 20 and the panel 10.

[0035] Specifically, the guide plate 50 is inclined to ensure that the beverage slides down smoothly. The position of the guide plate 50 corresponds to the dispensing port 110 of the vending machine 100, with one guide plate 50 corresponding to one dispensing port 110. When the vending machine 100 drops a beverage, the beverage will slide naturally along the inclined guide plate 50 onto the tray 20.

[0036] By setting up such a guide plate 50, there is no need to modify the existing vending machine 100. After the vending machine 100 dispenses the beverage, it can fall directly onto the tray 20 with the help of the guide plate 50, so that the tray 20 can lift the beverage to the (first or second) preset position.

[0037] like Figure 2a As shown, in one embodiment, a baffle 60 is provided between the guide plate 50 and the panel 10 to prevent beverages released by the vending machine 100 from falling into the gap between the guide plate 50 and the panel 10.

[0038] In this embodiment, the baffle 60 effectively prevents beverages dispensed from the vending machine 100 from falling into the gap between the guide plate 50 and the panel 10. Specifically, the height of the baffle 60 is higher than the height of the dispensing port 110 of the vending machine 100, thus ensuring that beverages of any size can be blocked.

[0039] When the vending machine 100 dispenses a beverage, the beverage first comes into contact with the baffle 60. Due to the presence of the baffle 60, the beverage is guided to the surface of the guide plate 50, preventing it from falling into the gap between the guide plate 50 and the panel 10. This design avoids the risk of beverage getting stuck.

[0040] The combination of baffle 60, guide plate 50 and panel 10 forms a closed guide channel, which can ensure that the beverage can be reliably guided to tray 20 after being released from vending machine 100, and prevent the beverage from falling into the gap and getting stuck.

[0041] like Figure 1 and Figure 2a As shown, in one embodiment, the drive mechanism 40 includes a control unit 41 and a drive unit 42, with the drive unit 42 connected to the pallet 20. The drive unit 42 is used to drive the pallet 20 from an initial position to a first preset position or a second preset position under the control of the control unit 41. The first preset position corresponds to the robot picking position, and the second preset position corresponds to the manual picking position. The first preset position is higher than the second preset position.

[0042] In this embodiment, the drive mechanism 40 adopts a chain drive mechanism (such as a chain window opener), with its own control system and transmission mechanism serving as the control unit 41 and drive unit 42, respectively. Specifically, the control system includes a drive motor and its controller (not shown in the figures); the transmission mechanism includes a reducer, a gear set, a chain, and a sprocket (not shown in the figures). The drive motor serves as a power source, and the reducer and gear set convert the high-speed, low-torque output of the drive motor into a low-speed, high-torque output, ensuring smooth movement of the pallet 20; the chain is fixedly connected to the pallet 20, and the chain and sprocket convert the rotational motion of the drive motor into the linear motion of the pallet 20.

[0043] In actual operation, when a beverage is detected falling onto the tray 20, the controller sends a corresponding control command to the drive motor according to the current working mode (manual retrieval mode or robot retrieval mode). Upon receiving the command, the drive motor starts running, transmitting power to the transmission mechanism (chain and sprocket, etc.). The chain engages with the sprocket, pushing the tray 20 upward until it reaches the first preset position or the second preset position.

[0044] In this embodiment, different retrieval modes correspond to different height positions. Specifically, when a user operates the control panel of the vending machine 100, it indicates that the user wants to retrieve the goods themselves; this is the manual retrieval mode, and the tray 20 will move from the initial position to the second preset position (lower position). When a user places an order remotely, it indicates that the user needs to use a robot to retrieve the goods; this is the robot retrieval mode, and the tray 20 will move from the initial position to the first preset position (higher position) so that the beverage can fall directly into the receiving port 210 of the delivery robot 200.

[0045] In other embodiments, the drive mechanism 40 employs a ball screw assembly, which includes components such as a drive motor, a lead screw, and a nut seat (not shown in the figures). The drive motor is connected to the lead screw via a coupling, and the nut seat on the lead screw is fixedly connected to the support plate 20, used to drive the support plate 20 to move upward or downward.

[0046] like Figure 2b and Figure 2c As shown, in another embodiment, the drive mechanism 40 employs a synchronous belt drive, including a drive motor 43, a synchronous belt pulley assembly 44, and a synchronous belt 45. The synchronous belt pulley assembly 44 includes a driving pulley and a driven pulley. The driving pulley is fixedly connected to the output shaft of the drive motor 43, and the driven pulley is mounted opposite the driving pulley. The synchronous belt 45 wraps around the driving pulley and the driven pulley, and one side of the synchronous belt 45 is fixedly connected to the support plate 20. The drive motor 43 serves as a power source, converting its rotational motion into linear motion of the support plate 20 via the synchronous belt pulley assembly 44.

[0047] In actual operation, when the control unit 41 receives a signal that there is a beverage 21 on the tray 20, it sends a control command to the drive motor 43 according to the current working mode. After the drive motor 43 starts, it drives the drive wheel to rotate, and transmits power to the tray 20 through the synchronous belt 45, so that the tray 20 reaches the target position. After the beverage 21 is removed, the drive motor 43 is started again, and the tray 20 is brought back to the initial position through the synchronous belt 45.

[0048] like Figure 2a As shown, in one embodiment, a photoelectric detection component is provided in the tray 20 to detect whether there is a beverage in the cavity 30 and send a detection signal to the control unit 41. The control unit 41 controls the operation of the drive unit 42 according to the detection signal.

[0049] In this embodiment, the photoelectric detection component is a through-beam sensor, including a transmitter 71 and a receiver 72. The through-beam sensor is disposed at both ends of the tray 20, and the light beam emitted by the transmitter 71 is received by the receiver 72. Specifically, the transmitter 71 and the receiver 72 are respectively fixed to the inner walls of both sides of the tray 20, and the transmitter 71 and the receiver 72 are installed at the same height to form a horizontal detection light path.

[0050] When a beverage falls onto the tray 20, it blocks the transmission of the light beam, thus being detected by the photoelectric detection component. During operation, when the vending machine 100 releases a beverage and it falls onto the tray 20, the beverage blocks the light beam, and the photoelectric detection component transmits a detection signal to the control unit 41. Upon receiving the signal, the control unit 41 controls the drive unit 42 to move the tray 20 upwards to a (first or second) preset position.

[0051] Once the beverage leaves the tray 20 (either being picked up or transferred to the receiving port 210 of the delivery robot 200), the light beam is received again by the receiver 72. The photoelectric detection component detects that there is no beverage in the tray 20 and sends a signal to the control unit 41 again. The control unit 41 then controls the drive unit 42 to lower and reset the tray 20. This design ensures that the tray 20 can respond promptly to the presence of beverages, achieving automated control.

[0052] This automatic control scheme based on photoelectric detection can accurately sense the status of beverages in the tray 20 and respond accordingly in a timely manner, greatly improving the level of automation and picking efficiency.

[0053] like Figure 2a As shown, in one embodiment, it further includes: a first position sensor 81 and a second position sensor 82 arranged vertically at intervals. The first position sensor 81 is used to detect whether the tray 20 has reached a first preset position, and the second position sensor 82 is used to detect whether the tray 20 has reached a second preset position. The first position sensor 81 and the second position sensor 82 are electrically connected to the control unit 41.

[0054] In this embodiment, a first position sensor 81 and a second position sensor 82, spaced vertically apart, are disposed near the outlet 11 of the panel 10. These two position sensors are used to detect the relative position between the pallet 20 and the outlet 11, wherein the first position sensor 81 corresponds to the robot's picking position and the second position sensor 82 corresponds to the manual picking position.

[0055] Specifically, both the first position sensor 81 and the second position sensor 82 are KI1249 type photoelectric switches, employing diffuse reflection detection to achieve target detection through the reflection of light by the object's surface. The first position sensor 81 is installed at a higher position, corresponding to the robot's picking position. When the pallet 20 rises to this position, the infrared beam emitted by the emitting part of the KI1249 type photoelectric switch is reflected by the pallet 20. The receiving part detects the change in the intensity of the reflected signal and generates a switching output, notifying the control unit 41 that the pallet 20 has reached the first preset position. Similarly, the second position sensor 82 is installed at a lower position, corresponding to the manual picking position. When the pallet 20 moves to this position, it triggers a signal output through the same working principle.

[0056] In actual operation, after the vending machine 100 determines the retrieval method according to the user's operation mode, the tray 20 will move to the corresponding preset position. The KI1249 photoelectric switch accurately detects and sends a position signal to ensure that the stop position of the tray 20 can be controlled. Whether it is manual retrieval or robot retrieval, convenient beverage retrieval can be achieved.

[0057] In other embodiments, the first position sensor 81 and the second position sensor 82 may be contact sensors, such as microswitches.

[0058] like Figure 4 As shown, in one embodiment, the tray 20 includes a support portion 22, which is inclined so that when the tray 20 reaches the first preset position, the beverage in the cavity 30 can slide along the support portion 22 towards the outlet 11 under the action of gravity.

[0059] In this embodiment, the tray 20 includes a support portion 22 and limiting portions 23 disposed at the left and right ends of the support portion 22. The support portion 22 is designed at an angle and is mainly used to receive beverages released by the vending machine 100. The limiting portions 23 are provided to prevent beverages from falling from the left or right end of the support portion 22 during upward movement.

[0060] Specifically, the support part 22 is inclined at 15 degrees relative to the horizontal plane, with the inclination direction facing the outlet 11. This inclination angle ensures that the beverage slides reliably under the action of gravity without causing the sliding speed to be too fast.

[0061] The limiting part 23 is set perpendicular to the support part 22, and its height is greater than the diameter of the beverage to ensure that the beverage will not fall from the left and right ends of the tray 20.

[0062] When the pallet 20 rises to the first preset position, due to the inclined design of the support part 22 of the pallet 20, the beverage in the cavity 30 will naturally slide towards the delivery port 11 under the action of gravity. That is, at this time, no additional power device is needed to push the beverage; the beverage can be transferred to the delivery robot 200 by gravity alone. This design simplifies the structure and improves the reliability of the transfer.

[0063] In one specific embodiment, the transmitting end 71 of the photoelectric detection component is mounted on the limiting part 23 at the left end, and the receiving end 72 is mounted on the limiting part 23 at the right end.

[0064] like Figure 1 As shown, in one embodiment, a guide assembly is provided between the panel 10 and the tray 20. The guide assembly includes a vertical slide rail 91 mounted on the panel 10 and a slider 92 mounted on the tray 20. The slider 92 is slidably engaged with the vertical slide rail 91.

[0065] In this embodiment, the vertical slide rail 91 is fixed to the rear side of the panel 10 and is vertically arranged to ensure that the lifting and lowering movement of the tray 20 is carried out in a strictly vertical direction. The slider 92 is fixed on the tray 20 and cooperates with the vertical slide rail 91 to form a sliding pair. Specifically, each tray 20 has a slider 92 installed on each side, corresponding one-to-one with the two vertical slide rails 91 on the rear side of the panel 10.

[0066] This design, with the sliding rail 91 and slider 92 working together, ensures that the pallet 20 moves along a predetermined path during lifting, preventing it from swaying or shifting. Simultaneously, the guide assembly enhances the stability and reliability of the entire lifting mechanism.

[0067] like Figures 5-7 As shown, corresponding to the above lifting platform 300, this utility model embodiment also provides a vending device, including: an automatic vending machine 100 and the lifting platform 300 of any of the aforementioned embodiments.

[0068] In this embodiment, the use of the lifting platform 300 does not require any modification to the structure of the vending machine 100 itself, and can be directly installed on the front side of the existing vending machine 100. This design solution can achieve the function of automatic beverage delivery without increasing the modification cost of the vending machine 100.

[0069] In practical applications, the guide plate 50 of the lifting platform 300 corresponds to the dispensing port 110 of the vending machine 100. When the vending machine 100 dispenses a beverage, the beverage slides down the guide plate 50 onto the tray 20. Under the action of the drive mechanism 40, the tray 20 can transport the beverage to different retrieval positions according to actual needs, which is convenient for users to retrieve the beverage manually and also supports automatic retrieval by the delivery robot 200.

[0070] This combined design not only retains the original functions of the vending machine 100, but also expands its application scenarios, enabling it to adapt to the development needs of intelligence and automation.

[0071] like Figure 5 and Figure 6 As shown, in one embodiment, it further includes: a delivery robot 200, a lifting platform 300 disposed between the vending machine 100 and the delivery robot 200, and the receiving port 210 of the delivery robot 200 docking with the discharging port 11 of the lifting platform 300.

[0072] In this embodiment, the lifting platform 300 is installed between the vending machine 100 and the delivery robot 200. The delivery robot 200 is parked in front of the lifting platform 300, and the height of its receiving port 210 matches the height of the dispensing port 11 of the lifting platform 300.

[0073] Specifically, in robot pickup mode, when a user places an order remotely, the vending machine 100 releases a beverage, which is guided by the guide plate 50 and falls onto the tray 20. The tray 20 rises to a first preset position under the action of the drive mechanism 40. Due to the inclined design of the support part 22 of the tray 20, the beverage automatically slides towards the dispensing port 11 and smoothly enters the receiving port 210 of the delivery robot 200. This automated delivery method completes the transfer of beverages without human intervention.

[0074] Through this modular design, the entire vending machine can both meet the convenient pickup needs of users when purchasing on-site and enable automated delivery for remote purchases in conjunction with the delivery robot 200. The drive mechanism 40 automatically determines the current working mode based on the user's operation and controls the tray 20 to move to the corresponding pickup position, achieving intelligent operation with two functions in one machine.

[0075] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
