Description

Technical Field

[0001] The present invention relates to the technical field of food delivery devices, and particularly to a food delivery robot. Background Art

[0002] During the meal delivery and distribution process in isolation places (such as isolation hotels or isolation areas in hospitals), it is inevitable for staff to have direct or indirect contact with isolated persons, increasing the risk of infection for the staff. Therefore, it is necessary to use a food delivery robot to deliver or distribute meals in isolation places to reduce the frequency of staff entering the isolation area and lower the risk of cross-infection.

[0003] The food delivery robot includes a vehicle body, a manipulator, and a box body all arranged on the vehicle body. A meal storage area is arranged inside the box body, and multiple meals are stacked in the meal storage area in sequence. The manipulator is used to take out the meals inside the box body and place them on the table in the isolation area. The movement of the vehicle body is controlled by a communication component, enabling the vehicle body to automatically move in each isolation area to deliver meals. However, in the existing food delivery robots, only one layer of meal storage area is arranged inside the box body. Since the meal boxes are disposable foam boxes or disposable plastic boxes, the boxes are prone to soft collapse and deformation under the influence of high temperature for a long time. If a large number of meals are stacked in the same layer of meal storage area, the boxes of the meals at the bottom of the meal storage area are more likely to be crushed, resulting in the overflow of the soup in the meals. If a small number of meals are stacked in the same layer of meal storage area, the meal delivery volume of the food delivery robot is low. Summary of the Invention

[0004] The purpose of the present invention is to provide a food delivery robot with a high meal delivery volume and a low risk of the meal boxes being crushed and deformed.

[0022] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0025] Such as Figure 1 and Figure 2As shown in the figure, the present invention provides a food delivery robot, which includes a vehicle body 1 and a manipulator 2 disposed on the vehicle body 1. The movement of the vehicle body 1 is controlled by an integrated management background, and the integrated management background is communicatively connected to a driving mechanism in the vehicle body through a communication component. The food delivery robot further includes a first box body 3 and a second box body 4 both disposed on the vehicle body 1. The vehicle body 1 is respectively provided with a meal placing end and a meal taking end at intervals in a first direction (i.e., the Y direction in the figure). The first box body 3 is liftably disposed on the meal taking end, and the second box body 4 is disposed close to the meal placing end, and the second box body 4 can move back and forth in the first direction so that the second box body 4 is away from or close to the first box body 3. A first meal storage area is provided inside the first box body 3, and a first conveyor belt 7 for carrying meal boxes 100 is provided at the bottom of the first meal storage area. At least two layers of second meal storage areas are provided inside the second box body 4, and all the second meal storage areas are sequentially spaced apart along the vertical direction. A second conveyor belt 8 is provided at the bottom of each second meal storage area. The second conveyor belt is used to carry the meal boxes 100 inside the second meal storage area and can convey the meal boxes 100 inside the second meal storage area to the first conveyor belt 7 along the first direction. The manipulator 2 is located above the first box body 3 and is used to take out the meal boxes 100 in the first meal storage area.

[0026] The communication component includes a proximal communication module and a distal communication module. The communication module includes 433MHZ or Bluetooth communication for controlling proximal interaction and instruction intertransmission with the automatic doors, elevators and food delivery robots in the hotel; the distal communication module includes wireless communication or 4G / 5G communication for communicating with the integrated management background of the food delivery robot to upload status information, task order information, etc. to the integrated management background for unified management.

[0027] In this embodiment, the first box body 3 and the second box body 4 are provided so that the food delivery robot can transport a larger number of meal boxes 100 at the same time, improving the food delivery volume of the food delivery robot; the second box body 4 that can move in the first direction is provided, and the second conveyor belt 8 on the second box body 4 can batch-convey the meal boxes 100 to the first box body 3 for waiting to be picked up, avoiding a large number of meal boxes 100 from piling up at the meal taking end. Since two layers of second meal storage areas are provided in the second box body 4, and each second meal storage area is carried by the second conveyor belt 8 to hold the meal boxes 100, it prevents the box bodies of the meal boxes 100 from being crushed due to a large number of meal boxes 100 being stacked in the same layer of meal storage area. While improving the food delivery volume of the food delivery robot, the risk of the meal boxes 100 being crushed and deformed is reduced. The liftable first box body 3 is provided, and the height difference between the first conveyor belt 7 and the second conveyor belt 8 can be adjusted by adjusting the height position of the first box body 3, so as to facilitate the transfer of the meal boxes 100 on each layer of the second conveyor belt 8 to the first conveyor belt 7.

[0028] In this embodiment, the first meal storage area can store twelve lunch boxes 100. The length of the second meal storage area in the upper layer of the second box body 4 is greater than that of the second meal storage area in the lower layer. The second meal storage area in the upper layer can store twenty-four lunch boxes 100, and the second meal storage area in the lower layer can store twelve lunch boxes 100.

[0029] Specifically, a first lunch box detector is arranged in the first meal storage area. The first lunch box detector is used to detect whether there is a lunch box 100 in the first meal storage area and whether the lunch box 100 in the first meal storage area is placed in place. A second lunch box detector is arranged in the second meal storage area. The second lunch box detector is used to detect whether there is a lunch box 100 in the second meal storage area and whether the lunch box 100 in the first meal storage area is placed in place.

[0030] In this embodiment, a meal taking position for the manipulator 2 is arranged above the first box body 3, and a lifting platform 5 is arranged at the bottom of the first box body 3. The lifting platform 5 can lift the lunch box 100 in the first meal storage area to the meal taking position. The lifting platform 5 can move along the vertical direction. When the lifting platform 5 moves downward, it drives the first conveyor belt 7 and the lunch box 100 inside the first box body 3 to rise along the vertical direction, so that the topmost lunch box 100 in the first meal storage area is lifted to the meal taking position. Each time the manipulator 2 takes a meal, it only needs to move to the meal taking position, shortening the descending stroke of the manipulator 2 and being beneficial to reducing the descending height of the manipulator 2 when taking a meal. In addition, the height position of the first conveyor belt 7 can also be adjusted by the lifting of the lifting platform 5 to make the first conveyor belt 7 flush with the second conveyor belt 8, facilitating the smooth transfer of the lunch box 100 from the second meal storage area to the first meal storage area.

[0031] Further, a first slide rail 6 is arranged on the vehicle body 1. The first slide rail extends along the vertical direction. A first slider (not shown in the figure) is arranged on one side of the first box body 3. The first slider is slidably matched with the first slide rail 6 to improve the smoothness of the lifting of the first box body 3.

[0032] Refer to Figure 2 , a first sensor 14 is arranged above the meal taking position. The first sensor 14 is used to detect whether the lifting platform 5 lifts the lunch box 100 to the meal taking position. The lifting of the lifting platform 5 is controlled by the integrated management background of the meal delivery robot. After the first sensor 14 detects that there is a lunch box 100 in the meal taking position, it sends a signal to the integrated management background of the meal delivery robot to control the lifting platform 5 to stop rising. When the first sensor 14 cannot detect the lunch box 100 in the meal taking position, it sends a signal to the integrated management background of the meal delivery robot to control the lifting platform 5 to rise.

[0033] A second sensor 15 is arranged at the meal taking end. The second sensor 15 is located below the first sensor 14. The second sensor 15 is used to detect whether the lifting platform 5 lifts the first conveyor belt 7 to a height position flush with the second conveyor belt 8.

[0034] The manipulator 2 includes a robotic arm 202 and a gripper 201 provided at the lower end of the robotic arm 202. The gripper 201 is used to grasp the food container 100 and place the food container 100 on the table. A third sensor (not shown in the figure) and a fourth sensor (not shown in the figure) are respectively provided on the robotic arm 202. The third sensor is a ranging sensor. Before the gripper 201 grasps the food container 100 and places it on the table, the distance between the gripper 201 and the table is detected by the third sensor to determine whether there are obstacles on the table and prevent the obstacles from affecting the placement of the food container 100. The fourth sensor is a diffuse reflection infrared sensor, which is used to detect whether the gripper 201 has successfully grasped the food. When grasping the food, when the food container 100 blocks the infrared ray of the diffuse reflection infrared sensor, it means that the gripper 201 has successfully grasped the food container 100; when the infrared ray is not blocked, it means that the food container 100 has not been grasped;

[0035] In one embodiment, guard plates 301 are respectively provided on both sides of the first meal storage area in the second direction (i.e., the X direction in the figure). The first conveyor belt 7 is located between the two guard plates 301, and the first direction is perpendicular to the second direction. Since the food containers 100 are stacked to a certain height in the first meal storage area, when the first box body 3 rises, it will inevitably shake. The guard plates 301 can protect the food containers 100 inside the first meal storage area and prevent the food containers 100 in the first meal storage area from tipping over.

[0036] Refer to Figure 1 , in order to make the second box body 4 move smoothly in the first direction, a guiding and sliding assembly is provided between the second box body 4 and the vehicle body 1. The guiding and sliding assembly includes a second slide rail (not shown in the figure) and a second slider 12 that cooperates with the second slide rail to slide. The second slider 12 is fixed on the second box body 4, and the second slide rail is fixed on the vehicle body 1. The second slider 12 is strip-shaped, and the length direction of the second slider 12 extends from the meal placing end towards the meal taking end. By the cooperation of the second slider 12 and the second slide rail to slide, the stability of the movement of the second box body 4 is improved.

[0037] Specifically, the vehicle body 1 includes a vehicle body 101 and a frame 102 provided on the vehicle body 101. An accommodation cavity is provided inside the frame 102. The first box body 3 and the lifting platform 5 are both provided in the accommodation cavity, and both the first box body 3 and the lifting platform 5 are far from the meal placing end. An opening is provided at one end of the accommodation cavity facing the meal placing end. One end of the second box body 4 extends into the accommodation cavity through the opening. Guiding and sliding assemblies are provided between the top of the accommodation cavity and the top of the second box body 4 and between the bottom of the accommodation cavity and the bottom of the second box body 4. By providing guiding and sliding assemblies at both the bottom and the top of the second box body 4, when moving the second box body 4, the wear of the second box body 4 can be reduced through the guiding and sliding assemblies.

[0038] Further, two sets of guiding and sliding components are provided both between the top of the accommodation cavity and the top of the second box body 4 and between the bottom of the accommodation cavity and the bottom of the box body. The two sets of guiding and sliding components on the same side of the second box body 4 are spaced along the second direction to improve the stability of the second box body 4 and prevent the second box body 4 from tilting in the accommodation cavity due to uneven force.

[0039] The frame 102 includes a framework 1021 and first baffles 1022 provided on the periphery of the framework 1021. An accommodation cavity is provided inside the framework 1021.

[0040] The vehicle body 101 is driven by electricity. A charging connector is provided on the vehicle body 101, and the power battery in the vehicle body 101 can be charged through the charging connector.

[0041] In this embodiment, a driving component 14 is connected to the bottom of the second box body 4. The driving component is used to drive the second box body 4 to reciprocate between the meal delivery end and the first box body 3. The driving component drives the second box body 4 to move in the first direction, so that the second box body 4 approaches or moves away from the first box body 3. The driving component 14 can be a motor linear movement module or a cylinder driving module, etc. Any structure that can drive the second box body 4 to move in the first direction is acceptable, and the specific structure of the driving component 14 is not limited herein.

[0042] Among them, an avoidance opening communicating with the meal taking position is provided at the top of the frame 102. The avoidance opening is used to avoid the manipulator 2, so as to reserve a position for the manipulator 2 to grab the lunch box 100 on the frame 102 and prevent the components on the frame 102 from causing position interference to the manipulator 2.

[0043] Input ports and output ports are respectively provided at the opposite ends of the second box body 4 in the first direction. The input ports and output ports are respectively communicated with the accommodation cavity. The input port is close to the meal delivery end. A door panel 9 is provided at the input port. The door panel 9 is connected to the second box body 4 through a rotating shaft 10. The rotating shaft 10 is connected with a rotating mechanism. The rotating mechanism is used to drive the rotating shaft 10 to rotate, so that the door panel 9 selectively blocks the input port. In this example, the rotating mechanism is a rotating motor. The rotation of the rotating mechanism drives the rotating shaft 10 to rotate, and then drives the door panel 9 to rotate, realizing the blocking and opening of the output port. The rotating mechanism automatically opens or blocks the output port through the control mechanism of the meal delivery robot. When it is opened, it is convenient for the staff to put the lunch box 100 into the second box body 4. When it is blocked, it can prevent the lunch box 100 inside the second box body 4 from falling from the input port.

[0044] Specifically, fixing seats 403 are provided at both the bottom and the top of the input port. Opposite ends of the rotating shaft 10 are respectively rotatably connected to the two fixing seats 403, and the rotating mechanism is arranged in one of the fixing seats 403.

[0045] In actual implementation, the meal can be automatically conveyed to the second meal storage area in the second box body 4 through an external conveyor. Specifically, the second box body 4 moves in the first direction towards the meal placement end, so that one end of the second box body 4 extends out and is connected to the output end of the conveyor outside the accommodation cavity. A camera is provided at one end of the second box body 4 having an output port, and the position of the conveyor is monitored through the camera to accurately dock the second box body 4 with the conveyor.

[0046] Specifically, the second box body 4 includes a frame body 401. The second meal storage area is arranged inside the frame body 401. A second baffle 402 is arranged on the side of the frame body 401. The frame body 401 is beneficial to enhancing the structural strength of the second box body 4.

[0047] In this embodiment, a heat preservation member 11 is arranged on one side of the second box body 4 close to the second meal storage area. Arranging the heat preservation member 11 can heat and keep warm the area around the second meal storage area, reduce heat dissipation, and is beneficial to maintaining the temperature inside the meal box 100.

[0048] In this example, the heat preservation member 11 is a heating patch, and the heating patch can generate heat to heat and keep warm the meal box 100.

[0049] In specific implementation, each layer of the second meal storage area is divided into two meal storage partitions. The two meal storage partitions on the same layer are separated by a partition 13. The meal boxes 100 in the meal storage partitions on the same layer are placed on the same second conveyor belt 8. For the convenience of description, the four meal storage partitions on the second box body 4 are respectively named as the No. 1 meal storage partition, the No. 2 meal storage partition, the No. 3 meal storage partition, and the No. 4 meal storage partition. A second meal box detector is arranged in each meal storage partition to detect whether there is a meal box 100 inside the corresponding meal distribution partition. The working process of the food delivery robot is described as follows by taking the food delivery robot delivering meals in a hotel as an example:

[0050] Step S1: The ordering staff places an order, and the order information is synchronized to the hotel food ordering management system; Step S2: The hotel food ordering management system synchronizes the information of the person ordering the meal, the meal information, and the room number to the background of the integrated management system of the food delivery robot; Step S3: The background of the integrated management system of the food delivery robot retrieves the food delivery robot to go to the food pickup area of the hotel to pick up meals; Step S4: The hotel food delivery staff views the specific content of the food delivery on the tablet APP. This content includes the food delivery robot, the food delivery room, and the schematic diagram of the placement of the food box 100. According to the specific content, the food box 100 is respectively placed into the second box body 4, and after clicking to confirm, the food delivery robot starts to execute the task. At the same time, the heat preservation part 11 in the second meal storage area is activated to heat the food box 100; Step S5: Control the second box body 4 to approach the first box body 3, so that the food box 100 inside the second box body 4 is transferred into the first box body 3, and then the second box body 4 resets. The lifting platform 5 rises until the first sensor 14 detects that there is a food box 100 at the food pickup position; Step S6: The food delivery robot autonomously plans a path to the first room point according to the correspondence between the room number and the room points set on the map. At the same time, control the manipulator 2 to move to the food pickup position to grab the food box 100. After the fourth sensor detects successful food pickup, the manipulator 2 places the food box 100 on the table. At the same time, the background of the integrated management system of the food delivery robot notifies the person ordering the meal, prompting the person ordering the meal to open the door to pick up the meal. When the manipulator 2 places the food box 100 on the table, the manipulator 2 descends to a set height, and the distance between the manipulator 2 and the table is detected by the third sensor. When the detected distance is too small, it is judged that there is a foreign object on the table, and then the manipulator 2 is controlled to move a certain distance in any direction of front, back, left, or right, and then the third sensor re-detects. If the detected distance is normal, the manipulator 2 puts down the food box 100. If it is still abnormal, an alarm message is generated and sent to the background of the integrated management system of the food delivery robot; Step S7: After the food delivery to the first room is completed, the food delivery robot will go to the second room. The manipulator 2 picks up the meal and places the food box 100 on the table (this step is similar to the actions of picking up and placing the meal in Step S7). After the meal placement is completed, control the lifting platform 5 to rise until the first sensor 14 detects that there is a food box 100 in the food pickup position; Step S8: When the first food box detector cannot detect the food box 100, it is judged that all the food boxes 100 in the first box body 3 have been delivered. Control the lifting platform 5 to descend so that the first conveyor belt 7 is flush with the second conveyor belt 8 in the 1st meal storage partition of the second box body 4. Then control the second box body 4 to approach the first box body 3, and then control the first conveyor belt 7 and the second conveyor belt 8 to drive, transferring the food box 100 in the 1st meal storage partition to the first box body 3. When the second food box detector in the second meal storage area cannot detect the food box 100 and the first food box detector in the first meal storage area detects the food box 100, it is judged that the transfer of the food box 100 is successful, and the conveyor belt stops conveying.The steps of transferring the lunch boxes 100 in the 2nd, 3rd, and 4th lunch box storage areas to the first box body 3 are similar to the steps of transferring the lunch boxes 100 in the 1st lunch box storage area, and will not be elaborated here. When the delivery robot has completed the delivery of all the lunch boxes 100 inside the box body, the heat preservation component 11 is closed.
