Description

Technical Field

[0001] The utility model relates to a structural improvement of an intelligent food delivery system. Background Art

[0002] The AGVs in traditional intelligent food delivery systems only have the function of forward unidirectional movement, and their operation relies more on relatively straight tracks. Therefore, the tracks are not easy to design flexibly, and the space required for track layout is large. In addition, traditional AGVs in food delivery systems all use electromagnetic navigation, and metal wires need to be buried under the tracks. Not only is laying the wires troublesome, but changing and expanding the track path is also difficult, and the cost of the required materials is also relatively high. It can be seen that the traditional intelligent food delivery system is not conducive to cost savings and flexible track design, and does not help to optimize the table layout and improve the space utilization and flexibility of the dining venue. Utility Model Content

[0003] The utility model aims to provide a food delivery robot system which can optimize the layout of dining tables and improve the space utilization and flexibility of dining places.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] The food delivery robot system includes a track and a delivery robot installed on the track. The delivery robot includes a mobile chassis for carrying food. The bottom of the mobile chassis is provided with a drive component for driving it to move back and forth along the track; it also includes an RFID positioning system. The RFID positioning system includes an RFID electronic tag attached to the track and an RFID reader / writer installed on the delivery robot.

[0006] As a preferred solution, the track is a double-track track and is installed on the tabletop of the dining table.

[0007] As a preferred solution, the drive assembly includes a drive box fixedly mounted on the outer bottom of the mobile chassis, a drive motor with left and right double-output shafts is fixedly provided in the center of the inner bottom surface of the drive box, the drive motor is a bidirectional rotating motor and drive wheels are symmetrically provided on the output shafts on both sides thereof, the drive wheels are partially exposed below the drive box through the wheel holes provided along the bottom surface of the drive box, and guide wheels are symmetrically provided on the left and right sides of the drive box; the delivery robot is placed between the double tracks of the track so that the drive wheels contact and connect to the table top of the dining table, and the guide wheels contact and connect to the track on the same side.

[0008] As a preferred solution, the number of drive assemblies is set to one or two sets according to the length of the drive box.

[0009] As a preferred solution, a set of drive components is centrally located at the bottom center of the mobile chassis.

[0010] As a preferred solution, the two sets of drive assemblies are centered left and right and spaced apart front and back at the bottom of the mobile chassis.

[0011] As a preferred solution, a food cover for covering food is provided on the outer top of the movable chassis, and the food cover is provided with an electric cover plate that can be opened from the left and right sides.

[0012] As a preferred solution, the drive assembly also includes a power battery arranged inside the mobile chassis, and the side wall of the mobile chassis is provided with a battery replacement door for facilitating the disassembly and replacement of the power battery.

[0013] As a preferred solution, the delivery robot is also provided with an on-board controller, which is electrically connected to the RFID reader, drive motor and power battery.

[0014] As a preferred solution, it also includes a control center, a POS terminal ordering screen and a kitchen terminal meal transmission screen. The control center is connected to the POS terminal ordering screen, the kitchen terminal meal transmission screen and the vehicle controller through a wireless communication network.

[0015] The utility model has the following beneficial effects:

[0016] 1. The delivery robot has the ability to move forward and backward in both directions on the track. This function enables the delivery robot to operate and navigate in narrow passages and corners, making the track laying less restricted by space, which is conducive to optimizing the table layout and thus improving the space utilization and flexibility of the dining venue.

[0017] 2. The delivery robot uses an RFID system for positioning and navigation. The RFID system not only has the advantages of more accurate positioning and lower material costs, but its RFID electronic tags can be affixed to the tabletops within the track without relying on professional technology, making the track path easier to lay, change or expand.

[0018] 3. The delivery robot is equipped with a food cover that can be opened on both sides, which makes it easy to put food in and out from both sides of the track. This will further facilitate the laying of the track and optimize the table layout, thereby improving the space utilization and flexibility of the dining place.

[0019] 4. The control center can be seamlessly integrated with the delivery robot, POS terminal ordering screen and kitchen terminal food delivery screen. After the kitchen places the food on the delivery robot, the food can be automatically delivered to the designated table. This simplified process reduces manual operations and speeds up service speed and efficiency.

[0020] 5. The delivery robot is equipped with replaceable batteries, which helps minimize downtime, ensure continuous operation, and improve service speed and efficiency.

[0021] 6. According to the length of the track and the needs, more than one delivery robot can be configured on the same track at the same time, which is conducive to increasing service throughput and further improving service speed and efficiency.

[0022] 7. The delivery robot can resume operation from anywhere on the track, making it flexible and easy to use.

[0023] 8. It has a wide range of applications and can use advanced robotics technology to provide intelligent delivery services for various dining places such as fast food restaurants, cafes and food courts, which is conducive to improving customer consumption experience.
