[0002] Buffet generally refers to a dining method where no formal meal is prepared, but diners can choose their own food and drinks at will. With the diversification of life, buffets have gradually moved from the initial business activities to daily life, and with the further support and empowerment of intelligent technology, it has evolved into a self-service ordering and automatic delivery operation mode. For example, the public patent with application number 201810323689.X proposes that "the customer orders through the ordering terminal device 1, the kitchen display screen 3-1 receives the order information sent by the ordering terminal device 1, and the kitchen receives the order, prepares the dishes, The dishes are directly placed on the food delivery cart 2 after they are prepared. The kitchen staff presses the food delivery button 3-2, and the kitchen end display screen 3-1 displays the table number and the dishes ordered by the customer. The food delivery cart 2 delivers the dishes from the kitchen to the restaurant. Each table can order dishes at the same time. The food delivery cart 2 delivers the dishes ordered by the table number directly, and when the food delivery cart 2 arrives at the designated food delivery location, a voice prompt is issued to the outside world to remind the customer to take the food. When the food delivery cart 2 arrives at the designated food delivery location, the timing unit 23 starts timing. When the timing time reaches the preset value, the controller 21 controls the food delivery cart 2 to return along the original route.

The meshing transmission component 7 drives a composite transmission shaft 5 to rotate synchronously through the first gear 6, and then links the three composite transmission shafts 5 and the conveyor belt 3, and finally makes the conveyor belt 3 reciprocate, so as to meet the subsequent use conditions of taking food at multiple positions.

[0031] A receiving platform 4 is connected to the top of the conveyor belt 3, and the receiving platform 4 can reciprocate synchronously with the conveyor belt 3. The food tray 10 is placed on the top surface of the receiving platform 4. The receiving platform 4 includes a transition rod 41, a receiving sleeve plate 42, and a magnet sheet 43. The two ends of the transition rod 41 are respectively fixedly connected to the top of the conveyor belt 3 and the bottom of the transition rod 41. The magnet sheet 43 is nested on the inner side of the top of the receiving sleeve plate 42. The top surface of the magnet sheet 43 is coplanar with the top surface of the receiving sleeve plate 42. The number of receiving platforms 4 is not less than two and is equidistantly distributed on the top of the conveyor belt 3. In addition to providing stable support for the food tray 10, the receiving platform 4 also ensures the connection strength between the receiving platform 4 and the food tray 10 by magnetic attraction.

[0032] An outer protective shell 8 and an inner closed component 9 are installed on the top of the automatic guided transport vehicle 1. The outer protective shell 8 and the inner closed component 9 are movably connected to the outer side and the inner side of the conveyor belt 3 respectively. The outer protective shell 8 and the inner closed component 9 are combined to form a protective space. The protective space covers four composite transmission shafts 5, a fixed frame 2, a first gear 6, and a meshing transmission component 7.

Due to the existence of the receiving sleeve plate 42, the connection strength between the receiving platform 4 and the food tray 10 is enhanced by magnetic attraction.

[0035] Next, the automatic guided transport vehicle 1 drives the entire device to move automatically along the set route. At the same time, the brake servo motor 71 inside the meshing transmission component 7 is started, and the output end of the brake servo motor 71 drives the second gear 72 to mesh and transmit the first gear 6, so that the first gear 6 drives a relative composite transmission shaft 5 to rotate synchronously, and then, under the support and auxiliary transmission of the remaining three composite transmission shafts 5 and the fixed frame 2, the conveyor belt 3 drives multiple receiving platforms 4 and food trays 10 to reciprocate and rotate, thereby providing multi-position and multi-directional pick-up and placement conditions when approaching guests for dinner, fully optimizing the use effect.
