Description

Intelligent food delivery robot

technical field

The invention belongs to the field of food delivery vehicles, in particular to an intelligent food delivery robot.

Background technique

In recent years, with the rapid development of the catering industry and the growth of modern people's spiritual consumption needs, hotels and catering industries have introduced automatic food delivery robots, which not only improves the efficiency of food delivery services, but also brings considerable benefits. Consumers add a comfortable way of enjoying and entertaining while enjoying the dishes.

However, among the more common food delivery robots currently on the market, most of them are just to meet the needs of fun and entertainment, and the actual food delivery capabilities are far from meeting the requirements. For example, in December 2010, a restaurant using a food delivery robot appeared in Jinan. The robot has a novel appearance, but it can only carry one plate at a time, which is not efficient.

In addition, during the delivery process, the cleanliness and sanitation of the dishes cannot be guaranteed due to the exposed plates. Therefore, the practicability of the meal delivery robot is not high.

After retrieval, the Chinese patent with the publication number CN2598427 provides a closed food delivery car, which is equipped with casters on the bottom of the cabinet, handrails on the end of the cabinet, and a The openable top cover is provided with a mezzanine on the side of the cabinet, and a transmission device is installed in the interlayer, and the crank handle installed outside the cabinet is connected with the transmission device. A side door is provided on the cabinet wall opposite to the conveyor belt. Due to the sealed top of such a closed food delivery car, the main way of contamination of food by external dirt is cut off, so the spread of diseases can be reduced, which is greatly beneficial to the health of diners. However, the location of the dishes is too low, impersonal, and there is only one conveyor belt in the food delivery car, so the space utilization rate in the car is very low.

Moreover, guard plates are fixed on the outer sides of the columns.

And the platform on one side of the meal delivery motor is equipped with a solenoid valve for horizontally adjusting the positions of the meal delivery gear and the meal delivery motor.

Advantage and positive effect that the present invention adopts are:

1. The food delivery robot can adjust the position of the tray to ensure that it can adapt to the needs of tables of different heights. The compatibility with tables of different specifications has been significantly improved, and the application range is wide.

2. The food delivery robot adopts a chain sprocket-coordinated vertical transmission device, and multiple bosses are arranged at intervals on each vertical transmission chain, and each four bosses on the same horizontal plane is a group, and each group of bosses Synchronized with the sprocket and chain transmission, thus maintaining the stability of each plate when lifting, and at the same time, multiple sets of bosses can realize the transmission of multiple plates.

3. The output shaft of the push-out motor in the push-out device of the meal delivery robot is provided with a gear, and the bottom of the dinner plate is provided with a rack meshing with the gear, so that the dinner plate can be pushed horizontally from the car body to the dining table smoothly. Eject the motor through the electromagnetic valve to regulate its horizontal position, thus when the meal delivery car reclaims the meal tray, the motor will be released to avoid the position, thereby preventing the ejection motor from blocking the rotation of the meal tray and affecting the meal tray from falling into the storage tray.

4. The detector of this food delivery robot uses Hall elements to identify the trajectory hidden by ultra-thin magnetic materials on the restaurant floor, so as to ensure that the robot can travel to the designated table according to the route designed by the designated program to complete the push of the meal plate .

5. The detector of this food delivery robot has a built-in ultrasonic detection module, which can immediately monitor whether the road within 5 meters in front of the robot is unblocked. By editing and inputting relevant programs, it can satisfy pedestrian avoidance, thus ensuring its safe use.
