[0056] The above-mentioned grippers 61 are electric grippers or pneumatic grippers, preferably electric grippers.

[0057] The working principle of the present invention is as follows: Put the tea-boiling bags corresponding to different types into the material trays, and multiple unit portions of tea-boiling bags can be placed in each material tray; When it is necessary to boil tea, pure water is injected into each tea-boiling bucket through the water inlet pipe and the branch pipe. Then, the robotic arm on the movable plate is successively moved to the operable area near each tea-boiling bucket. Finally, the corresponding tea bag is placed into the opened tea-boiling bucket by the gripper on the robotic arm. After closing the lid of the tea-boiling bucket, the tea-boiling process starts. Different tea-boiling temperatures are set according to the types of tea leaves in the tea bag (generally between 80°C and 90°C). Here, the tea-boiling bucket can be purchased with a built-in heating function, or a heating base can be installed under the bucket to achieve the tea-boiling operation. There are already mature products available in the prior art, which will not be elaborated here; After the tea-boiling is completed, various original teas required for preparing milk tea are obtained. At this time, the lids of each tea-boiling bucket are opened, and the robotic arm is driven to move by the movable plate, so that the gripper of the robotic arm successively adds the ice cubes in the ice maker at one end into each tea-boiling bucket, quickly cooling the relatively high-temperature original tea in the tea-boiling bucket to a relatively low temperature (generally between 30°C and 40°C) to meet the requirements for subsequent milk tea preparation; Whether the tea-boiling operation is required is controlled by the PLC controller in cooperation with the liquid level sensor in the insulation bucket. When half of the original tea in the insulation bucket remains, a new round of tea-boiling operation is started.

[0058] The original tea liquids of various flavors that have been boiled and cooled to the appropriate temperature are pumped into the corresponding insulation buckets through the feeding pipe. At the same time, various liquid ingredients are respectively put into each ingredient bucket. The time for pumping the original tea liquid into the insulation bucket is also controlled by the PLC controller in cooperation with the liquid level sensor in the insulation bucket. When one-fifth of the original tea in the insulation bucket remains, the pumping of the original tea liquids of various flavors that have been boiled and cooled to the appropriate temperature from the tea-boiling bucket into the insulation bucket is started; When it is necessary to prepare milk tea, the milk tea cups are successively placed on the conveyor belt and the bottom of the cup is embedded in the cup holder on the conveyor belt to ensure the stability of the automatic movement of the milk tea cups. Each empty milk tea cup successively passes under the three discharge valves and the two discharge bases as the conveyor belt moves. Then, the PLC controller drives the opening and closing of each pumping component, electromagnetic solenoid valve, rotor pump, and discharge valve. First, at least one type of granular ingredient required is injected into the milk tea cup from the lower end of the discharge valve, and then the required pure water, original tea liquid, and at least one ingredient are injected downward into the milk tea cup from the discharge port at the lower end of the discharge nozzle to obtain the prepared finished milk tea; When it is necessary to package the milk tea, the finished milk tea on the conveyor belt is picked up by the second robotic arm and placed in the packaging machine for packaging, thus completing the packaging of the milk tea.

[0059] When the above-mentioned automatic tea beverage machine is adopted, it can replace manual labor to automatically realize the automated processing of the original tea necessary for milk tea preparation, and automatically and continuously realize the preparation and transportation of milk tea with multiple flavors. Moreover, it can achieve any combination of discharging of the original tea bases with multiple flavors and multiple ingredients, reduce the manpower required in the milk tea production process, improve the production efficiency, and reduce the material waste and the reduction of milk tea quality caused by human errors. In addition, the obtained original tea has good freshness and taste, and can also ensure the quality and consistency of the finished products.

[0060] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
