[0031] Advantageously, a plurality of limiting rods 32 are disposed in the cup holder 26 , and a clamping plate 31 is disposed on the outer surface of the limiting rod 32 . The inner side of the clamping plate 31 is in an inclined conical shape for clamping the cup 12 .

[0032] Advantageously, an infrared sensor 42 is further disposed in the cup holder 26 , and the infrared sensor 42 is used to identify whether the cup 12 is placed therein.

[0033] Advantageously, the beverage machine 15 is also included, in which the mobile platform 11, the water injection rod 13 and the lifting assembly 14 are arranged. A plurality of material boxes 16 are arranged in the beverage machine 15, and the mobile platform 11 drives the cup 12 to receive the powder squeezed out of the material box 16 at the lower side of the material box 16 at different positions.

[0034] The working process of the equipment is as follows: In the first step, according to the recipe production order of the beverage, the mobile platform 11 is moved to the material boxes 16 corresponding to each specified coordinate to receive powder. The amount of powder received is weighed by the electronic scale 34 under the cup holder 26. When the weight of the powder reaches the set amount, an electric rotation instruction to stop discharging is issued to stop the material box 16 from working, and so on, until all the material boxes 16 are connected and the materials are discharged.

[0035] Advantageously, when the mobile platform drives the cup 12 to move below the material box 16 and the water filling rod 13, the electronic scale 34 is automatically reset.

[0036] In the second step, the mobile platform 11 drives the cup 12 to move to the water injection rod 13. After the stirring and water injection module works, the water inlet valve is opened, the electromagnetic pump and the pneumatic air pump are started, the duct fan is started, and the water injection rod 13 moves downward. According to the set water volume, the water volume is measured by the flow meter to stir the instant powder in the cup.

[0037] In the third step, during stirring, the mobile platform 11 drives the cup 12 to move along the X-axis and the Y-axis, so that the cup 12 moves relative to the water injection rod 13, so that the water injection rod 13 can fully stir the beverage in the cup 12 while remaining stationary.

[0038] In the fourth step, when the water volume is reached, the water injection pump is reset, the two-position three-way valve is opened, and the water injection head is cleaned. After the cleaning is completed, the water system is stopped, the air pump is stopped, the pipeline motor is stopped, and the mobile platform 11 moves the cup 12 to the next process.

[0039] When the device is working, the cup 12 is placed on the tray 36, and the electronic scale 34 provides real-time feedback of the weight change in the cup 12. Then the X-axis module 28 drives the Y-axis slider 23 to move along the Y-axis direction. After the Y-axis module 22 is installed on the Y-axis slider 23, it also moves along the Y-axis direction. Then the Y-axis module 22 drives the bracket 27 and the cup 12 to move along the X-axis direction, so that the cup 12 can be driven to the lower side of the material box 16 at different positions, and the cup 12 can also be driven to the lower side of the water injection rod 13.

[0040] When the cup 12 moves to the lower side of the material box 16, the data of the electronic scale 34 is reset, and then the powder squeezed out of the material box 16 falls into the cup 12. The resulting weight change is the weight of the powder, thereby determining the powder ratio.

[0041] After the proportions of the various powders in the cup 12 are completed, the mobile platform 11 drives the cup 12 to move to the lower side of the water injection rod 13. Thereafter, the lifting assembly 14 drives the water injection rod 13 to move downward, so that the water injection rod 13 extends into the cup 12, and then water and air are injected. The electronic scale 34 provides real-time feedback on the amount of gas-liquid mixture added, and stops injecting water after reaching a predetermined amount.

[0042] Afterwards, the X-axis module 28 and the Y-axis module 22 in the mobile platform 11 are linked with each other on the Y-axis and the X-axis, so that the bracket 27 drives the cup 12 to perform a compound movement, so that when the water filling rod 13 remains stationary, the beverage in the cup 12 can be fully stirred, and the water filling rod 13 can be moved between eight positions, that is, it performs a circular motion around the stirring rod, with one coordinate point every forty-five degrees, a total of eight coordinate points, and just one circle, to drive the cup to move.

[0043] After the stirring is completed, the water injection rod 13 is reset upwards under the drive of the lifting assembly 14 after being rinsed.

[0044] The above are only specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention; therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
