[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] Example 1: Figures 1 to 3 A quantitative powder seasoning adding device for a cooking robot comprises a silo 3, a bracket 2 and a material receiving mechanism; the bracket is fixed on a frame 1, and a supporting ring 22 is provided on the bracket, and the silo is placed in the supporting ring (the silo edge 31 at the top of the silo is just clamped on the supporting ring); the material receiving mechanism is located below the silo; the bottom of the silo is an inverted cone;

[0022] A dividing wheel 5 driven by a stepping motor is provided at the discharge port (i.e., the bottom opening) of the silo; the dividing wheel is provided with at least 6 dividing grooves 51; and the 6 dividing grooves are arranged at equal intervals on the outer periphery of the dividing wheel (i.e., arranged equally along the circumference of the dividing wheel).

[0023] When the indexing groove does not contact the inner wall of the discharge port, the indexing wheel can block the discharge port to prevent the seasoning from falling out; driven by the stepper motor, the indexing wheel rotates, and the indexing groove on the indexing wheel can discharge the powder seasoning in the silo;

[0024] The material receiving mechanism includes a material receiving cup 6 and a swing arm 9 for feeding; the material receiving cup is fixed on the swing arm; the swing arm is installed on a rotating shaft driven by a swing arm driving motor; the swing arm driving motor drives the swing arm to drive the material receiving cup to swing to one side to implement the feeding action (put the seasoning into the pot body).

[0025] A drying ball 4 is provided in the silo (the drying ball is a hollow plastic ball, which has a bag containing a desiccant to ensure the drying of the seasoning, and the bag can prevent the desiccant from entering the silo. The drying ball is optional and is only used when necessary).

[0026] The support ring is provided with four weighing sensors 23, which are arranged at equal intervals along the circumference of the support ring; a controller is also included, and the weighing sensors are connected to the ADC interface of the controller, so that the controller can collect the data of weight change, and the stepper motor and the swing arm drive motor are controlled by the controller. The controller can be a single chip microcomputer, DSP or PLC controller.

[0027] A stop rod 8 is also provided on the frame. The stop rod is located below the swing arm and on the side facing the pot body, and is used to provide a limit for the rotation of the swing arm.

[0028] Working process description:

[0029] In the initial state, if Figure 1 , the indexing groove avoids the discharge port, the stepper motor does not work, and the indexing wheel remains stationary; the receiving cup is located directly below the discharge port;

[0030] Loading steps: The stepper motor rotates to drive the indexing wheel to rotate, so that the seasoning is taken out of the silo and falls into the receiving cup. At this time, the controller monitors the real-time change of the total weight of the silo through the weighing sensor. Once the discharge amount reaches the preset amount, the controller drives the indexing wheel to rotate to the position where the indexing groove avoids the discharge port and stops;

[0031] Feeding steps: The controller controls the swing arm to rotate quickly. When it rotates to the lowest position (that is, the position blocked by the blocking rod), the seasoning in the receiving cup on the swing arm is quickly poured into the pot body. After stagnating for several seconds (such as 3 seconds), the swing arm resets and waits for the next feeding.

[0032] The above control process is implemented under the control of the controller and is an existing mature technology, so this solution does not contain method features.
