[0063] Step S4, while the cleaning assembly cleans the dust of the electric permanent magnetic chuck, the staff starts the cooling assembly to make the air flow quickly, at this time, the air flow quickly forms the wind force, and the wind force cools and lowers the temperature of the electric permanent magnetic chuck by heat convection.

[0064] Step S5, finally, when the inside of the dust collecting assembly is full of dust or impurities, the staff pulls out the dust collecting assembly from the bottom of the electric permanent magnetic chuck, and cleans the dust and impurities in the inside of the dust collecting assembly for subsequent use.

[0065] In the step S4, further comprising the following steps:

3. The electro-permanent magnet chuck with multi-sensor fusion according to claim 1, characterized in that: The inner side of the limiting component is inlaid with a cleaning component, which is used to clean the dust and impurities on the top of the electro-permanent magnet chuck.

4. The electro-permanent magnet chuck with multi-sensor fusion according to claim 3, characterized in that: A cooling component is installed at the bottom of the cleaning component and is located on top of the moving component. The cooling component is used to cool the electro-permanent magnet chuck that is too hot.

5. The electro-permanent magnet chuck with multi-sensor fusion according to claim 1, characterized in that: The bottom of the electromagnetic base (1) is equipped with a dust collection component, which is used to collect the dust and impurities cleaned by the cleaning component.

6. A control method for a multi-sensor fusion electro-permanent magnet chuck, applicable to the multi-sensor fusion electro-permanent magnet chuck described in any one of claims 1-5, wherein the control method for the electro-permanent magnet chuck is as follows: Step S1: First, the staff inserts the external power plug into the inside of the electro-permanent magnet chuck to power on the electro-permanent magnet chuck and start it together with the magnetic suction module. At the same time, the electromagnetic unit and the sensing unit in the magnetic suction module are running, and the sensing unit monitors the current and temperature of the electromagnetic unit. Step S2: Then, the staff member holds the limiting component in the positioning mechanism and moves it to the position where the object needs to be positioned through the moving component. Finally, the staff member holds the object and places it on top of the electro-permanent magnet chuck through the limiting component for subsequent use. Step S3: While the staff moves the limiting component, the cleaning component is activated to clean the dust and impurities on the top of the electro-permanent magnet chuck. Then, the dust and impurities fall through the inside of the moving component and are stored inside the dust collection component. Step S4: While the cleaning component is cleaning the dust from the electro-permanent magnet chuck, the staff activates the cooling component to make the air circulate rapidly. At this time, the rapid air circulation forms wind, which cools the electro-permanent magnet chuck by heat convection. Step S5: Finally, when the inside of the dust collection component is full of dust or impurities, the staff will pull the dust collection component out from the bottom of the electro-permanent magnet chuck and clean the dust and impurities inside the dust collection component for subsequent use.

7. The control method for a multi-sensor fusion electro-permanent magnet chuck according to claim 6, characterized in that: Step S4 further includes the following steps: Step S41: While the operator moves the positioning component using the moving component, the operator monitors the current and temperature of the electromagnetic unit through the sensing unit in the magnetic module. When the temperature of the electro-permanent magnet module is too high, the operator activates the cooling component. The cooling component uses wind power and a bag of cold water to cool the electro-permanent magnet chuck by utilizing the property that water has the highest specific heat capacity. The heat convection formula is Q=mcp(t2-t1).
