[0007] When in use, in the initial state, the lifting spring is in an extended state, the soaking cylinder is located inside the passivation cylinder, the connecting port and the soaking cylinder are vertically arranged, the fixed annular electromagnet is energized to generate magnetism, the fixed annular electromagnet and the sliding annular magnet are arranged with the same pole, the fixed annular electromagnet is fixed to the bottom inner wall of the passivation cylinder and pushes the sliding annular magnet through repulsion, the sliding annular magnet drives the sliding plate to slide up through the motor box, the sliding plate drives the locking plate to fit with the top wall of the passivation cylinder, the air inside the passivation cylinder is pushed out by the sliding plate through the connecting port, the steering motor drives the locking plate to rotate through the power end, the locking plate rotates away from the opening of the soaking cylinder, and the passivation liquid is injected into the soaking cylinder, and the passivation liquid occupies half of the space inside the soaking cylinder.

[0008] Preferably, the rotary seal type immersion mechanism includes a wheel disc, a clamping frame and a fixing bolt, the wheel disc is arranged on the inner wall of the connecting port, the wheel disc is threadedly connected to the connecting port, the clamping frame is arranged on the bottom wall of the wheel disc, the fixing bolt is arranged at one end of the clamping frame away from the wheel disc, and the fixing bolt is threadedly connected to the clamping frame.

[0009] When in use, fix the robot shaft component to the inside of the clamping frame, rotate the fixing bolt, the fixing bolt moves away from the clamping frame, the distance between the fixing bolt and the top wall of the clamping frame increases, place the robot shaft component between the fixing bolt and the top wall of the clamping frame, rotate the fixing bolt, the fixing bolt approaches the clamping frame, the fixing bolt fixes the robot shaft component to the clamping frame, the wheel drives the robot shaft component through the connecting port through the clamping frame and places it into the soaking cylinder, the wheel is rotated into the connecting port, fixes the robot shaft component inside the soaking cylinder, the robot shaft component and the clamping frame occupy the space inside the soaking cylinder, the liquid level of the passivation liquid inside the soaking cylinder rises, and the robot shaft component can be completely immersed.

[0010] Specifically, the heat treatment mechanism includes a heating tube, a heat-conducting copper rod, a radiation copper plate, a metal rod and a heating coil. Multiple groups of the heating tubes are arranged on the side wall of the passivation tube, multiple groups of the radiation copper plates are arranged through the side of the passivation tube close to the heating tube, the heat-conducting copper rod passes through the heating tube and is arranged on the side wall of the radiation copper plate, the metal rod is arranged inside the heating tube, and the heating coil is arranged on the inner wall of the heating tube outside the metal rod.

[0011] When in use, after the robot shaft component is immersed and passivated, the direction of the current passed into the fixed annular electromagnet changes, so that the magnetic pole of the fixed annular electromagnet changes, and the fixed annular electromagnet and the sliding annular magnet are set with different poles. Under the weight of the weighted ball, the sliding plate slides down along the inner wall of the passivation cylinder by utilizing the elastic deformation of the lifting spring. As the sliding plate descends, the air inside the passivation cylinder is discharged through the extension port, and the sliding plate drives the soaking cylinder to extend out of the passivation cylinder, and the soaking cylinder is away from the robot shaft component, and the robot shaft component is exposed inside the passivation cylinder. At this time, the inside of the passivation cylinder above the sliding plate is The internal pressure is reduced, and the sliding plate drives the weighted ball to extend out of the passivation cylinder through the extension port to dry the robot shaft components exposed inside the passivation cylinder. The heating coil is energized to heat the metal rod, and the temperature inside the heating cylinder rises. The heating cylinder conducts the temperature to the inside of the radiation copper plate through the heat-conducting copper rod, and the radiation copper plate heats the negative pressure space inside the passivation cylinder. After the temperature inside the passivation cylinder rises, the passivation liquid remaining on the surface of the robot shaft components is dried. The passivation liquid on the surface of the robot shaft components evaporates into water vapor and remains in the negative pressure space of the passivation cylinder, which prevents the evaporated harmful water vapor from leaking to the outside of the passivation cylinder. To ensure the safety of the operators, when the robot shaft components are completely exposed inside the passivation cylinder, the current passed into the fixed annular electromagnet no longer changes, the magnetic field strength between the fixed annular electromagnet and the sliding annular magnet remains unchanged, the sliding plate stops descending, and the internal space of the passivation cylinder above the sliding plate is in a negative pressure state, causing the level of the passivation liquid inside the immersion cylinder to rise. The passivation liquid inside the immersion cylinder is in a semi-water state, so that the passivation liquid will not overflow from the immersion cylinder. The steering motor drives the locking plate to rotate through the power end, and the locking plate seals the opening of the immersion cylinder. Then The pressure sensor monitors the air pressure inside the passivation cylinder through the detection end. When the passivation liquid on the surface of the robot shaft component is evaporated, the air pressure inside the passivation cylinder above the sliding plate gradually increases. After the robot shaft component is dried, the steam extraction pump draws the harmful water vapor inside the passivation cylinder into the activated carbon adsorption cylinder through the steam extraction pipe for purification, and the water vapor purified by the activated carbon adsorption cylinder is discharged. When the pressure sensor monitors that the air pressure inside the passivation cylinder is reset to the air pressure value when no water vapor is generated, the steam extraction pump stops the steam extraction operation inside the passivation cylinder to complete the drying of the passivated robot shaft component.

[0012] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, this solution adopts a sliding passivation treatment method. By setting up a pull-down liquid-carrying mechanism, a rotary-sealed immersion mechanism and a heat treatment mechanism, the sliding mechanism, the steering mechanism, the pull-down mechanism, the weight-increasing mechanism and the exhaust mechanism cooperate with each other to prevent the harmful gases released by the chemical reaction in the passivation liquid from leaking to the outside during the passivation treatment of the robot shaft parts, and can dry the robot shaft parts after the passivation treatment. On the one hand, it removes the residual moisture on the surface of the parts to prevent the moisture from affecting the formation of the passivation film, ensuring that the passivation film can cover the metal surface evenly and densely. On the other hand, it can prevent the passivation liquid from spilling into the external environment to ensure the safety of the operators. At the same time, through The negative pressure space formed after the immersion cylinder extends out of the passivation cylinder can effectively reduce the probability of active water vapor after heating diffusing to the outside, thereby improving the passivation efficiency of the robot axis components to a certain extent, and drying the robot axis components exposed to the inside of the passivation cylinder, and the heating coil is energized to heat the metal rod. The temperature inside the heating cylinder rises, and the heating cylinder conducts the temperature to the inside of the radiation copper plate through the heat-conducting copper rod. The radiation copper plate heats the negative pressure space inside the passivation cylinder. After the temperature inside the passivation cylinder rises, the passivation liquid remaining on the surface of the robot axis components is dried, and the passivation liquid on the surface of the robot axis components evaporates into water vapor and remains in the negative pressure space of the passivation cylinder, thereby preventing the evaporated harmful water vapor from leaking to the outside of the passivation cylinder.

The wheel 24 is screwed into the connecting port 23 to fix the robot shaft component in the soaking cylinder 33. The robot shaft component and the clamping frame 25 occupy the space inside the soaking cylinder 33, and the liquid level of the passivation liquid inside the soaking cylinder 33 rises, so that the robot shaft component can be completely immersed. After the robot shaft component is immersed and passivated, the direction of the current passed into the fixed annular electromagnet 13 changes, so that the magnetic pole of the fixed annular electromagnet 13 changes, and the fixed annular electromagnet 13 and the sliding annular magnet 12 are arranged with different poles. Under the weight of the weighted ball 15, the sliding plate 4 slides and descends along the inner wall of the passivation cylinder 1 by utilizing the elastic deformation of the lifting spring 5. As the sliding plate 4 descends, the air inside the passivation cylinder 1 is discharged through the extension port 16, and the sliding plate 4 drives the soaking cylinder 33 to extend out of the passivation cylinder 1.
