Description

Technical Field

[0001] The present invention belongs to the technical field of passivation treatment, and specifically refers to a passivation treatment device for robot components. Background Art

[0002] Passivation treatment is a process of forming an extremely thin and dense protective film on the metal surface through chemical or electrochemical methods. This protective film can effectively prevent the metal from reacting with the external environment (such as air, water, etc.), thereby achieving the effects of anti-corrosion and wear resistance. For robot components, passivation treatment can significantly improve their corrosion resistance, reduce damage caused by environmental factors, and at the same time improve the wear resistance of the components to ensure the stable operation of the robot in a complex working environment.

[0003] Currently, the existing passivation treatment devices for robot components have the following problems:

[0004] When the existing passivation treatment devices for robot components use chemical methods for passivation treatment, it is easy for the harmful gases generated during the chemical reaction of the passivation liquid to leak into the external environment, posing a serious threat to the safety of the operators. Moreover, the traditional passivation treatment devices for robot components do not have the ability to dry the passivated components. Therefore, they cannot meet the current usage requirements for passivation treatment devices for robot components. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, this solution provides a passivation treatment device for robot components that can prevent the harmful gases generated during the chemical reaction of the passivation liquid from leaking into the external environment, ensure the safety of the operators during operation, and can dry the components after passivation treatment.

[0006] The technical solution adopted in this solution is as follows: A passivation treatment device for robot components proposed in this solution includes a passivation cylinder, a downward-pulling type liquid-carrying mechanism, a rotary-sealing type soaking mechanism, and a heat treatment mechanism. The downward-pulling type liquid-carrying mechanism is arranged inside the passivation cylinder, the rotary-sealing type soaking mechanism is arranged on the upper wall of the passivation cylinder, the heat treatment mechanism is arranged on the side wall of the passivation cylinder. The downward-pulling type liquid-carrying mechanism includes a sliding mechanism, a steering mechanism, a downward-pulling mechanism, a weight-increasing mechanism, and an exhaust mechanism. The sliding mechanism is arranged on the inner wall of the passivation cylinder, the steering mechanism is arranged on the bottom wall of the sliding mechanism, the downward-pulling mechanism is arranged on the side of the steering mechanism away from the sliding mechanism, the weight-increasing mechanism is arranged on the side of the steering mechanism close to the downward-pulling mechanism, and the exhaust mechanism is arranged on the side wall of the passivation cylinder.

[0007] As a further preference of the solution of this case, the sliding mechanism includes a sliding plate, a lifting spring, an immersion port, a connection port and an immersion cylinder. The sliding plate is slidably arranged on the inner wall of the passivation cylinder. The lifting spring is arranged between the sliding plate and the inner bottom wall of the passivation cylinder, and the lifting spring is in an extended state. A plurality of the immersion ports are arranged on the inner wall of the sliding plate. The immersion cylinder is arranged on the inner wall of the immersion port, and the immersion cylinder is provided with an open upper end. A plurality of the connection ports are arranged on the upper wall of the passivation cylinder. The steering mechanism includes a motor box, a steering motor and a locking plate. The motor box is arranged on the bottom wall of the sliding plate. The steering motor is arranged inside the motor box. The locking plate is fitted on the upper wall of the sliding plate. The power end of the steering motor passes through the motor box and the sliding plate and is connected to the bottom wall of the locking plate. The pulling-down mechanism includes a sliding ring magnet and a fixed ring electromagnet. The sliding ring magnet is arranged on the bottom wall of the motor box. The fixed ring electromagnet is arranged on the bottom wall of the passivation cylinder below the sliding ring magnet. The weight-increasing mechanism includes a weight ball and an outlet. The weight ball is arranged on the bottom wall of the motor box inside the sliding ring magnet. The outlet is arranged on the bottom wall of the passivation cylinder inside the fixed ring electromagnet. The exhaust mechanism includes an activated carbon adsorption cylinder, an air extraction pump, an air extraction pipe and a pressure sensor. A plurality of the activated carbon adsorption cylinders are arranged on the side wall of the passivation cylinder. The air extraction pump is arranged on the bottom wall of the activated carbon adsorption cylinder. The exhaust end of the air extraction pump is communicated with the bottom wall of the activated carbon adsorption cylinder. The air extraction pipe is communicatively arranged between the passivation cylinder and the air extraction end of the air extraction pump. The pressure sensor is arranged on the upper wall of the passivation cylinder, and the detection end of the pressure sensor passes through and is arranged inside the passivation cylinder.

[0008] During use, in the initial state, the lifting spring is in an extended state. The immersion cylinder is located inside the passivation cylinder. The connection port and the immersion cylinder are arranged vertically. The fixed ring electromagnet is energized to generate magnetism. The fixed ring electromagnet and the sliding ring magnet are arranged with the same poles. The fixed ring electromagnet is fixed on the inner bottom wall of the passivation cylinder and pushes the sliding ring magnet through repulsion. The sliding ring magnet drives the sliding plate to slide upward 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 connection port. The steering motor drives the locking plate to rotate through the power end. The locking plate rotates away from the opening of the immersion cylinder, and passivation liquid is injected into the immersion cylinder. The passivation liquid occupies half of the space inside the immersion cylinder.

[0009] Preferably, the rotary-sealing type immersion mechanism includes a wheel disc, a clamping bracket and a fixing bolt. The wheel disc is arranged on the inner wall of the connection port, and the wheel disc is threadedly connected to the connection port. The clamping bracket is arranged on the bottom wall of the wheel disc. The fixing bolt is arranged at one end of the clamping bracket away from the wheel disc, and the fixing bolt is threadedly connected to the clamping bracket.

[0010] During use, the robot shaft component is fixed inside the clamping bracket. Rotate the fixing bolt. The fixing bolt moves away from the clamping bracket, and the distance between the fixing bolt and the top wall of the clamping bracket increases. Place the robot shaft component between the fixing bolt and the top wall of the clamping bracket. Rotate the fixing bolt. The fixing bolt moves closer to the clamping bracket, and the fixing bolt fixes the robot shaft component on the clamping bracket. The wheel disc drives the robot shaft component through the connection port and places it inside the soaking cylinder by means of the clamping bracket. The wheel disc is screwed into the connection port to fix the robot shaft component inside the soaking cylinder. The robot shaft component and the clamping bracket occupy the space inside the soaking cylinder, causing the liquid level of the passivation liquid inside the soaking cylinder to rise, thereby being able to completely immerse the robot shaft component.

[0011] Specifically, the heat treatment mechanism includes a heating cylinder, a heat-conducting copper rod, a radiation copper plate, a metal rod, and a heating coil. A plurality of groups of the heating cylinders are provided on the side wall of the passivation cylinder. A plurality of groups of the radiation copper plates penetrate and are provided on one side of the passivation cylinder close to the heating cylinder. The heat-conducting copper rod penetrates the heating cylinder and is provided on the side wall of the radiation copper plate. The metal rod is provided inside the heating cylinder. The heating coil is provided on the inner wall of the heating cylinder outside the metal rod.

[0012] During use, after the soaking and passivation treatment of the robot shaft component is completed, the direction of the current flowing into the fixed annular electromagnet is changed, causing the magnetic poles of the fixed annular electromagnet to change. The fixed annular electromagnet and the sliding annular magnet are arranged with opposite poles. With the weight of the weight ball added, the sliding plate slides down along the inner wall of the passivation cylinder by using the elastic deformation of the lifting spring. As the sliding plate descends, the air inside the passivation cylinder is discharged through the outlet. The sliding plate drives the soaking cylinder to extend out of the inside of the passivation cylinder, and the soaking cylinder moves away from the robot shaft component. The robot shaft component is exposed inside the passivation cylinder. At this time, the pressure inside the passivation cylinder above the sliding plate decreases, and the sliding plate drives the weight ball to extend out of the inside of the passivation cylinder through the outlet to dry the robot shaft component 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 residual passivation liquid on the surface of the robot shaft component is dried. The passivation liquid on the surface of the robot shaft component evaporates into water vapor and remains in the negative-pressure space of the passivation cylinder, preventing the harmful water vapor from evaporating from leaking to the outside of the passivation cylinder and ensuring the safety of the operators. When the robot shaft component is completely exposed inside the passivation cylinder, the current flowing into the fixed annular electromagnet no longer changes, and the magnetic field strength between the fixed annular electromagnet and the sliding annular magnet remains unchanged. The sliding plate stops descending. Since the space inside the passivation cylinder above the sliding plate is in a negative-pressure state, the liquid level of the passivation liquid inside the soaking cylinder rises. The passivation liquid inside the soaking cylinder is in a semi-aqueous state, so that the passivation liquid will not overflow from the inside of the soaking cylinder. The steering motor drives the locking plate to rotate through the power end, and the locking plate seals the opening of the soaking cylinder. Subsequently, 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 rises. After the drying of the robot shaft component is completed, the steam extraction pump pumps 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 has reset to the air pressure value when no water vapor is generated, the steam extraction pump stops the steam extraction operation on the inside of the passivation cylinder, and the drying of the passivated robot shaft component is completed.

[0013] The beneficial effects achieved by the present solution with the above structure are as follows:

[0014] Compared with the prior art, the present solution adopts a sliding passivation treatment method. Through the set drop-down liquid-carrying mechanism, rotary-sealing immersion mechanism, and heat treatment mechanism, and with the coordinated use of the sliding mechanism, steering mechanism, drop-down mechanism, weight-increasing mechanism, and exhaust mechanism, it can prevent harmful gases released by chemical reactions in the passivation liquid from leaking to the outside during the passivation treatment of the robot shaft components, and can dry the robot shaft components after passivation treatment. On the one hand, it removes the residual moisture on the surface of the components, prevents the moisture from affecting the formation of the passivation film, and ensures that the passivation film can uniformly and densely cover the metal surface. On the other hand, it can avoid the passivation liquid from spilling into the external environment, ensuring 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, the probability of the active water vapor diffusing to the outside after heating can be effectively reduced, thereby improving the passivation efficiency of the robot shaft components to a certain extent. To dry the robot shaft components exposed inside the passivation cylinder, 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, it dries the residual passivation liquid on the surface of the robot shaft components. 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, avoiding the leakage of the evaporated harmful water vapor to the outside of the passivation cylinder.

A plurality of groups of the heating cylinders 28 are arranged on the side wall of the passivation cylinder 1.

The metal rod 31 is arranged inside the heating cylinder 28. The heating coil 32 is arranged on the inner wall of the heating cylinder 28 outside the metal rod 31.

[0034] During specific use, in the initial state, the lifting spring 5 is in an extended state. The soaking cylinder 33 is located inside the passivation cylinder 1. The connection port 23 and the soaking cylinder 33 are vertically arranged. The fixed annular electromagnet 13 is energized to generate magnetism. The fixed annular electromagnet 13 and the sliding annular magnet 12 are arranged with the same poles. The fixed annular electromagnet 13 is fixed on the bottom inner wall of the passivation cylinder 1 and pushes the sliding annular magnet 12 through repulsion. The sliding annular magnet 12 drives the sliding plate 4 to slide and rise through the motor box 8. The sliding plate 4 drives the locking plate 10 to fit with the top wall of the passivation cylinder 1. The air inside the passivation cylinder 1 is pushed out by the sliding plate 4 through the connection port 23. The steering motor 9 drives the locking plate 10 to rotate through the power end. The locking plate 10 rotates away from the opening of the soaking cylinder 33, and a passivation liquid is injected into the soaking cylinder 33. The passivation liquid occupies half of the space inside the soaking cylinder 33.

[0035] Fix the robot shaft component inside the clamping bracket 25. Rotate the fixing bolt 26. The fixing bolt 26 moves away from the clamping bracket 25, and the distance between the fixing bolt 26 and the top wall of the clamping bracket 25 increases. Place the robot shaft component between the fixing bolt 26 and the top wall of the clamping bracket 25. Rotate the fixing bolt 26. The fixing bolt 26 approaches the clamping bracket 25, and the fixing bolt 26 fixes the robot shaft component on the clamping bracket 25. The wheel disc 24 drives the robot shaft component through the clamping bracket 25, passes through the connection port 23 and is placed inside the soaking cylinder 33. The wheel disc 24 is screwed into the connection port 23 to fix the robot shaft component inside the soaking cylinder 33. The robot shaft component and the clamping bracket 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.

[0036] After the soaking and passivation treatment of the robot shaft component is completed, the direction of the current flowing into the fixed annular electromagnet 13 is changed, so that the magnetic poles of the fixed annular electromagnet 13 are changed. The fixed annular electromagnet 13 and the sliding annular magnet 12 are arranged with opposite poles. With the weight of the weight ball 15 added, the sliding plate 4 slides down along the inner wall of the passivation cylinder 1 by 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 outlet 16. The sliding plate 4 drives the soaking cylinder 33 to extend out of the inside of the passivation cylinder 1, and the soaking cylinder 33 moves away from the robot shaft component. The robot shaft component is exposed inside the passivation cylinder 1. At this time, the pressure inside the passivation cylinder 1 above the sliding plate 4 decreases, and the sliding plate 4 drives the weight ball 15 to extend out of the inside of the passivation cylinder 1 through the outlet 16;

[0037] Dry the robot shaft component exposed inside the passivation cylinder 1. The heating coil 32 is energized to heat the metal rod 31, and the temperature inside the heating cylinder 28 rises. The heating cylinder 28 conducts the temperature to the inside of the radiation copper plate 30 through the heat-conducting copper rod 29. The radiation copper plate 30 heats the negative-pressure space inside the passivation cylinder 1. After the temperature inside the passivation cylinder 1 rises, the residual passivation liquid on the surface of the robot shaft component is dried. The passivation liquid on the surface of the robot shaft component evaporates into water vapor and remains in the negative-pressure space of the passivation cylinder 1, preventing the harmful water vapor from evaporating from leaking to the outside of the passivation cylinder 1 and ensuring the safety of the operating personnel. When the robot shaft component is completely exposed inside the passivation cylinder 1, the current flowing into the fixed annular electromagnet 13 no longer changes, and the magnetic field strength between the fixed annular electromagnet 13 and the sliding annular magnet 12 remains unchanged. The sliding plate 4 stops descending. Since the space inside the passivation cylinder 1 above the sliding plate 4 is in a negative-pressure state, the liquid level height of the passivation liquid inside the soaking cylinder 33 rises. The passivation liquid inside the soaking cylinder 33 is in a semi-aqueous state, so that the passivation liquid will not overflow from the inside of the soaking cylinder 33;

[0038] The steering motor 9 starts to work. The steering motor 9 drives the locking plate 10 to rotate through the power end. The locking plate 10 seals the opening of the soaking cylinder 33. Subsequently, the pressure sensor 21 monitors the air pressure inside the passivation cylinder 1 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 1 above the sliding plate 4 gradually rises. After the drying of the robot shaft component is completed, the steam extraction pump 19 pumps the harmful water vapor inside the passivation cylinder 1 into the activated carbon adsorption cylinder 18 through the steam extraction pipe 20 for purification, and the water vapor purified by the activated carbon adsorption cylinder 18 is discharged. When the pressure sensor 21 monitors that the air pressure inside the passivation cylinder 1 returns to the air pressure value when no water vapor is generated, the steam extraction pump 19 stops the steam extraction operation inside the passivation cylinder 1, and the drying of the passivated robot shaft component is completed. Just repeat the above operations when using it next time.
