Description

Technical Field

[0001] This application relates to the field of metal processing technology, and more specifically, to a liquid immersion robot for bearing outer surface treatment. Background Technology

[0002] Blackening of metal parts is a key surface anti-corrosion process. Its core lies in forming a dense oxide film on the metal surface through chemical methods, thereby preventing air from contacting the substrate and achieving rust prevention. The typical process includes degreasing, pickling, oxidation, and saponification, among which immersion is the key step in forming a uniform oxide layer.

[0003] Traditional bearing immersion processes have quality defects. Bubbles are easily generated during immersion, which hinders the solution from fully contacting the surface of the parts, thus affecting the immersion effect. Alternatively, stacking is used to improve immersion efficiency, but this can block the solution from reaching the parts. Furthermore, the parts are prone to collisions, which can damage the formed coating and affect the uniformity of the reaction. In addition, most existing immersion methods rely on manual hooking, which can lead to untimely discharge. Moreover, the chemical solutions used for immersion are toxic, and prolonged exposure can harm the health of workers.

[0004] Therefore, there is an urgent need for a highly efficient and flexible immersion robot structure to achieve simultaneous immersion treatment of multiple bearings and improve the immersion efficiency of bearings. Summary of the Invention

[0050] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0052] The following reference Figures 1 to 12 This application describes a liquid-immersion manipulator for bearing outer surface treatment provided according to some embodiments.

[0053] like Figure 1-12 As shown, the immersion robot for bearing outer surface treatment provided according to some embodiments of this application includes a robotic arm assembly 1, a mounting assembly 2, a support assembly 3, a transposition assembly 4, a positioning assembly 5, a docking assembly 6, and a bearing 7. The mounting assembly 2 is rotatably connected to the end of the robotic arm assembly 1. The mounting assembly 2 includes: a mounting cylinder 23 for supporting and fixing the bearing 7; a support assembly 3 disposed inside the mounting assembly 2 and rotatably connected to it; multiple transposition assemblies 4 disposed on the mounting cylinder 23 for fixing the bearing 7; a positioning assembly 5 disposed on the mounting cylinder 23; and multiple docking assemblies 6 disposed on the robotic arm assembly 1 for connecting and fixing the mounting assembly 2 and the support assembly 3.

[0054] It should be noted that the robotic arm assembly 1 serves as the supporting structure for the entire robotic arm, giving it high flexibility; the mounting assembly 2 and the support assembly 3 are movably connected, and the docking assembly 6 is used to adjust the mounting assembly 2 and the support assembly 3 between their movable and fixed states; the positioning assembly 5 is used to precisely reset the position between the mounting assembly 2 and the support assembly 3, improving the accuracy of subsequent processing; the main function of the transposition assembly 4 is to fix the bearing 7.

[0055] During the immersion operation of the bearing outer surface treatment robot, the bearing 7 to be immersed is fixed by the transposition component 4. The robot arm component 1 controls the movement of the mounting cylinder 23 to enter the immersion solution and rotates it to make the bearing 7 evenly immersed in the solution. After immersion is completed, the positioning component 5 makes the mounting component 2 and the support component 3 return to their initial positions, thereby controlling the docking component 6 to fix the mounting component 2 and the support component 3 together. At the same time, the robot arm component 1 controls the mounting component 2 and the support component 3 to drive the bearing 7 to rotate, realizing the centrifugal dehydration treatment of the bearing 7 and preventing the residual solution from the previous solution from entering the next immersion solution and causing mixing.

[0056] In some possible embodiments, such as Figure 1 As shown, the robotic arm assembly 1 includes: a base 11; a rotating seat 12 disposed on the base 11; a first robotic arm 13 rotatably connected to the rotating seat 12; a second robotic arm 14 rotatably connected to the first robotic arm 13; a third robotic arm 15 rotatably connected to the second robotic arm 14; a fourth robotic arm 16 rotatably connected to the third robotic arm 15; and a rotation motor 17 disposed at the end of the fourth robotic arm 16.

[0057] In this embodiment, the base 11 serves as the supporting foundation for the entire robotic arm assembly 1 to ensure the stability of the robotic arm during operation; the rotating base 12 provides a rotational foundation for the first robotic arm 13, the second robotic arm 14, the third robotic arm 15, and the fourth robotic arm 16, and the robotic arms can swing within a certain range, enabling the end effector of the robotic arm assembly 1 to perform more precise movements; the rotating motor 17 is located at the end of the fourth robotic arm 16 and is used to drive the robotic arm assembly to perform various rotational movements, enabling the robotic arm assembly 1 to perform precise movements.

[0058] In some possible embodiments, such as Figure 2-5 As shown, the mounting assembly 2 includes: a hanger 22, which is fixedly connected to the mounting cylinder 23; a central column 21, which is movably engaged inside the hanger 22; and multiple docking columns 24, which are disposed between the hanger 22 and the rotating motor 17.

[0059] In this embodiment, such as Figure 12As shown, the hanger 22 serves as the main support structure to support the dynamic loads that may be generated by the entire mounting assembly 2; the mounting cylinder 23 is fixedly connected to the hanger 22 by bolts to ensure the connection is firm; the central column 21 engages and moves inside the hanger 22, and the connection state between them can be adjusted; the docking column 24 connects the hanger 22 and the rotating motor 17, and plays the role of transmitting power and realizing the relative movement between the two. The number of docking columns 24 is designed according to actual needs to ensure that the rotating motor 17 can stably and efficiently drive the hanger 22 and the mounting cylinder 23.

[0060] In some possible embodiments, such as Figure 3 As shown, the mounting component 2 also includes a plurality of guide strips 2301, which are disposed outside the mounting cylinder 23.

[0061] In this embodiment, multiple guide strips 2301 are arranged outside the mounting cylinder 23. That is, when the mounting cylinder 23 rotates in the solution, the guide strips 2301 outside it move accordingly, and the guide strips 2301 will have a certain disturbance effect on the surrounding solution.

[0062] In some possible embodiments, such as Figure 2 , Figure 4 As shown, the support assembly 3 includes: a connecting frame 31, which is fixedly connected to the central column 21; a connecting plate 32, which is fixedly connected to the connecting frame 31; multiple support feet 33, which are fixedly connected to the connecting plate 32; an upper sealing cover 34, which is fixed to the outside of the connecting frame 31 and rotatably connected to the mounting cylinder 23; and a lower sealing cover 35, which is fixedly connected to the connecting plate 32 and rotatably connected to the mounting cylinder 23. The upper sealing cover 34 and the lower sealing cover 35 are disposed on the top cover and bottom cover of the mounting cylinder 23, respectively.

[0063] In this embodiment, the connecting frame 31 is fixed to the bottom end of the central column 21, which serves as the central support point of the entire support assembly 3. The connecting plate 32 connects the connecting frame 31 and the support foot 33 together and serves as the support base for the upper sealing cover 34 and the lower sealing cover 35. The support foot 33 is the bottom support structure of the support assembly 3 and is magnetic. Since most solution containers are made of metal, the magnetic support foot 33 contacts the container, improving the stability of the device during operation. The upper sealing cover 34 and the lower sealing cover 35 can rotate flexibly within the mounting cylinder 23.

[0064] In some possible embodiments, such as Figure 6 , Figure 7As shown, the transposition assembly 4 includes: multiple rotating frames 41, which are mounted on the mounting cylinder 23; a secondary bevel gear 42, which is fixedly connected to the rotating frames 41; two rotating hooks 43, which are fixedly mounted at both ends of the rotating frames 41; a limiting hook 44, which is mounted on the mounting cylinder 23 and has a space between it and the rotating hooks 43; and a main bevel gear 45, which is fixedly mounted on the connecting frame 31 and meshes with the secondary bevel gear 42.

[0065] In this embodiment, multiple rotating frames 41 are installed outside the mounting cylinder 23. The secondary bevel gear 42 is fixedly connected to the rotating frame 41 and is used to transmit power to realize the rotation of the rotating frame 41. The rotating hook 43 and the limiting hook 44 are used to fix the bearing 7, and there is a certain space between the rotating hook 43 and the limiting hook 44. This space allows the rotating hook 43 to pick up and put down the bearing 7 during rotation. The main bevel gear 45 is installed inside the mounting cylinder 23, and the secondary bevel gear 42 passes through the mounting cylinder 23 and meshes with the main bevel gear 45. During the immersion process, the mounting cylinder 23 is driven to rotate, and the main bevel gear 45 is stationary. Thus, the secondary bevel gear 42 rotates with the mounting cylinder 23 and moves along the inside of the main bevel gear 45. The secondary bevel gear 42 will rotate, and the rotating hook 43 will rotate accordingly, making the bearing 7 dynamic. This helps to eliminate air bubbles in the bearing 7 during the immersion process, thereby improving the immersion effect of the bearing 7.

[0066] In some possible embodiments, such as Figure 8 As shown, the positioning component 5 includes: a first positioning sensor 51, which is disposed on the upper sealing cover 34; and a second positioning sensor 52, which is disposed on the mounting cylinder 23; the first positioning sensor 51 and the second positioning sensor 52 work together.

[0067] In this embodiment, the first positioning sensor 51 is used to sense the position of the upper sealing cover 34, enabling it to capture the displacement or rotation dynamics of the upper sealing cover 34. By docking the first positioning sensor 51 with the second positioning sensor 52, the upper sealing cover 34 is restored to its initial position inside the mounting cylinder 23, thereby causing the external rotating hook 43 of the mounting cylinder 23 to return to its initial position, improving the positioning accuracy.

[0068] In some possible embodiments, such as Figure 9-10 As shown, the docking assembly 6 includes: a sealing seat 61, disposed outside the rotating motor 17; an air inlet pipe 6101, disposed on the sealing seat 61; a piston pipe 62, disposed inside the sealing seat 61; and a piston column 63, connected to the piston pipe 62.

[0069] In this embodiment, the air inlet pipe 6101 serves as an interface for connecting to an external air source; the piston pipe 62 provides a sliding track for the piston rod 63, and the piston rod 63 can reciprocate within it by controlling the gas input.

[0070] In some possible embodiments, such as Figure 9 , Figure 11 As shown, the docking assembly 6 also includes: a docking block 64, which is fixedly connected to the piston tube 62; a docking protrusion 65, which is fixedly disposed outside the central column 21; and the docking block 64 engages with the outside of the docking protrusion 65.

[0071] In this embodiment, the docking block 64 is fixed to the end of the piston column 63, and the docking protrusion 65 is disposed on the central column 21. The docking block 64 is driven to move by the piston column 63, so that multiple docking blocks 64 and docking protrusion 65 contact and engage, thereby fixing the central column 21. This method can quickly separate or connect the central column 21.

[0072] In some possible embodiments, such as Figure 7 , Figure 8 As shown, the bearing 7 is mounted on the rotating hook 43, between it and the limiting hook 44.

[0073] In this embodiment, the bearing 7 is placed on the corresponding rotating hook 43, and multiple rotating hooks 43 are evenly arranged on the outside of the mounting cylinder 23. That is, the mounting cylinder 23 can perform liquid immersion treatment on multiple bearings 7 in one batch at the same time. Compared with processing the bearings 7 one by one, this batch processing method significantly improves the liquid immersion efficiency, reduces the processing time, and thus improves the overall processing efficiency.

[0074] During the immersion operation of the bearing outer surface treatment robot, the rotating hook 43 is rotated to a horizontal position, increasing the space between the rotating hook 43 and the limiting hook 44. This allows the bearing 7 to be immersed to be placed on the rotating hook 43. The robot arm assembly 1, through a multi-stage rotating structure, namely the rotating seat 12, the first robot arm 13, the second robot arm 14, the third robot arm 15, and the fourth robot arm 16, adjusts its position so that the mounting cylinder 23 enters the immersion solution. The magnetic support foot 33 then contacts the bottom of the solution container and is fixed, thereby activating the rotating motor 17, which drives the mounting cylinder 23 to rotate in the solution. Due to the setting of the guide strip 2301, it can disturb the surrounding solution, helping the bearing 7 to be immersed evenly. The secondary bevel gear... As the mounting cylinder 23 rotates, the rotating hook 43 and the bearing 7 rotate, achieving uniform immersion. After immersion, the first positioning sensor 51 and the second positioning sensor 52 dock, making the rotating hook 43 vertical and reducing the space between it and the limiting hook 44. Thus, the robotic arm assembly 1 controls the mounting cylinder 23 to rise above the immersion solution. Then, the piston tube 62 inputs gas, causing the piston column 63 to drive the docking block 64 to move and engage with the docking protrusion 65, thereby fixing the central column 21 and the main bevel gear 45. Then, the rotating motor 17 rotates, generating centrifugal force to dehydrate the bearing 7, preventing residual solution from entering the next immersion solution and causing mixing, thus achieving efficient treatment of the bearing 7.
