Description

Technical Field

[0001] This utility model relates to the field of rare earth processing technology, and in particular to a tool library for rare earth electrolysis discharge. Background Technology

[0002] With the development of science and technology, rare earth elements play an irreplaceable role in new energy, electronic information, aerospace and other fields due to their unique physicochemical properties. In rare earth processing (such as rare earth oxide roasting, rare earth metal smelting, rare earth salt crystallization, etc.), materials usually need to be temporarily stored in reaction kettles, smelting furnaces or storage tanks before being discharged and transported to the next process. Rare earth electrolysis discharge robots are the core execution equipment in the discharge process. Their end effector needs to switch between various special tools (such as shell-breaking hammers, slag scoops, eye pluggers, temperature probes, cleaning brushes, etc.) according to different working conditions (such as normal discharge, abnormal handling, equipment maintenance, etc.).

[0003] Currently, specialized tools used in the rare earth electrolysis process are typically piled up on the ground or temporary supports around the rare earth electrolysis output robot. When switching specialized tools, the rare earth electrolysis output robot needs to grasp them through visual positioning or manual guidance. This results in problems such as poor positioning accuracy, easy deviation during robot grasping (deviation > 5mm), long time consumption for picking and placing (about 5-10 minutes for a single tool change), and easy collision damage to tools. As a result, the operational flexibility and continuity of the rare earth electrolysis output robot are severely limited. This is especially true in large rare earth electrolysis workshops (single series capacity exceeds 1,000 tons / year, and the robot operates more than 300 times per day), where the need for frequent tool switching is even more urgent. There is an urgent need for a tool library that can achieve rapid and accurate storage and retrieval of tools. Utility Model Content

[0004] The purpose of this utility model is to provide a tool library for rare earth electrolysis material discharge, so as to alleviate the technical problems in the prior art where special tools used in the rare earth electrolysis material discharge process are usually piled on the ground or temporary supports around the rare earth electrolysis material discharge robot. When switching special tools, the rare earth electrolysis material discharge robot needs to grasp them through visual positioning or manual guidance. This has problems such as poor positioning accuracy, easy deviation of the robot during grasping, long time for picking and placing, and easy collision damage to tools, which seriously limit the operational flexibility and continuity of the rare earth electrolysis material discharge robot.

[0005] In the first aspect, this utility model provides a tool library for rare earth electrolysis discharge, including a storage rack, a positioning component and an identification component; The storage rack is set in a robot coordinate system constructed based on the rare earth electrolysis discharge robot. The storage rack has multiple storage positions, and each storage position is equipped with the positioning component. The positioning component is used to detachably connect with the special tool for rare earth electrolysis discharge so as to position the special tool on the storage position. The identification component is installed on the storage rack. The identification component is used to identify the target special tool according to the instructions of the rare earth electrolysis discharge robot and determine the position of the target special tool on the storage rack.

[0006] In an optional embodiment, the positioning component includes a pneumatic gripper for gripping the handle of the special tool.

[0007] In an optional embodiment, the positioning component has multiple pneumatic grippers, and the multiple pneumatic grippers in the positioning component are distributed at vertical intervals.

[0008] In an optional embodiment, the inner side of the pneumatic gripper is provided with a guide groove extending vertically, the guide groove being used to accommodate the handle of a special tool held by the pneumatic gripper.

[0009] In an optional implementation, a docking assembly is also included, which is mounted on the handle of a special tool for connection to the rare earth electrolysis discharge robot.

[0010] In an optional embodiment, the docking assembly includes a connecting pipe and a limiting block, the connecting pipe being sleeved over the handle of the special tool, and the limiting block being fixed to the top opening of the connecting pipe.

[0011] In an optional implementation, the identification component includes an identification tag and a reader / writer. Each positioning component is provided with the identification tag, and the reader / writer is installed inside the storage rack to identify the identification tag on the positioning component where the target special tool is located according to the grasping command issued by the rare earth electrolysis discharge robot, so as to determine the storage location of the target special tool.

[0012] In an optional embodiment, the identification component further includes a position detection element installed inside the storage rack for detecting the distance between its location and the target tool.

[0013] In an optional embodiment, the storage rack includes a frame and a back support plate. The frame includes a front facade and a back facade that are positioned opposite each other. A notch is provided between the top and bottom of the front facade of the frame for the special tool to enter and exit. The back support plate is fixed to the back facade of the frame, and the positioning component is installed on the side of the back support plate facing the notch.

[0014] In an optional embodiment, the storage rack further includes a side support plate, which is installed on the side facade of the frame located between the front facade and the rear facade. The side support plate and the back support plate are both made of high-temperature resistant engineering plastic, and the frame is made of stainless steel.

[0015] This utility model provides a tool library for rare earth electrolysis discharge, comprising a storage rack, a positioning component, and an identification component. The storage rack is positioned within a robot coordinate system based on a rare earth electrolysis discharge robot. The rack has multiple storage slots, each equipped with a positioning component. The positioning component is detachably connected to a special tool for rare earth electrolysis discharge to position the tool at the storage slot. The identification component is mounted on the storage rack and identifies the target special tool according to instructions from the rare earth electrolysis discharge robot, determining its position on the rack. This tool library stores various special tools for rare earth electrolysis discharge. These tools work in conjunction with the rare earth electrolysis discharge robot to handle different operating conditions during rare earth electrolysis discharge. Typically, these special tools include shell-breaking hammers, slag-removing spoons, eye-plugging devices, temperature probes, and cleaning brushes. In rare earth processing, to facilitate control of the movement path of the rare earth electrolysis discharge robot, a robot coordinate system is usually constructed based on the rare earth electrolysis discharge robot. Therefore, this utility model sets the storage rack in the robot coordinate system, so that the position of the storage rack corresponds to the position of the rare earth electrolysis discharge robot. When the rare earth electrolysis discharge robot needs to switch to a special tool, the current position of the rare earth electrolysis discharge robot in the robot coordinate system and the current position of the storage rack in the rare earth electrolysis discharge robot coordinate system can be obtained first. Then, the movement path of the rare earth electrolysis discharge robot can be planned according to the current position of the rare earth electrolysis discharge robot and the current position of the storage rack, so that the rare earth electrolysis discharge robot can reach one side of the storage rack after walking along the movement path. Subsequently, based on the special tool that the rare earth electrolysis discharge robot needs to switch to (i.e., the target special tool), the corresponding grasping command is sent to the identification component. At this time, the identification component can identify the specific position of the target special tool on the storage rack according to the received command. Then, the rare earth electrolysis discharge robot plans the required movement distance of its end effector based on the positional relationship between its current position and the storage rack, and the identification result of the identification component. Then, it moves to the target special tool according to the planned movement distance and grasps the target tool. Since the positioning component and the special tool are detachably connected, after the rare earth electrolysis discharge robot grasps the target special tool, the positioning component at the target special tool can also be separated from the target special tool to prevent obstruction of the grasping process of the rare earth electrolysis discharge robot.

[0016] Compared with existing technologies, the tool library for rare earth electrolysis discharge provided by this utility model places the storage rack in the robot coordinate system and uses a recognition component to determine the position of the target special tool on the storage rack. This allows the rare earth electrolysis discharge robot to accurately move to one side of the storage rack and accurately grasp the target special tool on the storage rack without the need for visual positioning or manual guidance. This makes the grasping process more precise. At the same time, due to the improved grasping accuracy, the grasping action of the rare earth electrolysis discharge robot does not need to be corrected multiple times, and the grasping efficiency can also be effectively improved. This allows the rare earth electrolysis discharge robot to quickly and accurately store and retrieve special tools on the storage rack, effectively improving the operational flexibility and continuity of the rare earth electrolysis discharge robot, and meeting the needs of large rare earth electrolysis workshops for frequent switching of special tools.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Example: like Figure 1 and Figure 2 As shown, the rare earth electrolysis discharge tool library provided in this embodiment includes a storage rack 1, a positioning component 2, and an identification component 3. The storage rack 1 is set in a robot coordinate system constructed with the rare earth electrolysis discharge robot as the reference. The storage rack 1 has multiple storage positions, and each storage position is equipped with a positioning component 2. The positioning component 2 is used to detachably connect with the special tool 4 for rare earth electrolysis discharge to position the special tool 4 in the storage position. The identification component 3 is installed on the storage rack 1. The identification component 3 is used to identify the target special tool according to the instructions of the rare earth electrolysis discharge robot and determine the position of the target special tool on the storage rack 1.

[0024] The rare earth electrolysis discharge tool library provided in this embodiment is used to store a variety of rare earth electrolysis discharge special tools 4. The rare earth electrolysis discharge special tools 4 are used to cooperate with the rare earth electrolysis discharge robot to handle different working conditions during rare earth electrolysis discharge. Based on this, the special tools 4 are usually tools such as shell-breaking hammers, slag-removing spoons, eye pluggers, temperature probes, cleaning brushes, and rare earth metal clamps.

[0025] It should be noted that, Figure 1Only the slag-removing spoon (4) is shown. Since the storage rack 1 has multiple storage positions, there is no limit to the number and specific types of special tools 4 on the storage rack 1, and they can be selected according to the actual working conditions. For example, the storage rack 1 has no fewer than six storage positions, and each storage position is equipped with a special tool 4 (such as a shell-breaking hammer, slag-removing spoon, eye plugger, temperature probe, cleaning brush, rare earth metal holder). In this case, the special tools 4 on the storage rack 1 can meet the usage requirements of the entire process of rare earth electrolysis discharge (discharge, slag removal, eye plugging, temperature measurement, and cleaning), effectively improving the compatibility of this rare earth electrolysis discharge tool library with various special tools 4.

[0026] In order to facilitate the control of the movement path of the rare earth electrolysis discharge robot during rare earth processing, a robot coordinate system is usually constructed based on the rare earth electrolysis discharge robot. Therefore, in this embodiment, by setting the storage rack 1 in the robot coordinate system, the position of the storage rack 1 can be correlated with the position of the rare earth electrolysis discharge robot. When the rare earth electrolysis discharge robot needs to switch to the special tool 4, the current position of the rare earth electrolysis discharge robot in the robot coordinate system and the current position of the storage rack 1 in the rare earth electrolysis discharge robot coordinate system can be obtained first. Then, the movement path of the rare earth electrolysis discharge robot can be planned according to the current position of the rare earth electrolysis discharge robot and the current position of the storage rack 1, so that the rare earth electrolysis discharge robot can reach one side of the storage rack 1 after walking along the movement path. Then, according to the special tool 4 (i.e. the target special tool) that the rare earth electrolysis discharge robot needs to switch to, the corresponding grasping command is sent to the identification component 3. At this time, the identification component 3 can identify the specific position of the target special tool on the storage rack 1 according to the command it receives. Then, the rare earth electrolysis discharge robot plans the required moving distance of the end of the rare earth electrolysis discharge robot according to the positional relationship between its current position and the storage rack 1 and the identification result of the identification component 3. Then, it moves to the target special tool according to the planned moving distance and grasps the target tool.

[0027] Since the positioning component 2 and the special tool 4 are detachably connected, after the rare earth electrolysis discharge robot grabs the target special tool, the positioning component 2 at the target special tool can also be separated from the target special tool to prevent obstruction to the grabbing process of the rare earth electrolysis discharge robot.

[0028] Compared with the prior art, the rare earth electrolysis discharge tool library provided in this embodiment places the storage rack 1 in the robot coordinate system and, together with the recognition component 3, determines the position of the target special tool on the storage rack 1. This allows the rare earth electrolysis discharge robot to accurately move to one side of the storage rack 1 and accurately grasp the target special tool on the storage rack 1 without the need for visual positioning or manual guidance. This makes the grasping process more precise (the grasping success rate under the existing visual positioning method is usually 90%, while the grasping success rate of the rare earth electrolysis discharge tool library provided in this embodiment when combined with the rare earth electrolysis discharge robot is usually 99.8%). At the same time, due to the improved grasping accuracy, the grasping action of the rare earth electrolysis discharge robot does not need to be corrected multiple times, and the grasping efficiency can also be effectively improved. This allows the rare earth electrolysis discharge robot to quickly and accurately store and retrieve the special tool 4 on the storage rack 1, effectively improving the operational flexibility and continuity of the rare earth electrolysis discharge robot and meeting the needs of large rare earth electrolysis workshops for frequent switching of special tools 4.

[0029] It should be noted that, in order to prevent the tool library for rare earth electrolysis from being corroded by the electrolytic cell and to improve the gripping efficiency of the special tool 4, in this embodiment, the storage rack 1 is preferably set in a position in the electrolysis workshop that is far away from the electrolytic cell but close to the working area of ​​the rare earth electrolysis discharge robot. Specifically, the distance between the storage rack 1 and the edge of the electrolytic cell is ≥2m.

[0030] It should also be noted that each storage position on the storage rack 1 in this embodiment uses a positioning component 2 to fix the special tool 4. Therefore, each storage position is designed independently and the special tool 4 can be disassembled and replaced individually. Even if a storage position is damaged, it will not affect the storage and retrieval process of other special tools 4, which effectively reduces the operation and maintenance cost of the tool library for rare earth electrolysis output.

[0031] like Figure 3 and Figure 4 As shown, the positioning component 2 includes a pneumatic gripper 20, which is used to grip the handle 40 of the special tool 4.

[0032] To facilitate the use and gripping of various special tools 4, special tools 4 are usually equipped with handles 40. Based on this, the positioning component 2 provided in this embodiment can adopt a pneumatic gripper 20. By using the pneumatic gripper 20 to hold the special tool 4, not only can the stability of the special tool 4 in the storage position be guaranteed, but the key parts of the special tool 4 will not be damaged.

[0033] The pneumatic gripper 20 is driven to open by a cylinder 200 and to close by a return spring. Specifically, the pneumatic gripper 20 may include a cylinder 200 and two symmetrically arranged half-jaws 201. Both half-jaws 201 are hinged to the output end of the cylinder 200. When the cylinder 200 extends, it can drive the two half-jaws 201 to rotate in a relatively far apart direction, thereby realizing the opening process of the gripper.

[0034] It should be noted that there are no restrictions on the specific structure of the positioning component 2, and it can be selected according to actual needs. For example, the positioning structure can also use a clip, positioning pin, or other structures.

[0035] To extend the service life of the pneumatic gripper 20, in this embodiment, the material of the half-jaw 201 in the pneumatic gripper 20 is preferably chromium vanadium alloy steel. Furthermore, the surface of the half-jaw 201 can also be coated with a nickel-plated anti-corrosion layer.

[0036] Furthermore, such as Figure 3 As shown, there are multiple pneumatic grippers 20 in the positioning component 2, and the multiple pneumatic grippers 20 in the positioning component 2 are distributed at intervals along the vertical direction.

[0037] The multiple pneumatic grippers 20 in the positioning component 2 are used to simultaneously grip the handle 40 of the special tool 4. Thus, when the positioning component 2 includes multiple pneumatic grippers 20 distributed vertically at intervals, the multiple pneumatic grippers 20 can cooperate with each other to effectively improve the gripping stability and gripping accuracy of the special tool 4 on the positioning component 2.

[0038] In this embodiment, the clamping force of the pneumatic gripper 20 on the special tool 4 can be adjusted. For example, the clamping force can be adjusted within the range of 5-15N.

[0039] In this embodiment, the inner side of the pneumatic gripper 20 is provided with a guide groove extending vertically, which is used to accommodate the handle 40 of the special tool 4 held by the pneumatic gripper 20.

[0040] The guide groove can not only improve the clamping stability of the positioning component 2 on the special tool 4 and ensure that the special tool 4 does not shake when stored, but also limit the insertion direction of the special tool 4, so that the special tool 4 is inserted vertically downward during the process of inserting into the positioning component 2, which is conducive to accurately judging the position of the special tool 4 on the storage rack 1.

[0041] The guide groove can be 150-200mm deep, and the inner wall of the guide groove can be covered with a polytetrafluoroethylene wear-resistant liner.

[0042] like Figure 2 and Figure 3As shown, in order to improve the installation stability of the positioning component 2, multiple pneumatic grippers 20 in each positioning component 2 can be mounted on the positioning mounting plate 5 through the positioning flange 21, and the positioning mounting plate 5 is fixed on the storage rack 1.

[0043] like Figure 5 As shown, the rare earth electrolysis discharge tool library provided in this embodiment also includes a docking component 6, which is installed on the handle 40 of the special tool 4 and is used to connect with the rare earth electrolysis discharge robot.

[0044] The docking component 6 facilitates a stable connection between the special tool 4 and the rare earth electrolysis discharge robot, thereby improving the robot's gripping stability of the special tool 4.

[0045] In this embodiment, the docking assembly 6 includes a connecting pipe 60 and a limiting block 61. The connecting pipe 60 is sleeved on the handle 40 of the special tool 4, and the limiting block 61 is fixed to the top opening of the connecting pipe 60.

[0046] The connecting pipe 60 not only supports the limiting block 61, but also protects the handle 40 of the special tool 4. The limiting block 61 is used for positioning. The rare earth electrolysis discharge robot can use an infrared sensor to determine the relative position between its gripping position on the special tool 4 and the limiting block 61, thereby determining whether the gripping position has deviated, which helps to improve the stability of the gripping process of the special tool 4.

[0047] Furthermore, the limit stop 61 can be fixed to the top opening of the connecting pipe 60 by screws or other fasteners.

[0048] It should be noted that during the rare earth electrolysis production process, oxide slag (mainly composed of rare earth oxides, electrolyte molten salt, and a small amount of metal particles) will be continuously generated in the electrolytic cell. If this slag is not cleaned in time, it will reduce the purity of the melt and affect the deposition quality and current efficiency of rare earth metals. Traditional slag removal tools are mostly made of ordinary stainless steel (such as 304 stainless steel) or carbon steel. However, under the extreme conditions of high temperature (800-1000℃), strong corrosion (volatile gases such as hydrogen fluoride and chlorine), and high wear (scouring by slag particles), problems such as corrosion perforation, deformation failure, and difficulty in cleaning slag adhesion are prone to occur. Based on this, in order to extend the service life of the special tool 4, this embodiment preferably uses titanium alloy steel for the handle 40 and the spoon head of the slag removal spoon in the special tool 4.

[0049] In this embodiment, the identification component 3 includes an identification tag 30 and a reader / writer. Each positioning component 2 is provided with an identification tag 30. The reader / writer is installed inside the storage rack 1 and is used to identify the identification tag 30 on the positioning component 2 where the target special tool is located according to the grasping command issued by the rare earth electrolysis discharge robot, so as to determine the storage location of the target special tool.

[0050] The identification tag 30 can be an RFID (Radio Frequency Identification) electronic tag. The inner wall of the pneumatic gripper 20 can be provided with an installation groove located on one side of the guide groove. The identification tag 30 is embedded in the inner wall of the installation groove. At the same time, in order to extend the service life of the identification tag 30, the identification tag 30 can also be waterproofed and corrosion-resistant.

[0051] The reader can work in conjunction with the identification tag 30 to automatically identify the type of the target special tool (e.g., distinguishing between a shell-breaking hammer and a slag-removing spoon via RFID coding). The reader can also communicate with the robot control system or the control system of the rare earth electrolysis tool library, sending the identification results to these systems. Specifically, when the reader emits a specific frequency radio frequency signal, the identification tag 30 obtains energy through induced current (passive tag) or actively transmits a signal (active tag), wirelessly transmitting its unique code and additional information (such as tool type, last usage time, maintenance records, etc.) back to the reader. This information is then transmitted to the robot control system or the rare earth electrolysis tool library's control system for analysis and processing. Thus, the rare earth electrolysis tool library can also solve the pain points of traditional special tool management, such as reliance on manual recording, poor positioning accuracy, and lagging status monitoring, achieving intelligent and precise storage and retrieval of special tools and full lifecycle management.

[0052] The reader can be a high-frequency reader. To improve its performance, in this embodiment, the reader is preferably fixed to the inner wall of the storage rack 1, and the communication distance between the reader and the electronic tag is no more than 50mm.

[0053] Furthermore, the identification component 3 also includes a position detection element 31, which is installed inside the storage rack 1 and is used to detect the distance between its location and the target special tool.

[0054] Once the reader and identification tag 30 determine the specific type of the target tool required by the rare earth electrolysis discharge robot, the position detection component 31 is activated to detect the distance between itself and the target tool, thereby accurately determining the position of the target tool on the storage rack 1. At this time, the robot control system or the control system of the rare earth electrolysis discharge tool library can also receive the detection results of the position detection component 31, thereby planning the path for the rare earth electrolysis discharge robot to move to the location of the target tool, and then controlling the rare earth electrolysis discharge robot to move accurately along the path to the location of the target tool to accurately grasp the target tool.

[0055] Taking the slag-removing spoon as an example, the process of switching the slag-removing spoon to the end of the rare earth electrolysis discharge robot is as follows: The rare earth electrolysis discharge robot sends the "switch to slag-removing spoon" command to the control system of the rare earth electrolysis discharge tool library - the control system of the rare earth electrolysis discharge tool library locates the storage position number of the slag-removing spoon through the reader and plans the robot's movement path through the position detection component 31 - the robot moves to one side of the storage rack 1 - grabs the slag-removing spoon (the pneumatic gripper 20 is automatically released), the control unit updates the status of the current storage position to "removed" - the robot performs the slag removal operation.

[0056] Therefore, the rare earth electrolysis discharge tool library provided in this embodiment can also include a control system. The control system includes a control box integrated inside the storage rack 1. This control box can be an explosion-proof enclosure that meets the explosion-proof requirements of the electrolysis workshop. The control system can receive tool request commands (such as "switch to slag scoop") from the rare earth electrolysis discharge robot, query the location of the target special tool through the identification component 3, control the positioning component 2 to clamp or release the target special tool, and guide the robot to accurately grasp the target tool. In addition, the control system can also update the status of the special tool 4 (such as in place / removed / requires maintenance) and monitor the ambient temperature of the storage location to avoid high temperature accelerating corrosion.

[0057] The position detection component 31 can be a laser sensor. Furthermore, such as... Figure 4 As shown, the position detection component 31 can be installed on the support plate 32, and the support plate 32 is fixed to the side wall of the storage rack 1.

[0058] like Figure 1 and Figure 2 As shown, the storage rack 1 includes a frame 10 and a back support plate 11. The frame 10 includes a front facade and a back facade that are opposite each other. A notch is provided between the top and bottom of the front facade of the frame 10 for a special tool 4 to enter and exit. The back support plate 11 is fixed to the back facade of the frame 10, and the positioning component 2 is installed on the side of the back support plate 11 facing the notch.

[0059] The back support plate 11 is fixed to the back facade of the frame 10 and the positioning component 2 is installed on the side of the back support plate 11 facing the notch. This can optimize the position of the positioning component 2 and the path of the special tool 4 entering and exiting the storage rack 1, thereby improving the usability of the tool library for rare earth electrolysis discharge.

[0060] It should be noted that, to facilitate the establishment of the correspondence between the storage rack 1 and the robot coordinate system, this embodiment preferably uses a cuboid shape for the frame 10 (the flatness of the top of the frame 10 is ≤0.08mm), and the top of the frame 10 forms a standardized docking platform that can precisely match the grasping coordinate system of the end effector of the rare earth electrolysis discharge robot (calibrated through 3D modeling, deviation ≤0.3mm). During the grasping of the special tool 4, through this standardized docking platform and precise positioning guidance, the time for the rare earth electrolysis discharge robot to change the special tool 4 once is ≤1 minute (existing technologies typically require 5-15 minutes), thereby effectively supporting efficient continuous operation and reducing production interruptions.

[0061] Furthermore, the storage rack 1 also includes a side support plate 12, which is installed on the side facade of the frame 10 between the front facade and the rear facade; both the side support plate 12 and the rear support plate 11 are made of high-temperature resistant engineering plastic, and the frame 10 is made of stainless steel.

[0062] Among them, the stainless steel can be 316L stainless steel that is resistant to hydrogen fluoride corrosion.

[0063] High-temperature resistant engineering plastics not only withstand the high-temperature environment of the electrolysis workshop but also possess excellent corrosion resistance, thus protecting the rare earth electrolysis tool magazine from the corrosive gases generated during the rare earth electrolysis process and extending its service life. Furthermore, high-temperature resistant engineering plastics also exhibit excellent self-lubrication and a low coefficient of friction, helping to reduce wear on the special tools during storage and retrieval.

[0064] To further improve the service life of the rare earth electrolysis discharge tool library, proximity sensors can be installed on the outside of the storage rack 1, and anti-vibration pads can be covered on the side support plate 12 and the back support plate 11, thereby ensuring operational safety and reducing the impact of environmental vibration on the rare earth electrolysis discharge tool library.

[0065] like Figures 1-2 As shown, the bottom of the frame 10 may also be provided with a foot cup 7 or casters.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
