Description

Technical Field

[0001] This invention relates to the field of neutron target technology, and specifically to a disassembly and assembly mechanism and a target replacement method for disassembling and assembling rotating target assemblies. Background Technology

[0002] The target system is the core component of an ultra-high flux deuterium-tritium fusion neutron source. Its main function is to withstand the bombardment of high-power deuterium ion beams and produce neutrons through the deuterium-tritium fusion reaction. Currently, target systems often tend to use rotating targets. By rotating the target sheet, the temperature of the target sheet can be reduced, avoiding continuous heating.

[0003] Currently, when replacing the target piece of a rotating target, the target system as a whole is usually replaced. This requires replacing the entire target system, which is difficult and relatively uneconomical.

[0004] Furthermore, although existing technologies disclose replacement systems or devices for target systems, they are difficult to apply to the replacement of target plates for rotating targets. This is because, in practical applications, the entire target system is quite heavy, and in order to ensure sufficient clamping force, the replacement structure is often a rigid clamping structure. Since the target plates of rotating targets are often disc-shaped or annular, their structure is thinner and more intricate than that of other flat target plates. Especially for disc-shaped target plates with a large area, if a rigid clamping structure is directly used to grip the target plate, it is easy to cause structural damage to the target plate, whether in the thickness direction or the radial direction of the target plate, leading to breakage or fragments falling off. This could fill the entire environment with radioactive materials, posing a radioactive hazard to the operators when the entire device needs to be maintained.

[0005] In addition, the rotating target plate is usually connected to the rotating shaft to form a rotating target plate assembly, which is then mounted on the rotating shaft. However, existing replacement systems or devices have excessively large clamping parts and uneven clamping, which can easily cause positional deviations in the rotating target plate assembly during installation, leading to installation difficulties or even being difficult to install.

[0006] Therefore, it is necessary to develop a disassembly and replacement mechanism for the rotating target assembly to enable smooth replacement of the rotating target assembly. Summary of the Invention

[0007] The purpose of this invention is to provide a disassembly and assembly mechanism and a target replacement method for disassembling and assembling a rotating target assembly, so as to solve the technical problem that the rotating target is prone to positional deviation during the installation process, and also to solve the technical problem that the rotating target is prone to falling off during the disassembly and assembly process.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] On the one hand, a disassembly and assembly mechanism for disassembling and assembling a rotating target assembly is provided, the rotating target assembly being mounted on a rotating shaft;

[0010] The disassembly and assembly mechanism is provided with a central shaft corresponding to the rotating shaft. The central shaft has the same cross-sectional diameter as the rotating shaft. When disassembling and assembling the rotating target assembly, the end of the central shaft can abut against the opposite end of the rotating shaft, and the center line of the central shaft coincides with the center line of the rotating shaft.

[0011] The disassembly and assembly mechanism is equipped with a transfer component, which can be adsorbed and connected to the rotating target assembly. When the end of the central shaft abuts against the end opposite to the rotating shaft, the transfer component can drive the rotating target assembly to move on the central shaft and the rotating shaft.

[0012] In this solution, during the assembly and disassembly of the target piece, the end of the central shaft abuts against the opposite end of the rotating shaft, and the centerline of the central shaft coincides with the centerline of the rotating shaft. Therefore, by utilizing the principle of concentric shafts, the rotating target piece assembly is assembled and disassembled in a "shaft-to-shaft" manner, and is moved accordingly to the central shaft or rotating shaft. Structurally, this improves the accuracy of the target piece's installation position, increases assembly and disassembly efficiency, solves the technical problem of positional deviation during the installation of the rotating target piece assembly, and also solves the technical problem of the rotating target piece assembly easily falling off during assembly and disassembly.

[0013] As one implementation of the transfer component being able to adsorb and connect with the rotating target component, the transfer component includes a plurality of uniformly distributed suction cup components, each of which can extend and retract in a direction parallel to the extension direction of the central axis; the suction cup component includes a flexible suction cup, which is used to adsorb onto the surface of the rotating target component.

[0014] During the target replacement process, multiple suction cups are used to pick up or move the target piece, which solves the technical problem that the thin and fragile annular target piece may be damaged if the clamping method used in the existing technology is adopted.

[0015] When it is necessary to move the rotating target assembly, each suction cup assembly is first extended so that each flexible suction cup is attached to the surface of the rotating target assembly. Then, when the transfer assembly moves, it can drive the rotating target assembly to move.

[0016] As a preferred embodiment of the suction cup assembly, each of the suction cup assemblies is a vacuum suction cup device, with one end of a vacuum tube connected to each of the flexible suction cups, and the other end of each of the vacuum tubes connected to a vacuum pumping device.

[0017] When it is necessary to move the rotating target assembly, first extend each suction cup assembly and ensure that each suction cup is in contact with the rotating target assembly. Then turn on the vacuum device to create a vacuum between the flexible suction cup and the part in contact with the rotating target assembly, thereby achieving adsorption of the rotating target assembly.

[0018] As one way to achieve the extension and retraction of each suction cup component, a telescopic rod is provided at the end of the flexible suction cup away from the rotating target component. The telescopic rod can drive the flexible suction cup to extend and retract in a direction parallel to the extension direction of the central axis.

[0019] As another way to achieve the extension and retraction of each suction cup component, the disassembly and assembly mechanism is mounted on the support structure via a mounting bracket. A first bracket plate and a second bracket plate are fixed on the mounting bracket. Each suction cup component is mounted on the first bracket plate. A plurality of lead screws are fixed between the first bracket plate and the second bracket plate corresponding to each suction cup component. A lead screw slider is provided at one end of each suction cup component extending out of the first bracket plate. Each lead screw slider is threadedly connected to the corresponding lead screw. A lead screw motor is fixed at one end of each lead screw extending out of the second bracket plate. Each lead screw motor can rotate forward or reverse simultaneously and can drive each lead screw slider to move on the corresponding lead screw.

[0020] When rotating forward, the lead screw slider can move along the corresponding lead screw in a direction away from the lead screw motor, causing the suction cup assembly to extend. When rotating in reverse, the lead screw slider can move along the corresponding lead screw in a direction closer to the lead screw motor, causing the suction cup assembly to retract.

[0021] Preferably, the rotating target assembly includes a rotating target, which is mounted on a rotating shaft via a pressure cap, the pressure cap being fitted around the rotating shaft; the pressure cap has multiple bolt holes, and the rotating target has corresponding through holes at positions corresponding to each bolt hole; bolts are installed in each bolt hole and corresponding through hole to achieve a fixed connection between the rotating target and the pressure cap; a rotating turntable is mounted on the mounting bracket, the rotating turntable having a fixed end and a rotating end, the fixed end being fixedly connected to the mounting bracket, and the end of the central shaft away from the rotating shaft being fixedly connected to the center of the end face of the fixed end; the rotating turntable... The rotating end is sleeved on the outer circumference of the central shaft and is concentrically arranged with the central shaft. The rotating end can rotate relative to the central shaft. A third support plate is fixed to the end face of the rotating end away from the fixed end. A fourth support plate is fixed to the third support plate by a support rod. Multiple drive motors are installed on the third support plate. Multiple wrenches are rotatably connected to the fourth support plate. The tail end of each wrench extends from the fourth support plate toward the third support plate and is fixedly connected to the output end of each drive motor. Each drive motor can rotate forward or reverse simultaneously, thereby driving each wrench to rotate forward or reverse. Each wrench is used to tighten or loosen multiple bolts simultaneously.

[0022] In practical implementation, multiple bolts are often used to fix the rotating target piece, and all bolts pass through the rotating target piece to make the rotating target piece more secure when it rotates. For the rotating target piece fixed with multiple bolts, the pressure cover is provided with multiple bolt holes, and the rotating target piece is provided with through holes at positions corresponding to each bolt hole; bolts are installed in each bolt hole and corresponding through hole to achieve a fixed connection between the rotating target piece and the pressure cover.

[0023] Each bolt corresponds to a specific wrench position, and each wrench can engage with its corresponding bolt. Each wrench can rotate clockwise or counterclockwise simultaneously, thereby tightening or loosening the corresponding bolt.

[0024] When disassembling the rotating target, first connect the central shaft to the rotating shaft, then engage each wrench with each bolt and simultaneously reverse them to loosen each bolt. Then, the transfer assembly will transfer the pressure cap and the target together from the rotating shaft to the central shaft to disassemble the rotating target.

[0025] When installing the rotating target, first, the new pressure cap and the target are placed together on the central shaft. Then, the central shaft is connected to the rotating shaft. The transfer assembly then transfers the pressure cap and the target together from the central shaft to the rotating shaft. Then, each wrench is engaged with each bolt and rotated clockwise simultaneously to tighten each bolt, thus completing the installation of the rotating target.

[0026] On the other hand, a target replacement method is provided, utilizing the disassembly and assembly mechanism for disassembling and assembling the rotating target assembly as described above, including the following steps:

[0027] S1. First, move the disassembly and assembly mechanism to a position close to the old rotating target assembly, and abut the central shaft against the rotating shaft, ensuring that the center line of the central shaft coincides with the center line of the rotating shaft;

[0028] S2. When disassembling the old rotating target assembly, start each lead screw motor to rotate forward simultaneously and separately, causing each suction cup assembly to extend and adhere to the surface of the old rotating target assembly; then start each vacuum device to create a vacuum between the suction cup assembly and the part of the old rotating target assembly that is in contact with it, thereby adsorbing the old rotating target assembly; then start each lead screw motor to rotate in reverse simultaneously and separately, causing each suction cup assembly to retract and move the old rotating target assembly onto the central shaft; then turn off each vacuum device to release the old rotating target assembly from the suction cup assembly, remove the disassembly mechanism to separate the central shaft from the rotating shaft, and remove the old rotating target assembly to complete the disassembly process;

[0029] S3. When installing a new rotating target assembly, place the new rotating target assembly on the central shaft, and move the disassembly and assembly mechanism back to a position close to the installation target. Then, align the central shaft with the rotating shaft, ensuring that the center line of the central shaft coincides with the center line of the rotating shaft. Next, start each lead screw motor to rotate simultaneously and separately in the forward direction, causing each suction cup assembly to extend and push the new rotating target assembly to the target position, thus completing the installation of the new rotating target assembly.

[0030] In this solution, efficient assembly and disassembly can be achieved by utilizing the cooperation between various components. In addition, when assembling or disassembling the target piece, the end of the central shaft abuts against the opposite end of the rotating shaft, and the center line of the central shaft coincides with the center line of the rotating shaft. By assembling or disassembling the rotating target piece assembly in a "shaft-to-shaft" manner, the accuracy of the target piece installation position can be improved, solving the technical problem that the rotating target piece assembly is prone to positional deviation during installation. It also solves the technical problem that the rotating target piece assembly is prone to falling off during assembly and disassembly.

[0031] Preferably, in step S1, the disassembly and assembly mechanism is controlled and moved using a mobile device and a background processing terminal. The mobile device includes a horizontal lateral movement mechanism, a horizontal longitudinal movement mechanism, and a vertical movement mechanism. The horizontal longitudinal movement mechanism is installed on the horizontal lateral movement mechanism and can drive the horizontal longitudinal movement mechanism to move horizontally. The vertical movement mechanism is installed on the horizontal longitudinal movement mechanism and can drive the vertical movement mechanism to move horizontally. The disassembly and assembly mechanism is installed on the vertical movement mechanism and can drive the disassembly and assembly mechanism to move vertically. The vertical movement mechanism serves as the support structure for the disassembly and assembly mechanism.

[0032] The mobile device is also equipped with a first motor, a second motor and a third motor. The first motor is used to drive the horizontal longitudinal moving mechanism to move horizontally, the second motor is used to drive the vertical moving mechanism to move vertically, and the third motor is used to drive the disassembly and assembly mechanism to move vertically.

[0033] The first motor, the second motor, and the third motor are respectively equipped with a first control module, a second control module, and a third control module; the first control module, the second control module, and the third control module are used to receive instructions sent by the background processing terminal, and respectively control the first motor, the second motor, and the third motor to rotate forward or in reverse.

[0034] The disassembly and assembly mechanism is also equipped with a third control module and a fourth control module;

[0035] The third control module is used to receive instructions sent by the background processing terminal and control each lead screw motor to rotate forward or reverse simultaneously.

[0036] The fourth control module is used to receive instructions sent by the background processing terminal and control the start and stop of each of the vacuum pumping devices.

[0037] Preferably, in step S1, the method for bringing the central axis into contact with the rotation axis and ensuring that the centerline of the central axis coincides with the centerline of the rotation axis is as follows:

[0038] S1.1 Establish the XYZ coordinate system, and set the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point on the horizontal lateral movement mechanism, the horizontal longitudinal movement mechanism, and the vertical movement mechanism, respectively;

[0039] S1.2 Connect the central shaft to the rotating shaft, and ensure that the center line of the central shaft coincides with the center line of the rotating shaft. At this time, measure the coordinate values ​​of the installation endpoint positions of the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point respectively.

[0040] S1.3 Separate the central axis from the rotation axis to the disassembly endpoint position where the rotating target assembly can be removed. At this time, measure the coordinate values ​​of the disassembly endpoint position of the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point respectively, and use the disassembly endpoint position coordinate value as the initial position coordinate value of the moving device.

[0041] S1.4 On the background processing terminal, the coordinates of the installation endpoint and the disassembly endpoint are converted into the running time of the first motor, the second motor, and the third motor.

[0042] This solution employs a coordinate positioning method to improve the alignment accuracy of the "axis-to-axis" process and solves the technical problem that visual errors can lead to difficulty in alignment or large alignment errors during the "axis-to-axis" process when using manual operation.

[0043] Preferably, in step S2, when disassembling the old rotating target assembly, the mobile device is in the initial position, the background processing terminal sends a disassembly command to the mobile device, the mobile device transports the disassembly mechanism to the installation endpoint position, and then the background processing terminal sends an execution disassembly command to the disassembly mechanism, the disassembly mechanism begins to disassemble the old rotating target assembly, and after the disassembly is completed, the background processing terminal sends a reset command to the mobile device to reset the mobile device to the initial position.

[0044] In step S3, when installing the new rotating target assembly, the background processing terminal sends an installation command to the mobile device. The mobile device transports the disassembly and assembly mechanism to the installation endpoint. Then, the background processing terminal sends an execution installation command to the disassembly and assembly mechanism. The disassembly and assembly mechanism begins to install the old rotating target assembly. After the installation is completed, the background processing terminal sends a reset command to the mobile device, causing the mobile device to reset to its initial position.

[0045] The present invention has the following beneficial effects: In the disassembly and assembly mechanism disclosed in this invention, when disassembling and assembling the target piece, the end of the central shaft abuts against the opposite end of the rotating shaft, and the center line of the central shaft coincides with the center line of the rotating shaft. Therefore, by utilizing the concentric shaft principle, the rotating target piece assembly is disassembled and assembled in a "shaft-to-shaft" manner, and is moved accordingly to the central shaft or the rotating shaft. At the structural level, this can improve the accuracy of the target piece installation position, improve the disassembly and assembly efficiency, solve the technical problem that the rotating target piece assembly is prone to positional deviation during installation, and also solve the technical problem that the rotating target piece assembly is prone to falling off during disassembly and assembly.

Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0052] It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. In addition, the terms "horizontal," "vertical," etc., do not indicate that the component is required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted. In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] This invention can be applied to the field of neutron target technology, solving the technical problem that the rotating target assembly is prone to positional deviation during installation, and also solving the technical problem that the rotating target assembly is prone to falling off during disassembly and assembly.

[0054] Please see Figure 1 Based on the above-mentioned technical problems, the present invention discloses a disassembly and assembly mechanism for disassembling and assembling a rotating target assembly, wherein the rotating target assembly is used to be mounted on a rotating shaft;

[0055] The disassembly and assembly mechanism 200 is provided with a central shaft 201 corresponding to the rotating shaft 103. The central shaft 201 has the same cross-sectional diameter as the rotating shaft 103. When disassembling and assembling the rotating target assembly, the end of the central shaft 201 can abut against the opposite end of the rotating shaft 103, and the center line of the central shaft 201 coincides with the center line of the rotating shaft 103.

[0056] The disassembly and assembly mechanism 200 is provided with a transfer component, which can be adsorbed and connected to the rotating target assembly. When the end of the central shaft 201 abuts against the opposite end of the rotating shaft 103, the transfer component can drive the rotating target assembly to move on the central shaft 201 and the rotating shaft 103.

[0057] In this embodiment, when assembling or disassembling the target assembly, the end of the central shaft 201 abuts against the opposite end of the rotating shaft 103, and the centerline of the central shaft 201 coincides with the centerline of the rotating shaft 103. Therefore, by utilizing the principle of concentric shafts, the rotating target assembly is assembled or disassembled in a "shaft-to-shaft" manner, and is moved accordingly to the central shaft 201 or the rotating shaft 103. Structurally, this improves the accuracy of the target installation position, increases the assembly and disassembly efficiency, solves the technical problem of positional deviation during the installation of the rotating target assembly, and also solves the technical problem of the rotating target assembly falling off during assembly and disassembly.

[0058] As one implementation of the transfer component being able to adsorb and connect with the rotating target assembly, please refer to Figure 1 and Figure 2 The transfer assembly includes a plurality of uniformly distributed suction cup assemblies, each of which can extend and retract in a direction parallel to the extension direction of the central axis 201; the suction cup assembly includes a flexible suction cup 202, which is used to adhere to the surface of the rotating target assembly.

[0059] During the target replacement process, multiple suction cups are used to pick up or move the target piece, which solves the technical problem that the thin and fragile annular target piece may be damaged if the clamping method used in the existing technology is adopted.

[0060] When it is necessary to move the rotating target assembly, each suction cup assembly is first extended so that each flexible suction cup 202 is adsorbed onto the surface of the rotating target assembly. Then, when the transfer assembly moves, it can drive the rotating target assembly to move.

[0061] For a preferred solution of the suction cup assembly, please refer to [link / reference]. Figure 1 and Figure 2 Each of the suction cup components is a vacuum suction cup device, and each of the flexible suction cups 202 is connected to one end of a vacuum tube, and the other end of each of the vacuum tubes is connected to a vacuum pumping device (not shown in the figure).

[0062] When it is necessary to move the rotating target assembly, first extend each suction cup assembly and ensure that each suction cup is in contact with the rotating target assembly. Then turn on the vacuum device to create a vacuum between the part of the flexible suction cup 202 that is in contact with the rotating target assembly, thereby achieving adsorption of the rotating target assembly.

[0063] As one way to achieve the extension and retraction of various suction cup components, please refer to [link / reference]. Figure 1 and Figure 2 The flexible suction cup 202 is provided with a telescopic rod at the end away from the rotating target assembly. The telescopic rod can drive the flexible suction cup 202 to extend and retract in a direction parallel to the extension direction of the central axis 201.

[0064] As another way to achieve the extension and retraction of each suction cup component, please refer to [link / reference]. Figure 1 and Figure 2 The disassembly and assembly mechanism 200 is mounted on the support structure via a mounting bracket 211. A first bracket plate 203 and a second bracket plate 204 are fixed on the mounting bracket 211. Each suction cup assembly is mounted on the first bracket plate 203. A plurality of lead screws 205 are fixed between the first bracket plate 203 and the second bracket plate 204 corresponding to each suction cup assembly. Each suction cup assembly has a lead screw slider 206 at one end extending out of the first bracket plate 203. Each lead screw slider 206 is threadedly connected to the corresponding lead screw 205. A lead screw motor (not shown in the figure) is fixed at one end extending out of the second bracket plate 204 of each lead screw 205. Each lead screw motor can rotate forward or reverse simultaneously and can drive each lead screw slider 206 to move on the corresponding lead screw 205.

[0065] When rotating forward, the lead screw slider 206 can move along the corresponding lead screw 205 in a direction away from the lead screw motor, causing the suction cup assembly to extend. When rotating in reverse, the lead screw slider 206 can move along the corresponding lead screw 205 in a direction closer to the lead screw motor, causing the suction cup assembly to retract.

[0066] In conjunction with the above embodiments, a target replacement method is also provided, utilizing the disassembly and assembly mechanism 200 for disassembling and assembling the rotating target assembly as described above, including the following steps:

[0067] S1. First, move the disassembly and assembly mechanism 200 to a position close to the old rotating target assembly, and abut the central shaft 201 against the rotating shaft 103, ensuring that the center line of the central shaft 201 coincides with the center line of the rotating shaft 103;

[0068] S2. When disassembling the old rotating target assembly, start each lead screw motor to rotate forward simultaneously and separately, causing each suction cup assembly to extend and adhere to the surface of the old rotating target assembly; then start each vacuum device to create a vacuum between the suction cup assembly and the part of the old rotating target assembly that is in contact with it, thereby adsorbing the old rotating target assembly; then start each lead screw motor to rotate in reverse simultaneously and separately, causing each suction cup assembly to retract and move the old rotating target assembly onto the central shaft 201; then turn off each vacuum device to release the old rotating target assembly from the suction cup assembly, remove the disassembly mechanism 200, separate the central shaft 201 from the rotating shaft 103, remove the old rotating target assembly, and complete the disassembly process;

[0069] S3. When installing a new rotating target assembly, place the new rotating target assembly on the central shaft 201, and move the disassembly and assembly mechanism 200 back to a position close to the installation target. Then, align the central shaft 201 with the rotating shaft 103, ensuring that the center line of the central shaft 201 coincides with the center line of the rotating shaft 103. Next, start each lead screw motor to rotate simultaneously and separately, causing each suction cup assembly to extend and push the new rotating target assembly to the target position, thus completing the installation of the new rotating target assembly.

[0070] In this solution, efficient assembly and disassembly can be achieved by utilizing the cooperation between various components. In addition, when assembling and disassembling the target piece, the end of the central shaft 201 abuts against the opposite end of the rotating shaft 103, and the center line of the central shaft 201 coincides with the center line of the rotating shaft 103. By assembling and disassembling the rotating target piece assembly in a "shaft-to-shaft" manner, the accuracy of the target piece installation position can be improved, solving the technical problem that the rotating target piece assembly is prone to positional deviation during installation. It also solves the technical problem that the rotating target piece assembly is prone to falling off during assembly and disassembly.

[0071] Specifically, in step S1, please refer to... Figure 1 and Figure 3The disassembly / assembly mechanism 200 is controlled and moved using a mobile device 300 and a back-end processing terminal. The mobile device 300 includes a horizontal moving mechanism 302, a horizontal moving mechanism 303, and a vertical moving mechanism 301. The horizontal moving mechanism 303 is mounted on the horizontal moving mechanism 302, and the horizontal moving mechanism 302 can drive the horizontal moving mechanism 303 to move horizontally. The vertical moving mechanism 301 is mounted on the horizontal moving mechanism 303, and the horizontal moving mechanism 303 can drive the vertical moving mechanism 301 to move vertically. The disassembly / assembly mechanism 200 is mounted on the vertical moving mechanism 301, and the vertical moving mechanism 301 can drive the disassembly / assembly mechanism 200 to move vertically. The vertical moving mechanism serves as the support structure for the disassembly / assembly mechanism 200.

[0072] The moving device 300 is also provided with a first motor 304, a second motor 305 and a third motor 306. The first motor 304 is used to drive the horizontal longitudinal moving mechanism 303 to move horizontally, the second motor 305 is used to drive the vertical moving mechanism 301 to move horizontally, and the third motor 306 is used to drive the disassembly and assembly mechanism 200 to move vertically.

[0073] The first motor 304, the second motor 305, and the third motor 306 are respectively equipped with a first control module, a second control module, and a third control module; the first control module, the second control module, and the third control module are used to receive instructions sent by the background processing terminal, and respectively control the first motor 304, the second motor 305, and the third motor 306 to rotate forward or in reverse.

[0074] The disassembly and assembly mechanism 200 is also equipped with a third control module and a fourth control module;

[0075] The third control module is used to receive instructions sent by the background processing terminal and control each lead screw motor to rotate forward or reverse simultaneously.

[0076] The fourth control module is used to receive instructions sent by the background processing terminal and control the start and stop of each of the vacuum pumping devices.

[0077] Specifically, in step S1, the following method is used to achieve the abutment of the central shaft 201 with the rotation shaft 103 and to ensure that the center line of the central shaft 201 coincides with the center line of the rotation shaft 103:

[0078] S1.1 Establish the XYZ coordinate system, and set the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point on the horizontal lateral moving mechanism 302, the horizontal longitudinal moving mechanism 303, and the vertical moving mechanism 301, respectively;

[0079] S1.2 Connect the central shaft 201 to the rotating shaft 103, and ensure that the center line of the central shaft 201 coincides with the center line of the rotating shaft 103. At this time, measure the coordinate values ​​of the installation endpoint positions of the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point respectively.

[0080] S1.3 Separate the central shaft 201 from the rotating shaft 103 to the disassembly endpoint position where the rotating target assembly can be removed. At this time, measure the coordinate values ​​of the disassembly endpoint position of the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point respectively, and use the disassembly endpoint position coordinate value as the initial position coordinate value of the moving device 300.

[0081] S1.4 On the background processing terminal, the coordinate values ​​of the installation endpoint and the coordinate values ​​of the disassembly endpoint are converted into the running time of the first motor 304, the second motor 305, and the third motor 306.

[0082] This solution employs a coordinate positioning method to improve the alignment accuracy of the "axis-to-axis" process and solves the technical problem that visual errors can lead to difficulty in alignment or large alignment errors during the "axis-to-axis" process when using manual operation.

[0083] Specifically, as one embodiment of establishing the XYZ coordinate system, the center point of the end face where the rotation axis 103 and the central axis 201 are connected is taken as the origin of the coordinate system, the horizontal direction away from the rotation axis 103 and towards the central axis 201 is taken as the positive X-axis, the right direction towards the rotation axis 103 and along the horizontal longitudinal direction is taken as the positive Y-axis, and the vertical upward direction is taken as the positive Z-axis.

[0084] Specifically, in step S1.4, the coordinate values ​​of the installation endpoint and the disassembly endpoint are converted into the running time of the first motor 304, the second motor 305, and the third motor 306 on the background processing terminal. By constructing the functional relationship between the running time of the first motor 304, the second motor 305, and the third motor 306 and the moving distance of the horizontal moving mechanism 302, the horizontal moving mechanism 303, and the vertical moving mechanism 301, respectively, the moving distance value is obtained based on the difference between the coordinate values ​​of the installation endpoint and the disassembly endpoint, and thus the running time of the motor is obtained.

[0085] Specifically, in step S2, when disassembling the old rotating target assembly, the mobile device 300 is in the initial position. The background processing terminal sends a disassembly command to the mobile device 300, and the mobile device 300 transports the disassembly and assembly mechanism 200 to the installation endpoint position. Then, the background processing terminal sends an execution disassembly command to the disassembly and assembly mechanism 200, and the disassembly and assembly mechanism 200 begins to disassemble the old rotating target assembly. After the disassembly is completed, the background processing terminal sends a reset command to the mobile device 300, so that the mobile device 300 is reset to the initial position.

[0086] In step S3, when installing the new rotating target assembly, the background processing terminal sends an installation command to the mobile device 300. The mobile device 300 transports the disassembly and assembly mechanism 200 to the installation endpoint position. Then, the background processing terminal sends an execution installation command to the disassembly and assembly mechanism 200. The disassembly and assembly mechanism 200 begins to install the old rotating target assembly. After the installation is completed, the background processing terminal sends a reset command to the mobile device 300, causing the mobile device 300 to reset to its initial position.

[0087] Specifically, the disassembly command refers to the background processing terminal sending forward rotation commands and running times to the first motor 304, the second motor 305, and the third motor 306 respectively, so as to drive the mobile device 300 to transport the disassembly and assembly mechanism 200 to the installation endpoint position.

[0088] Specifically, the execution of the disassembly command means that the background processing terminal sends a forward rotation command to the third control module to control each lead screw motor to rotate forward, drive each suction cup assembly to extend and abut against the old rotating target plate assembly, then the background processing terminal sends an opening command to the fourth control module to open the vacuum device to adsorb the old rotating target plate assembly, and then the background processing terminal sends a reverse rotation command to the third control module to control each lead screw motor to rotate in reverse, drive each suction cup assembly to retract and move the old rotating target plate assembly onto the central shaft 201.

[0089] Specifically, the installation command refers to the background processing terminal sending forward rotation commands and running times to the first motor 304, the second motor 305, and the third motor 306 respectively, so as to drive the mobile device 300 to transport the disassembly and assembly mechanism 200 to the installation endpoint.

[0090] Specifically, the execution of the installation command means that the background processing terminal sends a forward rotation command to the third control module to control each lead screw motor to rotate forward, drive each suction cup assembly to extend and push the new rotating target assembly to the target position, and then the background processing terminal sends a reverse rotation command to the third control module to control each lead screw motor to rotate in reverse and drive each suction cup assembly to retract.

[0091] Specifically, sending a reset command to the mobile device 300 means that the background processing terminal sends a reverse command and a running time to the first motor 304, the second motor 305, and the third motor 306 respectively, so as to drive the mobile device 300 to reset to the initial position.

[0092] Additionally, as one embodiment of the rotating target assembly, please refer to... Figure 3 In this embodiment, the rotating target assembly includes a rotating target 101, which is mounted on a rotating shaft 103 via a pressure cap 104, which is used to loop around the rotating shaft 103.

[0093] For specific implementation details, please refer to [link / reference]. Figure 1 and Figure 2 The rotating target piece 101 is fixed with multiple bolts 105, and all bolts 105 pass through the rotating target piece 101, which makes the rotating target piece 101 more secure when rotating. For the rotating target piece 101 fixed with multiple bolts 105, the pressure cover 104 is provided with multiple bolt holes, and the rotating target piece 101 is provided with through holes at positions corresponding to each bolt hole. Bolts 105 are installed in each bolt hole and each corresponding through hole to achieve a fixed connection between the rotating target piece 101 and the pressure cover 104.

[0094] As an example of fixing a rotating target using a gland and bolts, please refer to... Figure 1 and Figure 2 A rotating turntable 212 is mounted on the mounting bracket 211. The rotating turntable 212 has a fixed end 213 and a rotating end 214. The fixed end 213 is fixedly connected to the mounting bracket 211. The end of the central shaft 201 away from the rotating shaft 103 is fixedly connected to the center of the end face of the fixed end 213. The rotating end 214 is sleeved on the outer periphery of the central shaft 201 and is concentrically arranged with the central shaft 201. The rotating end 214 can rotate relative to the central shaft 201. A third support plate 208 is fixed to the end face of the rotating end 214 away from the fixed end 213. The third support plate 208 is fixed to the fourth support plate 209 by a support rod. Multiple drive motors 210 are mounted on the third support plate 208, and multiple wrenches 207 are rotatably connected to the fourth support plate 209. The tail end of each wrench 207 extends from the fourth support plate 209 toward the third support plate 208 and is fixedly connected to the output end of each drive motor 210. Each drive motor 210 can rotate forward or reverse simultaneously, thereby driving each wrench 207 to rotate forward or reverse. Each wrench 207 is used to tighten or loosen multiple bolts 105 simultaneously.

[0095] Each bolt 105 corresponds to a position of a wrench 207, and each wrench 207 can engage with the corresponding bolt 105. Each wrench 207 can rotate clockwise or counterclockwise simultaneously, thereby tightening or loosening the corresponding bolt 105.

[0096] When disassembling the rotating target 101, first connect the central shaft 201 with the rotating shaft 103, then engage each wrench 207 with each bolt 105 and simultaneously reverse them to loosen each bolt 105. Then, the transfer assembly transfers the pressure cap 104 and the target together from the rotating shaft 103 to the central shaft 201 to achieve the disassembly of the rotating target 101.

[0097] When installing the rotating target 101, first, the new pressure cap 104 and the target are fitted together onto the central shaft 201. Then, the central shaft 201 is connected to the rotating shaft 103. Then, the pressure cap 104 and the target are transferred from the central shaft 201 to the rotating shaft 103 by the transfer assembly. Then, each wrench 207 is engaged with each bolt 105 and rotated clockwise at the same time to tighten each bolt 105, thus realizing the installation of the rotating target 101.

[0098] Specifically, each of the bolts 105 has a locking groove at one end facing each of the wrenches 207, and the locking end of each wrench 207 can engage with the locking groove of the corresponding bolt 105.

[0099] Specifically, the bolt 105 is an internal hex bolt 105, and the wrench 207 is an internal hex wrench 207.

[0100] In another embodiment of the rotating target assembly, the rotating target assembly includes a rotating target 101. The rotating target 101 is mounted on a rotating shaft 103 via a quick-release device. The quick-release device is fitted around the outer periphery of the end of the rotating shaft 103 facing the central axis. The rotating shaft has a insertion channel, and a spring piece extends radially from the inner wall of the insertion channel. A connector is provided at one end of the quick-release device facing the rotating target, corresponding to the insertion channel. A spring is fitted onto the connector, and the end of the connector is provided with a radially contracting snap-fit ​​groove. When disassembling the rotating target assembly, the central shaft abuts against the quick-release device. When the suction cup assembly attracts the rotating target and pulls it off the rotating shaft, the spring deforms and disengages from the snap-fit ​​groove, and the connector separates from the insertion channel, thus achieving quick release of the target. When installing the rotating target assembly, the central shaft abuts against the quick-release device, the connector is inserted into the insertion channel, the spring deforms in the opposite direction, and snaps into the snap-fit ​​groove, thus achieving installation of the target assembly.
