Description

Technical Field

[0001] This application relates to the field of magnetic shielding cabin technology, and more particularly to an assembly tooling and method for a modular magnetic shielding cabin. Background Technology

[0002] Current geomagnetic shielding rooms, as devices that shield the Earth's magnetic field and fluctuations in the external magnetic field, are mainly used in cutting-edge quantum science, magnetic medicine for the heart and brain, and aerospace and defense, to provide a clean magnetic measurement environment. The function of a magnetic shielding room is to shield the Earth's magnetic field and other interfering magnetic fields, creating a uniform, near-zero magnetic environment inside, thus minimizing magnetic interference when experimental instruments are placed within.

[0003] For static magnetic fields and low-frequency alternating magnetic fields, current methods primarily utilize the flux shunting effect of high-permeability materials for static magnetic field shielding, while for low-frequency alternating magnetic fields, shielding is achieved through the eddy current elimination effect of high-conductivity materials. Generally, a multi-panel splicing method is employed. Since the size of the splicing gaps in the soft magnetic materials directly affects the performance of the magnetic shielding room, traditional installation and assembly methods are not only complex but also cannot guarantee the dimensions of the splicing gaps.

[0086] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0087] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0088] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0089] like Figures 1 to 13As shown, according to a first aspect of the embodiments of this application, an assembly fixture for a modular magnetic shielding cabin is provided, comprising: a bracket 110; a workbench 120, the workbench 120 being disposed on the bracket 110, the workbench 120 having multiple sets of positioning pin holes 130 formed thereon; a top and bottom plate positioning assembly 140, the top and bottom plate positioning assembly 140 being detachably connected to the workbench 120 through a first set of positioning pin holes 130; a side panel positioning assembly 150, the side panel positioning assembly 150 being detachably connected to the workbench 120 through a second set of positioning pin holes 130; a door panel positioning assembly 160, the door panel positioning assembly 160 being detachably connected to the workbench 120 through a third set of positioning pin holes 130; and a rear plate positioning assembly 170, the rear plate positioning assembly 170 being detachably connected to the workbench 120 through a fourth set of positioning pin holes 130.

[0090] The modular magnetic shielding cabin assembly fixture provided in this application embodiment includes a bracket 110, a workbench 120, a top and bottom plate positioning assembly 140, a side panel positioning assembly 150, a door panel positioning assembly 160, and a rear plate positioning assembly 170. The workbench 120 has multiple sets of positioning pin holes 130. During the assembly of the magnetic shielding cabin, one of the top and bottom plate positioning assemblies 140, 150, 160, and 170 can be fixed using the workbench 120. For example, in one assembly sequence, only the top and bottom plate positioning assembly 140 can be initially installed on the workbench 120. This positioning assembly 140 positions the top and bottom plates of the magnetic shielding cabin, making the assembly of the top and bottom plates more precise. Then, only the top and bottom plate positioning assembly 170 can be installed on the workbench 120. A side panel positioning component 150 is installed on the workbench 120 to position the side panels of the magnetic shielding cabin for more precise assembly. Similarly, a door panel positioning component 160 is installed on the workbench 120 to position the door panels for more precise assembly. Likewise, a rear panel positioning component 170 is installed on the workbench 120 to position the rear panel for more precise assembly. Finally, the precisely assembled top, bottom, side, door, and rear panels are assembled, resulting in more precise modular magnetic shielding cabin assembly, ensuring consistency in the size of the seams between different modules, simplifying the assembly process, and improving the performance of the magnetic shielding room.

[0091] like Figures 1 to 2As shown, in one feasible embodiment, the top and bottom plate positioning assembly 140 includes: a top and bottom plate frame positioning member 141, the bottom of which is provided with a pivot pin 200, and the top and bottom plate frame positioning member 141 is connected to a portion of the positioning pin holes 130 in the first set of positioning pin holes 130 via the pivot pin 200; and a top and bottom plate frame limiting block 142, on which a pivot pin 200 is provided, and the top and bottom plate frame limiting block 142 is connected to a portion of the positioning pin holes 130 in the first set of positioning pin holes 130 via the pivot pin 200. There are at least two top and bottom plate frame limiting blocks 142, arranged in the middle of the worktable 120, with the two top and bottom plate frames limiting... A gap is formed between blocks 142 to accommodate the top and bottom plate frame; a top and bottom plate conductive layer limiting block 143 is disposed on the top and bottom plate frame positioning member 141 and is used to limit the conductive layer of the top and bottom plates of the modular magnetic shielding cabin; a top and bottom plate magnetic conductive layer limiting block 144 is disposed on the top and bottom plate conductive layer limiting block 143 and is used to limit the magnetic conductive layer of the top and bottom plates of the modular magnetic shielding cabin; wherein, the top and bottom plate conductive layer limiting block 143 is connected to the top and bottom plate frame positioning member 141 by a shaft pin 200, and the top and bottom plate magnetic conductive layer limiting block 144 is connected to the top and bottom plate conductive layer limiting block 143 by a shaft pin 200.

[0092] In this technical solution, the structural composition of the top and bottom plate positioning assembly 140 is further provided. The top and bottom plate positioning assembly 140 includes a top and bottom plate frame positioning component 141, a top and bottom plate frame limiting block 142, a top and bottom plate conductive layer limiting block 143, and a top and bottom plate magnetic conductive layer limiting block 144. Based on this, during the assembly of the top and bottom plates of the modular magnetic shielding cabin, the top and bottom plate frame positioning component 141 can be set on both sides of the workbench 120 through the first set of positioning pin holes 130, and at least two top and bottom plate frame limiting blocks 142 can be arranged in the middle of the workbench 120. In this case, a positioning gap can be formed between the two top and bottom plate frame positioning components 141, and the two ends of the frame of the top or bottom plate can abut against the two top and bottom plate frame positioning components 141 respectively. The top and bottom plate frame limiting block 142 located in the middle of the workbench 120 can clamp the frame of the top or bottom plate, thereby completing the fixing of the frame of the top or bottom plate.

[0093] After the frame of the top or bottom plate is fixed, the top and bottom plate conductive layer limiting block 143 can be set on the top and bottom plate frame positioning piece 141 by means of the shaft pin 200 and the pin hole 130. The conductive layer limiting block 143 can limit the conductive layer of the top or bottom plate, so that the conductive layer of the top or bottom plate can be accurately assembled onto the frame of the top or bottom plate.

[0094] After the conductive layer of the top or bottom plate is assembled, the magnetic layer limiting block 144 of the top and bottom plates can be inserted into the conductive layer limiting block 143 of the top and bottom plates by means of the shaft pin 200 and the pin hole 130. Then the electromagnetic layer of the top or bottom plate can be limited by the magnetic layer limiting block 144 of the top and bottom plates to complete the assembly of the electromagnetic layer.

[0095] This enables high-precision assembly of the top and bottom plates, improving their assembly accuracy.

[0096] It is understandable that the top and bottom plates have the same structure, so they can be assembled using the same top and bottom plate positioning assembly 140.

[0097] It is understandable that all the axle pins 200 can have the same structure, with the shaft hole being a diamond-shaped hole. The shape of the axle pin 200 is adapted to the shape of the diamond-shaped hole. This setting can play a foolproof role and facilitate the quick assembly and disassembly of the top and bottom plate frame positioning parts 141, top and bottom plate frame limiting blocks 142, top and bottom plate conductive layer limiting blocks 143, and top and bottom plate magnetic layer limiting blocks 144 onto the worktable 120.

[0098] It is understood that there can be multiple sets of top and bottom plate conductive layer limiting blocks 143. For example, each top and bottom plate frame positioning member 141 has a top and bottom plate conductive layer limiting block 143 arranged at both ends. The top and bottom plate conductive layer limiting block 143 has a limiting part that conforms to the conductive layer of the top or bottom plate. The limiting part can be corner-shaped, which can limit the conductive layer.

[0099] It is understood that there can be multiple sets of top and bottom plate magnetic layer limiting blocks 144. For example, each top and bottom plate frame positioning member 141 has a top and bottom plate magnetic layer limiting block 144 at both ends. The top and bottom plate magnetic layer limiting block 144 has a limiting part that conforms to the magnetic layer of the top or bottom plate. The limiting part can be corner-shaped, which can limit the magnetic layer.

[0100] like Figures 3 to 4As shown, in one feasible embodiment, the side panel positioning assembly 150 includes: a side panel frame positioning member 151, with a pivot pin 200 at its bottom, the side panel frame positioning member 151 being connected to a portion of the positioning pin holes 130 in the second set of positioning pin holes 130 via the pivot pin 200; and a side panel frame limiting block 152, with a pivot pin 200 on the side panel frame limiting block 152, the side panel frame limiting block 152 being connected to a portion of the positioning pin holes 130 in the second set of positioning pin holes 130 via the pivot pin 200. There are at least two side panel frame limiting blocks 152, arranged in the middle of the worktable 120, with the two side panel frames limiting... A gap is formed between blocks 152 to accommodate the side panel frame; a side panel conductive layer limiting block 153 is disposed on the side panel frame positioning member 151 to limit the conductive layer of the side panel of the modular magnetic shielding cabin; a side panel magnetic layer limiting block 154 is disposed on the side panel conductive layer limiting block 153 to limit the magnetic layer of the side panel of the modular magnetic shielding cabin; wherein, the side panel conductive layer limiting block 153 is connected to the side panel frame positioning member 151 by a shaft pin 200, and the side panel magnetic layer limiting block 154 is connected to the side panel conductive layer limiting block 153 by a shaft pin 200.

[0101] This technical solution further provides the structural composition of the side panel positioning assembly 150. The side panel positioning assembly 150 is basically the same in style as the top and bottom panel positioning assembly 140. The main differences between the two are in the assembly position and the dimensions of the specific components. The assembly position and dimensions of these components are adapted to the dimensions of the side panel frame.

[0102] In this technical solution, the structural composition of the side panel positioning assembly 150 is further provided. The side panel positioning assembly 150 includes a side panel frame positioning component 151, a side panel frame limiting block 152, a side panel conductive layer limiting block 153, and a side panel magnetic conductive layer limiting block 154. Based on this, in the side panel assembly process of the modular magnetic shielding cabin, the side panel frame positioning component 151 can be set on both sides of the workbench 120 through the second set of positioning pin holes 130, and at least two side panel frame limiting blocks 152 can be arranged in the middle of the workbench 120. In this case, a positioning gap can be formed between the two side panel frame positioning components 151, and the two ends of the side panel frame can abut against the two side panel frame positioning components 151 respectively. The side panel frame limiting block 152 located in the middle of the workbench 120 can clamp the side panel frame, thereby completing the fixing of the side panel frame.

[0103] After the side panel frame is fixed, the side panel conductive layer limiting block 153 can be set on the side panel frame positioning member 151 by inserting the shaft pin 200 into the pin hole 130. The conductive layer limiting block 153 can limit the conductive layer of the side panel, so that the conductive layer of the side panel can be accurately assembled onto the side panel frame.

[0104] After the conductive layer of the side panel is assembled, the magnetic layer limiting block 154 of the side panel can be inserted into the conductive layer limiting block 153 of the side panel by means of the shaft pin 200 and the pin hole 130. Then the electromagnetic layer of the side panel can be limited by the magnetic layer limiting block 154 of the side panel to complete the assembly of the electromagnetic layer.

[0105] This enables high-precision assembly of the side panels, improving their assembly accuracy.

[0106] It is understandable that all the pins 200 can have the same structure, with the shaft hole being a diamond-shaped hole. The shape of the pin 200 is adapted to the shape of the diamond-shaped hole. This setting can play a foolproof role and facilitate the quick assembly and disassembly of the side panel frame positioning block 151, the side panel frame limiting block 152, the side panel conductive layer limiting block 153, and the side panel magnetic layer limiting block 154 onto the worktable 120.

[0107] It is understood that there can be multiple sets of side panel conductive layer limiting blocks 153. For example, each side panel frame positioning member 151 has a side panel conductive layer limiting block 153 arranged at both ends. The side panel conductive layer limiting block 153 has a limiting part that conforms to the conductive layer of the side panel. The limiting part can be corner-shaped, which can limit the conductive layer.

[0108] It is understood that there can be multiple sets of side panel magnetic layer limiting blocks 154. For example, each side panel frame positioning member 151 has a side panel magnetic layer limiting block 154 arranged at both ends. The side panel magnetic layer limiting block 154 has a limiting part that conforms to the magnetic layer of the side panel. The limiting part can be corner-shaped, which can limit the magnetic layer.

[0109] like Figure 5As shown, in one feasible embodiment, the door panel positioning assembly 160 includes: a door panel frame positioning member 161, with a pivot pin 200 at its bottom, the door panel frame positioning member 161 being connected to a portion of the positioning pin holes 130 in the third set of positioning pin holes 130 via the pivot pin 200; and a door panel frame limiting block 162, with a pivot pin 200 on the door panel frame limiting block 162, the door panel frame limiting block 162 being connected to a portion of the positioning pin holes 130 in the third set of positioning pin holes 130 via the pivot pin 200. There are at least two door panel frame limiting blocks 162, arranged in the middle of the workbench 120, with the two door panel frames... A gap is formed between the limiting blocks 162 to accommodate the door panel frame; a door panel conductive layer limiting block 163 is disposed on the door panel frame positioning member 161 and is used to limit the conductive layer of the door panel of the modular magnetic shielding cabin; a door panel magnetic layer limiting block 164 is disposed on the door panel conductive layer limiting block 163 and is used to limit the magnetic layer of the door panel of the modular magnetic shielding cabin; wherein, the door panel conductive layer limiting block 163 is connected to the door panel frame positioning member 161 by a shaft pin 200, and the door panel magnetic layer limiting block 164 is connected to the door panel conductive layer limiting block 163 by a shaft pin 200.

[0110] This technical solution further provides the structural composition of the door panel positioning assembly 160. The door panel positioning assembly 160 is basically the same in style as the side panel positioning assembly 150, with the main differences being in the assembly position and the dimensions of specific components. The assembly position and dimensions of these components are adapted to the dimensions of the door panel frame.

[0111] In this technical solution, the structural composition of the door panel positioning assembly 160 is further provided. The door panel positioning assembly 160 includes a door panel frame positioning component 161, a door panel frame limiting block 162, a door panel conductive layer limiting block 163, and a door panel magnetic conductive layer limiting block 164. Based on this, in the door panel assembly process of the modular magnetic shielding cabin, the door panel frame positioning component 161 can be set on both sides of the workbench 120 through the second set of positioning pin holes 130, and at least two door panel frame limiting blocks 162 can be arranged in the middle of the workbench 120. In this case, a positioning gap can be formed between the two door panel frame positioning components 161, and the two ends of the door panel frame can abut against the two door panel frame positioning components 161 respectively. The door panel frame limiting block 162 located in the middle of the workbench 120 can clamp the door panel frame, thereby completing the fixing of the door panel frame.

[0112] After the frame of the door panel is fixed, the door panel conductive layer limiting block 163 can be set on the door panel frame positioning part 161 by inserting the shaft pin 200 into the pin hole 130. The conductive layer limiting block 163 can limit the conductive layer of the door panel, so that the conductive layer of the door panel can be accurately assembled onto the frame of the door panel.

[0113] After the conductive layer of the door panel is assembled, the magnetic layer limiting block 164 of the door panel can be inserted into the conductive layer limiting block 163 of the door panel by means of the shaft pin 200 and the pin hole 130. Then the electromagnetic layer of the door panel can be limited by the magnetic layer limiting block 164 of the door panel to complete the assembly of the electromagnetic layer.

[0114] This enables high-precision assembly of the door panel, improving the assembly accuracy of the door panel.

[0115] It is understandable that all the axle pins 200 can have the same structure, with the shaft hole being a diamond-shaped hole. The shape of the axle pin 200 is adapted to the shape of the diamond-shaped hole. This setting can play a foolproof role and facilitate the quick assembly and disassembly of the door panel frame positioning component 161, door panel frame limiting block 162, door panel conductive layer limiting block 163, and door panel magnetic layer limiting block 164 onto the worktable 120.

[0116] It is understandable that there can be multiple sets of door panel conductive layer limiting blocks 163. For example, each door panel frame positioning component 161 has a door panel conductive layer limiting block 163 arranged at both ends. The door panel conductive layer limiting block 163 has a limiting part that conforms to the conductive layer of the door panel. Specifically, the limiting part can be corner-shaped, which enables the conductive layer to be limited.

[0117] It is understandable that there can be multiple sets of door panel magnetic layer limiting blocks 164. For example, each door panel frame positioning component 161 has a door panel magnetic layer limiting block 164 arranged at both ends. The door panel magnetic layer limiting block 164 has a limiting part that conforms to the magnetic layer of the door panel. The limiting part can be corner-shaped, which enables the magnetic layer to be limited.

[0118] like Figures 6 to 7As shown, in one feasible embodiment, the rear plate positioning assembly 170 includes: a rear plate frame positioning member 171, with a pivot pin 200 at its bottom, the rear plate frame positioning member 171 being connected to a portion of the positioning pin holes 130 in the fourth set of positioning pin holes 130 via the pivot pin 200; and a rear plate frame limiting block 172, with a pivot pin 200 on the rear plate frame limiting block 172, the rear plate frame limiting block 172 being connected to a portion of the positioning pin holes 130 in the fourth set of positioning pin holes 130 via the pivot pin 200. There are at least two rear plate frame limiting blocks 172, arranged in the middle of the worktable 120, with the two rear plate frames... A gap is formed between the limiting blocks 172 to accommodate the rear plate frame; a rear plate conductive layer limiting block 173 is disposed on the rear plate frame positioning member 171 to limit the conductive layer of the rear plate of the modular magnetic shielding cabin; a rear plate magnetic conductive layer limiting block 174 is disposed on the rear plate conductive layer limiting block 173 to limit the magnetic conductive layer of the rear plate of the modular magnetic shielding cabin; wherein, the rear plate conductive layer limiting block 173 is connected to the rear plate frame positioning member 171 by a shaft pin 200, and the rear plate magnetic conductive layer limiting block 174 is connected to the rear plate conductive layer limiting block 173 by a shaft pin 200.

[0119] This technical solution further provides the structural composition of the rear panel positioning assembly 170. The rear panel positioning assembly 170 is basically the same in style as the door panel positioning assembly 160, with the main differences being in the assembly position and the dimensions of specific components. The assembly position and dimensions of these components are adapted to the dimensions of the rear panel frame.

[0120] In this technical solution, the structure of the rear plate positioning assembly 170 is further provided. The rear plate positioning assembly 170 includes a rear plate frame positioning component 171, a rear plate frame limiting block 172, a rear plate conductive layer limiting block 173, and a rear plate magnetic conductive layer limiting block 174. Based on this, in the assembly process of the rear plate of the modular magnetic shielding cabin, the rear plate frame positioning component 171 can be set on both sides of the workbench 120 through the second set of positioning pin holes 130, and at least two rear plate frame limiting blocks 172 can be arranged in the middle of the workbench 120. In this case, a positioning gap can be formed between the two rear plate frame positioning components 171, and the two ends of the rear plate frame can abut against the two rear plate frame positioning components 171 respectively. The rear plate frame limiting block 172 located in the middle of the workbench 120 can clamp the frame of the rear plate, thereby fixing the frame of the rear plate.

[0121] After the frame of the rear plate is fixed, the rear plate conductive layer limiting block 173 can be set on the rear plate frame positioning piece 171 by inserting the shaft pin 200 into the pin hole 130. The conductive layer limiting block 173 can limit the conductive layer of the rear plate, so that the conductive layer of the rear plate can be accurately assembled onto the frame of the rear plate.

[0122] After the conductive layer of the rear plate is assembled, the magnetic layer limiting block 174 of the rear plate can be inserted into the conductive layer limiting block 173 of the rear plate by means of the shaft pin 200 and the pin hole 130. Then the electromagnetic layer of the rear plate can be limited by the magnetic layer limiting block 174 of the rear plate to complete the assembly of the electromagnetic layer.

[0123] This enables high-precision assembly of the rear panel and improves the assembly accuracy of the rear panel.

[0124] It is understandable that all the axle pins 200 can have the same structure, with the shaft hole being a diamond-shaped hole. The shape of the axle pin 200 is adapted to the shape of the diamond-shaped hole. This setting can play a foolproof role and facilitate the quick assembly and disassembly of the rear plate frame positioning block 171, the rear plate frame limiting block 172, the rear plate conductive layer limiting block 173, and the rear plate magnetic layer limiting block 174 onto the worktable 120.

[0125] It is understandable that there can be multiple sets of back plate conductive layer limiting blocks 173. For example, each back plate frame positioning member 171 has a back plate conductive layer limiting block 173 arranged at both ends. The back plate conductive layer limiting block 173 has a limiting part that conforms to the conductive layer of the back plate. Specifically, the limiting part can be corner-shaped, which can limit the conductive layer.

[0126] It is understandable that there can be multiple sets of back plate magnetic layer limiting blocks 174. For example, each back plate frame positioning member 171 has a back plate magnetic layer limiting block 174 arranged at both ends. The back plate magnetic layer limiting block 174 has a limiting part that conforms to the magnetic layer of the back plate. The limiting part can be corner-shaped, which can limit the magnetic layer.

[0127] In one feasible implementation, the hole diameters of the first, second, third, and fourth sets of positioning pin holes are different. This arrangement can prevent misalignment during assembly of the top and bottom plate positioning components, side panel positioning components, door panel positioning components, and rear panel positioning components, thereby improving assembly efficiency.

[0128] In one feasible implementation, the shapes of the pin holes in the first group, the second group, the third group, and the fourth group are different; this arrangement can avoid misalignment between the top and bottom plate positioning components, the side panel positioning components, the door panel positioning components, and the rear panel positioning components, thereby improving assembly efficiency.

[0129] In one feasible implementation, the second set of locating pin holes is located near the edge of the worktable, the first set of locating pin holes is located near the center of the worktable, and the third set of locating pin holes is arranged between the first and second sets of locating pin holes. This arrangement can prevent misalignment during assembly of the top and bottom plate locating components, side panel locating components, door panel locating components, and rear panel locating components, thereby improving assembly efficiency.

[0130] In one feasible implementation, a marker 180 is formed on the worktable 120. The marker 180 is used to calibrate the positioning component to which the positioning pin hole 130 belongs. The positioning pin hole 130 is a diamond-shaped pin hole 130.

[0131] In this technical solution, the structure of the workbench 120 is further provided. The workbench 120 can be formed with a marking element 180. The marking element 180 can be used to mark the pin hole 130 to prevent misalignment between the top and bottom plate positioning assembly 140, the side panel positioning assembly 150, the door panel positioning assembly 160 and the rear plate positioning assembly 170, thereby improving the efficiency of the assembly tooling of the modular magnetic shielding cabin.

[0132] In one feasible implementation, the assembly tooling for the modular magnetic shielding cabin further includes a handle 190, which is disposed on the top and bottom plate positioning assembly 140, the side panel positioning assembly 150, the door panel positioning assembly 160, and the rear panel positioning assembly 170.

[0133] In this technical solution, the assembly tooling of the modular magnetic shielding cabin is further provided. The assembly tooling of the modular magnetic shielding cabin may also include handles 190. The top and bottom plate positioning components 140, side panel positioning components 150, door panel positioning components 160 and rear plate positioning components 170 can all be provided with handles 190. Based on this, the user can complete the assembly of the top and bottom plate positioning components 140, side panel positioning components 150, door panel positioning components 160 and rear plate positioning components 170 to the workbench 120 by holding the handles 190, or disassemble them through the workbench 120, making the assembly tooling of the modular magnetic shielding cabin more convenient to use.

[0134] like Figure 14 As shown, according to a second aspect of the embodiments of this application, a method for assembling a modular magnetic shielding cabin is proposed, which is applied to the assembly fixture of the modular magnetic shielding cabin as described in any of the above technical solutions. The assembly method includes:

[0135] Step 201: Set the top and bottom plate positioning assembly on the workbench and assemble the top and bottom plates of the modular magnetic shielding cabin using the top and bottom plate positioning assembly;

[0136] Step 202: Set the side panel positioning assembly on the workbench and assemble the side panels of the modular magnetic shielding cabin using the side panel positioning assembly;

[0137] Step 203: Set the door panel positioning assembly on the workbench and assemble the door panel of the modular magnetic shielding cabin using the door panel positioning assembly;

[0138] Step 204: Set the rear panel positioning assembly on the workbench and assemble the rear panel of the modular magnetic shielding cabin using the rear panel positioning assembly;

[0139] Step 205: Assemble the top plate, bottom plate, side plates, door plates, and rear plate to obtain the modular magnetic shielding cabin.

[0140] The modular magnetic shielding cabin assembly method provided in this application embodiment, because it is applied to the assembly tooling of the modular magnetic shielding cabin as described in any of the above technical solutions, therefore the modular magnetic shielding cabin assembly method has all the beneficial effects of the above-described modular magnetic shielding cabin assembly tooling.

[0141] The modular magnetic shielding cabin assembly method provided in this application embodiment allows for the fixation of one of the top and bottom plate positioning components, side panel positioning components, door panel positioning components, and rear plate positioning components via a workbench during the assembly process. Taking one assembly sequence as an example, the top and bottom plate positioning components can be set on the workbench first to position the top and bottom plates of the magnetic shielding cabin, resulting in more precise assembly. Then, the side panel positioning components can be set on the workbench to position the side panels of the magnetic shielding cabin, resulting in more precise assembly. Next, the door panel positioning components can be set on the workbench to position the door panels of the magnetic shielding cabin, resulting in more precise assembly. Finally, the rear plate positioning components can be set on the workbench to position the rear plate of the magnetic shielding cabin, resulting in more precise assembly. Finally, the precisely assembled top plate, bottom plate, side panels, door panels, and rear plate are assembled, which makes the assembly of the modular magnetic shielding cabin more precise, ensures the consistency of the size of the splice seams of different modules, and simplifies the assembly process, thus improving the performance of the magnetic shielding room.

[0142] like Figures 8 to 10As shown, in one feasible embodiment, the side panel positioning assembly 150 is placed on the workbench 120. The steps of assembling the side panel of the modular magnetic shielding cabin using the side panel positioning assembly 150 include: positioning the frame 231 of the side panel based on the side panel frame positioning member 151 and the side panel frame limiting block 152; limiting the conductive layer 232 of the side panel based on the conductive layer limiting block 153, and connecting the conductive layer 232 of the side panel to the frame 231 of the side panel; and limiting the magnetic layer 233 of the side panel based on the magnetic layer limiting block 154, and connecting the magnetic layer 233 of the side panel to the frame 231 and / or the conductive layer 232 of the side panel.

[0143] In this technical solution, during the side panel assembly process, the side panel frame positioning pieces 151 can be first set on both sides of the workbench 120 through the second set of positioning pin holes 130, and at least two side panel frame limiting blocks 152 can be arranged in the middle of the workbench 120. In this case, a positioning gap can be formed between the two side panel frame positioning pieces 151, and the two ends of the side panel frame 231 can abut against the two side panel frame positioning pieces 151 respectively. The side panel frame limiting blocks 152 located in the middle of the workbench 120 can clamp the side panel frame 231, thereby completing the fixing of the side panel frame 231. After the side panel frame 231 is fixed, a side panel conductive layer limiting block 153 can be installed on the side panel frame positioning member 151 by inserting a shaft pin 200 into a pin hole 130. The side panel conductive layer limiting block 153 can limit the conductive layer 232 of the side panel, allowing it to be precisely assembled onto the side panel frame 231. After the conductive layer 232 is assembled, a side panel magnetic layer limiting block 154 can be inserted onto the side panel conductive layer limiting block 153 by inserting a shaft pin 200 into a pin hole 130. The magnetic layer limiting block 154 can then limit the electromagnetic layer of the side panel, completing the assembly of the electromagnetic layer. This allows for high-precision assembly of the side panel, improving its overall assembly accuracy.

[0144] Understandably, the assembly process for the top plate, bottom plate, door panel, and rear panel is basically the same as that for the side panels; the main difference lies in the placement of the specific positioning components. Based on this, a modular magnetic shielding cabin assembly fixture can be used to assemble the top plate, bottom plate, side panels, door panel, and rear panel with high precision. Then, based on these components, a modular magnetic shielding cabin can be assembled and manufactured, thus improving the precision of the modular magnetic shielding cabin.

[0145] like Figures 11 to 13As shown, in one feasible implementation, the steps of assembling the top plate, bottom plate, side plate, door plate and rear plate to obtain a modular magnetic shielding cabin include: inserting conductive components between two adjacent plates.

[0146] It is understood that the modular magnetic shielding cabin may include a top plate 210, a bottom plate 220, a side plate 230, a door plate 240, and a rear plate 250. Each of the top plate 210, bottom plate 220, side plate 230, door plate 240, and rear plate 250 may include a frame 231, a conductive layer 232, and a magnetically conductive layer 233. In addition, the modular magnetic shielding cabin may also include a conductive element 260, which is connected to two adjacent plates. Specifically, it may be connected to the conductive layer 232 of two adjacent plates. One of the two adjacent plates has an insert, one end of which is inserted into the insert, and the other end is connected to the conductive layer 232 of the other plate.

[0147] Specifically, an oblong hole can be formed on the conductive layer 232, and the conductive element 260 is connected to the conductive layer 232 of another plate through the oblong hole, which can compensate for some of the machining tolerances and installation errors. It is convenient to adjust the conductive element 260 on the conductive layer 232 and can ensure the continuity of the conductive layer 232.

[0148] like Figures 11 to 13 As shown, in some examples, the conductive element 260 can be a copper strip.

[0149] The modular magnetic shielding cabin assembly tooling and method provided in this application embodiment significantly improves efficiency compared to traditional installation methods. Traditional methods, which require four people and may take 10 days to install one cabin, only allow for single-cabin installation, demanding high worker skill levels, resulting in low efficiency and high rework rates. With the same number of workers, the modular magnetic shielding cabin assembly tooling and method provided in this application embodiment only require approximately five days. This allows for mass production, lower worker skill requirements, higher efficiency, lower rework rates, and modular interchangeability.

[0150] In one feasible implementation, the assembly method of the modular magnetic shielding cabin further includes:

[0151] The edges of the conductive layer are roughened.

[0152] Assemble the top panel, bottom panel, side panels, door panels, and rear panel, and fill the joints of the conductive layers of adjacent panels with conductive colloid.

[0153] In this technical solution, before the top plate, bottom plate, side plate, door plate, and rear plate are prepared using assembly tooling, the conductive layer of each plate can be prepared first. After the conductive layer is cut and prepared according to the expected specifications, the edge area of ​​the conductive layer can be roughened to form a rough texture. When splicing the top plate, bottom plate, side plate, door plate, and rear plate, conductive colloid can be filled at the joint between two adjacent conductive layers. Roughening the conductive layer increases its roughness, which facilitates the adhesion of the conductive colloid. The use of conductive colloid ensures the reliability of the electrical connection between the conductive layers of two adjacent plates, and further improves the shielding effect of the modular magnetic shielding cabin.
