Description

Technical Field

[0001] This utility model relates to the field of pneumatic drive and mechanical transmission technology, specifically to a pneumatically driven six-position rotating detection platform. Background Technology

[0002] According to the currently valid testing standard for electrical measuring equipment, GB / T17215.211-2021, electromagnetic radiation immunity testing is required on all six sides of the electrical measuring equipment. Each side must be rotated to the forward plane for testing, and the forward plane must be coplanar with the uniform field domain (i.e., each forward plane is 3 meters away from the electromagnetic wave transmitting antenna), and the bottom plane must be at the same height (i.e., the bottom plane is 1 meter above the ground). The changes in readings are then observed to see if they meet the national standard requirements. Currently, the switching of the six sides for this test is mostly done manually, meaning that the electromagnetic field radiation immunity testing of the six sides of the tested equipment is completed by manually switching them. This method suffers from problems such as low testing efficiency and high dependence on manual labor.

[0003] To address the shortcomings of manual inspection, automated inspection platforms have been developed. These platforms are mostly motor-driven, requiring a PLC (Programmable Logic Controller) or other controller at each station to operate the motor. When the magnetic field strength of the transmitting antenna gradually increases from 80MHz to 2GHz, its strong electromagnetic radiation interferes with the motor's control signal, causing the motor to receive incorrect commands or even shut down. Furthermore, individual actions are often directly output by the motor, lacking a robust transmission mechanism to ensure coordinated operation of the entire sequence. Achieving coordinated operation requires multi-motor control, which places higher demands on the stability and accuracy of the control system and necessitates the use of shielded motors. This significantly increases manufacturing costs and negatively impacts stability and control accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatically driven six-position rotary testing platform. It uses pneumatic drive instead of motor drive, and the transmission mechanism realizes the linkage of action groups to replace the multi-motor coordinated control, thereby realizing the six-sided switching and automatic testing of electrical measuring equipment, overcoming the defects of manual testing and automatic testing platforms in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pneumatically driven six-position rotating detection platform includes a fixed platform, a rotating mechanism, and tooling fixtures.

[0007] The swing table rotation mechanism is mounted on the fixed platform via a Z-axis cylinder;

[0008] The rotating mechanism of the swing table includes a first-layer Y-axis cylinder, a second-layer Y-axis cylinder, a rotary gear, a first rack, a second rack, a first X-axis cylinder, and a second X-axis cylinder. The central axis of the rotary gear extends along the Z-axis. The first rack and the second rack are disposed on both sides of the rotary gear and extend along the Y-axis. The first rack and the second rack are driven independently by the first X-axis cylinder and the second X-axis cylinder, respectively. The piston rod of the first-layer Y-axis cylinder is connected to the central axis of the rotary gear through a bearing. The second-layer Y-axis cylinder simultaneously drives the first X-axis cylinder and the second X-axis cylinder.

[0009] The tooling fixture is rotatably mounted on the end plane of the rotary gear away from the first layer Y-axis cylinder via an X-axis shaft component.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] Preferably, since the rotating platform mechanism needs a stable installation reference and precise Z-axis lifting to meet the requirement of a 1-meter height above the ground below the equipment during testing, it is necessary to avoid deviation or shaking during the lifting process. This utility model provides a fixed platform comprising a base frame and a plate mounted on the base frame. A Z-axis sliding joint and a Z-axis cylinder are mounted on the plate. A lifting plate is fixed to the top of the Z-axis sliding joint. The piston rod of the Z-axis cylinder is connected to the lifting plate, and the rotating platform mechanism is mounted on the lifting plate.

[0012] Preferably, since the rotary gear needs to move smoothly along the Y-axis, in order to ensure free rotation during the movement and avoid interference between the movement and rotation actions, thus ensuring transmission accuracy, this utility model also includes a first layer of Y-axis moving pairs and a Y-axis moving plate. The first layer of Y-axis moving pairs is disposed on both sides of the rotary gear and extends along the Y-axis. The first layer of Y-axis moving pairs are connected to the Y-axis moving plate, which is driven by the first layer of Y-axis cylinders. The Y-axis moving plate is connected to the central shaft of the rotary gear through bearings.

[0013] Preferably, the first X-axis cylinder and the second X-axis cylinder of this invention need to move synchronously along the Y-axis. To ensure that their movements do not interfere with each other and to guarantee the coordination and stability of the rack and pinion drive, this invention sets the height of the second-layer Y-axis cylinder to be higher than that of the first-layer Y-axis cylinder. The first X-axis cylinder and the second X-axis cylinder are respectively connected to mounting plates. Each mounting plate is guided by a second-layer Y-axis sliding joint. The second-layer Y-axis sliding joint is located on both sides of the rotary gear and extends along the Y-axis. The mounting plates on both sides are simultaneously driven by the second-layer Y-axis cylinder.

[0014] Preferably, the rack needs to move precisely along the X-axis to achieve engagement / disengagement with the rotary gear, in order to avoid gear-rack misalignment caused by misalignment. In this invention, the first rack is mounted on one side of the mounting plate via a first X-axis sliding pair, and the second rack is mounted on the other side of the mounting plate via a second X-axis sliding pair.

[0015] Preferably, since the tooling fixture needs to stably clamp the electrical measuring equipment and needs to achieve X-axis rotation to switch between top and bottom surface detection positions, while avoiding loosening or collision of the equipment during the rotation process, the present invention provides the X-axis system components including a rotary table, a column, and a rotary drive mechanism;

[0016] The rotary table is mounted on the end plane of the rotary gear away from the first Y-axis cylinder. The rotary table is located above the first rack and the second rack. Multiple columns are arranged at intervals along the X-axis on both sides of the rotary table. The column spacing is connected to the tooling fixture via a rotary drive mechanism. The tooling fixture is used to clamp electrical measuring equipment.

[0017] As a preferred embodiment, in order to accurately transmit the rotational power to the tooling fixture and achieve 90° rotation of the three workstations on the top, front, and bottom of the equipment, ensuring the accuracy of the rotation angle and the stability of the movement, the present invention provides that the rotational drive mechanism includes a rotary cylinder, a synchronous belt, and an X-axis.

[0018] An X-axis is mounted on the column, and the X-axis is connected to a tooling fixture. The piston rod of the rotary cylinder is connected to the X-axis on one of the columns via a synchronous belt.

[0019] Preferably, since gears and racks are prone to collisions, friction, or misalignment due to gaps during meshing, affecting transmission accuracy and component lifespan, this invention provides guide posts on the upper surfaces of the first and second racks, and guide grooves corresponding to the guide posts on the lower surface of the rotary table, with the guide grooves protruding from the rotary table.

[0020] Preferably, to improve the fault tolerance when the guide post and guide groove are fitted together and to prevent misalignment that could lead to guide failure, this invention features a V-shaped opening structure at both ends of the guide groove.

[0021] The pneumatically driven six-position rotary testing platform provided by this utility model has the following advantages compared with the prior art:

[0022] This invention provides a pneumatically driven six-position rotary testing platform for electrical measuring equipment. Replacing traditional motor drive with pneumatic drive significantly reduces manufacturing costs and fundamentally solves the problem of electromagnetic radiation affecting motion control. Furthermore, the use of five cylinders to rotate the six-position platform, along with its transmission mechanism enabling multi-directional rotation, movement, and flipping linkage, ensures the high accuracy and stability of the motion control system through its purely mechanical structure.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between; when a component is said to be "fixed" to another component, it can be directly fixed to the other component or it can be connected to a component in between.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a pneumatically driven six-station rotary testing platform, including a fixed platform 100, a rotary mechanism 200, and a tooling fixture 300. The platform's machine coordinate system (MCS) is a Cartesian coordinate system when facing the front of the platform, with the X-axis extending horizontally left and right (positive to the right), the Y-axis extending horizontally forward and backward (positive forward), and the Z-axis extending vertically up and down (positive upward).

[0034] To clarify the motion direction references of each component on the platform and ensure the coordinated operation of all actions (flipping, moving, rotating, lifting) to meet the equipment posture adjustment requirements during testing, this embodiment establishes a Cartesian coordinate system, clearly defining the X, Y, and Z axis motion directions. This provides a unified reference for the coordinated actions of each mechanism, ensuring the accuracy of six-sided switching and position adjustment.

[0035] The fixed platform 100 provides the moving reference plane and the rotating reference plane for the measuring table. The rotating table mechanism 200 enables six-sided switching, translation, and lifting to achieve the parameter requirements of the forward plane being coplanar with the uniform field domain and the lower plane being at the same height. The fixture 300 is used to clamp the electrical measuring equipment. Through the rotating table mechanism 200, the fixture 300 achieves coordinated movements of X-axis flipping (RX), Y-axis movement (TY), Z-axis rotation (RZ), and Z-axis lifting (TZ). Figure 3 As shown, Figure 3Image (a) shows the front (A), left (E), right (F), top (C), and bottom (D) of the electrical measuring device. Figure 3 (b) shows the back side (B) of the electrical measuring equipment. The Z-axis rotation enables the front (A), back (B), left (E), and right (F) to rotate to the four positions on the forward plane. The X-axis flip enables the top (C) and bottom (D) to rotate to the two positions on the forward plane. The Y-axis movement enables each forward plane to be coplanar with the field uniform domain (i.e., each forward plane is 3 meters away from the electromagnetic wave transmitting antenna). The Z-axis lifting and lowering enables the lower plane to be at the same height (i.e., the lower plane is 1 meter above the ground), thus completing the electromagnetic field radiation immunity detection.

[0036] In this embodiment, the fixed platform 100 needs to provide a stable reference for equipment installation and movement, enabling precise lifting and lowering of the swing table rotation mechanism and preventing platform swaying from affecting the test results during the testing process. The base frame and the flat plate are connected by tenon and mortise joints to ensure reference stability, and four Z-axis moving pairs, in conjunction with Z-axis cylinders, enable smooth lifting and lowering of the lifting plate, ensuring that the plane below the electrical measuring equipment always meets the 1-meter ground clearance requirement.

[0037] like Figure 4 and Figure 5 As shown, the swing table rotation mechanism 200 of this embodiment includes a Z-axis cylinder, a first Y-axis cylinder 209, a second Y-axis cylinder 214, a rotary gear 218, a first rack 219, a second rack 217, a first X-axis cylinder 220, and a second X-axis cylinder 211. The rotating mechanism 200 is mounted on the fixed platform 100 via a Z-axis cylinder; the central axis of the rotary gear 218 extends along the Z-axis, and the first rack 219 and the second rack 217 are located on both sides of the rotary gear 218 and extend along the Y-axis. The first rack 219 and the second rack 217 are driven independently by the first X-axis cylinder 220 and the second X-axis cylinder 211, respectively. The piston rod of the first layer Y-axis cylinder 209 is connected to the central axis of the rotary gear 218 via a bearing, and the second layer Y-axis cylinder 214 simultaneously drives the first X-axis cylinder 220 and the second X-axis cylinder 211. The tooling fixture 300 is rotatably mounted on the end plane of the rotary gear 218 away from the first layer Y-axis cylinder 209 via an X-axis shaft system component, that is, the first layer Y-axis cylinder 209 is located below the rotary gear 218, and the tooling fixture 300 is located above the rotary gear 218.

[0038] In this embodiment, the testing platform is raised and lowered using a Z-axis cylinder, maintaining the electrical measuring equipment at a height of 1 meter above the ground during six-sided switching testing. A fixture 300 is used to mount the electrical measuring equipment. After the fixture 300 is mounted via an X-axis shaft system, the electrical measuring equipment can rotate around the X-axis, thereby allowing testing of its top and bottom surfaces. Furthermore, the first rack 219 and the second rack 217 are engaged and disengaged from the rotary gear 218 via the first X-axis cylinder 220 and the second X-axis cylinder 211, respectively. When either the first rack 219 or the second rack 217 is engaged with the rotary gear 218, and the other rack is disengaged, the rotary gear 218 is driven to move along the Y-axis by the first layer of Y-axis cylinder 209 and rotates through engagement with the rack, causing the fixture 300 mounted on the rotary gear 218 to rotate synchronously, thus enabling testing of the left and right sides of the electrical measuring equipment. Additionally, when the first rack 219 or the second rack 217 meshes with the rotary gear 218, and the other rack disengages from the rotary gear 218, the first rack 219 and the second rack 217 are driven to move along the Y direction by the second layer Y-axis cylinder 214. The rotary gear 218 rotates by meshing with the rack. At this time, the rotary gear 218 rotates 180° without changing the position of the central axis, thereby inspecting the back of the electrical measuring equipment.

[0039] Specifically, the fixed platform 100 in this embodiment includes a base frame 101 and a flat plate 102 mounted on the base frame 101. The base frame 101 and the flat plate 102 are connected by mortise and tenon joints, and the flat plate 102 is fixed in place. Four Z-axis sliding joints 201 and a Z-axis cylinder are mounted on the flat plate 102. A lifting plate 202 is fixed to the top of the Z-axis sliding joints 201. The piston rod of the Z-axis cylinder is connected to the lifting plate 202 to drive the lifting plate 202 to achieve Z-axis lifting. The lifting plate 202 is used to install the swing table rotation mechanism 200 to keep the electrical measuring equipment at a height of 1 meter above the ground when switching between six sides for testing.

[0040] This embodiment also includes a first-layer Y-axis sliding joint 212 and a Y-axis sliding plate 203. There are two first-layer Y-axis sliding joints 212, which are respectively disposed on both sides of the rotary gear 218 and extend along the Y direction. The two first-layer Y-axis sliding joints 212 are connected to the Y-axis sliding plate 203. The Y-axis sliding plate 203 is driven by a first-layer Y-axis cylinder 209. The first-layer Y-axis cylinder 209 controls the Y-axis sliding plate 203 to move on the first-layer Y-axis sliding joint 212. The Y-axis sliding plate 203 is connected to the central shaft of the rotary gear 218 through a bearing, so as to drive the rotary gear 218 to move along the Y-axis while allowing the rotary gear 218 to rotate.

[0041] In this embodiment, the second-layer Y-axis cylinder 214 is higher than the first-layer Y-axis cylinder 209 and has four second-layer Y-axis sliding joints 210. These four joints are located on both sides of the rotary gear 218 and extend along the Y-axis. Each side of the second-layer Y-axis sliding joint 210 is connected to a mounting plate. The first X-axis sliding joint and the second X-axis sliding joint 216 are each connected to a mounting plate on one side. Specifically, the first X-axis sliding joint is connected to the first mounting plate 204, and the second X-axis sliding joint 216 is connected to the second mounting plate 213. Both the first and second mounting plates 204 and 213 are simultaneously driven by the second-layer Y-axis cylinder 214. In this embodiment, the piston rod of the second-layer Y-axis cylinder 214 is connected to a cylinder connector 215, which is simultaneously fixed to both the first and second mounting plates 204 and 213, thereby achieving simultaneous driving of both the first and second mounting plates 204 and 213.

[0042] The first X-axis cylinder 220 and the second X-axis cylinder 211 are respectively mounted on the first mounting plate 204 and the second mounting plate 213. In order to achieve rotation in different directions, the first rack 219 and the second rack 217 in this embodiment are driven by the independent first X-axis cylinder 220 and the second X-axis cylinder 211. Under the drive of the first X-axis cylinder 220 and the second X-axis cylinder 211, the first rack 219 and the second rack 217 perform X-axis linear motion on the first X-axis sliding pair and the second X-axis sliding pair 216 respectively, so as to achieve engagement and disengagement with the rotary gear 218.

[0043] Specifically, the X-axis system components of this embodiment include a rotary table 205, columns 208, and a rotary drive mechanism, wherein the rotary drive mechanism includes a rotary cylinder 206, a synchronous belt 207, and an X-axis. The rotary table 205 is mounted on the end plane (i.e., the upper end plane) of the rotary gear 218 away from the first Y-axis cylinder 209. The rotary table 205 is located above the first rack 219 and the second rack 217, and is spaced apart from the first rack 219 and the second rack 217. In this embodiment, there are two columns 208, which are spaced apart along the X-axis on the rotary table 205. Within the interval of the columns 208, a tooling fixture 300 is movably connected via the rotary drive mechanism. The tooling fixture 300 is used to clamp electrical measuring equipment.

[0044] For the rotary drive mechanism, in this embodiment, each column is equipped with its own X-axis, which is directly connected to the tooling fixture 300. The piston rod of the rotary cylinder 206 is connected to the X-axis on one of the columns 208 through the synchronous belt 207, thereby driving the X-axis to rotate. The rotary cylinder 206 can be installed on the rotary table 205.

[0045] In this embodiment, the rotating platform mechanism 200 uses multiple cylinders and a rack and pinion transmission to achieve coordinated movements such as Z-axis rotation and Y-axis movement, replacing multi-motor collaborative control, avoiding electromagnetic radiation interference, and ensuring motion accuracy. Its five cylinders, in conjunction with the rack and pinion transmission, achieve multi-action linkage without motor drive, completely avoiding electromagnetic radiation interference with the control signal; the guides of each moving pair ensure precise movements, high transmission efficiency, and strong stability.

[0046] In this embodiment, the tooling fixture 300 includes an X-direction flange 301, a mounting plate bracket 302, and a mounting plate 303. There are two X-direction flanges 301, each connected to a corresponding X-direction axis. The mounting plate bracket 302 is mounted on the X-direction flange 301, and the mounting plate 303 is fixed on the mounting plate bracket 302. The distance between the X-direction axis and the rotary table 205 is at least greater than half the length of the tooling fixture 300. This ensures that after the X-direction axis is connected to the middle of the long axis of the tooling fixture 300, the tooling fixture 300 will not collide with the rotary table 205 when rotating along the X-direction axis.

[0047] This embodiment of the fixture 300 is compatible with clamping various specifications of electrical measuring equipment, preventing equipment displacement during testing due to loose clamping, and ensuring no collision when the X-axis is rotated. Its combination structure of the X-axis flange, mounting plate bracket, and mounting plate achieves stable equipment clamping; the reasonable distance between the X-axis and the rotary table avoids collisions during rotation, and it is compatible with various commonly used equipment specifications.

[0048] Because rack and pinion meshing requires an appropriate clearance (to prevent jamming), this clearance can cause collisions and friction between the teeth when the rack moves towards the gear, leading to wear or even misalignment. Therefore, in this embodiment, a guide post 222 is provided at the middle position of the upper surface of the rack (first rack 219 and second rack 217), and a guide groove 221 is provided on the lower surface of the rotary table 205. To avoid the guide post 222 and guide groove 221 affecting the rotation of the rotary table 205, this embodiment selects a guide groove 221 that protrudes from the surface of the rotary table 205, and the initial and final positions of the guide post 222 are outside the guide groove 221, ensuring that the rotation of the rotary table 205 is not affected when the guide post 222 is at the initial and final positions. The initial position is the position where the rack and gear mesh (or disengage), and the final position is the position where the rack and gear disengage (or mesh). Furthermore, in this embodiment, the guide groove 221 has a V-shaped opening structure on both sides, increasing the fault tolerance and providing precise guidance in the middle section to ensure that the rack and gear complete a precise fit.

[0049] like Figure 6 As shown, this embodiment uses Figure 6 The position where the rack and rotary gear 218 separate, as shown in (a) in the diagram, is the initial position of the guide post 222's movement. Figure 6Image (b) shows the guide post 222 and guide groove 221 in a limiting fit state. Figure 6 Taking the meshing position of the rack and rotary gear 218 shown in (c) as an example, which is the end position of the guide post 222's movement, it can be seen that when the guide post 222 is in the initial and end positions, it is located outside the guide groove 221, and the rotary gear 218 rotates without interference between the rotary table 205 and the guide post 222. If it is necessary to switch the rack and rotary gear 218 from the disengaged state to the engaged state, the corresponding X-axis cylinder drives the rack from... Figure 6 The position shown in (a) is moved to Figure 6 Position (c) is shown in the diagram; if it is necessary to switch the rack and rotary gear 218 from the meshing state to the disengaged state, the corresponding X-axis cylinder will drive the rack from... Figure 6 The position shown in (c) is moved to Figure 6 The position shown in (a) is shown in the image.

[0050] In this embodiment, the guide post and guide groove work together to solve the problems of collisions and misalignments caused by gear and rack meshing gaps, which affect transmission accuracy and component lifespan, and the guide structure must not interfere with the rotation of the rotary table. Through the precise fit between the guide post and guide groove, the rack movement is guided during engagement / disengagement, reducing collisions and friction. The initial / end point of the guide post is outside the guide groove, avoiding interference with the rotary table rotation, extending component lifespan and ensuring transmission accuracy. Furthermore, the ingenious design of the V-shaped opening guide groove solves the problem of guide failure caused by misalignment between the guide post and guide groove, affecting the gear and rack meshing accuracy. The V-shaped opening structure improves the alignment tolerance, and the precise guidance in the middle section ensures that the gear and rack are always precisely meshed, reducing the risk of alignment deviation.

[0051] The working process of this utility model is as follows:

[0052] In general, the electrical measuring equipment is fixed on the tooling fixture 300, which can accommodate various commonly used specifications of the electrical measuring equipment. The front A (digital display meter reading page) of the electrical measuring equipment is defined as the initial position. At this time, the front A is the forward plane, and the lower plane is 1 meter above the ground. This forward plane is coplanar with the electromagnetic field uniform domain. Electromagnetic field radiation immunity is tested on the first detection surface of the electrical measuring equipment. The cylinder is controlled in sequence to adjust the remaining surfaces of the electrical measuring equipment to be coplanar with the radio frequency electromagnetic field uniform domain and at the same height as the lower plane. Electromagnetic field radiation immunity is then tested on each detection surface.

[0053] Specifically, during testing, the front side (A) of the electrical measuring equipment is placed opposite the RF transmitting antenna at a distance of approximately 3 meters. Voltage and load need to be applied to ensure its normal operation. According to the pre-planned action sequence, the front side (A) of the electrical measuring equipment is tested first. At this point, the forward plane is the front side (A) of the electrical measuring equipment (initial position), which is coplanar with the field uniformity domain (this plane also serves as the calibration reference plane for the subsequent planes). Then, the electromagnetic field radiation immunity test begins. After the front side (A) is completed, the Y-axis movement and Z-axis rotation mechanism are linked to sequentially complete the cyclic switching of front side (A), right side (F), front side (A), left side (E), and front side (A), realizing three-position (front side (A), right side (F), and left side (E)) testing.

[0054] The specific operation is as follows: In the initial position, the front of the electrical measuring device on the fixture 300 is coplanar with the field uniformity region. The second rack 217 is set to mesh with the rotary gear 218, and the first rack 219 is disengaged from the rotary gear 218. The Y-axis moving plate 203 moves a fixed distance along the positive Y-axis. At the same time, due to the meshing of the rack and gear, the rotary gear 218 drives the rotary table 205 to rotate 90°, and the fixture 300 mounted on the rotary table 205 also rotates 90°, completing the linkage. At this time, the right side of the electrical measuring device on the fixture becomes a forward plane, coplanar with the field uniformity region. When the Y-axis moving plate 203 moves back in the negative Y-axis direction, the fixture 300 mounted on the rotary table 205 also returns to the initial position, at which point the front of the electrical measuring device on the fixture becomes a forward plane. Then, the first rack 219 meshes with the rotary gear 218, the second rack 217 separates from the rotary gear 218, the Y-axis moving plate 203 moves a fixed distance along the positive Y-axis, and the tooling fixture 300 mounted on the rotary table 205 also rotates 90°. At this time, the left side of the power measuring device on the tooling fixture 300 becomes the forward plane. When the Y-axis moving plate 203 moves back along the negative Y-axis, the tooling fixture 300 mounted on the rotary table 205 returns to its initial position. At this time, the front of the power measuring device on the fixture becomes the forward plane.

[0055] Then, the Z-axis rotation mechanism is activated, thereby realizing the cyclic switching between front A and back B, and completing the inspection of one station on back B.

[0056] The specific operation is as follows: Following the initial position of the previous workstation, the second-layer Y-axis cylinder 214, through the cylinder connector 215, pushes the first mounting plate 204 and the second mounting plate 213 to move simultaneously in the negative Y-axis direction. At this time, the first rack 219 separates from the rotary gear 218, and the second rack 217 meshes with the rotary gear 218. The second rack 217 moves a fixed distance in the negative Y-axis direction along with the second mounting plate 213. The rotary gear 218 rotates 180° in place. At this time, the back surface B of the power-on measuring device on the tooling fixture 300 becomes a forward plane and is coplanar with the field uniformity region. After the detection is completed, the second-layer Y-axis cylinder 214 resets, and the rotary gear 218 rotates 180° again. At this time, the front surface of the power-on measuring device on the tooling fixture 300 returns to its initial position, completing the reset. It should be noted that, since the rotary gear 218 needs to rotate 180° in place when inspecting the back side, during the switching process, the first X-axis cylinder 220 can also drive the first rack 219 from... Figure 6 As shown in (a), it is in the separated state from the rotary gear 218 and moves to... Figure 6 As shown in (c), the second rack 217 is engaged with the rotary gear 218 and driven by the second X-axis cylinder 211 from... Figure 6 As shown in (c), it is in the meshing state with the rotary gear 218 and moves to... Figure 6 The state shown in (a) is separated from the rotary gear 218.

[0057] Finally, the X-axis flipping mechanism is activated, sequentially switching between top surface C, front surface A, bottom surface D, and front surface A to complete the inspection of the two workstations, top surface C and bottom surface D.

[0058] The specific operation is as follows: Following the initial position of the previous workstation, the front surface A of the electrical measuring equipment on the fixture 300 is coplanar with the uniform field region. The rotary cylinder 206, via the synchronous belt 207, drives the fixture 300 mounted on the column 208 to rotate. The rotary cylinder has a three-position rotation function: 90° forward rotation, centering, and 90° reverse rotation. Therefore, the top surface C and bottom surface D of the electrical measuring equipment mounted on the fixture 300 can be sequentially rotated 90° to the forward plane, coplanar with the uniform field region. Then, through the action of the Z-axis lifting mechanism, the height above the ground is moved to 1 meter, completing the inspection of the top surface C and bottom surface D workstations. Finally, it is reset to the initial position. This completes the inspection of all six workstations of the electrical measuring equipment.
