Description

Technical Field

[0001] This invention relates to a portable internal wiring error detection device for switchgear, belonging to the field of power system equipment technology. Background Technology

[0002] Switchgear is an electrical device used in power systems for opening, closing, controlling, and protecting circuits during power generation, transmission, distribution, and energy conversion. It integrates components such as busbars, load switches, disconnect switches, contactors, relays, voltmeters, ammeters, and instrument transformers. During the assembly, operation, maintenance, and on-site quality inspection of switchgear, the correctness of the internal circuit wiring directly affects the normal operation of the equipment and the safety and stability of the power system. Problems such as incorrect wiring, missing connections, loose connections, or abnormal wiring positions can lead to minor issues like equipment failure to start or control logic malfunction, or more serious issues such as short circuits, equipment damage, or even safety accidents. Currently, various technical solutions exist for switchgear wiring testing.

[0003] Patent CN114924212A discloses an automatic detection device and method for wiring in a power distribution cabinet. The device employs a main unit and multiple detection modules that cooperate with the units to be detected on the power distribution cabinet. Each detection module is connected to a detection control module and communicates with the main unit via cables. Each detection module includes multiple detection probes connected to the parts of the power distribution cabinet to be tested. The detection control module controls the continuity between the detection probes. The main unit detects the continuity between the detection probes by sending power line carrier detection signals, thereby determining whether the wiring is correct. This solution uses a contact-based electrical signal detection method, requiring each wire connection to be checked individually with probes, resulting in low detection efficiency. Furthermore, the detection fixture needs to be customized for different power distribution cabinets, leading to poor compatibility with different types of switchgear. Additionally, the device lacks portability, cannot meet the on-site testing needs of outdoor switchgear and other dispersed deployment scenarios, and cannot correct detected wiring errors.

[0004] Patent CN117901130A discloses a wiring robot for testing electrical parameters of switchgear, including an electrical parameter testing platform, wiring fixtures, a wiring robotic arm, and an RGV chassis. The RGV chassis holds the switchgear to be tested. The wiring fixture includes an outgoing wire connector mechanism and an incoming wire connector mechanism. The testing cables from the electrical parameter testing platform connect to the outgoing wire connector mechanism, and the testing cables from the incoming wire connector mechanism connect to the switchgear. The wiring robotic arm is positioned next to the wiring fixture and automatically connects the testing cables to the outgoing and incoming wire connector mechanisms, thus achieving unmanned automatic testing of the switchgear's electrical parameters. However, this solution uses an RGV chassis and a ground rail mechanism, resulting in a fixed overall structure that cannot be easily moved. Its robotic arm is mainly used to connect the plugs and sockets of the testing cables and lacks image recognition error detection capabilities, making it unable to determine if the wiring is correct. The entire device relies on a track for operation, making it difficult to meet the testing needs of switchgear in different locations under complex outdoor working conditions.

[0005] Patent CN219496535U discloses an automatic electrical wiring detection device based on machine recognition, including a housing, an industrial computer, a battery, a telescopic bracket, and a camera. The industrial computer is embedded in the housing, and its upper surface is equipped with a display screen. The battery is installed in the housing for power supply. The housing has a first groove for housing the telescopic bracket, one end of which is hinged to the first groove, and the camera is detachably connected to the other end of the telescopic bracket. This solution uses the camera to capture images of electrical cabinet wiring, and the industrial computer performs image recognition to determine whether the wiring is correct. The housing structure is also easy to carry. However, the telescopic bracket of this device can only achieve height adjustment in one direction and cannot make large-scale precise position adjustments in the horizontal and forward / backward directions. When the telescopic bracket extends a large distance, it lacks an auxiliary support mechanism, which can easily cause sagging deformation, affecting the positioning accuracy of image acquisition. In addition, the device only has a detection function and cannot correct incorrect wiring, still requiring manual intervention for rework.

[0006] Patent CN206982692U discloses an auxiliary wiring robot for on-site verification of instrument transformers in substations. It includes a wiring system and a positioning system, with the wiring system mounted on the positioning system. The wiring system comprises a wiring device, a buffer device, a monitoring device, and a wiring robot arm. The positioning system consists of two sets of Cartesian coordinate robots, including an X-axis robot arm, a Y-axis robot arm, and a Z-axis robot arm, enabling three-dimensional position adjustment. The wiring device includes a clamping mechanism, a ball screw mechanism, and a gear transmission mechanism for clamping the wiring ports of the instrument transformer to be verified. While this solution possesses three-dimensional position adjustment capabilities and robot operation functions, its overall structure is fixed and mounted on a base plate, lacking portability. Its application scenario is auxiliary wiring for on-site verification of instrument transformers, not error detection in switchgear internal wiring. The monitoring camera on this device is only used for assisting precise positioning and lacks image recognition and automatic error detection functions, making it unable to determine whether the wiring is correct, let alone correct incorrect wiring.

[0007] In summary, existing wiring detection solutions either employ contact-based electrical signal detection, which is inefficient and has poor adaptability; or they are fixed structures that lack portability; or they have limited position adjustment functions, making it difficult to achieve precise positioning in multiple directions; and all of them only have detection functions and cannot correct incorrect wiring. Summary of the Invention

[0008] Purpose of the invention: To address the shortcomings of existing technologies, this invention provides a portable wiring error detection device for switch cabinets. This invention enables portable operation through a mobile chassis, achieves precise three-dimensional positioning through the coordinated use of lifting, moving, and telescopic mechanisms, and integrates automatic wiring error detection and correction with an image acquisition module and clamping components.

[0009] Technical solution: A portable switch cabinet internal wiring error detection device, comprising a movable chassis, a lifting mechanism, a moving mechanism, a telescopic mechanism, an image acquisition module, and a clamping component, all electrically connected to the control module. The lifting mechanism is vertically mounted on the movable chassis, the moving mechanism is horizontally slidably mounted on the lifting mechanism, and the telescopic mechanism is slidably mounted on the moving mechanism in a direction perpendicular to both the lifting and moving mechanisms. The clamping assembly is mounted at the end of the telescopic mechanism, the image acquisition module is mounted at the end of the telescopic mechanism away from the clamping assembly, and the control module is mounted on the movable chassis. The lifting mechanism drives the moving mechanism to reciprocate vertically, the moving mechanism drives the telescopic mechanism to reciprocate horizontally, and the telescopic mechanism extends and retracts in a direction perpendicular to both the lifting and moving mechanisms. The control module determines whether there is a wiring error based on the image information acquired by the image acquisition module. When a wiring error is found, the control module controls the lifting mechanism, the moving mechanism and the telescopic mechanism to move together to move the clamping component to the target position of the incorrect wiring, and the clamping component adjusts or corrects the wiring.

[0010] This invention achieves overall portability and mobility of the device by setting up a movable chassis. A lifting mechanism, a moving mechanism, and a telescopic mechanism work together to achieve precise three-dimensional positioning of the detection device along the vertical Z-axis, horizontal X-axis, and front-back Y-axis. Simultaneously, an image acquisition module captures images of the wiring area, which are then identified and analyzed by the control module. When a wiring error is detected, the control module coordinates the movement of each mechanism to move the clamping component to the target position for wiring correction. This integrates wiring detection and correction functions, solving the technical problem in existing technologies where detection devices cannot simultaneously meet the requirements of portability, multi-dimensional precise positioning, and integrated wiring error detection and correction.

[0011] In a preferred embodiment, to counteract the downward load exerted on the moving mechanism by the telescopic mechanism, an anti-sag mechanism is provided between the lifting mechanism and the telescopic mechanism. The telescopic mechanism is slidably connected to the moving mechanism via a sliding connecting platform. One end of the anti-sag mechanism is movably connected to the lifting mechanism, and the other end is movably connected to the sliding connecting platform of the telescopic mechanism.

[0012] By setting an anti-sag mechanism between the lifting mechanism and the telescopic mechanism, the anti-sag mechanism extends synchronously when the moving mechanism drives the telescopic mechanism to slide in the horizontal direction, and applies an upward compensating tension to the sliding connection platform of the telescopic mechanism to counteract the downward pressure exerted on the moving mechanism by the weight of the telescopic mechanism through its end. This reduces the bending deformation of the moving mechanism caused by bearing the load of the telescopic mechanism, and improves the structural rigidity and posture stability of the detection device when the telescopic mechanism extends to its maximum stroke.

[0013] In a preferred embodiment, to ensure the smooth operation of the anti-sag mechanism during movement and to avoid motion interference, the anti-sag mechanism includes a first mounting base, a second mounting base, and a gas strut. The first mounting base is mounted on the lifting mechanism, the second mounting base is mounted on the sliding connection platform of the telescopic mechanism, and the two ends of the gas strut are hinged to the first mounting base and the second mounting base, respectively.

[0014] By setting the anti-sag mechanism as a structure consisting of a first mounting base, a second mounting base, and a gas strut, and connecting the two ends of the gas strut to the first and second mounting bases respectively via hinges, the gas strut can extend and retract synchronously with the sliding connection platform when the moving mechanism drives the telescopic mechanism to slide in the horizontal direction. During the extension and retraction process, the axis angle of the gas strut is adaptively adjusted through the hinges, avoiding motion interference or off-center loading caused by changes in the angle between the mounting bases, and ensuring stable compensation support and smooth operation of the anti-sag mechanism throughout the entire stroke range of the device.

[0015] In a preferred embodiment, in order to achieve reliable clamping and operation of the wire by the clamping assembly, the clamping assembly includes a clamping hand, a first driving part, and a mounting plate. The mounting plate is installed at the end of the telescopic mechanism, the clamping hand is installed on the mounting plate, and the first driving part is installed inside the clamping hand and is drively connected to the clamping hand.

[0016] By configuring the clamping assembly into a structure consisting of a clamping hand, a first driving unit, and a mounting plate, the first driving unit drives the clamping hand to perform opening and closing actions, and the mounting plate acts as a connecting medium to install the clamping assembly at the end of the telescopic mechanism, so that the clamping hand can accurately reach the target wiring position and perform clamping operations under the drive of the telescopic mechanism.

[0017] In a preferred embodiment, to achieve precise alignment of the gripper's posture at the target wiring position, a rotating mechanism is also included on the mounting plate. The bottom of the gripper is rotatably connected to the rotating mechanism, and the rotating mechanism is signal-connected to the control module.

[0018] By setting a rotating mechanism on the mounting plate and rotatably connecting the bottom of the gripper to the rotating mechanism, the image acquisition module acquires image information of the target wiring area. Then, the control module controls the rotating mechanism to drive the gripper to rotate and make fine-tuning of the angle based on the relative angle between the gripper and the target wiring in the image information, so as to achieve precise alignment between the gripper and the target wiring.

[0019] In a preferred embodiment, to precisely control the travel distance of the gripper when it is inserted into the switch cabinet and to prevent hard collisions with the target wiring terminals, a distance sensor mounted on the mounting plate is also included, the distance sensor being signal-connected to the control module.

[0020] By setting a distance sensor on the mounting plate, the distance sensor detects the distance between the front end of the gripper and the target wiring position in real time and feeds the distance information back to the control module, so as to realize precise distance control and positioning judgment of the gripper as it approaches the target position.

[0021] In a preferred embodiment, to provide early warning and prevent collisions with the internal structure of the cabinet during the wiring process of the clamping hand, a collision sensor and a spring buffer are also included. The spring buffer is installed between the clamping hand and the rotating mechanism, and the collision sensor is installed on the front end face of the clamping hand. The collision sensor is signal-connected to the control module.

[0022] By setting up a collision sensor and a spring buffer as a supplementary protection mechanism for the ranging sensor, the collision sensor is installed on the front end face of the gripper, and the spring buffer is installed between the gripper and the rotating mechanism. When a collision occurs, the collision sensor feeds back a signal to the control module to prevent the detection device from moving further. At the same time, the spring buffer is compressed to buffer further collisions between the gripper and the switch cabinet, thus achieving dual collision protection from both signal feedback and motion buffering levels.

[0023] In a preferred embodiment, to prevent the wire terminals from being crushed or broken due to excessive clamping force during the clamping process, a pressure sensor is also included, which is connected to the control module via a signal connection.

[0024] By setting a pressure sensor on the clamping surface of the clamping hand to detect the clamping force in real time and feeding the pressure signal back to the control module, the control module controls the clamping force of the clamping hand according to the preset pressure threshold, thereby realizing adaptive clamping force control for wires of different specifications.

[0025] In a preferred embodiment, to improve the image acquisition quality of the image acquisition module under complex lighting conditions such as the switch cabinet being located outdoors, insufficient lighting, or low illuminance inside the cabinet, a supplementary light is installed on the mounting plate facing the switch cabinet, and the supplementary light is signal-connected to the control module.

[0026] By installing supplementary lights on the mounting panel and pointing them towards the switch cabinet, the supplementary lights provide auxiliary lighting for the image acquisition area, improving the brightness and clarity of the acquired images, and enhancing the accuracy and stability of wiring identification.

[0027] In a preferred embodiment, to enable the detection device to move flexibly and be stably supported in different working conditions indoors and outdoors, the bottom of the mobile chassis is provided with multiple brakeable swivel wheels and anchor bolts respectively located at the front and rear ends of the bottom of the mobile chassis; the brakeable swivel wheels and anchor bolts are configured to selectively achieve three-point support, wherein the two rear brakeable swivel wheels are locked and the front anchor bolts are adjusted to contact the ground to form support, or the two front brakeable swivel wheels are locked and the rear anchor bolts are adjusted to contact the ground to form support.

[0028] The device can move in different directions by installing multiple brakeable casters on the bottom of the mobile chassis. Anchor bolts are installed at the front and rear of the chassis bottom. The brakeable casters can drive the error detection device to move in different directions to meet the testing needs of switch cabinets in different indoor or outdoor locations. The anchor bolts can support, level, and adjust the height of the error detection device to adapt to the usage requirements under different testing conditions. The brakeable casters and anchor bolts are configured to selectively achieve three-point support, thereby balancing the device's portability and stability during the testing process.

[0029] Beneficial Effects: This invention achieves overall portability and mobility of the device by setting up a movable chassis. The coordinated operation of the lifting, moving, and telescopic mechanisms enables precise three-dimensional positioning of the detection device in vertical, horizontal, and longitudinal directions. The detection range can be significantly adjusted to adapt to the structural dimensions and wiring area differences of various types of switchgear, effectively solving the problem of poor adaptability of existing fixed or single-dimensional adjustment devices. Simultaneously, this invention integrates wiring detection and correction functions. An image acquisition module captures images of the wiring area, which are then identified and analyzed by the control module. This enables automatic detection and location of incorrect wiring. When a wiring error is detected, the coordinated movement of the various mechanisms moves the clamping component to the target position for wiring correction. Compared to existing devices that only have detection functions, this invention improves the automation level and efficiency of switchgear wiring error detection and correction. Furthermore, this invention improves the device's posture stability during large-stroke extension by setting a follow-up anti-sag mechanism between the lifting mechanism and the telescopic mechanism, applying compensating tension to the sliding connection of the telescopic mechanism, effectively offsetting the downward load generated by the telescopic mechanism's own weight on the moving mechanism; it also achieves precise positioning control by setting a distance sensor, and forms a dual collision protection mechanism with a collision sensor and spring buffer; it achieves adaptive clamping force control by setting a pressure sensor on the clamping surface, and ensures image acquisition quality under complex lighting conditions with a supplementary light. All these improvements comprehensively enhance the operational safety and reliability of the detection device in complex outdoor and cabinet environments, meeting the actual needs of switchgear wiring error detection and correction under different indoor and outdoor working conditions.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this 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 this invention.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] like Figure 1 As shown, a portable switch cabinet internal wiring error detection device includes a movable chassis 2, a lifting mechanism 3, a moving mechanism 4, a telescopic mechanism 5, an image acquisition module 6, and a clamping assembly 7, all electrically connected to the control module 1. The lifting mechanism 3 is vertically mounted on the movable chassis 2. The moving mechanism 4 is horizontally slidably mounted on the lifting mechanism 3. The telescopic mechanism 5 is slidably mounted on the moving mechanism 4 in a direction perpendicular to both the lifting mechanism 3 and the moving mechanism 4. The clamping assembly 7 is mounted at the end of the telescopic mechanism 5. The image acquisition module 6 is mounted at the end of the telescopic mechanism 5 away from the clamping assembly 7. The control module 1 is mounted on the movable chassis 2. The lifting mechanism 3 drives the moving mechanism 4 to reciprocate vertically. The moving mechanism 4 drives the telescopic mechanism 5 to reciprocate horizontally. The telescopic mechanism 5 extends and retracts in a direction perpendicular to both the lifting mechanism 3 and the moving mechanism 4. The control module 1 determines whether there is a wiring error based on the image information acquired by the image acquisition module 6. When a wiring error is found, the control module 1 controls the lifting mechanism 3, the moving mechanism 4 and the telescopic mechanism 5 to move together to move the clamping component 7 to the target incorrect wiring position, and the clamping component 7 adjusts or corrects the wiring.

[0036] The device is made portable by setting up a movable chassis 2. The lifting mechanism 3, the moving mechanism 4, and the telescopic mechanism 5 work together to achieve precise three-dimensional positioning of the detection device in the vertical Z-axis, the horizontal X-axis, and the front-back Y-axis. At the same time, the image acquisition module 6 acquires images of the wiring area and the control module 1 identifies and analyzes them. When a wiring error is detected, the control module moves the clamping component 7 to the target position to correct the wiring. This achieves the integrated function of wiring detection and correction, solving the technical problem that the detection device in the prior art cannot simultaneously meet the requirements of portable movement, multi-dimensional precise positioning, and integrated wiring error detection and correction.

[0037] like Figure 2 As shown, in this embodiment, both the lifting mechanism 3 and the moving mechanism 4 include a motor and a lead screw guide structure 31. The end of the moving mechanism 4 is slidably connected to the lead screw guide structure 31 of the lifting mechanism 3 through a sliding connection platform 9, i.e., a slider. The end of the telescopic mechanism 5 is slidably connected to the lead screw guide structure 31 of the moving mechanism 4 through a sliding connection platform 9, i.e., a slider. like Figure 4As shown, the telescopic mechanism 5 includes a telescopic cylinder 51, a scissor-type telescopic linkage 52, a fixed plate 53, a movable plate 54, a lead screw guide rail 55, and a front end plate 56. The fixed plate 53 is installed at the front end of the telescopic cylinder 51. The telescopic end of the telescopic cylinder 51 passes through the fixed plate 53 and is connected to the movable plate 54. The other side of the movable plate 54 is connected to the front end plate 56 via the lead screw guide rail 55. The other side of the front end plate 56 is connected to the mounting plate 73. When the telescopic cylinder 51 extends or retracts, the movable plate 54 moves along its axial direction, driving the lead screw guide rail 55 and its front end plate 56 to move. The distance between the movable plate 54 and the front end plate 56 increases or decreases, thereby driving the clamping assembly 7 to move. At the same time, the scissor-type linkage mechanism 52 supports the front end plate 56 and extends and retracts synchronously with the telescopic direction, thereby driving the clamping assembly 7.

[0038] The control module 1 is equipped with a touch screen display for real-time display of test results, wiring position information and related parameter settings; In the event of a wiring error, the control module 1 controls the lifting mechanism 3, the moving mechanism 4, and the telescopic mechanism 5 to move in coordination, adjusting the position of the gripper 71 in the vertical, horizontal, and forward / backward directions, respectively, so that it moves to the vicinity of the target wiring error location, so as to carry out subsequent wiring adjustment or correction operations.

[0039] like Figure 3 As shown, in order to counteract the downward load applied to the moving mechanism 4 by the telescopic mechanism 5, an anti-sag mechanism 8 is provided between the lifting mechanism 3 and the telescopic mechanism 5. The telescopic mechanism 5 is slidably connected to the moving mechanism 4 through a sliding connection platform 9. One end of the anti-sag mechanism 8 is movably connected to the lifting mechanism 3, and the other end is movably connected to the sliding connection platform 9 of the telescopic mechanism 5.

[0040] By setting an anti-sag mechanism 8 between the lifting mechanism 3 and the telescopic mechanism 5, the anti-sag mechanism 8 extends synchronously when the moving mechanism 4 drives the telescopic mechanism 5 to slide in the horizontal direction, and applies an upward compensating pull to the sliding connection platform 9 of the telescopic mechanism 5, i.e. the slider, to counteract the downward pressure exerted on the moving mechanism 4 by the weight of the telescopic mechanism 5 through its end, thereby reducing the bending deformation of the moving mechanism 4 caused by bearing the load of the telescopic mechanism 5, and improving the posture stability of the detection device when the telescopic mechanism 5 extends to its maximum stroke.

[0041] To ensure the smooth operation of the anti-sag mechanism 8 during movement and to avoid motion interference, the anti-sag mechanism 8 includes a first mounting base 81, a second mounting base 82, and a gas strut 83. The first mounting base 81 is mounted on the lifting mechanism 3, and the second mounting base 82 is mounted on the sliding connection platform 9 of the telescopic mechanism 5. The two ends of the gas strut 83 are respectively hinged to the first mounting base 81 and the second mounting base 82.

[0042] By setting the anti-sag mechanism 8 as a structure consisting of a first mounting base 81, a second mounting base 82, and a gas strut 83, and connecting both ends of the gas strut 83 to the first mounting base 81 and the second mounting base 82 respectively via hinges, the gas strut 83 can extend and retract synchronously with the sliding connection 9 when the moving mechanism 4 drives the telescopic mechanism 5 to slide in the horizontal direction. During the extension and retraction process, the axis angle of the gas strut 83 is adaptively adjusted through hinges to avoid motion interference or off-center loading caused by changes in the angle between the mounting bases, thus ensuring the stable compensation support and smooth operation of the anti-sag mechanism 8 throughout the entire stroke range of the device.

[0043] The ball joint is used for hinge connection. The ball joint allows the gas strut 83 to rotate as the angle between the two mounting supports changes during the extension or retraction process, thereby compensating for the angular deviation generated during the movement, avoiding motion interference between the gas strut 83 and the lifting mechanism 3 or the moving mechanism 4, and ensuring smooth operation.

[0044] like Figure 6 As shown, in order to achieve reliable clamping and operation of the connector by clamping assembly 7, clamping assembly 7 includes clamping hand 71, first drive unit 72, and mounting plate 73. The mounting plate 73 is installed at the end of telescopic mechanism 5, clamping hand 71 is installed on mounting plate 73, and first drive unit 72 is installed inside clamping hand 71 and is connected to clamping hand 71 in a transmission manner.

[0045] By configuring the clamping assembly 7 into a structure consisting of a clamping hand 71, a first drive unit 72, and a mounting plate 73, the first drive unit 72 drives the clamping hand 71 to perform opening and closing actions, and the mounting plate 73 serves as a connecting intermediary to install the clamping assembly 7 onto the end of the telescopic mechanism 5, so that the clamping hand 71 can accurately reach the target wiring position and perform clamping operations under the drive of the telescopic mechanism 5.

[0046] like Figure 7 As shown, in this embodiment, the gripper 71 includes a mounting base 711 and gripping parts 712 arranged opposite to each other. Each gripping part 712 is hinged to the mounting base 711 by a connecting rod 713. The connecting rods 713 of the two gripping parts 712 are respectively provided with meshing teeth that mesh with each other. Any connecting rod 713 is provided with a through hole 7131 along the axial direction. A first drive motor 714 is installed inside the gripper 71. The drive shaft of the first drive motor 714 is connected to the through hole 7131 of any connecting rod 713. After the first drive motor 714 rotates, the two connecting rods 713 begin to mesh and drive, so that the two gripping parts 712 approach or move away from each other.

[0047] like Figure 4 and Figure 6As shown, in order to achieve precise matching of the posture of the gripper 71 at the target wiring position, a rotating mechanism 10 is also provided on the mounting plate 73. The bottom of the gripper 71 is rotatably connected to the rotating mechanism 10, and the rotating mechanism 10 is signal connected to the control module 1.

[0048] By setting a rotating mechanism 10 on the mounting plate 73 and rotatably connecting the bottom of the gripper 71 to the rotating mechanism 10, after the image acquisition module 6 acquires image information of the target wiring area, the control module 1 controls the rotating mechanism 10 to drive the gripper 71 to rotate for fine-tuning of the angle based on the relative angle between the gripper 71 and the target wiring in the image information, thereby achieving precise alignment between the gripper 71 and the target wiring. In this embodiment, the rotating mechanism 10 includes a rotating disk 101 and a second drive motor 102. The rotating disk 101 and the second drive motor 102 are connected in a transmission manner, and the rotating disk 101 drives the gripper 71 to rotate.

[0049] like Figure 6 As shown, in order to accurately control the travel distance of the gripper 71 when it is inserted into the switch cabinet and to prevent hard collision with the target wiring terminal, a distance sensor 11 is also included, which is mounted on the mounting plate 73 and is signal-connected to the control module 1.

[0050] By setting a distance sensor 11 on the mounting plate 73, the distance sensor 11 can detect the distance between the front end of the gripper 71 and the target wiring position in real time and feed the distance information back to the control module 1, so as to realize precise distance control and positioning judgment of the gripper 71 as it approaches the target position.

[0051] To provide early warning and prevent collisions with the cabinet structure during the wiring process of the clamping hand 71, a collision sensor 12 and a spring buffer 13 are also included. The spring buffer 13 is installed between the clamping hand 71 and the rotating mechanism 10, and the collision sensor 12 is installed on the front end face of the clamping hand 71. The collision sensor 12 is signal-connected to the control module 1.

[0052] By setting a collision sensor 12 and a spring buffer 13 as a supplementary protection mechanism for the ranging sensor 11, the collision sensor 12 is installed on the front end face of the gripper 71, and the spring buffer 13 is installed between the gripper 71 and the rotating mechanism 10. When a collision occurs, the collision sensor 12 feeds back a signal to the control module 1 to prevent the detection device from moving further. At the same time, the spring buffer 13 is compressed to buffer further collisions between the gripper 71 and the switch cabinet, thus achieving dual collision protection from both signal feedback and motion buffering levels.

[0053] To prevent the wire from being crushed or broken due to excessive clamping force during the clamping process of the clamping hand 71, a pressure sensor 14 is also included, which is installed on the clamping surface of the clamping hand 71 and is connected to the control module 1.

[0054] By setting a pressure sensor 14 on the clamping surface of the clamping hand 71 to detect the clamping force in real time and feeding the pressure signal back to the control module 1, the control module 1 controls the clamping force of the clamping hand 71 according to the preset pressure threshold, thereby realizing adaptive clamping force control for wires of different specifications.

[0055] In order to improve the image acquisition quality of the image acquisition module 6 under complex lighting conditions such as the switch cabinet being located outdoors, insufficient light, or low illuminance inside the cabinet, a supplementary light 15 facing the switch cabinet is installed on the mounting plate 73, and the supplementary light 15 is connected to the control module 1 via signal.

[0056] By setting up a supplementary light 15 on the mounting plate 73 and pointing it toward the switch cabinet, the supplementary light 15 provides auxiliary lighting for the image acquisition area, improving the brightness and clarity of the acquired image, and enhancing the accuracy and stability of wiring identification.
