Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meter calibration, and in particular to a calibration device and a control method. Background Art

[0002] In modern industrial production, inserting the probe of the calibration device into the device to be calibrated is a key step. During this process, the probe needs to accurately and stably enter the port of the device to be calibrated to ensure the reliability of the test results. However, in actual operation, the probe will be affected by various interference forces during the insertion process, such as port damping, mechanical vibration, etc. These interference forces may cause unstable probe insertion or detection errors.

[0003] In order to overcome these interference forces, the existing technology usually uses a drive cylinder to push the probe. The drive cylinder can provide continuous and stable force during the probe insertion process, thereby ensuring the accurate insertion of the probe. However, in order to provide sufficient force to counteract the interference force, a high-power cylinder needs to be used. This not only increases the cost of the equipment, but more importantly, high-power cylinders are usually large in size and take up valuable space, which is particularly prominent in space-constrained application scenarios. Summary of the invention

[0004] The main purpose of the present invention is to provide a verification device and a control method, which can save space inside the verification device.

[0005] To achieve the above objectives, some embodiments of the present invention provide a verification device, comprising: Base, A probe row is slidably connected to the base along a first direction, the probe row includes probes arranged along a second direction, the second direction intersects the first direction, and the probes are used to be inserted into the device to be tested; A first driving assembly connected to the probe row and used to drive the probe row to move relative to the base along a first direction so that the probe row switches between a testing position and a position to be tested, wherein the probe is suitable for being inserted into a device to be tested at the testing position; A limit assembly connected to the base, the limit assembly is configured to be in a locked state and an unlocked state, in which the limit assembly is connected to the probe row to limit the movement of the probe row along the first direction, and in the unlocked state, the limit assembly is spaced from the probe row to enable the probe row to move along the first direction; Among them, at the verification position, the limit assembly is in a locked state.

[0006] In some embodiments, the limiting assembly includes a first limiting structure. In a locked state, the first limiting structure moves along the second direction to limit the probe row from moving along the first direction.

[0007] In some embodiments, the probe row is provided with a limiting hole, the axis of the limiting hole is parallel to the second direction, and in the locked state, the first limiting structure is inserted into the limiting hole.

[0008] In some embodiments, the limiting assembly also includes a second limiting structure. Along the second direction, the first limiting structure and the second limiting structure are relatively arranged on both sides of the probe row. In the locked state, the first limiting structure and the second limiting structure both move toward the probe row along the second direction to limit the movement of the probe row along the first direction.

[0009] In some embodiments, the first driving assembly is disposed at one side of the probe row along the first direction.

[0010] In some embodiments, along the second direction, the verification device includes two first driving assemblies that are symmetrically arranged.

[0011] In some embodiments, the first drive assembly includes a drive motor.

[0012] In some embodiments, the base is provided with slide grooves arranged opposite to each other along the second direction, and both ends of the probe row are arranged in the slide grooves along the second direction.

[0013] In some embodiments, the testing device further includes a second driving component, the second driving component is connected to the base, and the second driving component is suitable for driving the base to move along the first direction.

[0014] An embodiment of a second aspect of the present application provides a control method for a calibration device according to any of the above embodiments. The control method includes: The first driving assembly drives the probe row to move to the verification position; The limit assembly locks the probe row in the verification position; The second driving component drives the testing device to move along the first direction so that the probe is inserted into the device to be tested.

[0015] According to the above embodiments, the beneficial effects of the present invention are: The calibration device of the present application includes a base, a probe row, a first drive assembly and a limit assembly. The base serves as the basic structure of the entire device, providing an installation platform and a supporting function. The probe row is slidably connected to the base along a first direction, and the probe row includes probes arranged along a second direction, the second direction and the first direction intersect, and the probes are used to insert the device to be calibrated. The first drive assembly is connected to the probe row, and is used to drive the probe row to move relative to the base along the first direction, so that the probe row switches between the calibration position and the position to be calibrated. At the calibration position, the probe is suitable for inserting the device to be calibrated. The limit assembly is connected to the base, and the limit assembly is configured to be a locked state and an unlocked state. In the locked state, the limit assembly is connected to the probe row to limit the movement of the probe row along the first direction. In the unlocked state, the limit assembly and the probe row are spaced apart so that the probe row can move along the first direction. At the calibration position, the limit assembly is in a locked state.

[0016] It is understandable that when the probe row is inserted into the port of the device to be tested, it is usually necessary to overcome a certain damping. The source of the damping may be the clamping force of the device to be tested to stabilize the plug-in effect of the probe row, or it may be due to the accumulation of mud and other debris at the port of the device to be tested, which causes the port diameter to be reduced. If the cylinder maintains a constant force to push the probe row in the first direction, when the probe row contacts the port of the device to be tested, the cylinder needs to overcome the resistance encountered by the probe row at this time in order to successfully push the probes of the probe row into the port of the device to be tested. However, the size of these resistances is uncontrollable, so it is necessary to preset a cylinder with sufficient power to ensure that the probe row can be successfully inserted into the port of the device to be tested every time. However, high-power cylinders have a large volume, and these cylinders appear very cramped in a compact testing device.

[0017] The present application designs a limit assembly to lock the probe row at the calibration position. After the probe row is subjected to the resistance of the device to be tested, the first drive assembly used to push the probe row does not need to do work on these resistances. The present application uses the limit assembly to bear these resistances. However, the limit assembly is connected to the base and moves with the base. The structure that provides the driving force for the base can be arranged on the outside of the calibration device housing and will not affect the space inside the calibration device. In summary, the first drive assembly inside the calibration device can be set to a smaller power, and only the probe row needs to be pushed to the position to be tested. There is no need to do work on the resistance encountered when the subsequent probe is inserted into the device to be tested. The first drive assembly with a smaller power has a smaller volume, so the present application can greatly save the internal space of the calibration device.

[0018] In addition, the addition of the limit assembly can save energy consumption of the device, that is, the first drive assembly does not need to overcome the resistance when inserting the device to be tested, and the first drive assembly does not need to work all the time to maintain the probe row in the testing position.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] In the related art, during the verification process of the electric energy meter, it is crucial to ensure that the detection probe can be accurately inserted into the interface of the electric energy meter to be tested. Due to differences in the design and manufacturing of the electric energy meter, as well as wear or dirt accumulation that may occur after long-term use, these factors may cause certain damping or resistance inside the interface. Therefore, in the process of inserting the probe into the electric energy meter, various forms of interference forces may be encountered, which will increase the difficulty of insertion and affect the smooth progress of the verification process. In order to overcome the above problems, the prior art usually uses a driving cylinder to provide the necessary thrust to ensure that the probe can be stably and reliably docked with the interface of the electric energy meter. However, when selecting a driving cylinder for such an application, its power must be considered. For situations where it is necessary to counteract large interference forces, high-power cylinders are usually selected because they can provide sufficient force to ensure successful insertion of the probe, even in the face of high damping or other obstacles. However, high-power cylinders are often accompanied by large volume and weight, which not only increases the overall size of the equipment, but also leads to inefficient space utilization, especially for compact devices such as verification devices.

[0028] Reference below Figures 1 to 7 The detection device and control method according to the embodiment of the present invention are described.

[0029] Reference Figures 1 to 5In some embodiments, the calibration device includes a base 100, a probe row 200, a first drive assembly 300 and a limit assembly 400. The base 100 serves as the basic structure of the entire device, providing a mounting platform and a support function. The probe row 200 is fixed to the base 100 by a sliding connection, and can move relative to the base 100 along a first direction (usually a linear direction). The probe row 200 contains a plurality of probes 210 arranged along a second direction, and the second direction intersects with the first direction. These probes 210 are used to be inserted into the device to be calibrated for detection or calibration.

[0030] The sliding connection between the probe row 200 and the base 100 can be achieved by a guide rail system to ensure that the probe row 200 can move smoothly along a predetermined path. The first drive assembly 300 is connected to the probe row 200 and is responsible for providing power so that the probe row 200 can switch between the test position and the position to be tested. When the probe row 200 is in the test position, the probes 210 thereon will be accurately inserted into the device to be tested; while in the position to be tested, the probe row 200 is in a ready state but no device is inserted.

[0031] The limit assembly 400 is connected to the base 100, and the limit assembly 400 can be configured in two states: a locked state and an unlocked state. In the locked state, the limit assembly 400 will establish a mechanical connection with the probe row 200, limit the movement of the probe row 200 along the first direction, and ensure that the probe row 200 remains stable and motionless during the calibration process; in the unlocked state, the limit assembly 400 will be separated from the probe row 200, allowing the probe row 200 to move freely along the first direction. In particular, at the calibration position, in order to ensure the test accuracy, the limit assembly 400 is always kept in a locked state to prevent unnecessary displacement of the probe row 200.

[0032] Through the above structural design, the calibration device can not only maintain high accuracy and stability when performing calibration, but also simplify the operating process and improve work efficiency.

[0033] Regarding the "unnecessary displacement" in the foregoing content, it can be understood that when the probe row 200 is inserted into the port of the device to be tested, it is usually necessary to overcome a certain damping. The source of the damping may be the tightening force of the device to be tested in order to stabilize the plug-in effect of the probe row 200, or it may be due to the accumulation of mud and other debris at the port of the device to be tested, which causes the port diameter of the device to be tested to be reduced. If the cylinder maintains a constant force to push the probe row 200 in the first direction, when the probe row 200 contacts the port of the device to be tested, the cylinder needs to overcome the resistance to the probe row 200 at this time, so that the probe 210 of the probe row 200 can be smoothly pushed into the port of the device to be tested. However, the size of these resistances is uncontrollable, so it is necessary to preset a cylinder with sufficient power to ensure that the probe row 200 can be smoothly inserted into the port of the device to be tested every time. However, high-power cylinders have a large volume, and these cylinders appear very cramped in a compact testing device. The present application designs a limit assembly 400 to lock the probe row 200 at the calibration position. After the probe row 200 is subjected to the resistance of the device to be tested, the first drive assembly 300 used to push the probe row 200 does not need to do work on these resistances, and the limit assembly 400 bears these resistances. However, the limit assembly 400 is connected to the base 100 and moves with the base 100. The structure that provides the driving force for the base 100 can be arranged outside the housing of the calibration device, and will not affect the space inside the calibration device. In summary, the first drive assembly 300 inside the calibration device can be set to a smaller power, and only the probe row 200 needs to be pushed to the position to be tested, without the need to do work on the resistance received when the subsequent probe 210 is inserted into the device to be tested. The first drive assembly 300 with a smaller power has a smaller volume, so the present application can greatly save the internal space of the calibration device.

[0034] In addition, through the design of the detection device of the present application, not only can a first drive component 300 with lower power, i.e., a smaller volume, be set, thereby saving space inside the test device, but the addition of the position limiting component 400 can save energy consumption of the device, i.e., the first drive component 300 does not need to overcome the resistance when inserting the device to be tested, and the first drive component 300 does not need to work all the time to maintain the state where the probe row 200 is located at the test position.

[0035] It is understandable that in some embodiments, from the perspective of material selection, the limit assembly 400 can be made of high-strength metal alloys, such as stainless steel or aluminum alloys. Such materials have good wear resistance and corrosion resistance and can effectively extend the service life. On the other hand, considering the requirements of the degree of automation, the limit assembly 400 can also be equipped with an electromagnetic lock mechanism, that is, electromagnetic force is used to achieve fast and reliable locking and unlocking actions. In this case, a coil is provided inside the limit assembly 400. When the current passes through the coil to generate a magnetic field, it can attract or repel iron parts, thereby changing the state of the limit assembly 400. In addition, in order to further improve safety, sensors can be integrated on the limit assembly 400 to monitor its working status in real time and feed back information to the control system so that a timely response can be made.

[0036] Regarding the first drive assembly 300, in some embodiments, it includes a motor plus a lead screw transmission method, a hydraulic cylinder or a pneumatic cylinder as a power source. The hydraulic / pneumatic system provides greater power and is easier to accurately control, which is suitable for handling large loads. For the probe row 200, in order to improve the positioning accuracy, a precision ball bearing can be installed at its bottom, which reduces the friction resistance and also enhances the smoothness of sliding.

[0037] In some embodiments, in order to facilitate user operation and maintenance, the size of the calibration device should be as compact as possible, the layout of each part should be reasonable, and all interfaces and adjustment knobs should be easily accessible to ensure that various tasks can be completed smoothly even in a small space. Such a design not only optimizes the user experience, but also helps to reduce long-term operating costs.

[0038] Reference Figure 2 In some embodiments, the limiting assembly 400 includes a first limiting structure 410. When the limiting assembly 400 enters a locked state, the first limiting structure 410 can move in a second direction (perpendicular to the first direction) to limit the movement of the probe row 200 in the first direction. Specifically, when the position of the probe row 200 needs to be fixed, the first limiting structure 410 will move laterally and contact the probe row 200, thereby preventing any displacement thereof in the first direction. This design ensures that the probe row 200 is absolutely stationary at the calibration position, thereby improving the stability and accuracy during the detection process.

[0039] It is understandable that, in some embodiments, the working principle and structure of the first limiting structure 410 can have a variety of variations. For example, the first limiting structure 410 is a mechanical limiting structure, specifically, the first limiting structure 410 can be a simple mechanical locking pin or claw mechanism, which is controlled by a manual or electric driver to move laterally. When the probe row 200 needs to be locked, the driver pushes the locking pin or claw to extend so that it is embedded in a specific hole or other matching feature on the probe row 200 to form an effective block. This method is simple and reliable and is suitable for most conventional application scenarios. In some embodiments, the first limiting structure 410 can also be an electromagnetic limiting structure, specifically, a small electromagnetic coil is provided inside the first limiting structure 410, and a magnetic force is generated when an electric current passes through the coil to attract or repel a movable iron core. This iron core directly or indirectly contacts the probe row 200, and the locking or unlocking function is realized by the action of electromagnetic force. The advantages of the electromagnetic type are fast response speed, high control accuracy, and the locking force can be adjusted according to actual needs.

[0040] In some embodiments, in order to enhance the reliability and safety of the system, an additional safety switch or sensor is provided near the first limiting structure 410 to monitor the limiting state and provide instant feedback to the control system. This not only improves the intelligence level of the system, but also provides additional safety protection for operators. At the same time, in order to adapt to different usage environments and technical requirements, the dimensions and installation methods of the first limiting structure 410 can also be flexibly adjusted to ensure optimal space utilization and installation convenience.

[0041] Reference Figure 1 and Figure 2 In some embodiments, the probe row 200 is provided with a limiting hole, and the axis of the limiting hole is parallel to the second direction. When the limiting assembly 400 is in a locked state, the first limiting structure 410 moves along the second direction and is inserted into the limiting hole on the probe row 200. This design ensures that the probe row 200 is firmly fixed in the calibration position to prevent any unnecessary movement along the first direction. Specifically, the cooperation between the limiting hole and the first limiting structure 410 can provide a mechanical barrier so that the probe row 200 will not be easily displaced even if it is affected by external vibration or other interference forces.

[0042] In some embodiments, the size and shape of each limiting hole matches the first limiting structure 410 to ensure a good plugging effect.

[0043] In some embodiments, the first limiting structure 410 can be in the form of a pin, a locking tongue, etc., which can move linearly along the second direction under the action of a driving mechanism (such as a cylinder or an electric push rod). When the probe row 200 needs to be locked, the first limiting structure 410 will be pushed into the corresponding limiting hole; in the unlocked state, it will withdraw from the limiting hole, allowing the probe row 200 to slide freely. By inserting the first limiting structure 410 into the limiting hole, a mechanical constraint is formed to prevent the probe row 200 from moving along the first direction. This is because the wall surface of the limiting hole provides sufficient friction and support to resist any force that attempts to move the probe row 200 along the first direction. In addition, since the axis of the limiting hole is parallel to the second direction, the insertion action of the first limiting structure 410 will not affect the position accuracy of the probe row 200 along the second direction, thereby ensuring the stability of the entire system. This design not only improves the stability and accuracy during verification, but also simplifies the operation process. A reliable locking function can be achieved through a simple mechanical plug-in action, reducing the need for a complex control system, reducing costs and improving reliability.

[0044] It is understandable that in some embodiments, in order to adapt to different application scenarios and technical requirements, the design of the limiting hole and the first limiting structure 410 can be more diversified. For example, in some embodiments, the limiting hole and the first limiting structure 410 can be made of different materials according to the actual working environment, such as wear-resistant steel, aluminum alloy, etc., to improve durability and corrosion resistance.

[0045] In some embodiments, the cross-sectional shape of the limiting hole and the first limiting structure 410 can be expanded from a circle to a rectangle, an ellipse, or other forms to meet specific installation space limitations or requirements for enhancing locking strength.

[0046] In some embodiments, in situations where the degree of automation is high, the solenoid valve can be used to control the cylinder or the motor-driven actuator to automatically complete the insertion and extraction of the limit structure, further improving work efficiency.

[0047] In some embodiments, in order to increase safety, multiple limiting holes can be set at different positions of the probe row 200, and multiple groups of first limiting structures 410 can be provided to form a multiple redundant protection mechanism to ensure that even if individual components fail, it will not affect the overall locking effect.

[0048] Reference Figure 2 and Figure 3In some embodiments, the limiting assembly 400 further includes a second limiting structure 420, and the first limiting structure 410 and the second limiting structure 420 are arranged relatively on both sides of the probe row 200 along the second direction. In the locked state, the two limiting structures both move toward the probe row 200 along the second direction, and work together to limit the movement of the probe row 200 along the first direction. This double-sided limiting design increases the safety and reliability of locking, especially when subjected to a large external force, and can more effectively keep the position of the probe row 200 unchanged.

[0049] In some embodiments, specifically, the first limiting structure 410 and the second limiting structure 420 may have similar structures, but are located on both sides of the probe row 200, and a certain distance is maintained between them. The limiting structures on each side can operate independently, but will move inwards at the same time in the locked state until they contact the surface of the probe row 200 and are inserted into the corresponding limiting holes (if any).

[0050] In some embodiments, in order to ensure the consistency of the movement of the limiting structures on both sides, the same driving source (such as a bidirectional cylinder or a dual-output motor) can be used to synchronously drive the two, thereby avoiding the problem of tilting or deformation of the probe row 200 due to uneven force on one side.

[0051] When the first limiting structure 410 and the second limiting structure 420 move in the second direction at the same time and contact the probe row 200, they will generate a pair of forces in opposite directions on both sides of the probe row 200, which cancel each other out, thereby effectively suppressing any potential movement trend of the probe row 200 along the first direction. In addition, since the two limiting structures apply pressure from both sides at the same time, the load can be better distributed, the local stress concentration phenomenon can be reduced, and the service life of the device can be extended. Even if the limiting structure on one side fails, the other side can still continue to function, providing additional safety protection for the user. At the same time, such a design is also conducive to coping with more complex usage conditions, such as large external force impacts or frequent operation requirements.

[0052] It is understandable that in some embodiments, in order to adapt to different application scenarios and technical requirements, the design of the first limiting structure 410 and the second limiting structure 420 can have a variety of variations. For example, the first limiting structure 410 and the second limiting structure 420 can be designed as a progressive locking method, that is, the limiting structure on one side initially contacts the probe row 200, and then the other side gradually follows up, and finally reaches a completely locked state. This method helps to make a smooth transition and avoid damage caused by sudden excessive pressure.

[0053] In some embodiments, sensors are used to monitor the contact force between the limiting structures on both sides and the probe row 200 to achieve adaptive adjustment and ensure the best locking effect without damaging the probe row 200 .

[0054] In some embodiments, the first limiting structure 410 and the second limiting structure 420 are designed as replaceable modular components for easy maintenance and upgrading. Different types of limiting structures can be flexibly combined and used according to actual needs, thereby improving the versatility and flexibility of the device.

[0055] In some embodiments, an intelligent feedback system is integrated to monitor the working status of the limit structure in real time and transmit the information to the control system so that a timely response can be made, further improving the intelligence level of the system and the user experience.

[0056] Reference Figure 2 and Figure 4 , in some embodiments, the first drive assembly 300 is arranged on one side of the probe row 200 along the first direction. This layout ensures that the first drive assembly 300 can effectively transmit power to the probe row 200, so that it can smoothly switch between the calibration position and the position to be verified. Specifically, the first drive assembly 300 is arranged in the direction directly behind or directly in front of the probe row 200 along the first direction, and provides a thrust or a pull force to the probe row 200 so that the probe row 200 moves smoothly along the first direction. Compared with the first drive assembly 300 being arranged on the opposite sides of the probe row 200 along the second direction, the probe row 200 is driven to move along the first direction as a whole by driving the two ends of the probe row 200 along the second direction. Since the probe row 200 has a length along the second direction, when the first drive assembly 300 is arranged at the two ends of the probe row 200 along the second direction, it is easy to produce a situation where the two ends of the probe row 200 along the second direction move asynchronously. The driving force provided by the first drive assembly 300 of the present application is concentrated in the middle of the probe row 200, which is conducive to smoothly pushing the probe row 200 to move.

[0057] The sliding connection between the base 100 and the probe row 200 can be realized in various ways, such as direct mechanical connection (such as gears, racks), flexible connection (such as belt drive) or linear guide system, etc. These connection methods ensure the high efficiency and stability of power transmission.

[0058] In some embodiments, the calibration device is provided with only one first drive assembly. When the first drive assembly 300 is working, the driving force generated by it acts on the probe row 200 along the first direction, pushing the probe row 200 to move relative to the base 100. Since the first drive assembly 300 is only located on one side, the force generated by it is unidirectional, but with the help of the slide groove 110 or other guide devices on the base 100, the probe row 200 can be accurately moved along the predetermined track to ensure that it can reach the correct calibration position or the position to be calibrated every time.

[0059] It is understandable that in some embodiments, the first drive assembly 300 can be designed as a modular unit, allowing different types of drives (such as motors, cylinders) to be replaced according to actual needs. This flexibility provides users with more choices and also facilitates later maintenance and upgrades.

[0060] In some embodiments, a position sensor or encoder is integrated inside the first driving assembly 300 to monitor the position information of the probe row 200 in real time and feed it back to the control system for precise control, which helps to improve positioning accuracy and ensure that each operation can achieve the expected effect.

[0061] In some embodiments, in order to increase the fault tolerance of the system, a spare first drive assembly 300 may be provided on the other side of the probe row 200 and on the opposite side of the probe row 200 along the first direction. Although usually only one main drive assembly is working, when the main drive assembly fails, the spare assembly can immediately take over the task to ensure continuous operation.

[0062] In some embodiments, to address the problem of overheating due to long-term operation, a cooling device such as a heat sink or a fan may be added around the first drive component 300 to extend the life of the device and maintain stable performance.

[0063] Reference Figure 4 In some embodiments, the first driving assembly 300 is connected to one side of the probe row 200 along the first direction, and along the second direction, the verification device includes two first driving assemblies 300 arranged symmetrically. This symmetrical layout allows the probe row 200 to move more smoothly along the first direction under the action of driving forces evenly distributed on both sides. Each first driving assembly 300 has the same specifications and functions, and they are located on both sides of the two ends of the probe row 200, respectively, to ensure balanced distribution of force.

[0064] In some embodiments, in order to ensure the consistency of the movements of the two first drive assemblies 300, the same controller can be used to coordinate their work. The controller can issue instructions according to a preset program to start, accelerate, decelerate, and stop the two drive assemblies at the same time, ensuring that the probe row 200 always moves along a straight path.

[0065] The two first drive components 300 arranged symmetrically not only enhance the stability and reliability of the system, but also improve the safety and accuracy of the operation. Even if one of the drive components fails, the other can still continue to work, providing additional safety for the user. In addition, the symmetrical design also helps to simplify the design of the control system and reduce development costs.

[0066] It is understood that in some embodiments, each first drive assembly 300 can be equipped with an independent controller, allowing them to adjust their respective output power and speed according to actual conditions. This flexibility can better cope with special needs under non-standard working conditions.

[0067] In some embodiments, an intelligent algorithm is introduced to detect the difference between the two first driving assemblies 300 in real time, and automatically perform compensation adjustment to ensure that the probe row 200 always maintains an optimal motion state.

[0068] In some embodiments, a universal interface is designed so that first drive components 300 of different models can be easily interchanged, thereby improving the compatibility and scalability of the device.

[0069] In some embodiments, by the coordinated work between the symmetrically arranged first drive components 300, energy consumption can be minimized while meeting the load requirements, thereby achieving the goal of green energy saving.

[0070] Reference Figure 4 In some embodiments, the first driving assembly 300 includes a driving motor. The driving motor is the core power source for realizing the movement of the probe row 200 along the first direction. The driving motor converts the rotational motion into the linear motion through the transmission mechanism (such as a gear, a rack or a belt), thereby driving the probe row 200 to switch between the testing position and the position to be tested relative to the base 100.

[0071] In some embodiments, the drive motor can be a stepper motor, a servo motor, or a brushless DC motor, and the specific choice depends on the application requirements. For example, a stepper motor is suitable for applications that require high-precision positioning, while a servo motor is suitable for scenarios with high speed and torque requirements.

[0072] In some embodiments, the driving motor is fixedly mounted on one side of the base 100 and maintains a direct or indirect mechanical connection with the probe row 200. To ensure stability and reliability, the motor should be firmly fixed on the supporting structure, and its output shaft should be precisely aligned with the transmission component.

[0073] When the drive motor receives the control signal, it generates a rotational motion and transmits it to the probe row 200 through the transmission mechanism. For a stepper motor, each pulse signal causes the motor to rotate a fixed angle, thereby driving the probe row 200 to move a short distance in the first direction. This step-by-step advancement method can achieve very precise position control. For a servo motor, it can continuously adjust the speed and torque to adapt to different load conditions, ensuring that the probe row 200 can reach the target position smoothly and quickly.

[0074] The use of a drive motor as the first drive component 300 not only provides a strong driving force, but also has good controllability and response speed. They can reduce energy consumption and extend service life while ensuring high efficiency. In addition, the motor can also be integrated with an encoder or other feedback device to monitor its own working status in real time, further improving the automation level and safety of the system.

[0075] It is understandable that in some embodiments, in order to improve the fault tolerance of the system, a backup drive motor can also be provided on the other side of the probe row 200. Although usually only one main motor is working, when the main motor fails, the backup motor can immediately take over the task to ensure continuous operation.

[0076] In some embodiments, a PID algorithm or a fuzzy logic controller is used to optimize the performance parameters of the motor, such as start-up time, acceleration curve, and stopping accuracy, etc. This helps to improve the operating efficiency of the entire system and the user experience.

[0077] In some embodiments, a universal interface is designed so that drive motors of different models can be easily interchanged, thereby improving the compatibility and scalability of the device. At the same time, this modular design is also conducive to later maintenance and upgrades.

[0078] In some embodiments, by optimizing the power management and speed regulation strategy of the drive motor, energy consumption can be minimized while meeting the load requirements, achieving the goal of green energy saving. For example, a frequency converter is used to adjust the speed of the motor so that it only provides maximum power when necessary and is in low power consumption mode the rest of the time.

[0079] Reference Figure 2 In some embodiments, the base 100 is provided with slide grooves 110 arranged opposite to each other along the second direction, and both ends of the probe row 200 are arranged in the slide grooves 110 along the second direction. This design ensures that the probe row 200 can remain stable and straight when moving along the first direction, avoiding detection errors caused by tilt or offset.

[0080] In some embodiments, the slide groove 110 is located on the base 100 and extends along the second direction, and its shape and size match the guide members at both ends of the probe row 200. The inner surface of the slide groove 110 is smooth, which reduces friction resistance and facilitates smooth sliding of the probe row 200. In order to enhance wear resistance and corrosion resistance, the slide groove 110 can be made of special materials or surface treated.

[0081] In some embodiments, both ends of the probe row 200 are equipped with guides, which are embedded in and closely fit with the slide groove 110. The guides can be rollers, sliders, etc., which not only play a guiding role, but also can withstand a certain lateral force to prevent the probe row 200 from shaking.

[0082] When the probe row 200 is subjected to the force from the first driving assembly 300, it moves in the first direction, and the guides at both ends of the probe row 200 slide synchronously in the slide groove 110. Due to the close fit between the slide groove 110 and the guide, the probe row 200 can only move along the predetermined path without lateral displacement. This constraint mechanism ensures the straightness and stability of the probe row 200 throughout the entire stroke, thereby improving the accuracy of the detection result.

[0083] By providing the slide groove 110 on the base 100 and embedding the two ends of the probe row 200 therein, the freedom of the probe row 200 can be effectively limited to ensure that it moves accurately along the first direction. Such a design not only improves the stability of the system, but also simplifies the mechanical structure and reduces the difficulty of assembly. In addition, the presence of the slide groove 110 also provides additional support for the probe row 200, reducing the wear problem that may occur during long-term use.

[0084] It is understood that in some embodiments, a self-lubricating coating or a solid lubricant is added to the inside of the slideway 110 to reduce friction resistance and extend the service life. This is particularly important for frequently used calibration devices because it can significantly reduce maintenance frequency and costs.

[0085] In some embodiments, an elastic buffer device, such as a rubber pad or a spring, is provided at the end of the slide slot 110 to absorb the impact force generated when the probe row 200 reaches the limit position and protect the mechanical parts from damage, which helps to improve the durability and safety of the system.

[0086] In some embodiments, for large or multi-station testing devices, multiple sets of parallel slots 110 can be provided on the base 100 to allow multiple probe rows 200 to work simultaneously. Appropriate spacing is maintained between each set of slots 110 to ensure that each probe row 200 operates independently without interfering with each other.

[0087] In some embodiments, the slideway 110 is manufactured using a high-precision processing technology to ensure that its straightness and flatness meet strict standards, which can further improve the movement accuracy of the probe row 200 and meet the requirements of high-end detection tasks.

[0088] In some embodiments, the testing device further comprises a second driving assembly connected to the base 100 and adapted to drive the base 100 to move along the first direction. This design enables the entire testing device to be adjusted in a wider range to accommodate testing devices of different sizes or positions.

[0089] In some embodiments, the second drive assembly is located at one end or side of the base 100. The second drive assembly can use a variety of transmission methods to achieve the movement of the base 100, such as a ball screw, belt drive, or gear rack, etc. These transmission methods can not only provide sufficient driving force, but also ensure stability and accuracy during the movement process.

[0090] When the second drive component receives the control signal, it will start and generate a thrust or pull along the first direction to act on the base 100. Since the base 100 itself has a large mass and needs to overcome frictional resistance, the second drive component must have a higher output power and torque. After the probe row 200 moves to the calibration position along the first direction, the base 100 is driven to move by the second drive component to accurately insert the probe row 200 into the device to be tested. Of course, it is understandable that the driving work of the second drive component and the first drive component 300 can be carried out simultaneously, and the two do not affect each other. It is only necessary to ensure that the probe row 200 is locked by the limit assembly 400 at the moment when the probe row 200 is inserted into the terminal of the device to be tested, and cannot move in the first direction.

[0091] The introduction of the second drive assembly not only expands the working range of the verification device, but also improves its flexibility and adaptability. By precisely controlling the position of the base 100, it can be ensured that each inspection can target a specific target area, thereby improving inspection efficiency and accuracy. In addition, this design also helps to simplify the operation process, reduce the need for manual intervention, and further improve the automation level of the system.

[0092] It is understood that in some embodiments, the second drive assembly can be designed as a modular unit, allowing different types of drives (such as motors, cylinders) to be replaced according to actual needs. This flexibility provides users with more choices and also facilitates later maintenance and upgrades.

[0093] In some embodiments, a position sensor or encoder is integrated inside the second drive assembly to monitor the position information of the base 100 in real time and feed it back to the control system for precise control, which helps to improve positioning accuracy and ensure that each operation can achieve the expected effect.

[0094] In some embodiments, in order to increase the fault tolerance of the system, a spare second drive assembly can also be provided on the other side of the base 100. Although usually only one main drive assembly is working, when the main drive assembly fails, the spare assembly can immediately take over the task to ensure continuous operation.

[0095] Reference Figure 6 The embodiment of the second aspect of the present application provides a control method. In some embodiments, the control method for the detection device of any of the above embodiments includes the following steps: S101: The first driving assembly 300 drives the probe row 200 to move to a testing position; S103: The limiting assembly 400 locks the probe row 200 at the verification position; S105: The second driving assembly drives the testing device to move along the first direction so that the probe 210 is inserted into the device to be tested.

[0096] Regarding the first driving assembly 300 driving the probe row 200 to move to the verification position, specifically, the first driving assembly 300 is started after receiving the instruction, and the probe row 200 is moved from the to-be-verified position to the verification position along the first direction through the transmission mechanism. During this process, the limit assembly 400 is in an unlocked state, allowing the probe row 200 to slide freely.

[0097] Regarding the probe row 200 locked at the verification position by the limiting assembly 400, specifically, when the probe row 200 reaches the verification position, the limiting assembly 400 enters a locked state, and the first limiting structure 410 (and the possible second limiting structure 420) moves along the second direction and cooperates with the limiting holes on the probe row 200 to limit any movement of the probe row 200 along the first direction. At this time, the probe row 200 is firmly fixed and ready for detection.

[0098] Regarding the second driving component driving the calibration device to move along the first direction so that the probe 210 is inserted into the device to be tested, specifically, when the limit component 400 has been locked, the second driving component starts and drives the entire calibration device (including the base 100 and the probe row 200) to move along the first direction until the probe 210 is accurately inserted into the device to be tested, thereby completing the detection preparation.

[0099] The first driving assembly 300, the limiting assembly 400 and the second driving assembly work closely together to ensure that each action is accurately performed in a predetermined order.

[0100] The control system is responsible for sending instructions and monitoring the status of each component to ensure the safety and reliability of the operation. The control system is the core of the entire control method. It receives external operation commands or sensor feedback information, and after processing, it issues specific action instructions to each drive component. The control system can also record the data of each operation for subsequent analysis and optimization.

[0101] The key to the entire control method lies in the connection between the three steps. First, the first drive component 300 accurately positions the probe row 200 to the calibration position; then, the limit component 400 quickly switches to a locked state to ensure that the probe row 200 does not move unnecessarily; finally, the second drive component drives the entire calibration device to move so that the probe 210 is smoothly inserted into the device to be calibrated. This step-by-step control method not only improves the stability and accuracy of the detection process, but also simplifies the operating procedures and reduces dependence on manual operation. By precisely controlling the timing and strength of each step, errors can be minimized to ensure that reliable results are obtained for each test. In addition, this method also helps protect the equipment from accidental impact or damage and extend its service life.

[0102] In some embodiments, the calibration device can be designed with two layers of probe rows 200, and the two layers of probe rows 200 correspond to two types of devices to be calibrated, for example, the probe row 200 used to calibrate the single-phase electric energy meter is located in the lower layer, and the probe row 200 suitable for calibrating the three-phase electric energy meter is located in the upper layer. When it is necessary to calibrate the single-phase electric energy meter, the probe row 200 located in the lower layer moves to the position to be calibrated, and the probe row 200 located in the upper layer retreats to the initial position, and both of them are locked by the limit assembly 400 to limit the movement of the probe row 200 used to calibrate the single-phase electric energy meter and the probe row 200 used to calibrate the single-phase electric energy meter along the first direction; when it is necessary to calibrate the three-phase electric energy meter, the probe row 200 located in the upper layer moves to the position to be calibrated, and the probe row 200 located in the lower layer retreats to the initial position, and both of them are locked by the limit assembly 400 to limit the movement of the probe row 200 used to calibrate the single-phase electric energy meter and the probe row 200 used to calibrate the single-phase electric energy meter along the first direction.

[0103] Reference Figure 7 , the control method of this application is further illustrated below: S201: Start.

[0104] S202: Determine whether the device to be tested has reached the position for testing by the testing device. If yes, execute S203; if no, execute S212.

[0105] S203: Sending a control signal to the limit assembly 400 to unlock the probe row 200 located at the initial position (the position to be tested includes the initial position and the position in the intermediate process).

[0106] S204: Sending a control signal to the first driving assembly 300 to drive the probe row 200 to move along the first direction to the testing position.

[0107] S205: Sending a control signal to the limiting assembly 400 to lock the probe row 200 at the calibration position.

[0108] S206: Sending a control signal to the first driving component 300 to stop the operation of the first driving component 300.

[0109] S207: Send a control signal to the second driving assembly to control the probe row 200 to be inserted into the device to be tested along the first direction. After detecting that the probe row 200 is inserted into the device to be tested, send a control signal to the second driving assembly to stop the operation of the second driving assembly.

[0110] S208: Determine whether the detection is completed. If yes, execute S209; if no, execute S208.

[0111] S209: Sending a control signal to the limiting assembly 400 to unlock the probe row 200 at the calibration position.

[0112] S210: Sending a control signal to the first driving assembly 300 to drive the probe row 200 to move to the initial position.

[0113] S211: Sending a control signal to the limiting assembly 400 to lock the probe row 200 at the initial position.

[0114] S212: Sending a control signal to the first driving component 300 to stop the first driving component 300 from working.

[0115] By using this control method, a first drive assembly 300 with a lower power, i.e. a smaller volume, can be set, thereby saving space inside the test device. The addition of the position limiting assembly 400 can save energy consumption of the device, i.e. the first drive assembly 300 does not need to overcome the resistance when inserting the device to be tested, and the first drive assembly 300 does not need to work all the time to maintain the state where the probe row 200 is located at the test position.

[0116] It is understandable that in some embodiments, an adaptive adjustment mechanism is introduced so that the control system can dynamically adjust the parameters of each step according to the actual situation, such as speed, acceleration and torque, etc. This can achieve the optimal operating effect under different working conditions and improve the robustness of the system.

[0117] In some embodiments, the Internet of Things technology is used to implement remote control and monitoring functions, allowing operators to view the status of equipment and issue instructions anytime and anywhere through a network interface. This is particularly useful for large factories or distributed testing sites, and can significantly improve management efficiency.

[0118] In some embodiments, for a complex system including multiple calibration devices, a multi-task scheduling algorithm is used to reasonably arrange the working order and resource allocation of each device to avoid conflicts and congestion and improve overall work efficiency.

[0119] In some embodiments, the system should have a detailed data recording function to save relevant information of each operation, such as timestamp, position coordinates, force value, etc. These data can not only be used for post-tracing, but also serve as an important basis for improving the process.

[0120] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
