Description

Technical Field

[0001] This invention relates to the field of power metering instrument testing technology, and in particular to a flexible wiring device and an automated wiring testing method for metering instrument testing. Background Technology

[0002] Measuring instruments (such as electricity meters and data acquisition terminals) must undergo accuracy verification before leaving the factory for sale to promptly identify substandard products. Currently, batch testing using automated testing systems for measuring instruments is a common technical approach. The core function of an automated testing system is to complete the verification and testing of measuring instruments. During testing, the measuring instrument needs to be provided with voltage and current signals to operate under reference conditions and output electrical energy pulse signals or clock signals for testing. The testing device receives the pulse signals and compares them with the standard electrical energy pulses of a standard electricity meter to calculate the error. Simultaneously, communication and control signals are provided to test the communication and control functions of the measuring instrument. Therefore, in an automated testing system, after the conveying system transports the electricity metering instrument to be tested to the testing unit, a connection / disconnection device is required to automatically crimp the corresponding terminal block to the tested object. After testing, the connection is automatically disconnected, and the meter is sent out.

[0003] However, different metering instruments, such as single-phase energy meters, three-phase direct energy meters, three-phase inductive energy meters, and data acquisition terminals, require corresponding dedicated terminals for wiring testing because their forms, specifications, and terminal block definitions and arrangements are different.

[0004] In the existing technology, the existing compatible connection and disconnection modules are set with two or more types of terminal blocks in the form of multi-layer lifting type, double-sided arrangement type, etc., to realize the connection of different meter types. Their complex structure leads to certain limitations in flexibility and site utilization efficiency, and cannot be expanded to include terminal blocks for subsequent new meter types.

[0005] Therefore, the existing wiring devices have technical problems such as complex structure, limited flexibility and site utilization efficiency, and inability to expand the connection sockets for subsequent new meter types. Summary of the Invention

[0026] The following is for reference Figure 1-9 The present invention provides a detailed description of a flexible wiring device and an automatic wiring detection method for measuring instruments, according to embodiments of the present invention.

[0027] In this embodiment, a flexible automated testing system for measuring instrument 106 is described by way of example.

[0028] The Measuring Instrument 106 Flexible Automated Testing System is a new type of automated instrument verification system, mainly used in power company metering centers and electricity meter manufacturers to automate the verification of electricity meters, data acquisition terminals, and other measuring instruments. The system integrates automatic transmission facilities and a fully automated electricity meter verification device into an intelligent verification system capable of automatic transmission, automatic verification, data processing, and full-process monitoring. The testing system consists of a scheduling and conveying unit, a feeding unit, an AC voltage testing unit, a visual and power-on inspection unit, an accuracy and multi-functional testing unit, a post-verification processing unit, and a unloading unit. A schematic diagram is shown below. Figure 7 As shown.

[0029] like Figure 8 The diagram illustrates the workflow of the testing system. The system primarily consists of a production scheduling platform that coordinates the issuance of meter calibration tasks from the marketing system. Meters to be calibrated are dispatched from the warehouse by the warehousing system, and then sequentially delivered to the corresponding meter loading modules via the calibration system's conveyor line. A robotic arm picks up the meters and places them onto the meter calibration conveyor line, automatically performing withstand voltage tests, power consumption tests, appearance and marking inspections, accuracy verification, and multi-functional tests. Based on the calibration and testing results, the meter conveyor line automatically sorts and transports the meters. Meters that fail to meet the standards at each stage are transported to the abnormal unloading and packing port for packing. Qualified meters are automatically sealed, have certificates of conformity affixed, and are automatically packed according to specifications based on relevant information. After packing, the warehousing system completes the warehousing of qualified and unqualified meters. Simultaneously, the production scheduling platform is notified to upload calibration information, sealing information, and packing information to the marketing system.

[0030] Depending on the object being tested, the flexible automated testing system for metering instruments 106 can be divided into specialized testing systems such as automated verification systems for single-phase energy meters, automated verification systems for three-phase energy meters, and automated testing systems for data acquisition terminals. It can also be a compatibility system that accommodates various different metering instruments 106. A typical design scheme diagram for an automated verification system for three-phase energy meters is shown below. Figure 9 As shown, based on different testing capacities and the working rhythm of each unit, each unit of the production line is equipped with one or more parallel operation units. Through automated logistics scheduling and control, assembly line operation and automated testing are realized.

[0031] The core function of the flexible automated testing system for measuring instrument 106 is to complete the verification and testing of measuring instrument 106. Measuring instrument 106 belongs to the category of metrological testing products. During testing, it needs to be provided with voltage and current signals to operate under rated conditions and output electrical energy pulse signals or clock signals for testing. The testing device receives the pulse signals and compares them with the standard electrical energy pulses of a standard energy meter to calculate the error. It also provides communication and control signals to test the communication and control functions of measuring instrument 106. Therefore, in the automated testing system, after the conveying system transports the electrical energy measuring instrument 106 to the testing unit, a set of connection and disconnection devices is required to automatically crimp the terminal block corresponding to the tested object to the tested object. After the test is completed, the connection is automatically disconnected, marked, and sent out.

[0032] It should be noted that different metering instruments 106, such as single-phase energy meters, three-phase direct-type energy meters, three-phase inductive energy meters, and data acquisition terminals, have different forms, specifications, and terminal block definitions and arrangements, thus requiring corresponding dedicated terminal blocks for wiring testing. Therefore, this embodiment of the invention provides a flexible wiring device for testing metering instruments 106.

[0033] The first aspect of this invention provides a flexible wiring device for measuring instrument 106, which is described below in conjunction with the appendix. Figure 1-6 A detailed explanation will be provided.

[0034] like Figure 1-6 As shown, a flexible wiring device for detecting a measuring instrument 106 includes a base assembly and a wiring assembly. The base assembly includes a mounting base 1 and a movable base 3. The movable base 3 is mounted on the mounting base 1 and can move back and forth. The upper surface of the movable base 3 is provided with a first socket 5 and a second socket 6. The wiring assembly includes a support base plate 101 and a first plug 102, a second plug 103, and a meter socket 104 fixed on the support base plate 101. The support base plate 101 is detachably mounted on the movable base 3. The first plug 102 is inserted into the first socket 5 to detect the current connection of the measuring instrument 106. The second plug 103... The connection to the second socket 6 for detecting voltage signals, pulse signals, and communication signals of the measuring instrument 106 is established. The connector 104 is adapted to the measuring instrument 106 to be tested and is provided with several current terminals and several flexible probes 105. The current terminals and the first plug 102 are connected by a current conversion harness 107, and the flexible probes 105 and the second plug 103 are connected by a voltage and low-voltage signal conversion harness 108. The flexible probes 105 are pluggable and detachable on the connector 104 to adapt to the low-voltage signal terminals corresponding to the different models of the measuring instruments 106.

[0035] In this embodiment, the mounting base 1 is a base plate for support and fixation, which is placed on the frame of the testing equipment during application; the forward and backward movement of the moving base 3 can be achieved by a structure such as a motor, a lead screw mechanism, and a cylinder; the first socket 5 is used to connect and conduct the current of the measuring instrument 106, and can provide the measuring instrument 106 with a corresponding current signal. The current signal transmitter can be connected to the first socket 5 to send the current signal. Therefore, the first socket 5 can be a current connector, whose structure is adapted to the first plug 102 and can be easily plugged and unplugged from the first plug 102. The second socket 6 is used to connect and conduct the voltage signal, pulse signal, communication signal, etc. of the measuring instrument 106. The second socket 6 can be a voltage and low-voltage signal connector, whose structure is adapted to the second plug 103 and can be easily plugged and unplugged from the second plug 103.

[0036] Optionally, the first socket 5 is a current connector socket for detecting the connection of the current of the measuring instrument 106, the second socket 6 is a voltage and low-voltage signal connector socket for detecting the connection of the voltage signal, pulse signal and communication signal of the measuring instrument 106, the first plug 102 is a current connector plug adapted to the first socket 5, and the second plug 103 is a voltage and low-voltage signal connector plug adapted to the second socket 6.

[0037] Preferably, the meter connector 104 is a meter connector 104 module adapted to a directly connected three-phase energy meter type, a meter connector 104 module adapted to a transformer-connected three-phase energy meter type, a meter connector 104 module for a data acquisition terminal, concentrator, or intelligent fusion terminal, or a meter connector 104 module for a single-phase energy meter, and is compatible with relevant standards and specifications. For example... Figure 2-5 As shown, the diagrams respectively illustrate the wiring components of the meter base 104 module for direct-connection three-phase energy meters, the meter base 104 module for transformer-connected three-phase energy meters, the meter base 104 module for data acquisition terminals, concentrators, and smart fusion terminals, and the meter base 104 module for single-phase energy meters. This allows for better adaptation to different meter types, and the corresponding wiring components of the meter base 104 can be selected according to the specific meter type of the metering instrument 106 to be tested.

[0038] In this embodiment, the support base plate 101 and the movable base plate 3 can be connected by a quick-release structure, which facilitates the quick installation and removal of the corresponding metering instrument 106 connector 104 during wiring. For example, they can be connected by snap-fit ​​or by magnetic attraction.

[0039] In this embodiment, when the support base plate 101 is mounted on the movable base plate 3, the first plug 102 is inserted into the first socket 5, and the second plug 103 is inserted into the second socket 6. The first plug 102 and the current terminal are connected via a current conversion harness 107 for transmitting current signals. The number of current conversion harnesses 107 can be determined by the number of current terminals. The second plug 103 and the flexible probe 105 are connected via a voltage and low-voltage signal conversion harness 108 for transmitting voltage, communication, pulse, and various control signals. It should be noted that the flexible probe 105 in this embodiment is designed for quick insertion and removal. Therefore, a corresponding flexible probe 105 interface can be designed on the connector 104. The flexible probe 105 is inserted into the corresponding interface, and then the second plug 103 can be connected to the corresponding interface via the voltage and low-voltage signal conversion harness 108 to achieve connection with the flexible probe 105.

[0040] like Figure 1 As shown, the flexible wiring device further includes a current detection loop wiring board 10 and an error calculation module 9 fixed on the surface of the mounting base plate 1. The current detection loop wiring board 10 is connected to the first socket 5 via a first connecting harness 11 to provide a current signal to the first socket 5. The error calculation module 9 is connected to the second socket 6 via a second connecting harness 12 to provide a voltage signal to the second socket 6 and to acquire the communication signal and pulse signal of the measuring instrument 106 connected to the second socket 6, so as to calculate the communication error and pulse error of the measuring instrument 106. Therefore, by setting the current detection loop wiring board 10 and the error calculation module 9, it is possible to accurately provide current and voltage signals for the measurement of the measuring instrument 106, and at the same time accurately detect the relevant errors of the communication signal and pulse signal of the measuring instrument 106. It should be noted that in this embodiment, both the current detection loop wiring board 10 and the error calculation module 9 can be a circuit board or an integrated chip, and the current detection loop wiring board 10 can be installed on the testing equipment on which the flexible wiring device is installed.

[0041] like Figure 1-6 As shown, in this embodiment, two current connector sockets and two voltage and low-voltage signal connector sockets can be provided, and correspondingly, two first plugs 102 and two second plugs 103 are also provided. Furthermore, three error calculation modules 9 can be provided, with two error calculation modules 9 connected to one of the second sockets 6 via a second wiring harness, and the other error calculation module 9 connected to the other second socket 6 via a second wiring harness. This provides voltage signals to the metering instrument 106 under test and accesses communication, pulse, and other signals of the metering instrument 106 under test to calculate errors or perform communication and other functional tests. Of course, the number of first sockets 5, second sockets 6, and the corresponding first plugs 102, second plugs 103, and error calculation modules 9 can be selected according to the number of metering instruments 106 under test. For example, Figures 2 to 5 Structural design corresponding to different quantities of measuring instruments 106 to be tested.

[0042] It should be noted that in this embodiment, the current conversion harness 107, voltage and low voltage signal conversion harness 108, first connection harness 11 and second connection harness 12 can all be selected according to the corresponding electrical harness based on the function they are to achieve, and no specific limitation is made here.

[0043] Therefore, the flexible wiring device for testing measuring instruments 106 provided in this embodiment, through the structural design of the base assembly and the wiring assembly, designs the entire wiring device as two parts that can be quickly disassembled and assembled. This allows for the design of compatible connectors 104 for different models of measuring instruments 106. In actual wiring use, the corresponding measuring instrument 106 wiring testing can be achieved through the quick disassembly and assembly of the base assembly and the wiring assembly. It also allows for the rapid replacement of corresponding modules to test different measuring instruments 106. Its structure is simple, easy to install and disassemble, and offers high flexibility and operational efficiency. The connector 104 can be designed specifically for new meter types, thus providing excellent scalability. The modular structure facilitates application and promotion, supports various layout methods and meter conveying and positioning methods, and can be applied to various testing units. It has wide adaptability and high site utilization. Through the mutual movement design between the mounting base plate 1 and the movable base plate 3, the support base plate 101 is fixed to the movable base plate 3. Then, by controlling the movement of the movable base plate 3, the automatic and rapid connection and disconnection between the wiring device and the measuring instrument 106 can be realized, which improves the wiring efficiency. Through the design of the first plug 102, the second plug 103 and the corresponding first socket 5 and second socket 6, the meter socket 104 can be quickly electrically connected and communicated to the base assembly to interact with the corresponding electrical signal module, thereby realizing the detection and analysis of current, voltage, communication and pulse signals of the measuring instrument 106. Through the design of the quick-pluggable flexible probe 105, the probe can be quickly plugged and plugged to support the automatic replacement of robots or special equipment, which improves the replacement efficiency.

[0044] like Figure 1As shown, in one embodiment, the surface of the movable base plate 3 is provided with guide positioning pins 7 and locking devices 8, and the bottom of the supporting base plate 101 is provided with corresponding positioning bushings 109 and locking bushings 110. The positioning bushings 109 cooperate with the guide positioning pins 7 to support the positioning of the base plate 101, and the locking bushings 110 cooperate with the locking devices 8 to lock the supporting base plate 101 onto the movable base plate 3. Thus, through the design of the guide positioning pins 7 and locking devices 8, rapid positioning and disassembly between the wiring assembly and the base can be achieved, making automated replacement by robots or special equipment more convenient and efficient. Here, two guide positioning pins 7 and two locking devices 8 can be provided, evenly distributed on the movable base plate 3, and two corresponding positioning bushings 109 and two locking bushings 110 can be provided, to achieve better overall stability.

[0045] like Figure 1 As shown, in one embodiment, the surface of the mounting base plate 1 is provided with a linear guide rail 2 extending in the front-to-back direction, and the bottom of the movable base plate 3 is provided with a slider that engages with the linear guide rail 2. The flexible wiring device also includes a propulsion cylinder 4 fixed to the mounting base plate 1, the end of the piston rod of the propulsion cylinder 4 being fixed to the bottom of the movable base plate 3 for pushing the movable base plate 3 to move back and forth. Thus, through the structural design of the linear guide rail 2 and the propulsion cylinder 4, the front-to-back movement of the movable base plate 3 is achieved with a more compact structure, thereby reducing the overall size of the device and improving the efficiency of site utilization.

[0046] like Figure 2-5 As shown, in one embodiment, the system also includes two L-shaped robot gripper positioning handles 111. These two handles are inverted and fixed to the surface of the support base plate 101, and are symmetrical about the central axis of the support base plate 101. Positioning pin holes are provided on the opposite end faces of the two robot gripper positioning handles 111. Therefore, by providing two robot gripper positioning handles 111 on the surface of the support base plate 101, the machine or special equipment can be disassembled and assembled more quickly and efficiently, improving overall operational efficiency.

[0047] like Figure 6As shown, in one embodiment, the flexible probe 105 includes a tail 504, a fixed rod 505, a telescopic moving rod 502, a flexible part, and a probe head 503. The tail 504 is a banana plug, and the connector 104 is provided with a corresponding banana plug hole. One end of the fixed rod 505 is fixedly connected to the tail 504, and the other end extends inward to form a telescopic hole. The telescopic hole is provided with a first spring 501. One end of the telescopic moving rod 502 extends into the telescopic hole and is connected to the first spring 501. The flexible part includes a guide rod 506 and a second spring 507. One end of the guide rod 506 is fixedly connected to the telescopic moving rod 502, and the other end is fixedly connected to the probe head 503. The second spring 507 is sleeved on the guide rod 506, and one end of it is fixed to one end of the guide rod 506, and the other end is fixed to the other end of the guide rod 506. The guide rod 506 is cut in the middle to form a flexible gap 508.

[0048] In this embodiment, the flexible probe 105 is designed with a quick-pluggable and replaceable structure and omnidirectional flexible extension and retraction, and is installed on... Figure 2-5 The connector 104 of the wiring assembly is shown. The tail 504 is designed as a standard banana plug structure, which can be quickly plugged in and out for fixing and signal transmission. The longitudinal elastic extension and retraction of the probe head 503 can be achieved by the first spring 501. The omnidirectional flexible extension and retraction of the probe head 503 is achieved by designing a flexible gap 508 in the middle of the guide rod 506 and cooperating with the second spring 507, which is used to eliminate the lateral stress of the probe head 503. Specifically, the outer diameter of the guide rod 506 is smaller than the inner diameter of the second spring 507, so that the second spring 507 can move along the guide rod 506 to obtain a certain omnidirectional activity. Through the design of the flexible gap 508, under the guidance of the second spring 507, when the probe head 503 is subjected to non-axial stress, there is a certain omnidirectional swing space to avoid deformation of the probe head 503 and the telescopic moving rod 502.

[0049] It should be noted that, as Figure 6 As shown, the dimensional parameters of the flexible probe 105 are for reference only. Specific parameter selection can be made according to... Figure 2-5 The wiring requirements for the different types of probes shown are different, so that the probe head 503 can work normally when subjected to axial force, and the deformation and bending of the telescopic moving rod 502 can be avoided.

[0050] Therefore, through the specific structural design of the flexible probe 105, a weak current signal probe with omnidirectional flexible extension and retraction is realized, which can eliminate omnidirectional wiring resistance. In particular, it can flexibly adapt to abnormal lateral resistance. After the resistance is eliminated, the probe automatically recovers without being damaged, thus improving the reliability of the probe.

[0051] The second aspect of the present invention provides an automatic wiring detection method for a flexible wiring device for testing measuring instruments 106, which will be described in detail below.

[0052] An automatic wiring detection method for testing measuring instrument 106, based on the flexible wiring device for testing measuring instrument 106 according to any one of the above claims, includes: The mounting base plate 1 of the flexible wiring device is installed at the detection station of the automated detection device, and the flexible wiring device is controlled to make the moving base plate 3 in the reset state. Determine the appropriate wiring component based on the model of the measuring instrument 106 to be tested, and determine whether the wiring component on the flexible wiring device at the current testing station is compatible with the measuring instrument 106 to be tested. If compatible, the measuring instrument 106 to be tested is sent to the wiring position, the moving base plate 3 is controlled to move forward, and the current wiring terminal of the connector 104 and the flexible probe 105 are connected to the corresponding port of the measuring instrument 106 to complete the wiring. If it is not compatible, the robot will remove the current wiring component from the mobile base plate 3 and place it in the buffer station. The robot will then match the compatible wiring component from the buffer station and install it on the mobile base plate 3, so that the first plug 102 is inserted into the first socket 5 and the second plug 103 is inserted into the second socket 6. After installation, the robot will move forward to complete the wiring. The first socket 5 releases a current signal to the measuring instrument 106 to detect the connection continuity of the current of the measuring instrument 106, and the second socket 6 releases a voltage signal to the measuring instrument 106 to detect the connection continuity of the voltage signal, pulse signal and communication signal of the measuring instrument 106. After the test is completed, the control movable base plate 3 moves backward, so that the flexible wiring device is in the reset state, and the measuring instrument 106 is output to the packaging station.

[0053] Therefore, the flexible wiring device and automatic wiring detection method for testing measuring instruments 106 provided in this embodiment solve the technical problems of existing wiring devices, such as complex structure, limited flexibility and site utilization efficiency, and inability to expand to the subsequent addition of meter sockets 104 for new meter types. The beneficial effects are achieved as follows: Through the structural design of the base assembly and wiring assembly, the entire wiring device is designed as two parts that can be quickly disassembled and assembled. This allows for the design of suitable meter sockets 104 for different models of measuring instruments 106. In actual wiring use, the corresponding measuring instrument 106 wiring detection can be achieved through the quick disassembly and assembly between the base assembly and wiring assembly. It also enables the rapid replacement of corresponding modules to test different measuring instruments 106. Its structure is simple, easy to install and disassemble, and offers high flexibility and operational efficiency. Targeted meter socket 104 designs can be made according to new meter types, resulting in excellent scalability. The modular structure facilitates application and promotion, supports various layout methods and meter delivery and positioning methods, and can be applied to various testing units, offering wide adaptability and site flexibility. High utilization rate; through the mutual movement design between the mounting base plate 1 and the movable base plate 3, the support base plate 101 is fixed to the movable base plate 3, and then the movement of the movable base plate 3 is controlled to realize the automated and rapid connection and disconnection between the wiring device and the measuring instrument 106, improving wiring efficiency; through the design of the first plug 102, the second plug 103 and the corresponding first socket 5 and second socket 6, the meter base 104 can be quickly electrically connected and communicated to the base assembly to interact with the corresponding electrical signal module, thereby realizing the detection and analysis of current, voltage, communication and pulse signals of the measuring instrument 106; through the design of the quick-pluggable flexible probe 105, the probe can be quickly plugged and plugged to replace, supporting the automatic replacement of robots or special equipment, improving replacement efficiency; through the specific structural design of the flexible probe 105, a weak electrical signal probe with omnidirectional flexible extension and retraction is realized, which can eliminate omnidirectional wiring resistance, especially for lateral abnormal resistance, it can flexibly adapt, and the probe automatically recovers after the resistance is eliminated, without damage, improving the reliability of the probe.

[0054] Furthermore, the design of the guide positioning pin 7 and the locking device 8 enables rapid positioning and disassembly between the wiring assembly and the base, making automated replacement by robots or specialized equipment more convenient and efficient.

[0055] Furthermore, through the structural design of the linear guide rail 2 and the propulsion cylinder 4, the forward and backward movement of the movable base plate 3 is achieved through a more compact structure, thereby reducing the overall volume of the device and improving the site utilization efficiency.

[0056] Furthermore, by setting up the current loop connection board 10 and the error calculation module 9, it is possible to accurately provide current and voltage signals for the measurement instrument 106, and at the same time accurately detect the relevant errors of the communication signal and pulse signal of the measurement instrument 106.

[0057] Furthermore, by setting two robot gripper operation positioning handles 111 on the surface of the support base plate 101, the machine or special equipment can be disassembled and assembled more quickly and efficiently, thereby improving the overall operation efficiency.
