[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention. Example

[0041] Reference Figures 1-9 A device for detecting withstand voltage of an electric meter includes a substrate 1, and also includes a clamping mechanism for clamping a limit electric meter, the clamping mechanism being arranged on the upper part of the substrate 1; a driving component 4, the clamping mechanism being driven by the driving component 4 to perform a clamping action; an ejection component 6, the ejection component 6 being arranged on the upper part of the substrate 1, the movable part of the ejection component 6 being fixedly mounted with a pin 7 for plugging into the electric meter terminal; a linkage component 5, the linkage component 5 being arranged between the driving component 4 and the ejection component 6, the driving component 4 driving the ejection component 6 to perform a telescopic action through the linkage component 5. In order to realize the automated testing work, preferably, the driving component 4 includes a driving gear 402, the driving gear 402 being meshedly connected with a driving tooth plate 401 for fixing on the conveyor body, the substrate 1 being used to be fixed on the upper part of the conveyor belt, and when the conveyor is started, the driving gear 402 is driven by the driving tooth plate 401 to perform a rotation action.

[0042] In the above-mentioned device for detecting withstand voltage of an electric meter, the electric meter is first fixed on the upper part of the base plate 1 by a clamping mechanism. The clamping mechanism is controlled by the driving component 4 and is connected by the meshing connection of the driving gear 402 and the driving tooth plate 401. When the conveyor is started, the driving gear 402 is driven to rotate by the driving tooth plate 401, thereby driving the clamping mechanism to perform a clamping action to firmly fix the electric meter. The ejection component 6 is installed on the upper part of the base plate 1, and a pin 7 for plugging into the terminal of the electric meter is fixed on its moving part. When the driving component 4 drives the ejection component 6 through the linkage component 5, the pin 7 will be removed from the terminal of the electric meter. Insert to complete the connection of the electric meter. The linkage component 5 ensures that the rotation action of the drive component 4 can be accurately transmitted to the ejection component 6, realizing the telescopic action of the pin 7, making the contact of the electric meter terminal more stable and reliable. The whole process is driven by the conveyor belt of the conveyor. The substrate 1 moves with the conveyor belt, and the fixation, plugging and voltage resistance test of the electric meter are gradually carried out, realizing automated operation. In this way, not only the efficiency of detection is improved and the error of manual operation is reduced, but also it is ensured that the electric meter can maintain a stable state during the test process, thereby improving the accuracy and reliability of detection.

[0043] In this embodiment, in order to achieve horizontal and vertical positioning of the electric meter, the clamping mechanism further includes a first clamping assembly 2 and a second clamping assembly 3. The first clamping assembly 2 includes a first clamping plate 201, which is slidably mounted on the upper portion of the base plate 1. A hook plate 204 for plugging into the rear chute of the electric meter is integrally formed on one side of the first clamping plate 201. Two first clamping plates 201 are provided, and the two first clamping plates 201 are symmetrically arranged. In order to achieve the clamping action of the two clamping plates, a first screw rod 203 is further rotatably mounted on the upper portion of the base plate 1. The outer portion of the first screw rod 203 has two opposing threads. The outer portion of the first screw rod 203 is respectively screwed to the two first clamping plates 201. A guide rod 202 is fixedly connected to the upper portion of the base plate 1, and the outer portion of the guide rod 202 is slidably connected to the first clamping plate 201.

[0044] In order to achieve stable positioning of the electricity meter in the horizontal and vertical directions, two independent clamping assemblies are designed, namely the first clamping assembly 2 and the second clamping assembly 3. First, the first clamping assembly 2 achieves horizontal fixation of the electricity meter through the sliding installation of the first clamping plate 201. The first clamping plate 201 is slidably installed on the upper part of the base plate 1 and can be moved to the appropriate position when the electricity meter is inserted. The hook plate 204 integrally formed on one side of the first clamping plate 201 can be inserted into the rear slide of the electricity meter to provide preliminary fixation. Because the size of the electricity meter may vary, the first clamping assembly 2 includes two symmetrically arranged first clamping plates 201 to accommodate electricity meters of different sizes. To achieve synchronous clamping of the two first clamping plates 201, a first screw rod 203 is installed on the upper part of the base plate 1. The first screw rod 203 has two opposing threads on the outside, which are screwed to the two first clamping plates 201 respectively. By rotating the first screw rod 203, the two first clamping plates 201 will move toward the electricity meter at the same time, completing the horizontal clamping of the electricity meter. A guide rod 202 is also fixedly attached to the upper portion of the base plate 1. This rod ensures that the first clamping plate 201 remains stable and oriented correctly during movement, preventing it from shifting or tilting during the clamping process. This design allows the first clamping assembly 2 to not only securely hold the meter but also accommodate meters of varying sizes, ensuring reliable and stable clamping.

[0045] In this embodiment, in order to achieve a clamping action in the other direction, further, the second clamping assembly 3 includes a second clamping plate 301, which is provided with two second clamping plates 301. The two second clamping plates 301 are slidably mounted on both sides of the base plate 1, and the inner sides of the second clamping plates 301 are detachably mounted with contact plates 302 via screws. In order to achieve synchronous driving of the second clamping assembly 3 for clamping when the first clamping assembly 2 is actuated, further, a first limiting gear 304 is fixedly connected to the middle portion of the first screw rod 203, the first limiting gear 304 is meshedly connected to the second limiting gear 305, the second limiting gear 305 is rotatably mounted inside the base plate 1, a first bevel gear 306 is fixedly connected to one side of the second limiting gear 305, the first bevel gear 306 is coupled to the second bevel gear 307, the second screw rod 303 is fixedly connected inside the second bevel gear 307, the second screw rod 303 is rotatably mounted inside the base plate 1, and the two oppositely arranged threaded portions of the second screw rod 303 are respectively screwed to one second clamping plate 301.

[0046] In order to achieve the clamping action of the electric meter in the other direction, a second clamping assembly 3 is introduced in this embodiment. The second clamping assembly 3 is composed of two second clamping plates 301, which are slidably mounted on both sides of the substrate 1 to ensure that the electric meter can also be stably fixed in the longitudinal direction. A contact plate 302 can be detachably mounted on the inner side of each second clamping plate 301 through a screw. This design allows the contact plate 302 to be replaced or adjusted as needed to adapt to the shape or connection method of different electric meters. The clamping action of the second clamping assembly 3 is performed synchronously with the first clamping assembly 2, which is achieved through a series of linkage mechanisms. Specifically, a first limiting gear 304 is fixedly connected to the middle part of the first screw rod 203, and the first limiting gear 304 is meshed and connected with the second limiting gear 305, and the second limiting gear 305 is fixed inside the substrate 1. A first bevel gear 306 is fixedly connected to one side of the second limiting gear 305, and the first bevel gear 306 is meshed and connected with the second bevel gear 307, and the second screw rod 303 is fixedly connected inside the second bevel gear 307. The second screw 303 is mounted by rotation within the base plate 1 and is threadedly connected to the opposing threaded portions of the two second clamping plates 301. When the first screw 203 rotates, the torque transmitted through the meshing of the gears causes the second screw 303 to rotate accordingly, thereby driving the two second clamping plates 301 to move toward the meter simultaneously, completing the longitudinal clamping action. This design not only ensures a secure clamping of the meter in both directions, but also achieves synchronization and precision in the clamping action through a linkage mechanism, improving the meter's ability to maintain stability during the withstand voltage test and reducing test errors caused by loose clamping or incorrect clamping angles.

[0047] In order to realize the ejection action of the pin 7, the ejection assembly 6 further includes a support base 601, and an ejection screw rod 602 is rotatably installed on the upper part of the support base 601. The ejection screw rod 602 is externally screwed with a slider 603 for connecting to the pressure measuring system through a wire. The slider 603 is slidably installed on the upper part of the support base 601, and the slider 603 is fixedly connected to the pin 7 on the side close to the clamping mechanism. In order to realize the synchronous rotation of the ejection screw rod 602 of the ejection assembly 6 driven by the driving assembly 4 through the linkage assembly 5, the pin 7 has been cleaned. Furthermore, the linkage assembly 5 includes a linkage rod 501, the linkage rod 501 is fixed on one side of the driving gear 402, and the end of the linkage rod 501 away from the driving gear 402 is fixedly connected to the first linkage runner 502, the first linkage runner 502 is connected to the second linkage runner 504 through the first transmission belt 503, and the second linkage runner 504 is installed at one end of the ejection screw rod 602 through a spring bearing 505. The detection device also includes a cleaning assembly 8, and the cleaning assembly 8 includes a first brush wheel 801 and a second brush wheel 802. The first brush wheel 801 and the second brush wheel 802 are rotatably installed on the upper part of the support seat 601 The second brush wheel 802 is located on the upper part of the first brush wheel 801, and a gap is provided between the first brush wheel 801 and the second brush wheel 802 through which the pin 7 can pass. A transmission part is provided on the upper part of the support seat 601, and the transmission part includes two transmission wheels 804 and a second transmission belt 805. The two transmission wheels 804 are connected by the second transmission belt 805, one of the transmission wheels 804 is fixed at one end of the first brush wheel 801, and a transmission gear 803 is fixedly connected to one side of the other transmission wheel 804. The transmission gear 803 is rotatably mounted on the upper part of the support seat 601, and a transmission tooth plate 604 is fixedly connected to the lower part of one side of the slider 603. The slider 603 is meshed with the transmission tooth plate 604, and the first brush wheel 801 and the second brush wheel 802 are connected by another transmission part.

[0048] First, ejector assembly 6 comprises a support base 601, on top of which a screw rod 602 is rotatably mounted. Slider 603 is threadedly connected to screw rod 602, which is slidably mounted on top of support base 601. Pin 7 is fixedly connected to the side of slider 603 near the clamping mechanism. The rotation of screw rod 602 causes slider 603 to slide on support base 601, thereby extending and retracting pin 7 and connecting the meter terminal. When drive assembly 4 is activated, the linkage assembly 5 drives screw rod 602 to rotate synchronously, enabling the automatic insertion and retraction of pin 7.

[0049] The linkage rod 501 is fixed to one side of the drive gear 402. When the drive gear 402 rotates due to the drive gear plate 401, the linkage rod 501 also rotates. A first linkage wheel 502 is fixed to the other end of the linkage rod 501, which is connected to the second linkage wheel 504 via a first transmission belt 503. The second linkage wheel 504 is mounted on one end of the ejector screw 602 via a spring-loaded bearing 505. When the drive gear 402 rotates, torque is transmitted through the first transmission belt 503, driving the second linkage wheel 504 to rotate, thereby driving the ejector screw 602 to rotate, thereby moving the slider 603 and the pin 7.

[0050] Here, the use of the spring bearing 505 is very critical, which ensures that the slider 603 does not move further after moving to the limit position, but the drive assembly 4 can still operate normally.

[0051] To clean the pins 7, a cleaning assembly 8 is also introduced. This assembly consists of a first brush wheel 801 and a second brush wheel 802, both rotatably mounted on the upper portion of the support base 601. A gap is provided between the first brush wheel 801 and the second brush wheel 802 to allow the pins 7 to pass through. A transmission component is provided on the upper portion of the support base 601, comprising two transmission wheels 804 and a second transmission belt 805. One transmission wheel 804 is fixed to one end of the first brush wheel 801, while the other transmission wheel 804 is fixedly connected to one side of a transmission gear 803, which meshes with the transmission tooth plate 604 at the bottom of the slider 603. When the slider 603 moves, the transmission tooth plate 604 drives the transmission gear 803 to rotate, which in turn drives the first brush wheel 801 to rotate via the second transmission belt 805. Due to the transmission connection between the first brush wheel 801 and the second brush wheel 802, when the first brush wheel 801 rotates, the second brush wheel 802 also rotates. During the movement, the pin 7 passes through the gap between the two brush wheels. The brush on the brush wheel cleans the pin 7, removes any dirt or oxides that may be present, and ensures that the contact surface of the pin 7 is clean, thereby ensuring the connection stability and accuracy of the meter terminal.

[0052] This design not only automates the insertion of pin 7, but also ensures stable contact between pin 7 and the meter's terminal block through the synchronized coordination of linkage assembly 5 and drive assembly 4. Furthermore, the introduction of cleaning assembly 8 further enhances system reliability by automatically cleaning pin 7, reducing contact defects and measurement errors caused by contamination or oxidation. The automated operation of the entire system not only improves testing efficiency but also reduces human error, ensuring the accuracy and reliability of meter withstand voltage testing.

[0053] In order to ensure that the pin 7 does not change its position due to the first brush wheel 801 and the second brush wheel 802 when the pin 7 is clamped by the battery pad of the electric meter, the first brush wheel 801 and the second brush wheel 802 have the same structure. The first brush wheel 801 includes a triangular shaft 8013, which is rotatably mounted on the upper part of the support seat 601, and a sleeve 8011 is installed on the outside of the triangular shaft 8013, and a cotton sleeve 8012 is installed on the outside of the sleeve 8011. The sleeve 8011 has a triangular groove, and the triangular groove of the sleeve 8011 is fixedly connected to three second magnetic plates 8 015, the outside of the triangular shaft 8013 is fixedly connected with three first magnetic plates 8014 corresponding to the second magnetic plates 8015, the first magnetic plates 8014 and the second magnetic plates 8015 are mutually exclusive, the pin 7 includes a fixed plate 701, the rear part of the fixed plate 701 is fixedly connected with a conductive sheet 702, the fixed plate 701 is fixed to one side of the slider 603, and is electrically connected to the slider 603 through the conductive sheet 702, a spring telescopic rod 703 is fixedly installed at the lower part of the fixed plate 701, the moving part of the spring telescopic rod 703 is fixedly connected with a conductive plug-in plate 704, and the conductive plug-in plate 704 is electrically connected to the conductive sheet 702.

[0054] In order to ensure that the pin 7 can adapt to position changes when the battery pad of the electric meter is clamped, and to avoid the first brush wheel 801 and the second brush wheel 802 from restricting the vertical movement position of the pin 7, a special brush wheel structure is designed. First, the brush wheel includes a first brush wheel 801 and a second brush wheel 802, which have the same structure. Each first brush includes a triangular shaft 8013, which is rotatably mounted on the upper part of the support base 601. The triangular shaft 8013 is covered with a sleeve 8011 on the outside, and a cotton sleeve 8012 is covered on the sleeve 8011. The cotton sleeve 8012 is used to clean the pin 7. The sleeve 8011 is provided with a triangular groove. Three second magnetic plates 8015 are fixedly connected to the inside of the sleeve 8011 through the triangular groove, and three first magnetic plates 8014 corresponding to the second magnetic plates 8015 are fixedly connected to the outside of the triangular shaft 8013. There is a magnetic repulsion between the first magnetic plate 8014 and the second magnetic plate 8015. This design enables the sleeve 8011 to float up and down with the movement of the pin 7 when the pin 7 is clamped on the battery pad of the electric meter, adapting to the position change of the pin 7 and ensuring the smooth progress of the cleaning process.

[0055] Fixed plate 701 is fixed to one side of slider 603 and electrically connected to it via conductive sheet 702. Conductive insert 704 is also electrically connected to conductive sheet 702. The movable portion of spring-loaded telescopic rod 703 is fixedly connected to conductive insert 704. When pin 7 is clamped by the meter battery backing plate, conductive insert 704 moves downward, driving sleeve 8011 downward. Sleeve 8011 automatically returns to its original position when pin 7 returns to its original position, thanks to magnetic force and the spring-loaded telescopic rod 703.

[0056] The entire process is controlled by a conveyor. After the test is completed, the conveyor resets, driving the meter back to its initial position. At this point, the clamping mechanism and ejector assembly 6 are reset, ready for the next test. This design not only ensures the positional adaptability of the pin 7 when the meter is clamped, but also ensures that the brush wheel's cleaning function is not restricted by the pin's position changes, improving the system's flexibility and reliability.

[0057] A method for detecting the withstand voltage of an electric meter includes a device for detecting the withstand voltage of an electric meter, and further includes the following steps:

[0058] Step 1: Fix the substrate 1 on the conveyor belt of the conveyor and place the electric meter at the center of the clamping mechanism;

[0059] Step 2: Start the conveyor to transport the electric meter to the screw-tightening robot position. At this time, the driving component 4 is affected by the conveyor to drive the clamping mechanism to clamp the electric meter;

[0060] Step 3: The driving component 4 also drives the ejection component 6 through the linkage component 5 to control the pin 7 to plug into the terminal slot of the meter. When the meter moves to the position of the screw-tightening robot, the screw-tightening robot tightens the meter screws, so that the pin 7 and the terminal slot of the meter are in close contact and electrically connected, and an automated test action is performed.

[0061] In the present invention, the electric meter is first fixed to the upper part of the base plate 1 by a clamping mechanism. The clamping mechanism is controlled by the driving component 4 and is connected by the meshing connection of the driving gear 402 and the driving tooth plate 401. When the conveyor is started, the driving gear 402 is driven to rotate by the driving tooth plate 401, thereby driving the clamping mechanism to perform a clamping action to firmly fix the electric meter. The ejection component 6 is installed on the upper part of the base plate 1, and a pin 7 for plugging into the terminal of the electric meter is fixed on its moving part. When the driving component 4 drives the ejection component 6 through the linkage component 5, the pin 7 will be inserted from the terminal of the electric meter, completing the process of the electric meter. The linkage component 5 ensures that the rotation of the drive component 4 can be accurately transmitted to the ejection component 6, realizing the extension and retraction of the pin 7, making the contact of the meter terminal more stable and reliable. The whole process is driven by the conveyor belt of the conveyor. The substrate 1 moves with the conveyor belt, and the meter is gradually fixed, plugged in and subjected to a withstand voltage test, realizing automated operation. In this way, not only the efficiency of detection is improved and the error of manual operation is reduced, but also it is ensured that the meter can maintain a stable state during the test, thereby improving the accuracy and reliability of detection.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
