[0041] Embodiment:

[0042] Referring to Figures 1-9 , a withstand voltage detection device for an electric meter, including a substrate 1, further including a clamping mechanism for clamping and limiting the electric meter, the clamping mechanism is arranged on the upper part of the substrate 1; a driving assembly 4, the clamping mechanism is driven by the driving assembly 4 to perform a clamping action; an ejecting assembly 6, the ejecting assembly 6 is arranged on the upper part of the substrate 1, and a pin 7 for inserting the wiring terminal of the electric meter is fixedly installed on the moving part of the ejecting assembly 6; a linkage assembly 5, the linkage assembly 5 is arranged between the driving assembly 4 and the ejecting assembly 6, and the driving assembly 4 drives the ejecting assembly 6 to perform a telescopic action through the linkage assembly 5. In order to realize automatic testing work, preferably, the driving assembly 4 includes a driving gear 402, the driving gear 402 is meshed with a driving rack 401 for being fixed on the main body of the conveyor, the substrate 1 is used for being fixed on the upper part of the conveyor belt of the conveyor, and when the conveyor is started, the driving gear 402 is driven by the driving rack 401 to perform a rotating action.

[0043] The above-mentioned voltage withstand detection device for an electric meter. First, the electric meter is fixed on the upper part of the substrate 1 through a clamping mechanism. The clamping mechanism is controlled by a driving component 4. Through the meshing connection of a driving gear 402 and a driving rack 401, when the conveyor starts, the driving gear 402 is driven by the driving rack 401 to rotate, thereby driving the clamping mechanism to perform a clamping action to firmly fix the electric meter. The ejecting component 6 is installed on the upper part of the substrate 1, and a pin 7 for inserting the connection terminal of the electric meter is fixed on its moving part. When the driving component 4 drives the ejecting component 6 through a linkage component 5, the pin 7 will insert into the connection terminal of the electric meter to complete the connection of the electric meter. The linkage component 5 ensures that the rotational movement of the driving component 4 can be accurately transmitted to the ejecting component 6 to realize the telescopic movement of the pin 7, making the contact of the connection terminal of the electric meter more stable and reliable. The whole process is driven by the conveyor belt of the conveyor, and the substrate 1 moves with the conveyor belt to gradually fix, insert and perform a voltage withstand test on the electric meter, realizing automatic operation. In this way, not only the detection efficiency is improved, the error of manual operation is reduced, but also it is ensured that the electric meter can maintain a stable state during the test, improving the accuracy and reliability of the detection.

[0044] In this embodiment, in order to realize the horizontal and vertical limit of the electric meter, further, the clamping mechanism includes a first clamping component 2 and a second clamping component 3. The first clamping component 2 includes a first clamping plate 201. The first clamping plate 201 is slidably installed on the upper part of the substrate 1. A hook plate 204 for inserting into the rear chute of the electric meter is integrally formed on one side of the first clamping plate 201. There are two first clamping plates 201, and the two first clamping plates 201 are symmetrically arranged. In order to realize the clamping action of the two clamping plates, furthermore, a first lead screw 203 is rotatably installed on the upper part of the substrate 1. Two opposite threads are provided on the outside of the first lead screw 203, and the two first clamping plates 201 are respectively screwed on the outside of the first lead screw 203. A guide rod 202 is fixedly connected to the upper part of the substrate 1, and the outside of the guide rod 202 is slidably connected to the first clamping plate 201.

[0045] In order to achieve stable limit of the electricity meter in the horizontal and vertical directions, two independent clamping components are designed, namely the first clamping component 2 and the second clamping component 3. First of all, the first clamping component 2 realizes the 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 substrate 1 and can move to an 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 chute of the electricity meter to provide preliminary fixation. Since the sizes of the electricity meters may vary, the first clamping component 2 includes two symmetrically arranged first clamping plates 201, which can adapt to electricity meters of different sizes. In order to achieve the synchronous clamping action of the two first clamping plates 201, a first lead screw 203 is installed on the upper part of the substrate 1. Two opposite threads are provided on the outside of the first lead screw 203, and these two threads are respectively screwed to the two first clamping plates 201. By rotating the first lead screw 203, the two first clamping plates 201 will move towards the electricity meter at the same time to complete the horizontal clamping of the electricity meter. A guide rod 202 is also fixedly connected to the upper part of the substrate 1. The function of the guide rod 202 is to ensure that the first clamping plate 201 remains stable and in the correct direction during the movement, preventing deviation or inclination during the clamping process. Through this design, the first clamping component 2 can not only firmly fix the electricity meter, but also adapt to electricity meters of different sizes, ensuring the reliability and stability of the clamping.

[0046] In this embodiment, in order to achieve the clamping action in the other direction, further, the second clamping component 3 includes second clamping plates 301. There are two second clamping plates 301, and the two second clamping plates 301 are slidably installed on both sides of the substrate 1. A contact plate 302 is detachably installed on the inner side of the second clamping plate 301 through a screw. In order to synchronously drive the second clamping component 3 to clamp when the first clamping component 2 acts, further, a first limit gear 304 is fixedly connected to the middle of the first lead screw 203. The first limit gear 304 is meshed and connected with a second limit gear 305. The second limit gear 305 is rotatably installed inside the substrate 1. A first bevel gear 306 is fixedly connected to one side of the second limit gear 305. The first bevel gear 306 is combined and connected with a second bevel gear 307. A second lead screw 303 is fixedly connected inside the second bevel gear 307. The second lead screw 303 is rotatably installed inside the substrate 1. The two oppositely arranged threaded parts of the second lead screw 303 are respectively screwed to a second clamping plate 301.

[0047] To achieve the clamping action of the electricity meter in the other direction, a second clamping component 3 is introduced in this embodiment. The second clamping component 3 is composed of two second clamping plates 301, and the two second clamping plates 301 are respectively slidably installed on both sides of the substrate 1 to ensure that the electricity meter can also be stably fixed longitudinally. A contact plate 302 is detachably installed on the inner side of each second clamping plate 301 through a screw. This design enables the contact plate 302 to be replaced or adjusted as needed to adapt to the outer shape or connection method of different electricity meters. The clamping action of the second clamping component 3 is synchronized with that of the first clamping component 2, which is achieved through a series of linkage mechanisms. Specifically, a first limit gear 304 is fixedly connected to the middle of the first lead screw 203, the first limit gear 304 is meshed and connected with a second limit gear 305, and the second limit gear 305 is fixed inside the substrate 1. A first bevel gear 306 is fixedly connected to one side of the second limit gear 305, the first bevel gear 306 is meshed and connected with a second bevel gear 307, and a second lead screw 303 is fixedly connected inside the second bevel gear 307. The second lead screw 303 is rotatably installed inside the substrate 1 and is respectively screwed to the opposite threaded parts of the two second clamping plates 301. When the first lead screw 203 rotates, the torque is transmitted through the meshing of the gears, causing the second lead screw 303 to rotate accordingly, thereby driving the two second clamping plates 301 to move towards the electricity meter simultaneously to complete the longitudinal clamping action. This design not only ensures the firm clamping of the electricity meter in two directions but also realizes the synchronization and accuracy of the clamping action through the linkage mechanism, improves the ability of the electricity meter to remain stable during the withstand voltage test, and reduces the test errors caused by loose clamping or incorrect clamping angle.

[0048] In order to realize the ejection action of the pin 7, further, the ejection assembly 6 includes a support seat 601, an ejection screw rod 602 is rotatably installed on the upper part of the support seat 601, and a slider 603 for connecting to the pressure measuring system through a wire is screwed on the outside of the ejection screw rod 602, and the slider 603 is slidably installed on the upper part of the support seat 601, and the slider 603 is fixedly connected to the pin 7 on the side close to the clamping assembly. 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 with the first linkage rotating wheel 502, the first linkage rotating wheel 502 is connected with the second linkage rotating wheel 504 through the first transmission belt 503, and the second linkage rotating wheel 504 is installed at one end of the ejection screw rod 602 through the 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 member is provided on the upper part of the support seat 601, and the transmission member 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 installed 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 member.

[0049] First, the ejection assembly 6 includes a support seat 601, and an ejection screw rod 602 is rotatably installed on the upper part of the support seat 601. The ejection screw rod 602 is connected to a slider 603 through a thread. The slider 603 is slidably installed on the upper part of the support seat 601, and the slider 603 is fixedly connected to the pin 7 on the side close to the clamping assembly. The rotation of the ejection screw rod 602 drives the slider 603 to slide on the support seat 601, thereby realizing the extension and retraction of the pin 7 and completing the plugging of the meter terminal. When the driving assembly 4 is started, the ejection screw rod 602 is driven to rotate synchronously through the linkage assembly 5 to realize the automatic plugging and retraction of the pin 7.

[0050] The linkage rod 501 is fixed on one side of the driving gear 402. When the driving gear 402 is driven by the driving rack 401 to rotate, the linkage rod 501 will also rotate accordingly. A first linkage runner 502 is fixed at the other end of the linkage rod 501, and is connected to the second linkage runner 504 through the first transmission belt 503. The second linkage runner 504 is installed at one end of the ejector lead screw 602 through a spring bearing 505. When the driving gear 402 rotates, torque is transmitted through the first transmission belt 503 to drive the second linkage runner 504 to rotate, and then drive the ejector lead screw 602 to rotate, realizing the movement of the slider 603 and the pin 7.

[0051] Here, the use of the spring bearing 505 is very crucial, ensuring that the slider 603 stops moving after reaching the limit position, but the driving assembly 4 can still operate normally.

[0052] To clean the pin 7, a cleaning assembly 8 is also introduced. The cleaning assembly 8 consists of a first brush wheel 801 and a second brush wheel 802, both of which are rotatably installed on the upper part of the support base 601. There is a gap between the first brush wheel 801 and the second brush wheel 802 to allow the pin 7 to pass through. There are transmission parts on the upper part of the support base 601, including two transmission runners 804 and a second transmission belt 805. One of the transmission runners 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 runner 804. The transmission gear 803 is meshed with the transmission rack 604 at the lower part of the slider 603. When the slider 603 moves, the transmission gear 803 is driven to rotate through the transmission rack 604, and then the first brush wheel 801 is driven to rotate through 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 accordingly. The pin 7 passes through the gap between the two brush wheels during movement, and the bristles on the brush wheels clean the pin 7, removing possible dirt or oxides, ensuring the cleanliness of the contact surface of the pin 7 to guarantee the connection stability and accuracy of the meter terminal.

[0053] Through this design, the ejector assembly 6 not only realizes the automatic plugging action of the pin 7, but also ensures the stable contact of the pin 7 on the terminal of the meter through the synchronous cooperation of the linkage assembly 5 and the driving assembly 4. At the same time, the introduction of the cleaning assembly 8 further improves the reliability of the system. By automatically cleaning the pin 7, it reduces the poor contact or measurement error caused by dirt or oxidation. The automated operation of the entire system not only improves the detection efficiency, but also reduces human error, ensuring the accuracy and reliability of the meter withstand voltage test.

[0054] In order to ensure that when the pin 7 undergoes a position change due to being clamped by the battery backing plate of the electricity meter, it will not be restricted by the first brush wheel 801 and the second brush wheel 802 in terms of the vertical movement position limit of the pin 7. 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 installed on the upper part of the support base 601. A sleeve 8011 is sleeved outside the triangular shaft 8013, and a cotton sleeve 8012 is sleeved outside the sleeve 8011. The sleeve 8011 is provided with a triangular groove, and three second magnetic plates 8015 are fixedly connected in the triangular groove of the sleeve 8011. Three first magnetic plates 8014 corresponding to the second magnetic plates 8015 are fixedly connected to the outside of the triangular shaft 8013. The first magnetic plates 8014 and the second magnetic plates 8015 repel each other. The pin 7 includes a fixing plate 701, a conductive sheet 702 is fixedly connected to the rear of the fixing plate 701. The fixing plate 701 is fixed on 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 fixing plate 701, and a moving part of the spring telescopic rod 703 is fixedly connected to a conductive plug board 704. The conductive plug board 704 is electrically connected to the conductive sheet 702.

[0055] To ensure that the pin 7 can adapt to position changes when clamped by the battery backing plate of the electricity meter and avoid restrictions on the vertical movement position of the pin 7 by the first brush wheel 801 and the second brush wheel 802, 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 wheel includes a triangular shaft 8013, and the triangular shaft 8013 is rotatably installed on the upper part of the support base 601. A sleeve 8011 is sleeved outside the triangular shaft 8013, and a cotton sleeve 8012 is sleeved on the sleeve 8011, and the cotton sleeve 8012 is used to clean the pin 7. The sleeve 8011 is provided with a triangular groove, and three second magnetic plates 8015 are fixedly connected inside the sleeve 8011 through the triangular groove, while 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 repulsive force between the first magnetic plates 8014 and the second magnetic plates 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 by the battery backing plate of the electricity meter, adapting to the position change of the pin 7 and ensuring the smooth progress of the cleaning process.

[0056] The fixing plate 701 is fixed on one side of the slider 603 and is electrically connected to the slider 603 through the conductive sheet 702. The conductive plug board 704 is electrically connected to the conductive sheet 702, and the moving part of the spring telescopic rod 703 is fixedly connected to the conductive plug board 704. When the pin 7 is subjected to the pressure of being clamped by the battery backing plate of the electricity meter, the conductive plug board 704 will move downward, driving the sleeve 8011 to move downward. The sleeve 8011 can automatically reset when the pin 7 resets under the action of magnetic force and the spring telescopic rod 703.

[0057] The whole process is controlled by the conveyor. After the detection is completed, the conveyor resets and drives the electricity meter back to the initial position. At this time, the clamping mechanism, the ejecting component 6, etc. will all reset to prepare for the next detection. Through this design, not only the position adaptability of the insertion pin 7 when the electricity meter is clamped is achieved, but also the cleaning function of the brush wheel for the insertion pin 7 is ensured not to be limited by the position change of the insertion pin 7, improving the flexibility and reliability of the system.

[0058] A method for detecting the withstand voltage of an electricity meter, including a device for detecting the withstand voltage of an electricity meter, and further including the following steps:

[0059] Step 1: Fix the substrate 1 on the conveyor belt of the conveyor and place the electricity meter at the central position of the clamping mechanism;

[0060] Step 2: Start the conveyor to transport the electricity meter to the position of the screw-tightening robot. At this time, the driving component 4 is affected by the conveyor and drives the clamping mechanism to clamp and fix the electricity meter;

[0061] Step 3: The driving component 4 also drives the ejecting component 6 through the linkage component 5 to control the insertion pin 7 to insert into the terminal slot of the electricity meter. When the electricity meter moves to the position of the screw-tightening robot, the screw-tightening robot tightens the screws of the electricity meter, so that the insertion pin 7 and the terminal slot of the electricity meter are in close contact and electrically connected to perform an automated test action.

[0062] In the present invention, the electricity meter is first fixed on the upper part of the substrate 1 through the clamping mechanism. The clamping mechanism is controlled by the driving component 4. Through the meshing connection of the driving gear 402 and the driving rack 401, when the conveyor starts, the driving gear 402 is driven to rotate by the driving rack 401, and then drives the clamping mechanism to perform a clamping action to firmly fix the electricity meter. The ejecting component 6 is installed on the upper part of the substrate 1, and the insertion pin 7 for inserting the wiring terminal of the electricity meter is fixed on its moving part. When the driving component 4 drives the ejecting component 6 through the linkage component 5, the insertion pin 7 will insert from the wiring terminal of the electricity meter to complete the connection of the electricity meter. The linkage component 5 ensures that the rotational movement of the driving component 4 can be accurately transmitted to the ejecting component 6 to realize the telescopic movement of the insertion pin 7, making the contact of the wiring terminal of the electricity meter more stable and reliable. The whole process is driven by the conveyor belt of the conveyor, and the substrate 1 moves with the conveyor belt to gradually perform the fixation, insertion, and withstand voltage test of the electricity meter, realizing automated operation. In this way, not only the detection efficiency is improved, the error of manual operation is reduced, but also it is ensured that the electricity meter can maintain a stable state during the test, improving the accuracy and reliability of the detection.

[0063] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
