[0002] With the advancement of technology, more and more electricity meters are equipped with display components, which can display the parameters collected by the electricity meter, allowing users to conveniently and intuitively view the sampling content of the electricity meter.

[0003] The testing fixtures and systems in the relevant technologies cannot directly test the display function of the display components of the electricity meter. The display function needs to be tested manually by visual inspection, which has the problems of easy to miss display component failures and low testing efficiency. Utility Model Content

[0004] This application aims to solve the technical problem that display component failures are easily missed and the detection efficiency is low in the prior art or related technologies.

[0005] Therefore, the first aspect of this application proposes a testing fixture for an electricity meter.

[0006] The second aspect of this application proposes a testing system for electricity meters.

[0007] In view of the above, according to the first aspect of this application, a testing fixture for an electricity meter is provided, comprising: a frame, the frame including an electricity meter position for placing an electricity meter; a shooting component, the sampling end of the shooting component being disposed opposite to the electricity meter position, the shooting component being used to shoot the display component of the electricity meter; and a clamping component disposed on the frame, the electricity meter position being located within the clamping component, the clamping component being used to position the electricity meter on the electricity meter position.

[0008] In this technical solution, the testing fixture for the electricity meter includes a camera component and a clamping component. The clamping component positions the electricity meter at the meter position, and the meter position is positioned opposite the sampling end of the camera component. Therefore, the testing fixture can automatically align the electricity meter with the sampling end of the camera component, and the camera component can automatically capture images of the electricity meter's display component. By comparing the captured electricity meter images with preset images, the display component of the electricity meter can be automatically tested without the need for manual visual inspection or manual image capture. It can also test multiple electricity meters simultaneously, simplifying manual operation steps and improving testing efficiency.

[0009] In some technical solutions, the testing fixture for the electricity meter may optionally include a lifting component, which is mounted on the frame and fixedly connected to the clamping component. The lifting component is used to drive the clamping component to move in order to adjust the distance between the clamping component and the shooting component.

[0010] In the technical solution of this application, a lifting component is also provided in the test fixture of the electricity meter. The lifting component can drive the clamping component to move, thereby causing the electricity meter held by the clamping component to move relative to the shooting component, adjusting the distance between the electricity meter and the shooting component, improving the effect of the shooting component in capturing the image of the electricity meter, and thus improving the testing efficiency and test effect of the display component of the electricity meter.

[0011] In some technical solutions, optionally, the lifting assembly includes: a lifting connecting plate, a clamping assembly disposed on the lifting connecting plate; and a lifting cylinder disposed on the frame, the driving end of the lifting cylinder being connected to the lifting connecting plate, the lifting cylinder being used to drive the lifting connecting plate to move toward the shooting assembly.

[0012] In the technical solution of this application, by setting a lifting connecting plate and a lifting cylinder in the clamping assembly, when it is necessary to drive the clamping assembly to move toward the shooting assembly, the lifting cylinder can drive the lifting connecting plate to drive the clamping assembly to move. Moreover, the lifting connecting plate can be connected to multiple clamping assemblies, so that the lifting cylinder can drive multiple energy meters toward the shooting assembly at one time, which further improves the testing efficiency and stability of the energy meters.

[0013] In some technical solutions, optionally, the frame includes: a partition with an opening; a clamping assembly including: at least two clamping plates located within the opening, with the meter position located between the at least two clamping plates; and a clamping cylinder located at the drive end of the lifting assembly, the drive end of the clamping cylinder being connected to the clamping plates; wherein the clamping cylinder is used to drive the at least two clamping plates to move within the opening, so that the electricity meter is positioned on the meter position.

[0014] In the technical solution of this application, at least two clamping plates are provided in the clamping assembly, and the meter position is set between the at least two clamping plates. The clamping cylinder can drive the at least two clamping plates to move toward the meter position, thereby clamping the electricity meter in the meter position, realizing the positioning of the electricity meter, improving the image effect of the electricity meter image captured by the subsequent imaging component, and thus improving the accuracy of testing the display component of the electricity meter.

[0015] In some technical solutions, the clamping assembly may optionally include: a meter baffle, disposed on the frame; and a position sensor, disposed on the meter baffle, the position sensor being used to output a position signal when the electricity meter is positioned between at least two clamping plates.

[0016] In the technical solution of this application, a positioning sensor is set in the clamping assembly, which can automatically detect whether the energy meter is between the two clamping baffles. This enables the clamping cylinder to be controlled in time when the energy meter is already between the two clamping baffles, so as to position the energy meter in the meter position, thereby further improving the stability and accuracy of the clamping assembly in positioning the energy meter.

[0017] In some technical solutions, optionally, the testing fixture of the electricity meter is connected to a transmission mechanism, which is used to transfer the electricity meter to the testing fixture of the electricity meter.

[0018] The testing fixture for the electricity meter also includes: a blocking component, which is installed through the partition plate, and one end of the blocking component is provided with a cylinder connected to the floating head; a blocking cylinder, the driving end of which is connected to the cylinder connected to the floating head, and the blocking cylinder is used to drive the blocking component to move in response to the positioning signal, so as to position the electricity meter between at least two clamping plates.

[0019] In this technical solution, the testing fixture for the electricity meter is connected to the conveying mechanism, and a blocking component and a blocking cylinder for driving the blocking component are set inside the testing fixture. When the electricity meter is detected flowing into the testing fixture, the blocking cylinder can be controlled to drive the blocking component to prevent the electricity meter from continuing to move, thereby positioning the electricity meter between at least two clamping baffles. This achieves automatic insertion of the electricity meter into the testing fixture without the need for manual insertion, further simplifying the manual operation steps and improving testing efficiency.

[0020] In some technical solutions, the testing fixture for the electricity meter may optionally include: a cabinet, with the camera and clamping components housed inside the cabinet; and an assembly plate housed inside the cabinet, with the camera and clamping components located on both sides of the assembly plate.

[0021] In the technical solution of this application, by setting an assembly plate in the cabinet and setting the shooting component and clamping component on both sides of the assembly plate, it is convenient for the staff to carry out subsequent maintenance and other operations on the shooting component and clamping component on both sides of the assembly plate.

[0022] In some technical solutions, the imaging component may optionally include: a mounting base disposed on one side of the mounting plate; and an imaging device disposed on the mounting base, at least a portion of which extends from one side of the mounting plate to the other, with the sampling end of the imaging device positioned opposite to the meter position.

[0023] In the technical solution of this application, the shooting device is mounted on one side of the assembly plate via a fixed base, and the shooting device is installed through the assembly plate, so that the sampling end of the shooting device extends to the other side of the assembly plate, thereby ensuring that the shooting device can stably acquire the image of the electricity meter and improve the accuracy of testing the electricity meter display component.

[0024] In some technical solutions, optionally, the number of shooting components is at least two, and the number of meter positions is the same as the number of shooting components, with at least two shooting components corresponding to at least two meter positions.

[0025] In this application's technical solution, there can be multiple imaging components, and the number of meter positions is the same as the number of imaging components. Each imaging component corresponds to one meter position, meaning each component is responsible for photographing the electricity meter placed at its corresponding position. By setting multiple imaging components and corresponding meter positions within the electricity meter testing fixture, the testing fixture can simultaneously test multiple electricity meters, further improving testing efficiency.

[0026] According to the second aspect of this application, a testing system for an electricity meter is proposed, comprising: a testing fixture for an electricity meter as described in any of the above technical solutions and a transmission mechanism, wherein the transmission mechanism is connected to the testing fixture for the electricity meter and is used to transmit the electricity meter into the testing fixture for the electricity meter, thus having all the beneficial technical effects of the testing fixture for the electricity meter as described in any of the above technical solutions, which will not be elaborated further here.

[0027] In the technical solution of this application, the testing fixture for the electricity meter is connected downstream of the conveying mechanism. Therefore, the electricity meter to be tested can be transported to the testing fixture through the conveying mechanism, eliminating the need for manual insertion of the electricity meter into the testing fixture and further simplifying the operation steps required by the staff.

Detailed Implementation

[0037] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, these embodiments and the features described herein can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0039] The following reference Figures 1 to 5 This application describes a test fixture and a test system for an electricity meter according to some embodiments.

[0040] According to one embodiment of this application, Figure 1 This illustration shows one of the flowcharts for a test fixture for an electricity meter provided in some embodiments of this application, such as... Figure 1 As shown, a testing fixture 100 for an electricity meter is proposed, comprising: a frame 110, the frame 110 including an electricity meter position 112 for placing an electricity meter 300; a camera component 120, the sampling end of the camera component 120 being disposed opposite to the electricity meter position 112, the camera component 120 being used to photograph the display component 302 of the electricity meter 300; and a clamping component 130 disposed on the frame 110, the electricity meter position 112 being located within the clamping component 130, the clamping component 130 being used to position the electricity meter 300 on the electricity meter position 112.

[0041] In this embodiment, the testing fixture 100 of the electricity meter is used to detect whether there is a fault in the display component 302 of the electricity meter 300. The testing fixture 100 of the electricity meter is provided with a camera component 120. When the display component 302 of the electricity meter 300 displays the content of the display command in response to the display control command, the camera component 120 can take a picture of the electricity meter 300 on the meter position 112 to obtain the screen image of the electricity meter 300. By comparing and analyzing the image content in the screen image, the fault of the display component 302 of the electricity meter 300 can be detected.

[0042] In this embodiment, the testing fixture 100 for the electricity meter includes a frame 110, on which a meter position 112 is provided. The meter position 112 is used to support the electricity meter 300, and the meter position 112 is positioned opposite to the sampling end of the imaging component 120, so that the sampling end of the imaging component 120 can directly acquire the electricity meter image. The electricity meter image includes the image features of the display component 302 of the electricity meter 300. By means of software recognition, it is possible to detect whether there is a fault in the display component 302 of the electricity meter 300 based on the electricity meter image. The testing fixture 100 for the electricity meter also includes a clamping assembly 130, which is mounted on the frame 110. The meter position 112 is located inside the clamping assembly 130. The clamping assembly 130 is used to clamp the electricity meter 300 to be tested, thereby positioning the electricity meter 300 on the meter position 112, so that the imaging assembly 120 can capture an image of the electricity meter 300 located on the meter position 112.

[0043] like Figure 2 As shown, the clamping assembly 130 is used to drive the energy meter 300 to move in a first direction, thereby positioning the energy meter 300 on the meter position 112. Figure 2 Arrow A in the diagram indicates the first direction.

[0044] It should be noted that when the electricity meter 300 is positioned on the meter position 112 by the clamping component 130, the display component 302 of the electricity meter 300 is oriented toward the imaging component 120, so that the imaging component 120 can capture the electricity meter image including the display component 302.

[0045] Figure 3 The diagram shows a topology of a test fixture 100 for an electricity meter provided in some embodiments of this application, such as... Figure 3As shown, a control line is installed on the meter position 112. One end of the control line is connected to the energy meter 300, and the other end is connected to a host computer. The host computer generates control commands through testing software to control the display component 302 and the imaging component 120 of the energy meter 300. That is, the host computer can transmit control commands to the energy meter 300 through the control line to control the display content displayed on the display component 302 of the energy meter 300. The host computer can also control the imaging component 120 to capture an image of the energy meter including the content displayed on the display component 302. The host computer compares and analyzes the captured energy meter image with a preset image. When the energy meter image matches the preset image, the display component 302 of the energy meter 300 is determined to be in a fault-free state; when the energy meter image does not match the preset image, the display component 302 of the energy meter 300 is determined to be faulty. The host computer can control the energy meter 300 to display different content in batches, and control the shooting component 120 to shoot different energy meter images when the energy meter 300 displays different content, and compare the energy meter images with the preset images, thereby improving the accuracy of the test for whether the energy meter 300 has a fault.

[0046] For example, the imaging component 120 is selected as a CCD (Charge-Coupled Device Camera). The test fixture 100 of the electricity meter can simultaneously test four electricity meters 300 and send three display control commands to each electricity meter 300 in sequence. Each display control command corresponds to the display component 302 of the electricity meter 300 displaying four display commands. That is, the electricity meter 300 can display four separate display contents in response to the control commands. When comparing the electricity meter image with the preset image, if it is determined that all four separate display contents are fault-free, the display component 302 of the electricity meter 300 is determined to be fault-free. Otherwise, the display component 302 of the electricity meter 300 is determined to be faulty.

[0047] Figure 4 The following is a schematic diagram illustrating the operating logic of the electricity meter 300 test provided in some embodiments of this application, such as... Figure 4 As shown, the test software in the host computer sends a content display command to the energy meter 300. The energy meter 300 then displays the content corresponding to the content display command and notifies the test software in the host computer that the display has been completed. The test software in the host computer instructs the imaging component 120 to capture an image of the energy meter and returns the image to the host computer test software. The host computer test software compares the energy meter image with the corresponding template image to determine the comparison result. The host computer test software summarizes the comparison results and outputs the test results of the display component 302 of the energy meter 300. It should be noted that the process of comparing the energy meter image with the template image can be executed by the processor within the imaging component 120 or by the host computer.

[0048] For example, the display component 302 of the electricity meter 300 includes a liquid crystal display screen and an LED (Light-Emitting Diode) indicator light. By capturing an image of the electricity meter with the LED indicator light by the imaging component 120, it is possible to simultaneously test whether the LED indicator light and the liquid crystal display screen are faulty.

[0049] In this embodiment, the testing fixture 100 for the electricity meter is equipped with a shooting component 120 and a clamping component 130. The clamping component 130 can position the electricity meter 300 on the meter position 112, and the meter position 112 is arranged opposite to the sampling end of the shooting component 120. Therefore, the testing fixture 100 can automatically align the electricity meter 300 with the sampling end of the shooting component 120, and the shooting component 120 can automatically acquire images including the display component 302 of the electricity meter 300. By comparing the acquired electricity meter images with preset images, the display component 302 of the electricity meter 300 can be automatically tested. There is no need to use manual visual inspection or manual image taking. It can also test multiple electricity meters 300 at the same time, which simplifies the manual operation steps and improves the testing efficiency.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the testing fixture 100 for the electricity meter further includes: a lifting component 140 disposed on the frame 110, the lifting component 140 being fixedly connected to the clamping component 130, the lifting component 140 being used to drive the clamping component 130 to move, so as to adjust the distance between the clamping component 130 and the shooting component 120.

[0051] In this embodiment, the testing fixture 100 for the electricity meter also includes a lifting component 140, which is used to drive the clamping component 130 to move and adjust the distance between the clamping component 130 and the shooting component 120, thereby adjusting the distance between the electricity meter 300 held by the clamping component 130 and the shooting component 120.

[0052] It should be noted that if the imaging component 120 is too far from the display component 302 of the energy meter 300, the captured image of the energy meter will lack clarity. Conversely, if the imaging component 120 is too close to the display component 302 of the energy meter 300, the captured image will contain missing content. Therefore, it is necessary to maintain a certain distance between the energy meter 300 and the imaging component 120 to ensure that the image captured by the imaging component 120 is clear and that the content displayed on the display component 302 in the energy meter image is complete.

[0053] like Figure 2As shown, the lifting assembly 140 is used to drive the clamping assembly 130 to move in the second direction, thereby moving the energy meter 300 on the clamping assembly 130 and adjusting the distance between the energy meter 300 and the shooting assembly 120. Figure 2 Arrow B in the diagram indicates the second direction. Specifically, for example, the second direction is the height direction of the testing fixture 100 of the electricity meter.

[0054] In this embodiment of the application, a lifting component 140 is also provided in the test fixture 100 of the electricity meter. The lifting component 140 can drive the clamping component 130 to move, thereby causing the electricity meter 300 held by the clamping component 130 to move relative to the shooting component 120, adjusting the distance between the electricity meter 300 and the shooting component 120, improving the effect of the shooting component 120 in capturing the electricity meter image, thereby improving the testing efficiency and test effect of the display component 302 of the electricity meter 300.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the lifting assembly 140 includes: a lifting connecting plate 141, a clamping assembly 130 disposed on the lifting connecting plate 141; and a lifting cylinder 142 disposed on the frame 110, the driving end of the lifting cylinder 142 being connected to the lifting connecting plate 141, the lifting cylinder 142 being used to drive the lifting connecting plate 141 to move toward the shooting assembly 120.

[0056] In this embodiment, the lifting cylinder 142 is the driving structure in the clamping assembly 130, and the driving end of the lifting cylinder 142 is fixedly connected to the lifting connecting plate 141. The lifting connecting plate 141 is used to connect the clamping assembly 130, so that the lifting cylinder 142 can controllably drive the lifting connecting plate 141 and the clamping assembly 130 to move in the second direction.

[0057] For example, the testing fixture 100 for the electricity meter includes multiple meter positions 112. Since one meter position 112 is provided on one clamping component 130, multiple clamping components 130 can be provided on the lifting connecting plate 141, so that the lifting cylinder 142 can drive multiple clamping components 130 at one time to move the electricity meter 300.

[0058] In this embodiment, by providing a lifting connecting plate 141 and a lifting cylinder 142 in the clamping assembly 130, when it is necessary to drive the clamping assembly 130 to move toward the shooting assembly 120, the lifting cylinder 142 can drive the lifting connecting plate 141 to drive the clamping assembly 130 to move. The lifting connecting plate 141 can be connected to multiple clamping assemblies 130, so that the lifting cylinder 142 can drive multiple energy meters 300 to move toward the shooting assembly 120 at one time, further improving the testing efficiency and stability of the energy meters 300.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the frame 110 includes: a partition 111 with an opening 113; the clamping assembly 130 includes: at least two clamping plates 131 located within the opening 113; the meter position 112 located between the at least two clamping plates 131; and a clamping cylinder 132 located at the drive end of the lifting assembly 140, the drive end of the clamping cylinder 132 being connected to the clamping plates 131; wherein the clamping cylinder 132 is used to drive at least two clamping plates 131 to move within the opening 113, so that the electricity meter 300 is positioned on the meter position 112.

[0060] In this embodiment, the frame 110 includes a partition 111, the shooting component 120 is located on one side of the partition 111, and the clamping component is disposed through the partition 111 via an opening 113. Driven by the lifting component 140, the clamping component can move toward or away from the shooting component 120 within the opening 113.

[0061] In this embodiment, the clamping assembly includes clamping plates 131 and clamping cylinders 132. There are two clamping plates 131, and at least two clamping plates 131 are arranged opposite each other, i.e., at least two clamping plates 131 are distributed on both sides of the meter position 112. The clamping cylinders 132 provide power to the at least two clamping plates 131, driving them to move along a first direction toward the meter position 112, thereby allowing the electricity meter 300 located between the at least two clamping plates 131 to move onto the meter position 112.

[0062] Specifically, the clamping cylinder 132 is used to drive at least two clamping plates 131 to move towards the meter position 112, thereby clamping the electricity meter 300 onto the meter position 112.

[0063] For example, there are two clamping plates 131, which are distributed on the left and right sides of the meter position 112 along the width direction of the test fixture 100.

[0064] In this embodiment, at least two clamping plates 131 are provided in the clamping assembly, and the meter position 112 is positioned between the at least two clamping plates 131. The clamping cylinder 132 can drive the at least two clamping plates 131 to move toward the meter position 112, thereby clamping the electricity meter 300 onto the meter position 112, realizing the positioning of the electricity meter 300, improving the image effect of the electricity meter image captured by the imaging component 120, and thus improving the accuracy of testing the display component 302 of the electricity meter 300.

[0065] like Figure 1 and Figure 2 As shown, in some embodiments, the clamping assembly 130 may optionally include: a meter baffle 133 disposed on the frame 110; and a position sensor 134 disposed on the meter baffle 133, the position sensor 134 being used to output a position signal when the electricity meter 300 is located between at least two clamping plates 131.

[0066] The clamping assembly 130 includes a meter baffle 133, which is mounted on the frame 110. A position sensor 134 is mounted on the meter baffle 133. The meter baffle 133 is located between two first meter baffles 133. The position sensor 134 can detect whether the electricity meter 300 is already positioned between the two clamping baffles.

[0067] Specifically, when the positioning sensor 134 detects that the energy meter 300 is between the two clamping baffles, it outputs a positioning signal. In response to the positioning signal, the host computer can drive the clamping cylinder 132 to operate, so that at least two clamping baffles move toward the energy meter position 112 to position the energy meter 300 on the energy meter position 112.

[0068] For example, the position sensor 134 can be a contact sensor or a non-contact sensor.

[0069] In this embodiment, a positioning sensor 134 is provided in the clamping assembly 130, which can automatically detect whether the energy meter 300 is positioned between the two clamping baffles. This enables the clamping cylinder 132 to be operated in a timely manner when the energy meter 300 is already positioned between the two clamping baffles, thereby positioning the energy meter 300 on the meter position 112 and further improving the stability and accuracy of the clamping assembly 130 in positioning the energy meter 300.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the test fixture 100 of the electricity meter is connected to a transmission mechanism, which is used to transfer the electricity meter 300 to the test fixture 100 of the electricity meter.

[0071] The testing fixture 100 for the electricity meter also includes: a blocking member 150, which passes through the partition 111, and one end of the blocking member 150 is provided with a cylinder-connected floating head 162; a blocking cylinder 160, the driving end of the blocking cylinder 160 being connected to the cylinder-connected floating head 162, and the blocking cylinder 160 being used to drive the blocking member 150 to move in response to a positioning signal, so as to position the electricity meter 300 between at least two clamping plates 131.

[0072] In this embodiment, the testing fixture 100 for the electricity meter is connected downstream of the conveying mechanism. Therefore, the electricity meter 300 to be tested can be transported to the testing fixture 100 via the conveying mechanism. The testing fixture 100 for the electricity meter is also provided with a blocking member 150 and a blocking cylinder 160. The blocking cylinder 160 is connected to the blocking member 150 via a cylinder connecting float 162. The blocking cylinder 160 is used to drive the blocking member 150 to move, and the blocking member 150 can move through the partition 111, thereby preventing the electricity meter 300 from continuing to move on the conveying mechanism and stopping the electricity meter 300 between at least two clamping baffles.

[0073] Specifically, during the online production process of the electricity meter 300, it is conveyed to the testing fixture 100 of the electricity meter via a conveyor belt. The testing fixture 100 is equipped with a sensor that can detect the flow of the electricity meter 300 into the testing fixture 100. The control cylinder 160 moves to lift the blocking member 150 upwards, preventing the electricity meter 300 from continuing to move. At this point, the electricity meter 300 is positioned between two clamping baffles. The position sensor 134 outputs a position signal, and the clamping cylinder 132 clamps and positions the electricity meter 300 on the meter position 112. Then, the lifting cylinder 142 drives the lifting connecting plate 141 to move upwards until the electricity meter 300 reaches the target position.

[0074] In this embodiment, the testing fixture 100 for the electricity meter is connected to the conveying mechanism, and a blocking member 150 and a blocking cylinder 160 for driving the blocking member 150 are provided in the testing fixture 100. When the electricity meter 300 is detected to flow into the testing fixture 100, the blocking cylinder 160 can be controlled to drive the blocking member 150 to block the electricity meter 300 from continuing to move, thereby positioning the electricity meter 300 between at least two clamping baffles. This realizes the automatic insertion of the electricity meter 300 into the testing fixture 100 without the need for manual insertion of the electricity meter 300, further simplifying the manual operation steps and improving the testing efficiency.

[0075] like Figure 1 As shown, in some embodiments, optionally, the testing fixture 100 for the electricity meter further includes: a cabinet 170, with the imaging component 120 and the clamping component 130 disposed inside the cabinet 170; and an assembly plate 171 disposed inside the cabinet 170, with the imaging component 120 and the clamping component 130 located on both sides of the assembly plate 171.

[0076] In this embodiment, the testing fixture 100 for the electricity meter includes a cabinet 170 and a frame 110, which serves as a supporting structure for the testing fixture 100. The frame 110 is located inside the cabinet 170, and the clamping assembly 130 on the frame 110 is also located inside the cabinet 170. An assembly plate 171 is also provided in the cabinet 170, dividing the interior of the cabinet 170 into an assembly area for the imaging assembly 120 and an area for the electricity meter 300 to be placed using the clamping assembly 130. The assembly area for the imaging assembly 120 and the area for the electricity meter 300 to be placed are located on opposite sides of the assembly plate 171. Therefore, the electricity meter 300 held by the clamping assembly 130 and the imaging assembly 120 are located on opposite sides of the assembly plate 171.

[0077] Specifically, the assembly plate 171 divides the interior of the cabinet 170 into two parts along the height of the cabinet 170. The upper part is the assembly area for the camera components 120, and all camera components 120 are set in the assembly area of ​​the camera components 120. The lower part is the placement area for the electricity meter 300. After the electricity meter 300 enters the cabinet 170, it moves within the placement area of ​​the electricity meter 300.

[0078] In this embodiment of the application, by setting an assembly plate 171 in the cabinet 170, and setting the shooting component 120 and the clamping component 130 on both sides of the assembly plate 171 respectively, it is convenient for the staff to perform maintenance and other operations on the shooting component 120 and the clamping component 130 on both sides of the assembly plate 171.

[0079] like Figure 1 As shown, in some embodiments, optionally, the imaging component 120 includes: a mounting base 121 disposed on one side of the mounting plate 171; and an imaging device 122 disposed on the mounting base 121, at least a portion of the imaging device 122 extending from one side of the mounting plate 171 to the other side, and the sampling end of the imaging device 122 being disposed opposite to the meter position 112.

[0080] In this embodiment, the imaging device 122 is mounted on one side of the mounting plate 171 via the fixing base 121, and the imaging device 122 is disposed through the mounting plate 171, so that the sampling end of the imaging device 122 extends to the other side of the mounting plate 171, thereby ensuring that the imaging device 122 can stably acquire the image of the electricity meter and improve the accuracy of testing the display component 302 of the electricity meter 300.

[0081] like Figure 1 As shown, in some embodiments, optionally, the number of shooting components 120 is at least two, and the number of meter positions 112 is the same as the number of shooting components 120, with at least two shooting components 120 corresponding to at least two meter positions 112.

[0082] In this embodiment, the number of imaging components 120 can be multiple, and the number of meter positions 112 is the same as the number of imaging components 120. Each imaging component 120 corresponds to one meter position 112, meaning each imaging component 120 is responsible for photographing the electricity meter 300 placed on its corresponding meter position 112. By setting multiple imaging components 120 and corresponding multiple meter positions 112 within the electricity meter testing fixture 100, the testing fixture can simultaneously test multiple electricity meters 300 at once, further improving testing efficiency.

[0083] like Figure 3 As shown, for example, the testing fixture 100 for the electricity meter is provided with four meter positions 112 for the electricity meter 300 and four imaging components 120, which respectively capture images of the electricity meter on the four meter positions 112.
