Abstract
Description
Technical Field
[0001] This utility model relates to the field of electricity meter testing technology, specifically to a hardware testing fixture for an entire electricity meter. Background Technology
[0002] An electricity meter (or simply electricity meter) is an instrument used to measure electrical energy consumption and is widely used in the field of electricity metering. With the rapid development of the power industry, the production and use of electricity meters are constantly increasing. To ensure the accuracy and reliability of electricity meters, they must undergo rigorous hardware testing before leaving the factory. Hardware testing is a crucial step in the electricity meter production process; it effectively identifies potential defects and problems that may occur during manufacturing, thereby guaranteeing the quality and performance of the electricity meters.
[0003] The existing testing process relies heavily on manual operation. Testing personnel need to repeatedly pick up and place the meters and manually connect the test interface, which is not only labor-intensive, but also makes it difficult to meet the needs of large-scale production.
[0004] Therefore, a hardware testing fixture for the entire electricity meter is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a hardware testing fixture for an electric meter to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A hardware testing fixture for an electric meter includes a frame. Two sets of electric meter conveying mechanisms are symmetrically arranged on the surface of the frame. A placement plate is arranged between the two sets of electric meter conveying mechanisms. A rotation control mechanism for driving the placement plate to rotate is arranged below the placement plate. A height adjustment component is arranged below the rotation control mechanism. A position adjustment component is arranged below the height adjustment component.
[0008] Furthermore, the meter conveying mechanism includes a first motor, which is fixedly mounted on the front of the frame. The output end of the first motor is fixedly connected to a first rotating shaft. Two transmission wheels are fixedly sleeved on the surface of the first rotating shaft. A conveyor belt is engaged on the surface of the transmission wheels. The placement plate is located between the two conveyor belts. A fixing frame is fixedly connected to the inner wall of the frame. A tensioning wheel is rotatably connected to the end of the fixing frame, and the tensioning wheel engages with the conveyor belt.
[0009] Furthermore, the rotation control mechanism includes a support plate, on the bottom surface of which a second motor is fixedly mounted. The output end of the second motor is fixedly connected to a second rotating shaft. The top end of the second rotating shaft is fixedly connected to a U-shaped bracket, and the right end of the placement plate is rotatably connected to the U-shaped bracket. An electric push rod is rotatably mounted on the surface of the U-shaped bracket, and the telescopic end of the electric push rod is rotatably connected to the bottom surface of the placement plate.
[0010] Furthermore, the height adjustment assembly includes a mounting box, on the inner wall of which a third motor is fixedly mounted. The output end of the third motor is fixedly connected to a first threaded rod. A support frame is threadedly connected to the surface of the first threaded rod, and the support frame is movably inserted into the top of the mounting box. The top end of the support frame is fixedly connected to a support plate.
[0011] Furthermore, the position adjustment assembly includes a base plate, on the surface of which a fourth motor is fixedly mounted, and the output end of the fourth motor is fixedly connected to a second threaded rod. Support bars are fixedly connected to the surface of the base plate, and support bars are fixedly connected to both the left and right sides of the bottom surface of the mounting box. The support bar on the left side is slidably connected to a sliding column, and the support bar on the right side is threadedly connected to the second threaded rod.
[0012] Furthermore, a testing platform is fixedly connected to the front of the frame, and a slide rail is fixedly connected to the back of the frame.
[0013] The beneficial effects of this utility model are as follows:
[0014] The meter to be tested is placed on the surface of the left-side meter conveying mechanism, causing it to be conveyed to the right. When the meter reaches the top of the placement plate, the meter conveying mechanism pauses. The height adjustment component controls the rotation control mechanism and the placement plate to rise, lifting the meter off the surface of the meter conveying mechanism. The rotation control mechanism then controls the placement plate to rotate forward, transporting the meter forward. The position adjustment component controls the height adjustment component, rotation control mechanism, and placement plate to move forward, bringing the meter closer to the inspector. The inspector can then use relevant equipment to perform hardware testing on the meter. After testing, the position adjustment component controls the height adjustment component to reset. If the meter passes the test, the rotation control mechanism controls the placement plate to move to the right. The side rotation allows the placement plate to reach the surface of the right-side meter conveying mechanism. The height adjustment component then controls the placement plate to descend, allowing the meters to fall onto the right-side meter conveying mechanism. Meters that pass inspection are then conveyed via the right-side conveying mechanism. If a product fails inspection, the rotation control mechanism controls the placement plate to rotate to the rear, and then tilts it backward, causing the meters to slide down. This allows the unqualified meters on the placement plate to be removed. Repeating these steps allows for continuous inspection. This invention facilitates automatic meter pickup and return, eliminating the need for personnel to repeatedly move meters during inspection, making the operation easier and more labor-saving, and thus improving overall inspection efficiency.

[0025] like Figures 1 to 4 As shown, a hardware testing fixture for an electricity meter includes a frame 1. Two sets of electricity meter conveying mechanisms 2 are symmetrically arranged on the surface of the frame 1. A placement plate 3 is positioned between the two sets of conveying mechanisms 2. A rotation control mechanism 4 for driving the placement plate 3 to rotate is located below the placement plate 3. A height adjustment component 5 is located below the rotation control mechanism 4, and a position adjustment component 6 is located below the height adjustment component 5. More specifically, the electricity meter to be tested is placed on the surface of the left-hand conveying mechanism 2, causing the meter to be conveyed to the right. When the meter reaches the top of the placement plate 3, the conveying mechanism 2 pauses. The height adjustment component 5 controls the rotation control mechanism 4 and the placement plate 3 to rise, lifting the meter so that it is detached from the surface of the conveying mechanism 2. Subsequently, the rotation control mechanism 4 controls the placement plate 3 to rotate forward, transporting the meter forward. The position adjustment component 6 controls the height adjustment component 5, the rotation control mechanism 4, and the placement plate 3 to move forward, bringing the meter closer to the testing personnel. The testing personnel can then use relevant equipment to perform hardware testing on the meter. After testing is completed... The position adjustment component 6 controls the height adjustment component 5 to reset. If the meter is qualified, the rotation control mechanism 4 controls the placement plate 3 to rotate to the right, so that the placement plate 3 reaches the surface of the right meter conveying mechanism 2. Then, the height adjustment component 5 controls the placement plate 3 to descend, so that the meter falls on the surface of the right meter conveying mechanism 2. The right meter conveying mechanism 2 conveys the qualified meters. If the product is unqualified, the rotation control mechanism 4 controls the placement plate 3 to rotate to the rear, and then the rotation control mechanism 4 controls the placement plate 3 to tilt to the rear, so that the meter slides to the rear, and the unqualified meter on the surface of the placement plate 3 can be unloaded. Repeat the above steps to perform continuous testing.
[0026] The meter conveying mechanism 2 includes a first motor 201, which is fixedly mounted on the front of the frame 1. A first rotating shaft 202 is fixedly connected to the output end of the first motor 201. Two transmission wheels 203 are fixedly sleeved on the surface of the first rotating shaft 202, and a conveyor belt 204 meshes with the surface of the transmission wheels 203. A placement plate 3 is located between the two conveyor belts 204. A fixing frame 205 is fixedly connected to the inner wall of the frame 1, and a tensioning wheel 206 is rotatably connected to the end of the fixing frame 205, meshing with the conveyor belt 204. It should be noted that the operation of the first motor 201 drives the first rotating shaft 202 to rotate, thereby causing the transmission wheels 203 to rotate. The tensioning wheel 206 supports the conveyor belt 204, allowing it to rotate under the action of the transmission wheels 203, thus enabling the conveyor belt 204 to transport the meter.
[0027] The rotation control mechanism 4 includes a support plate 401. A second motor 402 is fixedly mounted on the bottom surface of the support plate 401. A second rotating shaft 403 is fixedly connected to the output end of the second motor 402. A U-shaped bracket 404 is fixedly connected to the top end of the second rotating shaft 403. The right end of the placement plate 3 is rotatably connected to the U-shaped bracket 404. An electric push rod 405 is rotatably mounted on the surface of the U-shaped bracket 404, and the telescopic end of the electric push rod 405 is rotatably connected to the bottom surface of the placement plate 3. More specifically, by driving the second rotating shaft 403 to rotate through the second motor 402, the U-shaped bracket 404 can be rotated horizontally, thereby causing the placement plate 3 to rotate on the horizontal plane. By operating the electric push rod 405, the rotation of the placement plate 3 in the vertical plane can be controlled, thus facilitating the sliding of the electricity meter from the surface of the placement plate 3 for unloading defective electricity meter products.
[0028] The height adjustment assembly 5 includes a mounting box 501. A third motor 502 is fixedly mounted on the inner wall of the mounting box 501. A first threaded rod 503 is fixedly connected to the output end of the third motor 502. A support frame 504 is threadedly connected to the surface of the first threaded rod 503, and the support frame 504 is movably inserted into the top of the mounting box 501. The top end of the support frame 504 is fixedly connected to the support plate 401. It should be noted that by operating the third motor 502, the first threaded rod 503 is driven to rotate. Under the action of the thread, the support frame 504 can be moved, thereby controlling the vertical movement of the rotation control mechanism 4 and the placement plate 3.
[0029] The position adjustment component 6 includes a base plate 601. A fourth motor 602 is fixedly mounted on the surface of the base plate 601. A second threaded rod 605 is fixedly connected to the output end of the fourth motor 602. A support bar 604 is fixedly connected to the surface of the base plate 601. Support bars 604 are fixedly connected to both the left and right sides of the bottom surface of the mounting box 501. The left support bar 604 is slidably connected to the sliding column 603, and the right support bar 604 is threadedly connected to the second threaded rod 605. More specifically, the operation of the fourth motor 602 drives the second threaded rod 605 to rotate. Under the action of the thread, the support bar 604 will move, thereby controlling the longitudinal movement of the height adjustment component 5. This causes the rotation control mechanism 4, the placement plate 3, and the meter to move longitudinally. During the movement of the mounting box 501, the left support bar 604 will slide along the surface of the sliding column 603, thus enabling the mounting box 501 to slide stably.
[0030] A testing platform 7 is fixedly connected to the front of the frame 1, and a slide rail 8 is fixedly connected to the back of the frame 1. It should be noted that the testing platform 7 provides a workstation for the testing personnel. The testing personnel can place the testing equipment on the surface of the testing platform 7. By setting the slide rail 8, the meters sliding off the surface of the placement plate 3 can be guided, thereby unloading the meters with problems.
[0031] In summary: The meter to be tested is placed on the surface of the left-side meter conveying mechanism 2, causing it to be conveyed to the right. When the meter reaches above the placement plate 3, the meter conveying mechanism 2 pauses. The height adjustment component 5 controls the rotation control mechanism 4 and the placement plate 3 to rise, lifting the meter off the surface of the meter conveying mechanism 2. Subsequently, the rotation control mechanism 4 controls the placement plate 3 to rotate forward, transporting the meter forward. The position adjustment component 6 controls the height adjustment component 5, rotation control mechanism 4, and placement plate 3 to move forward, bringing the meter closer to the inspector. The inspector can then use relevant equipment to perform hardware testing on the meter. After testing, the position adjustment component 6 controls the height adjustment component 5 to reset. If the meter is qualified, the rotation control mechanism 4 controls the placement plate 3 to move forward. The placement plate 3 rotates to the right, so that it reaches the surface of the right-side meter conveying mechanism 2. Then, the height adjustment component 5 controls the placement plate 3 to descend, so that the meter falls onto the surface of the right-side meter conveying mechanism 2. The right-side meter conveying mechanism 2 conveys the qualified meters. If the product is unqualified, the rotation control mechanism 4 controls the placement plate 3 to rotate to the rear, and then controls the placement plate 3 to tilt to the rear, so that the meter slides to the rear, thus unloading the unqualified meter from the surface of the placement plate 3. The above steps are repeated to perform continuous testing. In use, this utility model achieves the effect of automatic picking up and putting back the meter. During the testing process, the testing personnel do not need to repeatedly move the meter, making the operation easier and less labor-intensive, thereby improving the overall testing efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
