Description

Technical Field

[0001] This invention belongs to the field of electricity meter sampling and testing technology, specifically an electricity meter sampling and testing platform for electricity meter processing. Background Technology

[0002] An electricity meter, short for energy meter, is an indispensable measuring instrument in the power system. It is also known as a kilowatt-hour meter, watt-hour meter, etc. Whether for household electricity use, industrial production, or commercial operations, electricity meters record electricity consumption in real time, providing crucial data for electricity billing and power management. They are an important tool for ensuring an orderly power supply. After production, electricity meters typically undergo testing through a random sampling and inspection platform.

[0003] A patent with publication number CN217561710U discloses a meter sampling inspection platform device for meter processing, including a device body and a meter to be inspected. The device body has a base block on top, a slide rail on top of the base block, a slider on the outer wall of the slide rail, and an anti-slip block on one side of the slider. The device body also has a positioning plate on top and an adjusting plate on the inner wall, with a wiring mechanism inside the adjusting plate. This meter sampling inspection platform device facilitates inspection by pulling the right-side slide rail, sliding the meter to be inspected downwards along the positioning plate and the outer wall of the anti-slip block, bringing the meter's terminals into contact with the terminals. Then, the slide rail is released, and the slider secures the base block.

[0004] However, in the current meter testing process, at the start of testing, each meter needs to be moved to the vicinity of the testing platform and placed individually to align the meter's connector with the testing column. This process often requires repeated adjustments and consumes a lot of time. After testing begins, the meter can only be removed after the current meter has finished testing, and then the placement and alignment steps are repeated to start testing the next meter. Throughout the entire process, the mechanical repetitive operation not only significantly extends the testing cycle but also makes it difficult to ensure the continuity of testing. In large-scale meter testing scenarios, this inefficient testing method severely restricts the testing progress and cannot meet the actual usage requirements.

[0005] Therefore, the present invention provides a sampling inspection platform for electricity meter processing. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a meter sampling and testing platform for meter processing, comprising a body, a connecting box fixedly connected to the upper surface of the body, a feeding frame fixedly connected to one side of the connecting box, a fixing frame fixedly connected to the upper surface of the body, and a testing platform fixedly connected to one side of the fixing frame; a feeding assembly is provided inside the connecting box, the feeding assembly includes a connecting guide rail opened in the connecting box and the feeding frame, a connecting frame slidably connected inside the connecting guide rail, connecting guide blocks fixedly connected to both sides of the connecting frame, and a feeding component provided inside the connecting frame, the feeding component being used for the insertion of the meter and the testing platform; a first guide rail is fixedly connected to the upper surface of the body, a first guide block slidably connected to the first guide rail, and a feeding assembly is provided on the first guide block, the feeding assembly being used for the feeding operation after the meter testing is completed.

[0008] Preferably, the feeding component includes connecting grooves formed on both sides of the inner wall of the connecting frame, each connecting groove having a connecting spring fixedly connected thereto, two connecting springs being fixedly connected to the same connecting plate, the lower surface of the connecting plate having two rotating grooves, each rotating groove having two torsion springs fixedly connected thereto, the two torsion springs being fixedly connected to the same rotating plate, and a triggering element being provided below the rotating plate for releasing the meter.

[0009] Preferably, the trigger includes a stop plate rotatably disposed in a rotating groove, the cross-section of the stop plate being hook-shaped and abutting against the rotating plate, a pressure sensor being fixedly connected to the lower surface of the connecting plate, an auxiliary plate being fixedly connected to one side of the connecting frame, a pressing guide rail being fixedly connected to the top wall of the fixed frame, and a pressing plate being slidably connected inside the pressing guide rail.

[0010] Preferably, the feeding assembly includes a positioning plate fixed to the upper surface of the first guide block, with second guide rails on both sides of the positioning plate, a second slide plate slidably connected in each second guide rail, and an extrusion block elastically connected to one side of each second slide plate, and the two second slide plates running synchronously.

[0011] Preferably, the slide plate has a fixing groove inside, an electro-permanent magnet block is fixedly connected to the inner wall of the fixing groove, a fixing spring is also fixedly connected to the inner wall of the fixing groove, one end of the fixing spring is fixedly connected to the extrusion block, and a plurality of fixing strips are fixedly connected to one side of the extrusion block, the plurality of fixing strips being rubber strips.

[0012] Preferably, the feeding frame is provided with a concave guide plate, and the bottom end of the guide plate is rotatably connected to a rotating roller, which is used to assist the meter in falling.

[0013] Preferably, a storage box is fixedly connected inside the feeding frame, and connecting pipes are fixedly connected to both sides of the storage box. The two connecting pipes are rotatably connected to the rotating roller, and both connecting pipes are in communication with the rotating roller.

[0014] Preferably, when performing meter testing, the meter, first transferred to the unloading frame, slides down the frame into the loading component, where it is snapped in place. After being snapped in place, the meter slides along the connecting guide rail between the connecting box and the unloading frame until it reaches the testing platform. It is then aligned and inserted into the testing platform. Specifically, when the meter falls into the unloading frame, it presses against the connecting plate that slides within the connecting frame. The connecting plate, under the force of gravity, presses down on two connecting springs. After the connecting plate is compressed downwards to a certain position, it stops sliding, and the meter is snapped in place. When the connecting frame moves along the connecting guide rail to the top of the testing platform, a trigger is activated. The trigger causes the rotating plate to rotate again under the influence of the meter's gravity, causing the meter to slide onto the testing platform and be inserted into it for testing.

[0015] Preferably, after the connecting frame moves along the connecting guide rail to the top of the testing platform, the pressing plate on the top wall of the fixed frame will slide along the pressing guide rail. The pressing plate will apply pressure to the meter in the connecting frame, causing the entire connecting plate to slide down along the connecting groove until the pressure sensor on the lower surface of the connecting plate abuts against the auxiliary plate. After the pressure sensor receives the signal, the abutment plate under each rotating plate will rotate under electronic control, releasing the rotating plate. The rotating plate will rotate under the force of the torsion spring, so that the meter can fall from the connecting plate and onto the testing platform.

[0016] Preferably, after the meter test is completed, the first guide block on the first guide rail is activated. The sliding of the first guide block causes the positioning plate on its upper surface to slide. The second slide plate, which is slidably connected to both sides of the positioning plate, is moved to the top of the meter. Then, the second guide rail is activated, causing the second slide plate inside the two second guide rails to move down and be placed on both sides of the meter. Then, the electro-permanent magnet inside the second slide plate is activated, and the electro-permanent magnet is energized. The electro-permanent magnet will repel the squeezing block, causing the squeezing block to clamp the meter. A rubber fixing strip is also provided on the side of the squeezing block near the meter to assist the squeezing block in clamping the meter. Then, the second guide rail drives the second slide plate to move up, causing the meter to detach from the test platform. Then, the connecting frame can proceed with the insertion test of the next meter.

[0017] The beneficial effects of this invention are as follows: 1. The electricity meter sampling and testing platform for electricity meter processing described in this invention uses a connecting plate and a connecting spring to engage the electricity meter when it falls onto the unloading frame, achieving initial fixation and preventing slippage and collision damage. When moved to the top of the testing platform, the cooperation of the trigger and rotating plate, along with the coordinated action of the pressing plate, pressure sensor, and abutment, controls the release of the electricity meter, ensuring its insertion onto the testing platform. The entire process is highly automated, effectively ensuring the safety and stability of the electricity meters during transport and loading, greatly improving the accuracy and efficiency of testing and loading, reducing manual intervention, lowering the error rate, and providing a reliable guarantee for efficient and accurate electricity meter testing.

[0018] 2. The meter sampling and testing platform for meter processing described in this invention uses a first guide rail and a first guide block to drive a positioning plate to position the meter, laying the foundation for subsequent operations. A second guide rail controls the up-and-down movement of a second sliding plate, and the repulsive force generated by the energized electro-permanent magnet causes the squeezing block to clamp the meter. A rubber fixing strip further enhances the clamping effect, preventing the meter from slipping or being damaged. The entire process is highly automated, with smooth and continuous movements, enabling the meter to be quickly and safely removed from the testing platform, allowing the connecting frame to be promptly put into the testing of the next meter. This effectively improves testing efficiency and ensures the orderly progress of the testing work. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, an electricity meter processing sampling and testing platform includes a body 1. A connecting box 2 is fixedly connected to the upper surface of the body 1. A feeding frame 5 is fixedly connected to one side of the connecting box 2. A fixing frame 4 is fixedly connected to the upper surface of the body 1. A testing platform 41 is fixedly connected to one side of the fixing frame 4. A feeding assembly is provided inside the connecting box 2. The feeding assembly includes a connecting guide rail 22 opened in the connecting box 2 and the feeding frame 5. A connecting frame 21 is slidably connected inside the connecting guide rail 22. Connecting guide blocks 23 are fixedly connected to both sides of the connecting frame 21. A feeding component is provided inside the connecting frame 21. The feeding component is used for the insertion of the electricity meter and the testing platform 41. A first guide rail 3 is fixedly connected to the upper surface of the body 1. A first guide block 31 is slidably connected to the first guide rail 3. A feeding assembly is provided on the first guide block 31. The feeding assembly is used after the electricity meter is tested. The unloading operation includes connecting grooves 24 on both sides of the inner wall of the connecting frame 21. Each connecting groove 24 is fixedly connected to a connecting spring 25. Two connecting springs 25 are fixedly connected to the same connecting plate 26. Two rotating grooves 28 are opened on the lower surface of the connecting plate 26. Two torsion springs 211 are fixedly connected to each rotating groove 28. The same rotating plate 27 is fixedly connected between the two torsion springs 211. A trigger is provided below the rotating plate 27. The trigger is used to release the meter. The trigger includes a stop plate 29 rotatably set in the rotating groove 28. The cross section of the stop plate 29 is hook-shaped and abuts against the rotating plate 27. A pressure sensor 210 is fixedly connected to the lower surface of the connecting plate 26. An auxiliary plate 212 is fixedly connected to one side of the connecting frame 21. A pressing guide rail 6 is fixedly connected to the top wall of the fixed frame 4. A pressing plate 61 is slidably connected in the pressing guide rail 6.

[0023] Specifically, during the current meter testing process, at the start of testing, each meter needs to be moved to the vicinity of the testing platform 41 and placed individually to align the meter's connector with the testing column. This process often requires repeated adjustments and consumes a lot of time. After testing begins, the meter can only be removed after the current meter has finished testing, and then the placement and alignment steps are repeated to start testing the next meter. Throughout the entire process, the mechanical repetitive operation not only significantly extends the testing cycle but also makes it difficult to ensure the continuity of testing. In large-scale meter testing scenarios, this inefficient testing method severely restricts the testing progress and cannot meet the actual usage requirements. Therefore, the present invention solves the above problems by setting the above structure. First, when the meter is tested, the meter is first transferred to the unloading frame 5 and slides down the unloading frame 5 into the loading part, where it is snapped in place. After being snapped in place, the meter slides along the connecting guide rail 22 opened in the connecting box 2 and the unloading frame 5 to the testing table 41. Then, after alignment, it is inserted into the testing table 41. Specifically, when the meter falls into the unloading frame 5, it will squeeze the connecting plate 26 that is slidably set in the connecting frame 21. The connecting plate 26 is squeezed downward by gravity, pressing down on the two connecting springs 25. After the connecting plate 26 is compressed downward to a certain position, it stops sliding. At this time, the meter is snapped in the connecting frame 21. When the connecting frame 21 moves along the connecting guide rail 22 to the top of the testing table 41, it triggers the trigger. The trigger causes the rotating plate 27 to rotate again under the influence of the meter's gravity, so that the meter slides down onto the testing table 41 and can be inserted into the testing table 41 for testing. In addition, after the connecting frame 21 moves along the connecting guide rail 22 to the top of the testing table 41, the pressing plate 61 on the top wall of the fixed frame 4 will slide along the pressing guide rail 6. The pressing plate 61 will apply pressure to the meter in the connecting frame 21, causing the entire connecting plate 26 to slide down along the connecting groove 24 until the pressure sensor 210 on the lower surface of the connecting plate 26 abuts against the auxiliary plate 212. After the pressure sensor 210 receives the signal, the abutment plate 29 under each rotating plate 27 rotates under electronic control, releasing the rotating plate 27. The rotating plate 27 rotates under the force of the torsion spring 211, so that the meter can fall from the connecting plate 26 onto the testing table 41. When the meter falls onto the unloading frame 5, the connecting plate 26 and the connecting spring 25 engage, securing the meter within the connecting frame 21 and preventing it from slipping and colliding. As it moves above the testing platform 41, the trigger and rotating plate 27, along with the pressing plate 61, pressure sensor 210, and abutment plate 29, work together to release the meter, ensuring it is properly inserted into the testing platform 41. The entire process is highly automated, effectively ensuring the safety and stability of the meter during transport and loading, significantly improving the accuracy and efficiency of testing and loading, reducing manual intervention, lowering the error rate, and providing a reliable guarantee for efficient and accurate meter testing.

[0024] Example 2: Figures 1 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the feeding assembly includes a positioning plate 32 fixed to the upper surface of the first guide block 31. The positioning plate 32 has second guide rails 33 on both sides. A second slide plate 34 is slidably connected in each second guide rail 33. An extrusion block 35 is elastically connected to one side of each second slide plate 34. The two second slide plates 34 run synchronously. A fixing groove 38 is opened inside the slide plate. An electro-permanent magnet block is fixed to the inner wall of the fixing groove 38. A fixing spring 37 is also fixed to the inner wall of the fixing groove 38. One end of the fixing spring 37 is fixed to the extrusion block 35. A plurality of fixing strips 36 are rubber strips fixed to one side of the extrusion block 35.

[0025] Specifically, after the meter is tested, the first guide block 31 on the first guide rail 3 is activated. The sliding of the first guide block 31 causes the positioning plate 32 on its upper surface to slide. The second slide plate 34, which is slidably connected to both sides of the positioning plate 32, will be moved to the top of the meter. Then, the second guide rail 33 is activated, causing the second slide plate 34 inside the two second guide rails 33 to move down and be placed on both sides of the meter. Then, the electro-permanent magnet inside the second slide plate 34 is activated, and the electro-permanent magnet is energized. The electro-permanent magnet will repel the squeezing block 35, so that the squeezing block 35 clamps the meter. A rubber fixing strip 36 is also provided on the side of the squeezing block 35 near the meter to assist the squeezing block 35 in clamping the meter. Then, the second guide rail 33 drives the second slide plate 34 to move up, causing the meter to be removed from the test table 41. Then the connecting frame 21 can proceed with the insertion and testing of the next meter. The first guide rail 3 and the first guide block 31 drive the positioning plate 32 to position the meter, laying the foundation for subsequent operations. The second guide rail 33 controls the second slide plate 34 to move up and down. With the repulsive force generated by the energized electro-permanent magnet, the squeezing block 35 clamps the meter. The rubber fixing strip 36 further enhances the clamping effect, preventing the meter from slipping or being damaged. The whole process is highly automated and the actions are smooth and continuous. It can quickly and safely remove the meter from the testing table 41, allowing the connecting frame 21 to be put into the testing of the next meter in a timely manner, effectively improving the testing efficiency and ensuring the orderly progress of the testing work.

[0026] like Figure 8 As shown, in this embodiment, a concave guide plate 51 is provided inside the feeding frame 5. A rotating roller 52 is rotatably connected to the bottom end of the guide plate 51. The rotating roller 52 is used to assist the meter in falling. A storage box 53 is fixedly connected inside the feeding frame 5. Connecting pipes 54 are fixedly connected to both sides of the storage box 53. The two connecting pipes 54 are rotatably connected to the rotating roller 52, and both connecting pipes 54 are connected to the rotating roller 52.

[0027] Specifically, the concave guide plate 51 inside the feeding frame 5 has a rotating roller 52 rotatably connected to its bottom end. When the meter slides down along the guide plate 51, the rotating roller 52 plays an auxiliary role. The storage box 53 is fixed inside the feeding frame 5, and the lubricating oil stored in it is connected to the rotating roller 52 through the connecting pipes 54 on both sides, so that the lubricating oil can wet the surface of the rotating roller 52. During the process of the meter sliding down, it comes into contact with the rotating roller 52. Since there is lubricating oil on the surface of the rotating roller 52, the friction between the two is reduced, and the rotating roller 52 will rotate flexibly as the meter slides down, thereby helping the meter to fall more smoothly along the guide plate 51. By lubricating the surface of the rotating roller 52 with lubricating oil, the friction between the meter and the rotating roller 52 is greatly reduced when the meter slides down, which reduces the wear that the meter may cause due to friction, prevents the meter from getting stuck at the bottom of the guide plate 51, and ensures the appearance and performance of the meter. At the same time, the smooth falling process avoids the meter getting stuck or colliding, improves the feeding efficiency, and ensures the continuity of the entire testing process. Moreover, the rotating roller 52 rotates flexibly and can better adapt to the falling requirements of meters of different specifications, enhancing the versatility and stability of the equipment.

[0028] Working principle: First, when the meter is being tested, it is first transferred to the unloading frame 5 and slides down into the loading component, where it is snapped in place. After being snapped in place, the meter slides along the connecting guide rail 22 between the connecting box 2 and the unloading frame 5 until it reaches the testing table 41. Then, it is aligned and inserted into the testing table 41. Specifically, when the meter falls into the unloading frame 5, it presses the connecting plate 26 that is slidably set inside the connecting frame 21. The connecting plate 26 is pressed downward by gravity, pressing down on the two connecting springs 25. After the connecting plate 26 is compressed downward to a certain position, it stops sliding. At this time, the meter is snapped in the connecting frame 21. When the connecting frame 21 moves along the connecting guide rail 22 to the top of the testing table 41, it triggers the trigger. The trigger causes the rotating plate 27 to rotate again under the influence of the meter's gravity, causing the meter to slide onto the testing table 41 and be inserted into the testing table 41 for testing. In addition, after the connecting frame 21 moves along the connecting guide rail 22 to the top of the testing table 41, the pressing plate 61 on the top wall of the fixed frame 4 will slide along the pressing guide rail 6. The pressing plate 61 will apply pressure to the meter in the connecting frame 21, causing the entire connecting plate 26 to slide down along the connecting groove 24 until the pressure sensor 210 on the lower surface of the connecting plate 26 abuts against the auxiliary plate 212. After the pressure sensor 210 receives the signal, the abutment plate 29 under each rotating plate 27 rotates under electronic control, releasing the rotating plate 27. The rotating plate 27 rotates under the force of the torsion spring 211, so that the meter can fall from the connecting plate 26 onto the testing table 41. When the meter falls onto the unloading frame 5, the connecting plate 26 and the connecting spring 25 engage, securing the meter within the connecting frame 21 and preventing it from slipping and colliding. Once the meter is moved above the testing platform 41, the trigger and rotating plate 27, along with the pressing plate 61, pressure sensor 210, and abutment plate 29, work together to release the meter, ensuring it is properly inserted into the testing platform 41. The entire process is highly automated, effectively ensuring the safety and stability of the meter during transport and loading, significantly improving the accuracy and efficiency of testing and loading, reducing manual intervention, lowering the error rate, and providing a reliable guarantee for efficient and accurate meter testing. After the meter is tested, the first guide block 31 on the first guide rail 3 is activated. The sliding of the first guide block 31 causes the positioning plate 32 on its upper surface to slide. The second slide plate 34, which is slidably connected to both sides of the positioning plate 32, will be moved to the top of the meter. Then the second guide rail 33 is activated, causing the second slide plate 34 inside the two second guide rails 33 to move down and be placed on both sides of the meter. Then the electro-permanent magnet inside the second slide plate 34 is activated, and the electro-permanent magnet is energized. The electro-permanent magnet will repel the squeezing block 35, so that the squeezing block 35 clamps the meter. A rubber fixing strip 36 is also provided on the side of the squeezing block 35 near the meter to assist the squeezing block 35 in clamping the meter. Then the second guide rail 33 drives the second slide plate 34 to move up, causing the meter to be removed from the test table 41. Then the connecting frame 21 can proceed with the insertion and testing of the next meter. The first guide rail 3 and the first guide block 31 drive the positioning plate 32 to position the meter, laying the foundation for subsequent operations. The second guide rail 33 controls the second slide plate 34 to move up and down. With the repulsive force generated by the energized electro-permanent magnet, the squeezing block 35 clamps the meter. The rubber fixing strip 36 further enhances the clamping effect, preventing the meter from slipping or being damaged. The whole process is highly automated and the actions are smooth and continuous. It can quickly and safely remove the meter from the testing table 41, allowing the connecting frame 21 to be put into the testing of the next meter in a timely manner, effectively improving the testing efficiency and ensuring the orderly progress of the testing work.

The trigger causes the rotating plate (27) to rotate again under the influence of the meter's gravity, so that the meter slides down onto the test platform (41) and can be inserted into the test platform (41) to perform the test.

7. The meter sampling inspection platform for meter processing according to claim 6, characterized in that: After the connecting frame (21) moves along the connecting guide rail (22) to the top of the testing table (41), the pressing plate (61) on the top wall of the fixed frame (4) will slide along the pressing guide rail (6). The pressing plate (61) will apply pressure to the meter in the connecting frame (21), so that the entire connecting plate (26) slides down along the connecting groove (24) until the pressure sensor (210) on the lower surface of the connecting plate (26) abuts against the auxiliary plate (212). After the pressure sensor (210) receives the signal, the abutment plate (29) under each rotating plate (27) rotates under electric control, releasing the rotating plate (27). The rotating plate (27) rotates under the force of the torsion spring (211), so that the meter can fall from the connecting plate (26) onto the testing table (41).

8. The meter sampling inspection platform for meter processing according to claim 3, characterized in that: After the meter is tested, the first guide block (31) on the first guide rail (3) is activated. The sliding of the first guide block (31) causes the positioning plate (32) on its upper surface to slide. The second slide plate (34) connected to both sides of the positioning plate (32) will be moved to the top of the meter. Then the second guide rail (33) is activated, causing the second slide plate (34) inside the two second guide rails (33) to move down and be placed on both sides of the meter. Then the electro-permanent magnet block inside the second slide plate (34) is activated, and the electro-permanent magnet block is energized. The electro-permanent magnet block will repel the squeezing block (35), so that the squeezing block (35) clamps the meter. A rubber fixing strip (36) is also provided on the side of the squeezing block (35) near the meter to assist the squeezing block (35) in clamping the meter. Then the second guide rail (33) drives the second slide plate (34) to move up, causing the meter to leave the test table (41). Then the connecting frame (21) can perform the next meter insertion test.
