Description

Technical Field

[0001] This invention relates to the field of electricity meter manufacturing technology, and more specifically, to a testing fixture and testing method for electricity meter manufacturing. Background Technology

[0002] Electricity meters are instruments that measure various electrical parameters and play a vital role in the power system. They can accurately record and display the use of electricity, providing key data for the rational allocation of electricity, metering and billing, and monitoring of equipment operation status. In order to ensure the stability and accuracy of electricity performance during the production and processing of electricity meters, a set of professional and efficient testing equipment and testing methods are required.

[0003] According to patent document CN118938108A, a testing fixture for electricity meter manufacturing is disclosed, relating to the field of testing fixture technology. Its key technical features include: a base plate, a fixed seat fixedly connected to the surface of the base plate, two first wiring elements disposed on the fixed seat, a sliding seat slidably connected to the surface of the base plate, two second wiring elements disposed on the sliding seat, a driving component for driving the sliding seat closer to or further away from the fixed seat, and a positioning component for positioning the electricity meter. The purpose of this invention is to provide a testing fixture for electricity meter manufacturing.

[0004] After the entire production and processing of electricity meters is completed, a wiring test must be conducted to verify whether they can operate normally and stably. Currently, the common method is for workers to manually connect the electricity meters to dedicated testing equipment one by one. However, this traditional wiring and testing mode, which relies on manual operation, may have potential drawbacks and risks in practical applications. First, from an efficiency perspective, manual wiring is slow and time-consuming, especially in the context of large-scale production. This inefficient wiring method will significantly slow down the overall production pace, affecting capacity output and delivery cycle. On the other hand, if the electricity meter itself has quality problems during the testing process, such as incorrect installation of internal components, improper wiring layout, or insulation defects, then connecting it to a test power supply with higher voltage or larger current can easily cause serious safety accidents such as short circuits, overheating, leakage, or even fire.

Rotating plates 1216 are fixedly connected to the outer sides of the two sets of L-shaped plates 1215 on the left and the two sets of L-shaped plates 1215 on the right. The inner walls of L-shaped plates 1215 and the two sets of L-shaped plates 1215 on the right are fitted onto the outer walls of the two sets of columnar horizontal push rods 126 on the left and right. Protective shells 1217 are fixedly connected to the inner sides of the two sets of rotating plates 1216 on the left and two sets of rotating plates 1216 on the right. Protective shell grooves 1218 are provided in the middle of the outer sides of the two sets of protective shells 1217 on the left and right. L-shaped connecting plates 1214 are fixedly connected to the front and rear sides of the two sets of elliptical side plates 123 on the left and right. The outer sides of the two sets of L-shaped connecting plates 1214 on the rear side are fixedly connected to the top of the rear inner side of the L-shaped side plate 1121. When the two meters move to the outside of the two H-shaped side plates 121, the motor 1129 is started. The motor 1129 drives the transmission disc 11210 to rotate. The transmission disc 11210 drives the second transmission disc 11212 to rotate via the track 11211, which in turn causes the lead screw 11224 to start rotating. The rotation of the lead screw 11224 causes the transmission block 11214 to move backward along the lead screw 11224. The movement of the transmission block 11214 causes the vertical Z-shaped push-pull block 11215 to move backward. The vertical Z-shaped push-pull block 11215 then pushes the columnar push-pull rod 1219 to slide backward. The sliding of the columnar push-pull rod 1219 causes the rotating rod 1211 to rotate. The rotation of the rotating rod 1211 further drives the L-shaped expansion plate 1212 to unfold outward. As the expansion plate 1212 unfolds, the two sets of columnar lifting rods 1220 on the left and the two sets of columnar lifting rods 1220 on the right also move outward. The outward movement of the two sets of 1220 pushes the two sets of U-shaped lifting blocks 125 to move. The movement of the two sets of U-shaped lifting blocks 125 causes the columnar horizontal push rod 126 to slide. The sliding of the columnar horizontal push rod 126 causes the L-shaped plate 1215 to rotate within the concave hinge block 128. The rotation of the L-shaped plate 1215 causes the rotating plate 1216 to rotate. The rotation of the rotating plate 1216 causes the protective shell 1217 to rotate inward, thereby wrapping the meter and providing protection. In addition, the opposite sides of the two sets of rotating plates 1216 are now positioned at the top and bottom of the meter, fixing the meter in place. At the same time, the movement of the conveyor block 11214 also drives the columnar connecting block 11216 and the push-pull block 11217 to move backward. The movement of the push-pull block 11217 causes the sleeve block 11218 to slide on the hinge rod 1127. The sliding of the sleeve block 11218 causes the retractable expansion rod 11219 and the inner retractable expansion rod 11220 to rotate. The rotation of the retractable expansion rod 11219 and the inner retractable expansion rod 11220 causes the retractable expansion plate 11221 to slide on the side guide crossbar 1125. The sliding of the retractable expansion plate 11221 causes the retractable expansion vertical plate 11222 and the power male connector 11223 to move closer to the meter. Finally, the power male connector 11223 connects with the power interface of the meter to realize the circuit connection. When the power male connector 11223 contacts the power interface of the meter, the circuit is connected and the meter starts to receive power. At this time, the testing fixture can perform various performance tests on the meter, such as power measurement accuracy test and voltage stability test. During the test, the testing fixture will collect the meter's data in real time and transmit the data to the control system for analysis and processing. If the meter's performance indicators meet the requirements, the test is passed; if they do not meet the requirements, the test fails and the meter needs to be further inspected and repaired. After the test is completed, the motor 1129 reverses, driving the transmission disc 11210 to rotate in the opposite direction. This, in turn, drives the second transmission disc 11212 to rotate in the opposite direction via the track 11211. The lead screw 11224 also rotates in the opposite direction. The reverse rotation of the lead screw 11224 causes the conveyor block 11214 to move forward along the lead screw 11224, thereby driving the Z-shaped push-pull block 11215, the columnar push-pull rod 1219, the L-shaped expansion plate 1212, the expansion plate 11221, and other components to return to their initial positions. The power male connector 11223 is disconnected from the power interface of the meter, and the meter stops receiving power. Then, the tested meter is removed from the test platform by the components of the conveyor platform 2, completing one meter test process.

[0023] In addition, the present invention also relates to a testing fixture and testing method for electricity meter manufacturing, comprising the following steps: Step 1: Place the completed electricity meters on top of the electricity meter conveyor 29 and convey them to the right in groups of two. When a group of electricity meters is conveyed to the rear side of the two electromagnetic chucks 27, start the electric push-pull rod 24 to pull the longitudinal push rod push-pull block 25 backward. Step 2: The longitudinal push-pull rod 26 slides backward on the L-shaped guide side plate 23, driving the electromagnetic suction plate 27 to move backward. The electromagnetic suction plate 27 is energized to generate magnetic force to attract the meter, and the electric push-pull rod 24 continues to retract to the outside of the two H-shaped side plates 121. Step 3: Start the motor 1129, which drives the lead screw 11224 to rotate through the transmission disc 11210, the track 11211, and the second transmission disc 11212, causing the transmission block 11214 to move backward along the lead screw 11224; Step 4: The conveyor block 11214 drives the vertical Z-shaped push-pull block 11215 to push the columnar push-pull rod 1219 to slide, causing the rotating rod 1211 to rotate and drive the L-shaped expansion plate 1212 to unfold outward; Step 5: The L-shaped expansion plate 1212 unfolds, causing the columnar lifting rod 1220 to move, pushing the U-shaped lifting block 125 to make the columnar horizontal push rod 126 slide, thereby causing the L-shaped plate 1215 to rotate within the concave hinge block 128; Step 6: The L-shaped plate 1215 rotates, causing the rotating plate 1216 to drive the protective shell 1217 to rotate inward to wrap the meter. The two sets of rotating plates 1216 limit the top and bottom of the meter to achieve fixation. Step 7: The conveyor block 11214 drives the columnar connecting block 11216 and the push-pull block 11217 to move, so that the sleeve block 11218 slides on the hinge rod 1127. Through the retracting and expanding rod 11219 and the inner retracting and expanding rod 11220, the power male connector 11223 is connected to the power interface of the meter for power supply test. Step 8: After the test is completed, the motor 1129 reverses to reset all components, the power male connector 11223 is separated from the meter, and the tested meter is removed from the test platform 1 through the conveyor platform 2 assembly, thus completing the test process.

[0024] Working principle of this invention: The completed electricity meters are placed on top of the meter conveyor platform 29 and conveyed to the right. Two meters are conveyed as a group. When a group of meters is aligned with the rear of the two electromagnetic chucks 27, the electric push-pull rod 24 is activated, pulling the longitudinal push rod 25 backward. Since the longitudinal push rod 25 is fixedly connected to the longitudinal push rod 26, the longitudinal push rod 26 slides backward on the L-shaped guide plate 23, thereby moving the electromagnetic chucks 27 backward. When the electromagnetic chucks 27 approaches the meter, it is energized, generating a magnetic force that pulls the meter... The meter is firmly attached. Then, the electric push-pull rod 24 continues to retract backward, driving the longitudinal push-pull rod 26 and the electromagnetic suction plate 27 holding the meter to move backward to the outside of the two H-shaped side plates 121. At this time, the motor 1129 is started, and the motor 1129 drives the transmission disk 11210 to rotate. The transmission disk 11210 drives the second transmission disk 11212 to rotate through the track 11211, which in turn causes the lead screw 11224 to start rotating. The rotation of the lead screw 11224 causes the transmission block 11214 to move backward along the lead screw 11224. The movement of the transmission block 11214 causes the vertical Z-shaped push-pull block 11215 to move backward. The vertical Z-shaped push-pull block 11215 then pushes the columnar push-pull rod 1219 to slide backward. The sliding of the columnar push-pull rod 1219 causes the rotating rod 1211 to rotate. The rotation of the rotating rod 1211 further drives the L-shaped expansion plate 1212 to unfold outward. As the expansion plate 1212 unfolds, the two sets of columnar lifting rods 1220 on the left and right sides also move outwards. This outward movement of the columnar lifting rods 1220 pushes the two sets of U-shaped lifting blocks 125 to move. The movement of the U-shaped lifting blocks 125 causes the columnar horizontal push rod 126 to slide. The sliding of the columnar horizontal push rod 126 causes the L-shaped plate 1215 to rotate within the concave hinge block 128. The rotation of the L-shaped plate 1215 causes the rotating plate 1216 to rotate. The rotation of the rotating plate 1216 causes the protective shell 1217 to rotate inwards, thus enclosing the meter and providing protection. Additionally, the opposing sides of the two sets of rotating plates 1216 are now positioned at the top and bottom of the meter, fixing it in place. Simultaneously, the conveyor block... The movement of 11214 also causes the columnar connecting block 11216 and the push-pull block 11217 to move backward. The movement of the push-pull block 11217 causes the sleeve block 11218 to slide on the hinge rod 1127. The sliding of the sleeve block 11218 causes the retractable expansion rod 11219 and the inner retractable expansion rod 11220 to rotate. The rotation of the retractable expansion rod 11219 and the inner retractable expansion rod 11220 causes the retractable expansion plate 11221 to slide on the side guide crossbar 1125. The sliding of the retractable expansion plate 11221 causes the retractable expansion vertical plate 11222 and the power male connector 11223 to move closer to the meter. Finally, the power male connector 11223 connects with the power interface of the meter to realize the circuit connection. When the power male connector 11223 contacts the power interface of the meter, the circuit is connected and the meter starts to receive power.At this point, the testing fixture can perform various performance tests on the meter. After the tests are completed, the motor 1129 reverses, all components return to their initial positions, the power male connector 11223 disconnects from the meter's power interface, and the meter stops receiving power. Then, the tested meter is removed from the testing platform 1 via the components of the conveyor platform 2, completing one meter testing process.
