Description

Technical Field

[0001] This invention relates to the field of electricity meter testing equipment technology, specifically a flexible meter holder for automatic testing of electricity meters on an assembly line. Background Technology

[0002] Flexible meter holder technology in electricity meter testing production lines refers to automated testing, positioning, and fixing devices that are compatible with different models, sizes, and specifications of electricity meters, such as single-phase meters, three-phase meters, and smart meters. This technology aims to improve the flexibility of electricity meter testing production lines, reduce changeover time, increase testing efficiency, and adapt to the diverse, small-batch production needs of the smart meter industry.

[0003] Chinese patent application CN202410689692.9 discloses a meter connector compatible with both single-phase and three-phase energy meters. The aforementioned patent provides a calibration connector for single-phase and three-phase energy meters. When connecting a single-phase energy meter, the first positioner slides along the first and second fixed bases to a first position, the second positioner slides along the first and second fixed bases to a fourth position, the terminal block of the single-phase energy meter extends from the terminal block fixing assembly, and the auxiliary probe of the single-phase energy meter extends from the auxiliary probe fixing assembly. When connecting a directly connected three-phase energy meter, the first positioner slides along the first and second fixed bases to a second position, the second positioner slides along the first and second fixed bases to a sixth position, and the terminal block... The terminals of the directly connected three-phase energy meter on the fixed assembly extend out, and the auxiliary probe of the three-phase energy meter on the auxiliary probe fixed assembly extends out. When connecting the transformer-connected three-phase energy meter: the first positioner slides along the first and second fixed seats to the third position, and the second positioner slides along the first and second fixed seats to the fifth position. The terminals of the transformer-connected three-phase energy meter on the terminal fixing assembly extend out, and the auxiliary probe of the three-phase energy meter on the auxiliary probe fixed assembly extends out. The meter connector provided in this application is compatible with single-phase and three-phase energy meters and can connect single-phase energy meters, directly connected three-phase energy meters, and transformer-connected three-phase energy meters, solving the technical problem that traditional verification meter connectors cannot be compatible with different metering devices.

[0004] Chinese patent application CN202211629619.X discloses a device for calibrating an energy meter with temperature measurement function. After providing operating voltage and current to the energy meter under test through each high-voltage connection terminal, it detects the normal functioning of the energy meter based on feedback signals received from each functional module on the energy meter at each module connection terminal. Furthermore, it acquires the temperature of each high-voltage connection terminal in real time through each temperature sensor module, quickly interrupting the supply of operating voltage or current to the energy meter from high-voltage connection terminals whose temperature exceeds a preset temperature threshold. This not only allows for real-time monitoring of the current terminal temperature of the energy meter but also automatically cuts off overload to ensure safety when the current terminal temperature is too high. However, the following problems still exist in practical applications: Existing technical solutions generally only support a single phenotype. If there are multiple testing requirements, multiple calibration lines are needed, making it impossible to perform multi-phenotype calibration on the same calibration line. Partially compatible lines are not easy to switch between, have a high failure rate, are not suitable for large-scale deployment, and have limited compatibility with a limited number of phenotypes, failing to meet diverse needs.

[0005] Therefore, the present invention provides a flexible meter holder for automatic detection of electricity meters used in production lines to solve the above problems. Summary of the Invention

[0028] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 7 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0029] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] This invention relates to a flexible meter holder for automatic detection of electricity meters used in assembly lines. It includes a support 1, on which two symmetrically distributed slide rails 2 are connected. A sliding frame 3 is slidably connected to the support 1, with its lower end engaging with the slide rails 2. The support 1 can slide along the slide rails 2, thereby achieving back-and-forth movement adjustment. A low-voltage pin socket plate 4 is connected to the upper end of the sliding frame 3, and the low-voltage pin socket plate 4 is slidably connected to the sliding frame 3. A plurality of low-voltage pins 5 are fixedly connected to the low-voltage pin socket plate 4. A single-stroke cylinder 6 is connected to the sliding frame 3. The extension and retraction of the single-stroke cylinder 6 enables the low-voltage pin socket plate 4 to slide along the sliding frame 3. The single-stroke cylinder 6 and the low-voltage pin socket plate 4 are connected by a connecting frame, thereby adjusting the position of the low-voltage pins 5 and allowing the low-voltage pins 5 to be inserted into the corresponding electricity meter for low-voltage detection. The lower end of the low-voltage pin socket plate 4 has two symmetrically distributed secondary pin socket plates 7. The two secondary pin socket plates 7 are independently set and can be adjusted independently. Several low-voltage pins 5 are also connected to the secondary pin socket plates 7. The needle 5 performs low-voltage detection. The secondary needle base plate 7 is connected to the secondary cylinder 8 connected to the sliding frame 3. The secondary cylinder 8 is also a single-stroke cylinder. The sliding process of the secondary cylinder 8 realizes the sliding of the secondary needle base plate 7, thereby realizing the adjustment of the feed amount of the low-voltage pin 5 on the secondary needle base plate 7. The lower end of the sliding frame 3 is connected to two symmetrically distributed limiting rods 9. Two sets of left and right distributed sliding seats are slidably connected to the limiting rods 9. The two sliding seats slide on the limiting rods 9 respectively without affecting each other. Each sliding seat set includes six adjusting seats 10. Each of the adjusting seats 10 has a pin seat 11 that is slidably connected to it. Each pin seat 11 is connected to a high-voltage pin 12. Both the high-voltage pin 12 and the low-voltage pin 5 are connected to a circuit system. The circuit system realizes the testing function. The pin seat 11 is connected to a sliding drive structure inside the sliding frame 3. The sliding drive structure realizes the sliding adjustment of the pin seat 11. Each pin seat 11 can be slidably adjusted by the sliding drive structure, thereby ensuring that the high-voltage pin 12 can be adjusted according to the type of electricity meter during the electricity meter test.

[0031] In this embodiment, the energy meter is first placed in the detection area. Depending on the type of energy meter, the feed amount of the low-voltage pin 5 is selected, and either the upper or lower low-voltage pin 5 is moved and plugged in. The feed amount is controlled by the single-stroke cylinder 6 or the two-stage cylinder 8. Simultaneously, during high-voltage testing, the position of the pin holder 11 is adjusted using the sliding drive structure. In this embodiment, the sliding drive structure uses a conventional drive structure to slide a single pin holder 11 left and right, thereby enabling high-voltage testing of different energy meters. The pin holder 11 has three adjustment states, allowing for the detection of three different types of energy meters.

[0032] To achieve synchronous and effective adjustment of the needle holder 11 while ensuring its left and right sliding, the sliding drive structure includes an adjustment plate slidably connected to the sliding frame 3. The adjustment plate and the sliding frame 3 are slidably connected front and rear. A sliding groove 14 is provided on the adjustment plate. The structure of the sliding groove 14 is shown in the attached figure. Figure 3 Each needle holder 11 is fixedly connected to a cam 15, which cooperates with the slide groove 14. The sliding of the slide groove 14 drives the cam 15. During the back-and-forth sliding of the adjusting plate, the cam 15 is driven. Different slide grooves 14 have different sliding adjustment ranges for the cam 15 during the sliding process. Due to the structural characteristics of the slide groove 14, the cam 15 adjusts the three states of the high-voltage needle 12 during the left and right sliding process. By using the combination of slide groove 14 and cam 15, the position of the cam 15 in different positions of the slide groove 14 can control the position of the needle, realizing the left and right sliding adjustment of the needle holder 11, ensuring precise and smooth switching when detecting different meter types. The positions of the cam 15 and slide groove 14 correspond to different energy meters. See the attached diagram. Figure 4 The slide groove 14 is divided into three areas: a single-phase energy meter detection area, a three-phase direct energy meter detection area 19, and a three-phase inductive energy meter detection area 20. When the slide groove 14 and the cam 15 slide to different positions, they correspond to different areas and thus to different energy meters.

[0033] The adjusting plate is divided into two symmetrically distributed sliding groove plates 16. Each sliding groove plate 16 is connected to a telescopic cylinder 13. The telescopic cylinder 13 is a double-stroke cylinder. The telescopic cylinder 13 is fixedly connected to the sliding frame 3. By extending and retracting the telescopic cylinder 13, the position of the sliding groove plate 16 is adjusted, thereby enabling the sliding groove plate 16 to drive the cam 15. The left sliding groove plate 16 has six sliding grooves 14, and the right sliding groove plate 16 has seven sliding grooves 14. The shapes of the sliding grooves 14 are different. Through the cam 15 and the... The sliding groove 14, with its different positions, enables multi-level adjustment of the position of the needle holder 11. The cam 15, in conjunction with the sliding groove 14, allows for separate adjustment of the positions of different high-voltage pins 12, ensuring that the high-voltage pins 12 can be adaptively adjusted according to actual needs. All three needle holders 11 are connected to adjusting cylinders 22 on the sliding frame 3. The extension and retraction of the adjusting cylinders 22 adjusts the feed amount of the three sets of high-voltage pins 12, and also adjusts the feed amount of the corresponding needle holder 11.

[0034] The high-voltage pin 12 and the pin holder 11 are detachably connected, and the low-voltage pin 5, the low-voltage pin holder plate 4, and the secondary pin holder plate 7 are detachably connected. This embodiment provides a detachable connection method. The pin holder 11 is provided with a pin sleeve, and the high-voltage pin 12 is slidably connected inside the pin sleeve. The high-voltage pin 12 and the pin sleeve are connected by a spring, which effectively prevents voltage breakdown and enables mass production.

[0035] Both the bracket 1 and the sliding bracket 3 are provided with wiring holes 17, which not only prevents pipe wear and facilitates wiring, but also improves the convenience and aesthetics of the entire base.

[0036] In use, the present invention first places the energy meter in the detection area. Depending on the type of energy meter, the feed rate of the low-voltage pin 5 is selected, and either the upper or lower low-voltage pin 5 is moved for insertion. The feed rate of the low-voltage pin is controlled by the single-stroke cylinder 6 or the two-stage cylinder 8. While adjusting the low-voltage pin 5, the telescopic cylinder 13 is activated to slide the sliding groove plate 16. The sliding groove plate 16 can slide to different areas to suit different energy meters. Simultaneously, the extension and retraction of the adjusting cylinder 22 controls the movement of the three sets of pin holders 11. The feed rate is adjusted, thereby correspondingly adjusting the high-voltage pin 12. Simultaneously, due to the change in shape of the slide groove 14, the sliding trajectory and final position of the cam 15 are different, thus enabling adaptive adjustment according to different energy meters. When the cam 15 is in the single-phase meter detection area 18, it detects single-phase meters; when the cam 15 is in the three-phase direct energy meter detection area 19, it detects three-phase direct energy meters; and when the cam 15 is in the three-phase inductive energy meter detection area 20, it detects three-phase inductive energy meters.

[0037] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
