[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1-5 As shown, a testing device for pulse lamps and trip lamps of electricity meters includes a conveyor line 1: an adjustable-width belt conveyor line to transport the electricity meter to the testing station, where the positioning mechanism 5 achieves precise positioning through mechanical positioning blocks and photoelectric sensors.

[0030] Meter Drag Device 2: Drives the terminal pin assembly through the driving cylinder to push it into the terminal block of the electricity meter to achieve electrical connection and provide an interface for power supply and communication of the electricity meter.

[0031] The optical signal acquisition device 3 includes a pulse lamp detection head 9 and a trip lamp detection head 8. It is driven by a lifting cylinder to press down and collect optical signals at the lamp position. It uses a photoelectric sensor to detect the presence or absence of light and the flicker frequency.

[0032] Screen flip button pressing mechanism 4: The screen flip button is pressed by a cylinder to quickly turn off the trip light so as to verify the signal in the tripped state.

[0033] Defective product rejection mechanism 6: It consists of rejection cylinder and diversion baffle, which guides defective products to the waste channel according to the instructions of the host computer.

[0034] The host computer control system coordinates the actions of various components and executes the detection process: locating the energy meter → electrical connection → powering on to check the trip light → flipping the screen to turn off the light → tripping command detection → closing the circuit and checking the pulse light → result judgment and rejection.

[0035] The operation process is as follows:

[0036] 1. When the equipment is started, the conveyor line 1 transports the electricity meter to the meter position, and the positioning mechanism 5 positions the electricity meter.

[0037] 2. After all the electricity meters are in place, the meter support device 2 pushes into the electricity meter terminals, and the optical signal acquisition device 3 presses down.

[0038] 3. Apply the rated voltage to the electricity meter. After the electricity meter is powered on, the trip light will illuminate. The optical signal acquisition device 3 will collect the light signal of the trip light to verify the quality of the trip light and whether the polarity of the components is correct.

[0039] 4. Screen Flip Button Press Mechanism: Pressing the screen flip button will turn off the trip light. Pressing the screen flip button quickly turns off the trip light, saving time for the next step of verifying the trip light when the electricity meter is in the off state.

[0040] 5. The host computer sends a trip command to the energy meter, the trip light illuminates, and the optical signal acquisition device 3 collects the trip light signal to verify the consistency between the trip light signal and the energy meter command.

[0041] 6. The host computer sends a closing command to the energy meter, and the energy meter closes. Rated voltage and current are applied to the energy meter, the pulse lamp flashes, and the light signal acquisition device 3 collects the pulse lamp light signal to verify the quality of the pulse lamp and whether the polarity of the components is correct.

[0042] 7. After inspection, the products are automatically discharged, and defective products are rejected by the defective product rejection mechanism 6.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment have been appropriately combined to form other embodiments that are easy for those skilled in the art to understand.
