Description

Technical Field

[0001] This application relates to the field of verification technology, specifically to an automatic verification device for three-phase electricity meters. Background Technology

[0002] The three-phase energy meter automatic verification device is a professional equipment used for automated testing of energy meter performance. Its core function is to comprehensively evaluate the metering accuracy, functional reliability and appearance integrity of the energy meter by integrating high-precision detection modules and automatic control technology.

[0003] In the production and quality inspection process of electricity meters, appearance inspection is a key step to ensure that the product meets technical specifications.

[0004] For example, patent CN206740955U discloses an automated verification system for three-phase electricity meters. This patent specifically adopts the design principle of parallel operation and closed-loop flow for the time-consuming verification process of electricity meters and the buffering process of unqualified meters, which solves the problem of continuous and efficient operation of the three-phase electricity meter single-current automatic verification line and makes the space layout more reasonable.

[0005] In the actual process of inspecting the appearance, the natural or artificial light source in the inspection environment may change due to time, weather or human factors, which will affect the overall light intensity of the inspection area. Insufficient light source will cause the detailed information on the surface of the inspected electricity meter (such as tiny scratches, stains, etc.) to be unable to be clearly captured, thereby reducing the inspection accuracy.

[0006] Therefore, it is necessary to provide an automatic calibration device for three-phase electricity meters to solve the above problems.

Detailed Implementation

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] like Figures 1-2 As shown, this application provides an automatic calibration device for three-phase energy meters. The calibration device is installed on a three-phase energy meter testing platform and is used to perform visual inspection on three-phase energy meters. Specifically, the calibration device includes a base 1 and a placement plate 2 fixedly installed on the upper end of the base 1. The placement plate 2 is used to place the three-phase energy meter to be tested.

[0037] Furthermore, a detection mechanism 3 is provided at the upper end of the base 1, directly above the placement plate 2. The detection mechanism 3 includes columns 30 fixedly installed on both sides of the placement plate 2 at the upper end of the base 1, and a first transmission assembly 31 is provided at the upper end of the columns 30. In this application, the first transmission assembly 31 can be a screw transmission mechanism in the prior art that is applicable to this embodiment. The first transmission assembly 31 has a first slider 310, and a crossbeam 35 is fixedly installed between the first sliders 310. Thus, by activating the first transmission assembly 31, the first sliders 310 can be driven to move the crossbeam 35 horizontally.

[0038] Furthermore, a second transmission component 32 is provided on the crossbeam 35. In this application, the second transmission component 32 can be a lead screw transmission mechanism that is applicable to this embodiment in the prior art. The second transmission component 32 has a second slider 320, and a mounting plate 33 is fixedly provided on the second slider 320. Thus, starting the first transmission component 31 to drive the first slider 310 can drive the mounting plate 33 to perform translational movement along the crossbeam 35.

[0039] Meanwhile, a detection head 34 is fixedly installed on one side of the mounting plate 33. In this application, the detection head 34 can be a camera or other image acquisition device, used to perform appearance inspection on the three-phase energy meter placed on the placement plate 2. The detection head 34 can achieve two-dimensional translation in the horizontal plane through the coordinated action of the first transmission component 31 and the second transmission component 32, thereby inspecting various parts of the energy meter.

[0040] To prevent insufficient light during the testing process, such as Figures 2-4 As shown, a lighting mechanism 4 is provided at the lower end of the mounting plate 33. The lighting mechanism 4 illuminates the three-phase energy meter on the mounting plate 2 from various directions, thereby avoiding dark corners during the testing process to a certain extent.

[0041] The lighting mechanism 4 includes a positioning frame 40 fixedly installed at the lower end of the mounting plate 33. The size of the positioning frame 40 is larger than the size of the three-phase energy meter on the placement plate 2, so that the three-phase energy meter can be positioned before testing. It should be noted that the positioning frame 40 is located directly below the testing head 34, which facilitates subsequent testing.

[0042] Furthermore, cylinders 41 are fixedly installed around the positioning frame 40, and a fixed plate 42 is fixedly installed at the output end of the cylinder 41, so that starting the cylinder 41 can drive the fixed plate 42 to move vertically up and down.

[0043] Meanwhile, two sets of fixed seats 43 are fixedly installed on the fixed plate 42. A rotating shaft 45 is rotatably installed between the fixed seats 43. A motor 44 is fixedly installed on the fixed plate 42. The output end of the motor 44 passes through the fixed seat 43 and is fixedly connected to the rotating shaft 45. Thus, starting the motor 44 can drive the rotating shaft 45 to rotate between the fixed seats 43.

[0044] Furthermore, an illumination lamp 46 is fixedly installed on the rotating shaft 45. The illumination lamp 46 is used to provide sufficient light source for detection, so that when the motor 44 drives the rotating shaft 45 to rotate between the fixed seats 43, it can drive the illumination lamp 46 to change the angle of the light source.

[0045] Before the test begins, the three-phase energy meter can be positioned using the positioning frame 40. Then, the fixing plate 42 can be driven by the starting cylinder 41 to move the lighting lamp 46 to a suitable position. Then, the motor 44 is started to adjust the light source angle of the lighting lamp 46. After the adjustment is completed, the test head 34 can be started to perform an appearance inspection on the three-phase energy meter.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
