Description
Technical Field
The invention relates to the technical field of detection, in particular to an electric component detection device and method.
Background
Currently, electrical components place high demands on sealability and insulation. Taking the cabinet door of the energy storage cabinet as an example, in the production process of the cabinet door of the energy storage cabinet, in order to ensure the quality and the safety of products, air tightness detection and insulation voltage resistance test are required. Wherein insulation detection is a test of paramount importance for verifying whether the insulation properties of the cabinet meet standard requirements.
Some products with high insulation requirements need to be subjected to insulation voltage-withstanding detection for many times before leaving factories so as to ensure the accuracy and reliability of detection results. Specifically, in the conventional method for performing the insulation and voltage withstanding test a plurality of times, a plurality of identical test stations are arranged on a production line and the test is repeated a plurality of times. This detection method wastes a lot of time in the joining process, resulting in reduced efficiency and increased production and time costs.
Disclosure of Invention
The present invention aims to solve one of the technical problems in the related art to a certain extent. Therefore, the invention provides an electric component detection device, which changes the detection gap by adjusting the air pressure, so that multiple insulation and voltage withstand tests are performed at the same station, the connection process before detection is not required to be repeated, and the time is saved.
The invention further provides a detection method of the electric component detection device.
The technical scheme adopted by the invention is as follows: provided is an electrical component inspection device including:
a work table;
A control unit;

Since the change in air pressure causes the density of air to change, when the air pressure increases, the air density increases and the collision frequency between air molecules increases, so that the insulating ability of air increases. Conversely, when the air pressure is reduced, the air density is reduced, the collision frequency between air molecules is reduced, and the insulation ability is reduced. Therefore, in the same-level insulation/pressure-resistance test, the higher the air pressure, the smaller the test gap between the test terminal and the insulator under test. By utilizing the characteristics, the invention can detect the air tightness of the workpiece by the detection device and simultaneously detect the insulation and voltage resistance of the workpiece under different air pressure environments. The air pressure in the buckle cover can be adjusted by controlling the air inlet and the air outlet of the pressurizing air passage, so that the detection gap of the insulation detection mechanism is changed. Under the high-pressure environment, the detection gap between the detection end of the insulation detection mechanism and the insulator to be detected is reduced, and the insulation performance can be detected more accurately. And under the low-pressure environment, the detection gap is increased, so that the device can be used for detecting the condition of poor insulation performance. By conducting insulation voltage-resistant detection under different air pressure environments, the insulation performance of the electric component can be more comprehensively evaluated, and the accuracy and reliability of detection are improved. Compared with the prior art, the invention realizes the insulation and voltage-resistant detection of the workpiece at the same station, and the connection process before repeated detection and the labor cost are not needed. In a word, the invention provides a high-efficiency, accurate and reliable electric component detection device, and has wide application prospect.
