An aluminum foil TV characteristic leakage current testing device

Abstract

The invention discloses an aluminum foil TV characteristic leakage current testing device, which belongs to the technical field of aluminum foil testing and comprises an aluminum foil testing component, and an automatic immersion mechanism is arranged on the top of the aluminum foil testing component. In the present invention, through the mutual cooperation of the designed aluminum foil test assembly, automatic immersion mechanism, locking assembly and positioning assembly, the aluminum foil on the back plate clamp is more gentle in the process of entering the test liquid, so it can be detected The change of the relevant test data during the process of the aluminum foil entering the test liquid, and the use of the buffer effect, also effectively ensured the stability of the test liquid level, thereby effectively improving the test accuracy, and because the gravity ball is always in a vertical state in a static state In this way, the level alignment of the aluminum foil test tank can be quickly realized. By increasing the level of the test liquid inside the constant temperature test tank, the degree of correlation between the aluminum foil and the test liquid during the entry process can be realized to be the same, which effectively improves the test accuracy.

Description

technical field [0001] The invention belongs to the technical field of aluminum foil testing, in particular to an aluminum foil TV characteristic leakage current testing device. Background technique [0002] Aluminum foil is the main material of aluminum electrolytic capacitors, its quality directly determines the quality of capacitors, because aluminum foil accounts for nearly 80% of all material costs of capacitors. There are many kinds of aluminum foil manufacturing processes today, the production cost of aluminum foil is also different, and the performance also has its own characteristics. If the electrical performance indicators of aluminum foil can be fully and objectively reflected through effective testing equipment, choose the appropriate aluminum foil among many specifications. The aluminum foil produced by the enterprise is very important. [0003] For example, the "Intelligent Aluminum Foil TV Characteristic Tester" (publication number: CN2771870) published by C...
