Description

Technical Field

[0001] The invention belongs to the technical field of electrical performance detection, and in particular relates to a multi-model thermal battery electrical performance detection system. Background Art

[0002] As a purchased component, thermal batteries need to be strictly tested for electrical performance after entering the factory to ensure that they meet the requirements for use. The test content includes multiple test items such as on-off performance, resistance, and insulation to the ground. The traditional detection method requires operators to use multimeters, electric detonator meters, megohmmeters and other instruments to test the test points on the electrical connector one by one according to the electrical performance wiring relationship of the product. During the detection process, the operator needs to manually connect the pins and measure the resistance value, on-off status and insulation performance between the detection points point by point, and the test results need to be recorded manually. Since different test points have different requirements for test current, different types of detection instruments need to be frequently replaced when testing the same product. In addition, there are differences in the electrical performance wiring relationship of different products, which further increases the complexity of detection. This traditional method is not only cumbersome and inefficient, but also affected by human factors, making it difficult to ensure product quality, especially unsuitable for mass production detection needs.

[0003] In order to meet the needs of mass production, realize intelligent production testing, ensure product quality and improve testing efficiency, a multi-model thermal battery multifunctional testing equipment has been developed. The equipment can automatically complete the electrical performance testing of various models of thermal batteries, effectively solving the problems of low efficiency, easy errors and unstable quality in traditional testing methods, and providing reliable guarantee for mass production of products.

[0016] During the test, the tester parameters are set through the industrial computer, and the logic signal control box is controlled to close the relay switch matrix to form a detection path, read the test value, and obtain the actual resistance value of the product.

[0017] The internal relay switch matrix of the logic signal control box is set to two double-pole switch matrices controlled by the network port, each switch matrix is ​​provided with 64 test points, and the two switch matrices can complete the detection of 128 test points after being cascaded;
