Nylon silk thread service life tester, testing system and testing method

Abstract

The invention discloses a brocade silk yarn life tester, a brocade silk yarn life testing system and a brocade silk yarn life testing method. According to the brocade silk thread life tester, the brocade silk thread can be effectively prevented from being clamped, it can be guaranteed that swing of the brocade silk thread is highly consistent with swing of an actual use scene, meanwhile, the brocade silk thread can generate Ampere force under the action of a magnetic field to swing when current is input, and thus the life of the brocade silk thread is tested; the magnetic field intensity can be adjusted according to needs so as to adjust the stress of the brocade silk threads. According to the brocade silk yarn service life testing system, the service life measurement of the swing speed, the rotating speed, the radian, the angle, the load, the load current and the like of the brocade silk yarn highly conforming to the actual use scene can be realized, the alternate cycle test under more than two test conditions can be realized, and the service life testing precision of the brocade silk yarn is improved. According to the brocade silk yarn service life testing method, testing is carried out based on the brocade silk yarn service life testing system, traditional motor mechanical driving swing is abandoned, and high-precision testing that the height of the brocade silk yarn accords with the use scene can be achieved.

Description

technical field [0001] The invention relates to the technical field of brocade thread detection, in particular to a brocade thread life tester, a test system and a test method. Background technique [0002] The brocade wire set in the speaker is the wire connecting the voice coil and the terminal, which can lead the current into the voice coil. Because one end of the brocade wire of the speaker is fixed on the fixed speaker terminal, and the other end is fixed on the speaker voice coil that moves at high speed with the input signal, during the working process of the speaker, the brocade wire will swing at high speed following the speaker software, so its swing life is related to Horn life and reliability. Therefore, speaker manufacturers usually need to use tests to evaluate the swing life of brocade wire during production, so as to ensure the quality of the speaker. [0003] At present, the brocade thread swing test is generally carried out with a wire swing tester, and i...

Problems solved by technology

[0004] In order to solve the problems of low swing speed, single swing radian, fixed swing load, fixed test load current, and easy damage to brocade wires in the existing motor mechanically driven swing life test method, the brocade wire is connected with the loudspeaker voice coil at high speed and the arc and load are real-time To solve the problem that the actual use scene of the changing swing does not match, the present invention provides a brocade thread life tester
