Problems solved by technology

Wherein, the frequency of the reciprocating motion is determined by the frequency of the reciprocating motion of the drive motor, and its adjustable range is narrow; and since the speed of the reciprocating motion, that is, the linear motion speed of the screw, is determined by the position of the slider of the turntable, , the slider position of the turntable must be adjusted manually, the accuracy is low and the reciprocating movement speed of the slider head of the potentiometer under test cannot be continuously adjusted

Abstract

The invention discloses a potentiometer processing system and a potentiometer processing method, which are applied to a potentiometer life test system. The processing system transmits a control command to a controlling system through an IPC (Industrial Personal Computer), so that the controlling system transmits preset test parameters to a driver according to a pre-stored control procedure; the driver controls a linear motor connected with the driver to linearly move according to the preset test parameters, so as to directly control a sliding head of a tested potentiometer on a testing table connected with the linear motor to do reciprocating motion from the middle position to the two sides of the testing platform, a turnplate and a screw are not needed, and operating steps can be simplified; furthermore, a used linear motor is wide in running frequency and high in accuracy, so as to realize continuously and precisely adjusting the reciprocating motion of the sliding head of the tested potentiometer, and the accuracy for testing the life of the potentiometer can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of potentiometer testing, and more specifically relates to a potentiometer processing system and method. Background technique [0002] In practical applications, the service life of the potentiometer is usually tested before use, that is, the sliding head of the potentiometer to be tested is controlled to reciprocate from the middle position to the left and right sides, and after a certain number of movements, the measured potentiometer is The performance of the potentiometer is tested, and then the performance test result is compared with the performance test result of the standard potentiometer, so as to judge the service life of the potentiometer under test. [0003] Before the performance test of the potentiometer under test, in the prior art, the driver drives the motor and the turntable connected to the motor to rotate, and then the turntable controls the screw to move linearly, so that the screw contr...
