Problems solved by technology

At present, most methods use hand-held electrostatic discharge devices to move for measurement. Such a moving speed is difficult to grasp, and the judgment of the test discharge distance is also lacking in accuracy and scientificity. The entire test process is still far from perfect.
And at present, the maximum discharge distance of this test can only be measured by experience and ordinary ruler

Abstract

Provided is a test bed for accurately measuring an air discharge distance during electronic static discharge (ESD) of an electromagnetic compatibility test for an automobile part system. The test bed for electrostatic discharge testing comprises a control cabinet and a working table. The control cabinet comprises an industrial control computer, a touch display and a stepping motor controller, wherein the industrial control computer comprises an input / output (IO) control card. The working table is electrically connected with the control cabinet. A longitudinal adjusting device, a horizontal adjusting device installed on the longitudinal adjusting device and a height adjusting device connected to the horizontal adjusting device are installed on the working table. The test bed has the advantages that the air electrostatic discharge distance in the electrostatic discharge test can be accurately measured, the displacement can be read accurately, and the displacement precision is 0.1mm; and the moving speed of an electrostatic discharge device is controlled through a stepping motor, the feeding speed can be accurately controlled, and the national standard requirements of 5mm / s can be met.

Description

technical field [0001] The invention belongs to a test device, in particular to a test bench which can accurately control the feed speed and accurately measure the air discharge distance in the ESD electrostatic discharge of the electromagnetic compatibility test of the auto parts system. Background technique [0002] With the development of the automobile industry, the number of electronic devices on the automobile is gradually increasing, and different electrical appliances will generate electromagnetic interference when they are in use. This interference is classified as EMC electromagnetic interference. Electrostatic discharge is also one of EMC electromagnetic interference. Electrostatic discharge is very destructive. In severe cases, electrical appliances will be burned, resulting in the unusability of automobiles and vehicles. [0003] The current situation is the national standard ISO 10605 and GB / T 19951 "Electric Disturbance Test Method Generated by Electrostatic D...
