Abstract

The invention discloses an automatic test apparatus for friction voltage, comprising a stand and a test device. A pedestal is arranged on the lower part of the stand; the stand is provided with a friction device for performing friction on tested samples on the pedestal; the friction device comprises a friction member in contact friction with the tested samples on the pedestal, and a first driving mechanism for driving the friction member to move; the test device is used for testing friction voltage of the friction member, generated on the tested samples, and comprises a static test instrument and a second driving mechanism for driving the static test instrument to move; and the friction device and the test device are connected with a control device for controlling the actions of the friction device and the test device. The automatic test apparatus realizes the full automation of a friction electrification portion and the test device, and ensures the accuracy and repeatability of a test result as well.

Description

Technical field [0001] The invention relates to a friction voltage test equipment, which is especially suitable for testing the friction voltage of clean room consumables. Background technique [0002] Friction voltage is the static voltage caused by electron transfer between objects rubbing each other. In the production workshops of electronics, optical fibers, semiconductors, precision instruments, aerospace and flat panel displays, it is necessary to strictly control the friction voltage of clean consumables (especially high-end clean clothes, wipes, etc.) to avoid excessive friction voltage of consumables Discharge static electricity to electronic components, causing damage to the product. The standard 12703.5-2010 adopts a rotating friction voltage test equipment. The base is equipped with a rotating drum driven by a motor. Four bumps are evenly distributed on the wall of the rotating drum, and the sample is fixed on the bumps. The standard abrasive is rubbed with the samp...
