Abstract
Description
Technical Field
[0001] The utility model relates to the field of testing devices, in particular to an anti-static testing device for packaging bags. Background Art
[0002] The surface resistance tester is an instrument for testing the surface resistance value of an object. It is mostly used in the fields of microelectronics, medicine, aerospace and precision machinery. It is used to quantitatively measure the surface resistance or system resistance of all conductive, antistatic and electrostatic discharge materials. It is simple to use and easy to carry. Just place it on the surface of the object to be tested and press the red button. The indicator light on the instrument ranges from 10^3 to 10^12Ω, and one of the LED lights will light up according to the test value. This instrument can be used to measure the surface specific resistance (surface resistivity) of various fabrics, carpets, films and other insulating materials. The size of the surface specific resistance can indirectly reflect the length of static leakage time on the surface of the test material, thereby reflecting the static performance of the test material.
[0003] In the prior art, some anti-static packaging bags for electronic products are usually tested with a surface resistance tester after production and processing to ensure that the packaging bags have anti-static function. After placing the tested packaging bag on an insulating platform, the inspector holds the surface resistance tester and contacts the test electrode on the bottom with the surface of the packaging bag. Then, the inspector presses the switch button to detect whether the packaging bag has anti-static function according to the indicator light that lights up. However, after the anti-static performance of the packaging bag is tested with the existing surface resistance tester, due to the lack of protection measures for the test electrode on the bottom of the surface resistance tester, the test electrode is very likely to touch other objects when the surface resistance tester is carried or operated in other ways after use, which may cause wear and damage to the test electrode. The next time the packaging bag is tested with the surface resistance tester, the detection operation and the normal use of the surface resistance tester will be affected. Utility Model Content
