Problems solved by technology

Although this test method can ensure that the anti-static wrist straps worn by workers work normally when they are on the production line, there are also some obvious problems. Bad, loose wearing (poor contact between the wrist and the wrist strap), damage to the physical properties of the wrist s

Abstract

The invention provides an antistatic wrist band monitor. The monitor comprises a wrist band contact sensing module, a comparison module and a control module. The wrist band contact sensing module is used for acquiring the capacitance value between an antistatic wrist band and the skin, and the resistance value between the antistatic wrist band and the ground. The comparison module is electrically connected with the wrist band contact sensing module and is used for comparing whether the acquired capacitance value and the acquired resistance value are in set values respectively. The control module is electrically connected with the comparison module and used for generating a control signal when judging that the antistatic wrist band is abnormally worn according to results given by the comparison module. Thus, real-time monitoring on working states of the antistatic wrist band is achieved.

Description

technical field [0001] The invention relates to the technical field of static electricity protection, in particular to a monitor for monitoring the real-time working status of an antistatic wristband. Background technique [0002] In the middle of the 20th century, with the rapid development of industrial production and the rapid popularization and application of polymer materials, the wide application of some polymer materials with high resistivity such as plastics and rubber products, as well as the high-speed modern production process, made Static electricity can accumulate to a very high level in industrial production, and thus produce electrostatic hazards that can cause quite serious consequences and losses. In the production field of electronic products, soft and hard breakdowns caused by electrostatic discharge (ESD, Electro-Static Discharge) will bring great losses to the electronics manufacturing industry every year. In view of this, as one of the main anti-static...
