Monitoring device and monitoring method of electrostatic eliminator

Abstract

The invention discloses a monitoring device and a monitoring method of an electrostatic eliminator. The monitoring device comprises an electrostatic measurement sensor (10), an electrostatic measurement controller (11) and a programmable logic controller (12), wherein a charged board (101) of the electrostatic measurement sensor (10) neutralizes charged ions generated by the electrostatic eliminator (16); the electrostatic measurement sensor (10) collects neutralization data; the electrostatic measurement controller (11) is used for supplying voltage for the charged board (101) of the electrostatic measurement sensor (10) and supplying control signals for the electrostatic measurement sensor (10), and analyzes the neutralization data; and the programmable logic controller (12) is communicated with the electrostatic measurement controller (11), and controls an alarm device whether to send an alarm signal based on an analysis result of the electrostatic measurement controller (11). With the adoption of the monitoring device and the monitoring method of the electrostatic eliminator, the performance state of the electrostatic eliminator can be monitored effectively; the manpower and the time are saved; and the cost is lowered effectively.

Description

technical field [0001] The invention relates to a monitoring device of a static eliminator and a monitoring method thereof. Background technique [0002] In industrial production, static electricity is often generated on products through friction and contact, and its harm is obvious to all. Now, more and more manufacturers are beginning to take various measures to eliminate static electricity in the production process of products. For example, in the field of liquid crystal display, during the production process of liquid crystal display panels, the static electricity on the surface of the glass substrate will adsorb the dust particles in the surrounding environment on the surface of the glass substrate, thus causing pollution and electrostatic barriers, and it is also very easy to damage the glass substrate The circuit on it will affect the performance of the product and cause losses. In order to eliminate static electricity on the surface of the glass substrate, a static...

Problems solved by technology

[0003] At present, the detection of the performance of the static eliminator in the production process is usually carried out by the operator holding a hand-held static measuring instrument, and regularly tests the performance of the static eliminator at fixed points. This process is time-consuming and laborious, which greatly increases the cost.
