Static electricity elimination reminding device

Abstract

The invention discloses a static electricity elimination reminding device which comprises a shell, an RC network, a microprocessor, a static electricity removing board, a wrist strap, a relay K1, a relay K2, an indicator light and a knob switch. The RC network and the microprocessor are installed inside the shell, the indicator light and the knob switch are installed on the outer side of the shell, the static electricity removing board is connected with one end in the middle of a resistor and a capacitor of the RC network, the other end of the resistor is connected with a power source, and the other end of the capacitor is grounded. The wrist strap is connected to the end, connected with the RC network, of the static electricity removing board through a wire. The static electricity elimination reminding device solves the ignorance problem of a traditional static electricity device, greatly improves the use ratio of an electrostatic device in a factory, and reduces economic losses caused by static electricity in the production process.

Description

Technical field [0001] The invention relates to a prompting device, in particular to a static elimination prompting device that uses static elimination as the right to enter a production workshop. Background technique [0002] The static charge builds up to generate static electricity. Charge transfer occurs when static-charged objects contact zero-potential objects or objects with potential differences. This phenomenon is called electrostatic discharge. The electrostatic voltage induced by the human body is above 2-4KV, usually due to It is caused by slight movements of the human body or friction with insulators. [0003] With the rapid development of electronic products, electronic product processing and manufacturing have prospered. In the production process of electronic products, the electrostatic potential carried by the human body contacts the IC, which will cause damage to the contact IC and cause economic losses. At the same time, the damage to the IC by static electricity...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of electronic products, the processing and manufacturing of electronic products are booming. During the production of electronic products, the electrostatic potential carried by the human body comes into contact with the IC, which will cause damage to the contact IC and cause economic losses. At the same time, the damage of static electricity to the IC is not only In the manufacturing process of electronic components, it also exists in the process of IC assembly and transportation. Static electricity is not removed in time or completely, resulting in serious electrostatic damage. Therefore, removing static electricity from the human body has become a processing and production process in the electronics industry. necessary steps in

[0004] A common antistatic plate is connected to the ground through a wire, and the charge of the human body is introduced into the ground through the metal plate and the wire. The operator can eliminate static electricity by touching the metal plate with his hands. However, when the operator enters the production workshop, due to negligence or For other reasons, it is easy to forget to touch the static electricity removal device or the correctness of the touch cannot be guaranteed, which will bring hidden dangers to the processing and production of electronic products, and may cause electronic components to be damaged by static electricity, resulting in product damage or failure, affecting work efficiency and increasing production costs
