Double silver brush intelligent anti-static electric screwdriver

Abstract

The double-silver brush intelligent anti-static electric screwdriver disclosed by the present invention includes an electric screwdriver driving part, a connecting seat, a coupling and a casing, and also includes an antistatic main shaft, and the output shaft of the electric screwdriver driving part passes through the inner hole of the connecting seat And lock it on the flat end with screws, the inner hole end of the coupling is locked on the output shaft of the electric batch drive part, the opening slot of the anti-static main shaft is stuck on the flat end of the coupling, the shaft sleeve of the anti-static main shaft Insert the outer side of the connecting seat and lock it with screws. The electric batch driving parts, connecting seat, coupling and anti-static main shaft are installed in the shell. The intelligent anti-static electric screwdriver with double silver brushes of the present invention utilizes double silver brushes to contact the high-speed rotating main shaft, so that the grounding resistance of the main shaft and the casing is very small, so that the main shaft and the casing are grounded, and the static electricity on the main shaft is exported to the The grounded shell acts as an intelligent anti-static function to protect electrical components.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an intelligent anti-static electric screwdriver with double silver brushes. Background technique [0002] The electric screwdriver is also called an electric screwdriver and an electric screwdriver. It is an electric tool for tightening and loosening screws. It is mainly used in assembly lines and is one of the necessary tools for most manufacturing companies. So far, in the electronics industry (flashlights, computers, small appliances, medical, automotive, aviation, military, etc.), many electronic components such as PCBA, IC, and transistors are used. These electronic components are usually fastened with screw locks. At present, in the process of using the traditional electric / pneumatic screwdriver to lock the screw, static electricity will be generated and lead to PCBA, IC or transistor breakdown, damage (injury), poor function or shortened life, etc., which can...

AI Technical Summary

Problems solved by technology

So far, in the electronics industry (flashlights, computers, small appliances, medical, automotive, aviation, military, etc.), many electronic components such as PCBA, IC, and transistors are used. These electronic components are usually fastened with screw locks. At present, in the process of using the traditional electric / pneumatic screwdriver to lock the screw, static electricity will be generated and lead to PCBA, IC or transistor breakdown, damage (injury), poor function or shortened life, etc., which cannot meet the technical requirements and industry 4.0. The development trend, especially in the high-tech industry, the anti-static requirements are more prominent

[0003] The traditional electric screwdriver has no anti-static function. The common anti-static method uses a grounding wire or an anti-static bracelet. Workers wear an anti-static bracelet when they are working, which is very inconvenient and not reliable.

In addition, there is a copper sleeve electric batch that can be used for anti-static, but the electric batch that uses the copper sleeve as the rotation guide is prone to heat and wear in the high-speed rotating working environment, the electric batch has a short service life, low accuracy, and the anti-static effect is not ideal.

[0004] Because the use of traditional electric batch or copper sleeve electric batch lock PCBA board can not effectively prevent the damage of electronic components caused by static electricity, and cannot meet the development trend of Industry 4.0
