Description

technical field [0001] The invention relates to a device that can detect and analyze the charge signal in the environment space of the machine, and can further control the modulation of the ion generator to release more positive ions or negative ions, so as to neutralize the static electricity in the environment space of the machine. It is an electronic component testing and sorting machine that eliminates static electricity by charging and effectively avoids electrostatic discharge during the test process. Background technique [0002] Substances in nature can gain or lose electrons through certain processes (such as friction or induction electrification), and this type of charge is called static electricity. When these positive or negative charges gradually accumulate, a potential difference will be generated with the surrounding environment. The objects with different potentials will cause electrostatic charge transfer between objects through direct contact or electrostat...

AI Technical Summary

Problems solved by technology

As far as the electronic component testing and sorting machine is concerned, the reason why it generates static electricity may be the residual electricity of the electronic component itself or the static electricity accumulated by the friction of the device on the machine during the movement process. In any case, when these static electricity are positive After the charge or negative charge is out of balance and the energy of the potential difference accumulates to a certain extent, once the electronic component is close to or touches the conductor in the process of moving, the so-called electrostatic discharge phenomenon will occur, and this electrostatic discharge phenomenon will result in damage to electronic components during the movement
