Abstract

The invention discloses optical detection equipment for a network transformer. The optical detection equipment s used for solving the problem of low quality inspection efficiency of pins of the network transformer in the prior art, and realizes the purpose of improving the quality inspection efficiency of the network transformer by adopting a photoelectric method. When the network transformer stays on a track in an inspection disk for quality inspection, the network transformer receives equal illumination intensities on both sides. When the pins of the network transformer are intact and qualified, light ray intensities reflected to two sides by means of each pin are equal, and no dazzling light spot exists in an image captured by means of an image acquisition device arranged just above theinspection disk. If the pins are in a curved or bent state, the fact that the pins of the network transformer are defective is apparent from a quick look. The optical detection equipment can even seta program to perform exposure intensity analysis on the image, so as to perform quality inspection on the pins of the network transformer automatically, thereby greatly improving the quality inspection efficiency of the pins of the network transformer.

Description

technical field [0001] The invention relates to the field of network transformers, in particular to an optical detection device for network transformers. Background technique [0002] Network transformers, also known as data pumps, network isolation transformers, etc., filter the differential signals output by the PHY with differential-mode coupled coil coupling to enhance the signals, and couple them to the other end of the network cable through electromagnetic field conversion. When any CMOS process chip is working, the signal level generated is always greater than 0V (depending on the chip process and design requirements), and the PHY output signal will have a large DC component loss if it is sent to a place of 100 meters or even longer. . Moreover, if the external network cable is directly connected to the chip, electromagnetic induction and static electricity can easily cause damage to the chip. Furthermore, the grounding method of the equipment is different, and the ...
