Abstract

The present invention discloses a network transformer automatic detection device, which is used to solve the problem of low quality inspection efficiency of network transformer pins in the prior art to achieve the purpose of improving quality inspection efficiency of a network transformer through a photoelectric method. When the network transformer stays on a track in an inspection disk to performquality inspection, the light intensity on both sides is equal. When the network transformer pins are perfectly qualified, the intensity of light reflected by the pins to two sides is equal, and no glaring spot appears in an image captured by an image acquisition device directly above the inspection disk. If the pins are bent or buckling, the defects of the network transformer pins can be spottedon first sight. The network transformer automatic detection device can even perform exposure intensity analysis on the image through set-up program, thereby automatically performing quality inspection on the network transformer pins, hence quality inspection efficiency of the network transformer pins is greatly improved.

Description

technical field [0001] The invention relates to the field of network transformers, in particular to an automatic 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 th...
