Machine features
Diodes are divided into rectifier diodes, power diodes, voltage regulator diodes, varactor diodes, light-emitting diodes, photodiodes, etc. according to their uses.

The visual inspection of the diode by the optical automatic inspection machine is mainly on the body and the pin bracket, and focuses on the detection rate. Xianlian Technology has an AOI+AI detection solution that can improve the detection rate of products, combining the respective expertise of AOI and AI for detection, so as to maximize the detection rate.

In addition, TFCT also has a tube model, which can conduct six-sided visual inspection of the materials in the tube. The six-sided inspection speed is much higher than other turret-type models and the detection rate is high.

vibration feeding track
The vibration feeding has an open track, no upper cover, no side cover, fast feeding without material jam.
OK material boxes
Two OK large material boxes in the front can be automatically switched when full (the machine does not need to stop)
light resource difference
Add two stations to set up different light sources to inspect different defects.
AI detection interface
AI inspection makes up for the shortcomings of traditional algorithms.
