Description

Technical Field

[0001] The invention relates to the technical field of SIC pin-tooth substrate detection, and in particular to an automatic detection system for visual appearance of SIC pin-tooth substrate coding. Background Art

[0002] SIC pin-tooth substrate is a substrate with a pin-tooth structure, usually made of silicon carbide material, with the main characteristics of high hardness, high temperature resistance, good chemical stability, excellent electrical insulation, etc. The main application areas are mechanical transmission, electronic device packaging and heat dissipation. In the field of mechanical transmission, it can be used as a core component in precision gear transmission, using its high hardness and wear resistance to improve the transmission efficiency and service life of the gear. For example, in some high-precision robot joint transmission, gears made of this substrate can reduce transmission errors and improve the robot's motion accuracy. In the field of electronic device packaging: Due to its good electrical insulation and thermal stability, it is often used as a packaging substrate for electronic devices. For example, in the packaging of power semiconductor devices, SIC pin-tooth substrates can provide support and heat dissipation channels for chips, help dissipate the heat generated by the chip when it is working, and improve the reliability and performance of the device. The automotive-grade SIC module pin-tooth substrate has high requirements on the external dimensions in the subsequent packaging process. If the pin-tooth distribution and external dimensions of the substrate do not meet the requirements, it will cause assembly interference. In the field of heat dissipation: the pin-tooth structure increases the heat dissipation area, which is beneficial to the dissipation of heat. In some devices with high heat dissipation requirements, such as high-end computer graphics cards, servers and other heat dissipation components, the SIC pin-tooth substrate can be used as a heat dissipation substrate to effectively reduce the operating temperature of the equipment and ensure the normal operation of the equipment.

[0003] When producing SIC pin-tooth substrates, it is necessary to check whether the SIC pin-tooth substrates have obvious macroscopic defects such as cracks, scratches, missing corners, pores, inclusions, etc. For the pin-tooth part, it is necessary to carefully check whether the pin-tooth is complete and whether there is any bending or breaking.
