Description

Technical Field

[0001] The utility model relates to the technical field of heat sink defect detection, in particular to a heat sink surface defect detection device. Background Art

[0002] Heat sink is a device for cooling heat-prone electronic components in electrical appliances. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multiple sheets, etc. For example, the CPU in a computer uses a fairly large heat sink, as do the power tubes, line tubes in a TV, and the power amplifier tubes in an amplifier. In the production process of heat sinks, the presence of internal stress causes waves on the surface, which seriously affects the quality of the heat sink. How to detect and remove the waves from the heat sink surface in a timely manner is a key step to improve its quality and production efficiency.

[0003] At present, manual monitoring is still used in the production of heat sinks. In the process of detecting whether the heat sink has defects, the labor intensity of the staff is too high, which not only damages the eyes but also cannot guarantee a high accuracy rate, and the false detection rate is also high. Using machine vision to detect heat sink defects will effectively reduce the labor intensity of the inspectors, improve the production efficiency of the enterprise, and reduce production costs. In view of the problems of low accuracy and high false detection rate in manual defect detection of heat sinks, a heat sink surface defect detection device is proposed to maximize the accuracy and reduce the false detection rate.
