"Instance" sharing | 3D smart camera can assign precision PIN needle detection: open a new chapter of industrial automation

background knowledge

 The PIN needle is a crucial element in the field of electronic engineering, which specifically refers to the metal pin used in the connector for electrical connection. Such metal pins usually act as electrical conduction and signal transmission in various electronic devices and components. Although the PIN needle is small, its function is extremely critical, and any manufacturing defect or damage may lead to circuit disconnection, signal error or failure.

The traditional manual detection methods are limited by their precision and consistency, and it is difficult to effectively carry out accurate quality inspection of a large number of small and dense PIN needles, which is prone to omission and misjudgment. And 3D visual detection technology to the PIN needle geometric size, shape, position and surface defects of contactless three-dimensional accurate detection, avoid the potential damage to PIN needle, greatly improve the quality of the detection and speed at the same time, effectively prevent the electronic product failure caused by manufacturing defects, further guarantee the quality of the product and long-term stability, for the electronic manufacturing industry has brought substantial technical innovation and production efficiency.
