Description
Technical Field

Background
Automated Optical Inspection (AOI) is a device that detects common defects of a workpiece (e.g., perforations, boundary dimensional anomalies, surface blemishes) based on optical principles. When the automatic detection is performed, the AOI detection device automatically scans the workpiece through the camera, acquires an image, compares the image with qualified workpieces in the database, and detects the defects on the workpiece through image processing.
For the existing detection methods of double-sided detection, one is to clamp a workpiece to be detected by a clamp and then turn over (for example CN 213275395U), so as to realize double-sided detection, however, for some fragile hollowed-out etched parts, for example a hollowed-out circuit board or a mobile phone cooling fin as shown in fig. 1, in the AOI detection process, a plurality of cooling fins 16 are not separated from a raw material plate 17 (i.e. in the AOI detection process, the whole of the cooling fins 16 and the raw material plate 17 is used as a workpiece), the cooling fins 16 and the raw material plate 17 are only connected by a plurality of connection points 18, and the raw material plate itself is thinner (usually about 0.2mm-0.4 mm), and the double-sided detection is very easy to deform in the clamping process to crack the connection points, so that the cooling fins fall off from the raw material plate and further damage the workpiece is caused; the other is that the workpiece to be detected is supported and simultaneously detected through the AOI detection device by arranging a transparent window on the supporting plate without clamping (such as CN 211426316U), however, the method is applicable to double-sided detection of fragile hollowed-out etched parts, but the workpiece in the previous procedure is required to be placed on the supporting plate by adopting a manual or special instrument, the workpiece is required to be placed at a feeding position in the next procedure after detection, and the continuity of the procedure is difficult to realize and the operation efficiency is low.
