Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of visual inspection, and particularly relates to an adsorption structure of a light-emitting carrier. BACKGROUND

[0002] In the modern electronic manufacturing field, a carrier is a key support and connection carrier for various electronic components, and the quality yield of the carrier directly determines the performance and reliability of electronic products. With the development of electronic products towards miniaturization and high performance, strict requirements are put forward for the manufacturing precision and quality control of the carrier. In the manufacturing process of the carrier, small defects, short circuits, open circuits and the like easily affect the performance of the carrier.

[0003] With the development of machine vision detection technology, part of the detection system based on machine vision is applied to carrier detection. Due to the thinness of the carrier, a back light type detection scheme of a light source, i.e. a light-emitting carrier (a light source is arranged below a glass carrier), is derived on the basis of the traditional machine vision detection system. However, the back light type detection scheme is interfered with in the horizontal direction by the suction hole on the bearing surface of the carrier, and the light line forms a shadow after passing through the suction hole when the back light source is upwardly illuminated, thereby affecting the detection precision of the carrier.

[0004] Therefore, the researchers add a side light source to the original light-emitting carrier to increase the brightness of the hole and reduce the hole shadow. However, the existing light-emitting carrier usually directly leads out the air extraction pipeline from the side along the horizontal moving direction of the glass carrier, so that the air extraction pipeline interferes with the side light source during the horizontal sliding of the glass carrier.
