[0001] The present application relates to the technical field of lighting devices, in particular to a conveying device for LED substrates and a dispensing system. BACKGROUND

[0002] With the development of lighting technology, LED lighting has emerged. In the process of manufacturing LED, dispensing operation is a crucial link.

For example, manual picking operation is low in efficiency, and the precision of manual dispensing is difficult to guarantee, which is prone to problems such as glue overflow and glue leakage; although semi-automatic equipment improves production efficiency to a certain extent, it still cannot meet the demand of large-scale and high-efficiency production.
