Description

Technical Field

[0001] The invention relates to the technical field of LED lamp bead substrate welding, and in particular to substrate welding equipment suitable for LED lamp beads. Background Art

[0002] At present, the substrate welding process of LED lamp beads mainly relies on manual operation or semi-automatic equipment. Manual operation has problems such as low production efficiency, prone to human errors, and difficulty in ensuring production stability; although traditional semi-automatic equipment has improved production efficiency to a certain extent, it still has problems such as inconsistent production rhythm, numerous intermediate links, and low thermal energy utilization.

[0003] In the prior art, it is usually necessary to install and transport the substrate multiple times to different equipment for operations such as solder paste coating, LED lamp bead placement and welding, resulting in low production efficiency and difficulty in fully ensuring welding quality, while wasting a lot of energy.
