Description

Technical Field

[0001] The present invention belongs to the technical field of lamp lighting production, and particularly relates to a splitting mechanism for a light source panel. Background Art

[0002] The existing light source panel is composed of multiple light source boards. During the production process, the light source panel needs to be split into multiple light source boards before assembly. The current production process is to put (or convey) the light source panel onto a belt conveyor line through manual labor (or an automatic board loading machine), and then it is split by a splitting component. The light source boards and the light source board strip flow out from another belt conveyor line and wait for subsequent sorting and assembly.
