1.Introduction
With the popularization of machine vision, machine vision has been widely used in the new energy industry, Lithium battery electrode tab detection is also widely needed. Electrode tab is a thin metal sheet, easy to wrinkle, tilt... so we should pay more attention to the lighting model selection. Here we introduce the lighting model selection for battery electrode tab inspection through some cases.

LTS-HPR100-W 
LTS-3COX50-WCase 2
(1)Work piece picture
(2)Inspection requirement：FOV 40*50mm, to inspect the solder of electrode tab, to highlight the solder joint and contour of electrode tab.
(3)Mechanism and effect

Reason：Use LTS-3DM116-W and LTS-3COX40-W together to inspect the solder, uniformity light, slight tilt can also be stable imaging, LTS-COX8050-R can distinguish the contour and front.
Case 3
(1)Work piece picture
(2)Inspection requirement：FOV 20*30mm, inspect the end face of electrode tab and location.
(3)Mechanism and effect

LTS-RN7400-B
Reason：The use of a smaller low-angle ring light avoids reflections from the white background and highlights the white outline of the electrode tab.
That's all for today's sharing. Thank you for your support. See you next time.
