How CK_Label_V3 Pick-to-Light System Works
The CK_Label_V3 simplifies warehouse operations through a clear “Receive → Guide → Pick → Confirm” workflow.
When the warehouse system sends a picking task:
1. Receive Task
The warehouse label receives data from the router through wireless communication and displays important information on the E-Ink screen, such as:product name,material number,storage location,quantity,Barcode / QR code.
Operators can immediately understand the picking requirement without checking paper lists.
2. Light-Guided Location Finding
The built-in LED indicator provides visual guidance, allowing operators to quickly identify the correct picking location among thousands of products.
The multi-color LED indicator can highlight different statuses, such as:picking instruction,task confirmation,abnormal reminders
This greatly reduces searching time and improves picking efficiency.
3. Pick and Confirm
After completing the picking task, operators simply press the confirmation button on the label.
The action is sent back to the warehouse management system, updating the picking status instantly.
This creates a closed-loop picking process with fewer mistakes and better inventory accuracy.
