Height Guidance for Lithium Battery Pack Dispensing with Laser Displacement Sensor
Industry pain points and demands
In lithium battery pack assembly, maintaining consistent adhesive application is critical for long-term bonding strength and product reliability.
SinceVision’s SD33 Series laser displacement sensor enables real-time surface height measurement with a guidance error of ≤0.03mm, ensuring accurate dispensing height control.
This precision reduces common defects such as glue shortage, excess, or leakage, directly supporting consistent adhesion quality and downstream production efficiency.
SinceVision Solution: SD33-195 Laser Displacement Sensor
01Ultra-Precise Surface Height Sensing: The SD33 Series sensor captures material surface height data with ≤0.03mm error, ensuring precise control for high-quality adhesive dispensing.
02 Real-Time Feedback for Height Compensation: Continuously measures and feeds back the dispensing height to prevent issues like glue volume inconsistency or missing application areas, improving overall battery pack bonding quality.
03Lower Cost with Comparable Performance: Delivers high accuracy and stability at a competitive cost compared to similar market solutions.
