Glue Dispensing Detection for String Welding Machines in Battery Cell Testing

Industry pain points and demands

After the battery cells are manufactured, battery cells with the same or similar performance can be connected in series through a string welding machine. During this process, glue dispensing operations will be performed at the main grid electrode and the fine grid electrode. The glue height needs to be tested to ensure that the glue completely covers the main grid to fix it.

• Glue Height Accuracy: Improper glue height may lead to incomplete coverage of the main grid, resulting in weak fixation and compromised electrical connections.

• Precision Challenges: Traditional inspection methods often lack the resolution and speed required to assess the glue’s top surface and contour details accurately.

• High-Volume Production: Efficient and stable detection systems are necessary to meet the demands of large-scale photovoltaic manufacturing.
