Module Pressing & Steel-Belt Fitting, and Insulation Inspection
On battery module PACK lines, module pressing with steel-belt fitting, terminal photography, and insulation testing are critical stations before laser welding.
On Huiyao Laser prismatic battery module PACK lines (power and energy storage), three stations before laser welding are especially important: module pressing & steel-belt fitting, terminal photography, and module insulation inspection.
Module pressing & steel-belt fitting
Function: press the module and tightly fix the module to end plates with steel belts for stability and safety.
Typical process: place module and end plates on the press fixture → press to a set dimension → fit the steel belt so the assembly is firmly strapped → release and transfer.
Value: reliable contact between module and end plates; steel-belt fixation improves structural integrity and reduces loosening or damage in transport and use.
Terminal photography station
Uses high-resolution cameras to capture full terminal images for measurement and defect checks, then passes data downstream to laser welding.
Benefits: fast non-contact inspection, accurate micro-defect detection, and traceable inspection records.
Module insulation inspection
High-precision insulation testers measure insulation resistance quickly and accurately to judge whether the module meets electrical safety criteria before further processing.
