Pressing the module into the pack housing is a critical process in battery pack assembly. The thermally conductive structural adhesive on the bottom of the battery must be uniformly squeezed and spread under continuous, stable force to ensure a thermal interface free of voids and air gaps.
Module compression is a key process in cell-to-module assembly. After cell stacking, precise preload must be applied to compensate for cell swelling during cycling and to ensure module structural stability and cell consistency. Excessive compression can damage the cells, while insufficient compression can compromise cycle life and safety performance.
PACK housing tightening is a key sealing operation, especially with aluminum housings that are sensitive to clamp load. Leetx cordless tightening uses servo closed-loop control and torque-angle monitoring to detect stripped threads, floating screws, and other abnormalities with wireless traceability.
PACK top covers contain many bolts, create missed-tightening risk, and involve sensitive materials. Leetx intelligent tightening with a positioning reaction arm enforces sequence control, prevents missed tightening, supports reaction-force management, and uploads results in real time.
PACK top covers typically require 24-48 bolts, and manual screw picking introduces dropped, wrong, or missed screws. Leetx automatic screw feeding standardizes pick-feed-tighten actions and uses presence confirmation plus error-proof interlocks to eliminate these risks.
Battery module fastening is a safety-critical joint. Long studs pass vertically through the module into the PACK base, requiring controlled engagement depth and verticality; torque plus angle monitoring and seating detection identify stripped threads or abnormal seating while creating per-bolt lifecycle traceability.
