As power battery production scales rapidly, lithium-ion battery PACK lines face growing demands. Traditional gantry robots struggle with cycle times. Manual adhesive application can lead to inconsistent yield. And switching between different cell specifications can make production changes slow and complex.
QKM’s AP Series heavy-payload parallel robots are designed to address these challenges—with high speed, precise control, and the flexibility required for high-volume battery production.
▍Lithium-Ion Battery PACK Adhesive Application: 0.33 s/Cycle
Heavy-payload parallel robots are designed for high-precision, high-payload, high-speed production.
In lithium-ion battery PACK production, adhesive application is a critical process that directly affects packaging quality and battery safety. It requires a combination of precision, speed, and flexibility.
QKM was among the first to deploy its AP15X and AP25X heavy-payload parallel robots in PACK adhesive application, overcoming the traditional trade-offs between speed and precision associated with gantry robots, SCARA robots, and manual operations.
▍The Solution: Redefining Adhesive Application with Speed, Precision and Stability
