In-depth analysis of high-precision modular welding line for light truck body-in-white
DUOYUAN has built an overall solution for the light truck body-in-white welding line for a leading commercial vehicle company, and has achieved full-chain delivery of process planning, equipment manufacturing, installation and commissioning through the EPC general contracting model. The project integrates core technologies such as modular production line design, ±0.2mm welding positioning, and flexible switching of three models. The welding pass rate of key mating surfaces has exceeded 98%, and the space utilization rate has increased by 40%, setting a new benchmark for intelligent manufacturing of commercial vehicles.
Four core values drive intelligent manufacturing transformation
✅ Modular EPC service: process planning/equipment integration/debugging and maintenance full-process delivery ✅ Millimeter-level welding accuracy: Panasonic welding system + pneumatic clamps achieve ±0.2mm repeat positioning ✅ Three-dimensional space revolution: 5.7-meter double-layer platform design releases 40% of ground production capacity space ✅ Zero-cost upgrade reservation: wide-body body interface + process transformation reservation to achieve the lifelong value of the production line
Technical Analysis
▍ Flexible conveying system Electric hoist + sling realizes three-dimensional aerial transfer of body in white, and four-mode control system (automatic/semi-automatic/manual/maintenance) can be switched freely
▍Black technology of assembly station Panasonic automatic welding can realize automatic welding of welding points that the lower welding gun cannot enter, and high-precision pneumatic clamp group realizes synchronous positioning of side panel/bottom plate
▍Breakthrough in door cover line efficiency Turntable hemming workstation: 1 robot completes hemming of double-sided doors, and the three-station hemming head (pre-wrap/actual wrap/finger wheel) has an accuracy of ±0.2mm
▍Space optimization design Cable tray/control cabinet are fully deployed on top, ground maintenance channel is widened by 50%, and aerial inspection platform realizes 15-minute response to equipment failure
▍Future expansion capability The fourth model interface is reserved for the main line tooling
