As a key exterior component of vehicle bodies, the automotive B‑pillar demands strict standards for paint flatness, glossiness and surface fineness. During production spraying and rework processes, minor scratches, orange‑peel texture, gloss loss and granular blemishes tend to occur on B‑pillar surfaces. Fine polishing is mandatory to meet the exterior requirements for finished vehicles. Currently, most automobile manufacturers still rely on conventional manual polishing, which comes with noticeable process drawbacks.

Traditional manual polishing with hand‑held tools heavily depends on operators’ experience, featuring high labor intensity and low production efficiency. Inconsistent pressure and irregular moving paths in manual operations frequently result in uneven polishing, over‑polished paint surfaces and missed polishing at edges and corners. This leads to poor product consistency and high rework rates. Besides, substantial dust generated in polishing pollutes the workshop environment and poses severe health hazards to workers. Manual polishing can hardly satisfy the requirements of modern‑day mass production and workplace safety.

Targeting prominent pain points in automotive B‑pillar polishing, Truman has rich experience in auto‑parts surface treatment and independently developed the Automotive B‑pillar Surface Automatic Polishing Workstation. Built around an industrial robot and equipped with a full set of self‑developed intelligent software and hardware, the workstation enables intelligent and fully‑automated polishing operations.

The workstation accurately identifies B‑pillar curved profiles and paint blemishes, and automatically generates polishing trajectories. It adaptively adjusts polishing pressure and speed to fully cover flat areas, curved surfaces as well as intricate edges and corners. Paint defects are effectively removed for uniform and delicate gloss across B‑pillar surfaces. Free from the downsides of manual work, standardized automatic operations greatly boost polishing precision and working efficiency, and guarantee stable product quality consistency. Adopting an enclosed dust‑free working design, the equipment optimizes workshop conditions, reduces labor expenses and workpiece scrap loss. It provides an efficient, stable and eco‑friendly intelligent solution for exterior polishing procedures of automotive B‑pillars.
