The prompt
Create a SolidWorks-style CAD concept sheet for an automatic A4 paper stapling machine based on the attached reference. Show isometric, top, front, right-side, and exploded feed-path views with dimensions and a compact BOM. Overall size: 380 W × 400 L × 190 H mm. A4 paper: 210 × 297 mm. Use a 12° inclined bottom-feed stack tray, friction pickup roller under the stack, separator pad, pinch rollers, two rope conveyors, adjustable side guides, and a servo-driven stopping pin that batches exactly three sheets. Replace the writing head with an electric desktop stapler. Staple the top-right corner, 15 mm from the top and right edges. Add hold-down plate, optical sensors, control box, and inline collection tray 35 mm below the platform, sloped for gravity discharge, capacity 25 sets. Label the paper path: bottom feed → pinch rollers → rope conveyor → three-sheet stop → staple → lower tray. Include a numbered BOM: frame, stack tray, pickup roller, separator pad, pinch rollers, rope conveyors, servo stop, electric stapler, hold-down plate, guides, collection tray, sensors, servo, control box. Clean white background, blue/gray technical drawing style. Title: AUTOMATIC A4 THREE-SHEET STAPLING MACHINE — CONCEPT ASSEMBLY. Add note: CONCEPT ONLY—VALIDATE BEFORE MANUFACTURING.
