04. 自动化作业逻辑 / Operation Logic
01. 待机与逻辑预检： 操作员将待处理导轨放置于精密治具后，通过物理按键触发启动序列。系统首先调用底层 I/O 逻辑，实时检索治具在位传感器状态。若未检测到工件或装夹到位信号，系统将立即挂起作业并触发 **“工件未就位”** 显示报警，确保设备运行安全。
Standby & Pre-check Logic: After placing the guide rail into the precision fixture, the operator triggers the start sequence. The system first invokes I/O logic to verify the fixture sensor status. If no workpiece or clamping signal is detected, the operation is suspended with a "Workpiece Not Detected" alarm to ensure safety.
02. 视觉特征检索与寻位： 预检通过后，高分辨率 CCD 工业相机快速移动至预设特征区进行抓拍。视觉算法（Vision Engine）通过提取图纸定义的特征点位（如定位孔特征 [cite: 1]），计算出导轨当前的实际空间坐标。系统随后将视觉偏移量实时补偿至运动控制算法中，实现从“理论位置”到“物理实测位置”的精准映射。
Vision Feature Retrieval: Upon successful pre-check, the high-resolution CCD moves to the predefined area for image capture. The vision engine extracts feature points defined in the drawing [cite: 1] to calculate the actual spatial coordinates. The system then applies real-time vision offsets to the motion control algorithm for precise mapping from theoretical to physical position.
03. 高阶插补与路径喷涂： 在获取精准坐标后，三轴运动模组执行 **S曲线平滑路径** 算法。喷油嘴在复杂空间长曲面上保持恒定的合成速度（Feedrate），配合动态流体控制，确保油脂均匀涂敷于导轨轮廓。整个喷涂轨迹无停顿、无震动，完美适配精密导轨的剖面结构要求。
High-order Interpolation & Spraying: After acquiring precise coordinates, the 3-axis motion module executes S-curve path smoothing. The nozzle maintains a constant feedrate across the complex spatial curves, synchronized with dynamic fluid control to ensure uniform lubrication. The entire trajectory is seamless and vibration-free, matching the rail's profile requirements.
