电芯模组激光焊接装配线中原料包装箱智能识别上料龙门装置

目的 电芯模组激光焊接装配线上料单位质量大，存在用时长、效率低、上料精准度低的问题，无法满足装配线48 s持续、稳定、精准上料需求，因此基于机器视觉设计一种原料包装箱智能识别上料龙门装置。方法 采用SolidWorks设计龙门上料装置机械结构;基于工艺流程设计电气控制系统;通过机器视觉检测判定包装箱正反以确保正确供料方向;以第1个包装箱视觉检测位置为基准，确定每层4个包装箱的机械手抓取标定位置，并进行偏差补偿，以确定机械手实际抓取坐标;PLC与视觉装置通过TCP通讯，驱动吸盘准确吸取包装箱至入料口。结果 通过实践测试，龙门装置每包装盒上料速度为24~48 s。结论 系统满足装配线供料效率需求，上料精准度明显提升，节约了人力成本。

Intelligent Identification Feeding Gantry Device for Raw Material Packaging Box in Electric Core Module Laser Welding Assembly Line

The work aims to design an intelligent identification feeding gantry device of raw material packaging box based on machine vision to solve the problem that electric core module laser welding assembly line has large unit material weight, long time duration, low efficiency and insufficient feeding accuracy, which cannot meet the continuous, stable and accurate feeding requirements of the assembly line for 48 seconds. The mechanical structure of gantry feeding device was designed by SolidWorks; The electrical control system was designed based on process flow; The positive and negative of the packaging box was determined through machine vision inspection to ensure the correct feeding direction. Based on the visual inspection position of the first packaging box, the grab calibration position of the manipulator of four packaging boxes on each layer was determined, and the deviation was compensated to determine the actual grab coordinates of the manipulator; PLC was communicated with the visual device through TCP to drive the suction cup to accurately suck the packaging box to the feeding port. Through practical test, the feeding speed of each packaging box of the gantry device was 24 ~ 48 seconds. The system meets the feeding efficiency requirements of the assembly line. It significantly improves the feeding accuracy, and saves the labor cost.
