| 目的 为了解决现有的纸盒包装生产线上开盒机存在的开盒不可靠、工作稳定性不好的问题，设计一种工作可靠、稳定性较高的纸盒开盒机。方法 分析研究机构的功能要求，采用机构设计方法设计多连杆机构来实现对纸盒的取盒、放盒、开盒工作。采用多刚体动力学约束方程对所设计的开盒机构进行运动学分析。采用ADAMS优化设计模块对开盒机构的各个杆件尺寸进行优化。用SolidWorks软件对所设计的开盒机进行样机设计。结果 用SolidWorks的motion插件对开盒机构进行运动仿真，仿真结果表明，该机构能满足自动开盒功能，运动轨迹与用Matlab求解出的运动方程的轨迹相匹配，验证了数学模型的准确性。用Matlab对优化后的开盒机构运动方程求解，与优化前相比，机构的速度峰值减小了约34%，加速度峰值减小了约75%，机构运行平稳性得到极大改善。结论 所设计的高速开盒机构不仅满足自动开盒功能，而且运行平稳、工作可靠，为纸盒开盒自动化提供了一种适应性更强的开盒方案。 |

| The work aims to design a carton box opener with high working reliability and stability, so as to solve the problems of unreliable opening and poor working stability of box opener in the existing carton packaging production line. The functional requirements of the mechanism were analyzed and studied and the mechanism design method was adopted to design a multi-link mechanism to realize the work of taking, putting and opening the carton. The kinematics analysis of the designed box opening mechanism was carried out by the constraint equation of multi-rigid body dynamics. The ADAMS optimization design module was used to optimize the size of each link of the box opening mechanism. SolidWorks software was applied to design the prototype of the designed box opener. The motion of the box opening mechanism was simulated with the motion plug-in of SolidWorks. According to the simulation results, the mechanism could meet the automatic box opening function and the motion trajectory matched the trajectory of the motion equation solved by Matlab, which verified the accuracy of the mathematical model. When Matlab was adopted to solve the motion equation of optimized box opening mechanism, compared with the mechanism before optimization, the speed peak was reduced by about 34%, the acceleration peak decreased by about 75%, and the smoothness of the mechanism was greatly improved. The designed high-speed box opening mechanism not only meets the functional requirements of automatic opening, but also runs smoothly and works reliably, providing a more adaptable opening program for carton opening automation. |
