中文摘要:
      目的 为Roll-to-Roll薄膜自动烫装拉链设备设计一种模切机构,以实现薄膜模切虚线任务。 方法 设计一种由偏心轴滑块机构及可移动切刀机构组成的模切机构,机构由伺服电机驱动。建立模切机构的动力学模型,通过粒子群算法优化机构参数,减小机构往复运动惯性力,从而减小由于惯性力产生的振动,降低伺服电机控制难度;在Adams中优化模切机构,设计减振装置柔性连接滑块与切刀机构,对模切机构的减振性能进行进一步优化。结果 偏心距为7 mm、连杆圆心距为82 mm时,机构往复运动的惯性力比优化前最大减小了21.47%,偏心轴滑块机构因惯性力产生的振动减小。减振体设计为直径50 mm,高度20 mm的丁腈橡胶块,切刀机构位移变化量为0.41 mm小于0.5 mm,满足设计要求。切刀机构x向加速度变化幅度减小,y向加速度突变消失,振动明显减小。结论 薄膜自动烫装拉链设备模切机构惯性力小,工作稳定可靠,易于伺服电机控制。
英文摘要:
      The work aims to design a die-cutting mechanism for roll-to-roll film automatic melting and assembling zipper equipment to achieve the function of dotted die-cutting lines on the film. A die-cutting mechanism composed of an eccentric shaft slider mechanism and a movable cutter mechanism was designed and driven by servo motors. A dynamic model of the mechanism was established. The particle swarm algorithm was used to optimize the mechanism parameters to reduce the inertial force of the reciprocating motion of the mechanism, thereby reducing the vibration caused by the inertial force and the difficulty of controlling by servo motor. The die-cutting mechanism was optimized in Adams, and a damping device to flexibly connect the slider and the cutter mechanism was designed to further optimize the damping performance of the die-cutting mechanism. The inertial force of the mechanism reciprocating motion was reduced by 21.47% at the maximum when the eccentricity was 7 mm and the connecting rod center distance was 82 mm, and the vibration of the eccentric shaft slider mechanism due to the inertial force was reduced. When the damping bodies were designed as nitrile rubber blocks with a diameter of 50 mm and a height of 20 mm, the displacement change of the cutter mechanism was 0.41 mm, which was less than 0.5 mm, which met the design requirements. The changing range of acceleration in x-direction of the cutter mechanism was reduced, and the sudden changing of acceleration in y-direction disappeared. The vibration of cutter mechanism was reduced. The die-cutting mechanism of roll-to-roll film automatic melting and assembling zipper equipment has small inertia force. It works stably and reliably. It is easy to be controlled by servo motor.
