摘　　要：天然橡胶在现代社会中占据着重要的地位,但是其获取主要依靠人工割胶,劳动强度大、生产效率低;目前国内外仍未研制出携带方便、使用简单、结构精炼、成本低廉的全自动智能化割胶设备;为了提高产胶效率,改善胶工工作条件,提出一款便携式自动割胶机器人的设计方案;在半覆盖复合式割胶机器人的基础上进行提质升级,抱紧机构改为开合结构,提高了对不同树径胶树的适应性;切削运动机构实现了对胶槽螺旋切割轨迹的任意调节;通过分析刀具的受力情况,确定刀具最优切入角;经过ANSYS仿真验证,该便携式自动割胶机器人结构设计精良,具有一定的实用价值。The acquisition of natural rubber mainly depends on artificial tapping,which has high labor intensity and low production efficiency.In order to improve the efficiency of glue production and improve the working conditions of glue workers,a design scheme of a portable automatic rubber cutting robot is proposed.The upgrading is based on the semi-covered compound rubber cutting robot.The clamping mechanism is changed to the opening and closing structure,which improves the adaptability to different tree diameter gum trees.The cutting movement mechanism realizes the arbitrary adjustment of the spiral groove cutting path.By analyzing the force of the tool,determine the optimal cutting angle of the tool.After ANSYS simulation verification,the structure of this portable automatic tapping robot is well-designed and has certain practical value.
