具体实施方式
下面结合实施例对本发明做进一步的详细说明，以令本领域技术人员参照说明书文字能够据以实施。
应当理解，本文所使用的诸如“具有”、“包含”以及“包括”术语并不排除一个或多个其它元件或其组合的存在或添加。
如图1-6所示，本实施例的.一种多工位凸轮搬运机构，包括底板1、设置在底板1中部的转轴2、与转轴2底部驱动连接的电机3、设置于转轴2上部的转盘4、设置在底板1上的安装架5、设置在安装架5上的安装板6、沿凸轮轨迹开设在安装板6底面上的环形状的滑槽7及多个呈环形均匀间隔布置的底部滑动设置在转盘4上且顶部滑动设置在滑槽7内的抓取移栽组件8。
参照图1，安装板6上还设置有用于带动抓取移栽组件8上的抓爪84上下运动的气缸9。电机3用于驱动转盘4转动，转盘4带动抓取移栽组件8在滑槽7的限制下沿凸轮轨迹往复运动；气缸9带动抓取移栽组件8上下抓取。从而使抓取移栽组件8在水平面内的运动轨迹为与滑槽7相同的轮轨迹往，竖直方向为直线，多个工位同时工作，且能避开两个工位之间的障碍物，抓取移栽组件8将产品按凸轮轨迹依次抓取移栽到下一个工位。
参照图1和图5，在一种实施例中，抓取移栽组件8包括呈环形均匀间隔设置在转盘4上的8个，以在转盘4上形成8个抓取移栽工位。滑槽7包括8个呈环形均匀间隔设置的与抓取移栽组件8的位置分别对应的弧形突出部70。
参照图2，抓取移栽组件8包括支架80、设置于支架80底部的水平滑块 81、设置于支架80侧部的竖直滑轨82、滑动设置在竖直滑轨82上的竖直滑块83、设置于竖直滑块83上的抓爪84及设置在支架80顶部的用于配合插设在滑槽7内的轴承85。轴承85沿滑槽7内滑动时，自身边转动，能减小摩擦，便于在滑槽7内的滑动。转盘4上设置有与水平滑块81配合的水平滑轨40。水平滑块81上还连接有水平弹簧86，水平弹簧86的另一端与设置在转盘4上的第一弹簧座41连接(图中示出的为水平弹簧86未与第一弹簧座41安装好的状态)，水平弹簧86一方面能为水平滑块81提供一定的回程动力，使水平滑块81滑动更加顺畅，另一方面能对抓取移栽组件8起到一定的缓冲保护作用。
其中，电机3通过转轴2带动转盘4转动，转盘4再带动其上的抓取移栽组件8转动，而由于抓取移栽组件8顶部的轴承85配合插设在滑槽7内、抓取移栽组件8的底部的水平滑块81则滑动设置在转盘4上的水平滑轨40上，从而使轴承85只能在滑槽7内沿滑槽7形状轨迹滑动，水平滑块81则在水平滑轨40上来回滑动，从而通过滑槽7限制轴承85、水平滑块81与水平滑轨40配合使抓取移栽组件8沿凸轮轨迹往复运动，其运动轨迹与滑槽7的形状轨迹相同，如图所示。
参照图2和图3,安装板6和支架80上均开设有供气缸9下部的驱动杆90穿过的开孔，分别为第一开孔71和第二开孔802；气缸9下部的驱动杆90用于依次穿过安装板6上的第一开孔71和支架80上的第二开孔802，顶压竖直滑块83以在竖直弹簧87的配合下带动竖直滑块83上的抓爪84上下往复运动。支架80上还连接有竖直弹簧87，竖直弹簧87的另一端与设置在竖直滑块83上的第二弹簧座88连接(图中示出的为竖直弹簧87未与第二弹簧座88安装好的状态)。竖直弹簧87一方面能为竖直滑块83提供其向上返回的回程动力，实现竖直滑块83的上下滑动，另一方面能对抓爪84起到一定的缓冲保护作用。
其中，当抓取移栽组件8在水平面内转动时，气缸9下部的驱动杆90向上回缩，从支架80顶板上的第二开孔802中向上退出，避免阻碍抓取移栽组件8的转动；当抓取移栽组件8从上一工位转到下一工位并就位时，支架80顶板上的第二开孔802与安装板6上的第一开孔71正对，气缸9下部的驱动 杆90向下伸出，穿过支架80顶板上的第二开孔802并顶压到竖直滑块83顶部，从而推动竖直滑块83向下运动，竖直滑块83上的抓爪84进行抓取动作，驱动杆90向上回缩后，在竖直弹簧87向上的拉力作用下，将竖直滑块83向上拉到原位，循环往复。
参照图1和图6，底板1表面设置有光电开关10，抓取移栽组件8正下方的转盘4底面上设置有与光电开关10配合的挡板11。挡板11呈L形，其底部的横板12用于与光电开关10上的检测槽配合。即当抓取移栽组件8移动到某一工位就位时，挡板11底部的横板12正好处于光电开关10上的检测槽内，使光电开关10触发信号，进行计数，且能保证工位的精确定位。
参照图4，支架80的侧部还设置有上限位螺柱800和下限位螺柱801，竖直滑块83的侧部设置有处于上限位螺柱800和下限位螺柱801之间的限位挡块830。上限位螺柱800和下限位螺柱801对限位挡块830的上下极限位置进行限位，从而实现对竖直滑块83上下滑动极限位置的限位，一方面保证各工位抓取工作的顺利完成，另一方面能对抓爪84进行保护。
本发明工作原理为：电机3通过转轴2带动转盘4转动，转盘4再带动其上的抓取移栽组件8转动，而由于抓取移栽组件8顶部的轴承85配合插设在滑槽7内、抓取移栽组件8的底部的水平滑块81则滑动设置在转盘4上的水平滑轨40上，使抓取移栽组件8沿凸轮轨迹往复运动。且当抓取移栽组件8在水平面内转动时，气缸9下部的驱动杆90向上回缩，从支架80顶板上的第二开孔802中向上退出，避免阻碍抓取移栽组件8的转动；当抓取移栽组件8从上一工位转到下一工位并就位时，支架80顶板上的第二开孔802与安装板6上的第一开孔71正对，气缸9下部的驱动杆90向下伸出，穿过支架80顶板上的第二开孔802并顶压到竖直滑块83顶部，从而推动竖直滑块83向下运动，竖直滑块83上的抓爪84进行抓取动作，驱动杆90向上回缩后，在竖直弹簧87向上的拉力作用下，将竖直滑块83向上拉到原位，循环往复。即抓取移栽组件8沿凸轮轨迹往复运动的同时，抓取移栽组件8上的抓爪84上下往复运动进行产品抓取和移栽，将产品由一个工位依次移栽到下一工位。
尽管本发明的实施方案已公开如上，但其并不仅仅限于说明书和实施方 式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节。
