其中，图1至图7中给出了本发明实施例的参考方向坐标系，以下结合图1至图7所示的方向，对本发明的实施例进行说明。
本发明的实施例提供了一种输送系统，包括输送载体3、滚床1、驱动机构和定位机构4。
其中，参见图1、图2、图3，输送载体3设有第一连接结构31，第一连接结构31用于与驱动机构配合，从而在驱动机构的作用下沿滚床1输送工件，第一连接结构31与驱动机构的配合关系将在下文中详述。
参见图1、图2、图3、图5，本发明的实施例中，摒弃现有技术中，滚床1通过摩擦力驱动输送载体3的技术方案，将滚床1采用无动力滚床1，滚床1包括滚床底座11和多个滚动部件12，滚动部件12可采用滚轮、辊等，滚动部件12与滚床底座11连接，滚动部件12对输送载体3进行支撑，并能够随输送载体3的运动进行旋转，减少输送运动的阻力。
参见图1、图4、图5，驱动机构包括第二连接结构26和驱动组件，驱动组件能够驱动第二连接结构26沿输送方向在第一位置和第二位置之间往复运动，第二连接结构26在第一位置与第一连接结构31连接，从而实现将驱动组件的动力传递到输送载体3上，第二连接结构26在第二位置与第一连接结构31分离，沿输送方向，第二位置位于第一位置的下游，第一连接结构31与第二连接结构26可采用耦合、搭接等方式，驱动机构和输送载体3之间沿输送方向为第一连接结构31与第二连接结构26形成的刚性接触，可避免传统摩擦驱动方式会受到摩擦极限的限制，而无法进一步提高输送速度的问题，可将标准工位间距6米之间的输送节拍从5秒左右提高到3秒左右。
参见图1、图5，定位机构4安装在对应输送载体3的工作 位置，在输送载体3输送到工作位置时，定位机构4完成输送载体3的定位。其中，定位机构4包括X向定位组件、Y向定位组件和Z向定位组件，其中，X向平行于输送方向，Z向为高度方向，Y向为垂直于X向和Z向的左右方向。X向定位组件用于输送载体3在工作位置的X向定位，Y向定位组件用于输送载体3在工作位置的Y向定位，Z向定位组件用于输送载体3在工作位置的Z向定位，Z向定位组件将输送载体3抬起，以使输送载体3与滚动部件12脱离。
本发明的实施例的动作执行逻辑为：当目前工位的输送载体3要进行输送时，驱动机构的第二连接结构26与输送载体3的第一连接结构31接触，驱动机构执行动作，带动输送载体3输送到下一工位，并通过定位机构4进行定位，然后第二连接结构26与第一连接结构31脱离，驱动机构反向执行动作，带动第二连接结构26返回前一工位，等待下一输送载体3的输送，如此循环。
参见图1，驱动机构可采用皮带式驱动机构2，参见图1、图4，驱动机构包括第一驱动部件21、主动带轮22、从动带轮23和同步带25，第一驱动部件21可采用电机等驱动元件，主动带轮22与第一驱动部件21的输出端连接，主动带轮22、从动带轮23通过同步带25传动连接，同步带25沿输送方向延伸，横跨在工作区域，第二连接结构26与同步带25连接，该实施例中，通过电机正反转，便可实现第二连接结构26的往复运动。
当需要对输送载体3进行输送时，第二连接结构26与第一连接结构31接触，电机转动，实现对输送载体3的驱动，当输送载体3输送到工作位置进行定位后，第二连接结构26与第一连接结构31脱离，电机反向转动，第二连接结构26返回。
进一步的，参见图4，从动带轮23包括第一从动带轮23和第二从动带轮23，第一从动带轮23和第二从动带轮23沿输送方向分布，并将同步带25撑开，横跨在工作区域，主动带轮22位于第一从动带轮23和第二从动带轮23之间，主动带轮22和电机能够偏离滚床1，主动带轮22和电机的布置、维护更加灵活，同时也有效节约了滚床1的空间。此外，主动带轮22两侧设有引导同步带25的辅助带轮24，辅助带轮24用于保证同步带25与主动带轮22有一定贴合，从而使主动带轮22可驱动同步带25。
参见图1，第一连接结构31和第二连接结构26具有相互配合的贴合面，贴合面呈V形或圆柱形，以使第一连接结构31和第二连接结构26能够沿Z向相对运动。在Z向定位过程中，第二连接结构26与第一连接结构31之间可沿两者之间的V形或圆柱形贴合面，在高度方向上相对运动。
在上述实施例的某些实现方式中，在Z向定位过程中第二连接结构26与第一连接结构31自动实现分离，电机反向转动，第二连接结构26返回。
在上述实施例的某些实现方式中，参见图1，同步带25上 设有第二驱动部件，第二驱动部件能够驱动第二连接结构26沿Y向伸缩以与第一连接结构31连接或分离，电机反向转动，第二连接结构26返回。
在上述实施例的某些实现方式中，参见图1，输送系统沿输送方向具有多个工作位置，沿输送方向设置多套皮带式驱动机构2，相邻的两套皮带式驱动机构2的输送范围部分重叠，即沿输送方向，前一套皮带式驱动机构2的第二位置位于后一套皮带式驱动机构2的第一位置的下游，从而实现多工位之间接力式的输送。
参见图5，驱动机构可采用滑台式驱动机构5，参见图5、图6、图7，驱动机构包括滑台座51、齿条55、安装座52和第三驱动部件53，齿条55与滑台座51连接，并沿输送方向延伸。安装座52与滑台座51通过导向组件配合，实现相对运动，第二连接结构26与安装座52连接。第三驱动部件53与安装座52连接，第三驱动部件53的输出端设有与齿条55配合的齿轮54。第三驱动部件53可采用电机等驱动元件，当电机驱动齿轮54转动时，在啮合传动力作用下，可带动安装座52移动，通过电机的正反转，便可实现往复运动。
在上述实施例的某些实现方式中，在Z向定位过程中第二连接结构26与第一连接结构31自动实现分离，电机反向转动，第二连接结构26返回。
在上述实施例的某些实现方式中，参见图7，第一连接结构 31包括销孔35，第二连接结构26包括插销57，还包括第四驱动部件56，第四驱动部件56可采用气缸等驱动元件，第四驱动部件56能够驱动插销57沿Z向伸缩以与销孔35连接或分离。当需要对输送载体3进行输送时，气缸驱动插销57伸出，插销57与销孔35配合，此时电机转动，便可实现对输送载体3的驱动，当输送载体3输送到工作位置进行定位后，气缸驱动插销57退回，此时电机反向转动，便可实现插销57返回。
在输送载体3输送到工作位置时，Y、Z向可实现自动定位，X向则在输送到位后，执行定位动作。
参见图1、图5，X向定位组件包括X向定位轮32、X向定位块41和第五驱动部件，X向定位轮32在输送载体3上限定出X向定位插槽，第五驱动部件能够驱动X向定位块41伸入或退出X向定位插槽。第五驱动部件可采用气缸等驱动元件，当X向定位组件伸出时与X向定位轮32配合，即实现X向定位。
参见图1、图5，Y向定位组件包括Y向定位轮42和Y向定位块33，Y向定位轮42与滚床底座11连接，并沿输送方向分布在输送载体3两侧，Y向定位块33与输送载体3连接用于与Y向定位轮42配合。
参见图2、图3，Z向定位组件包括Z向定位轮43和Z向定位块34，Z向定位轮43与滚床底座11连接，并沿输送方向分布在输送载体3下方，Z向定位块34与输送载体3连接用于与Z向定位轮43配合，当输送载体3在输送过程中，还未输送至与 定位机构4接触时，输送载体3底面与滚轮接触，当实现Z向定位时，输送载体3与滚轮脱离，形成一定间隙D，从而实现Z向自动精定位。
当然，本发明创造并不局限于上述实施方式，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
