 本发明的实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
如图1至5所示，多工位回转式微型探针全自动卷边机，包括机台1，机台1上设有旋转台2，旋转台2上设有多个用于夹持探针100的夹持工装21，多个夹持工装21沿旋转台2转动方向形成上料工位30、卷边工位40和下料工位60，机台1上位于上料工位30的旁侧设有上料机构，上料机构用于将探针送料至上料工位30，具体为，上料机构包括上料盘31、上料机械手32和上料夹头701，用于盛装卷边探针的上料盘31安装于机台1上，且位于上料工位30的旁侧，上料夹头701设置于上料机械手32的自由端，并经上料机械手32驱动将探针由上料盘31送料至上料工位30，机台1上位于卷边工位40的旁侧设有切割机构41和定位机构42，定位机构42抵接于探针的上端对探针在竖直方向定位，定位机构包括下压气缸421和下压头422，下压头422设置于下压气缸421的自由端，并经下压气缸421驱动下移抵接于卷边工位40内探针的上端，使探针在竖直方向上保持稳定，切割机构41包括切割部和旋转部，旋转部驱动经竖直方向定位后的探针自转，具体为，旋转部包括升降气缸418、旋转电机419和磁铁（图中未示出），旋转电机419设置于升降气缸418的自由端，磁铁设置于旋转电机419的自由端，升降气缸418驱动磁铁上升与夹持工装相吸附，夹持工装21包括底座211、轴承套212、铁质旋转套213、定位套214和护套215，底座211上设有第一通孔210，旋转台2上设有与第一通孔210同轴的第二通孔（图中未示出），铁质旋转套213可转动的安装于轴承套212内，该铁质旋转套213的底端位于第一通孔210处被磁铁吸附，定位套214固定于铁质旋转套213内，该定位套214内安装有用于插装探针的护套215，结合探针顶端被下压头下压，因此探针可相对稳定的安装于护套内，其可随护套同角度转动，因而可以实现旋转电机419驱动磁铁转动带动铁质旋转套和探针同轴旋转，使探针产生自转动作；切割部包括驱动组件和成型刀416，驱动组件包括升降电缸411、回转气缸412、同步轮413、同步带414和刀座415，回转气缸412安装于升降电缸411上并经驱动上下移动，回转气缸412通过一对同步轮413驱动同步带414移动，一对刀座415相错位的固定于同步带414相对两侧，成型刀416安装于刀座415内，一对成型刀416经同步带414带动平移对自转的探针进行切割，即通过两个成型刀在探针的两侧对正在自转的探针进行切割，完成卷边动作。
探针卷边的具体过程为：位于护套内的探针顶端被下压头压住，升降气缸带动旋转电机上移，旋转电机自由端的磁铁吸附铁质旋转套，从而由旋转电机驱动铁质旋转套转动，实现探针自转；同时，升降电缸工作，驱动回转气缸下降，至成型刀与探针上需卷边位置相同高度，由于一对成型刀错位设置，且初始位置避开成型刀所在位置，因此成型刀可以下降至需卷边处位置高度，回转气缸驱动同步轮带动同步带上的刀座产生水平方向上的位移，使得一对成型刀在探针两侧对自转的探针进行切割，完成卷边动作；升降气缸动作，使得磁铁与铁质旋转套脱离，下压头上升，升降电缸动作，使得成型刀上升至设定高度，通过旋转台转动将完成卷边的探针送料至下一工位，并将上料工位的探针送料至卷边工位。
机台1上位于下料工位60的旁侧设有下料机构，下料机构将卷边后的探针移离夹持工装，下料机构包括下料框61、下料机械手62（与上料机械手结构相同）和下料夹头（与上料夹头结构相同），下料框61安装于机台1上位于下料工位60的旁侧，下料夹头设置于下料机械手62的自由端，并经下料机械手驱动将探针由下料工位60送料至下料框61。
切割部还包括导轨417和微调旋钮4151，微调旋钮4151设置于刀座415上用于调节成型刀416的位置，即用于调节成型刀的端部伸入程度，从而控制卷边成型的深度，刀座415可滑移的设置于导轨417上，保证刀座带动成型刀移动的精准度。
还包括检测机构，旋转台2上位于卷边工位40和下料工位60之间具有检测工位50，机台1上位于检测工位50旁侧设有检测机构5，检测机构包括驱动气缸51和测力器52，测力器52设置于驱动气缸51的自由端，该测力器52下压于检测工位50内的探针上用于检测探针回弹力。
上料机构上设有第一视觉检测CCD，通过视觉定位拍摄材料位置，确认坐标后由上料机械手抓取产品，再由上料视觉定位上料工位的位置坐标，上料机械手把抓取好的产品放入上料工位；下料机构上设有第二视觉检测CCD 63，通过视觉定位后由下料机械手进行产品抓取，如果产品力是合格的，产品会放入对应工位的下料框，如果产品力不合格，会直接放入不合格料盒里面。
