具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式 来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
参阅图1，本发明一实施例提供的毛刺检测装置10用于对工件20上是否存在毛刺进行检测，工件20以呈长轴状的海绵辊21为例进行说明，该毛刺检测装置10包括相对设置的相同两个夹紧机构11，在进行检测时，海绵辊21的两端分别与夹紧机构11相抵接，从而使得海绵辊21被夹置在两个夹紧机构11之间。
同时参阅图1至图5，夹紧机构11包括支架100、抵紧件200、第一感应件300、滑动组件400和第二感应件500。抵紧件200和第一感应件300均固定在支架100上，抵紧件200用于与海绵辊21相抵接，第一感应件300通过支架100与抵紧件200连接，滑动组件400滑动套设在抵紧件200上，滑动组件400上设置有配合孔421，海绵辊21的端部与该配合孔421配合，即插置在配合孔421中。第二感应件500安装在滑动组件400上，当滑动组件400没有受力而处于初始状态时，在滑动组件400的滑动方向(水平方向)上，第一感应件300与第二感应件500之间保持设定间距。
在一些实施例中，抵紧件200和滑动组件400均为同轴设置的回转体零件。抵紧件200包括抵紧杆210，抵紧杆210固定在支架100上并沿水平方向延伸，参阅图2，抵紧杆210的端部能够穿设在滑动组件400的配合孔421中，即在初始状态下，抵紧杆210的端部和海绵辊21的端部两者相抵接并均位于配合孔421中，通过配合孔421的限位导向作用，使得抵紧杆210和海绵辊21之间能够快速形成稳定可靠的抵接关系。第一感应件300为光电传感器310，第二感应件500为感应板510。当然，在其它实施例中，抵紧件200 和滑动组件400也可以为其它非回转体零件等；第一感应件300可以为感应板510，第二感应件500为光电传感器310。
参阅图1和图4，在滑动组件400上施加足够的作用力，以期使该作用力带动滑动组件400朝向海绵辊21方向滑动的前提下，显然，该作用力为方向指向海绵辊21的推力或拉力，此时，支架100、光电传感器310、抵紧杆210和海绵辊21在水平方向上静止不动。当该作用力无法驱动滑动组件400相对海绵辊21滑动以带动感应板510经过光电传感器310时，海绵辊21存在毛刺。参阅图3和图4，当该作用力能够驱动滑动组件400相对海绵辊21滑动以带动感应板510经过光电传感器310时，海绵辊21存在毛刺。当然，滑动组件400相对抵紧杆210和海绵辊21滑动时，即海绵辊21相对配合孔421滑动，否则，海绵辊21相对配合孔421不滑动。所谓感应板510经过光电传感器310，即滑动组件400带动感应板510逐渐靠近光电传感器310，并使感应板510位于光电传感器310的正下方，两者之间在水平方向上的间距为零，此时，光电传感器310将被激发而感应生产电平信号。
在一些实施例中，当海绵辊21的端部存在毛刺时，该海绵辊21的端部可以与配合孔421形成过盈配合关系，或者卡扣在该配合孔421中，即海绵辊21与滑动组件400过盈连接或卡扣连接，使得上述作用力无法克服海绵辊21与滑动组件400之间的连接力，导致滑动组件400无法相对抵紧杆210和海绵辊21产生滑动，继而无法带动感应板510经过光电传感器310。当海绵辊21的端部不存在毛刺时，海绵辊21的端部与该配合孔421形成间隙配合关系，当上述作用力施加在滑动组件400上时，海绵辊21与滑动组件400之间仅存在较小的摩擦阻力，故该作用力能克服摩擦阻力并使滑动组件400相对抵紧杆210和海绵辊21产生滑动，继而能够顺利带动感应板510经过光电传感器310。
参阅图4和图5，在一些实施例中，滑动组件400包括滑动主体410和毛刺套420，滑动主体410整体式设计，滑动主体410滑动套设在抵紧杆210上，毛刺套420固定安装在滑动主体410中，配合孔421开设在毛刺套420 上，即海绵辊21的端部插置在毛刺套420中。
在一些实施例中，滑动主体410分体式设计，滑动主体410包括缸体411和套筒412，感应板510安装在套筒412上，毛刺套420设置在套筒412靠近工件20的一端，缸体411与套筒412远离工件20的一端之间具有弹性压力：
例如，缸体411开设有密封腔411a，密封腔411a中容纳有压缩气体，压缩气体能形成适当的压力，套筒412远离工件20的一端收容在密封腔411a中、并与缸体411滑动配合。换言之，带压力的压缩气体相当于气弹簧，套筒412相当于缸筒的活塞筒。当海绵辊21的端部存在毛刺时，由于海绵辊21与毛刺套420过盈连接或卡扣连接，施加在缸体411上的作用力无法推动套筒412和毛刺套420相对海绵辊21滑动；但是，缸体411可以克服压缩气体的压力朝向海绵辊21运动适当距离，当作用力撤销后，在气体压力的推动下，缸体411将返回初始位置。此外，当待检测的海绵辊21在与配合孔421配合的过程中，如果海绵辊21的端部存在毛刺，海绵辊21与毛刺套420之间的连接力将使得套筒412挤压压缩空气而远离海绵辊21运动(即向后运动)，压缩气体可以起到一定的缓冲作用，避免海绵辊21在夹置的过程中损坏整个装置。
再如，可以采用压缩弹簧替代压缩气体，压缩弹簧连接在缸体411密封腔411a的底部和套筒412之间。同样地，压缩弹簧可以产生与上述压缩气体类似的效果，在此不再赘述。
参阅图4和图5，在一些实施例中，缸体411的全部内壁面411a、套筒412的部分内壁面412a均能够与抵减件接触，这样可以对缸体411和套筒412的运动起到很好的导向作用，同时，套筒412的另一部分内壁面412b与抵紧件200之间保持设定间隙，在套筒412的运动过程中，该另一部分内壁面412b与抵紧件200之间不存在摩擦力，避免摩擦力过大而对套筒412和抵紧杆210形成磨损。此外，也便于将套筒412的端部伸入缸体411的密封腔411a中，确保安装的便捷性。
参阅图2和图5，在一些实施例中，滑动主体410的套筒412具有面向海绵辊21设置的第一端面412c，毛刺套420具有面向工件20设置并位于套筒412之外的第二端面422，第一端面412c与第二端面422可以保持设定间距A，即毛刺套420相对套筒412朝海绵辊21方向凸出适当长度，使得毛刺套420的配合孔421在水平方向上存在合理延伸长度，当海绵辊21的端部存在毛刺时，以便海绵辊21的端部与配合孔421存在合理的接触面积，进而形成足够稳定的过盈连接或卡扣连接关系，以防止毛刺套420带动套筒412朝向海绵辊21滑动，最终避免感应板510经过光电传感器310。
当对海绵辊21的端部进行是否存在毛刺的检测实验时，根据整个海绵辊21长度的变化，两个夹紧机构11可以相互靠近或远离，使得整个毛刺检测装置10能夹置不同长度的海绵辊21，从而适合对不同长度类型海绵辊21的检测，提高毛刺检测装置10的通用性。当海绵辊21的两端分别插入毛刺套420的配合孔421中、并与抵紧杆210抵接后，对海绵辊21的装夹程序已完成。接着，可以朝海绵辊21方向推动缸体411，如果缸体411无法带动套筒412和毛刺套420相对海绵辊21滑动，即海绵辊21无法相对配合孔421滑动，套筒412和毛刺套420静止不动，套筒412将无法带动感应板510靠近光电传感器310以激发电平信号，由于没有检测到电平信号，故可以判断海绵辊21的端部存在毛刺。当推动缸体411时，缸体411能带动套筒412和毛刺套420相对海绵辊21滑动，即海绵辊21能够相对配合孔421滑动，套筒412将带动感应板510逐渐靠近光电传感器310、直至感应板510位于光电传感器310的正下方，此时，光电传感器310激发出电平信号，通过检测到该电平信号，由此可以判断海绵辊21的端部不存在毛刺。
对于该毛刺检测装置10，只需将海绵辊21的端部与毛刺套420的配合孔421配合，并对缸体411施加朝向海绵辊21的作用力，最终通过套筒412是否能够带动感应板510经过光电传感器310以激发电平信号，从而判断海绵辊21的端部是否存在毛刺，这样消除了振动力的影响，减少了调试时间，提高了检测精度和效率。
请参阅图1和图6，本发明还提供一种毛刺检测方法，该方法可以通过上述毛检测装置10来实现，该毛刺检测方法主要包括如下步骤：
S610，第一步，固定设置第一感应件，并在滑动组件上设置第二感应件。
S620，第二步，将工件的端部与滑动组件上的配合孔相配合。
S630，第三步，对滑动组件400上施加朝向工件20中部的作用力，当工件20不能相对配合孔421滑动并无法使第二感应件500经过第一感应件300而产生感应信号时，判断工件20存在毛刺；当工件20能够相对配合孔421滑动以使第二感应件500经过第一感应件300而产生感应信号时，判断工件20不存在毛刺。
在一些实施例中，当工件20存在毛刺时，使配合孔421与工件20形成过盈配合关系；当工件20不存在毛刺时，使配合孔421与工件20形成间隙配合关系。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
