实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
现有技术尚未公开在铆接手机后盖与螺母的过程中,如何控制铆压力度的相关技术。
如图1-6所示,提供铆接载具的实施例,以解决上述技术问题。
其主要结构,包括:机架1、第一定位部2、第一弹性部3、第二定位部4、第二弹性部5和压力传感器6;
第一定位部2与机架1滑动连接并且能够沿着第一方向滑动,第一定位部2包括用于定位第一工件的第一工装21;
第一弹性部3连接机架1和第一定位部2,第一定位部2朝向机架1移动时,第一弹性部3被压缩并且具有沿着第一方向回弹的内力;
第二定位部4与第一定位部2滑动连接并且能够沿着第一方向滑动,第二定位部4包括用于定位第二工件的第二工装41;
第二弹性部5连接机架1和第二定位部4,第二定位部4朝向机架1移动时,第二弹性部5被压缩并且具有沿着第一方向回弹的内力;
压力传感器6设置在机架1和第二弹性部5之间,压力传感器6用于检测第二弹性部5被压缩时施加在机架1上的作用力。
本实施例中,第一方向以竖直方向为示例,第一工件(图中未出示)以手机后盖为示例,第二工件以螺母为示例。
铆压机(图中未出示)自上而下地对第一定位部2施加压力,使得第一定位部2向下移动,进而使得第一工装21带动第一工件向下移动并且靠近第二工件,第一工件对第二工件施加向下的作用力,以使得第一工件与第二工件铆接为一个整体,压力传感器6实时检测第二定位部4承受的压力,机架1的旁侧布置有传感器控制仪61,传感器控制仪61用于实时显示压力传感器6检测到的压力,供工作人员调整铆压机的输出力,避免铆压力度过大,造成第一工件或者第二工件损坏。
通常情况下,铆压力度位于规定的范围内,铆压机的铆压头移动至最大行程时,第一弹性部3和第二弹性部5均处于压缩状态,铆压机的铆压头复位后,第一定位部2和第二定位部4通过第一弹性部3和第二弹性部5的弹力复位。
需要时,还可以在铆压机的铆压头的旁侧设置压板,压板伴随着铆压头同步升降,铆压头与第二工件接触之前,压板与第一工件接触,第一工件被压板和第一定位部2夹持在中间,然后第一工件、压板、第一定位部2同步下降,更进一步地固定了第一工件,避免其在铆接的过程中损坏。
进一步地:常规技术中,用于检测第一工装21是否装夹有第一工件时,通常使用漫反射式光电开关,但是漫反射式光电开关容易受到第一工件的材质的影响,往往不能正常功能工作,例如,手机后盖是透明玻璃的。
为此,本实施方式提供一种用于检测第一工装21是否装夹有第一工件的可选实施例,如图1、2、3、6所示,其具体结构如下所述。
第一定位部2包括用于检测第一工件的真空检测模组,所述真空检测模组包括吸盘81、真空泵82和真空度传感器;
吸盘81穿过第一定位部2延伸至第一工装21的工作区间;
真空泵82用于抽吸空气,真空泵82的抽吸端连接吸盘81;
真空度传感器设置在吸盘81和真空泵82之间,所述真空度传感器用于检测吸盘81内部的真空度。
第一工装21夹持第一工件之后,真空泵82启动,通过真空度传感器检测吸盘81是否吸附有第一工件,若真空度较低,则说明第一工装21未夹持有第一工件。
具体的:本实施方式提供一种机架1、第一定位部2和第二定位部4之间的滑动连接结构的可选实施例,如图5、7、8、10所示,其具体结构如下所述。
如图7、8、10所示,机架1包括底板11和竖板12,其中底板11水平设置并且可以在生产线中移动,竖板12竖直固定在底板11上,竖板12上形成有沿着竖直方向延伸的多个第一滑槽13,第一定位部2上形成有与第一滑槽13滑动连接的第一滑块23,其中,第一滑槽13与第一滑块23均为T字形状;
如图5所示,第一定位部2的内部形成有沿着竖直方向延伸的多个第二滑槽24,第二定位部4包括与第二滑槽24滑动连接的第二滑块42;
如图10所示,竖板12上形成有限制第二定位部4向上滑动的行程的第一止动件14,第一定位部2上形成有限制第二定位部4向下滑动的第二止动件25。
第一定位部2向下移动的过程中与第二定位部4无接触,使得第一工件可以在移动足够长的行程之后再与第二工件铆接,使得本实施方式可以用于铆接轴向距离较长的螺母。
第二定位部4向下移动至一定的距离之后能够与第一定位部2接触,并且带动第一定位部2向下移动,使得第一弹性部3能够为第二定位部4提供缓冲作用,同时保护第二弹性部5不被压坏。
进一步地:如图5、7和8所示,本实施方式提供一种第一弹性部3的可选实施例,其具体结构如下所述。
第一弹性部3包括垫板31、导柱32和第一弹性件33;
垫板31水平设置在底板11的上方,第一定位部2与垫板31固定连接;
导柱32竖直设置在底板11的边缘并且与垫板31滑动连接;
第一弹性件33连接底板11和垫板31并且处于压缩状态。
具体的,第一弹性件33是矩形弹簧,竖板12、第二定位部4、第二弹性部5和压力传感器6均不与垫板31接触。
具体的:本实施方式提供一种机架1和第二弹性部5之间的滑动连接结构的可选实施例,如图9所示,其具体结构如下所述。
机架1和第二弹性部5通过浮动减震座7连接,浮动减震座7包括:第三滑块71、第四滑块72、第二弹性件73和第三止动件74;
第三滑块71与机架1滑动连接并且能够沿着第一方向滑动,第三滑块71通过第二弹性部5连接第二定位部4;

第三止动件74连接第三滑块71和第四滑块72,并且使得第三滑块71和第四滑块72之间具有最大滑动距离。
第二弹性部5通过浮动减震座7与机架1滑动连接,使得第二弹性部5能够竖直向下移动,进而使得第二定位部4承受的压力能够通过第二弹性部5和浮动减震座7完整地传输至压力传感器6。
同时,第三滑块71和第四滑块72具有相互远离的运动趋势,并且能够伸缩一定的距离,使得浮动减震座7形成了一个弹簧减震器,铆压结束后,铆压机移出铆压作用力时,第二定位部4在第二弹性部5的回弹作用下竖直向上移动以复位,第二定位部4与第一止动件14碰撞而停止向上移动,因碰撞产生的振动通过第二弹性件73消除,避免第二定位部4与第一止动件14的碰撞对压力传感器6产生较大的冲击。
具体的,如图9所示:第三滑块71是圆柱套筒形状,第三滑块71的底端形成有径向朝内延伸的环状凸缘711;
第四滑块72包括推板721和第一滑柱722,推板721是圆盘形状并且与第三滑块71的外径相同,第一滑柱722与环状凸缘711滑动连接,推板721与压力传感器6的检测端接触,第一滑柱722具有内螺纹孔;

第二弹性件73是碟簧,第四滑块72通过第一滑柱722与第三滑块71滑动连接,并且通过第二弹性件73和垫片限制第四滑块72的滑动行程。
进一步地:若第三滑块71在振动中自行出现转动,则第三止动件74与第一滑柱722的螺纹连接很容易松动,为此,本实施方式提供一种可选实施例,如图9所示,其具体结构如下所述。
第三滑块71的顶端形成有径向朝外延伸的止旋滑块712,机架1上形成有沿着竖直方向延伸并且与止旋滑块712滑动配合的止旋滑槽15。
止旋滑块712与止旋滑槽15滑动连接后,第三滑块71不能旋转,第三止动件74与第一滑柱722的螺纹连接也就不容易松动。
进一步地:本实施方式中,如图5和9所示,第二定位部4、第二弹性部5和浮动减震座7之间的一种可选的连接结构如下所述。
第三滑块71是圆柱套筒形状,第三滑块71的轴向长度大于第二弹性部5的工作行程;
第二定位部4包括竖直设置的第二滑柱43,第二滑柱43的顶端与第二滑块42连接,第二滑柱43的底端穿过第二弹性部5延伸至第三滑块71的内部,第二滑柱43靠近自身底端的部位固定安装有第一垫片44和第二垫片45,第一垫片44和第二垫片45将第二弹性部5夹设在中间。
