Description

用于将磁盘驱动器悬架夹紧到致动器臂的悬架夹
技术领域
背景技术
磁盘驱动器包括通过围绕枢轴旋转致动器臂在磁盘上方致动的磁头。磁头通常安装在通过万向支架联结于悬架远端的滑动块上,其中悬架联结于致动器臂的远端。理想的方式是,例如,将测试悬架数量作为质量控制程序的一部分以确保悬架的采样批次满足特定设计规格。若足够的悬架不能通过质量控制程序,那么可以修改悬架制造过程以便纠正这个问题。当测试悬架时,快速地将悬架夹紧到测试站(例如,合适的旋转支架或基于磁盘驱动器的测试站)的致动器臂上或快速地将悬架从测试站的致动器臂上松开是期望的,以便最大化测试程序的吞吐率。

具体实施方式
图1A-1C示出用于将磁盘驱动器悬架4夹紧到致动器臂6的悬架夹2。图2示出根据本发明实施例的悬架夹2的分解视图,其包括具有可操作用于偏置闭锁构件12的弹簧10的外壳8,其中闭锁构件12围绕枢轴14可旋转。在压缩弹簧10和以第一方向旋转闭锁构件12后,闭锁构件12可操作通过使弹簧10解压/松弛而将悬架4夹紧到致动器臂6。
在图2的实施例中,悬架夹2的弹簧10包括形成贝氏弹簧(或盘形弹簧)组16的多个贝氏垫圈(Belleville washer)。垫圈18将压缩力施加到贝氏弹簧组16,如下所述。图2的悬架夹2进一步包括具有圆柱体14的帽20,其中圆柱体14穿过闭锁构件12的孔以及穿过垫圈18以及贝氏弹簧组16的孔被插入。圆柱体14的内室被穿透用于接收如图3A的横截面视图所示的将帽20固定到外壳8的螺钉22。图2中所示的闭锁构件12包括穿过帽20的孔插入的致动销24,其用于如下所述围绕帽20的圆柱体14旋转闭锁构件12。
当悬架夹2被置于致动器臂6上时,在图1A-1C、图2以及图3A中示出的悬架夹2包括在致动器臂6的销26A和26B上方滑动的孔。如图3A中所示,销26A和26B包括允许闭锁构件12在槽内旋转的槽28A和28B。参考图2,闭锁构件12包括狭缝30A和30B,并且帽20包括允许致动器臂的销26A和26B滑动通过的狭缝32A和32B。帽20包括孔34A和34B,并且闭锁构件12包括允许推进销穿过和施加压缩力到垫圈18的相应孔,从而如图3A中所示压缩贝氏弹簧组16(为清楚起见,推进销未示出)。
在将悬架夹2置于致动器臂6上并如图3A中所示压缩贝氏弹簧组16之后,使闭锁构件12围绕帽20的圆柱体14顺时针旋转。在一个实施例中,转移工具的驱动销致动闭锁构件12的销24,以便围绕圆柱体14旋转闭锁构件12。参考图3B,在闭锁构件12旋转时,闭锁构件的至少一部分滑动到销26A和26B的槽28A和28B中。当使贝氏弹簧组16松弛时(通过释放推进销),闭锁构件12啮合槽28A和28B内的销26A和26B,从而如图3B所示将悬架4夹紧到致动器臂6。
为了将悬架4从致动器臂6松开,压缩力被施加到垫圈18以便压缩贝氏弹簧组16,接着,闭锁构件12围绕圆柱体14旋转(以相反方向)直到闭锁构件12的狭缝30A和30B与销26A和26B的槽28A和28B对齐。接着,悬架夹2可以从致动器臂6脱离,以及在下面描述的实施例中,使用执行贝氏弹簧组16的压缩和闭锁构件12的旋转的转移工具。
在上述的实施例中,悬架4首先被夹紧到悬架夹外壳8的远端,接着,悬架夹外壳8如图1A所示被夹紧到致动器臂6。在另一个实施例中,悬架夹外壳8可以,例如利用合适的注塑成型技术,与悬架4整合在一起。在一个实施例中,悬架夹2可用于将悬架4夹紧到合适测试站的致动器臂6上,例如旋转架或基于磁盘驱动器的测试站。当被安装到磁盘驱动器生产线中时,悬架4可以从悬架夹外壳8被松开,并利用不同的夹紧技术联结到磁头组装配生产线的致动器臂上。在替代实施例中,用于将悬架夹紧到测试站的致动器臂的悬架夹2也可以用于将悬架夹紧到磁盘驱动器生产线的致动器臂上。
在一个实施例中,转移工具用于将磁盘驱动器悬架4安装到致动器臂6上。图4A示出转移工具36的例子,其在将悬架4夹紧到致动器臂6之前,紧握悬架4并将悬架4置于致动器臂6上。图4B示出在将悬架4夹紧到致动器臂6后的转移工具36状态,以及图4C示出已经从悬架4脱离后的转移工具36。
在一个实施例中,转移工具36包括可操作用于致动推进销40A和40B(图5A)以压缩悬架夹2的弹簧10的第一致动器38(图6)和可操作用于致动驱动销44(图5A)的第二致动器42(图7A),其中用于围绕枢轴旋转悬架夹2的闭锁构件12的驱动销44在上面参考图2、3A和3B描述。
图5A示出转移工具36的实施例,其包括由滑动凸轮48(图4C)致动以便握紧悬架4的夹持臂46A和46B。在图4C的实施例中,滑动凸轮48由操作杠杆组件50的用户致动,以便如图4C中所示沿转移工具36的长度围绕托架52滑动该滑动凸轮48。
图4C示出在握紧悬架以便安装到致动器臂上之前,处于解锁状态的转移工具。滑动凸轮48包括分开的隆起物,并且在隆起物沿夹持臂46A和46B的轴承54A和54B滑动时,隆起物使夹持臂46A和46B转动。当夹持臂46A和46B的基端分开时,如图5B所示远端彼此朝对方缩短。此外,第一致动器38(图8A)收缩推进销40A和40B,以及第二致动器42(图8A)旋转驱动销44到图5B中所示的解锁位置。
在用户旋转杠杆组件50到如图4C所示的解锁位置后,用户将转移工具置于,例如可以存储在托盘中的悬架4上方。夹持臂46A和46B的远端穿过图2中所示悬架4的孔滑动。接着,用户旋转杠杆组件50到如图4A所示的锁定位置。当杠杆组件50旋转时,滑动凸轮48(图4C)从转移工具36的前面向转移工具36的后面滑动。这促使滑动凸轮48中的隆起物沿夹持臂46A和46B的轴承54A和54B滑动并且与之脱离,以便弹簧56朝向夹持臂46A和46B的基端彼此牵引所述基端,从而围绕枢轴旋转夹持臂46A和46B,以便如图4A所示夹持臂46A和46B的远端握紧悬架4。当滑动凸轮48进一步滑向转移工具36的后面时,其致动第一致动器38(图8A),以便使推进销40A和40B穿过悬架夹2(图2)的孔34A和34B伸出,从而压缩悬架夹2的弹簧10。当滑动凸轮48更进一步滑向转移工具36的后面时,第二致动器42(图7A)的轴承58跟随滑动凸轮48中的引导路径60,从而旋转第二致动器42的臂,该臂旋转驱动销44到图5A中所示的锁定位置。在这点上,如图4A所示,悬架夹2被锁定到转移工具36,允许用户将悬架4置于致动器臂6上。
为了将悬架4夹紧到致动器臂6,用户以相反方向旋转杠杆组件50到如图4B中所示的解锁位置。当用户开始旋转杠杆组件50时,由于轴承58跟随引导路径60(图7A),滑动凸轮48首先旋转第二致动器42的臂。随着该臂的旋转,其旋转驱动销44,从而将悬架夹的闭锁构件12旋转到如上所述的夹紧位置中。当滑动凸轮48进一步滑向转移工具36的前面时,第一致动器38如图5B中所示收缩推进销40A和40B,从而释放悬架夹2的弹簧10上的压缩力,并如上所述将悬架4夹紧到致动器臂6上。在图6和8A中所示的实施例中,第一致动器38包括由弹簧62偏置的活塞,当滑动凸轮48在轴承64上方滑动时弹簧62被压缩从而使推进销40A和40B伸出。当轴承64滑入滑动凸轮48(图8A)的引导路径60中时,弹簧62上的压缩力被释放,从而收缩推进销40A和40B。当滑动凸轮48进一步滑向转移工具36的前面时,滑动凸轮48中的隆起物如图4C中所示接触夹持臂46A和46B的轴承54A和54B,从而将夹持臂的远端从悬架4释放。接着,转移工具36可以在图4C中所示的状态中脱离悬架4。
图7B示出包括引导路径60中的凹口66的滑动凸轮的底部,其促使臂42在解锁操作结束时(夹紧操作结束时)少量旋转,以便将驱动销44从闭锁构件12的销24(图2)少量退回。通过这样的方式,在夹紧操作后当转移工具36从悬架4脱离时,其有助于减少否则由于驱动销44刮擦闭锁构件12的销24产生的污染物。图8B示出引导路径60的凹口66内的臂42的轴承58以及凹口66如何提供退回功能。
图9A示出包括盖子68的转移工具36的实施例,其中杠杆组件50处于锁定位置(悬架4锁定到转移工具36),以及图9B示出其中杠杆组件50处于解锁位置(悬架4被夹紧到致动器臂6并从转移工具36解锁)的转移工具36。
