参见图1和图2,本申请中,安装座1上开设有多个第一检测通道111和多个第二检测通道112,多个第一检测通道111和多个第二检测通道112均沿安装座1的长度方向(即图1示出的待切割件4的轴线方向)排列。具体地,本申请中设置有两个第一检测通道111和两个第二检测通道112,两个第一检测通道111和两个第二检测通道112沿安装座1的长度方向排列,且设置于安装座1靠近两端的位置。其中,对应设置的第一检测通道111与第二检测通道112之间均通过过渡通道113连通。通过开设多个第一检测通道111和第二检测通道112,可以对晶托3不同位置的第一夹紧面和第二夹紧面的夹紧程度进行检测,提高检测精度。
需要说明的是,上述优选的实施方式仅仅用于阐述本申请的原理,并非旨在于限制本申请的保护范围。在不偏离本申请原理的前提下,本领域技术人员可以对上述设置方式进行调整,以便本申请能够适用于更加具体的应用场景。例如,在一种可替换的实施方式中,虽然上述优选实施方式是结合安装座1上同时设置两个第一检测通道111和两个第二检测通道112进行介绍的,但是这并非旨在于限制本申请的保护范围,在能够实现对晶托3夹紧程度检测的前提下,本领域技术人员可以对检测通道的设置数量、位置等进行调整。举例而言,安装座1上可以只设置第一检测通道111来检测晶托3顶部的夹紧程度,省略第二检测通道112的设置。再如,第一检测通道111也可以为检测晶托3侧面夹紧程度的通道,相应地第二检测通道112为检测晶托3顶面夹紧程度的通道。再如,在同时设置第一检测通道111和第二检测通道112的前提下,第一检测通道111的数量和第二检测通道112的数量本领域技术人员可以调整,只要满足二者各至少有一个即可,当然二者的设置数量可以相同,也可以不同。

下面参照图22至图31,对辊轴组件进行说明。如图22所示,现有的辊轴组件包括辊轴1、拉杆2、第一轴承箱3和第二轴承箱4,辊轴1一端与第一轴承箱3的第一旋转轴31传动连接,另一端与第二轴承箱4的第二旋转轴41传动连接。第一旋转轴31远离辊轴1的一端伸出第一轴承箱3,与电机8通过联轴器7连接。辊轴1上开设有第一孔道121,第一孔道121内插设有拉杆2,第一旋转轴31靠近辊轴1的一端开设有第一轴孔32,拉杆2一端螺接于第一轴孔32内。第二旋转轴41开设有第二轴孔,拉杆2远离第一轴承 箱3的一端依次伸出第一孔道121、第二轴孔,伸出第二轴孔的拉杆2通过螺母561轴向锁紧。这样的结构设置,使得线切割机在工作过程中,电机8通过联轴器7驱动第一旋转轴31高速转动,由于第一旋转轴31与辊轴1传动连接,辊轴1与第二旋转轴41传动连接,因此辊轴1以及第二旋转轴41同步转动,从而带动缠绕在辊轴1上的金刚线6高速转动,实现对待切割材料的切割。但是由于辊轴组件不具备冷却的功能,线切割机在切割过程中,辊轴1温度逐渐增加,使得辊轴1的热变形随之加大,而辊轴1的热变形增加则会导致线切割机的切割精度下降,切割材料的质量降低,甚至还会导致辊轴1上缠绕的金刚线6出现断线的问题。
如图23-图25所示,本申请的辊轴组件包括辊轴1和拉杆2,辊轴1上设置有第一孔道121和第二孔道13;拉杆2至少部分插设在第一孔道121内,拉杆2内设置有第一通道21,拉杆2上分别设置有与第一通道21连通的进液口22和出液口23;进液口22与切割液供给装置的出口连通,出液口23与第二孔道13的第一端连通,第二孔道13的第二端与切割液供给装置的进口连通。通过在辊轴1上的第一孔道121内插设拉杆2,拉杆2内设置第一通道21及与第一通道21连通的进液口22和出液口23,使得切割液供给装置中的切割液能够通过进液口22流入到第一通道21内,再通过出液口23流入到第二孔道13,第二孔道13内的切割液再回流到切割液供给装置中,以此循环能够对辊轴1冷却,降低切割过程中辊轴1的温度,从而降低辊轴1在高速切割时产生的热变形,提高线切割机的切割精度以及切割材料的切割质量,还能够避免金刚线6出现断线的问题。

下面参照图40和图41,对本申请的线切割机进行介绍。线切割机包括底座3、切割总成4、液路总成5、绕线区总成6、电控柜7以及上述的供液组件。切割总成4、液路总成5和绕线区总成6固定安装在底座3上,电控柜7安装在绕线区总成6的顶部上侧。安装好后,液路总成5的一部分由底座3沿其长度方向的第二端(图40的左上端)伸出,使得液路总成5伸出底座3第二端的部分与整机安装面之间形成容纳空间,供液缸1部分位于该容纳空间内。具体地,切割总成4包括切割区框架41以及固定在切割区框架41上的进给组件(未示出)、主辊组件(未示出)、切割液回流组件42等。切割区框架41通过螺接的方式固定连接在底座3的顶面沿其长度方向的第一端(图40中的右下端),并且切割区框架41的整体宽度与底座3宽度大致相等。主辊组件安装在切割区框架41内部,用于缠绕金刚线。切割液回流组件42安装在切割区框架41的底部,用于对切割液进行回收。其中,切割液回流组件42大致成漏斗结构,漏斗中部形成有切割液回流口,切割液回流口通过管路与切回液缸2的第二进液口211连通。液路总成5包括液路框架51以及固定在液路框架51上的液路组件(未图示),液路框架51螺接固定在底座3顶面沿其长度方向的第二端(图37中的左上端),并且液路框架51的整体宽度与底座3宽度大致相等。液路组件包括切割液进液口,液路组件主要用于对通过该切割液进液口进入液路组件切割液进行温控和过滤,然后将处理好的切割液输送给切割总成4,用以对棒料和金刚线进行润滑冷却。绕线区总成6固定安装在底座3顶面且位于切割总成4与液路总成5之间,用于向主辊组件提供金刚线,并提供线网切割必须的切割张力。电控柜7固定安装在绕线区总成6的顶部上侧。本申请中,电控柜7设置有两个,两个电控柜7并排布置。
线切割机工作时,回液缸2接收切割液回流组件42回收的切割液,根据第二液位组件23的反馈信号,在第二缸体21内的液位达到预设液位时,回液泵22运行将切割液输送至供液缸1内。供液缸1内的加热部12对切割液进行加热,温度传感器13检测切割液温度,当达到预定温度后,加热部12停止加热。搅拌组件15将切割液搅拌均匀后,供液泵14将切割液输送至液路组件,经液路组件对切割液温控和过滤后,将切割液输送至切割总成4,用以对棒料和金刚线进行润滑冷却,其中加热后的切割液对棒料冷却时,减小棒料内外温差。冷却后的切割液继续通过切割液回流组件42回收至回液缸2,实现切割液循环流动。
本申请还提供了一种线切割机,线切割机包括上述实施方式的进给机构、切割液***、切割总成。
参见图42,对应于上述晶托夹紧装置,本申请还提供了一种晶托夹紧检测方法,晶托夹紧检测方法包括:S101、获取第一检测通道的实时气压值。举例而言,打开气源对第一检测通道通气,在通气一定时间后,通过压力检测部来检测第一检测通道内的实时气压值。S103、判断实时气压值与预设气压阈值的大小。举例而言,预设气压阈值为提前设置的,其可以通过试验、理论计算或者经验值确定,该预设气压阈值代表晶托夹紧程度满足加工要求的临界值。在获取到实时气压值后,将实时气压值与预设气压阈值进行比较。 S105、根据判断结果,确定晶托的夹紧状态。举例而言,在实时气压值大于等于预设气压阈值时,确定晶托处于夹紧状态;否则,在实时气压值小于预设气压阈值时,确定晶托处于未夹紧状态。通过获取实时气压值,并判断实时气压值与预设气压阈值的大小,本申请的晶托夹紧检测方法可以对晶托是否夹紧进行有效检测,使得后续工序的顺利实施,提高线切割机的切割精度和切割质量。
在上述晶托夹紧检测方法的优选技术方案中,根据判断结果,确定晶托的夹紧状态进一步包括:如果实时气压值大于等于预设气压阈值,则确定晶托处于夹紧状态;如果实时气压值小于预设气压阈值,则确定晶托处于未夹紧状态。具体地,如果实时气压值大于等于预设气压阈值,则证明第一检测通道和第二检测通道没有气体泄漏,或只有微小泄漏,此时认为晶托的顶面和侧面均已夹紧。反之,如果实时气压值小于预设气压阈值,则证明第一检测通道和第二检测通道至少存在一处气体泄漏,此时认为晶托的顶面和侧面至少有一处没有夹紧。
在上述晶托夹紧检测方法的优选技术方案中,晶托夹紧检测方法还包括:在晶托处于未夹紧状态时,发出报警信息;在晶托处于夹紧状态时,发出已夹紧信息或不执行任何操作。举例而言,在实时气压值小于预设气压阈值时,晶托处于未夹紧状态,此时如果继续进行后续的工序,则容易影响切割精度和切割质量,因此需要及时发出报警信息来提示工作人员晶托处于未夹紧状态。本申请中,报警信息可以为声/光信息、也可以为文字信息。例如,控制设备发出警报音、同时控制报警灯闪烁、同时控制操作屏幕弹窗文字信息等。反之,在实时气压值大于等于预设气压阈值时,晶托处于夹紧状态,此时可以继续后续工序的操作,可以提示工作人员晶托已经加紧,也可以不发出任何提示,实现无感检测。在需要提示工作人员时,可以发出声/光信息、也可以发出文字信息。例如,控制设备发出“晶托已夹紧”的语音信息、控制设备上的绿灯亮起、控制操作屏幕弹窗显示晶托已夹紧文字等。通过在晶托处于未夹紧状态时发出报警信息,可以及时提示工作人员对晶托夹紧程度进行调整,使得后续工序顺利实施。
需要说明的是,上述实施例中虽然将各个步骤按照上述先后次序的方式进行了描述,但是本领域技术人员可以理解,为了实现本实施例的效果,不同的步骤之间不必按照这样的次序执行,其可以同时(并行)执行或以颠倒的次序执行,这些简单的变化都在本申请的保护范围之内。
此外,本领域的技术人员能够理解,尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征,但是不同实施例的特征的组合意味着处于本申请的范围之内并且形成不同的实施例。例如,在本申请的权利要求书中,所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
至此,已经结合附图所示的优选实施方式描述了本申请的技术方案,但是,本领域技术人员容易理解的是,本申请的保护范围显然不局限于这些具体实施方式。在不偏离本申请的原理的前提下,本领域技术人员可以对相关技术特征作出等同的更改或替换,这些更改或替换之后的技术方案都将落入本申请的保护范围之内。
