Description

硅棒研磨机及硅棒研磨方法 技术领域
本申请涉及硅工件加工技术领域,特别是涉及一种硅棒研磨机及硅棒研磨方法。

目前,随着社会对绿色可再生能源利用的重视和开放,光伏太阳能发电领域越来越得到重视和发展。光伏发电领域中,通常的晶体硅太阳能电池是在高质量硅片上制成的,这种硅片从提拉或浇铸的硅锭后通过多线锯切割及后续加工而成。
现有硅片的制作流程,以单晶硅产品为例,一般地,大致的作业工序可包括:先使用硅棒截断机对原初的长硅棒进行截断作业以形成多段短硅棒;截断完成后,使用硅棒开方机对截断后的短硅棒进行开方作业后形成单晶硅棒;再对各个硅棒进行磨面、倒角等加工作业,使得硅棒的表面整形达到相应的平整度及尺寸公差要求;后续再对硅棒进行切片作业以得到硅片。
一般情况下,在对硅棒进行磨面、倒角的工序中必须经由粗磨和精磨两个过程,对于待加工的某一单根硅棒而言,其要经过装载、转移至粗磨加工区位进行粗磨、转移至精磨加工区位进行精磨、最后卸载,再对另一硅棒进行装载、研磨(粗磨和精磨)及卸载,在通常的大批量加工中硅棒研磨机重复这一加工过程,硅棒研磨机的磨具有大量时间处于空闲状态,研磨效率低下,影响硅棒加工的经济效益。

具体实施方式
以下由特定的具体实施例说明本申请的实施方式,熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本申请的其他优点及功效。
在下述描述中,参考附图描述了本申请的若干实施例。应当理解,还可使用其他实施例, 并且可以在不背离本公开的精神和范围的情况下进行机械组成、结构以及操作上的改变。下面的详细描述不应该被认为是限制性的,并且本申请的实施例的范围仅由公布的专利的权利要求书所限定。这里使用的术语仅是为了描述特定实施例,而并非旨在限制本申请。空间相关的术语,例如“上”、“下”、“左”、“右”、“下面”、“下方”、“下部”、“上方”、“上部”等,可在文中使用以便于说明图中所示的一个元件或特征与另一元件或特征的关系。
虽然在一些实例中术语第一、第二等在本文中用来描述各种元件,但是这些元件不应当被这些术语限制。这些术语仅用来将一个元件与另一个元件进行区分。例如,第一硅棒夹具可以被称作第二硅棒夹具,并且类似地,第二硅棒夹具可以被称作第一硅棒夹具,而不脱离各种所描述的实施例的范围。第一硅棒夹具和第二硅棒夹具均是在描述某一个硅棒夹具,但是除非上下文以其他方式明确指出,否则它们不是同一个硅棒夹具。相似的情况还包括第一导向结构和第二导向结构、第一加工区位和第二加工区位、第一装载部件和第二装载部件、第一传动组件和第二传动组件等。
再者,如同在本文中所使用的,单数形式“一”、“一个”和“该”旨在也包括复数形式,除非上下文中有相反的指示。应当进一步理解,术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组,但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。此处使用的术语“或”和“和/或”被解释为包括性的,或意味着任一个或任何组合。因此,“A、B或C”或者“A、B和/或C”意味着“以下任一个:A;B;C;A和B;A和C;B和C;A、B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时,才会出现该定义的例外。
在对硅材料的加工中,通常需经由多道工序处理才可得到投入工业生产的硅片,原始的硅材料通常为长硅棒并呈圆柱形结构,由硅棒截断机对长硅棒截断后得到多段短硅棒;再由硅棒开方机对截断后的硅棒截段进行开方形成单晶硅棒,所得单晶硅棒截面呈类矩形(包括类正方形);开方所得的单晶硅棒需要去除表面损伤,并在棱角上进行倒角以消除内应力,继而需要对单晶硅棒进行磨面、倒角,使得硅棒的表面整形达到相应的平整度及尺寸公差要求后续方可进行最终的切片。
对单晶硅棒进行研磨的过程中,均需要先进行粗磨再进行精磨,分别由相应的粗磨磨具和精磨磨具来实现研磨,传统工作方式中是在粗磨工作区对单根单晶硅棒进行粗磨后将单晶硅棒转运至精磨工作区进行精磨,在精磨完成后将加工后的单晶硅棒运送出工作区,在大量的研磨工作中重复操作这一过程,精磨和粗磨的研磨顺序使得硅棒研磨机在作业中不可避免 的具有处于等待状态的磨具,例如,在粗磨磨具进行粗磨时精磨磨具处于等待状态,在精磨磨具进行精磨时粗磨磨具处于等待状态,研磨加工过程耗时较长。
在本申请提供的实施例中,为明确方向的定义与不同结构之间运作的方式,定义一个由第一方向、第二方向、第三方向定义的三维空间,所述第一方向、第二方向、第三方向均为直线方向且相互两两垂直。将硅棒加工设备的长度延伸方向也即硅棒放置于其上时的长度方向定义为第一方向(即前后方向或转移方向),将硅棒加工设备的宽度延伸方向也即左右方向定义为第二方向(即左右方向或进给方向),将竖直方向也即重垂线方向、垂向、上下方向或升降方向定义为第三方向。
在相关的针对硅棒的加工作业技术中,会涉及到例如开方切割、磨面、倒角等若干道工序。
一般地,现有的硅棒大多为圆柱形结构,通过硅棒开方设备对硅棒进行开方切割,使得硅棒在开方处理后截面呈类矩形(包括类正方形),而已加工的硅棒整体呈类长方体形(也可包括类立方体形)。以单晶硅棒为例,所述单晶硅棒是由原始硅棒经过硅棒截断并在之后经过硅棒开方装置进行开方所得,所述原始硅棒通常为通过用直拉法或悬浮区熔法从熔体中生长出棒状单晶硅。
以单晶硅棒为例,单晶硅棒的形成工艺可包括:先使用硅棒截断机对原始的长硅棒进行截断作业以形成多段短硅棒;截断完成后,又使用硅棒开方机对截断后的短硅棒进行开方作业形成截面呈类矩形的单晶硅棒。其中,使用硅棒截断机对原初的长硅棒进行截断作业以形成多段短硅棒的具体实现方式可参考例如为CN105856445A、CN105946127A、以及CN105196433A等专利公开文献,使用硅棒开方机对截断后的短硅棒进行开方作业后形成截面呈类矩形的单晶硅棒的具体实施方式则可参考CN105818285A等专利公开文献。但单晶硅棒的形成工艺并不见限于前述技术,在可选实例中,单晶硅棒的形成工艺还可包括:先使用全硅棒开方机对原初的长硅棒进行开方作业以形成截面呈类矩形的长单晶硅棒;开方完成后,又使用硅棒截断机对开方切割后的长单晶硅棒进行截断作业形成短晶硅棒。其中,上述中使用全硅棒开方机对原初的长硅棒进行开方作业以形成呈类矩形的长单晶硅棒的具体实现方式可参考例如为CN106003443A等专利公开文献。
在利用开方设备将圆柱形的单晶硅棒经开方切割形成类矩形的硅棒之后,可再利用研磨设备对类矩形的硅棒进行磨面、倒角等作业。
本申请的发明人发现,在相关的针对硅棒的研磨作业技术中,都是单根作业,只有当单 根硅棒依序完成例如粗磨作业和精磨作业之后,才能进行下一根硅棒的研磨作业,造成操作繁复且效率低下等问题。
有鉴于此,本申请公开一种硅棒研磨机及硅棒研磨方法,通过设备改造,在一个设备中集合了多个加工工位和多个加工装置,能自动化实现硅棒的研磨(例如磨面、倒角等),各个研磨作业之间无缝衔接,可提高硅棒研磨效率和缩短研磨作业耗时,及提升经济效率。

在某些实施例中,第一硅棒夹具2和第二硅棒夹具3的结构及其工作原理相同。在某些实施例中,第一硅棒夹具2和第二硅棒夹具3的结构或工作原理也可不相同。
在以下描述中,假设第一硅棒夹具2和第二硅棒夹具3的结构及其工作原理是相同的,现以第一硅棒夹具2为例进行说明。

在某些实现方式中,所述移动机构可包括:移动齿轨、驱动齿轮、以及驱动源。其中,所述移动齿轨沿第一方向设置,且其长度与所述第一转移导轨类似,可覆盖硅棒加工平台在第一方向上的完整长度。所述驱动齿轮设于所述夹臂安装座且与所述移动齿轨啮合。所述驱动源用于驱动所述驱动齿轮,所述驱动源可例如为驱动电机。在实际应用中,利用所述驱动源驱动所述驱动齿轮正向转动,通过驱动齿轮与所述移动齿轨的啮合,使得所述驱动齿轮及所述夹臂安装座沿着所述第一转移导轨作前向移动;反之,利用所述驱动源驱动所述驱动齿轮反向转动,通过驱动齿轮与所述移动齿轨的啮合,使得所述驱动齿轮及所述夹臂安装座沿着所述第一转移导轨作后向移动。
在某些实现方式中,所述移动机构可包括:移动丝杆和驱动源。其中,如图5所示,所述移动机构可包括移动丝杆221和驱动源223,所述移动丝杆221沿第一方向设置且与所述夹臂安装座21关联,且,所述移动丝杆221的长度与所述第一转移导轨类似,可覆盖硅棒加工平台在第一方向上的完整长度。所述驱动源223与所述移动丝杆221关联,用于驱动所述移动丝杆转动以使所关联的夹臂安装座沿第一方向移动,所述驱动源223可例如为伺服电机。在实际应用中,利用所述驱动源223驱动所述移动丝杆221正向转动,正向转动的所述移动丝杆221使得所述移动丝杆221上的所述夹臂安装座21沿着所述第一转移导轨前向移动;反之,利用所述驱动源223驱动所述移动丝杆221反向转动,反向转动的所述移动丝杆221使得所述移动丝杆221上的所述夹臂安装座21沿着所述第一转移导轨后向移动。

在某些实施例中,所述夹臂驱动机构可驱动所述一对夹臂中的第一个夹臂沿着第一方向朝向第二个夹臂靠近,减小两个夹臂之间的夹持间距,从而将位于所述两个夹臂之间的硅棒夹紧。相应地,所述夹臂驱动机构可驱动所述一对夹臂中的第一个夹臂沿着第一方向背向第二个夹臂远离,增大两个夹臂之间的夹持间距,以释放夹持的硅棒。
假定所述一对夹臂中的第一个夹臂可由夹臂驱动机构驱动沿着第一方向移动,所述一对夹臂中的第二个夹臂则固定设置于夹臂安装座上,在一种实施方式中,所述夹臂驱动机构更可包括:丝杆和驱动源,其中,所述丝杆沿第一方向设置且与所述一对夹臂中的第一个夹臂关联,所述驱动源与所述丝杆关联,用于驱动所述丝杆转动以使所关联的第一个夹臂沿第一方向移动。例如,所述驱动源驱动所述丝杆正向转动,则驱动所关联的第一个夹臂沿着第一方向朝向第二个夹臂靠近,减小两个夹臂之间的夹持间距,或者,所述驱动源驱动所述丝杆反向转动,则驱动所关联的第一个夹臂沿着第一方向背向第二个夹臂远离,增大两个夹臂之间的夹持间距。其中,所述驱动源可例如为伺服电机。当然,所述夹臂驱动机构仍可采用其他结构,例如,在其他某一实施方式中,所述夹臂驱动机构可包括:齿条、驱动齿轮、以及驱动电机,其中,所述齿条沿第一方向设置且与所述一对夹臂中的第一个夹臂关联,所述驱动齿轮受控于所述驱动电机且与所述齿条啮合,如此,所述驱动电机带动驱动齿轮旋转,带动所述齿条及其关联的第一个夹臂沿第一方向移动。例如,所述驱动源驱动所述驱动齿轮正向转动,则驱动所述齿条所关联的第一个夹臂沿着第一方向朝向第二个夹臂靠近,减小两个夹臂之间的夹持间距,或者,所述驱动源驱动所述驱动齿轮反向转动,则驱动所述齿条所关联的第一个夹臂沿着第一方向背向第二个夹臂远离,增大两个夹臂之间的夹持间距。

首先,将待上料的第一硅棒至于硅棒移送装置上。在图式所示的状态中,可采用人工方式或借助相应的机械装置将第一硅棒至于硅棒移送装置7的第一装载部件和第二装载部件上。
接着,利用硅棒移送装置将待上料的第一硅棒移动至第一加工区位。在图式所示的状态中,利用硅棒移送装置将待上料的第一硅棒移动至第一加工区位的具体步骤可包括:利用第一居中调节机构,驱动第一装载部件和第二装载部件沿着第二方向相向移动,使得第一硅棒的轴心线与第一硅棒上料承载结构中沿第二方向上的中心线对齐;利用进给驱动机构驱动硅棒上料承载结构及其所承载的第一硅棒沿着第二方向移动至第二居中调节机构处;利用第二居中调节机构,调节第一硅棒在第一方向上的位置,使得第一硅棒位于硅棒上料承载结构在第一方向上的居中区域,另外,利用高度检测仪对第一硅棒进行多点检测,得到第一硅棒的轴心线在重垂线方向上的位置信息;利用进给驱动机构驱动硅棒上料承载结构及其所承载的第一硅棒沿着第二方向移动以回退至初始位置处;根据第一硅棒的轴心线在重垂线方向上的位置信息和所要移动的第一加工区位处第一硅棒夹具2的夹持中心线在重垂线方向上的位置信息,确定两者的差值,利用垂向升降机构驱动硅棒上料承载结构及其所承载的第一硅棒沿重垂线方向执行升降动作,使得第一硅棒的轴心线第一加工区位处第一硅棒夹具2的夹持中心线在重垂线方向上对齐;利用进给驱动机构驱动硅棒上料承载结构及其所承载的第一硅棒沿着第二方向移动至第一加工区位上,以令第一加工区位处第一硅棒夹具2夹持第一硅棒。
接着,令设于第一加工区位的第一硅棒夹具夹持装载的第一硅棒并带动所夹持的第一硅棒沿第一方向移动,令位于第一加工区位的粗磨装置对第一硅棒进行粗磨作业。在图式所示的状态中,第一硅棒夹具2夹持住装载的第一硅棒的相对两端,使得第一硅棒的轴心线平行于第一方向,之后,第一硅棒夹具2带动所夹持的第一硅棒沿着第一方向移动,令位于第一加工区位的粗磨装置4对沿着第一方向移动的第一硅棒进行粗磨作业。在本实施例中,粗磨装置4中包括至少一对粗磨磨具,所述至少一对粗磨磨具沿重垂线方向设置,所述至少一对粗磨磨具的研磨面位于相对的水平面内。
在对第一硅棒进行粗磨作业的过程中,所述相对设置的一对粗磨磨具在重垂线方向移动, 以确定粗磨磨具与硅棒研磨面研磨的进给量,用于对第一硅棒沿重垂线方向的上侧面和下侧面进行研磨,此时,由第一硅棒夹具2带动所夹持的第一硅棒沿着第一方向移动,使得一对粗磨磨具中两个粗磨磨具的研磨面沿着第一方向从第一硅棒的前端开始研磨直至到达第一硅棒的后端,即,完成对第一硅棒相对的上侧面和下侧面的研磨;或者,所述第一硅棒夹具2带动所夹持的第一硅棒在第一方向上迂回移动,使得所述第一硅棒与粗磨装置4中的至少一对粗磨磨具的研磨面在研磨中充分覆盖第一硅棒的。

在利用第一硅棒夹具2带动所夹持的第一硅棒沿着第一方向移动直至使得第一硅棒完成穿过粗磨装置4,使得粗磨装置4中至少一对粗磨磨具对第一硅棒的上侧面和下侧面进行粗磨作业;之后驱动第一硅棒夹具2中的夹持部转动预设角度(例如,90°),带动第一硅棒夹具2所夹持的第一硅棒转动预设角度(例如,90°)使得第一硅棒中原先的左侧面和右侧面通过转动变换为上侧面和下侧面(或,下侧面和上侧面),如此,即可通过粗磨装置4中的至少一对粗磨磨具继续对第一硅棒中变换后新的上侧面和下侧面进行粗磨作业,从而完成第一硅棒中各个侧面的粗磨作业。
其中,所述利用粗磨装置4对第一硅棒中变换后新的上侧面和下侧面进行粗磨作业,可采用多种实现方式。例如,在第一硅棒夹具2带动所夹持的第一硅棒由第一加工区位的第一侧沿着第一方向移动至第一加工区位的第二侧以使得粗磨装置4中的至少一对粗磨磨具对第一硅棒的第一对侧面进行粗磨作业之后,此时,第一硅棒夹具2及其所夹持的第一硅棒已移动至第一加工区位的第二侧。在一种实现方式中,控制相对设置的一对粗磨磨具在重垂线方向移动以确定粗磨磨具与第一硅棒研磨面研磨的进给量,同时,驱动第一硅棒夹具2中的夹持部转动预设角度(例如,90°),带动第一硅棒夹具2所夹持的第一硅棒转动预设角度(例如,90°)使得第一硅棒中原先的左侧面和右侧面通过转动变换为上侧面和下侧面(或,下侧面和上侧面),随后,驱动第一硅棒夹具2,由第一硅棒夹具2带动所夹持的第一硅棒由第一加工区位的第二侧沿着第一方向移动至第一加工区位的第一侧以使得粗磨装置4中的至少一对粗磨磨具对第一硅棒中转动后新的第二对侧面进行粗磨作业。在另一种实现方式中,控制相对设置的一对粗磨磨具在重垂线方向移动(例如回到初始位置)以增大一对粗磨磨具之间的间距;驱动第一硅棒夹具2带动所夹持的第一硅棒由第一加工区位的第二侧沿着第一方向移动至第一加工区位的第一侧;驱动第一硅棒夹具2中的夹持部转动预设角度(例如,90°), 带动第一硅棒夹具2所夹持的第一硅棒转动预设角度(例如,90°)使得第一硅棒中原先的左侧面和右侧面通过转动变换为上侧面和下侧面(或,下侧面和上侧面);控制相对设置的一对粗磨磨具在重垂线方向移动以确定粗磨磨具与第一硅棒研磨面研磨的进给量,同时,驱动第一硅棒夹具2带动所夹持的第一硅棒由第一加工区位的第一侧沿着第一方向移动至第一加工区位的第二侧以使得粗磨装置4中的至少一对粗磨磨具对第一硅棒中转动后新的第二对侧面进行粗磨作业。
在本申请的实施例中,当粗磨装置4中的至少一对粗磨磨具对第一硅棒中的各个侧面均执行完粗磨作业之后,驱动第一硅棒夹具2带动所夹持的第一硅棒由第一加工区位的第二侧沿着第一方向移动至第一加工区位的第一侧。
在此阶段,将第二硅棒置于硅棒移送装置,并利用硅棒移送装置将待上料的第一硅棒移动至第二加工区位。
利用硅棒移送装置将待上料的第一硅棒移动至第一加工区位的具体步骤可包括:利用第一居中调节机构,驱动第一装载部件和第二装载部件沿着第二方向相向移动,使得第二硅棒的轴心线与第一硅棒上料承载结构中沿第二方向上的中心线对齐;利用进给驱动机构驱动硅棒上料承载结构及其所承载的第二硅棒沿着第二方向移动至第二居中调节机构处;利用第二居中调节机构,调节第二硅棒在第一方向上的位置,使得第二硅棒位于硅棒上料承载结构在第一方向上的居中区域,另外,利用高度检测仪对第二硅棒进行多点检测,得到第二硅棒的轴心线在重垂线方向上的位置信息;利用进给驱动机构驱动硅棒上料承载结构及其所承载的第二硅棒沿着第二方向移动以回退至初始位置处;根据第二硅棒的轴心线在重垂线方向上的位置信息和所要移动的第二加工区位处第二硅棒夹具的夹持中心线在重垂线方向上的位置信息,确定两者的差值,利用垂向升降机构驱动硅棒上料承载结构及其所承载的第二硅棒沿重垂线方向执行升降动作,使得第二硅棒的轴心线第二加工区位处第二硅棒夹具3的夹持中心线在重垂线方向上对齐;利用进给驱动机构驱动硅棒上料承载结构及其所承载的第二硅棒沿着第二方向移动至第二加工区位上,以令第二加工区位处第二硅棒夹具3夹持第二硅棒。
接着,令换位机构驱动粗磨装置和精磨装置转换位置使得粗磨装置由第一加工区位转换至第二加工区位以及精磨装置由第二加工区位转换至第一加工区位。在图式所示的状态中,驱动换位转轴转动预设角度,可使得粗磨装置4和精磨装置5在第一加工区位和第二加工区位之间转换位置,即,粗磨装置4由原先的第一加工区位换位至第二加工区位且精磨装置5由原先的第二加工区位换位至第一加工区位。在某些实施例中,换位转轴设于重垂线方向,所述第一加工区位与第二加工区位设于换位转轴沿第二方向的相对两侧,粗磨装置4和精磨 装置5分别设置于换位转轴相对两侧,例如,粗磨装置4和精磨装置5以背靠背的方式设置于换位转轴的相对两侧,即,粗磨装置4和精磨装置5可相差180°,如此,驱动换位转轴转动预设角度180°之后,可使得粗磨装置4和精磨装置5在第一加工区位和第二加工区位之间转换位置。
