图5是示出作为实施方式1的处理装置的换装装置的结构例的立体图。如图5所示,换装装置151具有:硬币式堆栈盒载置部43,其是载置硬币式堆栈盒20的收纳部21的盒载置部;读取单元41,其对载置于硬币式堆栈盒载置部43的硬币式堆栈盒20所具有的识别码28进行读取;盒载置部44,其载置处理用盒30;保护片收纳箱45,其对保护片6进行收纳;作为处理单元的搬送单元46;以及信息发布部42。
硬币式堆栈盒载置部43、盒载置部44以及保护片收纳箱45设置于换装装置151的装置主体47。在本实施方式中,装置主体47具有下层部48和上层部49而形成为阶梯状,硬币式堆栈盒载置部43和盒载置部44配置在上层部49上,保护片收纳箱45配置在下层部48上。另外,在实施方式1中,换装装置151在硬币式堆栈盒载置部43具有读取单元41。保护片收纳箱45形成为设置有供保护片6取出放入的上部开口部50的方形筒状。
搬送单元46将被加工物1或保护片6从载置于硬币式堆栈盒载置部43的硬币式堆栈盒20中搬出,将被加工物1收纳在载置于盒载置部44的处理用盒30中,将保护片6搬送至保护片收纳箱45。搬送单元46具有可动臂70、保持部80以及筛选单元90。
可动臂70设置于换装装置151的装置主体47的下层部48上。可动臂70具有:上下移动单元71,其设置于装置主体47的下层部48上;旋转单元72,其安装于上下移动单元71的上端;第1臂73,其以上下延伸的轴线为中心在水平方向上旋转自如地安装于旋转单元72的上端;以及第2臂74,其以上下延伸的轴线为中心在水平方向上旋转自如地安装于第1臂73的前端部。在第2臂74的前端部按照以上下延伸的轴线为中心旋转自如和以与水平方向平行的轴线为中心转动自如的方式安装有保持部80。
保持部80具有:保持部主体81,其形成为C字形平板状;以及多个(在本实施方式中为8个)吸附垫82,它们配设在保持部主体81,对被加工物1或保护片6喷出作为流体的空气而产生负压,从而以非接触状态对被加工物1或保护片6进行吸引。
保持部主体81例如由不锈钢板形成。保持部主体81具有对置的一对弧状部83、83,将该弧状部83、83彼此连结的基部与可动臂70的第2臂74的前端部连结。在弧状部83、83的各个弧状部上,在以穿过对置的弧状部83、83之间并且穿过基部的轴线为中心的对称的位置沿圆弧方向隔开间隔地配设有四个吸附垫82。
吸附垫82是所谓的伯努利垫:该吸附垫82喷出从未图示的流体提供源提供的加压后的空气,利用通过该喷出的空气而生成的伯努利效应所带来的负压,以非接触状态对被加工物1或保护片6进行吸附保持。吸附垫82设置于保持部80的保持部主体81的弧状部83、83的下表面上。
筛选单元(判别单元)90对被加工物1和保护片6进行筛选(判别)。筛选单元90具有振动检测单元91和控制单元92。
振动检测单元91对由于从吸附垫82喷出的空气而产生的被加工物1或保护片6的振动进行检测。振动检测单元91配置在保持部80的保持部主体81的基部。振动检测单元91由对被加工物1或保护片6的振动所引起的声音进行检测的麦克风构成。通过FFT(FastFourier Transform:快速傅立叶变换)分析仪对麦克风所检测到的声音的频率进行解析,并且控制单元92根据频带或声音的大小来筛选出搬送对象物是被加工物1还是保护片6。
控制单元92分别对构成换装装置151的上述结构要素进行控制而使换装装置151进行针对被加工物1或保护片6的搬送动作。另外,控制单元92是计算机,控制单元92具有:运算处理装置,其具有CPU(central processing unit:中央处理器)那样的微处理器;存储装置,其具有ROM(read only memory:只读存储器)或RAM(random access memory:随机存取存储器)那样的存储器;以及输入输出接口装置。控制单元92的运算处理装置按照存储于存储装置的计算机程序而实施运算处理,将用于控制换装装置151的控制信号经由输入输出接口装置而输出至换装装置151的上述结构要素。
控制单元92与由显示加工动作的状态或图像等的液晶显示装置等构成的显示单元51以及在操作者登记加工内容信息等时所用的输入单元连接。输入单元由设置于显示单元51的触摸面板和键盘等外部输入装置中的至少一个构成。
另外,控制单元92对搬送单元46所保持的搬送对象物是被加工物1还是保护片6进行筛选。具体而言,控制单元92根据麦克风所检测到的声音的大小和声音的频带来筛选出搬送对象物是被加工物1还是保护片6。例如,控制单元92在声音的大小超过规定值例如100db时,将搬送对象物筛选为保护片6,在声音的大小为规定值例如100db以下时,将搬送对象物筛选为被加工物1。
另外,控制单元92在将搬送对象物筛选为被加工物1时,使从吸附垫82喷出的空气的流量为第1流量,即能够对被加工物1进行保持的例如85L/min~110L/min,使从流体提供源提供的加压后的空气的压力为0.3MPa(表压),从硬币式堆栈盒20搬送至处理用盒30。另外,控制单元92在将搬送对象物筛选为保护片6时,使从吸附垫82喷出的空气的流量为比第1流量少的第2流量,即能够对保护片6进行保持且保护片6不因振动而产生异响(不产生共鸣)的例如40L/min~65L/min,使从流体提供源提供的加压后的空气的压力为0.15MPa(表压),从硬币式堆栈盒20搬送至保护片收纳箱45。这样,对搬送单元46的吸附垫82提供根据所吸引保持的搬送对象物的种类而预先设定的流量的流体(即加压后的空气)。
在上述结构的换装装置151中,在硬币式堆栈盒载置部43载置将盖22取下后的硬币式堆栈盒20。在换装装置151中,读取单元41读取载置于硬币式堆栈盒载置部43的硬币式堆栈盒20的识别码28。在换装装置151中,将从识别码28读取的信息和表示被加工物1已搬入至器件电路制造工厂12的信息一起由信息发布部42经由网络18而发送至订购方11。这样,信息发布部42将收纳于硬币式堆栈盒20的被加工物1已搬入至器件电路制造工厂12的情况通知给订购方11。
换装装置151利用筛选单元90对搬送单元46所保持的搬送对象物是被加工物1还是保护片6进行筛选,仅将被加工物1收纳于处理用盒30,并且将保护片6收纳于保护片收纳箱45。
除了在换装装置151的硬币式堆栈盒载置部43载置处理用盒30以外,换装装置161、171的结构与换装装置151相同,因此省略了说明。在换装装置161中,当搬入了收纳有被加工物1的处理用盒30时,读取单元41读取载置于硬币式堆栈盒载置部43的处理用盒30的识别码。在换装装置161中,将从识别码读取的信息和表示被加工物1已搬入至晶片磨削工厂13的信息一起由信息发布部42经由网络18而发送至订购方11。这样,信息发布部42将收纳于处理用盒30的被加工物1已搬入至晶片磨削工厂13的情况通知给订购方11。换装装置161将被加工物1从搬入的处理用盒30搬送至其他处理用盒30。
在换装装置171中,当搬入了收纳有被加工物1的处理用盒30时,读取单元41读取载置于硬币式堆栈盒载置部43的处理用盒30的识别码。在换装装置171中,将从识别码读取的信息和表示被加工物1已搬入至晶片分割工厂14的信息一起由信息发布部42经由网络18而发送至订购方11。这样,信息发布部42将收纳于处理用盒30的被加工物1已搬入至晶片分割工厂14的情况通知给订购方11。换装装置171将被加工物1从搬入的处理用盒30搬送至其他处理用盒30。
在实施方式1中,收纳于硬币式堆栈盒20的被加工物1已搬入至器件电路制造工厂12的情况、收纳于处理用盒30的被加工物1已搬入至晶片磨削工厂13的情况、以及收纳于处理用盒30的被加工物1已搬入至晶片分割工厂14的情况是器件芯片4的制造工序(被加工物1的处理工序)中的进展状况。
如上所述,在作为实施方式1的处理装置的换装装置151、161、171中,当搬入了硬币式堆栈盒20或处理用盒30时,读取单元41读取识别码28,信息发布部42通知器件芯片4的制造工序中的进展状况。即,通过作为实施方式1的处理装置的换装装置151、161、171,订购方11能够掌握器件芯片4的制造工序的进展状况。
在作为实施方式1的处理装置的换装装置151、161、171中,当硬币式堆栈盒20或处理用盒30载置于硬币式堆栈盒载置部43时,读取单元41读取识别码28,因此能够从工厂12、13、14自动地通知器件芯片4的制造工序中的进展状况。其结果是,通过作为实施方式1的处理装置的换装装置151、161、171,能够抑制工厂12、13、14的工时的增加。
另外,在实施方式1的器件芯片制造工厂10中,各工厂12、13、14的换装装置151、161、171通知器件芯片4的制造工序中的进展状况,因此订购方11能够掌握制造工序中的各工厂12、13、14之间的进展状况。
另外,作为处理装置的换装装置151的搬送单元46具有对被加工物1和保护片6进行筛选的筛选单元90,将硬币式堆栈盒20内的被加工物1收纳于处理用盒30内,将保护片6收纳于保护片收纳箱45内。因此,作为处理装置的换装装置151不通过作业者的手动作业便对硬币式堆栈盒20内的被加工物1和保护片6进行筛选,从而能够自动地收纳于处理用盒30和保护片收纳箱45。其结果是,换装装置151能够抑制将被加工物1从硬币式堆栈盒20收纳于处理用盒30的所需时间。
另外,当保持部80对保护片6进行吸引保持时,换装装置151使吸附垫82喷出的空气的流量比对被加工物1进行吸引保持的情况少。因此,换装装置151能够抑制搬送保护片6时的异响(共鸣声)。
另外,本发明并不限于上述实施方式。即,可以在不脱离本发明的主旨的范围内进行各种变形并实施。在上述的实施方式1中,换装装置151、161、171的读取单元41读取硬币式堆栈盒20的识别码28和处理用盒30的识别码,信息发布部42经由网络18将上述的信息发送至订购方11。但是,本发明也可以在除换装装置151、161、171以外的各种处理装置15、16、17中设置读取单元41和信息发布部42,这些各种处理装置15、16、17的读取单元41读取处理用盒30等的识别码,信息发布部42将工序的进展状况通知给订购方11。
