前記クリーニング部は、前記セット位置と前記加工位置との間の領域に設けられている、技術1から技術5のいずれか1つに記載の切断装置。
この切断装置においては、セット位置と加工位置との間の領域にクリーニング部が設けられている。したがって、この切断装置によれば、ドレッシング用テーブルによって保持されたドレスボードをクリーニング部で洗浄することができる。その結果、この切断装置によれば、例えば、切断対象物の切断加工を通じて生じた加工屑がドレスボードに付着した場合であっても、ドレスボードを洗浄することができ、洗浄後のドレスボードを用いてブレードのドレッシングを行なうことができる。
(構成)
前記クリーニング部は、少なくとも液体を用いることによって前記切断対象物及び前記ドレスボードの各々を洗浄するように構成されている、技術6に記載の切断装置。
この切断装置によれば、ドレッシング用テーブルによって保持されたドレスボードを少なくとも液体を用いて洗浄することができる。
(構成)
前記基板搬送部は、下方に延びるピンを含み、
前記切断用テーブルには孔が形成されており、
前記基板搬送部は、前記ピンが前記孔に進入した状態で、前記切断対象物を前記切断用テーブルに保持させるように構成されており、
前記ドレスボード搬送部は、平面視において前記基板搬送部と前記切断用テーブルとが重ならない状態で、前記ドレッシング用テーブルとの間で前記ドレスボードの授受を行なうように構成されている、技術1から技術7のいずれか1つに記載の切断装置。
この切断装置においては、切断対象物の位置精度を確保するために、基板搬送部のピンが切断用テーブルの孔に進入した状態で、切断対象物が切断用テーブル上に配置される。仮に、平面視において基板搬送部と切断用テーブルとが重なった状態でドレスボード搬送部とドレッシング用テーブルとの間でドレスボードの授受が行なわれると、基板搬送部のピンが邪魔になる可能性がある。この切断装置によれば、平面視において基板搬送部と切断用テーブルとが重ならない状態でドレスボード搬送部とドレッシング用テーブルとの間でドレスボードの授受が行なわれるため、ドレスボードの授受を適切に行なうことができる。
(構成)
技術1から技術8のいずれか1つに記載の切断装置を用いた切断品の製造方法であって、
前記切断対象物を吸着すると共に、吸着された前記切断対象物を前記切断用テーブルへ搬送するステップと、
前記収容機構及び前記ドレッシング用テーブル間において、前記ドレスボードを搬送するステップと、
前記ドレッシング用テーブルに保持された前記ドレスボードを用いて前記ブレードのドレッシングを行なうステップと、
前記ドレッシングが行なわれた前記ブレードを用いて前記切断用テーブルに保持された前記切断対象物を切断し、前記切断品を製造するステップとを含む、切断品の製造方法。
この切断品の製造方法においては、収容機構及びドレッシング用テーブル間において、ドレスボードが自動搬送される。したがって、この切断品の製造方法によれば、ドレスボードが収容機構及びドレッシング用テーブル間で自動搬送されるため、ドレッシング用テーブルに取り付けられるドレスボードを自動的に交換することができる。
