Description

粉末回收後處理系統
本案係關於一種3DRP快速成型後處理裝置，尤指一種粉末回收後處理系統。
快速成型技術(Rapid Prototyping，簡稱RP技術)係為依據建構金字塔層層堆疊成型的概念所衍生的技術，其可以快速且低成本的將設計者的構想在短時間內成型，呈現給社會大眾，其主要特徵是成型的快捷性，能在不需要任何刀具、模具以及冶具的情況下，自動、快速地將任意複雜形狀的設計方案快速轉換為3D的實體模型，大大縮短了新產品的研發週期及減少研發成本，並能夠確保新產品的上市時間和新產品一次開發的成功率，它促使技術人員之間，以及技術人員與企業決策者、產品的用戶等非技術人員之間提供一個更加完整及方便的產品設計交流工具，從而明顯地提高產品在市場上的競爭力及企業對市場的快速反應能力。
目前RP技術發展出利用噴印技術結合載具精密定位技術的方式來生產3D的實體模型，其生產方式係為先將一層建構粉末鋪設於載具上方並利用噴墨列印技術於部分建構粉末上噴印高黏度膠合劑液體，使膠合劑液體與建構粉末沾黏並固化，一直重複上述製程層層堆砌即可完成3D的實體模型。
習用RP技術之立體成型機構在鋪粉、列印及取出成型品時，係以人工方式進行，且所揚起的粉塵常會造成工作環境的汙染，且容易沾染於立體成型裝置的整個作業機台上，為了維持作業正常，習用技術需於進行某一階段作業後，就要以人工方式執行吸塵及清掃保養的工作。如此一來，習用RP技術之清潔過程中，易因人工操作而不慎損毀成型品、破壞立體成型裝置之構件；以及，高頻率的清潔亦會造成人力及時間的浪費，相對地提高了整體製作成本，而若減少清潔頻率，又有粉塵汙染而不易維持作業空間清潔之虞。
有鑒於此，如何發展一種適用於立體成型機構之粉末自動回收系統，以改善上述習用技術缺失，實為目前迫切需要解決之問題。
本案之目的在於提供一種粉末回收後處理系統，俾解決習知立體成型機構的設計在鋪粉、列印及取出成型品時，所揚起的粉塵會造成工作環境的汙染等缺點，解決工作環境不受粉末之空氣污染，物件放入系統之密封腔室內的可進行粉末回收後處理，而在密封腔室內安裝過濾網，並連接負壓裝置，促使密封腔室內清除粉末時可保持在一負壓空間粉末不易飄散，達到空間較佳的潔淨度，而密封腔室內被清除的粉末也可直接掉入一粉末收集盒中回收利用，也可以在密封腔室內進行人工操作配合噴槍加強3D成型物清除粉末更潔淨之粉末回收處理。
為達上述目的，本案之一較廣義實施態樣為提供一種粉末回收後處理系統，主要包括：密封主體，具有由複數個隔板區隔出一密封腔室及一裝置置放空間及一餘料置放空間相互隔離，該密封腔室具有複數個開口之一前門板，每一該開口分別設置一隔絕構件相連接，以及該密封腔室底部設置有一篩網，而該餘料置放空間內設有一粉末收集盒，供 以對應該篩網下方集中收集餘料粉末回收利用；一負壓裝置，設置於該密封主體之該裝置置放空間內，提供一負壓氣流；一空壓產生裝置，具有一管路連接到該密封腔室並連接一噴槍，提供一吹氣氣流至該噴槍，以對該立體成型物作人工吹氣操作餘料粉末回收後處理；一照明燈具，提供該密封腔室間內照明；以及一加熱燈具，提供熱源以對該密封腔室間內3D成型物加強成型物化學鏈結反應時間。

體現本案特徵與優點的一些典型實施例將在後段的說明中詳細敘述。應理解的是本案能夠在不同的態樣上具有各種的變化，其皆不脫離本案的範圍，且其中的說明及圖示在本質上係當作說明之用，而非架構於限制本案。
如第1圖至第4圖所示，本發明粉末回收後處理系統，主要包括一密封主體1、一負壓裝置2、一空壓產生裝置3、一照明燈具4以及一加熱燈具5。
密封主體1內具有由複數個隔板11區隔出密封腔室12、裝置置放空間13及餘料置放空間14相互隔離，其中，複數個隔板11中更包含第一隔板11a，第一隔板11a係設置於密封腔室12與裝置置放空間13之間，該密封腔室12可供3D成型物6容置其中進行餘料粉末清除作業，該密封腔室 12具有一前門板121，可開啟以供3D成型物6置入，且前門板121設有一可透視之視窗122，以及具有複數個開口123，每一開口123分別設置一個隔絕構件124相連接，使得密封腔室12內部與外界環境隔絕以形成一密封空間。本實施例之隔絕構件124為一工作手套，供操作者可進行人手操作餘料粉末清除作業，操作人員將雙手伸入該密封腔室12中手動清除粉末，完全無造成進氣空隙之空間，可達成全密閉除粉作業，也不造成空氣粉末污染之作業環境。
又該密封腔室12底部進一步設置有一篩網125，而該餘料置放空間14內設有一粉末收集盒141，該粉末收集盒141設置於該篩網125下方，促使於密封腔室12內進行餘料粉末清除作業之3D成型物6所清除餘料粉末能由篩網125落入而集中收集於粉末收集盒141中再回收利用。
負壓裝置2及空壓產生裝置3皆設置於密封主體1內由隔板11隔離密封腔室12之裝置置放空間13內，負壓裝置2提供負壓吸附氣流，空壓產生裝置3提供一吹氣氣流。本實施例之負壓裝置2為一吸氣泵浦，空壓產生裝置3為一空壓機。
如第2圖及第4圖所示，該負壓裝置2設有一吸入通道21及一出氣通道22，該吸入通道21之一端部架置於該隔板11上而連通該密封腔室12，且該吸入通道21之該端部設置有一過濾網221，以對該密封腔室12進行負壓吸入氣流時，將吸入氣流內懸浮粉粒或塵埃予以過濾，以使該密封腔室12進行導入負壓吸附粉塵之餘料粉末清除作業。
該空壓產生裝置3具有一管路31連接到該密封腔室12並可連接一設置於該密封腔室12內的噴槍32，供以導接該空壓產生裝置3所輸送之氣流，促使該噴槍32強力噴出空壓氣流，以使操作者套入該工作手套拿 取噴槍32進行承載於篩網125之3D成型物6，進行人工操作吹氣之餘料粉末清除作業。
該照明燈具4及該加熱燈具5皆設置於該密封腔室間12內，該照明燈具4提供該密封腔室12內照明，該加熱燈具5可針對在該密封腔室12內進行餘料粉末清除作業之3D成型物6提供熱源，加強3D成型物6內化學鏈結反應時間，以成型後有良好機械強度。
綜上所述，本發明提供一種粉末回收後處理系統，解決工作環境不受粉末之空氣污染，物件放入粉末回收後處理系統之密封腔室內可進行粉末回收後處理，而在密封腔室內安裝過濾網，並連接負壓裝置，促使密封腔室內清除粉末時可保持在一負壓空間粉末不易飄散，達到空間較佳的潔淨度，而密封腔室內被清除的粉末也可直接掉入一粉末收集盒中回收利用，也可以在密封腔室內進行人工操作配合噴槍加強3D成型物清除粉末更潔淨之粉末回收處理。
