模具之零件知識庫的自動化組裝

隨著科技的快速發展與現今產品的多樣化，使用者對產品的機構和外觀有了更高的要求，也因此模具零件的選用上不僅多樣化，還會因產品特殊需求而更改標準零件之尺寸，導致眾多零件缺乏管理，而在零件組裝方面，因模板與零件間干涉問題，需對干涉模板做出逃孔設計，對於設計工程師是一件費時的工程。因此本研究在CAD軟體下，導入引導流程，以標準化流程引導使用者完成設計，接著利用Microsoft 的.NET Framework與資料庫(Structured Query Language, SQL)的結合，開發網頁版標準零件庫，經由資料庫的參數變動，進而達到客製化目的，其中在零件的建構部分，Pro/ENIGNEER內含三種形式，包括一般型、程式型與族表型(Family Table)，本研究主要利用族表型來建立零件樣本，其應用在尺寸選擇眾多且有規則的零件上，而零件上會建立組裝特徵和切割曲面，此曲面特徵會以參數化的方式與零件尺寸對應，將族表內的尺寸以資料表的形式紀錄，而這些資料則透過資料庫來負責維護，兩者間透過Pro/Web.Link進行控制，以達到與零件溝通的目的。根據以上幾點，不僅能有效管理零件，還可配合不同需求製作客製化零件庫，最後利用建立在零件上的特徵和曲面進行自動化組裝和切割，如此一來，可以確保模具設計的一致性，並且可減少設計者投入在繪製與組裝零件上的設計工時；透過本研究之模具零件知識庫，以及自動化組裝的幫助下，可節省92.1%之點擊次數。

With the rapid development of technology and the diverse products, users has higher requirements about the product’s appearance and the mechanism. Therefore, there are kinds of mold parts can be chose, and the size of parts need to be changed since some special requires, resulting in hard to manage the different parts. Because the interference between the template and the parts, the designer should design the escape hole, which is a time-consuming work. This study imports the navigating process in CAD software to the standardize process and led the user to complete the design and combines NET Framework and Structured Query Language (SQL) to build up the mold part standard database on webpage. Changing the parameter in database can achieve the goal of customization. There are three kinds of building parts in Pro/ENGINNEER, which are general type, program type and family table type. This study uses the family table type to create the part samples and applies on the parts that have many sizes. The system will create assembly features and cutting surfaces on parts and this surface corresponds to the size of part on family table. The information will be record by charts and maintained in database controlled via Pro/Web.Link. According to the above, not only can effectively manage the parts, but also with the different needs of the production of customized parts database. Finally, based on the features and surface of parts to assembly and cut automatically so that it can ensure consistency of mold design and designers can reduce time on drawing and assembling. By the mold part database in this study and assembly automatically, the click of mouse in design stage can save 92.1% times.
