隨著機械手臂的應用蓬勃發展，現今自動化生產線常以機械手臂搭配各式夾治具來進行零件組裝，但目前自動化生產線仍有許多前置作業需以人為方式來安排，例如零件組裝的順序及路徑、零件的夾持點…等，本論文透過二次開發工具Creo Toolkit建立一套組裝規劃系統，可直接由零件及組件的3D幾何模型來分析零件的組裝順序及路徑，以減少自動化組裝的前置作業時間。本論文的基本研究方法是先由3D零件的平面和軸線找出可能的零件爆炸方向，然後針對每一個可能的爆炸方向，以射線干涉法確認其可行性，藉以求出零件的爆炸順序及路徑，並自動建立爆炸圖，接著由爆炸圖取得組裝順序及路徑，最後由所得資訊建立組裝模擬的動畫，並使用Epson機械手臂依序組裝零件。
本論文除詳述以組件幾何模型分析組裝路徑及順序之外，也利用鑽頭、卡鉗、檯燈、機車前叉等數個組件作為實例，驗證所開發系統的實用性。

With the rapid application of manipulators, automated assembly lines are relying on multiple manipulators and various types of fixtures. Although the assembly lines nowadays are fully automated, there are still plenty of setups that need to be taken care, such as assembly sequence planning, path planning, grasping points, and so on. This thesis establishes a Creo Toolkit-based assembly planning system, which can generate feasible assembly sequences and assembly paths so as to reduce the time of pre-processing. The basic idea is to find the possible exploded directions of the part to be assembled, which can be extracted from the part’s planar surfaces and axes, and then confirm the feasibility by the ray tracing technique for every single possible exploded direction, so as to generate the exploded sequence and exploded path of the part. An exploded drawing is next automatically established through the output results. Afterwards, the data from the exploded drawing is acquired to build the animation of assembly simulation and Epson manipulator assembles all the components in the sequence.
Besides elaborating on the analysis of assembly sequence and path planning based on the 3D CAD model, this thesis also uses drill, caliper, table lamp, motorcycle’s front fork and various assemblies as examples to verify the practicability of the developed system.
