Embodiment Construction

[0019] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:

[0020] figure 1 It is a flowchart of a method for generating a computer-aided product assembly sequence proposed by the present invention, including:

[0021] Step 1. Based on the hierarchical task network planning method, construct the product assembly knowledge base structure;

[0022] Step 2, the virtual assembly binding process, guided by the hierarchical structure of the virtual assembly and the connection structure of the components, binds the actual components to the corresponding virtual components of the virtual assembly;

[0023] Step 3, generate product assembly sequence based on virtual assembly binding.

[0024] figure 2 is a schematic diagram of the structure of the product assembly knowledge base, in figure 2 In , the structure of the product assembly knowledge base is composed of four parts: component collection, assembly hierarchy, tas...

Abstract

The invention discloses a computer subsidiary product assembling sequence generation method, belonging to the computer aided manufacturing technical field; the method comprises the following steps: firstly based on a layering task net programming method, building a product assembling knowledge base structure; secondly, virtual assembling body binding process, namely, using the layering structure of the virtual assembling body and the connecting structure of components and parts as a guide, binding the real components and parts to the corresponding virtual components and parts of the virtual assembling body; and finally generating the bound product assembling sequence based on the virtual assembling body; wherein the product assembling knowledge base structure comprises four knowledge modules which are of components and parts collection, assembling body layering structure, task layering and task decomposition strategy. The generation method can cause the structure of the product assembling sequence planning knowledge base to become clearer and be easily understood, the layering design of the task and the decision of decomposition tragedy to be more methodic and pertinence, thus increasing the generative flexibility and efficiency of the product assembling sequence and promoting the application of the computer subsidiary product assembling sequence in the intelligent manufacturing field.

Description

technical field [0001] The invention belongs to the technical field of computer-aided manufacturing, and in particular relates to a method for generating a computer-aided product assembly sequence. Background technique [0002] Assembly is an important link in the product manufacturing process. The efficiency and quality of assembly have a great impact on the manufacturing cost and final quality of the product. Automatic generation of product assembly sequence (ASP) is one of the important tasks of computer-aided assembly planning (CAAP). Because the ASP problem is an NP-hard problem, the research on this technology is very active at home and abroad in recent years. [0003] Intelligent planning (AI Planning) is an important and active branch of artificial intelligence research, which aims to automatically or semi-automatically generate an action sequence that meets the requirements (called a plan or plan) in an intelligent way. Intelligent planning has broad application p...
