Embodiment 1

[0073] Such as figure 2 As shown, through the method of generating the assembly matrix, listing figure 2 The three assembly matrices of the assembly composed of 4 parts: assembly connection matrix C, assembly support matrix G, and assembly interference integration matrix IN are as follows:

[0074] C = 0 0 1 1 0 0 1 1 1 1 0 1 1 1 1 0 ; G = 0 0 1 1 0 0 1 0 1 0 0 0 0 0 0 0 ; IN = 0 0 7 6 2 0 7 2 5 5 0 5 7 0 7 0 ,

[0075] Then according to the determination of the reference part, the sum of the rows of the fourth row of the assembly support matrix G is zero, then the part 4 can be determined as the reference part, and 4 is stored in the set VP storing the assembled parts.

[0076] Use candidate parts screening rules to find parts that have ...

Embodiment 2

[0084] See image 3 , Through the method of generating assembly matrix, list image 3 The assembly connection matrix C, assembly support matrix G, and assembly interference integration matrix IN of the assembly composed of 11 parts are as follows:

Abstract

The invention discloses an assembly sequence planning method of a complex assembly on the basis of an assembly matrix in the field of the automatic assembly sequence planning of products. A general generation method of the assembly matrix is used for obtaining an assembly connection matrix, an assembly supporting matrix and an assembly interference integration matrix; and through the assembly supporting matrix, a reference element is determined and is stored into a set where an assembled part is stored, a candidate part is determined and is stored into the set where the candidate part is stored, a gravity supporting part is obtained through the assembly supporting matrix, and an assembly direction is determined through the assembly interference integration matrix. Through the classification of the assembly direction, a product assembly sequence which can be used for an automatic production line is directly obtained, the automation level of the production line can be improved, efficiency on the assembly sequence planning of the complex assembly is improved, an error ratio is lowered, assembly cost is lowered, and a production period is shortened.

Description

Technical field [0001] The invention relates to the field of automatic assembly sequence planning of products, in particular to an assembly sequence planning method of a complex assembly. Background technique [0002] Product assembly costs account for about 40% to 50% of product manufacturing costs. Product assembly sequence planning is a key technology for automatic product manufacturing; traditional assembly sequence planning for complex assembly products is mainly in the CAD system, according to the detachable On the principle of ready-to-install, the product is disassembled and then assembled to obtain the product assembly sequence. [0003] The disassembly method is to disassemble the assembly according to the established disassembly rules after the assembly model is assembled, and record the assembly constraint relationship of the disassembled parts and other parts in the constraint table, and record the disassembly parts that encounter interference during disassembly in In...
