The sheet metal chassis is a key protection structure of the equipment. The sheet metal chassis is equipped with a number of parts, the standard parts type is complicated, and the structure is different. There are currently more artificial visual funding policy assemblies, it is difficult to meet the needs of large-scale industrial production testing. Therefore, it is critical to realize the assembly quality evaluation of sheet metal chassis standard parts.

The image classification is based on the observation and learning of known samples. It has implemented the unknown sample prediction. During the sheet metal chassis assembly quality test, the whole process has technical personnel involvement, which is ideal for image classification mode identification methods. Be

According to the above described, we will assemble the sheet metal chassis assembly process according to the standard zero, and the components are assembled in accordance with the prescribed technical requirements. After commissioning, inspection makes it a qualified product. The model, appearance, etc. of the standard parts, appearance, etc. should be assembled at each assembly position on the sheet metal chassis. There are various standard parts on the sheet metal chassis. During the quality test, the assembly detection results of each assembly location can be summarized as the three cases of correct assembly, misuse, and leakage.

(1) Correct assembly refers to the assembly position, which can be assembled according to the technical requirements of the correct sheet metal chassis standard parts;
(2) Mismatic assembly refers to in the assembly location, the material of the sheet metal chassis is not correct or the quality of assembly is unqualified;
(3) Leakage assembly refers to the correct sheet metal chassis standard parts in the assembly position.
