Description

technical field [0001] The invention relates to a precision assembly detection device for miniature parts and components based on a double CCD industrial camera. Background technique [0002] In the consumer electronics industry and the automotive industry, it is often necessary to assemble tiny parts. The traditional manual assembly method is far from meeting the industry's requirements for assembly accuracy and assembly efficiency. After the assembly is completed, the manual operation of the three-coordinate measuring machine is mainly used to detect the assembly results, which is slow and expensive. [0003] At present, the assembly accuracy of micro-miniature components is mainly guaranteed by positioning fixtures. The conventional method is to use the positioning mold to first position the first part, and then use the auxiliary positioning jig to guide the second part to move to the first part and assemble with the first part. The accuracy of assembly depends on the p...

Problems solved by technology

[0004] First: The high-precision positioning molds required for precision assembly are costly and highly specific;

[0005] Second: In the production line production process, the positioning accuracy is often inversely proportional to the pick-and-place speed. The higher the positioning mold accuracy, the more difficult it is to pick and place (small gap), that is, the longer the detection time of each product, it often cannot meet the production requirements. Line Beat Requirements

Among them, the selection and arrangement of the light source will ultimately affect the detection accuracy of the industrial CCD
