Assembly method of printed circuit board and FPC flexible cable and related equipment

Abstract

The invention discloses an assembly method and related equipment for a printed circuit board and an FPC flexible cable, and the assembly method comprises the steps: selecting a robot base world coordinate as a basic coordinate system, and obtaining a pose relation between the basic coordinate system and an image coordinate system through an offline calibration algorithm; pixel coordinates of the assembly parts on the printed circuit board and the FPC flexible cable are obtained through positioning, the pixel coordinates are converted into the basic coordinate system through the pose relation, and a compensation difference value between the converted pixel coordinates is obtained; and the manipulator moves according to the compensation difference value to complete the assembly between the printed circuit board and the FPC flexible cable. According to the method, the position and posture relation between the basic coordinate system and the image coordinate system is established, the recognized pixel coordinates of the assembly materials are converted into the unified coordinate system for difference calculation, then the manipulator is controlled to conduct precise difference compensation operation, and therefore high-efficiency precise assembly is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical assembly, and in particular relates to an assembly method of a printed circuit board and an FPC flexible cable and related equipment. Background technique [0002] Improving efficiency and reducing manpower are the needs and trends of social development, especially in industrial production, and the process of product assembly is generally required in the processing of industrial products. Therefore, assembly plays a very important role in the entire product processing process. effect. In the current product assembly, the staff need to manually assist the whole process of mounting parts assembly. The manipulator completes all the assembly according to the predetermined route. The labor intensity of the personnel is high, the work efficiency is low, the production cost is high, and there are problems with the assembly accuracy. There is a coordinate deviation between the center point during asse...

Problems solved by technology

In the current product assembly, the staff need to manually assist the whole process of mounting parts assembly. The manipulator completes all the assembly according to the predetermined route. The labor intensity of the personnel is high, the work efficiency is low, the production cost is high, and there are problems with the assembly accuracy. There is a coordinate deviation between the center point during assembly and the assembly on the material, which will further lead to low accuracy
