Abstract

The invention provides a connecting piece laser processing method based on binocular vision, and relates to the technical field of conductive connection. The method is characterized in that in the connecting process of a conductive piece, the laser power is fed back in real time according to a gray scale step point formed in a depth image by a fusion point when brazing filler metal is fused; in the filling process, the welding speed is optimized according to the gray scale of the depth image; and the speed optimization method is characterized in that the welding motion speed is determined according to the gray scale of the image, the gray scale average value is taken as a base point, the speed is slowed down when being less than the value, and the speed is increased when being larger thanthe value. According to the method, welding track and speed planning is optimized according to the depth image, and the connecting processing efficiency of the conductive piece is improved.

Description

[0001] The invention relates to the technical field of conductive connection (H01R), in particular to a laser processing method for connecting parts based on binocular vision. Background technique [0002] In industrial production, it is necessary to connect different conductive parts. It is necessary to ensure that the resistance of the connection is small. If there are problems such as air bubbles and virtual welding at the connection, the resistance of the connection will increase significantly, and the connection is prone to sparking and heating. The quality of the electrical connection of the conductive parts. [0003] The interconnection of conductive parts can be filled by filling welding, that is, the soldering material is evenly filled in the specified space, and the appearance of the filling is required to be smooth, there are no bubbles in the filling area, and the consistency is good, so as to ensure that the processed product meets specific performance parameters. ...
