According to the automatic soldering machine mechanical arm coordinate transformation model with the rotating shaft, transformation from circuit board drilling design coordinates to mechanical arm coordinates corresponding to circuit board welding spots is established, a solder tip automatically reaches the specified welding spot position in a specified posture in a graphic operation mode, and teaching programming efficiency is improved.

Description

technical field [0001] The invention relates to an automatic soldering machine teaching and programming method based on a model and a numerical control drilling file, and belongs to the technical field of automatic soldering of soldering machines. Background technique [0002] The automatic soldering machine is mainly used in the electronics manufacturing industry, especially for the soldering of connectors in the SMT back-end process of the mixed circuit board. The automatic soldering machine includes two parts: the soldering system and the robotic arm. The soldering system mainly includes automatic tin feeding mechanism and welding torch (temperature control, heating element, soldering iron head). There are mainly three-axis systems and four-axis systems for robotic arms. The three-axis automatic soldering machine moves the X-axis (left and right), Y-axis (front and rear), and Z-axis (up and down), and there will be welding dead spots. The four-axis automatic soldering ...

The three-axis automatic soldering machine moves on the X-axis (left and right), Y-axis (front-to-back), and Z-axis (up and down), and there will be welding dead ends

The disadvantages of this method are: first, the established coordinate transformation relationship is the corresponding relationship between the welding layer image in the Gerber file graphics and the actual solder joints, and there is randomness when taking points on the Gerber welding layer image, which cannot be guaranteed The consistency of coordinate values ​​will affect the accuracy of the corresponding relationship between image coordinates and physical coordinates, which in turn will affect the efficiency of teaching programming; second, this method does not support automatic soldering machines with rotating axes
