| Abstract: |
| A system for fully automatic selection of welding specifications in resistance welding equipment has been developed to address the problem of workers frequently choosing the wrong specifications during manual welding of multiple parts on a single machine in automobile factories. The system incorporates an automatic recognition system for different workpiece materials using the added machine fixture, visual detection system for nuts and bolts, and secondary graphical confirmation to ensure the correctness of specification calling. This system achieves reliable, fully automatic selection of welding specifications in resistance welding equipment and has shown significant effects in improving welding quality for mass-produced workpieces, while solving the problem of specification calling errors that can occur with traditional methods involving process charts and code adjustments. This system is particularly suitable for promoting applications in manual welding of multiple parts on a single machine in automobile factories, ensuring correct specification calling and welding quality. |

| 针对汽车厂座点焊机一机多件手工焊接中工人容易选错规范的问题，设计了一种电阻焊设备全自动规范选择的系统。通过增加的机台夹具自动识别系统实现了对不同母材工件的识别；通过引入螺母螺钉视觉检测系统实现了对手件的识别；通过二次图形化确认进一步保证了调用规范的正确性。本系统实现了电阻焊设备焊接规范可靠的全自动选择，在实际应用中取得了显著的效果，有效提升了批量工件的焊接质量，解决了传统的通过工艺图表查找规范后经拨码进行选择时容易发生规范调用错误导致焊接质量的问题。本系统特别适合推广应用于座点焊机一机多件手工焊接中，保证了焊接规范的正确调用，保证了焊接质量。 |
