The application discloses a bus multi-material resistance welding process and a gradient current-distribution electrode structure and belongs to the technical field of resistance welding.The application integrates an electrode quick-change mechanism in a single welding station, can automatically switch a chromium-zirconium-copper inlaid tungsten-copper electrode and a graphite electrode, respectively completes two types of welding procedures of copper braided wire-copper plate and copper plate-L-shaped copper bent plate, adopts a gradient current-distribution electrode with a waist-shaped through groove on a working surface in a matched mode, realizes uniform distribution of current in a large-area welding area with a size of 21*15 mm or above, simultaneously constructs a full-process automatic production line of "welding-air knife cleaning-CCD visual detection-automatic sorting", and effectively solves problems of uneven welding current of large-area copper workpieces, low electrode change efficiency, easy interference of detection by cooling water and the like, electrode switching time is less than or equal to 5 s, the welding point drawing force is stable, the bus welding full-process unmanned operation can be realized, and production efficiency and product consistency are greatly improved.

This invention belongs to the fields of mechanical automation and machine vision recognition technology. It discloses a stability heating test system and method for automated test tube extraction and boundary recognition. The system includes a mechanical motion and gripping unit, a heating and temperature control unit, a machine vision recognition unit, and a central control unit. It enables automatic placement and retrieval of test tubes between the placement and heating positions, precise control of the test temperature and over-temperature protection, and automatic recognition of the endpoint of test paper color change based on machine vision. The method achieves intelligent determination and alarm of the color change endpoint through image acquisition and processing, multi-test tube positioning, test paper area extraction, and color similarity analysis based on HSV color space and Mahalanobis distance. This invention solves the problems of low efficiency, large subjective error, and high safety risks in traditional manual operation, realizing full automation, digitalization, and unmanned operation of the stability heating test process, and improving the accuracy and repeatability of test results.
