Welding temperature uniformity detection device for series welding machine

The utility model provides a welding temperature uniformity detection device for a series welding machine, which relates to the technical field of photovoltaic production equipment and comprises a workbench and a plurality of guide rails, a moving block is slidably arranged in each guide rail, and a second motor is fixedly mounted on the outer surface of one side of each guide rail. The output end of the second motor slidably penetrates through the outer surface of the guide rail and extends into the guide rail, and a threaded rod is fixedly mounted at the output end of the second motor. In the welding process, due to the fact that the temperature sensor is located above the welding strip and can synchronously move backwards along with the electrode, the temperature of the welding position can be comprehensively detected in real time, detection dead angles are avoided, the uniformity of the welding temperature is effectively detected, and the welding quality is improved. And the second motor is started to dri
