Abstract

The invention discloses an electrolytic cell small chamber assembly line detection method and device, and relates to the technical field of airtightness detection.The method comprises the steps that an electrolytic cell workpiece is fixed to a fixing tool of a conveying module; the detection module confirms that the electrolytic cell workpiece reaches a preset position through a visual positioning unit; the detection module is used for filling the electrolytic cell workpiece with compressed gas through a filling probe of a gas filling unit; the detection module acquires an infrared image after the electrolytic cell workpiece is filled with the compressed gas through an infrared acquisition unit; and a data analysis unit of the detection module carries out image comparison and analysis on the infrared image and a standard infrared image to obtain a detection result. The normal-temperature workpiece is filled with the compressed gas, infrared image airtightness detection is achieved, the small gap detection capacity is high, the method is more suitable for flow line production, the hollow part in the workpiece is filled with the compressed gas through the filling probe, and infrared image abnormity caused by contact between an air nozzle and the workpiece during inflation is avoided.
