The invention discloses an online inspection and cleaning device of batteries. The online inspection and cleaning device comprises a frame, a first conveying belt, a second conveying belt and an isolation hood, wherein the first conveying belt is arranged on an
operating table of the frame and is used for bearing to-be-inspected batteries, the second conveying belt is used for bearing qualified batteries, the isolation hood is arranged on the
tail end of the second conveying belt, an inlet and an outlet are correspondingly formed in the front and back parts of the isolation hood, at least one group of cleaning
brush which is driven to rotate is correspondingly arranged in the ends, which are opposite to anodes and cathodes of the batteries, in the isolation hood, and the isolation hood is communicated with a vacuum device by virtue of a communicating
pipe. According to the online inspection and cleaning device, a conveying belt type
workbench is redesigned, and an online cleaning and dust removing device of the batteries is additionally arranged, so that the
assembly line work can be realized, and the operations are completed by different operators according to different functions. The actual
operation time and efficiency of different posts are measured, so that the number of operators of each post is reasonably arranged, the online cleaning and dust removing device is used for replacing manual operation, the purpose of increasing the efficiency by downsizing payrolls is realized, additionally, the previous and subsequent operation beats are balanced, the
maximum efficiency is achieved, the scale production is facilitated, and the application range is wide.
