Compact bus bar centralizing device

The utility model relates to the technical field of photovoltaic module processing, and particularly discloses a compact bus bar centralizing device which comprises a support, a centralizing assembly and a lifting mechanism. The centralizing assembly comprises two connecting supports arranged oppositely, two X-direction centralizing blocks, two Y-direction centralizing blocks, an X-axis driving piece and a Y-axis driving piece. The lower ends of the two connecting brackets are folded towards the center; the two X-direction centralizing blocks can limit the two inner side faces of the bus bar and the two end faces of the bus bar in the width direction. The two Y-direction centralizing blocks can limit the two outer side faces of the bus bar. The X-axis driving part can drive the two connecting supports to move oppositely in the width direction of the bus bar together. The Y-axis driving piece can drive the two Y-direction centralizing blocks to move towards or away from the two X-direction centralizing blocks
