The invention discloses a fully automatic battery code spaying grouping device for solving the problems of high labor intensity, low efficiency, high rate of defective products and the like in processes of code scanning, testing, code spaying as well as sorting and collection of semi-finished batteries. Compared to the prior art, the fully automatic battery code spaying grouping device achieves the online production of the processes of feeding, code scanning, testing, code spaying as well as sorting and collection of the semi-finished batteries to achieve automation, is high in efficiency to facilitate the maintenance of the consistency of product quality, integrates multiple processes needing to be completed by multiple workers with multiple devices previously into a single device to greatly save labors, most importantly, improves production efficiency and yield, is small in size and occupation area, avoids the occupation of workshop space by semi-finished batteries due to the fact that the processes of feeding, code scanning, testing, code spaying as well as sorting and collection of the semi-finished batteries are completed at one time, and can be combined with a battery production line to achieve the on-line production from battery raw materials to finished battery products.
