A collating unit of an electric energy meter comprises a mounting plate, and a pair of parallel mounting supports is arranged below the mounting plate. A first linear bearing and a second linear bearing parallel to the first linear bearing are arranged on the mounting plate, a first guide shaft is arranged on the first linear bearing, and a second guide shaft is arranged on the second linear bearing. A stopping air cylinder is arranged at the position, between the first linear bearing and the second linear bearing, of the mounting plate, and the position, between the first guide shaft and thesecond guide shaft, of the lower portion of the mounting plate is connected and provided with an electric energy meter baffle. A meter stirring air cylinder mounting frame is arranged below the mounting plate, a meter stirring air cylinder is arranged on the meter stirring air cylinder mounting frame, and the meter stirring air cylinder is connected and provided with a first electric energy meterstirring plate and a second electric energy meter stirring plate parallel to the first electric energy meter stirring plate. According to the collating unit, the problem that in the prior art, bare meters of multiple sizes cannot be conveyed to the position in front of a special machine, and the electric energy meters cannot be located is solved, the electric energy meter conveying efficiency is greatly improved, and the transportation cost is reduced.
