[0033] By using the technical scheme of the utility model, after the grabbing mechanism 1 grabs the electric core 40 by using the suction assembly 12, the pressing-down mechanism 2 drives the pressing plate 22 to descend by using the lifting assembly 21, and the pressing plate 22 presses down the tab 41 of the electric core 40, so as to realize the flattening of the tab 41 or control the degree of the tab 41 being raised within the allowable range. The pressing-down device 10 of the utility model does not need to carry the electric core 40 to the special pressing plate 22, so the working efficiency is high, and the production efficiency of the electric core is improved.

[0034] In some embodiments, as shown in Figure 1 and 2 , the suction assembly 12 is provided in multiple groups, and the multiple groups of suction assemblies 12 are arranged at intervals along a first direction X. The first direction X is the interval direction of the multiple groups of suction assemblies 12 and is usually also the length direction of the mounting plate 11.
