The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Referring to fig. 1 to 14, an automatic cutting and stacking device for ferrite green sheets according to an embodiment of the present invention is used for automatically cutting and stacking ferrite green sheets. The automatic cutting and stacking device for the ferrite green sheets comprises a feeding component 10, a cutting and conveying component 20 arranged above the feeding component 10, a trimming component 30 arranged at one end of the cutting and conveying component 20, a slitting component 40 arranged in the middle of the cutting and conveying component 20, a tray conveying component 50 arranged at the other end of the cutting and conveying component 30, positioning components 60 arranged in two opposite sides of the tray conveying component 50, and a suction component 70 arranged above one end of the tray conveying component 50.

The feeding assembly 10 comprises a base 11, two driving rollers 12 arranged in the middle of the base 11, a driven roller 13 arranged above one of the driving rollers 12 in a sliding manner, a first dust removing roller 14 arranged on one side of each driving roller 12, a second dust removing roller 15 arranged on one side of the driven roller 13, a feeding motor 16 arranged at one end of the base 11, a deviation rectifying roller 17 and a deviation rectifying detection seat 18 arranged on one side of the base 11, and a tension swing rod 19 arranged on the other side of the base 11; the feeding motor 16 is used for driving the two driving rollers 12 to rotate.

A ferrite green sheet is arranged between the driving roller 12 and the driven roller 13 in a penetrating way, wherein, a first dust removing roller 14 is abutted against the driving roller 12, and a second dust removing roller 15 is abutted against the driven roller 13; neither the first dust removing roller 14 nor the second dust removing roller 15 directly contacts the ferrite green sheet. Specifically, the first dust removing roller 14 provides the driving roller 12 with adhesive force, the second dust removing roller 15 provides the driven roller 13 with adhesive force, and the driving roller 12 and the driven roller 13 have poor adhesive force. When the ferrite green sheet passes between the driving roller 12 and the driven roller 13, the adhesive force obtained by the driving roller 12 and the driven roller 13 can just adsorb impurities such as dust, but the ferrite green sheet cannot be pulled, so that local deformation is avoided, the smoothness and the precision of conveying are ensured, along with the continuous rotation of the driving roller 12 and the driven roller 13, the impurities such as the dust adsorbed by the driving roller 12 and the driven roller 13 are adsorbed and taken away by the first dust removing roller 14 and the second dust removing roller 15 which have stronger viscosity, and the impurities such as the dust on the ferrite green sheet can be indirectly transferred to the first dust removing roller 14 and the second dust removing roller 15 by repeating the cycle, so that the dust removing effect is achieved.
