Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to an automatic gluing mechanism for wide-width pole pieces. Background Art

[0002] In the automatic winding machine of power lithium batteries, in order to prevent burrs and dust when cutting the pole piece, it is necessary to stick protective tape while cutting the pole piece. The pole piece needs to be cut smoothly without burrs. In order to cut the pole piece with protective tape before entering the final winding area, the pole piece needs to be cut and separated from each other before sticking the protective tape, so as to leave a space for the cutter in the winding area to use.

[0003] There are two electrode clamping mechanisms in front and behind the cutting position, which are responsible for fixing the electrode, and then the cutter cuts the electrode. The two cut electrode sections are fixed by the electrode clamping mechanism and transferred to the protective tape pasting position. The protective tape is sucked by the vacuum adhesive suction plate. When the electrode reaches the pasting position, the protective tape is pasted to the electrode cutting position to complete the process of pasting the protective tape. After pasting, the electrode clamping mechanism is released, the electrode can start to move, and the mechanism returns to the cutting position to wait for the next clamping and cutting of the electrode.

[0004] Since the pole piece clamping mechanism needs to meet the functions of clamping and forward and backward movement at the same time, it occupies a large space. The protective tape preparation parts need to meet the functions of stretching, cutting and grabbing the tape, which also occupies a large space. In addition, pole pieces of different specifications need to be replaced with different specifications of adhesive suction plates. This will cause the user to have a place on site to store different specifications of adhesive suction plates, which wastes time and storage space.

[0005] After the pole piece is clamped, the functions of cutting, pulling apart, and sticking the protective tape need to be completed within a certain area. At the same time, the protective tape needs to be stretched, fixed in length, cut, adsorbed by the vacuum adhesive plate, and pasted to the pole piece. Existing patents have mentioned a way of integrating the cutter, pole piece clamping, and protective tape together to save space, but the structure is complex or the space occupancy is not improved much.

[0006] In summary, the main problems existing in the above-mentioned three components of pole piece clamping and separation, pole piece cutting, and pole piece protective tape are: the structure is relatively complex and occupies a large area within the limited installation space.
