A gap 40 for conveying the outside pole piece 800 is defined between the first rolling and pasting shaft 10 and the second rolling and pasting shaft 20, and the first rolling and pasting shaft 10 and the second rolling and pasting shaft 20 are driven by the rolling driver 30 to oppositely paste the gummed paper which is respectively absorbed in vacuum on the pole piece 800 which passes through the gap 40. Specifically, as shown in fig. 8 and 9, the first rolling and pasting shaft 10 has a first air flow channel 11 and a first arc rolling and pasting surface 12 with an arc center located on the axial line C1 of the first rolling and pasting shaft 10, and a plurality of first openings 13 spaced from each other and communicated with the first air flow channel 11 are arranged on the first arc rolling and pasting surface 12 to ensure the reliability of the first rolling and pasting shaft 10 for adsorbing the adhesive tape and pasting the adhesive tape on the pole piece 800; the second rolling and pasting shaft 20 is provided with a second air flow channel 21 and a second arc rolling and pasting surface 22 with an arc center positioned on the axis C2 of the second rolling and pasting shaft 20, and a plurality of second openings 23 which are spaced apart and communicated with the second air flow channel 21 are arranged on the second arc rolling and pasting surface 22 so as to ensure the reliability of the second rolling and pasting shaft 20 for absorbing the gummed paper and pasting the gummed paper on the pole piece 800; the rolling driver 30 rotates the second arc rolling surface 22 to the rubberizing position (see fig. 3, 4, and 5) and the first arc rolling surface 12 to the offset position (see fig. 3, 4, and 5) offset from the rubberizing position in the process of driving the first rolling shaft 10 and the second rolling shaft 20 to synchronously roll, so as to sequentially apply the gummed paper to the pole pieces 800 passing through the gap 40, for example, first applying the upper surface of the pole piece 800 and then applying the lower surface of the pole piece 800, or first applying the lower surface of the pole piece 800 and then applying the upper surface of the pole piece 800.

This design effectively prevents the second rolling contact shaft 20 from contacting the pole piece 800 passing through the gap 40 during the rotation process, so as to ensure the reliability of the second arc rolling contact surface 22 of the second rolling contact shaft 20 for adhering the adhesive paper to the pole piece 800 passing through the gap 40. Specifically, in fig. 9, the second opposite surface 24 is provided with a fourth opening 26 communicating with the second airflow channel 21, and preferably, the second middle connecting surface 25 is a plane, but not limited thereto.

As shown in fig. 2-5, the roll taping mechanism 100 further includes a first mounting shaft 50 and a second mounting shaft 60 spaced apart and side by side with each other. The first and

second mounting shafts

50 and 60 are respectively sleeved with a gear 71 and a driving wheel 72, the first axial end 10a of the first rolling contact shaft 10 is sleeved with an engaging wheel 73 aligned with the driving wheel 72 on the first mounting shaft 50, and the first axial end 20a of the second rolling contact shaft 20 is sleeved with an engaging wheel 73 aligned with the driving wheel 72 on the second mounting shaft 60.

Specifically, in fig. 8 and 9, the first air flow channel 11 penetrates through the second axial end 10b of the first rolling contact shaft 10, and the second air flow channel 21 penetrates through the second axial end 20b of the second rolling contact shaft 20, so that the first rolling contact shaft 10 and the second rolling contact shaft 20 are respectively installed in a vacuum device in an access manner, and interference with the mating wheel 73 is avoided. For example, the first transmission member 74 and the second transmission member 75 are belts, and correspondingly, the transmission wheel 72 and the engaging wheel 73 are belt wheels; of course, the first transmission member 74 and the second transmission member 75 can be chains, and correspondingly, the transmission wheel 72 and the engaging wheel 73 are sprockets, so the invention is not limited thereto. Among them, in order to make the arrangement of the rolling driver 30, the first rolling contact shaft 10 and the second rolling contact shaft 20 on the housing 200 more compact, in fig. 1, the first rolling contact shaft 10 and the second rolling contact shaft 20 are located at the front side of the housing 200, and the rolling driver 30 is located at the rear side of the housing 200.

When the first arc rolling and pasting surface 12 of the first rolling and pasting shaft 10 rotates to the glue preparation position, at this time, the first glue pressing mechanism 500a performs glue loosening action, and the first glue pulling mechanism 700a pulls glue in a direction away from the first glue pressing mechanism 500 a; after the first glue pulling mechanism 700a reaches the predetermined position, the first arc rolling and pasting surface 12 adsorbs the glue paper pulled out by the first glue pulling mechanism 700a, the first glue pressing mechanism 500a performs a glue pressing action, the first cutting mechanism 600a performs a cutting action, and the glue paper between the first glue pulling mechanism 700a and the first glue pressing mechanism 500a is cut off, so that the glue preparation process of the first arc rolling and pasting surface 12 of the first rolling and pasting shaft 10 is completed.

Similarly, when the second arc rolling and pasting surface 22 of the second rolling and pasting shaft 20 rotates to the glue preparation position, at this time, the second glue pressing mechanism 500b performs a glue loosening action, and the second glue pulling mechanism 700b pulls glue in a direction away from the second glue pressing mechanism 500 b; after the second glue pulling mechanism 700b reaches the predetermined position, the second arc rolling surface 22 adsorbs the gummed paper pulled out by the second glue pulling mechanism 700b, the second gumming mechanism 500b performs a gumming action, the second cutting mechanism 600b performs a cutting action, and the gummed paper between the second glue pulling mechanism 700b and the second gumming mechanism 500b is cut off, so that the glue preparation process of the second arc rolling surface 22 of the second rolling shaft 20 is completed.

Because the glue preparation of the second rolling and pasting shaft 20 and the glue preparation of the first rolling and pasting shaft 10 are sequentially and alternately realized, in the process that the rolling driver 300 drives the first rolling and pasting shaft 10 and the second rolling and pasting shaft 20 to synchronously rotate, firstly, the glue preparation of the second rolling and pasting shaft 20 pastes the gummed paper on the lower surface of the pole piece 800 penetrating through the gap 40, and then, the glue preparation of the first rolling and pasting shaft 10 pastes the gummed paper on the upper surface of the pole piece 800 penetrating through the gap 40, so that the purpose of pasting the gummed paper on the upper surface and the lower surface of the pole piece 800 penetrating through the gap 40 is realized.
