[0002] There are generally three types of rolls used in stacking machines, namely, diaphragm rolls, positive electrode rolls, and negative electrode rolls. When the rolls are about to run out, a new roll needs to be replaced, and then the head end of the roll in the new roll is connected to the end of the roll in the old roll.

[0003] When connecting the old and new tapes, an existing method is to manually stick tape on the end of the tape on the new roll, then adsorb the tape with tape on the adsorbent, and then press the tape on the adsorbent against the old tape, and use the tape to stick the new tape to the old tape to complete the connection between the old and new tapes. The adsorbent used in this method has adsorption holes on its surface, and the tape is adsorbed through the adsorption holes, while the tape exposed from the end of the tape is directly attached to the adsorbent. For an adsorbent with this structure, when the tape is detached from the adsorbent, the tape is easily attached to the adsorbent, causing the end of the tape to adhere to the adsorbent, affecting the connection between the old and new tapes.

[0037] The material strip adsorption mechanism 1 at least includes a adsorption roller 10 .

[0038] The adsorption roller 10 includes a roller shaft 11 and a roller 12 mounted on the roller shaft 11, and the surface of the roller 12 is sequentially arranged with an adsorption area 121 and an anti-sticking area 123 along the circumferential direction;

[0039] The adsorption area 121 is configured to adsorb the head end of the material tape, and a portion of the tape extending from the end of the material tape is located in the anti-adhesion area 123 .

[0040] When the material strip adsorption mechanism 1 is in use, negative pressure is formed in the roller 12 of the adsorption roller 10 , so that the material strip can be adsorbed through the adsorption area 121 .

[0041] The material strip is adsorbed by a cylindrical adsorption roller 10, and an adsorption area 121 and an anti-sticking area 123 are arranged on the roller 12 of the adsorption roller 10. The adsorption area 121 adsorbs the head end of the material strip, and the anti-sticking area 123 prevents the adhesive tape from adhering the end of the material strip to the roller 12, so that the material strip can be smoothly detached from the roller 12.

[0042] The adsorption region 121 may have various structures.

[0043] A first embodiment of the adsorption area 121 includes a row of adsorption holes opened on the surface of the roller 12 along the axial direction.

[0044] The adsorption area 121 adopts a row of adsorption holes, which has a simple structure and is easy to manufacture.

[0045] The second embodiment of the adsorption area 121 includes a plurality of rows of adsorption holes opened on the surface of the roller 12 along the axial direction, and two adjacent rows of adsorption holes are arranged alternately.

[0046] The adsorption area 121 adopts multiple rows of adsorption holes, which increases the adsorption area and makes the adsorption more reliable.
