Since the first platform 111 and the second platform 112 are respectively disposed on the first elevation driving assembly 113, the first elevation driving assembly 113 can drive the first platform 111 and the second platform 112 to ascend or descend synchronously.

In this way, after the first adhesive feeding assembly is used for delivering the adhesive tape, the first platform 111 and the second platform 112 can be driven to synchronously rise through the first lifting driving assembly 113, so that the second platform 112 rises to a level height corresponding to the upper end of the battery cell 100, the second adhesive feeding assembly is convenient to continue delivering the adhesive tape, and in the process, a worker can replace the adhesive tape roll on the first adhesive feeding assembly.

Accordingly, after the second adhesive feeding assembly is used for delivering the adhesive tape, the first platform 111 and the second platform 112 can be driven by the first lifting driving assembly 113 to synchronously lift down, so that the first platform 111 descends to a level height corresponding to the upper end of the battery cell 100, the first adhesive feeding assembly is convenient to continue delivering the adhesive tape, and in the process, a worker can replace the adhesive tape roll on the second adhesive feeding assembly.

In some embodiments, as shown in fig. 8 and 9, in order to facilitate replacement of the adhesive tapes on the first and second adhesive feeding assemblies, the first and

second platforms

111 and 112 of the present embodiment are movably disposed on the first lift driving assembly 113 along the first direction, respectively.

Meanwhile, the plurality of battery cells 100 are arranged on the battery cell carrier 10 along the second direction, and by setting the first direction to be perpendicular to the second direction, the occupation space of the first platform 111 and the second platform 112 along the second direction can be reduced. The second direction is the moving direction of the cell carrier 10.

In the process of pulling and holding the adhesive tape, the clamping mechanism 133 is separated from the adhesive tape, and after the adhesive tape is pulled and held for a preset length, the adhesive tape between the clamping mechanism 133 and the battery cell 100 can be sheared by the shearing mechanism. Because the adhesive tape to be pulled is attached to the peripheral wall of the battery cell 100 at the end close to the clamping mechanism 133, the rotation of the battery cell 100 is driven by the rotation pressure head 152 of the rotation assembly 15, so that the adhesive tape can be wound around the peripheral wall of the battery cell 100.

Then, the cell carrier 10 is controlled to move between the lifting rack 11 and the fixed support 12, so that the adhesive tape pulled by the clamping piece 143 is attached to the peripheral wall of the cell 100 on the cell carrier 10 at one end close to the clamping mechanism 133, and at this time, the shearing mechanism is controlled to shear the adhesive tape between the clamping mechanism 133 and the cell 100.
