[0026] The utility model discloses a tape unwinding mechanism for actively unwinding a whole roll of tape, completing the fixed-length cutting of the tape, the tape taking mechanism cooperates with the tape unwinding mechanism to absorb the cut tape, and the sucked tape is transferred to the gluing station by a robot arm, the tape sticking mechanism is used to stick the tape on the welding surface of the tab, the battery cell positioning mechanism can realize rapid positioning of the battery cell during loading, and fixes and presses the battery cell by a cylinder to avoid the battery cell from moving in a rapid movement and during gluing, thereby achieving consistency in gluing.

[0027] Figure 2 yes Figure 1 Partial schematic diagram, Figure 3 yes Figure 2 Another angle diagram shows that the glue unwinding part includes a film 101 and a plurality of transition rollers 102.

The rubber-pulling thumb cylinder controls the opening and closing of the rubber-pulling clamp 107 to clamp the tape, and the rubber-pulling cylinder drives the rubber-pulling thumb cylinder to move up and down. When the tape arrives, the clamp clamps the tape and then pulls it downward under the control of the rubber-pulling cylinder.

[0036] The cell positioning and transport mechanism primarily consists of a cell positioning and clamping mechanism and a mobile manipulator. The cell positioning mechanism enables rapid positioning of the cells during loading and secures and clamps the cells using a pneumatic cylinder, preventing them from shifting during rapid movement and gluing, ensuring consistent gluing. The mobile manipulator is used to quickly switch between the loading and unloading stations and the two tab gluing stations.
