Battery wire binding device and method

The invention discloses a battery wire binding device. Horizontal rotating equipment drives a battery pack to horizontally rotate; a lifting assembly of the lifting equipment drives the positioning block with the hole to ascend or descend; a mounting mechanism of the constant-force pay-off equipment is used for mounting a wheel A, a wheel B and a wheel C of a bobbin, and a binding wire is connected to a battery pack through the wheel A, the wheel B, the wheel C, a wheel D and a positioning block with a hole; the wheel C rotates around a fixed point on the constant-force pay-off equipment under the tension, the wheel D is fixed on the conveying frame, and the included angle BCD is a constant value; the brake assembly is used for releasing braking of the bobbin when the pulling force generated by horizontal rotation of the battery pack is larger than or equal to a preset value. The invention further discloses a battery wire binding method, the positioning block with the hole in the lifting equipment ascends or
