Problems solved by technology

Due to the difference in tab welding or cutting accuracy, the tabs of the battery core may be misaligned after winding, which will affect the quality of the battery core. Therefore, the winding equipment needs to be equipped with a needle winding mechanism that can change the circumference of the winding needle.
[0003] The current needle rolling mechanism can change the circumference of the needle, but most of the structures are more complicated, and it is inconvenient to adjust the circumference of the needle

Embodiment Construction

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] like figure 1 , figure 2 As shown, the winding device in this embodiment includes a turret 100 that rotates around an axis, and three stations are evenly arranged on the circumference of the turret 100 with the axis as the center, namely the winding station 110 and the gluing station 120 And the blanking station 130, the angle between each station is 120 degrees. Each station is provided with a needle winding mechanism 200. When the turret 100 rotates around its axis, it can drive the needle winding mechanism 200 to switch positions in sequence between different stations, so as to complete the winding, gluing, and unloading of the cell. operate. The needle winding mechanism ...

Abstract

The invention discloses a winding device and a winding method. The winding mechanism comprises a rotating tower, three winding needle mechanisms are arranged on the rotating tower and correspond to a winding station, a rubberizing station and a discharging station respectively, and a motor needle opening assembly, a needle closing assembly and a needle opening and closing adjusting assembly are further arranged on the rotating tower. The motor needle opening assembly is arranged at a winding station and drives the winding needle mechanism to clamp a material belt; the needle closing assembly is arranged on the discharging station and drives the winding needle mechanism to loosen the material belt. A first adjusting assembly matched with the opening and closing needle adjusting assembly is arranged on the outer surface of the winding needle mechanism, and the opening and closing needle adjusting assembly is arranged on the discharging station and matched with the first adjusting assembly to adjust the perimeter of the winding needle mechanism. According to the winding device and the winding method, the winding precision of the battery cell can be improved while the working efficiency is ensured.

Description

technical field [0001] The invention belongs to the field of lithium battery automation equipment, and in particular relates to a winding device and a winding method. Background technique [0002] The production of the battery cell is to wind the positive electrode sheet material strip, the negative electrode sheet material strip and the diaphragm material strip in turn to form a winding body, and the tab is a metal conductor that leads the positive and negative electrodes from the battery core. Due to the difference in the welding or shearing precision of the tabs, the tabs of the cells may be dislocated after winding, which will affect the quality of the cells. Therefore, the winding equipment needs to be equipped with a winding mechanism that can change the circumference of the winding needle. [0003] The needle rolling mechanism currently used can change the circumference of the rolling needle, but most of the structures are complicated, and it is inconvenient to adjust...
