specific Embodiment approach
[0057] In one example, see Figure 4 and Figure 5 , as a specific embodiment of the winding group mechanism provided in this application, the shaft drive assembly 8 includes a shaft power unit 81 installed on the frame 100, an output shaft 82 connected to the shaft power unit 81 at one end and a connecting transmission sleeve 73 and the transmission belt 83 at the other end of the output shaft 82 . With this structure, when the shaft power unit 81 drives the output shaft 82 to rotate, the output shaft 82 can respectively drive the transmission sleeves 73 to rotate through the transmission belt 83, and then can drive the rotation shafts 71 and the needle winding assembly 200 to rotate, which can realize the winding Winding of diaphragm and pole pieces at the station. A rotating wheel (not shown) for guiding the movement of the transmission belt 83 is arranged on the second turntable 612, and a limiting groove is provided along the circumference of the rotating wheel, and the...

The application provides a winding group mechanism, which includes a machine frame, a needle winding assembly, a turret, a rotating shaft assembly, a rotating shaft driving assembly, a needle narrowing unit, a needle output unit, a glued needle blocking assembly and a turret driving assembly. In this application, the turret drive assembly can drive the turret to rotate, thereby driving the needle roll assembly to cycle through the needle narrowing unit, needle output unit and glue stopper assembly to realize position conversion between multiple stations, and through the rotating shaft The driving assembly drives the rotating shaft assembly and the needle rolling assembly to rotate, and the diaphragm and pole piece can be wound into a battery cell; the needle-out and needle-retracting operations of the needle winding assembly can be realized through the needle narrowing unit and the needle output unit, and the clamping of the diaphragm and the needle can be realized. The function of removing the battery core; the rotating shaft assembly can be resisted by the adhesive blocking pin assembly, which can avoid the movement of the rotating shaft assembly during adhesive application. Therefore, the winding group mechanism can realize multi-station position adjustment and multi-station operation of the winding needle assembly, thereby reducing the working time at each station and improving the production efficiency of the battery cell.
Description
technical field [0001] The present application belongs to the technical field of lithium battery manufacturing, and more specifically relates to a winding device for preparing a square lithium battery, especially a winding group mechanism. Background technique [0002] In the field of lithium battery processing technology, the battery cell is an important component that determines the quality of lithium batteries. The battery core is formed by clamping the diaphragm through the needle winding assembly and winding the pole pieces together. The winding needle assembly removes the wound and formed battery core when the needle is narrowed. Since the needle winding assembly needs to complete multiple actions such as needle output, winding, and narrowing, the work of the needle winding assembly at each station takes a long time, and the efficiency of preparing batteries is low, which cannot meet market demand. Contents of the invention [0003] The purpose of the embodiments of...
