[0002] During the winding process, insert pins are primarily used to secure materials such as electrodes and separators, ensuring they remain accurately positioned and prevent shifting during the winding process. They facilitate efficient and precise winding, thereby ensuring product quality and performance. Therefore, insert pins are a crucial component of lithium battery winding machines, significantly impacting battery quality and lifespan. Due to the frequent insertion operations required, insert pins are typically made of high-strength, wear-resistant materials to ensure their longevity.

[0003] The existing winding insert needle is usually composed of an insert needle slide shaft, an insert needle, a screw and other structures. For example, the double-insert needle winding mechanism of the lithium battery winding machine with the prior art announcement number CN214411295U includes a reel body, which is composed of an outer shaft, a middle shaft and a winding needle joint connected longitudinally in sequence. The first insert piece and the second insert piece are respectively provided at the longitudinal ends of the winding needle joint, and a first insert piece slider and a second insert piece slider are provided between the middle shaft and the winding needle joint.

[0004] The insert needle of a traditional winding machine is first installed on the insert needle slide shaft by screws, which is located next to the winding needle, and then the winding needle connector is assembled. When installation, repair or replacement is required, the winding main needle connector needs to be removed first, and then the screws need to be removed, which is very cumbersome and invariable. Based on this, the utility model provides a winding insert needle quick disassembly and assembly structure that is easy to operate. Utility Model Content

[0016] The technical effects and advantages of this utility model are:

[0017] The winding insert needle is inserted from the guide groove of the handle, and the outer protrusion of the clamp head is compressed, causing the elastic arm to be compressed to the inner retracted avoidance position. When the outer protrusion of the clamp head of the winding insert needle reaches the clamping head position, the elastic arm restores its deformation so that the outer protrusion of the clamp head is engaged with the clamping head position, thereby realizing the rapid insertion of the winding insert needle. When the winding insert needle needs to be removed, force is applied in the direction away from the clamping head position, so that the outer protrusion of the clamp head is compressed, and then the elastic arm is compressed to the inner retracted avoidance position, and the outer protrusion of the clamp head enters the guide groove of the handle, thereby realizing the rapid disassembly and assembly of the winding insert needle.
