The invention relates to a winding needle device and winding equipment. The winding needle device comprises a rotating mechanism which can controllably rotate around a first rotating axis; a winding needle mechanism which comprises a winding needle seat, a first winding needle and a second winding needle, wherein the first winding needle and the second winding needle are oppositely arranged on the winding needle seat, the winding needle seat is connected to the rotating mechanism, and the first winding needle can move relative to the winding needle seat in the direction close to or away from the second winding needle. The winding needle mechanism further comprises a first driving piece which is movably connected to the winding needle base in the first direction parallel to the first rotating axis and a first driving matching piece connected to the first winding needle, wherein the first driving matching piece is matched with the first driving piece, and the first winding needle is driven to be close to or far away from the second winding needle in response to movement of the first driving piece in the first direction; and an adjusting mechanism which is arranged on the rotating mechanism and is in transmission connection with the first driving piece, wherein the adjusting mechanism is controlled to drive the first driving piece to move in the first direction.
Description
technical field [0001] The invention relates to the technical field of battery manufacturing equipment, in particular to a needle winding device and winding equipment. Background technique [0002] During the preparation process of battery cells, winding equipment is generally used to wind material strips such as pole pieces and separators to form battery cells. In the actual production process, it is often necessary to frequently adjust the circumference of the winding needle (that is, adjust the circumference by adjusting the radial dimension of the winding needle) to ensure the tab alignment of the produced battery core. However, in the prior art, the purpose of adjusting the circumference of the needle is often achieved by sticking a Teflon sheet on the needle, which takes a long time to operate and reduces the production efficiency. Contents of the invention [0003] Based on this, it is necessary to provide a method for improving the above-mentioned defects in view ...
