Abstract

The invention provides a winding needle driving device, a winding head and a winding machine, and relates to the technical field of lithium battery equipment. The winding needle driving device comprises a winding needle shaft and a magnetic driving mechanism. Wherein the winding needle shaft can be sequentially switched among a plurality of stations; the magnetic driving mechanism is arranged at one end of the winding needle shaft and comprises a rotor and a plurality of stators, the rotor is fixedly connected with the winding needle shaft, the stators and the stations are fixed on a rack of the winding needle driving device in a one-to-one correspondence manner, and the stator on any station is suitable for being in driving connection with the rotor and is used for driving the winding needle shaft to rotate. The rotary inertia of the reel can be reduced, the energy consumption of the winding machine is reduced, a high-power and large-specification magnetic driving mechanism can be selected, and the production efficiency of the winding machine is improved; the magnetic driving mechanism is of a non-contact type, fixed-point driving is achieved, one magnetic driving mechanism can drive the winding needle shafts to rotate, the number of driving devices is reduced, and cost is saved.

Description

Technical field

[0001] The present invention relates to the technical field of lithium battery equipment, specifically to a needle reeling device, a winding head and a winding machine. Background

[0002] In the existing lithium battery production equipment, the drive mode of the needle reel is contact type, one of which is that the winding motor that drives the needle rotation is directly mounted on the reel, and the winding motor is directly connected to the needle shaft. In this scheme, the winding motor is flipped together with the reel, causing the moment of inertia of the reel to become larger, affecting the rolling speed, increasing the energy consumption of lithium battery production equipment, and reducing production efficiency. Moreover, each needle reel is directly connected to a winding motor, limited by the assembly space, the winding motor can only use smaller specifications, smaller power, so that the production efficiency is limited and the production capacity is...
