Problems solved by technology
In this structure, when the winding motor 43 receives the signal to run, because there is a gap between the two stages of transmission, the state when it is driven to the winding needle and when the signal is given is delayed by the time of the two transmission gaps, resulting in a corresponding lag; at the same time Due to the cumulative transmission of the gap, the quality of the actual rolled-out battery core is also not good.
When making square cells, under high-speed conditions, rapid speed changes have higher requirements for transmission clearance and response time, and two-stage transmission is difficult to meet the requirements
[0005] To sum up, in the two-stage transmission method in the prior art, problems such as twisting and knotting of motor wires and signal wires will occur during the transmission process; at the same time, there are problems such as large cumulative error of transmission and lag in response. Especially in the case of winding square cells, it seriously affects the winding efficiency and winding quality

The present invention provides a winding head mechanism, which includes: a base, a slip ring, a follower plate, a position changing motor and at least one winding body, the slip ring includes a rotor and a stator that can rotate with each other, and the stator It is fixed on the limit bracket; the follower plate is fixedly connected with the rotor of the slip ring, and the follower plate can rotate relative to the main supporting part. The winding head mechanism provided by the present invention solves the problem of cable knotting in the prior art through the rotatable cooperation between the rotor and the stator in the slip ring; The motor directly drives the winding drive shaft to rotate, and then drives the winding needle to work, which can reduce the transmission gap and error, and at the same time can greatly improve the response speed, improve the winding quality and efficiency; in addition, it is more conducive to high-speed variable speed control, The production efficiency will be greatly improved, and the equipment cost and production cost will be reduced.
Description
technical field [0001] The invention relates to a winding machine used in the manufacture of lithium battery core packs, in particular to a winding head mechanism. Background technique [0002] In the field of winding machines for making lithium battery core packs, in the prior art, the winding heads used by multi-station winding machines such as double-station or three-station evenly distribute each station in a cylindrical area ; The switching of each station is realized through the rotation of the cylindrical area, and the winding of each station also needs to be able to realize functions such as rotation and positioning independently. [0003] Under this scheme, during the station switching process, the drive system that realizes the rotation and positioning of each station will have related cables. If the drive system rotates following the station switch, the cables of each station will be knotted and broken. Case. In the prior art, multi-station winding motors usuall...
