Abstract

The invention discloses a reeling machine which comprises a rack assembly, an unreeling mechanism, a reeling mechanism, a feeding mechanism, a rubberizing device and a tension control mechanism, wherein the tension control mechanism comprises a pole piece deviation correcting device and a driving device which are arranged between the unreeling mechanism and the reeling mechanism; a reeling needle of the reeling mechanism performs a cam motion; the driving device is used for driving a pole piece to be synchronous with the traction of the reeling needle performing the cam motion to the pole piece and simultaneously preventing the unreeling of the pole piece and an deviation correcting operation from influencing the tension of the pole piece. According to the reeling machine, the stable tension control is effectively realized.

Description

technical field [0001] The invention relates to battery cell production equipment, in particular to a winding machine. Background technique [0002] In winding equipment, the control of tension has always been an important part, and the control of tension has a significant impact on the work of the winding device. Chinese patent application 201210446469.9 provides a winding machine, which is fixed by a tension roller, and the two tension rollers opposite to it are movable, and the pole piece passes through the three tension rollers in an S shape, driving the two tension rollers opposite to it to move , to tension or loosen the pole piece to control the tension of the pole piece, but this method is not smooth enough to control the tension. Contents of the invention [0003] In order to solve the above problems and realize stable tension control, the present invention provides a winding machine, including a frame assembly, an unwinding mechanism, a winding mechanism, a blan...
