The present invention proposes a cutting device, mainly installed on a cell winding machine, for cutting a pole foil with a predetermined length, and the cell winding machine will be described as an example, and in the embodiment of the present invention, referring to fig. 1 and 2, a driver (not shown) of the cutting device 90 drives a rotation shaft 30 to rotate, so that the rotation shaft 30 periodically rotates. The first cam 21 of the clamping mechanism 20 is mounted on the rotating shaft 30, the first cam 21 has a first guide surface 211, and the input end of the first follower assembly 22 abuts against the first guide surface 211 to form a first intermittent motion mechanism. The first cam 21 serves as a driving member of the first intermittent mechanism to provide the first driven member 22 with an intermittent power output that coincides with the rotation period of the rotating shaft 30. The second cam 11 of the cutting mechanism 10 is mounted on the rotating shaft 30, the second cam 11 has a second guide surface 111, and the input end of the second follower assembly 12 abuts against the second guide surface 111 to form a second intermittent mechanism. The second cam 11 serves as a driving member of the second intermittent motion mechanism to provide the second driven member 12 with an intermittent power output that also coincides with the rotation period of the rotating shaft 30. Thereby the movement cycle of the clamping mechanism 20 and the cutting mechanism 10 is consistent, and the processing consistency of the polar foil in each cycle is improved. Moreover, when the cutter 13 cuts the polar foil each time, the polar foil is clamped under the action of the tractor 23 and is still, so that uneven stress caused by extra impact force in the process of cutting the polar foil is avoided, and the cutter 13 has more accurate cuts when cutting the polar foil each time. In addition, the movement track of the cutting mechanism 10 is formed by the second cam 11 under the guidance of the second guiding surface 111, the stroke of the second cam 11 for providing mechanical limit has stability, the stroke of the second driven component 12 for driving the cutter 13 to move is less in dispersion, the cutting position of the polar foil is easier to control, and the precision of the cell winding machine is improved.
Referring to fig. 1 and 2, in particular, the driver may be a motor, etc., and the input end of the first driven component 22 abuts against the first guide surface 211, and the first driven component 22 may be a transmission rod, or may be a link mechanism composed of a plurality of transmission rods, where the input end of the first driven component 22 may be one end of the transmission rod, or may be one of the transmission rods of the link mechanism. There may be various ways in which the input end of the first driven component 22 abuts against the first guide surface 211, for example, the input end of the first driven component 22 may directly abut against the first guide surface 211 to slide, or a first rolling wheel (not shown) may be disposed on one side of the input end of the first driven component 22, so that the input end of the first driven component 22 rolls on the first guide surface 211 through the first rolling wheel to reduce friction. In addition, a first elastic member (not shown) may be disposed at the input end of the first driven member 22 to maintain the input end of the first driven member 22 in close contact with the first guide surface 211, which will not be described in detail herein. Similarly, the input end of the second driven component 12 abuts against the second guide surface 111, and the second driven component 12 may be a transmission rod, or may be a link mechanism formed by a plurality of transmission rods, where the input end of the second driven component 12 may be one end of the transmission rod, or may be one of the transmission rods of the link mechanism. There may be various ways in which the input end of the second driven component 12 abuts against the second guide surface 111, for example, by directly abutting the input end thereof against the second guide surface 111 to slide, or a rolling wheel 124 may be disposed on the input end side of the second driven component 12, so that the input end of the second driven component 12 rolls on the second guide surface 111 through the rolling wheel 124 to reduce friction. In addition, a resilient member (not shown) may be provided at the input end of the second driven member 12 to maintain the input end of the second driven member 12 in close contact with the second guide surface 111, which will not be described in detail herein.
Referring to fig. 1, 2, 3 and 4, the first cam 21 drives the first driven component 22 to reciprocate through the first guiding surface 211, and the output end of the first driven component 22 is connected to the tractor 23, where the connection may be a fixed connection or a movable connection, etc., so as to drive the tractor 23 to alternately form a conveying state and an idle state in one rotation period of the rotating shaft 30. When the retractor 23 is in the conveying state, the retractor 23 conveys a prescribed length of the pole foil in the feeding direction; when the retractor 23 is in the rest state, the retractor 23 clamps the pole foil at two spaced apart positions in the feeding direction, so that the pole foil is in the rest state. It should be specifically noted that, when the retractor 23 is in the idle state, the first guiding surface 211 corresponding to the first cam 21 may be a plane surface or a curved surface, and when the position is a curved surface, the change of the curvature does not affect the clamping force of the retractor 23 to clamp the polar foil, so that the polar foil is in the static state, and the clamping force of the retractor 23 may be changed, which will not be described in detail herein. The second guiding surface 111 has a displacement section 111a corresponding to the idle state of the tractor 23, when the tractor 23 is in the idle state, the displacement section 111a of the second guiding surface 111 is used for driving the second driven component 12 to reciprocate, and the output end of the second driven component 12 is connected with the cutter 13, where the connection manner may be fixed connection or movable connection, etc., so that the cutter 13 is driven by the second driven component 12 to alternately have an extended state and a retracted state. When the input end of the second driven component 12 is located at the displacement section 111a of the second guiding surface 111, the cutter 13 switches between the extended state and the retracted state, so that the cutter 13 cuts off the polar foil between two spaced positions, and during the process of cutting off the polar foil, a cutter holder (not shown) may be disposed at a position corresponding to the cutter 13, or a notch may be formed by disposing a movable cutter holder and cutting off the polar foil in cooperation with the cutter 13, which will not be described in detail herein. The polar foil on one side of the notch is conveyed to the next station, and the polar foil on the other side of the notch is conveyed for a specified length along the feeding direction after being clamped by the tractor 23, and then is clamped again by the tractor 23, so that a person skilled in the art can obtain a corresponding technical scheme through the embodiment or the attached drawings of the invention, and details are not repeated here.
With continued reference to fig. 1, 2, 3 and 4, it is preferred that the first guide surface 211 has a planar section 211a and that the retractor 23 is in a resting state when the input end of the first driven assembly 22 is positioned in the planar section 211a, the purpose of this being to allow the clamping force of the retractor 23 to remain constant while the retractor 23 is clamping the pole foil and while the pole foil is stationary, thereby reducing the additional impact force caused by the change in clamping force of the retractor 23. In addition, the planar segment 211a is easier to manufacture than the curved segment. Preferably, the displacement section 111a of the second guiding surface 111 forms a plane angle with the rotation shaft 30 as a rotation center, which is smaller than the plane angle formed by the plane section 211a of the first guiding surface 211 with the rotation shaft 30 as a rotation center. The plane angle as referred to herein is a plane angle formed in two planes parallel to each other or in the same plane. Of course, the plane angle formed by the displacement section 111a of the second guide surface 111 with the rotation axis 30 as the rotation center may be equal to the plane angle formed by the plane section 211a of the first guide surface 211 with the rotation axis 30 as the rotation center. The displacement section 111a of the second guide surface 111 takes the rotating shaft 30 as the rotation center to form a plane angle which is smaller than the plane angle formed by the plane section 211a of the first guide surface 211 taking the rotating shaft 30 as the rotation center, so that the position error of the first cam 21 and/or the second cam 11 formed in the circumferential direction of the rotating shaft 30 due to mechanical abrasion is avoided, redundancy is provided for coaxial installation of the first cam 21 and the second cam 11, and the cutter 13 can be completely in a static state that the polar foil is clamped when switching between an extending state and a retracting state, and the precision of the cell winder is further improved.

The advantage of this arrangement is that the cutting blade 13 can be kept in a consistent cutting action when cutting the pole foil, which improves the quality of the cut.
