Description of reference numerals:Frame 101, pole piece material volume 102, cross roller 103, supporting plate 201, line rail 202, the first connector 203rd, supporting plate 204, cylinder 205, the second connector 206, pressure roller 207.
Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
Coordinate uses in the description of detailed description below:Using the vertical paper inward directions of Fig. 1 before, otherwise it is Afterwards.
Embodiment one:
As shown in figure 1, lug creasing mechanism described in the utility model includes frame 101, material volume is installed in frame 101 Axle, roller 103 and supporting plate 201 are crossed, material spool is rotatably installed in frame 101 with roller 103 is crossed, and supporting plate 201 is fixed on machine On frame 101, pole piece material volume 102 is installed in material spool, the roll surface for crossing roller 103 there are two kinds of materials, and front end majority is carbon fiber Material, rear end fraction are quality of rubber materials.One group of line rail 202 is mounted with supporting plate 201, is slided on line rail 202 by sliding block Coordinate supporting plate 204, supporting plate 204 is connected rectangular shape with the right-hand member of the first connector 203, and the left end of the first connector 203 passes through One fixable sliding part was through in the installation axle of roller 103, and the cylinder body of cylinder 205 is fixed on supporting plate 204, cylinder 205 Extension bar even be the second connector 206, what is installed in the second connector 206 is pressure roller 207, and the roll surface of pressure roller 207 has Dentation burr, Polyhedral point-like burr, linear burr or rounded ridge, can be pressed on the rubber roll surface on roller 103, rubber Roll surface plasticity is fine.
Linked together because the first connector 203 will cross roller 103 with the supporting plate 204 for being provided with pressure roller 207, so that mistake Roller 103 and pressure roller 207 can realize synchronizing moving, during pole piece unreels, can be adjusted according to the offset synchronous of lug The position of roller 103 and pressure roller 207, to realize correction.
In addition, it is described cross roller 103 and the unpowered input of pressure roller 207, it is necessary to ensured roller 103 and pressure roller 207 rotate it is smooth, The installation axle for crossing roller 103 and pressure roller 207 is installed using the less bearing of frictional force, such as edible vegetable oil bearing;Before the roller 103 excessively End is most of to be made using carbon fibre materials, and to mitigate the weight of roll body as far as possible, the rear end fraction for crossing roller 103 is rubber material Matter, it is good that pressure roller 207 was pressed in plasticity on the rubber roll surface of roller 103, and carbon fibre materials are not relatively pressure-resistant;The pressure roller 207 roll surface uses aluminium material.
The embodiment of lug creasing mechanism described in the utility model:As shown in figure 1, pole piece material volume 102 is arranged on Expect on axle, the distance between regulation pole piece material volume 102 and frame 101, after fixed, then the cunning by the left end of the first connector 203 Moving part adjusts the centering of rubber part of the pressure roller 207 with crossing roller 103.Upon power-up of the system, pole piece is released from material volume 102, warp When crossing roller 103, system control cylinder 205 stretches out so that the lug of pole piece side was pressed in the rubber on roller 103 by pressure roller 207 On rubber roll face, after such pole piece is released, crosses roller 103 and pressure roller 207 cooperates and rolled, wave is extruded on the lug of pole piece Shape impression.
Embodiment two:
When there is lug the both sides of pole piece, the both ends roll surface for crossing roller 103 is arranged to quality of rubber materials, middle roll surface is carbon Fiber Materials, the rubber roll surface at both ends contact with the lug of pole piece both sides, and middle carbon fiber roll surface contacts with pole piece;In supporting plate Two cylinders 205 are installed, two cylinders 205 are corresponding with the lug of pole piece both sides respectively, in stretching for two cylinders 205 on 204 The second connector 206 is connected on rod, pressure roller 207 is each installed on two the second connectors 206, two pressure rollers 207 are distinguished It is pressed on the lug of pole piece both sides, impression is extruded on lug, increases the intensity of lug.
Embodiment three:
Lug described in embodiment one or embodiment two is smoothed into the feed end that follower is arranged on lithium battery winder, Before pole piece is wound into lithium battery winder, impression is extruded on lug, to increase the intensity of lug so that lug with With pole piece can normal winding, avoid lug from bending.
