Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
The front view of upper slitter in a kind of new type lithium ion battery pole piece trimming cutter that Fig. 1 provides for the utility model, the rearview of upper slitter in a kind of new type lithium ion battery pole piece trimming cutter that Fig. 2 provides for the utility model, the left view of upper slitter in a kind of new type lithium ion battery pole piece trimming cutter that Fig. 3 provides for the utility model, the vertical view of cutter down in a kind of new type lithium ion battery pole piece trimming cutter that the front view of cutter down in a kind of new type lithium ion battery pole piece trimming cutter that Fig. 4 provides for the utility model, Fig. 5 provide for the utility model.
Referring to Fig. 1 to Fig. 5, the utility model provides a kind of new type lithium ion battery pole piece trimming cutter, and this cutter includes upper slitter 1 and following cutter 2, and described upper slitter 1 is positioned at the described top of cutter 2 down;
In the utility model, described upper slitter 1 can be installed on the panel that can slide up and down that has slide block, and described cutter 2 down can be installed on the immovable support;
Be specially: two ends, two ends, the left and right sides, described upper slitter 1 top are installed on the panel that can slide up and down that has slide block with a screw respectively, and described two ends, cutter 2 left and right sides down are installed on the immovable support with two screws respectively;
Referring to shown in Figure 4, the described top of cutter 2 down is provided with and cuts groove 3, described shape, the size and the shape of described upper slitter 1, big or small corresponding coupling that cuts groove 3, when cutting battery pole piece, upper slitter 1 moves down, engaged with following cutter 2, thereby to cutting through the battery pole piece that cuts groove 3.
Need to prove, because battery pole piece cutting effect is good with bad, the degree of wear that depends on cutting tool fully, burr on the pole piece that the cutting of general new cutter institute forms is very little, therefore by reducing the degree of wear of cutting tool effectively, can significantly reduce the burr on the pole piece, the generation of Burr Problem on the control pole piece, burr on the pole piece is dropped to minimum value, thereby make the security performance that can not have influence on battery.
Therefore, in the utility model, the position that described upper slitter 1 and following cutter 2 are in contact with one another friction is provided with hard metal tip 4, be specially: described upper slitter 1 and following cutter 2 fixedly are inlaid with hard metal tip 4 on the cutting edge position, described upper slitter 1 and following cutter 2 also fixedly are inlaid with hard metal tip 4 on the non-blade port position, thereby can keep the friction balance so that upper slitter 1 and following cutter 2 are in contact with one another the position (comprising cutting edge position and non-blade port position) of friction, reach the effect of mutual minimal wear, reduce the wearing and tearing of cutter on the whole, and then reduce burr on the battery pole piece effectively, the generation of Burr Problem drops to minimum value with the burr on the pole piece on the control pole piece.
On the specific implementation, the bottom of described upper slitter 1 (being the cutting edge position) fixedly is inlaid with hard metal tip 4, and the back side at two ends, described upper slitter 1 left and right sides (being the non-blade port position) also fixedly is inlaid with hard metal tip 4; What be positioned at described following cutter 2 tops cuts groove 3 bottoms for descending the cutting edge of cutter 2, and the described bottom that cuts groove 3 fixedly is inlaid with hard metal tip 4, and the described left and right sides (being the non-blade port position) that cuts groove 3 fixedly is inlaid with hard metal tip 4.
For the utility model, when cutting battery pole piece, following cutter 2 is fixed, upper slitter 2 can slide up and down, being positioned at down, upper slitter 1 downward cutter 2 places of cutter 2 tops move, with engaged with following cutter 2, the battery pole piece that cutter 2 tops under the process is cut groove 3 cuts, because described upper slitter 1 and following cutter 2 are provided with hard metal tip being in contact with one another on the position of friction, therefore can be so that when battery pole piece be cut, the friction balance between upper slitter 1 and the following cutter 2 reaches the effect of mutual minimal wear, the final burr that cuts on the battery pole piece of back that reduces effectively, it is effective to make battery pole piece cut.
In sum, the technical scheme that is provided by above the utility model as seen, the utility model provides a kind of new type lithium ion battery pole piece trimming cutter, it can realize the balance that rubs, reduce the abrasive action between upper slitter and the following cutter effectively, the generation of Burr Problem drops to minimum value with the burr on the pole piece on the control pole piece, guarantee the safe handling of battery, be of great practical significance.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
