Description
Technical field
The utility model relates to a kind of blanking units, relates in particular to a kind of lithium band blanking units.The utility model also relates to a kind of button lithium battery negative pole automatic assembly line that comprises this blanking units.
Background technology
At present, button cell manufacturer is when producing the negative pole of button lithium battery, a kind of method is to adopt the circular lithium sheet that is die-cut into specified diameter in advance as negative material, put into the manual negative electrode casing that welds negative pole currect collecting net, with process for stamping the lithium sheet is pressed into currect collecting net again and combines with negative electrode casing.Owing to adopt manual operations, product quality is difficult to guarantee.And efficient is low, the cost height.Can't carry out large-scale production.
Second kind of processing method is to adopt machining, with lithium band the be die-cut into side sheet of punch press with weight feed, puts into negative electrode casing, through mechanical stamping the die forging of the square lithium sheet of negative pole become disk again, and is closely linked with negative electrode casing, forms one.Machining is saved the operation of artificial weldering negative pole currect collecting net, compares with manual operations, and production efficiency has had large increase.In this kind processing method, after the punch die cutting edge was sheared about the lithium band quilt, the lithium band can lose restriction in moment, because of the effect of lithium band internal stress, compressed under the restriction state in no clamping, nothing, can produce retraction, go here and there and move, and influenced the stability of feed length.
The utility model content
The purpose of this utility model provides a kind of button lithium battery negative pole automatic assembly line that can improve the lithium band blanking units of lithium band feed length stability and comprise this blanking units just in order to overcome above-mentioned deficiency of the prior art.
First technical scheme of the present utility model is: a kind of lithium band blanking units, comprise die cutting die and last shearing die head down, affixed lithium band pressing plate on the following die cutting die, the upper surface of following die cutting die is provided with to recessed lithium band and carries guide groove, carry guide groove that lithium tape input mouth and delivery outlet are set, the top of described lithium band delivery outlet is equipped with described going up and shears die head, and the described die-cut face of die cutting die down is provided with chamfering, and the degree of depth h of described chamfering carries the degree of depth of guide groove greater than the lithium band.
The angle [alpha] of described chamfering is that 30 degree are to 60 degree.
The angle [alpha] of described chamfering is 45 degree.
It is 0.5～1.5mm that the degree of depth h of described chamfering carries the value of channel depths greater than the lithium band.
Second technical scheme of the present utility model is: a kind of button lithium battery negative pole automatic assembly line comprises aforesaid lithium band blanking units.
The beneficial effects of the utility model are: owing to adopting die-cut at following die cutting die chamfering is set, the degree of depth h of chamfering carries the structure of the degree of depth of guide groove greater than the lithium band, the lithium band can produce distortion at die-cut follower head and form little downward protruding stupefied under the stress effect, catch on down die cutting die, make lithium band location, can't bounce back, thereby guarantee that the each feed length of lithium band is accurate.Prevent that effectively the lithium band is moving at die-cut back retraction, string, guarantee that the lithium belt end is in a fixed position.Guarantee that each feed lithium strip length is even.Need not increase anti-cam mechanism, simple and easy to do.
