In order to be more clearly understood the cutting mould method for correcting error of the application, with cutting mould to successively in the present embodiment
Multiple pole pieces of connection are cut respectively, are illustrated for the multiple single pole pieces of formation, that is, be to cutting material piece
Pole piece needs to be cut according to the offset of pole piece adjustment during cutting mould cuts sequentially connected multiple pole pieces
Die location.Certainly, a kind of cutting mould method for correcting error of the application, be applicable not only to enumerate in the present embodiment is sequentially connected
Multiple pole pieces cutting, be equally applicable to cut similar to the unclassified stores of pole piece, the application not cutting with pole piece
It is limited.
In the present embodiment, when battery core is stacked by 30 pole pieces, before battery core stacking, formed by multiple pole pieces
Material volume is sent by conveying and cuts station to cutting mould and cut, and to form single pole piece, is formed convenient for subsequent stackings
Battery core.Under present circumstances, during material volume conveys, the material volume formed using 30 pole pieces is a cycle, it will usually the 23rd
Form camber between a pole piece and the 24th pole piece, thus after completing the cutting of the 23rd pole piece, need to cutting mould into
Row correction, the 24th pole piece to the 30th pole piece and in the latter period, cut out to the 23rd pole piece according to this by first pole piece
It is cut position after cutting mold correction.Therefore, in this example, P=30, M=23, N=7.
In this example, cutting mould method for correcting error specifically, default 30 sequentially connect is a cycle to cutting material piece
And preset reference information, wherein when preset reference information, according to the original state preset reference information of cutting mould, cutting mould
Original state, refer to that the initial position of cutting mould, reference information refer to that starting sheet is transported to initial position originally
When cutting station of cutting mould, first starting sheet shift in OK range, can guarantee hanging down for starting sheet at the beginning of after cutting off
Straight degree within the limits prescribed, at this point, with the location information of first starting sheet be according to one reference information of setting, such as can be with
The location information of first starting sheet is benchmark information, i.e., using every pole piece side of first starting sheet as reference, alternatively, according to cutting mould
Original state, obtain just starting sheet location information after, according to the location information of first starting sheet preset a reference line, benchmark
Line is parallel to a wherein pole piece side for first starting sheet.
Material volume conveying is initial, and for a cycle, what 30 pole pieces can sequentially be delivered to cutting mould cuts work
Position, CCD obtains location information of each pole piece relative to reference information, and at least stores the 24th pole piece of acquisition to the 30th
Location information of a pole piece relative to reference information.24th pole piece is to the 30th location information of the pole piece relative to reference information
Can be it is a variety of, for example, it may be the 24th pole piece is to the location information sequentially position relative to first starting sheet of the 30th pole piece
Confidence breath deviation angle, also or for the 24th pole piece to the 30th pole piece location information sequentially relative to the inclined of reference line
Move angle.Namely in a cycle, cutting mould does not generate the movement of correction, and a cycle can generate the 24th pole piece
To the deviation angle of the 30th pole piece totally 7 pole pieces, and it is inclined to the 30th pole piece totally 7 pole pieces at least to store the 24th pole piece
Move angle.It when being stored to the deviation angle of the pole piece of CCD detection, is handled using stacked manner, setting length is greater than or waits
In 80, it is that the data in storehouse array correspond to the feedback order of pointer response data, finally using the purpose that storehouse is handled
One data are the data of last time storage, in a cycle, when being stored in the deviation angle of at least seven pole piece, most
At least seven data are the data of newest deposit afterwards.
Then enter in second period, the 1st pole piece to the 23rd pole piece in second period is orderly sent to sanction
Cutting position, CCD obtain the deviation angle of the 1st pole piece to the 23rd pole piece each of totally 23 pole pieces pole piece respectively, and
The deviation angle for storing 23 pole pieces, from the offset of 23 pole pieces in second period and 7 pole pieces in a cycle
In angle, the deviation angle of 20 pole pieces is chosen, angular average α is sought to the deviation angle of 20 pole pieces, it is flat according to angle
Mean value α rectifies a deviation to cutting mould.Specifically, according to angular average α be calculated correction driving portion linear drives away from
From L, linear drives distance L can be obtained according to formula L=TAN α × R, and R is cutting mould radius of turn, when correction driving portion
When generating linear drives distance L, correction driving portion driving cutting mould rotates angular average α, completes in second period
The correction of mold.After completing correction, the 24th pole piece is orderly sent to the 30th pole piece and cuts station, and CCD successively obtains the
The deviation angle of 24 pole pieces each pole piece into the 30th pole piece, and the 24th pole piece is stored to the 30th pole piece totally 7
The deviation angle of pole piece.When entering second period, the data finally stored in storehouse array are the deviation angle of 7 pole pieces
Degree.
Then enter in the third period, the 1st pole piece to the 23rd pole piece in the third period is orderly sent to sanction
Cutting position, CCD obtain the deviation angle of the 1st pole piece to the 23rd pole piece each of totally 23 pole pieces pole piece respectively, and
The deviation angle for storing 23 pole pieces, from the offset of 23 pole pieces in the third period and 7 pole pieces in second period
In angle, the deviation angle of 20 pole pieces is chosen, angular average α is sought to the deviation angle of 20 pole pieces, it is flat according to angle
Mean value α rectifies a deviation to cutting mould.Specifically, according to angular average α be calculated correction driving portion linear drives away from
From L, when driving portion of rectifying a deviation generates linear drives distance L, correction driving portion driving cutting mould rotates angular average α, complete
At the correction of the mold in the third period.After completing correction, the 24th pole piece in the third period to the 30th pole piece according to
Sequence, which is sent to, cuts station, and CCD successively obtains the deviation angle of the 24th pole piece each pole piece into the 30th pole piece, and deposits
Store up the deviation angle of the 24th pole piece to the 30th pole piece totally 7 pole pieces.When entering the third period, finally deposited in storehouse array
The data put are the deviation angle of 7 pole pieces.Repeatedly, entangling for cutting mould in each subsequent period can be completed
Partially.
In this example, second period is into each subsequent period, such as the position of last 7 pole pieces in second period
The location information that the location information of confidence breath and preceding 23 pole pieces in the period 3 obtains after once rectifying a deviation for cutting mould is same,
Therefore, by the location information of this 30 pole pieces, the movement tendency of material volume between the adjacent movement of correction twice out can be fed back, is led to
The deviation angle for crossing a certain number of pole pieces in 30 pole pieces of analysis, may further determine that the correction of cutting mould next time
Movement.
