In the flaw labeling device of the embodiment according to Fig. 1, the sticking position of the labelling label adjacent with flaw labeling unit 130 can set after otch (slitting) operation on electrode material 10, and the attaching of labelling label can perform in the downstream of the cutting machine 170 performing incision operation. Incision operation refers to wherein be divided into by the wide width of electrode material 10 on the width Z2 be perpendicular to the direction of the supply Z1 cutting operation of little width, and electrode material 10 can be divided into suitable width as desired. Such as, the Dan Shu of the electrode material 10 entered from the upstream of cutting machine 170 is divided into three beams 10a, 10b and 10c when through two cutting machines 170.
Such as, in the downstream of cutting machine 170, divided bundle 10a, 10b and 10c can advance to the position offset with one another, namely Z2 can advance to relatively high position at the first material 10a of central part office in the width direction, and Z2 can advance to relatively low position at the second material 10b and the three material 10c of side portion in the width direction. For the first material 10a and second and third material 10b and 10c separated in space, upper and lower side, first flaw labeling unit 130a and the second flaw labeling unit 130b can be arranged apart, and the first flaw labeling unit 130a in upside can perform label on the first material 10a advance to relatively high position and attach, the second flaw labeling unit 130b in downside can perform label on the second material 10b and the three material 10c advance to relatively low position and attach.
Owing to the sticking position of labelling label sets after the incision operation of segmentation electrode material 10, so when performing cutting operation to remove defect area, it is possible to reduce the electrode material 10 that is dropped also prevents the wasting of resources.
In the flaw labeling device of the embodiment according to Fig. 1, the feed speed of electrode material 10 progressively changed according to the stage, thus the attaching of smoothly execution flag label on the defect area detected. The feed speed of electrode material 10 can regulate according to the intervention of controller 118 and from the instruction of integrating control unit 150.
Fig. 3 illustrates curve chart, and it shows the feed speed change according to the state of the art of flaw labeling device. With reference to Fig. 3, on electrode material 10, do not detect that, in the first stage P1 of defect, electrode material 10 provides with First Speed V1 wherein. First Speed V1 can be set to the relatively fast speed in whole inspection technique, it is possible to is maintained until and defect detected. At first stage P1, promptly perform technique by being maintained at the inspection technique of constant speed.
The second stage P2 of defect area is detected wherein by defect detection unit 120, obtain the information about detection defect area at integrating control unit 150, then the feed speed of electrode material 10 is changed into the second speed V2 slower than First Speed V1 from quick First Speed V1. Such as, LS retardation of the feed speed for reducing electrode material 10 is operated so that when defect area is close to the sticking position of labelling label, and the feed speed of electrode material 10 progressively changes from fast state to the state at a slow speed attaching labelling label.
The point that defect area is detected corresponding to for reduce feed speed retardation LS beginning, after extra rate conversion, second speed V2 can be adjusted to the third speed V3 slower than second speed V2. Retardation, LS terminated at the some place terminated that attaches of labelling label.
At second stage P2, integrating control unit 150 can obtain the position of defect area, it is possible to by using controller 118 to drive flaw labeling unit 130, it is possible to the mobile initiation command being used for moving labelling machine 135 is sent to the position of defect area. Such as, the position of the defect area on width Z2 can be passed through integrating control unit 150 and be imported into controller 138, when the position of defect area is set to target location, labelling machine 135 can be moved to target location, and labelling machine 135 can remain stationary as until defect area is provided to the sticking position of labelling label along direction of the supply Z1.
Defect area is provided to the phase III P3 of the sticking position of labelling label along direction of the supply Z1 wherein, and the feed speed of electrode material 10 is converted into the third speed V3 being slower than second speed V2. Such as, when defect area arrives the sticking position of labelling label, phase III P3 can start (initiate), and when labelling label is attached on defect area, phase III P3 can terminate. Here, labelling label is attached on defect area by the labelling machine 135 of the position being maintained at defect area.
Alternately, when defect area is along direction of the supply Z1 close to the sticking position of labelling label, phase III P3 can start before defect area arrives sticking position, it is possible to terminates after labelling label is attached on defect area.
The fourth stage P4 attaching end of labelling label wherein, the transfer rate of electrode material 10 returns to quick First Speed V1 from third speed V3. In another embodiment, it is possible to setting third speed V3 accelerates to and the acceleration of First Speed V1 rate conversion can progressively be performed.
After being cut into the unit of preliminary dimension via the electrode material 10 that continuously stream provides and being formed as independent battery lead plate, plug dividing plate by the stacking battery lead plate (positive electrode plate and negative electrode plate) with opposed polarity of order betwixt and form electrode assemblie simultaneously.

Integrating control unit 150 operates retardation, and within this retardation, feed speed arrives the front reduction gear of the sticking position of labelling label at defect area so that the attaching of labelling label can smoothly perform.
Such as, integrating control unit 150 can obtain the positional information relevant to defect area, it is possible to drives the labelling machine 135 attaching labelling label. Namely, integrating control unit 150 can by the position coordinates in familiar lacunas region with by the position of defect area being set as, target area drives labelling machine 135 on the width Z2 of electrode material 10 so that labelling machine 135 can be made to remain stationary as integrating control unit 150 until defect area arrives the sticking position of labelling label.
Afterwards, when determining sticking position (the operation S40) that defect area arrives labelling label, integrating control unit 150 performs the second deceleration, in slowing down second, the feed speed of electrode material 10 is converted to the third speed V3 (operation S50) being slower than second speed V2 from second speed V2. By gradually reducing the transfer rate of electrode material 10 with the first deceleration (operation S30) and the second deceleration (operation S50), integrating control unit 150 can allow the attaching of labelling label smoothly to be performed.
Afterwards, integrating control unit 150 drives flaw labeling unit 130 so that labelling label is attached on defect area (operation S60).
When the attaching of the labelling label relevant to defect area completes, the feed speed of electrode material 10 is returned to quick First Speed V1 (operation S70) from slow third speed V3 by integrating control unit 150. Here, integrating control unit 150 can operate acceleration, and within this acceleration, the feed speed of electrode material 10 progressively accelerates to fast First Speed V1 from slow third speed V3.
