33, sliding block and the knife rest 4 of the cross slide way slide block component 33 connect firmly, and linear motor drives knife rest along cross slide way slide block group
Guide rail in part does translational sideways movement.
In the present embodiment, driving motor 26 drives the rotational velocity of disc cutter 5 and linear motor 32 that knife rest 4 is driven to translate
Speed sync, this control mode not having bad friction between disc cutter and straight sword cutter during cutting,
Additional tool wear will not be generated, and entirely cuts the shearing that process is a point.
It further include being provided with cleaning vacuum plant in the present embodiment, to draw the dust for cutting and generating in the process.
Pole piece of power battery width has the tendency that increasing often in 300mm with up to 800mm.It is automating
During preparing pole piece, traditional straight knife cut mode requires edge plane degree and cutting edge straightness very high, can just have good
Cut effect；Processing technology and assembly technology are required high；Meanwhile the vibration and impact generated in blanking process is difficult to
It eliminates, the control and stability to equipment generate adverse effect；And due to lithium battery positive and negative pole material characteristic, positive and negative anodes
Cutter mold can not be general, eventually leads to that this mode is at high cost, and structure is complicated；Maintainability is poor and automates difficulty of changing the line of production.And
The present invention, which uses disc cutter and straight sword cutter cooperation high speed to cut, to be had as follows a little: (1) due to disc cutter size itself
It is small and small with straight sword cutter coordinate contact surface product, to reduce infrastructure cost about 40%, and significantly reduces machining accuracy and want
It asks and assembly precision requirement；(2) small, ride comfort is impacted with the shear action completed with straight sword cutter from disc cutter rotation
It is good, it is greatly improved the service life of cutter；(3) it due to the cut-in angle of disc cutter and straight sword cutter is big, and mentions
High cutting quality, effective control of burr.
And by modularized design, Different Industries such as photovoltaic industry as allowing the present invention to apply to associated class is real
Now high speed, efficiently produce new construction.Cutting edge cutter is replaced on maintainability can achieve the effect that quickly repairs a die, and can accomplish
It is unified that mold manufactures upper positive and negative anodes cutting mould.
Specific implementation process: original state lower disc cutter 5 is parked in one end of straight sword cutter 2, the cutting edge of disc cutter 5 with
The cutting edge of straight sword cutter 2 is mutually engaged；When pole piece send fixed length to reach cutting position, the driving motor 26 on knife rest 4 drives disk to cut
5 rotation of knife, while linear motor 32 drives knife rest 4 to start translational motion from left to right, the rotational velocity and knife rest of disc cutter 5
4 movement speed is synchronous；In 4 moving process of knife rest, Cam Follower 22 is first along the lifting inclined-plane 23 of 12 left end of material-pressing rack
It rolls, since material-pressing rack 12 can vertically be gone up and down, therefore Cam Follower 22 can push material-pressing rack 12 to move down, so that preceding,
Afterwards the pressure plate 13 of two sides downwards with cutting knife mounting seat 9(or push type broach seat 8) cooperation pushes down the both ends of pole piece, when avoiding subsequent rolling cut
Pole piece positioning；Cam Follower 22 is rolled along pressure maintaining horizontal plane 24 later, and the position of material-pressing rack 12 remains stationary at this time, disk
Cutter 5 and flexible binder disk 27 are in contact with pole piece, and flexible binder disk 27 pushes down pole piece, and disc cutter 5 cuts off pole piece；
Last Cam Follower 22 is rolled along with the lifting inclined-plane 23 of 12 right end of material-pressing rack, elastic force of the material-pressing rack 12 in reset spring 16
It is moved upward to initial position under effect, completes the cutting of pole piece.After linear motor 32 drives disc cutter 5 quickly to cut,
The right end of straight sword cutter 2 is stopped at, when next circulation starts, disc cutter 5 is turned left from the right side cuts pole piece.
The another technical solution that the present invention uses is: a kind of work side of lithium ion power cell pole flakes fly-cutting mechanism
