Embodiment
Referring to Fig. 1 to Fig. 4, present pre-ferred embodiments are further elaborated.
A kind of lithium ion cell polar ear bending device, being mainly concerned with part has 1, two pair of bending mechanism 2 of pressing plate, pressing plate 1
It is primarily used to push down battery 8, bending mechanism 2 there are two groups, is separately mounted on two bending stations, and direction is conversely to pacify
When dress, i.e. battery 8 pass through bending station successively, anode ear, negative electrode lug are independently bent successively by two bending mechanisms 2.
Pressing plate 1 includes plate body 11, pinch roller 12, connecting rod 13.Pinch roller 12, which is fixed under plate body 11, to be shown, one in the present embodiment
Two groups are shared, every group of pressure consolidates a battery 8, there are two pinch rollers 12 at least on every group.The axis direction and battery 8 of pinch roller 12 simultaneously
Axis direction on the contrary, therefore the surface of pinch roller 12 may be designed to the periphery of battery 8 match arc.Connecting rod 13 is mainly outer
Power is connect, drives the raising and lowering of plate body 11.
What bending mechanism 2 was mainly concerned with has fixed part 21 and kink 22.Fixed part 21 is can to form stable axle
To support force, kink 22 is mainly bent to lug part.
Fixed part 21 includes fixed block 211 and drives the motor 212 of fixed block.Fixed block 211 can just withstand on battery
End, motor 212 can drive axis direction of the fixed block 211 along battery 8 to move back and forth.
Kink 212 includes two pieces of movable blocks 3, push rod 4, driving lever 5.Two pieces of movable blocks 3 are respectively positioned at battery pole ear 81
Both sides, after movable block 3 is driven effect, reciprocating in opposite direction.I.e. 3 relative motion of movable block when, clamp lug 81,
During reverse motions, lug 81 is unclamped.Unclamped immediately after two pieces of movable blocks 3 clamping lug 81 driven, form floating holder to electricity
Finely tuned centered on lug 81 in pond.
Push rod 4 includes the body of rod 41, termination 42, and the body of rod 41 mainly connects driving, drives termination 42 axially to be transported along battery 8
It is dynamic.Curved shape structure, centre form one and are just stuck in battery center among termination 42, play the salient point 43 of positioning, hold
First 42 top is outwardly formed a claw 44 simultaneously, can just clasp the edge of battery 8.
The Position Design of driving lever 5 in the lower section of lug, global shape as an inverted L-shaped rod member, and be can be around L
The turning point of shape rotates.The vertical portion 51 of L-shaped is a force application location, is exerted a force from outside to inside, then the horizontal part 52 of L-shaped is just upward
Tilt.The end of horizontal part 52 forms an overhead kick 53, and overhead kick 53 is contradicted on the madial wall of lug 81.When horizontal part 52 to
During upper tilting, overhead kick 53 just lifts lug 81, can complete bending action.
At work, bending technique is mainly as follows by the present invention：
Two bending stations of design, independently bend battery plus-negative plate ear on the streamline of lithium ion battery production,
Battery 8 is transported to first bending station, and lug bending is carried out to the one end of battery 8, and second bending station is transported to after bending,
Lug bending is carried out to the other end of battery 8.Because streamline is all to use to work continuously, therefore can be to two stations while work
Make, completely without influence pipelining speed.
Declined first by pressing plate 1, it is spacing together to two batteries 8, so installed in the opposite direction on latter two bending station
Bending mechanism does bending step simultaneously to two batteries 8；After bending, pressing plate 1 gos up, and is bent originally at first on station
Battery 8 go to second bending station on continue to bend other end lug, and first to be available bending station
Filled up by next battery 8, and then have already passed through in second battery 8 bent on station and bend twice originally, by streamline
Take bending station out of.
The bending step of wherein each station includes：The first step, the floating holder of kink, it is movable block in the present embodiment
3 actions for loosening lug by clamping are finely tuned to the circumferential locations of motor 8.Second step, push rod 4 withstand the bending pole of battery 8
One end of ear.3rd step, the fixed block 211 of fixed part 21 have the driving of motor 212 to stretch out, support the other end of battery.4th
Step, driving lever 5 are stirred, and bend lug 81.5th step, fixed block 211, bar top 4 and driving lever 5 remove power successively.
Above is the preferred embodiment for the present invention, some other are made under the premise of present inventive concept and simply replaces and changes
It is dynamic, it should all be considered as belonging to the protection category of the present invention.
