Abstract
The utility model discloses a lug pruning device for a lithium ion battery, which comprises a rack, wherein the rack comprises a left support plate and a right support plate, a battery clamp slot is fixed on the left support plate, a horizontal cylinder is arranged on the right support plate, a piston rod of the horizontal cylinder faces towards the left and the end part of the horizontal cylinder is fixed with a battery clamp plate matched with the battery clamp slot; a horizontal baffle plate is arranged at the bottom of the batter clamp slot and a notch for placing a lug is arranged on the baffle plate; a lug clamp plate matched with the baffle plate is fixed at the bottom of the battery clamp plate; a vertical cylinder is arranged below the lug clamp plate on the rack, a piston rod of the vertical cylinder faces upwards, and a cutter is arranged at the end part of the vertical cylinder. According to the lug pruning device for the lithium ion battery, the lug can be pruned while the lug faces downwards and the battery is reversely arranged, metal chip generated during the lug pruning only falls down due to the action of gravity without falling in the middle of a battery core at the upper part, so that large self-discharge of the battery caused by the metal chip and even the safety problem can be effectively avoided, and the operation is simple and convenient.
Description
Technical field:
The utility model relates generally to the cell safety technical field, relates in particular to a kind of lithium ion cell polar ear clipping device.
Background technology:
Lithium rechargeable battery is as a kind of ideal source of environmental protection, because have high energy density, long cycle life and memory-less effect, special advantages such as pollution-free, makes it have broad application prospects.At present, lithium ion battery just progressively replaces the electrical source of power that fossil fuel energy and conventional batteries become multiple electronic device.Especially lithium ion battery causes showing great attention to of many researchers as the electrical source of power of electric automobile.
In the lithium ion battery manufacture process, before the welding of lug and bridge welding, because the superimposed thickness of lug is often than battery thin thickness, problem different in size appears in the superimposed back of lug, need prune neat.At present; The metal fillings that the existing equipment of pruning lug produces when all not considering to prune lug; These metal fillings are easy to fall into inside battery, and little metal fillings through after the redox reaction, is easy to deposit to and causes on the barrier film that self-discharge of battery is big when discharging and recharging; Big metal fillings then directly diaphragm cause battery short circuit, cause security incident.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of lithium ion cell polar ear clipping device to be provided, and it can prevent effectively that the lug chip from falling into battery inside, has improved battery safety, and simple, convenient.
The utility model is realized through following technical scheme:
A kind of lithium ion cell polar ear clipping device; It is characterized in that: include frame; Frame includes left and right gripper shoe; Be fixed with the battery draw-in groove on the said left gripper shoe, on the said right gripper shoe lateral cylinder be installed, the piston rod of lateral cylinder left and its end be fixed with the battery clamping plate that cooperate with the battery draw-in groove; The bottom of said battery draw-in groove is provided with horizontal baffle plate, and baffle plate is provided with the breach of placing lug; The bottom of said battery clamping plate is fixed with the lug clamping plate that cooperate with baffle plate; The below that is positioned at the lug clamping plate on the said frame is provided with vertical cylinder, and the piston rod of vertical cylinder makes progress and its end is equipped with cutting knife.
A kind of lithium ion cell polar ear clipping device is characterized in that: the piston rod end of said vertical cylinder is fixed with knife rest, and said knife rest is provided with right baffle-plate and right cylinder, the piston rod of said right cylinder left and its end be fixed with the cutting knife that cooperates with right baffle-plate.
Said battery draw-in groove and battery clamping plate are combined into the anchor clamps of self-contained battery, and said baffle plate and lug clamping plate are combined into the fixedly anchor clamps of lug, and said right baffle-plate and cutting knife constitute the cutter of pruning lug.
Start lateral cylinder, through the left and right move left and right that realizes battery baffle plate and lug baffle plate that moves of its piston rod.Equally, start vertical cylinder, realize moving up and down of cutting knife, satisfy lug thus and stay the different needs of long standard through moving up and down of its piston rod.
The utility model has the advantages that:
The utility model can realize pruning when the downward battery of lug is inverted lug; The metal fillings gravitate that produces when pruning lug only can drop downwards; And go in the middle of can not falling into top battery; Thereby effectively avoided because the self-discharge of battery that these metal fillings cause is big even safety problem, simple, convenient.
Description of drawings:
Fig. 1 is the front view of the utility model.
Fig. 2 is the structural representation of the utility model.
The specific embodiment:
Referring to accompanying drawing.
A kind of lithium ion cell polar ear clipping device; Include frame; Frame includes left and right gripper shoe 5,6; Be fixed with battery draw-in groove 1-1 on the said left gripper shoe 5, on the said right gripper shoe 6 lateral cylinder 4-1 be installed, the piston rod of lateral cylinder 4-1 left and its end be fixed with the battery clamping plate 1-2 that cooperates with battery draw-in groove 1-1; The bottom of said battery draw-in groove 1-1 is provided with horizontal baffle plate 7, and baffle plate 7 is provided with the breach 8 of placing lug; The bottom of said battery clamping plate 1-2 is fixed with the lug clamping plate 9 that cooperate with baffle plate 7; The below that is positioned at lug clamping plate 9 on the said frame is provided with vertical cylinder 4-3, and the piston rod of vertical cylinder 4-3 makes progress and its end is equipped with cutting knife 3-2.
The piston rod end of vertical cylinder 10 is fixed with knife rest, and said knife rest is provided with right baffle-plate 3-1 and right cylinder 4-2, the piston rod of said right cylinder 4-2 left and its end be fixed with the cutting knife 3-2 that cooperates with right baffle-plate 3-1.
The position of said breach 8 and size are consistent with the position and the lug width of lug.The size of battery draw-in groove 1-1 is consistent with the cell shapes of waiting to prune lug.Battery clamping plate 1-2 is mainly used in self-contained battery, is moved by lateral cylinder 4-1 control.Wherein battery draw-in groove 1-1 and battery clamping plate 1-2 can change according to battery size.
The cutter 3 of said pruning lug is made up of right baffle-plate 3-1 and cutting knife 3-2.The cutter 3 of said pruning lug can be regulated through cylinder 4-3 according to the length that the lug needs keep and move up and down.Cylinder 4-2 control cutting knife 3-2 move left and right, the lug cut-out that cutting knife 3-2 is cooperated with baffle plate 3-1 will stretch out reaches the purpose of pruning lug.
Said battery both can be the battery that adopts the multireel core to be formed in parallel, and also can be stacked battery.
