Description
Technical field
A kind of full lug lithium battery pole and lug method and device are the utility model is related to, belongs to lithium battery technology neck
Domain.
Background technology
At present since lithium battery has the advantages that high energy density, power density height, recycling often, in intelligent hand
It is widely used in the equipment such as machine, wearable device, electric bicycle and new-energy automobile, becomes and solve energy crisis and ring
The key of the global problems such as border pollution.Increasingly perfect with electric vehicle engineering, electric automobile and hybrid electric vehicle are from people
Daily life it is more and more nearer, the capacity, performance requirement to battery are higher and higher.Existing lithium battery uses multi pole ears knot more
Structure, the welding of lug use the welding manners such as supersonic welding, electric resistance welding, and the welding of lug is the important procedure of lithium battery,
If the internal resistance of the defects of generation lug comes off, rosin joint battery will greatly increase, caloric value can also increase, and patent of the present invention is adopted
With agitating friction weldering soldering polar ear, but the heat of welding process can have an impact the active material of core, can also influence electricity
The performance in pond.
Utility model content
The utility model aim is to provide a kind of new welding method and device, prevented lug come off, rosin joint etc.
Phenomenon, while influence of the heat to core active material in welding process is avoided, improve the performance of battery.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of welder of lug lithium battery pole and lug, including：Clamping device, for clamping core, to complete
Fixation to core；Positioner, for fixing pole and lug, which is specially：Positioner is divided into left positioning strip, the right side
Positioning strip, is pole and lug between two；Respectively there are a lug in the both sides of pole, and the contact outside connection strap of lug is left
Positioning strip, right positioning strip compress connection strap, and connection strap, lug, pole can be fixed together；Welder, sets stir thereon
Head is mixed, stirring-head can be moved along welding track；The left positioning strip or/and right positioning strip of positioner are equipped with groove, and groove is opened
Mouth direction forms ventilating duct, the inlet end connection blowing device of ventilating duct, ventilation in face of connection strap and by the stop of connection strap
Road, which can circulate, dries the gas of cooling.
The gas of ventilating duct is inertia compressed gas or nitrogen.
Direction of ventilation in ventilating duct is consistent with the moving direction of stirring-head.
Relative to the prior art, the utility model is designed with air cooling equipment, it is reduced while cooling and is steamed with oxygen gas and water
The contact of gas, reduces the influence to lug.
Brief description of the drawings
Fig. 1 is the application state schematic diagram of utility model.
Fig. 2 is the left view schematic diagram of Fig. 1.
Fig. 3 is lug lithium battery pole and preassembled schematic diagram before tab welding.
Embodiment
As illustrated in the accompanying drawings from 1 to 3, a kind of welder of lug lithium battery pole and lug, including：
Clamping device 1, for clamping core 2, to complete the fixation to core 2；
Positioner 3, for fixing pole and lug, which is specially：Positioner 3 divides to be determined for left positioning strip, the right side
Position bar, is pole 14 and lug 12 between two；Respectively there are a lug 12 in the both sides of pole 14, and the contact outside of lug 12 connects
Narrow bars 13, left positioning strip, right positioning strip compress connection strap 13, connection strap 13, lug 12, pole 14 can be fixed together；
Welder 4, sets stirring-head 5 thereon, and stirring-head 5 can be moved along welding track；
The left positioning strip or/and right positioning strip of positioner 3 are equipped with groove 6, and the opening direction of groove 6 faces connection strap 13
And ventilating duct, the inlet end connection blowing device 61 of ventilating duct are formed by the stop of connection strap 13, ventilating duct can circulate drying
The gas of cooling, preferably inertia compressed gas or nitrogen.
In order to there is a preferable cooling-down effect, the direction of ventilation in ventilating duct is consistent with the moving direction of stirring-head 5.
Since friction welding (FW) can produce substantial amounts of heat, the cooling gas blowed can take away most heat, Jin Erbao
Injury of the heat to core during shield welding.
Its operation principle is：
When being welded using the above scheme, lithium battery coiling core, lug, pole are pre-assembled, then pass through machinery
Core is placed on to device is supported by hand, and the action that two positioning strips clamp need to keep linking, thus ensure core to middle position
Put, avoid positioner from producing interaction force with clamping device, cause the injury to core.Positioner close to lug one
Side is equipped with groove, is equipped with through hole in end, after the completion of positioning, the stirring-head of welder starts to weld by desired guiding trajectory, at the same time
Blowing device starts to take away weldering by the straight slot on the inside of positioning strip from the inertia compressed gas for blowing hole and blowing dry cooling, gas
Caused heat is connect, gas is discharged from opposite side venthole.After the completion of welding, blowing device stops blowing gas.
Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
