Abstract
It is a kind of to be used to solve lithium ion battery more and the device of fire is fried in spot welding, welding stage is increased into U-typed active block stop close to the edge of lower soldering tip, upper soldering tip is increased into crosspointer, and welding stage is brought up to concordant with the top of lower soldering tip.The utility model catches solder joint before can omitting spot welding, contraposition action, prevents that solder joint position is oblique due to adding U-shaped block positioning fool proof；Separately because upper soldering tip increases to crosspointer, therefore avoid repeating to single lug spot welding operation, make that solder joint distribution is consistent, and spot weld operation is simpler, and effectively avoid catching when spot welding off normal, contraposition inaccurate and fry fiery, dry joint phenomenon caused by causing same bond pad locations to repeat spot welding.Using the utility model device, due to the simplification of action, therefore unskilled employee also can easily be started to work, and process bottleneck problem is resolved.
Description
Technical field
It the utility model is related to one kind more and fiery protector fried in battery spot welding, and in particular to produced for lithium ion battery
Processing it is a kind of be used for solve lithium ion battery more and spot welding fry fire device.
Background technology
Current electronic model change is rapid, and portable product Individualized Pursuit improves constantly, product structure requirement becomes
In compact, keep for battery space tightly narrow, but to requiring that not anti-reflection adds after ETS estimated time of sailing, to enable lithium ion battery to be applicable more electricity
Sub- product, on the premise of product structure is not changed, as far as possible using space in product, reach the mesh for doing big battery capacity
, production technology passes through spot welding using overlapping parallel connection above and below the more battery cores of lithium ion battery, its connected mode between each cell polar ear
Make positive pole overlapping with positive pole, negative pole is overlapping with negative pole, realizes effect in parallel.
Lithium ion battery cell group is realized in parallel process, due to three odjective causes, is also easy to produce fried fire, is caused lug to be worn
Hole problem：
Reason 1：There is tolerance in the centre-to-centre spacing between each battery core positive and negative electrode, have dislocation phenomenon above and below the lug of overlapping battery core group；
Reason 2：To ensure the firmness of welding, meeting process requirements, the solder joint number being distributed on lug must be more than 2, therefore
Spot welding operation needs to move battery core group, realizes that the number of welds on lug is up to standard；
Reason 3：Because spot-welding equipment platform is less than butt-joint point, there is no positioner on platform, manual working is difficult in welding
To capture suitable bond pad locations.
Point welding process is the critical process of PACK technologies of the package, and bottleneck process, directly affects product quality, production effect
Rate；Therefore improvement processing mode, lifting the demand of quality becomes more urgent.
The content of the invention
In order to overcome existing production technology deficiency, the fried fire of spot welding is eliminated, lug perforation problem, the utility model provides a kind of
Spot welding protector reasonable in design, easy to operate.
The utility model construction is compact to be applicable, and is easy to promote, and solves 1, overlapping battery core group lug and has dislocation up and down, 2,
Lug increase solder joint must move battery core, 3, welding stage less than butt-joint point without the fried fire of spot welding caused by three reasons of positioning, lug perforation
Problem, effectively eliminate lithium ion battery cell and organize the operation bottleneck of spot-welding technology.
The technical solution of the utility model is：A kind of for solving lithium ion battery, simultaneously the device of fire is fried in spot welding more, will weld
Platform increases U-typed active block stop close to the edge of lower soldering tip, upper soldering tip is increased into crosspointer, and welding stage is brought up to and lower soldering tip
Top is concordant；Battery pack lug that lug is misplaced by " U " block or so is pushed, and makes dislocation lug width control system in U-shaped gear
In block；By upper soldering tip crosspointer butt-joint, realize that the gimmick for omitting the movement of battery core group still meets solder joint number；By raising welding stage,
Lug is set to be positioned at lower soldering tip tip position.
The beneficial effects of the utility model are, due to adding U-shaped block positioning fool proof, weldering to be caught before can omitting spot welding
Point, contraposition action, prevents that solder joint position is oblique；Separately because upper soldering tip increases to crosspointer, therefore avoid repeating to single lug spot welding operation, make
Solder joint distribution is consistent, and spot weld operation is simpler, and effectively avoids causing same solder joint position because catching inaccurate when spot welding off normal, contraposition
Fried fire, dry joint phenomenon caused by putting repetition spot welding.Using the utility model device, due to the simplification of action, therefore unskilled employee
Also can easily start to work, process bottleneck problem is resolved.

Embodiment
Specific embodiment of the present utility model is：And organize after the upper and lower lug of battery core inserts U-shaped block, start mash welder
Pneumatic foot push, makes soldering tip crosspointer and lower soldering tip copper post while extruding is to battery core group lug up and down to be welded, forms one
Fixed contact resistance, and welding current flows through lower soldering tip copper post to cell polar ear and forms loop, in lug from the capillary of upper soldering tip
The point of resistance contacted with capillary forms the thermal welding of moment, realizes and welds and organize function.
Specific implementation step is：
1st, equipment pressure, welding current, welding stage height have been debugged in setting；
2nd, take the battery core group combined to be pushed on the left of lug by U-shaped block, asked for correcting cell polar ear dislocation up and down
Topic；
3 and then battery core is lain on welding stage, lower cell polar ear is contacted with lower soldering tip copper post；
4th, stepping on floor push makes soldering tip crosspointer vertical drop, is pressed onto cell polar ear and performs spot welding operation；
5th, the sustainable welding batch jobs of 2-4 steps are repeated.
