Abstract
The utility model relates to the jig of a kind of lithium ion cell positive ear ultrasonic bonding; comprise die main body, confined planes, working face, soldering tip protection hole slot and high-temp glue bed course; one of them angle of described die main body upper side is provided with a step; the horizontal plane of step is working face; working face is provided with high-temp glue bed course; the vertical side of step is confined planes, and the middle part of confined planes is provided with vertical soldering tip protection hole slot.Contribution of the present utility model has been to provide the jig of a kind of lithium ion cell positive ear ultrasonic bonding, adopt this mould, effectively guarantee that welding effect is in technological requirement scope, avoid due to anode ear fracture, effectively solder joint causes that preliminary filling fraction defective is high and to detect high internal resistance bad not; Relative other technique batteries of battery that adopt the utility model to produce, because anode ear welding uniformity is improved, the uniformity of battery performance improves.
Description
Technical field
The utility model relates to a kind of lithium ion battery and produces process units, particularly relates to the jig of a kind of lithium ion cell positive ear ultrasonic bonding.
Background technology
Current lithium ion battery is the advantages such as energy density is high, output voltage is high, have extended cycle life, environmental pollution is little owing to having, and in small size digital electronic product, are applied widely, and in fields such as electric automobile, Aero-Space, also have broad application prospects.Yet, at lithium ion cell positive ear and cover plate, carry out in ultrasonic bonding operation, easily occur that welding position difference is large, weldering print to connect on the lower side, easily causes cover plate and anode ear to rupture, and from face, causes that processing procedure scrappage is high, the bad height of preliminary filling, detects high internal resistance.One of them chief reason is exactly in super weldering process, lug and cover plate are without positioner, the position of welding is all determined by employee's sense organ, thereby cause welding effect to vary with each individual, weldering prints on the lower side, be welded in the first-class unfavorable condition of high-temp glue often generation, and new employee's introduction is slower, affects production efficiency and qualification rate.Therefore, study the mould of the super weldering of a kind of lithium ion cell positive ear location, guarantee that tab welding quality, minimizing operation easier are very important.
Summary of the invention
The purpose of this utility model is the defect for prior art, and the jig of a kind of lithium ion cell positive ear ultrasonic bonding is provided.
For achieving the above object, the utility model adopts following technical scheme:
The jig of a kind of lithium ion cell positive ear ultrasonic bonding; comprise die main body, confined planes, working face, soldering tip protection hole slot and high-temp glue bed course; one of them angle of described die main body upper side is provided with a step; the horizontal plane of step is working face; working face is provided with high-temp glue bed course; the vertical side of step is confined planes, and the middle part of confined planes is provided with vertical soldering tip protection hole slot.
Described die main body is cuboid, and two sides of working face are equilateral.
Described soldering tip protection hole slot is vertical semicircle hole slot, and the low side of hole slot is concordant with working face.
The panel of described high-temp glue bed course is corresponding with the big or small same position of solder side.
Contribution of the present utility model has been to provide the jig of a kind of lithium ion cell positive ear ultrasonic bonding, adopt this mould, effectively guarantee that welding effect is in technological requirement scope, avoid due to anode ear fracture, effectively solder joint causes that preliminary filling fraction defective is high and to detect high internal resistance bad not; Relative other technique batteries of battery that adopt the utility model to produce, because anode ear welding uniformity is improved, the uniformity of battery performance improves.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of one of them embodiment of the utility model.
Fig. 2 is the exploded sketch of Fig. 1.
Fig. 3 is welding job view.
The specific embodiment
As shown in Figure 1 to Figure 3; the utility model comprises die main body 4, confined planes 1, working face 2, soldering tip protection hole slot 11 and high-temp glue bed course 3; one of them angle of described die main body upper side is provided with a step; the horizontal plane of step is working face 2; working face is provided with high-temp glue bed course 3; the vertical side of step is confined planes 1, and the middle part of confined planes is provided with vertical soldering tip protection hole slot 11.Described die main body 4 is cuboid, and two sides 21,22 of the working face 2 of mould are equilateral.In use, die main body 4 is arranged on work top, and described soldering tip protection hole slot 11 is vertical semicircle hole slot, and the low side of hole slot is concordant with working face.The panel of described high-temp glue bed course 3 is corresponding with the big or small same position of solder side, and high-temp glue bed course 3 is bonding with working face 2.The utility model is by supersonic welding point location, prevents that artificial sense organ difference from causing weldering to print and depart from, and improves the uniformity of welding position, thereby improves the uniformity of welding quality, reduces that preliminary filling that human factor causes is bad and high internal resistance is bad.Welding method is: high-temp glue pad is placed in to working face and is adjacent to; Sky is stepped on supersonic welder, adjusts weldering and prints position to cover plate central authorities, is positioned in the middle of soldering tip protection hole slot 11 simultaneously; During welding, mould confined planes is close at cover plate 5 edges, and soldering tip protection hole slot be take as with reference to welding, as shown in Figure 3 in lug 6 positions.
