Abstract
The utility model discloses a battery cap, which comprises a cap, an aluminum sheet, air holes and breaking-prevention welding spots, wherein the aluminum sheet is arranged on the inner surface of the top of the cap; the air holes and the breaking-prevention welding spots are arranged on the aluminum sheet; and an additional lug of the cap is arranged on the aluminum sheet. The utility model has the advantage that the welding operation for the battery cap is more convenient, faster and firmer, thereby greatly improving the working efficiency of welding a battery cell and the cap. The battery cap with the additional lug can be manufactured by directly communicating with suppliers, thereby saving manpower and material resources. Meanwhile, the battery cell and the cap are welded with each other ultrasonically, thereby lowering the production cost of equipment, reducing the power consumption and lowering the processing cost of a battery.
Description
Technical field
The utility model relates to cylindrical lithium ion battery and makes the field, especially relates to battery cap.
Background technology
Internal electrical core and block welding method are essentially the internal electrical core and draw lug and be welded on the aluminium flake of battery cap inside by laser welder in the existing lithium ion battery production, complicated operation, low, the easy sparking of efficient penetrate cell polar ear and cause failure welding, and welding needs special personnel to weld.Use in addition that laser welder power consumption is big, the laser welder cost is higher, improved the production cost of battery.
The utility model content
The utility model purpose is to provide a kind of battery cap that reduces the battery production cost, is convenient to welding operation.
For achieving the above object, the utility model can be taked following technical proposals:
Battery cap described in the utility model, it comprises block, is arranged on aluminium flake on the described block top inner surface and pore disposed thereon, anti-breaking solder joint; Described aluminium flake is provided with the additional lug of block.
Described block interpole ear length degree is the 10-30 millimeter, and thickness is 0.05-0.20mm.
The utility model advantage is to make the battery cap welding operation more convenient, firm, has improved the operating efficiency of battery battery core with the block welding greatly.The battery cap of the additional lug of band can directly be linked up making with supplier, has saved manpower and materials.Realize that simultaneously the welding of electric core and block takes ultra-sonic welded, reduced the production equipment cost, saved power consumption, reduced the battery processing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the electric core of battery is drawn lug and the additional lug welding of block schematic diagram.
Embodiment
As shown in Figure 1, 2, battery cap described in the utility model, it comprises block 1, is arranged on aluminium flake 2 on described block 1 top inner surface and pore 3, anti-breaking solder joint 4 disposed thereon; Be positioned at anti-breaking solder joint 4 one face down bondings and be connected to the additional lug 5 of the block of being made by aluminium matter or other conductive material on described aluminium flake 2, the length of the additional lug 5 of described block is the 10-30 millimeter, and thickness is 0.05-0.20mm; The additional lug 5 of will blocking a shot during use is turned up 90 degree and is made it and the 1 one-tenth plumbness of blocking a shot, the additional lug 5 of will blocking a shot afterwards is close to the bottom head place with ultrasonic bonder, electric core drawn lug 6 is parallel to be leaned against above the additional lug 5 of block, pin is stepped on the supersonic welder pedal and is carried out ultra-sonic welded and get final product.
