Abstract
The utility model discloses a tab folding fixture for a square laminated lithium ion battery. The tab folding fixture comprises a battery core positioning groove (1). A positive tab positioning groove (2) and a negative tab positioning groove (3) are extended in parallel from one end of the battery positioning groove (1). A square through hole is reserved between the battery core positioning groove (1) and the positive tab positioning groove (2), and a square through hole is also reserved between the battery core positioning groove (1) and the negative tab positioning groove (3). One side of each square through hole is closed to the battery core positioning groove (1), and a welding spot positioning groove (4) is reserved on the inner wall of the side. A cover plate (6) covers the battery core positioning groove (1). The tab folding fixture is simple in structure, tabs can be quickly positioned and folded, the parallelism of the tabs and a battery core is ensured, consistency is ensured, production efficiency is greatly improved, and the safety performance of the battery is also greatly improved.
Description
Technical field
The utility model relates to a kind of lithium ion battery manufacture field, relates in particular to a kind of instrument of square lithium-ion laminated batteries lamination folding lug.
Background technology
At present during square lithium-ion laminated batteries lamination; Generally positive/negative plate, barrier film are intersected to place and accomplish by manual work; This kind operational drawbacks mainly contains: can't guarantee the depth of parallelism of lug and electric core, cause that positive/negative plate and barrier film replace dislocation and cause electric core security performance to descend easily, its consistency that can't guarantee laminated batteries is low simultaneously.
The utility model content
The utility model technical problem to be solved is to provide a kind of lamination quick, the square lithium-ion laminated batteries lamination aid of accurate positioning.
The technical scheme of the utility model is following: a kind of square lithium-ion laminated batteries folding lug anchor clamps; Its key is: comprise battery location notch (1); Said battery location notch (1) one end extension is set side by side with anode ear location notch (2) and negative electrode lug location notch (3); Have square through hole between said battery location notch (1) and anode ear location notch (2) and the negative electrode lug location notch (3); This square through hole leans on battery location notch (1) one side inwall to have solder joint location notch (4), and said battery location notch (1) is covered by cover plate (6).
Above-mentioned solder joint location notch (4) be two corresponding one by one on Width with anode ear location notch (2) and negative electrode lug location notch (3) respectively.Groove position according to electric core width, lug width, both positive and negative polarity ear space designs fix; Before the folding lug electric core is placed on fixing position and covers pressing plate; Barrier film and blade portion are divided keep relative fixed, with the lug bending, solder joint, lug are embedded in the groove position of fixed width respectively then.Guarantee lug and electric core keeping parallelism behind the bending lug, eliminate the electric core safety problem that the bending lug causes that barrier film and pole plate dislocation possibly cause, improve and produce electric core consistency.
Beneficial effect: the utility model is simple in structure, has realized quick positioning flaps, and putting down of lug and electric core guarantees consistency, improved production efficiency greatly, also promoted the security performance of battery greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1; A kind of square lithium-ion laminated batteries folding lug anchor clamps; Comprise battery location notch 1, said battery location notch 1 one ends extension is set side by side with anode ear location notch 2 and negative electrode lug location notch 3, has square through hole between said battery location notch 1 and anode ear location notch 2 and the negative electrode lug location notch 3; This square through hole leans on battery location notch 1 one side inwalls to have solder joint location notch 4, and said battery location notch 1 is covered by cover plate 6.Said solder joint location notch 4 be two corresponding one by one on Width with anode ear location notch 2 and negative electrode lug location notch 3 respectively.
Although more than combine accompanying drawing that the preferred embodiment of the utility model is described; But the utility model is not limited to above-mentioned embodiment; Above-mentioned embodiment only is schematic rather than determinate, and those of ordinary skill in the art is under the enlightenment of the utility model, under the prerequisite of the utility model aim and claim; Can make multiple similar expression, such conversion all falls within the protection range of the utility model.
