Further, the upper folded portion and the lower folded portion are symmetrically disposed along the folding line.
Furthermore, the pressing position where the die plate is inserted into the sealing machine is flush with the insulation glue of the outer pole lug.
Further, the thickness of the die plate is equal to the thickness of the outer tab insulation glue plus the thickness of the outer tab.
The utility model provides a pair of be used for lithium cell top to seal leak protection device night's advantage lies in: the utility model discloses a be used for lithium cell top sealing leak protection night device that provides in the structure, the mould board thickens between the outer utmost point ear of top seal side and both sides position for top seal one side thickness is the same, has avoided the battery weeping defect that the sealing is not tight to cause, reaches the best effect of sealing, and the mould board wraps up partial outer utmost point ear simultaneously, in the process of top sealing, plays the guard action to the outer utmost point ear of setting up in the electricity core outside; the length of the mould plate can not be overlong, and the mould plate can not be pressed on the battery cell, and the mould plate only needs to be flush with the outer tab insulating glue when being inserted into the pressing part of the sealing machine.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of a mold plate;
the method comprises the following steps of 1-die plate, 2-notch, 3-pressing part of a sealing machine, 4-outer tab, 5-outer tab insulating glue, 6-aluminum plastic film, 11-upper folding part and 12-lower folding part.
Detailed Description
The technical solutions of the present invention are explained in detail below with reference to specific embodiments, and many specific details are set forth in the following description to provide a thorough understanding of the present invention. The present invention can be embodied in many other forms than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention.
As shown in fig. 1 to 2, the utility model provides a be used for lithium cell top to seal leak protection device night, including folding mould board 1, notch 2 has been seted up respectively at the both ends of keeping away from the folding line to mould board 1, and the department of pressing 3 of capper is inserted after the outer utmost point ear 4 of the folding parcel of mould board 1, notch 2 and the attached setting of outer utmost point ear 4.
When carrying out the top seal to the lithium cell, because the addition of outer utmost point ear 4 for top seal one side thickness differs, and the position thickness of outer utmost point ear insulating cement 5 is greater than the thick end of other positions, does not have soft pressure or soft pressure effect relatively poor condition when the capper under, and the position that does not have the insulating cement is thinner probably can not be pressed, leads to sealing not tight and leads to the fact the battery weeping. Therefore, the mold plate 1 improves the defect, the mold plate 1 thickens the top sealing side outer lug 4 and the positions of the two sides of the outer lug 4, the thickness of one side of the top sealing is the same, the best sealing effect is achieved, and meanwhile, the mold plate 1 wraps the partial outer lug 4 and plays a role in protecting the outer lug 4 arranged outside the battery cell in the top sealing process.
In the specific use process of the die plate 1, the die plate 1 comprises an upper folding part 11 and a lower folding part 12 rotatably connected with the upper folding part 11, two notches 2 are respectively arranged at two ends of the upper folding part 11 and the lower folding part 12 far away from a folding line, the size of each notch 2 is the same, and the upper folding part 11 and the lower folding part 12 are symmetrically arranged along the folding line.
Because the battery generally has two utmost point ears, therefore all set up two notches 2 on last folded portion 11 and lower folded portion 12, after mould board 1 is folding, because four notches 2 set to the size unanimous, therefore notch 2 on the last folded portion 11 can directly be attached outer utmost point ear 4 and be located notch 2 department with the notch 2 of lower folded portion 12 to avoid increasing the thickness of outer utmost point ear insulating cement 5 department, can carry out thickness improvement to the position in the outer utmost point ear 4 outside again simultaneously, make top seal one side thickness the same.
It should be noted that the mold plate 1 cannot be too thick so as to prevent the sealing machine from pressing the contact position of the outer tab insulating glue 5 and the aluminum-plastic film 6, and when the thickness of the mold plate 1 is equal to the thickness of the outer tab insulating glue 5 plus the thickness of the outer tab 4, the effect that the thickness of the top sealing side is the same can be achieved. The length of the mould plate 1 can not be overlong, and the mould plate 1 can not be pressed on the battery cell, and the mould plate 1 only needs to be flush with the outer tab insulating glue 5 when being inserted into the pressing part 3 of the sealing machine.
The working process is as follows: in the lithium cell carries out the top and seals the operation, fold module board 1 through the folding line, insert the department 3 of pressing of capper behind the outer utmost point ear 1 of parcel part, adjust the position relation of notch 2 and outer utmost point ear 1 of module board 1 for outer utmost point ear insulating cement 5 all is in notch 2 department, and this then the department 3 of pressing of capper fastens, and then carry out the top and seal can.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
