Problems solved by technology

The encapsulation of the sealant in such a packaging structure requires the upper and lower covers to be sealed after being assembled accurately, so as to ensure that the upper and lower covers will not be displaced, which brings certain challenges to the packaging process. the complexity of
Not only that, after a long time of use, this packaging structure is easy to cause the position of the upper and lower covers to be unstable due to the uneven injection of the sealant in the gap or the insufficient stability of the sealing layer; especially for explosion-proof button batteries When there is an explosion, this packaging structure can easily cause damage to the side wall of the cover, which will cause harm to the industrial electronic equipment to which it is applied. In severe cases, the explosion of the button battery may even damage the entire industrial electronic equipment Failure of equipment or the entire production line, resulting in obstruction of the production and processing process

Embodiment 1

[0045] Such as figure 1 , figure 2 , Figure 4 , Figure 5 As shown, the button battery packaging structure implemented by the present invention, which is beneficial to improve the assembly stability, includes an upper cover flange 1 arranged on the top edge of the upper cover, and a ring arranged on the top edge of the lower cover for An injection molded ring-shaped beading area 2, wherein the ring-shaped beading area 2 is recessed downward relative to the top surface of the lower cover;

[0046]At the same time, the implemented ring-shaped blanking area 2 and the outer wall of the lower cover are injection-molded to form a layer of sealant layer 3, and the formed sealant layer 3 is an integral structure, including an injection-molded sealant covering the outer wall of the lower cover by injection molding. part, and the injection-molded sealant part covering the ring-shaped beading area 2 at the edge of the top surface of the lower cover;

[0047] Correspondingly, the im...

Embodiment 2

[0053] Such as Figure 6-7 As shown, the button battery packaging structure implemented by the technical solution of the present invention is conducive to improving the assembly stability. Implement corresponding technical means and form corresponding technical solutions, including:

[0054] Several force application points 7 for applying pressure are respectively provided on the outer wall of the upper cover implemented. The technician may preferably set two force application points 7 on the same side of the upper cover, and the position is preferably the lower part of the cover;

[0055] Further, through the position of the force application point 7 on the outer wall surface, it can be squeezed inward, so that the corresponding part of the inner wall surface of the upper cover protrudes toward the center of the button battery. The sealant layer is injected, and each protrusion forms an internal pressure fixing part 6, and the internal pressure fixation part presses the seal...

Abstract

The invention relates to a button cell packaging structure facilitating the improvement of assembly stability. The packaging structure comprises an annular edge pressing area arranged at the edge of the top surface of a lower cover body, and also comprises an injection molding sealing part which comprises a top sealing glue layer and a side wall surface sealing glue layer which are connected intoa whole. The packaging structure further comprises an upper cover edge folding part which is arranged on the edge of the top of the upper cover body, wherein after the upper cover body and the lower cover body are assembled, the upper cover edge folding part is bent downwards from the straight edge state of standing upwards to the edge folding state of being tightly attached to the top sealing rubber layer. According to the invention, a reasonable assembly structure is adopted, and the injection molding sealing layer is arranged on the outer edge and the side wall surface of the top surface ofthe lower cover body, and then the injection molding sealing layer and the lower cover body are assembled in the upper cover body; the injection molding sealing layer on the outer edge of the top surface of the lower cover body is compressed through the upper edge pressing opening closing edge of the upper cover body, so a rigorous packaging structure is formed, the stability of the button cell packaging structure is improved, and particularly, the damage to the cover body and the whole cell due to sudden explosion conditions can be avoided.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a button battery packaging structure which is beneficial to improving assembly stability. Background technique [0002] Button battery is a kind of common battery, and its application scope includes the power supply of various electronic equipment and electronic products, such as computer motherboards, electronic watches, electric toys, pacemakers, counters, and some industrial electronic equipment. Generally speaking, those skilled in the art usually use stainless steel as the positive electrode for the material of the button battery, and a stainless steel circular cover for the negative electrode. The types of button batteries formed in this way can be further subdivided, including silver oxide batteries, lithium batteries, Alkaline manganese batteries, etc. [0003] Those skilled in the art know that when starting to develop various battery products and their peripheral tec...
