Description

Technical Field

[0001] The utility model relates to the field of alkaline manganese battery manufacturing, and more specifically, to an alkaline manganese battery secondary shaping device. Background Art

[0002] Alkaline batteries are widely used around the world because of their simplicity, durability, and long life. In order to increase the service life of the battery and reduce the production scrap rate, the battery seal strength needs to be improved. The secondary battery shaping process is to add a secondary strengthening effect on the basis of the primary battery seal. By further strengthening the battery seal, the battery shell and seal can resist the pressure shock caused by the large amount of gas generated by the internal chemical reaction during the charging and discharging process, ensuring the safety of the battery and avoiding dangerous situations such as leakage and explosion during the use of the battery. Therefore, the battery sealing process is very critical and determines the service life and safety factor of the battery.

[0003] The traditional battery sealing process, due to poor assembly workmanship during the manufacturing process, will lead to unstable sealing strength, which will have a certain impact on the battery's service life and safety factor. It is a difficult-to-control factor in the battery product process. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides an alkaline manganese battery secondary shaping device, so as to solve the problem of unstable sealing strength caused by poor assembly work in the manufacturing process in the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An alkaline manganese battery secondary shaping device comprises a turret, an upper shaping assembly and a lower shaping assembly;

[0007] The turret comprises a rotating shaft, an upper cam, a mounting plate, and a lower cam, wherein the upper cam, the mounting plate, and the lower cam are mounted on the turret from top to bottom;

[0008] The upper shaping assembly includes an upper roller bearing, an upper guide rod, an upper fixing assembly, and an upper shaping mold. The upper fixing assembly is mounted on the mounting plate, the upper roller bearing is mounted above the upper guide rod, the guide rod passes through the upper fixing assembly, and the upper shaping mold is mounted below the upper fixing assembly.

[0009] The lower shaping component includes a lower roller bearing, a lower guide rod, a lower fixing component, and a lower shaping mold. The lower fixing component is installed on the mounting plate, the lower roller bearing is installed below the lower guide rod, the lower guide rod passes through the lower fixing component, and the lower shaping mold is installed above the lower fixing component.

[0010] By placing the battery that has been curled once into the lower shaping mold, and pushing the battery into the designated positions of the upper shaping mold and the lower shaping mold by the upper guide rod and the lower guide rod, the battery can be reshaped for the second time to improve the sealing strength of the battery.

[0011] A further technical solution is that the upper shaping mold is a shaping mold, and the lower shaping mold is a fixed mold;

[0012] The fixed mold is provided with a trumpet-shaped opening at one end, and the rear end of the trumpet-shaped opening is a positioning groove and a guide rod hole;

[0013] The shaping die is provided with a trumpet-shaped opening at one end, and a curling ring and a guide rod hole are provided at the rear end of the trumpet-shaped opening;

[0014] The diameter of the curling ring is smaller than the diameter of the unshaped battery.

[0015] The trumpet-shaped openings of the fixed mold and the shaping mold are used to guide the assembly and movement of the battery. The diameter of the positioning groove of the fixed mold is smaller than the diameter of the battery. The battery is initially placed in the fixed mold and is limited by the limiting groove.

[0016] The diameter of the curling ring is smaller than the diameter of the unshaped battery. When the battery is pushed to the position of the curling ring, the outer side of the battery is deformed and curled.

[0017] A further technical solution is that the upper shaping mold and the lower shaping mold are made of zirconia ceramic material.

[0018] Zirconia ceramics have the characteristics of high hardness, low adhesion and high surface finish during use, and are suitable for battery molding. During use, zirconia ceramics do not produce magnetism, will not adhere to metal powders such as nickel powder, and have an extremely low friction coefficient, which can effectively solve the problems of high friction generated during the shaping process, nickel powder adhesion causing battery barrel strain, and battery positive pole depression.

[0019] A further technical solution is that the upper fixing assembly includes an upper fixing plate, an upper sleeve, and an upper fixing frame;

[0020] The upper fixing plate is installed on the mounting plate, and the upper sleeve and the upper fixing frame are installed on the upper fixing plate;

[0021] The upper fixing frame is located below the upper sleeve, and the upper shaping mold is installed below the upper fixing frame.

[0022] Compared with the prior art, the utility model has at least the following beneficial effects: the utility model can realize secondary shaping of the battery by loading the battery that has undergone one curling into the lower shaping mold, and pushing the battery into the designated positions of the upper shaping mold and the lower shaping mold by the upper guide rod and the lower guide rod, thereby improving the sealing strength of the battery, ensuring the safety of battery use, and avoiding dangerous situations such as leakage and explosion during battery use.
