Embodiment Construction

[0031] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific embodiments.

[0032] like figure 1 As shown, a lithium battery production process according to the present invention, the process comprises the following steps:

[0033] s1: Put the electrode active material, binder, etc. into the spiral reamer scale for weighing;

[0034] s2: Mix the electrode active material, binder, etc. weighed in s1 into a solvent and put it into a vacuum mixer to stir evenly to form a slurry;

[0035] s3: coating the slurry in s2 on the metal foil, and baking, rolling and slitting to make a lithium battery plate;

[0036] s4: transport the lithium battery plate in s3 to the next process;

[0037]Among them, the spiral reamer scale includes a storage hopper 1, a first conveying mechanism 2, a crushing mechanism 3, a blanking mechan...

Abstract

The invention relates to the technical field of lithium battery production, and specifically relates to a lithium battery production technology. The lithium battery production technology uses a spiralreamer scale. The spiral reamer scale includes a storage bin, a first conveying mechanism, a breaking mechanism, a blanking mechanism, a weighing mechanism, a cushioning mechanism, a blower and a second conveying mechanism, wherein storage of materials can be realized through the storage bin; the first conveying mechanism can realize conveying of materials; the breaking mechanism can realize breaking of materials; the blanking mechanism is convenient for conveying the materials to the inside of the weighing mechanism to perform accurate weighing; the cushioning mechanism can alleviate vibration between the two conveying mechanisms, thus improving the weighing accuracy; the blower cooperates with the second conveying mechanism to output the materials completely and conveniently; through the breaking mechanism, the dropped conveyed materials are knocked to avoid directly dropping of the caked materials so as to prevent inaccurate weighing, and at the same time internal blocking can be effectively eliminated; and when a lever is weighed at a suitable weight, blanking can be controlled with accuracy and high speed.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a lithium battery production process. Background technique [0002] The screw reamer scale adopts the powder steady flow quantitative feeding screw, which integrates powder material transportation, weighing measurement and quantitative feeding control. Powder material continuous measurement and batching control system; can be widely used in powder material measurement process links in building materials, metallurgy, electric power, chemical and other industries. [0003] The existing spiral reamer scales are weighed in the spiral conveying, and the vibration is large during the spiral conveying, which is easy to cause inaccuracy in weighing; during the production of lithium battery plates, it is necessary to weigh the electrode active materials, binders, etc. ; When weighing, the powder material is easy to agglomerate, which is not only easy to block, but also...
