A lithium battery production process

Abstract

The invention belongs to the technical field of lithium battery production, and specifically relates to a lithium battery production process. The process adopts a weighing instrument, and the weighing instrument includes a base plate, a base, a pole, a weight frame, a tapered block, and a weighing instrument. Box, detection unit and feeding unit; the base is fixedly connected to the middle of the bottom plate; the middle part of the pole is connected to the end of the base in rotation; one end of the pole is rotatably mounted with a weight frame; The rotation point of the shaped block is set directly above the center of gravity of the conical block; the weighing box is fixedly connected to the top of the conical block; the conical block is used to keep the weighing box level; the detection unit is installed on the bottom plate and is used to screen out Unqualified plates; the feeding unit is set above the weighing box, and the feeding unit is used to transfer the plates. The invention sets the feeding unit to transfer the pole plate, puts the pole plate to be weighed in the weighing box, the weighing box sinks under the action of gravity, and when the weighing box sinks beyond the set value, the detection unit works Screen out unqualified plates.

Description

technical field [0001] The invention belongs to the technical field of lithium battery production, in particular to a lithium battery production process. Background technique [0002] In the production process of lithium batteries, a very important process is to weigh the plates, that is: weigh both the positive and negative plates in the lithium battery, and remove the overweight and too light plates after weighing , and classify the plates that meet the requirements into several files according to the weight level, and then collect them separately by category. In this way, when assembling the lithium battery, it can be reasonably matched according to the weight of the polar plate, so that the electrical properties of the lithium battery are basically consistent, and at the same time, there may be some powder dust attached to the polar plate, which remains in the weighing box , resulting in inaccurate weighing measurements. The traditional process requires manual measurem...

Problems solved by technology

[0004] Using this method to weigh the pole plate can realize automatic weighing, but this method also has the following defects: when weighing the pole plate, it does not have the screening function, and workers need to manually remove unqualified pole plates according to the measured value, so that The production efficiency is low, and at the same time, the powder in the weighing box cannot be cleaned automatically, resulting in the accumulation of powder, which needs to be cleaned manually
