A lithium battery polar plate weighing instrument

Abstract

The invention belongs to the technical field of lithium battery production, and particularly relates to a lithium battery pole plate weighing instrument. The lithium battery pole plate weighing instrument comprises a bottom plate, a base, support rods, a weight box, a cone block, a weighing box, a detecting unit and a feeding unit. The base is fixedly connected to the middle portion of the bottomplate; the middle portions of the support rods are rotatably connected to the end of the base; the weight box is rotatably installed at one ends of the support rods; the cone block is rotatably connected to the other ends of the support rods, and the rotation point of the cone block is set over the center of gravity of the cone block; the weighing box is fixedly connected at the top of the cone block, and a rotating plate is rotatably installed at the end of the weighing box; the cone block is used for keeping the weighing box horizontal; the detecting unit is mounted on the bottom plate, andthe detecting unit is used for screening unqualified pole plates; and the feeding unit is arranged above the weighing box, and the feeding unit is used for transporting the pole plates. The feeding unit is arranged to transport the pole plates, the pole plates to be weighed are put into the weighing box, the weighing box sinks under the action of gravity, and when the weighing box sinks beyond theset value, the detecting unit works to screen out the unqualified pole plates.

Description

technical field [0001] The invention belongs to the technical field of lithium battery production, in particular to a weighing instrument for lithium battery polar plates. 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. [0003] There are also some t...

Problems solved by technology

[0004] This technical solution can weigh the polar plates, but it still has the following defects: when weighing the polar plates, it does not have the screening function, and workers need to manually remove unqualified polar plates according to the measured values, and at the same time, the powder in the weighing box cannot Automatic cleaning, resulting in dust accumulation, affecting the accuracy of measurement
