New energy lithium battery cell appearance detection machine based on vision

Abstract

The invention discloses a new energy lithium battery cell appearance detection machine based on vision. The machine comprises a support, and further comprises a feeding device, a detecting device, a discharging carrying module and a conveying device. The feeding device is connected with the support, and the detecting device is used for detecting materials conveyed by the feeding device; the discharging carrying module is connected with the support, and the discharging carrying module carries out classified discharging on the materials according to detection results; the conveying device is connected with the support and used for conveying the materials conveyed by the discharging carrying module; the feeding device is used for continuously conveying the lithium battery cells to be detectedto the direction of the detecting device; the detecting device is used for detecting the appearances of the lithium battery cells, the discharging carrying module conveys the lithium battery cells tothe corresponding conveying device according to the detection result. The whole detection process is high in automation degree, manual intervention is not needed, the waste of human resources is reduced while the appearance detection quality is guaranteed, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of appearance inspection machines, in particular to an appearance inspection machine for lithium batteries based on new visual energy. Background technique [0002] At present, lithium-ion batteries are more and more widely used, such as mobile phones, notebooks, electric vehicles, etc., forming a huge industrial group. Among them, the battery cell is an intermediate product of lithium batteries in various forms, which can be assembled into batteries of different specifications through the packing process, such as lithium batteries for electric bicycles, lithium batteries for electric cars, etc. Since the shell of the cell is a soft composite material, the cell includes the cell body and the Mylar film covering the cell body; after the cell is produced, many quality problems are reflected in the appearance of the cell. Therefore, in the production process of the battery cell, it is necessary to take picture...

AI Technical Summary

Problems solved by technology

Since the shell of the cell is a soft composite material, the cell includes the cell body and the Mylar film covering the cell body; after the cell is produced, many quality problems are reflected in the appearance of the cell. Therefore, in the production process of the battery cell, it is necessary to take pictures of the appearance of the battery cell to detect, but the image integrity of the existing camera device is poor and the function is single, which affects the accuracy of judgment and is troublesome to use and low in efficiency.
