Lithium battery batch code scanning system and method based on image processing

Abstract

The invention discloses a lithium battery batch code scanning system based on image processing. The system comprises an industrial personal computer (IPC), an image collection unit, and a movement control unit, wherein the IPC servers as core control equipment of the system; the image collection unit comprises an image collection card and a high-speed camera; and the movement control unit comprises a manipulator, a conveying belt, baffles, and position sensors. The invention further provides a lithium battery batch code scanning method based on the image processing, which comprises three steps, i.e., battery transportation, the image processing, and subsequent processing. The detection system and method adopting the real-time image processing has the advantages that in addition to a guaranteed code scanning accuracy, the traditional detection mode, in which lithium batteries are detected one by one, is changed, and batch detection of the lithium batteries is achieved, so that the detection efficiency is improved, and the lithium battery sorting time is shortened; and compared with other novel lithium battery batch detection systems and methods, the system and method achieves battery detection on the conveying belt and dispenses with unnecessary clamps, so that the equipment is greatly simplified, the equipment space is saved, and higher application value is achieved.

Description

technical field [0001] The invention relates to a lithium battery batch code scanning system and method based on image processing, belonging to the technical fields of machine vision and mechanical automation. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Due to the advantages of relatively long service life, high power tolerance, and environmental protection, lithium batteries have been widely used in the market. Applications. [0003] In the production process of lithium batteries, the voltage, capacity, internal resistance and other parameters of lithium batteries are different due to different production processes, so lithium batteries are divided into different grades. form is printed on the side of the lithium battery. For the convenience of subsequent operations, manufacturers need to detect lithium batteries by scanning barcode...

AI Technical Summary

Problems solved by technology

However, most of the scanning codes of lithium batteries now use code scanning guns to scan the codes of individual lithium batteries in sequence, which is inefficient and will affect the sorting efficiency of subsequent lithium batteries.

[0004] At present, several new lithium battery batch testing systems and methods have appeared, but most of the equipment is relatively complicated, and other fixtures are required to be used during the scanning process, or multiple cameras are used to shoot from all directions to solve the problem of inconsistent battery directions. question

Such a system increases equipment cost, equipment space and maintenance difficulty, and also reduces the efficiency of scanning codes
