Battery size optical measurement method and system

Abstract

The invention relates to a battery size optical measurement method and system. The method comprises the following steps that a measurement background and a point light source are provided, a battery to be measured is placed between the measurement background and the point light source, the main surface of the battery to be measured is toward the point light source, the distance S0 between the point light source and the measurement background is measured, and the distance S1 between the point light source and the main surface, toward which the point light source is, of the battery to be measured is measured; the point light source is controlled to irradiate the battery to be measured, a first projection image of the battery to be measured is formed on the measurement background, and the size of the image is measured; and according to the distance S0, the distance S1 and the size of the first projection image, the size of the battery is computed. The measurement system comprises a point light source, a measurement background and a projection size measuring element. According to the method and system, optical projection imaging is used, the size of the battery can be computed by determining the image size, operation is easy, convenient, quick and efficient, accuracy is high, human factor interference is eliminated, and the misjudgment rate is reduced. Measuring results are accurate and reliable, data can be checked and retraced, monitoring and analyzing processing are convenient, and enterprise competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery size optical measurement method and system thereof. Background technique [0002] With the continuous development of electronic products, lithium-ion batteries have been widely used, and the current electronic products are constantly being updated, and the requirements for lithium-ion battery products are also getting higher and higher. At present, in the entire battery industry, the product quality of each battery manufacturer is different, and 90% of the manufacturers are in the low-end level. For some high-demand electronic products, the battery performance cannot meet the requirements. For example: in the early days, it was mainly Based on Bluetooth, the performance requirements for batteries are not very high. As long as enterprises with a certain amount of funds can invest in the lithium-ion battery industry, and from the current market point of view, the main e...

Problems solved by technology

However, the existing measuring equipment is usually a vernier caliper and other fixtures. Through manual measurement, data recording, and manual analysis, these are all manual operations, which are prone to mismeasurement and mismeasurement. The error is large, the data is easy to lose, and the analysis data is slow.

On the other hand, especially for the soft material of the outer package of the pouch battery, it is not suitable to use these measurement equipment, the measurement results are easily affected by human factors, and this traditional measurement equipment is inefficient, labor-intensive, and misoperation high probability
