X-Ray- based battery cell detecting method

Abstract

The invention belongs to the technical field of battery cell manufacturing, and particularly relates to an X-Ray-based battery cell detecting method. The X-Ray- based battery cell detecting method comprises the following steps: S1, preliminary detection: carrying out automatic preliminary X-detection on battery cells by an X-Ray machine, and transferring the qualified battery cells to a visual detection area, and the unqualified battery cell entering the next step of detection; S2, system judgment: calling the picture information of the unqualified products in the S1, generating a virtual screen ruler, detecting the battery cells by using the screen ruler, and transferring the battery cell which is detected to be qualified to a visual inspection area; S3, visual inspection: carrying out visual inspection on the battery cells transferred in the S1 and the S2, and discharging the battery cells passing the visual inspection to a finished product warehouse; S4, reinspection: carrying out X-ray inspection again before delivery of the battery cells. Through the above steps, unqualified battery cells are effectively prevented, the quality of the battery cells is improved. The judgment ofa system is objective, and subjective factors of manual inspection are reduced. In addition, the production efficiency is improved, and the production cost is saved.

Description

technical field [0001] The invention belongs to the technical field of electric core manufacturing, and in particular relates to a method for detecting electric cores based on X-Ray. Background technique [0002] As a new generation of high-efficiency green energy, batteries have the advantages of small size, high working voltage, high energy density, and no memory effect, and are widely used in various industries. In the production and manufacture of electric cores, the electric cores often need to be inspected by X-Ray after packaging (that is, using the transmission principle of X-rays to penetrate the electric cores without damaging the electric cores. Different materials have different degrees of absorption of X-rays, and obtain a clear internal structure image of the battery, so as to quickly detect the defects inside the battery to judge whether the battery meets the requirements). However, in the prior art, the battery manufacturer is In this process, the automatic ...

Problems solved by technology

[0003] 1) After the automatic X-ray test, overkill ("overkill" means that when judging whether a product is good or bad, the judgment data is at a critical point. In order to ensure that the output of this process is a good product, those that are both like Good or bad products are judged as defective) batteries will enter the manual X-Ray and subsequent visual inspection, and the unqualified products in the overkill batteries have no obvious difference in appearance from normal batteries. It is easy to mix into qualified batteries, and cannot be picked out in the appearance inspection;

[0004] 2) The current testing process is mainly manual judgment, which cannot realize the objective judgment of the system and serve as the basis for the shipping standard;

[0005] 3) The equipment cost and labor cost of manual X-Ray detection are huge, and the production efficiency is low
