Battery cell appearance visual inspection equipment and detection method thereof

Abstract

The invention discloses battery cell appearance visual inspection equipment and a detection method thereof. The battery cell appearance visual inspection equipment comprises a first shooting station, a battery cell clamping and conveying mechanism, a second shooting station and a battery cell conveying and rotating mechanism, wherein the bottom surface or top surface of a battery cell is subjected to image acquisition by a shooting module at the first shooting station; the battery cell clamping and conveying mechanism is at least used for clamping at least one battery cell and driving the battery cell to move to the upper side or lower side of the first shooting station; other five surfaces of the battery cell are subjected to image acquisition twice by virtue of three shooting modules at the second shooting station; and the battery cell conveying and rotating mechanism can fix and drive the battery cell positioned thereon to rotate and convey the battery cell to a blanking station after the image is acquired at the second shooting station. According to the battery cell appearance visual inspection equipment disclosed by the invention, the requirement for detecting the six surfaces of the battery cell can be met by adopting the four shooting modules, partial shooting modules are saved, and the equipment cost is greatly reduced. Moreover, when six-surface detection of the battery cell is met, the assembly line type online detection of the battery cell is effectively met by the conveying mechanism, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric core processing, in particular to a visual detection device for the appearance of electric cores and a detection method thereof. Background technique [0002] In recent years, smog has begun to plague many cities in our country. As the "backbone" of smog, automobile exhaust has been criticized by the whole society. New energy vehicles can effectively solve this problem and have begun to receive widespread attention from the whole society. The development of new energy vehicles has become the consensus of the whole society including the government, enterprises and the people. [0003] The vigorous development of new energy vehicles has led to an increasing demand for new energy batteries. With the increase in production, more and more accidents occurred during production and use. Improving the qualification rate of new energy batteries is the top priority in the current production process. [0004] In th...

Problems solved by technology

[0007] The current visual inspection equipment for the appearance of three-dimensional parts is generally only used for the inspection of a certain or part of the surface of the workpiece. To perform six-sided inspection, it is often necessary to set up a camera module for each surface to collect images. Among them, the camera module Groups are the main components of visual inspection equipment and are expensive. The more the number, the greater the cost of the equipment. Therefore, it is necessary to minimize the number of camera modules to meet the image acquisition requirements of the six sides.
