Easy to get started! Front and back inspection of lithium battery explosion-proof plate assembly
The structure of lithium battery cover plate is complex and precise, composed of more than 10 types of components. How to achieve front and back detection of explosion-proof plates in the assembly of lithium battery cover plates.The shell of a new energy square shell battery consists of a shell and a cover plate. The battery cover plate is a key component that seals the shell with the battery cell, outputs internal energy, and ensures the safety of the battery cell. It has strict requirements for component sealing, safety valve pressure relief, electrical performance, size, and appearance.
The structure of lithium battery cover plate is complex and precise, consisting of more than 10 components, mainly composed of cover plate, positive and negative pole columns, injection hole, flip plate, explosion-proof plate and other structures. The structure is precise and complex.
In this issue, Xiaoming will share with you how to achieve front and back detection of explosion-proof plates in the assembly of lithium battery cover plates.

Scene requirements
Distinguish the AB side of the explosion-proof plate within the red box in the following figure

Design Plan
The Akusense Vision Sensor VDS10 series is used for detection. The detection principle is that under the imaging of the camera, the circular arcs around the A surface of the explosion-proof film will have strong reflections. The presence or absence of spots in the visual sensor tool can be used to detect the presence or absence of white reflections, thereby distinguishing the AB surface of the explosion-proof film.
