Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a movable visual edge detection device. Background Art

[0002] Existing edge detection mechanisms rely on manual measurement and calculation to find the appropriate detection position during the edge detection process. A thick embossed knob fixes the detection device to the guide rail for monitoring. The CCD uses image feedback to detect the distance between the blank spaces at both ends. If a deviation from the set blank space is detected, the data will be transmitted to the PLC system to control the gravure roller movement motor to adjust the area where the slurry is applied to the substrate, ensuring the relative distance between the substrate and the slurry coating area, improving the quality of the subsequent welding tabs, and thus completing the entire edge detection process. However, the edge detection mechanism of the existing technology can only be manually adjusted when detecting the blank space of the substrate film, which is relatively time-consuming and labor-intensive. In addition, the detection position needs to be re-measured and calculated every time a substrate of a different size is changed, resulting in low data accuracy.
