[0022] Furthermore, in one embodiment of the present invention, a vibration device is provided on the conveying device 2 to separate the overlapping electrode sheets through the vibration function, so as to facilitate the separation of the positive and negative electrode sheets by the suction separation device 4.

[0023] Furthermore, in one embodiment of the utility model, the intelligent sorting system for positive and negative electrode sheets also includes a disperser and a linear screening machine.

The color sorting and identification device 3 above the conveying device 2 identifies the positive and negative electrode sheets and sends the results to the suction separation device 4. The suction separation device 4 above the conveying device 2 uses the pipeline negative pressure method to suck out the negative electrode sheets and leave the positive electrode sheets, completing the sorting of the positive and negative electrode sheets. The use of negative pressure separation can effectively solve the problem of powder particles floating during the sorting process.

[0026] Furthermore, the color sorting and identification device 3 captures the image or color information of the electrode piece through an optical sensor or a camera, and the computer analysis terminal 7 completes the image processing and analysis and sends the analysis result to the suction separation device 4 .
