The basket circulation mechanism 3 reduces the footprint of the equipment for transporting low-frequency solar cells and reduces the amount of transport equipment, thereby reducing the footprint and improving the accuracy and efficiency of the conveying.

[0029] The high-frequency sorting section 1 includes several high-frequency sorting mechanisms 102 and a high-frequency transmission mechanism 103. The high-frequency sorting mechanisms 102 are correspondingly arranged with several high-frequency transport modules 101. Furthermore, the high-frequency sorting mechanisms 102 are arranged sequentially along the conveying direction of the high-frequency transmission mechanism 103. The high-frequency sorting mechanisms 102 are located on one or both sides of the high-frequency transmission mechanism 103. The high-frequency transmission mechanism 103 uses a conveyor belt to transport the battery cells. The conveyor belt is driven by a motor. The high-frequency sorting mechanisms 102 are used to sort the high-frequency battery cells. At the same time, the high-frequency transport modules 101 correspond one-to-one with the high-frequency sorting mechanisms 102. The high-frequency transport modules 101 are used to transport and convey the sorted high-frequency battery cells. In addition, the high-frequency sorting mechanism 102 is existing technology and will not be described in detail.
