Multi-layer carrier plate carrying system and method

The embodiment of the invention provides a multi-layer carrier plate carrying system and method, and relates to the technical field of solar cell production. A multi-carrier-plate lifting and carrying device of the multi-layer carrier plate carrying system is arranged above a conveying belt and can move into the top of a multi-carrier-plate caching and lifting device, and a multi-layer carrier plate caching frame capable of moving between the top and the bottom in a lifting mode is arranged in the multi-carrier-plate caching and lifting device. The multi-carrier-plate lifting and carrying device is configured to be capable of sequentially grabbing the carrier plates on the conveying belt and arranging the carrier plates in a layered mode, and can also carry the grabbed layered carrier plates at the same time and place the carrier plates on a multi-layer carrier plate temporary storage frame located on the top of the multi-carrier-plate temporary storage lifting device. The multi-carrier-plate output device is
