[0001] The utility model relates to a loading and unloading technology of a PCB board, in particular to a synchronous loading and unloading device for a plurality of PCB boards. [Background technology]

[0002] With the demand for miniaturization and lightweight of electronic products, the PCB boards used in electronic products are getting thinner and thinner. Therefore, the PCB boards need to be placed in a carrier for positioning and support before subsequent processing. This requires the use of a large number of specialized machines and equipment to process and assemble PCB boards, especially in the process of loading and unloading PCB boards. A large number of board loaders or board feeders are needed to facilitate the automatic loading and unloading of PCB boards.

Therefore, in the automated production process, for the control of synchronous loading and unloading of multiple materials, it is urgent to develop a loading and unloading device with a simple structure and easy use for synchronous control of multiple PCB boards.
