The existing cache machine has a limited temporary storage capacity and cannot cache a large number of PCB boards at one time. If the number of cache layers of the PCB board is simply increased, the height of the cache machine will increase, and the structure will be complex, which will require a high load capacity of the drive mechanism, affecting the operating accuracy and increasing the risk of PCB board damage.
