The application discloses a control method of fusion of a core veneer, a control system thereof, a fusion machine, and a storage device, and the control method of fusion of the core veneer is characterized by comprising the following steps of presetting characteristic information of a core veneer to be fused, wherein the characteristic information of the core veneer to be fused includes the totalnumber of products to be processed and the number of core veneers to be fused included in each product to be processed; when detecting that each core veneer to be fused is placed on the fusion workbench of the fusion machine, reading a foolproof code preset on the current core veneer to be fused; determining whether the current operation is correct according to the foolproof code; if so, countingonce when the number of readings is equal to the number of sheets, and ending this operation and proceeding to the next process when the total count is equal to the total number of products to be processed; and otherwise, alarming and suspending the current operation. In the above manner, the application can add a foolproof design to the lamination and fusion of the core veneers, and increase thecounting function of reading the number of foolproof codes, so as to ensure that the products to be processed can be switched only when there is no wrong lamination.
