And after the front feeding and board loading program is started, the working modes of the main clamp and the auxiliary clamp are selected. If yes, loading and loading the board program after starting; and starting a back feeding and plate loading program, and placing the plate by manual front feeding and by back feeding of a feeding device. And after the loading and board loading program is started, the working modes of the main clamp and the auxiliary clamp are selected.

If not, the process that the material pushing device pushes the material to the clamping initial position of the tool holder does not interfere with the clamping initial position of the main tool holder, and the material pushing device pushes the material to the clamping initial position of the tool holder.

If the position is the same as the initial position of the clamping material of the clamping tool, the process of pushing the material by the material pushing device to the initial position of the clamping material of the clamping tool interferes with the clamping material feeding device of the main tool, and then the clamping material feeding device of the main tool is judged to feed or avoid.
