After the circuit boards are arranged in sequence, they are slotted by the laser slotting machine on one side. After slotting, they fall off from one side of the conveyor belt and fall into the receiving component for receiving, thereby achieving the purpose of automatically replacing the circuit boards for slotting operations.
