Electronic component mounting system with cross line communication
A component mounting system has a supply reel accommodating a component, a plurality of mounting lines each having a mounting apparatus and a line management apparatus, and a central network that provides direct communication between the line management apparatuses of each mounting line. A remaining number of components on the supply reel is determined based on cross line communication between the line management apparatuses and comparison of data at different times stored on the line management apparatuses. Such architecture does not require the use of a central server. Rather, the system is a material information exchange system without a single point of failure, where no one computer failure can cause an entire factory shutdown.
1. A component mounting system, comprising:
a supply reel configured to accommodate a component to be mounted to a substrate, the supply reel being associated with a reel identifier;
a plurality of mounting lines, each of the mounting lines comprising:
a plurality of mounting apparatuses configured to mount the component supplied by the supply reel on the substrate; and
a line management apparatus having a storage device that stores data associating with the reel identifier and a remaining number of components accommodated by the supply reel at a time point, and a processor configured to monitor the remaining number of components; and
a central network configured to provide direct communication between the line management apparatuses of each of the plurality of mounting lines, wherein:
when the supply reel is mounted to each of the plurality of mounting apparatuses in a first mounting line of the plurality of mounting lines, the processor of the line management apparatus of the first mounting line is configured to determine the remaining number of components accommodated by the supply reel based on stored data, and
the stored data is identified via communication between the line management apparatus of the first mounting line and the line management apparatus of one of the other mounting lines via cross line communication over the central network, and
wherein when the stored data that is associated with a most recent time point is stored on the line management apparatus of one of the other mounting lines, the stored data associating with the reel identifier and the remaining number of components accommodated by the supply reel at the most recent time point is copied from the line management apparatus of the one of the other mounting lines and replicated on the storage device of the line management apparatus of the first mounting line.
2. The component mounting system of claim 1 , wherein when the stored data is copied and replicated, an entry from which the stored data is replicated is marked as invalid.
3. The component mounting system of claim 1 , wherein when the supply reel still accommodates components and when the stored data associating with the reel identifier and the remaining number of components stored on the line management apparatus of the first mounting line indicates the remaining number of components is not greater than a predetermined value, the remaining number of components in the stored data on the line management apparatus of the first mounting line is updated to be a tolerance in number of components initially provided with the supply reel.
4. The component mounting system of claim 1 , wherein when no data associating with the reel identifier is stored on the line management apparatus of the first mounting line or line management apparatus of one of the other mounting lines, the line management apparatus of the first mounting line is configured to prompt a user to register the supply reel.
5. The component mounting system of claim 1 , wherein the supply reel is configured to accommodate a plurality of components on spliced carrier tapes.
6. The component mounting system of claim 1 , wherein the line management apparatuses of the plurality of mounting lines are configured to communicate directly over the central network without a centralized server.
7. The component mounting system of claim 1 , wherein the component is a surface mount electronic component.
8. The component mounting system of claim 1 , wherein when the stored data associating with the reel identifier on the line management apparatus of one of the other mounting lines indicates that the supply reel is presently mounted to a mounting apparatus of the one of the other mounting lines, the line management apparatus of the first mounting line or the line management apparatus of the one of the other mounting lines is configured to:
prompt a user to confirm which one of the mounting apparatuses the supply reel is mounted to, and
clear a memory of the mounting apparatus of the first mounting line and the mounting apparatus of the one of the other mounting lines.
