In general, for optimal production, industrial sites use a variety of equipment to build a production line to perform a series of tasks. To build these production lines, set up data with location information necessary to perform the work of these equipment. I need a step.

Equipments that require the setup of data with location information necessary for performing tasks are typical of Surface Mounting Device (SMD), Auto Insert Machine (AI), Computer Numerical Control (CNC), and Flying Probe (FP).

Hereinafter, an example of a production line requiring setup of work data including position information in order to perform a series of work will be described.

1 is a configuration diagram of a general SMT assembly line.

The production line, which assembles surface-mount components on a printed circuit board, consists of several types of devices.

Specifically, a substrate loader for supplying a printed circuit board to a line, a screen printer for applying solder paste onto a pattern before mounting a component, and a surface mount component are mounted on the substrate. Surface mounter to mount, Reflow Machine to connect the parts and patterns by melting the applied solder paste after mounting all parts on the substrate, and the mounting state It comprises a solder inspection (Solder Inspection), a sorter (Sorter) for sorting the printed circuit board is completed, and an unloader for removing the sorted board from the line.

Each equipment constituting the surface mounting line is connected via a conveyor, and the work boards having completed the work in each equipment are transferred to the next equipment through the conveyor.

Among the equipment constituting the surface mount line, the chip mounter is a surface mount assembly apparatus for mounting electronic components on a printed circuit board, and is used to mount electronic components such as various semiconductor devices. It is a device that is supplied from a component supplier and transferred to a mounting position of a printed circuit board, and then mounted at a designated position of the printed circuit board.

Each device constituting such a surface mounting line is not only used by any one manufacturer's equipment, the line may be composed of equipment of different manufacturers in consideration of various factors.
