BACKGROUND With the development of the electronics industry, the use of automatic inserters for automatically inserting components into printed circuit boards (PCBs) on which various electronic components are mounted is increasing.

In order to insert components automatically in the electronic component inserter, information on the type, insertion position, and direction of the components is needed. Currently, most of the work is performed using CAD and computer equipment.

In order to produce printed circuit board (PCB) on the current CAD design drawing, the first design drawing is made as CAD, the artwork required for the production of printed circuit board is prepared with the designed drawing, and the drawing of the printed circuit board is CAD Write with.

Extracts information such as part number, location, direction, etc. from the printed circuit board drawing, and determines the specific type and quantity of parts to be used according to the separately drawn design drawing and based on this, BOM (Bill Of Material) ). The printed circuit board is produced from the CAD drawing of the printed circuit board thus prepared, and the parts are automatically or manually inserted therein to complete the printed circuit board.

In the above process, the numerical control data required for the automatic insertion has been produced manually by the computerized inferiority.

Due to this, waste of time and manpower is severe and there have been many problems in systematic management of data according to production.

Therefore, in the effort to create and manage the computerized CAD information, the optimal distribution method of such resources is widely used.

In general, auto-insertion is not a single device inserting all the parts, but divides the entire insertable part into several parts and distributes them in unique equipment.

Therefore, it is necessary to classify each component into an insertable component and a non-insertable component, and assign the component to each equipment.

In this case, it is absolutely important to increase productivity by making the time required for the insertion of the inserts to be uniform in all the equipments as much as possible so that one specific equipment takes more time than other equipments.

However, in order to equalize the insertion time of all the equipments as above, it is necessary to grasp the insertion time of each equipment, and to execute the insertion process for each printed circuit board and grasping the insertion time, it is troublesome to operate the insertion equipment. There is a problem that it takes a lot of time and time.

The present invention is to solve the above problems, an object of the present invention is to estimate the insertion time of the insertion equipment to assign the optimum parts to each equipment so that the small insertion time between the interpolation equipment compatible with each other It is to provide a magnetic insertion path creating apparatus having and a method thereof.

In order to achieve the above object, an apparatus according to the present invention includes input means for inputting various data such as component data and CAD data, and a component code of a component read from the component type database (KEY_NAME) by reading the component from the component list. To find out the type of parts, find the equipment that can insert the currently read parts in the insertable parts database (INSERT_P) and assign them as the inserting equipment of the current parts, and assign them to the current parts in the average insertion time database (MC_ST). Read the data about the insertion time, set the insertion time, perform the above process on all parts, add the total insertion time of the current part to the insertion time of the equipment to be inserted, add the sum of the insertion time of the current parts, and add the insertion time of each device. Interpolation time estimating means for storing the information, display means for receiving and displaying display data, and storing various data Displays a memory means and various functions on the display means, generates a data insertion path database from component data and CAD data inputted from the input means, and receives a selection command of the insertion time estimation function of the data insertion device. A main control unit for estimating the insertion time of the insertion device is operated by operating the insertion time estimation means.

In addition, the method according to the present invention reads the parts from the parts list, identifies the parts type by the parts code of the parts read from the parts type database (KEY_NAME), and the parts currently read from the self-insertable parts database (INSERT_P). Find the equipment that can insert and assign it as the insert equipment of the current part, set the insertion time by reading the insertion time data for the current part from the average insertion time database (MC_ST), and perform the above process for all parts. By adding the insertion time of the current component to the total insertion time of the equipment to be inserted, and adds, and stores the combined insertion time of each equipment.
