BEST MODE FOR CARRYING OUT THE INVENTION
The preferred embodiment of the present invention will hereinafter be described in detail with reference to the accompanying drawings .
FIG. 1 shows an apparatus for an automatic mounting device for automatically inputting multiple component information according to an embodiment of the present invention. The apparatus for automatically inputting multiple component information includes a scanner 10, monitor 20, and a control section 50.
The scanner 10 takes an image of a bare printed circuit board on which no component is mounted and converts it into digital image data.
The monitor 20 displays the image data of the bare printed circuit board from the scanner 10 on a screen thereof . The input section 30 serves to input all kinds of data or commands by a user and includes a mouse 32 and a keyboard 34. The mouse 32 is clicked and inputs position information having a reference position coordinate and a mounting angle of respective desired components to be mounted. The keyboard 34 serves to inputs model information including a component number which indicates a kind of components to be mounted on the PCB.
The memory 40 stores a component list database (bill of material; BOM) which records information of components necessary in a mounting operation of the printed circuit board therein, and serves to store all databases or data necessary to mount components on the PCB therein.
The control section 50 calculates center coordinates (Cx, Cy) of the corresponding component to be mounted on the PCB from two reference position coordinates and the mounting angle of respective components clicked by the mouse based on the image of the PCB which is displayed on the monitor 20. The control section 50 searches component list database from component numbers of the corresponding components inputted by means of the keyboard 34. The component list database 42 stores model information having the numbers of respective components, component codes set to connect the corresponding components with reel information, information names which indicate the kinds of corresponding components, and component specifications of the corresponding components therein.
Accordingly, the control section 50 produces a database for a component mounting which includes the numbers of the corresponding components, component codes set to connect the corresponding components with the reel information, information names indicating the kinds of corresponding components, component specifications of the corresponding components, the center coordinates (Cx, Cy) of the corresponding components, and mounting orientation information with respect to respective components to be mounted on the PCB which is displayed on the monitor 20 and stores the database in the memory section 40. The control section 50 reads out equipment for component mounting according to a kind of respective components from information which is recorded in the component list database, produces numeral control data according to respective equipment and stores the numeral control data in the memory section, and outputs the numeral control data into corresponding equipment .
Hereinafter, an operation of the apparatus for an automatic mounting device for automatically inputting multiple component information according to the present invention is presented.
FIG. 2 is a flow chart for showing an input method using the apparatus for an automatic mounting device for automatically inputting multiple component information according to the present invention; FIG. 3 is a view for showing a component information input screen which is displayed on a monitor when automatically inputting component information by means of the apparatus for an automatic mounting device for automatically inputting multiple component information shown in FIG. 1; FIG. 4 is a view for showing an example of a method of setting reference points on the PCB which is displayed on a monitor when automatically inputting component information by means of the apparatus for an automatic mounting device for automatically inputting multiple component information shown in FIG. 1; FIGs. 5A, 5B, and 5C are views for illustrating methods for setting reference points of components to be mounted on the printed circuit board which is displayed on the monitor; and FIG. 6 is a view for illustrating a method for setting a mounting orientation of a component.
In step 110, as shown in FIG. 2, the scanner 10 reads out image data of a printed circuit board.
In step 120, the control section 50 receives the image data of the printed circuit board from the scanner, controls the monitor 20 to display the image data thereon, and controls the memory section 40 to store the image data therein .
In step 130, a user clicks the mouse 32 to input position information including reference .point coordinates of the printed circuit board and reference position coordinates and a mounting angle of respective components on the image of the printed circuit board which is displayed on the monitor 20.
With respect to step 130, respective input methods will now be described. i) the reference coordinates of the printed circuit board are inputted as follows. First and second PCB reference points 01 and 02 are set on the printed circuit board which is displayed on the monitor 20. The user controls a cursor to be placed at the first and second PCB reference points 01 and 02 on a screen and clicks the mouse 32 or inputs the keyboard 34. At this time, two corners which are located on a side of the printed circuit board may be set as the first and second PCB reference points 01 and 02. ii) Reference position coordinates of respective components to be mounted are inputted as follows. As shown in FIGs. 5A, 5B, and 5C, the user controls the mouse 32 to place the cursor at two reference points of the respective components and clicks the mouse 32. At this time, coordinates of two corresponding corners of a rectangle which encloses a corresponding component in a state that is circumscribed with the corresponding component are as the two reference points of the respective components. For example, FIG. 5A indicates a reference point of a component such as a resistor or a capacitor. FIG. 5B indicates reference point of a component such as an integrated circuit. FIG. 5C indicates reference point of a component such as a transistor. iii) Mounting angles of respective components to be mounted are inputted as follows. The mounting angles of respective components are relative mounting angles with respect to a predetermined reference axis of the printed circuit board. If a mounting angle of a component is a special angle such as 0, 90, 180, or 270, one of them is selected. If the mounting angle of the component is an angle other than the special angle, an arbitrary angle set button is selected and an angle which defines the component and an X axis is inputted.
In step 135, the user inputs a component number which indicates a kind of a component to be mounted on the printed circuit board by means of the keyboard 34.
In step 140, the control section 50 calculates center coordinates (Cx, Cy) from two reference position coordinates of respective components clicked by the mouse 32 on the basis of the image of the printed circuit board which is displayed on the monitor 20.
Regarding step 140, an example of a method for calculating the center coordinates of the respective components is illustrated in steps 141 and 142.
In step 141, as shown in FIG. 4, when the control section 50 receives the first and second PCB reference points 01 and 02 through the printed circuit board which is displayed on the monitor 20, a first direction of a straight line which simultaneously passes through the first and second PCB reference points 01 and 02 is set as an X axis, and a second direction which passes through the first PCB reference point 01 (Ox, Oy) and is perpendicular to the X axis is set as a Y axis.
In step 142, the inputted center coordinates of two reference points PI (XI, Yl) and P2(X2, Y2) of a component to be mounted on the printed circuit board, that is, relative center coordinate C(Cx, Cy) with respect to the reference point 01 (Ox, Oy) , are calculated equations which will be described below.
Cx = { (Xl-Ox) + (X2-Ox)}/2
Cy = { (Yl-Oy) + (Y2-0y) }/2
In step 145, the control section 50 searches a component list database 42 from a component number of a corresponding component inputted by the keyboard 34, and produces model information such as a component name which indicates the kind of corresponding component, a component code which is set in order to connect the corresponding component with reel information, and a specification of the corresponding component .
In step 150, the control section 50 produces a component mounting database 44 including information for the component number of the corresponding component, a component code for connecting the corresponding component with reel information, the specification of the corresponding component, center coordinates (Cx, Cy) , and the mounting orientation with respect to respective components to be mounted on the printed circuit board which is displayed on the monitor 20. And the control section 50 performs a function of storing the component mounting database 44 in the memory 40. A configuration of the component mounting database is as follows.

In step 160, the control section 50 determines equipment for mounting the respective component by using information recorded in the component mounting data 44, and produces numerical control data according to format of the respective equipment. The control section 50 outputs the numerical control data into corresponding equipment .
Therefore, the automatic mounting device can mount electronic component on the printed circuit board by means of the numerical control data outputted from the apparatus for automatically inputting the component information.
The present invention as described above provides an apparatus and a method capable of automatically inputting model and position information with respect to electronic component to be mounted in a device for mounting electronic components on a printed circuit board. Accordingly, measured values are accurate and consequently accuracy of control data is largely improved so that a printed circuit board is precision manufactured. Moreover, since the work is extremely simple, working time is reduced to thereby promote manufacturing efficiency.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
