Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for effectively creating electronic component mounting position data necessary for an electronic component mounting apparatus that mounts electronic components on a printed circuit board.

BACKGROUND ART An example of a conventional technique for creating electronic component mounting position data from a printed circuit board will be described below with reference to the drawings.

FIG. 3 is an external view of a conventional data creation machine.

In Fig. 3, 4 is a handle for moving in the X-axis direction, and 5 is a handle for moving in the Y-axis direction.
A handle for moving in the axial direction, 6 a camera, 7 a board setting table, 8 a TV monitor that does not show the board, and 9 a computer.

First, the data creator places and fixes the printed circuit board for the data he/she wants to create on the board installation table 7.
A cross cursor 10 as shown in FIG.
1, and visually align the center of the crosshair cursor on the TV monitor to the position where the electronic component will be mounted on the printed circuit board using the handles 4.5 for moving in the X-axis direction and in the Y-axis direction. This visually matched position information is sent to the computer to create mounting position data.

Problems to be Solved by the Invention However, although the above method can create mounting position data, the nozzle constraint conditions when mounting electronic components with a mounting machine and the minimum required area when opening and closing the chuck are
Since the LU data is not set, when the parts are actually mounted using the mounting machine, the already mounted parts get in the way and the next part cannot be mounted, so the data is created again. There will be work to do again. For this reason, there is a problem in that it takes a lot of time to create one piece of mounting data.

The present invention solves the above problem, and in order to shorten the time required to create data, the computer contains machine-specific information such as the nozzle information of the electronic component mounting machine and the minimum required area when opening and closing the chuck. By displaying this information on the TV monitor to alert the user when reading the component mounting position, it is now possible to create mounting data that allows parts to be reliably mounted at once, making it possible to create data efficiently and in a short time. The purpose of this invention is to provide a method for reading printed circuit board coordinates.

Means for Solving the Problems In order to solve the above problems, the printed circuit board mounting position data reading method of the present invention reads electronic component mounting position data including construction method conditions from an actual board. The first step is to memorize information specific to the component and the mounting machine, the second step is to place the printed circuit board on the mounting position data reading device, and the cursor corresponding to the information is displayed on the TV monitor, and the manual or The method consists of a third step in which the camera is automatically moved to match the position on the board where the electronic component is to be mounted, and a fourth step in which the mounting position is read using the cursor, taking at least information specific to the mounting machine into consideration.

Effect With the above-mentioned configuration, by displaying a cursor for adjacency check on the TV monitor based on information stored in the computer in advance, it is possible to read the component mounting position by taking into account the information specific to the mounting machine when mounting the component. This eliminates the need for the conventional wasteful work process of actually mounting the components with a mounting machine, checking the data, and correcting any defects. It becomes possible to create.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing a cursor displayed on a TV monitor showing a printed circuit board when reading the electronic component mounting machine 2 according to the present invention. In FIG. 2, 1 indicates an adjacent parts prohibition cursor, 2 indicates a part shape cursor, and 3 indicates a cross cursor.

FIG. 1 is a flowchart showing a procedure for creating electronic component mounting position data according to the present invention. In Figure 1, first, it is checked whether data regarding the component to be mounted or the mounting machine used for component mounting currently exists in the database inside the computer (step 1); if the corresponding data does not exist in the database, , register the necessary data in the database (step 2). Next, by registering the name of the component to be mounted, the cross cursor 3, component shape cursor 2, and adjacent component prohibition cursor 1 are displayed on the TV monitor (step 3).Next, the component mounting position on the printed circuit board is Align with the cross cursor 3 or part shape cursor 2 on the monitor (step 4), and import the position data into the computer (step 5). Repeat steps 3 to 5 while considering the mounting order using the adjacent component prohibition cursor 1, and then
'l device data will be created.

Note that the method for aligning the component mounting position on the printed circuit board on the 'I' V monitor may be performed manually or automatically. Further, the cross cursor 3, the component shape cursor 2, and the adjacent component prohibition cursor 1 may be configured so that only necessary cursors can be displayed when necessary.

Effects of the Invention As described above, according to the present invention, a cursor for checking adjacent parts can be displayed on the TV monitor by storing component data and mounting machine data as a database inside the computer, and it is possible to actually check data with the mounting machine. Therefore, the process of mounting and checking the components becomes unnecessary, and it becomes possible to create electronic component mounting position data in a short time and efficiently.
