DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a device for creating chip mounter data necessary for automatically mounting chip components on a printed wiring board.

(Prior Art) Applying cream-like solder to the component mounting solder surface of the printed wiring board, and then arranging the required chip components in a predetermined position and heating, thereby automatically mounting the chip components. An automatic assembling position called a chip mounter that is designed to be used is widely used. As can be seen from the above description, in order to automatically mount a chip component using the chip mounter, it is necessary to provide the chip mounter with data for designating which component and how to place it.

Conventionally, in order to obtain this required data, a pattern diagram of the required solder surface of the printed wiring board is placed on the reading surface of the coordinate reading device, and the worker searches for the planned mounting position of the component from the pattern diagram, and plans to mount it. The operator visually determines the approximate center coordinates of the position, reads the approximate center coordinates with an appropriate coordinate reading device to create mounting data, and then actually uses the data obtained in this way to actually determine the chip mounter. A method has been used in which the operation is performed to check whether or not a problem occurs, and when the problem occurs, the work of correcting the mount data is repeated.

(Problems to be solved by the invention) Therefore, in the past, in order to create the data necessary for operating the chip mounter, enormous man-hours are required, the data creation cost is high, and the data correction is required. Requires a chip mounter test run, so
There is a problem that the operating rate of the chip mounter is reduced.

The chip mounter data creating apparatus 1 is composed of a type and arrangement information of each chip component mounted on a printed wiring board and is not shown in the related art. A device for creating input data for a chip mounter having a configuration, which is provided with a coordinate reading device 3 for reading coordinate data of required points in a pattern diagram 2 of a printed wiring board as shown in FIG. There is. In the illustrated embodiment, the coordinate reading device 3 is a free cursor type coordinate reading device having a free cursor 31, and the pattern drawing 2 shown in FIG. 2 is set on the coordinate reading surface 32 according to a predetermined procedure, and the free cursor is set. Three
1 can be used to output coordinate data indicating the coordinate value of an arbitrary point on the pattern diagram 2.

A menu area 33 is provided on a part of the coordinate reading surface 32. The menu area 33 is provided with a type table of chip components mounted on the printed wiring board, the type is selected by the free cursor 31, and the resulting type data K is output from the coordinate reading device 3. It is configured to be.

This coordinate reading device 3 has information for mounting the component of interest in the pattern set in FIG. 2 set for coordinate reading, that is, the coordinate data of the mounting center position of the component and the mounting angle indicating the mounting angle of the component. It is provided in order to obtain necessary coordinate data necessary for calculating data as described later. This required coordinate data is the coordinate data of the required four reference points of a set of printed figures for mounting the part of interest, and the reference points are shown in FIGS. 3 (a) to 3 (c). It will be described based on.

FIG. 3 (a) shows a set of printed figures for mounting two-terminal parts such as resistors, capacitors and diodes. This set of printed figures is composed of rectangular patterns A and B, and their reference points are the outermost corner points a, b, c, and d.

FIG. 3 (b) shows a set of printed graphics for mounting a three terminal component such as a transistor. This set of printed figures is made up of three square patterns C, D, E, and their reference points are the outermost corner points e, f, g, h.

FIG. 3 (c) shows a set of printed figures for mounting a multi-terminal component such as an integrated circuit. In this case, the reference points are also the four outermost corner points i, j, k. , L.

From the coordinate reading device 3, type data K indicating the type of the part of interest and a set of coordinate data D consisting of coordinate data of required reference points in a set of printed figures for mounting this part are provided. Is output. This set of coordinate data D is
Usually, coordinate data D ₁ , D ₂ , D ₃ , D of four reference points
Consists of _four, therefore, from the coordinate reading apparatus 3, so that five data _{K, D 1, D 2,} D 3, D 4 are sequentially output. The operator operates the free cursor 31 so that the output order is a predetermined order.

These data output from the coordinate reading device 3 are temporarily stored in the memory in the calculation unit 4. After that,
According to the calculation program preset in the calculation unit 4, the data D ₁ and D stored in the memory 41 are stored.
Mounting center position data M indicating the coordinates of the mounting center position of the part based on ₂ , D ₃ , and D ₄ , and mounting angle data S indicating the inclination with respect to the reference line when the part is mounted
Is calculated and output.

This calculation is, for example, in the case of the figure shown in FIG. 3 (a), X ₁ = (X _a + X _b + X _c + X _d ) × 1/4 Y ₁ = (Y _a + Y _b + Y _c + Y _d ). × 1/4 Here, X ₁ is the X coordinate value of the mounting center, X _{a to} X _d are the X coordinate values of the reference points a to d, Y ₁ is the Y coordinate value of the mounting center,
Y _{a to} Y _d are X coordinate values of the reference points a to d, and θ ₁ is a mounting angle.

Similarly, in the case of the figure shown in FIG. 3 (b), X ₁ = (X _e + X _f + X _g + X _h ) × 1/4 Y ₁ = (Y _e + Y _f + Y _g + Y _h ) × 1 / Four Here, X _{e to} X _h are X coordinate values of the reference points e to h,
Y _e to Y _h are Y coordinate values of the reference points e to h.

Further, in the case of the figure shown in FIG. 3 (c), the required calculation can be performed in exactly the same manner as in the case of FIG. 3 (a).

The data M and S are data containing the results of these calculations.

Note that the set of reference points shown in FIGS. 3 (a) to 3 (c) is an example, and the required data M and S cannot be obtained only by this set of reference points. , Third
It is apparent that the same calculation result can be obtained by using the points a ′, b ′, c ′, d ′ as a set of reference points in FIG. In some cases, each of the above-mentioned reference points may not be accurately read by the free cursor 31 due to the drawing out for wiring, but in such a case, it is possible to select an accurate reference point by selecting one set of the reference points. It is possible to obtain various center position data M and mounting angle data S.

Data M, S and K are output from the calculation unit 4, and these data M, S and K are generated by the data creation unit 5
At, the data is converted into input data in a required format for the chip mounter, and is output as data in a desired form at the output device 6. The data from the output device 6 may be in the form of being stored as magnetic data on a magnetic disk or in the form of data in which required data is printed and displayed on a sheet.

According to the above-described configuration, the coordinate reading device 3 only reads a predetermined reference point in the pattern diagram 2 to automatically calculate the mounting center position and the mounting angle of the required component.
The input data required to operate the chip mounter can be created automatically and accurately.

Although the structure for inputting the data of the type of the attachment part by using the menu function of the coordinate reading device is shown in the embodiment, an input device dedicated to inputting the type data may be separately provided.

(Effect of the Invention) According to the present invention, as described above, the input data necessary for operating the chip mounter can be automatically generated by simply reading the coordinate data of the predetermined reference point in the printed wiring pattern diagram with the coordinate reading device. Since it can be created accurately, the number of man-hours for creating data can be significantly reduced,
Also, since it does not require a trial run by the chip mounter,
It is possible to expect an increase in the operating rate of the chip mounter.
