Next, the operation of the apparatus configured as described above will be explained based on an example. First, the original plate I5 is set at a predetermined position on the base 11. After setting the original plate 15, the lock body 14a of the detection head 14 is inserted into the holes (not shown) at the origin positions Xo and Yo of the original plate 15, and the position data of the origin is transmitted to the position detection section 16X.

After the hole position data of each hole 15'a'' 15b, . . . , that is, the component mounting position data The component mounting order is edited according to the flow shown in Fig. 4. This editing is performed by starting the data related to the cassettes Z1 to Z3 of the 1st U'', that is, k component mounting position data Xk, Y.
After reading k (k=1.2, 3...k) from the storage device, the distance L = 5 is determined in order to obtain component mounting position data at the minimum distance from the origin positions Xo and YO.
2Xo )2+ (YkYo)2+ (k-1p2.
3. . . . k) are calculated, and the minimum value is determined by calculation. Then, the position data at the minimum distance determined is determined as the mounted component and a serial number is assigned to it. Next, a new distance L is created based on the position data Xk and Yk with serial numbers.
=, /(xk-Xkl)2 + (Yk-Ykl y
Calculate and find the component mounting position data at the minimum distance. Then, a serial number is assigned to the position data in order. Furthermore, based on the position data for which a serial number has been found, searching for the position data that is at the minimum distance from among the position data that has not yet been assigned a serial number, and assigning a serial number to it is sequentially repeated. In this way, the component mounting order is obtained and stored in the storage device.

Next, data relating to the second group of cassettes Z4 to Z6, that is, component mounting position data Xt and Yt are read out to calculate distances. In this case, the final position of the data related to the first group of cassettes is determined as the origin position of the second group.

The component mounting position data at the minimum distance from the origin position of the second group is calculated, and a serial number can be assigned to the position data Xt11Yt1. Position data X, Y with this serial number
Calculates the component mounting position data to be at the minimum distance based on , and sequentially calculates the distance in the same manner as in the case of the first group to obtain the component mounting order, and stores this in the storage device 37. . The same storage devices 35 and 37 may be used.

The reason for performing such calculation is to minimize the moving distance of the PC board 3 of the automatic component mounting machine. Third
Data related to subsequent cassettes can also be obtained using the same method as described above! The loading order is determined and stored in the storage device. Here, an example has been explained in which three groups of Zi are taken, but this number is not limited to three, and may be two or four, for example.

Once the parts mounting order of all the cassettes has been determined and memorized as described above, the contents of the memory are read out by the NC processor 33 and recorded on the NC tape, and stored in the storage device of the automatic parts mounting machine. It allows you to remember.

According to the device of the present invention as described above, the following various effects can be achieved.

(2) Since the component mounting order is determined by the calculation means, the mounting order determining work is greatly simplified compared to the conventional method, and this greatly contributes to automation and efficiency of this type of work.

■, You can input the hole position data of the original plate randomly.
Therefore, the hole positioning by the detection head and the means for inputting hole position data become easier than ever.

■In addition, since the component loading order is carried out for each adjacent cassette, the moving distance of the cassettes of the automatic component loading machine is reduced, which increases the component loading speed. Since the component mounting order is determined in descending order of distance for each cassette, there is an advantage that the distance traveled by the PC board of the automatic component mounting machine can be reduced.
