The input device 10 configured as described above is an improved X-Y coordinate measuring device having a normal coordinate data counter, and is equipped with a keyboard for performing predetermined input operations on the measuring device. It can be manufactured at low cost. Furthermore, since the X-Y coordinate measuring device 21 and the keyboard can be operated continuously while standing at the same position, the apparatus has excellent operability.

In FIG. 1, 50 is an electronic computer. This electronic computer 50 includes an initial data storage device 51 that stores in advance initial data specified by the station number and the model of the insertion spindle and electronic components used, and each input value inputted via the input device 10.

In this case, the arithmetic unit 52 also includes a comparator 56 for passing the X-Y coordinates and insertion direction of the inserted insertion spindle 1, an output device, etc. A conventional electronic computer 50 may be used.

In this embodiment, the cut-off data stored in the initial data storage device 51 uses the distance between the lead wires selected to specify the number of lead wires. This initial data is input from the initial data input device 54 (namely, the keyboard of the computer) and is stored in advance in the initial data storage device 51 for various inserted parts. Note that the station number and the insertion spindle to be used are also stored as search data at the same time.

The arithmetic unit 52 calculates the coordinate data color/reference 22 described above.
A predetermined calculation is performed based on the X-Y coordinate values and insertion conditions sent from the electronic component automatic insertion machine, and the axial operating position of the insertion spindle 1 of the automatic electronic component insertion machine, the amount of rotation of the spindle 10, etc. are output.

Here, the axial operating position of the insertion spindle 1 of the automatic electronic component insertion machine and the amount of rotation of the spindle 1 will be explained.

The number of lead wires is 1 as shown in Figure 6(a).
The electronic component is clamped by the clamping claws 6 with its lead wire positioned on the same straight line as the center of the insertion spindle 1.

Therefore, in this electronic component, the position where the center of the insertion spindle 1 is directly above the hole into which the lead wire is inserted becomes the axial operating position.

Further, in this electronic component, the insertion spindle 1 does not require rotation, and therefore, the amount of rotation is zero.

For electronic components with two lead wires as shown in FIGS. 6(b) and 6(d), the midpoint of the line connecting each lead wire is generally located on the same straight line as the center of the insertion spindle 1. It is held in a state of Therefore, in this electronic component, the position where the center of the insertion spindle 1 is directly above the midpoint of the straight line connecting the holes into which the lead wires are to be inserted is the axial operating position.

Further, the electronic component requires a rotation amount corresponding to the insertion angle.

Generally, for an electronic component having three lead wires as shown in FIG. 6(C), the midpoint of the virtual figure formed by connecting the lead wires is located on the same straight line as the center of the insertion spindle 1. It is held in a state of Therefore, in this electronic component, the position where the center of the insertion spindle 1 is directly above the midpoint of the virtual figure formed by connecting the holes into which the lead wires are to be inserted is the axial operating position. Further, the electronic component also requires a rotation amount corresponding to the insertion angle.

Axial operating position of the insertion spindle 1 and the same spindle 1
Since the amount of 0 rotation is as described above, the calculation device 52 can perform simple geometric calculation processing based on the X-Y coordinate values and insertion condition values and output these insertion data. can.

Note that in the calculation process, the distance between each lead wire is calculated, and the value of the distance between the lead wires is also output from the calculation device 1.

The comparison device 56 extracts and inputs the data of the corresponding electronic component from among the data on the distance between lead wires of various electronic components stored in the initial data storage device 51, and
The output from the arithmetic unit 52 is input. and,
The distance between lead wires data from the initial data storage device 51 is compared with the short end calculated value between the lead wires from the calculation device 52, and if the difference between these values is within a predetermined tolerance range, the calculation device The axial movement position of the insertion spindle 1 and the amount of rotation of the spindle 10 simultaneously fed out from f\52 are passed through. The system of the comparison device 56 and the initial data storage device #51 is a confirmation circuit for preventing input errors, and if the above-mentioned comparison value is outside the allowable range, the electronic computer 50 displays an input error. Display this on the device.

In the figure, numeral 55 is a data storage device, which temporarily stores the information that has passed through the comparison device 56. In order to create a program, it is necessary to obtain the axial movement position of the insertion spindle 1 and the amount of rotation of the spindle 1 for all inserted electronic components, so the data storage device 55 is used until the operation is completed. Let me remember it.

Reference numeral 56 in the figure is an output device, which stores the insertion data stored in the data storage device in a storage medium such as a pronovy disk or magnetic tape, and inputs it to the control device of the automatic electronic component insertion machine. Create a program body. - Note that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
