Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an NC punch device equipped with a punch die, and in particular, to protect the device by regulating the X and Y movement ranges. The present invention relates to an NC punch device suitable for punching holes in substrates and printed circuit boards.

[Background of the invention]

As a means of regulating the movement range, microswitches and
Limit switch, proximity switch.

There are optoelectronic switches, etc.

To install these devices, attach the Y-axis or Y@ sensor par 14.15 to the Y-axis or Y-axis moving part, as shown in the plan view in Figure 5 and the side view in Figure 6. synchronize with the X and Y movements, and then use the X-axis position detection switch 12 (sub) (rechargeable, etc.) or the Y@position detection switch
5(a) and (b) are fixed, and this fixed range ((
a) - (υ) only X.

Position detection switches 12 (a>(b), 15(a) and b) are installed to enable Y movement and to prevent the support frame 5 for the object to be drilled from hitting the die part 4 of the mold (in case of runaway, etc.) It is normal that

In the case of this method, the size of the die part 4 is all constant, the punch area of the object 1 to be drilled is constant, and the support frame 5 of the object to be drilled is
If the size is also constant, the position detection switch 12(a)(b
), 15(aXb) do not need to be fixed and moved, but if the size of the die 4 of the mold is different or the size of the punch area and the window (opening size) of the support frame 5 are different, the position detection switch 12 (a)(b), 15(a)i
) to determine the moving range of the X and Y axes.

For this reason, when replacing the punch die, if the combination of the die 4 size and object support frame 5 size (opening) of the die is different from the previously installed punch die, the position detection switch 12 (at(b), 15(a) and (b)), which was time-consuming.

The above example will be explained below.

Figures 7 and 8 show the die 4 size and range of movement. In the case of die 4 size increasing, as shown in Figure 7, it is possible to move in or out, but if die 4 size becomes D2 as shown in Figure 8, X, , X
This shows that the movement of 4 becomes possible and becomes larger compared to Xl and X2. Here, the range of this movement is support 5
The size within this frame is X, +f), +X2 or X, +X,
There will be ten mountains. From the above, even if the support frame 5 size is constant, die 4
If the size is different, the movable range is different, and the position of the position detection switch 12(a)(b)i5Cab> must be changed, resulting in poor workability.

Techniques in this field include, for example, the "Automation Design Handbook" published by Kogyo Kenkyukai Co., Ltd. in May 1975.

[Purpose of the invention]

The purpose of the present invention is to drive any type of punch type with a single touch, as a means of preventing runaway of the device drive when the punch type m types and die sizes are different. To provide an NC punching device capable of preventing runaway.

[Summary of the invention]

The feature of this invention is that the position detection sensor is attached so as to surround the die part of the punch type, and this enclosure is slightly inside the punch effective area (size within the support frame).
For this installation, a conductive material (such as a spring) is applied only to the part that corresponds to the die part of an insulated object, and a minute voltage (6 to 2
4V) is applied, and when the die part of the mold comes into contact with the position detection sensor, a current flows, which is detected and the drive is stopped.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

Figure 1 shows the entire punch die. Although this punch die is manufactured for each type of object to be drilled and the overall external size can be kept constant, the external size of the die 4 is , it varies depending on the board cutting and pitch size, and it is impossible to make it constant.

In order to perform a punching operation, it is necessary to set a punch mold in the NC corbel device as shown in FIG. At this time, it is necessary to remove arm 6(a) and take out and insert the punch die.

After setting the punch mold, arm 6(a) is attached, and insulating frame 24 having the same opening size as support frame 5 is attached to this (FIG. 6). This insulating frame 24 has a touch sensor 25 (
This touch sensor 25 is
Connect the signal gJ26 so that the signal can be taken and joint it to the NC punch and device control section.

The mold is made of metal, and the die part 4 of this mold is passed through 1If (
6-24V). Next, the object to be drilled is set on the support frame 5. This is done by placing the guide bin on the support frame 5.
A guide hole method in which a guide hole is drilled may be used, or a method in which the object 1 to be drilled is directly attached to the support frame 5 may be used. The support frame 5 on which the object 1 to be drilled is set is set on the arm part 6 of the NC punching device, and X, Y, and Z are operated under NC control to start drilling. At this time, due to a programming error or malfunction of the device, when the X and Y movements become large and the support frame 5 hits the die 4 part, the touch sensor 25 touches the die 4 part before the support frame 5 hits. Contact signal line 26
Turn the NC control gefj! A signal is sent to t to immediately stop the X and Y movements to prevent damage to the device such as damage to arm 6. As mentioned above, if you prepare the insulating frame 24 for the various valve sizes of the support frame 5 (however, it is possible to unify the size of the support frame 5 to some extent), the position detection and alignment can be done with one touch, which greatly improves work efficiency. Get better.

Another method is to set the movement range numerically and use it each time you move, but this has the disadvantage of slowing down the punching speed.

〔Effect of the invention〕

According to the present invention, it is possible to set the movement range with one touch even if the die size and support opening size of the mold are different, and it is possible to improve and simplify the work efficiency. In addition, in the conventional method, if there was a bend in the detection bar because the detection was based on external movement, the detection position would be different or the detection would be indirect, resulting in low reliability.However, according to the present invention, detection is performed at the minimum part of the movement range. Direct placement increases reliability.
