Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for checking the continuity of a large number of terminal pins in electrical components (printed circuit boards, etc.) K constituting electronic devices such as electronic computers, electronic exchanges, or control panels. This invention relates to an automatic tube attachment device used to attach insulating tubes to power supply pins.

FIG. 1 is a side view of electrical components constituting an electronic device.

In the figure, 1 and 3 are printed wiring boards, respectively.
2 is a connector. That is, the printed wiring boards 3 and 1 are connected through the connector 2, and the edge pattern of the printed wiring board 3 is used as a male contact, and the leaf spring or the like on the connector 2 side is used as a female contact to connect them.

On the other hand, the printed wiring boards 3 and 1 are connected by inserting a large number of pins P of the connector 2 into through holes of the printed wiring board l as shown.

Now, in this electrical component, signal pins and power supply pins are included in the numerous pins P protruding from the through holes of the printed wiring board 1. In the inspection process of electronic equipment,
The presence or absence of continuity between each signal bin and signal pin is checked to see if it is as specified, but if the signal bin and power supply bin are mistakenly connected during the check, a short circuit will occur. Therefore, an insulating tube is usually attached to the power supply bottle to prevent a short circuit from occurring even if the power supply pin and the signal bottle come into contact with each other before starting the above-mentioned check operation.

Attaching insulating tubes to power pins is done manually using tubes made of soft resin such as Teflon or vinyl, but when actually attaching them, the tubes sometimes get bent and cannot be attached properly. , or even if it was successfully installed, the VC required a relatively large amount of force to install it. For this purpose, a concave pipe K with one end closed and an insulating tube cut to a certain size in advance are loaded, and the insulating tube is press-fitted onto the pin by pressing the pipe against the power bottle by hand. However, such manual work has the problem of causing the tube to fall out if the pipe hole is inadvertently turned downward while carrying the loaded pipe to the power supply bin, so extreme care must be taken. The disadvantage is that it requires a lot of time and effort.

The present invention has been made to overcome the drawbacks of the prior art as mentioned above, and therefore an object of the present invention is to cut a continuous insulating tube to a certain size and cut it to save manual labor. An object of the present invention is to provide an automatic tube mounting device capable of automatically mounting the tube to nine power supply pins.

The main points of the configuration of the present invention are that the tube holding member is provided with a guide groove that guides the tip of the insulating tube toward the tip of the bottle in the pin arrangement, and that the tube tip is placed in a first position in the guide groove of the tube holding member. a tube guide means for guiding the tube from the tip to a second position and returning to the position in Part 1; and a cutting device for cutting the tube by a predetermined length from the tip when the tube tip is in the second position. means on a base, and when the tube is cut by a predetermined length from the tip, the base is driven by the driving means toward the pin array, and the cut tube is moved to a predetermined position by driving the base toward the pin arrangement. The main feature is that the base can be returned to its original position after being attached to the bottle.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a front view for explaining the principle of an embodiment of the present invention;
Figure 3 is the same plan view, Figure 4A is the line x-x in Figure 2.
FIG. 4B is a sectional view taken along @YY' in FIG. 2 and seen in the direction of the arrow.

First, refer to FIG. Cylinder 11 installed on base lO
is fixed. The slide base 12 is connected to the piston of the mounting cylinder 11 via a joint plate 13. Therefore, when the piston reciprocates in the cylinder 11, the slide base 12 also reciprocates toward the power pin P accordingly. A first clamp cylinder 15 and a cut cylinder 14 are mounted on the slide base 12. Further, a tube holding plate 18 is attached to the slide base 12, and a hollow groove is formed in the horizontal direction in this holding plate 18, and an insulating tube 19 is inserted into this groove. ing.

The arrangement relationship between the cylinders 14, 15 and the tube holding plate 18 is clearly shown in the plan view of figure M3.

As can be seen from Figure JI3, the second clamp cylinder 16 is arranged on the back side of the tube holding plate 18. This cylinder 16 is connected to a piston of a feed cylinder 17 (the feed cylinder 17 is not shown in FIG. 2 for simplicity). Therefore, if the piston moves back and forth in the feed cylinder 17, then! ! 2 clamp cylinder 16 also t
It reciprocates left and right along the Yup holding plate 18.

See Figure 4A. When the first crank cylinder 15 is driven, the clamp pad 2o attached to the tip of the piston holds the insulating tube 7'19 to the holding plate 1.
It can be clamped by pressing it against the back side of the groove No.8.

When the drive is released, the pad 20 also recovers and the tube 19
The clamp is also released. The second clamp cylinder 16 also functions in a similar manner.

See Figure 4B. When the cut cylinder 14 is driven, the cutter 2 attached to the tip of its piston
1, cut the insulating tube 19 as shown in the figure. When the body 4v is released, the cutter 21 is also restored.

Fig. 5 (A) is an explanatory diagram showing the arrangement when the second clamp cylinder 16 is in the feed 1 position, and Fig. 5 (←) is an explanatory diagram showing the arrangement when the second clamp cylinder 16 is in the second position. , is.

The operation of the automatic tube mounting device according to the present invention will be described with reference to FIG. 5 as well.

First, in FIG. 2, the base 10 is moved along the X-axis and Y-axis directions perpendicular to each other on a plane by means not shown, and positioned so that the insertion groove of the insulating tube 19 faces a predetermined power supply pin. do. Next, the second clamp cylinder 16 in the first position as shown in FIG.
The insulating tube 19 is clamped in the same manner as shown for the Ml clamp cylinder 15 in FIG. 4A. At this time, the first cylinder 15 does not clamp the insulating tube 19. In this state, feed cylinder 17 (see Figure 3)
is operated to move the second clamp cylinder 16 to the second position as shown in FIG. 5(B).

Since the insulating tube 19 is also clamped by the cylinder 16, it moves together with the cylinder 16 to reach the illustrated position. At this point, the first clamp cylinder 15 is driven to clamp the insulating tube 19 and fixed so that it does not move. Next, the cut cylinder 14 is driven as shown in FIG. 4B,
The tube 19 is cut with a cutter 21. Then, in the second M in this state, the mounting cylinder 11 is operated to drive the slide pace 12 toward the power supply pin.

Therefore, the tip of the insulating tube 19 is fitted into the tip of the power supply pin. At this time, since the rear end of the cut tube is supported by the surface of the cutter 21, its tip can be successfully pushed into the tip of the power supply pin. Once the mounting is completed, the mounting cylinder 11 returns to its original position.

Also, in Figure tJ5 (b), the second clamp cylinder 1
6 unclamps the tube 19 and moves the feed cylinder 17
It returns to its original position with the recovery operation. In other words, Figure 5 (
b) Return to the initial state as shown in K. By repeating the above operations, the insulating tube can be automatically attached to the power pin many times.

In the above, when the tip of the cut insulating tube is press-fitted into the tip of the power supply pin, if a mounting bit is used, the press-fitting operation proceeds smoothly. This will be explained below with reference to FIG.

FIG. 6 is a sectional view showing the structure of the mounting bit.

In the figure, the installation bit 22 is a hollow pipe-shaped tool, and is attached to the tip of the tube holding plate 18 so that its hollow portion coincides with the groove through which the insulating tube is inserted. The tip and rear ends of the bit 22 are each tapered inward, making it easy to insert the power pin P from the tip and the insulating tube 19 from the rear end. In addition, if a part of the bit 22 is broken and the other end of the leaf spring 23, which has one end fixed to the tube holding plate 18, is guided from the broken part into the inside of the bit and elastically presses the insulating tube 19, the power pin When the tip of P is press-fitted into the hollow part of the insulating tube 19, the press-fitting operation becomes smooth.

As described above, according to the present invention, since a means for feeding the insulating tube by a certain amount and cutting it to a fixed length is provided, it is possible to eliminate the variation in the length of the insulating tube cut by hand, and at the same time, it is possible to eliminate the variation in the length of the insulating tube cut by hand. By installing it in an automatic tube placement machine, it becomes possible to automate the machine using NC (numerical control), eliminating problems such as poor placement and incorrect placement of the tube, which previously were caused by manual work. It has the advantage of being able to continuously achieve correct attachment in a short period of time and achieving high efficiency.
