Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component insertion device for automatically inserting a component to be inserted such as an electric component into an insertion target such as a printed board.

[0002]

2. Description of the Related Art A conventional component insertion apparatus for automatically inserting terminals of an electrical component into a wiring board such as a printed board holds an electrical component between chuck fingers composed of a pair of opposed finger portions and the state thereof is maintained. Push the electric component with the pusher to insert the terminal of the electric component into the wiring board. Figure 3
FIG. 3 is a side view showing the structure of an example of the component insertion hand 1 disclosed in JP-A-6-39651 and the like. The chuck fingers composed of the first finger portion 11 and the second finger portion 12 move in the clamping direction indicated by the arrows to clamp the upper side surface of the electric component 2 with the component clamping surfaces 111 and 121, and the both finger portions 11 The pusher 13 disposed in the gap between the electric components 2 and 12 presses the upper surface of the electric component 2 in the pressing direction indicated by the arrow in the upper part of FIG. 3, and moves the electric component 2 in the insertion direction indicated by the arrow in the lower part. Then, the terminals of the electric component 2 are inserted into the terminal holes of the wiring board (not shown). The electric component 2 moves when the pressing force of the pusher 13 becomes larger than the frictional force due to the force that the fingers 11 and 12 clamp the electric component 2. The gripping force of both fingers 11 and 12 is adjusted as necessary. The pushing force of the pusher 13 is given by a pushing force drive mechanism such as an air cylinder.

[0003]

In such a conventional component insertion device, the size of the electric component 2 is different from that of the pusher 13.
When the size is smaller than the size, the electric parts 2 cannot be held between the finger portions 11 and 12. In such a case, if the pusher 13 is not arranged between the fingers 11 and 12 but is arranged on both sides of the fingers 11 and 12, the small electric component 2 can be sandwiched. Become. However, since the number of components including the pushing force drive mechanism such as the air cylinder is large and the overall configuration is large, the cost of the equipment is high, and further, another component arranged near the electric component 2 to be inserted is required. There is also a problem that it is easy to interfere with electric parts and it is difficult to increase the density of electric parts that can be arranged.

An object of the present invention is to solve the above-mentioned problems and to securely hold a plurality of external components including small-sized components to be inserted and to insert the components at high density in a small size and at a low cost. An object is to provide a component insertion chuck finger of a component insertion device.

[0005]

According to a first aspect of the present invention, there is provided a component insertion chuck finger of a component insertion device for sandwiching a component to be inserted and inserting the inserted component into an insertion target.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a component insertion chuck finger of a component insertion device according to the present invention will be described with reference to examples. It should be noted that parts having the same functions as those in the prior art are designated by the same reference numerals. 1 and 2 show a structure and a usage state of an embodiment of a component insertion chuck finger 3 of a component insertion device according to the present invention, (a) is a side view, (b) is a plan view from above, and (c). ) Is a plan view from below. Figure 1
3 shows a state in which the same electric component 2 as that in FIG. 3 for explaining the conventional technique is sandwiched, and FIG. 2 shows a state in which an upper pin 21 of an electrical component 2a having a plurality of pins on the upper and lower sides is sandwiched.

Component insertion chuck finger 3 of this embodiment
Is composed of a pair of finger portions, a first finger portion 31 and a second finger portion 32. Component holding surfaces 311 and 321 are formed at the tips of the finger portions 31 and 32 so as to face each other, and can be fitted to each other above the upper ends of the component holding surfaces 311 and 321. In each state, the protrusions (in FIG. 1 and FIG. 2, referred to as insertion protrusions, hereinafter referred to as insertion protrusions) 312 and 322 and the escape grooves 314 and
And 324 are formed. The insertion protrusions 312 and 322 project from the component holding surfaces 311 and 321 by, for example, 1 mm, and the clearance grooves 314 and 324 are the component holding surfaces 311 and 321.
For example, each is engraved with 1 mm. The lower surfaces of such insertion protrusions 312 and 322 serve as component pressing surfaces 313 and 323 for pressing the upper ends of the insertion components while the insertion components are sandwiched by the component clamping surfaces 311 and 321.

In the state shown in FIG. 1, the first finger portion 31 and the second finger portion 32 are arranged in the sandwiching direction shown by the arrow in the central portion of FIG.
By moving both or either
The upper part of the side surface of the electric component 2 is clamped by the component clamping surfaces 311 and 321, and the component pressing surfaces 313 and
The 323 is in contact. In this state, when the component insertion chuck finger 3 is moved in the insertion direction shown by the arrow in the lower part of FIG.
Since they are held by 3 and 323, the electric component 2 does not slide upward in the component insertion chuck fingers 3 and is inserted into an unillustrated insertion target (for example, a printed board).

In the state shown in FIG. 2, the upper pin 21 of the electric component 2a having a plurality of upper and lower pins is attached to the component insertion chuck finger 3.
It is shown that the electric component 2a is held by a thin upper pin 21 (for example, 0.6 × 0.6 mm ² ). In this case, the gap between the component holding surface 311 of the first finger portion 31 and the component holding surface 321 of the second finger portion 32 becomes the thickness of the upper pin 21, so that the insertion of the first finger portion 31 is performed. The projection 312 for insertion enters the clearance groove 324 of the second finger 32, and the projection 322 for insertion of the second finger 32 enters the clearance groove 314 of the first finger 31, as shown in FIG. It is in the state shown in. When the upper pin 21 is clamped as shown in FIG.
Since it is necessary for 323 to contact the tip of the upper pin 21, it is necessary to select the arrangement position, width and number of the insertion projections 312 and 322. In the case of the embodiment, two insertion protrusions 312 and three clearance grooves 314 are formed on the first finger portion 31, and three insertion protrusions 322 and two clearance grooves 324 are formed on the second finger portion 32. And are formed.

In the above embodiment, the case where two different kinds of electric parts 2 and 2a are sandwiched is shown, but the inserted parts to which this embodiment is applicable are not limited to the electric parts, and the electric parts are not limited thereto. It goes without saying that this embodiment is just as effective in the case of other inserted parts. In order to securely and stably clamp the inserted component such as the electric component 2 or 2a, the component clamping surfaces 311 and 32
It is effective to apply anti-slip processing such as knurling or anti-slip processing such as urethane coating to 1.

Further, in this embodiment, the insertion projection
Although 312 and 322 are formed from the upper ends of the component holding surfaces 311 and 321 to the entire height of the fingers 31 and 32, it is not always necessary to form the insertion protrusions 312 and 322 to the upper ends, and the component holding surfaces are held. It may be formed only in the vicinity of the upper ends of the surfaces 311 and 321. As is clear from the above explanation,
By using this embodiment, in addition to the components that can be inserted by the conventional technique, it is also possible to insert smaller components or pins of the components by sandwiching them. Moreover, the insertion projection 312 and
Since the 322 prevents the inserted component from moving upward, the inserted component can be inserted into the insertion target by the movement of the component insertion chuck finger, and the pusher and the pusher for moving the inserted component in the chuck finger. A drive mechanism is not required, the device can be downsized, and interference with another inserted component disposed in the vicinity is reduced.

In the above embodiment, the component holding surface 311 of the first finger portion 31 and the component holding surface 321 of the second finger portion 32.
In order to reduce the distance between the two, the escape grooves 314 and 324 are formed respectively, but depending on the size of the smallest component to be sandwiched, the height of the insertion protrusions 312 and 322 may be, for example,
When forming the insertion protrusions 312 and 322 facing each other, it is slightly smaller than one half of the minimum component width, or when forming the insertion protrusions 312 and 322 without facing each other, it is smaller than the minimum component width. It is also possible to eliminate the formation of the escape grooves 314 and 324 by making them small.

[0015]

According to the first aspect of the present invention, the pair of fingers which face each other and move in the opposite direction are provided with the component holding surface and the component pressing surface. It is possible to insert a component to be inserted into the object to be inserted by gripping the grip and moving the pair of fingers in that state. In addition to the chuck finger including the pair of fingers as in the prior art, the pusher and its drive mechanism are inserted. Does not need to be equipped.
Therefore, it is possible to provide the component insertion chuck finger of the component insertion device, which has a simple structure, is small in size, is inexpensive, and hardly interferes with another component to be inserted disposed in the vicinity.

According to the second aspect of the present invention, by providing the escape groove, it is possible to adjust the interval between the component holding surfaces of both fingers to an arbitrary interval. Therefore, the component insertion chuck finger according to the present invention is provided. The external size of the component is not limited, and it is possible to grasp a small component or a pin provided on the component.
