Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component chuck device used in an automatic component insertion device, etc., which reliably chucks easily deformed components such as felt, which are difficult to position.
Moreover, accurate positioning can be performed.

Conventionally, a component chuck device used in an automatic component insertion device, etc. has a pair of chucks 1 and 2 attached to a chuck body 5 by pins 3 and 4, as shown in FIG. A pair of chucks 1 and 2 are rotatable around pins 3 and 4. A piston 6 is provided inside the chuck body 5, and the protrusions 1a and 2a of the chucks 1 and 2 are in contact with the tip of the piston 6. Compression springs 7 and 8 are interposed between the upper parts 1b and 2b of the chucks 1 and 2 and the chuck body 5, respectively. A regulating pin 9 is attached to the tip 5a of the chuck body 5.

Now, when air is introduced from the air inlet 10a of the chuck support block 10, the piston 6 descends due to the pressure and pushes the protrusions 1a and 2a downward. As a result, chucks 1 and 2 are compressed by compression springs 7 and 2, respectively.
8 is compressed and rotated clockwise and counterclockwise around pins 3 and 4, respectively. Then, when the air is released, the compressed springs 7 and 8 press the upper parts 1b and 2b of the chucks 1 and 2.
rotate counterclockwise and clockwise around pins 3 and 4, respectively, and the tips 1c and 2c of chucks 1 and 2
holds the part to be chucked between its outer parts.

However, with this conventional device, when chucking easily deformable parts such as felt, there is nothing in the direction perpendicular to the pair of chucks 1 and 2 to hold or press the part. Therefore, it was not possible to sufficiently correct misalignments in the supplied state of the parts to be checked, making accurate positioning difficult and often causing checking errors.

The present invention solves the above-mentioned conventional drawbacks and
- A device that corrects the position of parts that are chucked from both Y directions, and that can ensure reliable chucking and accurate positioning by providing needle-like protrusions on the chuck surfaces of a pair of opposing chucks that hold and press the parts. It provides:

As one embodiment of the present invention, a chuck device for a pad of a cassette tape will be described below with reference to FIGS. 2 to 6.

The pad of a cassette tape is used to press the tape against the head of a cassette tape recorder with a constant pressure, and is made of rectangular parallelepiped felt.

First, in FIGS. 2 and 3, a pair of opposing chucks 1 and 2 are rotatably attached to the chuck body 5 by pins 3 and 4, similar to the conventional device shown in FIG. The check 1,
A pair of needle-like protrusions 11 and 12 are provided at corresponding positions on the tips 1c and 2c of 2, respectively. Further, as shown in FIG.
A pair of opposing chucks 13 and 14 are rotatably attached to the chuck body 5 by pins 15 and 16. A piston 6 is provided inside the chuck body 5, and the protrusions 1a, 2a, 13 of the chucks 1, 2, 13, 14 are attached to the tip of the piston 6.
a and 14a are in contact with each other. Also, check 1,
2, 13, 14 upper part 1b, 2b, 13b, 14
Compression springs 7, 8, 17 and 18 are interposed between the chuck body 5 and the chuck body 5, respectively. A regulating pin 9 is attached to the tip 5a of the chuck body 5.

Next, the operation will be explained. When air is introduced from the air inlet 10a of the chuck support block 10, the piston 6 descends due to the pressure, and the protrusions 1a, 2a, 13 of the chucks 1, 2, 13, 14
Push a and 14a downward. As a result, the chucks 1, 2, 13, and 14 are compressed by the compression springs 7, 8, and 14, respectively.
17 and 18 are compressed, and chucks 1 and 13 are rotated clockwise and chucks 2 and 14 are rotated counterclockwise around pins 3, 4, 15, and 16, and in this state, chucks 1 and 14 are rotated against the pad. Tip 1 of 2, 13, 14
c, 2c, 13c, and 14c are fitted. Then, when the air is released, the compression springs 7, 8, 17, 18, which had been compressed until then, are released from the upper parts 1b, 2 of the chuck.
b, 13b, 14b, chuck 1, 13
counterclockwise around pins 3 and 15, respectively,
The chucks 2 and 14 rotate clockwise about pins 4 and 16, respectively. This will result in check 1
As shown in FIG. 5, the tips 13c and 14c of pads 3 and 14 abut against the regulating pin 9, which is formed slightly wider than the width between the opposing sides of the pad 19, and tighten the pad 19 very slightly. The position of chucks 1 and 2 is controlled by
As shown in FIG.
1 and 12 bite into pad 19 and this pad 1
Hold 9.

Note that the pad 19 is moved to the desired location while being held in the chuck, and air is again injected from the air inlet 10a there to rotate the chucks 1, 2, 13, and 14, and the pad 19 is held in place by the chuck. is released and the pad 19 is placed in a predetermined position.

As described above, according to the component chuck device of the present invention, two pairs of chucks are provided orthogonally to each other, and two pairs of chucks are provided orthogonally to each other.
A regulating pin provided in conjunction with a pair of chucks presses and holds a component such as a pad with one pair of chucks, and the other pair of chucks are placed along the outside of the pad to position and hold the component from both X and Y directions. Therefore, parts can be accurately supplied to predetermined positions without positional deviation. By providing needle-like projections on the component chuck surface of the chuck that presses and holds the component, the component will not be misaligned in the chuck state, and a reliable chuck state can be obtained.
