BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a triangular prism side surface printing jig and a triangular column side surface printing method, and in particular, a printing material such as an adhesive or an electrode material is printed on the side surface of a triangular prism vibrating body used in a vibrating gyro. In this case, the present invention relates to a triangular prism side surface printing jig and a triangular column side surface printing method.

[0002]

2. Description of the Related Art Generally, when a side surface of a triangular prism vibrating body used in a vibrating gyro is subjected to printing or the like, it is necessary to reverse the vibrating body. In the conventional triangular prism inversion method, as shown in FIGS. 14 to 16, the triangular prism (vibration body) 70 is inverted by combining the triangular prism fixing jig 50 and the triangular prism inversion jig 60.

Of these, the triangular prism fixing jig 50 includes an elongated substrate 51, and the substrate 5 is provided at both ends in the width direction of the substrate 51.
1, protruding in a direction orthogonal to 1 and each having a strip-shaped convex portion 5
2a and 52b are formed, and a plurality of triangular prism holding portions 53a and 53b are formed on the convex portions 52a and 52b, respectively.
The triangular prism holding portions 53a and 53b are formed by substantially V-shaped grooves having an angle of 60 ° so as to reach from one end in the width direction of the convex portions 52a and 52b to the other end. The plurality of triangular prism holding portions 53a and the plurality of triangular prism holding portions 53b are respectively formed at corresponding positions, and the pair of triangular prism holding portions 53a and 53b are arranged in a straight line.

On the other hand, the triangular prism reversing jig 60 includes an elongated flat plate 61, and plate-shaped portions 62a and 62b are formed at both ends in the width direction of the flat plate 61 in a direction orthogonal to the flat plate 61.
Further, a plurality of hook-shaped portions 63a and 63b are formed at the ends of the plate-shaped portions 62a and 62b, respectively, extending in the same direction as the plate-shaped portions 62a and 62b. The plurality of hook-shaped portions 63a, 63b formed in the width direction of the flat plate 61 are formed at positions corresponding to the hook-shaped portions 63a, 63b, respectively.
3b are arranged in a straight line when viewed in the width direction of the flat plate 61.

Hook-like portions 63a and 6 of the triangular prism reversing jig 60.
3b includes a rod-shaped portion 65. The rod-shaped portion 65 is the plate-shaped portion 62.
It is formed in a direction orthogonal to the longitudinal direction of a and 62b. An inclined portion 66 is formed in a substantially triangular shape at the tip of the rod-shaped portion 65. The inclined portion 66 includes an inclined portion 67, and the inclined portion 6
7, the angle a formed with the longitudinal direction of the flat plate 61 is 20 ° to 30
It is formed so that it becomes °.

The triangular prism reversing jig 60 is a triangular prism fixing jig 50.
Each of the triangular prisms 70 is held by the corresponding triangular prism holding portions 53a and 53b of the triangular prism fixing jig 50. At this time, the triangular prism holding portions 53a and 53b and the hook-shaped portions 62a and 62b are alternately arranged. The triangular prism reversing jig 60 is movable in the longitudinal direction of the triangular prism reversing jig 60, as indicated by an arrow G.

Next, the principle of operation and the method of operation in the above configuration will be described. First, as shown in FIG.
The triangular prism 70 is held by the triangular prism holders 53 a and 53 b of the triangular prism fixing jig 50, and the triangular prism reversing jig 60 is combined with the triangular prism fixing jig 50. Then, as shown by the arrow H,
The triangular prism reversing jig 60 is moved toward the tip of the hook-shaped parts 63a and 63b, that is, from one slope side of the triangular prism holding parts 63a and 63b toward the other slope side.

Then, as shown in FIG. 18, the inclined portion 66
Due to the slanted portion 67 of the
When a is pressed, as shown by the arrow I, the triangular prism 70 rotates in the direction in which the inclined portion 66 approaches. At this time, the side 72a connecting the apex 71a of the triangular prism 70 and the apex 71b tilted toward the inclined portion 66 side contacts the inclined portion 67. Then, as the inclined portion 66 moves, the triangular prism 70 slides up on the inclined portion 67.

Further, when the triangular prism reversing jig 60 is moved in the direction of arrow H, the triangular prism 70 is moved as shown in FIG.
Are extruded from the triangular prism holding portions 53a and 53b. Then, the apex 71c of the triangular prism 70 faces upward,
The side 72 a of the triangular prism 70 is the convex portion 52 of the triangular prism fixing jig 50.
The triangular prism 70 comes into contact with the upper sides of the a and 52b, and is placed on the convex portions 52a and 52b. Therefore, in the state shown in FIG. 19, the triangular prism 70 is inverted by 60 ° as compared with the state shown in FIG.

Next, as shown by an arrow J in FIG. 20, the triangular prism reversing jig 60 is moved in the horizontal direction opposite to the arrow H, that is, from the other slope of the triangular prism holders 53a and 53b toward one slope. Let Then, the bar-shaped portions 65 of the hook-shaped portions 63a and 63b adjacent to the hook-shaped portions 63a and 63b that pushed out the triangular pillar 70 push the triangular pillar 70 in the direction of the arrow J. Then, the triangular prism 70 is dropped and held so that the sides 72a and 72b contact the triangular prism holding portions 53a and 53b. Therefore, in the state shown in FIG. 20, the triangular prism is inverted by 60 ° as compared with the state shown in FIG.

As shown in FIG. 17, the vertex 71a faces downward before the triangular prism 70 is inverted, and the vertex 71b faces downward after the triangular prism 70 is inverted, as shown in FIG. There is. In this way, the triangular prism 70 is fixed to 12 by using the triangular prism fixing jig 50 and the triangular prism reversing jig 60.

A plurality of triangular prisms 70 are held by 53b. The print pattern 75 is formed on the side surface 77a of the triangular prism 70 that faces upward.
A printing material (not shown) such as an adhesive material or an electrode material is printed by the squeegee blade 76. Here, the triangular prism 70 was inverted using the above-mentioned triangular prism inversion method, and the printing material was printed on the other side surfaces 77b and 77c of the triangular prism 70.

[0013]

However, in such a triangular prism side surface printing method, since the triangular prism reversing jig 60 covers the triangular prism 70, the printing material is applied to the side surfaces 77a, 77b, 77c of the triangular prism 70. At the time of printing, it was necessary to remove the triangular prism reversing jig 60, and the workability was poor. Further, since the triangular prism fixing jig 50 is fixed to the printed board 73, the triangular prism 70 should be carefully positioned while
They had to be held one by one in the triangular prism holders 53a and 53b. Therefore, the time required for the setup work is increased, resulting in a decrease in work efficiency.

Therefore, the main object of the present invention is to remove the triangular prism reversing jig when printing the printing material on the side surface of the triangular prism, and to transfer the triangular prism fixing jig while holding the triangular prism. It is an object of the present invention to provide a triangular prism side surface printing jig and a triangular prism side surface printing method in which the positioning of the triangular prism can be facilitated and the working time can be shortened to reduce the processing cost.
