Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a built-in device for automatically incorporating, for example, a dial into a timepiece mechanical body.

[0002]

2. Description of the Related Art Conventionally, in a device for automatically assembling a dial to a timepiece mechanical body, an assembling robot grips the dial and rotates it, and the rotating operation causes the dial to come into contact with a member. The positioning was performed, and then the dial was lowered and incorporated into the fitting groove of the timepiece mechanical body. And
The hitting member, which is the positioning means, is fixedly installed and always positioned at a fixed position to be incorporated.

[0003]

By the way, the one for always positioning the timepiece mechanical body at a fixed position is one which is subtly changed due to a machining error of the die of the timepiece mechanical body in the same process and is incorporated. The dial is not always installed at a predetermined position below the dial. If the assembled position of the timepiece machine body is slightly deviated from the predetermined position and there is an error, the dial comes into contact with the hitting member at the fixed position, so that the dial is lowered from the predetermined position in the predetermined direction as designed. Even
In some cases, this dial cannot be incorporated into the watch mechanical body.

Therefore, an object of the present invention is to install an embedded component such as a dial in accordance with the error even if the installation position of the embedded component such as a timepiece mechanical body is deviated from a predetermined position. It is to provide an automatic assembling device such as a dial that can be accurately made.

[0005]

The feature of the present invention is that the hitting member is capable of advancing and retracting and is capable of contacting a projection provided on a part to be assembled, and the hitting member is the above-mentioned member to be assembled. In the state of abutting against the component, one end surface of the hitting member is flush with the inner surface of the fitting portion of the component to be assembled,
This surface serves as a guide surface for guiding the protruding portion of the built-in component to the fitting portion.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, the overall configuration will be described. As shown in FIG.
A belt conveyor 1 of a transfer line is laid below, and a timepiece machine body 3 as an example of parts to be incorporated is placed and transferred on a pallet 2 provided at a predetermined interval on this conveyor. An assembling robot 4 is installed above the conveyor 1, and this robot has an X-axis moving body 4a.
And a Y-axis moving body 4b and a Z-axis moving body, that is, a vertical movement driving body 4c.
Is installed. A chuck body 7 is provided at the lower end of the drive shaft 6 a of the drive motor 6. As shown in Figure 1,
A plurality of chucks 7a are vertically provided on the lower surface of the chuck body 7, and a dial plate 8 as an example of a built-in component is sucked by the suction action of the chucks.
Then, the dial 8 is assembled to the timepiece mechanical body 3 in a state of being sucked by the chuck 7a.

By the way, as shown in FIG. 3, the outer shape of the dial plate 8 is a disk shape, and the projections 8a, 8a are integrally formed in a facing positional relationship. Further, the timepiece mechanical body 3 also has two protrusions 3 (only one of which is shown in FIGS. 1 and 2) facing each other on the outer peripheral portion.
There are a and 3a, and between these protrusions is a fitting groove 3b as an example of a fitting portion of the component to be assembled into which the projection 8a of the dial 8 can fit. The diameter of the timepiece mechanical body 3 is substantially equal to the outer diameter of the protrusion 8 a of the dial 8.

Next, the hitting device 10 will be described. As shown in FIGS. 1 and 2, the hitting device 10 includes a chuck body 7
Are provided at positions facing each other, and the hitting devices have substantially the same structure. An inverted L-shaped support 11 is fixedly installed, and a guide 11a having guide grooves formed in the left-right direction is vertically provided on the bottom surface of an upper plate extending to the left and right of the support. Further, a guide protrusion 9a is provided on the upper surface of the inverted L-shaped hitting member 9, and the guide protrusion is fitted into the guide groove of the support body 11,
A hitting member 9 is provided so as to be movable back and forth along the guide groove. Then, between the front surface of the base portion of the support 11 and the back surface of the hitting member 9, a compressed spring 12 which is a driving means for moving the hitting member 9 and the air cylinder 1 are provided.
3 and 3 are provided. A step portion 9b that is perpendicular to the lower surface is formed at the tip of the hitting member 9. The distance from this step portion to the tip surface 9c as an example of one end surface of the hitting member 9 is It is the same as the lateral width of the protrusion 3a of No. 3. The tip surface 9c of the hitting member 9 is formed so as to be able to abut on the projection 8a of the dial plate 8.

Next, the operation of the present invention will be described. First, when the air pressure of the air cylinder 13 is released, the spring 1
Due to the spring force of 2, the hitting member 9 advances, and the stepped portion 9b at the tip of the hitting member comes into contact with the projection 3a of the timepiece mechanical body 3 and stops. At this time, even if there is an error in the assembly position of the timepiece mechanical body 3, the hitting member 9 follows the error. This is the state shown in FIG. At this time, the hitting member 9
The front end surface 9c of the same is flush with the inner surface of the protrusion 3a of the timepiece mechanical body 3, that is, the inner surface of the fitting groove 3b. On the other hand, the dial 8 is positioned above the timepiece mechanical body 3 while being moved in the X and Y axis directions by the assembly robot 4.

Since the hitting members 9 and 9 are located in the tangential direction of the dial 8 as shown in FIG. 3, the vertical moving drive means 4c moves the dial 8 from the position shown in FIG. It can be lowered downward and is positioned at a level where it can contact the tip surface 9c of the hitting member 9. When the positional relationship between the protrusion 8a of the dial 8 and the hitting members 9, 9 at this time is seen from a plane, it is in the state of a chain line in FIG. Thereupon, the drive motor 6 is rotationally driven to rotate the dial 8 counterclockwise as shown in FIG. 3, and the projections 8a, 8a of this dial 8 are provided at the tips of the hitting members 9, 9 as shown by the solid line. The surfaces 9c, 9c are brought into contact with each other.

Then, when the dial 8 is lowered by the vertical movement drive means 4c, the projection 8a of this dial is flush with the tip surface 9c of the hitting member 9 and the projection 3a of the timepiece mechanical body 3. Guided by the inner surface of the watch body, the watch machine body smoothly enters and fits into the fitting groove 3b. That is, the tip surface 9c is a guide surface for guiding the projection 8a of the dial 8 to the fitting groove 3b of the timepiece mechanical body 3.

Thereafter, the suction action of the chuck 7a is stopped, the dial 8 is opened, and the chuck body 7 is raised.
At the same time, the air cylinder 13 is activated to activate the spring 12
The member 9 is retracted by contracting against the spring pressure of. This state is shown in FIG. Although the built-in component is the dial in this embodiment, it goes without saying that it is not limited to the dial.

[0013]

According to the present invention, since the hitting member can be moved back and forth, even if there is an error in the assembly position of the parts to be assembled, the hitting member can follow the error. Since one end surface of the above becomes the same surface as the inner surface of the fitting portion of the component to be embedded and acts as a guide when assembling the embedded component, the embedded component can be smoothly assembled.
