Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a conveyance device that conveys a workpiece and positions the workpiece relative to a processing device during automatic assembly.

Prior Art and Problems When performing automatic assembly, generally, as shown in FIG. It is positioned with respect to the assembly device 4, and then screwed etc. are performed by the assembly device 4. In addition, in the same figure, 5 is a conveyor frame that supports the conveyor 3.

Further, as a positioning device for positioning the carrier 2 with respect to the assembly device 4, for example, a device whose top view and side view are shown in FIGS. 2A and 2B, respectively, is used. In Figures A and B, 6 is a base fixed to the carrier frame 5, 7 is a pin, 8 is a cylinder fixed to the base 6 for raising the pin 7, and 9 and 10 are provided on the back side of the carrier 2. 11 and 12 are positioning pins, and 13 is a cylinder for raising the positioning pins 11 and 12.

When positioning the workpiece 1 mounted on the carrier 2 with respect to the assembly device 4 using the positioning device shown in FIGS. 2A and 2B, the pin 7 is first raised by the cylinder 8 and the carrier 2 is stopped. Next, the cylinder 13 raises the positioning pins 11 and 12 by a predetermined amount. As a result, positioning pin 1
1 and 12 and the recesses 9 and 10 provided on the back surface of the carrier 2 are engaged with each other, and the carrier 2 is raised by a predetermined amount. Thereafter, assembly work such as screw tightening is performed by the assembly device 4.

In the conveying device using the positioning device shown in FIGS. 2A and 2B, the positioning of the work 1 and the assembly of the work 1 are performed as described above. Since the positioning device 1 is provided below the work 1, the lower part of the work 1 cannot be automatically assembled. Therefore, when assembling the lower part of work 1,
It is necessary to correct the orientation of the workpiece 1 or to assemble it manually, which has the drawback of poor workability.

OBJECT OF THE INVENTION The present invention has improved the above-mentioned drawbacks, and its purpose is to provide a conveyance device that can automatically assemble the lower part of the workpiece. Examples will be described in detail below.

Embodiment of the invention FIGS. 3A to 3C are a plan view, a side view, and a sectional view taken along line a-a' of an embodiment of the invention, respectively, and FIG. 4 is a perspective view showing the configuration of the carrier 20. .
In FIGS. 3A to 3C and FIG. 4, 14 is a stopper fixed to the transport device frame 5, 20 is a carrier, 21 is an opening provided in the carrier 20,
22 is a workpiece placement section on which the workpiece 1 is placed, 2
3 and 24 are concave portions provided on the back surface of the carrier 20, 25 is a conveyance section of the carrier 20, and 26 is an assembly device, and the same reference numerals as in other FIGS. 2A and 2B represent the same parts.

The workpiece mounted on the workpiece mounting section 22 of the carrier 20 by the conveyance device of this embodiment is transferred to the assembly device 26.
When positioning against and performing assembly work,
First, the pin 7 is raised by the cylinder 8, and the carrier 20 conveyed by the conveyor 3 is stopped. Next, the positioning pins 11 and 12 are raised by the cylinder 13. As a result, the recesses 23 and 24 provided on the back surface of the carrier 20 fit into the positioning pins 11 and 12, and the carrier 20 rises until the upper surface of the conveying section 25 comes into contact with the stopper 14.

The workpiece 1 is positioned with respect to the assembly apparatus as described above. In this embodiment, the carrier 20 is provided with an opening 21, and a workpiece mounting section is provided at a position opposite to the opening 21. 22 is provided, and the workpiece 1 is placed on the workpiece placing portion 22. Therefore, the lower part of the workpiece 1 can be assembled by the assembly device 26 through the opening portion 21 provided in the carrier 20. I can do it.

Effects of the invention As explained above, in the present invention, since an opening is provided in the carrier on which the work is mounted, the lower part of the work can be automatically assembled, and therefore work efficiency can be increased. There are advantages that can be achieved. Furthermore, there is a space between the opening and the workpiece placement section through which you can insert your hand, making it easy to manually process the back side of the workpiece.
