Description

[Detailed description of the invention] [Industrial application field] This invention consists of a first terminal provided at the center of the circular bottom surface of a cylindrical body, and a second terminal provided apart from the first terminal. The present invention relates to an automatic feeding device for electronic components that always orients the first terminal of the electronic component in a direction opposite to the transport direction.

[Conventional technology]

For example, when supplying diodes, opto-devices, transistors, etc. to marking devices, characteristic measuring devices, etc., it is necessary to adjust the orientation of each element.

A vibrating parts feeder is generally used to supply such elements, but it is difficult to align the orientation of electronic components with the above shape inside the vibrating parts feeder, so a device for aligning the orientation is required in addition to the vibrating parts feeder.

If the rotation for adjusting the orientation is performed mechanically, the structure becomes complicated and expensive, and maintenance becomes difficult.

[Problem that the invention attempts to solve]

This invention aims to convey the orientation of the first terminal of an electronic component having a first terminal provided at the center of the circular bottom of a cylindrical body and a second terminal provided apart from the first terminal. It is an object of the present invention to provide an automatic feeding device for electronic components that is always arranged in the opposite direction.

[Means for solving problems]

The automatic feeding device of this invention has first and second structures, and the first and second structures are provided with a space for inserting the first and second terminals, and have a downward slope with respect to the conveying direction. the first
The structure supports the bottom surface of the electronic component on the front surface and supports the first terminal on the side surface, and the second structure includes:
providing a portion that supports the side surface of the electronic component on the side surface and a convex portion that supports the bottom surface of the electronic component on the surface;
The gap is of a size that allows the electronic component to rotate around the first terminal when facing the conveyance direction, and the convex portion allows the gap to be larger than the outer diameter of the first or second terminal. It is characterized by that it consists of a part that narrows to a dimension slightly larger than the outer diameter of.

[Example of idea]

FIG. 1 shows an example of the shape of an opto-device, which is one of the electronic components to which this invention is applied.

In the figure, 11 is a main body whose envelope is made of ceramic in a cylindrical shape, 12a is a terminal arranged on the bottom surface of the main body 11 so as to overlap the center line of the main body 11, and 12b is a terminal arranged on the bottom surface of the main body 11 with a terminal 12a. These terminals are arranged in parallel.

An embodiment of this invention is shown in Figs. 2a, b, and c.

Figure a is a perspective view, Figure b is a plan view, and Figure C is a front view. In the figures, 1 is the opto-device shown in Figure 1, and 11, 12a, 12b indicate the same parts with the same reference numerals as in Figure 1. , 2 is a first structure that supports the bottom surface of the main body 11 of the device 1 with its surface 21, supports the terminal 12a of the device 1 with its side surface 22, and allows the device 1 to slide down by its own weight; and 3 is the first structure 2 with its side surface 31. 32 is a guide piece that guides the terminals 12a and 12b of the device 1.

The first structure 2 and the second structure 3 are inclined in such a manner that the distal end sides in FIG.
If it is placed in contact with the surface, it will slide down due to its own weight.
At this time, the side surface of the device 1 is pressed against the side surface 31 of the second structure 3, and the terminal 12a is pressed against the side surface 31 of the second structure 3.
It is supported in contact with the side surface 22 of the terminal 12a, and slides down while rotating around the terminal 12a.

When the device 1 is placed on the first structure 2,
The terminal 12b located at an arbitrary angle with respect to the sliding direction is rotated by the rotation of the device 1.
When the device 1 reaches a state where it comes into contact with the side surface 22 of the structure 2, the rotation of the device 1 is stopped and the device 1 is sent out while maintaining its orientation.

Note that if the terminals 12a, 12b are constructed to pass through a gap slightly larger than the larger diameter terminal 12a, 12b formed by the guide piece 32, the reliability of the effect will be increased.

[Effect of idea]

As described above, according to this invention, an electronic component shaped like a so-called E-type opto-device is automatically fed to the next process equipment after being oriented using a simple and inexpensive device. It has become possible to do so and has great practical effects.
