Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an apparatus for aligning and supplying electronic components.

[Background technology]

Conventionally, when carrying out aligned conveyance of small electronic components 1 having terminals 2 extending toward the mounting surface on both sides of a rectangular parallelepiped component body as shown in FIGS. 1 and 2A and B, FIG. A carrier magazine 3 shown in FIG. 4 or a tape 5 wound around a reel 4 shown in FIG. 4 are used. The electronic component 1 is a mini mold package type transistor or diode. However, these methods require a dedicated package such as the carrier magazine 3 and tape 5, which requires a large amount of materials, and the cost of parts increases as the package requires. Therefore, it has been proposed to align and supply electronic components with a vibrating hopper, but the vibrating hopper causes the electronic components 1 to be in an inverted position with the terminals 2 facing upward, which is inconvenient to handle in subsequent processes.

Furthermore, as a means for feeding cylindrical cup-shaped parts, a pipe chute in which a pipe with a rectangular cross section is twisted at 180 degrees has been proposed. According to this, the above-mentioned cylindrical cup-shaped component can be reversed and transported smoothly.

However, since the pipe chute has a rectangular cross-sectional shape, it is difficult to smoothly transport an electronic component 1 having a vertically asymmetrical shape and having terminals 2 as shown in FIG. That is, in the case of an electronic component 1 having terminals 2 on both sides of the component body extending toward the mounting surface of the component body, smooth transportation is difficult because the cross-sectional shape of the pipe chute does not match the electronic component.

Furthermore, since the pipe chute has a rectangular cross-sectional shape and is vertically and horizontally symmetrical, it is possible to transport the electronic part 1 having the above-mentioned shape even if the electronic part 1 is supplied to the entrance section in either direction, up or down. Therefore, if the electronic component 1 is supplied to the pipe chute in the wrong vertical direction, it will be transported as is, which will cause trouble in the subsequent process.

[Purpose of the invention]

The object of the present invention is to provide a simple structure and manufacturing method that enables electronic components to be reversed and aligned and supplied without using a packaging body, etc., and that also has a function to prevent incorrect feeding of electronic components whose supply orientation is reversed. An object of the present invention is to provide an alignment and feeding device.

[Disclosure of the invention]

The alignment and supply device of the present invention is an alignment and supply device for aligning and supplying electronic components having terminals on both sides of the component body extending toward the mounting surface of the component body.
A lid is provided on the open surface of the half-split pipe to create a spiral shape.
A pipe chute having a 180° screw thread, and a component feeder that supplies the electronic components one by one to the entrance of the pipe chute with the component mounting surface facing the lid and the terminals located on both sides of the pipe chute. It is equipped with the following.

According to the configuration of the present invention, since it is equipped with a pipe chute that is spirally twisted at 180 degrees and a component supply device, it is possible to invert and supply electronic components in an aligned manner without using a package or the like. .

In addition, since the pipe chute is made up of a half-split pipe and a lid provided on the open surface of the pipe, when sending an electronic component that has terminals on both sides of the component body that extend toward the mounting surface of the component body, the pipe chute The cross-sectional shape of the electronic component matches well with the cross-sectional shape of the electronic component, allowing smooth feeding.

Moreover, since the cross-sectional shape of the pipe chute and the vertically asymmetrical electronic component fit well, even if an electronic component is supplied to the entrance of the pipe chute in the wrong orientation, the upside-down electronic component will not enter the pipe chute. Can not. Therefore, the pipe chute also has the function of preventing erroneous feeding of electronic components, and it is possible to prevent problems in subsequent processes and products with defective electronic component mounting.

Furthermore, this invention not only matches the cross-sectional shape of the pipe chute to the shape of the electronic component;
Since it consists of a half-split pipe and a lid, there is no need to process it into a special shape, and the pipe chute is easy to manufacture.

Embodiment An embodiment of the present invention is shown in FIGS. 5 to 8. In the figure, reference numeral 7 denotes a base, on which a vibrating hopper 8 serving as a parts feeder is installed via a leaf spring 9. Reference numeral 10 denotes an oscillation block section that is provided on the base 1 and vibrates the vibration hopper 8. Vibration hopper 8
A rectilinear alignment section 8a is provided therein for arranging the stored parts in a line, and a sorting gate 11 is provided at the exit of the rectilinear alignment section 8a. Sorting gate 1
1 is connected to a pipe chute 12. The pipe chute 12 is attached to a pipe chute mount 13, one end of which is supported by the base 7 by a leaf spring 14, and the other end is attached to the vibrating hopper 8. The pipe chute 12 has a half-pipe-shaped chute body 12a.
A cover body 12b is attached to the top and the lid body 12b is screwed in a 180° spiral. The pipe chute 12 is installed so that the vibration hopper 8 side has a flat top surface. The chute body 12a is made by cutting a pipe made of stainless steel or the like into a spiral shape using a milling machine or the like, and the lid body 12b is also made of a thin plate of stainless steel and is welded to the chute body 12a.

With this configuration, the electronic components 1 accumulated in the vibration hopper 8 are moved straight to the alignment section 8a by vibration.
Most of the electronic components 1 are arranged in a line with the terminals 2 facing upward as shown in FIG. 8A. Electronic components 1 whose terminals 2 do not face upward cannot pass through the sorting gate 11 and are dropped into the storage section within the vibrating hopper 8 again. The electronic component 1 with the terminal 2 facing upward enters the pipe chute 12 as shown in Fig. 7A, and while passing through the pipe chute 12, it is inverted as shown in Figs. 7B and C and is erected with the terminal 2 facing downward. Supplied with attitude. In this way, the electronic components 1 can be sequentially aligned and supplied in an upright position. Therefore, unlike the conventional carrier magazine 3 and tape 5
There is no need for this, and material savings can be achieved.

In addition, since the pipe chute 12 consists of a half-pipe-shaped chute main body 12a and a lid body 12b, the shape of the pipe chute 12 matches the shape of the electronic component 1 with terminals 2 protruding from both sides as shown in FIG. Allows for smooth feeding. Moreover, since the cross-sectional shape of the pipe chute 12 and the vertically asymmetrical electronic component 1 fit well, the pipe chute 12
Even if the electronic component 1 is supplied to the entrance of the pipe chute 12 upside down, the upside down electronic component 1 (electronic component in an upright position) cannot enter into the pipe chute 12. Therefore, the pipe chute 12 is connected to the electronic component 1.
It also has the function of preventing erroneous feeding, and has the effect of preventing problems in subsequent processes and products with defective electronic component 1 mounting.
Furthermore, the pipe chute 12 is simply an electronic component 1
Not only is the cross-sectional shape adapted to the shape of the chute body 12a, but also the chute body 12a in the form of a half-split pipe and the lid body 12b do not need to be processed into a special shape, and the structure is simple and easy to manufacture. It is.

In this case, since the height dimension H within the pipe chute 12 can be manufactured stably, clogging of the electronic component 1 within the pipe chute 12 can be prevented. The rest is the same as the first embodiment.

FIGS. 11 and 12 show still other embodiments. In this example, a groove 15 is provided along the center of the lid 12d. In this case, if the electronic component 1 becomes clogged in the pipe chute 12, it can be easily handled. Furthermore, the state of inversion of the electronic component 1 can be observed.

FIGS. 13 and 14 show still other embodiments. In this example, a protrusion 12e' that abuts the electronic component 1 is provided along the center of the inner surface of the lid 12e. In this case, in the electronic component 1, the molded body portion is the protrusion 1
Since it is guided in contact with the terminal 2e', it has better dimensional stability and rigidity than in the case where it is guided in contact with the terminal 2, and therefore clogging in the pipe chute 12 is prevented.

FIGS. 15 and 16 show still other embodiments. In this example, the lid body 12f is connected to the chute body 12a.
The width is such that an opening 16 can be formed on one side of the lid body 12.
A protrusion 12f' is provided on the lower surface of f to be in contact with the molded part of the electronic component 1. In this case, since the molded part of the electronic component 1 is guided in contact with the protrusion 12f', clogging in the pipe chute 12 is prevented. Further, since the opening 16 is provided, it is easy to handle the case where the electronic component 1 is clogged in the pipe chute 12, and the inverted state of the electronic component 1 can be observed.

[Effects of the Invention] Since the aligning and supplying device of the present invention includes a pipe chute that is spirally twisted at 180° and a component supplying device, it is possible to invert and align electronic components without using a package or the like. can be supplied.

In addition, since the pipe chute consists of a half-split pipe and a lid provided on the open surface of the pipe, the pipe chute is suitable for sending electronic components that have terminals on both sides of the component body that extend toward the mounting surface of the component body. The cross-sectional shape of the electronic component matches well with the cross-sectional shape of the electronic component, allowing smooth feeding.

Moreover, since the cross-sectional shape of the pipe chute and the vertically asymmetrical electronic component fit well, even if an electronic component is supplied to the entrance of the pipe chute in the wrong orientation, the upside-down electronic component will not enter the pipe chute. Can not. Therefore, the pipe chute also has the function of preventing erroneous feeding of electronic components, and it is possible to prevent problems in subsequent processes and products with defective electronic component mounting.

Furthermore, this invention not only matches the cross-sectional shape of the pipe chute to the shape of the electronic component;
