Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is intended for use in electronic devices that have a non-conductive part and a conductive part, such as a variable resistor mounted on a printed wiring board of an electronic device. The present invention relates to a magazine device for electronic components that accommodates components in a serial manner so as to be freely guided.

(Prior Art) Conventionally, in electronic devices, automatic insertion machines have been used to mount electronic components such as variable resistors onto printed wiring boards that make up internal devices, in order to improve production. ing. As shown in FIG. 1, such an automatic insertion machine includes a magazine machine 1 in which, for example, a variable resistor 12 is housed in series so as to be freely guided on a table 11 for insertion work.
3 is attached in a substantially vertical manner, and the insertion work is performed using its natural fall.

FIG. 2 shows such a conventional magazine 13, in which a substantially cylindrical first magazine corresponding to the variable resistor 12 is provided.
A second accommodating portion 132 is provided which is arranged parallel to the first accommodating portion 131 in a substantially L-shape. The magazine 13 has a resistor board 14 of the variable resistor 12 and first and third terminals 15 and 16 extending to the ends of the resistor board 14 relative to the first accommodating part 131. A second terminal 17 is provided in a substantially L-shape in correspondence with the first and third terminals 15 and 16 from one side of the resistor substrate 14 in the second accommodating portion 132. Each is accommodated with appropriate play. Therefore, when the magazine 13 in which a plurality of variable resistors 12 are housed in series is vertically installed in an automatic insertion machine, the variable resistors 12 are inserted into the first and second housing sections 131 and 132. The material is allowed to fall naturally along the line, and then fed into an automatic insertion machine and transferred.

(Problem to be solved by the invention) However, in the magazine device for electronic components mentioned above,
Due to its structure, when the variable resistor 12 is in the housed state, unless there is enough play between the variable resistor 12 and the magazine 13 to allow the variable resistor 12 to fall naturally, smooth guiding operation will be difficult. etc., due to the play, the variable resistors 12 overlap each other in the magazine 13 as shown in FIG. There is a problem that makes it difficult. According to this, the variable resistor 12 is no longer supplied from the magazine 13 while the automatic insertion machine is in operation, making subsequent insertion operations difficult.
A problem arises in that malfunctions such as loading mistakes in the automatic insertion machine occur, reducing its operating rate.

This idea was made in view of the above circumstances, and the electronic components are guided to be transferred while regulating the position of the electronic components in the magazine to ensure that the electronic components are transferred by natural falling. The problem to be solved is to provide a magazine device.

[Structure of the invention] (Means for solving the problem) This invention provides an electronic component in which a plurality of electronic components each having a non-conductive part and a conductive part are housed in a magazine so as to be freely guided. In the magazine device, a pair of guided protrusions that are protruded in directions opposite to each other across the non-conductive part are provided on the conductive part of the electronic component in a direction substantially perpendicular to the guiding direction, and A measure is taken to provide a pair of protrusions in the column direction that sandwich and guide the protrusions in the conductor portion of the electronic component.

(Function) According to the above means, the pair of protrusions of the electronic component are sandwiched between the protrusions of the magazine, and the electronic component is transported and guided within the magazine while its position is regulated.
The non-conductive portion and the conductive portion do not come into contact with the inner wall of the magazine, and the magazine is transferred by gravity.
Therefore, even if an external force such as vibration is applied from the outside during transportation due to natural falling of electronic components, the position of each electronic component is regulated by the protrusion, and the electronic component remains in its normal position in the magazine. is maintained, and subsequent transport by gravity can be carried out without any problem.

(Example) Hereinafter, an example of this invention will be described in detail with reference to the drawings.

FIGS. 4a, 4b, and 4c show a side view, a front view, and a plan view of a magazine device in which variable resistors 20 are housed in series so as to be movable in the directions of arrows A and B, respectively. That is, a substantially rectangular resistor substrate 21 constituting the variable resistor 20 has first and third terminals 22 and 23 at predetermined positions on one side thereof.
is attached with solder 24. These first and third terminals 22 and 23 are formed to extend from the end of the resistor board 21 so as to be mounted on a printed wiring board (not shown), and the first and second terminals 22 and 23 for positioning guide are formed in the intermediate part thereof. Projections 25 and 26 are formed in the surface direction of the resistor substrate 21.

Further, on the resistor board 21, a slider 27 for adjusting the resistance value is attached to a stopper 28 at a predetermined position on the other side.
The rotation can be freely adjusted via the . A conductive anti-rotation member 29 is attached to the slider 27 so as to protrude from one side of the resistor substrate 21 . Further, the rotation prevention member 29 has a substantially L-shaped second terminal 30 at one end thereof, which can be mounted on the printed wiring board (not shown) in correspondence with the first and third terminals 22 and 23. At the same time, a third protrusion 31 for positioning guide is formed at the other end to protrude in a substantially opposite direction to the first and second protrusions 25 and 26.

On the other hand, a substantially cylindrical magazine 32 in which the variable resistors 20 are accommodated in a manner that they can be guided in series is formed to have a substantially L-shaped cross section in correspondence with the variable resistors 20 .
This magazine 32 has a resistor board 21 of the variable resistor 20 at one end of the L-shape, and a first
and the third terminals 22, 23 are accommodated, and the second terminal 30 is accommodated at the other end of the L-shape, and the first and third terminals 22, 23 are accommodated.
An inwardly convex regulating portion 33 is formed in the cylindrical direction (column direction) at a corresponding position between the first terminal 30 and the second terminal 30 . The magazine 32 also has a first protrusion 34 for guiding corresponding to the first and second 25, 26 of the variable resistor 20 on its inner wall, and a first protrusion 34 for guiding the variable resistor 20.
Second guiding protrusions 35 corresponding to the third protruding parts 31 are formed in the cylindrical direction. These first and second protrusions 34 and 35 are formed opposite to each other, and the first and third protrusions of the variable resistor 20
The third protrusion 31 and the protrusions 25, 26 of the third protrusion 31 are configured to be guided so as to be sandwiched therebetween.

That is, in the magazine device configured as described above, the variable resistor 20 housed in series with the magazine 32 is connected to the first and second resistors formed in the conductor portion with the resistor substrate 21 sandwiched therebetween. Projection 2
5, 26 and the third protrusion 31 are sandwiched between the first and second protrusions 34, 35 of the magazine 32, while the first to third terminals 22, 30, 23 are inserted into the restriction part 33. The location will be regulated and guided. As a result, as shown in FIGS. 4a, b, and c, the variable resistor 20 has its non-conducting portion, the resistor substrate 21, and the tips of the first to third terminals 22, 30, and 23 in the magazine. Since there is no contact with the inner wall of the variable resistor 20, the movement of the variable resistor 20 in the cylindrical direction is always guided.

In this way, in the magazine device, the first to third protrusions 25, 26, 31 of the variable resistor 20 are sandwiched between the first and second protrusions 34, 35 of the magazine 20, and their positions are regulated. By configuring the variable resistor 20 to fall naturally, the resistor substrate 21 of the variable resistor 20 and the first to third terminals 22, 30,
The conductor section 23 is guided in movement without coming into contact with the inner wall of the magazine. According to this, even when vibration etc. are applied from the outside, each variable resistor 2
0 is the first to third protrusions 25, 26, 31
The position of the magazine 32 is regulated by the first and second protrusions 34 and 35 of the magazine 32 to ensure that the magazine 32 is housed in a movable state in a normal position. Therefore, in this magazine device, as shown in FIG. 1, the variable resistor 20 in the magazine 32 is always fed by gravity falling to the table 11 of the automatic insertion machine, which prevents loading mistakes in the automatic insertion machine. This facilitates the prevention of such malfunctions and contributes to improving the operating rate of the automatic insertion machine.

Furthermore, since the above magazine device minimizes the displacement when the variable resistor 20 moves within the magazine 32, even if a protrusion such as a burr occurs on the resistor substrate 21, it can be ignored. Therefore, it is possible to improve manufacturability.

Note that this invention is not limited to the above embodiments,
It goes without saying that various other modifications can be made without departing from the gist of the invention.

[Effects of the invention] As detailed above, according to this invention, the electronic parts are guided to be transferred while regulating their position in the magazine, so that the electronic parts are surely transferred by natural falling. It is possible to provide a magazine device for electronic components.
