Abstract

PURPOSE:To align electronic components from which lead wires are projected and, at the same time, to easily, accurately and manually count the number of the components by providing parallel grooves having widths wider than the diameters of the lead wires on the surface of an aligning plate and forming recessed sections having sizes larger than those of the component bodies in the middles of the grooves. CONSTITUTION:After placing an appropriate number of electronic components (a) on an aligning plate 1, with their lead wires (b) being roughly directed in the direction of grooves 2 on the surface of the plate 1, the plate 1 is vibrated. As a result, the bodies (c) of the components (a) and lead wires (b) respectively get in recessed sections 3 and grooves 2. Then the components (a) of which the bodies (c) is not inserted in the sections 3 are removed from the plate 1 by tilting the plate so that the side of the plate 1 where no surrounding frame 4 is provided on the bottom side. In case some of the recessed sections 3 are empty, part of the removed components (a) are put in the sections 3. Therefore, the number of components (a) aligned on the plate 1 can be easily recognized when all the recessed sections 3 are occupied by the components (a).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for arranging a plurality of electronic components in order to count the number of electronic components whose lead wires are led out from a component body.

[0002]

2. Description of the Related Art A disk feedthrough capacitor or a stepped feedthrough capacitor is a disk-shaped or stepped disk-shaped porcelain body in which a lead wire is passed through the center axis and soldered. Conventionally, when counting the number of these electronic components, electronic components are lined up and sent out by a parts feeder, etc., and a counting device in which an optical sensor or a mechanical sensor is arranged in the middle of the transportation route is used to sequentially transport the components on the transportation route. The electronic components sent were counted while being detected one by one by the sensor. Such a counting device is incorporated in an electronic component packaging device, and is sequenced so that one unit of packaging is completed when a predetermined number of electronic components are counted.

[0003]

However, in the case of electronic parts produced in small quantities, since the number of electronic parts to be handled is relatively small, the electronic parts whose lead wires are led out from the parts main body are aligned by the parts feeder. Difficult and inefficient. Further, the lead wires are often entangled with each other, and the two wires are overlapped with each other and sent by the parts feeder. In that case, since they are counted as one electronic component, a counting error is likely to occur, and the reliability of the counting result is high. It was low. Therefore, it has been impossible to package an accurate number of electronic components.

In view of the conventional counting means for electronic parts, the present invention easily and accurately counts the number of electronic parts whose lead wires are led out from the parts main body, not by a parts feeder, and manually. It is an object of the present invention to provide a jig that enables easy and accurate counting of small lots of electronic components.

[0005]

That is, in order to achieve the above-mentioned object, the present invention counts the number of electronic parts a from which the lead wire b is led out from at least one end side of the part body c. A jig for arranging electronic parts a, in which a plurality of grooves 2 having a width wider than the diameter of the lead wire b of the electronic parts a are provided in parallel on the surface of the alignment plate 1, and the parts 2 are provided in the middle of these grooves 2. Provided is an electronic component counting jig, which is characterized in that a concave portion 3 larger than the main body c is formed.

[0006]

In the electronic component aligning jig according to the present invention, a plurality of grooves 2 having a width larger than the diameter of the lead wire b of the electronic component a are provided in parallel on the surface of the aligning plate 1, and these grooves 2 are provided in the middle of the grooves 2. Since the concave portion 3 larger than the component main body c is formed, the lead wire b is aligned on the alignment plate 1 approximately in the direction of the groove 2, and an appropriate number of electronic components a are mounted to vibrate or swing. Etc. are added to the alignment plate 1, the component body c of the electronic component a is placed in the concave portion 3,
The lead wires b of the same part a are fitted into the grooves 2 which are continuous with the recess 3. When the component body c of the electronic component a is fitted in almost all the recesses 3, the electronic component a in which the component body c is not fitted in the recess 3 is removed from the alignment plate 1, and the component body c of the electronic component a is fitted therein. When there is a concave portion 3 which is not present, the electronic component a is fitted into the concave portion 3 and the groove 2 which is continuous with the concave portion 3. As a result, the electronic components a are fitted into all the concave portions 3 and the grooves 2 that are continuous with the concave portions 3, so that the electronic components a are left on the alignment plate 1 by the number of the concave portions 3, and the number can be easily confirmed.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 to 4 show examples of counting stepped feedthrough capacitors as electronic components a. As shown in FIG. 1, the aligning plate 1 has a rectangular shape, but it is preferably a transparent plate made of acrylic resin, polystyrene resin, or the like. An enclosing frame 4 is erected from the three sides of the aligning plate 1 on the upper surface side thereof.

A plurality of grooves 2 having a width slightly wider than the diameter of the lead wire b of the electronic component a to be counted are provided in parallel on the upper surface of the alignment plate 1. In the illustrated embodiment, the groove 2 is provided in a direction parallel to the surrounding frame 4 standing upright from the two opposite sides of the aligning plate 1, but 90 ° with the illustrated direction.
Of course, the grooves 2 may be provided in different directions. As shown in FIGS. 3 and 4, the depth of this groove 2 is
The diameter is approximately the same as the diameter of the component body c of the electronic component a.

As shown in FIG. 1, recesses 3 are provided in the middle of the groove 2 in a line in the arrangement direction of the groove 2. As shown in FIGS. 3 and 4, the width of the recess 3 is slightly larger than the diameter of the component body c of the electronic component a, and the length thereof (dimension in the longitudinal direction of the groove 2) is the length of the component body c. (The length of the lead wire b in the longitudinal direction), and its depth is substantially the same as the diameter of the component body c.

As shown in FIG. 1, in the illustrated embodiment, the grooves 2 are provided in three rows, and the recesses 3 in each row are provided with the grooves 2.
It is provided every other. Further, the recesses 3 in the two rows on both sides are provided in the same groove 2, and the recesses 3 in the center row are provided in the groove 2 different from them. Accordingly, when the recesses 3 having a width wider than that of the groove 2 are provided, the interval between the grooves 2 can be narrowed while avoiding the interference of the adjacent recesses 3. Further, since the three rows of the recesses 3 are arranged so as to be displaced, it is possible to easily confirm whether or not the component bodies c of the electronic components a are fitted in all the recesses 3.

As described above, when the number of electronic components a is counted by using this counting jig, the lead wires b are aligned on the alignment plate 1 in the direction of the groove 2, and an appropriate number is obtained. The electronic component a is mounted and the alignment plate 1 is vibrated or swung. Then, the component body c of the electronic component a is fitted in the recess 3, and the lead wire b of the electronic component a is fitted in the groove 2 continuous with the recess 3. At a place where the electronic component a is fitted into almost all the recesses 3 and the grooves 2 connected to the recesses 3, the alignment plate 1 is surrounded by the surrounding frame 4.
Inclining so that the side on which no
The electronic component a in which the component body c is not fitted in is removed from the alignment plate 1. Then, when there are some recesses 3 in which the component body c of the electronic component a is not fitted, the alignment plate 1
A part of the electronic component a removed from the above is fitted into the concave portion 2 and the groove 2 continuous with the concave portion 2. As a result, the electronic component a is fitted into all the recesses 3 and the grooves 2 that are continuous with the recesses 3. In this state, as many electronic parts a as the number of the concave portions 3 remain on the alignment plate 1, and the number can be easily confirmed.

Next, the embodiment shown in FIGS. 5 and 6 will be described. In the counting jig according to this embodiment, the recesses 2 are arranged in the arrangement direction of the grooves 2 without separately providing the recesses 3. Are connected in a groove shape. In this case, since the width of the groove 2 is sufficiently narrower than the length of the component body c of the electronic component a, the component body c of the electronic component a fits in the groove 2 and leads b
Does not fit into the recess 3. That is, as shown in FIG. 2, the electronic component a can be surely fitted into the recess 3 and the groove 2 and aligned. This embodiment is suitable when it is necessary to align a large number of electronic components a on the alignment plate 1 having a limited width.

Next, the embodiment shown in FIGS. 7 and 8 will be described. The counting jig according to this embodiment is an example in which the number of disk feedthrough capacitors as electronic parts a is counted. Since the length of the component body c (the length of the lead wire b in the longitudinal direction) of the through-disk capacitor is shorter than that of the stepped through-capacitor, when the recessed portions 3 are long as shown in FIGS. 5 and 6, The component body c is fitted into the groove 2 and the recess 3
The lead wire b may be fitted in, and it becomes difficult to align the lead wires. Therefore, the concave portions 3 are appropriately divided and connected so that the total length of the continuous concave portions 3 is sufficiently shorter than the length of the lead wire b. In the case shown in the figure, the recesses 3 are divided into two rows of the grooves 2 and are continuous. Also, in this embodiment, the alignment plate 1
The direction of the groove 2 formed in is different from the above-mentioned embodiment by 90 °.

Although all of the above-described embodiments are examples of the feedthrough capacitor counting jig, the lead wires are led out from the component body such as an axial lead type electronic component or a radial lead type electronic component. It is obvious that the present invention can be similarly applied to a jig for counting the number of electronic components.

[0015]

As described above, according to the present invention, it is possible to easily and accurately count the number of electronic components, whose lead wires are led out from the component body, without using a parts feeder, and to manually count them. It is possible to provide various jigs, and in particular, it is possible to obtain an effect that counting of electronic components in a small lot can be performed easily and accurately.
