[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component rotating jig.

[0002]

2. Description of the Related Art For electronic components with a plurality of external electrodes, such as a capacitor network and an LC filter,
External electrodes are applied and baked around the periphery,
In order to form external electrodes of such electronic components, FIG.
As shown in FIG. 1A, first, in order to form the external electrodes 2 on two opposing surfaces of the electronic component 1, it is necessary to apply a conductor paste and then rotate the paste 90 degrees. After rotating as in b), the remaining two surfaces are similarly coated. The markings 3 are provided to confirm the positional relationship before and after the rotation of the electronic component, and each of the white arrows in the figure indicates the external electrode application direction.

Conventionally, a manual method or a method using an actuator such as a motor has been adopted as such a rotation method.

[0004]

[Problems to be solved by the invention] However, in the case of the manual method, the direction of each electronic component is changed by hand,
Insertion into the external electrode coating jig requires time and effort, and requires a large number of people during mass production, resulting in an increase in the unit cost of parts.When actuators such as motors are used, the equipment costs are large, and at the same time There were problems such as difficulty in processing many pieces.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electronic component rotating jig which can rotate an electronic component in a simple and inexpensive manner and requires no manual operation.

[0006]

The inventors of the present invention have conducted research to achieve the above object, and as a result, have a U-shaped cross section which satisfies the following structural conditions shown in the side sectional view of FIG. The groove 5 is provided on the plate-like body 4, and the groove is covered with a lid so that the groove becomes a through-hole, an electronic component is inserted from the upper electronic component input port 6, and is removed from the lower output port 7. The present inventors have found that the problem can be solved by using at least one unit of the jig, and arrived at the present invention. Note that, for the purpose of explaining the internal shape of the through-hole in an easy-to-understand manner, the above-mentioned “lid” is formed by dividing a flat jig by a virtual plane parallel to the main surface of the flat plate to determine the thickness of the flat plate. This means one flat plate portion when equally divided, and it is not necessary that the jig is actually divided into a lid and a non-lid portion. Therefore, the lid can be considered as a simple flat plate or a flat plate including a part of the groove. (1) The electronic component inlet 6 and the outlet 7 are slightly wider than the width of the electronic component. (2) The protrusion 8 is provided in the middle of the groove 5, and the protrusion of the protrusion protruding from the wall surface of the groove is smaller than the distance from the center of gravity of the electronic component to the end face of the electronic component. (3) In the protrusion, the center line of the groove is moved in parallel by the overhang distance. (4) The arc 10 on the wall opposite to the tip 9 of the projection is drawn with a radius R substantially equal to or slightly larger than the length of the diagonal line of the main surface of the electronic component. (5) A jig having a structure in which a cover is attached so as to cover the groove and the groove is a through hole.

Therefore, the present invention is an electronic component rotating jig for dropping an electronic component from the upper portion, removing the electronic component from the lower portion, and rotating the electronic component in the falling direction by 90 degrees during the drop. Has a structure in which a lid is attached so as to cover the groove of a plate-like body having a U-shaped groove in cross section so that the groove becomes a through hole, and the width of the groove is larger than the width of the electronic component. Slightly wide, in the middle of the groove, on one wall constituting the groove, there is a protrusion projecting from the wall surface, and in the protrusion, the center line of the groove moves parallel to the protrusion distance of the protrusion. The overhang distance is smaller than the distance from the center of gravity of the electronic component to the end face,
The wall surface on the opposite side of the protrusion is formed as an arc surface with a radius equal to or slightly larger than the length of the diagonal line of the main surface of the electronic component to be input, with the base point where one wall transitions to the protrusion. An electronic component rotating jig is provided.

[0008]

The jig of the present invention shown in FIG. 1 is set so that the electronic component feeding direction is perpendicular to the plane, and the electronic component is loaded and rotated. The behavior of the electronic component in the groove at this time is as shown in FIG. 3, and FIGS. 3A to 3D respectively show when the electronic component is inserted, when the electronic component starts rotating, when the electronic component is rotating, and when the electronic component is rotating. This shows the end of the component rotation.
The electronic component 1 inserted from the electronic component insertion port 6 falls in the groove 5, and a part of the electronic component collides with the tip 9 of the projection 8, and the electronic component rotates around this point. . When the electronic component is rotated by 90 degrees, the electronic component passes through the tip 9 of the protrusion, and enters the electronic component outlet 7 from the initial state.
Appears rotated 90 degrees.

It is a perspective view which shows the jig | tool at the time of inverting a component, It demonstrates below with reference to these.

Each of the electronic components held in a large number of holes provided in the rubber carrier plate 11 has an end portion of the component protruding from the plate, and an external electrode is applied and formed on the protruding portion. It is dried as it is.

Next, the carrier plate 11 holding the electronic components is placed on the jig unit assembly 12 of the present invention, and the held components are extruded by a press equipped with pins.

The extruded electronic component is a jig shown in FIG.
A guide plate that is rotated by 90 degrees in 12 and falls, and is provided under the jig knit assembly 12 and at a position corresponding to the carrier plate 11, a hole having a wider component entrance side is provided.
Guided to 13.

Next, after removing the carrier plate 11 and the jig unit assembly 12 from which the electronic components have been extruded, the electronic components are rotated by 90 degrees when they are extruded by a press machine with pins and set on the next carrier plate. Will be loaded.

[0014]

[Effect of the Invention] As described above, the jig of the present invention can be taken out in a state rotated by 90 degrees simply by inserting the electronic component from the input port, so that the efficiency is higher than the conventional method.
