DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component which can be picked up by an automatic mounting machine.

[0002]

2. Description of the Related Art Conventionally, as a method of mounting an electronic component on a substrate, an automatic mounting machine is generally used today. The automatic mounting is a series of continuous operations by a machine in which a supplied component is picked up and mounted on a substrate. This picking-up operation is performed by the suction nozzle. FIGS. 5A and 5B show that the suction nozzle 2 of the automatic mounting machine is approached from right above the hexahedron electronic component 1 having flat surfaces.
The state where the electronic component 1 is being sucked by the suction force is shown. In this suction state, the suction nozzle 2 is in contact with a flat surface having a suction cross-sectional area equal to or larger than the suction cross-sectional area to prevent the inflow of air, and sucks the electronic component 1 by using a suction force. Then, the sucked component is carried to a specific portion of the substrate to be mounted, separated from the suction nozzle 2 by removing the suction force, and mounted.

[0003]

In the suction operation, the suction portion 3 of the electronic component 1 in contact with the suction nozzle 2
It is necessary that there is no step which causes the inflow of air which hinders the suction, that the surface is flat, and that the suction nozzle has an area larger than the suction cross-sectional area of the suction nozzle. However, in the prior art, FIG.
As shown in (b), in the case of the electronic component 4 having a block-shaped outer shape including a portion where the first surface 5 and the second plane 6 are continuous at the step 7, the surface contacting the suction nozzle 2 has a step. 7, the surface was not flat, and the air inflow portion 8 was formed. Therefore, the suction force was reduced and suction was not performed, and the automatic mounting machine was not applied.

Therefore, an object of the present invention is to fill and flatten a portion that inhibits suction and eliminate an air inflow portion 8 so that the electronic component 4 can be mounted on an automatic mounting machine. An object of the present invention is to provide a structure capable of performing automatic suction while securing suction force and automatically mounting.

[0007]

According to a first aspect of the present invention, in the first aspect, the adapter that is flush with the second plane is fixed to the first surface, so that the suction nozzle of the automatic mounting machine can be placed flat on the electronic component without any step. In addition, since the contact is made beyond the suction cross-sectional area of the suction nozzle, the suction of the air can be secured by preventing the inflow of air, and the electronic component can be sucked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings using a dielectric filter as an example of an electronic component. Depending on the required characteristics, the dielectric filter may have a step for adjusting the coupling and the like. However, in any of these examples, the suction nozzle 2 is applied to the step and the air flows in as it is. The suction power does not work.

(Embodiment 1) Embodiment 1 is shown in FIG. There is a dielectric filter 9 having an outer shape in which a second plane 6 in contact with the suction nozzle 2 is continuous with the first surface 5 via a step 7. A rectangular parallelepiped adapter 10 is attached and fixed to the first surface 5 of the dielectric filter 9. This adapter 10 is flat on all six sides, has the same height as the step 7 of the dielectric filter 9, and has a surface that is in contact with the first surface 5 and its opposing surface is slightly narrower than the first surface 5; 2 provides an area larger than the air inflow portion that prevents adsorption.
Thereby, the second plane 6 is complemented by the adapter 10,
The suction nozzle 2 has a flat area equal to or larger than the cross-sectional area of the suction nozzle 2, so that the suction force of the suction nozzle 2 can be secured and suction is performed.

(Embodiment 2) Embodiment 2 is shown in FIG. 2, and the same parts as those in the first embodiment are denoted by the same reference numerals and the description is omitted. The adapter 11 used in the present example is a tetrahedron having three flat surfaces and the other surface being a semicircle drawing an arc. It has the same height as the step 7 of the dielectric filter 9, and the surface in contact with the first surface 5 and the opposing surface thereof are slightly narrower than the first surface 5, and are at least equal to the inflow portion of the air that prevents the suction nozzle 2 from adsorbing. Provide area. Thereby, the second plane 6 is complemented by the adapter 11 and has a flat area equal to or larger than the cross-sectional area of the suction nozzle 2, so that the suction force of the suction nozzle 2 can be secured and suction is performed.

(Embodiment 3) Embodiment 3 is shown in FIG. First
The same parts as those of the embodiment are denoted by the same reference numerals, and the description is omitted.
In this example, the first surface 5 and the second surface 6 shown in FIG. 1 of the first embodiment and FIG. An octahedral adapter 12 having a flat surface and covering the step 7 continuously is fixed to the first surface. As a result, the second plane 6 is completely covered by the adapter 12 and has a flat area equal to or larger than the cross-sectional area of the suction nozzle 2, so that the suction force of the suction nozzle 2 can be secured and the suction is performed. Become.

Each of the adapters of the first to third embodiments has a flat surface exceeding the cross-sectional area of the suction nozzle 2 by filling the step between the first surface and the second plane of the dielectric filter 9 with respect to the suction nozzle 2. Is complementarily provided as an adsorption area. Thus, the suction nozzle 2 can stably secure a suction force without being affected by the step 7 of the dielectric filter 9 and can perform suction.

(Embodiment 4) Embodiment 4 is shown in FIG. In this example, after the adapter 10 is attached to the dielectric filter 9, the surface thereof is covered with the film 13, so that the planarization of the contact portion between the dielectric filter 9 and the suction nozzle 2 is further stabilized, and the suction with the nozzle 2 is performed. The degree is further strengthened. Also,
In some cases, cover with a label instead of film.

Regarding the shape and the material of the adapter, the material is not limited to resin and metal as long as the adapter can provide a flat surface capable of stably securing the suction force of the suction nozzle. In fixing, a surface in contact with the dielectric filter is fixed with an adhesive. In some cases, instead of the adhesive, it is fixed by soldering.

[0016]

According to the first aspect of the present invention, there is provided an electronic component body having a block-like outer shape including a portion in which a first surface and a second plane are continuous with a step, and has a flat surface. Since the suction adapter having a shape in which the plane is flush with the second plane of the electronic component body is fixed to the first surface of the electronic component body, the suction nozzle of the automatic mounting machine is attached to the electronic component. On the other hand, since the contact is made on a flat surface without any step and exceeding the suction cross-sectional area of the suction nozzle, it is possible to prevent the inflow of air, secure the suction force, and have the effect of sucking the electronic component.

[0017]

As described above, since an electronic component having a step on the surface facing the suction nozzle due to required characteristics can be sucked by the suction nozzle by using the adapter, automatic mounting is possible, and the number of steps is reduced. This leads to higher accuracy and lower costs.
