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, an automatic mounting machine has been generally used as a method for mounting electronic components on a substrate. Automatic mounting is a series of continuous mechanical operations of picking up the supplied components and mounting them on a board. This picking-up operation is performed by the suction nozzle, but in FIGS. 5A and 5B, the suction nozzle 2 of the automatic mounting machine is brought close to from directly above the hexahedral electronic component 1 having flat surfaces.
The state in which the electronic component 1 is 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 or more to prevent the inflow of air and exert suction force to suck the electronic component 1. Then, the sucked component is carried to a specific portion of the board to be mounted, the suction force is cut off, and the component is separated from the suction nozzle 2 and mounted.

[0003]

In this suction operation, the suction portion 3 of the electronic component 1 with which the suction nozzle 2 is in contact,
It is necessary to have a flat surface without a step that causes the inflow of air that hinders adsorption, and to have an area equal to or larger than the suction cross-sectional area of the suction nozzle. However, in the conventional technique, as shown in 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 flat surface 6 are continuous with the step 7, the step is formed on the surface in contact with the suction nozzle 2. 7 was not flat and an air inflow part 8 was formed, so the suction force was reduced and adsorption was not possible, and the automatic mounting machine could not be contacted.

Therefore, the object of the present invention is to fill the portion that obstructs the suction to make it flat so that the electronic component 4 can be hung on the automatic mounting machine, and to eliminate the air inflow portion 8 so that the suction nozzle 2 can be installed. An object is to provide a structure that can be automatically mounted by securing suction force and sucking.

According to a first aspect of the present invention, there is provided an electronic component main body having a block-shaped outer shape including a portion in which a first surface and a second flat surface are continuous with a step, and the flat surface is provided. And a suction adapter having a shape in which this plane is flush with the second plane of the electronic component body is fixed to the first face of the electronic component body.

According to a second aspect of the present invention, there is provided an electronic component main body having a block-shaped outer shape including a portion in which the first surface and the second plane are continuous by a step, and the flat surface has the plane, and the plane is the electronic surface. An adsorption adapter having a shape also positioned on the second plane of the component body is fixed to the first surface of the electronic component body.

[0007]

According to the present invention, in claim 1, by fixing the adapter, which is flush with the second plane, to the first plane, the suction nozzle of the automatic mounting machine is flat on the plane without any step with respect to the electronic component. In addition, since the suction nozzles come into contact with each other exceeding the suction cross-sectional area, the inflow of air can be prevented, the suction force can be secured, and the electronic component can be sucked.

According to the second aspect of the present invention, the suction nozzle of the automatic mounting machine is much more stable with respect to electronic parts by fixing the adapter whose plane is also located on the second plane to the first plane. Then, since they contact each other on a flat surface without a 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 suck the electronic component.

Embodiments of the present invention will be described below with reference to the drawings using a dielectric filter which is an example of an electronic component. Depending on the required characteristics, the dielectric filter may have a step due to adjustment of coupling or the like. However, since all of these examples have a step, the suction nozzle 2 hangs on the step and air flows in as it is. Therefore, the attraction force 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 flat surface 6 in contact with the suction nozzle 2 is continuous with the first surface 5 via a step 7. The 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 the surface in contact with the first surface 5 and its facing surface are slightly narrower than the first surface 5, and the suction nozzle It provides an area larger than the inflow part of the air which prevents the adsorption of 2.
As a result, the second plane 6 is complemented by the adapter 10,
Since a flat area equal to or larger than the cross-sectional area of the suction nozzle 2 is held, the suction force of the suction nozzle 2 can be secured and the suction is performed.

(Embodiment 2) Embodiment 2 is shown in FIG. 2. The same parts as those in the first embodiment are designated by the same reference numerals and their description is omitted. The adapter 11 used in this example is a tetrahedron whose three surfaces are flat and the remaining one surface is a semicircle that draws an arc. The surface having the same height as the step 7 of the dielectric filter 9 and having a surface contacting the first surface 5 and a surface facing the first surface 5 are slightly narrower than the first surface 5 and are equal to or larger than the inflow portion of the air which prevents the suction of the suction nozzle 2. Provide area. As a result, 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 in the embodiment are designated by the same reference numerals and the description thereof will be omitted.
In this example, in order to completely planarize the dielectric filter 9 that contacts the suction nozzle 2, the first plane 5 and the second plane 6 shown in FIG. 1 of the first embodiment and FIG. 2 of the second embodiment are used. And an octahedron adapter 12 having a flat surface for continuously covering the step 7 is fixed to the first surface. As a result, the second flat surface 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 suction is performed. Become.

Each of the adapters of Examples 1 to 3 fills the step between the first surface and the second plane of the dielectric filter 9 with respect to the suction nozzle 2 and is a flat surface exceeding the cross-sectional area of the suction nozzle 2. Is provided as a complementary area. As a result, the suction nozzle 2 can stably secure a suction force without being affected by the step 7 of the dielectric filter 9, and suction can be performed.

(Embodiment 4) Embodiment 4 is shown in FIG. In this example, after the adapter 10 is attached to the dielectric filter 9, the surface of the adapter 10 is covered with the film 13 to further stabilize the flattening of the contact portion between the dielectric filter 9 and the suction nozzle 2 and to suction the nozzle 2 Further strengthening the degree. Also,
In some cases, cover with label instead of film.

Regarding the shape and material of the adapter, the shape of the adapter 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. At the time of fixing, it is fixed with an adhesive on the surface in contact with the dielectric filter. Also, in some cases, soldering is used instead of the adhesive.

[0016]

According to the present invention, in claim 1, there is provided an electronic component body having a block-shaped outer shape including a portion in which the first surface and the second plane are continuous at a step, and the electronic component body has a plane surface. Since the suction adapter having a flat surface flush with the second flat surface of the electronic component main body is fixed to the first surface of the electronic component main 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 plane without a 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 suck the electronic component.

According to a second aspect of the present invention, there is provided an electronic component body having a block-shaped outer shape including a portion where the first surface and the second plane are continuous with a step, and the electronic component body has a plane and the plane is the electronic device. Since the suction adapter having a shape that is also positioned on the second plane of the component body is fixed to the first surface of the electronic component body, the suction nozzle of the automatic mounting machine is more effective than the electronic component. Since the contact is made in a stable manner on a flat surface without exceeding a step and exceeding the suction cross-sectional area of the suction nozzle, the inflow of air is prevented, a suction force is secured, and an electronic component can be sucked.

As described above, since electronic parts having a step on the surface facing the suction nozzle due to the required characteristics can be picked up by the suction nozzle by using the adapter, automatic mounting becomes possible and the number of steps is reduced. It will lead to improvement of accuracy and cost reduction.
