FIG. 6 shows a squeezing type conveying belt.
Is a hoop-shaped metal belt, 13 is a feed hole, 16 is a hole drawn on the metal belt 11 for storing electronic components, and 15 is a stored electronic component.

FIG. 7 shows a vacuum suction type conveyor belt.

[0006]

However, each of the above-mentioned conventional belts for transporting electronic components has the following disadvantages.

That is, in the punching-type transport belt shown in FIG. 5, a part of the electronic component 15 protrudes from the bottom surface of the metal belt 10 and comes into contact with the lower surface of the rail located below the metal belt 10. If the part 15 is dirty or damaged,
There is a problem that it jumps out during transportation.

Further, in the drawing type conveying belt shown in FIG. 6, since the drawing material is used as the hoop-shaped metal belt 11, if it is repeatedly used, elongation occurs and the positioning accuracy is not high. was there.

Further, the vacuum suction type transfer belt shown in FIG. 7 can transfer only the electronic component 18 having a shape which can be suctioned by vacuum. However, there is a problem that the occurrence of the problem occurs.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide an electronic component transport belt capable of transporting electronic components of various shapes stably.

[0011]

According to the present invention, there is provided an electronic component conveying belt according to the present invention, wherein a holding member connecting hole is provided at a constant pitch in a central portion of a hoop-shaped metal belt. A central part, a recess for accommodating an electronic component, a flange on the upper surface, which is tightly engaged with the upper surface of the metal belt, and an engagement protrusion, which is closely engaged with the lower surface of the metal belt on the side surface. And a holding body formed by providing a slit for attaching to and detaching from the metal belt at the center line of the upper surface.

[0012]

According to this structure, the electronic component is inserted into the concave portion of the holding body and transported, so that the electronic component does not come into contact with the lower surface of the rail during transport, and the electronic component is not damaged or stained. . Further, by setting the depth of the concave portion optimally, it is possible to prevent the electronic component from jumping out.

Further, since a resin molded product is used as a holder for the electronic component, it is possible to cope with the transfer of electronic components of various shapes, and since the holder for the electronic component is provided with a projection. Can be easily attached to and detached from the metal belt.

Further, since a metal material having a high tensile strength can be used as the material of the transport belt, the accuracy can be guaranteed even if the belt is repeatedly used.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an electronic component conveying belt according to an embodiment of the present invention.

FIG. 1 is a perspective view of a main part showing the structure of an electronic component conveying belt according to the present invention, which comprises a metal belt 1 and a holder 4.

FIG. 2 is a perspective view showing the metal belt 1 shown in FIG. 1 above. The metal belt 1 has a holder coupling hole 2 for coupling a holder 4 and a metal belt 1 for conveying the metal belt 1. Feed holes 3 are provided at a constant pitch.

FIG. 3 shows a resin holder which is connected to the holder connecting hole 2 of the metal belt 1 shown in FIG. 1. The holder 4 accommodates electronic components in the center. For storing electronic components, a flange 6 closely engaged with the upper surface of the metal belt 1, and a lower surface of the metal belt 1 when the holder 4 is coupled to the holder coupling hole 2 of the metal belt 1. An engaging projection 7 is provided in close contact with the holding member 4, and a detachable slit 8 is provided at the center of the holder 4.

The concave part 5 for storing electronic parts is provided with a taper at the entrance so that the electronic parts can be easily inserted, and the engaging projection 7 is provided with a taper so as to be easily inserted into the metal belt 1. Further, a slit 8 is provided so that the holding body 4 can be easily detached from the metal belt 1, so that the engaging projection 7 is easily detached.

FIG. 4 is a cross-sectional view along the line AA 'in FIG. 1 showing a state in which the electronic component 9 is stored in the electronic component transport belt according to the embodiment.

The insertion and removal of the electronic component 9 are as follows.
This is performed by using a vacuum suction head or a chuck from above the holding body 4.
A configuration in which the lift-up pin is used to assist the lifting may be adopted.

Further, since the holder 4 is formed by resin molding, it can be formed according to the shape of various electronic components.

[0023]

As described above, since the electronic component transport belt of the present invention inserts and transports electronic components into the recesses of the resin holder, the electronic components may come into contact with the lower surface of the rail. No, not hurt or dirty.

Further, by setting the depth of the concave portion to an optimum size, not only the protrusion of the electronic component can be prevented, but also because the resin molded product is used as the electronic component holder, various shapes can be obtained. A holder suitable for electronic components can be created.

The holding member has a flange on the upper surface connected to the upper surface of the metal belt and an engaging projection on the side surface connected to the lower surface of the metal belt, so that the holding member can be easily inserted into and removed from the metal belt. Therefore, even if the holder is broken, it can be easily replaced, which is advantageous for maintenance.

Further, since a metal belt having a high tensile strength is used, many effects can be obtained such that the accuracy can be guaranteed even if the belt is used repeatedly, and that it can be used for a long time.
