Abstract

(57) [Abstract] [PROBLEMS] To provide a component transfer device equipped with a suction nozzle capable of transferring a hollow component having a hollow hole. A suction nozzle 1 provided with a conical protrusion 2 to be inserted into a hollow hole 5a of a hollow component 5 and a suction hole 3 having an opening 3a closed on the surface of the hollow component 5 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component transfer device including a suction nozzle that sucks and transfers a hollow component having a hollow hole.

[0002]

[Prior Art]

 When a component such as an IC chip is transferred and placed on a substrate, for example, the IC chip has pins around it, so if you try to transfer it by pinching it with a tweezer-like device, you will not be able to pinch it well. It may damage the pins. Therefore, when a component such as an IC chip is transferred, the suction nozzle connected to a vacuum pump is brought into contact with the surface of the component, and the vacuum pump lowers the air pressure inside the suction nozzle, so that the suction nozzle Parts are adsorbed and transferred.

[0003]

[Problems to be solved by the device]

 In the above conventional technology, if a component to be transferred has a hollow hole, when the suction nozzle comes into contact with this hollow hole, the suction nozzle cannot suck the component having this hollow hole and transfer it. is there. An object of the present invention is to provide a component transfer device equipped with a suction nozzle capable of sucking a hollow component such as an IC chip having a hollow hole.

[0004]

[Means for Solving the Problems]

 The component transfer device of the present invention for achieving the above object is a cone-shaped protrusion that is inserted into a hollow hole of a hollow component from the apex side, and a cone-shaped protrusion that is formed close to the cone-shaped protrusion. The suction nozzle is provided with a suction hole having an opening that is closed by the surface of the hollow component when the is inserted into the hollow hole.

[0005]

[Action]

 In the component transfer device of the present invention, the conical protrusion is inserted into the hollow hole of the hollow component to align the suction nozzle with the hollow hole. In this way, the suction holes come into contact with the surfaces of the aligned hollow parts, so that negative pressure is applied to the surface of the parts that block the opening of the suction nozzle to suck the hollow parts with hollow holes. Then, it can be transferred to a predetermined position.

[0006]

【Example】

 Embodiments of the present invention will be described below. FIG. 1 is a cross-sectional side view showing a state in which a suction nozzle of a component transfer device of the present invention suctions a hollow component. The conical protrusion 2 of the suction nozzle 1 of the component transfer device (not shown) is inserted into the hollow hole 5a of the hollow component 5. As a result, the suction nozzle 1 and the hollow component 5 are aligned with each other. At this time, the opening 3a of the suction hole 3 is closed by the surface of the hollow component 5. After this, the air pressure in the suction hole 3 is lowered by a vacuum pump (not shown), the hollow component 5 is adsorbed by the suction nozzle 1 and transferred to a predetermined position.

A suction nozzle 1 having a structure shown in FIG. 1 was manufactured, and the suction nozzle 1 was mounted on a vacuum pump of 5 L / min and 250 Torr specifications, and 100 hollow parts weighing 0.5 gf were transferred. The success rate was 100%.

[0008]

[Effect of the device]

 Since the component transfer device of the present invention is provided with the suction nozzle provided with the conical protrusion inserted into the hollow hole of the hollow component and the suction hole having the opening closed on the surface of the hollow component, Hollow parts having holes can be adsorbed and transferred. Since the present invention differs from the conventional component transfer device only in the shape of the suction nozzle, it can be used simply by replacing the conventional suction nozzle. Also, even if the tip of the conical protrusion deviates from the center of the hollow hole, the inclined surface of the conical protrusion slides along the edge of the hollow hole and is inserted toward the center of the hollow hole. As a result, the alignment is accurately performed, and the hollow component can be reliably sucked and transferred. This technique can also be applied to handling of cylindrical parts (machine elements, etc.) (robot arms, etc.).
