Description

[Detailed description of the invention] (a) Technical field of the invention The present invention relates to a spherical handling nozzle.

(b) Background of the Technology The present invention is a proposal relating to an automatic handling nozzle that sucks and holds metal spheres, each having a diameter of, for example, about 0.2 to 0.5 mm, and supplies them to an assembly device.

(c) Prior Art and Problems A conventional handling nozzle, which is the object of the present invention, will be explained with reference to FIG.

In the figure, 1 is an axially long handling shaft whose upper part is connected to a vacuum pump, the lower end of which is formed with a spherical suction hole 4 for vacuum suction, 2 is a tray for storing a large number of spheres, and 3 is the above-mentioned It is a sphere.

The handling shaft 1 inserts its tip into the sphere storage tray 2, sucks up any single sphere, and supplies it to the sphere assembly apparatus.

However, the sphere 3 after washing and drying
When picking up, for example, if the spheres are charged with static electricity, a plurality of spheres will have to be picked up at the same time, which is extremely inconvenient. Furthermore, even if the cleaning liquid remains on the tray 2, a similar situation occurs, and the monocytes cannot be supplied to the assembly apparatus, resulting in various inconveniences.

(d) Purpose of the invention The present invention aims to solve the above problems.

According to the present invention, the conventional handling nozzle is improved to have a nozzle configuration that reliably picks up spheres one by one during operation.

(e) Structure of the invention The object of the invention is to suction and hold an assembled sphere at the end of the suction hole of a cylindrical handling shaft provided with a suction hole opening at the lower end along the internal longitudinal direction. In the handling nozzle to be moved to the assembly device side, the handling nozzle is configured as a separate part from the handling shaft, and is slidable from the lower end upward on the outer surface of the handling shaft, and This is achieved by having a donut-shaped auxiliary nozzle with a gas ejection hole opening in the direction.

(f) Embodiments of the invention Hereinafter, embodiments of the invention will be described with reference to FIGS. 2 and 3.

FIG. 2 is a sectional view of this embodiment, and FIG. 3 is a perspective view of FIG. 2.

In these figures, reference numeral 5 denotes a spherical suction hole that passes through the axis of the handling shaft 1 and has an opening angle of, for example, 45° to facilitate vacuum suction at the end 4 of the hole, and 8 represents the handling shaft according to the present invention. It is a donut-shaped auxiliary nozzle that can slide up and down on the outer surface of the nozzle.

When the spheres 7 are sucked, extra spheres 3 adhere due to static electricity or cleaning liquid left in the previous process, but these extra spheres 3 can be removed by moving the auxiliary nozzle up and down (arrow 10).
It can be handled mechanically by letting it go. This extra sphere 3 is attached only to the periphery of the sphere 7 in Fig. 3, but as this number increases, the handling axis 1
It will also adhere to the outer surface of the.

If, for example, a cleaning gas for the sphere is used as the gas in the gas jet hole 6, the subsequent assembly of the sphere will be more effective. Note that reference numeral 9 is a connecting gas pipe to a gas source that supplies gas to the gas jet hole 6.

With such a handling nozzle, sphere operations such as sphere pick-up and subsequent sphere transfer, which rely on conventional human hands and eyes, can be carried out extremely easily.

(g) Effects of the Invention According to the above-described handling nozzle of the present invention, the suction of the sphere and the operation of moving the nozzle to the object to be supplied can be carried out extremely easily, and the practical value is great.

[Brief explanation of drawings]

Fig. 1 is a perspective view of a conventional spherical handling nozzle, Fig. 2 is a sectional view showing an embodiment of the present invention, and Fig. 3 is a perspective view of a conventional spherical handling nozzle.
The figure is a perspective view of FIG. 2. In the figure, 1 is a handling shaft, 2 is a sphere storage tray, 3 is a sphere, 5 is a sphere suction hole with a nozzle suction end 4 at the lower end of the shaft 1, 7 is a sucked sphere, and 8 is an air jet hole 6. It is an auxiliary nozzle.

Claims (1)

[Claims] 1. A cylindrical handling shaft having a suction hole extending along the internal longitudinal direction and opening at the lower end, and holding the assembled sphere under suction at the end of the suction hole to assemble the sphere. In the handling nozzle that is moved to the device side, it is configured as a separate part from the handling shaft,
It is characterized by having a donut-shaped auxiliary nozzle that is slidable from the lower end upwards on the outer surface of the handling shaft and that has a gas ejection hole that opens in the direction of the outer surface of the handling shaft. Spherical handling nozzle.
