Abstract

A rotational wave nozzle. A self-rotating type rotational wave nozzle that prevents the number of rotations from being higher than necessary. In the rotational wave nozzle, a rotary cylinder is supported by two bearings provided separately in an axial direction inside a fixed housing such that the rotary cylinder is freely rotatable. A spray nozzle is connected to the rotary cylinder, and the rotary cylinder is self-rotated through inclinedly ejecting compressed air supplied to a hollow section of the rotary cylinder relative to a surface of a disc. An annular member is provided to the rotarycylinder, movable attraction members being movable in a radial direction and being urged inward in the radial direction by a biasing member are installed at an outer periphery of the annular member, and fixed attraction members are installed on an inner wall of a protective cover and arranged in a circumferential direction so as to face the mobile attraction member. As the number of rotations of the rotary cylinder increases, the mobile attraction members approaching the fixed attraction members increase the mutual attractive force, and the number of rotations of the rotary cylinder decreasesand therefore does not exceed the prescribed number of rotations.

Description

technical field [0001] The invention relates to a rotary wave nozzle which intermittently blows fluid to workpieces. Background technique [0002] An air gun is known as a device for blowing fluid to a workpiece. The air gun sprays compressed air and blows the injected compressed air to the wet-cleaned workpiece to blow off liquid droplets, thereby drying the workpiece. This type of air gun is also used in the shipping process of semiconductor chips. That is, in the shipping process of semiconductor chips, for example, use a warm water bath to clean the trays that transport and protect the semiconductor chips to be shipped, blow compressed air to the wet trays with an air gun to blow off droplets, and place the trays in a dry place. oven to dry it. [0003] In the blow drying method using an air gun, there is a phenomenon that the droplets crawl on the surface of the tray or go around to the back. Therefore, in the drying with the air gun, the liquid droplets remaining on...
