Embodiment Construction

[0056] Before continuing the description of the present invention, the same reference numerals are given to the same parts in the drawings.

[0057] The embodiments of the present invention will be described in detail below based on the drawings.

[0058] The following is about the first embodiment of a dispenser for surface mounting suitable for electronic components, using figure 1 The fluid application device of the fluid application method of the present invention will be described.

[0059] 1 is the first transmission device. In the first embodiment, in order to supply high-viscosity fluid with a small amount and high precision at high speed and intermittently, it is used to obtain high positioning accuracy and high responsiveness, and at the same time A giant magnetostrictive element with a large generated load can be obtained.

[0060] 2 is the central axis driven by the first transmission device 1. The first transmission device is installed in the sleeve 3. The front main...

Abstract

A method of applying fluid includes feeding fluid to between two faces disposed with a gap maintained therebetween and changing the gap between the two faces by driving of an actuator for intermittently discharging the fluid filled in between the two faces, wherein an input signal in which a high-frequency component and a DC component are superimposed is given to drive the actuator for changing the gap between two faces, so that the fluid filled in between the two faces is intermittently discharged for fluid application.

Description

Background technique [0001] The present invention relates to a production process that can be used in the fields of electronic components, household appliances, etc., and is used to quantify various liquids such as adhesives, paste solder, phosphors, grease, paint, hot melt substances, medicines, and foods. Discharged fluid supply device and supply method. [0002] Liquid discharge devices (distributors) have been used in various fields for many years. However, in recent years, with the miniaturization of electronic components and the demand for higher recording density, technologies for high-precision and stable control of discharge of trace fluid materials have also been proposed. Requested. [0003] Taking the field of surface mount (SMT) as an example, in the development trend of high-speed, miniaturization, high-density, high-quality, and unmanned installation, if you summarize the issues of distributors, it is roughly [0004] (1) High precision of coating amount and miniatu...
