Embodiment 1

[0022] Although the embodiments of the present invention are described below with reference to the drawings, the present invention is not limited to the embodiments of the present invention.

[0023] Example.

[0024] Such as image 3 As shown, the figure includes: a frame body, a release part supported by the frame body, a liquid material storage container and a control part that can control the release state of the liquid material. The components of the frame body 31 include: a frame body, which supports the guide rod 33 and screw shaft 32, the guide rod 33 guides the plunger support body 34 up and down, and the screw shaft 32 makes the plunger support body 34 driven by the motor 3 on the top of the frame body 31 move in the up and down direction; the lower frame body, which supports the discharge valve 4, the liquid material supply valve 10 and supports the metering section 1 through the discharge valve 4.

[0025] In the measuring part 1 supported by the frame body 31 an...

Embodiment 2

[0036] In the droplet forming device involved in Example 1, since air remains in the piping during filling, the pressure response may become dull due to the compressibility of the residual air. Therefore, the droplet forming device involved in this embodiment, It is attached on the plunger 2 of the droplet forming device related to embodiment 1 Figure 4 Air bubble extraction parts shown.

[0037] Plunger 2 comprises: plunger rod 21, and it has tubular portion, and aforementioned tubular portion has the hole 13 that communicates with outer wall surface; The air bubble removal hole 23 of the tubular part of 21 has a sealing part 24 on its outer wall that is closely attached to the inner wall surface of the metering part;

[0038] The upper part of the plunger rod 21 has a large-diameter cylindrical portion, and a flange portion is formed on the upper end portion, and the plunger rod 21 is fixed to the plunger support body 34 by this flange portion.

[0039] In the aforementio...

Abstract

It is a subject to provide a release amount adjustment method, a discharge method, and an apparatus thereof for discharging repeatedly discharged liquid droplets with high precision. A method for adjusting the amount of liquid droplets emitted from a discharge port communicating with the pipe by moving in and out and stopping in and out of a plunger that is slid close to the inner wall of the pipe, characterized in that the aforementioned The moving speed of the plunger moving in and out from the start decelerates to the stop, so that the liquid droplets discharged from the aforementioned discharge port can become a certain amount each time, and the discharge device includes: a tube; a column that slides close to the inner wall of the aforementioned tube A plug; a discharge port that communicates with the aforementioned tube to allow the liquid material to be sprayed and released; a control device for controlling the action of the aforementioned plunger, wherein the aforementioned control device controls the moving speed of the plunger that moves in and out from deceleration to stop.

Description

technical field [0001] The present invention relates to a method for repeatedly discharging liquid droplets (every discharge has a neat and uniform shape), or a method for adjusting the amount of liquid droplets discharged with high precision, a method for discharging liquid droplets, and a device thereof. Background technique [0002] In the conventional technique of sliding the plunger against the inner surface of the tubular component to splash the liquid droplets, there is a method of advancing the plunger with its front end closely connected to the liquid material at a high speed, and then abruptly stopping the driving of the plunger. A technique in which a liquid material exerts an inertial force to release the liquid material (for example, refer to Patent Document 1). In addition, there is also a technique in which the plunger is arranged in a liquid feeding passage that communicates between the liquid material discharge nozzle and the storage portion that stores the ...
