Cam type fluid discharge device

Abstract

The present invention provides a cam type fluid dispenser which correctly realizes piston rotation and reciprocation through a single cam mechanism that comprises a single driving part and two cam parts, thereby dispensing fixed amount of fluid without leakage. The cam type fluid dispenser according to one embodiment of the invention comprises the following components: a cam mechanism which comprises a rotating shaft that is rotatably equipped on a housing, a first cam part and a second cam part which can rotate together with the rotating shaft; a vertical reciprocation driving part which is configured at one side of the cam mechanism and can rotate vertically through interlocking with the first cam part; a piston part which can move vertically according to rotation of the vertical reciprocation driving part and can rotate according to the second cam part of the cam mechanism; and a nozzle unit which is equipped at the lower part of the piston part, finishes inflow and discharging of the fluid through vertical movement of the piston part, and closes an inflow opening and a discharging opening of the fluid according to rotation movement of the piston part.

Description

technical field [0001] The present invention relates to a discharge device, and in particular to a single cam mechanism including a single drive part and two cam parts to accurately realize the rotation and reciprocation of a piston (Plunger), thereby discharging a certain amount of fluid without leakage and enabling simple adjustment Discharge cam type fluid discharge device. Background technique [0002] Recently, in the electronic component industry, devices for discharging fluids such as functional illuminants such as LEDs, ultrafine-particle cream solders, and adhesives in a set amount have been developed and used. [0003] figure 1 A general structure of a piston type fluid discharge device as one of such fluid discharge devices is shown. [0004] The piston type fluid discharge device includes: a casing 1; a cylinder 2 arranged inside the casing 1; a piston 4 that reciprocates and rotates inside the cylinder 2; and a nozzle mechanism 5 installed at the lower end of ...

AI Technical Summary

Problems solved by technology

In this state, the fluid inside the cylinder flow path may leak through the suction port and discharge port

In particular, when the fluid is discharged at high pressure in order to increase the discharge volume, such fluid leakage cannot be ignored

[0012] In order to solve the above-mentioned problem, people use the structure that utilizes two driving parts to rotate and reciprocate the piston. increased manufacturing costs
