Abstract
The utility model relates to a liquid drop forming device with uniform drop forming of micro ball manufacture equipment, which is designed to improve the yield of finished products of equipment, reduce cost and save energy and materials. The liquid drop forming device comprises a crucible (1), the bottom part of which is provided with a through hole in advance, and the through hole is inlaid with a diamond hole die. The liquid drop forming device is characterized in that: a disturbance plate (29) is arranged in the center of the crucible, above the position where the diamond hole die is inlaid and below the liquid surface of molten metal; the disturbance plate is fixedly arranged on a vibratory conversion sheet (21) connected to a sound generator(20) through a rigid connecting rod (25); and the vibratory conversion sheet (21) is installed on a base (27) that is fixedly arranged on a cover (19) of the crucible.
Description
Affiliated technical field
The utility model relates to a kind of manufacturing equipment of fine ball.Said fine ball, its material especially (but being not limited to) are metal materials, and the about 0.01mm of its diameter is the tin ball as semiconductor-sealing-purpose to several mm, or the electric connection metal ball body of circuit board, electronic building brick.Follow-up application technology require this metal ball body be solid, to have high out of roundness and (requiring it with regard to same batch) size standardized.
Background technology
In the inert gas atmosphere of (this paper also regards nitrogen as inert gas), allow melt metal droplet cooled and solidified under state of weightlessness form fine ball, be the basic functional principle of fine ball manufacturing equipment.
The patent No. is that the Chinese patent literature of ZL20052000510.5 has been put down in writing relevant part technology.
This paper is by its function distinguishing, with the primary structure of this kind equipment be divided into the raw material melting appartus, liquid becomes drip apparatus, nodularization condensing unit, product gathering-device.
In the prior art, its liquid becomes drip apparatus to comprise a crucible, and the bottom of crucible is preset with through hole, and is embedded with diamond casement (overcoat is a metal, and the middle level is embedded with diamond, and central authorities are fine through hole) in the through hole.Motlten metal liquid level in crucible is arranged with a rotating mechanism, and it acts on a similar axial-flow pump, impels motlten metal through the oozing dropwise of the fine through hole on the diamond, forms drop.Its major defect is the big or small inhomogeneous of drop, makes that the yield rate of equipment is lower, has increased cost, forms the waste of the energy and material.
Summary of the invention
The one-tenth that the purpose of this utility model provides a kind of fine ball manufacturing equipment drips uniform liquid and becomes drip apparatus, to improve the yield rate of equipment, reduces cost, and saves the energy and material.
The corresponding techniques scheme is: flow through liquid in the fine through hole on the diamond with vertical disturbance of fixing (but adjustable) frequency and amplitude by sonic generator.Promptly the center of crucible, be embedded with the diamond casement the position above, under the liquid level of motlten metal, a disturbance plate is set; Disturbance plate is installed in the vibration conversion sheet that is connected to sonic generator through a rigidity connecting rod.
Its action principle is: when liquid because of the gravity effect from the mouth of pipe (being the fine through hole on the diamond) when flowing out with certain speed, if apply vertical disturbance of a fixed frequency to liquid in effuser inside, the internal pressure of liquid will be by distributed wave, when such liquid when the mouth of pipe penetrates, pressure changes the diameter that causes flow liquid corresponding the variation is taken place, surface tension of liquid at the diameter larger part is little, the surface tension of liquid of diameter smaller part is big. thereby the high liquid of pressure is to low the drawing close of pressure, reduce and make jet diameter be three-dimensional, form column type jet breakup pattern, thereby cause the generation of symmetrical liquid drop.
Its structure is: a kind of one-tenth of fine ball manufacturing equipment drips uniform liquid and becomes drip apparatus, comprises a crucible, and the bottom of crucible is preset with through hole, and is embedded with the diamond casement in the through hole; It is characterized in that: the center of crucible, be embedded with the diamond casement the position above, under the liquid level of motlten metal, a disturbance plate is arranged; Disturbance plate is installed in the vibration conversion sheet that is connected to sonic generator through a rigidity connecting rod.
The beneficial effects of the utility model: by the said structure feature with analyze as can be known, the utility model becomes to drip evenly, and the fine ball size that corresponding apparatus is produced is standardized, thereby can improve the yield rate of equipment, reduce cost, save the energy and material. realized goal of the invention.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic diagram of embodiment.
The specific embodiment
As shown in the figure, a kind of one-tenth of fine ball manufacturing equipment drips uniform liquid and becomes drip apparatus, comprises a crucible 1, and the bottom of crucible is preset with through hole, and is embedded with the diamond casement in the through hole; It is characterized in that: the center of crucible, be embedded with the diamond casement the position above, under the liquid level of motlten metal, a disturbance plate 29 is arranged; Disturbance plate is installed in the vibration conversion sheet 21 that is connected to sonic generator 20 through a rigidity connecting rod 25.
As shown in the figure, vibration conversion sheet 21 is installed on the pedestal 27, and pedestal 27 is installed in crucible pot cover 19.
As shown in the figure, pedestal 27 is provided with cooling chamber 28, and through cooling liquid inlet 281 and outlet, circulation has cooling fluid in the cooling chamber.
Sonic generator 20 the installation site, general in the switch board of equipment.
