Embodiment 1

[0047] exist Figure 1~Figure 4 Among them, a microsphere semi-automatic dispensing and sealing device of the present invention includes a three-view mirror high-pressure air chamber, a precise positioning three-dimensional mobile sample stage, a dispensing system, and a long working distance imaging system;

[0048] The high-pressure inflatable chamber of the three-view mirror adopts a cylindrical structure, and the center axis of the circle is placed in the horizontal direction. The front and rear of the high-pressure inflatable chamber of the three-view mirror are equipped with circular sealing covers, and the left side is axially provided with a horizontal Direction window, the right side is rotated 45 degrees counterclockwise along the horizontal axis to set a 45-degree direction window; the observation port of the left window facing the high-pressure inflatable chamber of the three-view mirror is equipped with a horizontal long working distance microscope, which is connec...

Embodiment 2

[0076] In this embodiment, the PMAS gold-coated microspheres are used to fill with argon

[0077] The implementation process of this embodiment is the same as the method of embodiment 1, the difference is that in this embodiment, the dispensing wire 2 in steps b, c, d, f, g uses tungsten wire; steps a, d, g The diameter of micropore 4 in is 20 μ m;

[0078] In this example, due to the poor light transmittance of the metal microspheres, the micropores cannot be observed by using the bottom light. In the implementation process (d) in the pre-adjustment of the micropores of the inflated microsphere samples, only the side top light source can be used. Adjust the irradiation angle and control the brightness, and need to increase the hole diameter to 20μm to observe the microholes more clearly and complete the glue sealing.

Abstract

The invention discloses a semi-automatic dispensing hole-sealing device and method for a microballoon, and the device is used for achieving the semi-automatic dispensing hole-sealing method for the microballoon. The method mainly comprises the steps: (a), performing the laser perforation of a to-be-inflated microballoon sample; (b), performing the bonding of dispensing wires; (c), performing the pre-judgment of the tips of the dispensing wires; (d), preforming the pre-judgment of the to-be-inflated microballoon sample; (e), performing the pre-judgment of glue preparation and glue placement positions; (f), performing the vacuum pumping, glue hanging test of the tips of the dispensing wires, the inflation of an inflation room and the balancing; (g), performing the micropore glue sealing; (h), performing the glue solidifying, and performing the detection of the gas in the microballoon. The device provided by the invention can complete the high-quality dispensing hole-sealing of the microballoon, and achieves the quick inflation of a hollow microballoon. The inwards inflated microballoon prepared through the method is good in gas retraining performance, is small in glue sport, and is high in strength of a glue-sealing point.

Description

technical field [0001] The invention belongs to the field of microsphere inflation, and in particular relates to a microsphere semi-automatic dispensing and sealing device and method. Background technique [0002] In laser inertial confinement fusion (ICF) experiments, loading gaseous fuel into microspheres is generally called gas filling. Microsphere inflation mainly includes four methods: thermal diffusion inflation, ball in-situ inflation, injection method inflation and inflation tube inflation. After the microspheres are perforated, in a gas-filled environment, the inflation inside the ball is achieved by dispensing and sealing the holes, which is a method of injection inflation. Ball, and a microsphere inflation method developed. For example, microspheres with general gas barrier properties (such as glass microspheres) are inflated with molecular gas and microspheres with better gas barrier properties (such as metal microspheres) in the material itself. The Chinese i...
