Embodiment Construction

[0061] Below in conjunction with accompanying drawing, the present invention will be further described:

[0062] When the giant magnetostrictive material is subjected to the action of an external magnetic field, the material will produce a magnetostrictive effect, causing the giant magnetostrictive rod to elongate. Therefore, the giant magnetostrictive rod can realize a precise micro-displacement driving process. On this basis, the micro-displacement of the giant magnetostrictive rod is sequentially amplified through the displacement amplification levers at both ends and the diamond-shaped amplification mechanism, and the tungsten wire is driven to pass through the rubber storage barrel filled with glue. The comprehensive effect of surface tension realizes ultra-micro dispensing.

[0063] The invention is an ultra-micro precision dispensing mechanism driven by giant magnetostriction, which takes columnar giant magnetostriction material as the core element. The working princip...

Abstract

The invention belongs to the field of precision driving and ultra-micro-quantity glue dispensing, and relates to an ultra-micro-quantity precise glue dispensing mechanism driven by giant magnetostriction. The ultra-micro precision dispensing mechanism driven by giant magnetostriction, the two ends of the giant magnetostrictive rod are connected with the short end face of the amplifying lever, the long end face of the amplifying lever is connected with the rhombus amplifying mechanism, the upper end of the rhombus amplifying mechanism is connected with the fixed frame, and the rhombus The lower end of the enlargement mechanism is connected with the clamping mechanism, the clamping mechanism is connected with one end of the tungsten wire, and the other end of the tungsten wire is inserted into the rubber storage barrel. The invention is an ultra-micro precision dispensing mechanism based on the giant magnetostrictive material as the core, which can realize ultra-micro dispensing of picoliters or even femtoliters. After amplifying the driving displacement of the giant magnetostrictive rod through a two-stage amplification mechanism, the tungsten wire is driven through the glue storage barrel filled with glue liquid to realize micro-dispensing.

Description

Technical field: [0001] The invention belongs to the field of precision driving and ultra-micro-quantity glue dispensing, and relates to an ultra-micro-quantity precise glue dispensing mechanism driven by giant magnetostriction. Background technique: [0002] The micro-dispensing technology and method in micro-connection / sealing engineering is mainly to absorb, transfer, and distribute micro-liquids. It has a wide range of applications in nuclear fusion experiments and other fields. At present, there are mainly two methods of contact and non-contact. In the contact method, the dispensing head guides the glue to contact the dispensing surface for a period of time, relying on the viscous force between the glue and the substrate and the dispensing. The needle is separated to form glue dots on the substrate; in the non-contact method, a pressure device is used to pressurize the glue to atomize (or droplet) and obtain a certain kinetic energy to spray onto the dispensing surface...
