Description

Pen type liquid guiding infiltration device

Technical field

The present invention relates to the field of micro-liquid infiltration devices, and in particular to a pen-type liquid guiding infiltration device.

Background technique

In general, pens cannot draw lines on the surface of flat glass or silicon wafers, and even if they are, they are intermittently irregular.

The distance between the inner pen of the existing pen and the inner ring of the round hoop pen is micron-sized, and its size directly affects most of the micro-liquids to be concentrated in the two grooves.

Between the inner tongue of the ordinary pen and the metal ring of the nib, there is only a tubular gap with a bevel (typically 500-800 μm). When the liquid enters the inner ring and the inner ring of the pen tip from the inner tongue supply hole, Under the action of the capillary function, the liquid will be dispersed to various parts of the inner ring of the metal. The head of the metal nib has an elongated slit of about 300-500 μm wide and is connected to the tip of the nib (the bead head is also two halves). When the ball head is in contact with the work surface (for example, paper), the liquid is left in the place where the ball head passes under the action of wetting and capillary action. Also a capillary action, the inclined tubular liquid will continuously collect into the consumable position (slit) and then continuously supply the ball head from the slit. Then draw continuous lines on the paper you write. However, in general, pens cannot draw lines on the surface of flat glass or silicon wafers, even when they are drawn, they are intermittent and irregular. This is because the bead head and the soft paper surface contact are in surface contact, and it is easy to continuously permeate the ink. When the bead head is in contact with the hard glass and the silicon wafer, it is difficult to have capillary action to continuously bleed out the ink, so that only intermittent ink is left.

In order to make the liquid evenly and continuously on the surface of the glass or silicon wafer, it is necessary to obtain a needle with an actual length of about 3-20 mm (0.8-1.3 mm is the tip of the hair, and the rest is used to concentrate the trace liquid). Into a nano-scale waterline, the nano-scale waterline can be continuously directed to the tip of the needle). However, the current metal is difficult to prepare a needle with good flexibility, so the current ordinary pen can not achieve a continuous line on the hard substrate.

Summary of the invention

In order to solve the above problems, the present invention provides a device for infiltrating a small amount of liquid into the whole of two fiber hairs through a special pen inner tongue infusion guide and two fiber tipping devices, and enables the pen head device to also Regular lines can be drawn on the surface of flat glass or silicon wafers.

Wherein, the pen inner tongue infusion tube 2 is provided with two circular arc-shaped grooves 21 along the outer circumference, and the fiber hair needles 4 are fixed in the circular arc-shaped grooves 21 at the liquid-out end of the tongue infusion tube 2; The inner tongue infusion tube 2 passes through the rounded pen head 3, and the side wall opening of the circular arc shaped groove 21 faces the liquid guiding groove 31 of the inner wall of the rounded pen head 3;

The liquid inlet end of the rounded pen head 3 is fixed inside the liquid discharge end of the water supply pipe 1.

The device according to the invention, wherein the circular arc-shaped recess 21 has a circular cross section with a diameter of 65-100 μm.

The device according to the invention, wherein the two arcuate grooves 21 are between 25 and 50 μm apart.

The device according to the present invention, wherein the rounded pen head 3 cuts off the ball of the pen tip, and the head is flush.

According to the device of the present invention, preferably, the head of the fiber hairpin 4 is 0.8-1.3 mm from the head of the round-tipped pen head 3.

According to the device of the present invention, preferably, the head of the fiber hairpin 4 is not less than 12 mm from the head of the water outlet end of the tongue infusion tube 2.

According to the device of the present invention, preferably, each of the circular arc-shaped grooves 21 incorporates a fiber hair needle 4.

The device according to the present invention, wherein the fiber hair needle 4 may be a polymer hair, a metal hair or any animal hair, and the animal hair may be, for example, one of wolf velvet, sarcophagus and rabbit hair. .

Preferably, the length of the fiber hair needle is a natural length (or about 40 mm), and the thickness is controlled to be 60-80 μm.

The device according to the invention, wherein the other end of the water supply pipe 1 is connected to an automatic liquid supply device.

The fixing manner between the hair needle and the pen head, the pen head and the inner tongue infusion tube, and the pen head and the liquid supply tube of the present invention may be a fixing manner known in the art, and the present invention is not particularly limited as long as it can achieve a fixed purpose. can. For example but not limited to the following:

1. The two arc-shaped grooves of the inner infusion tube of the pen are the original water outlet holes of the inner tongue outlet pipe, so the fiber hair is fixed with glue on the outlet hole. After curing, a nickel-chromium alloy wire with a diameter of about 30 μm is wound around the outer tongue for 10-20 turns. The purpose is to control the distance between the inner tongue infusion tube and the round-nose pen head; b. the wound nickel-chromium wire also has capillary infiltration effect. .

2. Place the inner tongue infusion tube part into the inner ring of the rounded pen head according to the size;

3. When the outermost jacketed liquid supply pipe (for example, ordinary heat shrinkable pipe) is heated, all the components are fixed together.

Because of the ability to spread and infiltrate the liquid between the tip of the pen and the scribing interface, the present invention utilizes this feature to produce a pen-type liquid guiding infiltration device containing a special pen inner infusion guide. The invention solves the problem that the pen tip can also draw lines on the surface of the flat glass or the silicon wafer. The invention innovatively opens the middle of one side of the pen inner infusion guide, firstly opens a rectangular groove on the bottom surface of the rectangular groove. Two micro-circular grooves are symmetrically opened, and one fiber tip is installed in each of the circular grooves. The tip of the hair reveals the original pen tip 0.8-1.3mm. Because the tip of the hair is 0.8-1.3mm longer than the tip of the pen, and the liquid infiltration of the pen itself is very good, the tip of the fiber can draw regular lines on the surface of the flat glass or silicon wafer. According to the requirements of the film layer, the liquid supply can be adjusted to produce an ideal film. In this design, since the pen head device can withstand a small amount of liquid supply change, it can actively adjust a small amount of error in the micro-feeding process, and always keep the film layer consistent. The patented method is simple in principle and easy to implement, and can effectively solve the problem of infiltration of trace liquid in a trace liquid supply system, and is of great significance for the development of experimental research and production of a new type of high-quality ultra-thin film layer.
