As is well known, plating, etching and the like are achieved by a chemical reaction. Therefore, in order to increase the speed of the plating process and the etching process, the chemical reaction must be promoted.

Means for accelerating this chemical reaction include:
For example, in the case of electroplating, there is a means for increasing the voltage, but supplying a new plating solution and etching solution to the vicinity of the work at all times is also an effective means for promoting the chemical reaction.

In the present invention, a plating solution, an etching solution or the like is sprayed at a high speed and applied to a work to supply a new solution to the work surface at all times, thereby promoting a chemical reaction. And, further, a liquid containing pressurized air is adopted, the liquid in the pressurized air is jetted into contact with the work, and the old liquid adhering to the work surface is forcibly removed by rupture,
It constantly supplies new liquid, which promotes the chemical reaction.

As described above, according to the present invention, a new solution is constantly supplied to the surface of a work to promote a chemical reaction. Therefore, the work surface treatment such as plating and etching can be speeded up.
The goal is to achieve efficiency.

Next, the operation of the present invention will be specifically described.

[0011] Since the pressurized liquid is sucked and introduced into the main body by the suction force of the air passing through the slit from the storage portion stored and held at a constant pressure, the injection from the injection portion is not intermittent, and therefore, The pressurized liquid is sprayed uniformly on the work surface.

In addition, since the direction of the air is regulated by the air passage section , the injection from the injection section has a clean narrow linear injection trajectory. It becomes possible to inject the liquid accurately.

1 to 8 show one embodiment of the present invention, which will be described below.

This embodiment is a nozzle body 2 used when performing various surface treatments of a workpiece 1 involving a chemical reaction such as a plating process and an etching process.

A thin plate-shaped main body 3 capable of holding the inside at a constant pressure is provided.

A slit 4 (L in FIG. 2 is about 3 mm) is provided in the main body 3. The slit 4 is divided on the way, and a small hole 5 (diameter: about 1.5 mm, pitch: about 4 mm) as an air passage section 10 is juxtaposed in the division, and the upper slit 4 is divided. ′ And the lower slit 4 ″ are communicated by the small hole 5.

The main body 3 can be manufactured very efficiently if it is formed by superimposing a plate material in which a concave portion serving as the slit 4 and a semicircular concave groove serving as the small hole 5 are formed.

Separately from the main body 3, a pressurized air supply unit and a liquid supply unit for supplying a pressurized liquid of a predetermined pressure, for example, a plating liquid (molten metal liquid) and an etching liquid (acid) are provided. The pressurized air supply unit is communicated with the upper slit 4 ′ through the communication passage 6 and the communication hole 12, and the liquid supply unit is formed on the back surface of the main body 3 through the introduction path 8 to have a width of the main body 3. The storage portion 9 is communicated with the lower slit 4 ″ at a position near the lower end opening (spout port) of the small hole 5. The pressurized liquid circulates and moves at a predetermined pressure from the introduction path 8 to the storage section 9 and then to the outlet port 11, and the inside of the storage section 9 is maintained at a constant pressure.

Since the present embodiment has the above configuration, the pressurized liquid (pressure 1.0 to 2.0 k) is supplied from the liquid supply unit to the storage unit 9 on the back surface of the main body 3.
g / cm ² ), and pressurized air (pressure 0.5-4.0 kg / cm ² ) is supplied to the slit 4 from the pressurized air supply unit through the communication path 6 and the communication hole.
When introduced through 12, the pressurized air sucks the pressurized liquid in the storage section 9, and the pressurized liquid is accelerated in the lower slit 4 ″ and jetted from the jetting section 7.

The injection from the nozzle body 2 according to the present embodiment is not intermittent for the following reason, and is an injection of a narrow straight line with a fine injection trajectory.

Since the pressurized liquid sealed in the storage section 9 is drawn in with a predetermined pressure by the suction force of the air, the injection from the injection section 7 is not intermittent, but is performed smoothly and continuously. Become. That is, since the pressurized liquid is maintained at a constant pressure, the pressure balance does not collapse, and therefore, the injection is not intermittent. When the pressure of the pressurized liquid is increased, the body 3
The pressurized liquid is pushed into the inside, but even in this case, the pressure of the pressurized liquid is kept constant and the pressure balance is not broken, so that the injection is not intermittent.

For the following reason, the injection trajectory becomes a narrow linear injection.

(I) Since the small holes 5 are arranged in the middle of the slit 4, the directionality of the air is clearly regulated by the small holes 5, and the air whose directionality is clearly regulated, that is, small air in the drawing, The air jetted right below the hole 5 then sucks the pressurized liquid, passes straight through the slit 4, and is jetted from the jetting unit 7, so that it is jetted in a narrow straight line without spreading on both sides and back and forth. Will be done.

(Ii) This embodiment is different from a structure in which a plurality of nozzle bodies are juxtaposed to obtain a narrow linear injection trajectory. A small hole 5 is provided in the middle of the slit 4, and after exiting from the small hole 5, Slit 4
In this case, the injection is made to interfere in advance, and then accelerated and injected, so that the injection trajectory has a very fine narrow straight line.

In this embodiment, the pressurized liquid is sucked from the storage section 9 and then accelerated. The air supply section is formed as one pipe, the injection section is formed as a slit, and one air supply pipe is used. Since the configuration is not such that the pressurized liquid is jetted, the jetting of the liquid becomes uniform, so that the nozzle body has a uniform processing ability.

As described above, in this embodiment, since a new pressurized liquid is constantly supplied to the work surface, the chemical reaction relating to the surface treatment of the work 1 such as the plating process and the etching process is promoted. In addition, since the nozzle body 2 according to the present embodiment can perform an etching process and the like, the spray is not intermittent, and the nozzle body 2 presents a clean narrow spray trajectory. The liquid can be sprayed accurately and uniformly. Therefore, according to the present embodiment, it is possible to form a uniform plating layer accurately and quickly, and to perform an etching process capable of promptly making the corrosion amount a desired amount and making it uniform.

Further, since the nozzle body 2 according to the present embodiment is a nozzle body 2 having a predetermined width, it is particularly effective when the work 1 is wide. For example, if it is a normal injection nozzle,
When one injection nozzle is used, the nozzle must be moved appropriately, and if the movement of this nozzle is troublesome, a plurality of nozzles must be used side by side. With the nozzle body 2 according to the present embodiment, such a complicated problem can be avoided.

Further, in this embodiment, even when the shape of the work 1 is irregular as shown in FIGS. 5, 6, 7, and 8, for example, it is possible to form the injection unit 7 according to the shape of the work 1. That makes the nozzle body excellent in practicality.

Reference numeral 13 denotes a work transport belt.
