Description

Pneumatic nozzle roller rotating device

The invention relates to a pneumatic nozzle roller rotating device, in particular to a non-contact method for leveling materials, and the thickness of the coated material can be controlled to a micron level, which is beneficial for subsequent three-dimensional production on the drum. The micro-structure is an innovative designer of the pneumatic nozzle-roller device that achieves the manufacture of the roller mold and the utility model is more practical and useful in its overall application.

According to the current soft electronics industry, the most ideal process is the roll printing process, and how to apply a uniform film on the drum is the key technology for making the mold. The following are known in the following ways: Slot Die, roller-to-roller coating, blade coating, etc.;

1. Please refer to the US Patent Publication No. 2006/0102036 A1 published on May 18, 2006, which is a slit coating method for controlling the flow rate of liquid paint and the size of the slit outlet to achieve control coating. The thickness of the cloth material; however, this method is not conducive to the production of the roller mold because of its high technical threshold and high price.

2. Please refer to the 577360 "Coating Uniform Device" patent case published on February 21, 1993, which includes: a pressure mechanism, a scraper mechanism, and a coating mechanism: a pressure mechanism that generates the power of pushing The source pushes against the scraper mechanism to control the contact pressure between the knife mechanism and the coating mechanism; the scraper mechanism is pushed by the pressure mechanism at one end, and the other end is The coating mechanism is in contact, and the force of the pressure is applied to control the thickness of the film to adhere to the surface of the coating mechanism; the coating mechanism is in contact with the blade mechanism, and is rotated and rolled to adhere the chemical film to the surface, and is rolled. The workpiece is pressed to uniformly apply the chemical film to the surface; however, this method has been found to be incapable of achieving several micron-sized films, and its uniformity is difficult to control.

3. Please refer to the U.S. Patent No. 5,755,883 issued to the U.S. Patent No. 5,755,883, issued on May 26, 1998, which is a roller-to-roller coating method in which two rollers are in contact with each other, and one of the rollers is half-immersed in a liquid paint. Then, the rotating roller uses the viscous force of the liquid paint to bring the coating to another roller to achieve the coating action. However, the above method also adjusts the thickness of the coating by the spacing, and the method is combined with the blade coating method. With the same drawbacks, it is impossible to achieve film thicknesses of several micrometers.

4. See the U.S. Patent No. 5,582,868 issued to theU.S. Patent No. 5,582,868, the disclosure of which is incorporated herein by reference. Disadvantages, the thickness can not be precisely controlled to a few microns, and the material of the blade must be carefully selected, the specific material properties can easily cause the surface of the film to form wrinkles.

In view of this, the inventor has invented a research and improvement of the existing structure based on the rich experience in design and development and actual production of the relevant industry for many years, thus inventing a pneumatic nozzle roller rotating device to achieve better practical value. The purpose of sex.

The pneumatic nozzle roller rotating device of the present invention is mainly provided with a rotating power source on one side of a machine, and the rotating power source can fix the workpiece to be coated, and On the other side of the machine, a flat high-pressure gas nozzle is arranged corresponding to the workpiece fixed on the rotating power source, and a workpiece nozzle is arranged on the machine corresponding to the workpiece fixed on the rotating power source, so that the rotary power source can be controlled. Driving the workpiece to rotate, so that the material nozzle sprays the coating material on the workpiece and the high-pressure gas is sprayed from the flat high-pressure gas nozzle, and the high-pressure gas sprayed by the flat high-pressure gas nozzle pushes the coating material sprayed on the surface of the workpiece. And rotating the workpiece to rotate the workpiece to uniformly coat the surface of the workpiece; thereby, the material can be leveled in a non-contact manner, and the thickness of the coated material can be controlled to a micron level. It is advantageous for the subsequent production of a three-dimensional microstructure on the drum to achieve the production of the roller mold, and more practical performance characteristics in its overall application.
