Problems solved by technology

[0003] The first is to use laser processing to drill holes, and the shortcoming of this existing processing method is that the inner wall of the fine hole 61 is relatively rough, and those who are familiar with this technology, the special ink of inkjet printer, its ink liquid is slightly It tends to be thicker, which greatly improves the viscosity (or adhesion) of the liquid to the rougher contact surface.
Therefore, if the surface of the inner wall of the fine hole 61 for ink jet flow is not fine enough and the precision is not good enough, the resistance to ink flow will be increased virtually, and when the printer is used for inkjet printing with higher resolution , due to the substantial increase in the amount of ink ejected, it is easy to cause the pores 61 of the existing structure to be clogged when the jet flow is not good enough
Secondly, since the laser can only be carried out in a straight line, the fine holes 61 processed can only be vertical walls, and the fine holes 61 with arc surfaces or special geometric shapes cannot be produced, so it is impossible to manufacture special flow channels or hole shapes. microstructure products
[0004] The second existing method is to use copper electroforming micro-holes, but as we all know, laser processing is "optical processing", and the precision must be higher than that of copper electroforming. Copper electroformed micropores still face various processing quality problems such as inaccurate micropore size, poor precision and rough surface. Especially for the processing conditions of micropore diameter less than 50 microns, the existing processing technology is almost impossible to complete.

Abstract

A microstructure manufacturing method combining with photohardening at least includes the following steps: 1. preparing; 2. spraying glue liquid; 3. exposing to ultraviolet light; 4. removing the bottom die. By spraying liquid state glue and solidifying with the ultraviolet radiation, a finished precise microstructure can be obtained. The microstructure can be non-penetrative micro-texture or microstructure, or micro-perforated flake, and can be used for micro-optical lens array, micro-optical diffraction element, ink-jet printer, biological wafer reagent or fuel cell commutation pore or relative nanometer technology. At the same time, the method can make the pores form special geometric shape and greatly reduce the procedure and time of repairing die or correction.

Description

technical field [0001] The invention relates to a microstructure manufacturing method combined with photohardening molding. Background technique [0002] The scientific and technological "noun" of nanometer has become familiar to people in today's era of rapid technological advancement and has a wide range of applications. see figure 1 and figure 2 For example, the nozzle sheet 60 applied to the nozzle of an inkjet printer at the present stage is an example. The nozzle sheet 60 is a three-dimensional rectangle with a length of 7 mm, a width of 4 mm, and a thickness (t) of 50 microns. The nozzle sheet 60 is formed vertically. Several fine holes 61, the diameter (d) of the fine holes 61 is 100 microns, and the hole distance (D) is 100 to 200 microns. Since the diameter (d) of the fine hole 61 is very small, it cannot be completed with the precision of the existing drilling and cutting technology. And except existing cutting technology, existing production method that can ...
