Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

A metal member that is light-transmitting and water-impermeable as shown in fig. 1-3, comprising,

a metal piece 1;

the diameter of light trap 2 is less than 0.01mm, light trap 2 is a plurality of, forms the array.

If the hole is too large, although the light transmission is better, but water leakage is easy, and the size of the light transmission hole can be adjusted according to the amount and pressure of water, in general use, the diameter of the hole is 0.003mm, which is both light transmission and water leakage prevention.

The metal piece 1 is provided with a perforated layer 3, the thickness of the perforated layer 3 is smaller than or equal to 0.8mm, and the light holes 2 are formed in the perforated layer 3.

Wherein, the thickness of the perforation layer 3 is more than or equal to 0.3mm and less than or equal to 0.5 mm.

Wherein, the diameter of the light hole 2 is 0.001mm to 0.005mm, and the interval of the plurality of light holes 2 is 0.005mm to 0.02 mm.

The diameter of the light hole 2 is 0.003mm, and the distance between the light holes 2 is 0.01 mm.

Wherein, a plurality of the light holes 2 form characters or patterns.

Wherein, the light hole 2 is abutted with the LED lamp.

Wherein, still include the following step:

Wherein the thickness of the perforation layer is more than or equal to 0.3mm and less than or equal to 0.5 mm;

the laser drilling is specifically nano-scale particle flow laser drilling, and 0.6Mpa-1.0Mpa nano-scale inert particle flow flows along the direction of an ultraviolet laser beam; wherein the nanoscale inert particle flow is nanoscale inert nitrogen flow or nanoscale titanium particle flow; when the nanoscale inert nitrogen flow is used, the particle flow carries away heat and passivates the particle flow with the hole wall to form nitride; when using nanometer titanium particle to flow, the particle flows and takes away heat and form a layer of metal film simultaneously, because the light trap diameter that the laser technology that the scheme of patent that application number is CN202011077677.7 used matches, 0.05mm diameter is permeable to water in fact, through the experiment, the light trap needs to be less than 0.01mm can have the waterproof nature of not showing permeable to water, and when reaching 0.005mm, whole metalwork rests in the aquatic, can not intake, and when the diameter is greater than 0.001mm, can have good light transmissivity, consequently application number is CN 202011077677.7's patent has covered other material layers at the pore face, make originally can permeate water the non-permeable hole of light transmission become the non-permeable hole of light transmission, and this application cooperates nanometer particle to flow laser to punch, in suitable aperture, can be in the hole that can be in the light transmission and waterproof.

The metal is manufactured and machined to certain thickness by laser technology to form required pattern, character, etc. on the inner surface or other surface of metal product or metal plate. The laser trace cannot be seen on the surface of the metal product or the metal plate, and the processed characters, patterns and the like can be displayed only under the irradiation of a light source (a natural light source or an LED lamp or other light sources after electronic energization), so that the consistency and the attractiveness of the appearance are not influenced.

The surface pattern of the present metal product is generally performed by laser engraving, silk-screen printing and milling. In certain environments, the appearance of the product and the complexity of the process are affected. Therefore, the invention is completed by adopting the laser nano-processing technology on the processes of laser engraving, carving, silk-screen printing and milling which are not necessarily adopted, achieves the consistency and the aesthetic property of the required surface of the product, and is particularly suitable for small electronic products.

The requirements of the metal material products are as follows:

the plate surface thickness is consistent, and the data is as follows: 0.3MM is greater than or equal to, less than or equal to 0.5 MM;

if the product needs surface treatment, the effect needs to be consistent, otherwise, the effect is influenced;

if the product needs surface treatment, the laser drilling process is placed in the last step as far as possible;

the hole spacing was 0.01MM and the hole size was 0.003 MM.

The technology has wide application, for example: the billboard, the LOGO and the LED lamp display products, the surface damage of the products is not needed to be processed, and the cost can be reduced, so that the desired effect is achieved, and the cost is reduced, for example, silk-screen patterns, characters and LOGO except for manufacturing of films and printing ink and the like.

Taking a storage product as an example: the PCBA board is encased in a hardware housing (the LED lamps are in a light-transmissive position corresponding to the housing). After the (data transmission) power-on interface is connected, the LED lamp on the PCBA is turned on, so that the internal light source irradiates from the light-transmitting position and is displayed on the surface of a product under the action of light according to the processes of characters, patterns and the like during processing.
