Technical Field

[0001] The utility model relates to the technical field of electronic equipment, and more specifically to a waterproof, dustproof and light-transmitting metal plate structure. Background Art

[0002] A touch display panel is a device that integrates touch sensing and display functions.

[0003] In modern technology, touch display panels continue to develop and innovate, bringing great convenience and efficiency improvements to people's lives and work.

[0004] Electronic door locks, touch-type elevator controllers, etc. used in daily life all use touch display panels. Existing touch display panels are more or less formed by plastic or glass processing. When in use, it is necessary to apply a film or glass to the surface to reduce direct contact with the panel, reduce panel wear and reduce panel aging speed. However, this method cannot make the panel well wear-resistant, waterproof and dust-proof after the film or glass is applied. Moreover, the surface of the film or glass will be scratched and become blurred after a long period of use, thus resulting in unclear display of the panel.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0009] Preferably, the hole pitch of the plurality of micro through holes is between 0.1 mm and 0.3 mm.

[0010] Preferably, the plate body is made of metal plate.

[0011] Preferably, a light-transmitting, waterproof and dust-proof electric adsorption layer is provided on the surface of the plate body and the surface of the wear-resistant coating.

[0012] The utility model has the following beneficial effects:

[0013] 1. The metal surface material made of aluminum as the base material makes the panel more rigid and corrosion-resistant, and has a certain heat dissipation effect, which greatly improves the service life of the touch display panel and the protection of the movement;

[0014] 2. The touch display panel is formed by filling μm-level holes with translucent, waterproof and dustproof electric adsorption materials.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] A metal plate structure that is waterproof, dustproof and light-transmissive, such as Figure 1 and Figure 2 As shown, it includes a plate body 1 made of aluminum plate as the base material, the plate body 1 is provided with a groove 2, a plurality of micro through holes 3 are arrayed in the groove 2, an acrylic layer is provided on the outer surface of the plate body 1, and the micro through holes 3 are filled with acrylic acid.

[0020] Embodiment: Preparation of a waterproof, dustproof and light-transmitting metal plate structure

[0021] 1) A plate body 1 is made of metal as a base material in a processing plant, and a groove 2 is formed at a portion of the plate body 1 where a touch display is required, so that the thickness of the touch display portion is in the range of 1mm-5mm; the metal plate in the above steps can be made of conductive metal materials such as aluminum plate, steel plate, copper plate, SPCC, etc.;

[0022] 2) The plate obtained in step 1 is coated on the surface of the plate body 1 by anodizing to change the color and surface characteristics of the metal plate; the anodizing forms an oxide film on the metal surface through an electrochemical reaction, and the oxide film can make the surface of the plate body 1 have good corrosion resistance, high hardness and wear resistance, good thermal conductivity, and rich surface color;

[0023] 3) The plate body 1 obtained in step 2 is processed by laser processing to form a group of holes penetrating the coating at the groove 2 formed by the thickness reduction process, wherein the hole spacing is 0.1 mm-0.3 mm and the hole diameter is 5 μm-50 μm;

[0024] 4) The plate body 1 obtained in step 3 is placed in a solution with a concentration of 30% to 70% of a light-transmitting, waterproof, and dust-proof electrical adsorption material as the base, and a DC voltage of 10 to 110 V is applied to the solution and the plate body 1, wherein the plate body 1 is connected to the positive electrode and the solution is connected to the negative electrode, and the plate body 1 is immersed for 60 to 180 seconds after power is applied; the light-transmitting, waterproof, and dust-proof electrical adsorption material is made of highly light-transmitting water-soluble or oil-soluble chemical materials such as acrylic acid, polyurethane, and epoxy resin;

[0025] 5) The plate body 1 obtained in step 4 is placed in an oven at 100°C-150°C and baked for 100 minutes for curing. The baking temperature and time are adjusted according to the aperture of 3, and finally a waterproof, dustproof and light-transmitting metal plate is obtained.

[0026] The metal panel processed by the processing method is thickened at the touch display so that the thickness is between 1mm and 5mm, and then a light-transmitting effect is formed at the thickened part through a group of μm-level holes, and then a light-transmitting, waterproof and dust-proof electric adsorption layer is electrochemically reacted on the surface of the metal panel and in the micro-through holes 3, thereby improving the corrosion resistance and wear resistance of the metal panel after electrification. The coating on the surface of the plate body 1 can also be formed by anodic electrophoresis technology or vacuum coating technology, so that a corrosion-resistant, durable and environmentally friendly coating is formed on the surface of the metal plate. It should be noted here that the coating on the surface of the plate body 1, and the coating material can be conductive or non-conductive, which can increase the wear resistance of the panel.

[0027] In summary:

[0028] By using aluminum as the base material for metal surface processing, the panel has strong overall rigidity and good corrosion resistance, and has a certain heat dissipation effect, which greatly improves the service life of the touch display panel and the protection of the movement;

[0029] The touch display panel is formed by filling μm-level holes with translucent, waterproof and dustproof electric adsorption materials. The advanced technology makes the service life of the touch display panel reach more than 10 years. It is resistant to heat, corrosion, impact and wear. It can be used in extreme ambient temperatures of -25~170℃. The neutral salt spray test time can reach more than 360 hours, which can provide a better translucent interactive interface for use in extreme environments.
