[0048] According to a first aspect of the present invention, a method for manufacturing a display control panel 13 is provided, such as... Figures 1 to 2 As shown, where, Figure 1 The schematic diagram illustrates the principle of the manufacturing method of the display and control panel 13 according to an embodiment of the present invention. Figure 2 This schematically illustrates a process flow diagram of a method for fabricating a display and control panel 13 according to an embodiment of the present invention. The fabrication method includes multiple processes, as shown below. Figure 1 As shown, Figure 1 The process involves multiple steps to prepare the display and control panel 13. In the first step, a substrate 500 with through holes 501 is prepared. The number of through holes 501 can be one or more. Figure 1 In the first step, there are two through holes 501. However, the number of through holes 501 can be set to four, five, or more as needed. In the second step, a film layer 600 is applied to one side of the substrate 500. This film layer 600 can seal one side of the through holes 501. There can be one film layer 600 simultaneously sealing multiple through holes 501, or multiple film layers 600 can seal at least one through hole 501. When there are multiple film layers 600, their thickness is consistent, facilitating the placement of the film layers 600 onto the platform's working surface and simplifying the processing of the platform's working surface. In the third step, a dispensing device 200 is controlled to fill the through holes 501 with resin material 300. The dispensing device 200 includes at least one dispensing head, which fills the through holes 501 with resin material 300. Figure 1In this process, two dispensing heads are used. Both heads can work simultaneously to fill different through-holes 501 at the same time, or they can work separately to fill different through-holes 501 sequentially. In the fourth step, the resin material 300 inside the filled through-holes 501 is cured by ultraviolet light 400 irradiation, thereby obtaining the substrate for manufacturing the display and control panel 13. These steps are the main steps in the manufacturing method of the display and control panel 13.
[0049] The preparation method will be explained in more detail below.
[0050] like Figure 2 As shown, the method for manufacturing the display and control panel 13 includes:
[0051] S21. Provide a substrate 500 having a through hole 501;
[0052] S22. A film layer 600 is disposed on one side of the substrate 500, wherein the film layer 600 is used to close one side of the through hole 501.
[0053] S23. Control the dispensing equipment 200 to fill the resin material 300 from the side of the substrate 500 away from the film layer 600 into the interior of the through hole 501.
[0054] S24. The resin material 300 inside the through hole 501 is cured to obtain the board material for making the display and control panel 13.
[0055] In S21, the substrate 500 with through holes 501 can be achieved in various ways. The through holes 501 can be processed using mechanical punching, laser drilling, chemical etching, and electrical discharge machining (EDM). Mechanical punching is a common punching method, mainly performed using a stamping press. It is suitable for punching various metal materials, such as steel plates and copper plates. Mechanical punching has advantages such as simple operation, high efficiency, and high precision. Laser drilling is an advanced process that utilizes the high energy and high precision of a laser beam for punching. Laser drilling can achieve punching of micro-holes and fine patterns, and has advantages such as high processing accuracy, high speed, and low heat-affected zone. Chemical etching is a process that removes specific areas from the surface of a material through a chemical reaction, based on the chemical reaction between the material and a specific etching solution. In the etching solution, specific chemical substances can react with the material surface, causing the surface to dissolve or transform into other substances. By controlling parameters such as the composition, concentration, temperature, and etching time of the etching solution, precise etching of the material surface can be achieved. Electrical discharge machining (EDM) is mainly used for processing high-hardness and high-toughness metal materials. It utilizes the principle of electrical discharge to create holes in the material. This process is suitable for small-batch punching tasks with special requirements.
[0056] It is important to note that the substrate 500 is typically a plate-like structure, which can be a rectangular plate, a circular plate, or a racetrack-shaped plate. When the substrate 500 is arranged horizontally, the through hole 501 is arranged vertically, that is, the through hole 501 is perpendicular to the surface of the substrate 500.
[0057] Through holes 501 are processed on substrate 500 by one of mechanical punching, laser drilling, chemical etching and electrical discharge punching. The through holes 501 are arranged in a vertical direction and the walls of the through holes 501 are all arranged in a vertical direction.
[0058] In addition, the through hole 501 here is usually in the millimeter range, and the thickness of the substrate 500 can be from 0.01 mm to 10 mm, such as 0.01 mm, 1 mm, 4 mm, 5 mm, 8 mm, 9 mm or 10 mm, etc. The line spacing of the through hole 501 is from 0.01 mm to 10 mm, such as 0.01 mm, 1 mm, 4 mm, 5 mm, 8 mm, 9 mm or 10 mm, etc. When the through hole 501 has a straight structure, the line spacing of the straight structure is also the line width of the straight line, that is, the width of the through hole 501.
[0059] Optionally, the membrane layer 600 includes one of acrylic film, silicone film, polyurethane film and electrostatic film, which can seal the bottom of the through hole 501, thereby reducing the probability of resin material 300 leaking from the bottom of the through hole 501. Of course, the membrane layer 600 can be made of other materials, which can also play a sealing role.
[0060] Specifically, acrylic films are made from acrylic plastics, an important type of synthetic resin. They possess excellent transparency and optical properties, with high light transmittance exceeding 92%, almost comparable to glass, but lighter, easier to process and shape, and highly weather-resistant. Silicone films are made from silicone. When the silicone has high purity, its light transmittance is also high. When used as a film layer, transparent silicone can be selected to make the film. Besides excellent optical properties, transparent silicone also exhibits high temperature resistance, cold resistance, oxidation resistance, and corrosion resistance. Polyurethane films are made from polyurethane, a high-molecular-weight compound. Polyurethane has a light transmittance exceeding 90% and possesses excellent mechanical properties, chemical stability, and light transmission performance. Electrostatic film is a type of non-adhesive film, mainly made of materials such as PE (Polyethylene) and PVC (Polyvinyl chloride). It relies on the electrostatic adsorption of the product itself to adhere to the item and provide protection. It features high light transmittance, high heat insulation, and strong durability.
[0061] As can be seen from the above, acrylic film, silicone film, polyurethane film and electrostatic film all have good light transmittance. Therefore, the film layer 600 has little impact on the light transmittance of the through hole 501, allowing light to pass through the resin material 300 and the film layer 600 inside the through hole 501 and then pass through.
[0062] Optionally, the substrate 500 includes one of a metal plate, a plastic plate, a wood plate, and a composite board. These materials generally have poor light transmittance, while the resin material 300 inside the through hole 501 has good light transmittance, allowing light to pass through and making it convenient for users to observe the display parameters of the display control panel 13.
[0063] It should be noted that the filling material in the through hole 501 can also be selected from other materials as needed, such as bio-based polymers, natural cellulose and biodegradable polymers.
[0064] Optionally, the resin material 300 here includes at least one of epoxy resin, acrylic resin, polyurethane resin, polyester resin, silicone resin, amino resin and acid alcohol resin. These resin materials 300 or mixtures of different resin materials 300 can be selected according to the characteristics of different resin materials 300 as needed.
[0065] Epoxy resin is a high molecular polymer containing two or more epoxy groups in its molecule. It is usually produced by the polycondensation reaction of epichlorohydrin with bisphenol A or polyols. The main characteristics of epoxy resin include high strength, high wear resistance, corrosion resistance, high temperature resistance, excellent insulation properties, good mechanical properties, simple processing, and environmental safety. Epoxy resin not only has excellent adhesion and mechanical strength, but also can remain stable when subjected to large pressure and impact.
[0066] Furthermore, epoxy resin has high surface hardness, good wear resistance, and is not easily worn away. It also exhibits good corrosion resistance to acids, alkalis, salts, and other chemicals. Epoxy resin can withstand high temperatures and has good thermal stability. It is an excellent insulating material widely used in the encapsulation of electronic components. Its processing is simple, employing various molding methods such as injection molding, extrusion, and compression molding. Most importantly, epoxy resin is a recyclable material that does not pollute the environment, aligning with the concept of sustainable development.
[0067] Acrylic resins are polymers produced by polymerizing acrylic acid or acrylic acid derivatives as monomers, or by copolymerizing them with other unsaturated compounds. Acrylic resins possess excellent transparency, strong weather resistance, chemical corrosion resistance, and low cost. Their superior transparency, even surpassing that of glass, is attributed to their colorless, odorless, and non-toxic molecular properties, ensuring they do not affect the color of objects. The stable molecular chains of acrylic resins effectively resist the effects of oxidation, ultraviolet radiation, and other natural factors, making them less prone to aging and yellowing. Acrylic resins are also resistant to corrosion from acids, alkalis, and salts. Compared to other polymer materials, acrylic resins have lower processing costs and simpler production processes, resulting in a relatively lower price.
[0068] Polyurethane resin is a thermoplastic compound composed of diurethane esters. It has the characteristics of high tensile strength, good impact resistance, excellent anti-aging properties, chemical resistance, small size, and light weight.
[0069] Polyester resin is a general term for polymeric compounds formed by the condensation polymerization of diols, diacids, or polyols and polyacids. The main characteristics of polyester resin include good mechanical properties, thermal stability, and chemical stability, as well as excellent heat resistance, chemical resistance, and transparency.
[0070] Organosilicon resins, also known as polysiloxanes, are a general term for polymers whose backbone is composed of alternating silicon and oxygen atoms, with different organic groups linked to silicon atoms. The main characteristics of organosilicon resins include high temperature resistance, low temperature resistance, weather resistance, water and moisture resistance, electrical insulation, good mechanical properties, and chemical stability.
[0071] Amino resins are a general term for resins formed by the condensation polymerization of amino compounds such as urea, melamine or benzomelamine with formaldehyde and alcohols. They have advantages such as high bonding strength, good water resistance and chemical corrosion resistance.
[0072] Alkyd resins, also known as polar resins, are resins made by mixing alkyd and other organic components with collagen. Alkyd resins possess excellent chemical stability, temperature resistance, water resistance, oil resistance, acid and alkali resistance, and thermal shock resistance.
[0073] It should be noted that resin material 300 comes in various types. The resin material 300 in this invention can perform functions such as light transmission, waterproofing, oil resistance, stain resistance, and / or corrosion resistance. When selecting resin material 300, a suitable resin material 300 can be selected based on the function it performs. For example, when good light transmission is required, acrylic resin can be selected; when good waterproofing is required, amino resin can be selected. Other cases will not be illustrated here.
[0074] For the present invention, the substrate 500 is usually selected as a metal plate, wherein the metal plate can be one of galvanized carbon steel plate, stainless steel plate, galvanized aluminum-magnesium plate and aluminum alloy plate. The metal plate can be made by hot rolling or cold rolling processes, and has good surface flatness.
[0075] Optionally, continue to refer to Figure 1 As shown, the cured resin material 300 specifically includes one of the following cured resin materials 300: ultraviolet light 400 curing, heat curing and electron beam curing, to obtain a cured board, which can be used as a raw material for manufacturing the display and control panel 13.
[0076] It should be noted that UV 400 curing, also known as UV curing, is a process that uses UV 400 light to irradiate liquid UV (ultraviolet) curable materials, thus hardening them. The wavelength of UV 400 light ranges from 100 nanometers to 400 nanometers; for example, the wavelength can be 100 nanometers, 150 nanometers, 200 nanometers, 250 nanometers, 300 nanometers, 350 nanometers, or 400 nanometers, etc., and the intensity of UV 400 light can be 10 mW / cm². 2 Up to 2000mW / cm 2 For example, the intensity of ultraviolet light 400 can be 10 mW / cm². 2 50mW / cm 2 100mW / cm 2 200mW / cm 2 500mW / cm 2 1000mW / cm 2 1500mW / cm 2 1800mW / cm 2Alternatively, the curing time for UV 400 can be 2000 mW / cm², ranging from 1 second to 600 seconds. Specifically, the curing time can be 1 second, 10 seconds, 50 seconds, 100 seconds, 200 seconds, 300 seconds, 400 seconds, 500 seconds, or 600 seconds. The curing time of UV 400 is inversely proportional to its intensity; higher intensity results in a shorter curing time, and vice versa. For example, a UV 400 intensity of 100 W / cm²... 2 At that time, the curing time of UV 400 can be 100 seconds, and the intensity of UV 400 is 200 W / cm². 2 At that time, the curing time of UV 400 can be 30 seconds.
[0077] Heat curing is a process that uses heat energy as a catalyst to accelerate the chemical reaction of polymers in hydrogel materials, thereby transforming the hydrogel material from a liquid state to a solid state. The heating temperature and duration of the heat curing process depend on the specific material and process requirements. The heating curing temperature range for resin material 300 is typically between 50-130℃, and the heat curing process varies depending on the type of resin material 300. When determining the process parameters for heat curing, appropriate heating temperature and time should be selected to avoid excessively high or low heating temperatures that could lead to material deterioration or incomplete curing. A suitable heating time should be determined to ensure that the resin material 300 within the through-hole 501 can be completely cured. Secondly, suitable heating equipment should be used and adjusted according to the type of resin material 300 and the size of the through-hole 501.
[0078] Electron beam curing utilizes a high-energy electron beam generated by an electron accelerator to initiate the polymerization or cross-linking of resin material 300, thereby achieving the curing of resin material 300.
[0079] Optionally, in S23, filling the interior of the through-hole 501 with the resin material 300 from the side of the substrate 500 away from the film layer 600 specifically includes the following process:
[0080] The dispensing volume of the dispensing device 200 is determined based on the volume of the through-hole 501. The volume of the through-hole 501 can be obtained by calculation or by measuring the amount of liquid contained in the through-hole 501, which will be explained in more detail later.
[0081] The moving speed and dispensing flow rate of the dispensing head of the dispensing equipment 200 are determined based on the dispensing volume.
[0082] Specifically, the dispensing amount of the dispensing device 200 is determined based on the volume of the through-hole 501. The volume of the through-hole 501 can be obtained through calculation, such as... Figure 3 and Figure 4 As shown, where, Figure 3 A schematic diagram of the structure of the display and control panel 13 according to an embodiment of the present invention is shown. Figure 4 Another structural schematic diagram of the display and control panel 13 according to an embodiment of the present invention is shown schematically. Figure 3 Based on the shape of the through hole 501, it can be divided into two types: a first through hole 5011 and a second through hole 5012. The first through hole 5011 is a circular hole, and the second through hole 5012 is a rectangular hole. The inner diameter of the circular hole is D, and the length and width of the rectangular hole are L and W, respectively. The volume of the first through hole 5011 can be calculated based on the thickness of the substrate 500 and the inner diameter D of the circular hole, thus obtaining the volume of resin material 300 that needs to be filled in the first through hole 5011. In addition, the volume of the second through hole 5012 can also be calculated based on the length L, the width W of the rectangular hole, and the thickness of the substrate 500, thus obtaining the volume of resin material 300 that needs to be filled in the second through hole 5012. Finally, the resin material 300 corresponding to the volume of the first through hole 5011 is filled into the first through hole 5011 using the dispensing device 200, and the resin material 300 corresponding to the volume of the second through hole 5012 is filled into the second through hole 5012 using the dispensing device 200.
[0083] Specifically, the moving speed of the dispensing head of the dispensing equipment 200 is from 0.1 mm / s to 200 mm / s. For example, the moving speed of the dispensing head of the dispensing equipment 200 can be 0.1 mm / s, 15 mm / s, 20 mm / s, 50 mm / s, 100 mm / s, 150 mm / s, or 200 mm / s. The dispensing flow rate of the dispensing equipment 200 is from 0.1 μL / s to 1000 μL / s. For example, the dispensing flow rate of the dispensing equipment 200 can be 0.1 μL / s, 10 μL / s, 100 μL / s, 300 μL / s, 500 μL / s, 800 μL / s, 900 μL / s, 950 μL / s, or 1000 μL / s.
[0084] Continue to refer to Figure 4 As shown, the through hole 501 can also be irregular in shape. When the through hole 501 is irregular in shape, it is difficult to obtain the volume of the through hole 501 by calculation. In this case, the volume of the through hole 501 can be obtained by measuring the amount of liquid contained inside the through hole 501. Finally, the resin material 300 corresponding to the volume of the through hole 501 can be filled into the irregular through hole 501 by the dispensing equipment 200.
[0085] Optionally, the method for preparing the display and control panel 13 further includes placing the substrate 500 having the film layer 600 onto the work platform and making the film layer 600 adhere to the work platform. The process of placing the substrate 500 having the film layer 600 onto the work platform is set before the filling resin material 300 to facilitate the dispensing equipment 200 to fill the through hole 501 with the resin material 300.
[0086] The working platform here can be the ground or a fixed platform structure, so that the substrate 500 with the film layer 600 can be stably placed on the working platform.
[0087] Optionally, the working platform includes an ultrasonic platform, which can vibrate the resin material 300 in the through hole 501 to uniformly fill the through hole 501. At this time, the substrate 500 with the film layer 600 is placed on the ultrasonic platform, wherein the film layer 600 is in contact with the ultrasonic platform; wherein the film layer 600 is connected to the substrate 500, therefore, both the substrate 500 and the film layer 600 are located on the ultrasonic platform and can vibrate accordingly with the vibration of the ultrasonic platform.
[0088] The ultrasonic platform is designed based on the principle of ultrasound. It uses high-frequency mechanical waves to manipulate and process objects. The substrate 500 with the film layer 600 is the object manipulated and processed by the ultrasonic platform. The vibration of the ultrasonic waves acts on the resin material 300 of the through hole 501, causing the resin material 300 to flow and reducing the probability of local defects in the resin material 300 of the through hole 501.
[0089] It is important to note that the ultrasonic platform can vibrate under the action of ultrasound. During the process of filling the through-hole 501 with resin material 300 by the dispensing equipment 200, the ultrasonic platform has the following advantages: First, the vibration of the ultrasonic platform can eliminate air bubbles in the resin material 300, thereby improving the transparency of the cured resin material 300. Second, the vibration of the ultrasonic platform can fully wet the resin material 300 and fill the tiny corners in the through-hole 501, improving the adhesion of the resin material 300 to the inner wall of the through-hole 501, thereby preventing the inner wall of the through-hole 501 from being corroded by air and improving the corrosion resistance of the inner wall surface of the through-hole 501. Third, the vibration of the ultrasonic platform can make the resin material 300 in the through-hole 501 more uniform, reducing the probability of local defects during the curing process and improving the transparency of the resin material 300 inside the through-hole 501.
[0090] Alternatively, the ultrasonic platform may not require vibration, but only need to emit ultrasonic waves. The ultrasonic waves act directly on the resin material 300 inside the through hole 501, so that the resin material 300 can be uniformly filled inside the through hole 501.
[0091] The preparation method of the control panel 13 will be described below with specific embodiments.
[0092] Example 1
[0093] First, take a 0.5 mm thick galvanized sheet as the base material 500. The galvanized sheet has through holes 501 with a width of 1 mm. An acrylic film is attached to the back of the galvanized sheet as a film layer 600. The film layer 600 is located at the bottom of the galvanized sheet and can close one side of all the through holes 501 on the galvanized sheet.
[0094] Then, using a dispensing device 200, acrylic resin material 300 is filled into the through hole 501 from the front side of the galvanized sheet. The dispensing head of the dispensing device 200 moves at a speed of 50 mm / s, and the dispensing flow rate of the dispensing device 200 is 50 μL / s. Here, the front side of the galvanized sheet is the top of the galvanized sheet.
[0095] Finally, the resin material 300 inside the through hole 501 was irradiated with ultraviolet light 400 at a wavelength of 365 nm and an intensity of 1000 mW / cm². 2 The irradiation time is 60 seconds to obtain the cured galvanized sheet.
[0096] Example 2
[0097] First, take a galvanized sheet with a thickness of 8 mm as the base material 500. The galvanized sheet has through holes 501 with a width of 1 mm. An acrylic film is attached to the back of the galvanized sheet as a film layer 600. The film layer 600 is located at the bottom of the galvanized sheet and can block one side of all the through holes 501 on the galvanized sheet.
[0098] Then, using a dispensing device 200, acrylic resin material 300 is filled into the through hole 501 from the front side of the galvanized sheet. The dispensing head of the dispensing device 200 moves at a speed of 50 mm / s, and the dispensing flow rate of the dispensing device 200 is 800 μL / s. Here, the front side of the galvanized sheet is the top of the galvanized sheet.
[0099] Finally, the resin material 300 inside the through hole 501 was irradiated with ultraviolet light 400 at a wavelength of 365 nm and an intensity of 1000 mW / cm². 2 The irradiation time is 60 seconds to obtain the cured galvanized sheet.
[0100] The dispensing equipment 200 here can be a dispensing machine, which can precisely control the dispensing, coating, and filling of fluids on or inside a product surface.
[0101] Whether it is the plate prepared in Example 1 or the plate prepared in Example 2, the resin material 300 can fill the through hole 501 and completely block the side wall of the through hole 501. The amount of resin material 300 overflowing from the through hole 501 is small. It is not necessary to grind the upper surface of the substrate 500 near the through hole 501. Here, the upper surface refers to the surface of the substrate 500 away from the film layer 600.
[0102] Optionally, the substrate 500 is a metal plate. After the through hole 501 is made, the substrate 500 is electroplated so that the inner wall surface of the through hole 501 has a coating. The coating can be a zinc plating layer, thereby reducing the probability of rust appearing on the inner wall surface of the through hole 501.
[0103] A second aspect of the embodiments of the present invention provides a display control panel 13, such as Figure 3 and Figure 4 As shown, the display and control panel 13 is made using the aforementioned method. The resin material 300 is cured. Specifically, the resin material 300 filling the through hole 501 is cured to obtain the board material for making the display and control panel 13. The board material can be machined to make the display and control panel 13 of a specified specification. When the display and control panel 13 is a rectangular structure, the specified specifications include length, width and thickness. When the display and control panel 13 is a circular structure, the specified specifications include diameter or radius and thickness.
[0104] A third aspect of the present invention provides a home appliance 100, which includes the display and control panel 13 mentioned in the above embodiments. The home appliance 100 can be a clothing processing device, a refrigeration device, a water heater, or other similar products. The refrigeration device can be a refrigerator, an air conditioner, or other similar products.
[0105] The display and control panel 13 can be installed on the housing of the home appliance 100 or on the door panel 10 of the home appliance 100, and is used to display the operating parameters of the home appliance or the environmental parameters of the home appliance.
[0106] Figure 5 The schematic diagram shows the structure of a household appliance 100 according to an embodiment of the present invention.
