Description

Technical Field

[0001] The invention relates to the technical field of welcome pedal production, in particular to a method for preparing a welcome pedal combined with an etching process. Background Art

[0002] Welcome treads are common components in automotive decoration and industrial equipment, and their performance and appearance directly impact the user experience and the image of the device. Traditional methods for manufacturing welcome treads often rely on stamping and engraving techniques, which have numerous limitations. Stamping processes struggle to achieve complex and detailed designs, and mold costs are high and flexibility is limited. Engraving processes are inefficient and struggle to meet the demands of large-scale production. Therefore, those skilled in the art have proposed a method for manufacturing welcome treads that incorporates an etching process to address the issues raised in the background art. Summary of the Invention

[0003] The object of the present invention is to provide a method for preparing a welcome pedal combined with an etching process to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A method for preparing a welcome pedal combined with an etching process comprises the following steps:

[0006] Step 1: Material selection and planning

[0007] Use 304 stainless steel or 6063 aluminum alloy plate as the substrate material, and the plate thickness is controlled at 1.5-3mm;

[0008] Step 2: Cutting and pretreatment

[0009] Use a high-precision laser cutting machine to cut the metal sheet. Soak the cut substrate in an alkaline degreaser solution for 15-20 minutes, rinse with clean water, and then pickle in a 5% dilute hydrochloric acid solution for 3-5 minutes. Finally, rinse with clean water and dry.

[0010] Step 3: Resist coating

[0011] Use roller coating to coat dry film photoresist on the substrate surface with a coating thickness of 8-12μm, and bake at 70-80℃ for 15-20 minutes after coating;

[0012] Step 4: Exposure and Development

[0013] The pattern film is covered on the substrate coated with the resist layer and exposed in a UV exposure machine at 80-100mJ / cm 2 Expose for 10-15 seconds at an exposure intensity of 10-15 seconds, immerse the substrate in a 2-3% sodium carbonate solution after exposure, and develop at 30-35°C for 3-5 minutes;

[0014] Step 5: Etching

[0015] Place the developed substrate into the etching machine. If it is a 304 stainless steel substrate, use a mixed etching solution with a concentration of 350-400g / L of ferric chloride and a concentration of 5-8% hydrochloric acid. If it is a 6063 aluminum alloy substrate, use a sodium hydroxide etching solution with a concentration of 80-100g / L. The etching solution temperature is maintained at 40-50°C and the etching time is 10-30 minutes.

[0016] Step 6: Demolding

[0017] Immerse the etched substrate in a 10-15% sodium hydroxide stripping solution at 50-60°C for 5-8 minutes, then rinse with a high-pressure water gun;

[0018] Step 7: Surface treatment and post-processing

[0019] The etched pedals are brushed, aluminum alloys are anodized, and stainless steel is passivated. The pedals are bent using a stamping machine, and rubber anti-slip strips are installed on the edges of the pedals. If LED light strips are required, slots for the light strips are reserved on the baseboard and wired for connection.

[0020] Step 8: Quality Inspection and Packaging

[0021] Carry out appearance inspection, size inspection, and performance inspection. If qualified, wrap it with pearl cotton or bubble film, put it in a carton filled with cushioning material, and attach product instructions and quality certificate.

[0022] Furthermore, the alkaline degreasing agent solution is used for soaking to remove oil stains on the surface of the substrate, and the acid pickling is used to remove the oxide layer on the surface of the substrate.

[0023] Furthermore, the anti-etching layer is baked after coating to solidify the photoresist, thereby forming a dense anti-etching layer that protects the part of the substrate that does not need to be etched.

[0024] Furthermore, in the exposure and development steps, the light-exposed portion of the resist layer undergoes a photopolymerization reaction, and the unexposed resist layer is dissolved and removed in the developer, forming a resist layer pattern consistent with the film pattern.

[0025] Furthermore, in the etching process, the etching solution composition, temperature and etching time are controlled to ensure that the accuracy and depth of pattern etching meet the design standards.

[0026] Furthermore, the stripping treatment uses a sodium hydroxide stripping solution to dissolve the anti-corrosion layer, and a high-pressure water gun is used to rinse and remove residual debris.

[0027] Furthermore, in the surface treatment and post-processing steps, wire drawing treatment enhances the texture and anti-slip performance of the pedal, anodizing or passivation treatment improves the corrosion resistance of the pedal, and installation of rubber anti-slip strips enhances safety in use.

[0028] By adopting the above technical solution,

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. By combining etching process with exposure and development technology, complex patterns can be accurately presented to meet diverse design requirements. Surface treatment processes (anodization and passivation) for different materials can significantly improve the corrosion resistance of the pedals in various environments and extend their service life. The parameters of each step are clear. By controlling the etching solution composition, temperature, time, etc., the accuracy and depth of the pattern etching are ensured to meet the design standards. At the same time, the standardized process ensures the stability of production efficiency and product quality.

[0031] 2. The brushed finish and installation of rubber anti-slip strips effectively increase the friction of the pedal surface, reducing the risk of users slipping. The reserved LED light strip installation slot can improve safety and aesthetics for nighttime use. The various processing steps are closely coordinated, and standardized processes and parameter controls are used to improve production efficiency, reduce scrap rates, and facilitate large-scale production.
