Production process:

The solar panel frame is the key supporting structure of the photovoltaic module. It is mainly made of aluminum alloy materials and has the characteristics of light weight, corrosion resistance and high strength. The production process can be divided into the following core links:

1. ‌Raw material preparation and profile extrusion ‌

Aluminum alloy selection ‌: Commonly used 6063-T5 or 6061-T6 aluminum alloys must meet the requirements of tensile strength (≥160MPa) and elongation (≥8%).

Extrusion molding ‌: The aluminum rod is heated to 450-500℃ through a mold and then extruded into a profile with a specific cross-sectional shape, followed by air-cooling quenching to increase hardness.

2. ‌Heat treatment and aging strengthening ‌

Aging treatment ‌: The extruded profile needs to be kept in an aging furnace at about 200℃ for 4-6 hours to allow the alloy elements to precipitate evenly and significantly improve the mechanical properties (such as hardness increase by more than 30%).

3. ‌Surface treatment (anodization) ‌

Sandblasting pretreatment ‌: Sandblasting is used to remove surface impurities and increase roughness to enhance the adhesion of the oxide layer.

Anodizing: Electricity is applied in sulfuric acid electrolyte to generate a 15-25μm thick oxide film to improve corrosion resistance (salt spray test can reach more than 1000 hours). Black or other color oxidation can be selected to meet aesthetic requirements.

4. ‌Precision machining‌

Cutting: Use a 45° bevel double-head saw to cut the profile to the required length of the component, with an accuracy control within ±0.5mm.

Punching and slotting: Fully automatic punching machine processes mounting holes and slots (such as the slot design mentioned in the patent for anti-dust accumulation structure).

5. ‌Assembly and quality control‌

Corner fixing: The four corners of the frame are connected by stainless steel corners, and triple inspection is used to ensure verticality and airtightness.

Inspection standards‌: Including dimensional tolerance (such as ±0.2mm), oxide film thickness detection (spectrophotometer), and EL test (check for hidden cracks).

6. ‌Packaging and anti-damage design‌

Film protection: PE protective film is applied to the surface to prevent scratches during transportation.

Interlayer winding: Each frame is separated by a paper interlayer to avoid friction damage. Anti-dust accumulation design: For example, the "guide surface + card slot" structure in Tongwei Solar's patent achieves self-cleaning by optimizing the frame shape, reducing operation and maintenance costs.
