2. CNC Machining Stage: Оборудование, Инструменты & Параметры

The CNC machining stage is the core link to realize the prototype structure. The selection of machine tools, инструменты, and processing parameters directly affects the machining accuracy and efficiency.

2.1 Machine Tool & Подготовка инструмента

• Machine Tool Selection: For small-size precision machining of electric mosquito swatter prototypes, small CNC engraving and milling machines (НАПРИМЕР., 3018 Pro) or desktop machining centers are preferred. They are suitable for small workpieces and can ensure high precision.
• Tool Library Configuration:
• Грубая обработка: Flat bottom knife (Φ6-8mm) – quickly removes residual material, improving machining efficiency.
• Отделка: Ball head knife (Φ2-4mm) – engraves mesh details and curved surfaces of the handle, ensuring smooth appearance.
• Сверление/Нарезание резьбы: Center drill and tap – used to machine fixing screw holes, ensuring stable assembly of components.

2.2 Key Processing Parameters by Material

Different materials have different physical properties, so corresponding machining parameters must be adjusted to avoid problems such as material melting or tool wear.

2.3 Зажим & Component Machining Tips

• Методы зажима:
• Ручка: Использовать vacuum suction cups or clamps for fixing to avoid deformation during machining.
• Grid Frame: As a thin-walled component, it needs to be clamped lightly to prevent extrusion deformation.
• Key Component Machining:
• Grid Frame: Усыновить linear interpolation processing to ensure uniform grid spacing (≤ 2mm); perform edge chamfering to avoid scratching the skin.
• Battery Compartment: Machine card slots on the inner wall to fix the battery position; slot the bottom for wire outlet.
• Key Holes: Precisely position the countersinks of the silicone keys to ensure smooth pressing.

3. Пост-обработка & Сборка: Обеспечить качество & Функциональность

After CNC machining, post-processing improves the appearance and performance of components, and scientific assembly ensures the prototype’s functionality and safety.

3.1 Surface Treatment for Components

3.2 Сборные шаги & Safety Testing

Сборные шаги (Linear Narrative):

1. Install the grid frame to the handle and test the grid’s elasticity (no deformation under slight stress).
2. Fix the battery compartment and boost circuit board, then connect the wires (pay attention to insulation to avoid short circuits).
3. Install the battery, and test the switch, indicator light, and high-voltage output (verify with a test pen).
4. Adjust the gap between the grid and the handle (recommended ≤ 1mm) to ensure firmness without loosening.

Safety Testing (Key Points):

• Use a low-voltage power supply to simulate power-up and check if the grid is short-circuited.
• Test the handle’s insulation performance to ensure no leakage.
• Continuously trigger the switch 100 times to check the contact status.

3.3 Quality Inspection Standards

• Функциональное тестирование: Simulate mosquito contact with the grid to verify the high-voltage effect (conduct a safe voltage test to avoid danger).
• Визуальный осмотр: Check the uniformity of gaps, surface scratches, and color consistency of components.
• Проверка размеров: Use a caliper to measure grid spacing and handle diameter (tolerance ± 0.1mm).

4. Оптимизация & Итерация: Улучшить производительность прототипа

To meet market demands, continuous optimization and iteration of the prototype are necessary. This involves structural improvements, material substitutions, and intelligent upgrades.

4.1 Structural Optimization Directions

• Reduce handle weight: Принять hollow construction to reduce material usage while ensuring strength.
• Optimize grid resilience: Add support bars to prevent grid deformation after long-term use.

4.2 Material Substitution & Intelligent Expansion

• Material Substitution: Тест carbon fiber handles (lighter and stronger than aluminum alloy) or POM gears (for noise reduction if there are moving parts).
• Intelligent Expansion: Add USB charging function (convenient for charging) or LED power display (easy to check battery level).

5. Меры предосторожности: Ensure Safety & Control Cost

During the entire CNC machining process, safety and cost control are crucial to avoid accidents and reduce production costs.

5.1 Safety Specifications

• Носить защитные очки during machining to prevent chip splashing and injury.
• When cutting aluminum alloy, must use coolant to cool down to avoid overheating deformation of the material and tool damage.
• During high-voltage testing, operate in accordance with safety regulations to avoid electric shock.

5.2 Расходы & Time Management

• Контроль затрат: Prefer standard tools and universal materials (НАПРИМЕР., use ABS plastic instead of aluminum alloy for handles if performance requirements are not high) to reduce procurement costs.
• Time Management: Adopt phased processing (design → machining → assembly) to avoid long-term occupation of machine tools and improve production efficiency.

Точка зрения Yigu Technology

For CNC machining of electric mosquito swatter prototypes, precision and safety are the core. Yigu Technology believes that in the design stage, it is necessary to fully consider the compatibility of components with CNC machining to avoid rework caused by unreasonable design. In the machining process, choosing the right tools and parameters can significantly improve efficiency – for example, using a ball head knife for finishing the handle’s curved surface can ensure a smooth touch. Кроме того, post-processing and safety testing cannot be ignored; good surface treatment enhances the product’s market competitiveness, and strict safety testing ensures user safety. In the future, with the development of intelligent manufacturing, adding IoT functions (such as remote power control) to electric mosquito swatters will be a new trend, and CNC machining technology will need to adapt to more complex structural processing requirements.

Часто задаваемые вопросы

1. What is the most suitable CNC machine tool for electric mosquito swatter prototype machining?

Small CNC engraving and milling machines (НАПРИМЕР., 3018 Pro) or desktop machining centers are most suitable. They are designed for small-size precision machining, which matches the size of electric mosquito swatter components and can ensure machining accuracy.

2. Why is the grid spacing of the electric mosquito swatter prototype required to be ≤ 2mm?

The main purpose is to prevent mosquitoes from escaping. If the grid spacing is too large, small mosquitoes may pass through the grid and fail to achieve the mosquito-killing effect. В то же время, a spacing of ≤ 2mm can also ensure the safety of users and avoid accidental contact with the high-voltage grid.

3. What surface treatment method is recommended for aluminum alloy handles, и почему?

Anodization (черный/серебристый) рекомендуется. Anodization can form a dense oxide film on the surface of the aluminum alloy handle, which has good corrosion resistance and can prevent the handle from rusting. Кроме того, anodization can also improve the texture of the handle and make the appearance more beautiful, which is more in line with consumer aesthetic needs.
