写在前面 Intro
这里写一些详细的作品经历，可能会有一些很不完善的。
Here are some detailed work experiences, which may be incomplete.
这部分内容主要是和机械设计、结构设计相关的内容。
This part mainly demonstrates my mechanical work.
气动步进马达 Pneumatic step motor
在核磁共振强磁场强电场下工作运动动力源，需要满足 MRI 安全条件，不能使用金属材料。并提供较高精度控制与大输出力矩。
To work as a motion source under the strong magnetic and electric fields, it is necessary to meet the safety conditions of MRI, which means that metal materials cannot be used. Additionally, it should provide high-precision control and large output torque.
材料：树脂、碳纤维、赛钢 POM
Materials: Photosensitive resin, carbon fiber, and POM.
行星减速器齿轮使用POM材料制作，自润滑耐磨
Planetary gearbox gears are made with POM material, which is self-lubricating and wear-resistant.
Pneumatic stepping principle
Planetary retarder part
磁吸式桌面灯 Magnetic table light
顶盖使用透明材料3D打印，毛玻璃散射效果。
The top cover is 3D printed using a transparent material with ground glass scattering effect.
侧边使用白色光敏树脂打印。
The sides are printed in white photosensitive resin.
同时增加菲涅尔凹透镜来向外折射光线，增加灯光照射区域范围。
At the same time, the Fresnel concave lens is added to refract the light outwards and increase the range of the illuminated area.
