An　electromagnetic-driven　microgripper　is　designed　for　the　automatic　process　of　gripping　micro-coil　wire　under　the　guidance　of　Stereo　Light　Microscope　(SLM)　visual　system.　The　diameter　of　the　wire　is　about　50-70　mu　m.　Stress　analyze　with　the　ANSYS　simulation　software　helps　to　obtain　stress　and　safety　factor　contours　of　the　upper　and　lower　clamp　arm　when　the　microgripper　grips　wires.　Simulation　results　show　the　correctness　and　reliability　of　the　design.　The　microgripper　clamping　force　is　up　to　0.9　N　by　theoretical　calculation.　Test　results　show　that　this　gripper　achieves　a　displacement　of　1.1　mm.　Functional　test　for　the　wire　traction　microgripper　has　been　done　under　the　guidance　of　SLMvisual　system.　The　wire　traction　microgripper　is　placed　in　three-dimensional　platform,　and　the　three-dimensional　platform　moves　microgripper　in　the　SLM　object　space　close　to　the　clamped　object.　Positioning　accuracy　error　is　determined　by　repeated　positioning　precision　experiments　on　three-dimensional　platform　by　the　laser　displacement　sensor.　Automatic　process　of　gripping　the　micro-coil　wire　is　observed　and　recorded　in　the　SLM　visual　system　to　verify　performance　of　the　microgripper　structure　design.
