Defect sorting device of tracking coil for optical pickup actuator

摘要

This high case is about the bad screening device (10) of the track coil of the optical pickup.The upper part forms a rectangular protrusion with protrusions, and the middle part has a plate (5) and a fixed pin (3) attached vertically.According to the fixing support of the fixing pin (3) of the above version (5), the electrodes (6, 7) are respectively pasted on the contact surface of the contact lens unit (H) and combined into the fixing paper clip (9) of the plate spring (8) to form the electrodes (6). The wire (W) connected with 7) is connected with the testing tool, the directionality of the track coil (T) attached to the focus (f) of the contact lens box (H) is set outside, and the abnormal oil (T) of the tone coil (T) can be identified quickly.
