AI Technical Summary
Because the traditional curved microlens array surface shape detection device usually can only shoot at a smaller position directly below because the detection lens is fixed, resulting in only few curved microlenses being detected at a time, making it difficult to improve batch detection efficiency.
A curved microlens array surface shape detection device including a housing, a rotating disk, a motor, a transmission mechanism and a limiting mechanism is designed. The rotating disk is driven by the motor to rotate, so that the detection camera can move along the screw, so that the workbench can be placed on each Take the position to increase the number of detections; at the same time, adjust the starting position of the camera by pulling the plug-in rod to reduce empty stroke and improve efficiency.
The simultaneous detection of multiple curved microlenses is achieved, which significantly improves the efficiency of detection work, and reduces empty stroke when the microlenses are not placed for a long time, improving work efficiency.
