AI Technical Summary
Existing CIS cameras struggle to achieve efficient and accurate focusing when dealing with industrial products of varying thicknesses and the offset caused by vibrations during production, resulting in time costs and accuracy losses.
The design employs a coordinated vertical drive mechanism and a horizontal movement mechanism, combined with a limit guide mechanism and an adjustable camera clamping mechanism. Precise two-dimensional positioning control of the CIS camera is achieved through a stepper motor and lead screw transmission structure. With the help of flexible pads and dual optical axis support, the stability and accuracy of the camera during movement are ensured.
It achieves high-precision image acquisition with CIS cameras, reduces vibration interference and swaying issues, improves the versatility of the device and the efficiency of autofocus, extends the service life of the equipment, and ensures the quality of scanned images.
