Description

Technical Field

[0001] The utility model relates to the field of optical screening machines, and more specifically, to a clamping mechanism of an optical screening machine for part sorting and processing. Background Technique

[0002] An optical screening machine is a machine that uses cameras and other devices to check whether the surface of a workpiece is qualified. The patent publication number CN220738584U discloses an optical screening machine for sorting and processing parts, belonging to the technical field of part optical screening. It includes a workbench and a protective box arranged above the workbench. A discharge groove is formed on the surface of the workbench, and a partition is rotatably connected in the discharge groove on the surface of the workbench. Fixing plates are fixed on the outer walls on both sides of the workbench, and the protective box is fixed between the two fixing plates. Two fixing boxes are movably connected to the bottom of the protective box. Rotating shafts are rotatably connected in the two fixing boxes. Fixing frames for fixing parts are fixed on the opposite surfaces of the two rotating shafts. A screening camera for part screening is installed at the bottom of the protective box. This optical screening machine for sorting and processing parts can comprehensively detect parts of different specifications, thereby ensuring the detection accuracy.

[0003] In the existing technology, although the clamping device can rotate and extend, its height position cannot be adjusted, so that the workpiece is restricted by the size of the turning circle during rotation, thus restricting the types of workpieces and reducing the practicality of the device. Moreover, the bottom of the L-shaped clamping plate will block a large area of the surface of the clamped workpiece, affecting its overall optical inspection and further reducing the practicality of the clamping device.
