In specific application, the feeding trolley transfers the material tray carrying the workpiece to the loading end of the loading and conveying mechanism 22, at which time, the lower bottom surface of the material tray contacts the loading and conveying roller 221, and then, the loading and conveying driving member 222 generates a driving force to drive the loading and conveying roller 221 to rotate, and the loading and conveying roller 221 transfers the material tray carrying the workpiece to the workstation of the lifting mechanism 23.

[0027] In order to prevent the material tray from continuing to slide forward under the action of inertia, a baffle 211 is provided on the frame 21 , and the baffle 211 blocks the material tray so that the material tray is located at a predetermined position of the lifting mechanism 23 .
