Description

TECHNICAL FIELD

Patent publication No. CN220406368U discloses an optical image screening machine, which belongs to the technical field of screening and comprises a conveying device composed of a conveying belt and a conveying frame body. One side of the conveying belt is provided with an inclined outgoing track. A top cover is arranged above the conveying frame body, and an optical camera is embedded in the inner bottom of the top cover. A computer for image screening is arranged on one side of the top cover, and the computer is connected with the optical camera. Two symmetrical connecting plates are connected to one end of the conveying frame body, and a baffle for blocking workpieces is arranged on one side of the connecting plate. A side plate connected with the conveying frame body is arranged on one side of each of the two connecting plates, and a centering plate for centering workpieces is arranged on one side of the adjacent two side plates. The optical image screening machine can not only realize spacing and height adjustment, but also can center the workpieces, thereby improving the accuracy of optical image detection.

[0003] In the prior art, although the optical image screening machine can be used for the centering plate for centering workpieces, the height of the plate body cannot be adjusted, which cannot adapt to the height adjustment function of the screening machine. When some high workpieces are moved and transported, they may be tilted laterally when the centering plate is used to center the workpieces, because the center of gravity of the workpieces is higher than the height of the plate body. Therefore, the application range of the conveying mechanism for transporting workpieces is limited. In addition, the driving of the centering plate is driven by two motors, so that the two motors must be synchronized during synchronization. The energy consumption is large and the limitation is high, which further reduces the environmental protection and practicality of the conveying mechanism as a whole. UTILITY MODEL CONTENTS
