Description

Technical Field

[0001] The utility model relates to the technical field of visual inspection, in particular to a dust removal structure for a visual module. Background Art

[0002] The screening method of grains includes manual screening. Manual screening uses methods such as winnowing, picking, and sieving. The method of manual selection has problems such as low work efficiency and high labor intensity. Currently, visual modules are used to detect and identify the conveyed grains, and substances such as imperfect grains in the grains are identified, so as to achieve machine screening of grains, which saves more manpower.

[0003] However, during the process of detecting and identifying grains through a visual module, a transparent glass is usually installed below the visual module. But after long-term detection and identification of grains, some dust will be adsorbed under the transparent glass, blocking the picture taken by the visual module and affecting the effect of grain detection and identification. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a dust removal structure for a visual module, which solves the problem that some dust will be adsorbed under the transparent glass, blocking the picture taken by the visual module and affecting the effect of grain detection and identification.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A dust removal structure for a visual module includes a visual recognition box and a bottom plate fixedly installed below the interior of the visual recognition box. The top of the bottom plate is fixedly installed with a transparent glass plate through an opening. Above the transparent glass plate and on the top of the bottom plate, a limiting plate is fixedly installed through a mounting block. One side of the inner cavity of the visual recognition box is fixedly connected with a fixing frame. Inside the fixing frame, a camera is fixedly installed through a fixing block. A circular groove adapted to the camera is opened at the top of the limiting plate. Below one side of the visual recognition box, a connecting frame is fixedly installed. At the bottom of the connecting frame, a cylinder is fixedly installed. The telescopic end of the cylinder penetrates through the visual recognition box and extends below the bottom plate. The telescopic end of the cylinder extending below the bottom plate is fixedly installed with a sliding plate. On the top of the sliding plate, a silica gel plate adapted to the transparent glass plate is fixedly installed through an opening.

[0006] Preferably, sliding rods are fixedly connected between the front and rear parts on both sides of the inner cavity of the visual recognition box and below the bottom plate. At the front and rear parts on one side of the sliding plate, sliding sleeves adapted to the sliding rods are fixedly installed through openings.

[0007] Preferably, one side of the top of the visual recognition box is fixedly connected with a mounting plate.

[0008] Advantageous Effects

[0009] The present utility model provides a dust removal structure for a vision module. Compared with the existing technologies, it has the following

[0010] Advantageous effects:

[0011] The utility model controls the camera to detect and identify the grains below, and regularly controls the air cylinder. The air cylinder drives the sliding plate to move leftward, and the sliding plate drives the silica gel plate to move leftward. When the silica gel plate moves, it passes under the transparent glass plate, so that the silica gel plate sweeps the lower surface of the transparent glass plate, which can well sweep away the dust adsorbed on the lower surface of the transparent glass plate, continuously ensure the transparency of the transparent glass plate, and ensure the clarity of the grain recognition and detection picture.
