Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a visual inspection device. Background Technology

[0002] Appearance inspection equipment is a tool used to inspect the appearance of products. It mainly uses a camera to take pictures of the product's appearance and analyzes the appearance of the product in the pictures to determine whether there are any defects in the product's appearance.

[0003] However, in existing appearance inspection equipment, a single camera can only capture one surface of the product to be inspected. Therefore, this presents certain difficulties for products with multiple surfaces to be inspected. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an appearance inspection device, comprising a base and a turntable. The base has an L-shaped structure, and a groove for accommodating the turntable is provided at the included angle of the base. The turntable is disposed in the groove. A motor is fixedly installed at the bottom of the base, and the motor drives the turntable to rotate. A vision inspection mechanism is installed at the corner of the base. A first conveying mechanism is provided on one side of the vision inspection mechanism, and a second conveying mechanism is provided on the other side of the vision inspection mechanism. A feeding guide rail is provided at a position opposite to the vision inspection mechanism, and the feeding guide rail is inclined at a 45° angle.

[0006] Preferably, the visual inspection mechanism comprises a track, a slide, a CCD camera mounting base, and a CCD camera. Two tracks are provided and arranged in parallel. The slide is mounted on the two tracks and can move up and down along the tracks. Locking screws are installed on the slide. The CCD camera mounting base is mounted on the inner side of the slide via a pivot. A tensioning screw is provided on one side of the CCD camera mounting base. The CCD camera is mounted in the CCD camera mounting base.

[0007] Preferably, a top plate is fixed to the top of the track, and a supplementary light is installed at the bottom of the top plate.

[0008] Preferably, the first conveying mechanism and the second conveying mechanism have the same structure. The first conveying mechanism consists of an electric push rod mounting base, an electric push rod, and a push block. The electric push rod is mounted on the electric push rod mounting base, and the push block is fixed to the telescopic end of the electric push rod.

[0009] Preferably, the base has a notch on its side that cooperates with the first conveying mechanism and the second conveying mechanism.

[0010] Preferably, a connecting plate is fixed at each of the two discharge ports of the base, and a waist hole is opened on each side of the connecting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device needs to be connected to a computer host for use. During operation, the material slides down onto the turntable via the feeding guide rail. The turntable is driven to rotate by a motor, which in turn causes the material on it to rotate. The vision inspection mechanism can perform multi-faceted visual inspection on the rotating material. The base is provided with two discharge ports. The first conveying mechanism and the second conveying mechanism each correspond to one discharge port. The computer host controls the first conveying mechanism and the second conveying mechanism respectively according to whether the surface of the material is qualified, so as to separate qualified materials from unqualified materials.

[0012] When using the visual inspection mechanism, after loosening the locking screw, the slide can be moved up and down to adjust the height of the CCD camera. After loosening the tightening screw, the CCD camera mounting base can be rotated to adjust the tilt angle of the CCD camera.

[0013] The supplementary lights located at the top of the track can provide illumination, making visual inspection more accurate. Attached Figure Description
