Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and more specifically to a visual inspection device for product surface defects. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection involves using machine vision products to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, these signals are converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results.

[0003] Currently, visual inspection devices are commonly used to detect defects on product surfaces. While these devices are capable of inspection, they still have some shortcomings in practical applications. Specifically, they employ a single-direction visual recognition system, which can only inspect the four sides of the product. When the inspection requires the bottom or top surface, workers need to manually flip the workpiece, which slows down the inspection process and reduces efficiency.

[0004] Therefore, there is a need to provide a visual inspection device for product surface defects to solve the problem of low inspection efficiency when the inspection requirements involve the bottom or top surface of the product. Utility Model Content

[0005] The purpose of this invention is to provide a visual inspection device for product surface defects, so as to solve the technical problems mentioned in the background art.

[0006] The present invention adopts the following technical solution:

[0007] A visual inspection device for surface defects of a product includes: a base plate and a control mechanism. The upper surface of the base plate is provided with a housing. The inner wall of the housing is connected to a carrier plate. A transparent plate is embedded in the carrier plate. An annular groove is formed on the upper surface of the carrier plate. A sliding ring is rotatably connected to the annular groove. Two symmetrically arranged first cameras are connected to the upper surface of the sliding ring. A second camera is fixedly connected to both the inner top wall and the inner bottom wall of the housing.

[0008] The control mechanism includes a motor connected to the slip ring to drive the two first cameras to rotate.

[0009] Furthermore, the inner wall of the annular groove is slidably connected with two sets of sliders, the upper end faces of the two sets of sliders are fixedly connected to the slip ring, and the upper end face of the slip ring is fixedly connected with two symmetrically arranged upright plates. The first camera is disposed on one side of the two upright plates that are close to each other.

[0010] Furthermore, the outer side of the slip ring is provided with a meshing part, the bottom surface of the motor is fixedly connected to the inner bottom wall of the housing, the output end of the motor is fixedly connected to a rotating rod, the top end of the rotating rod is rotatably connected to the bottom surface of the carrier plate through a bearing, and the top end of the rotating rod is fixedly connected to a gear, which meshes with the meshing part of the slip ring.

A slip ring 7 is rotatably connected to the annular groove 9. Two symmetrically arranged first cameras 4 are connected to the upper end surface of the slip ring 7. A second camera 6 is fixedly connected to the inner top wall and the inner bottom wall of the housing 2. The control mechanism 5 is provided with a motor 501 connected to the slip ring 7 to drive the two first cameras 4 to rotate.

[0031] The inner wall of the annular groove 9 is slidably connected to two sets of sliders 10. The upper end faces of the two sets of sliders 10 are fixedly connected to the slip ring. The upper end face of the slip ring 7 is fixedly connected to two symmetrically arranged upright plates 8.
