Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically to a high-precision visual inspection device for workpieces before they leave the factory. 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] Traditional visual inspection equipment relies on manual placement of workpieces onto the platform before starting the machine. This results in low work efficiency and a single-direction inspection method, which cannot inspect workpieces from multiple angles, leading to low inspection accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-precision visual inspection device for workpieces before they leave the factory. It has a simple structure, realizes automatic loading and unloading, and can perform visual inspection on workpieces passing by in sequence from different angles. It also has built-in counting and identification functions for unloading, with high precision and good effect.

[0005] To solve the above-mentioned technical problems, this utility model provides a high-precision visual inspection device for workpieces before they leave the factory, including a worktable, a feeding assembly on the worktable, a feeding guide plate at the end of the feeding assembly, a feeding through hole on the worktable corresponding to the position of the feeding guide plate, and a feeding conveyor belt at the bottom of the feeding through hole; a support column on the side of the feeding assembly, an upper dovetail slide and a lower dovetail slide on the support column, a main visual inspection device fixed on the upper dovetail slide, a light source fixing plate on the lower dovetail slide, an auxiliary light source at the bottom of the light source fixing plate, and an auxiliary through hole at the center.

[0006] Furthermore, a frame is provided outside the workbench, and openings are provided on the frame corresponding to the positions of the feeding component and the unloading conveyor belt.

[0007] Furthermore, the feeding assembly has two auxiliary bases on the side away from the support column. Each auxiliary base has an auxiliary side plate, a movable plate on the auxiliary side plate, a protective shell on the movable plate, and an auxiliary visual inspection device inside the protective shell.

[0008] Furthermore, a feeding sensor assembly is provided on the worktable near the feeding guide plate, including an adjustable lifting plate and a limiting shaft for limiting the lifting plate.

[0009] Furthermore, a counting sensor component is provided between the unloading sensor component and the loading component.

[0010] Furthermore, both the feeding assembly and the unloading conveyor belt are powered by drive motors.

[0011] The beneficial effects of this utility model are as follows: When using this device, the material is placed in the feeding assembly for feeding. First, the positional relationship between the upper dovetail slide and the lower dovetail slide is adjusted to change the positional relationship between the main vision inspection equipment and the auxiliary light source. After the adjustment is completed, the feeding assembly is used to transport the material to the bottom of the main vision inspection equipment for photographing and inspection. Then, the material is fed through the unloading guide plate and the unloading through the unloading through hole into the unloading conveyor belt to complete the overall operation. The degree of automation is high.

[0012] Meanwhile, by adjusting the position of the auxiliary side plate on the auxiliary base, the distance between the auxiliary vision inspection equipment and the feeding component is changed. Then, the height of the auxiliary vision inspection equipment is adjusted by using the moving plate. By cooperating with the main vision inspection equipment, visual inspection can be performed on the workpieces that pass by in sequence from different angles, and the effect is good.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
