Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to a visual detection device based on an industrial camera. Background Art

[0002] Industrial cameras are also commonly known as industrial cameras. Compared with traditional civilian cameras (camcorders), they have high image stability, high transmission capability and high anti-interference ability. Most industrial cameras on the market are based on CCD (Charge Coupled Device) or CMOS (Complementary Meta-Oxide Semiconductor) chips.

[0003] After searching, the patent document with authorization announcement number CN213021438U discloses an industrial camera visual inspection device for irregular parts. The inspection device includes a base plate, an inspection platform, a lens assembly and a visual assembly. The inspection platform, the lens assembly and the visual assembly are all connected on the same surface of the base plate. The lens assembly includes a lens fixing rod and a lens. The lens fixing rod is connected to the base plate, and the lens is mounted on the lens fixing rod. The visual assembly includes a mounting rod and a mounting seat movably connected to the mounting rod. The mounting rod is fixed to the base plate, and a camera is provided on the mounting seat. The lens is located between the inspection platform and the camera.

[0004] When the above-mentioned detection device is in use, the product to be inspected is placed on the inspection table. After the lens fixing rod fixes the lens in a suitable position, the distance between the camera and the lens is changed by adjusting the movable connection position between the mounting seat and the mounting rod, thereby changing the focal length between the camera and the lens to achieve clear capture of the size of irregular parts. However, if the product to be inspected is directly placed on the inspection table, the industrial camera can only take pictures of the front or back of the product. Since some products need to be inspected on the side during the inspection process, based on the setting of the above-mentioned inspection table, after the front or back of the product is inspected, the staff needs to manually tilt the product so that the side of the product is exposed and facing the camera lens. This reduces the efficiency of the inspection, is time-consuming and labor-intensive, and is relatively inconvenient to use.

[0005] To this end, we propose a visual inspection device based on industrial cameras to solve the above problems. Utility Model Content

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1-6 As shown, a visual inspection device based on an industrial camera comprises a frame 1, with an inspection assembly and a storage assembly disposed at the top and bottom of the frame 1, respectively. The storage assembly is used to support product a, and the inspection assembly is used to visually inspect the top surface of the placed product a. The inspection assembly comprises a slider 8 slidably disposed vertically on the frame 1 and an industrial camera 13. The slider 8 is provided with a horizontally arranged guide rail 9, on which a mounting fixture for the industrial camera 13 is horizontally mounted. Within the two-dimensional motion mechanism formed by the slider 8 and guide rail 9, the industrial camera 13 can move up, down, left, and right above the product a, adapting to different types of product a and achieving adaptability in inspection. Furthermore, the assembly fixture includes a base 10 horizontally slidably mounted on the guide rail 9, and a threaded rod 11 and two clamping plates 12 are movably provided on the base 10, and the threaded rod 11 and the two clamping plates 12 constitute a screw slider mechanism, so that a clamping assembly area with adjustable size is formed between the two clamping plates 12, and the clamping assembly area is used to clamp and fix the industrial camera 13.

[0032] During the inspection process, in order to also visually inspect the side of product a, a storage assembly can be provided, including a horizontally arranged storage plate 2 mounted on the bottom of frame 1, with a telescopic member 3 disposed at the bottom of storage plate 2. The actuating end of telescopic member 3 can extend upward through storage plate 2 and contact the bottom of product a, and this contact point is eccentrically positioned so that when product a is placed on storage plate 2, the actuating end of telescopic member 3 can lift product a upward and expose one side of product a to the inspection range of industrial camera 13. Preferably, telescopic member 3 is configured using conventional technology in the prior art, such as an electric telescopic rod or a pneumatic cylinder.

[0033] In the process of using the execution end of the telescopic member 3 to push the product a upward, in order to prevent the position of the product a from shifting, a baffle 4 can be fixedly provided on the top of the storage plate 2, and when the execution end of the telescopic member 3 pushes the product a upward and exposes one side of the product a, the baffle 4 is used to resist the other opposite side of the product a.

[0034] like Figure 1-Figure 2 As shown, in order to be able to perform visual inspection on different sides of product a, the utility model also includes a lifting assembly, and the telescopic parts 3 and the baffles 4 together constitute the above-mentioned lifting assembly, and the lifting assembly is arranged in multiple groups. Specifically, the multiple telescopic parts 3 in the multiple groups of lifting assemblies are arranged in a circumferential array and form a first virtual circle when viewed from above, and the multiple baffles 4 in the multiple groups of lifting assemblies are arranged in a circumferential array and form a second virtual circle when viewed from above. The first virtual circle is coaxially arranged with the second virtual circle, and the first virtual circle is located within the second virtual circle. When the corresponding telescopic parts 3 are used to lift the product a, the corresponding baffles 4 can limit and block the product a so that the position of the product a remains stable.

[0035] There are several options for setting the number of lifting components:

[0036] (1) Figure 3 As shown, the lifting assembly is provided as a group;

Figure 5 It is a top view schematic diagram showing a ring-shaped product placed on the storage plate 2, and the ring-shaped product can be represented as a sealing ring, etc.;

[0038] (3) Figure 6 As shown, the supporting components are provided in four groups, and the four groups of supporting components are arranged in a circumferential array.

[0039] When product a is of irregular shape, it is difficult to clearly understand the quality of product a by inspecting a single side of product a from a top view. Figure 2 As shown, if the product a in this figure is of an irregular shape, it is difficult to capture the overall appearance of the side of the product a by simply relying on a single position detection under this viewing angle. To this end, a rotating shaft 5 is rotatably provided at the bottom of the frame 1, and the rotating shaft 5 is arranged in the vertical direction. A driving motor 6 is fixedly provided on the frame 1, and the output shaft of the driving motor 6 is in transmission connection with the rotating shaft 5. The storage plate 2 is fixedly installed on the top of the rotating shaft 5. The driving motor 6 can drive the storage plate 2 to rotate, thereby Figure 2 In the state shown, after using the industrial camera 13 to photograph the side of product a, the product a can be driven to rotate a certain angle, and then the industrial camera 13 photographs the side of the product a after the rotation angle again, realizing multi-angle shooting and detection of the side, and accurate detection.

[0040] like Figure 1 As shown, in order to assist the rotation of the storage plate 2, a plurality of rollers 7 can be provided at the bottom of the storage plate 2, and a partition for supporting the plurality of rollers 7 is fixedly provided on the frame 1. Preferably, the storage plate 2 is configured to be circular and is coaxially arranged with the rotating shaft 5.

[0041] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
