Technical Field

[0001] The utility model relates to the field of optical automation detection, in particular to a ring-shaped line visual detection mechanism. Background Art

[0002] With the rapid development of industrial automation technology, machine vision systems are playing an increasingly important role in product quality control. Traditional visual inspection systems typically use linear or fixed inspection methods, where the product under inspection moves or remains stationary on a linear track. However, this traditional layout has limitations, such as low inspection efficiency, large footprint, and the inability to achieve continuous in-line inspection.

[0003] To address these issues, the industry has begun exploring more efficient and compact visual inspection solutions. The circular linear visual inspection mechanism, an innovative design, combines a drive assembly, a circular guide rail, a support fixture, and a vision component to achieve a novel automated visual inspection method. In this design, multiple support fixtures are driven by the drive assembly and move along the circular guide rail. This allows products to be continuously transported to different inspection stations, where they are inspected by the vision component during movement.

[0004] While existing circular line visual inspection mechanisms have improved inspection efficiency and accuracy to a certain extent, they still have some shortcomings. For example, the support fixture is unstable during movement and produces a lot of noise, which reduces the accuracy of visual inspection results. In addition, the existing technology lacks a mechanism to flip the product on the support fixture, resulting in a significant gap between inspection efficiency and expectations.

[0005] Therefore, it is necessary to design a circular line visual detection mechanism to solve the above problems. Utility Model Content

[0009] As a further improved technical solution of the present invention, the carrying fixture includes a support plate and a limiting portion provided on the support plate, and the limiting portion is used to position the product to be tested.

[0010] As a further improved technical solution of the present invention, the annular guide rail is arranged on the outer periphery of the belt, and a slider that slides in cooperation with the annular guide rail is provided under the support plate.

[0029] An annular guide rail 20 is disposed on the outer periphery of the belt 13, and a support fixture 30 is slidably mounted on the annular guide rail 20. The support fixture 30 includes a support plate 31, a limiting portion 32 disposed on the support plate 31, and a mounting block 33. The support plate 31 is the main body of the support fixture 30 and is plate-shaped. A notch 311 is defined on one side of the support plate 31, and a limiting portion 32 is disposed within the notch 311. The limiting portion 32 is used to position the product 200 under test. When the product is placed on the support fixture 30, the limiting portion 32 engages with the side and bottom edges of the product.

[0030] The mounting block 33 is located at the bottom of one side of the support plate 31 and partially protrudes from the support plate 31. A fixing groove 331 is defined on the side of the mounting block 33 facing the belt 13. The belt 13 is provided with a fixing block 131 that engages with the fixing groove 331. The fixing groove 331 is vertically arranged, and the fixing block 131 is vertically engaged with the fixing groove 331.

[0031] A slider is provided below the support plate 31, which slides in cooperation with the annular guide rail 20. A locking assembly is also provided below the support plate 31. The locking assembly includes a locking plate 34 and a lifting rod 35. The locking plate 34 is located below the support plate 31 and is fixedly connected to the support plate 31. The locking plate 34 has a slot that cooperates with the lifting rod 35. The lifting rod 35 rises or falls to lock or unlock the locking plate 34.

[0032] The visual component 40 is positioned along the path of the support fixture 30 to perform visual inspection of the product under test on the support fixture 30. In this embodiment, the visual component 40 includes a front appearance inspection component 41, a front dark crack inspection component 42, a back appearance inspection component 43, and a back dark crack inspection component 44, which are sequentially arranged to inspect the front appearance, front dark cracks, back appearance, and back dark cracks of the product, respectively. In other embodiments, the type and quantity of visual components can be designed according to actual needs to complete the required inspection items.

[0033] The flip assembly 50 is provided between the front crack detection assembly 42 and the back appearance detection assembly 43, and is used to flip the product to be tested on the supporting fixture 30. Figure 3As shown, the flip assembly 50 includes a lifting drive 51, a rotation drive 52 provided on the lifting drive 51, and a suction cup assembly 53 provided on the rotation drive 52.

The first supporting jig 30 is moved between the first and second cantilever arms 531, 532 by a belt. The lifting drive is then activated, causing the upper first cantilever 531 to descend. When the first cantilever 531 descends into position, the suction cup absorbs the first product. The first cantilever 531 then rises and returns to its original position. The second supporting jig 30 is then moved between the first and second cantilever arms 531, 532 by a belt. The lifting drive is then activated, causing the lower second cantilever 532 to ascend. When the second cantilever 532 ascends into position, the suction cup absorbs the second product. The suction cup assembly 53 then continues to rise a distance to allow sufficient rotational space for the entire suction cup assembly 53. The rotation drive is then activated, causing the entire suction cup assembly 53 to rotate 180 degrees, with the second cantilever 532 at the top and the first cantilever 531 at the bottom. Next, the first support jig 30 is driven back to below the first cantilever 531. The first cantilever 531 further descends and places the first product on the first support jig 30, which is then removed. The suction cup assembly height is adjusted so that the second support jig 30 moves between the first and second cantilever arms 531, 532. The second cantilever 532 then descends and places the second product on the second support jig. In this manner, the two products are flipped over by rotating sequentially. During the lifting and lowering process, the first and second cantilever arms 531, 532 can pass through the notch 311 on the support plate 31.
