[0002] In modern industrial production, product quality control is a crucial link. In order to ensure the quality of products, visual inspection systems are usually used to inspect products to identify possible defects on the products. Traditional visual inspection systems are usually single-station operations, that is, only one product can be inspected at a time. This inspection method is inefficient and cannot meet the needs of large-scale production.

[0003] With the development of automation technology, multi-station rotary inspection mechanisms have emerged. This inspection mechanism can inspect multiple products at the same time, significantly improving the inspection efficiency. However, the existing multi-station inspection equipment has certain limitations in structural design. For example, the unreasonable layout of motors and pneumatic components may cause position interference, thus affecting the operating efficiency and maintenance cost of the inspection mechanism.

[0004] Therefore, it is necessary to design a multi-station rotation detection mechanism to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a multi-station rotation detection mechanism with high detection efficiency and simple structure.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-station rotary detection mechanism, which includes a turntable, a motor that drives the turntable to rotate, a plurality of suction cup assemblies arranged on the turntable, an air path assembly and a visual detection assembly, the plurality of suction cup assemblies are evenly distributed on the circumference of the turntable, the air path assembly includes a first air pipe corresponding to the suction cup assembly one by one, a second air pipe corresponding to the first air pipe one by one, and a multi-channel rotary joint connecting the first air pipe with the second air pipe, the motor and the air path assembly are respectively arranged on the upper and lower sides of the turntable, and the visual detection assembly is used to perform visual inspection on the products adsorbed by the suction cup assembly.

[0007] As a further improved technical solution of the utility model, the rotary joint includes a rotating part connected to the first air pipe and a fixed part connected to the second air pipe, the rotating part is coaxial with the fixed part, and the rotating part rotates relative to the fixed part.

[0008] As a further improved technical solution of the utility model, a through hole is opened on the turntable, and the rotating part is connected to the motor through the through hole.

[0010] As a further improved technical solution of the utility model, the suction cup assembly includes a suction cup seat and a suction cup arranged on the suction cup seat, and the suction cup has an air port connected to the first air pipe.

[0011] As a further improved technical solution of the utility model, the suction cup seat also has a rib, and the rib is arranged around the outer periphery of the suction cup.

[0012] As a further improved technical solution of the utility model, the turntable is provided with a mounting groove matching the shape of the suction cup seat, and the suction cup passes through the suction cup seat and the mounting groove.

[0013] As a further improved technical solution of the utility model, the turntable is further provided with a plurality of openings for the first air pipe to pass through.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to Figure 1 As shown, the utility model provides a multi-station rotation detection mechanism, which includes a turntable 10, a motor 30 driving the turntable 10 to rotate, a plurality of suction cup assemblies 20 arranged on the turntable 10, an air circuit assembly 40 and a visual detection assembly.

[0023] Multiple suction cup assemblies 20 are evenly distributed on the circumference of the turntable 10. Figure 3 As shown, the suction cup assembly 20 includes a suction cup seat 21, a suction cup 22 and a retaining edge 23. The suction cup 22 is arranged on the suction cup seat 21, and a mounting groove (not numbered) matching the shape of the suction cup seat 21 is arranged on the turntable 10, and a through hole is arranged at the bottom of the mounting groove. When the suction cup assembly 20 is accommodated in the mounting groove, the suction cup 22 passes through the suction cup seat 21 and the through hole of the mounting groove, and the air port of the suction cup 22 is connected to the air path assembly 40 through the through hole.

[0024] The retaining edge 23 is arranged on the upper surface edge of the suction cup seat, and the retaining edge is arranged around the outer periphery of the suction cup 22 and is higher than the suction cup 22. In this way, when the suction cup absorbs the product, the product is surrounded by the retaining edge to prevent the product from colliding with other structures when the turntable rotates. In this embodiment, the suction cup seat 21 is square and is suitable for square products. In other embodiments, suction cup seats of different shapes can also be selected according to the shape of the actual detected product.

[0025] In addition, in other embodiments, the suction cup assembly may also be designed in other forms according to the actual requirements of the product to be inspected, which is not limited here.

[0026] Please refer to Figure 1 and Figure 2As shown, in this embodiment, the motor 30 is arranged below the turntable 10, and the air circuit assembly 40 is arranged above the turntable 10. Specifically, the air circuit assembly 40 includes a plurality of first air pipes 41, a plurality of second air pipes 42, a multi-channel rotary joint 43, a plurality of solenoid valves 44 and a mounting bracket 45. Among them, the suction cup assembly 20, the first air pipe 41, the second air pipe 42 and the solenoid valve 44 correspond to each other and are connected in sequence. Specifically, the first air pipe 41 is connected to the air port of the suction cup 22. The rotary joint 43 is used to connect the first air pipe 41 with the second air pipe 42 in a one-to-one correspondence. The rotary joint 43 includes a rotating part 431 connected to the first air pipe 41 and a fixed part 432 connected to the second air pipe 42. The rotating part 431 is coaxially arranged with the fixed part 432, and the rotating part 431 rotates relative to the fixed part 432. A through hole 12 is opened on the turntable 10, and the rotating part 431 is connected to the motor 30 through the through hole 12 and rotates synchronously with the turntable 10 under the drive of the motor 30. In other embodiments, the rotating part can also be directly fixed to the center of the turntable 10 and rotated driven by the turntable 10. The mounting frame 45 includes a mounting rod disposed above the rotating joint 43 and a mounting platform disposed on the mounting rod, and a plurality of solenoid valves 44 are disposed on the mounting platform and arranged in a circumference.

[0027] In this embodiment, the suction cup 22 of the suction cup assembly 20 faces upwards of the turntable 10 , and the air outlet of the suction cup 22 faces downwards, so the turntable 10 is further provided with a plurality of openings 11 for the first air pipe 41 to pass through.

[0028] The visual inspection component is used to perform visual inspection on the product adsorbed by the suction cup component 20. Preferably, the visual inspection component is one or more of an area array inspection component or a line array inspection component. The visual inspection component is located on the periphery of the turntable 10, and the turntable 10 drives the product to pass through the inspection station of the visual inspection component in sequence. Figure 4 As shown, in this embodiment, the visual inspection component includes two linear array inspection components 50, and the linear array inspection component 50 includes a bracket 51, a mobile module 52 arranged on the bracket 51, a linear array camera 53 and a linear light source 54. The scanning directions of the two linear array inspection components 50 are the same, and the lines connecting the inspection stations of the two linear array inspection components 50 and the rotation center of the turntable are perpendicular to each other. When the product is located at the inspection station of one of the linear array inspection components 50, the linear array inspection component 50 scans the product in the first direction; when the product rotates to the inspection station of the other linear array inspection component, the product rotates 90° in the horizontal direction driven by the turntable. Therefore, although the scanning direction of the other linear array inspection component 50 for the product is the same as that of the first linear array inspection component, for the product, the two scanning directions are perpendicular to each other. With such a setting, more details of the product surface can be captured from different perspectives, and the detection blind spots that may exist in a single direction can be prevented, thereby improving the integrity and accuracy of the detection.

[0029] To summarize, the multi-station rotary inspection mechanism of the present invention arranges a plurality of suction cup assemblies for adsorbing products, thereby driving the products to pass through the inspection stations of the visual inspection assembly in sequence for inspection. It can not only inspect multiple products at the same time to improve the inspection efficiency, but also can arrange different types of visual inspection assemblies to realize the detection of multiple defects, making the inspection more comprehensive. In addition, by placing the motor and pneumatic components on both sides of the turntable respectively, the position interference caused by the two being concentrated on one side is prevented, thereby greatly simplifying the structure of the multi-station rotary inspection mechanism and facilitating the assembly and maintenance of the equipment.
