The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0027] It should be noted that the diagrams provided in this embodiment only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components during actual implementation. The type, quantity, and ratio of each component during actual implementation can be an arbitrary change, and the component layout type may also be more complex.

[0028] Please refer to Figures 1 to 4As shown, the present utility model proposes an auxiliary device for appearance inspection, which is used to inspect the appearance of products produced during the production process of products such as O-rings, special-shaped sealing rings, and oil seals. In the prior art, generally, an optical microscope with a fixed camera is used to inspect the appearance of products, resulting in unclear observation of some surfaces of the products. It is often necessary to manually straighten and twist the products to achieve multi-angle observation, but this method is likely to cause problems such as deformation and tearing of the products. Therefore, an auxiliary device for appearance inspection proposed in this application is used to achieve multi-angle observation and detection of the product appearance to solve the above problems. Specifically, the appearance inspection auxiliary device 100 includes a base 10, a connecting member 20, a fixed disk 30, a rotating disk 40, and a camera 50. The connecting member 20 is rotatably connected to the base 10. The fixed disk 30 is fixedly connected to the connecting member 20. The rotating disk 40 is rotatably mounted on the fixed disk 30. The camera 50 is located above the rotating disk 40 and points to the surface of the rotating disk 40. Under the combined action of the connecting member 20 and the rotating disk 40, the product placed on the rotating disk 40 can be tilted within a certain range and can rotate, so that the camera 50 can photograph the product at different angles to achieve multi-angle detection.

[0029] Please refer to Figure 1 and Figure 3 As shown, in this embodiment, the connecting member 20 is a ball joint structure with damping, which is fixed to the base 10 through a fastening bolt. Through this ball joint structure, it can rotate in different directions, and the maximum angle of rotation of the connecting member 20 is at an angle of 45° with the vertical direction. That is, in any vertical plane passing through the central axis of the connecting member 20, the connecting member 20 can rotate away from the central axis by a maximum angle of 45°, so that the product on the rotating disk 40 can be within a range of 90°. At the same time, this ball joint structure has damping, so that after rotating to a certain angle, it is fixed at the current angle under the action of the damping, so that the product can be fixed at different angles with the camera 50, thus facilitating the camera 50 to take pictures and detect the appearance.

[0030] Please refer to Figure 1 and Figure 3As shown, in this embodiment, the rotating disk 40 is rotatably connected to the fixed disk 30. Specifically, the rotating disk 40 rotates 360° in the plane where the fixed disk 30 is located with the connecting member 20 as the rotation center. Specifically, a mating structure is provided on the surface where the fixed disk 30 and the rotating disk 40 are in contact with each other. The mating structure includes a convex structure and a concave structure. The convex structure is installed in the concave structure. When the rotating disk 40 rotates, the convex structure rotates in the concave structure, that is, the rotating disk 40 rotates 360° in the plane where the fixed disk 30 is located under the cooperation of the convex structure and the concave structure. In this embodiment, the convex structure is provided on the fixed disk 30, and the concave structure is provided on the rotating disk 40. This convex structure can serve as a rotating shaft, and the concave structure serves as a shaft hole that mates with the rotating shaft, enabling the rotating disk 40 to achieve 360° rotation. Combined with the rotation of the connecting member 20, the camera 50 can take photos of different angles and different parts of the product to be inspected, thereby detecting the appearance. It can be understood that in some other embodiments, the convex structure can be provided on the rotating disk 40, and correspondingly, the concave structure is provided on the fixed disk 30.

[0031] Please refer to Figure 2 and Figure 4 As shown, in this embodiment, a limiting structure is further included. The limiting structure is connected between the fixed disk 30 and the rotating disk 40 to limit the axial displacement and radial displacement between the fixed disk 30 and the rotating disk 40, and prevent other displacements of the rotating disk 30 on the fixed disk 30 except rotation, and even prevent it from falling off the fixed disk 30, which may affect the photographing and inspection of the product by the camera. For example, in this embodiment, one end of the convex structure can be provided with a radially protruding convex block, similar to an I-shaped structure. Correspondingly, a radially concave groove is provided on the inner wall of the concave structure. When the rotating disk 40 is connected to the fixed disk 30 in a mating manner, the convex block is located in the groove to achieve limiting.

[0032] Of course, in some other embodiments, the surface of the fixed disk 30 facing the rotating disk 40 can be integrally arranged as a concave structure, and grooves recessed radially are arranged on the inner walls around the fixed disk 30. Correspondingly, grooves recessed radially are arranged around the rotating disk 40, and the convex blocks are engaged with the grooves to achieve limiting. At the same time, the cooperation between the grooves and the convex blocks can also realize the rotational connection between the rotating disk 40 and the fixed disk 30. Of course, the surface of the rotating disk 40 facing the fixed disk 30 can also be integrally arranged as a concave structure, and grooves recessed radially are arranged on the inner walls around the rotating disk 40. Correspondingly, grooves recessed radially are arranged around the fixed disk 30, and the convex blocks are engaged with the grooves to achieve limiting. At the same time, the cooperation between the grooves and the convex blocks can also realize the rotational connection between the rotating disk 40 and the fixed disk 30.

[0033] Please refer to Figure 2 and Figure 4 As shown, in this embodiment, the appearance inspection auxiliary device further includes a locking structure, which is arranged on the fixed disk 30 and is used to connect with the rotating disk 40 to lock the rotating disk 40. For example, the locking structure is a fixing bolt 401, and the fixing bolt 401 is threadedly connected with the fixed disk 30. When the fixing bolt 401 is tightened, one end of the fixing bolt 401 tightly abuts against the rotating disk 40 to limit the rotation of the rotating disk 40 and fix the rotating disk 40 at a certain position, so that the product to be inspected is in different directions, and the photographing inspection of different parts of the product to be inspected is realized by the rotation of the connecting member 20. In this embodiment, a rotating handle 402 is further arranged on the outer circumference of the rotating disk 40, and the rotating disk 40 can be conveniently rotated through the rotating handle 402, so as to change the direction of the product to be inspected.

[0034] Please refer to Figure 2 and Figure 4As shown, in this embodiment, a groove is provided on the side of the rotating disk 40 away from the fixed disk 30. The groove is used to place the product to be inspected. The design of the groove can prevent the product to be inspected from detaching from the rotating disk 40 when the rotating disk 40 is tilted. In some other embodiments, an auxiliary fixing member can also be provided. The auxiliary fixing member is placed in the groove, and a groove structure adapted to the shape of the product to be inspected is provided on the auxiliary fixing member, so as to better limit the product to be inspected and be able to replace the adapted auxiliary fixing member according to the actual product to be inspected. In some other embodiments, an anti-slip pad can also be provided on the side of the rotating disk 40 away from the fixed disk 30. The product to be inspected is placed on the anti-slip pad to prevent the product to be inspected from sliding on the rotating disk 40 when the rotating disk is tilted. Of course, it can be understood that a groove and an anti-slip pad can also be provided on the side of the rotating disk 40 away from the fixed disk 30 at the same time. The anti-slip pad is located at the bottom of the groove, or other limiting structures can also be provided to limit the relative displacement of the product to be inspected on the rotating disk 40.

[0035] The present utility model provides an appearance inspection auxiliary device. The appearance inspection auxiliary tooling includes a base, a ball head rotary joint, a fixed disk and a rotating disk. The lower end of the ball head rotary joint is fixed on the base, and the upper end is connected to the fixed disk. The rotating disk is placed on the fixed disk, and the product to be inspected is placed on the rotating disk. Under the action of the ball head rotary joint, the product on the rotating disk can rotate at any angle within a range of 90°, so that the fixed camera can observe the side of the product. With the cooperation of the rotating disk that rotates 360°, the fixed camera can maintain the same angle to observe different positions of the product without moving the product.
