Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment, and more specifically, to a multi-angle visual inspection device. Background Technology

[0002] In the manufacturing process of precision electronic products, visual inspection of various surfaces is required to ensure product quality. Some products need to be placed in specific transfer fixtures on the production line to ensure positioning and transmission stability. However, the positioning structure required by these fixtures often obstructs critical surfaces to be inspected, making it impossible to obtain complete images.

[0003] While existing automated visual inspection equipment can achieve multi-angle imaging, most lack efficient product handling and posture coordination control capabilities. Some inspection agencies rely on complex rotating mechanisms to drive the entire vehicle movement, which cannot solve the occlusion problem caused by the fixture itself. Furthermore, existing inspection agencies need to be configured with multiple independent workstations and camera groups to inspect different surfaces, resulting in large equipment size and long cycle time. Utility Model Content

[0004] The purpose of this invention is to provide a multi-angle visual inspection device that is compact in structure, highly efficient in operation, and capable of automated visual inspection of the entire circumference of a product, thereby improving inspection efficiency and reliability.

[0005] A multi-angle visual inspection device, comprising: A clamping and flipping mechanism is used to clamp and flip the product to be inspected; A drive mechanism, connected to the clamping and flipping mechanism, is used to drive the clamping and flipping mechanism to move horizontally and vertically; and A visual inspection mechanism includes a rotating stage and two side inspection components disposed opposite each other on both sides of the rotating stage. The rotating stage is used to carry a product and is configured to rotate about a vertical axis to perform visual inspection of the circumferential surface of the product by means of the two side inspection components.

[0006] In the above technical solution, by integrating a clamping and flipping mechanism, a driving mechanism, and a vision inspection mechanism, automated multi-angle inspection of the product to be inspected is achieved. The clamping and flipping mechanism is responsible for grasping the product from the external transfer mechanism and changing its orientation. The driving mechanism enables the clamping and flipping mechanism to move flexibly in the horizontal and vertical directions to accurately pick up and place the product. The rotating stage in the vision inspection mechanism carries the product, and its rotation function, together with the side inspection components fixed on both sides, allows for visual scanning of the entire circumference of the product without secondary product movement. The overall structure is compact and efficient, significantly improving the inspection coverage and the degree of automation.

[0007] Furthermore, the rotating platform includes a rotating drive and a support base. The output end of the rotating drive is connected to the support base, and the rotating drive is used to drive the support base to rotate.

[0008] In the above technical solution, the output end of the rotary drive is directly connected to the bottom of the carrier. This structure ensures that the rotary drive can directly drive the carrier to rotate, thus improving the stability and reliability of the detection.

[0009] Furthermore, the support seat is provided with a positioning groove that matches the contour of the product.

[0010] In the above technical solution, the support is provided with a positioning groove that matches the product contour, which can effectively constrain the position of the product during the testing process, prevent it from shaking or shifting, and ensure testing accuracy.

[0011] Furthermore, the side detection component includes a translation drive component, a movable seat, and a camera. The translation drive component is connected to the movable seat and is used to drive the movable seat to move closer to or away from the rotating platform. The camera is mounted on the movable seat.

[0012] In the above technical solution, the side detection component adopts a structure in which the movable seat is moved by the translation drive component, which enables the camera to flexibly adjust the distance between itself and the rotating stage according to the product size or detection requirements, thereby enhancing the equipment's adaptability to products of different specifications and its detection flexibility.

[0013] Furthermore, the movable seat is equipped with a light source, which is located between the camera and the rotating platform, and the light source has a through hole for the camera to take pictures.

[0014] In the above technical solution, a light source is placed on the movable base between the camera and the rotating stage, and is equipped with a through-hole structure. This allows the light source to directly and evenly illuminate the side of the product, providing sufficient and stable lighting conditions for the camera and significantly improving the imaging effect. The through-hole on the light source ensures that the optical path of the camera is unobstructed, effectively preventing the light source itself from obstructing the camera's field of view.

[0015] Furthermore, the clamping and flipping mechanism includes a gripper and a clamping drive, the clamping drive being used to drive the gripper to clamp and flip.

[0016] In the above technical solution, the clamping drive can directly control the gripper to perform clamping action to firmly grasp the product and drive it to complete the required flipping action to change the product orientation. This integrated drive design simplifies the actuator, so that the two key actions of clamping and flipping can be reliably and efficiently completed by the same set of mechanisms. The structure is compact and the action is smooth, which improves the efficiency and reliability of operation.

[0017] Furthermore, one of the grippers has a flexible cushioning pad on its surface facing the other gripper.

[0018] In the above technical solution, a flexible buffer pad is provided on the clamping surface of the gripper. When the gripper performs the clamping action, the buffer pad can effectively absorb the impact force and increase the friction of the contact surface. This not only protects the product surface from scratches or indentations caused by the rigid gripper, but also provides a more stable and gentler clamping force, preventing the product from accidentally slipping or being damaged during clamping or flipping, thus improving the safety of operation and the protection of the product.

[0019] Furthermore, the driving mechanism includes a first driving component and a second driving component. The first driving component is used to drive the clamping and flipping mechanism to move horizontally, and the second driving component is used to drive the clamping and flipping mechanism to move vertically. In the above technical solution, the drive mechanism adopts a division of labor structure in which the first drive component is responsible for horizontal movement and the second drive component is responsible for vertical lifting, which makes the movement control of the clamping and flipping mechanism in space clearer and more precise.

[0020] Compared with existing technologies, the advantages of this invention are: by integrating a clamping and flipping mechanism, a driving mechanism, and a vision inspection mechanism, it achieves automated multi-angle inspection of the product to be inspected. The clamping and flipping mechanism is responsible for grabbing the product from the external transfer mechanism and changing its orientation. The driving mechanism enables the clamping and flipping mechanism to move flexibly in the horizontal and vertical directions to accurately pick up and place the product. The rotating stage in the vision inspection mechanism carries the product, and its rotation function, combined with the side inspection components fixed on both sides, allows for visual scanning of the entire circumference of the product without secondary product movement. The overall structure is compact and efficient, significantly improving the inspection coverage and automation level. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] Please refer to Figures 1 to 4 In a preferred embodiment, the multi-angle visual inspection device of this utility model mainly includes a clamping and flipping mechanism 1, a driving mechanism 2, and a visual inspection mechanism 3. The clamping and flipping mechanism 1 is used to clamp and flip the product to be inspected. The driving mechanism 2 is connected to the clamping and flipping mechanism 1 and is used to drive the clamping and flipping mechanism 1 to move in the horizontal and vertical directions. The visual inspection mechanism 3 includes a rotating platform 31 and two side inspection components 32 disposed opposite to each other on both sides of the rotating platform 31. The rotating platform 31 is used to carry the product and is configured to rotate around a vertical axis to perform visual inspection of the product's circumference through the two side inspection components 32.

[0029] By integrating a clamping and flipping mechanism 1, a drive mechanism 2, and a vision inspection mechanism 3, automated multi-angle inspection of the product to be inspected is achieved. The clamping and flipping mechanism 1 is responsible for grabbing the product from the external transfer mechanism and changing its orientation. The drive mechanism 2 enables the clamping and flipping mechanism 1 to move flexibly in the horizontal and vertical directions to accurately pick up and place the product. The rotating stage 31 in the vision inspection mechanism 3 carries the product, and its rotation function, together with the side inspection components 32 fixed on both sides, allows for visual scanning of the entire circumference of the product without secondary product movement. The overall structure is compact and efficient, significantly improving the inspection coverage and the degree of automation.

[0030] Please refer to Figure 4The rotating stage 31 includes a rotation drive 311 and a support base 312. The output end of the rotation drive 311 is connected to the bottom of the support base 312. For example, the rotation drive 311 can be a motor, with its output end connected to the support base 312. The rotation drive 311 drives the support base 312 to rotate along a vertical axis. By directly connecting the output end of the rotation drive 311 to the bottom of the support base 312, it is ensured that the rotation drive 311 can drive the support base 312 to rotate, thus improving the stability and reliability of the detection.

[0031] In this embodiment, the support 312 is provided with a positioning groove 3121 that matches the contour of the product. The positioning groove 3121 on the support 312 that matches the contour of the product can effectively constrain the position of the product during the inspection process, prevent it from shaking or shifting, and ensure inspection accuracy.

[0032] Please refer to Figure 3 The side detection component 32 includes a translation drive component 321, a movable seat 322, and a camera 323. The translation drive component 321 is connected to the movable seat 322 and is used to drive the movable seat 322 closer to or further away from the rotating stage 31. The camera 323 is mounted on the movable seat 322. For example, the translation drive component 321 can be an existing linear drive module. The side detection component 32 adopts a structure in which the translation drive component 321 drives the movable seat 322 to move, allowing the camera 323 to flexibly adjust its distance from the rotating stage 31 according to the product size or detection requirements, thereby enhancing the adaptability and detection flexibility of the equipment to products of different specifications.

[0033] In this embodiment, a light source 324 is provided on the movable base 322. The light source 324 is located between the camera 323 and the rotating stage 31, and the light source 324 has a through hole for the camera 323 to take pictures. The structure of the light source 324 on the movable base 322 between the camera 323 and the rotating stage 31, with the through hole, allows the light source 324 to directly and evenly illuminate the side of the product, providing sufficient and stable lighting conditions for the camera 323 and significantly improving the imaging effect. The through hole on the light source 324 ensures that the optical path of the camera 323 is unobstructed, effectively preventing the light source 324 itself from obstructing the field of view of the camera 323.

[0034] Please refer to Figure 2The clamping and flipping mechanism 1 includes a gripper 11 and a clamping drive 12. The clamping drive 12 is used to drive the gripper 11 to clamp and flip. The clamping drive 12 can adopt an existing rotary clamping device. The clamping drive 12 can directly control the gripper 11 to perform clamping actions to firmly grasp the product and drive it to complete the required flipping action to change the product orientation. This integrated drive design simplifies the execution mechanism, so that the two key actions of clamping and flipping can be reliably and efficiently completed by the same mechanism. The structure is compact and the action is smooth, which improves the efficiency and reliability of operation.

[0035] In this embodiment, a flexible buffer pad 13 is provided on the surface of one gripper 11 facing the other gripper 11. The flexible buffer pad 13 is provided on the gripping surface of the gripper 11. When the gripper 11 assembly performs a gripping action, the buffer pad can effectively absorb the impact force and increase the friction of the contact surface. This not only protects the product surface from scratches or indentations caused by the rigid gripper 11, but also provides a more stable and gentler gripping force, preventing the product from accidentally slipping or being damaged during gripping or flipping, thus improving the safety of operation and the protection of the product.

[0036] Please refer to this again. Figure 1 The drive mechanism 2 includes a first drive component 21 and a second drive component 22. The first drive component 21 drives the clamping and flipping mechanism 1 to move horizontally, and the second drive component 22 drives the clamping and flipping mechanism 1 to move vertically. Both the first drive component 21 and the second drive component 22 can be existing linear drive modules. The drive mechanism 2's division of labor—first drive component 21 for horizontal movement and second drive component 22 for vertical movement—makes the spatial movement control of the clamping and flipping mechanism 1 clearer and more precise.
