In many manufacturing processes, visual recognition technology is widely used for product inspection, positioning, and quality control. However, existing visual recognition systems have some limitations.

[0003] Traditional visual recognition systems typically offer only fixed or limited angles of view, making them inadequate for complex product inspections. For example, in the electronics manufacturing industry, component soldering on PCBs needs to be inspected from multiple angles. Similarly, in automotive assembly lines, ensuring correct component installation requires different viewing angles. Existing systems often lack the flexibility to adjust the camera's angle to meet these requirements. Utility Model Content

The pen-shaped cylinder drives the second L-support to adjust the inclination, so that the second L-support moves at the end hinged to the first L-support, thereby increasing the range of visual recognition. At the same time, the rotating installation of the first L-support helps to adjust the inclination of the visual recognition CCD camera and the circumferential rotation during visual recognition. In addition, it also has a inclination adjustment buffer component that helps to improve the stability of the visual recognition CCD camera during vertical, inclination adjustment and circumferential rotation.

[0016] The beneficial effects of the present invention are:

[0017] This visual recognition positioning device utilizes an articulated design between the first and second L-shaped supports, along with a tilt adjustment mechanism driven by a pen-shaped cylinder, to enable the visual recognition CCD camera to achieve multi-angle viewing angle adjustment. This includes not only horizontal rotation but also vertical pitch adjustment, enabling the system to adapt to products of varying heights, shapes, and positions. A servo motor drives the first L-shaped support for circumferential rotation, further increasing the visual recognition angular range and ensuring optimal image acquisition.

[0018] Tilt adjustment buffer components (such as buffer air springs and arc-shaped guard plates) provide the necessary buffering effect when the visual recognition CCD camera is adjusted in angle, reducing vibration caused by rapid movement or adjustment, thereby improving the quality and stability of image acquisition.

[0019] The visual recognition CCD camera is capable of simultaneous horizontal rotation, pitch adjustment, and vertical height adjustment. This comprehensive adjustment capability enables the visual recognition system to more flexibly meet the needs of different working environments, and can obtain clear images on both flat and curved surfaces, thereby improving the accuracy and reliability of detection.

[0020] By providing a tilt adjustment buffer component, the stability of the visual recognition CCD camera can be maintained even when performing complex viewing angle adjustments, reducing image blur or distortion caused by mechanical movement and ensuring high-quality image acquisition.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] This embodiment discloses Figures 1 to 6 A visual recognition positioning device shown includes a three-axis moving module 1, the free end of which is provided with a visual recognition mechanism 2. The visual recognition mechanism 2 includes a visual recognition CCD camera 8 for capturing image information of a product to determine the specific position and posture of the product. Automated visual inspection and high-precision position recognition are achieved. The visual recognition mechanism 2 includes a first L-shaped support 9 rotatably mounted on the free end of the three-axis moving module 1 and inverted, a second L-shaped support 13 hinged to the top of the first L-shaped support 9, and a visual recognition CCD camera 8 longitudinally mounted on the outer wall of the second L-shaped support 13 facing away from the first L-shaped support 9. The camera lens barrel 14 of the visual recognition CCD camera 8 faces vertically downward for visual recognition of the product below. The first L-shaped support 9 serves as a mounting base for the visual recognition mechanism 2 and is rotatable, which helps to adjust the angle of the visual recognition CCD camera 8 and increase its flexibility. A pen-shaped oil cylinder 18 is tiltedly mounted on the lower inner wall of the first L-shaped support 9. The free end of the piston rod of the pen-shaped oil cylinder 18 is hinged to the inner wall of the second L-shaped support 13. The piston rod of the pen-shaped oil cylinder 18 pushes and pulls the second L-shaped support 13 to adjust the visual recognition tilt angle of the visual recognition CCD camera 8. A tilt adjustment buffer is provided between the camera lens barrel 14 and the outer wall of the second L-shaped support 13. The pen-shaped oil cylinder 18 drives the second L-shaped support 13 to adjust its tilt angle, allowing the second L-shaped support 13 to move at the end hinged to the first L-shaped support 9, thereby increasing the visual recognition range. The rotatable mounting of the first L-shaped support 9 also facilitates adjusting the tilt angle of the visual recognition CCD camera 8 during circumferential rotation. Furthermore, the tilt adjustment buffer helps improve the stability of the visual recognition CCD camera 8 during vertical, tilt adjustment, and circumferential rotation. The second L-shaped support 13 is connected to the carrier of the visual recognition CCD camera 8 and cooperates with the pen-shaped oil cylinder 18 to adjust the tilt angle. The pen-shaped oil cylinder 18 provides power to adjust the tilt angle of the second L support 13 , thereby adjusting the pitch angle of the visual recognition CCD camera 8 .

[0038] In this embodiment, a servo motor 12 is mounted on the top surface of the first L-shaped support 9. The bottom output shaft of the servo motor 12 extends longitudinally through the first L-shaped support 9 and drives the first L-shaped support 9 in circumferential rotation. A mounting plate 11 is welded to the tail end of the servo motor 12. A shaft hole 20 is defined on the top surface of the first L-shaped support 9 for mounting the output shaft of the servo motor 12. The servo motor 12 drives the first L-shaped support 9 in circumferential rotation, thereby changing the horizontal viewing angle of the visual recognition CCD camera 8.

[0039] In this embodiment, a hinge groove 19 is formed at one end of the first L-shaped support 9 close to the second L-shaped support 13 , and an end of the second L-shaped support 13 close to the first L-shaped support 9 is hinged to the hinge groove 19 via a pin.

[0040] In this embodiment, an inclined mounting seat 21 is welded to the lower portion of the inner wall of the first L-shaped support 9 , and the tail end of the pen-shaped oil cylinder 18 is fixedly mounted on the surface of the inclined mounting seat 21 .

[0041] In this embodiment, two hinged lugs 22 are symmetrically fixed to the free end of the piston rod of the pen-shaped oil cylinder 18. A hinge block 23 is welded to the inner wall of the second L-shaped support 13. The hinge block 23 is positioned between the two hinged lugs 22 and hinged together via a hinge pin 24. The hinged lugs 22, hinge block 23, and hinge pin 24 form an articulated system that allows the second L-shaped support 13 to rotate about a specific axis while maintaining structural integrity.

[0042] In this embodiment, a supporting seat 15 is welded to one end of the second L-shaped support 13 away from the first L-shaped support 9 , and the camera lens barrel 14 passes through longitudinally to the lower outer side of the supporting seat 15 .

[0043] In this embodiment, the tilt adjustment buffer component includes a buffer air spring 16 fixedly mounted transversely to the lower outer wall of the second L-shaped support 13, and a curved guard plate 17 secured to the free end of the buffer air spring 16. The curved guard plate 17 is clipped onto the outer wall of the camera lens barrel 14. This provides shock absorption for the visual recognition CCD camera 8, the camera lens barrel 14, and the second L-shaped support 13. The buffer air spring 16 and curved guard plate 17 form the tilt adjustment buffer component, reducing the impact on the visual recognition CCD camera 8 during adjustment, thereby improving its operational stability and reliability.

[0044] In this embodiment, the pen-shaped oil cylinder 18 is connected to the first L-shaped support 9 via a positioning mechanism 10. This positioning mechanism 10 comprises a positioning collar 25 sleeved around the periphery of the pen-shaped oil cylinder 18 and two positioning links 26 symmetrically welded to the outer walls of the collar 25. The positioning mechanism 10 assists in securing the pen-shaped oil cylinder 18 and, through a locking nut 28 and other structures, ensures its stability, preventing positional displacement due to factors such as vibration.

[0045] In this embodiment, two positioning rods 26 extend through the outside of the first L-shaped support 9 and are threadedly connected to a locking nut 28 at one end via a threaded path 27. The locking nut 28 abuts the outer wall of the first L-shaped support 9. The positioning snap ring 25, positioning rods 26, threaded path 27, and locking nut 28 work together to position the pen-shaped cylinder 18, ensuring that it does not loosen or move unnecessarily during operation.

[0046] In this embodiment, the three-axis motion module 1 comprises four support columns 3 arranged in a rectangular pattern, Y-axis guide rails 4 fixed to the top surfaces of two adjacent support columns 3, an X-axis guide rail 5 slidably connected between the two Y-axis guide rails 4, and a Z-axis guide rail 6 slidably mounted around the periphery of the X-axis guide rail 5. A Z-axis lift slide 7 is slidably connected to the lower portion of the Z-axis guide rail 6, and a mounting plate 11 is bolted to the bottom end of the Z-axis lift slide 7. The three-axis motion module 1 provides precise displacement control in the X, Y, and Z directions, allowing the visual recognition mechanism 2 to reach any position within the working area. This enables multi-angle, all-round inspection and positioning of products.

[0047] In this embodiment, there is a distribution box outside the three-axis mobile module 1, which contains a PLC for opening and closing the three-axis mobile module 1, the pen-shaped cylinder 18 and the servo motor 12. The PLC model can be selected according to actual needs.

[0048] Working principle:

[0049] This visual recognition positioning device uses X-axis guide rails 5, Y-axis guide rails 4, and Z-axis guide rails 6 to move the visual recognition mechanism 2 above or next to the product being inspected. A Z-axis lift slider 7 adjusts the height of the visual recognition CCD camera 8 to the appropriate shooting distance. A servo motor 12 rotates the first L-shaped support 9 to adjust the horizontal viewing angle of the visual recognition CCD camera 8. Simultaneously, a pen-shaped cylinder 18 adjusts the tilt angle of the second L-shaped support 13, thereby finely adjusting the pitch angle of the visual recognition CCD camera 8 to achieve the optimal shooting angle.

[0050] When the visual recognition CCD camera 8 is adjusted to the ideal position, it will start to capture the image of the product to be inspected and identify the product's position, shape, size and other characteristic information.

[0051] During the entire process, the buffer air spring 16 and the arc-shaped guard plate 17 provide the necessary buffering effect, reducing the vibration caused by rapid movement or adjustment, ensuring the quality of image acquisition, and the positioning mechanism 10 ensures the stability of key moving parts such as the pen-shaped cylinder 18, preventing position displacement due to external factors.

[0052] If further fine-tuning of the position is required, the precise positioning process in the position adjustment step is repeated until satisfactory accuracy is achieved. After completing the designated task, the visual recognition mechanism 2 returns to the initial position or a preset safe position.

[0053] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
