Description

Technical Field

[0001] This utility model relates to the field of industrial automation and intelligent inspection, and in particular to a multi-angle visual inspection device that is easy to adjust. Background Technology

[0002] Visual inspection technology, as a core means of industrial automation and intelligent inspection, achieves non-contact measurement and intelligent judgment through machine vision systems. This technology converts the target object into a digital signal through an image acquisition device, and combines edge extraction, 3D reconstruction, and AI algorithms to achieve functions such as dimensional measurement, defect identification, and positioning control, with inspection accuracy reaching sub-millimeter levels. Its non-contact, high-precision, and high-efficiency characteristics make it a key supporting technology for intelligent manufacturing.

[0003] Current visual camera angle adjustments are primarily achieved through internal mechanical structure adjustments or external plane rotation. Internal adjustments include moving / rotating the lens, adjusting the focal length, and independently adjusting the pitch angle of the two cameras via a binocular PMP system. External adjustments rely on equipment such as tripods and pan / tilt heads to achieve height adjustment, horizontal position movement, pitch angle adjustment, and horizontal rotation angle control.

[0004] However, the adjustment process mostly relies on manual operation or step-by-step mechanical adjustment, which cannot achieve stepless continuous adjustment, resulting in low adjustment efficiency and unstable accuracy. In complex industrial environments, mechanical structures are prone to cumulative errors, which directly affect measurement accuracy. These defects restrict the in-depth application of visual inspection in precision manufacturing, dynamic monitoring and other scenarios. There is an urgent need for a multi-angle visual inspection device that can achieve stepless adjustment, is fast and stable and can adapt to complex environments. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-angle visual inspection device that is easy to adjust, overcoming the shortcomings of stepless adjustment and stable adjustment.

[0006] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a multi-angle visual inspection device that is easy to adjust, including a mounting base, a connecting rod connected to the bottom of the mounting base, a ball joint connecting the bottom of the connecting rod to a ball head, a visual camera mounted on the lower end of the ball head, a limiting tube slidably connected inside the connecting rod, a lead screw rotatably connected to the connecting rod at its top, a lead screw threadedly connected to the limiting tube at its lower end, a limiting tube pressing against the ball head at its lower end, an adjusting rod rotatably connected to the side of the connecting rod, a bevel gear connected to the top of the lead screw, a bevel gear connected to one end of the adjusting rod passing through the connecting rod, the two bevel gears meshing, and a protective component for protecting the adjusting rod provided on the outside of the connecting rod.

[0007] Furthermore, the protective assembly includes a protective shell, and limit blocks are connected to both the left and right sides of the connecting rod. The protective shell is slidably connected to the limit blocks and the connecting rod in the interlayer. A pressing rod is slidably connected to the limit blocks. A return spring is sleeved on the pressing rod. One end of the return spring is connected to the pressing rod, and the other end is connected to the limit block. The end of the protective shell is provided with an inclined surface that presses against the end of the pressing rod.

[0008] Furthermore, a roller is rotatably connected to the end of the extrusion rod that contacts the protective shell, and the roller rolls and rubs against the protective shell.

[0009] Furthermore, a handle is connected to the side of the protective shell.

[0010] Furthermore, a rubber pad is connected to the bottom of the limiting tube, and the rubber pad is pressed and engaged with the ball head.

[0011] Furthermore, a damping ring is connected to the bottom of the connecting rod, and the damping ring is slidably connected to the ball head.

[0012] The beneficial effects of this utility model are: 1. By connecting the ball head to the ball joint at the bottom of the connecting rod, and with the elastic friction of the damping ring, a stable damping sensation is generated when the ball head rotates, thereby enabling the visual camera to rotate smoothly at multiple angles and achieve the purpose of continuous and smooth angle adjustment.

[0013] 2. Through the threaded engagement between the lead screw and the limiting tube, and the elastic compression of the rubber pad, when the limiting tube moves downward under the drive of the lead screw, the rubber pad applies uniform pressure to the ball head, thereby achieving precise fixation of the visual camera angle and achieving stable adjustment.

[0014] 3. The adjustment rod is driven by the bevel gear at the top of the lead screw, which drives the lead screw to rotate when the adjustment rod rotates. This achieves precise lifting and lowering control of the limit tube, improves adjustment efficiency, and achieves the purpose of fast and accurate adjustment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Example: An easily adjustable multi-angle visual inspection device, see reference. Figures 1 to 3 As shown, the assembly includes a mounting base 1, a connecting rod 2, a ball joint 3, a vision camera 4, a limiting tube 5, a lead screw 6, a bevel gear 7, an adjusting rod 8, and a protective component. The bottom of the mounting base 1 is connected to the connecting rod 2, and the bottom of the connecting rod 2 is ball-jointed to the ball joint 3. The vision camera 4 is mounted on the lower end of the ball joint 3. The limiting tube 5 is slidably connected inside the connecting rod 2. The top of the lead screw 6 is rotatably connected to the connecting rod 2, and the lower end of the lead screw 6 is threadedly connected to the limiting tube 5. The lower end of the limiting tube 5 is press-fitted with the ball joint 3. The side of the connecting rod 2 is rotatably connected to the adjusting rod 8, and the top of the lead screw 6 is connected to the bevel gear 7. One end of the adjusting rod 8 passes through the connecting rod 2 and is connected to the bevel gear 7. The two bevel gears 7 mesh. The adjusting rod 8 is made of aluminum alloy and has an anodized surface. A protective component is provided on the outside of the connecting rod 2 to protect the adjusting rod 8.

[0022] See Figure 1 and Figure 3 As shown, the protective assembly includes a protective shell 9, a limiting block 10, a pressing rod 11, and a return spring 12. The connecting rod 2 is connected to the limiting blocks 10 on both the left and right sides. The protective shell 9 is slidably connected in the interlayer between the limiting blocks 10 and the connecting rod 2. The protective shell 9 is made of engineering plastic ABS material. The limiting block 10 is slidably connected to the pressing rod 11. The pressing rod 11 is fitted with a return spring 12. One end of the return spring 12 is connected to the pressing rod 11, and the other end is connected to the limiting block 10. The end of the protective shell 9 is provided with an inclined surface that presses against the end of the pressing rod 11.

[0023] See Figure 3As shown, it also includes a roller 13. The end of the extrusion rod 11 that contacts the protective shell 9 is rotatably connected to the roller 13. The roller 13 rolls and rubs against the protective shell 9. The roller 13 is made of nylon material.

[0024] See Figure 3 As shown, it also includes a handle 14. The protective shell 9 has a handle 14 connected to its side. The handle 14 is designed with soft rubber covering. The soft rubber material improves the grip comfort, and the anti-slip texture design ensures that it is not easy to slip out of the hand during operation, thus improving the safety of the adjustment process.

[0025] See Figure 2 As shown, it also includes a rubber pad 15. The bottom of the limiting tube 5 is connected to the rubber pad 15. The rubber pad 15 is squeezed and fitted with the ball head 3. The rubber pad 15 is made of silicone rubber. Silicone rubber has excellent elasticity and aging resistance, and generates uniform contact pressure when squeezed.

[0026] See Figure 2 As shown, it also includes a damping ring 16. The bottom of the connecting rod 2 is connected to the damping ring 16, which is slidably connected to the ball head 3. The elastic deformation of the damping ring 16 can absorb the rotational impact and achieve a smooth transition of angle adjustment.

[0027] When adjusting the angle of the vision camera 4, the operator first rotates the vision camera 4 by hand. The vision camera 4 rotates through the ball joint structure at the bottom of the connecting rod 2 via the ball head 3 at its bottom. As the ball head 3 rotates, its outer surface rubs against the damping ring 16 at the bottom of the connecting rod 2. The elastic material of the damping ring 16 provides appropriate resistance, making the rotation process smooth and damped, facilitating precise control of the rotation angle. After adjusting the angle of the vision camera 4, the adjusting rod 8 is rotated. The adjusting rod 8, through the bevel gear 7 at its end, meshes with the bevel gear 7 at the top of the lead screw 6, driving the lead screw 6 to rotate within the connecting rod 2. The rotation of the lead screw 6 drives the limiting tube 5 downward through the thread, causing the rubber pad 15 at the bottom of the limiting tube 5 to move downward as well, gradually pressing the upper surface of the ball head 3. After being pressed, the rubber pad 15 undergoes local elastic deformation, thereby increasing the contact pressure with the ball head 3, limiting the ball head 3 from continuing to rotate, and stabilizing the adjusted angle of the vision camera 4. Then, grasp the handle 14 of the protective shell 9 and pull the protective shell 9 outward along the limiting block 10. During the sliding process of the protective shell 9, the inclined surface at its end contacts the roller 13 at the end of the extrusion rod 11. The sliding resistance is reduced by rolling friction. Finally, the protective shell 9 frames the adjusting rod 8 to prevent the staff from accidentally touching the adjusting rod 8 in subsequent testing work.

[0028] When the position of the vision camera 4 needs to be adjusted, the protective housing 9 is pushed towards the limiting block 10 by hand. The inclined surface of the protective housing 9 contacts the roller 13 at the end of the pressing rod 11. Due to the rolling characteristics of the roller 13, the pressing rod 11 slides to both sides during the pushing process, while stretching the return spring 12. When the protective housing 9 slides to a certain position, the end of the pressing rod 11 disengages from the inclined surface of the protective housing 9. At this time, the protective housing 9 no longer frames the adjusting rod 8, releasing the protection of the adjusting rod 8. Then, the adjusting rod 8 is rotated. The adjusting rod 8 drives the lead screw 6 to rotate in the opposite direction through the bevel gear 7. The lead screw 6 drives the limiting tube 5 to move upward. The rubber pad 15 at the bottom of the limiting tube 5 rises accordingly and gradually separates from the ball head 3. After the rubber pad 15 is separated, the ball head 3 is no longer under pressure, but due to the elastic holding effect of the damping ring 16, the ball head 3 will not rotate immediately and will maintain its current position. At this time, the operator can slowly rotate the vision camera 4 to adjust its angle to the required position. After adjustment, repeat the above fixing steps: rotate the adjusting rod 8 to move the limiting tube 5 down, the rubber pad 15 squeezes the ball head 3 to fix the angle, and finally pull out the protective shell 9 to protect the adjusting rod 8, thus completing the entire adjustment process.
