Technical Field
[0001] This utility model relates to the field of parts inspection technology, specifically a visual inspection device for springs. Background Technology
[0002] Springs, as a common mechanical part, play a key role in various equipment and mechanical systems. They mainly achieve functions such as buffering, shock absorption, energy storage, and reset through their own elastic deformation. They are widely used in many fields such as automobiles, electronics, home appliances, and construction machinery, and are important components to ensure the normal operation of related equipment.
[0003] During the manufacturing process, springs need to undergo various quality inspections to ensure that their performance meets the requirements for use. In the existing inspection process, springs are transported into the inspection system by a conveyor belt and then inspected by an inspection camera.
[0004] However, existing testing devices cannot accurately assess the performance of springs under specific stress conditions such as tension during the testing process. Therefore, we propose a spring visual inspection device. Utility Model Content

The installation component includes a detection plate, which is fixedly connected to the rear side inside the mounting frame. Two hooks are disposed on the front side of the detection plate, one hook being fixedly connected to the front side of the detection plate and the other hook being slidably connected to the front side of the detection plate. A connecting plate is fixedly connected to the side of the other hook near the detection plate. An installation rod is fixedly connected to the top of the connecting plate on the side away from the detection plate. A motor is fixedly connected to the rear side of the mounting frame, and the motor drive end penetrates through the mounting frame. A cam is fixedly connected to the motor drive end, and the cam is disposed on the top of the installation rod.
[0007] Preferably, the detection component includes a guide rod, which is fixedly connected inside the mounting frame. A fixed frame is slidably connected to the outer periphery of the guide rod. Two bevel gears are rotatably connected inside the fixed frame and mesh with each other. A rotating shaft is fixedly connected to the side of one of the bevel gears away from the guide rod. A camera is fixedly connected to the surface of the rotating shaft. An electric push rod is fixedly connected to the top side of the mounting frame, and the telescopic end of the electric push rod is rotatably connected to the surface of the rotating shaft.
[0008] Preferably, a roller is rotatably connected to the inner side of the top of the mounting rod, and the roller is rotatably connected to the cam surface.
[0009] Preferably, two limiting plates are fixedly connected to the surface of the connecting plate, and the detection plate is disposed on one side of the two limiting plates facing each other.
[0010] Preferably, a connecting ring is fixedly connected to the bottom end of another bevel gear, the connecting ring is slidably connected to the surface of the guide rod, a slider is fixedly connected inside the connecting ring, a groove is opened inside the guide rod, and the slider is slidably connected inside the groove.
[0011] Preferably, a limiting rod is fixedly connected between the upper and lower ends of the inner side of the mounting frame, and the end of the rotating shaft away from the guide rod is slidably connected to the surface of the limiting rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by driving the cam to rotate by the motor, the movable hook moves repeatedly, thereby adjusting the moving distance between the two hooks, and realizing the control of different stretching degrees of the spring.

The detection plate 2 provides a background for spring inspection, facilitating spring detection. Two hooks 8 are located on the front of the detection plate 2. One hook 8 is fixedly connected to the front of the detection plate 2, and the other hook 8 is slidably connected to the front of the detection plate 2. The two ends of the spring can be hung on the two hooks 8 respectively to fix the spring. A connecting plate 9 is fixedly connected to the side of the other hook 8 closest to the detection plate 2. The connecting plate 9 slides inside the detection plate 2, connecting the other hook 8 to the detection plate 2 and driving the other hook 8 to move. An installation rod 11 is fixedly connected to the top of the connecting plate 9 furthest from the detection plate 2. A motor 7 is fixedly connected to the rear of the mounting frame 1. The driving end of the motor 7 passes through the mounting frame 1 and drives a cam 13 to rotate. The driving end of the motor 7 is fixedly connected to the cam 13, which is located on the top of the installation rod 11. During rotation, the cam 13 can push the connecting plate 9 to move via the installation rod 11.
[0021] Please refer to Figure 1 , Figure 4 A detection component is provided on the front side inside the mounting frame 1. The detection component includes a guide rod 3, which is fixedly connected inside the mounting frame 1. The guide rod 3 allows the rotating shaft 14 to move stably. A fixed frame 15 is slidably connected to the outer periphery of the guide rod 3. The fixed frame 15 is used to install two bevel gears 17. The fixed frame 15 is rotatably connected to two bevel gears 17. The two bevel gears 17 are meshed and can drive the camera 5 to rotate through the rotating shaft 14, thereby adjusting the detection angle of the camera 5 to detect different angles of the spring. The rotating shaft 14 is fixedly connected to one of the bevel gears 17 away from the guide rod 3. The camera 5 is fixedly connected to the surface of the rotating shaft 14. The rotating shaft 14 can drive the camera 5 to rotate. An electric push rod 6 is fixedly connected to the top side of the mounting frame 1. The telescopic end of the electric push rod 6 is rotatably connected to the surface of the rotating shaft 14. The telescopic end of the electric push rod 6 can extend and retract, thereby driving the camera 5 to rise and fall.
[0022] Please refer to Figure 3A roller 12 is rotatably connected to the inner side of the top of the mounting rod 11. The roller 12 is rotatably connected to the surface of the cam 13. The roller 12 can rotate to reduce the friction between the mounting rod 11 and the roller 12.
[0023] Please refer to Figure 3 Two limiting plates 10 are fixedly connected to the surface of the connecting plate 9. The detection plate 2 is set on the opposite side of the two limiting plates 10. Installing the limiting plates 10 can restrict the movement of the connecting plate 9.
[0024] Please refer to Figure 5 Another bevel gear 17 is fixedly connected to a connecting ring 16 at its bottom end. The connecting ring 16 is slidably connected to the surface of the guide rod 3. A slider 18 is fixedly connected inside the connecting ring 16. A groove is opened inside the guide rod 3. The slider 18 is slidably connected inside the groove. The groove is a spiral groove. The slider 18 can drive the other bevel gear 17 to rotate by sliding inside the groove through the connecting ring 16.
[0025] Please refer to Figure 1 A limiting rod 4 is fixedly connected between the upper and lower ends of the inner side of the mounting frame 1. The end of the rotating shaft 14 away from the guide rod 3 is slidably connected to the surface of the limiting rod 4. The end of the rotating shaft 14 away from the guide rod 3 is rotatably connected to a connecting sleeve. The connecting sleeve slides on the surface of the limiting rod 4, which allows the rotating shaft 14 to move smoothly along the limiting rod 4.
[0026] Working principle: When using this device to test a spring, the movable hook 8 is pulled towards the fixed hook 8 to minimize the distance between the two hooks 8. Then, the two ends of the spring can be hung on the two hooks 8 respectively to fix the spring. Then, the motor 7 is started. The drive end of the motor 7 drives the cam 13 to rotate. During the rotation of the cam 13, it contacts the roller 12 and pushes the mounting rod 11 and the connecting plate 9 to move, thereby driving the movable hook 8 to move back and forth. During the movement of the movable hook 8, it cooperates with the fixed hook 8 to stretch the spring. This allows the spring to be stretched during the test, so that it can be tested under different stretching conditions, making the test results more accurate.
[0027] When inspecting a spring, camera 5 is activated first. Camera 5 can then accurately capture and collect data on the area the spring is currently facing, completing the initial orientation inspection. When the inspection requires adjustments to the inspection angle for other orientations of the spring, the electric push rod 6 is activated. The telescopic end of the electric push rod 6 extends and retracts, driving the rotating shaft 14 to move along the guide rod 3. As the rotating shaft 14 moves along the guide rod 3, the slider 18 slides within the groove, causing the connecting ring 16 to generate rotational driving force with the displacement of the slider 18. This, in turn, drives two meshing bevel gears 17 to rotate, thereby causing the bevel gears 17 to rotate the rotating shaft 14 and camera 5 to achieve flexible adjustment of the tilt angle. The camera can be raised to increase the top-down view or tilted downwards to increase the bottom-up view, thus achieving full coverage inspection of the spring from multiple orientations, including the top, bottom, sides, and oblique angles, meeting various inspection needs.
