[0001] This utility model relates to the field of visual inspection equipment technology, and in particular to an adjustable visual inspection device. Background Technology

[0002] In today's industrial production and quality inspection field, visual inspection devices have become key equipment for ensuring product quality due to their advantages such as high precision, high efficiency and non-contact inspection. As the manufacturing industry develops towards intelligence and refinement, higher requirements are placed on the flexibility and adaptability of visual inspection devices.

[0003] Taking the CN222506132U patent, "An Adjustment Mechanism for a Visual Inspection Device," as an example, this device can achieve a certain degree of adjustment. It uses a first motor to drive a lead screw, which in turn drives related components to rotate the visual detector body, allowing for the inspection of other surfaces of the workpiece. However, its adjustment method is relatively simple, and the camera mounting structure lacks a multi-dimensional, flexible adjustment design. When faced with products of complex shapes and large size differences, it is difficult to quickly and accurately adjust the camera to the optimal inspection position and angle, making it impossible to efficiently acquire comprehensive and clear inspection images. This significantly limits the improvement of inspection efficiency and accuracy, and thus has certain shortcomings. Therefore, we propose an adjustable visual inspection device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3An adjustable visual inspection device includes a base 1, a worktable 2 and a support mechanism 3 mounted on the top of the base 1. The worktable 2 is used to place the workpiece to be inspected. An adjustment mechanism 4 is mounted on the side of the support mechanism 3, and a camera 5 is mounted on the bottom of the adjustment mechanism 4. The support mechanism 3 and the adjustment mechanism 4 are used to adjust the position of the camera 5. The support mechanism 3 includes a fixing frame 30 fixed to the base 1. A first motor 31 is mounted on the side of the fixing frame 30. The output shaft of the first motor 31 is inserted into the interior of the fixing frame 30 and connected to a first threaded post 32. A first slider 33 is threadedly connected to the first threaded post 32. A first movable frame 34 is mounted on the top of the first slider 33. A second motor 35 is installed on the top of the first movable frame 34. The output shaft of the second motor 35 is inserted into the interior of the first movable frame 34 and connected to a second threaded post 36. A second slider 37 is threadedly connected to the second threaded post 36. The first slider 33 is slidably connected to the fixed frame 30, and the second slider 37 is slidably connected to the first movable frame 34. The adjusting mechanism 4 is fixed to the side of the second slider 37. The adjusting mechanism 4 includes a first housing 40 fixed to the side of the second slider 37. A third motor 41 is installed inside the first housing 40. The output shaft of the third motor 41 passes through the side of the first housing 40 and is connected to a movable sleeve 42. A second movable frame 43 is installed on the side of the movable sleeve 42. The second movable frame 43 has an inner... A third threaded post 44 is fixedly mounted on the third threaded post 44. A threaded sleeve 45 is threadedly connected to the third threaded post 44. A first bevel gear 46 is fixedly sleeved on the threaded sleeve 45. A second housing 47 is rotatably connected to the threaded sleeve 45. A fourth motor 48 is mounted on the top of the second housing 47. The fourth motor 48 is inserted into the interior of the second housing 47 and connected to a second bevel gear 49. The second housing 47 and the second movable frame 43 are slidably connected. The first bevel gear 46 and the second bevel gear 49 are meshed and driven. The camera 5 is mounted on the bottom of the second housing 47. In the support mechanism, the first motor drives the first threaded post to rotate, which allows the first slider to slide along the fixed frame to achieve coarse adjustment of the camera. The second motor drives the second... The rotation of the threaded column drives the second slider to move up and down on the first movable frame, adjusting the camera position. The third motor of the adjustment mechanism drives the movable sleeve to rotate, causing the second movable frame to rotate accordingly, thus adjusting the camera's viewing angle. The output shaft of the fourth motor drives the second bevel gear, which meshes with the first bevel gear to drive the threaded sleeve to rotate, thereby causing the second housing to slide within the second movable frame to adjust the camera. This allows for flexible adjustment of the camera's position and angle in multiple dimensions, enabling the camera to be quickly and accurately adjusted to the optimal detection position and angle. When dealing with products with complex shapes and large size differences, this device, with its multi-dimensional flexible adjustment function, can efficiently acquire comprehensive and clear detection images.

[0019] In use, the workpiece is placed on the workbench 2. When the camera 5 needs to be adjusted, the first motor 31 is turned on. The output shaft of the first motor 31 drives the first threaded column 32 to rotate. Since the first slider 33 is threadedly connected to the first threaded column 32 and is slidably connected to the fixed frame 30, the first slider 33 will slide along the inside of the fixed frame 30, thereby driving the first movable frame 34, the second motor 35, and other components to move, achieving coarse adjustment of the position of the camera 5. The second motor 35 is then started, and its output shaft drives the second threaded column 36 to rotate. The second slider 37 is threadedly connected to the second threaded column 36 and slidably connected to the first movable frame 34. The second slider 37 will slide within the first movable frame 34, thereby driving the adjustment mechanism 4 and the camera 5 to adjust in the vertical direction. To adjust the horizontal angle of the camera, the third motor 41 is started. The output shaft drives the movable sleeve 42 to rotate on the first housing 40. The second movable frame 43 mounted on the side of the movable sleeve 42 will rotate accordingly, thereby changing the angle of the camera in the horizontal direction. The fourth motor 48 is turned on, and the output shaft of the fourth motor 48 drives the second bevel gear 49 to rotate. The second bevel gear 49 meshes with the first bevel gear 46, causing the first bevel gear 46 to drive the threaded sleeve 45 to rotate. Because the threaded sleeve 45 is threadedly connected to the third threaded post 44, and the second housing 47 is slidably connected to the second movable frame 43, the rotation of the threaded sleeve 45 will cause the second housing 47 to slide on the second movable frame 43, thereby adjusting the horizontal position of the camera. During the entire inspection process, the operator can flexibly adjust the position and angle of the camera by controlling the operation of each motor according to the shape, size and other characteristics of the workpiece to be tested, so as to collect a comprehensive and clear image of the workpiece to be tested and complete the visual inspection work.

[0020] In summary, compared to existing technologies, this invention, in its support mechanism, uses a first motor to drive the first threaded column to rotate, allowing the first slider to slide along the fixed frame for coarse camera adjustment. A second motor drives the second threaded column to rotate, causing the second slider to move up and down on the first movable frame to adjust the camera position. A third motor in the adjustment mechanism drives the movable sleeve to rotate, causing the second movable frame to rotate accordingly, thus adjusting the camera's viewing angle. The output shaft of a fourth motor drives a second bevel gear, which meshes with the first bevel gear to rotate the threaded sleeve, causing the second housing to slide within the second movable frame to adjust the camera. This allows for flexible adjustment of the camera's position and angle in multiple dimensions, enabling rapid and precise adjustment to the optimal detection position and angle. When dealing with products with complex shapes and significant size variations, this device, with its multi-dimensional flexible adjustment capabilities, can efficiently acquire comprehensive and clear detection images.
