Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, and more specifically, relates to an adjustment device for industrial visual inspection. Background Technology

[0002] Industrial vision inspection utilizes computer vision technology to automate the quality inspection of products and control related production processes in industrial production. It uses high-speed cameras and image processing software to capture and analyze product images in real time.

[0003] The utility model patent with application number CN201920106884.7 (announcement number CN209170519U) provides a novel industrial camera visual laser illumination imaging device, which includes a camera bracket, an industrial camera, etc. The camera bracket includes a camera bracket base plate, a camera fixing bracket, and a camera fixing pillar. The camera fixing pillar is fixed on the camera bracket base plate, and the camera fixing bracket is fixed at the upper part of the camera fixing pillar.

[0004] The camera in the aforementioned patent is in a fixed position and cannot be adjusted in height and angle according to the height and size of the object being measured. It cannot effectively detect larger objects, and the camera position cannot be adjusted again during the detection process, which limits its use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an adjustment device for industrial visual inspection, which solves the technical problem that the camera is in a fixed position, making it inconvenient to adjust its height and angle, thus limiting its use.

[0006] This utility model is implemented as follows:

[0007] This utility model provides an adjustment device for industrial visual inspection, which has a base on which an object to be measured is placed. A vertical plate is fixedly installed at the rear end of the top wall of the base, and a support plate is provided at the front end of the vertical plate. An adjustment plate is provided at the front end of the support plate, and a camera body is installed on the adjustment plate.

[0008] Based on the above technical solution, the adjustment device for industrial visual inspection of this utility model can be further improved as follows:

[0009] Furthermore, a ball screw is provided on the front wall of the upright plate, the nut of the ball screw moves vertically and a support seat is fixedly installed on its outer circumference, and a support plate is fixedly installed on the front wall of the support seat.

[0010] Furthermore, the ball screw is symmetrically provided with linear slide rails fixedly installed on the vertical plate on both the left and right sides. Each linear slide rail is slidably connected to a slider, and the four sliders are fixedly installed at the four corners of the rear wall of the support plate.

[0011] Furthermore, two horizontally symmetrical outer plates are fixedly connected to the front wall of the support plate, and a rotating column is rotatably connected to each of the two outer plates. An adjustment plate is fixedly installed between the rotating columns.

[0012] Furthermore, a circumferentially rotating sleeve is provided between the two outer plates, and a guide rod is slidably connected inside the sleeve. The two ends of the guide rod are respectively fixedly installed on the inner plates, and the front ends of the two inner plates are symmetrically fixedly installed on the rotating column.

[0013] Furthermore, the support plate has a driven gear rotatably connected in the middle, and a driving gear meshing with it is provided below the driven gear. One end of a connecting rod is fixedly installed on the outer edge of the front wall of the driven gear, and the front end of the connecting rod is fixedly installed in the middle of the sleeve.

[0014] Compared with existing technologies, the advantages of the adjustment device for industrial visual inspection provided by this utility model are:

[0015] By vertically moving the support plate and rotating the adjustment plate around its horizontal axis centerline, the height position and pitch angle of the camera can be adjusted so that the object to be measured can occupy a suitable position and size within the camera's field of view. This allows for the adjustment of the camera's height position and pitch angle, meeting the visual acquisition needs of different angles and further reducing blind spots.

[0016] By adjusting the angle, obstructions and reflections can be avoided. When the object under test has protruding structures, holes, or reflective surfaces, fine-tuning the camera angle (e.g., ±10°~30°) can avoid obstructed areas or reduce interference from ambient light and reflections from the detection light source, ensuring clear imaging of the detection area. It can also focus on local details; for object edges, seams, and minor defects (such as cracks and bubbles), fine-tuning the angle can change the shooting perspective, making the details more prominent. By rotating the driving gear, which in turn rotates the sleeve on the driven gear, the angle of the adjustment plate can be adjusted. This slows down the rotation, preventing excessively fast rotation and making angle adjustment inconvenient.

[0017] By setting a ball screw, the balls roll between the screw and the nut to transmit motion, enabling precise displacement control during transmission. Attached Figure Description

[0033] Optionally, in the above technical solution, a ball screw 20 is provided on the front wall of the upright plate 2, the nut 22 of the ball screw 20 moves vertically, and a support seat 23 is fixedly installed on the outer circumferential surface, and a support plate 24 is fixedly installed on the front wall of the support seat 23.

[0034] Optionally, in the above technical solution, linear slide rails 31 are symmetrically provided on the left and right sides of the ball screw 20 and fixedly installed on the vertical plate 2. Each linear slide rail 31 is slidably connected to a slider 32, and the four sliders 32 are fixedly installed at the four corners of the rear wall of the support plate 24.

[0035] Optionally, in the above technical solution, two horizontally symmetrical outer plates 41 are fixedly connected to the front wall of the support plate 24, and a rotating column 42 is rotatably connected to each of the two outer plates 41. An adjustment plate 4 is fixedly installed between the rotating columns 42.

[0036] Optionally, in the above technical solution, a circumferentially rotating sleeve 45 is provided between the two outer plates 41, and a guide rod 46 is slidably connected inside the sleeve 45. The two ends of the guide rod 46 are respectively fixedly installed on the inner plate 48, and the front ends of the two inner plates 48 are symmetrically fixedly installed on the rotating column 42.

[0037] Optionally, in the above technical solution, the support plate 24 is provided with a driven gear 43 rotatably connected in the middle, and a driving gear 47 meshing with it is provided below the driven gear 43. One end of a connecting rod 44 is fixedly installed on the outer edge of the front wall of the driven gear 43, and the front end of the connecting rod 44 is fixedly installed in the middle of the sleeve 45.

[0038] Among them, the support base 23 is a square block with a vertical through hole in the middle, so that the circumferential surface of the nut 22 can be inserted into the through hole of the support base 23 for fixed connection.

[0039] Furthermore, two vertically arranged ear plates 25 are fixedly installed in the middle of the upright plate 2, and the upper and lower ends of the screw 21 of the ball screw 20 are rotatably connected to the ear plates 25 through bearings.

[0040] Furthermore, a motor base A26 is fixedly installed at the top center of the upright plate 2, and a motor A27 is fixedly installed on the motor base A26. The output shaft of the motor A27 extends downward and is connected to the lead screw 21 of the ball screw 20 through a coupling.

[0045] In use, the camera is fixedly mounted on the adjustment plate 4 with the camera lens facing downwards. The object to be measured is placed on the base 1, and the camera takes a picture of the object. After the picture is taken, the digital signal of the image (pixel distribution, brightness, color and other information) is transmitted to a dedicated image processing system (such as a computer or embedded image processor) via a data cable (such as USB or Ethernet). The height and angle of the camera on the adjustment plate 4 are adjusted according to the object to be measured. After the camera is fixed on the adjustment plate 4, multiple adjustments can be made.

[0046] The height adjustment method is as follows: start motor A27 to drive the ball screw 20 screw 21 to rotate in place in ear plate 25, thereby causing nut 22 to drive support seat 23 to move up and down, support plate 24 to move vertically along linear slide rail 31 through slider 32, thereby adjusting the height position of camera on adjustment plate 4;

[0047] The angle adjustment method is as follows: start motor B34 to drive the drive gear 47 to rotate in place, drive the driven gear 43 meshing with it to rotate in place, and link 44 drives sleeve 45 to make circular motion around the center of driven gear 43. During the movement of sleeve 45, it drives the guide rod 46 slidably connected to it to swing up and down, so that the rotating column 42 fixed by inner plate 48 is in place in outer plate 41, driving the adjustment plate 4 to tilt up or down, thereby adjusting the pitch angle of the camera.
