A machine vision measurement device

Abstract

This utility model discloses a machine vision measuring device, relating to the field of visual inspection technology. The device includes a base, with an L-shaped support frame fixedly connected to the rear side of the base. A first machine vision camera is fixedly mounted on the top of the L-shaped support frame. A tray is rotatably connected to the top of the base below the first machine vision camera via a rotating shaft. This utility model allows for scanning and measuring products from above using the first machine vision camera, and for scanning and measuring products from the side using a second machine vision camera in conjunction with the rotating tray. This eliminates the need for manual product flipping or adjustment, as well as manual adjustment of the machine vision camera's position, making operation convenient and improving product measurement efficiency. By driving the first machine vision camera to move a slide vertically, the slide can also drive the second machine vision camera vertically, thus better adapting to scanning and measuring the sides of products of different heights.

Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, and in particular relates to a machine vision measurement device. Background Technology

[0002] Machine vision systems utilize machines to perform various measurements and judgments, replacing human eyes. It is an important branch of computer science, integrating technologies from optics, mechanics, electronics, and computer hardware and software, encompassing multiple fields such as computer science, image processing, pattern recognition, artificial intelligence, signal processing, and opto-mechatronics.

[0003] Currently, machine vision systems can accurately measure the dimensions of product surfaces. However, most existing machine vision measuring devices are typically vertically mounted, allowing only top-down scanning of products. They cannot measure products with side openings, requiring frequent manual adjustments to the product angle and failing to ensure proper alignment between the product's side and the machine vision measuring device. A search revealed patent application number 202421304343.2, which discloses a machine vision measuring device belonging to the field of visual inspection technology. This device includes a worktable with a rotating platform rotatably connected to it. An electric slide rail is fixedly connected to the worktable, and a slide block is slidably connected to the slide rail. A rotating rod is rotatably connected to the slide block, with one end of the rotating rod detachably connected to a machine vision camera. The output end of the machine vision camera corresponds to the rotating platform. A rotating component and an auxiliary component are positioned between the machine vision camera and the worktable. These components work together to control the rotation of the machine vision camera, enabling it to measure the product's side.

[0004] However, in actual use, the applicant found that when scanning and measuring the side of a product, it is not convenient to adjust the machine vision camera from vertical to horizontal. Moreover, after the machine vision camera is adjusted to horizontal, its position and height cannot be adjusted, so it cannot be better suited for scanning and measuring the side of products of different heights. In view of this, we propose a machine vision measurement device. Utility Model Content

[0021] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0022] A machine vision measuring device includes a base 1, an L-shaped support frame 2 fixedly connected to the rear side of the base 1, a first machine vision camera 4 fixedly mounted on the top of the L-shaped support frame 2, a tray 7 rotatably connected to the base 1 below the first machine vision camera 4 via a rotating shaft 9, the lower end of the rotating shaft 9 being rotatably connected to the base 1 via a bearing, the tray 7 being fixedly connected to the upper end of the rotating shaft 9, and anti-slip teeth 71 evenly distributed on the peripheral side wall of the tray 7. A second machine vision camera 6 is disposed on the rear side of the tray 7, and a controller 3 is fixedly connected to one side of the L-shaped support frame 2 via a support plate 21, the support plate 21 being fixedly mounted on the L-shaped support frame. On one side of 2, a processor 8 is fixedly installed on the top of the support plate 21. The controller 3 is electrically connected to an external power supply via wires. The controller 3, the first machine vision camera 4, the electric slide rail 5, the second machine vision camera 6, and the processor 8 are electrically connected via wires. The first machine vision camera 4 can scan and measure the product from above. The second machine vision camera 6, in conjunction with the rotating tray 7, can scan and measure the product from the side. There is no need for personnel to flip and adjust the product, nor is there a need for personnel to adjust the position of the machine vision camera. The operation is convenient and can improve the measurement efficiency of the product.

[0023] The second machine vision camera 6 is fixedly mounted on the electric slide rail 5, which is fixedly mounted on the front side of the L-shaped support frame 2. A slide block 51 is slidably mounted on the electric slide rail 5. The second machine vision camera 6 is fixedly mounted on the slide block 51. By driving the electric slide rail 5, the slide block 51 is moved vertically, which can drive the second machine vision camera 6 to move vertically. This makes it more suitable for scanning and measuring the sides of products of different heights, and it is more practical.

[0024] Working principle: In use, the product to be measured can be placed on top of the tray 7, and the first machine vision camera 4 and the second machine vision camera 6 can be powered on through the controller 3. The first machine vision camera 4 can scan and measure the product from above, and the second machine vision camera 6 can scan and measure the product from the side. When scanning and measuring the product from the side, the tray 7 can be manually moved to rotate the product on it, so as to achieve scanning and measurement of the product's perimeter. When the product is high, the controller 3 can also drive the electric slide rail 5 to move the slide 51 vertically, and the slide 51 can move the second machine vision camera 6 vertically to adjust the position and height of the second machine vision camera 6 to meet the needs of scanning and measuring the perimeter of products of different heights. The scanning and measurement data of the first machine vision camera 4 and the second machine vision camera 6 can be transmitted to the processor 8 for analysis and processing. The data processed by the processor 8 can be transmitted to the controller 3, and the measurement data can be displayed on the display screen of the controller 3.
