[0025] Example:

[0026] See also Figure 1-4 A machine vision measuring device includes a workbench 1, a rotating table 2 is rotatably connected to the workbench 1, an electric slide rail 3 is fixedly connected to the workbench 1, a slide seat 4 is slidably connected to the electric slide rail 3, a rotating rod 5 is rotatably connected to the slide seat 4, one end of the rotating rod 5 is detachably connected to a machine vision camera 6, and the output end of the machine vision camera 6 corresponds to the rotating table 2, a rotating component and an auxiliary component are arranged between the machine vision camera 6 and the workbench 1, and the rotating component and the auxiliary component cooperate to control the machine vision camera 6 to rotate, so as to realize the machine vision camera 6 to measure the side of the product.

[0027] In this embodiment, when measuring the size of the product, the product is placed on the rotating table 2, and the electric slide 3 controls the movement of the slide 4. The slide 4 drives the machine vision camera 6 to move through the rotating rod 5, so that the machine vision camera 6 is adjusted to a suitable position to measure various dimensions on the product. When the slide 4 slides to the position closest to the bottom end on the electric slide 3, the rotating assembly and the auxiliary assembly cooperate to rotate the rotating rod 5 90°, and the rotating rod 5 drives the machine vision camera 6 to rotate 90°, so that the machine vision camera 6 corresponds to the side of the product on the rotating table 2, and the product is driven to rotate by the rotating table 2, so that multiple sides of the product are scanned and measured by the machine vision camera 6; the machine vision camera 6 is common knowledge to technicians in this field and will not be described in detail in this solution.

[0028] Specifically, the rotating assembly includes an intermittent gear 71 and a rack 72 . The intermittent gear 71 is fixedly connected to the outer surface of the rotating rod 5 . The rack 72 is fixedly connected to the workbench 1 , and the rack 72 corresponds to the intermittent gear 71 .

[0029] In this embodiment, when the machine vision camera 6 measures the side of the product, the electric slide rail 3 controls the slide 4 to move downward through an external power supply, and the slide 4 drives the machine vision camera 6 to move downward through the rotating rod 5. The continuous downward movement of the slide 4 will cause the intermittent gear 71 and the rack 72 to engage and contact, and the intermittent gear 71 drives the rotating rod 5 to rotate 90°, so that the machine vision camera 6 rotates to one side of the product to measure the side.

[0030] Specifically, the auxiliary component includes a slider 81, an auxiliary strip 82, a slide 83 and a swivel 84. The slider 81 is fixedly connected to the outer surface of the rotating rod 5, the auxiliary strip 82 is fixedly connected to the workbench 1, the slide 83 and the swivel 84 are both opened on the auxiliary strip 82 and interlinked, and the workbench 1 is slidably connected in the slide 83.

[0031] In this embodiment, when the slide seat 4 drives the rotating rod 5 to move downward, the rotating rod 5 drives the slider 81 to slide in the sliding mouth 83, thereby ensuring the stability of the rotating rod 5 when moving. When the intermittent gear 71 contacts the rack 72 to control the rotation of the rotating rod 5, the slider 81 moves from the sliding mouth 83 to the rotating mouth 84. The rotating mouth 84 provides a rotating space for the slider 81, so that the rotating rod 5 can rotate stably.

[0032] Specifically, a fixing plate 9 is fixedly connected to the workbench 1 , and the electric slide rail 3 is fixedly connected to the fixing plate 9 .

[0033] In this embodiment, the fixing plate 9 is used to fix the electric slide rail 3 so that the electric slide rail 3 can stably operate to control the lifting of the machine vision camera 6 .

[0034] Specifically, a rotating sleeve 10 is fixedly connected to the outer surface of the rotating table 2, and anti-slip patterns are engraved on the rotating sleeve 10.

[0035] In this embodiment, the rotation of the rotating table 2 is made more convenient by the rotating sleeve 10 and the anti-slip grooves on its surface.

[0036] Working principle: When measuring the product size, the product is placed on the rotating table 2, and the electric slide 3 controls the movement of the slide 4 through an external power supply. The slide 4 drives the machine vision camera 6 to move through the rotating rod 5, so that the machine vision camera 6 is adjusted to a suitable position to measure various sizes on the product. When measuring the side of the product, the electric slide 3 controls the slide 4 to move downward through an external power supply. The slide 4 drives the machine vision camera 6 to move downward through the rotating rod 5. The rotating rod 5 maintains a stable downward movement through the sliding connection between the slider 81 and the auxiliary bar 82. The continuous downward movement of the slide 4 will cause the intermittent gear 71 and the rack 72 to engage and contact. At the same time, the slider 81 will enter the sliding mouth 83, and the intermittent gear 71 will drive the rotating rod 5 to rotate 90°, so that the machine vision camera 6 rotates to one side of the product to measure the side. The product is driven to rotate by the rotating table 2, so that multiple sides of the product are scanned and measured by the machine vision camera 6.

[0037] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
