Description

Technical Field

[0001] The present application relates to the field of bar material detection equipment, and in particular to a bar material size detection device. Background Art

[0002] In the production process of the alloy workshop, the outer diameter and length of the alloy bars after sintering often fluctuate greatly. In order to ensure product quality and prevent products with unqualified dimensions from entering the subsequent process, it is currently necessary to rely on specialized personnel and cumbersome procedures to carry out the corresponding inspection work. Specifically, the existing inspection methods mostly rely on manual measurement using calipers. The outer diameter of each alloy bar needs to be measured at three different positions: the front end, the middle end, and the back end. After the measurement is completed, these values ​​are manually recorded. This process is not only cumbersome to operate, but also because alloy bars have a variety of outer diameters and length specifications, manual measurement also has a large risk of error.

[0003] At the same time, there are also detection equipment for detecting the size of rods on the market. Although these detection equipment can detect the size of rods, they have poor applicability when detecting rods of different specifications.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Existing bar size detection methods mainly include manual methods and detection methods using detection equipment. The former has the problem of low detection efficiency, while the latter has the problem of poor applicability to detection of bars of different specifications.

[0036] In order to solve the above technical problems, this embodiment provides a bar size detection device. Figures 1 to 4 As shown, Figure 1 This is a three-dimensional diagram of the bar size detection device in the embodiment of the present application. Figure 2 : is a top view of the bar size detection device in the embodiment of the present application, Figure 3 : is a side view of the bar size detection device in the embodiment of the present application, Figure 4 It is a three-dimensional diagram of the adjustment mechanism in the embodiment of the present application.

[0037] The bar size detection device of this embodiment includes: a positioning fixture 1, a limit plate 2, a visual detection device 3, a linear drive mechanism 4, a grating ruler 5, a backlight source 6, an adjustment mechanism 7 and a frame 8.

[0038] The positioning fixture 1 and the limiting plate 2 form a positioning assembly, which is used to position the bar to be tested at a preset position. The positioning fixture 1 and the limiting plate 2 are provided. Figure 1 As shown, the positioning fixture 1 is fixedly connected to the frame 8 and has a V-shaped groove 10 for placing the rod. The V-shaped groove 10 extends in a straight line, allowing the rod to be automatically centered. A limit plate 2 is fixedly arranged in the extension direction of the V-shaped groove 10, such as fixed to the frame 8, to limit one end of the rod.

[0039] The visual inspection device 3 is used to take photos and detect the dimensions of the bar. It is movably arranged on the frame 8 and located above the positioning fixture 1.

[0040] The linear drive mechanism 4 is disposed on the frame 8 and connected to the visual inspection device 3 , and is configured to drive the visual inspection device 3 to move in a direction parallel to the V-shaped groove 10 .

[0041] The grating ruler 5 is arranged on the frame 8 and is parallel to the V-groove 10 .

[0042] The backlight source 6 and the adjustment mechanism 7 form a backlight source assembly. The backlight source 6 is located below the positioning jig 1 and is set toward the positioning jig 1. The adjustment mechanism 7 is provided on the frame 8 and connected to the backlight source 6. It is configured to adjust the relative position and / or angle of the backlight source 6 and the positioning jig 1.

[0043] When the bar size detection device of the above technical solution is working, first, the bar to be detected is placed in the V-groove 10 of the positioning fixture 1 of the positioning assembly. The design of the V-groove 10 enables the bar to be placed stably and extend in a straight line, ensuring that the bar will not shift or roll during the detection process. Next, the limiting plate 2 is used to limit one end of the bar to ensure that the position of the bar in the V-groove 10 is fixed, providing a stable detection environment for subsequent visual inspection. The backlight source 6 is then adjusted: the relative position and / or angle of the backlight source 6 and the positioning fixture 1 is adjusted by the adjustment mechanism 7. After the adjustment is completed, the backlight source 6 will emit light to illuminate the bar placed in the V-groove 10, ensuring that the backlight source 6 can evenly illuminate the bar, so that the visual inspection device 3 can capture a clear and accurate image. Then the visual inspection device 3 moves and inspects: the linear drive mechanism 4 is responsible for driving the visual inspection device 3 to move in a direction parallel to the V-groove 10; when the visual inspection device 3 starts to move, it will capture the image of the rod. Due to the uniform illumination of the backlight source 6, the visual inspection device 3 can obtain high-quality image data. The visual inspection device 3 can be equipped with existing image processing algorithms or software for analyzing and processing the captured images. These algorithms or software can identify dimensional features such as the outer diameter of the rod and can be compared with preset standard dimensions. In this process, the grating ruler 5 is used to assist in positioning: the grating ruler 5 is a high-precision displacement measuring device used to detect the position of the visual inspection device 3 during movement. By reading the data of the grating ruler 5, the moving distance of the visual inspection device 3 can be accurately controlled, and the length of the rod can be calculated based on the moving distance from the head end to the end of the rod. Finally, the inspection results are output: After image processing and analysis, the visual inspection device 3 will output the size inspection results of the bar. These results may include information such as the actual size of the bar, the deviation from the standard size, etc. Based on the inspection results, it can be judged whether the bar meets the production requirements. If the bar size does not meet the requirements, it can be adjusted or replaced in time to ensure product quality.

[0044] It can be seen that the bar size detection device of the above technical solution realizes the positioning of the bar through the V-groove 10 and the limit plate 2 of the positioning fixture 1, which not only simplifies the positioning process, but also ensures the accuracy and stability of the positioning. Moreover, the universal design of the V-groove 10 can adapt to bars of various outer diameters. Combined with the flexible application of the limit plate 2, the device can quickly and accurately position bars of different sizes. The visual inspection device 3 is driven by the linear drive mechanism 4 to move smoothly along the entire length of the bar, accurately measure the outer diameter of each detection point of the bar, and simultaneously record the moving distance of the visual inspection device 3 on the grating scale 5, so as to calculate the length of the bar and improve the detection efficiency. In addition, the backlight source component can adjust its relative position and / or illumination angle with the positioning fixture 1 according to the size of the bar through the adjustment mechanism 7, providing optimized backlighting for bars of different sizes, significantly improving the measurement accuracy and reliability of the visual inspection device 3.

[0045] Exemplarily, the positioning jig 1 uses a light-transmitting material, such as a diffuse reflector as the backlight source 6 , so that the backlight source 6 can illuminate the rod through the positioning jig 1 to enhance the lighting effect.

[0046] In an embodiment in which the adjustment mechanism 7 is disposed on the frame 8 and connected to the backlight source 6, see Figure 3 and Figure 4 As shown, the adjustment mechanism 7 includes an adjustment plate 71, which is mounted on the frame 8 and located below the positioning jig 1. The adjustment plate 71 is provided with an adjustment hole 701, which extends in the height direction. The backlight source 6 is fixed to the adjustment hole 701 by bolts. The adjustment hole 701 extends in the height direction, providing a flexible installation position for the backlight source 6. The backlight source 6 is securely fixed to the adjustment hole 701 by bolts, thereby achieving adjustment of the relative height position between the backlight source 6 and the positioning jig 1. This allows the backlight source 6 to provide optimized illumination for bars of different sizes, greatly improving the measurement accuracy of the visual inspection device 3.

[0047] Exemplarily, two adjustment holes 701 are provided and are parallel to each other, and one end of the backlight source 6 is connected to the two adjustment holes 701 simultaneously through two bolts.

[0048] Exemplarily, at least one adjustment plate 71 is provided at each of the two opposite ends of the backlight source 6 , and the adjustment plates 71 are parallel to each other, thereby improving the firmness of the installation of the backlight source 6 and the stability of the adjustment operation.

The adjustment plate 71 is rotatably connected to the mounting plate 72 via a rotating shaft. To increase stability during the adjustment process, a damping structure is also provided between the adjustment plate 71 and the mounting plate 72, making the angle adjustment process more stable and controllable. When adjusting the angle of the backlight source 6, the adjustment plate 71 can be rotated so that the adjustment plate 71 rotates about the rotating shaft, thereby changing the illumination angle of the backlight source 6. This further enhances the flexibility of the backlight source 6 and the lighting effect.

During operation, the drive member 75 controls the rotation of the gear 73, and the gear 73 drives the two racks 74 to move in opposite directions, thereby driving the two groups of backlight sources 6 to move closer to or further away from each other, thereby adjusting the relative position of the backlight source 6 and the positioning fixture 1 in the horizontal direction; at the same time, the two groups of backlight sources 6 can provide light from both sides of the positioning fixture 1, which can improve the uniformity of light and further improve the accuracy of the detection results.

[0052] Exemplarily, the two groups of backlight sources 6 move in opposite directions with the positioning fixture 1 as the center.

[0053] Exemplarily, the driving member 75 can manually control the rotation of the gear 73, such as the driving member 75 is a handwheel or a handle; the driving member 75 can also automatically control the rotation of the gear 73, such as the driving member 75 is a motor and is connected to the gear 73.
