Description

Technical Field

[0001] This utility model relates to the field of wear-resistant ball production technology, specifically to a device for detecting the roundness of wear-resistant balls. Background Technology

[0002] In modern mining, cement plant, chemical plant, and silica sand plant production processes, wear-resistant balls play a crucial role in the dry grinding stage. As a dry grinding material, the roundness of the wear-resistant balls affects the quality of ore dry grinding and significantly shortens their lifespan, leading to increased costs and impacting production efficiency and product quality. Therefore, roundness error detection is of great importance for evaluating the quality of wear-resistant balls.

[0003] Traditional wear-resistant ball inspection relies on contact-based manual methods, which suffer from low accuracy, high labor intensity, and inconsistent inspection standards. In modern industrial production, visual inspection is widely used across various industries. With industrial development, the demand for wear-resistant balls in some sectors is increasing. Currently, wear-resistant ball production in these industries still relies on automated forging on assembly lines, with manual inspection remaining the primary method. This results in low efficiency, high labor intensity, and high labor costs, severely hindering enterprise development. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a device for detecting the roundness of wear-resistant balls, addressing the above-mentioned shortcomings. This invention uses a ramp to transport the wear-resistant balls, and employs a visual inspection method to detect their roundness during the rolling process, thereby significantly improving the efficiency of roundness detection.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A device for detecting the roundness of wear-resistant spheres includes a detection ramp, a detection unit, and a sorting unit.

[0007] The detection unit is positioned above the detection ramp, and is used to photograph the wear-resistant balls on the detection ramp.

[0008] The output end of the detection ramp includes a first discharge channel and a second discharge channel.

[0009] The sorting unit is located between the first discharge channel and the second discharge channel, and the sorting unit is used to guide the wear-resistant balls into the first discharge channel or the second discharge channel.

[0010] Furthermore, the detection unit includes a camera and a light source.

[0011] Furthermore, the camera and light source are covered with several light-shielding plates to form a light-shielding space covering the camera, light source and part of the detection ramp.

[0012] Furthermore, the detection unit also includes a frame, on which the camera, light source, and light shield are all mounted.

[0013] Furthermore, the light-shielding plate is provided with through holes for detecting the passage of the ramp.

[0014] Furthermore, the dispensing unit includes a dispensing plate, a base, a connecting rod, and a pushing mechanism. The base is disposed between the first discharge channel and the second discharge channel. The dispensing plate is rotatably disposed on the base.

[0015] Furthermore, the detection ramp includes a first ramp section, a second ramp section, and a third ramp section connected in sequence. The detection unit is located at the second ramp section, and the third ramp section is provided with a first discharge channel and a second discharge channel.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1:

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a wear-resistant ball roundness testing device includes a testing ramp 1, a testing unit 2, and a sorting unit 3.

[0030] The inspection ramp 1 is used to realize the rolling conveying of the wear-resistant balls 5. The inspection ramp 1 is composed of a first ramp section 11, a second ramp section 12 and a third ramp section 13 connected in sequence. The bottom of the first ramp section 11 and the third ramp section 13 are provided with a frame for supporting the ramp section. The first ramp section 11, the second ramp section 12 and the third ramp section 13 are all inclined downward towards the end of the third ramp section 13.

[0031] The third slope section 13 has a first discharge channel 1a and a second discharge channel 1b. In this embodiment, the first discharge channel 1a and the second discharge channel 1b are arranged in a "y" shape.

[0032] The detection unit 2 is used to photograph the wear-resistant balls on the detection ramp 1 to achieve roundness detection;

[0033] The detection unit 2 is set at the second slope section 12. The detection unit 2 includes a camera 21, a light source 22 and a frame 23. The camera 21 and the light source 22 are both set on the frame 23, and the camera 21 and the light source 22 are both located above the second slope section 12. The shooting end of the camera 21 faces the second slope section 12, and the light source 22 is located below the shooting end of the camera 21.

[0034] The outer side of the frame 23 is also covered with multiple light shields 4. The light shields 4 cover the camera, the light source 22 and part of the second slope section 12 to form a light shielding space 4a to prevent external light from affecting the shooting of the camera 21.

[0035] Furthermore, the light-shielding plate 4 has through holes 41, and there are two through holes 41. The two ends of the second slope section 12 pass through the through holes 41, and the wear-resistant ball 5 can also pass through the light-shielding space 4a through the through holes 41.

[0036] like Figure 4 and Figure 5 As shown, the dispensing unit 3 includes a dispensing plate 31, a base 32, a connecting rod 33, and a pushing mechanism 34. The base 32 is disposed between the first discharge channel 1a and the second discharge channel 1b. The dispensing plate 31 is rotatably disposed on the base 32. One end of the connecting rod 33 is fixedly connected to the dispensing plate 31, and the other end of the connecting rod 33 is hinged to the moving end of the pushing mechanism 34.

[0037] Furthermore, a hinge frame 35 is provided at the bottom of the third slope section 13, and the pushing mechanism 34 is a pushing cylinder. The pushing mechanism 34 is located below the third slope section 13, and one end of the pushing mechanism 34 is hinged to the hinge frame 35. The push rod of the pushing mechanism 34 is hinged to the connecting rod 33. A rotating shaft extends from the bottom of the dial plate 31, and the other end of the connecting rod 33 is fixed to the rotating shaft of the dial plate 31.

[0038] When the pushing mechanism 34 is used to push the dial plate 31 to rotate via the connecting rod 33, so that the dial plate 31 blocks the first discharge channel 1a or the second discharge channel 1b, the wear-resistant balls are discharged from the second discharge channel 1b or from the first discharge channel 1a.

[0039] In use, the wear-resistant ball 5 is placed at the input end of the detection ramp 1, and the wear-resistant ball 5 rolls along the detection ramp 1. When the wear-resistant ball 5 moves to below the camera 21, the camera 21 captures several images of the wear-resistant ball 5. The computer then processes the images to determine whether the roundness of the wear-resistant ball 5 meets the requirements. If it meets the requirements, the wear-resistant ball 5 is discharged from the first discharge channel 1a through the sorting unit 3. If it does not meet the requirements, the wear-resistant ball 5 is discharged from the second channel 1b through the sorting unit 3.

[0040] Specifically, camera 21 uses a CCD camera and employs backlighting to capture the contour edge of the wear-resistant ball. During the detection process, the contour edge of the wear-resistant ball is first acquired through the camera, and then the image is transmitted to the computer in real time via wired or wireless means.

[0041] In this embodiment, the Sobel algorithm is used for pixel-level coarse localization of the wear-resistant ball edges in the image, followed by sub-pixel precision edge extraction using the Zernike moment detection algorithm. Finally, the least squares method is used to fit the roundness of the wear-resistant ball, and the ideal center position is determined by the coordinates of the edge points of the wear-resistant ball. The above only describes how to extract the edges of the wear-resistant ball in the image and how to determine the center of the wear-resistant ball. Extracting the contour edges in the image is something that those skilled in the art can do, and the method of calculating roundness is also common knowledge, so it will not be elaborated on here.

[0042] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
