Detailed Implementation
[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0030] Please see Figures 1-4 This application discloses a transmission belt detection device, including a detection frame 1 and a detection mechanism. The detection mechanism is disposed on the detection frame 1 and supported by the detection frame 1. The detection mechanism includes at least one detection component 2, which includes a base 21, an image extraction component 22, and a drive component and an unloading component disposed on the base 21. The drive component includes a drive unit 231, a first transmission component 232 connected to and driven by the drive unit 231, and a second transmission component 233 connected to the first transmission component 232. The second transmission component 233 includes a first transmission pulley 2331 and a second transmission pulley 2332 arranged side by side, and a third transmission pulley 2333 located below the first transmission pulley 2331 and the second transmission pulley 2332. The first transmission pulley 2331 and the second transmission pulley 2332 are both connected to the first transmission component 232, and the third transmission pulley 2333 can move in the vertical direction.
[0031] The base 21 is fixed on the inspection frame 1. The image extraction component 22 is used to acquire images of the transmission belt. The transmission belt to be inspected is positioned on the drive component and rotated by the drive component, facilitating comprehensive defect detection of the transmission belt by the image extraction component 22. The transmission belt to be inspected is fitted and tensioned on the first transmission pulley 2331, the second transmission pulley 2332, and the third transmission pulley 2333. The first transmission component 232 drives the first transmission pulley 2331 and the second transmission pulley 2332 to rotate, causing the transmission belt to be inspected and the third transmission pulley 2333 to rotate, facilitating comprehensive and rapid image acquisition of the transmission belt by the image extraction component 22. The third transmission pulley 2333 can be adjusted in the vertical direction, facilitating the fitting and tensioning of transmission belts of different lengths on the first transmission pulley 2331, the second transmission pulley 2332, and the third transmission pulley 2333, making it suitable for the inspection of transmission belts of different lengths.
[0032] Please see Figure 3 The first drive pulley 2331 is a frustum-shaped cone, wider at the outer edge and narrower at the inner edge, while the second drive pulley 2332 is a frustum-shaped cone, narrower at the outer edge and wider at the inner edge. The use of two tapers in different directions causes the drive belt to twist slightly as it passes through the first and second drive pulleys 2331 and 2332. This allows the image extraction component 22 to more clearly capture the side structure of the drive belt, facilitating the identification of defects such as whether the cords have separated from the rubber. The direction from which the drive belt to be inspected is grasped in the previous process and then fitted onto the first and second drive pulleys 2331 and 2332 is from the outside in. It is understood that the first drive pulley 2331 can also be configured as a frustum-shaped cone, narrower at the outer edge and wider at the inner edge, in which case the second drive pulley 2332 would be a frustum-shaped cone, wider at the outer edge and narrower at the inner edge.
[0033] Please see Figure 2 , Figure 3The detection component 2 also includes a limiting component, which includes a first limiting member 251 and a second limiting member 252. The first limiting member 251 includes a first limiting wheel 2511, which cooperates with the first transmission pulley 2331. The second limiting member 252 includes a second limiting wheel 2521, which cooperates with the second transmission pulley 2332. Both the first limiting wheel 2511 and the second limiting wheel 2521 are conical. The cone shape of the first limiting wheel 2511 is opposite to that of the first transmission pulley 2331, and the cone shape of the second limiting wheel 2521 is opposite to that of the second transmission pulley 2332. When the first drive pulley 2331 is a frustum shape with a larger outer diameter and a smaller inner diameter, and the second drive pulley 2332 is a frustum shape with a smaller outer diameter and a larger inner diameter, then the first limiting wheel 2511 is a cone shape with a smaller outer diameter and a larger inner diameter to match the first drive pulley 2331, and the second limiting wheel 2521 is a cone shape with a larger outer diameter and a smaller inner diameter to match the second drive pulley 2332. The arrangement of the first limiting wheel 2511 and the second limiting wheel 2521 can press down on the drive belt to be detected, preventing the belt from buckling after twisting, thus facilitating image acquisition. It can be understood that when the first drive pulley 2331 is a frustum shape with a smaller outer diameter and a larger inner diameter, and the second drive pulley 2332 is a frustum shape with a larger outer diameter and a smaller inner diameter, then the first limiting wheel 2511 is a cone shape with a larger outer diameter and a smaller inner diameter to match the first drive pulley 2331, and the second limiting wheel 2521 is a cone shape with a smaller outer diameter and a larger inner diameter to match the second drive pulley 2332.
[0034] To facilitate the first limiting wheel 2511 and the second limiting wheel 2521 pressing against or separating from the transmission belt to be tested, the first limiting member 251 preferably further includes a first rotary cylinder 2512. The first rotary cylinder 2512 is connected to and drives the first limiting wheel 2511, so that the first limiting wheel 2511 can cooperate with the outside of the first transmission pulley 2331 to limit its passage through the transmission belt between the first transmission pulley 2331 and the first limiting wheel 2511. The second limiting member 252 further includes a second rotary cylinder 2522. The second rotary cylinder 2522 is connected to and drives the second limiting wheel 2521, so that the second limiting wheel 2521 can cooperate with the outside of the second transmission pulley 2332 to limit its passage through the transmission belt between the second transmission pulley 2332 and the second limiting wheel 2521. The fixed end of the first rotary cylinder 2512 is fixed, the first limiting wheel 2511 is rotatably connected to the output end of the first rotary cylinder 2512, the fixed end of the second rotary cylinder 2522 is fixed, and the second limiting wheel 2521 is rotatably connected to the output end of the second rotary cylinder 2522.
[0035] To remove impurities from the transmission belt for clearer image acquisition, it is preferable that the second rotary cylinder 2522 is connected to a brush 2523. The second rotary cylinder 2522 can drive the brush 2523 to press onto the transmission belt to be inspected or rotate it to separate it from the transmission belt. It is understood that a brush can also be connected to the first rotary cylinder 2512, or both the first rotary cylinder 2512 and the second rotary cylinder 2522 can be connected to brushes.
[0036] Preferably, the drive unit 231 includes a drive motor 234, and the first transmission assembly 232 includes a first synchronous pulley 2321 driven by the drive motor 234 and a second synchronous pulley 2323 connected to the first synchronous pulley 2321 via a synchronous belt 2322. The first synchronous pulley 2321 and the second synchronous pulley 2323 are respectively connected to the second transmission pulley 2332 and the first transmission pulley 2331.
[0037] The detection assembly 2 also includes a mounting plate 261, a linear drive unit 262 connected to the mounting plate 261, and a support 263 connected to the linear drive unit 262. A third transmission pulley 2333 is rotatably connected to the support 263. The mounting plate 261 is fixed to the detection frame 1. The linear drive unit 262 is a combination structure of a motor and a lead screw. It is understood that the linear drive unit 262 could also be a linear motor, a motor and a rack and pinion assembly, etc., and is not limited here. Driven by the linear drive unit 262, the support 263 drives the third transmission pulley 2333 to move vertically.
[0038] To achieve unloading after transmission belt inspection, the unloading assembly preferably includes two first unloading components 241 arranged side by side. The two first unloading components 241 are respectively disposed on both sides of the second transmission assembly 233. Each first unloading component 241 includes a first unloading cylinder 2411 and an unloading rod 2412 connected to the first unloading cylinder 2411. Specifically, the two first unloading components 241 are located on both sides of the first transmission pulley 2331 and the second transmission pulley 2332, respectively, for pushing the transmission belt out in the width direction. The fixed end of the first unloading cylinder 2411 is fixed to the base 21, and the output end of the first unloading cylinder 2411 drives the unloading rod 2412 to move outward, pushing the transmission belt away from the first transmission pulley 2331, the second transmission pulley 2332, and the third transmission pulley 2333.
[0039] To facilitate smoother unloading of the drive belt, the preferred unloading assembly further includes a second unloading component 242 located above the two first unloading components 241. The second unloading component 242 includes a second unloading cylinder 2421 and an unloading block 2422 connected to the second unloading cylinder 2421. The fixed end of the second unloading cylinder 2421 remains stationary, while the output end of the second unloading cylinder 2421 drives the unloading block 2422 to move outward, further pushing the drive belt away from the first drive pulley 2331, the second drive pulley 2332, and the third drive pulley 2333.
[0040] The preferred image extraction component 22 includes four cameras, two of which are horizontally positioned opposite each other to capture images of the two sides of the conveyor belt, and the other two are vertically positioned opposite each other to capture images of the back and bottom surfaces of the conveyor belt. It is understood that the number of cameras is not limited to four; five or more cameras can be used to extract images of the conveyor belt more comprehensively. An X-ray device can also be included, positioned at the bend of the conveyor belt on the first pulley 2331 or the second pulley 2332, to capture images of the cross-section of the conveyor belt and determine the presence of air bubbles and the varying heights of the strands within the belt.
[0041] In order to better focus and position the camera, thereby better extracting the image of the bottom surface of the transmission belt, the camera used to photograph the bottom surface of the transmission belt is preferably located directly below the gap formed by the first transmission pulley 2331 and the second transmission pulley 2332.
[0042] Four cameras are set up as a first camera 221, a second camera 222, a third camera 223, and a fourth camera 224. The first camera 221 and the second camera 222 are horizontally opposite each other, facing the two sides of the transmission belt respectively. The third camera 223 and the fourth camera 224 are vertically opposite each other. The third camera 223 is located above the transmission belt and faces the back of the transmission belt. The fourth camera 224 is located directly below the gap formed by the first transmission pulley 2331 and the second transmission pulley 2332 to photograph the bottom surface of the transmission belt.
[0043] To improve testing efficiency, the preferred testing mechanism includes two testing components 2 arranged side by side. Good product racks 11 are set on both sides of the testing frame 1 to store the transmission belts that have passed the testing of the two testing components 2. A defective product box is also set between the two testing components 2.
[0044] In use, the present invention involves first gripping the transmission belt to be inspected in the previous step and placing it on the first transmission pulley 2331 and the second transmission pulley 2332. The first rotary cylinder 2512 drives the first limiting wheel 2511 to rotate, and the second rotary cylinder 2522 drives the second limiting wheel 2521 to rotate, pressing them onto the transmission belt. The linear drive unit 262 drives the third transmission pulley 2333 to adjust its position vertically, thus tensioning the transmission belt on the first, second, and third transmission pulleys. The drive motor 234 starts, driving the first and second transmission pulleys 2331 and 2332 to rotate via the first transmission assembly 232, causing the transmission belt to be inspected and the third transmission pulley 2333 to rotate. The first camera 221, the second camera 222, the third camera 223, and the fourth camera 224 comprehensively and rapidly capture images of the transmission belt to be inspected. After the inspection is completed, the linear drive unit 262 drives the third transmission pulley 2333 to adjust its position in the vertical direction to loosen the transmission belt. The first rotary cylinder 2512 drives the first limit wheel 2511 to rotate, and the second rotary cylinder 2522 drives the second limit wheel 2521 to rotate and separate from the transmission belt respectively. The first unloading cylinder 2411 drives the unloading rod 2412, and the second unloading cylinder 2421 drives the unloading block 2422 to push out the inspected transmission belt. Good transmission belts are hung on the good product rack 11, and defective transmission belts are placed in the defective product box for subsequent collection.
