Abstract
Description
Technical Field
[0001] The invention relates to the technical field of detonating cord detection, in particular to an automatic fault detection system for a detonating cord production line. Background Art
[0002] Detonating cord is a key material in blasting operations, and quality control in its production process is crucial. In the production line of detonating cord, fault detection is an important link to ensure product quality and safety. However, the existing fault detection system of detonating cord production line has some obvious limitations, especially in the process of conveying and detecting detonating cord.
[0003] First, since the detonating cord is usually transported continuously and at high speed, and part of it is located under the conveyor belt, it is difficult to fully cover it with conventional technical means such as infrared detection. Infrared detection mainly relies on the absorption, reflection or radiation characteristics of infrared light by objects to detect, but when part of the detonating cord is located below, due to the limitation of occlusion and reflection angle, the infrared detector often cannot effectively capture the signal of this part of the detonating cord, resulting in a detection blind spot. This blind spot not only reduces the accuracy of detection, but also may cause some potential quality problems to be missed.
[0004] Secondly, the existing detection system can usually only detect a specific surface of the detonating cord and cannot achieve 360-degree all-round detection. Since the detonating cord may be affected by many factors during the production process, such as temperature, pressure, friction, etc., these factors may have different effects on different parts of the detonating cord. Therefore, it is difficult to fully reflect its overall quality status by only testing a specific surface of the detonating cord. In addition, if the detonating cord has surface defects or internal damage, and these damages happen to be located in the blind area or undetected surface of the detection system, then these defects may be missed, thereby posing a safety hazard to subsequent use.

[0015] Beneficial effects of the automatic fault detection system for a detonating cord production line of the present invention:
[0016] 1. Through the multiple fixed rods and telescopic rods inside the mounting platform, the system can adaptively compress detonating cords of different sizes to ensure that the detonating cord remains straight during transportation. The speed regulating motor drives the pressing wheel to rotate, driving the detonating cord to move, and at the same time cooperates with the detection heads evenly distributed on the inner wall of the mounting ring to achieve all-round and no-dead-angle detection of the detonating cord, effectively avoiding the detection blind spot problem in traditional methods such as infrared detection, and improving the accuracy and comprehensiveness of detection.
[0017] 2. The fixture in the conveying mechanism clamps the detonating cord through the clamp controlled by the telescopic rod 2, and is driven by the transmission component to move. The detonating cord is straightened and stretched through the speed difference, simulating the tension in actual use and effectively testing the tensile performance of the detonating cord. The cutter component cuts off the detonating cord at the specified length, ensuring that each section of the detonating cord has been tested for tensile strength, thereby ensuring the stability of product quality.
[0018] 3. The reeling mechanism uses the friction between the pressure plate and the collar to drive the detonating cord to move, and fixes the detonating cord through the cooperation of the pressure groove and the clamping plate, so as to achieve rapid reeling of the detonating cord. The push assembly not only ensures the uniformity of reeling through the synergistic effect of the sliding rod, the first stopper rod, the second stopper rod and other components, but also pushes the detonating cord out through the top plate after reeling is completed, which is convenient for the robot to take the material, and improves the production efficiency and automation level.

[0034] The reel assembly 34 is rotatably connected to the support plate 32 on the top of the support plate 31, and a drive motor 36 is arranged on the outer wall of the support frame 31 near the reel assembly 34. The output end of the drive motor 36 passes through the support frame 31 and is connected to the reel assembly 34. The reel assembly 34 includes a rotating shaft 341 rotatably connected to the inner wall of the support plate 32, and a slide groove 3411 is arranged on the outer surface of the rotating shaft 341. A pushing assembly 343 is arranged on one end of the rotating shaft 341 near the driving motor 36, and a sliding rod 344 is connected to the output end of the pushing assembly 343. The sliding rod 344 is slidably connected to the inner wall of the rotating shaft 341, and the outer surface of the sliding rod 344 is rotatably connected to the inner wall of the rotating shaft 341. A second slide groove 3441 is provided at a position corresponding to the first slide groove 3411 on the surface, a first stopper 3442 and a second stopper 3446 are provided inside the second slide groove 3441, a third spring 3443 and a push plate 3445 are provided inside the slide rod 344, the push plate 3445 is slidably connected with the slide rod 344 and the inner wall of the second slide groove 3441, one end of the first stopper 3442 and the second stopper 3446 passes through the first slide groove 3411 and extends to the outside of the rotating shaft 341, a top block 1 342 is slidably connected inside the end of the slide rod 344 away from the first stopper 3442, a second spring 3421 connected to the inner wall of the rotating shaft 341 is provided at the end of the top block 1 342 away from the slide rod 344, and the hardness of the second spring 3421 is greater than that of the third spring 3443;
[0035] When the slide bar 344 is pushed by the pushing assembly 343, the second blocking rod 3446 will gradually approach the top block 1 342 for docking. After docking, the top block 1 342 will push the end of the second blocking rod 3446 located inside the slide bar 344, so that the part of the second blocking rod 3446 located outside the rotating shaft 341 will flip over and be retracted into the sliding groove 1 3411.
[0036] By adopting the above technical solution, the detonating cord is fully checked by installing the detection head 19 in the ring 18. While the detonating cord is being rolled up, the pushing component 343 will slowly push the slide bar 344, thereby driving the blocking rod 1 3442, the blocking rod 2 3446, the ring 351, etc. to move slowly, so as to facilitate the even rolling of the detonating cord onto the surface of the ring 351. When the winding is completed, the pushing component 343 will drive the ring 351 to approach the tail end of the rotating shaft 341 through the sliding rod 344. After the sliding rod 344 moves a certain distance, it will drive the second blocking rod 3446 to contact the top block 1 342. The hardness of the spring 2 3421 is greater than the hardness of the spring 3443, so the spring 3443 will be squeezed and compressed first. Therefore, the position of the top block 1 342 is basically stationary in the early stage, and the second blocking rod 3446 is pushed to flip into the slide groove 1 3411. Then the detonating cord is removed from the ring 351 by the manipulator for packaging, and then the pushing component 343 pulls the sliding rod 344 to reset. When the blocking rod 2 3446 is away from the top block 1 342, the spring 3443 will be reset through the push plate 3445.
[0037] The conveying mechanism 2 also includes a fixed seat 21, a conveyor belt 24 is arranged on the top of the fixed seat 21, mounting grooves 211 are symmetrically provided on both sides of the fixed seat 21, a fixture and a transmission assembly 22 are arranged inside the mounting groove 211, the fixture includes a slider 23 which is slidably connected to the inner wall of the mounting groove 211, a telescopic rod 231 is arranged inside the end of the slider 23 close to the conveyor belt 24, a clamp 232 is fixedly connected to the output end of the telescopic rod 231, a docking port 25 is opened at the end of the fixed seat 21 close to the mounting platform 11, a cutter assembly 26 is arranged at a position close to the docking port 25 in the fixed seat 21, a baffle 27 is arranged at a position close to the conveyor belt 24 at the end of the fixed seat 21 away from the mounting platform 11, a limiting opening 271 is provided on the outer wall of the baffle 27, the bottom of the clamp 232 of the clamp is slidably connected to the conveyor belt 24, and the transmission assembly 22 is connected to the clamp to drive the clamp to move along the conveyor belt 24.
[0038] By adopting the above technical solution, after the detonating cord passes through the detection mechanism 1, it enters the fixed seat 21 through the docking interface 25 and falls back to the conveyor belt 24. The telescopic rod 231 pushes the clamp 232 to clamp one end of the detonating cord, and the transmission component 22 moves with the clamp, and the speed exceeds the pressure wheel 16, forming a speed difference to straighten the detonating cord. Adjust the speed of the transmission component 22 to control the tension, measure the tensile resistance, ensure the quality stability, and the tension is less than 50KG. When it reaches the specified length, the cutter component 26 cuts the detonating cord, the clamp is loosened, and the transmission component 22 is reset. The cut detonating cord falls to the winding mechanism 3 through the limit opening 271 of the arc baffle 27.
[0039] There are two groups of fixed rods 12 and they are symmetrically distributed in the circular cavity surrounded by the mounting platform 11. There are three fixed rods 12 in each group and they are evenly distributed along the inner wall of the circumference of the mounting platform 11. A telescopic rod 13 is arranged inside the fixed rod 12. A sleeve 14 is fixedly connected to the output end of the telescopic rod 13. The sleeve 14 is slidably connected to the inner wall of the fixed rod 12. A mounting opening is provided on the side of the sleeve 14 facing the outside of the fixed rod 12. A wheel seat 15 is slidably connected inside the mounting opening. A pressure wheel 16 is rotatably connected inside the wheel seat 15. A speed regulating motor 17 is arranged on the outer wall of the wheel seat 15 near the pressure wheel 16. The output end of the speed regulating motor 17 passes through the wheel seat 15 and is fixedly connected to the pressure wheel 16.
[0040] By adopting the above technical solution, the detonating cord reaches the detection mechanism 1, passes through the center of the mounting platform 11, and is squeezed by the pressure wheel 16. The telescopic rod 13 is adjusted to press the multi-size detonating cords, and the spring 151 is prevented from being damaged. The speed regulating motor 17 drives the pressure wheel 16 to rotate and straighten the cord.
[0041] The outer surface of the rotating shaft 341 is slidably connected with a clamping assembly 35, and the clamping assembly 35 includes a collar 351 slidably connected to the outer wall of the rotating shaft 341, one end of the collar 351 is fixedly connected to the stop rod 1 3442, and a limiting groove 352 is provided on the outer surface of the collar 351 at one end away from the stop rod 1 3442, and a sliding opening 354 is provided on the inner wall of the end of the collar 351 away from the stop rod 1 3442, and the sliding opening 354 is arranged at a position close to the limiting groove 352. A docking interface 2 353 is provided at one end of the ring 351 away from the blocking rod 1 3442, a clamping plate 355 is slidably connected inside the limiting groove 352, a spring 4 356 connected to the inner wall of the limiting groove 352 is provided on one side of the clamping plate 355, a top plate 357 is slidably connected to the inner wall of the sliding mouth 354, and the top plate 357 is provided with a docking surface 3572 which is an inclined surface, and a top block 2 358 is provided at the position of the outer wall of the rotating shaft 341 corresponding to the docking interface 2 353.
[0042] By adopting the above technical solution, the detonating cord is pressed into the limit groove 352 and fixed between the clamping plate 355. After winding, the pushing assembly 343 pushes the sleeve ring 351 close to the end of the rotating shaft 341 through the sliding rod 344. After the sliding rod 344 moves, the second top block 358 enters the second docking interface 353, squeezes the docking surface 3572 to move the top plate 357, and pushes out the detonating cord between the clamping plates 355.
[0043] A fixing seat 2 331 is provided at the top of the support frame 31 below the rotating shaft 341, and a pressure plate 33 is hinged on the top of the fixing seat 2 331. A connecting seat 333 is provided on the outer wall of the pressure plate 33 near the bottom, and a telescopic rod 334 is hinged inside the connecting seat 333. One end of the telescopic rod 334 is hinged to the support frame 31, and a pressing groove 332 is provided on the side of the pressure plate 33 close to the rotating shaft 341. The pressing groove 332 is slidably connected to the outer wall of the ring 351, and the position of the limiting groove 352 corresponds to the pressing groove 332. Only the lower half of the side of the pressure plate 33 with the limiting groove 352 is close to the outer wall of the ring 351.
[0044] By adopting the above technical solution, the pressure groove 332 formed on the outer wall of the pressure plate 33 in the winding mechanism 3 is aligned with the limiting opening 271 of the baffle 27. When the detonating cord falls through the limiting opening 271, it falls between the pressure groove 332 and the ring 351. The rotating shaft 341 drives the ring 351 to rotate, and the friction force of the ring 351 drives the detonating cord to move. When the detonating cord moves to the lower half of the pressure groove 332, the pressure increases, and the detonating cord is pressed into the limiting groove 352 between the clamping plates 355 for fixation.
[0045] Working principle of the present invention:
[0046] When in use, the detonating cord will first arrive at the detection mechanism 1, pass through the center position inside the mounting platform 11, and be squeezed by the pressure wheel 16. The telescopic rod 13 is used to control the position of the pressure wheel 16, so that the pressure wheel 16 can compress detonating cords of various sizes. The spring 151 therein is used to prevent the pushing force of the telescopic rod 13 from being too large, which may cause damage to the detonating cord. The speed regulating motor 17 is used to drive the pressure wheel 16 to rotate and move the detonating cord. When the pressure wheel 16 drives the detonating cord to move, it will straighten it, which can facilitate a comprehensive inspection of the multiple detection heads 19 inside the mounting ring 18 located at the center position inside the mounting platform 11.
[0047] The detonating cord passes through the inspection of the detection mechanism 1, and then enters the interior of the fixing seat 21 through the docking interface 25. After entering the interior of the fixing seat 21, the detonating cord falls back onto the conveyor belt 24, and then the telescopic rod 231 in the clamp will push the clamp 232 to clamp one end of the detonating cord, and then the transmission component 22 drives the clamp to move. The speed at which the transmission component 22 drives the clamp to move is greater than the speed at which the pressure wheel 16 drives the detonating cord to move, so a speed difference is formed between the two, so that the detonating cord located in the conveying mechanism 2 will be straightened and tightened. The tension on the detonating cord is adjusted by controlling the speed of the transmission component 22, so that the tensile strength of the detonating cord can be tested, and each section of the detonating cord can be tested to ensure the quality stability of the detonating cord. The tensile strength of the tensile strength test should be less than the 50KG tensile strength in the detonating cord quality test.
[0048] When the clamp pulls the detonating cord to the specified length, the cutter assembly 26 at the interface 25 will cut it off, and then the clamp will be released, and the transmission assembly 22 will drive the clamp to reset. The cut detonating cord will be pulled to the baffle 27 along the conveyor belt 24. The baffle 27 is an arc-shaped plate with a limited opening 271 in the middle. The guide plate that has arrived here can be centered so that it passes through the limited opening 271 and then falls to the winding mechanism 3.
[0049] The pressing groove 332 formed on the outer wall of the pressing plate 33 in the winding mechanism 3 is aligned with the limiting opening 271 of the baffle plate 27. When the detonating cord falls through the limiting opening 271, it will fall between the pressing groove 332 and the ring 351. The rotating shaft 341 drives the ring 351 to rotate, and the friction force of the ring 351 drives the detonating cord to move. When the detonating cord moves to the lower half of the pressing groove 332, the pressure increases, which will press the detonating cord into the clamping plates 355 in the limiting groove 352 for fixation. Then the telescopic rod three 334 pulls the pressing plate 33 to flip away from the rotating shaft 341. After one end of the detonating cord is fixed, the rotating shaft 341 rotates faster to reel in the detonating cord. While reeling in, the pushing assembly 343 will slowly push the sliding rod 344, thereby driving the baffle rod 1 3442, the baffle rod 2 3446, the ring 351, etc. to move slowly, so as to facilitate the even reeling of the detonating cord onto the surface of the ring 351.
[0050] When the winding is completed, the pushing component 343 will drive the ring 351 to approach the tail end of the rotating shaft 341 through the sliding rod 344. After the sliding rod 344 moves a certain distance, it will drive the second blocking rod 3446 to contact the top block 1 342. The hardness of the spring 2 3421 is greater than the hardness of the spring 3443, so the spring 3443 will be squeezed and compressed first. Therefore, the position of the top block 1 342 is basically stationary in the early stage, and the second blocking rod 3446 is pushed to flip into the sliding groove 1 3411. When the ring 351 moves When the top block 358 moves close to the tail end of the rotating shaft 341, it will dock with the docking interface 353. The top block 358 enters the docking interface 353 and moves the top plate 357 by squeezing the docking surface 3572, thereby ejecting the detonating cord between the clamping plates 355. The detonating cord can then be removed from the ring 351 by a manipulator and packaged. The pushing assembly 343 then pulls the sliding rod 344 to reset. When the blocking rod 3446 is away from the top block 342, the spring 3443 will reset through the pushing plate 3445.
[0051] The fixed rod 12, telescopic rod 13, control sleeve 14 and pressure wheel 16 in the mounting platform 11 can adaptively press detonating cords of different sizes to keep them straight. The speed regulating motor 17 drives the pressure wheel 16 to rotate, and the detection head 19 in the mounting ring 18 can detect the detonating cord in all directions, avoid blind spots, and improve accuracy. The clamp chuck 232 of the conveying mechanism 2 clamps the detonating cord, and the transmission component 22 moves, and the speed difference straightens and stretches to measure the tensile strength. The cutter component 26 cuts the detonating cord at the specified length, ensuring that each section of the detonating cord has been tested for tensile strength, thereby ensuring the stability of product quality. The pressure plate 33 and the sleeve ring 351 of the winding mechanism 3 rub the detonating cord, and the pressing groove 332 and the clamping plate 355 are fixed for fast winding. The pushing component 343 cooperates with the components to ensure uniform winding, and the top plate 357 pushes out the detonating cord for material removal, which improves efficiency and automation. The system is compact and reasonable, reducing land cost. The operation is simple, and the control component performs multiple tests on the detonating cord and then automatically winds it up.
