Description

Technical Field

[0001] This invention relates to the field of flat glass inspection technology, specifically to a flat glass defect detection device. Background Technology

[0002] During the production of flat glass, various defects such as bubbles, cracks, and scratches are inevitable. In particular, some special flat glass requires edge grinding, which can lead to defects such as chipping and corner breakage, affecting the appearance quality or functionality. Currently, flat glass defects are mainly monitored online by the naked eye. However, for tiny and deep defects that are difficult to detect with the naked eye, ultrasonic testing is required. Ultrasonic testing is a technique that uses ultrasound to non-destructively inspect the internal defects and scratches of materials or mechanical parts. It is widely used in machinery, metallurgy, and other industries. When using an ultrasonic flaw detector, if there is air between the ultrasonic probe and the workpiece being inspected, the ultrasound waves will be reflected and cannot enter the workpiece. In order for the ultrasound waves to be able to penetrate smoothly into the workpiece, a sound-transmitting coupling medium needs to be applied between the ultrasonic probe and the inspection surface of the workpiece to eliminate the air.

[0003] Flat glass is mostly custom-made and large in size, so the distance between the detection positions is long and the amount of coupling agent used is large. However, after the detection probe is completed, the coupling agent is cleaned up by the subsequent coupling agent cleaning machine, which causes waste and affects the economic benefits of enterprises.

[0004] Therefore, in order to solve the above problems, a defect detection device for flat glass is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a defect detection device for flat glass, which solves the problem mentioned in the background art that the flat glass in the prior art is mostly customized and large in size, so the distance between the detection positions is long and the amount of coupling agent used is large. After the detection probe is completed, the coupling agent is cleaned up by the subsequent coupling agent cleaning machine, which causes waste and affects the economic benefits of enterprises.

A coil spring is fixedly connected to the outer wall of the rotating shaft. The scraping structure is equipped with a conveying structure, which includes an inclined trough guide bucket. The inclined trough guide bucket is fixedly installed inside the scraping block. A second sprocket is movably installed inside the scraping block via a bearing. A rotating frame is fixedly connected to the second sprocket. A fourth spring is fixedly connected to the end of the rotating frame. A metal ball is fixedly connected to the end of the fourth spring.

[0007] Preferably, the bottom surfaces of both the first scraper and the second scraper are in contact with the bottom wall of the funnel-shaped groove, the second scraper abuts against the side wall of the funnel-shaped groove, and one end of the first spring is fixedly connected to the inner wall of the second scraper.

[0008] Preferably, the rectangular guide rod is slidably installed inside the fixed frame, the block is slidably installed on the inner wall of the rectangular guide rod, and one end of the pull rope is wound on the rope reel.

[0009] Preferably, the guide block is located inside the shallow and deep slide grooves and cooperates with the shallow and deep slide grooves, the middle slide groove and the deep slide groove, and one end of the second spring is fixedly connected to the rectangular guide rod.

[0010] Preferably, one end of the third spring is fixedly connected to the fixed frame, the roller is in contact with the top surface of the rectangular guide rod, and one end of the coil spring is fixedly connected to the movable rod.

[0011] Preferably, the depth of the deep groove is greater than the depth of the middle groove, both the middle groove and the deep groove are planar, the lower end depth of the deep groove is less than the left end depth of the shallow and deep grooves, the upper end depth of the middle groove is greater than the right end depth of the shallow and deep grooves, and the shallow and deep grooves are inclined surfaces.

[0012] Preferably, one output end of the motor is fixedly connected to the rope reel, the first sprocket is provided in two sets, the other set of motors is fixedly installed on the other output end of the motor, and one end of the chain is sleeved on the second sprocket.

[0013] Preferably, the left end of the inclined trough guide bucket is located to the left of the coupling agent application mechanism and the detection mechanism, the second sprocket and the rotating frame are both located on the lower side of the inclined trough guide bucket, and the metal ball cooperates with the inclined trough guide bucket.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The detection device of the present invention, by setting a scraper on the lower side of the housing, and cooperating with the movement of the first scraper and the second scraper, can scrape and collect the coupling agent in the detected area on the flat glass, and transport it to the undetected area through the conveying structure. The coupling agent can be used multiple times to reduce waste, keep the surface of the flat glass clean, and improve the economic benefits of the enterprise.

[0015] Equipped with a scraping structure, a driving structure, and a conveying structure, the motor, when started, drives the rope reel to rotate. As the reel rotates, it winds up the rope, which in turn pulls the connecting rod and rectangular guide rod to move inside the mounting frame. As the connecting rod moves, it causes the guide block to slide to the right within the deep and shallow grooves. Simultaneously, the rectangular guide rod slides within the fixed frame, which in turn causes the block to slide within the rectangular guide rod. Furthermore, the rollers roll on the rectangular guide rod, causing the coil spring to deform. This, combined with the movable rod and the third spring, allows the connecting rod and rectangular guide rod to move within the fixed frame. The inner linear movement, the connecting rod and the rectangular guide rod can pull the first scraper, so that the first scraper slides in the funnel-shaped groove. The two sets of second scrapers on the surface of the first scraper are in contact with the inner wall of the funnel-shaped groove and move in the funnel-shaped groove as the first scraper moves, and stretch the first spring, so that the first scraper and the second scraper move in the funnel-shaped groove. The left end of the funnel-shaped groove is then left open, so that the scraper can scoop the coupling agent into the funnel-shaped groove. When the guide block moves to the right end of the first spring, the guide block enters the upper end of the middle sliding groove under the action of the second spring. Then the motor reverses, driving the rope reel to rotate, which lengthens the pull rope. The pull rope releases the tension on the connecting rod and the rectangular guide rod. The roller reverses under the action of the coil spring, and the roller drives the rectangular guide rod and the connecting rod to move to the left. The guide block slides downward in the middle sliding groove, and the block slides to the left in the rectangular guide rod and upward in the fixed frame. This allows the connecting rod and the rectangular guide rod to move upward a certain distance inside the fixed frame, pushing the roller and the movable rod, stretching the third spring, and causing the first scraper and the second scraper at the left end to separate upward from the inner wall of the funnel-shaped groove. Furthermore, under the action of the second spring, the guide block will enter the upper end of the deep groove from the lower end of the middle groove and slide downward in the deep groove, causing the block to continue sliding to the left in the rectangular guide rod and downward in the fixed frame. When the guide block moves to the lower end of the deep groove, it will enter the left end of the deep and shallow grooves. At this time, the connecting rod and the rectangular guide rod will reset inside the fixed frame, and the first scraper and the second scraper will reset in the funnel-shaped groove. The first scraper and the second scraper will re-adhere to the inner wall of the funnel-shaped groove, which can prevent the coupling agent in the funnel-shaped groove from flowing out to the left. When the motor rotates again to drive the rope reel to wind up the rope, the coupling agent in the funnel-shaped groove can be scraped to the right with the cooperation of the first scraper and the second scraper, so that the coupling agent enters the inclined guide bucket through the right end of the funnel-shaped groove and flows to the left along the inner wall of the inclined guide bucket. When the motor and rope reel are running, they drive the first sprocket to rotate. The first sprocket then drives the second sprocket to rotate via a chain. The second sprocket drives the rotating frame to rotate, which in turn drives the fourth spring and metal ball to rotate in a circular motion. The metal ball impacts the bottom of the inclined chute guide, causing the chute guide to vibrate. This accelerates the flow of the coupling agent from right to left within the inclined chute guide, and it flows out through the left end of the chute guide, dripping onto areas of the flat glass that have not been coated with coupling agent and have not been tested. This improves the utilization rate of the coupling agent, reduces waste, enhances the company's economic efficiency, and ensures a good user experience. Attached Figure Description

A fourth spring 44 is fixedly connected to the end of the rotating frame 43. A metal ball 45 is fixedly connected to the end of the fourth spring 44. By setting the scraper block 21 on the lower side of the outer shell 1, and cooperating with the movement of the first scraper 23 and the second scraper 26, the coupling agent in the detected area on the flat glass can be scraped and collected, and then conveyed to the undetected area through the conveying structure 4. The coupling agent can be reused multiple times to reduce waste, keep the surface of the flat glass clean, and improve the economic benefits of the enterprise.

[0021] Furthermore, the bottom surfaces of the first scraper 23 and the second scraper 26 are both in contact with the bottom wall of the funnel-shaped groove 22, the second scraper 26 abuts against the side wall of the funnel-shaped groove 22, and one end of the first spring 25 is fixedly connected to the inner wall of the second scraper 26. The coupling agent in the funnel-shaped groove 22 can be scraped to the right into the inclined guide hopper 41 through the first scraper 23 and the second scraper 26. The first spring 25 provides power for the second scraper 26 to abut against the inner wall of the funnel-shaped groove 22.

[0022] Furthermore, the rectangular guide rod 28 is slidably installed inside the fixed frame 212, and the block 213 is slidably installed on the inner wall of the rectangular guide rod 28. One end of the pull rope 29 is wound around the rope reel 32. The block 213 allows the rectangular guide rod 28 to move up and down and left and right within the fixed frame 212, and the rectangular guide rod 28 is always perpendicular to the fixed frame 212 without deflection. The rotation of the rope reel 32 can rewind or lengthen the pull rope 29.

[0023] Furthermore, the guide block 210 is located inside the shallow and deep slide grooves 35 and cooperates with the shallow and deep slide grooves 35, the middle slide groove 36 and the deep slide groove 37. One end of the second spring 211 is fixedly connected to the rectangular guide rod 28. The guide block 210 can move unidirectionally in the shallow and deep slide grooves 35, the middle slide groove 36 and the deep slide groove 37. The second spring 211 provides power for the guide block 210 to abut against the inner wall of the shallow and deep slide grooves 35, the middle slide groove 36 and the deep slide groove 37.

[0024] Furthermore, one end of the third spring 215 is fixedly connected to the fixed frame 212, the roller 216 is in contact with the top surface of the rectangular guide rod 28, one end of the coil spring 217 is fixedly connected to the movable rod 214, the third spring 215 provides power for the movable rod 214 to reset on the fixed frame 212, so that the roller 216 can be tightly in contact with the rectangular guide rod 28, and the coil spring 217 provides power for the rectangular guide rod 28 to move to the left within the fixed frame 212.

[0025] Furthermore, the depth of the deep groove 37 is greater than the depth of the middle groove 36. Both the middle groove 36 and the deep groove 37 are planar. The lower end depth of the deep groove 37 is less than the left end depth of the shallow-deep groove 35. The upper end depth of the middle groove 36 is greater than the right end depth of the shallow-deep groove 35. The shallow-deep groove 35 is an inclined surface. The guide block 210 can move unidirectionally in the shallow-deep groove 35, the middle groove 36 and the deep groove 37, so that the first scraper 23 and the second scraper 26 can move in a triangular direction in the funnel-shaped groove 22, so that the coupling agent can enter the funnel-shaped groove 22 and be scraped to the right into the inclined groove guide bucket 41 under the action of the first scraper 23 and the second scraper 26.

[0026] Furthermore, one output end of the motor 38 is fixedly connected to the rope reel 32, the first sprocket 33 is provided with two sets, the other set of motors 38 is fixedly installed on the other output end of the motor 38, one end of the chain 34 is sleeved on the second sprocket 42, the motor 38 provides power for the rotation of the rope reel 32, and the transmission of the chain 34 can drive the second sprocket 42 to rotate.

[0027] Furthermore, the left end of the inclined trough guide 41 is located to the left of the coupling agent application mechanism 12 and the detection mechanism 13. The second sprocket 42 and the rotating frame 43 are both located on the lower side of the inclined trough guide 41. The metal ball 45 cooperates with the inclined trough guide 41. When the metal ball 45 rotates, it can hit the bottom surface of the inclined trough guide 41, causing the inclined trough guide 41 to vibrate and accelerate the flow of coupling agent in the inclined trough guide 41.

[0028] Working principle: During use, the moving mechanism 11 drives the outer shell 1 to move, and the coupling agent can be applied to the predetermined position by the coupling agent application mechanism 12. The detection mechanism 13 can detect the position on the flat glass where the coupling agent is applied. As the outer casing 1 moves, the detection mechanism 13 moves away from the detected position, and the scraper 21 contacts the coupling agent at the detected position, starting the motor 38. The motor 38 drives the rope reel 32 to rotate. When the rope reel 32 rotates, it can wind up the pull rope 29, and pull the connecting rod 27 and the rectangular guide rod 28 to move inside the mounting frame 31. When the connecting rod 27 moves, it drives the guide block 210 to slide to the right in the deep and shallow slide groove 35. At the same time, the rectangular guide rod 28 slides in the fixed frame 212. The fixed frame 212 drives the block 213 to slide in the rectangular guide rod 28, and the roller 216 rolls on the rectangular guide rod 28, pulling the coil spring 217 to deform. With the cooperation of the movable rod 214 and the third spring 215, the connecting rod 210 can move to the right. The connecting rod 27 and the rectangular guide rod 28 move linearly within the fixed frame 212. The connecting rod 27 and the rectangular guide rod 28 can pull the first scraper 23, causing the first scraper 23 to slide within the funnel-shaped groove 22. The two sets of second scrapers 26 on the surface of the first scraper 23 are attached to the inner wall of the funnel-shaped groove 22 and move within the funnel-shaped groove 22 as the first scraper 23 moves, stretching the first spring 25. This causes the first scraper 23 and the second scraper 26 to move within the funnel-shaped groove 22, leaving the left end of the funnel-shaped groove 22 empty, making it easier for the scraper block 21 to scoop the coupling agent into the funnel-shaped groove 22. When the guide block 210 moves to the right end of the first spring 25, the guide block 210 enters the upper end of the middle sliding groove 36 under the action of the second spring 211. Then, the motor 38 reverses, driving the rope disc 32 to rotate, which can lengthen the pull rope 29. The pull rope 29 releases the tension on the connecting rod 27 and the rectangular guide rod 28. The roller 216 reverses under the action of the coil spring 217. The roller 216 drives the rectangular guide rod 28 and the connecting rod 27 to move to the left. The guide block 210 slides downward in the middle sliding groove 36, and the block 213 slides to the left in the rectangular guide rod 28 and slides upward in the fixed frame 212. This allows the connecting rod 27 and the rectangular guide rod 28 to move upward a certain distance inside the fixed frame 212, pushing the roller 216 and the movable rod 214, stretching the third spring 215, and driving the first scraper 23 and the second scraper 26 at the left end to separate upward from the inner wall of the funnel-shaped groove 22. Furthermore, under the action of the second spring 211, the guide block 210 will enter from the lower end of the middle slide groove 36 to the upper end of the deep slide groove 37, and slide downward within the deep slide groove 37, causing the cube 213 to continue sliding to the left within the rectangular guide rod 28 and downward within the fixing frame 212. When the guide block 210 moves to the lower end of the deep slide groove 37, it will enter the left end of the deep and shallow slide groove 35. At this time, the connecting rod 27 and the rectangular guide rod 28 will reset inside the fixing frame 212, and the first scraper 23 and the second scraper 26 will... The first scraper 23 and the second scraper 26 re-adhere to the inner wall of the funnel-shaped groove 22 after resetting within the funnel-shaped groove 22, which can prevent the coupling agent in the funnel-shaped groove 22 from flowing out to the left. When the motor 38 rotates again to drive the rope disc 32 to wind up the rope 29, the coupling agent in the funnel-shaped groove 22 can be scraped to the right with the cooperation of the first scraper 23 and the second scraper 26, so that the coupling agent enters the inclined guide hopper 41 through the right end of the funnel-shaped groove 22 and flows to the left along the inner wall of the inclined guide hopper 41. When the motor 38 and the rope disc 32 are running, they will drive the first sprocket 33 to rotate. The first sprocket 33 will then drive the second sprocket 42 to rotate via the chain 34. The second sprocket 42 will drive the rotating frame 43 to rotate. The rotating frame 43 will drive the fourth spring 44 and the metal ball 45 to rotate in a circular motion. The metal ball 45 will hit the bottom surface of the inclined trough guide 41, causing the inclined trough guide 41 to vibrate. This will accelerate the flow of the coupling agent from right to left within the inclined trough guide 41 and allow it to flow out through the left end of the inclined trough guide 41. It can drip onto the areas of the flat glass that have not been coated with coupling agent and have not been tested, thereby improving the utilization rate of the coupling agent, reducing waste, improving the economic efficiency of the enterprise, and ensuring a good user experience.
