Description
Technical Field
[0001] This invention belongs to the field of sealing strip manufacturing technology, specifically a sealing strip defect identification and rejection device based on intelligent detection. Background Technology
[0002] A sealing strip is a functional component used to seal gaps and isolate media. It primarily fills the gap between two parts through the elastic deformation of the material, serving functions such as sealing, shock absorption, waterproofing, sound insulation, heat insulation, and dust prevention. During the manufacturing process, sealing strips are prone to defects such as pinholes and scratches. To prevent defective sealing strips from entering subsequent use, it is necessary to inspect the surface for defects and reject any defective strips.
[0003] In existing technologies, the detection of surface defects in batches of sealing strips typically relies on vision inspection conveyor lines. During operation, the sealing strips are laid flat on the surface of the conveyor belt and move with the conveyor belt past the vision inspection station to obtain surface images. Subsequently, image analysis technology is used to determine whether there are defects on the surface of the sealing strips.
[0004] However, when a batch of sealing strips moves on the conveyor belt, they are prone to stacking or crossing. Stacked sealing strips can completely or partially cover the surface of the sealing strips located below, causing the visual inspection equipment to be unable to obtain a complete and continuous surface image, creating blind spots in the inspection and increasing the risk of false detection and missed detection. Summary of the Invention

[0023] The beneficial effects of this invention are as follows:
[0024] 1. The sealing strip defect identification and rejection device based on intelligent detection described in this invention utilizes a sealing strip sorting mechanism to organize multiple sealing strips that were originally stacked randomly into a linear arrangement, and then move them sequentially to a vision inspection device for inspection. This avoids the situation where, during batch inspection of sealing strips, the sealing strips stack or cross on the conveyor line, causing the surface of the lower layer of sealing strips to be completely or partially obscured. This prevents the vision inspection equipment from obtaining a complete and continuous surface image, creating blind spots and leading to false or missed detections, thus improving the accuracy of the inspection results.
[0025] 2. The sealing strip defect identification and rejection device based on intelligent detection described in this invention utilizes an active orientation component. Under the friction of multiple friction discs, it can actively deflect sealing strips with incorrect orientation and, under the push of gravity and subsequent sealing strips, correct their orientation. This significantly reduces the randomness of changing the sealing strip angle through the friction of the conveyor belt and the pushing force of the rectangular pushing surface, making it easier to adjust the sealing strip to the correct posture and ensuring the stability and continuity of subsequent detection work.
[0026] 3. The sealing strip defect identification and rejection device based on intelligent detection described in this invention utilizes a booster component. Whenever the rectangular pushing surface is at its lowest point, a toggle block continuously pushes the sealing strip stuck on the friction disc, allowing the sealing strip to slide smoothly onto the rectangular pushing surface, thus ensuring smooth delivery of the sealing strip. Furthermore, because the toggle block moves along a rectangular trajectory, it does not obstruct or push back subsequent sealing strips. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0044] Example 1:
[0045] Please refer to Figures 1-14This invention provides a technical solution: a sealing strip defect identification and rejection device based on intelligent detection, including a vision inspection device 3 and a frame 8. The frame 8 is provided with a second conveyor belt 11. The vision inspection device 3 is fixedly installed on one side of the frame 8.

The image acquisition unit is used to acquire the surface image of the sealing strip conveyed by the second conveyor belt 11 and upload the acquired image to the image processing unit for analysis, including a sealing strip material handling mechanism.
[0046] The sealing strip feeding mechanism includes a feeding frame 1, a first feeding plate 24, and a second feeding plate 25. The upper edge of the feeding frame 1 is flush with the upper edge of the frame 8. A feeding plate 22 for placing sealing strips is slidably connected to the inner wall of the feeding frame 1.

The piston end of the cylinder 736 is fixedly connected to one end of the bottom of the material plate 1 24.

[0052] like Figure 7 As shown, it includes a transfer mechanism for rejecting defective sealing strips;
[0053] The transfer mechanism includes a support frame 4, which is located at the end of the conveyor belt 11 in the conveying direction. A slider 13 is slidably connected to one side surface of the support frame 4. A cylinder 14 is fixedly connected to one side of the slider 13. A transverse plate 15 is fixedly connected to the piston end of the cylinder 14. A transverse plate 17 is slidably connected to one side end face of the transverse plate 15. A turntable 19 is rotatably connected to one end of the transverse plate 17. A finger cylinder 20 is fixedly connected to one side end face of the turntable 19.
[0054] like Figure 7 As shown, a cylinder 12 is fixedly connected to one side of the top of the support frame 4. The piston end of the cylinder 12 is fixedly connected to one side of the slider 13. A cylinder 16 is fixedly connected to one end of the transverse plate 15. The piston end of the cylinder 16 is fixedly connected to one end of the transverse plate 17. A motor 18 is fixedly connected to one side of the transverse plate 17. The output end of the motor 18 is fixedly connected to one end of the turntable 19.
[0055] like Figure 5 and Figure 10 As shown, the material handling frame 1 is equipped with a push-down assembly for removing the sealing strips that are erected or overlapped on the rectangular push surface;
[0056] The push-down assembly includes a push plate 10 that slides through one side of the material handling frame 1. Two guide rods 35 are fixedly connected to one side surface of the push plate 10. The guide rods 35 slide through the material handling frame 1. A cylinder 34 is fixedly connected to one side of the outer wall of the material handling frame 1. The piston end of the cylinder 34 is fixedly connected to one side of the push plate 10.
[0057] Specifically, in existing technologies, the detection of surface defects in batches of sealing strips typically relies on vision inspection conveyor lines. During operation, the sealing strips are laid flat on the surface of the conveyor belt and move with the conveyor belt past the vision inspection station to obtain surface images. Subsequently, image analysis technology is used to determine whether there are defects on the surface of the sealing strips.
[0058] However, when a batch of sealing strips moves on the conveyor belt, they are prone to stacking or crossing. Stacked sealing strips can completely or partially cover the surface of the sealing strips located below, causing the visual inspection equipment to be unable to obtain a complete and continuous surface image, creating blind spots in the inspection and increasing the risk of false detection and missed detection.
[0059] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:
[0060] This solution is only applicable to defect detection of solid rigid PVC sealing strips of the same specification in the same batch. These sealing strips have a "hard plastic" texture, poor flexibility but can provide strong rigid support. Furthermore, this solution is suitable for detecting solid rigid PVC sealing strips with square or circular cross-sections.
[0061] Furthermore, since the methods for testing solid rigid PVC sealing strips with square or circular cross-sections are essentially the same, the following explanation will only use sealing strips with circular cross-sections as an example.
[0062] First, adjust the sealing strip according to its specifications. Based on the diameter of the sealing strip, use cylinder 7 (36) to move material plate 24, causing its top to slide relative to the top of material plate 25. This adjusts the width of the rectangular pushing surface to match the diameter of the sealing strip. Next, use cylinder 2 (9) to move the placement plate 22, bringing its edge near the inner side of the material handling frame 1 into contact with the surface of material plate 24. Then, use cylinder 1 (5) to move the partition plate 7 laterally, adjusting the distance between the partition plate 7 and the edge of the frame 8, ensuring this edge is closer to the material handling frame 1 and that this distance matches the diameter of the sealing strip.
[0063] After the above adjustments are completed, place the multiple sealing strips to be tested on the surface of the conveyor belt 2 on the material placement plate 22, or connect the material placement plate 22 to the conveyor line of the previous process of the sealing strip.
[0064] After the sealing strip moves onto the conveyor belt 2, it moves towards the inside of the material handling frame 1 under the action of the conveyor belt 2, and gradually approaches the rectangular pushing surface formed by the material plate 24 and the material plate 25. At the same time, the material plate 25 is driven to move up and down reciprocally by the screw guide module 33, which can change the height of the rectangular pushing surface.
[0065] When the rectangular pusher surface is at its lowest point, it aligns with the upper surface of the placement plate 22; when it is at its highest point, it aligns with the upper edges of the material handling frame 1 and the frame 8. Therefore, when the rectangular pusher surface is at its lowest point, part of the sealing strip will move onto the rectangular pusher surface, and when the rectangular pusher surface rises, it will lift the sealing strip. Furthermore, since the width of the rectangular pusher surface is the same as the diameter of the sealing strip, the sealing strip can only be stably placed on the rectangular pusher surface and rise along the inner wall of the material handling frame 1 when the length direction of the sealing strip is parallel to the length direction of the rectangular pusher surface. Conversely, if the sealing strip is placed on the rectangular pusher surface in other postures, it will fall back to the placement plate 22 during the rise of the rectangular pusher surface because its center of gravity is not on the rectangular pusher surface. This is the first screening of the sealing strip's orientation; only sealing strips whose length direction is parallel to the length direction of the rectangular pusher surface can rise stably.
[0066] However, when multiple sealing strips parallel to the length direction of the rectangular push surface overlap on the rectangular push surface, the multiple sealing strips will also rise steadily with the rectangular push surface. Therefore, during the rising process of the rectangular push surface, when the straight-line distance between the rectangular push surface and the lower edge of the push plate 10 is equal to the diameter of the sealing strip, the rectangular push surface stops rising, and the cylinder six 34 drives the push plate 10 to move laterally, which can push the overlapping sealing strips off through the push plate 10, leaving only the bottom layer of sealing strips on the rectangular push surface. This is the second screening of the sealing strips. At this time, the multiple sealing strips still on the rectangular push surface are arranged linearly, so the push plate 10 resets, and the rectangular push surface continues to rise. When the rectangular push surface reaches the upper edge of the material handling frame 1, the sealing strips on the rectangular push surface will fall onto the conveyor belt two 11 due to the loss of the obstruction of the inner wall of the material handling frame 1, and move towards the vision inspection device 3 with the conveyor belt two 11. Furthermore, since the distance between the partition 7 and one edge of the frame 8 is equal to the diameter of the sealing strip, the multiple sealing strips on the conveyor belt 11 will still maintain a linear arrangement and will not be parallel or intersecting.
[0067] When a sealing strip reaches the image acquisition unit of the vision inspection device 3 and the end of the sealing strip passes the end of the conveyor belt 11, the conveyor belt 11 stops running. At this time, the position of the finger cylinder 20 in the x, y, and z axes can be adjusted by the movement of the slider 13 driven by the cylinder 3 12, the movement of the transverse plate 15 driven by the cylinder 4 14, and the movement of the transverse plate 17 driven by the cylinder 5 16, so that the clamping end of the finger cylinder 20 is aligned with the end of the sealing strip and the end of the sealing strip is clamped by the clamping end. At this time, the finger cylinder 20 can rotate the sealing strip by the rotation of the turntable 19 driven by the motor 18.
[0068] Simultaneously, the image acquisition unit, while continuously rotating, captures images of various areas of the sealing strip and uploads them to the image processing unit for analysis, thereby determining whether defects exist on the surface of the sealing strip. This detection process utilizes existing intelligent vision inspection technology and will not be elaborated upon further here. Furthermore, two containers for collecting the sealing strips can be placed at the end of conveyor belt 11. After inspection, the sealing strips can be removed from conveyor belt 11 using finger cylinders 20 and placed into different containers based on the inspection results, thus achieving the removal of defective sealing strips.
[0069] Then, repeating the above operation, the sealing strips in the feeding frame 1 will continuously adjust their posture due to the friction of the conveyor belt 2 and the pushing force of the rectangular pushing surface until they can be smoothly placed on the rectangular pushing surface. This causes the originally disordered stacked sealing strips to be arranged linearly and moved sequentially to the vision inspection device 3 for inspection. This avoids the situation where, during batch inspection of sealing strips, the sealing strips are stacked or crossed on the conveyor line, causing the surface of the lower layer of sealing strips to be completely or partially obscured. The vision inspection equipment cannot obtain a complete and continuous surface image, resulting in blind spots and thus false or missed detections, which helps to improve the accuracy of the inspection results.
[0070] Example 2:
[0071] In the above embodiment, although the sealing strip in the feeding frame 1 can continuously adjust its posture by being subjected to the friction of the conveyor belt 2 and the pushing force of the rectangular pushing surface until it can be successfully placed on the rectangular pushing surface, this way of changing posture is highly random, and it is easy for some sealing strips to be unable to adjust to the correct posture, which will affect the subsequent normal inspection.
[0072] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:
[0073] like Figure 6 , Figure 8 , Figure 9 As shown, the material feeding plate 22 is equipped with an active adjustment component;
[0074] The active adjustment component includes multiple friction discs 26, the upper surface of which is provided with anti-slip texture. The multiple friction discs 26 are arranged horizontally and rotatably mounted on the top of the material plate 22 near the material plate 24. A worm wheel 30 is fixedly connected to the bottom of the friction discs 26. Worms 29 are rotatably connected to both ends of the bottom of the material plate 22. Multiple worm teeth are intermittently provided on the worm 29, and each worm tooth meshes with a worm wheel 30. A motor 32 is fixedly connected to one side of the bottom of the material plate 22, and the output end of the motor 32 is fixedly connected to one end of the worm 29.
[0075] Specifically, whenever the rectangular push surface rises, the sealing strips that subsequently slide towards the rectangular push surface are blocked by one side surface of the material plate 24. Furthermore, the multiple sealing strips blocked in this area will randomly come into contact with each of the friction discs 26. At this time, the motor 32 drives the worm gear 29 to rotate, which, under the transmission of the worm wheel 30, causes multiple friction discs 26 to rotate simultaneously by a certain angle. The sealing strips in contact with the friction discs 26 will be subjected to a rotational force. If the length direction of the sealing strip subjected to the rotational force is parallel to the length direction of the rectangular push surface, and the sealing strip is in contact with the surface of the material plate 24, then even if it is subjected to friction from the friction discs 26, it will not easily deflect due to the obstruction of the material plate 24 and will maintain its original state.
[0076] Conversely, if the length direction of the sealing strip in contact with the material plate 24 is not parallel to the length direction of the rectangular push surface, then only one end of the sealing strip will be in contact with the material plate 24. In this case, the sealing strip will be subject to friction from the friction disc 26, making it prone to deflection and changing its angle. After changing its angle, the sealing strip will easily return to the correct orientation under the influence of gravity and the push of subsequent sealing strips. When the rectangular push surface returns to its lowest point, the sealing strip can then smoothly slide onto it.
[0077] Thus, under the friction of multiple friction discs 26, the incorrectly oriented sealing strip can be actively deflected, and under the push of gravity and subsequent sealing strips, it can be transformed into the correct orientation. This significantly reduces the randomness of changing the sealing strip angle through the friction of the conveyor belt 2 and the thrust of the rectangular pushing surface, making it easier to adjust the sealing strip to the correct posture and ensuring the stability and continuity of subsequent testing work.
[0078] Example 3:
[0079] In the above embodiment, in order to make the friction disc 26 drive the sealing strip to rotate better, an anti-slip texture is provided on the surface of the friction disc 26. However, the anti-slip texture can also easily cause the sealing strip to get stuck when sliding towards the rectangular push surface, which will also affect the subsequent conveying work.
[0080] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:
[0081] like Figure 6 As shown, a booster assembly is provided on the material placement plate 22;
[0082] The booster assembly includes a plurality of strip-shaped through holes 28 opened laterally on the material plate 22 near one end of the material plate 24, and a number of actuating blocks 27 equal to the number of strip-shaped through holes 28, and each actuating block 27 passes through a strip-shaped through hole 28, and the plurality of actuating blocks 27 are fixedly connected by a connecting rod 37.

A sliding sleeve 21 is slidably connected to the sliding part of the sliding groove plate 23. The sliding rod 39 is slidably inserted through the sliding sleeve 21. A through hole rod 40 is rotatably provided in the middle of one end face of the rectangular groove plate 38. The guide post 41 is slidably inserted through the through hole of the through hole rod 40. A second motor 31 is fixedly connected to one end face of the rectangular groove plate 38. The output end of the second motor 31 is fixedly connected to one end of the through hole rod 40.
[0084] Specifically, whenever the rectangular push surface is at its lowest point, the friction disc 26 stops rotating, the motor 31 drives the through-hole rod 40 to rotate, and the through-hole rod 40 drives the guide column 41 to slide in the rectangular groove of the rectangular slot plate 38, so the slide rod 39 moves.
[0085] Furthermore, when the slide bar 39 moves, it slides on the sliding sleeve 21, and the sliding sleeve 21 slides at the groove of the sliding plate 23, thus keeping the slide bar 39 at a fixed angle. This allows the multiple actuating blocks 27 to move along a rectangular trajectory. The starting point of the actuating block 27 is located below the end of the strip-shaped through hole 28 near the conveyor belt 2. When the actuating block 27 rises, it passes through the strip-shaped through hole 28 and moves laterally along the length of the strip-shaped through hole 28, pushing the sealing strip stuck on the friction disc 26 towards the rectangular pushing surface. It then descends and moves out of the strip-shaped through hole 28. By repeating this operation, the actuating blocks 27 continuously push the sealing strip stuck on the friction disc 26, allowing the sealing strip to slide smoothly towards the rectangular pushing surface, ensuring smooth delivery of the sealing strip. Moreover, because the actuating blocks 27 move along a rectangular trajectory, they do not obstruct or push back subsequent sealing strips.
