Description

Technical Field

[0001] The present invention relates to the technical field of glass bead detection and sorting, and in particular to a glass bead defect detection and sorting device. Background Art

[0002] Glass beads used for reflective road markings in highway tunnels typically reflect light through optical reflection, creating a bright, reflective effect when illuminated by headlights. This enhances visibility and safety within the tunnel. To ensure this reflective effect within the tunnel, the glass beads require high reflective properties and durability, providing drivers with critical road guidance in dim environments and playing an important role in ensuring tunnel traffic safety.

[0003] In order to ensure the reflective effect of glass beads, it is generally necessary to classify and screen them according to the particle size, shape, density, transparency, etc. after production is completed. Among them, density and transparency screening rely heavily on defect detection, such as bubbles, cracks, impurities, etc. The accuracy of the detection directly affects the reflective performance and durability of road markings.

[0004] Currently, when inspecting and sorting glass beads, it is first necessary to remove defective beads that are too large or too small. During this process, the glass beads will produce debris, which will clog the sieve holes and affect the sorting effect and efficiency of the glass beads. In addition, the single or sequential use of air flow sorting, electrostatic sorting or automated robot sorting (robotic arms cooperate with detection probes to grab defective glass beads) is not only cumbersome to operate, affecting the inspection and sorting efficiency of the glass beads, but also increases the cost of glass bead inspection and sorting.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0036] Example:

[0037] Reference Figures 1-11 , a glass bead defect detection and sorting equipment, including a bracket 1 and an outer screen drum 2, the bracket 1 is fixedly connected to a feed hopper 11, the bottom end of the feed hopper 11 extends to the inside of the inner screen drum 10, that is, the glass beads are transported to the inside of the inner screen drum 10, and also includes: a drive shaft 4, which is rotatably connected to the side of the bracket 1 close to the outer screen drum 2, and a drive mechanism is provided between the drive shaft 4 and the bracket 1, for driving the drive shaft 4 to rotate, wherein a drive ring 8 that fits with the drive mechanism is fixedly connected to the outer wall of the outer screen drum 2; the inner screen drum 10 is rotatably connected to the inside of the outer screen drum 2, and a linkage component is provided between the inner screen drum 10 and the drive shaft 4. When the drive When the driving shaft 4 rotates, it is used to drive the inner sieve drum 10 to rotate at different speeds in the direction of the outer sieve drum 2; the anti-blocking mechanism is arranged on the driving shaft 4 and the outer sieve drum 2, and is used to blow air into the outer sieve drum 2 and the inner sieve drum 10 along the outside, and intermittently knock on the outer sieve drum 2 and the inner sieve drum 10; the guide hopper 30 is fixedly connected to the side of the bracket 1 close to the bottom end of the outer sieve drum 2 and the inner sieve drum 10, and the interior of the guide hopper 30 is symmetrically fixed with a partition plate 31, wherein the guide hopper 30 is provided with a detection and sorting mechanism connected to the driving shaft 4, which is used to sort glass beads with the same type of defects to the designated positions of the partition plate 31 and the guide hopper 30.

[0038] In this embodiment, the glass beads to be detected and sorted are added to the interior of the inner sieve drum 10 from the feed hopper 11, and the outer sieve drum 2 and the inner sieve drum 10 are driven to rotate by the driving mechanism and the linkage assembly. It should be explained that the size of the sieve holes of the inner sieve drum 10 is larger than the size of the sieve holes of the outer sieve drum 2, and the inner sieve drum 10 and the outer sieve drum 2 are both inclined. During the rotation of the inner sieve drum 10 and the outer sieve drum 2, the glass beads with large particle sizes stay in the interior of the inner sieve drum 10, and the glass beads with small particle sizes and qualified particle sizes fall into the outer sieve drum 2 under the action of gravity. Subsequently, the glass beads with small particle sizes fall from the interior of the outer sieve drum 2 to the outside under the action of gravity, thereby realizing the particle size sorting process of the glass beads. Furthermore, during the sorting process, the debris in the sieve holes of the outer sieve drum 2 and the inner sieve drum 10 can be cleaned by the anti-blocking mechanism to prevent the outer sieve drum 2 and the inner sieve drum 10 from being blocked. In addition, the outer sieve drum 2 and the inner sieve drum 10 can be knocked intermittently and evenly to further improve the anti-blocking effect of the outer sieve drum 2 and the inner sieve drum 10. The glass beads with qualified particle size after sorting fall onto the guide hopper 30, and the glass beads are sequentially subjected to air flow sorting, electrostatic sorting and automated robot sorting, and glass beads with different types of defects are placed at different positions along the guide hopper 30, which not only improves the detection and sorting effect of the glass beads, but also improves the detection accuracy of the glass beads.

[0039] Reference Figure 2 and Figure 10 The driving mechanism includes a driving motor 3 fixedly connected to the bracket 1 near one of the driving shafts 4. A driving wheel set 5 is provided on the driving motor 3 and the driving shaft 4. A first belt 6 is sleeved between the two driving wheel sets 5. A guide wheel 7 that fits with the driving ring 8 is fixedly connected to the driving shaft 4.

[0040] In this embodiment, when the glass beads are sorted, the drive motor 3 is started, and the drive shaft 4 is driven to rotate through the drive wheel group 5 and the first belt 6, thereby driving the guide wheel 7 to rotate. Under the action of the drive ring 8, the outer screen drum 2 is driven to rotate on the bracket 1. It should be accepted that a limiter can be provided on the guide wheel 7 so that the guide wheel 7 is always in close contact with the drive ring 8 when rotating. The guide wheel 7 drives the drive ring 8 to rotate mainly relying on the friction between the drive ring 8 and the guide wheel 7. This is a conventional means in the prior art and will not be elaborated on.

[0041] Reference Figure 1 and Figure 4 The linkage assembly includes a driven wheel group 12 fixedly connected to the drive shaft 4 and the inner screen drum 10. A second belt 13 is sleeved between the two sets of driven wheel groups 12 to drive the inner screen drum 10 and the outer screen drum 2 to rotate synchronously at different speeds.

[0042] In this embodiment, when the guide wheel 7 on one side close to the drive motor 3 rotates, the guide wheel 7 on the other side rotates synchronously under the action of the drive ring 8, and under the action of the driven wheel group 12 and the second belt 13, the inner sieve drum 10 is driven to rotate at different speeds along the rotation direction of the outer sieve drum 2, that is, at this time there is a tendency of relative rotation between the inner sieve drum 10 and the outer sieve drum 2. During this process, glass beads with large particle size stay in the inner sieve drum 10 and are gradually transported downward, and glass beads with small particle size fall from the inside of the outer sieve drum 2 to the outside, and glass beads with qualified particle size stay between the outer sieve drum 2 and the inner sieve drum 10.

[0043] Reference Figure 1 、 Figure 5 and Figure 6 The anti-blocking mechanism includes an air supply device 9 fixedly connected to the bracket 1 and connected to the drive shaft 4. The air outlet of the air supply device 9 is in contact with the outer wall of the outer sieve drum 2, and is used to blow the dust and the like blocked in the sieve holes of the outer sieve drum 2 to the inside of the outer sieve drum 2. An inner drum anti-blocking component is provided between the outer sieve drum 2 and the air supply device 9, and a vibration component is provided on the inner wall of the outer sieve drum 2.

[0044] In this embodiment, when the drive shaft 4 rotates, it drives the air supply device 9 to rotate. The specific structure of the air supply device 9 can refer to the technical solutions in the prior art, such as a centrifugal fan, that is, during the rotation of the outer sieve drum 2, the wind force generated by the air supply device 9 will be blown from the outside of the outer sieve drum 2 to the inside, thereby blowing the debris in the sieve hole to the inside of the outer sieve drum 2, thereby avoiding the blockage of the outer sieve drum 2 during sorting. It should be explained that when the outer sieve drum 2 rotates, the glass beads are always located at the bottom of the outer sieve drum 2 and roll under the action of gravity. Therefore, the glass beads that will not be sorted will not be discharged along the upper part of the outer sieve drum 2. The directional sorting of the glass beads can also be achieved by providing a protective cover on the outside of the outer sieve drum 2.

[0045] Reference Figure 4-Figure 6 The inner drum anti-blocking component includes an air slip ring 14 fixedly connected to the outer wall of the outer sieve drum 2, and an air supply pipe 15 is connected between the air slip ring 14 and the air supply device 9. A plurality of connecting shafts 16 are fixedly connected to the inner wall of the outer sieve drum 2, and a guide block 17 is fixedly connected to the connecting shaft 16, which is in contact with the inner wall of the outer sieve drum 2 and the outer wall of the inner sieve drum 10. An air blowing channel 18 is opened inside the guide block 17, wherein the exhaust port of the air blowing channel 18 is close to the outer wall of the inner sieve drum 10, and the air blowing channel 18 is connected to the air slip ring 14 through a pipeline.

[0046] In this embodiment, it needs to be explained that the air slip ring 14 is a conventional means in the prior art, which can realize the stable transportation of gas when the inner sieve drum 10 rotates, so it is not described in detail. That is, during the rotation of the outer sieve drum 2 and the inner sieve drum 10, part of the gas generated by the air supply equipment 9 first enters the interior of the air slip ring 14 through the air supply pipe 15, and then enters the interior of the guide block 17 through the pipeline, so that the gas is blown from the outside to the inside of the inner sieve drum 10, thereby cleaning the debris in the sieve holes of the inner sieve drum 10, and through the different speed rotation of the outer sieve drum 2 and the inner sieve drum 10, the sieve holes at different positions of the inner sieve drum 10 are evenly cleaned.

[0047] Reference Figure 5 、 Figure 6 and Figure 11 The vibration assembly includes a gear ring 19 fixedly connected to the outer wall of the inner sieve drum 10, a rotating shaft 20 is rotatably connected to the interior of the outer sieve drum 2, a driving gear 21 meshing with the gear ring 19 is fixedly connected to the rotating shaft 20, a collar 22 is fixedly connected to the rotating shaft 20, and multiple groups of sealing strips 23 are fixedly connected to the outer wall of the collar 22. A vibration strip 24 is slidably connected to the interior of the sealing strip 23, and multiple groups of springs 25 are fixedly connected between the vibration strip 24 and the sealing strip 23.

[0048] In this embodiment, when the outer sieve drum 2 and the inner sieve drum 10 rotate, under the action of the gear ring 19, the driving gear 21 and the rotating shaft 20 are driven to rotate, thereby driving the collar 22 and the sealing strip 23 to rotate. When the sealing strip 23 is away from the outer sieve drum 2 and the inner sieve drum 10, the vibration bar 24 extends outward under the action of the spring 25. When the sealing strip 23 is close to the outer sieve drum 2 and the inner sieve drum 10, the vibration bar 24 will knock on the outer sieve drum 2 and the inner sieve drum 10, and then the vibration bar 24 is received inside the sealing strip 23. By repeating the above process, different positions of the outer sieve drum 2 and the inner sieve drum 10 can be knocked intermittently and evenly, further improving the anti-blocking effect of the outer sieve drum 2 and the inner sieve drum 10.

[0049] Reference Figure 1 and Figure 3 , also includes a first discharge plate 27 and a second discharge plate 28 fixedly connected to the bracket 1, and a third discharge plate 29 is fixedly connected to the second discharge plate 28, the first discharge plate 27 is located at the bottom of the outer sieve drum 2, the second discharge plate 28 and the third discharge plate 29 are respectively close to the bottom end of the inner sieve drum 10 of the outer sieve drum 2, wherein a discharge port 26 is opened at the bottom end of the outer sieve drum 2, the size between the second discharge plate 28 and the third discharge plate 29 matches the discharge port 26, and the bottom end of the second discharge plate 28 is located above the guide hopper 30.

[0050] In this embodiment, small-sized glass beads fall downward through the outer sieve drum 2 and fall onto the first discharge plate 27, and gradually roll downward along the first discharge plate 27. The small-sized glass beads can be collected through the bottom end of the first discharge plate 27, while large-sized glass beads stay inside the inner sieve drum 10 and gradually roll downward along the inner sieve drum 10, and finally fall onto the third discharge plate 29. The large-sized glass beads can be collected through the bottom end of the third discharge plate 29; glass beads with qualified particle sizes roll between the outer sieve drum 2 and the inner sieve drum 10 to the second discharge plate 28, and finally fall from the bottom end of the second discharge plate 28 to the guide hopper 30, thereby realizing the particle size sorting of the glass beads.

[0051] Reference Figure 7 and Figure 9 The detection and sorting mechanism includes a guide member 32 fixedly connected to the side wall of the guide hopper 30. An air blowing pipe 33 is connected between the guide member 32 and the air supply device 9, which is used to blow the light defective glass beads to between the partition plate 31 on the side away from the guide member 32 and the guide hopper 30.

[0052] In this embodiment, when the glass beads fall from the second discharge plate 28 into the guide hopper 30, part of the gas generated by the air supply device 9 will be transported to the guide member 32 through the blowing pipe 33, and blown towards the falling glass beads through the guide member 32. The lighter glass beads will be blown to the side away from the guide member 32, and then fall between the partition plate 31 and the inner wall of the guide hopper 30. The glass beads with a normal mass will fall between the two groups of partition plates 31, thereby realizing the sorting of light defective glass beads.

[0053] Reference Figure 7-Figure 9 , and also includes a vertical shaft 34 rotatably connected to the side of the bracket 1 close to the guide member 32, a meshing bevel gear set 35 is provided between the vertical shaft 34 and the drive shaft 4, and a fixed plate 36 is fixedly connected to the side of the inner wall of the guide hopper 30 close to the guide member 32, and two groups of linkage shafts 37 are rotatably connected to the fixed plate 36, one group of linkage shafts 37 and the vertical shaft 34 are fixedly connected to a linkage wheel set 38, and a third belt 39 is sleeved between the two groups of linkage wheel sets 38, and rollers 40 are fixedly connected to the two groups of linkage shafts 37, and a conveyor belt 41 is sleeved on the roller 40, and an electrode plate 42 is fixedly connected to the side of the conveyor belt 41 away from the fixed plate 36, wherein the bottom of the electrode plate 42 is in contact with the partition plate 31 close to the side of the guide member 32, and the partition plate 31 is provided with a groove 45 matching the electrode plate 42.

[0054] In this embodiment, it is necessary to explain that an electrostatic field can be set between the partition plate 31 between the fixed plate 36 and the guide member 32, so that the glass beads after airflow sorting pass through the electrostatic field. In this process, the glass beads containing impurities are charged with static electricity and then adsorbed on the electrode plate 42. During the rotation of the drive shaft 4, the vertical shaft 34 is driven to rotate through the bevel gear set 35, thereby driving the linkage shaft 37 to rotate through the linkage wheel set 38 and the third belt 39, and driving the roller 40 and the conveyor belt 41 to rotate. The electrode plate 42 is made of soft material. As the electrode plate 42 rotates, the adsorbed The glass beads on its surface move toward the side close to the guide member 32. When passing through the groove 45, the glass beads will not fall off. When the electrode plate 42 rotates toward the partition plate 31, the partition plate 31 will scrape off the glass beads adsorbed on the electrode plate 42, and then fall between the partition plate 31 and the inner wall of the guide hopper 30. The glass beads without impurities continue to be transported between the two groups of partition plates 31. In addition, the size of the gap between the electrode plate 42 and the partition plate 31 is smaller than the size of a single glass bead to ensure that the glass beads on the electrode plate 42 are scraped off thoroughly, while also reducing the cost of glass bead detection and sorting.

[0055] Reference Figure 7 , and also includes a mounting plate 43 fixedly connected to the guide hopper 30. A detection probe 44 is fixedly connected to the side of the mounting plate 43 close to the guide hopper 30. The detection probe 44 is located above between the two sets of partition plates 31. The glass beads pass through the guide member 32, under the electrode plate 42 and under the detection probe 44 in sequence. A robotic arm electrically connected to the detection probe 44 is provided on the guide hopper 30.

[0056] In this embodiment, the detection probe 44 adopts a visual system to detect tiny defects in glass beads. The robotic arm is electrically driven and cooperates with PLC or PC to control the timing. The detection probe 44 accurately detects the position of defective glass beads. The detection signal is transmitted to the robotic arm, driving the robotic arm to grab the defective glass beads and place the glass beads at the designated position. It should be explained that before this detection method, most of the defective glass beads have been eliminated. At this time, only a very small number of defective glass beads remain. That is, while ensuring the accuracy of glass bead detection and sorting, the impact on the glass bead detection and sorting efficiency is reduced to prevent omissions.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
