Description

Technical Field

[0001] This invention relates to the field of ceramic brush inspection technology, specifically a visual inspection device based on ceramic brush production and processing. Background Technology

[0002] Ceramic brushes are specialized tools used in the industrial field for grinding, polishing, and deburring. Their bristles contain abrasive materials such as ceramic fibers, giving them high grinding power and stability.

[0003] As a precision industrial and cleaning consumable, the bristle distribution, brush handle coaxiality, end face flatness, and appearance defects of ceramic brushes directly affect their performance and lifespan. Current ceramic brush production and inspection methods mostly rely on manual visual sampling or single-sided fixed visual inspection, which presents the following prominent problems: 1. Low inspection efficiency: Manual inspection is slow and inconsistent, and cannot keep up with the continuous production cycle of automated production lines; 2. Incomplete inspection: Conventional vision devices can only photograph a single surface of the ceramic brush. The brush bristle surface, brush handle surface, and sides require multiple loading and secondary inspections, resulting in a high rate of missed detections. 3. Difficulty in determining coaxiality: Whether the brush rod is centered or not, and whether it is eccentrically bent, are difficult to quickly quantify and judge manually or with a conventional camera, which can easily lead to defective products flowing into the later stages; 4. Low level of automation: It lacks an integrated mechanism for automatic clamping, flipping and rotating, requiring manual assistance for flipping and positioning, which increases labor costs and the risk of bumps and knocks.

[0004] Therefore, based on the above problems, we have invented a visual inspection device based on ceramic brush production and processing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a visual inspection device based on ceramic brush production and processing, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a visual inspection device for ceramic brush production and processing, comprising three substrates, two transport rollers between each pair of adjacent substrates, multiple transport rollers rotatably mounted with the substrates, and an association cavity within the two middle substrates, wherein one end of each of the two transport rollers rotatably extends through the substrate into the association cavity and is connected by a transmission gear set, a conveyor belt is connected between the two transport rollers on the same side, multiple placement plates are mounted on the surface of the conveyor belt, a power motor is mounted outside the substrate, one end of the power motor rotatably extends through the substrate and is coaxially mounted with the transport roller, vertical plates are fixedly connected to the upper ends of the two side substrates, a horizontal plate is fixedly connected between the two vertical plates, two cameras are mounted at the lower end of the horizontal plate, the two cameras are respectively matched with two conveyor belts, and a flipping mechanism for visual inspection of ceramic brushes is provided on the middle substrate.

[0007] Furthermore, the transmission gear set includes two transmission gears, which are coaxially mounted with two transport rollers respectively, and are meshed with each other.

[0008] Furthermore, the flipping mechanism includes a T-shaped plate disposed above the substrate. The T-shaped plate is rotatably mounted to the substrate via two fixed plates. A rotating mechanism for rotating the T-shaped plate is provided between the two fixed plates. The T-shaped plate has two moving slots, and clamping arms are slidably mounted through each of the two moving slots. A crossbar is fixedly connected to one end of each clamping arm opposite to the other. An outer clamping plate is fixedly connected to one end of the crossbar away from the clamping arms. An inner clamping plate is slidably mounted inside the outer clamping plate. A fixing washer is fixed inside the inner clamping plate. The T-shaped plate has a steering mechanism for rotating the inner clamping plate and a moving mechanism for moving the two clamping arms.

[0009] Furthermore, the rotating mechanism includes a rotating shaft that rotates through two fixed plates. Each of the two fixed plates is provided with a connecting shaft that rotates through it. The two connecting shafts are respectively fixedly connected to both ends of the T-shaped plate. The rotating shafts located on the same side are connected to each other through a transmission mechanism. A rotating motor is mounted on one of the fixed plates, and the drive shaft of the rotating motor is coaxially mounted with the rotating shaft.

[0010] Furthermore, the transmission mechanism includes a first pulley and a second pulley. The first pulley is coaxially mounted with the rotating shaft, and the second pulley is coaxially mounted with the connecting shaft. The first pulley and the second pulley are connected by a synchronous belt drive.

[0011] Furthermore, the steering mechanism includes two limiting plates fixedly connected to the T-shaped plate. A steering shaft is rotatably mounted between the two limiting plates, and the steering shaft rotatably passes through the T-shaped plate. A steering motor is mounted on the limiting plates, and the drive shaft of the steering motor rotatably passes through the limiting plates and is coaxially mounted with the steering shaft. A transmission groove is provided through each of the two clamping arms, and the steering shaft passes through the transmission groove. A transition shaft is rotatably mounted within the transmission groove, and a second bevel gear is coaxially mounted on the transition shaft. A sliding sleeve is slidably mounted outside the steering shaft, with both ends of the sliding sleeve rotatably mounted to the inner wall of the transmission groove. A first bevel gear is coaxially mounted outside the sliding sleeve, and the first bevel gear interacts with the second bevel gear. The gears are meshed together. The clamping arm has a transmission cavity. One end of the transition shaft rotatably passes through the clamping arm and extends into the transmission cavity. The transmission cavity has a rotating shaft. A third bevel gear is coaxially mounted on the transition shaft. A fourth bevel gear is coaxially mounted on the rotating shaft. The third and fourth bevel gears are meshed together. The inner wall of the outer clamping plate has an annular cavity. An arc-shaped rack is rotatably mounted in the annular cavity. The arc-shaped rack is fixedly connected to the inner clamping plate. One end of the rotating shaft rotatably passes through the clamping arm, the crossbar, and the outer clamping plate and is coaxially mounted with a steering gear. The arc-shaped rack meshes with the steering gear. Both the outer and inner clamping plates have matching limiting blocks and limiting grooves.

The bidirectional screw rotates through the T-shaped plate and the moving slot, and the bidirectional screw threadedly passes through the two clamping arms.

[0013] Furthermore, multiple placement plates are arranged in an array on the conveyor belt, and the placement plates are provided with insertion holes that match the ceramic brushes.

[0014] Compared with the prior art, the present invention provides a visual inspection device based on ceramic brush production and processing, which has the following beneficial effects: 1. By setting up a flipping mechanism, combined with a dual conveyor belt and dual camera layout, it can complete full-coverage visual inspection of the ceramic brush bristles, brush rod end face, and circumferential side in one go, without the need for secondary feeding and repeated positioning, significantly reducing the missed detection rate, and with a high degree of automation, improving inspection efficiency.

[0015] 2. By setting a steering mechanism, the ceramic brush is rotated 360°. The camera captures the edge contour in real time, which can quickly determine whether the brush rod is centered and whether there is any eccentric deformation. This achieves automated quantitative detection of the brush rod coaxiality, with an accuracy far higher than that of manual visual inspection. Furthermore, the flexible clamping of the fixed washer, combined with the positioning constraint of the limit block and limit groove, ensures a stable and reliable clamping process, avoiding scratches on the ceramic brush surface and deformation of the bristles, thus ensuring the integrity of the product.

[0016] This application enables fully automated visual inspection of both sides of ceramic brushes, automatic flipping and 360° rotation coaxiality inspection, which is comprehensive, efficient and highly accurate. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0020] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a visual inspection device based on ceramic brush production and processing.

[0021] like Figures 1-8 As shown, a visual inspection device based on ceramic brush production and processing includes three substrates 1. Two transport rollers 2 are provided between each pair of adjacent substrates 1. Multiple transport rollers 2 are rotatably mounted to the substrates 1. The two middle substrates 1 have an association cavity 48. One end of each of the two transport rollers 2 rotatably extends through the substrate 1 into the association cavity 48 and is connected by a transmission gear set 5. Specifically, the transmission gear set 5 includes two transmission gears 6, which are coaxially mounted with the two transport rollers 2 respectively and are meshed together. A conveyor belt 3 is connected between the two transport rollers 2 on the same side. Multiple placement plates 4 are mounted on the surface of the conveyor belt 3. It should be noted that the multiple placement plates 4 are arranged in an array on the conveyor belt 3. The placement plates 4 are provided with insertion holes that match the ceramic brushes. A power motor 7 is mounted on the outside of the base plate 1. One end of the power motor 7 rotates through the base plate 1 and is coaxially mounted with the transport roller 2. Vertical plates 8 are fixedly connected to the upper ends of the base plates 1 on both sides. A horizontal plate 9 is fixedly connected between the two vertical plates 8. Two cameras 10 are mounted on the lower end of the horizontal plate 9. The two cameras 10 are respectively matched with the two conveyor belts 3. A flipping mechanism 11 for visual inspection of the ceramic brushes is provided on the base plate 1 in the middle.

[0022] To detect the flipping of the ceramic brush, a flipping mechanism 11 is provided. The flipping mechanism 11 includes a T-shaped plate 12 positioned above the substrate 1. The T-shaped plate 12 is rotatably mounted to the substrate 1 via two fixed plates 14. A rotating mechanism 13 for rotating the T-shaped plate 12 is provided between the two fixed plates 14. Further, the rotating mechanism 13 includes a rotating shaft 15 that rotatably passes through the two fixed plates 14. A connecting shaft 16 rotatably passes through each of the two fixed plates 14, and the two connecting shafts 16 are respectively fixedly connected to both ends of the T-shaped plate 12. The rotating shafts 15 on the same side are connected by a transmission mechanism 18. It should be noted that the transmission mechanism 18 includes a first pulley 19 and a second pulley 20. The first pulley 19 is coaxially mounted with the rotating shaft 15, and the second pulley 20 is coaxially mounted with the connecting shaft 16. The first pulley 19 and the second pulley 20 are connected by a synchronous belt. One of the fixed plates... A rotary motor 17 is mounted on plate 14. The drive shaft of the rotary motor 17 is coaxially mounted with the rotating shaft 15. Two moving slots 28 are provided on T-shaped plate 12. Clamping arms 21 are slidably mounted through both moving slots 28. A crossbar 23 is fixedly connected to the opposite end of each clamping arm 21. An outer clamping plate 24 is fixedly connected to the end of the crossbar 23 away from the clamping arm 21. An inner clamping plate 25 is slidably mounted inside the outer clamping plate 24. A fixing washer 26 is fixed inside the inner clamping plate 25. A steering mechanism 27 for rotating the inner clamping plate 25 is provided on T-shaped plate 12. A moving mechanism 22 for moving the two clamping arms 21 is provided on T-shaped plate 12. It is worth mentioning that the moving mechanism 22 includes a moving motor 30. A bidirectional screw 29 is coaxially mounted on the drive shaft of the moving motor 30. The bidirectional screw 29 is rotatably mounted through T-shaped plate 12 and moving slots 28. The bidirectional screw 29 is threaded through the two clamping arms 21.

[0023] Through the above technical features: when the ceramic brush is transported to the designated location, the camera 10 performs visual inspection on the bristle side. After the inspection is completed, the drive shaft of the moving motor 30 drives the bidirectional screw 29 to rotate. The bidirectional screw 29 drives the two clamping arms 21 to move relative to each other. The two clamping arms 21 drive the outer clamping plate 24 to move relative to each other through the crossbar 23 until the ceramic brush is clamped and fixed. At this time, the drive shaft of the rotating motor 17 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the two connecting shafts 16 to rotate. The connecting shafts 16 drive the T-shaped plate 12 to rotate. The T-shaped plate 12 drives the ceramic brush to flip through the clamping arms 21 and the outer clamping plate 24. The reverse side of the ceramic brush can then be inspected by another camera 10. This allows for comprehensive visual inspection of the ceramic brush from all angles, eliminating the need for subsequent secondary inspections and improving the inspection efficiency of the ceramic brush.

[0024] To detect whether the brush handle of the ceramic brush is at the central axis position, a steering mechanism 27 is provided. The steering mechanism 27 includes two limiting plates 31 fixedly connected to the T-shaped plate 12. A steering shaft 32 is rotatably mounted between the two limiting plates 31, and the steering shaft 32 rotatably passes through the T-shaped plate 12. A steering motor 33 is mounted on the limiting plates 31. The drive shaft of the steering motor 33 rotatably passes through the limiting plates 31 and is coaxially mounted with the steering shaft 32. A transmission groove 34 is provided through both clamping arms 21, and the steering shaft 32 passes through the transmission groove 34. A transition shaft 38 is rotatably mounted inside the transmission groove 34. A second bevel gear 37 is coaxially mounted on the transition shaft 38. A sliding sleeve 35 is slidably mounted outside the steering shaft 32. Both ends of the sliding sleeve 35 are rotatably mounted with the inner wall of the transmission groove 34. A first bevel gear 36 is coaxially mounted outside the sliding sleeve 35. The bevel gear 36 and the second bevel gear 37 are meshed together. The clamping arm 21 is provided with a transmission cavity 42. One end of the transition shaft 38 rotatably passes through the clamping arm 21 and extends into the transmission cavity 42. The transmission cavity 42 is provided with a rotating shaft 39. The transition shaft 38 is coaxially mounted with a third bevel gear 40, and the rotating shaft 39 is coaxially mounted with a fourth bevel gear 41. The third bevel gear 40 and the fourth bevel gear 41 are meshed together. The inner wall of the outer clamping plate 24 is provided with an annular cavity 43. An arc-shaped rack 44 is rotatably mounted in the annular cavity 43. The arc-shaped rack 44 is fixedly connected to the inner clamping plate 25. One end of the rotating shaft 39 rotatably passes through the clamping arm 21, the crossbar 23 and the outer clamping plate 24 and is coaxially mounted with a steering gear 45. The arc-shaped rack 44 is meshed with the steering gear 45. The outer clamping plate 24 and the inner clamping plate 25 are both provided with matching limiting blocks 46 and limiting grooves 47.

[0025] Through the above technical features: the drive shaft of the steering motor 33 drives the steering shaft 32 to rotate, the steering shaft 32 drives the two transition shafts 38 to rotate, the two transition shafts 38 drive the two rotating shafts 39 to rotate, the two rotating shafts 39 drive the two steering gears 45 to rotate synchronously, the steering gears 45 drive the inner clamping plate 25 to rotate through the arc rack 44, and the inner clamping plate 25 drives the ceramic brush to rotate through the fixing washer 26, so that the ceramic brush rotates one revolution. During the rotation, the brush rod of the ceramic brush can be judged by the edge position of the ceramic brush at various time points to determine whether it is at the central axis. The detection of the ceramic brush is relatively simple.

[0026] Working principle: Inspection of the brush bristles: Insert the ceramic brush into the insertion hole on the placement plate 4. Drive the conveyor roller 2 to rotate through the power motor 7. The conveyor roller 2 drives the conveyor belt 3 to rotate. The conveyor belt 3 drives the placement plate 4 to rotate until the placement plate 4 moves below the camera 10. At this time, the camera 10 performs visual inspection on the brush bristles. For brush rod side detection: The drive shaft of the moving motor 30 drives the bidirectional screw 29 to rotate. The bidirectional screw 29 drives the two clamping arms 21 to move relative to each other. The two clamping arms 21 drive the outer clamping plate 24 to move relative to each other through the crossbar 23 until the ceramic brush is clamped and fixed. At this time, the drive shaft of the rotating motor 17 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the two connecting shafts 16 to rotate. The connecting shafts 16 drive the T-shaped plate 12 to rotate. The T-shaped plate 12 drives the ceramic brush to flip over through the clamping arms 21 and the outer clamping plate 24. When it is below the other camera 10, the brush rod side of the ceramic brush can be detected through the other camera 10. The detection process involves the steering motor 33 driving the steering shaft 32 to rotate, which in turn drives two transition shafts 38 to rotate. These two transition shafts 38 then drive two rotating shafts 39 to rotate, which in turn drive two steering gears 45 to rotate synchronously. The steering gears 45, through the arc-shaped rack 44, drive the inner clamping plate 25 to rotate. The inner clamping plate 25, through the fixing washer 26, drives the ceramic brush to rotate, causing the ceramic brush to rotate one revolution. During this rotation, the position of the ceramic brush at various points in time can be used to determine whether the brush handle is on the central axis. This method of detecting ceramic brushes is relatively simple and comprehensive.

[0027] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0028] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this invention.
