Description

Technical Field

[0001] This invention relates to the field of compressor component testing technology, and in particular to a compressor component component identification device. Background Technology

[0002] In the production and quality control of compressor components, with the increasing demands for lightweight, high strength, and corrosion resistance, the materials used for components have gradually expanded from traditional gray cast iron and carbon steel to new materials such as ductile iron, alloy cast aluminum, duplex stainless steel, and even fiber-reinforced composite materials. To ensure that the composition of these new materials meets design specifications and that there are no casting or processing defects such as cracks, sand holes, or porosity on the surface, automated identification and inspection of their appearance is usually required. Existing inspection equipment often uses a conveyor mechanism to sequentially transport materials to the cleaning station and the visual inspection station. High-resolution images of the material surface are acquired by fixed industrial cameras, and combined with multi-angle supplementary lighting devices and artificial intelligence image analysis algorithms, online imaging analysis and judgment of material identification and surface defects are completed. In addition, to meet the requirements of downstream OEMs and industry regulators, relevant inspection data and process records must be incorporated into the company's quality management system and subject to audit and supervision by third-party certification and accreditation services to ensure the accuracy, traceability, and compliance of the inspection results, thereby providing full-process assurance for the quality reliability of compressor components.

[0003] Currently, identification and testing equipment only performs single-cycle, fixed-direction airflow cleaning, which is insufficient to cover complex structural areas such as grooves, steps, screw holes, and chamfered edges. This easily creates cleaning blind spots, preventing the complete removal of impurities embedded in the texture. Residual impurities cause artifacts or occlusions during visual inspection, leading to misjudgment of composition or missed defects. Furthermore, the material transfer process only involves one cleaning cycle, and the trace amounts of dust that fall after placement can re-contaminate the treated surface, making it difficult to maintain consistent cleanliness before entering the inspection station. In the visual inspection stage, conventional equipment uses a fixed-view camera array to photograph stationary or unidirectionally moving materials. When dealing with multi-curved, multi-step compressor components, there are inherent blind spots. Information on sidewalls, recessed inner walls, and edge transition areas is difficult to collect completely, and hidden defects such as microcracks and subcutaneous pores are easily missed. In addition, the fixed-position light source projects at a constant angle, creating obvious shadows on the material's structural contours. Insufficient illumination at the bottom of recesses and the root of protrusions reduces imaging contrast, further exacerbating the loss of feature information and affecting the accurate interpretation of component boundaries and defect morphology.

[0009] The connecting rod has an L-shaped drive arm fixedly installed at the end away from the support cylinder. The swing base plate has an arc-shaped drive groove that matches the size of the L-shaped drive arm. The L-shaped drive arm moves in the arc-shaped drive groove. The blower nozzle moves on both sides of the top of the gripping plate to clean the upper surface of the material at the bottom of the fixed suction cup.

The top of the piston rod passes through the blower and is fixedly installed at the bottom of the piston plate. The top of the blower has an air outlet pipe and an air inlet pipe. The air outlet pipe is connected to the arc-shaped cleaning seat.

[0010] As a preferred embodiment of the present invention, a cross-shaped fixing frame is fixedly installed at both ends of the top of the U-shaped base plate. A first slider is slidably connected to the cross-shaped fixing frame in the horizontal direction, and a second slider is slidably connected to the cross-shaped fixing frame in the vertical direction. The package detection component also includes a fixed gear and a movable gear. A base plate is fixedly installed at both ends of the top of the U-shaped base plate. A connecting plate is movably connected between the first slider and the second slider through a rotating shaft. A movable gear is provided at the center of the connecting plate. A fixed gear is connected to the top of the base plate through a rotating shaft. The movable gear meshes with the fixed gear.

A drive rod is fixedly installed at the output end of the rotary motor. Second pulleys are fixedly installed at both ends of the drive rod. A transmission belt is connected between the first pulley and the second pulley.

[0011] A carrier plate is fixedly installed between the first sliders, and an equipment plate is fixedly installed between the second sliders. The carrier plate is made of transparent material and places the material under the fixed suction cup on the carrier plate. Several vision cameras are staggered on the equipment plate and perform top and bottom detection on the material on the carrier plate.

[0012] As a preferred embodiment of the present invention, a U-shaped support plate is fixedly installed at the top center of the U-shaped base plate, a reciprocating rod is movably inserted through the U-shaped support plate, supplementary lights are fixedly installed at both ends of the reciprocating rod, a rotating cylinder is fixedly installed at the center of the drive rotating rod, an annular actuation groove is opened on the outer periphery of the rotating cylinder, and the motion supplementary lighting component also includes a T-shaped actuation rod, one end of the T-shaped actuation rod is movably fitted in the annular actuation groove, and the other end is fixedly connected to the reciprocating rod.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. In this invention, the moving plate is driven to perform a looping motion with two descents and two ascents through the precise meshing transmission of the moving gear and the toothed column in the material lifting and cleaning component. The action is compact and smooth, with the two descents precisely corresponding to the picking position on the surface of the conveyor roller and the placement position on the transparent carrier plate, respectively. During the horizontal transfer, the top of the connecting rod is continuously constrained and guided by the U-shaped chute, effectively suppressing lateral movement and ensuring that materials of various materials and weights maintain a stable posture without swaying or slipping after leaving the conveyor surface. This not only provides a stable clamping base for subsequent swinging and blowing cleaning but also ensures the positional repeatability accuracy of the material when it falls into the carrier plate, creating favorable conditions for accurate alignment of the surround vision inspection and meeting the higher requirements for the stability of picking and placing new material components due to differences in density and surface characteristics.

[0014] 2. In this invention, two high-pressure blower cleaning processes are triggered synchronously through mechanical linkage, combined with the reciprocating swing of the blower nozzles, to form a unique dynamic oscillating air curtain cleaning effect. When the moving plate rises, it drives the piston rod and piston plate to move upward synchronously, and the volume of the blower cavity is rapidly compressed to generate high-pressure gas. The high-pressure airflow pushes open the one-way valve of the air outlet and flows into the inner cavity of the arc-shaped cleaning seat. The continuous rotation of the connecting rod, through the reciprocating sliding of the end of the L-shaped drive arm in the arc-shaped drive groove, forces the swinging base plate to swing at a high frequency around the hinge point. The blower nozzles evenly arranged at the bottom of the arc-shaped cleaning seat sweep back and forth along the arc path on both sides of the top of the material, forming a dynamic oscillating air curtain. The airflow is sprayed out from the nozzles that constantly change the spray angle, and repeatedly flushes the material's planar area, edge chamfers, groove steps, and screw hole perimeters and other areas prone to dust accumulation from multiple angles and in different directions. Impurities are completely stripped off and quickly rolled away, eliminating the dead corners and secondary deposition common in fixed air cleaning. It is especially suitable for new materials that are sensitive to surface cleanliness, such as fiber-reinforced composite materials, to ensure that the detection imaging surface is unobstructed.

[0015] 3. In this invention, the timing of the two air-blowing cleaning cycles is perfectly matched with the feeding action rhythm, achieving dual cleanliness assurance of initial cleaning after gripping and re-cleaning after unloading. The first upward air-blowing cleaning occurs the instant the material leaves the conveyor roller, when the impurities adhering to the material surface during the conveying process are at their loosest. The oscillating air curtain quickly removes them with a powerful sweeping motion. The second air-blowing cleaning during the reset and upward phase after unloading finely cleans any traces of dust that may have fallen or remained during placement. The material is now stably placed on the surface of the support plate, and the airflow sweeping is more uniform and delicate. In addition, the triangular limiting blocks and the triangular limiting plate engaging structure at the upper and lower ends of the feeding side plate ensure that the loop motion frame maintains a stable posture during continuous operation, with no obvious shaking during the movement. When the fixed suction cup descends to grip, it can accurately align with the center of the material on the conveyor roller, and the gripping force is uniform and reliable. This further ensures that the cleaning airflow fully covers the material surface and the cleaning effect is consistent. Subsequent visual inspection provides a clean and unobstructed imaging surface, ensuring accurate identification of minor defects (such as pores and sand holes) on the surface of materials such as ductile iron and alloy cast aluminum.

[0016] 4. In this invention, through the meshing transmission of the movable gear and the fixed gear in the package detection assembly, and the linkage deflection of the connecting plate, the first slider and the second slider are driven to slide synchronously on the cross-shaped fixing frame in mutually perpendicular directions. This causes the carrying plate to move the material horizontally while the device plate drives the vision camera to reciprocate vertically, and the two combine to form a wrap-around three-dimensional scanning trajectory. When the second slider moves vertically from bottom to top, the device plate rises synchronously, and the first slider moves the material horizontally from one end of the cross-shaped fixing frame to the other end, forming an oblique scanning path from bottom to top and from one end to the other. When the second slider rises to the top and turns to move downwards, the device plate descends accordingly, and the first slider... This causes the support plate to reverse horizontally, forming an oblique scanning path from top to bottom and back to the starting side from the other side. The two sets of oblique scanning trajectories in opposite directions interweave on the upper and lower sides of the material. The shooting angle and framing position of the vision camera change continuously with the movement, effectively eliminating blind spots and dead angles caused by the material's own structure in fixed-view detection. It can achieve all-round and complete imaging coverage of all sides, edges, chamfers, and concave and convex parts of the material. Whether it is the edge chamfer of alloy cast aluminum parts, the concave and convex parts of duplex stainless steel parts, or the interlayer structure of fiber reinforced composite materials, it can achieve all-round and complete imaging coverage, providing complete image basis for subsequent component analysis and defect judgment.

[0017] 5. In this invention, multiple vision cameras arranged in a staggered pattern on the equipment plate continuously photograph the material on the support plate from different installation heights and horizontal starting positions as the equipment plate reciprocates horizontally. Each time the equipment plate completes a complete vertical lifting and lowering cycle from bottom to top and back, the imaging area of ​​the vision cameras completes two horizontal coverages of the material surface in opposite directions. After multiple cycles and superpositions, every area on the upper and lower surfaces of the material is covered by multiple cameras at different angles and distances, resulting in rich and highly redundant imaging data. The transparent support plate allows the vision cameras arranged below to simultaneously penetrate the support plate and clearly image the lower surface of the material, forming a vertical linkage with the cameras above. This is suitable for components with large differences in surface texture, such as ductile iron and duplex stainless steel, ensuring that the features of the upper and lower surfaces, potential cracks, or sand holes are completely recorded, providing sufficient and accurate image basis for subsequent artificial intelligence image analysis algorithms.

[0018] 6. In this invention, the precise cooperation between the annular actuating groove on the outer periphery of the rotating cylinder and the T-shaped actuating rod in the motion supplementary lighting assembly efficiently transforms the rotational motion of the driving rod into the horizontal linear reciprocating motion of the reciprocating rod. The supplementary light then moves back and forth at the bottom of the support plate in sync with the visual inspection scanning rhythm. The light penetrates the transparent support plate from the continuously moving light source position and illuminates the lower surface of the material. The dynamic change of the light source position ensures that each area at the bottom of the material is illuminated by light from different directions and different incident angles, effectively eliminating the shadows and uneven illumination caused by the material's own structural contours under fixed light source illumination conditions. The horizontal reciprocating motion of the supplementary light covers the full width of the support plate area. No matter where the material is placed on the support plate, its bottom can be evenly covered by the moving light spot. Combined with the circumferential motion trajectory of the visual camera, it ensures that the upper and lower surfaces of the material maintain consistent brightness and clear contrast throughout the entire image acquisition cycle, significantly improving the imaging quality and the accuracy of subsequent interpretation. This provides technical support for meeting the stringent requirements of downstream OEMs and third-party certification and accreditation audits for the accuracy and traceability of test data.

[0021] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a compressor component composition identification device includes a frame 10 with a conveyor roller 11. An identification frame 12 is fixedly installed on the top of the frame 10. A feeding side plate 20 is fixedly installed on the inner side of the identification frame 12. A material lifting and cleaning component for feeding material on the conveyor roller 11 is provided on the feeding side plate 20. A fixed suction cup 41 is provided on the component to adsorb and grasp the material. The material lifting and cleaning component includes a loop motion frame 23, a motion gear 35, and a support cylinder 30. Triangular limit blocks 21 are fixedly installed at the upper and lower ends of the feeding side plate 20. A triangular limit plate 22 is movably connected to the outer periphery of the triangular limit blocks 21. The loop motion frame 23 is fixedly installed on the triangular limit plate 22. Between 2, the material lifting and cleaning assembly also includes a toothed column 28 fixedly installed on the feeding side plate 20, a fixed slide groove 24 is opened inside the loop motion frame 23, a fixed slider 25 is slidably connected in the fixed slide groove 24, a motion plate 26 is fixedly installed between the fixed sliders 25, a support cylinder 30 is fixedly installed at the center of the side of the motion plate 26 away from the feeding side plate 20, a connecting rotating rod 32 is movably arranged at the center inside the support cylinder 30, a motion gear 35 is fixedly installed through the support cylinder 30 and the motion plate 26, the motion gear 35 moves around the outer periphery of the toothed column 28, and the tooth pitch of the motion gear 35 matches the size of the toothed column 28.

[0023] The feeding side plate 20 has a U-shaped slide groove 27. The size of the U-shaped slide groove 27 matches the size of the connecting rotating rod 32. The top of the connecting rotating rod 32 moves in the U-shaped slide groove 27. A gripping plate 40 is fixedly installed at the bottom of the moving plate 26. Several fixed suction cups 41 are evenly fixedly installed at the bottom of the gripping plate 40.

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The servo motor 31 output shaft rotates, driving the connecting rod 32 to rotate within the support cylinder 30. The motion gear 35, fixed at the end of the connecting rod 32, rotates synchronously. Because the motion gear 35 meshes with the toothed column 28 fixed to the surface of the feeding side plate 20, it is forced to roll along the outer circumference of the toothed column 28 while rotating, generating a compound motion of revolution around the toothed column 28. This motion is transmitted to the motion plate 26 via the connecting rod 32, causing the motion plate 26, along with the fixed sliders 25 on both sides, to perform alternating vertical lifting and horizontal translational motions within the fixed groove 24 of the loop motion frame 23. The engaging structure of the triangular limiting plate 22 and the triangular limiting block 21 ensures that the loop motion frame 23 maintains a stable posture with no significant shaking during movement, ensuring that the fixed suction cup 41 accurately aligns with the center of the material on the conveyor roller 11 when it descends to grab it.

[0025] As the moving plate 26 descends, the fixed suction cup 41 at the bottom of the gripping plate 40 moves downwards to contact the material in the compressor components. Upon energization, the fixed suction cup 41 instantly creates a vacuum chamber, firmly adhering to the material surface. Even during subsequent rapid ascent and lateral movement, the material will not shift or fall off. The moving plate 26 then rises, lifting the material off the conveying surface. A horizontal lateral movement then smoothly transfers the material to the next workstation. Throughout the entire transfer process, the top of the connecting rod 32 remains constrained within the U-shaped groove 27 on the loading side plate 20, limiting the horizontal movement of the moving plate 26 and effectively ensuring the positioning accuracy of the material upon arrival at the placement station. Finally, the moving plate 26 descends again, the fixed suction cup 41 is de-energized, releasing the vacuum, and the material is gently released onto the surface of the support plate 68, completing a highly efficient and stable feeding action from gripping to transfer and placement.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The support cylinder 30 is also equipped with a reciprocating swing assembly for swinging and blowing clean the gripped material. The blowing nozzles 44 on the support cylinder 30 swing back and forth on both sides of the top of the material. The reciprocating swing assembly includes a connecting rod 32, a swing base plate 42, and an arc-shaped cleaning seat 43. A servo motor 31 is fixedly installed on the top of the support cylinder 30 through a motor plate. A first bevel gear 33 is fixedly installed inside the support cylinder 30 through the connecting rod 32. A second bevel gear 34 is fixedly installed on the output end of the servo motor 31 through a rotating shaft. The second bevel gear 34 and the first bevel gear 33 are movably meshed. The reciprocating swing assembly also includes an L-shaped drive arm 36. The top of the gripping plate 40 is movably connected to the swing base plate 42 through a hinge. An arc-shaped cleaning seat 43 is fixedly installed on the top of the swing base plate 42. The arc-shaped cleaning seat 43 has an H-shaped structure. Several blowing nozzles 44 are evenly installed at the bottom of both ends of the arc-shaped cleaning seat 43.

[0027] An L-shaped drive arm 36 is fixedly installed at the end of the connecting rod 32 away from the support cylinder 30. The swing base plate 42 has an arc-shaped drive groove 45 that matches the size of the L-shaped drive arm 36. The L-shaped drive arm 36 moves in the arc-shaped drive groove 45. The blower nozzle 44 moves on both sides of the top of the gripping plate 40 to clean the upper surface of the material at the bottom of the fixed suction cup 41. A blower 50 is fixedly installed on the top of the U-shaped motion frame 23. A piston plate 51 is movably arranged inside the blower 50. A piston rod 52 is fixedly installed on the top of the motion plate 26. The top of the piston rod 52 passes through the blower 50 and is fixedly installed at the bottom of the piston plate 51. An air outlet pipe 53 and an air inlet pipe 54 are provided on the top of the blower 50. The air outlet pipe 53 is connected to the arc-shaped cleaning seat 43. One-way valves are provided on both the air outlet pipe 53 and the air inlet pipe 54 to ensure one-way gas discharge.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The output shaft of the servo motor 31, fixedly mounted on the top of the support cylinder 30 via the motor plate, rotates, driving the second bevel gear 34 to rotate. The second bevel gear 34 meshes with and drives the first bevel gear 33 fixed on the connecting rod 32 to rotate, thereby causing the connecting rod 32 to generate continuous self-rotation motion inside the support cylinder 30. An L-shaped drive arm 36 is fixedly mounted on the end of the connecting rod 32 away from the support cylinder 30. The L-shaped drive arm 36 rotates together with the connecting rod 32, and its end extends into the arc-shaped drive groove 45 opened in the swing base plate 42. When the L-shaped drive arm 36 performs a circular rotation, its end slides back and forth in the arc-shaped drive groove 45, forcing the swing base plate 42 to swing back and forth at high frequency around the hinge connecting it to the top of the gripping plate 40 through a pushing and pulling action. An H-shaped arc-shaped cleaning seat 43 is fixed on the top of the swing base plate 42. The blower nozzles 44 evenly arranged at the bottom of both ends of the arc-shaped cleaning seat 43 sweep back and forth along the arc path on both sides of the top of the material.

[0029] Meanwhile, the oscillating lifting motion of the moving plate 26 drives the piston rod 52 to move up and down within the blower 50. When the moving plate 26 descends, the piston plate 51 moves downward, creating a negative pressure inside the blower 50, drawing in air from the air inlet pipe 54 to complete the charging and energy storage. When the moving plate 26 rises, the piston plate 51 moves upward and compresses the air. The high-pressure gas flows through the air outlet pipe 53 into the inner cavity of the arc-shaped cleaning seat 43, and is finally ejected at high speed from the oscillating blower nozzle 44. Because the blower nozzle 44 continuously changes the spray angle and position while spraying air, the high-speed airflow forms a dynamic air curtain that sweeps across from one edge of the material's surface to the other edge, and then sweeps back in the opposite direction, repeating this cycle continuously. The oscillating airflow method causes the grooves, steps, and areas around screw holes on the material surface, which are prone to dust accumulation, to be repeatedly impacted by airflow from different directions. Impurities are stripped off by multi-angle shearing forces and quickly swept away from the material area by the turbulent airflow. This avoids the cleaning dead corners and secondary deposition problems that may exist with fixed-direction airflow, significantly improving the cleaning uniformity and thoroughness of the material surface, and providing a clean and unobstructed imaging surface for subsequent visual inspection.

[0030] See Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8A U-shaped base plate 70 is fixedly installed at the bottom of the frame 10. A wrapping detection assembly is installed on the top of the U-shaped base plate 70 to detect the wrapping motion of the material from the outside. The wrapping detection assembly includes a cross-shaped fixing frame 60, a support plate 68, and an equipment plate 67. The support plate 68 moves horizontally within the cross-shaped fixing frame 60, and the equipment plate 67 moves vertically within the cross-shaped fixing frame 60. Cross-shaped fixing frames 60 are fixedly installed at both ends of the top of the U-shaped base plate 70. A first slider 61 is slidably connected to the cross-shaped fixing frame 60 in the horizontal direction, and a second slider 62 is slidably connected to the cross-shaped fixing frame 60 in the vertical direction. The wrapping detection assembly also includes a fixed gear 66 and a movable gear 64. A base plate 65 is fixedly installed at both ends of the top of the U-shaped base plate 70. A connecting plate 63 is movably connected between the first slider 61 and the second slider 62 via a rotating shaft. A movable gear 64 is provided at the center of the connecting plate 63. A fixed gear 66 is connected to the top of the base plate 65 via a rotating shaft. The movable gear 64 and the fixed gear 66 are movably meshed. A first pulley 74 is fixedly installed on the rotating shaft of the movable gear 64. A rotary motor 71 is fixedly installed on the top of the U-shaped base plate 70. A drive rod 72 is fixedly installed at the output end of the rotary motor 71. Second pulleys 73 are fixedly installed at both ends of the drive rod 72. A transmission belt 75 is connected between the first pulley 74 and the second pulley 73.

[0031] A support plate 68 is fixedly installed between the first sliders 61, and an equipment plate 67 is fixedly installed between the second sliders 62. The support plate 68 is made of transparent material. The support plate 68 places the material under the fixed suction cup 41. Several vision cameras 69 are staggered on the equipment plate 67. The staggered vision cameras 69 detect the material on the support plate 68 from both the top and bottom.

[0032] See Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 After the rotary motor 71 starts, its output end drives the drive rod 72 to rotate continuously around its own axis, and the second pulleys 73 at both ends of the drive rod 72 rotate synchronously. The rotational power is transmitted through the transmission belt 75 to the first pulley 74 at the shaft of the movable gear 64 on the base plate 65, forcing the first pulley 74 to drive the movable gear 64 to rotate together. The movable gear 64 and the fixed gear 66 always maintain a meshing relationship. The rotational motion of the movable gear 64 drives the fixed gear 66 to rotate, and the rotation of the fixed gear 66 is deflected and oscillated through the connecting plate 63 connected to its shaft. The two ends of the connecting plate 63 are movably connected to the first slider 61 and the second slider 62 through the shaft, respectively. When the connecting plate 63 oscillates, one end pushes the first slider 61 to slide back and forth along the horizontal slide rail of the cross fixed frame 60, and the other end simultaneously pushes the second slider 62 to move up and down along the vertical slide rail of the cross fixed frame 60. The movement directions of the two sets of sliders are perpendicular to each other and are linked synchronously.

[0033] As the second slider 62 rises vertically, the device plate 67 and the vision camera mounted on it rise accordingly. Simultaneously, the first slider 61 moves the support plate 68 horizontally from one end of the cross-shaped fixing frame 60 to the other. Multiple vision cameras 69, arranged in an alternating pattern on the device plate 67, follow the vertical rise and fall, traversing from one edge to the other above the material, coordinating with the horizontal movement of the material itself to form an oblique scanning trajectory from bottom to top and from one end to the other. When the second slider 62 reaches its top and begins its descent, the device plate 67 moves the vision cameras 69 vertically back down, while the first slider 61 moves the support plate 68 horizontally back in the opposite direction. The vision cameras 69 then traverse horizontally again from above the material, forming an oblique scanning trajectory from top to bottom and returning to the starting side from the other side. These two sets of oblique scans in opposite directions intertwine, creating a three-dimensional, wraparound motion network around the material on both sides of the image path of the vision cameras 69.

[0034] Because the support plate 68 is made of transparent material, the vision camera 69 can not only image the upper surface of the material from above, but the cameras arranged below it can also simultaneously acquire images of the lower surface of the material through the support plate 68. The staggered vision cameras 69, while following the horizontal reciprocating motion of the equipment plate 67, continuously capture images of the material from different heights and horizontal positions, ensuring that every surface area of ​​the material is covered by multiple, multi-angle views. This surround motion detection method effectively eliminates blind spots and occlusion problems inherent in fixed-viewpoint detection. Whether it's depressions, protrusions, or chamfered edges on the material surface, all can be clearly captured during dynamic scanning, providing comprehensive and accurate image data support for subsequent component analysis and defect identification.

[0035] See Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 A U-shaped support plate 80 is fixedly installed at the top center of the U-shaped base plate 70. A reciprocating rod 82 is movably inserted through the U-shaped support plate 80. Fill lights 83 are fixedly installed at both ends of the reciprocating rod 82. A rotating cylinder 81 is fixedly installed at the center of the drive rod 72. An annular actuation groove 84 is opened on the outer periphery of the rotating cylinder 81. The motion fill light assembly also includes a T-shaped actuation rod 85. One end of the T-shaped actuation rod 85 is movably fitted in the annular actuation groove 84, and the other end is fixedly connected to the reciprocating rod 82.

[0036] See Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8When the drive rod 72 rotates continuously under the drive of the rotary motor 71, the rotating cylinder 81 fixed at its center rotates synchronously. A T-shaped actuating rod 85 is movably fitted inside the annular actuating groove 84. One end of the T-shaped actuating rod 85 is embedded in the groove, and the other end is fixedly connected to the reciprocating rod 82 that passes through the U-shaped support plate 80. When the rotating cylinder 81 rotates, the curved trajectory of the annular actuating groove 84 forces the T-shaped actuating rod 85 to produce periodic displacement along the groove, thereby converting the circular motion of the rotating cylinder 81 into the horizontal linear reciprocating motion of the reciprocating rod 82. The supplementary lights 83, which are fixedly installed at both ends of the reciprocating rod 82, move back and forth horizontally on one side of the bottom of the support plate 68. The luminous surface of the supplementary lights 83 always faces the bottom of the material on the transparent support plate 68.

[0037] While the package inspection component drives the vision camera 69 to perform a surround scan, the supplementary light 83 moves back and forth beneath the support plate 68 at a frequency synchronized with the inspection rhythm. Light penetrates the transparent support plate 68 from the moving light source position and illuminates the lower surface of the material. The continuous change in the light source position ensures that different areas on the bottom of the material are illuminated by light at different angles, effectively eliminating shadows caused by the material's own structure when using fixed light source illumination. The horizontal reciprocating motion of the supplementary light 83 covers the full width of the support plate 68, ensuring that the bottom of the material is evenly covered by light regardless of its position on the support plate 68. This dynamic supplementary lighting method, combined with the surround motion of the vision camera 69, ensures that the upper and lower surfaces of the material maintain consistent brightness and clear contrast throughout the image acquisition process, providing high-quality lighting conditions for subsequent component identification and defect determination.

[0038] Working principle: After the equipment starts, the conveyor roller 11 rotates continuously to transport the material from the compressor component forward; when the material reaches directly below the identification frame 12, the material lifting and cleaning component starts to operate; the output shaft of the servo motor 31 rotates, driving the second bevel gear 34 to rotate, and the second bevel gear 34 meshes with and drives the first bevel gear 33 to rotate, thereby causing the connecting rod 32 to rotate inside the support cylinder 30; one end of the connecting rod 32 passes through the motion plate 26 and is fixed to the motion gear 35, and the motion gear 35 is fixed to the feeding side plate 20. The outer circumferential teeth of the toothed column 28 mesh, and while rotating, it is forced to roll along the toothed column 28, generating a revolution motion around the toothed column 28; this is transmitted to the moving plate 26 through the connecting rod 32, forcing the moving plate 26 and the fixed sliders 25 on both sides to generate a loop trajectory motion within the fixed slide groove 24 of the loop motion frame 23; the moving plate 26 then descends and rises in the vertical direction, and simultaneously translates in the horizontal direction; the gripping plate 40 at the bottom of the moving plate 26 then performs the periodic actions of descending, gripping, lifting, and translating.

[0039] Specifically, firstly, when the moving gear 35 rolls along the toothed post 28, it drives the moving plate 26 to perform the first downward movement along the fixed slide 24 in the loop motion frame 23; the moving plate 26 moves vertically downward, driving the gripping plate 40 and the fixed suction cup 41 to descend above the material on the surface of the conveyor roller 11. The fixed suction cup 41 is energized to form a negative pressure, adsorbing and gripping the material; after gripping, the moving plate 26 immediately performs an upward movement, driving the material to detach from the conveyor roller 11; next, the moving plate 26 performs a horizontal translation movement under the constraint of the loop slide, moving the adsorbed material laterally from directly above the conveyor roller 11 to directly above the transparent support plate 68; at this time, the moving plate 26 pauses its horizontal movement and performs the second downward movement, that is, moves vertically downward, placing the material onto the surface of the support plate 68; after the material smoothly contacts the support plate 68, the fixed suction cup 41 is de-energized to release the vacuum, releasing the material and completing the placement action; finally, the moving plate 26 performs an upward reset movement, returning to the starting position above the conveyor roller 11 without load, ready for the next cycle of gripping.

[0040] The two downward movements of the motion plate 26 have a clear purpose: the first downward movement is used to grab the material to be inspected on the conveyor roller 11, and the second downward movement is used to place the material on the bearing plate 68 of the inspection station; the two downward movements are connected and transitioned by the upward movement and the horizontal translation movement to form a complete loop pick-and-place trajectory.

[0041] When the moving plate 26 performs its first vertical descent, the piston rod 52 at the top of the moving plate 26 drives the piston plate 51 inside the blower 50 to move downward. The volume of the cavity above the piston plate 51 expands, creating a negative pressure. External air is drawn into the cavity through the air inlet pipe 54 and the one-way valve to complete the inflation and energy storage. At this time, the fixed suction cup 41 is energized to grab the material on the surface of the conveyor roller 11 by vacuum adsorption. The blower nozzle 44 has no airflow output to ensure that the material position is stable at the moment of grabbing. Immediately afterwards, the moving plate 26 performs an upward movement, causing the material to detach from the conveyor roller 11. The piston rod 52 pushes the piston plate 51 upward with the upward movement, compressing the volume of the cavity above the piston plate 51 and increasing the internal air pressure. The high-pressure gas pushes open the one-way valve of the air outlet pipe 53 and rushes into the inner cavity of the arc-shaped cleaning seat 43.

[0042] Meanwhile, the continuous rotation of the connecting rod 32 drives the L-shaped drive arm 36 fixed at its end to rotate in a circular motion. The end of the L-shaped drive arm 36 slides back and forth in the arc-shaped drive groove 45 opened in the swing base plate 42. Through the pushing and pulling action, the swing base plate 42 is forced to swing back and forth around the hinge point at the top of the gripping plate 40. The arc-shaped cleaning seat 43 and the blower nozzle 44 at the bottom sweep back and forth along the arc path on both sides of the top of the material. The high-pressure airflow is ejected at high speed from the blower nozzle 44, which constantly changes the spray angle and spatial position, forming a horizontally moving oscillating air curtain. It repeatedly sweeps across the upper surface of the material with a variable impact direction, and performs a thorough cleaning of the edges, grooves and screw holes without dead angles, completely peeling off the attached impurities and rolling them away from the material area.

[0043] After the upward cleaning is completed, the moving plate 26 enters the horizontal translation stage, while the vertical position remains unchanged. The piston plate 51 remains stationary inside the blower 50, and the airflow output is paused. The material is smoothly transferred to the top of the transparent support plate 68. Subsequently, the moving plate 26 performs a second vertical downward movement, placing the material onto the surface of the support plate 68. During the descent, the piston plate 51 moves downward again, and the blower 50 draws in air a second time to complete the inflation. At this time, the blower nozzle 44 is dry to avoid airflow interfering with the material placement accuracy. After the material contacts the support plate 68 and the fixed suction cup 41 is de-energized and released, the moving plate 26 performs a second upward reset movement. The piston plate 51 then moves upward again to compress air, and the high-pressure airflow is sent into the arc-shaped cleaning seat 43 a second time. The blower nozzle 44 continues to oscillate at a high frequency under the continuous drive of the L-shaped drive arm 36, performing a second round of sweeping blower cleaning on the upper surface of the material that has been placed flat on the support plate 68, further removing any trace amounts of dust that may have fallen during the material release process.

[0044] Throughout the entire grabbing and feeding process, the precise coordination of two descents for air intake and two descents for air blowing in the loop trajectory, along with the reciprocating oscillation of the blower nozzles throughout the entire process, achieves a dual cleaning effect of powerful dynamic cleaning of the material after grabbing and after unloading, ensuring that the material surface reaches a high cleanliness imaging standard before entering the visual surround detection.

[0045] Once the material is stably placed on the surface of the transparent support plate 68, the packaging detection component is activated. The output shaft of the rotary motor 71 begins to rotate, driving the rotating rod 72 to rotate continuously around its own axis. The second pulleys 73 at both ends of the driving rod 72 rotate synchronously and transmit the rotational power to the first pulley 74 at the shaft of the movable gear 64 on the base plate 65 through the transmission belt 75, forcing the first pulley 74 to drive the movable gear 64 to rotate together. The movable gear 64 and the fixed gear 66 remain meshed, and the rotational motion of the movable gear 64 is thus converted into the rotation of the fixed gear 66. Since the rotation axis of the fixed gear 66 is connected to the shaft at one end of the connecting plate 63, the connecting plate 63 deflects with the rotation of the fixed gear 66, and then transmits the power to the first slider 61 and the second slider 62 through its other shaft, driving the first slider 61 and the second slider 62 to produce coordinated reciprocating sliding within the slide rail of the cross-shaped fixing frame 60.

[0046] Specifically, when the fixed gear 66 rotates and drives the connecting plate 63 to swing, the second slider 62 is pushed vertically along the cross-shaped fixing frame 60 and begins to move upward along the vertical slide rail. At the same time, the linkage effect of the connecting plate 63 forces the first slider 61 to move synchronously along the horizontal slide rail of the cross-shaped fixing frame 60, causing the material on the bearing plate 68 to move horizontally from one end of the cross-shaped fixing frame 60 to the other end. During this stage, the equipment plate 67 rises vertically along with the second slider 62. As the vertical height gradually increases, the vision camera 69 will move horizontally across the material, from one edge of the material to the other edge, completing a diagonal scanning trajectory from bottom to top and from one end to the other. When the second slider 62 rises to the limit position at the top of the vertical slide rail, the fixed gear 66 continues to rotate, the deflection direction of the connecting plate 63 changes, and the second slider 62 then turns to descend from top to bottom; in conjunction with this, the first slider 61 drives the bearing plate 68 to move in the opposite direction in the horizontal direction, returning horizontally from the other end it just reached to the starting end; at this time, the equipment plate 67 drives the vision camera 69 to descend vertically, and during the horizontal reverse movement of the material, the vision camera 69 crosses over the material again, forming an oblique scanning trajectory from top to bottom and from the other side back to the starting side; the two sets of oblique scans in opposite directions intersect each other, so that the shooting path of the vision camera 69 weaves a wrap-around motion network on both sides of the material; As the rotary motor 71 continues to operate, the first slider 61 simultaneously completes one horizontal reciprocating motion for each up-and-down reciprocating motion of the second slider 62. The vision camera 69 on the equipment plate 67 then undergoes a complete vertical lifting cycle, while the support plate 68 performs two horizontal scans of the material in opposite directions. The multiple vision cameras 69, arranged in an alternating pattern, follow the movement of the equipment plate 67 and continuously acquire images of the upper and lower surfaces of the material from different heights and angles, thereby forming an all-round, blind-spot-free surround detection coverage around the material, ensuring that the compositional characteristics and surface defects of each side of the material are clearly captured.

[0047] While the vision camera 69 performs surround detection, the motion supplementary lighting component operates synchronously. The rotating cylinder 81 at the center of the drive rod 72 rotates together with the drive rod 72. The annular actuation groove 84 on the outer periphery of the rotating cylinder 81 forces the T-shaped actuation rod 85 inside the groove to move along a curved trajectory. The T-shaped actuation rod 85 converts the rotational motion of the rotating cylinder 81 into the linear reciprocating movement of the reciprocating rod 82. The supplementary lights 83 fixed at both ends of the reciprocating rod 82 then perform horizontal reciprocating motion at the bottom of the support plate 68. The light penetrates the transparent support plate 68 and illuminates the bottom of the material, providing uniform moving supplementary lighting for the vision camera 69, eliminating shadows and ensuring image clarity. Thus, the entire equipment completes the fully automated operation from material conveying, power-on adsorption and gripping, swinging and blowing cleaning, surround vision detection and synchronous motion supplementary lighting.

[0048] Thus, the entire equipment has completed the fully automated operation of the entire process, from material conveying, electrostatic adsorption and grasping, swing purging and cleaning, surround vision detection and synchronous motion supplementary lighting. This fully automated operation mode closely matches the new inspection requirements of compressor components under the background of material iteration: for the characteristics of new materials such as ductile iron, alloy cast aluminum, duplex stainless steel and fiber reinforced composite materials with different surface characteristics and easy to produce pores, sand holes or interlayer defects, the equipment uses the combined effect of loop trajectory pickup and placement and dynamic swing air curtain to ensure that materials with different densities and different surface states reach the high cleanliness imaging standard before inspection; the surround wrapping three-dimensional scanning trajectory, combined with multi-camera staggered framing and dynamic supplementary lighting, eliminates the detection blind spots and shadow areas caused by the complex structural contours of new materials, so that material identification, surface cracks and casting defects can be imaged in all directions without omission; the entire set of operation data and process records are complete and traceable, meeting the strict requirements of downstream OEMs for the consistency of compressor component quality, and also providing accurate and compliant technical basis for the audit and supervision of third-party certification and accreditation bodies, thereby building a full-process guarantee system for the quality reliability of compressor components in the process of transitioning from traditional materials to high-performance new materials.
