Description

Technical Field

[0001] This utility model relates to the field of flange testing technology, and in particular to a rapid flange grading and screening machine. Background Technology

[0002] This invention addresses the problem of low efficiency and error-proneness in existing flange sorting methods that rely on manual operation, by proposing a rapid flange grading and sorting machine. The equipment integrates automated detection, grading, and marking functions, significantly improving the efficiency and accuracy of flange sorting while reducing manual intervention. Utility Model Content

[0003] The purpose of this utility model is to provide a rapid flange grading and screening machine that solves the problems mentioned in the background art.

[0004] The system includes a flange feeder and a grading and testing main unit. The flange feeder consists of a speed-regulating motor, a chain tensioning mechanism, a drive sprocket, a driven sprocket, a rotating shaft, a slewing bearing, a turntable, an arranging mechanism, a discharge channel, and a turntable cover. The speed-regulating motor drives the turntable to rotate clockwise via a sprocket drive, using centrifugal force to arrange the flanges to the outer circumference of the turntable, and then they enter the high-speed belt conveyor of the grading and testing main unit through the discharge channel. The width of the discharge channel can be adjusted by an adjustment mechanism to accommodate the production needs of flanges with different outer diameters. The arranging mechanism ensures that the flanges are neatly arranged in a row within the discharge channel, avoiding chaotic accumulation. The turntable cover is installed on the outside of the turntable to protect the operator's safety and prevent flanges from flying out and causing injury.

[0005] Furthermore, the graded inspection host has a U-shaped structure, including a frame, a fast feeding conveyor belt, a fast unloading conveyor belt, a sorting mechanism, a model inspection vision system, a defect inspection vision system, a height measurement station, an engraving station, and an unloading mechanism. The sorting mechanism is installed on the feeding conveyor belt to achieve orderly sorting of flanges. The model inspection vision system and the defect inspection vision system perform model matching inspection and surface defect inspection on the flanges, respectively. If the inspection result is unqualified, the unloading cylinder pushes the flange out of the conveyor belt and it slides into the NG receiving frame of the vision system.

[0006] Specifically, the height measurement station includes a hand-cranked slide table, a digital display for the slide table, a handwheel, a slide table base, and a contact displacement sensor. The hand-cranked slide table adjusts the height of the slide table base via the handwheel, and the digital display shows the Z-axis height to accommodate flanges of different heights. The contact displacement sensor is mounted on the slide table base with a center pitch circle, measures the flange thickness, and outputs data. The height measurement station calculates the flange thickness by averaging three measurements, with each 0.02mm increment representing a graded gradient.

[0007] Furthermore, the marking station integrates a laser marking mechanism to mark qualified flanges. The position of the laser marking mechanism can be adjusted via an adjustment mechanism in the X, Y, and Z axes to accommodate flanges of different sizes. After marking, the flange is pushed onto the unloading conveyor belt by a pusher plate driven by a feeding cylinder. Based on the grading results, the flange is pushed to the grading and receiving box; if the height measurement is unqualified, the flange automatically flows to the height-measuring NG receiving box.

[0008] Specifically, the transfer robot consists of a rodless cylinder, gripper A, gripper B, a robot arm limiting mechanism, and a linear guide rail. The rodless cylinder serves as the transfer power, driving the robot arm to move smoothly along the linear guide rail. Gripper A transfers the flange from the lifting station to the height measurement station, and gripper B transfers the flange from the height measurement station to the marking station. The robot arm limiting mechanism includes a hydraulic damper and a limiting screw, used to adjust the final stop position of the rodless cylinder and reduce the impact caused by high-speed movement.

[0009] Furthermore, the equipment cabinet is embedded inside the lower left corner of the grading and testing host, integrating electrical control components. The touchscreen is fixed to the top of the host via an operation screen slide rail and can move left and right for equipment debugging. The vision display is embedded in the front of the equipment cover, facilitating the debugging of model identification vision and defect identification vision.

[0010] The technical solution of this utility model achieves automated grading and screening of flanges through the following steps: S1, the flange feeding machine conveys the flanges to the grading and testing host; S2, the sorting mechanism sorts the flanges in an orderly manner; S3, the model detection vision and defect detection vision respectively perform model matching detection and surface defect detection on the flanges; S4, the height measurement station accurately measures and grades the flange thickness; S5, the marking station laser marks the qualified flanges; S6, the unloading mechanism pushes the flanges to the corresponding receiving box according to the grading results.

[0011] The beneficial effects of this invention are as follows: The automated arrangement and conveying function of the flange feeder significantly reduces the frequency of manual loading, allowing for the storage of approximately 100 flanges at a time. The industrial vision system reliably distinguishes between flanges of non-designated models and defective flanges, avoiding errors caused by subjective human judgment. The height measurement mechanism achieves high-precision thickness measurement through a precision displacement sensor, with grading accuracy down to 0.02mm. Laser engraving is integrated into the equipment, reducing the time spent on reloading and further improving sorting efficiency. Furthermore, the equipment can be adapted to the production needs of flanges of different models and sizes by changing the contour clamps and adjusting the slide height, offering high flexibility.

[0012] In summary, this utility model provides an efficient, accurate, and flexible flange grading and screening solution, applicable to flange production and testing in fields such as air conditioning compressors. Attached Figure Description

[0020] This utility model provides a rapid flange grading and sorting machine, which significantly improves the efficiency and accuracy of flange sorting through the integrated design of automated detection, grading, and marking functions. The following description, in conjunction with the appendix... Figure 1 To be continued Figure 5 The accompanying drawings, along with the specific component numbers marked in the accompanying drawings, provide a detailed description of the specific embodiments of this utility model.

[0021] This utility model's rapid flange grading and screening machine consists of a flange feeder 1 and a grading and detection host 31. The two work together to automatically arrange, convey, detect, grade, mark, and collect flanges. The core components of the flange feeder 1 include a speed-regulating motor 2, a chain tensioning mechanism 3, a drive sprocket 4, a driven sprocket 5, a rotating shaft 6, a slewing bearing 7, a turntable 8, an arranging mechanism 9, a discharge channel 10, and a turntable cover 11. The speed-regulating motor 2 transmits power to the drive sprocket 4 via chain drive, which in turn drives the driven sprocket 5 to rotate, thereby driving the rotating shaft 6 to rotate. The turntable 8 is fixed on the slewing bearing 7 and connected to the rotating shaft 6. When the turntable 8 rotates clockwise, the flanges move to the outside of the turntable under centrifugal force and enter the discharge channel 10. The arranging mechanism 9 is installed inside the turntable 8 to neatly arrange the flanges in a row, avoiding chaotic accumulation. The width of the discharge channel 10 can be adjusted according to flanges of different outer diameters to adapt to the production needs of various machine models. A turntable guard 11 is installed on the outside of the turntable 8 to protect the operator's safety and prevent the flange from flying off and causing injury. In addition, the turntable 8 has a hollow shaft design at its center, which facilitates the installation of the arrangement mechanism 9 and further improves the flexibility of the equipment.

[0022] The grading and inspection main unit 31 has a U-shaped structure and includes a frame, a fast feeding conveyor belt, a fast unloading conveyor belt, a sorting mechanism 36, a model inspection vision device 37, a defect inspection vision device 38, a height measurement station, an engraving station, and an unloading mechanism. The grading and inspection main unit 31 has an inlet on its right side, connected to the outlet of the flange feeder 1. The fast feeding conveyor belt has an adjustable width to accommodate flanges of different sizes. The sorting mechanism 36 is installed on the feeding conveyor belt and achieves orderly sorting of flanges through alternating blocking. The model inspection vision device 37 and the defect inspection vision device 38 perform model matching inspection and surface defect inspection on the flanges, respectively. If the inspection result is unqualified, the unloading cylinder 40 pushes the flange out of the conveyor belt and onto the NG receiving frame 41. This design ensures that flanges of non-designated models or with surface defects can be promptly rejected, preventing them from being mixed into subsequent processes.

[0023] The height measurement station is a crucial component of the grading and testing main unit 31. Its core components include a hand-cranked slide table 13, a slide table digital display 14, a handwheel 15, a slide table base 16, and a contact displacement sensor 17. The hand-cranked slide table 13 adjusts the height of the slide table base 16 via the handwheel 15, and the slide table digital display 14 displays the Z-axis height in real time to accurately adapt to flanges of different heights. The contact displacement sensor 17 is mounted on the slide table base 16 with a center pitch circle, and its position can be adjusted according to the flange size to meet the measurement requirements of different models. After the flange is transferred to the height measurement station, the contact displacement sensor 17 extends its built-in cylinder, causing the measuring head to contact the flange surface and output thickness data. The system calculates the flange thickness by averaging three measurements and grades it in increments of 0.02 mm. This design not only improves measurement accuracy but also automates the grading process, reducing manual intervention.

[0024] The marking station integrates a laser marking mechanism 39 for marking qualified flanges. The position of the laser marking mechanism 39 can be adjusted via a three-axis adjustment mechanism (X, Y, Z) to accommodate flanges of different sizes. After marking, the flange is pushed onto the unloading conveyor belt by a pusher plate 30 driven by a feeding cylinder 29. Based on the grading results, the flange is pushed to the grading receiving box 43; if the height measurement is unqualified, the flange automatically flows to the height-measuring NG receiving box 42. This design integrates the laser marking function into the equipment, reducing the time for reloading and unloading, and further improving sorting efficiency.

[0025] The transfer robot 18 is a key component of the grading and inspection main unit 31, consisting of a rodless cylinder 19, grippers A20 and B21, a robot arm limiting mechanism 22, and a linear guide rail 23. The rodless cylinder 19 provides the transfer power, driving the robot arm to move smoothly along the linear guide rail 23. Gripper A20 transfers the flange from the lifting station to the height measurement station, and gripper B21 transfers the flange from the height measurement station to the marking station. The robot arm limiting mechanism 22 includes a hydraulic damper and limit screws, used to adjust the final stop position of the rodless cylinder 19, reducing the impact of high-speed movement and ensuring smooth robot arm operation. The design of the linear guide rail 23 increases the overall rigidity of the transfer robot 18, further improving operational stability.

[0026] The equipment cabinet 32 ​​is embedded in the lower left corner of the grading and inspection host 31, integrating electrical control components. The touch screen 33 is fixed to the top of the grading and inspection host 31 via the operation screen slide rail 34, and can move left and right for equipment debugging. The vision display 35 is embedded in the front of the equipment cover, facilitating the debugging of the model identification vision 37 and defect identification vision 38. The right side inlet of the grading and inspection host 31 is connected to the outlet of the flange feeder 1. The front end of the fast conveyor belt for feeding is equipped with a set of baffles, which alternately block the flanges to achieve material separation. After the model identification vision 37 and defect identification vision 38 identify NG (not good), the unloading cylinder 40 pushes the flange out of the conveyor belt and it slides into the NG receiving frame 41. The transfer robot 18 completes the inspection and rotation direction adjustment of the flange in the grading and inspection host 31. The laser marking mechanism 39 is located at the front end of the discharge belt. After the marking is completed, the unloading cylinder 29 drives the pusher plate 30 to push the flange onto the unloading belt. Finally, the unloading cylinder 40 pushes the flange to the grading receiving box 43 or the height measuring NG receiving box 42.

[0027] The operation process of this utility model is as follows: S1, the flange feeder 1 transports the flanges to the grading and testing host 31. The speed-regulating motor 2 drives the turntable 8 to rotate clockwise through the sprocket drive, and uses centrifugal force to arrange the flanges to the outside of the turntable and enter the fast belt conveyor of the grading and testing host 31 through the discharge channel 10. S2, the material distribution mechanism 36 distributes the flanges in an orderly manner to ensure that the flanges enter the testing process one by one. S3, the model inspection vision 37 and the defect inspection vision 38 perform model matching inspection and surface defect inspection on the flanges, respectively. If the inspection result is unqualified, the unloading cylinder 40 pushes the flange out of the belt conveyor and slides it into the vision NG receiving frame 41. S4, the height measurement station accurately measures and grades the flange thickness. The contact displacement sensor 17 extends from the cylinder, so that the measuring head contacts the flange surface and outputs thickness data. The system calculates the flange thickness by taking the average of the three measured values ​​and grades it in increments of 0.02 mm. S5, the marking station laser marks the qualified flanges. The laser engraving mechanism 39 adjusts its position according to the flange size. After engraving, the unloading cylinder 29 drives the pusher plate 30 to push the flange onto the unloading conveyor belt. S6, the unloading mechanism pushes the flange to the corresponding receiving box according to the grading results. Flanges that pass the inspection are pushed to the grading receiving box 43, while flanges that fail the height measurement automatically flow to the height measurement NG receiving box 42.

[0028] This invention significantly reduces the frequency of manual loading through the automated arrangement and conveying function of the flange loading machine 1, which can store approximately 100 flanges at a time. The industrial vision system reliably distinguishes between flanges of non-designated models and defective flanges, avoiding errors caused by subjective human judgment. The height measuring mechanism achieves high-precision thickness measurement through a precision displacement sensor, with grading accuracy down to 0.02mm. Laser engraving is integrated into the equipment, reducing the time spent on reloading and further improving sorting efficiency. Furthermore, the equipment can be adapted to the production needs of flanges of different models and sizes by changing the contour clamps and adjusting the slide height, offering high flexibility.

[0029] In summary, this utility model provides an efficient, accurate, and flexible flange grading and screening solution, applicable to flange production and testing in fields such as air conditioning compressors. Through the detailed description of the above embodiments, those skilled in the art can clearly understand and implement the technical solution of this utility model, thereby achieving automated flange grading and screening.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
