Description

Technical Field

[0001] This invention relates to the field of impeller testing equipment, specifically to an automated online testing device for the entire process of pump impeller testing. Background Technology

[0002] With the development of industrial technology, pump impellers, as core components of various pump products, directly affect the performance, efficiency, and service life of the pump. Pump impellers typically have complex three-dimensional geometries, with large variations in blade curvature, and extremely high requirements for dimensional accuracy, shape accuracy, and balance performance. In the modern pump manufacturing field, the testing of pump impellers is of paramount importance.

[0003] Currently, common impeller inspection methods are mainly divided into two categories. One is the traditional manual inspection method, where workers use simple tools such as feeler gauges and calipers to measure the dimensions of each impeller individually, while simultaneously inspecting the impeller's appearance and internal defects through visual inspection or simple tapping. This method is not only inefficient but also susceptible to human error, making it difficult to guarantee accuracy. The other category is semi-automated inspection equipment. This type of equipment can complete some inspection processes but still requires manual operation such as loading and positioning. For example, some impeller dynamic balancing testing equipment requires manual installation of the impeller onto the testing device before the equipment automatically completes the dynamic balance measurement and correction. However, this semi-automated equipment involves significant human intervention during the inspection process, resulting in limited efficiency and making it difficult to meet the requirements of fully automated impeller inspection in large-scale production.

[0004] To address these issues, those skilled in the art have proposed an automated online testing device for the entire process of pump impeller manufacturing. Summary of the Invention

[0012] Preferably, the outer sides of the plurality of drive gears are meshed with the outer side of the rack plate, and the lower surface of the correction plate is slidably connected to the upper surface of the conveyor belt.

[0013] Preferably, the clamping plate is configured with an arc surface, and a rubber pad is provided on the inner side of the clamping plate.

[0014] Preferably, a control panel is installed on the top front side of the test bench, and a detection component is installed on the top rear side of the test bench. The detection component is used to detect the impeller on the electric turntable, and the test bench is controlled by a detection system.

This invention automates the entire impeller process, from conveying, clamping, inspection, and fixing to unloading, significantly improving the efficiency and accuracy of impeller inspection. In the clamping and fixing stage, a combination of a drive screw, double-sided toothed plate, and clamping plate ensures the impeller remains highly stable during inspection, effectively avoiding inspection errors caused by unstable clamping. Furthermore, by optimizing the connection between each process, this equipment shortens the inspection cycle of a single impeller, thereby improving overall production efficiency.

[0017] 2. This invention utilizes the interplay between a rack plate, a bidirectional threaded rod, and a drive gear to precisely correct the impeller's alignment on the conveyor belt.

This not only significantly improves the accuracy and efficiency of impeller detection but also effectively reduces subjective errors associated with manual inspection. Attached Figure Description

[0021] The technical solutions in 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.

[0022] Please see the appendix Figure 1 -Appendix Figure 7This invention provides an automated online testing device for pump impellers, comprising a test bench 1, a feeding robotic arm 2, and a conveyor belt 3. An electric turntable 501 is mounted on one side of the top of the test bench 1. Multiple fixed cylinders 502 are equidistantly fixed to the top of the electric turntable 501. A drive motor 503 is mounted on the outer side of each fixed cylinder 502. A drive screw 504 is fixedly connected to the output end of the drive motor 503. A double-sided toothed plate 505 is threaded onto the outer side of the drive screw 504. Two drive gears 507 are movably connected to the inner side of each fixed cylinder 502 via bearings. A connecting rod 508 is fixedly connected to the outer side of each drive gear 507. Two connecting rods 509 are hinged to the outer side of each fixed cylinder 502. A clamping plate 506 is rotatably mounted at the end of each connecting rod 509. The feeding robotic arm 2 is used to feed the tested impellers from the electric turntable 501. The conveyor belt 3 is located above the test bench 1 and is used to transport the impellers. The clamping plate 506 is designed with an arc surface, and a rubber pad is provided on the inner side of the clamping plate 506.

[0023] Specifically, the test bench 1 serves as the base of the entire equipment, providing an installation platform and support for other components, ensuring the overall stability and rigidity of the equipment. The unloading robotic arm 2 is used to remove the inspected impellers from the electric turntable 501 and perform unloading operations, achieving automated processing and improving production efficiency. The conveyor belt 3 is located above the test bench 1, its main function being to transport the impellers to be inspected to designated positions for subsequent inspection operations. The electric turntable 501 is installed on one side of the top of the test bench 1, used to place and rotate the impellers, allowing them to sequentially enter different inspection stations for multi-angle and omnidirectional inspection. The clamping plate 506 is designed with an arc surface and rubber pads on its inner side. The arc surface design allows the clamping plate 506 to better fit the outer circumference of the impeller, increasing the contact area and improving clamping stability. The rubber pads prevent the clamping plate 506 from damaging the impeller surface, protecting the impeller's appearance quality. When the drive motor 503 starts, it drives the drive screw 504 to rotate. The drive screw 504 drives the double-sided gear plate 505 to move, which in turn drives the drive gear 507 to rotate. The drive gear 507, through the cooperation of the connecting rod 508 and the connecting rod 509, drives the clamping plate 506 to clamp the impeller, achieving a stable fixation of the impeller and ensuring that the impeller remains highly stable during the testing process, avoiding testing errors caused by unstable clamping.

[0024] A rotating disk 701 is fixedly connected to the end of the drive roller inside the conveyor belt 3. A fixed block 702 is fixedly connected to the eccentric part of the rotating disk 701. A movable plate 703 is slidably connected to the outer surface of the rotating disk 701. A connecting strip 704 is fixedly connected to the outer side of the movable plate 703. A rack plate 801 is slidably installed on the outer side of the unloading robotic arm 2. Multiple bidirectional threaded rods 802 are movably connected to the inner side of the unloading robotic arm 2 through bearings. Two threaded brackets 804 are threadedly connected to the outer side of the bidirectional threaded rods 802. A correction plate 806 is connected to the outer side of the threaded brackets 804 through a connecting rod 805. A drive gear 803 is also fixedly connected to the outer side of the bidirectional threaded rods 802. A movable groove is opened inside the movable plate 703. The fixed block 702 is movably disposed inside the movable groove. The outer side of the movable plate 703 is fixedly connected to the end of the connecting strip 704. The outer sides of multiple drive gears 803 are meshed with the outer side of rack plate 801, and the lower surface of correction plate 806 is slidably connected to the upper surface of conveyor belt 3.

[0025] Specifically, the rotating disk 701 is driven by the drive roller to rotate, transmitting power for subsequent movements. The fixed block 702 rotates eccentrically with the rotating disk 701, driving the movable plate 703 to move. Multiple impellers to be inspected are placed on the conveyor belt 3. After startup, the drive roller drives the rotating disk 701 to rotate, the fixed block 702 rotates eccentrically, driving the movable plate 703 to reciprocate left and right. This, via the connecting strip 704, drives the rack plate 801 to move left and right, which in turn causes the drive gear 803 to oscillate back and forth, driving the bidirectional threaded rod 802 to rotate in both directions. Under the action of the bidirectional threaded rod 802, the threaded frame 804 moves closer or further away from each other, and the correction plate 806 moves synchronously, precisely correcting the impellers on the conveyor belt 3 to ensure the correct posture and position during conveying.

[0026] A mounting bracket 601 is fixedly connected to one side of the top of the test bench 1. An electric slide rail 603 is installed on the outside of the mounting bracket 601. An mounting plate 604 is installed on the outside of the electric slide rail 603 via an electric slider. An electric telescopic rod 602 is installed on the top of the mounting plate 604. A support base 605 is fixedly connected to the telescopic end of the electric telescopic rod 602. A clamping cylinder 606 is installed at the bottom of the support base 605.

[0027] Specifically, the electric slide rail 603, in conjunction with the electric slider, provides a precise linear guide for the mounting plate 604, ensuring its smooth lateral movement. The mounting plate 604 serves as a support platform, supporting components such as the electric telescopic rod 602 and ensuring its stable operation. The electric telescopic rod 602 provides vertical driving force, causing the support base 605 and the clamping cylinder 606 to move up and down. The support base 605 connects the electric telescopic rod 602 and the clamping cylinder 606, ensuring the stable operation of the clamping cylinder 606. The clamping cylinder 606 utilizes air pressure to generate clamping force, precisely gripping and releasing the impeller.

[0028] When the impeller reaches the predetermined position on the mounting bracket 601, the mounting plate 604, with the close cooperation of the electric slide rail 603 and the electric slider, can be flexibly adjusted to the optimal position. Subsequently, the electric telescopic rod 602 is activated, pushing the support base 605 and the clamping cylinder 606 to move down synchronously. At this time, the clamping cylinder 606 accurately grasps the impeller on the conveyor belt 3 and places it steadily on the electric turntable 501, preparing for the subsequent inspection process.

[0029] The end of the drive screw 504 away from the drive motor 503 is movably connected to the inner wall of the fixed cylinder 502 via a bearing. The outer sides of the two drive gears 507 are meshed with the outer sides of the double-sided toothed plate 505. The end of the connecting rod 508 away from the drive gears 507 is rotatably connected to the outer side of the clamping plate 506.

[0030] Specifically, when the drive motor 503 is working, the drive screw 504 rotates, causing the double-sided toothed plate 505 to move, which in turn drives the two drive gears 507 to rotate. Through the transmission of the connecting rod 508, the clamping plate 506 finally clamps the impeller, ensuring that the impeller remains highly stable during the testing process and avoiding testing errors caused by unstable clamping. Each component works closely together to form a highly efficient impeller clamping structure.

[0031] A control panel 4 is installed on the top front side of the test bench 1, and a detection component 9 is installed on the top rear side of the test bench 1. The detection component 9 is used to detect the impeller on the electric turntable 501. The test bench 1 is controlled by the detection system.

[0032] Specifically, the main function of the detection component 9 is to detect the impeller placed on the electric turntable 501. After the impeller is gripped by the clamping cylinder 606 and placed on the electric turntable 501, the electric turntable 501 will rotate the impeller to the detection position of the detection component 9. The detection component 9 can accurately measure and detect various performance indicators and parameters of the impeller, and the control panel 4 is used for centralized control and operation of the detection equipment.

[0033] The detection system includes: The 3D laser scanning module uses a laser emitter to project a laser beam onto the impeller surface. After the laser beam is reflected by the impeller surface, the laser receiver captures the reflected light signal. Based on information such as the phase difference and time difference of the reflected light, the module calculates the three-dimensional coordinate data of each point on the impeller surface, thereby measuring the geometric dimensions of the impeller. The deep learning algorithm module analyzes the preprocessed images and 3D model data, extracts key features through model training, and accurately determines whether there are defects in the impeller. Specifically, the deep learning algorithm module is the core of the impeller inspection equipment. It is responsible for analyzing the preprocessed images and 3D model data, extracting key features through model training, and accurately determining whether there are defects in the impeller.

[0034] The preprocessed data is trained using a convolutional neural network, and its operating formula is as follows:

[0035] in: It is the input image or feature map. It is a convolution kernel. It is the location of the output feature map.

[0036] The intelligent feedback optimization module dynamically adjusts the detection parameters and processes based on big data processing results and real-time feedback information from the detection system using an adaptive control algorithm.

[0037] Specifically, this module first collects and integrates the results of big data processing and information fed back from the detection system during real-time operation. Through comprehensive analysis of this data, it identifies potential problems and optimization points in the impeller detection process. Based on the analysis results, the module uses an adaptive control algorithm to dynamically adjust the detection parameters and process to ensure the accuracy and efficiency of the detection. If real-time data indicates that the error in a certain detection step exceeds a set threshold, the intelligent feedback optimization module will automatically adjust relevant detection parameters, such as sensitivity and detection angle, to reduce errors and improve detection quality. Simultaneously, it can also predict potential defect trends based on the impeller's real-time detection data, proactively optimize the detection process, reduce unnecessary detection steps, and thus improve overall detection efficiency.

[0038] Working principle: When using this device, its operating principle includes the following: Multiple impellers to be tested are placed on conveyor belt 3 for transport. When conveyor belt 3 starts, its internal drive roller drives the rotating disk 701 to rotate, and the fixed block 702 rotates eccentrically with the rotating disk 701. Since the fixed block 702 is set in the movable groove inside the movable plate 703, the movable plate 703 moves back and forth under the drive of the fixed block 702, which in turn drives the rack plate 801 to move back and forth through the connecting strip 704. The rack plate 801 drives multiple drive gears 803 to swing back and forth, driving the bidirectional threaded rod 802 to rotate in both directions. The two threaded brackets 804 on the bidirectional threaded rod 802 move closer or further away from each other under its drive, thereby causing the correction plate 806 to move synchronously, performing precise correction processing on the impellers on conveyor belt 3, ensuring that the impellers maintain the correct posture and position during transport.

[0039] When the impeller moves below the mounting bracket 601, the mounting plate 604 moves to the appropriate position with the cooperation of the electric slide rail 603 and the electric slider. The electric telescopic rod 602 is activated, driving the support base 605 and the clamping cylinder 606 to move downwards. The clamping cylinder 606 grips the impeller on the conveyor belt 3 and places the gripped impeller on the electric turntable 501. At this time, the drive motor 503 drives the drive screw 504 to rotate, which in turn drives the double-sided toothed plate 505 to move, thereby driving the drive gear 507 to rotate. The drive gear 507, through the cooperation of the connecting rod 508 and the connecting rod 509, drives the clamping plate 506 to clamp the impeller, achieving a stable fixation of the impeller and ensuring that the impeller remains highly stable during the inspection process, avoiding inspection errors caused by unstable clamping.

[0040] After the impeller is fixed, the electric turntable 501 rotates at a certain angle, sequentially sending the impellers into the inspection station. The inspection component 9, controlled by the control panel 4, starts to perform multi-directional, high-precision inspection of the impeller. The inspection system includes a 3D laser scanning module, a deep learning algorithm module, and an intelligent feedback optimization module. The 3D laser scanning module projects a laser beam onto the impeller surface using a laser emitter. After reflection from the impeller surface, the laser beam is captured by a laser receiver. Based on the phase difference, time difference, and other information of the reflected light, the three-dimensional coordinate data of each point on the impeller surface is calculated, thereby measuring the impeller's geometric dimensions. The deep learning algorithm module analyzes the pre-processed images and 3D model data, extracts key features through model training, and accurately determines whether the impeller has defects. The intelligent feedback optimization module dynamically adjusts the inspection parameters and process using an adaptive control algorithm based on the big data processing results and real-time feedback information from the inspection system, ensuring the accuracy and reliability of the inspection results.

[0041] After the inspection is completed, the unloading robotic arm 2 is started. The rack plate 801, which is slidably mounted on its outer side, moves under the drive of the second drive gear 803, so that the unloading robotic arm 2 is adjusted to a suitable position. The unloading robotic arm 2 picks up the impeller after the inspection is completed from the electric turntable 501 and places it in the corresponding unloading position according to the inspection results, thus completing the unloading process of the impeller.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
