Description

Technical Field

[0001] This utility model relates to the field of vortex stationary disk processing and testing technology, specifically a vortex stationary disk automated testing and engraving integrated machine. Background Technology

[0002] The scroll plate is a key component in air conditioning compressors. The height, flatness, and hole integrity of its machined surface significantly affect its fit with the moving plate and the installation of other parts. Traditional manual inspection methods have many problems in practical applications. For example, when inspecting the height and flatness of the scroll plate's machined surface, operators need to measure point by point, a time-consuming and inefficient process. Furthermore, when checking for missed machined holes, the repeated manual comparison with templates can easily lead to fatigue due to prolonged concentration, resulting in missed or false detections. In addition, the manual recording and input of inspection data not only increases workload but also easily leads to data entry errors or omissions, further reducing the overall reliability and accuracy of the inspection. Therefore, developing a device capable of automated inspection, data acquisition, and classification processing is crucial to solving these problems. This invention aims to improve inspection efficiency and accuracy, reduce errors caused by human factors, and achieve full traceability of product information through an automated integrated inspection and marking device. Utility Model Content

[0003] This invention addresses the problems of cumbersome and inefficient inspection processes and error-prone data recording in existing technologies for vortex plate inspection. It proposes an automated device integrating automatic inspection, laser engraving, QR code reading, and sorting / unloading functions. Through a highly integrated mechanical structure and information management system, the device achieves efficient inspection of the height, flatness, and hole leakage of the vortex plate's machined surface. Furthermore, it assigns a unique identification tag to each product, facilitating full traceability and quality control.

[0004] This invention provides an automated inspection and marking machine for vortex stationary disks, comprising the following components: a frame, which is welded from square tubing and supports all functional modules; a loading module robot arm, driven by a servo motor to move a lead screw on a linear guide rail; a tooling fixture, with an air inspection port, positioning key, and anti-fooling screw on its surface; a laser marking mechanism, installed at the first station and with the marking position adjusted by a three-axis slide table; a QR code reading mechanism, located at the second station and including a QR code reader, a light-shielding cylinder, and a light-shielding plate; a height measurement mechanism, located at the third station and driven by a height-measuring cylinder to perform measurement using six contact displacement sensors; a visual inspection mechanism, located at the fourth station and employing an industrial camera in conjunction with a dual-light source supplementary lighting system; and a unloading robot arm, which sorts and unloads the vortex stationary disks according to the inspection results.

[0005] Furthermore, the equipment is covered with an aluminum profile protective cover. The design of the cover not only enhances safety but also reduces the interference of the external environment on the detection accuracy.

[0006] The loading module robot arm is driven by a servo motor to move a lead screw on a high-precision linear guide, ensuring smooth movement of the fixture in the plane. The fixture surface has three air detection holes connected to a vacuum air detection mechanism to check whether the scroll plate is flat and properly aligned.

[0007] Furthermore, the fixture is equipped with positioning keys and foolproof screws. The positioning keys are used to restrict the placement direction of the scroll plate, while the foolproof screws prevent the scroll plate from being placed incorrectly. The vacuum testing mechanism detects whether the scroll plate is correctly placed by measuring changes in vacuum pressure and displays the results in real time on the industrial control computer monitor.

[0008] The laser engraving mechanism is installed at the first station and consists of a three-axis slide table. The three-axis slide table adjusts the engraving position along the X, Y, and Z axes, respectively. The laser engraving machine engraves a unique code on the surface of the vortex stationary disk, including plain text and QR codes.

[0009] Furthermore, the laser engraving machine controls the engraving parameters through an industrial control computer to ensure that the code of each vortex stationary disk is unique and traceable.

[0010] The QR code reading mechanism is located at the second workstation and includes a QR code reader, a light-shielding cylinder, and a light-shielding plate. The light-shielding cylinder controls the extension and retraction of the light-shielding plate to protect the QR code reader lens from laser reflection when not in operation.

[0011] Furthermore, after the QR code reader scans the QR code on the surface of the vortex stationary disk, it uploads the basic data to the industrial control computer database and displays it on the industrial control computer monitor in real time.

[0012] The height measuring mechanism is located at the third station, where a height measuring cylinder drives six contact displacement sensors to measure height and flatness. A height measuring limit block is located at the end of the height measuring cylinder to ensure that the sensors reach a fixed position during each measurement, thereby guaranteeing repeatability accuracy.

[0013] Furthermore, the six contact displacement sensors correspond to the six measurement points of the vortex stationary disk, and the measurement results are transmitted to the industrial control computer database via signal lines and displayed on the industrial control computer monitor in real time.

[0014] The visual inspection mechanism is located at the fourth station and uses a high-resolution industrial camera in conjunction with a dual-light source illumination system. The industrial camera detects whether there are any missed holes in the vortex stationary disk through a preset template and outputs the number of the missed area.

[0015] Furthermore, the light source system of the vision inspection agency reduces the missed detection rate by adjusting the brightness and angle, and the detection results are uploaded to the industrial control computer database and displayed on the vision monitor in real time.

[0016] The unloading robot sorts and unloads the scroll plate according to the results of previous inspections. The robot is driven by a servo motor and planetary reducer to move the rack and pinion gears in the X-axis direction, and the servo motor drives the electric cylinder to move up and down in the Z-axis direction. The pneumatic gripper adopts a parallel two-jaw design to avoid jamming the workpiece.

[0017] Furthermore, the unloading robot determines whether the vortex stationary disc is qualified based on the results of the height measurement mechanism and the vision inspection mechanism, and transports qualified products to the conveyor line, while unqualified products are sent to the NG belt line.

[0018] The workflow of this invention specifically includes the following steps: S1: The fixture is moved to the external area, and the operator places the scroll plate to be tested on the fixture in the correct direction; S2: The three-point vacuum detection mechanism on the fixture checks whether the scroll plate is flat and fits properly. After confirmation, the operator leaves the grating area and presses the start button with both hands; S3: The fixture moves to the first station, and the laser engraving machine engraves a unique code on the surface of the scroll plate; S4: The fixture moves to the second station, and the QR code reader scans the QR code and enters the information into the industrial control computer database; S5: The fixture moves to the third station, the height measuring cylinder extends, and six contact displacement sensors measure the height and flatness of the specified point. The results are uploaded to the industrial control computer database; S6: The fixture moves to the fourth station, and the industrial camera takes an image of the scroll plate to detect whether there are any missing holes and outputs the number of the missing part; S7: The fixture moves to the fifth station, and the unloading robot classifies and unloads the scroll plate according to the previous detection results.

[0019] The beneficial effects of this invention are as follows: By replacing traditional manual measurement with an automated inspection mechanism, the number of inspection steps is significantly reduced and repeatability is improved. Specifically, the vision inspection mechanism employs a high-resolution industrial camera and a dual-light source illumination system, effectively reducing the risk of false positives and false negatives due to fatigue. Furthermore, the equipment integrates an industrial control computer for data acquisition and storage, and laser engraving assigns a unique identification tag to each product, facilitating full traceability and quality control. In addition, the equipment is equipped with safety light curtains and an emergency stop button to ensure operator safety. In summary, this invention, through highly integrated automation technology, significantly improves the efficiency and accuracy of vortex disc inspection, while simultaneously achieving data management and full traceability, demonstrating significant industrial application value.

[0022] This invention provides an automated inspection and marking machine for vortex stationary disks. Its core lies in its highly integrated mechanical structure and information management system, which enables automatic inspection of the height, flatness, and hole leakage of the vortex stationary disk's machined surface. Combined with laser marking and QR code reading functions, it assigns a unique identification label to each product, facilitating full traceability and quality control. The following is in conjunction with the appendix... Figure 1 To be continued Figure 6 The specific embodiments of the present invention will be described in detail below.

[0023] The equipment is primarily structured around a frame 29, which is welded from square tubing and supports all functional modules while ensuring overall rigidity. Electrical components 30 are mounted on the bottom front of the frame 29, with a drawer-type mouse and keyboard unit above for operating the industrial control computer system. An integrated electrical box 41 is located on the left side of the frame 29, seamlessly integrated with the overall equipment design for enhanced flexibility. A two-hand start button 31, an emergency stop button 38, and a safety light curtain 37 are positioned at the front of the frame 29 to ensure operator safety. An aluminum profile protective cover covers the top of the equipment, enhancing safety and reducing interference from the external environment on testing accuracy. A rotatable touchscreen 33 is mounted on the right side of the frame 29. A vacuum air inspection mechanism 32, a vision display 34, an industrial control computer display 35, and a laser engraving machine touchscreen 36 are located inside the front of the equipment, allowing operators to easily monitor parameter changes.

[0024] S1: The fixture is moved to the external area, and the operator manually places the scroll plate to be tested onto the fixture 18 in the correct orientation. The fixture 18 has three air detection holes connected to the vacuum testing mechanism 32 to check whether the scroll plate is placed flat and properly aligned. Furthermore, the fixture 18 is equipped with a positioning key 19 and a foolproof screw 20. The positioning key 19 restricts the placement direction of the scroll plate, and the foolproof screw 20 prevents incorrect placement. The vacuum testing mechanism 32 detects whether the scroll plate is correctly placed by measuring changes in vacuum pressure and displays the results in real time on the industrial control computer display 35. After confirming that the scroll plate is correctly placed, the operator leaves the protected area of ​​the safety light curtain 37 and presses the two-hand start button 31 to start the equipment.

[0025] S2: Tooling 18 is driven by the loading module robot 14, moving along the linear guide 17 to the first station. The loading module robot 14 is powered by a servo motor 15 driving a lead screw 16, and the high-precision linear guide 17 ensures the smooth movement of tooling 18 in the plane. A laser engraving machine 39 is installed at the first station. The laser engraving machine 39 consists of a three-axis slide, which adjusts the engraving position along the X, Y, and Z axes respectively. The laser engraving machine 39 engraves a unique code on the surface of the scroll plate, including both plain text and QR codes. The laser engraving machine 39 controls the engraving parameters through an industrial control computer to ensure that the code on each scroll plate is unique and traceable. After engraving is completed, tooling 18 continues to move along the linear guide 17 to the second station.

[0026] S3: The second station is equipped with a QR code reading mechanism 1, which includes a QR code reader 4, a light-shielding cylinder 2, and a light-shielding plate 3. The light-shielding cylinder 2 controls the extension and retraction of the light-shielding plate 3, protecting the lens of the QR code reader 4 from laser reflection when not in operation. When the fixture 18 moves to the second station, the light-shielding cylinder 2 retracts, so that the light-shielding plate 3 no longer blocks the lens of the QR code reader 4. After scanning the QR code on the surface of the scroll plate, the QR code reader 4 uploads the basic data to the industrial control computer database and displays it in real time on the industrial control computer display 35. After scanning, the light-shielding cylinder 2 extends, so that the light-shielding plate 3 continues to cover and protect the photosensitive components inside the lens of the QR code reader 4. After scanning is completed, the fixture 18 continues to move along the linear guide rail 17 to the third station.

[0027] S4: The third station is equipped with a height measuring mechanism 5. The height measuring mechanism 5, driven by a height measuring cylinder 6, uses six contact displacement sensors to measure height and flatness. The six contact displacement sensors are contact displacement sensor A8, contact displacement sensor B9, contact displacement sensor C10, contact displacement sensor D11, contact displacement sensor E12, and contact displacement sensor F13. A height limiting block 7 is located at the end of the height measuring cylinder 6 to ensure that the sensors reach a fixed position during each measurement, thus guaranteeing repeatability. When the fixture 18 moves to the third station, the height measuring cylinder 6 extends, and the six contact displacement sensors correspond to the six measuring points of the scroll plate, outputting data and the height difference and flatness between the two points to the industrial control computer, which displays the data in real time on the industrial control computer's monitor 35. After the height measurement is completed, the fixture 18 continues to move along the linear guide rail 17 to the fourth station.

[0028] S5: The fourth station is equipped with a vision inspection mechanism, which uses a high-resolution industrial camera in conjunction with a dual-light source supplementary lighting system. The industrial camera uses a preset template to detect whether there are any missed holes in the vortex stationary disk and outputs the number of the missed area. The light source system of the vision inspection mechanism reduces the missed detection rate by adjusting the brightness and angle. The inspection results are uploaded to the industrial control computer database and displayed in real time on the vision display 34. The image of the industrial camera itself is also displayed in real time on the vision display 34, making it easy for the operator to observe the inspection process. After completing the vision inspection, the fixture 18 continues to move along the linear guide 17 to the fifth station.

[0029] S6: The fifth station is equipped with a loading robot 22, which sorts and loads the scroll plates according to the previous inspection results. The loading robot 22 is driven by a servo motor 23 and a planetary reducer 24 to move the rack and pinion gear 25 in the X-axis direction, and a servo motor 26 drives an electric cylinder 27 for Z-axis lifting. The pneumatic gripper 28 adopts a parallel two-jaw design to avoid jamming the workpiece. When the fixture 18 moves to the fifth station, the loading robot 22 determines whether the scroll plates are qualified according to the results of the height measuring mechanism 5 and the vision inspection mechanism, and transports qualified products to the conveyor line, while unqualified products are sent to the NG belt line 40.

[0030] Throughout the entire workflow of the equipment, the various functional modules work closely together to ensure the efficient completion of the detection, engraving, data acquisition, and sorting of the vortex stationary disks. The laser engraving machine 39 assigns a unique identification tag to each vortex stationary disk. The QR code reader 4 reads the code and enters the information into the industrial control computer database. The height measurement mechanism 5 and the vision inspection mechanism respectively complete the height and flatness detection, as well as the hole leakage detection. Finally, the unloading robot 22 sorts and unloads the disks based on the inspection results. The equipment is equipped with a safety light curtain 37 and an emergency stop button 38 to ensure the safety of the operators. Meanwhile, the vacuum inspection mechanism 32 and the high-precision linear guide rail 17 further enhance the reliability and detection accuracy of the equipment.

[0031] This invention, through the specific embodiments described above, achieves fully automated detection and classification of scroll plates, significantly reducing detection steps and improving repeatability. The vision inspection mechanism employs a high-resolution industrial camera and a dual-light source illumination system to effectively reduce the risk of false positives and false negatives due to fatigue. The equipment integrates an industrial control computer for data acquisition and storage, and laser engraving assigns a unique identification tag to each product, facilitating full traceability and quality control. Furthermore, the equipment is equipped with a safety light curtain 37 and an emergency stop button 38 to ensure operator safety. In summary, this invention significantly improves the efficiency and accuracy of scroll plate detection through highly integrated automation technology, while simultaneously achieving data management and full traceability, demonstrating significant industrial application value.
