Description

Technical Field

[0001] This invention belongs to the field of metal smelting technology, specifically relating to a fully automated online processing detection device and method for end-hardenability testing. Background Technology

[0002] End-hardenability is a key performance indicator for measuring the uniformity of hardness distribution in metallic materials after heat treatment. It directly affects the service life, load-bearing capacity, and safety and reliability of mechanical parts, and has irreplaceable testing significance in high-end equipment manufacturing fields such as automobile manufacturing, construction machinery, and aerospace. With the transformation of modern industry towards intelligence and efficiency, increasingly higher demands are being placed on the testing efficiency, accuracy, and automation level of end-hardenability of metallic materials. Online testing technology, due to its ability to provide real-time feedback on production quality and reduce production process interruptions, has become a core development direction in the field of industrial testing.

[0003] Currently, online testing devices and methods for the hardness of metallic materials have been applied to some extent in industrial production. However, many technical bottlenecks still exist in end-hardening testing scenarios, making it difficult to meet actual production needs. First, existing online hardness testing devices are generally only suitable for Brinell hardness testing. Their testing principles, force application methods, and testing head structures are not compatible with the Rockwell hardness testing standards required for end-hardening testing. This results in end-hardening testing still relying on offline testing equipment, leading to long testing cycles and the inability to achieve real-time quality monitoring during the production process, severely restricting the improvement of production efficiency.

[0004] Secondly, in the existing testing process, the standard block verification step relies entirely on manual handling. Operators need to manually complete a series of operations such as standard block installation, calibration, disassembly, and status confirmation. This is not only labor-intensive and consumes a lot of human resources, but also prone to unstable standard block verification accuracy due to the subjectivity and fatigue of manual operation, which in turn affects the reliability of subsequent hardness test results.

[0005] Furthermore, end-hardenability testing requires high precision in sample processing. The axes of the two ground planes (A and B) must be approximately equidistant from the product surface to ensure uniform stress and accurate testing points. However, in daily mass production, this positioning requirement is difficult to consistently achieve due to factors such as the precision of processing equipment, tooling and fixture positioning errors, and operator skill levels. This often results in substandard sample processing precision, increasing rework rates and production costs. Moreover, sample positioning deviations directly affect the accuracy of hardness test data, failing to accurately reflect the material's end-hardenability properties.

[0006] Furthermore, in the existing testing process, test data needs to be manually transcribed into a Laboratory Information Management System (LIMS) for storage, analysis, and traceability. This manual transcription process is not only inefficient and unable to meet the data processing needs of high-speed production lines, but it is also highly susceptible to human error, leading to data entry errors and data loss. This results in mismatches between the test data and the actual sample information, affecting the traceability and validity of the test data and causing significant difficulties for subsequent quality analysis and problem investigation.

[0007] Chinese Patent Application No. 202310534045.6 discloses a fully automatic online hardness testing device, relating to the field of hardness testing technology. The device includes: a bracket with a worktable mounted on it; a machine head moving platform slidably mounted on the bracket; a moving machine head slidably mounted on the machine head moving platform; a lifting motor assembly fixedly mounted on the machine head moving platform for driving the moving machine head to move vertically; an indentation generating device including a pressure plate and a loading mechanism, the loading mechanism being fixedly mounted on the moving machine head; and an indentation detection device for detecting indentations on a workpiece and generating Brinell hardness values.

[0063] Controlling the detection platform, the processing module, and the testing machine 5 to automatically perform specimen processing and hardness testing;

[0064] Judging the detection results and returning the data to the LIMS system.

[0065] Specifically, the fully automatic online processing and detection device for end hardenability provided by the embodiment of the present invention mainly includes a robotic arm assembly 1, a detection platform, a visual recognition component, a processing module, a testing machine 5, and a control system connected to the LIMS system.

[0066] Preferably, in the embodiment of the present invention, the detection platform is installed on the testing machine 5, the testing machine 5 is a hardness tester, and the detection platform is located below the camera 4. The detection platform includes a specimen stage installed on a driving mechanism that can move along the X, Y, and Z axes, and the running accuracy of the specimen stage ≤ 0.003 mm. The specimen stage is connected to the driving mechanism, and the driving mechanism controls the specimen stage to move. The specimen stage is used to place specimens. Before and after specimen detection, by moving the specimen stage, the specimen will return to the initial point position.

[0067] Preferably, in the embodiment of the present invention, the specimen stage is provided with a "卅"-shaped fixing seat with a spacing of 25 mm for placing multiple specimens.

[0068] Preferably, in the embodiment of the present invention, a displacement sensor is provided on the detection platform, which is used to detect the running position of the detection platform and correct the displacement error in real time to achieve precise control, and the running accuracy ≤ 0.003 mm.

[0069] As a preferred embodiment of the invention, the control system is provided with a size determination unit, which is used to determine whether the length and diameter of the sample meet the preset standard based on the visual recognition result.

[0070] Preferably, in this embodiment of the invention, the control system is provided with an interface module for communicating with the LIMS system, which is used to automatically receive detection schemes and upload detection data.

[0071] Preferably, in the embodiments of the present invention, such as Figure 1 As shown, the visual recognition component includes a camera 4, which is fixed at a certain angle on the testing machine 5. The camera 4 observes the position of the target block that needs to be verified. A region is fixed in the software to mark the initial hardness point landing position.

[0072] Preferably, in the embodiments of the present invention, such as Figure 1 and Figure 7 As shown, the processing module is located in processing area 3. The processing module includes a milling unit 11 for positioning the sample axis and milling the sample, and is equipped with an automatic flipping mechanism for rotating the sample 180°. In the sample processing step, after the sample is positioned according to the axis, a first surface (surface A in the figure) and a second surface (surface B in the figure) are distinguished. The milling unit 11 mills the first surface (surface A in the figure), and then the sample is flipped 180°. The milling unit 11 then mills the second surface (surface B in the figure). The first and second surfaces of the sample are two opposite surfaces on the sample, and the first and second surfaces are parallel.

[0073] Preferably, in the embodiments of the present invention, such as Figures 2 to 5 As shown, the testing platform is equipped with a standard block holder, which has adjustable movable slots 8 to accommodate standard blocks of different sizes. The standard block holder has at least two fixed slots 7, which are arranged opposite to the movable slots 8. The movable slots 8 cooperate with the fixed slots 7 to clamp the standard blocks. The standard block holder also includes a support plate 9, whose top surface is flat. Standard blocks can be placed on the top surface of the support plate 9. The fixed slots 7 are fixedly mounted on the support plate 9, and the movable slots 8 are mounted on the support plate 9. The position of the movable slots 8 on the support plate 9 is adjustable. By adjusting the position of the movable slots 8, the distance between the movable slots 8 and the fixed slots 7 can be adjusted, thus allowing for the matching of standard blocks of different diameters. The standard blocks are circular block structures.

[0074] In this embodiment of the invention, the movable bayonet 8 is installed on the support plate 9 by bolts. The support plate 9 is provided with a through hole for the bolt to pass through, and the movable bayonet 8 is provided with a waist-shaped hole for the bolt to pass through. The length of the waist-shaped hole is greater than the diameter of the bolt, so as to facilitate the adjustment of the position of the movable bayonet 8.

[0075] In embodiments of the present invention, such as Figures 2 to 5 As shown, two fixed bayonets 7 are provided, and the two fixed bayonets 7 are distributed in a V-shape. The two fixed bayonets 7 and one movable bayonet 8 are distributed in an isosceles triangle.

[0076] Preferably, in the embodiments of the present invention, such as Figures 2 to 5 As shown, the standard block holder is provided with support legs 10 that are inserted into the grooves on the sample stage. Multiple support legs 10 are provided. The support legs 10 are fixedly connected to the support plate 9. The support legs 10 are located on one side of the support plate 9, and the fixed latch 7 and the movable latch 8 are located on the other side of the support plate 9. Multiple support legs 10 are provided. The sample stage is provided with an equal number of grooves. Each support leg 10 is inserted into a groove, so that the standard block holder can be stably locked on the testing platform and is easy to disassemble and assemble.

[0077] The standard block holder is used for the standard block verification step. The verification process is as follows: the robotic arm places the standard block holder, which contains the standard blocks, onto the sample stage of the testing platform according to instructions. Each leg 10 of the standard block holder is inserted into a groove on the sample stage, and the support plate 9 is in a horizontal position. The camera 4 views the surface of the standard block holder from above. Through the image captured by the camera 4, the area of ​​the standard block to be verified is identified. Based on the visual positioning of the camera 4, the position of the standard block to be verified is aligned with the center of the indenter of the testing machine 5. Then, the indenter of the testing machine 5 moves downward to apply pressure to the sample block below for downward verification. Three points to be verified can be selected on the computer. During the verification process, the testing machine 5 operates according to the standard loading curve. The entire process is controlled by the testing machine 5, which also returns the hardness value. If the first verification point is passed, the standard block is moved to the next point, and the verification process is repeated. After the three verification points are completed, a statistical judgment is made, and a verification report is generated.

[0078] After the verification test is completed, the testing platform descends to the starting point according to the instructions, and the robotic arm then removes the standard sample holder from the testing platform.

[0079] The automated verification test uses standard test blocks with known standard hardness values ​​to verify the accuracy of the testing system, ensuring the reliability and comparability of subsequent sample test results, guaranteeing testing accuracy and consistency, replacing manual comparison, and eliminating human error. The automated verification system completes the entire process through the combination of a robotic arm, vision positioning, and the automatic loading mechanism of the testing machine, ensuring the standardization and objectivity of the verification process.

[0080] As a preferred embodiment of the present invention, the fully automatic online processing and testing device for end hardenability further includes a compensation structure, which includes multiple magnetically adsorbable compensation plates. When testing short-length samples, the length of the sample is supplemented by stacking the compensation plates.

[0081] In the sample loading step, the following method is adopted: Figure 6The feeding platform 2 shown has a sample placed on it. The feeding platform 2 is equipped with a sample port, and the sample is placed in the sample port. There are multiple sample ports, and the diameter of the sample port is 25mm. A detection sensor for feeding position is installed in the test area.

[0082] Secondly, such as Figures 1 to 8 As shown, this embodiment of the invention also provides a fully automated online machining detection method for end-hardening hardness based on the above-described structure, comprising the following steps:

[0083] S1. Reset Step: Control the robotic arm assembly 1 and the detection platform to return to the starting position;

[0084] S2, Standard Block Verification Steps: Determine the verification position of the standard block based on the visual recognition results, and control the detection platform to perform hardness verification;

[0085] S3. Sample loading and testing steps: The robotic arm assembly 1 sends the sample into the positioning platform and tests its dimensions based on the information transmitted from the LIMS system.

[0086] S4. Sample processing steps: For samples that meet the size requirements, after positioning them according to the axis, mill the two opposite surfaces.

[0087] S5. End-of-end hardenability test steps: The robotic arm assembly 1 places the milled sample on the test platform and controls the testing machine 5 to perform Rockwell hardness test according to the test plan generated by the LIMS system.

[0088] S6. Result Judgment and Data Feedback Steps: Automatically sort samples according to test results and upload test data to the LIMS system.

[0089] In step S2 above, the robotic arm assembly 1 places the standard block holder containing the standard blocks onto the testing platform according to instructions. Based on the visual positioning of the camera 4, the position of the standard block to be verified is determined, and then a downward verification is performed. Three points to be verified can be selected on the computer. After the verification test is completed, the testing platform descends to the starting point according to instructions, and the robotic arm then removes the standard block sample holder from the testing platform.

[0090] In step S3 above, the sample loading process is as follows: the sample is placed on the loading platform 2, and the robotic arm assembly 1 sends the sample to the positioning platform located in the processing area 3 according to the sample information received from the LIMS system. After the sample is positioned on the positioning platform, it is determined whether the size of the sample meets the standard requirements. If the size of the sample meets the standard requirements, the sample is sent to the processing module in the processing area for milling. Otherwise, the sample is sent to the sample removal area.

[0091] The robotic arm places the sample onto the positioning platform, and the sensor detects the sample's arrival signal, initiating visual inspection. In processing area 3, the visual recognition component also includes a size detection module. This module comprises an industrial camera, which, as the core, acquires a complete outline image of the sample. After image preprocessing, it extracts the boundary and outer diameter contours of both ends of the sample to measure its length and diameter. The measured dimensions are then compared with the standard size data (specified in GB / T 225-2006) to automatically determine whether the sample meets the inspection standard.

[0092] In step S4 above, after the sample is positioned according to the axis, the first surface and the second surface are distinguished. After the milling unit 11 mills the first surface of the sample, the sample is rotated 180° and the milling unit 11 mills the second surface of the sample. After the iron filings are blown off, the sample is transferred to the testing machine 5.

[0093] In step S5 above, the robotic arm assembly 1 places the milled sample on the testing platform. The robotic arm gripper pushes the sample to ensure that the sample is in contact with the zero point of the test. Then the testing platform rises, and the testing machine 5 is controlled to perform Rockwell hardness testing according to the testing plan generated by the LIMS system. After the test is completed, it is determined whether the sample is qualified. Qualified products are unloaded into the qualified product area, and unqualified products are unloaded into the unqualified product area. The test data is directly returned to the LIMS system.

[0094] In step S6 above, the testing machine 5 automatically generates a test plan based on the sample test requirements received from the LIMS system and conducts the test. After the test is completed, the data is directly returned to the LIMS system.

[0095] In step S3 above, the fully automated online machining detection method for end hardenability according to this embodiment of the invention further includes:

[0096] Short-length specimen compensation procedure: For specimens shorter than the standard value, a compensation piece is added to its end to compensate for the specimen length to the specified standard. This enables the use of magnetic strip superposition compensation technology in the case of short-length specimens, achieving effective utilization of short-length specimens.

[0097] For specimens shorter than the standard value, a compensating plate is installed at the other end of the specimen during the end-quench test. The compensating plate is a magnetic sheet that can be attracted to the specimen. The thickness of the compensating plate is 1 mm. Multiple compensating plates can be installed and stacked. Adjacent compensating plates can attract each other to ensure that the total length of the specimen (the length of the specimen body plus the thickness of the compensating plate) meets the test requirements. After compensation, the specimen can be placed back on the loading platform. Once the specimen length meets the standard requirements and the robotic arm gripper can place the specimen on the testing platform, the specimen can be pushed to the zero-point position of the test to achieve equivalent testing conditions.

[0098] The above-mentioned fully automated online processing and testing device and method for end-hardenability has the following technical advantages:

[0099] 1. This solves the problem that current end-hardening Rockwell hardening equipment cannot verify standard blocks.

[0100] 2. This solves the problem that current equipment of this type does not have automatic loading and unloading.

[0101] 3. This solves the current problem of not being able to automatically determine whether a sample meets the testing standard requirements.

[0102] 4. This solves the problem that current equipment of this type cannot automatically process the A and B sides of the sample.

[0103] 5. This solves the problem that current equipment of this type does not automatically receive test information and generate test plans.

[0104] 6. The problem of samples being too short to be tested has been solved.

[0105] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
