Description

Technical Field

[0001] This invention belongs to the field of coating testing technology, specifically relating to a testing system and method for testing the adhesion of steel coating surfaces. Background Technology

[0002] The traditional pull-out method measures adhesion by directly bonding a pull head to the coating surface, then pulling it after curing until the coating and substrate are completely detached. The pull-out force is recorded as the adhesion between the coating and substrate. While this method allows for quick adjustment of the assembly position using a centering mold, it still cannot quickly select the measurement center based on the sample specifications. This leads to assembly errors in actual operation. Furthermore, during the pull-out process, the bonded end of the pull head may deviate from the sample center, causing the pull-out force to be non-perpendicular and generating bending moments, thus reducing the accuracy of the adhesion reading. Therefore, we propose a detection system and method for the adhesion of steel coating surfaces. Summary of the Invention

[0003] This invention provides a detection system and method for detecting the adhesion of steel coating surfaces, in order to solve the problems mentioned in the background art.

[0004] This invention provides the following technical solution: a detection system for the adhesion of steel coating surfaces, comprising a detection carrier, an inner working slot for the detection carrier, and a path correction analysis module mounted on the outer side of the detection carrier. The detection carrier is equipped with a tensile component, a reading module, a sample positioning fixture, and a correction parameter calibration module. Both the reading module and the correction parameter calibration module are signal-connected to the path correction analysis module. After the sample to be tested is loaded inside the sample positioning fixture, the tensile component fixes the sample and pulls it out. The reading module outputs the detection data generated after the tensile component pulls out. The correction parameter calibration module is used to calibrate the sample interval range according to the measurement point type before the sample positioning fixture pulls out. The path correction analysis module is used to read the measurement signal acquired by the correction parameter calibration module and further correct the test position of the tensile component, ensuring that the tensile component is vertically fixed at the center of the sample.

[0005] A further improvement of the present invention is that the pulling component includes a path limiting seat, a pulling pneumatic actuator, and a pulling head. The path limiting seat is installed on the top of the detection carrier, and the output end of the pulling pneumatic actuator is fixedly connected to the pulling head.

[0006] A further improvement of the present invention is that the reading module includes a force gauge and a signal line terminal, the signal line terminal is installed inside the detection carrier, and the signal line terminal is connected to the pulling head via the force gauge.

[0007] A further improvement of the present invention is that the correction parameter calibration module includes a vertical plane calibration detection module, a center point calibration detection module, and a horizontal side calibration detection module. The vertical plane calibration detection module comprises at least two sets, symmetrically distributed and fixedly connected to the inner wall of the testing vehicle. The vertical plane calibration detection module is used to measure the spatial distance between the sample and the side wall of the testing vehicle after the sample to be tested is fixed by the sample positioning fixture. The center point calibration detection module is arranged in a four-corner matrix, with the adhesive end of the pull-out head located at the center of the four center point calibration detection modules. When adjusting the pull-out form of the pull-out head, the center point calibration detection module calibrates the centered position of its adhesive end. The horizontal side calibration detection module is located inside the testing vehicle, comprising four modules, with each pair forming a group. The two groups of horizontal side calibration detection modules are symmetrically distributed. The horizontal side calibration detection modules are arranged on the bottom surface of the testing vehicle. The horizontal side calibration detection modules, in a parallel state, perform a secondary measurement of the spatial distance between the sample and the side wall of the testing vehicle.

[0008] A further improvement of the present invention is that the vertical plane calibration detection module includes an electromagnetic push rod and an infrared rangefinder, the electromagnetic push rod is horizontally arranged, and the infrared rangefinder is fixedly connected to the output end of the electromagnetic push rod.

[0009] A further improvement of the present invention is that the center point calibration and detection module comprises a radiation output unit and a cover mirror mounted on the emission surface of the radiation output unit.

[0010] A further improvement of the present invention is that the path correction analysis module includes a measurement mode parameter adjustment unit and a selected data storage unit. The measurement mode parameter adjustment unit is signal-connected to the selected data storage unit. The measurement mode parameter adjustment unit is used to read corresponding parameters from the selected data storage unit according to the pulling form after the pulling head is adjusted. The selected data storage unit obtains the detection mark point corresponding to the current pulling form and marks it through the center point calibration detection module.

[0011] A further improvement of the present invention is that the path correction analysis module further includes an axial measurement signal transmission unit and a deviation error measurement unit. The axial measurement signal transmission unit is signal-connected to the deviation error measurement unit. The axial measurement signal transmission unit is used to read the spatial distance parameters between the sample and the side wall of the detection vehicle detected by the vertical plane calibration detection module and the horizontal side calibration detection module and send them to the deviation error measurement unit. The deviation error measurement unit calculates the difference in the distance between the two sides of the sample after it has been fixed by the sample positioning fixture.

[0012] A further improvement of the present invention is that the selected data storage unit and the deviation error measurement unit are signal-connected to a selected data analysis and correction unit, and the selected data analysis and correction unit is signal-connected to a secondary debugging parameter display unit. The selected data analysis and correction unit is used to output the position correction parameters after the current sample is fixed according to the difference parameters calculated by the deviation error measurement unit, and finally displayed by the secondary debugging parameter display unit.

[0013] A further improvement of the present invention is a detection method for a steel coating surface adhesion detection system, comprising the following steps: Step S1: Place the sample to be tested inside the working slot of the testing carrier, adjust the sample positioning fixture to clamp the sample to be tested, and manually adjust the sample to reach the center position. Step S2: Adjust the pulling form, select the type of mold for the bonding end of the pulling head, and the center point calibration detection module projects the center mark point according to the type of mold for the bonding end to calibrate the position of the sample to be tested and the bonding end. After the sample to be tested is fixed by the sample positioning fixture, the vertical plane calibration detection module and the center point calibration detection module simultaneously measure the spatial distance between the sample and the side wall of the detection carrier. Step S3: The axial measurement signal transmission unit reads the spatial distance parameters between the sample and the side wall of the detection vehicle detected by the vertical plane calibration detection module and the horizontal side calibration detection module and sends them to the deviation error measurement unit. The deviation error measurement unit calculates the difference in the distance between the two sides of the sample after it is fixed by the sample positioning fixture. The selected data analysis and correction unit outputs the position correction parameters of the current sample after it is fixed according to the difference parameters calculated by the deviation error measurement unit. Finally, the secondary debugging parameter display unit displays the parameters, and the operator debugs according to the displayed information.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: By measuring the mode parameter adjustment unit and selecting the data storage unit, the system can read the corresponding detection mark points according to the adjusted pulling form, and use the center point calibration detection module to make indication marks, so that the equipment can quickly complete the adaptation and debugging when changing different specifications of pulling heads or changing the test standards, keeping the pulling head itself in the center at all times. Then, through the cooperation of the path correction analysis module and the correction parameter calibration module, the tension component is vertically fixed to the center of the test sample. The vertical plane calibration detection module, the horizontal side calibration detection module and the deviation error measurement unit calculate the difference in the interval between the two sides of the sample after it is fixed by the sample positioning fixture. The correction parameters are displayed through the secondary debugging parameter display unit, which allows for quick manual adjustment, avoiding bending moment interference caused by tension offset or tilt, and ensuring the stability of subsequent pulling test data.

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted. All other specific embodiments obtained by those skilled in the art based on the specific embodiments of the present invention without creative effort are within the scope of protection of the present invention. Please see Figures 1-3 A detection system for the adhesion of steel coating surfaces includes a detection carrier 1, an inner working slot 11, and a path correction analysis module 2 mounted on the outer side of the detection carrier 1. The detection carrier 1 is equipped with a tension component 3, a reading module 4, a sample positioning fixture 5, and a correction parameter calibration module 6. Both the reading module 4 and the correction parameter calibration module 6 are signal-connected to the path correction analysis module 2. After the sample to be tested is loaded inside the sample positioning fixture 5, the sample to be tested is fixed by the tension component 3 and pulled. The reading module 4 outputs the detection data generated after the tension component 3 pulls out. The correction parameter calibration module 6 is used to calibrate the sample interval range according to the measurement point type before the pull-out test of the sample positioning fixture 5. The path correction analysis module 2 is used to read the measurement signal acquired by the correction parameter calibration module 6 and correct the test position of the tension component 3, ensuring that the tension component 3 is vertically fixed at the center of the sample.

[0020] In this embodiment, the pulling assembly 3 includes a path limiting seat 31, a pulling pneumatic actuator 32, and a pulling head 33. The path limiting seat 31 is installed on the top of the detection carrier 1, and the output end of the pulling pneumatic actuator 32 is fixedly connected to the pulling head 33. In actual pulling operations, the pulling pneumatic actuator 32 provides driving force to the pulling head 33, so that the pulling head 33 completes the pulling action vertically along the path defined by the path limiting seat 31.

[0021] In this embodiment, the reading module 4 includes a force gauge 41 and a signal line terminal 42. The signal line terminal 42 is installed inside the detection carrier 1 and is connected to the pulling head 33 via the force gauge 41. The force gauge 41 is used to measure the pulling force data after the pulling pneumatic actuator 32 and the pulling head 33 complete the pulling action, and the data is fed back by the secondary debugging parameter display unit 26 in the path correction analysis module 2.

[0022] In this embodiment, the correction parameter calibration module 6 includes a vertical plane calibration detection module 61, a center point calibration detection module 62, and a horizontal side calibration detection module 63. The vertical plane calibration detection module 61 consists of at least two sets, symmetrically distributed and fixedly connected to the inner wall of the detection carrier 1. The vertical plane calibration detection module 61 is used to measure the spatial distance between the sample and the side wall of the detection carrier 1 after the sample to be tested is fixed by the sample positioning clamp 5. The center point calibration detection module 62 is arranged in a four-corner matrix, with the adhesive ends of the pull-out head 33 located at four corners. The center point calibration detection module 62 is used to calibrate the center position of the adhesive end when the pull-out head 33 is adjusting the pull-out form. The horizontal side calibration detection module 63 is set inside the detection carrier 1. There are four horizontal side calibration detection modules 63, and they are divided into two groups. The two groups of horizontal side calibration detection modules 63 are symmetrically distributed. The horizontal side calibration detection modules 63 are arranged on the bottom surface of the detection carrier 1. The horizontal side calibration detection modules 63 are in a parallel state, and the space between the secondary measurement sample and the side wall of the detection carrier 1 is separated.

[0023] In this embodiment, the vertical plane calibration and detection module 61 includes an electromagnetic push rod and an infrared rangefinder. The electromagnetic push rod is horizontally positioned, and the infrared rangefinder is fixedly connected to the output end of the electromagnetic push rod. When the vertical plane calibration and detection module 61 performs a vertical plane test, the electromagnetic push rod moves the infrared rangefinder along its stroke. The infrared rangefinder measures whether the measured distance of the current vertically illuminated surface shifts after the horizontal stroke. If a shift occurs, the sample to be tested is tilted and not centered. If the measured distance remains constant, the plane of the sample to be tested is vertical. Within the detection range of the surface calibration detection module 61, the measured distance of the current vertical irradiation surface after horizontal travel does not deviate. Subsequently, a secondary verification is performed by the horizontal side calibration detection module 63. The emitting end of the horizontal side calibration detection module 63 is set horizontally. The distance between the horizontal side calibration detection module 63 and the side wall of the sample to be tested is measured by the horizontally emitted ranging rays of the two sets of horizontal side calibration detection modules 63. Since the two sets of horizontal side calibration detection modules 63 are at different measurement points, the pull-out position of the sample to be tested meets the requirements only when the measured distances of the two sets of horizontal side calibration detection modules 63 are the same.

[0024] In this embodiment, the center point calibration and detection module 62 includes a X-ray output unit and a cover mirror installed on the X-ray output unit's ejection surface. When the drawing mode of the drawing head 33 changes and the mold type needs to be changed, the cover mirror installed on the X-ray output unit's ejection surface is replaced according to the mold requirements so that the marking line ejected after covering meets the current mold requirements. The cover mirror can be pre-manufactured according to the mold's drawing range.

[0025] In this embodiment, the path correction analysis module 2 includes a measurement mode parameter adjustment unit 21 and a selected data storage unit 22. The measurement mode parameter adjustment unit 21 is signal-connected to the selected data storage unit 22. The measurement mode parameter adjustment unit 21 is used to read the corresponding parameters into the selected data storage unit 22 according to the pulling form after the pulling head 33 is adjusted. The selected data storage unit 22 obtains the detection mark point corresponding to the current pulling form and marks it through the center point calibration detection module 62.

[0026] In this embodiment, the path correction analysis module 2 further includes an axial measurement signal transmission unit 23 and a deviation error measurement unit 24. The axial measurement signal transmission unit 23 is signal-connected to the deviation error measurement unit 24. The axial measurement signal transmission unit 23 is used to read the spatial distance parameters between the sample and the side wall of the detection carrier 1 detected by the vertical plane calibration detection module 61 and the horizontal side calibration detection module 63 and send them to the deviation error measurement unit 24. The deviation error measurement unit 24 calculates the difference in the distance between the two sides of the sample after it is fixed by the sample positioning clamp 5.

[0027] In this embodiment, the selected data storage unit 22 and the deviation error measurement unit 24 are signal-connected to the selected data analysis and correction unit 25, and the selected data analysis and correction unit 25 is signal-connected to the secondary debugging parameter display unit 26. The selected data analysis and correction unit 25 is used to output the position correction parameters after the current sample is fixed according to the difference parameters calculated by the deviation error measurement unit 24, and finally displayed by the secondary debugging parameter display unit 26.

[0028] The detection method of the present invention includes the following steps: Step S1: Place the sample to be tested inside the working slot 11 set in the testing carrier 1, adjust the sample positioning fixture 5 to clamp the sample to be tested, and manually adjust the sample to reach the center position. Step S2: Adjust the pulling form, select the bonding end mold type of the pulling head 33, and the center point calibration detection module 62 projects the center mark point according to the bonding end mold type to calibrate the position of the sample to be tested and the bonding end. After the sample to be tested is fixed by the sample positioning fixture 5, the vertical plane calibration detection module 61 and the center point calibration detection module 62 simultaneously measure the spatial distance between the sample and the side wall of the detection carrier 1. Step S3: The axial measurement signal transmission unit 23 reads the spatial distance parameters between the sample and the side wall of the detection carrier 1 detected by the vertical plane calibration detection module 61 and the horizontal side calibration detection module 63 and sends them to the deviation error measurement unit 24. The deviation error measurement unit 24 calculates the difference in the distance between the two sides of the sample after it is fixed by the sample positioning clamp 5. The selected data analysis correction unit 25 outputs the position correction parameters after the sample is fixed according to the difference parameters calculated by the deviation error measurement unit 24. Finally, the secondary debugging parameter display unit 26 displays the parameters, and the operator makes adjustments according to the displayed information.
