Description

Technical Field

[0001] This invention relates to the field of automated measurement technology, and in particular to an automatic adhesion strength measurement system and method. Background Technology

[0002] The adhesion strength of aluminum trichloride crystals is an important reference indicator for the surface properties of the inner wall material of the crystallization tank. Currently, the main methods for measuring the adhesion strength of crystals are the centrifugal rotation method and the direct push-pull method. These measurement methods are all manual operations on a single experimental surface. First, crystallization is performed on a single surface of the experimental plate to be tested, and then the adhesion force between the crystal and the experimental plate is measured by a force gauge. Due to the different angles and speeds of force application, the test results are greatly affected by the human factors of the operator, and the measurement results have errors. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the problem that the adhesion strength measurement in the prior art is carried out by manual operation on a single experimental surface, which is greatly affected by the human factors of the operator and the measurement results are erroneous, an automatic adhesion strength measurement system and measurement method are provided.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: an automatic adhesion strength measurement system, comprising:

[0005] Crystallization module, used to deposit aluminum trichloride crystals onto an experimental plate;

[0006] The rotating module includes a rotating table, which is rotatably mounted with a plurality of clamping stations for holding experimental plates along its circumference. The rotating module also includes a pushing component for rotating the clamping stations and a locking component for locking the clamping stations after rotation. The clamping stations can not only rotate with the rotating table but also rotate on their own axis.

[0007] An automatic feeding module is used to transport experimental plates with adhered crystals to the rotating module;

[0008] The visual measurement module is used to measure the area of ​​crystals on the experimental plate;

[0009] An automatic measurement module is used to remove crystals from the experimental plate and obtain the maximum tangential adhesion force generated during the crystal removal process.

[0010] First, the automatic feeding module transports the test board to the clamping station, where it is clamped. Each clamping station holds one test board. The vision measurement module measures the adhesion area of ​​crystals on the test surface of the test board. Then, the rotary table is rotated so that the test surface is directly opposite the automatic measurement module. The automatic measurement module removes the crystals from the test board and obtains the maximum tangential adhesion force generated during the crystal removal process to obtain the adhesion strength at that point. Then, the pushing component pushes the clamping station to rotate 90°, and the test board on it rotates 90° synchronously. The locking component locks the test board in this state. The vision measurement module measures the adhesion area of ​​crystals on the surface directly opposite the test board after rotation, and the automatic measurement module measures the maximum tangential adhesion force on that surface and calculates the adhesion strength of that surface. The clamping station continues to rotate until all test surfaces have been measured.

[0011] The above technical solution utilizes a rotating module to automatically measure the adhesion strength of multiple experimental plates and the crystallization of multiple surfaces of each experimental plate, thereby improving measurement efficiency and accuracy and reducing errors caused by human factors in the measurement results.

[0012] Furthermore, the pushing component includes an active mechanism and an auxiliary mechanism. The active mechanism includes a moving platform, with a moving block slidably mounted above the moving platform. A lever for rotating the clamping station is fixed on the moving block. The auxiliary mechanism includes a telescopic cylinder, with a second electromagnet fixed to the output end of the telescopic cylinder. Iron blocks that attract the second electromagnet are fixed to the four side walls of the clamping station. A rotating shaft is located at the bottom of the clamping station, and a deep groove ball bearing is embedded in the corresponding position of the rotating platform. The rotating shaft and the deep groove ball bearing cooperate to achieve the rotation of the clamping station. First, the moving platform drives the moving block to move towards the clamping station. The lever contacts the clamping station and drives the clamping station to rotate counterclockwise. When it rotates to a certain angle, the output end of the telescopic cylinder extends to a designated position, the second electromagnet is energized, and it attracts the iron blocks on the side walls of the clamping station, thereby achieving a 90° rotation of the clamping station.

[0013] Furthermore, each of the four corners of the clamping station is provided with a positioning hole. The locking assembly includes an upper connecting block and a lower connecting block located in the positioning hole. A connecting spring is provided between the upper connecting block and the lower connecting block. The rotary table is provided with four positioning slots corresponding to each clamping station. A first electromagnet is provided inside the positioning slot for engaging with the lower connecting block. When the first electromagnet is energized, the lower connecting block engages with the first electromagnet under the tension of the connecting spring, thereby fixing the clamping station. When the first electromagnet is de-energized, the lower connecting block disconnects from the first electromagnet and returns to its initial position under the tension of the connecting spring, thereby releasing the clamping station.

[0014] Furthermore, each clamping station has a recessed center forming a fixed base for placing the experimental board, and the fixed base has a front clamping block and a rear clamping block on both sides for clamping the experimental board. The clamping station is equipped with a slide rail, and a slider matching the slide rail is provided below the rear clamping block. The slider is slidably connected to the slide rail. A tension spring connects the front clamping block and the rear clamping block, and the center of the rotary table is equipped with a guide rod cylinder for pushing and pulling the rear clamping block. The extension and retraction of the output shaft of the guide rod cylinder drives the rear clamping block to move closer to or away from the front clamping block, thereby realizing the clamping and releasing of the experimental board.

[0015] Furthermore, the automatic measurement module includes an X-axis drive mechanism and an X-axis translation stage connected to the output end of the X-axis drive mechanism. A Y-axis drive mechanism is mounted on the X-axis translation stage, and the output end of the Y-axis drive mechanism is connected to the Y-axis translation stage. A Z-axis drive mechanism is mounted on the Y-axis translation stage, and the output end of the Z-axis drive mechanism is connected to the Z-axis translation stage. A scraper and a laser displacement sensor are fixed on the Z-axis translation stage, and a pressure sensor is provided at the bottom of the scraper. First, the laser displacement sensor measures the distance between the scraper and the experimental plate. Then, the X-axis drive mechanism, Y-axis drive mechanism, and Z-axis drive mechanism drive the scraper to move until it contacts the surface to be tested on the experimental plate. The Z-axis drive mechanism drives the scraper to remove crystals. The pressure sensor measures the maximum tangential adhesion force generated during the crystal removal process.

[0016] Furthermore, several piezoelectric ceramic sheets are fixed above the scraper. The two ends of the piezoelectric ceramic sheets are connected to the positive and negative terminals of the power supply. The natural frequency of the crystal is obtained through modal analysis using ANSYS Workbench. The crystal will induce resonance at its natural frequency and the amplitude will be the largest. A high-frequency signal with the same magnitude as the natural frequency of the crystal is emitted by an ultrasonic generator and applied to the piezoelectric ceramic sheets. The piezoelectric ceramic sheets will cause the crystal to vibrate at high frequency, thereby removing the residual crystal on the surface of the scraper after each measurement. This avoids experimental errors caused by residual crystal on the scraper surface and improves the accuracy of the measurement results.

[0017] Furthermore, the crystallization module includes a reactor and a collector. Experimental plates are regularly placed in the collector. Solid anhydrous aluminum trichloride crystals are added to the reactor and the reactor is heated to its sublimation temperature of 180°C. The solid anhydrous aluminum trichloride crystals will vaporize to generate aluminum trichloride gas, which enters the collector through the sublimation tube between the reactor and the collector. Due to the lower temperature inside the collector, the aluminum trichloride gas will condense on the experimental plates inside the collector to form aluminum trichloride crystals.

[0018] Furthermore, the automatic feeding module includes a horizontal transfer cylinder and a horizontal transfer frame connected to the output end of the horizontal transfer cylinder. A lifting cylinder is installed on the horizontal transfer frame, and a pneumatic gripper is installed at the output end of the lifting cylinder. Since crystals are corrosive, the surface of the pneumatic gripper is coated with a polytetrafluoroethylene (PTFE) coating. The PTFE coating has good heat resistance and corrosion resistance, thereby improving the service life of the pneumatic gripper. The pneumatic gripper picks up the experimental plate and, under the combined action of the horizontal transfer cylinder and the lifting cylinder, reaches the designated position of the fixed seat.

[0019] Furthermore, the crystallization module, automatic feeding module, rotation module, vision measurement module, and automatic measurement module are all located inside a sealed chamber. Since aluminum trichloride crystals react with moisture in the air when exposed to air to generate hydrogen chloride gas, all of the above modules are located inside a sealed chamber to ensure that air circulation with the outside is blocked during the measurement process. At the same time, a dehumidification device is also installed inside the chamber to absorb moisture from the air, reducing the impact of environmental factors on the measurement results. The sealed chamber is also equipped with an operating door for convenient operation of the modules within the measurement system by the experimental personnel.

[0020] A measurement method using the above-mentioned automatic adhesion strength measurement system includes the following steps:

[0021] S1. Place the experimental plate material regularly in the collector, add solid anhydrous aluminum trichloride crystals to the reactor, heat the crystals to 180°C to sublimate the crystals and generate aluminum trichloride gas, which then forms crystals on the experimental plate.

[0022] S2. Start the automatic feeding module, and control the pneumatic gripper to move to the top of the experimental board to clamp it and transfer it to the designated position of the clamping station through the horizontal movement cylinder and the lifting cylinder.

[0023] S3. The control system controls the output shaft of the guide rod cylinder to retract, causing the rear clamping block to move away from the front clamping block, releasing the pneumatic gripper and placing the experimental plate in the fixed seat. The output shaft of the guide rod cylinder extends, causing the rear clamping block to move closer to the front clamping block to clamp the experimental plate.

[0024] S4. As the rotary table rotates, the experimental board is placed sequentially on several clamping stations by the automatic feeding mechanism. The control system controls the first electromagnet on the rotary table to de-energize, causing it to disconnect from the lower connecting block in the positioning hole.

[0025] S5. The moving block pushes the lever forward to move it to make the clamping station rotate counterclockwise. The output shaft of the telescopic cylinder extends and the second electromagnet is energized and attracts the iron block.

[0026] S6. The output shaft of the telescopic cylinder returns to the initial position. At the same time, the second electromagnet is de-energized, and the control system controls the first electromagnet on the rotary table to be energized so that it attracts the lower connecting block in the positioning hole to fix the clamping position.

[0027] S7. The vision measurement module is positioned directly over the test surface of the experimental board and acquires the adhesion area of ​​crystals on the test surface. The obtained data is uploaded to the host computer Raspberry Pi in real time.

[0028] S8. The distance between the scraper and the experimental plate is measured by a laser displacement sensor, and the scraper is made to make accurate contact with the surface of the experimental plate by the X-axis drive mechanism, Y-axis drive mechanism and Z-axis drive mechanism. The maximum thrust of the scraper during the cleaning process is obtained by the pressure sensor and uploaded to the host computer to calculate the adhesion strength of aluminum trichloride crystals.

[0029] The beneficial effects of this invention are: this invention utilizes a rotating module to automatically measure the adhesion strength of multiple experimental plates and the crystallization of multiple surfaces of each experimental plate, thereby improving measurement efficiency and accuracy and reducing errors caused by human factors in the measurement results.

[0045] The invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner. Therefore, they only show the components relevant to the invention, and the orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be limiting, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0046] Example 1:

[0047] like Figure 1-5 As shown, this invention is an automatic adhesion strength measurement system, including a sealed chamber 100. Since aluminum trichloride crystals react with moisture in the air when exposed to air, generating hydrogen chloride gas, the measurement process must take place inside the sealed chamber 100 to prevent air circulation with the outside. Simultaneously, a dehumidification device 500 is installed inside the chamber 100 to absorb moisture from the air, reducing the influence of environmental factors on the measurement results. Furthermore, the chamber 100 is equipped with an operating door 110 for convenient operation of the modules within the measurement system by the experimental personnel. The chamber 100 also contains:

[0048] Crystallization module 400 is used to deposit aluminum trichloride crystals on an experimental plate;

[0049] The crystallization module 400 includes a reactor 410 and a collector 420. Experimental plates are regularly placed in the collector 420. Solid anhydrous aluminum trichloride crystals are added to the reactor 410 and the reactor 410 is heated to the sublimation temperature of 180°C. The solid anhydrous aluminum trichloride crystals will vaporize to generate aluminum trichloride gas, which enters the collector 420 through the sublimation tube between the reactor 410 and the collector 420. Since the temperature inside the collector 420 is low, the aluminum trichloride gas will condense on the experimental plates inside the collector 420 to form aluminum trichloride crystals.

[0050] The rotation module 200 includes a rotary table 210, on which a plurality of clamping stations 220 for holding experimental plates are rotatably mounted along its circumference. Each clamping station 220 has a rotating shaft at its bottom, and a deep groove ball bearing is embedded in a corresponding position on the rotary table 210. The rotating shaft and the deep groove ball bearing cooperate to achieve the rotation of the clamping station 220. The rotation module 200 also includes a pushing component for rotating the clamping stations 220 and a locking component for locking the clamping stations 220 after rotation. The clamping stations 220 can not only rotate with the rotary table 210 but also rotate on their own axis.

[0051] Each clamping station 220 has a recessed center portion with a fixed base 235 for placing the experimental board. The fixed base 235 has a front clamping block 223 and a rear clamping block 224 on either side for clamping the experimental board. A slide rail is provided on the clamping station 220, and a slider matching the slide rail is located below the rear clamping block 224, slidably connected to the slide rail. A tension spring 225 connects the front clamping block 223 and the rear clamping block 224. A guide rod cylinder 221 for pushing and pulling the rear clamping block 224 is located at the center of the rotary table 210. An adjusting screw block 226 is fixed above the rear clamping block 224. A push-pull plate 222 is fixed to the output shaft of the guide rod cylinder 221, connected to the adjusting screw block 226. The extension and retraction of the output shaft of the guide rod cylinder 221 causes the rear clamping block 224 to move closer to or further away from the front clamping block 223, thereby clamping and releasing the experimental board.

[0052] The pushing assembly includes an active mechanism and an auxiliary mechanism. The active mechanism includes a moving platform 228, and a moving block 229 is slidably disposed above the moving platform 228. The moving block 229 can be driven by a cylinder. A lever 230 for pushing the clamping station 220 to rotate is fixed on the moving block 229. The auxiliary mechanism includes a telescopic cylinder 237. A second electromagnet 238 is fixed to the output end of the telescopic cylinder 237, and iron blocks 227 that are attracted to the second electromagnet 238 are fixed to the four side walls of the clamping station 220. First, the driving mechanism drives the moving block 229 to move towards the clamping station 220. The lever 230 contacts the clamping station 220 and drives the clamping station 220 to rotate counterclockwise. When it rotates to a certain angle, the output end of the telescopic cylinder 237 extends to a designated position, the second electromagnet 238 is energized and attracts the iron blocks 227 on the side walls of the clamping station 220, thereby realizing a 90° rotation of the clamping station 220.

[0053] The clamping station 220 has positioning holes 236 at each of its four corners. The locking assembly includes an upper connecting block 232 and a lower connecting block 233 located in the positioning holes 236. A connecting spring 234 is provided between the upper connecting block 232 and the lower connecting block 233. The rotary table 210 has four positioning slots corresponding to each part of the clamping station 220. The positioning slots are equipped with a first electromagnet 231 for engaging with the lower connecting block 233. When the first electromagnet 231 is energized, the lower connecting block 233 engages with the first electromagnet 231 under the tension of the connecting spring 234, thereby fixing the clamping station 220. When the first electromagnet 231 is de-energized, the lower connecting block 233 disconnects from the first electromagnet 231 and returns to its initial position under the tension of the connecting spring 234, thereby releasing the clamping station 220.

[0054] Automatic feeding module 300 is used to transport experimental plates with adhered crystals to rotating module 200;

[0055] The automatic feeding module 300 includes a horizontal transfer cylinder 320 and a horizontal transfer frame connected to the output end of the horizontal transfer cylinder 320. A lifting cylinder 330 is installed on the horizontal transfer frame, and a pneumatic gripper 310 is installed at the output end of the lifting cylinder 330. Since crystals are corrosive, the surface of the pneumatic gripper 310 is coated with a polytetrafluoroethylene coating. The polytetrafluoroethylene coating has good heat resistance and corrosion resistance, thereby improving the service life of the pneumatic gripper 310. The pneumatic gripper 310 grips the experimental plate and reaches the designated position of the fixed seat 235 under the combined action of the horizontal transfer cylinder 320 and the lifting cylinder 330.

[0056] The visual measurement module 700 includes a CCD camera 710, which is fixed in the vertical direction facing the experimental plate to be tested. It is used to measure the crystallization area of ​​the crystals on the experimental plate. Compared with the traditional method of manually measuring the crystallization area or limiting the size of the crystallization area, the method of measuring the area by machine vision reduces the operation difficulty of the experimenter and can also improve the accuracy of the measured area and the accuracy of the measurement results.

[0057] The automatic measurement module 800 is used to remove crystals from the experimental plate and obtain the maximum tangential adhesion force generated during the crystal removal process.

[0058] The automatic measurement module 800 includes an X-axis drive mechanism 850 and an X-axis translation stage 851 connected to the output end of the X-axis drive mechanism 850. A Y-axis drive mechanism 860 is mounted on the X-axis translation stage 851, and the output end of the Y-axis drive mechanism 860 is connected to the Y-axis translation stage 861. A Y-axis slide rail 862 and a Y-axis slider are provided between the X-axis translation stage 851 and the Y-axis translation stage 861. A Z-axis drive mechanism 870 is mounted on the Y-axis translation stage 861, and the output end of the Z-axis drive mechanism 870 is connected to the Z-axis translation stage 871. A Z-axis slide rail 872 and a Z-axis slider are provided between the Y-axis translation stage 861 and the Z-axis translation stage 871. A scraper 810 and a laser displacement sensor 830 are fixed on the Z-axis translation stage 871. An upper limit sensor 890 and a lower limit sensor 891 for limiting the movement of the scraper 810 are fixed on the Z-axis slide rail 872. A pressure sensor 820 is provided at the bottom of the scraper 810. First, the laser displacement sensor 830 measures the distance between the scraper 810 and the experimental board. The lower-level Arduino obtains the distance data measured by the laser displacement sensor 830 in real time and sends it to the upper-level Raspberry Pi for storage. The Raspberry Pi controls the X-axis drive mechanism 850, the Y-axis drive mechanism 860 and the Z-axis drive mechanism 870 to move the scraper 810 to contact the test surface of the experimental board. The Z-axis drive mechanism 870 drives the scraper 810 to remove the crystals. The pressure sensor 820 measures the maximum tangential adhesion force generated during the crystal removal process.

[0059] Several piezoelectric ceramic sheets 840 are fixed above the scraper 810. The two ends of the piezoelectric ceramic sheets 840 are connected to the positive and negative terminals of the power supply. The natural frequency of the crystal is obtained through modal analysis using ANSYS Workbench. The crystal will induce resonance at its natural frequency and the amplitude will be the largest. A high-frequency signal with the same magnitude as the natural frequency of the crystal is emitted by an ultrasonic generator and applied to the piezoelectric ceramic sheets 840. The piezoelectric ceramic sheets 840 will cause the crystal to vibrate at a high frequency, thereby removing the residual crystal on the surface of the scraper 810 after each measurement. This avoids experimental errors caused by residual crystal on the surface of the scraper 810 and improves the accuracy of the measurement results.

[0060] The data analysis and processing module 600 is electrically connected to the vision measurement module 700 and the automatic measurement module 800. The data analysis and processing module 600 includes a host computer (Raspberry Pi) and a slave computer (Arduino), used to store the crystal adhesion area acquired by the vision measurement module 700 and the tangential adhesion force measured by the automatic measurement module 800, and to calculate the adhesion strength of the crystals on each surface of the experimental board based on the crystal adhesion area and tangential adhesion force. The formula for calculating the adhesion strength is: Where F is the maximum thrust measured by pressure sensor 820 during the movement of scraper 810 to remove crystals, S is the adhesion area of ​​crystals on the experimental plate, and τ is the adhesion strength of crystals.

[0061] A measurement method using the above-mentioned automatic adhesion strength measurement system includes the following steps:

[0062] S1. The experimental plate material is placed regularly in the collector 420. Solid anhydrous aluminum trichloride crystals are added to the reactor 410. The crystals are heated to 180°C to sublimate and generate aluminum trichloride gas, which then forms crystals on the experimental plate.

[0063] S2. Start the automatic feeding module 300, and control the pneumatic gripper 310 to move to the top of the experimental plate to clamp and transfer it to the designated position of the clamping station 220 through the transverse cylinder and the lifting cylinder 330.

[0064] S3. The control system controls the output shaft of the guide rod cylinder 221 to retract, causing the rear clamping block 224 to move away from the front clamping block 223, releasing the pneumatic gripper 310 and placing the experimental plate in the fixed seat 235. The output shaft of the guide rod cylinder 221 extends, causing the rear clamping block 224 to approach the front clamping block 223 to clamp the experimental plate.

[0065] S4. As the rotary table 210 rotates, the experimental board is placed sequentially on several clamping stations 220 by the automatic feeding mechanism. The control system controls the first electromagnet 231 on the rotary table 210 to de-energize, causing it to disconnect from the lower connecting block 233 in the positioning hole 236.

[0066] S5. The moving block 229 pushes the lever 230 forward to make it move the clamping station 220 to rotate counterclockwise. The output shaft of the telescopic cylinder 237 extends, and the second electromagnet 238 is energized and attracts the iron block 227.

[0067] S6. The output shaft of the telescopic cylinder 237 returns to the initial position, and at the same time the second electromagnet 238 is de-energized. The control system controls the first electromagnet 231 on the rotary table 210 to be energized so that it attracts the lower connecting block 233 in the positioning hole 236, thereby fixing the clamping station 220.

[0068] S7. The vision measurement module 700 is positioned directly over the test surface of the experimental board and acquires the adhesion area of ​​crystals on the test surface. The obtained data is uploaded to the host computer Raspberry Pi in real time.

[0069] S8. The distance between the scraper 810 and the experimental plate is measured by the laser displacement sensor 830, and the scraper 810 is made to make accurate contact with the surface of the experimental plate by the X-axis drive mechanism 850, Y-axis drive mechanism 860 and Z-axis drive mechanism 870. The pressure sensor 820 obtains the maximum thrust of the scraper 810 during the cleaning process and uploads it to the host computer to calculate the adhesion strength of aluminum trichloride crystals.
