However, the speed, force, and angle of manual peeling cannot be synchronized and are highly arbitrary, resulting in a high rate of false measurements.

The film application platform includes a support table and a carrier slidably mounted to the support table. The carrier is used to fix the product to be tested with adhesive tape attached. The support table is provided with a peeling assembly and a photoelectric assembly. An adhesive tape clamping block is provided below the tensile sensor, used to fix one end of the adhesive tape adhered to the product to be tested. One side of the tensile sensor is connected to the front side of the support table via a displacement cable that passes around the photoelectric assembly. The longitudinal support assembly includes a lifting mechanism, used to drive the tensile sensor to reciprocate longitudinally above the peeling assembly.
[0007] The film application platform includes a first limiting member and a second limiting member; the first limiting member is located at the front end of the platform and is connected to the platform; the second limiting member is located at the rear end of the platform and the support platform and is connected to the support platform; and the peeling component is located between the first limiting member and the second limiting member.
[0008] The lifting mechanism includes a drive motor, a coupling, and a single-axis driver. The single-axis driver includes a ball screw and a drive slider. The drive motor is connected to the ball screw and the drive slider of the single-axis driver through the coupling. The tension sensor is connected to the drive slider.
[0009] The peeling assembly includes a side support block, an upper support block, a lower guide block, and a first knob. The upper support block is connected to the side support block. The first knob is located above the upper support block. The first knob passes through the upper support block and the lower guide block from top to bottom and is threadedly connected to the lower guide block.
[0010] The through-beam assembly includes: through-beam optical fiber, through-beam support block, grooved bearing, and bearing support frame; the grooved bearing is rotatably mounted on the bearing support frame, the bearing support frame is connected to the front end of the support platform, the through-beam support block is connected to the front end of the bearing support frame, the through-beam optical fiber is located on the top of the through-beam support block, the displacement cable passes through the bearing support frame and is rolledly assembled with the grooved bearing, and the displacement cable extending through the grooved bearing passes through the through-beam optical fiber and connects to the front side of the support platform.
[0011] The tape clamping blocks are arranged in pairs, each tape clamping block is constructed with an anti-stick structure, and there is a gap between the two tape clamping blocks for the tape to pass through.
[0012] The support platform is equipped with a positioning guide block on its side, and the platform has a positioning groove on its side. The positioning guide block matches and engages with the positioning groove to define the position of the platform.
[0013] The coating strength measuring device includes a control platform, wherein the film application platform and the longitudinal support assembly are both installed on the working plane of the control platform, and the control platform has a control panel, which is connected to the drive motor, the tension sensor and the through-beam fiber optic control respectively.

[0015] The present invention provides a measurement system, including the above-mentioned coating layer strength measuring device.
[0016] The technical solutions provided in this application have the following advantages compared with the prior art:
[0017] The coating strength measuring device and system provided in this application embodiment include a product to be tested with adhesive tape fixed to a platform. One end of the tape is fixed upwards to a tape clamping block below a tension sensor via a peeling assembly. One side of the tension sensor is connected to the front of the support platform via a displacement cable that passes around the through-beam assembly. It should be noted that the tape clamping block below the tension sensor allows the tape clamping block and the tension sensor to move synchronously upwards or downwards. When the lifting mechanism drives the tension sensor to reciprocate longitudinally above the peeling assembly, the displacement cable on one side of the tension sensor can pull the support platform forward via the through-beam assembly. For example, the through-beam assembly can be a through-beam optical fiber, which can accurately detect the state of the cable and also accurately detect the displacement changes between the tape or peeling assembly and the coating layer during the measurement and testing process. In this way, as the support platform moves forward, the tape adhered to the product under test is uniformly torn apart from it as the product under test moves forward with the support platform. Furthermore, guided by the peeling component, the tape moves vertically and uniformly with the tape clamping block. That is, as the product under test moves forward with the support platform, the tape clamping block can fix one end of the tape and pull it upward. During this process, the tension sensor can accurately measure the tension on the tape or other peeling tools in real time during the peeling of the coating layer, capturing the changes in tension with extremely high precision. This provides accurate raw data for calculating the bonding strength of the coating layer. Throughout the entire test, the changes in tension are continuously monitored, forming a curve of tension changing with time or displacement, further ensuring the accuracy of the coating layer measurement.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention.

Furthermore, reference numerals and / or letters may be repeated in different examples.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptions used in this text have been explained accordingly.
[0029] Existing methods for measuring film adhesion strength typically involve manually peeling off adhesive tape and performing multiple measurements to obtain accurate results. However, manual peeling involves inconsistent speed, force, and angle, leading to a high rate of false readings. Therefore, there is an urgent need for an automated device and system for measuring the adhesion strength of vacuum-deposited films that is convenient and highly accurate.
[0030] To alleviate the technical problem of high false measurement rate in the manual operation of coating strength measurement in the prior art, this application provides a coating strength measurement device that can maintain uniform force and high measurement accuracy during the coating measurement process through automated measurement equipment.
[0031] refer to Figures 1-3 This application provides a coating strength measuring device and system. The coating strength measuring device includes: a film application platform 1, a tensile sensor 2, and a longitudinal support assembly 3. The film application platform 1 includes a support table 11 and a platform 12 slidably assembled with the support table 11. The platform 12 is used to fix the product to be tested 13 with adhesive tape. The support table 11 is provided with a peeling assembly 14 and a photoelectric assembly 15. A tape clamping block 21 is provided below the tensile sensor 2. The tape clamping block 21 is used to fix one end of the tape bonded to the product to be tested 13. One side of the tensile sensor 2 is connected to the front side of the support table 11 via a displacement rope 22 that passes around the photoelectric assembly 15. The longitudinal support assembly 3 includes a lifting mechanism 31, which is used to drive the tensile sensor 2 to reciprocate in the longitudinal direction above the peeling assembly 14.
[0032] For example, the tension sensor 2 can accurately measure the tension of the tape or other peeling tool during the peeling of the coating layer in real time, capturing the changes in tension with extremely high precision, providing accurate raw data for calculating the bonding strength of the coating layer. Throughout the test, the changes in tension are continuously monitored, forming a curve of tension changing with time or displacement. Operators can observe the curve to understand the trend of the bonding strength of the coating layer during the peeling process, providing data basis.
[0033] This application does not limit the specific shape or structure of the platform 12 and the support platform 11, as long as the platform 12, on which the product to be tested 13 with adhesive tape is fixed, can slide along a preset position on the support platform 11, and the sliding path is a linear path.
[0034] For example, the peeling assembly 14 includes a peeling angle block, which can be configured as a wedge-shaped block or an angle block. Based on the shape of the peeling angle block, it can guide the coating layer to always move in the vertical direction relative to the tension sensor 2. That is, the guiding surface of the peeling angle block and the clamping surface of the tension sensor 2 remain in the same vertical plane region.
[0035] Based on relevant testing standards, using a 90° peel can make the peel force act more effectively on the interface between the coating layer and the substrate, avoiding force decomposition and complex stress state caused by angle deviation. Using 90° angle block parts can unify test conditions, and the consistent fixed position of the angle blocks can ensure the accuracy of the peel angle, improve test efficiency and accuracy, and reduce test costs. The tape is a consumable.
[0036] For example, the through-beam assembly 15 includes through-beam optical fiber 151, which can accurately detect the state of the displacement pull rope 22, and can also accurately detect the displacement change between the tape or peeling tool and the coating layer during the measurement and testing process.
[0037] For example, the longitudinal support component 3 includes a lifting mechanism 31, that is, the longitudinal support component 3 includes a structure that can be used to support the lifting mechanism 31, so that the lifting mechanism 31 can be kept stable during operation.
[0038] For example, by obtaining accurate bonding strength data, such as optical properties, corrosion resistance, and wear resistance, through the product under test 13, it can help determine whether the bonding strength meets the requirements, reflect the stability of the coating layer during long-term use, observe the changes of the coating layer on the product under test 13 under different temperature, humidity and other conditions, promptly identify problems in the coating process, and provide a basis for improving the coating process and improving product quality.
[0039] For example, the Z-axis motion is precisely converted into X-direction movement through the displacement rope 22, realizing one-axis control of movement in two directions, and converting it into synchronous movement with equal speed. This ensures that the tension applied during the test is uniform and stable, avoids sudden changes in force from interfering with the test results, and makes the test data more accurate.
[0040] Using the coating strength measuring device and system provided in this application embodiment, the product to be tested 13 with adhesive tape is fixed on the platform 12. One end of the tape is fixed upwards in the tape clamping block 21 below the tension sensor 2 via the peeling component 14. One side of the tension sensor 2 is connected to the front side of the support platform 11 via the displacement pull rope 22 passing around the through-beam assembly 15. It should be noted that the tape clamping block 21 is set below the tension sensor 2 so that the tape clamping block 21 and the tension sensor 2 can move upwards or downwards synchronously. When the lifting mechanism 31 drives the tension sensor 2 to move back and forth in the longitudinal direction above the peeling component 14, the displacement pull rope 22 on one side of the tension sensor 2 can pull the support platform 11 forward through the through-beam assembly 15. For example, the through-beam assembly 15 can be a through-beam optical fiber 151. The through-beam optical fiber 151 can accurately detect the state of the pull rope and can also accurately detect the displacement change between the tape or peeling component 14 and the coating layer during the measurement and testing process. In this way, as the support platform 11 moves forward, the tape adhered to the product under test 13 can be torn apart at a uniform speed while the product under test 13 follows the support platform 11 forward. Furthermore, guided by the peeling component 14, the tape can move vertically and uniformly with the tape clamping block 21. That is, as the product under test 13 moves forward with the support platform 11, the tape clamping block 21 can fix one end of the tape and pull it upward. During this process, the tension sensor 2 can accurately measure the tension on the tape or other peeling tools during the peeling of the coating layer in real time, capturing the tension change with extremely high precision, providing accurate raw data for calculating the bonding strength of the coating layer. Throughout the test, the change in tension is continuously monitored, forming a curve of tension change with time or displacement to further ensure the accuracy of the coating layer measurement.
[0041] Considering the possibility that the platform 12 will not detach from the support platform 11 during the relative sliding process, the coating strength measuring device provided in this application embodiment includes a first limiting member 16 and a second limiting member 17. The first limiting member 16 is located at the front end of the platform 12 and is connected to the platform 12. The second limiting member 17 is located at the rear end of the platform 12 and the support platform 11 and is connected to the support platform 11. The peeling component 14 is located between the first limiting member 16 and the second limiting member 17.
[0042] For example, the first limiting member 16 may be detachably connected to the front end of the platform 12, and / or the second limiting member 17 may be detachably connected to the rear end of the support platform 11.
[0043] For example, the first limiting member 16 may be threadedly connected to the front end of the platform 12, and / or the second limiting member 17 may be threadedly connected to the rear end of the support platform 11.
[0044] For example, the first limiting member 16 can be engaged with the front end of the platform 12, and / or the second limiting member 17 can be engaged with the rear end of the support platform 11.
[0045] For example, the first limiting member 16 can form a tenon-and-mortise structure with the front end of the platform 12, and / or the second limiting member 17 can engage with the rear end of the support platform 11.
[0046] Thus, with the first limiting member 16 in place, the platform 12 will not detach from the support platform 11 and collide with the front-side through-beam assembly 15; with the second limiting member 17 in place, the platform 12 will not detach from the rear of the support platform 11. Under the combined action of the first limiting member 16 and the second limiting member 17, the platform 12 can maintain its sliding movement on the support platform 11.
[0047] Considering the driving scheme of the lifting mechanism 31, in the coating layer strength measuring device provided in this application embodiment, the lifting mechanism 31 includes a drive motor 311, a coupling 312 and a single-axis driver 313. The single-axis driver 313 includes a ball screw and a drive slider. The drive motor 311 is connected to the ball screw and drive slider of the single-axis driver 313 through the coupling 312. The tension sensor 2 is connected to the drive slider.
[0048] Thus, by using a drive motor 311 to drive the ball screw and drive slider of the single-axis driver 313, the tension sensor 2 can be driven to reciprocate in the vertical direction (i.e., the Z-axis direction). The drive motor 311 can also be understood as a Z-axis motor. The Z-axis motor can accurately control the position and movement of the test sample or peeling tool in the vertical direction (Z-axis). The rotation of the Z-axis motor drives the pull rope moving carrier to achieve smooth and precise lifting, ensuring that the peeling process proceeds at the set speed and displacement, guaranteeing the accuracy and repeatability of the test. It can adapt to different testing needs; the lifting speed and stroke can be adjusted according to the characteristics of the coating layer and the testing requirements. It can meet the testing needs for coating layers of different thicknesses and hardnesses.
[0049] It should be noted that the Z-axis motor can maintain a constant tension during the peeling process, ensuring that the force acting on the coating layer remains stable throughout the peeling process. This eliminates the interference of force fluctuations on the test results, making the test results more accurately reflect the bonding strength of the coating layer. It can effectively reduce test errors caused by human factors and improve the accuracy of test data.
[0050] Considering the specific structural composition of the peeling component 14, in the coating layer strength measuring device provided in this application embodiment, the peeling component 14 includes a side support block 141, an upper support block 142, a lower guide block 143, and a first knob 144. The upper support block 142 is connected to the side support block 141, and the first knob 144 is located above the upper support block 142. The first knob 144 passes through the upper support block 142 and the lower guide block 143 from top to bottom, and is threadedly connected to the lower guide block 143.
[0051] For example, the peeling assembly 14 can be a detachable combination structure consisting of a side support block 141, an upper support block 142, a lower guide block 143 and a first knob 144, or it can be an integral structure consisting of the side support block 141, the upper support block 142, the lower guide block 143 and the first knob 144, depending on actual production needs.
[0052] Thus, the lower guide block 143 can be constructed as an angled block or a wedge-shaped block, and the aforementioned guide surface is formed on the lower guide block 143.
[0053] Considering the specific composition of the through-beam assembly 15, in the coating layer measuring device provided in this application embodiment, the through-beam assembly 15 includes: through-beam optical fiber 151, through-beam support block 152, grooved bearing 153, and bearing support frame 154; the grooved bearing 153 is rotatably mounted on the bearing support frame 154, the bearing support frame 154 is connected to the front end of the support platform 11, the through-beam support block 152 is connected to the front end of the bearing support frame 154, the through-beam optical fiber 151 is located on the top of the through-beam support block 152, the displacement rope 22 passes through the bearing support frame 154 and is rolledly assembled with the grooved bearing 153, and the displacement rope 22 extending through the grooved bearing 153 passes through the through-beam optical fiber 151 and is connected to the front side of the support platform 11.
[0054] In this way, the grooved bearing 153 can guide the displacement rope 22, and at the same time, the grooved bearing 153 can also provide a sliding track for the displacement rope 22; the opposing support block 152 is connected to the front end of the bearing support frame 154, so as to detect the movement accuracy of the displacement rope 22 after the displacement rope 22 turns 90°.
[0055] Considering the specific composition of the tape clamping block 21, in the coating layer strength measuring device provided in this application embodiment, the tape clamping blocks 21 are arranged in pairs, each tape clamping block 21 is constructed as an anti-stick structure, and there is a hole between the two tape clamping blocks 21 for the tape to pass through.
[0056] For example, the tape clamping block 21 can firmly fix the test tape in the designated position, preventing the tape from shifting, loosening or falling off during the test, ensuring that the contact position and pressure between the tape and the coating layer remain stable. The tape clamping block 21 is easy to install and disassemble, with a simple structural design, which allows operators to quickly install the tape before the test and replace the tape in time after the test. It works in conjunction with the Z-axis lifting mechanism 31 to peel off the tape after the tape is clamped, in coordination with the movement of the Z-axis, ensuring the smooth progress of the entire test process.
[0057] In this way, the tape clamping block 21 with the non-stick structure can prevent the tape (i.e. the coating layer) from sticking to the tape clamping block 21, thereby ensuring that the tape can always maintain a vertical movement along the Z direction.
[0058] Considering the stability of the initial positioning of the stage 12 relative to the support stage 11, in the coating strength measuring device provided in this application embodiment, a positioning guide block 4 is installed on the side of the support stage 11, and a positioning groove 121 is provided on the side of the stage 12. The positioning guide block 4 matches and engages with the positioning groove 121 to limit the limited position of the stage 12.
[0059] Thus, after the coating layer is glued to the product to be tested 13, the end of the coating layer (i.e. the tape) that extends out needs to be turned 90° by the peeling component 14. The end of the coating layer that extends out needs to be positioned in the tape clamping block 21. This process requires the product to be in a relatively fixed position so as to ensure that the tape remains vertical in the Z direction.
[0060] Considering the automatic start-up or signal transmission scheme of the corresponding device in the embodiments of this application, the coating strength measuring device provided in the embodiments of this application includes: a control platform 5, a film application platform 1 and a longitudinal support component 3, all of which are installed on the working plane 51 of the control platform 5. The control platform 5 has a control panel 52, which is electrically connected to the drive motor 311, the tension sensor 2 and the through-beam optical fiber 151 respectively.
[0061] For example, the control platform 5, also known as the circuit control box, introduces external power input into the control box and distributes it to various electrical components through the internal circuit system, providing a stable power supply for the equipment's motors, sensors, controllers, etc., to ensure the normal operation of the equipment. At the same time, the control panel 52 is equipped with operating elements such as buttons and switches, which facilitates operators to start, stop, adjust speed, and switch working modes of the equipment.
[0062] In this way, the control platform 5 can directly provide power to the corresponding devices, and at the same time control the execution instructions of the corresponding devices.
[0063] Considering the visualization scheme of measurement data, the coating layer strength measuring device provided in this application embodiment includes an industrial control computer 6 and a display screen 7, with the industrial control computer 6 electrically connected to the display screen 7 and the control platform 5 respectively.
[0064] For example, the industrial control computer 6 is used for data acquisition, accurately collecting various types of data, analyzing and processing the collected data, calculating average values, standard deviations, motion curve analysis, etc., storing important test data, and uploading it to the company's MES management system via Ethernet communication to achieve data sharing and remote monitoring, making it convenient for personnel to remotely understand the equipment's operating status and perform remote operation and management.
[0065] For example, the display screen 7, which can also be understood as a monitor, is used to display test operation parameters, such as tension, speed, angle, etc., in an intuitive curve or digital form on the display screen 7, so that the operator can observe and understand the equipment operation status at any time, so as to make timely adjustments and operations.
[0066] This application also provides a measurement system, including the above-mentioned coating strength measuring device, which can achieve all the effects of the coating strength measuring device, and will not be described in detail here.
[0067] The coating strength measuring device and system according to the embodiments of this application can be used to deploy the test environment according to the following steps:
[0068] 1. Take a number of samples to be tested and manually attach the samples to the surface of the adhesive carrier. The samples to be tested should not overlap on the carrier and should be placed in different intervals.
[0069] 2. Apply the tape to the surface of the product to be tested. To ensure good contact between the tape and the vacuum coating layer, use an eraser to press the tape back and forth until the tape is visually completely adhered to the vacuum coating layer. After applying the tape, let the test sample stand for 5 minutes.
[0070] 3. Place the carrier with the test sample attached by tape into the positioning platform of the testing machine, tighten the screws on both sides of the platform to fix the carrier in place, ensuring there is no looseness.
[0071] 4. Straighten the tape with a blank length of about 200mm and pass it through the Z-axis clamping block. Manually tighten the screw to fix the tape through the clamping device. Visually check whether the tape is straight and whether it is bent to determine the initial position.
[0072] 5. Visually inspect whether the displacement pull rope 22 is straight or bent, confirm whether the through-beam fiber optic cable 151 is in working condition, and check for any other abnormalities or alarms on the human-machine interface.
[0073] Following the steps above, once ready, press the start button. The Z-axis servo motor (i.e., drive motor 311) rotates, driving the lead screw to rise at a constant speed, pulling the carrier in the X direction at a constant speed via the pull rope. As the height distance increases, the tape begins to completely peel off from the product being tested. After the test, the collected tension and speed data are converted into a graph and stored.
