Description

Technical Field

[0001] The utility model relates to the field of material testing, and more precisely to a device for measuring the shear strength of materials and the peeling force of coatings. Background Art

[0002] When testing the peel strength of a coating, the product is first manually removed and the surface is cleaned of dust. After cleaning, the tape is applied. Care is taken to avoid bubbles during application, as these will affect the test results. After application, the tape is rolled with a special pressure roller. After rolling, the product and tape are fixed to the peel strength test equipment for testing.

[0003] The shortcomings of this testing method are that the tape is applied manually, and the pressure applied varies with each application, resulting in different peel force results. The measurement requires a large sample area, and multiple tests cannot be performed on the same sample, wasting material. Furthermore, this method only measures the peel strength between the coating and the substrate, not the shear strength of coatings at different depths. Peel and shear strength require separate equipment, making testing inconvenient, inaccurate, and with poor repeatability. The results are difficult to reproduce, and the testing cost is high.

Rotating the knob drives the stopper forward and backward, thereby driving the second arc-shaped adjustment portion of the second plane adjustment platform to move, thereby adjusting the tilt angle in the forward and backward directions.

[0115] The first plane adjustment mechanism and the second plane adjustment mechanism can be adjusted manually, such as Figure 4-7 As shown, the motor 29 can also be used to drive the motor, so that the adjustment is automatically performed by the motor. Figure 8 shown.

[0116] By adjusting the second plane adjustment platform along the second arc-shaped adjustment portion via the second plane adjustment mechanism, the left-right tilt angle of the second plane adjustment platform relative to the second plane adjustment base can be adjusted. Thus, by adjusting the front-to-back tilt angle and the left-to-right tilt angle, the front-to-back tilt angle and the left-to-right tilt angle of the second plane adjustment platform can be adjusted, thereby causing the sample placement platform to tilt in the front-to-back and left-to-right directions, thereby adjusting the levelness of the sample placement platform.

[0117] The method for adjusting the level of the test bench is as follows:

[0118] The scraper is replaced with a special test head with a spherical bottom, and the level is adjusted according to the feedback of the Z-axis force sensor and the Z-axis displacement sensor 6.

[0119] Set the pressure in the Z-axis direction to a fixed value in the program, move the test head to the four corners A, B, C, and D of the sample placement table respectively, and use the Z-axis drive mechanism 4 to drive the test head down. Observe at A, B, C, and D whether the numerical difference of the displacement in the Z-axis direction is within the allowable range when the pressure in the Z-axis direction reaches the set value. If it exceeds the range, continue to adjust the first plane adjustment mechanism and the second plane adjustment mechanism.

[0120] When electric adjustment is used, the levelness of the sample placement table can be adjusted according to program calculations.

[0121] In order to capture the state of the material to be tested during the movement of the scraper so as to analyze the material based on the captured images, the device for measuring the shear strength and coating peeling force of the material also includes a main camera device 8 provided on the frame; the main camera device 8 includes a main camera mount 81 provided on the frame and a main camera 82 provided on the main camera mount, and the main camera is set toward the scraper.

[0122] The main camera mount 82 includes a backing plate 821, a base 822, a front-to-back adjustment device 823, a support frame 824, an up-and-down adjustment device 825, and a front-to-back angle adjustment device 826.

[0123] A backing plate 821 is mounted on the frame and can move forward and backward relative to the frame. A circular arc-shaped angle adjustment portion 8211 is provided on the top surface of the backing plate, with the center of the arc facing the test bench. In this embodiment, the angle adjustment portion is a groove. The frame is provided with a front-to-back guide rail 80, along which the backing plate moves forward and backward. Once in place, it is locked in place with screws.

[0124] The base 822 is mounted on the base plate and is movable along the angle adjustment portion. A slide post inserted into the angle adjustment portion can be provided on the base, allowing the base to slide along the angle adjustment portion via the slide post. This allows the main camera's shooting angle to be adjusted. Of course, the base can also be replaced with an automatic adjustment mechanism instead of manual adjustment, allowing the main camera to be moved to the desired viewing position through program control.

[0125] The front-back adjustment device 823 is provided on the base and can adjust the front-back position of the main camera. The front-back adjustment device can be implemented by a structure similar to the Y-axis adjustment device of the XY-axis adjustment device 24.

[0126] The support frame 824 is arranged on the front-rear adjustment device and can move forward and backward under the drive of the front-rear adjustment device.

[0127] The up and down adjustment device 825 is provided on the support frame and can adjust the up and down position of the main camera. The up and down adjustment device 825 can be implemented by a structure similar to the Z-axis drive mechanism 4.

[0128] The front-back angle adjustment device 826 is provided between the main camera and the up-down adjustment device and can adjust the front-back tilt angle of the main camera. The front-back angle adjustment device can be implemented using a structure similar to that used in the horizontal adjustment device to adjust the front-back tilt angle.

[0129] The main camera can be realized by a high-precision CCD camera, which has the following functions:

[0130] 1. The image can be magnified to help observe the test process, whether the scraper reaches the desired cutting position and the shape of the material during cutting.

[0131] 2. Record the cutting process to leave influencing data for subsequent analysis of the shear strength and peel strength of the material.

[0132] 3. It can automatically measure the size of the scraper blade. The width of the scraper blade edge is an important parameter for calculating shear strength and peel strength. The size of the scraper blade edge can be automatically obtained through a high-precision CCD camera.

[0133] 4. The CCD camera can be used to confirm again whether the blade edge is parallel to the material.

[0134] In this specific embodiment, an additional camera device can be provided to better capture the material to be tested from multiple angles. The device for measuring the shear strength and coating peeling force of a material also includes a secondary camera device 9, which has the same function as the main camera device. The secondary camera device 9 includes a housing 91, an arc-shaped bracket 92, a bracket seat 93, and a secondary camera 94.

[0135] The housing 91 is arranged on the frame.

[0136] The arc-shaped bracket 92 is disposed on the housing and is located above the scraper.

[0137] The bracket seat 93 is disposed on the arc-shaped bracket and can move along the arc-shaped bracket.

[0138] The auxiliary camera 94 is disposed on the bracket and is disposed toward the scraper.

[0139] Of course, only the main camera device or the auxiliary camera device may be provided according to actual needs.

[0140] The equipment for measuring the shear strength of materials and the peeling force of coatings can be set with the shear strength test degree and the coating peeling strength test program. During the test, the corresponding test programs can be started respectively for testing.

[0141] When testing the shear strength of a material, the material testing method of the present invention utilizes the above-mentioned equipment for measuring the shear strength of the material and the peeling force of the coating to perform the test. The material testing method includes:

[0142] Step 1: Set the peeling depth to be tested in the program.

[0143] Step 2: Adjust the level of the test bench and fix the material to be tested on the test bench.

[0144] Step 3: Start the shear strength test. The Z-axis drive mechanism and the Y-axis drive mechanism move the scraper to the initial test position of the material to be tested. At this time, the scraper contacts the surface of the material to be tested, the value of the Z-axis force sensor is 0, and the Z-axis displacement sensor and the Y-axis displacement sensor are set to zero.

[0145] Step 5: The Z-axis drive mechanism and the Y-axis drive mechanism move simultaneously at the set speed. When the Z-axis displacement sensor detects that the value reaches the shear depth, the Z-axis drive mechanism stops driving to keep the scraper at the shear depth. The Y-axis drive mechanism continues to drive the scraper to the set position and then stops. During this process, the Z-axis force sensor, Y-axis force sensor, Z-axis displacement sensor, and Y-axis displacement sensor respectively collect the force in the up and down directions of the scraper, the force in the front and back directions of the scraper, the displacement in the up and down directions of the scraper, and the displacement in the front and back directions of the scraper.

[0146] Step 6: Calculate the shear strength based on the forces acting on the blade in the up-and-down direction, the forces acting on the blade in the front-and-rear direction, the displacement of the blade in the up-and-down direction, and the displacement of the blade in the front-and-rear direction.

[0147] The forces on the blade in the up-down direction, the forces on the blade in the front-back direction, the displacements on the blade in the up-down direction, and the displacements on the blade in the front-back direction are plotted as follows: Figure 9 The test software identifies a stable shear strength range, and the program automatically calculates the shear force within this range based on parameters such as horizontal force (i.e., the force acting on the blade in the front-to-back direction), vertical force (i.e., the force acting on the blade in the top-to-bottom direction), and blade size.

[0148] After the test is completed, the blade is reset.

[0149] When testing the coating peel strength, the material testing method of the present invention can also be tested using the above-mentioned equipment for measuring material shear strength and coating peel force. The material testing method includes:

[0150] Step 1: Adjust the level of the test bench and fix the material to be tested on the test bench.

[0151] Step 2: Start the peel strength test. The Z-axis drive mechanism and the Y-axis drive mechanism move the scraper to the initial test position of the material to be tested. At this time, the scraper contacts the surface of the material to be tested, the value of the Z-axis force sensor is 0, and the Z-axis displacement sensor and the Y-axis displacement sensor are set to zero.

[0152] Step 3: The Z-axis drive mechanism and the Y-axis drive mechanism move simultaneously at the set speed. When the coating and the substrate are peeled off, the Z-axis drive mechanism stops driving to keep the scraper at the current peeling depth. The Y-axis drive mechanism continues to drive the scraper to the set position and then stops. During this process, the Z-axis force sensor, Y-axis force sensor, Z-axis displacement sensor, and Y-axis displacement sensor respectively collect the force in the up and down directions of the scraper, the force in the front and back directions of the scraper, the displacement in the up and down directions of the scraper, and the displacement in the front and back directions of the scraper.

[0153] The CCD camera can clearly observe the scene when the coating is peeling off. The program can recognize the characteristics of the peeling, feed it back to the program, and record the time. The peeling start position can be shown in the peeling force curve. Figure 11 A schematic diagram showing the scene from blade contact to coating peeling.

[0154] When the coating peels from the substrate, the horizontal force value drops sharply, and the peeling phenomenon can be observed on the CCD camera. In the test software, the point where the horizontal force drops sharply and the peeling start time reported by the CCD camera can be used to accurately determine the starting point of the peeling between the coating and the substrate, and the peel strength of the coating can be calculated.

[0155] Step 4: Calculate the peel strength of the coating based on the force applied to the scraper in the up-and-down direction, the force applied to the scraper in the front-and-back direction, the displacement of the scraper in the up-and-down direction, and the displacement of the scraper in the front-and-back direction.

[0156] According to the force on the blade in the up-down direction, the force on the blade in the front-back direction, the displacement of the blade in the up-down direction, and the displacement of the blade in the front-back direction, the following diagram is drawn: Figure 10 The program automatically calculates the peel strength based on parameters such as horizontal force (i.e., the force applied to the front and back of the blade) and vertical force (i.e., the force applied to the top and bottom of the blade).

[0157] After the test is completed, the blade is reset.

[0158] The utility model discloses an equipment for measuring the shear strength and peeling force of materials by setting a frame, a test bench, a scraper, a Z-axis driving mechanism, a Y-axis driving mechanism, a Z-axis force sensor, a Y-axis force sensor, a Z-axis displacement sensor, and a Y-axis displacement sensor; the Z-axis driving mechanism and the Y-axis driving mechanism are used to drive the scraper to move in the up-down direction and the front-back direction; the Z-axis force sensor, the Y-axis force sensor, the Z-axis displacement sensor, and the Y-axis displacement sensor are used to respectively collect the force in the up-down direction, the force in the front-back direction, the displacement in the up-down direction, and the displacement in the front-back direction of the scraper; thus, the scraper can be used to cut the material; the shear strength or peeling strength is tested by collecting the force in the up-down direction, the force in the front-back direction, the displacement in the up-down direction, and the displacement in the front-back direction of the scraper; not only is the test process convenient, but also the test accuracy is high, the test data has good repeatability, the test results are reproducible, the test efficiency is high, and the cost is low.
