Description

Technical Field

[0001] This utility model relates to the field of adhesion testing technology, specifically to a device for testing the peel adhesion of FEP tape. Background Technology

[0002] The FEP tape peel adhesion tester is used to measure the adhesion force between FEP (fluorinated ethylene propylene copolymer) tape and the substrate. During the test, one end of the FEP tape sample is fixed with a clamp, and the other end is pasted onto the substrate. Then, the tape is pulled at a set speed to peel it off the surface of the substrate. The force sensor will sense and measure the magnitude of this pulling force in real time to test the adhesion force. The data acquisition and processing system collects the pulling force data in real time until the tape is completely peeled off from the substrate.

[0003] The clamps used to pull FEP tape samples generally require manual clamping by the tester. The operator needs to fix each tape in the clamp one by one, which is relatively time-consuming. For batch testing, slow clamping speed will seriously affect testing efficiency and increase the testing cycle. Moreover, the operator needs to frequently perform operations such as picking up, placing, adjusting and fixing. Especially in long-term or large-scale testing of samples, the operator is prone to fatigue, which may lead to a decrease in clamping quality and further affect the test results. Utility Model Content

[0004] The purpose of this invention is to provide an FEP tape peel adhesion force testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an FEP tape peel adhesion force testing device, comprising a testing device body, an object to be adhered to, an FEP tape sample, and a force sensor. A fixed clamp is provided at the bottom of the testing device body, and the object to be adhered to is clamped inside the fixed clamp. An FEP tape sample is adhered to one side of the object to be adhered to. A movable clamp is provided inside the testing device body above the FEP tape sample, and a cylinder is provided at the center of the top of the movable clamp. A lifting block is provided at the output end of the cylinder, and movable plates are evenly connected to both sides of the lifting block via connecting rods. Clamping plates are provided at the bottom ends of the movable plates. A lead screw is provided on one side of the testing device body, and a driving block is sleeved on the lead screw. A lifting seat is fixed to one side of the driving block, and the lifting seat is connected to the movable clamp via a force sensor. A drive motor is fixed to one end of the top of the testing device body, and the output end of the drive motor is connected to the lead screw.

[0006] Preferably, a guide rod is provided on the side of the main body of the testing device away from the lead screw, and a guide sleeve is provided on the side of the lifting seat away from the drive block, which can effectively limit the movement direction of the lifting seat and reduce its swaying and deviation during the up and down movement.

[0007] Preferably, a temperature sensor is installed on one side of the main body of the testing device, and one end of the main body of the testing device is connected to a door via a hinge, which can monitor the internal ambient temperature in real time. With the door, it is convenient to observe the testing process and can effectively isolate external environmental interference.

[0008] Preferably, a temperature control chamber is provided at the top of the main body of the testing device, and a fan is provided at the top of the temperature control chamber. An electric heating wire is provided at the bottom of the temperature control chamber, and an air outlet grille is provided at the bottom of the temperature control chamber. This allows for rapid and precise adjustment of the test environment temperature, simulating different temperature conditions and making the test results more consistent with actual usage scenarios.

[0009] Preferably, a filter screen is provided at the top of the temperature control chamber, and slide rails are provided on both sides of the filter screen. Slide grooves matching the slide rails are provided on both sides of the temperature control chamber, which can effectively filter impurities in the air and prevent them from affecting the test environment.

[0010] Preferably, the movable clamp has guide grooves at both ends near the movable plate, and the movable plate is connected to the guide groove via guide blocks on the side near the guide groove. This can accurately guide the movement trajectory of the movable plate, so that the clamping plate is subjected to uniform force when clamping the tape sample, and avoid uneven clamping force caused by position deviation.

[0011] Preferably, the clamping plate has anti-slip protrusions evenly distributed on the side near the FEP tape sample, and the anti-slip protrusions are all made of silicone material, which can greatly increase the friction between the clamping plate and the FEP tape sample, and effectively prevent the tape from sliding or shifting during clamping and peeling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This FEP tape peel adhesion force testing device consists of a main body, a fixed clamp, an object to be adhered to, an FEP tape sample, a movable clamp, a cylinder, a lifting block, connecting rods, a movable plate, and a clamping plate. The cylinder drives the lifting block to move upward, and the connecting rods on both sides pull the movable plate closer together, thereby causing the clamping plate to automatically clamp the upper end of the FEP tape sample. This allows for the clamping operation of the FEP tape sample to be completed in a short time, greatly saving clamping time. Especially when conducting batch testing, it can significantly improve the overall testing efficiency and shorten the testing cycle. The operator only needs to attach the FEP tape sample to the object to be adhered to and then start the cylinder to complete the clamping action, reducing the labor intensity of the operator and reducing clamping errors and delays caused by human factors.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-5 An embodiment of this utility model is provided: an FEP tape peel adhesion force testing device, including a testing device body 1, an object to be adhered to 3, an FEP tape sample 4 and a force sensor 17. A fixed clamp 2 is provided at the bottom of the testing device body 1, and the object to be adhered to is clamped inside the fixed clamp 2. The FEP tape sample 4 is adhered to one side of the object to be adhered to.

[0022] The object to be bonded 3 is clamped in the fixed clamp 2 at the bottom of the main body 1 of the test device and fixed in place. The FEP tape sample 4 is then attached to one side of the object to be bonded 3.

[0023] A movable clamp 13 is provided inside the main body 1 of the test device above the FEP tape sample 4, and a cylinder 14 is provided at the center of the top of the movable clamp 13. A lifting block 18 is provided at the output end of the cylinder 14, and movable plates 15 are evenly connected to both sides of the lifting block 18 through connecting rods 19. A clamping plate 16 is provided at the bottom of each movable plate 15.

[0024] Adjust the movable clamp 13 above the FEP tape sample 4 so that the clamping plate 16 is located on both sides of the FEP tape sample 4. Start the cylinder 14. The output end of the cylinder 14 pulls the lifting block 18 upward. The two sides of the lifting block 18 are evenly pulled by the connecting rod 19 to bring the movable plate 15 closer to each other. The clamping plate 16 at the bottom of the movable plate 15 also moves closer, automatically clamping the upper end of the FEP tape sample 4.

[0025] The movable clamp 13 has guide grooves 21 at both ends near the movable plate 15. The movable plate 15 is connected to the guide groove 21 via guide blocks on the side near the guide groove 21 to ensure the accuracy of the movement of the movable plate 15.

[0026] The clamping plate 16 has anti-slip ridges 20 evenly arranged on the side near the FEP tape sample 4, and the anti-slip ridges 20 are all made of silicone material, which can effectively prevent the tape from sliding during clamping and testing.

[0027] This allows the movable clamp 13 to automatically clamp the upper end of the FEP tape sample 4, enabling the clamping operation of the FEP tape sample 4 to be completed in a short time, greatly saving clamping time. Especially when conducting batch testing, it can significantly improve the overall testing efficiency and shorten the testing cycle. The operator only needs to attach the FEP tape sample 4 to the object to be adhered 3 and then start the cylinder 14 to complete the clamping action, reducing the labor intensity of the operator and reducing clamping errors and delays caused by human factors.

[0028] A lead screw 10 is provided on one side inside the main body 1 of the testing device, and a drive block 11 is sleeved on the lead screw 10. A lifting seat 5 is fixed on one side of the drive block 11, and the lifting seat 5 is connected to the moving clamp 13 through a force sensor 17. A drive motor 9 is fixed at one end of the top of the main body 1 of the testing device, and the output end of the drive motor 9 is connected to the lead screw 10.

[0029] Start the drive motor 9, which drives the lead screw 10 to rotate, causing the drive block 11, the lifting seat 5 and the moving clamp 13 to move upward. The moving clamp 13 drives the clamped FEP tape sample 4 to move upward, gradually peeling it off from the surface of the adhered object 3.

[0030] During the peeling process, the force sensor 17 measures and records the tensile force data borne by the tape in real time. After the test is completed, the force sensor 17 transmits the measured tensile force data to the data processing system for analysis and processing, such as calculating the average value and the maximum value, so as to obtain the peel adhesion force value of FEP tape sample 4.

[0031] A temperature sensor 6 is installed on one side inside the main body 1 of the testing device. A temperature control box 7 is installed at the top inside the main body 1 of the testing device. A fan 8 is installed at the top of the temperature control box 7. A heating wire 23 is installed at the bottom inside the temperature control box 7. An air outlet grille 24 is installed at the bottom of the temperature control box 7.

[0032] If testing is required in a specific temperature environment, the fan 8 at the top of the temperature control chamber 7 and the heating wire 23 at the bottom of the temperature control chamber 7 can be turned on. The fan 8 draws air into the temperature control chamber 7, where it comes into contact with the heating wire 23 and is heated. The heated air is then blown into the main body 1 of the test device through the air outlet grille 24 at the bottom of the temperature control chamber 7.

[0033] A temperature sensor 6 installed on one side inside the main body 1 of the testing device monitors the temperature inside the main body 1 of the testing device in real time. Based on the temperature feedback, the heating power of the heating wire 23 and the speed of the fan 8 are controlled to adjust the temperature inside the main body 1 of the testing device to the set value. By controlling the temperature during the test, the performance of the FEP tape sample 4 in the actual use environment can be simulated, making the test results more practical and valuable.

[0034] A filter 22 is installed at the top of the interior of the temperature control chamber 7. The air is filtered by the filter 22 at the top of the interior of the temperature control chamber 7 to avoid contaminating the test environment. Slide rails 25 are provided on both sides of the filter 22. Slide grooves matching the slide rails 25 are opened on both sides of the interior of the temperature control chamber 7 to facilitate the installation and removal of the filter 22.

[0035] One end of the main body 1 of the testing device is connected to a door 12 via a hinge, so that the main body 1 of the testing device can be closed for testing;

[0036] The specific models and specifications of temperature sensor 6, drive motor 9, force sensor 17, cylinder 14, and heating wire 23 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail here.

[0037] Working principle: In this embodiment, the object to be adhered 3 is clamped and fixed in the fixed clamp 2 at the bottom of the main body 1 of the testing device. The FEP tape sample 4 is then attached to one side of the object to be adhered 3. The drive motor 9 at the top of the main body 1 of the testing device is started. The output end of the drive motor 9 drives the lead screw 10 to rotate. The drive block 11 sleeved on the lead screw 10 moves along the lead screw 10, thereby driving the lifting seat 5 fixedly connected to one side of the drive block 11 to rise or fall. The moving clamp 13 is adjusted to a suitable initial position, that is, the moving clamp 13 is located at a suitable distance above the FEP tape sample 4. The cylinder 14 at the center of the top of the moving clamp 13 is then started. The output end pushes the lifting block 18 upward. The lifting block 18, with its two sides evenly connected by the connecting rod 19, pulls the movable plate 15 closer together. The clamping plate 16 at the bottom of the movable plate 15 then moves closer, automatically clamping the upper end of the FEP tape sample 4. The guide grooves 21 on both ends of the movable clamp 13 near the movable plate 15 cooperate with the guide blocks on the side of the movable plate 15 near the guide grooves 21, ensuring the accuracy of the movable plate 15's movement. Simultaneously, because the clamping plate 16 has evenly distributed silicone anti-slip ridges 20 on the side near the FEP tape sample 4, it effectively prevents the tape from slipping during clamping and testing. The drive motor 9 is then restarted, causing the lead screw 10 to rotate. The drive block 11, lifting seat 5, and moving clamp 13 move upwards, causing the FEP tape sample 4 to move upwards and gradually peel off from the surface of the adherend 3. During the peeling process, the force sensor 17 measures and records the tensile force data of the tape in real time. After the test is completed, the force sensor 17 transmits the measured tensile force data to the data processing system for analysis and processing, such as calculating the average value and the maximum value, to obtain the peel adhesion force value of the FEP tape sample 4. In addition, if testing is required in a specific temperature environment, the fan 8 at the top of the temperature control chamber 7 and the heating wire 23 at the bottom of the temperature control chamber 7 can be activated. The fan 8 will... Air is drawn into the temperature control chamber 7 and first filtered through a filter 22 located at the top of the chamber. The filtered air then comes into contact with the heating wire 23 and is heated. The heated air is then blown into the main body 1 of the testing device through the air outlet grille 24 at the bottom of the chamber 7. A temperature sensor 6 located on one side of the main body 1 monitors the temperature inside the main body 1 in real time. Based on the temperature feedback, the heating power of the heating wire 23 and the speed of the fan 8 are controlled to adjust the temperature inside the main body 1 to the set value. By controlling the temperature during the test, the performance of the FEP tape sample 4 in the actual use environment can be simulated, making the test results more practically valuable.
