Description

Technical Field

[0001] This utility model relates to a coating layer peel test device, specifically a coating layer peel strength test device for coated products. Background Technology

[0002] The coating layer of a coated product is one or more thin films covering the surface of a substrate. It is usually formed by physical or chemical deposition of materials such as metals, ceramics, and polymers. Peel strength testing is performed on the coating layer of a coated product. Peel strength is one of the key indicators for measuring the quality of coated products. Through testing, it is possible to effectively determine whether the adhesion performance between the coating layer and the substrate meets the design and usage requirements, ensuring the stable and reliable quality and performance of the product.

[0003] Currently, peel strength testing is conducted using a universal testing machine or a dedicated peel strength tester. One end of the sample is fixed to the clamp of the testing machine, and the other end is fixed to a movable clamp. Then, the angle of the sample is adjusted so that it forms a 90-degree angle with the substrate, thereby pulling one end of the coating to test its peel strength.

[0004] During the 90° rotation peel test, because the position of the clamp is fixed, when one end of the film is pulled, the clamp lacks the force to pull the film upward, which makes it impossible to straighten the film during the peel test. The film is prone to curling, which leads to uneven stress distribution and additional bending moment, thus affecting the accuracy of the peel strength test and making the test results unable to truly reflect the adhesion strength between the film and the substrate. Summary of the Invention

[0005] The purpose of this invention is to provide a film peel strength testing device for coated products, in order to solve the problem mentioned in the background art that when one end of the film is pulled, the clamp lacks the force to pull the film upward, which makes it impossible to straighten the film during the peel test. The film is prone to curling, which leads to uneven stress distribution and additional bending moment, thus affecting the accuracy of the peel strength test and making the test results unable to truly reflect the adhesion strength between the film and the substrate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A film peel strength testing device for coated products includes a test bench, a control panel, and a crossbeam support. The top of the test bench is provided with a clamping platform and a support. One side of the support is provided with a pressing platform and a support base for fixing one side of the film layer. A rotating shaft and a rotating arm are rotatably mounted on the support base. The rotating arm has a cavity and a slot. A transmission mechanism and a threaded adjustment mechanism that cooperates with the transmission mechanism are provided on the rotating arm. A support rotation mechanism is provided on one side of the support base.

[0007] The film peel strength testing device for the coated product as described above: the transmission mechanism includes a screw rotatably mounted on the cavity and a transmission tooth sleeved at the end of the screw, the end of the screw extending through to one side of the rotating arm.

[0008] The film peel strength testing device for the coated product as described above: the transmission mechanism further includes a semi-circular toothed disc disposed on the top of the support base, the semi-circular toothed disc meshing with the transmission teeth.

[0009] The film peel strength testing device for coated products as described above: the threaded adjustment mechanism includes a threaded block threaded on the screw, and the threaded block is slidably mounted on the slot.

[0010] The film peel strength testing device for the coated product as described above: the thread adjustment mechanism further includes a support mechanical arm disposed at the bottom of the thread block and a mechanical claw disposed on the support mechanical arm for gripping the film layer, the mechanical claw being disposed on one side of the clamping table.

[0011] The film peel strength testing device for the coated product as described above: the supporting rotation mechanism includes a rotating guide frame disposed on one side of the support and an arc-shaped groove formed on the rotating guide frame, and cylinders are disposed on both sides of the rotating arm, the cylinders sliding on the arc-shaped groove.

[0012] The film peel strength testing device for the coated product as described above: the support rotation mechanism includes a motor disposed on one side of the support base, and the output shaft of the motor is fixed to the rotation shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: through the coordinated cooperation of the transmission mechanism and the thread adjustment mechanism, the clamp extends outward during the rotation and peeling process, which can straighten the film layer and prevent the film layer from curling. This avoids problems such as uneven stress distribution and additional bending moment caused by curling, thereby improving the accuracy of peel strength test and making the test results more realistically reflect the true adhesion strength between the film layer and the substrate.

[0014] This invention also enables a 90° rotation peel test, which accurately simulates the stress conditions of the film layer in actual applications, improves the effectiveness and accuracy of the test results, and facilitates the correct evaluation of the adhesion performance between the film layer and the substrate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-7 As an embodiment of this utility model, the film peel strength testing device for the coated product includes a test bench 1, a control panel 2, and a crossbeam support 3. The top of the test bench 1 is provided with a clamping platform 4 and a support 5. One side of the support 5 is provided with a pressing platform 6 for fixing one side of the film layer and a support base 7. A rotating shaft 8 and a rotating arm 9 are rotatably mounted on the support base 7. The rotating arm 9 has a cavity 14 and a slot 15. The rotating arm 9 is provided with a transmission mechanism and a threaded adjustment mechanism that cooperates with the transmission mechanism. A support rotation mechanism is provided on one side of the support base 7.

[0025] In this embodiment, the test sample is initially placed on the clamping table 4 and fixed. Then, one end of the film layer on the top of the test sample is fixed by the pressing table 6. Then, the other end of the film layer is fixed by the clamp at the bottom of the rotating arm 9. At this time, the rotating arm 9 is driven to rotate 90 degrees. During the rotation, the film layer is pulled. At the same time, the transmission mechanism cooperates with the transmission thread adjustment mechanism to extend outward during the rotation peeling process, which can straighten the film layer and prevent the film layer from curling. The supporting rotation mechanism can guide the rotation of the rotating arm 9.

[0026] As a further embodiment of the present invention, the transmission mechanism includes a screw 16 rotatably mounted on the cavity 14 and a transmission tooth 17 sleeved on the end of the screw 16, the end of the screw 16 extending through to one side of the rotating arm 9.

[0027] In this embodiment, the cavity 14 and the slot 15 on the rotating arm 9 are interconnected, the screw 16 extends to one side of the rotating arm 9, and the transmission tooth 17 is fixedly sleeved on the end of the screw 16.

[0028] As a further embodiment of the present invention, the transmission mechanism further includes a semi-circular toothed disc 18 disposed on the top of the support base 7, the semi-circular toothed disc 18 meshing with the transmission teeth 17.

[0029] In this embodiment, the semi-circular toothed disk 18 is disposed on one side of the rotating shaft 8. When the rotating arm 9 is flipped, the transmission tooth 17 will move in a circular motion toward the semi-circular toothed disk 18, thereby causing the transmission tooth 17 to rotate. At the same time, the transmission tooth 17 will drive the screw 16 to rotate.

[0030] As a further embodiment of this utility model, the threaded adjustment mechanism includes a threaded block 19 threadedly mounted on the screw 16, and the threaded block 19 is slidably mounted on the slot 15.

[0031] In this embodiment, the threaded block 19 is threaded onto the screw 16, and the bottom of the threaded block 19 slides on the slot 15.

[0032] As a further embodiment of this utility model, the thread adjustment mechanism also includes a support mechanical arm 20 disposed at the bottom of the thread block 19 and a mechanical claw 21 disposed on the support mechanical arm 20 for gripping the film layer, the mechanical claw 21 being disposed on one side of the clamping table 4.

[0033] In this embodiment, when the threaded block 19 slides, it will drive the supporting robotic arm 20 and the robotic claw 21 to move, so that the clamp extends outward during the rotation and peeling process, which can straighten the film layer and prevent the film layer from curling. This avoids problems such as uneven stress distribution and additional bending moment caused by curling, thereby improving the accuracy of the peel strength test and making the test results more realistically reflect the true adhesion strength between the film layer and the substrate.

[0034] As a further embodiment of this utility model, the supporting rotation mechanism includes a rotating guide frame 11 disposed on one side of the support 5 and an arc-shaped groove 12 formed on the rotating guide frame 11. The rotating arm 9 is provided with cylinders 10 on both sides, and the cylinders 10 slide on the arc-shaped groove 12.

[0035] In this embodiment, the cylinder 10 on the rotating arm 9 slides on the arc groove 12 on the rotating guide frame 11, which can limit the rotation direction of the rotating arm 9 and provide support during the rotation of the rotating arm 9.

[0036] As a further embodiment of this utility model, the support rotation mechanism includes a motor 13 disposed on one side of the support base 7, and the output shaft of the motor 13 is fixed to the rotation shaft 8.

[0037] In this embodiment, by starting the motor 13, the output shaft of the motor 13 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the rotating arm 9 to perform a 90° rotation peel test, which accurately simulates the stress situation of the film layer in actual application, improves the effectiveness and accuracy of the test results, and helps to correctly evaluate the adhesion performance between the film layer and the substrate.

[0038] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
