Description

Technical Field

[0001] The present invention relates to the technical field of IMD films, and particularly relates to an IMD film with 3D touch and a high-temperature and high-humidity test device therefor. Background Art

[0002] The IMD film is a technology for surface decoration of plastic products. By combining a pre-printed film with an injection molding process, a surface treatment that integrates decoration and functionality is achieved; while the IMD film with 3D touch is to set a specific shape during the injection molding process, so as to achieve a state with 3D touch in terms of touch. The IMD film is widely used in the fields of household appliances, automobiles, mobile phones, electronic products, etc.

[0003] For example, the Chinese patent with the publication number CN220982958U discloses a proton exchange membrane wet-dry cycle durability test device, which includes a box body, a bracket arranged in the box body, a heating pipe, and a fan installed on the top of the box body. The box body is provided with an air outlet, and the box body is equipped with a refrigeration system and a water circulation system. When in use, the test device can simulate the application scenarios of a hydrogen fuel cell, such as high temperature, humidity, dryness, and blowing application scenarios, the switching from a high-temperature scenario to a low-temperature scenario, and the switching from humidity to dryness, to test the physical durability of the proton exchange membrane, which is beneficial for producers to accurately judge the performance of the proton exchange membrane.

[0004] However, there are still some deficiencies in the above test device during actual use:

[0005] 1. First of all, the above-mentioned prior art detects the performance of the film by changing different environments, and when detecting its performance, the sample needs to be taken out to test the tensile strength and transmittance; however, taking out the sample for detection will cause the temperature of the sample to change, and detecting its performance at this time will seriously affect the accuracy of the sample detection result, and the existing device has a poor detection effect on the film.

[0006] 2. In addition, the above-mentioned device states that the film is mainly clamped by the bracket in the box body, and the bracket is composed of a left half fixture and a right half fixture. The left half fixture and the right half fixture are used to clamp and limit the film. When clamping each group of films, the left half fixture and the right half fixture need to be moved, resulting in a relatively cumbersome film clamping method.

[0007] Therefore, under the above-stated viewpoints, there is still room for improvement in the existing test device. Summary of the Invention

Detailed implementation manners

[0047] The following is a further detailed description in conjunction with Figures 1 - 13 This application.

[0048] The embodiments of this application disclose an IMD film with a surface 3D tactile feeling and its high temperature and high humidity test device; this application is mainly applied to the quality inspection process after the production of the IMD film 1. After the IMD film 1 is produced, in order to ensure its stable use performance and ensure that the IMD film 1 meets the standards, it is necessary to detect the produced product to monitor the quality of the produced product.

[0049] Refer to Figure 13As shown in the figure, an IMD film with a surface 3D tactile sensation includes a transfer substrate 10, a transfer structure layer 11, a 3D TopCoat protective layer 12, a decorative layer 13, and a transfer adhesive layer 14, which are arranged in sequence. The IMD film 1 has a surface 3D tactile sensation and high stretchability. The 3D tactile sensation refers to the appearance and structure of the TopCoat structure layer on the surface of the IMD film 1.

[0050] The 3D TopCoat protective layer 12 is close to the transfer structure layer 11, and there is a three-dimensional concave-convex structure that fits with each other on the surfaces where they are close to each other. The transfer structure layer 11 can be peeled off from the 3D TopCoat protective layer 12.

[0051] The material of the transfer substrate 10 is PET, with a thickness of 38-100 μm; the surface of the PET has been chemically treated.

[0052] The transfer structure layer 11 belongs to the photocuring system, and the resins used are silicone-modified photocuring resin, fluorine-modified photocuring resin, long fatty chain photocuring acrylic resin, etc.; the structure on the surface of the metal roller is replicated on the primer surface of the transfer substrate 10 by a metal roller with a structure; the transfer structure layer 11 has a certain forming stretchability.

[0053] The material of the 3D TopCoat protective layer 12 is selected from at least one of the following three systems: photocuring system, thermosetting system, and thermoplastic coating system.

[0062] (5) The finished product is aged, wound up and slit to obtain the product.

[0063] The material of the transfer substrate 10 is PET with a thickness of 38 - 100 μm. An acrylic primer is coated on the transfer substrate 10 near the transfer structure layer 11, and the transfer structure layer 11 is disposed on the acrylic primer. The material of the transfer structure layer 11 is a photo-curable silicone-modified acrylic resin. The material of the transfer structure layer 11 is coated on the transfer substrate 10 by a metal roller with a predetermined three-dimensional structure to quickly form the transfer structure layer 11, and then the raw material of the liquid 3D TopCoat protective layer 12 is coated on the transfer structure layer 11, and a three-dimensional structure with a surface touch is formed when irradiated with ultraviolet light (or) heated.

[0064] The 3D TopCoat protective layer 12 is selected from at least one of the following three types of systems: photo-curable system, thermo-curable system, thermoplastic coating system; the transfer structure layer 11 is a photo-curable resin system. The 3D TopCoat protective layer 12 is selected from one of UV curing, thermo-curing, thermoplastic coating or a mixed system of any two or three of them, and the main components are one or several of thermoplastic acrylate, hydroxy acrylate, polyester resin, polyurethane acrylate, epoxy acrylate, polyester acrylate, etc.; the structure of the transfer structure layer 11 can be easily replicated and peeled off.

[0073] Table 1 Performance test results of the IMD films of Examples 1 - 4

[0074]

[0075]

[0076] It can be seen from the performance test results of the IMD film 1 in each example that the IMD film 1 has strong structural stability, and the 3D TopCoat protective layer 12 and the electroplated decorative layer are not prone to tensile cracks, and it has excellent weather resistance, heat resistance, solvent resistance, scratch resistance, and excellent appearance effect.

[0077] Furthermore, the IMD film 1 with 3D touch in this application usually needs to be subjected to performance detection after production, but the existing detection devices are poor and have the following problems:

[0078] First of all, the above-mentioned prior art detects the performance of the film by changing different environments, and when detecting its performance, the sample needs to be taken out to test the tensile strength and transmittance; however, taking out the sample for detection will cause the temperature of the sample to change, and detecting its performance at this time will seriously affect the accuracy of the sample detection result, and the existing device has a poor detection effect on the film.

[0079] In addition, the above-mentioned device states that the film is mainly clamped by the bracket in the box, and the bracket is composed of a left half fixture and a right half fixture. The left half fixture and the right half fixture are used to clamp and limit the film. When clamping each group of films, the left half fixture and the right half fixture need to be moved, resulting in a more cumbersome film clamping method.

[0080] Therefore, to solve the above problems, this application proposes a high-temperature and high-humidity detection device for an IMD film with 3D touch.

[0081] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the high-temperature and high-humidity detection device includes a stationary detection box 2; several feeding grooves 20 are formed on one side of the detection box 2, and a plug-in frame 21 is installed in the feeding grooves 20 by means of sliding insertion. A telescopic tension spring 22 is installed between one side of the plug-in frame 21 and the detection box 2; a linkage clamping component 3 for clamping the IMD film 1 with 3D touch is provided on the plug-in frame 21.

[0082] In the initial state, the plug-in frame 21 is inserted into the feeding groove 20 of the detection box 2 and is always located inside the detection box 2 under the pulling of the telescopic tension spring 22.

[0083] A detection component 4 for scraping the surface of the transfer substrate 10 of the IMD film 1 to detect the retention and fullness of the surface texture of the transfer substrate 10 is also provided in the detection box 2.

[0084] During specific implementation, when it is necessary to detect the IMD film 1, first randomly select several groups of IMD films 1 from the produced IMD films 1 as samples, and then clean their surfaces.

[0085] Then, the plug-in frame 21 is extended from the inside of the detection box 2, and the sample is placed on the plug-in frame 21. Subsequently, the plug-in frame 21 is reinserted into the inside of the detection box 2. During this process, the linkage clamping component 3 on the plug-in frame 21 automatically limits and clamps the sample placed in the plug-in frame 21. After the sample is clamped, the plug-in frame 21 can just be completely inserted into the detection box 2. Finally, the detection component 4 performs detection on it.

[0086] Refer to Figure 5 As shown, it is a schematic structural diagram for controlling the telescopic movement of the plug-in frame 21 in this application; specifically, an expansion and contraction member 8 for automatically controlling the telescopic movement of the plug-in frame 21 is further provided outside the detection box 2. The expansion and contraction member 8 includes an expansion and contraction swing arm 80 rotatably connected to the outer wall of the detection box 2. A control gear 81 is installed at the hinge point of the expansion and contraction swing arm 80, and the end of the expansion and contraction swing arm 80 far from the control gear 81 is a hand-held end.

[0087] A limit post 82 is slidably inserted through one side of the expansion and contraction swing arm 80 close to the hand-held end. One side of the limit post 82 extends towards the outer wall of the detection box 2 and abuts against the outer wall of the detection box 2. The limit of the expansion and contraction swing arm 80 is achieved by controlling the engagement and disengagement between the limit post 82 and the detection box 2.

[0088] During specific implementation, hold the handheld end of the handheld telescopic swing arm 80 and pull the telescopic swing arm 80 to rotate clockwise. While the telescopic swing arm 80 rotates clockwise, it drives the engaged control gear 81 to rotate. Then, the control gear 81 controls the linkage gear ring 213 to rotate. During the rotation of the linkage gear ring 213, it drives the linkage gear 212 to rotate. When the linkage gear 212 rotates, the linkage gear 212 controls the control wheel 211 on one side to rotate. When the control wheel 211 rotates, it drives the control belt 210 to rotate clockwise. Then, the control belt 210 controls the plug-in frame 21 connected to its upper end to move away from the detection box 2.

[0089] Until the plug-in frame 21 extends outwards, at this time, the sample can be placed on the plug-in frame 21.

[0090] Look again Figure 4 and Figure 5 As shown in the figure, specifically, two groups of control belts 210 are symmetrically arranged along the length direction of the plug-in frame 21. Control wheels 211 are installed on the two groups of control belts 210. The control wheels 211 are rotatably arranged on the inner wall of the detection box 2. A linkage gear 212 is installed on one side of the control wheel 211. A linkage gear ring 213 that rotates on the outer wall of the detection box 2 is also engaged with the linkage gear 212. Both the linkage gear 212 and the linkage gear ring 213 are rotatably arranged on the outer wall of the detection box 2.

[0091] One side of the linkage gear ring 213 meshes with the control gear 81 on the telescopic swing arm 80 and does not interfere with each other.

[0092] It should be noted that the tail of the plug-in frame 21 is connected to the control belt 210. When the control belt 210 rotates clockwise, the plug-in frame 21 extends out along the loading chute 20 of the detection box 2. At this time, the sample can be installed.

[0093] When the control belt 210 rotates counterclockwise, the plug-in frame 21 moves towards the inside of the detection box 2 along the loading chute 20.

[0094] Similarly, when the sample to be detected is placed in the plug-in frame 21, push the telescopic swing arm 80 in the reverse direction. When the telescopic swing arm 80 rotates counterclockwise, it drives the plug-in frame 21 to contract into the detection box 2; at the same time, when the plug-in frame 21 contracts, it limits and clamps the sample placed on its upper end.

[0095] Refer to Figure 6 、 Figure 7 and Figure 8As shown, it is a schematic structural diagram of the present application for controlling the telescopic swing arm 80 to clamp the sample through the linkage clamping component 3 at the same time; specifically, the linkage clamping component 3 includes support pieces 30 rotatably connected at the four corners at the bottom of the insertion frame 21, and moving gears 31 are installed on the four groups of support pieces 30. A horizontal rack 32 on the same horizontal line as the four moving gears 31 is installed on the inner wall of the detection box 2.

[0096] Clamping gears 33 are also symmetrically and rotatably installed on the insertion frame 21 along the height direction. A coaxial rod 36 is installed between the two symmetrically distributed clamping gears 33 on the same side of the insertion frame 21. Clamping rods 34 are equidistantly installed on the coaxial rod 36. The symmetrically distributed clamping rods 34 respectively abut against the transfer substrate 10 and the transfer adhesive layer 14. A clamping rack 35 corresponding to the four clamping gears 33 is installed inside the detection box 2.

[0097] In the initial state, the insertion frame 21 is located inside the detection box 2. At the same time, the four groups of support pieces 30 at the bottom of the insertion frame 21 are retracted into the insertion frame 21. When the telescopic swing arm 80 is rotated clockwise to control the insertion frame 21 to move out of the detection box 2, the moving gears 31 on the four support pieces 30 will contact the horizontal rack 32 inside the detection box 2. Subsequently, the moving gears 31 are forced to rotate. When the moving gears 31 rotate, the support pieces 30 at their upper ends will rotate towards the center position of the insertion frame 21 until the four groups of support pieces 30 at the bottom of the insertion frame 21 are exposed and are distributed in an "X" shape structure at the bottom of the insertion frame 21.

[0098] When the support pieces 30 are unfolded and located at the bottom of the insertion frame 21, the sample to be detected can be placed into the insertion frame 21, and it is sufficient to place the sample to be detected on the support pieces 30 of the insertion frame 21.

[0099] When the telescopic swing arm 80 is rotated counterclockwise, the insertion frame 21 moves into the detection box 2; during this process, the moving gears 31 on the insertion frame 21 mesh with the horizontal rack 32 inside the detection box 2. After the two come into contact, the moving gears 31 on the insertion frame 21 are rotated passively, and the moving gears 31 will drive the clamping rods 34 to rotate until the clamping rods 34 abut against the sample to be detected, and the sample to be detected is clamped and fixed through multiple groups of clamping rods 34, ensuring that the IMD film 1 of the sample to be detected is restricted in the insertion frame 21; and the IMD film 1 of the sample to be detected is in a flattened state.

[0100] It should be noted that when the insertion frame 21 moves away from the detection box 2, the support pieces 30 are all unfolded, facilitating the placement of the IMD film 1 of the sample to be detected; when the insertion frame 21 moves closer to the detection box 2, the support pieces 30 gradually contract, facilitating the clamping of the IMD film 1 of the sample to be detected by the clamping rods 34.

[0101] After the 3D tactile IMD film 1 is clamped and laid flat inside the detection box 2, it is detected by the detection component 4.

[0102] Referring to Figure 9 and Figure 10 As shown, the detection component 4 includes a detection cylinder 60 for detecting the 3D convex structure on the surface of the 3D TopCoat protective layer 12. An optical detector 61 is provided inside the detection cylinder 60. A lifting bracket 62 is installed inside the detection box 2. A number of strip-shaped grooves 63 are equidistantly arranged on the lifting bracket 62. The detection cylinder 60 is slidably arranged in the strip-shaped grooves 63 of the lifting bracket 62. Flexible detection components 64 are symmetrically installed on both sides of the optical detector 61 through connecting frames.

[0103] A high-temperature and high-humidity generator 5 is also provided on the detection box 2.

[0104] After the IMD film 1 to be detected is clamped, the detection cylinder 60 moves downward until the optical detector 61 inside the detection cylinder 60 can detect the concave and convex structure on the surface of the IMD film 1 to ensure the radian of the concave and convex structure on the surface of the IMD film 1.

[0105] The high-temperature and high-humidity generator 5 is started. The high-temperature and high-humidity generator 5 performs heating and humidifying treatment on the closed detection box 2, making the detection box 2 constant at a specified temperature and humidity state; after it is constant, the detection cylinder 60 moves downward again until the optical detector 61 inside the detection cylinder 60 can detect the concave and convex structure on the surface of the IMD film 1 to ensure the radian of the concave and convex structure on the surface of the IMD film 1.

[0106] In the initial state, the concave and convex radian and deformation condition on the surface of the IMD film 1 are detected by the optical detector 61. Subsequently, in a high-temperature and high-humidity environment, the concave and convex radian and deformation condition on the surface of the IMD film 1 are detected again by the optical detector 61; by comparing the two detections, the performance of the IMD film 1 under high temperature and high humidity is determined.

[0107] If the data detected by the optical detector 61 in the second detection is smaller than that in the first detection, it indicates that the IMD film 1 has collapsed under high temperature and high humidity, and the performance of the IMD film 1 is poor; if the data detected by the optical detector 61 in the second detection is larger than that in the first detection, it indicates that there are delamination bubbles in the IMD film 1 under high temperature and high humidity, and the performance of the IMD film 1 is also poor; if the data detected by the optical detector 61 in the second detection is the same as that in the first detection, it indicates that the performance of the IMD film 1 always remains in the best state under high temperature and high humidity.

[0108] Furthermore, in order to accurately detect the performance of the IMD film 1 under high temperature and high humidity and improve the accuracy of the performance detection of the IMD film 1, the present application can also adjust the positions of a plurality of detection cylinders 60, so that the detection cylinders 60 can move along the strip-shaped grooves 63 of the lifting bracket 62, enabling the detection cylinders 60 to perform performance detection on multiple different positions of the IMD film 1. This can not only avoid accidental situations, but also form data comparisons through the performance detection of multiple different positions of the IMD film 1, thereby improving the accuracy of the detection results.

[0109] After the optical detector 61 detects the fullness of the IMD film 1, it is also necessary to detect the toughness strength of the IMD film 1 through the flexible detection component 64.

[0110] Refer to Figure 10 、 Figure 11 and Figure 12 As shown in

[0111] Specifically, the flexible detection component 64 includes an electric push rod 640 provided on a connecting frame mounted on the top of the optical detector 61. The output end of the electric push rod 640 extends downward and is connected to a pressing rod 641. The bottom of the pressing rod 641 is a threaded structure, and a plurality of pressing detection heads 642 with different shapes are installed at the bottom of the pressing rod 641 by screwing.

[0112] During specific implementation, the electric push rod 640 is started, and the output end of the electric push rod 640 drives the pressing rod 641 and the pressing detection heads 642 at the bottom of the pressing rod 641 to move synchronously. At this time, the pressing detection heads 642 will contact the surface of the IMD film 1 and press the IMD film 1.

[0113] It should be noted that the downward extension stroke of the output end of the electric push rod 640 is fixed. After the output end of the electric push rod 640 extends downward, the pressing detection heads 642 will press the IMD film 1, and the applied downward pressure is the same.

[0114] Refer to Figure 12As shown, a lifting frame 643 is provided in the middle of the pressing rod 641. The lifting frame 643 divides the pressing rod 641 into two sections. One section is connected to the lifting frame 643, and the other section slides through the lifting frame 643. A horizontal plate 644 is installed on the pressing rod 641 that slides on the lifting frame 643. A lifting adjustment rod 645 is rotatably provided on the horizontal plate 644. One end of the lifting adjustment rod 645 away from the horizontal plate 644 rotatably passes through the top of the detection cylinder 60 and extends to the outside of the detection cylinder 60.

[0115] It should be noted that the lifting adjustment rod 645 moves up and down synchronously with the movable pressing rod 641. Secondly, a window is provided on the detection box 2 for the lifting adjustment rod 645 to adjust.

[0116] In the initial state, the two sections of the pressing rod 641 in this application are abutted against each other. At this time, the combined length of the two pressing rods 641 is the shortest. The output end of the electric push rod 640 drives the pressing rod 641 and the pressing detection head 642 to slowly approach the IMD film 1. At this time, the pressure applied to the IMD film 1 reaches the minimum value.

[0117] Furthermore, it should be noted that the pressing detection head 642 is installed on the pressing rod 641 by means of threaded connection. Therefore, different-shaped pressing detection heads 642 can be replaced, and the performance of the IMD film 1 can be detected by multiple different-shaped pressing detection heads 642.

[0118] During operation: In the first step, when it is necessary to detect the IMD film 1, several IMD films 1 are randomly selected from the produced IMD films 1 as samples, and then their surfaces are cleaned.

[0119] In the second step: Hold the hand-held end of the telescopic swing arm 80 and pull the telescopic swing arm 80 to rotate clockwise. The telescopic swing arm 80 drives the control belt 210 to rotate clockwise. Then the control belt 210 controls the plug-in frame 21 connected to its upper end to move away from the detection box 2 until the plug-in frame 21 extends outwards.

[0120] In the third step: After the plug-in frame 21 extends out, place the IMD film 1 into the plug-in frame 21, and push the telescopic swing arm 80 in the reverse direction. When the telescopic swing arm 80 rotates counterclockwise, it drives the plug-in frame 21 to contract into the detection box 2; at the same time, when the plug-in frame 21 contracts, it limits and clamps the sample placed on its upper end.

[0121] In the fourth step: When the IMD film 1 to be detected is clamped, the detection cylinder 60 moves downward until the optical detector 61 in the detection cylinder 60 can detect the concave and convex structures and deformation conditions on the surface of the IMD film 1 to ensure the fullness of the surface of the IMD film 1 and whether serious deformation has occurred.

[0122] Step 5: Next, the electric push rod 640 is activated, and the electric push rod 640 controls the downward pressure detection heads 642 of different shapes to perform puncture resistance performance detection on the IMD film 1 under the same pressure.

[0123] Step 6: When different pressures need to be applied to the IMD film 1, rotate the lifting adjustment rod 645. The lifting adjustment rod 645 controls the downward pressure rod 641 near the downward pressure detection head 642 in the lifting frame 643 to move downward, so that the length between the two downward pressure rods 641 becomes longer. At this time, when the IMD film 1 is pressed downward again, due to the change in the length of the downward pressure rod 641, the pressure applied by the downward pressure detection head 642 at the bottom of the downward pressure rod 641 to the IMD film 1 also becomes larger; at this time, the puncture resistance performance detection of the IMD film 1 with different pressure intensities can be carried out.

[0124] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
