Description

Technical Field

[0001] The present invention relates to the technical field of metallized film detection equipment, in particular to a device for detecting the heat resistance of a metallized film. Background Art

[0002] Metallized film is a composite material created by depositing a metal layer on a plastic film through a specialized process. Combining the flexibility of polymer materials with the conductive / reflective properties of metals, it is widely used in electronics, power generation, packaging, optics, and other fields. Through innovative materials and processes, metallized film combines lightweight, functional, and cost-effective materials, making it a key material for the future of flexible electronics, new energy, and high-end packaging.

[0003] Heat resistance testing of metallized films is a key test for evaluating their performance stability in high-temperature environments. It involves a comprehensive examination of the substrate, metal layer, and the bonding strength between the two. Heat resistance testing of metallized films requires examining the surface properties of the film at high temperatures, such as cracking and localized warping of the metal layer. Existing testing devices for metallized films typically place the sample on a fixed platform and use an observation window to observe the film, or simply remove the sample for visual inspection. Heat resistance testing may require observing the sample at different heating time intervals. Repeated placement and removal of the sample can cause repeated cooling and heating, affecting test results. In actual use, due to the varying locations of cracks and localized warping in the sample's metal layer, testers must adjust their posture, viewing height, and viewing angle to observe the sample, impacting both test effectiveness and efficiency. Furthermore, when the sample is heated for a short time, the degree of warping is minimal, making the separation between the metal layer and the substrate less apparent. This can easily lead to oversight by testers observing from the outside. To address this issue, we propose a device for testing the heat resistance of metallized films. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] A device for detecting heat resistance of metallized film, such as Figures 1-8 As shown, it includes a shell 1; a surface testing mechanism 2 is provided in the middle of the shell 1 for performing high-temperature aging and bonding strength tests on the metallized film.

[0036] Specifically, the surface testing mechanism 2 includes a sealing cover 21. There are two sealing covers 21, and the two sealing covers 21 are symmetrically arranged in the middle of the shell 1. A supporting platform 22 is fixedly connected to the inside of the sealing cover 21. The sealing cover 21 is a hemispherical structure. The sealing cover 21 and the supporting platform 22 are both made of transparent materials. The hemispherical sealing cover 21 can seal the test sample. At the same time, the transparent sealing cover 21 can facilitate the inspection personnel to observe the internal sample during the high-temperature test. At the same time, the hemispherical sealing cover 21 made of transparent material can form a structure similar to a convex lens, thereby magnifying the sample and improving the observation effect of the test results. The supporting platform 22 can facilitate the placement of the sample.

[0037] In addition, the front of the housing 1 is provided with a door 23, which is provided with an observation window 24. The position of the observation window 24 corresponds to that of the sealing cover 21. The height of the observation window 24, the sealing cover 21, and the tester are all aligned, allowing the tester to directly observe the sealing cover 21 through the observation window 24, eliminating the need to bend or squat to adjust their posture. A heating device 25 is fixedly connected to the interior of the housing 1, which can continuously heat the interior of the housing 1 to perform heat resistance testing on the metallized film.

[0038] Example 2

[0039] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 As shown, on the basis of embodiment 1, an angle adjustment mechanism 3 is provided on the outside of the surface testing mechanism 2 for adjusting the angle of the surface testing mechanism 2 .

[0040] In this embodiment, an angle adjustment mechanism 3 is connected to the outside of the sealing cover 21, and the angle adjustment mechanism 3 includes an adjusting rod 31, which is fixedly connected to the middle of the outside of the sealing cover 21, and a sleeve rod 32 is sleeved on the outside of the adjusting rod 31. A support frame 33 is fixedly connected to the side of the sleeve rod 32. The support frame 33 can support and position the sealing cover 21 through the sleeve rod 32 and the adjusting rod 31. At the same time, the adjusting rod 31 is rotatably connected to the inside of the sleeve rod 32. The rotation of the support rod can drive the sealing cover 21 to rotate, thereby realizing the angle adjustment of the sample so that the sample can be visually inspected at different angles.

[0041] On this basis, an adjustment groove 34 is opened on the side of the sleeve rod 32, and a transmission gear 35 that meshes with each other is fixedly connected to the support frame 33 and the outside of the adjustment rod 31. The position of the transmission gear 35 and the adjustment groove 34 correspond to each other. The structure of the adjustment groove 34 can conveniently accommodate the transmission gear 35. At the same time, the transmission gear 35 can drive the adjustment rod 31, so that the adjustment rod 31 can drive the sealing cover 21 to rotate circumferentially.

[0042] Furthermore, a drive handle 36 is rotatably connected to the inner side of the support frame 33. The drive handle 36 is disposed on the outer side of the housing 1. The drive handle 36 can drive the support frame 33 to rotate. A circular baffle is fixedly connected to the middle of the support frame 33. The side of the housing 1 has a through hole corresponding to the baffle structure. The baffle can rotate inside the through hole and block the through hole. The end of the drive handle 36 and the upper end of the transmission gear 35 are both fixedly connected to a transmission shaft 37. A transmission belt 38 is sleeved on the outer side of the transmission shaft 37. The rotation of the drive handle 36 can drive the transmission belt 38 and the transmission gear 35 to rotate synchronously, thereby controlling the rotation of the sealing cover 21.

[0043] It is worth noting that there are two driving handles 36, and the two driving handles 36 are connected end to end. A transmission rod 39 is slidably connected inside the driving handle 36, and the two ends of the transmission rod 39 are respectively passed through the ends of the two driving handles 36. The two driving handles 36 structure can drive the two sealing covers 21 separately. At the same time, the transmission rod 39 structure can facilitate the sliding adjustment of the two driving handles 36, and facilitate the two driving handles 36 to move away from each other, so that the driving handles 36 can keep driving the sealing covers 21 after the two sealing covers 21 are opened and closed.

[0044] Example 3

[0045] like Figure 1-Figure 5 as well as Figure 7 As shown, on the basis of Example 2, a strength testing mechanism 4 is provided above the appearance testing mechanism 2 for performing a strength test on the metallized film under a high temperature state.

[0046] In this embodiment, the strength testing mechanism 4 includes a support base 41, which is slidably connected to the interior of the housing 1. A drive groove 44 corresponding to the adjustment rod 31 is provided on the inner side of the support base 41. The support base 41 can support the appearance testing mechanism 2. The inner side of the support base 41 is an arc-shaped structure, and the adjustment rod 31 can rotate within the drive groove 44. At the same time, the arc-shaped support base 41 can limit the rotation of the adjustment rod 31. A detection rod 42 is fixedly connected to the side of the support base 41, and a tension sensor 43 is fixedly connected to the end of the detection rod 42. The detection rod 42 has an L-shaped structure, and the ends of the two detection rods 42 are arranged facing each other.

[0047] On this basis, a clamping base 45 is fixedly connected to the tension sensor 43, and a clamping block 46 is connected to the clamping base 45. The clamping block 46 structure can clamp the strength test sample and, in conjunction with the tension sensor 43, can test the tensile strength of the metallized film under high temperature conditions. A two-way cylinder 47 is fixedly connected to the back of the housing 1. The end of the output shaft of the two-way cylinder 47 is fixedly connected to the support base 41. The two-way cylinder 47 can drive both clamping bases 45 simultaneously.

[0048] To use the heat-resistant performance testing device for metallized films of the present invention, the chamber door 23 is first opened, and two samples are simultaneously removed for use. One sample is placed on the support platform 22, while the other is clamped and secured by the upper clamping block 46. A bidirectional cylinder 47 is then activated, driving the two support bases 41 toward each other. The sealing cover 21 and the support platform 22 then move toward each other and seal. The sample on the clamping block 46 then moves with the support base 41, and the bottom of the sample contacts the lower clamping block 46, which then clamps and secures the bottom of the sample. The interior of the housing 1 is then continuously heated by the heating device 25. Once the interior of the housing 1 reaches a set temperature, the bidirectional cylinder 47 is activated, driving the two support bases 41 away from each other. As the support bases 41 move away from each other, they pull the tension sensor 43 with the detection rod 42. Since the clamping blocks 46, to which the tension sensor 43 is fixed, clamp the sample at both ends, the tensile force applied to the tension sensor 43 is the same as the tensile force applied to the sample.

[0049] After completing the high-temperature strength test, the bidirectional cylinder 47 then drives the support base 41 closer to each other and closes the sealing cover 21. The sample inside the sealing cover 21 is then tested for high-temperature aging and high-temperature bonding strength. During the test, the tester can adjust the pitch angle or horizontal angle of the sealing cover 21 through the angle adjustment mechanism 3, so as to observe the sample at different angles. When adjusting the angle, the tester can rotate the support frame 33 through the drive handle 36, so that the adjustment rod 31 slides inside the drive groove 44, and adjusts the pitch angle of the sealing cover 21. At the same time, rotating the drive handle 36 in the circumferential direction can drive the transmission gear 35 to rotate through the transmission shaft 37 and the transmission belt 38, and then adjust the horizontal angle of the sealing cover 21 through the adjustment rod 31. The sealing cover 21 can be adjusted to any angle using the angle adjustment mechanism 3, which makes it convenient for the tester to observe the sample from different angles and improve the observation efficiency of the sample high-temperature aging and high-temperature bonding strength test.
