Abstract
Description
Technical Field
[0001] This invention relates to the field of new material release film testing technology, specifically a new type of weather resistance testing equipment for release film production. Background Technology
[0002] As a product of the new materials industry, the new release film is a functional film developed through substrate innovation and surface treatment technology upgrades. Its core characteristic is the ability to precisely control the peel force with adhesive materials, while meeting special requirements such as high temperature resistance and light transmittance. During the production and processing process, in order to meet the usage requirements in different scenarios, weather resistance testing is required for the release film. Generally, it is simulated natural environment or accelerated aging to evaluate its performance stability under the influence of long-term climatic factors. This mainly includes high temperature and corrosion testing for the release film. This type of testing is a key quality control link to ensure the stable performance of the release film in outdoor application scenarios such as photovoltaics and electronics.
[0003] The utility model disclosed in CN213022797U is a high-temperature aging test chamber for PET non-silicone release film. When the test chamber is used for a long time and the gap between the door and the body increases, the collar bolt on the side of the sliding sleeve can reduce the gap between the door and the body, making the door and body more airtight and more conducive to the accurate testing of the release film. At the same time, the door handle is a split and detachable structure, and there is no opening in the door, which is more conducive to the heat preservation and sealing of the door.
[0004] The utility model with announcement number CN219758035U discloses a release film aging resistance testing device. A wedge block is fixedly connected to one side of the U-shaped frame. This not only ensures that the door and the box body are in close contact through the second tension spring and the U-shaped frame, improving the sealing effect of the device, but also prevents the U-shaped frame from moving forward through the sliding plate, wedge block and rack, improving the fixing effect of the device. Furthermore, the door can be fixed through the locking mechanism, improving the use effect of the device.
[0005] However, the weather resistance testing device for release films of new materials disclosed above still has the following problems in actual use: the testing device is used in conjunction with the protective door on the front to improve the heat insulation and sealing effect of the test, but the testing device does not disclose the testing method for the weather resistance of the release film. The fully enclosed environment cannot effectively simulate the real scenario of daily use. In the weather resistance test, the tension of the release film will also affect the test data. When the release film is loose, it is more likely to curl when heated, which affects the effect of uniform heating. Furthermore, it cannot simulate the corrosion damage during daily use, which affects the testing efficiency and test data of the release film.
[0006] Therefore, we propose a new type of weather resistance testing equipment for release film production to solve the problems mentioned above. Summary of the Invention
[0007] The purpose of this invention is to provide a novel weather resistance testing device for release film production. This addresses the shortcomings of existing testing devices that rely on a protective enclosure door to improve insulation and sealing. However, these devices do not disclose specific testing methods for the weather resistance of release films. The fully enclosed environment cannot effectively simulate real-world usage scenarios. Furthermore, the tension of the release film also affects the test data; a loose release film is more prone to curling when heated, affecting uniform heating and failing to simulate corrosion damage during daily use. These factors all contribute to the inefficiency and inaccurate test data for release films.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel weather resistance testing device for release film production, comprising a testing platform and an operating area disposed on the front of the testing platform, and a protective enclosure disposed above the top surface of the testing platform;
[0009] It also includes: a positioning mechanism is provided on the top surface of the detection platform, and the positioning mechanism includes a supporting base plate, and the left and right sides behind the top surface of the supporting base plate are slidably connected to the lower end of the positioning slide rod.
[0010] The upper ends of the symmetrically arranged positioning slide rods are all fixedly installed with positioning arc plates, which are used to position the release film by descending.
[0011] The testing platform is equipped with a testing mechanism, which includes a thermal aging platform. The thermal aging platform performs high-temperature aging testing on the release film pushed by the positioning mechanism.
[0012] Preferably, the positioning mechanism includes a positioning slider, which is fixedly installed on the left and right sides of the bottom surface of the supporting base plate. The positioning sliders are symmetrically arranged and slidably connected to guide rails inside, which are fixedly installed below the bottom surface of the detection platform.
[0013] Preferably, the positioning mechanism includes a guide screw, which is rotatably mounted at the center of the bottom surface of the detection platform via a bearing, and the front end of the guide screw is fixedly connected to the end of the output shaft of the servo motor, and the guide screw is threaded through and connected to the protrusion on the bottom surface of the bearing base plate.
[0014] Preferably, the positioning mechanism includes a positioning base plate, which is fixedly installed in the lower middle part of the detection platform. The top surface of the positioning base plate is inclined with the front higher and the back lower, and the inclined surface of the positioning base plate is in contact with the bottom end of the positioning slide rod.
[0015] Preferably, the testing mechanism includes a lifting screw, which is rotatably mounted at the rear center of the protective housing via a bearing. The bottom end of the lifting screw is connected to the rear end of the guide screw on the bottom surface of the testing platform via a bevel gear assembly. The outer wall of the lifting screw is threadedly connected to the rear end of the heat-curing platform, causing the heat-curing platform to descend when the positioning mechanism moves, thereby performing a heating aging test on the release film after positioning.
[0016] Preferably, the detection mechanism includes lifting slide bars, which are fixedly installed on the left and right sides inside the front of the protective box. The symmetrically arranged lifting slide bars slide through the outer end of the closed partition door, so that the closed partition door moves up and down against the inner wall of the protective box to achieve heat insulation and sealing protection.
[0017] Preferably, the testing mechanism includes a material retrieval window, which is located on the lower front of the protective box. The material retrieval window is opened and closed by lifting and lowering a closed partition door. The upper end of the closed partition door is fixedly connected to the front end of the heat treatment platform, and the lifting and lowering of the heat treatment platform drives the closed partition door to operate synchronously.
[0018] Preferably, the detection mechanism includes an acid storage tank, which is fixedly installed on the left and right sides inside the positioning base plate. A spray sleeve is fixedly installed in the middle of the positioning base plate, and the rear end of the spray sleeve is connected to the acid storage tank through a one-way infusion pipe. At the same time, a pusher rod is elastically slidably provided inside the spray sleeve.
[0019] Preferably, the front end of the push rod included in the testing mechanism is fixedly connected to the protrusion on the bottom surface of the support base plate. When the push rod moves, it squeezes the corrosive acid inside the spray sleeve. The rear end of the spray sleeve is connected to the spray assembly inside the support base plate. The corrosive acid is sprayed onto the release film covering the top surface of the support base plate through the spray assembly, thereby simulating the weather resistance of different usage scenarios.
[0020] Preferably, the detection mechanism includes a one-way return pipe, which connects the supporting base plate and the acid storage tank, thereby recovering the acid after the simulated corrosion spray into the inside of the acid storage tank for recycling.
[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This novel weather resistance testing equipment for release film production uses a positioning mechanism above the testing platform to position the release film. During the testing process, the heating platform and spray components simulate the high temperature and corrosion effects of daily use, and the testing consumables can be recycled to improve the testing effect. The specific details are as follows:
[0022] 1. The support base plate on the front of the testing platform is in the initial position. The release film to be tested is placed and supported by the support base plate. The servo motor drives the guide screw to rotate, which moves the threaded support base plate and the release film into the interior of the protective box.
[0023] Furthermore, the positioning slide rod and positioning arc plate, which are slidably installed inside the supporting base plate, are used to position the release film. The supporting base plate drives it to move, and the bottom end of the positioning slide rod moves in contact with the positioning base plate. Through the front-high and rear-bottom structure of the top surface of the positioning base plate, the positioning slide rod is driven to slide downward, thereby driving the positioning arc plate to press against the top surface of the release film, ensuring the tension during weather resistance testing.
[0024] 2. The guide screw inside the testing platform rotates, which is driven by the bevel gear group at the rear end engaging with the lifting screw to rotate, so as to drive the threaded heating platform and the closed partition door fixedly connected to the front end to slide downward. After the supporting base plate moves into the protective box, the material opening is closed through the closed partition door, so that the release film can be tested for weather resistance inside the protective box.
[0025] The rotation of the lifting screw drives the heating platform to slide downwards, causing the heating platform to approach the release film positioned above the support base plate. The heating platform heats and bakes the release film to achieve simulated high-temperature weather resistance testing.
[0026] 3. The moving support base plate drives the pusher rod to slide backward, and the pusher rod squeezes the acid inside the spray sleeve, so that the acid is delivered to the spray assembly connected inside the support base plate. Multiple spray assemblies spray the release film above the support base plate to simulate the corrosion effect in daily use environment.
[0027] Furthermore, after the test is completed, the support plate moves the release film forward to reset, pushing the plug rod away from the spray sleeve to create a negative pressure inside. Acid is then drawn from the acid storage tank through the one-way infusion pipe, and the acid stored inside the support plate after spraying is drawn back into the acid storage tank for recycling through the one-way return pipe, reducing consumables and improving the test effect.

Detailed Implementation
[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Please see Figures 1-10 The present invention provides the following technical solution:
[0041] Example 1: To address the existing problems in weather resistance testing of release films, this example discloses the following technical solution: a novel weather resistance testing device for release film production, comprising a testing platform 1 and an operating area 2 located on the front of the testing platform 1, with a protective housing 3 located above the top surface of the testing platform 1; a positioning mechanism is provided on the top surface of the testing platform 1, and the positioning mechanism includes a supporting base plate 4, with the left and right sides of the rear of the top surface of the supporting base plate 4 slidably connected to the lower end of a positioning slide rod 5; the positioning mechanism includes a positioning slider 9, which is fixedly installed on the left and right sides of the bottom surface of the supporting base plate 4, and a guide rail 10 is slidably connected inside the symmetrically arranged positioning slider 9, and the guide rail 10 is fixedly installed below the bottom surface of the testing platform 1.
[0042] The positioning slide rods 5 are symmetrically arranged, and each of them is fixedly mounted with a positioning arc plate 6. The positioning arc plate 6 is used to position the release film by descending. The positioning mechanism includes a guide screw 11, which is rotatably set at the center of the bottom surface of the detection platform 1 through a bearing. The front end of the guide screw 11 is fixedly connected to the end of the output shaft of the servo motor 12, and the guide screw 11 is threaded through and connected to the protrusion on the bottom surface of the support base plate 4. The positioning mechanism includes a positioning base plate 13, which is fixedly installed in the lower middle part of the detection platform 1. The top surface of the positioning base plate 13 is inclined with the front higher and the back lower, and the inclined surface of the positioning base plate 13 is in contact with the bottom end of the positioning slide rod 5.
[0043] like Figures 7-9 As shown, when performing weather resistance testing on the release film, the support base plate 4 on the testing platform 1 is in the initial forward position. Then, the release film is placed on top of the support base plate 4, covering the internal cavity of the support base plate 4. Then, the servo motor 12, which is fixedly installed on the bottom surface of the testing platform 1, drives the fixedly connected guide screw 11 to rotate. The support base plate 4, which is threadedly connected to the guide screw 11, is limited by the testing platform 1, so as to move the support base plate 4 and the release film above it into the protective box 3. The positioning slider 9 below it is slidably connected to the guide rail 10, which improves the stability during the movement and prevents the placed release film from being misaligned and slipping due to the movement.
[0044] Furthermore, when the supporting base plate 4 above the testing platform 1 slides backward, it drives the internally sliding positioning slide rod 5 and positioning arc plate 6 to move synchronously. In the initial state, the bottom end of the positioning slide rod 5 is attached to the highest point of the inclined surface of the positioning base plate 13, causing it to move the positioning arc plate 6 away from the placed release film. As it moves, the inclined surface of the positioning base plate 13 gradually decreases, causing the attached positioning slide rod 5 and positioning arc plate 6 to descend synchronously. Then, the positioning arc plates 6 on the left and right sides press against the bottom left and right sides of the release film above the supporting base plate 4, ensuring the stability of the release film during weather resistance testing, and avoiding excessive shading of the release film, which would affect the weather resistance test.
[0045] Example 2: To address the existing problems in the weather resistance testing of release films, this example discloses the following technical solution: The testing platform 1 is internally equipped with a testing mechanism, which includes a thermal platform 7. The thermal platform 7 performs high-temperature aging testing on the release film pushed by the positioning mechanism. The testing mechanism includes a lifting screw 14, which is rotatably mounted at the rear center of the protective housing 3 via a bearing. The bottom end of the lifting screw 14 is connected to the rear end of the guide screw 11 on the bottom surface of the testing platform 1 via a bevel gear set 8. The outer wall of the lifting screw 14 is threadedly connected to the rear end of the thermal platform 7, causing the thermal platform 7 to descend when the positioning mechanism moves, thereby performing heating aging testing on the release film after positioning.
[0046] The testing mechanism includes a lifting slide bar 15, which is fixedly installed on the left and right sides of the front interior of the protective box 3. The symmetrically arranged lifting slide bars 15 slide through the outer end of the closed partition door 16, so that the closed partition door 16 moves up and down against the inner wall of the protective box 3 to achieve heat insulation and sealing protection. The testing mechanism includes a material retrieval window 17, which is opened at the lower front of the protective box 3. The material retrieval window 17 is opened and closed by the lifting of the closed partition door 16. The upper end of the closed partition door 16 is fixedly connected to the front end of the heat treatment platform 7. The lifting of the heat treatment platform 7 drives the closed partition door 16 to work synchronously.
[0047] like Figures 3-5 As shown, during the rotation of the guide screw 11 inside the testing platform 1, the lifting screw 14, which is meshed with it, is driven to rotate by the bevel gear group 8 at its rear end. The heat treatment platform 7, which is threadedly connected to the lifting screw 14, is limited by the protective box 3 so that the heat treatment platform 7 can move downward and approach the positioned release film. The heat treatment platform 7 heats and bakes the release film to achieve simulated high-temperature weather resistance testing.
[0048] Furthermore, the continuously moving rearward support base plate 4 drives the positioned release film to move into the interior of the protective box 3, while the downward moving heat treatment platform 7 drives the front fixedly connected closed partition door 16 to move downward. The closed partition door 16 is limited by the lifting slide rod 15 that slides through the outer end, so that the material opening 17 on the front of the protective box 3 can be closed through the closed partition door 16, ensuring that the temperature during subsequent weather resistance testing is stored inside the protective box 3.
[0049] Example 3: In order to solve the problems existing in the weather resistance testing of release films, this example discloses the following technical solution: the testing mechanism includes an acid storage tank 18, and the acid storage tank 18 is fixedly installed on the left and right sides inside the positioning base plate 13. A spray sleeve 19 is fixedly installed in the middle of the positioning base plate 13. The rear end of the spray sleeve 19 is connected to the acid storage tank 18 through a one-way infusion pipe 20. At the same time, a pusher rod 21 is elastically slidably provided inside the spray sleeve 19.
[0050] The front end of the push rod 21 included in the testing mechanism is fixedly connected to the protrusion on the bottom surface of the support base plate 4. When the push rod 21 moves, it squeezes the corrosive acid inside the spray sleeve 19. The rear end of the spray sleeve 19 is connected to the spray assembly 22 inside the support base plate 4. The spray assembly 22 sprays the corrosive acid onto the release film covering the top surface of the support base plate 4, thereby simulating the weather resistance of different usage scenarios. The testing mechanism includes a one-way return pipe 23, which connects the support base plate 4 and the acid storage tank 18, thereby recycling the acid after the simulated corrosion spray into the acid storage tank 18 for reuse.
[0051] like Figure 6 , Figure 10 As shown, during the backward sliding process of the support base plate 4 above the testing platform 1, it drives the push plug rod 21 fixedly connected to the bottom surface to move into the spray sleeve 19, thereby squeezing the acid inside the spray sleeve 19 and delivering it to the spray assembly 22 that is connected through the support base plate 4, so that the release film covering the top surface of the support base plate 4 can be sprayed through the spray assembly 22, thereby simulating the corrosive effect of acidic liquid in daily use environment.
[0052] Furthermore, after the release film is tested, the support plate 4 moves the release film forward, and at the same time moves the fixedly connected push rod 21 away from the spray sleeve 19, so that its interior is under negative pressure. Then, acid is drawn from the acid storage tank 18 through the through-connected one-way infusion pipe 20. At this time, the acid storage tank 18 is also under negative pressure. Then, the acid stored in the support plate 4 after spraying is drawn through the one-way return pipe 23, so that it can be returned to the acid storage tank 18 for recycling, reducing consumables and improving the testing effect.
[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
