Description

[Technical field]

[0001] The present application belongs to the technical field of photovoltaic material detection, and in particular, relates to a simulation evaluation device for coiled materials. [Background technology]

[0002] With the development of the photovoltaic industry, the demand for photovoltaic backplanes as an important component of photovoltaic modules is increasing. Currently, there are two main types of backplane products on the market: coated and composite. T / KPC or CPC structure photovoltaic backplanes are coated or composited on the substrate, and then cured in a drying oven to be rolled into hundreds or thousands of meters of coils for transportation. During transportation, the coating in the center of the coil is often squeezed by the outer ring backplane. When the coating is not fully cured or the inner and outer coatings are not well matched, the coatings are prone to sticking and embossing. And as the temperature rises, this problem becomes more serious, resulting in huge economic losses.

[0003] In response to the above problems, the existing simulation evaluation device for coil embossing and sticking often requires a large number of coils to be placed in a curing chamber with a preset temperature for accelerated simulation evaluation when evaluating whether the coating at the center of the coil will be broken and embossed under pressure. This is usually time-consuming and inflexible, and also consumes a lot of manpower, materials and energy, resulting in a high overall verification cost.

[0004] Therefore, the inventors believe that it is necessary to produce a device that can simulate the coil under adjustable external conditions (such as pressure, temperature, etc.) to evaluate the critical conditions under which problems such as embossing and sticking may occur in the center of the coil, so as to obtain preliminary evaluation data for a certain production batch of photovoltaic coils in advance at the laboratory level, thereby reducing economic losses. [Utility Model Content]

[Specific implementation method]

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In the actual transportation process, for coated and composite photovoltaic backsheets, if the coating is not fully cured or the inner and outer coatings (fluorine films) are not well matched, it is easy to cause adhesion and embossing between the coating (or the coating and the fluorine film). Therefore, it is necessary to simulate and evaluate the pressure, temperature and other effects on the coating at the center of the coil, so as to distinguish the corresponding critical values ​​of each influencing factor for the coil at the laboratory level, and further prevent and avoid them to reduce economic losses. In the simulation test process, the changes in pressure and temperature are the main control factors. In the relevant scheme, on the one hand, the pressure control is adjusted quickly and intuitively; on the other hand, the temperature and the stacking method between the coils are also important control factors. If all the more important influencing factors can be fully tested and evaluated in an experimental device, it will be able to greatly improve the understanding and control of the critical values ​​corresponding to the various influencing factors of the coil products, so as to effectively avoid and control them during the actual transportation process to reduce possible economic losses.

[0030] According to the relevant requirements of simulation evaluation, this application provides an experimental device, please refer to Figure 1 .in, Figure 1 1 is a schematic diagram of a simulation evaluation device for coiled materials in one embodiment of the present application. The experimental device of the present application can evaluate the impact of coiled materials under different conditions by setting multiple components simulating different test conditions. The experimental device includes a box 600, and the box 600 includes a first pressing component 100, a second pressing component 200, a supporting component 300, a fixing component 800 and a counterweight 400.

[0031] The box 600 serves as a carrier and protective shell for the entire device, and the first lamination component 100, the second lamination component 200, and the support component 300 are orderly and firmly placed in the box 600. The box 600 provides good protection for the experimental device, and can effectively prevent the influence of external factors on the test process, such as dust, moisture, etc., so as to ensure the accuracy and reliability of the test. In this embodiment, the shape of the box can be selected as a rectangular parallelepiped, and its specific size can be selected and adjusted according to the size of the test coil. At the same time, the length and width directions of the box 600 are both arranged along the horizontal direction. The existence of the box 600 also makes the operation of the experimental device more convenient. You only need to open the rotating door on the box 600 to easily place the coil to be evaluated, adjust the first and second lamination components, and observe the test process, thereby simplifying the operation process and improving the test efficiency.

[0032] In the box 600, the first pressing component 100 and the second pressing component 200 are arranged corresponding to each other, and the pressing direction of the first pressing component 100 and the second pressing component 200 is arranged along the height direction of the box 600. The coil to be evaluated is placed between the first pressing component 100 and the second pressing component 200 to be pressed, and the first pressing component 100 is located below the coil to be evaluated, and the second pressing component 200 is located above the coil to be evaluated, so as to ensure that the pressure distribution of the coil during the test has good uniformity and accuracy, thereby improving the accuracy of the test. In this embodiment, the first pressing component 100 is arranged on the bottom surface of the box 600 in a fixed welding manner to ensure that it always maintains a stable and difficult to move state in the box 600, and the coil is placed on the upper surface of the first pressing component 100, and then the second pressing component 200 is driven to move in the direction close to the first pressing component 100, so as to simulate the test conditions under the pressure condition of the coil.

[0033] There may be multiple support components 300. In this embodiment, two support components 300 are provided and are symmetrically distributed along the inner center line of the box body 600. The length direction of the support component 300 itself is arranged along the height direction of the box body 600, and is respectively connected to the second pressing component 200 and the first pressing component 100, and the second pressing component 200 can be translated toward or away from the first pressing component 100 through the support component 300.

[0034] The fixing assembly 800 is used to fix the coil to be evaluated. The fixing assembly 800 may be a component structure that supports or limits the coil to be evaluated, and is intended to ensure that the coil to be evaluated can be stably pressed during the press test to avoid uncontrolled slippage. A clamp, a limiting frame, or a bearing member with a fixed limiting function may be selected, so the specific structure of the fixing assembly 800 is not particularly limited.

[0035] In this embodiment, a plurality of fixing components 800 are provided, and each fixing component 800 is arranged equidistantly along the length direction of the box body 600 and arranged on the inner side wall of the box body 600 facing the box door, and each fixing component 800 is located between the second pressing component 200 and the first pressing component 100. The fixing component 800 includes a rotating shaft and a bearing member, the rotating shaft is fixedly connected to the inner side wall of the box body 600 along the width direction of the box body 600, the bearing member is cylindrical, the bearing member is sleeved and rotatably connected to the rotating shaft, ensuring that the central axis of the bearing member and the rotation axis of the rotating shaft coincide with each other, and the bearing member is detachably connected to the rotating shaft. The cross-sectional diameter of the bearing member can be replaced according to the model of the test coil, and the cross-sectional diameter of the bearing member can be selected as 10cm. In the preliminary preparation stage of the test evaluation, the staff will evenly wind the coil to be tested onto the outer side wall of the bearing member, control the thickness of the coil to be about 3 to 5cm, and ensure that the thickness of the coil carried on each set of fixing components 800 is the same, and the error range is controlled within 0.5cm. After the simulation test of the same batch of coils is completed, the carrier carrying the coils can be removed from the rotating shaft, so that the staff can replace the coils wrapped on the outer wall of the carrier. At the same time, when individual carriers are damaged by pressure, it is also convenient for the staff to remove and replace them, thereby improving the overall testing efficiency and fault tolerance of the device. For the setting of the carrier, the staff does not need to place a large number of film materials to be tested that are rolled into a certain diameter in the device for a single test, but use a small amount of film material to be wound on the outer wall of the carrier to achieve a certain measurable thickness, thereby reducing the test cost.

[0036] The counterweight 400 is detachably connected to the second pressing part 200, and is used to adjust the pressure weight of the second pressing part 200. At the same time, the counterweight 400 can be set to multiple, and are respectively located at different positions on the upper surface of the second pressing part 200. If the counterweights 400 in the corresponding areas are set to different weights, it is possible to select the counterweight 400 of the target weight, thereby flexibly adjusting the pressure weight of the second pressing part 200, and further realizing accurate control of the test pressure of the device.

[0037] Reference Figure 2 , Figure 2It is a schematic diagram of the detailed structure of the telescopic rod in an embodiment of the present application. The support component 300 includes a support portion 310 and a limit portion 320, the limit portion 320 is vertically penetrated in the second pressing component 200, and the support portion 310 is connected to the lower surface of the second pressing component 200, so as to support and lift the second pressing component 200. The above structure limits the horizontal movement of the pressing component, and jointly realizes the precise support and positioning of the second pressing component 200, and prevents the poor pressing effect of the coil due to the offset of the pressing component, and further makes the test data lose reference value. In this embodiment, the support component 300 is a telescopic rod structure, and the limit portion 320 in the telescopic rod is specifically selected as a limit rod, and a space for the limit rod to pass through is reserved in the second pressing component 200. The support portion 310 can be driven by a motor-related driving member to move up and down. At the same time, the support component 300 is also provided with a plurality of, and in this embodiment, it is specifically provided with two, and is respectively located on both sides of the second pressing component 200 along the length direction of the box body 600. The advantages of this arrangement include: the design of the two telescopic rods being linked to each other enables the support component 300 to be telescopically adjusted according to the test requirements, thereby adapting to different batches and models of coils to be evaluated, improving the flexibility and applicability of the device; the cooperation between the support part 310 and the limit part 320 ensures the stability of the second pressing component 200 during movement, effectively preventing test errors caused by shaking or offset. In addition, the use of a telescopic rod structure for the support component 300 also simplifies the operation process. The staff only needs to adjust the length of the telescopic rod to achieve accurate positioning and support of the second pressing component 200, thereby improving the test accuracy and stability of the experimental device and enhancing its flexibility and ease of use.

[0038] Combined with the design of the disengagement mechanism of the support component 300, the second lamination component 200 can realize an automated and precisely controllable descending action. Combined with the flexible configuration of the counterweight 400, the pressure on the coil to be evaluated can be conveniently and accurately adjusted. This design not only improves the reliability of the test, but also greatly simplifies the operation process, improves the test efficiency, and provides more convenient and efficient technical support for coil testing. This design first enables the device to simulate the test environment under different pressure conditions, providing strong support for evaluating the impact of pressure on the coating at the center position inside the coil. In a preferred technical solution, an elastic mechanism is also included between the support part 310 and the second lamination component 200. During the descent process, after the second lamination component 200 contacts the coil, the support part 310 will continue to descend. Through the elastic mechanism between the support part 310 and the second lamination component 200, the gravity of the second lamination component 200 will gradually be applied to the coil, avoiding excessive impact force on the coil when the support part 310 moves downward and affecting the actual evaluation effect.

[0039] Based on the aforementioned technical solution, a test environment simulating different pressure conditions has been created for the coil. In order to further meet the testing requirements of more changes in external conditions that may be involved in the actual transportation process, the present application has carried out in-depth optimization of the relevant structures inside the box 600 to ensure that it can simulate more test scenarios, so that relevant personnel can obtain a more comprehensive and efficient test solution in the laboratory stage.

[0040] Specifically, refer to Figure 1 and Figure 2 The experimental device also includes a temperature control component 500, which is used to adjust the temperature conditions inside the box 600. By setting the temperature control component 500, the temperature change during the simulation test can be adjusted. In an optimized technical solution, the temperature control component 500 is used to directly adjust the temperature of the first pressing component 100 and / or the second pressing component 200, so that the experimental device can perform pressure tests under different temperature conditions. Since the temperature of the first pressing component 100 or the second pressing component 200 is directly adjusted, the temperature and pressure conditions in the actual transportation environment are more comprehensively simulated. The temperature control component 500 can achieve rapid and stable adjustment of the temperature of the first pressing component 100 and / or the second pressing component 200 through a precise temperature control system. The staff can set the corresponding temperature value according to the test requirements, and the temperature control component 500 will automatically adjust to ensure that the temperature of the pressing component reaches the preset requirements.

[0041] The temperature control component 500 can be set as a component covering the two major functions of heating and cooling. The heating component can be in the form of electric heating wire, electric heating tube or infrared radiation heater, etc., which generates heat through electric current heating, and then transfers the heat to the pressing component. This setting method is simple and direct, and can quickly and effectively increase the temperature of the pressing component. The cooling component can be air-cooled, water-cooled or semiconductor-cooled, and the heat of the pressing component is taken away by circulating cooling medium to achieve a cooling effect. This setting method can effectively reduce the temperature of the pressing component, and is particularly suitable for simulating low-temperature environments or rapid cooling test scenarios. At the same time, the rapid cooling function also helps to reduce the test cycle and improve test efficiency. The setting methods of the heating and cooling components in the temperature control component 500 are diverse and flexible, and can be selected according to actual needs. By accurately controlling the working state of the heating and cooling components, the experimental device can realize pressure testing under different temperature conditions, providing strong support for the comprehensive evaluation of the performance of the coil.

[0042] In addition, in the design of the experimental device, the convenience of data acquisition is fully considered, and multiple data displays are integrated at the required positions. The data displays include but are not limited to weight displays and temperature displays, which can display the key data in the experimental process in real time and provide users with intuitive and accurate information feedback. By integrating data displays at key positions of the device, real-time display and monitoring of data can be achieved. For example, the weight display can display the weight change of the coil to be evaluated when it is under pressure in real time, helping users to accurately understand the stress of the sample; while the temperature display can display the temperature of the pressed parts in real time to ensure that the experiment is carried out under constant temperature conditions, thereby improving the accuracy and reliability of the test data. Such a design not only improves the efficiency of the test experiment, but also greatly simplifies the process of data recording and analysis. By observing the data on the display, the required information can be easily obtained, reducing the operation steps, and reducing the experimental cost and time cost. In addition, the integrated data display also helps to improve the safety of the experiment. By displaying key data in real time, users can promptly detect abnormal situations and take corresponding measures to avoid potential safety risks.

[0043] See also Figure 3 , Figure 3 : is a schematic diagram of the structure of the second lamination component 200 and the first lamination component 100 in another embodiment of the present application. Among them, the second lamination component 200 is equipped with a plurality of first sub-lamination parts 210 in parallel on one side of the first lamination component 100, and similarly, the first lamination component 100 is equipped with a plurality of second sub-lamination parts 220 in parallel on one side of the second lamination component 200. And the counterweight 400 can be set to multiple, and each counterweight 400 is used to adjust the pressure weight of each first sub-lamination part 210. At the same time, the setting mode of one end of the first sub-lamination part 210 and the second sub-lamination part 220 being pressed together can include an arc-shaped contact surface, and the curvature of the arc-shaped contact surface can be set according to the arc surface parameters of the coiled material actually evaluated. By setting the first and second lamination components to multiple sub-lamination parts with arc-pressed end faces, the staff can test coiled materials of different models and batches in the same test process. It should be noted that when testing a single coil at a fixed pressure value, it is necessary to distribute the weight of adjacent counterweights 400 on adjacent first sub-pressing sections 210, so that the two first sub-pressing sections 210 cooperate with the two second sub-pressing sections 220 to perform a press test on the single coil, that is, to apply pressure in four directions around the coil, further simulating the squeezing and collision between the coil and adjacent coils or partitions during transportation, so as to obtain the critical pressure value when the coil is embossed or stuck.

[0044] On the basis of the above technical solution, since the coil may come into contact with objects of different surface shapes during transportation, in order to evaluate the impact of related situations, the surface shapes of the first sub-pressing part 210 and the second sub-pressing part 220 can also be selected as a plane or an inclined plane according to the actual contact situation, thereby fully considering the diversity of the pressure conditions of the coil to be evaluated to meet the test simulation in different specific scenarios. When the first sub-pressing part 210 is set as a plane flush with the second press part 200, it can provide a stable and uniform pressing surface, which is suitable for most conventional coil pressure test scenarios. In addition, when the first sub-pressing part 210 is set as an inclined plane, the inclined plane design can simulate pressing scenarios with a variety of inclination angles, which helps to broaden the application range of the experimental device and enable it to adapt to more special test needs.

[0045] Specifically, the first sub-pressing part 210 is detachably connected to the second press-fitting part 200, and the second sub-pressing part 220 is detachably connected to the first press-fitting part 100. The detachable connection makes it possible to replace different first sub-pressing parts 210 and second sub-pressing parts 220 for different coils, thereby realizing flexible replacement of different surface shapes and materials. According to the test requirements, the first sub-pressing parts 210 and / or second sub-pressing parts 220 of different shapes, sizes or materials can be replaced to simulate different pressing conditions, thereby further improving the scope of application and practicality of the experimental device. The detachable connection design also facilitates the maintenance and cleaning of the experimental device. When the first sub-pressing part 210 or the second sub-pressing part 220 is worn or contaminated due to long-term use, the staff can easily disassemble it for replacement or cleaning without disassembling the entire first press-fitting part 100 or the second press-fitting part 200, which not only simplifies the maintenance process, but also reduces the maintenance cost and improves the service life of the experimental device.

[0046] Specifically, a lighting component 700 is also installed inside the box 600. The lighting component 700 is fixedly connected to the first laminating component 100 or the second laminating component 200. The second laminating component 200 or the first laminating component 100 can be made of transparent material. Under the illumination of the lighting component 700, the defects such as sticking, breaking, and embossing of the sample under different pressures can be observed. In addition, a visual component can also be used to automatically obtain images through the visual component to achieve automated processing. The lighting component 700 or the visual component can also use an angle rotation mechanism to illuminate the coil to be evaluated at different angles or collect image information of the coil to be evaluated. These image information can also be used for subsequent data analysis and processing, and can be used in conjunction with an automated analysis system for data collection and automatic analysis. In addition, by adjusting the angle, more comprehensive and rich observation data can be obtained, which helps to gain a deeper understanding of the performance characteristics and stress behavior of the test coil.

[0047] The implementation principle of the simulation evaluation device for coiled materials in the embodiment of the present application is as follows: before the test, the staff first winds the coiled material to be evaluated to the outside of the carrier and controls the thickness. According to the type of coiled material in a single test, multiple carriers with different coiled materials can be wound in advance, and then each carrier is sequentially installed on the corresponding rotating shaft and placed inside the box 600, so that each corresponding coiled material is between the adjacent second sub-pressing parts 220; then the weight of the counterweight 400 on the corresponding adjacent first sub-pressing part 210 and the heating temperature of the preset temperature control part 500 are adjusted, and the lighting part 700 is turned on to illuminate the coiled material on the first pressing part 200; finally, the second pressing part 200 is driven to move toward the first pressing part 100, and then the drive is canceled. Under the pressure of the counterweight 400, the data display is observed and the critical pressure value when the coiled material is sticky and imprinted at a specific temperature is recorded.

[0048] After the test is finished, the counterweight 400 is withdrawn and the telescopic rod is raised and reset, so that the upper pressing part 200 is separated from the lower pressing part 100, so that the coiled material after the test can be taken out and the relevant components and parts can be cleaned. The test data is statistically collected to make reference for the control of environmental conditions for subsequent actual transportation and further reduce the economic losses caused.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
