Description

Technical Field

[0001] This application relates to the technical field of experimental equipment, and in particular to an impact testing device. Background Technology

[0002] During the production of photovoltaic (PV) modules, it is often necessary to test various aspects of their performance to ensure they meet the required usage. Taking the impact resistance of PV modules as an example, impact testing equipment is typically used to launch impact objects at the modules to simulate impact conditions and test their impact resistance. However, the test results from most impact testing equipment are relatively limited and cannot meet the testing needs of personnel. Utility Model Content

[0003] This application provides an impact testing device, which aims to solve the technical problem that the test results of existing impact testing devices are relatively limited.

[0004] To address the aforementioned problems, this application provides an impact testing device, comprising: a support mechanism, a temperature regulation mechanism, and a launching mechanism; the support mechanism supports a photovoltaic module; the temperature regulation mechanism cooperates with the support mechanism and is used to regulate the temperature of at least a portion of the photovoltaic module; the temperature regulation mechanism includes: a first regulating component and a second regulating component; the first regulating component is connected to the photovoltaic module and can apply voltage to the photovoltaic module after being powered on, thereby raising the temperature of the photovoltaic module; the second regulating component can self-heat and transfer heat to the photovoltaic module after being powered on, thereby raising the temperature of at least a portion of the photovoltaic module; the launching mechanism is disposed around the support mechanism and is used to launch an impactor at the photovoltaic module.

[0005] In the above scheme, by setting the temperature regulation mechanism to have a first regulation component for applying voltage to the photovoltaic module to raise the temperature of the photovoltaic module, and a second regulation component for transferring heat to the photovoltaic module to raise the temperature of at least a part of the photovoltaic module, the impact testing device can use the temperature regulation mechanism to simulate the real high temperature environment such as the photovoltaic module heating up and local hot spots in the working state, so as to obtain the real impact resistance of the photovoltaic module in application scenarios such as high temperature and hot spots, thereby improving the comprehensiveness, accuracy and reliability of the test results of the impact testing device.

[0006] In some embodiments, the support mechanism has a support surface for placing photovoltaic modules, and the second adjustment component includes: a heating element disposed on the support mechanism; the orthographic projection of the heating element on the support surface covers at least a portion of the support surface, and can self-heat and transfer heat to the photovoltaic module after being powered on, so as to raise the temperature of at least a portion of the photovoltaic module.

[0007] Therefore, the second regulating component can transfer heat to the photovoltaic module through the heating element, and since the orthographic projection of the heating element can cover at least a part of the bearing surface, at least a part of the photovoltaic module can be heated to meet the testing requirements for overall or partial heating of the photovoltaic module.

[0008] In some embodiments, the orthographic projection of the heating element on the bearing surface covers a portion of the bearing surface, and the number of heating elements is at least one; the heating element is movably disposed on the bearing mechanism and can move within the coverage area of ​​the bearing surface.

[0009] Therefore, at least one heating element can move within the coverage area of ​​the bearing surface, allowing at least one heating element to move and heat different areas of the photovoltaic module to meet the testing requirements for localized temperature rise of the photovoltaic module.

[0010] In some embodiments, the orthographic projection of the heating element on the bearing surface covers a portion of the bearing surface, and there are multiple heating elements; the orthographic projections of the multiple heating elements on the bearing surface are spaced apart from each other and distributed at different positions on the bearing surface.

[0011] Therefore, multiple heating elements can be distributed at different positions on the bearing surface at intervals, and all of the multiple heating elements can work to heat the entire photovoltaic module, or they can work partially to heat a local part of the photovoltaic module, so as to meet the testing requirements of overall or local temperature rise of the photovoltaic module.

[0012] In some embodiments, the heating element includes: a heating plate, a heating blanket, a heating wire, or an infrared lamp.

[0013] Therefore, the heating element can use heating devices such as heating plates, heating blankets, heating wires or infrared lamps to transfer heat to the photovoltaic module, so as to raise the temperature of at least a part of the photovoltaic module.

[0014] In some embodiments, a thermal pad is also provided between the support structure and the photovoltaic module.

[0015] Therefore, the thermal pad can fill the gap between the support structure and the photovoltaic module to improve the efficiency of heat transfer to the photovoltaic module, which helps to shorten the time required for the photovoltaic module to heat up to the test temperature.

[0016] In some embodiments, the impact testing apparatus includes: a measuring mechanism; the measuring mechanism is connected to the launching mechanism and is capable of measuring the size and / or weight of the impactor.

[0017] Therefore, by connecting a measuring mechanism to the launching mechanism for detecting the size and / or weight of the impactor, the impact testing device can use the measuring mechanism to detect whether the impactor meets the test requirements, thereby improving the accuracy of the impact testing device's test results.

[0018] In some embodiments, the measuring mechanism includes a weight acquisition component and a size detection component; the weight acquisition component is disposed within the launching mechanism and can measure the weight of the impactor loaded into the launching mechanism; the size detection component is disposed within the launching mechanism and can measure the size of the impactor loaded into the launching mechanism.

[0019] Therefore, not only can the weight of the impactor be measured using the weight acquisition component, but the size of the impactor can also be measured using the size detection component, so as to ensure that the weight and size of the impactor meet the test requirements, thereby improving the accuracy of the test results of the impact test device.

[0020] In some embodiments, the weight acquisition component includes a weighing sensor; the weighing sensor is disposed on the mold on which the impactor is placed by the launching mechanism to measure the weight of the impactor.

[0021] Therefore, a weighing sensor can be used to measure the weight of the object to be launched, which is loaded into the launching mechanism, to ensure that the weight of the object to be launched meets the test requirements.

[0022] In some embodiments, the size detection component includes a laser rangefinder sensor; the laser rangefinder sensor is slidably disposed within the transmitting mechanism and can translate to scan the outer surface of the impactor to measure the size of the impactor.

[0023] Therefore, a laser rangefinder can be used to measure the size of the object to be launched, which is installed in the launching mechanism, to ensure that the size of the object meets the test requirements.

[0024] In some embodiments, the impact testing apparatus further includes a temperature detection mechanism; the temperature detection mechanism is connected to the emitting mechanism and can detect the temperature of the photovoltaic module.

[0025] Therefore, the temperature detection mechanism can move with the launching mechanism to detect the temperature of the photovoltaic module, enabling the impact testing device to monitor the temperature of the photovoltaic module and thus facilitate automated testing.

[0026] In some embodiments, the temperature detection mechanism includes an infrared imager connected to the transmitting mechanism.

[0027] Therefore, an infrared imager can be used to follow the movement of the transmitting mechanism and scan the photovoltaic module to detect the temperature of the photovoltaic module.

[0028] In some embodiments, the impact testing apparatus further includes: a moving mechanism; the moving mechanism is connected to the launching mechanism and can drive the launching mechanism to move in two perpendicular directions.

[0029] Therefore, the launching mechanism can be displaced in two perpendicular directions by the moving mechanism, allowing the launching mechanism to move to any position on the bearing surface to meet the impact test requirements of different points of the photovoltaic module.

[0030] In some embodiments, the impact testing apparatus includes: a measuring mechanism and a control mechanism; the measuring mechanism is connected to the launching mechanism and can measure the size and / or weight of the impactor; the control mechanism is electrically connected to the bearing mechanism, the temperature regulating mechanism, the launching mechanism, the measuring mechanism, the temperature detection mechanism, and the moving mechanism respectively.

[0031] Therefore, the control mechanism can control the bearing mechanism, temperature regulation mechanism, emission mechanism, measurement mechanism, temperature detection mechanism and moving mechanism according to preset logic, so that the impact testing device can automatically test the impact resistance of photovoltaic modules.

[0032] In some embodiments, the support mechanism includes: a support platform and a protective frame; the support platform is used to support the photovoltaic module and is provided with a temperature regulation mechanism; the protective frame is disposed on the support platform and surrounds the photovoltaic module.

[0033] Therefore, by setting a protective frame around the photovoltaic module on the bearing platform, the protective frame can block the impacting object and the debris splashed during the impact of the photovoltaic module, thereby improving the test safety of the impact test device.

[0044] In some technical solutions, to test the impact resistance of photovoltaic (PV) modules, the modules are typically placed on an impact testing device, which then launches impacting objects such as ice balls at the modules. This simulates the impact of hail on the PV modules, thus testing their impact resistance under normal conditions. However, the test results from such impact testing devices are often limited and cannot meet the testing needs of PV module engineers.

[0045] Specifically, since photovoltaic (PV) modules are devices that convert light energy into electrical energy, they generate heat under real sunlight, causing the overall temperature of the PV module to rise. Furthermore, because PV modules may have localized defects or be partially shaded by foreign objects, these areas will continue to heat up under real sunlight, leading to hot spots on the PV module.

[0046] Furthermore, since the conductive glass and other components of photovoltaic modules are extremely sensitive to temperature changes, the performance of photovoltaic modules under hail impacts in high-temperature environments and normal-temperature environments is completely different. The aforementioned testing equipment can only test the impact resistance of photovoltaic modules in normal-temperature environments, that is, non-sunlight environments. This results in relatively limited test results from the impact test equipment, which cannot provide effective references for testers.

[0047] To address the aforementioned technical issues, this application discloses an impact testing device. By incorporating a temperature regulation mechanism with a first regulating component for applying voltage to the photovoltaic module to raise its temperature, and a second regulating component for transferring heat to the photovoltaic module to raise the temperature of at least a portion of the module, the impact testing device can simulate real high-temperature environments such as the photovoltaic module's temperature rise and localized abnormal hot spots during operation. This allows the device to obtain the photovoltaic module's true impact resistance under high-temperature and hot-spot application scenarios, thereby improving the comprehensiveness, accuracy, and reliability of the impact testing results.

[0048] It is understood that the impacting object referred to in the embodiments of this application may include: an ice hockey puck, and the photovoltaic module may include: perovskite photovoltaic modules, which are particularly sensitive to temperature differences. That is, the impact testing device disclosed in the embodiments of this application can be used to simulate the situation of photovoltaic modules being hit by hail in a high-temperature environment, so as to test the impact resistance of photovoltaic modules in a high-temperature environment. Of course, in addition to photovoltaic modules, the impact testing device disclosed in the embodiments of this application can also be applied to other devices with similar impact testing needs, and the specific type of impacting object can be adaptively adjusted according to the testing needs of photovoltaic modules.

[0049] Please see Figures 1 to 2 , Figure 1 This is a simplified structural diagram of the impact testing device 10 disclosed in the embodiments of this application. Figure 2 This is a simplified structural diagram of the support mechanism 100 disclosed in the embodiments of this application.

[0050] like Figure 1As shown, the impact testing device 10 may include a support mechanism 100, a temperature regulating mechanism 200, and a launching mechanism 300. The support mechanism 100 supports the photovoltaic module 20, and the temperature regulating mechanism 200 cooperates with the support mechanism 100 to regulate the temperature of at least a portion of the photovoltaic module 20. The launching mechanism 300 is disposed around the support mechanism 100 and is used to launch an impactor 30 at the photovoltaic module 20.

[0051] The support mechanism 100 can be used to install various functional devices required for the impact testing device 10, and a support surface 101 for placing the photovoltaic module 20 can be formed on the outer surface of the support mechanism 100. The shape of the support surface 101 can match the shape of the photovoltaic module 20, and when the photovoltaic module 20 is placed on the support surface 101, the support surface 101 can be located within the coverage area of ​​the photovoltaic module 20.

[0052] For example, when the photovoltaic module 20 is a photovoltaic module, since the shape of a photovoltaic module is generally rectangular, the shape of the supporting surface 101 can also be rectangular, and the area of ​​the supporting surface 101 can be less than or equal to the area of ​​the orthographic projection of the photovoltaic module 20, so that the supporting surface 101 can be located within the coverage area of ​​the photovoltaic module 20. In the context of this application embodiment, the projection direction of the orthographic projection can be perpendicular to the supporting surface 101.

[0053] In some embodiments, the support surface 101 may also be provided with corresponding positioning marks, and the photovoltaic module 20 can be placed on the support surface 101 according to the indication of the positioning marks, so as to improve the placement accuracy of the photovoltaic module 20 on the support surface 101. At the same time, the support surface 101 may also be provided with an origin mark, and the origin mark can be identified by the transmitting mechanism 300, so that the transmitting mechanism 300 can determine its own position according to the origin mark.

[0054] The temperature regulation mechanism 200 can be used to regulate the temperature of the photovoltaic module 20, thereby raising the temperature of the photovoltaic module 20. For example, the temperature regulation mechanism 200 can apply a voltage to the photovoltaic module 20 and form a current loop on the photovoltaic module 20, causing the photovoltaic module 20 to heat up as a whole under the action of the current. And / or, the temperature regulation mechanism 200 can also self-heat and transfer heat to the photovoltaic module 20, thereby raising the temperature of at least a portion of the photovoltaic module 20. Of course, in addition to raising the temperature of the photovoltaic module 20, the temperature regulation mechanism 200 can also cool the photovoltaic module 20.

[0055] The launching mechanism 300 is disposed around the support mechanism 100 and can launch an impactor 30 at the photovoltaic module 20. For example, the launching mechanism 300 is movably disposed above the support surface 101 and can launch the impactor 30 at different positions of the photovoltaic module 20 by moving it to test the impact resistance of different positions of the photovoltaic module 20. The launching mechanism 300 may have a cavity for holding the impactor 30 and can launch the impactor 30 from the cavity in a predetermined manner to hit the photovoltaic module 20 for impact testing.

[0056] In some embodiments, besides being fixedly or movably disposed above the bearing surface 101, the launching mechanism 300 can also be fixedly or movably disposed at other positions of the bearing mechanism 100, and can launch an impact object 30 onto the bearing surface 101 so that the impact object 30 falls parabolically onto the photovoltaic module 20 for impact testing. That is, the placement of the launching mechanism 300 can be adjusted according to design requirements, and the launch trajectory of the impact object 30 can also be adjusted according to design requirements. This embodiment will not list and describe them one by one.

[0057] It is understood that the specific structure of the launching mechanism 300 can be adaptively adjusted according to design requirements. It is sufficient that the launching mechanism 300 can accommodate the impactor 30 and launch the impactor 30 towards the photovoltaic module 20 to complete the test. This embodiment will not be elaborated upon here. Furthermore, when the position of the launching mechanism 300 is fixed, the impactor 30 can be launched to different positions on the photovoltaic module 20 by adjusting the launching angle and launching speed of the launching mechanism 300.

[0058] In the above scheme, by setting a temperature regulation mechanism 200 to regulate the temperature of at least part of the photovoltaic module 20, the impact test device 10 can use the temperature regulation mechanism 200 to simulate different temperature environments to obtain the real impact resistance of the photovoltaic module 20 under different temperature environments, thereby improving the comprehensiveness, accuracy and reliability of the test results of the impact test device 10.

[0059] like Figures 1 to 2 As shown, the support mechanism 100 may include a support platform 110 and a protective frame 120. The support platform 110 supports the photovoltaic module 20 and is equipped with a temperature regulation mechanism 200. The protective frame 120 is disposed on the support platform 110 and surrounds the photovoltaic module 20.

[0060] The support platform 110 may have the aforementioned support surface 101, and in addition to the temperature adjustment mechanism 200, the support platform 110 may also be equipped with various functional devices required by the impact testing device 10. For example, the support platform 110 may have an installation space located below the support surface 101, and the temperature adjustment mechanism 200 and various functional devices required by the impact testing device 10 may be located in this installation space.

[0061] In this embodiment, the support platform 110 can be located below the transmitting mechanism 300, and the aforementioned support surface 101 can be formed on the outer surface of the support platform 110. To reduce the probability of the photovoltaic module 20 shifting position on the support surface 101, the support platform 110 can also be provided with a limiting structure to limit the position of the photovoltaic module 20. For example, a groove can be formed by a partial recess on the support surface 101, and a portion of the structure corresponding to the photovoltaic module 20 can be placed within this groove to limit the position of the photovoltaic module 20.

[0062] The protective frame 120 can be set at the edge of the support platform 110 and can be set around the photovoltaic module 20. At the same time, the protective frame 120 can also protrude a certain height on the support platform 110 and can block the splashes generated when the photovoltaic module 20 and the impacting object 30 collide, such as glass shards or ice shards, so as to improve the testing safety of the impact testing device 10.

[0063] Furthermore, the protective frame 120 may include a frame body 121 and a baffle 122. The frame body 121 may be connected to the edge of the support platform 110, while the baffle 122 may be mounted on the frame body 121 and may be positioned around the support surface 101. The baffle 122 may be a transparent acrylic sheet to allow testers to observe the impact on the photovoltaic module 20.

[0064] In some embodiments, the baffle 122 may not be limited to a transparent acrylic sheet. Whether the baffle 122 is transparent and the material used can also be adjusted according to design requirements. This embodiment will not list them all here. In addition, the specific structure of the protective frame 120 can also be adjusted according to design requirements, and is not limited to the solutions in the above embodiments.

[0065] In the above scheme, by setting a protective frame 120 around the bearing surface 101 on the bearing platform 110, the protective frame 120 can block the debris splashed out when the impacting object 30 and the photovoltaic module 20 collide, so as to improve the test safety of the impact test device 10.

[0066] In some embodiments, the support mechanism 100 may further include an operating table 130 located on one side of the support platform 110. The operating table 130 may be electrically connected to the functional components of the impact testing device 10 and may have buttons and a touch screen for operation by the test personnel, so that the test personnel can adjust the impact testing device 10 through the operating table 130.

[0067] In some embodiments, the control panel 130 may be directly integrated onto the support platform 110, and is not limited to a structure independent of the support platform 110. That is, the support platform 110 may be equipped with the aforementioned buttons and touch screen, allowing testers to directly adjust the impact testing device 10 on the support platform 110.

[0068] like Figure 1 As shown, in order to regulate the temperature of the photovoltaic module 20, the temperature regulation mechanism 200 may include a first regulation component 210. The first regulation component 210 may be connected to the photovoltaic module 20 and may apply voltage to the photovoltaic module 20 after power is supplied, thereby raising the temperature of the photovoltaic module 20.

[0069] The first adjustment component 210 can be mounted on the support mechanism 100, such as within the installation space of the support platform 110. The first adjustment component 210 can be powered on and can apply voltage to the photovoltaic module 20 after being powered on. For example, the first adjustment component 210 can be electrically connected to the internal power supply of the impact testing device 10, i.e., the battery module of the impact testing device 10. And / or, the first adjustment component 210 can also be directly electrically connected to an external power supply through the circuit structure on the support platform 110. When the first adjustment component 210 can be simultaneously powered on by both the internal and external power supplies, the internal power supply can serve as a backup power supply to be activated when the external power supply fails.

[0070] The positive and negative terminals of the photovoltaic module 20 can be led out through a junction box and electrically connected to the first regulating component 210. When the first regulating component 210 is powered on, it applies voltage to the photovoltaic module 20, forming a current loop and causing the photovoltaic module 20 to heat up under the influence of the current. Simultaneously, the first regulating component 210 can adjust the current magnitude and the energizing time to control the temperature of the photovoltaic module 20. In this way, the first regulating component 210 can simulate the working scenario of the photovoltaic module 20 generating electricity and heating up under real sunlight, allowing for testing of the photovoltaic module 20's actual shock resistance under high-temperature environments.

[0071] It is understood that, in addition to being electrically connected through the aforementioned junction box, the first regulating component 210 and the photovoltaic module 20 can also be electrically connected through other connection methods. As long as the first regulating component 210 is powered on, it can apply voltage to the photovoltaic module 20 to form a current loop to heat the photovoltaic module 20 as a whole. This embodiment will not list them one by one.

[0072] In the above scheme, by setting the first regulating component 210 to be energized, voltage can be applied to the photovoltaic module 20, and a current loop can be formed to heat the photovoltaic module 20 as a whole. This allows the photovoltaic module 20 to be subjected to an impact test after being heated to a predetermined temperature that matches the high temperature environment. After the test, the true impact resistance of the photovoltaic module 20 under high temperature environment can be obtained, thereby improving the comprehensiveness, accuracy and reliability of the test results of the impact test device 10.

[0073] like Figure 1 As shown, in order to regulate the temperature of the photovoltaic module 20, the temperature regulation mechanism 200 may further include a second regulation component 220. The second regulation component 220 can generate heat itself after being powered on and transfer heat to the photovoltaic module 20, thereby raising the temperature of at least a portion of the photovoltaic module 20.

[0074] The second regulating component 220 can also be disposed on the support mechanism 100, such as within the installation space of the support platform 110, and can be located below the support surface 101. The second regulating component 220 can also be disposed close to the support surface 101 to facilitate heat transfer from the second regulating component 220 to the photovoltaic module 20. Since the second regulating component 220 transfers heat to the photovoltaic module 20 by means of self-heating upon energization, the heating range of the second regulating component 220 can be controlled by setting its heat radiation range, i.e., its coverage area on the support surface 101, so that at least a portion of the photovoltaic module 20 is heated.

[0075] Furthermore, in order to simulate the hot spot phenomenon of the photovoltaic module 20, the second regulating component 220 can locally heat the photovoltaic module 20. That is, after the first regulating component 210 heats the photovoltaic module 20 as a whole to simulate the photovoltaic module 20 generating electricity under sunlight, the second regulating component 220 can locally heat a predetermined position of the photovoltaic module 20, so that the predetermined position of the photovoltaic module 20 can continue to rise in temperature to simulate the hot spot phenomenon of localized heating of the photovoltaic module 20, thereby realizing the impact test of the hot spot position of the photovoltaic module 20.

[0076] Alternatively, considering that the first regulating component 210 has an upper limit on the current applied to the photovoltaic module 20, the second regulating component 220 can also heat the photovoltaic module 20 as a whole. That is, when the heating temperature of the first regulating component 210 reaches the upper limit, the second regulating component 220 can heat the photovoltaic module 20 as a whole, so that the photovoltaic module 20 as a whole can be heated to the test temperature to meet the test requirements of realistically simulating a high-temperature environment.

[0077] For example, if localized heating of the photovoltaic module 20 is required, the second regulating component 220 can be set to a smaller size, allowing it to cover only a portion of the supporting surface 101. This allows it to self-heat and transfer heat to the corresponding area of ​​the photovoltaic module 20 after power is applied, thus achieving localized heating of the photovoltaic module 20. Similarly, if heating of the entire photovoltaic module 20 is required, the second regulating component 220 can be set to a larger size, allowing it to cover the entire supporting surface 101. This allows it to self-heat and transfer heat to the entire photovoltaic module 20 after power is applied, thus achieving overall heating of the photovoltaic module 20.

[0078] In some embodiments, when the second adjustment component 220 can only locally heat the photovoltaic module 20, considering that different points of the photovoltaic module 20 may have impact testing requirements, the second adjustment component 220 can also be movably arranged in the installation space, so that the second adjustment component 220 can be moved to different positions to transfer heat to the photovoltaic module 20, so as to heat the local corresponding to different points of the photovoltaic module 20, thereby meeting the impact testing requirements of different points of the photovoltaic module 20.

[0079] In some embodiments, besides using a movable second adjustment component 220 to heat different points of the photovoltaic module 20 locally, multiple second adjustment components 220 can also be used to heat different points of the photovoltaic module 20 locally. The orthographic projections of the multiple second adjustment components 220 onto the supporting surface 101 can be distributed at different positions on the supporting surface 101, covering most or all of the area of ​​the supporting surface 101, ensuring that the heating range of the multiple second adjustment components 220 can cover different points of the photovoltaic module 20.

[0080] Furthermore, when a certain point on the photovoltaic module 20 needs to be tested, one or more second adjustment components 220 corresponding to that point can be controlled to operate, so as to heat the area at that point to a predetermined temperature for testing. At the same time, since the orthographic projection of multiple second adjustment components 220 can cover most or all of the supporting surface 101, all the second adjustment components 220 can also operate simultaneously to heat the entire photovoltaic module 20.

[0081] In the above scheme, by setting the second regulating component 220 to generate heat to the photovoltaic module 20 after being powered on, and to heat the photovoltaic module 20 as a whole or in a localized manner, the second regulating component 220 can continue to heat the photovoltaic module 20 on the basis of the first regulating component 210, so as to meet the test requirements of the photovoltaic module 20 for overall or localized temperature rise, thereby ensuring that the test temperature of the photovoltaic module 20 can match the real high temperature environment.

[0082] In some embodiments, the impact testing device 10 may heat the photovoltaic module 20 using only one of the first adjustment component 210 and the second adjustment component 220, as long as the photovoltaic module 20 can be heated to a predetermined temperature that matches the high-temperature environment. That is, the selection of the first adjustment component 210 and the second adjustment component 220 by the impact testing device 10 can be adjusted according to the testing requirements.

[0083] Please combine Figure 1 See Figure 3 , Figure 3 This is a simplified structural diagram of the photovoltaic module 20, the support platform 110, and the second adjustment component 220 disclosed in the embodiments of this application.

[0084] like Figure 1 and Figure 3 As shown, the support mechanism 100 has a support surface 101 for placing the photovoltaic module 20, and the second adjustment component 220 may include a heating element 221 disposed on the support mechanism 100. The orthographic projection of the heating element 221 onto the support surface 101 can cover at least a portion of the support surface 101, and can self-heat and transfer heat to the photovoltaic module 20 after being powered on, thereby raising the temperature of at least a portion of the photovoltaic module 20.

[0085] The heating element 221 can be installed within the mounting space of the support platform 110 and can be located below the support surface 101. Since the heating element 221 transfers heat to the photovoltaic module 20 through self-heating, the heating range of the heating element 221 can be controlled by setting the coverage area of ​​the orthographic projection of the heating element 221 on the support surface 101.

[0086] Furthermore, when the orthographic projection of the heating element 221 on the bearing surface 101 only covers a portion of the bearing surface 101, the heating element 221 can heat only a local area of ​​the photovoltaic module 20. When the orthographic projection of the heating element 221 on the bearing surface 101 covers the entire bearing surface 101, the heating element 221 can heat the entire photovoltaic module 20.

[0087] In the above scheme, the heating element 221 is configured to generate heat to the photovoltaic module 20 after being powered on, and the orthogonal projection of the heating element 221 on the bearing surface 101 can cover at least a part of the bearing surface 101, so that the heating element 221 can heat the photovoltaic module 20 as a whole or in part, in order to meet the test requirements of the photovoltaic module 20 for overall or partial temperature rise.

[0088] Please see Figures 4 to 5 , Figure 4 This is another simplified structural diagram of the photovoltaic module 20, the support platform 110, and the second adjustment component 220 disclosed in the embodiments of this application. Figure 5 This is another simplified structural diagram of the photovoltaic module 20, the support platform 110, and the second adjustment component 220 disclosed in the embodiments of this application.

[0089] like Figures 4 to 5 As shown, the orthographic projection of the heating element 221 onto the bearing surface 101 can cover a portion of the bearing surface 101, and the number of heating elements 221 is at least one. Simultaneously, the heating element 221 is movably mounted on the bearing mechanism 100 and can move within the coverage area of ​​the bearing surface 101.

[0090] Since the orthographic projection of the heating element 221 on the bearing surface 101 only covers a portion of the bearing surface 101, the heating element 221 can only heat a localized area of ​​the photovoltaic module 20. Therefore, in order to achieve heating of different points on the photovoltaic module 20 by the heating element 221, the heating element 221 can be moved within the installation space, allowing it to be moved to different positions on the bearing surface 101 to heat the corresponding localized areas of the photovoltaic module 20, thereby meeting the impact testing requirements of multiple points on the photovoltaic module 20.

[0091] To enable the movement of the heating element 221 within the installation space, the supporting mechanism 100 may further include a drive module 140 disposed within the installation space of the support platform 110. The drive module 140 may be connected to the heating element 221 and drive it to reciprocate within the installation space. For example, the drive module 140 may be a combination of a motor and a lead screw, and the heating element 221 may be connected to a nut on the lead screw. When the motor drives the lead screw to rotate, the heating element 221 may reciprocate along the lead screw following the nut, thereby enabling the movement of the heating element 221 within the installation space. Simultaneously, the support platform 110 may also be provided with a guide structure such as a slide rail or groove connected to the heating element 221 within the installation space to guide the movement of the heating element 221 within the installation space.

[0092] In some embodiments, the drive module 140 may not be limited to the solutions shown in the above embodiments. For example, the drive module 140 may also be a combination of a cylinder and a connecting rod, and the heating element 221 may be connected to the connecting rod. When the cylinder drives the connecting rod to reciprocate, the heating element 221 can reciprocate along with the connecting rod to realize the movement of the heating element 221 within the installation space. Similarly, the support platform 110 may also be provided with a guide structure such as a slide rail or slide groove connected to the heating element 221 within the installation space to guide the movement of the heating element 221 within the installation space.

[0093] When there is only one heating element 221, the drive module 140 can be a combination of two motors and two lead screws. The drive module 140 can drive the heating element 221 to move in two perpendicular directions through two sets of motors and lead screws respectively. The two moving directions of the heating element 221 can also be parallel to the bearing surface 101 to ensure that the moving range of the heating element 221 can cover the entire bearing surface 101.

[0094] like Figure 4 As shown, in some embodiments, when the orthographic projection of the heating element 221 on the bearing surface 101 coincides with two opposite sides of the bearing surface 101, that is, when the heating element 221 completely covers the bearing surface 101 in the horizontal or vertical direction, the driving module 140 can drive the heating element 221 to move towards the other two opposite sides of the bearing surface 101, that is, in Figure 4 The arrow points in the direction of the reset. In this way, the movement range of the heating element 221 can also cover the entire bearing surface 101, so that the heating element 221 can heat different areas of the photovoltaic module 20, that is, the local areas corresponding to different points of the photovoltaic module 20, by moving.

[0095] When there are multiple heating elements 221, the displacement path of each heating element 221 can be planned so that the movement range of multiple heating elements 221 can jointly cover almost the entire bearing surface 101. For example, the number of heating elements 221 can be... Figure 5 The three shown, and the three heating elements 221, can be driven by the drive module 140 to... Figure 5 The arrows indicate that the three heating elements 221 can move in the direction of resetting, so that their movement range can cover almost the entire bearing surface 101, in order to meet the heating test requirements of different points of the photovoltaic module 20.

[0096] In the above scheme, at least one heating element 221 is movably mounted on the support mechanism 100, and the heating element 221 can move within the coverage area of ​​the support surface 101, so that at least one heating element 221 can heat different areas of the photovoltaic module 20, that is, the local areas corresponding to different points of the photovoltaic module 20, in order to meet the test requirements of local temperature rise of the photovoltaic module 20.

[0097] In some embodiments, in addition to configuring a drive module 140 to drive the heating element 221 to move in a direction parallel to the bearing surface 101, a new drive module 140 can also be configured to drive the heating element 221 to move in a direction perpendicular to the bearing surface 101, thereby adjusting the distance between the heating element 221 and the bearing surface 101 and controlling the rate at which the heating element 221 transfers heat to the photovoltaic module 20. That is, the farther the heating element 221 is from the bearing surface 101, the slower the rate at which the heating element 221 transfers heat to the photovoltaic module 20. The closer the heating element 221 is to the bearing surface 101, the faster the rate at which the heating element 221 transfers heat to the photovoltaic module 20.

[0098] Please see Figure 6 , Figure 6 This is another simplified structural diagram of the photovoltaic module 20, the support platform 110, and the second adjustment component 220 disclosed in the embodiments of this application.

[0099] like Figure 6 As shown, the orthographic projection of the heating element 221 on the bearing surface 101 can cover a portion of the bearing surface 101, and there are multiple heating elements 221. Among them, the orthographic projections of the multiple heating elements 221 on the bearing surface 101 are spaced apart from each other and can be distributed at different positions on the bearing surface 101.

[0100] When the orthographic projection of the heating element 221 on the bearing surface 101 can only cover a part of the bearing surface 101, that is, when the heating element 221 can only heat a part of the photovoltaic module 20, in addition to heating different points of the photovoltaic module 20 by moving the aforementioned heating element 221, it is also possible to heat different points of the photovoltaic module 20 by setting multiple fixed heating elements 221. This can omit the design of the aforementioned drive module 140, thereby simplifying the structure of the impact testing device 10.

[0101] For example, when the shape of the bearing surface 101 is Figure 6 When the rectangle shown is used, the number of heating elements 221 can be [number missing]. Figure 6 The diagram shows 18 heating elements 221. These 18 heating elements 221 can be arranged in 6 rows along the long side of the bearing surface 101, and in 3 columns along the short side. Furthermore, the orthographic projections of the 18 heating elements 221 onto the bearing surface 101 can be evenly distributed at different positions on the bearing surface 101, allowing the orthographic projections of the 18 heating elements 221 to cover almost the entire bearing surface 101.

[0102] It is understandable that the specific number and arrangement of the multiple heating elements 221 can be adaptively adjusted according to the shape and area of ​​the bearing surface 101, and are not limited to... Figure 6 The illustrated solution only requires that the orthographic projections of multiple heating elements 221 on the supporting surface 101 be distributed at different positions on the supporting surface 101 and be able to cover almost the entire supporting surface 101. With this configuration, the areas where different points of the photovoltaic module 20 are located can all fall within the heating range of the multiple heating elements 221.

[0103] Multiple heating elements 221 can heat the photovoltaic module 20 either as a whole or in a localized manner. That is, when the photovoltaic module 20 needs overall heating, multiple heating elements 221 can operate simultaneously. Since the orthographic projection of the multiple heating elements 221 almost covers the entire supporting surface 101, the multiple heating elements 221 can heat the entire photovoltaic module 20. When a specific area of ​​the photovoltaic module 20 needs heating, only one or more heating elements 221 corresponding to that area need to operate to complete the localized heating of the photovoltaic module 20.

[0104] In this embodiment, since the positions of the multiple heating elements 221 are fixed, the multiple heating elements 221 can also be attached to the side of the support platform 110 away from the support surface 101 to reduce or eliminate the air gap between the heating elements 221 and the support platform 110, thereby improving the efficiency of the heating elements 221 in transferring heat to the photovoltaic module 20 through the support platform 110.

[0105] In the above scheme, by setting multiple heating elements 221 to be distributed at different positions on the bearing surface 101 with their orthogonal projections on the bearing surface 101, the heating range of the multiple heating elements 221 can cover the entire photovoltaic module 20, so that the multiple heating elements 221 can heat the photovoltaic module 20 as a whole or in part, thereby meeting the test requirements for the overall or partial temperature rise of the photovoltaic module 20.

[0106] To achieve the heating function of the heating element 221, the heating element 221 may include: a heating plate, a heating blanket, a heating wire, or an infrared lamp. That is, the heating element 221 can specifically be any one of a heating plate, a heating blanket, a heating wire, and an infrared lamp, so that the heating element 221 can self-heat and transfer heat to the photovoltaic module 20 after being powered on, so as to heat the photovoltaic module 20 as a whole or in part. Of course, in addition to the aforementioned heating plate, heating blanket, heating wire, and infrared lamp, the heating element 221 can also be other heating devices with self-heating function when powered on, which will not be listed and described in this embodiment.

[0107] Please see Figure 7 , Figure 7 yes Figure 3 A partial cross-sectional structural diagram of the photovoltaic module 20 and the support platform 110.

[0108] like Figure 7As shown, in order to improve the efficiency of heat transfer from the heating element 221 to the photovoltaic module 20, a heat-conducting pad 150 is also provided between the support mechanism 100 and the photovoltaic module 20.

[0109] The thermal pad 150 can be a high-thermal-conductivity structure such as thermally conductive silicone, and the thermal pad 150 can cover the entire supporting surface 101. The thermal pad 150 can be used to fill the air gap between the supporting surface 101 and the photovoltaic module 20, thereby improving the efficiency of heat transfer from the heating element 221 to the photovoltaic module 20 through the supporting platform 110, thus helping to shorten the time required for the photovoltaic module 20 to heat up to the predetermined temperature.

[0110] In some embodiments, the support platform 110 may have a perforation on the support surface 101, and the thermal pad 150 may cover the perforation on the support surface 101. The heating element 221 can be attached to the thermal pad 150 through the perforation, so that the heating element 221 can directly transfer heat to the photovoltaic module 20 through the thermal pad 150, thereby improving the efficiency of heat transfer from the heating element 221 to the photovoltaic module 20. Of course, in some embodiments, the heating element 221 may also be directly attached to the photovoltaic module 20.

[0111] In some embodiments, the temperature regulation mechanism 200 may further include a third regulation component, which can be used to reduce the temperature of the photovoltaic module 20 to achieve the cooling function of the temperature regulation mechanism 200. For example, the third regulation component may be a wind-cooled structure such as a fan, or a liquid-cooled structure such as a cooling plate, so that the third regulation component can cool the photovoltaic module 20 by wind cooling or liquid cooling to meet different testing requirements of the photovoltaic module 20. For example, the third regulation component can not only be used to cool the photovoltaic module 20 after it has been heated, but also to cool the photovoltaic module 20 at room temperature to simulate the low temperature of the photovoltaic module 20 in a nighttime environment, thereby testing the real shock resistance of the photovoltaic module 20 at low temperatures.

[0112] Please refer to it again. Figure 1 To confirm whether the impactor 30 meets the test requirements, the impact test device 10 may further include a measuring mechanism 400. The measuring mechanism 400 is connected to the launching mechanism 300 and can measure the size and / or weight of the impactor 30.

[0113] The measuring mechanism 400 can be connected to the launching mechanism 300 and can detect the impactor 30 installed in the launching mechanism 300 to determine whether the impactor 30 meets the test requirements. Specifically, the measuring mechanism 400 can detect the weight and / or dimensions of the impactor 30 and determine whether the impactor 30 meets preset standards based on the detection results. When the impactor 30 meets the preset standards, the launching mechanism 300 can launch the impactor 30 towards the photovoltaic module 20. When the impactor 30 does not meet the preset standards, the launching mechanism 300 can remove the impactor 30 from the cavity to accommodate the next impactor 30.

[0114] Furthermore, the measuring mechanism 400 can also be disposed within the launching mechanism 300, such as within the cavity of the launching mechanism 300, and can detect the impactor 30 within the cavity to determine whether the impactor 30 meets the test requirements. Compared to the scheme where the measuring mechanism 400 detects the impactor 30 before it is loaded into the launching mechanism 300, detecting it after it is loaded into the launching mechanism 300 can shorten the interval between the detection time and the launch time, thereby reducing the probability that the impactor 30 will further melt during this interval, causing it to fail the impact test requirements at launch.

[0115] In the above scheme, by connecting a measuring mechanism 400 for detecting the size and / or weight of the impactor 30 to the launching mechanism 300, the impact testing device 10 can use the measuring mechanism 400 to detect whether the impactor 30 meets the test requirements, thereby improving the accuracy of the test results of the impact testing device 10.

[0116] To measure the weight and dimensions of the impactor 30, the measuring mechanism 400 may include a weight acquisition component 410 and a dimension detection component 420. The weight acquisition component 410 may be located within the launching mechanism 300 and can measure the weight of the impactor 30 loaded within the launching mechanism 300. The dimension detection component 420 may also be located within the launching mechanism 300 and can measure the dimensions of the impactor 30 loaded within the launching mechanism 300.

[0117] The weight acquisition component 410 can be disposed within the cavity of the launching mechanism 300 into the impactor 30. When the impactor 30 is inserted into the cavity of the launching mechanism 300, the weight acquisition component 410 can be subjected to the pressure transmitted by the impactor 30, and the weight of the impactor 30 can be calculated from the detected pressure data.

[0118] The size detection component 420 can also be disposed within the cavity of the launching mechanism 300 into the impactor 30. When the impactor 30 is inserted into the cavity of the launching mechanism 300, the size detection component 420 can scan or identify the impactor 30 to calculate the size of the impactor 30 based on the scanning or identification results.

[0119] In the above scheme, by setting a weight acquisition component 410 to measure the weight of the impactor 30 and setting a size detection component 420 to detect the size of the impactor 30, the impactor 30 can only be launched from the launching mechanism 300 when it meets the test requirements, thereby improving the accuracy of the test results of the impact test device 10.

[0120] In some embodiments, the measuring mechanism 400 may include only one of the weight acquisition component 410 and the size detection component 420. For example, the measuring mechanism 400 may include only the weight acquisition component 410, and the size of the impactor 30 can be estimated from the weight measured by the weight acquisition component 410 and the type of the impactor 30. Similarly, the measuring mechanism 400 may include only the size detection component 420, and the size of the impactor 30 can be estimated from the size detected by the size detection component 420 and the type of the impactor 30. For example, when the impactor 30 is a hockey puck, the density parameter of the hockey puck can be input into the impact testing device 10 to estimate the weight of the impactor 30 from its size and density.

[0121] To realize the weighing function of the weight acquisition component 410, the weight acquisition component 410 may include a weighing sensor 411. The weighing sensor 411 may be equipped with a transmitting mechanism 300 placed on the mold of the impactor 30, and can measure the weight of the impactor 30.

[0122] The cavity of the launching mechanism 300 may contain a mold slightly larger than the impactor 30. When the impactor 30 is inserted into the cavity of the launching mechanism 300, it can be placed on the mold within the cavity. The weighing sensor 411 can simultaneously receive pressure from both the impactor 30 and the mold to measure the total weight of the impactor 30 and the mold. In subsequent calculations, the known weight of the mold can be subtracted to calculate the weight of the impactor 30.

[0123] With this setup, the weight of the object to be launched 30, which is loaded into the launching mechanism 300, can be measured using the weighing sensor 411 to ensure that the weight of the object to be launched 30 meets the test requirements.

[0124] To realize the size detection function of the size detection component 420, the size detection component 420 may include a laser rangefinder 421. The laser rangefinder 421 can be slidably disposed in the space of the emitting mechanism 300 and can translate and scan the outer surface of the impactor 30 to measure the size of the impactor 30.

[0125] For example, the cavity of the transmitting mechanism 300 may have a sliding rail and a slider with a sliding fit, and the laser rangefinder 421 may be connected to the slider and slide on the slide rail via the slider to translate and scan the outer surface of the impactor 30, so as to calculate the diameter of the impactor 30 by recording the maximum obstruction distance. That is, when the laser beam emitted by the laser rangefinder 421 scans to the middle position of the impactor 30, the receiving end of the laser rangefinder 421 can be completely blocked, and the translation distance of the laser rangefinder 421 at this time is the diameter of the impactor 30. In this embodiment, the sliding of the laser rangefinder 421 may be driven by a drive structure such as a piezoelectric motor, a voice coil motor, and a cylinder.

[0126] With this setup, the laser rangefinder 421 can be used to measure the size of the launching impactor 30 installed in the launching mechanism 300, so as to ensure that the size of the launching impactor 30 meets the test requirements.

[0127] In some embodiments, in addition to the laser rangefinder 421 described above, the size detection component 420 can also detect the size of the impactor 30 using an image sensor. That is, the image sensor can take a picture of the impactor 30 and calculate the size of the impactor 30 using parameters such as the distance between the corresponding pixels of the impactor 30 in the image.

[0128] like Figure 1 As shown, in order to monitor the temperature of the photovoltaic module 20, the impact testing device 10 may further include a temperature detection mechanism 500. The temperature detection mechanism 500 may be connected to the emitting mechanism 300 and can detect the temperature of the photovoltaic module 20.

[0129] Since the temperature detection mechanism 500 is connected to the transmitting mechanism 300, it can move along with the transmitting mechanism 300 to detect the temperature of different areas of the photovoltaic module 20. Simultaneously, when the temperature detection mechanism 500 detects that the photovoltaic module 20 as a whole or in a part has reached a predetermined temperature, it can send a signal to the control center of the impact testing device 10, i.e., the control mechanism 700 described later, to control the transmitting mechanism 300 to move to a predetermined position and launch the impactor 30 for impact testing. Specifically, the temperature detection mechanism 500 can be a device with temperature detection and position recognition functions, such as an infrared imager.

[0130] In the above scheme, by setting the temperature detection mechanism 500 as an infrared imager, and the temperature detection mechanism 500 can move with the transmitting mechanism 300, the temperature detection mechanism 500 can detect the temperature of different areas of the photovoltaic module 20, so as to realize the impact test device 10 to monitor the temperature of the photovoltaic module 20, thereby facilitating the impact test device 10 to perform automated impact testing.

[0131] Please refer to it again. Figure 1 and Figure 2 To enable the launch mechanism 300 to move, the impact testing device 10 may further include a moving mechanism 600. The moving mechanism 600 may be connected to the launch mechanism 300 and may drive the launch mechanism 300 to move in two perpendicular directions.

[0132] The moving mechanism 600 can be connected to the support platform 110, and the moving mechanism 600 may include a driving component 610. The driving component 610 is the same as or similar to the aforementioned driving module 140, and the driving component 610 can also drive the transmitting mechanism 300 to move in two perpendicular directions, allowing the transmitting mechanism 300 to move to any position on the support surface 101 to perform impact tests on different points of the photovoltaic module 20. In this embodiment, both displacement directions of the transmitting mechanism 300 can be parallel to the support surface 101, allowing the transmitting mechanism 300 to translate relative to the support surface 101.

[0133] In some embodiments, the moving mechanism 600 can also drive the emitting mechanism 300 to move in a direction perpendicular to the bearing surface 101, so that the distance between the emitting mechanism 300 and the bearing surface 101 is adjustable to meet the testing requirements of the impactor 30 impacting the photovoltaic module 20 from different heights.

[0134] Please see Figure 1 To achieve automated testing of the impact testing device 10, the impact testing device 10 may further include a control mechanism 700. The control mechanism 700 may be electrically connected to the bearing mechanism 100, the temperature regulating mechanism 200, the launching mechanism 300, the measuring mechanism 400, the temperature detection mechanism 500, and the moving mechanism 600, respectively.

[0135] The control mechanism 700 may include a circuit board and various processors integrated on the circuit board. The control mechanism 700 can be connected to the bearing mechanism 100, temperature regulation mechanism 200, transmitting mechanism 300, measuring mechanism 400, temperature detection mechanism 500, and moving mechanism 600 via flexible circuit boards or signal lines. It can also issue control signals based on the electrical signals fed back from these mechanisms to control the bearing mechanism 100, temperature regulation mechanism 200, transmitting mechanism 300, measuring mechanism 400, temperature detection mechanism 500, and moving mechanism 600 according to preset logic, thereby achieving automated testing of the photovoltaic module 20 by the impact testing device 10. In addition to its functions as described above, the control mechanism 700 can also... Figure 1 In addition to being set independently of the support mechanism 100, the control mechanism 700 can also be set on the support mechanism 100, such as within the installation space of the support platform 110.

[0136] The following is an example illustrating the automated testing of the impact testing device 10. The photovoltaic module 20 can be placed on the bearing surface 101 using a robotic arm or similar picking device, with the glass side of the photovoltaic module 20 facing upwards. After the photovoltaic module 20 is placed, the impact testing device 10 can automatically select the points where the photovoltaic module 20 needs to be impact tested, according to the positions specified in the IEC 61215 standard.

[0137] The impactor 30 can be placed into the launching mechanism 300 using a robotic arm or similar picking device. The measuring mechanism 400 can detect the weight and size of the impactor 30 to determine whether it meets the test standards of 25mm ± 5% in diameter and 7.35g ± 5% in weight. If the impactor 30 is found to be substandard, the launching mechanism 300 can remove it. If the impactor 30 is found to be satisfactory, the launching mechanism 300 can load it into the launching position for subsequent launch according to predetermined requirements once the launch conditions are met.

[0138] After the photovoltaic module 20 is placed on the support surface 101, the temperature regulation mechanism 200 can heat the photovoltaic module 20 to a predetermined temperature, either as a whole or in a part. For example, the first regulation component 210 can apply a positive voltage to the photovoltaic module 20 by energizing a DC power supply and apply a constant current to the photovoltaic module 20 to heat the entire photovoltaic module 20. After the first regulation component 210 has been energized for 30 minutes, the temperature detection mechanism 500 can automatically scan the overall temperature of the photovoltaic module 20 to determine the location and value of the highest temperature point of the photovoltaic module 20.

[0139] After the control mechanism 700 obtains the location and temperature value of the highest temperature point of the photovoltaic module 20 through the temperature detection mechanism 500, if the temperature of the highest temperature point reaches 85℃-100℃, the control mechanism 700 can control the moving mechanism 600 to move the emitting mechanism 300 to the highest temperature point, and then conduct an impact test on the highest temperature position of the photovoltaic module 20 using an impactor 30 with a diameter of 25mm according to the IEC61215 standard.

[0140] If the overall temperature of the photovoltaic module 20 is below 85°C, the second regulating component 220 can be controlled to continue heating the photovoltaic module 20. For example, if the overall temperature of the photovoltaic module 20 is uniform and low, the second regulating component 220 can be controlled to heat the entire photovoltaic module 20 so that an impact test can be performed after the entire photovoltaic module 20 reaches a predetermined temperature.

[0141] If the overall temperature of the photovoltaic module 20 is too high and the temperature is uneven, the second regulating component 220 can be controlled to heat the part of the photovoltaic module 20 with the highest temperature first, and heat the area to a predetermined temperature for impact testing, so as to avoid heating the entire photovoltaic module 20, which would cause the area of ​​the photovoltaic module 20 with a high temperature to overheat.

[0142] It is understood that the automated testing process of the aforementioned impact testing device 10 is merely an illustrative example, and the testing process of the impact testing device 10 can be adjusted according to design requirements. This embodiment does not limit this.

[0143] Finally, in some specific application scenarios, to address the limitation of test results in existing impact testing devices 10, the impact testing device 10 provided in this application embodiment may include: a support mechanism 100, a temperature regulation mechanism 200, and a launching mechanism 300. The support mechanism 100 supports the photovoltaic module 20. The temperature regulation mechanism 200 cooperates with the support mechanism 100 and is used to regulate the temperature of at least a portion of the photovoltaic module 20. The temperature regulation mechanism 200 includes: a first regulating component 210 and a second regulating component 220. The first regulating component 210 is connected to the photovoltaic module 20 and can apply voltage to the photovoltaic module 20 after being energized, so as to raise the temperature of the photovoltaic module 20. The second regulating component 220 can self-heat and transfer heat to the photovoltaic module 20 after being energized, so as to raise the temperature of at least a portion of the photovoltaic module 20. The launching mechanism 300 is disposed on the periphery of the support mechanism 100 and is used to launch an impactor 30 at the photovoltaic module 20. A thermally conductive pad 150 is also provided between the support mechanism 100 and the photovoltaic module 20.

[0144] The impact testing device 10 further includes a measuring mechanism 400, which is connected to the launching mechanism 300 and can measure the size and / or weight of the impactor 30. The measuring mechanism 400 includes a weight acquisition component 410 and a size detection component 420; the weight acquisition component 410 is disposed within the launching mechanism 300 and can measure the weight of the impactor 30 installed within the launching mechanism 300; the size detection component 420 is disposed within the launching mechanism 300 and can measure the size of the impactor 30 installed within the launching mechanism 300.

[0145] The impact testing device 10 further includes: a temperature detection mechanism 500; the temperature detection mechanism 500 is connected to the emitting mechanism 300 and can detect the temperature of the photovoltaic module 20. The impact testing device 10 also includes: a moving mechanism 600; the moving mechanism 600 is connected to the emitting mechanism 300 and can drive the emitting mechanism 300 to move in two perpendicular directions. The impact testing device 10 also includes: a control mechanism 700; the control mechanism 700 is electrically connected to the bearing mechanism 100, the temperature regulating mechanism 200, the emitting mechanism 300, the measuring mechanism 400, the temperature detection mechanism 500, and the moving mechanism 600.

[0146] The impact testing device 10 provided in this application embodiment has a temperature regulation mechanism 200 with a first regulation component 210 for applying voltage to the photovoltaic module 20 to raise the temperature of the photovoltaic module 20, and a second regulation component 220 for transferring heat to the photovoltaic module 20 to raise the temperature of at least a part of the photovoltaic module 20. This allows the impact testing device 10 to simulate the real high-temperature environment of the photovoltaic module 20 under working conditions, such as temperature rise and local abnormal hot spots, so as to obtain the real impact resistance of the photovoltaic module 20 under application scenarios such as high temperature and hot spots, thereby improving the comprehensiveness, accuracy and reliability of the test results of the impact testing device 10.
