[0042] Combination Figure 1 and Figure 2This invention provides a photovoltaic module IV testing device. The IV test, or current-voltage characteristic IV test, is performed on the photovoltaic module. The device includes a light bathing device 1, a solar simulator 2, a through-track 3, and a mounting bracket 4. The light bathing device 1 is positioned on one side of the solar simulator 2. The through-track 3 connects the bottom of the light bathing device 1 and the solar simulator 2. A sliding door 5 is located between the light bathing device 1 and the solar simulator 2, vertically positioned above the through-track 3. The mounting bracket 4 is connected to the through-track 3, and the photovoltaic module 6 is connected to the mounting bracket 4. When the sliding door 5 is open, the photovoltaic module 6 can move on the through-track 3. Specifically, the light bathing device 1 performs a light bathing treatment on the photovoltaic module 6 to stabilize its electrical performance. The solar simulator 2 performs an IV test on the photovoltaic module 6 after the light bathing treatment to obtain electrical performance parameters. The through-track 3 provides a guiding path for the movement of the photovoltaic module 6 between the light bathing device 1 and the solar simulator 2. The mounting bracket 4 supports and fixes the photovoltaic module 6, allowing it to move on the through-track 3. The solar bathing equipment 1 and the solar simulator 2 are connected by a through track 3 and a sliding door 5. The mounting bracket 4 drives the photovoltaic module 6 to move on the track. When the sliding door 5 is opened, the photovoltaic module 6 moves from the solar bathing equipment 1 to the solar simulator 2, or from the solar simulator 2 to the solar bathing equipment 1, thus connecting the solar bathing and IV testing processes.

[0043] This setup, with its through-track 3 and sliding door 5, enables the orderly transfer of photovoltaic modules 6 between the light bath and IV testing areas. This structure avoids the uncertainties of manual handling and reduces the risk of damage to the modules due to human error. Utilizing the guide function of the track and the control of the sliding door 5 ensures precise module movement, improving the continuity and automation of the IV testing process, and facilitating large-scale, efficient IV testing of photovoltaic modules 6.

[0044] It should be noted that the specific configuration of the through-track 3 is not limited here; it can be fixed to the ground where the device is located, or fixed to the bottom of the solar bathing equipment 1 and the solar simulator 2. The specific structure of the solar bathing equipment 1 and the solar simulator 2 is also not limited, as long as it can meet the requirements for solar bathing and IV testing of the photovoltaic modules 6. In a preferred embodiment, the solar bathing equipment 1 includes a first housing 11, a first light box 12, and a first control unit 13. The first light box 12 is located on one side of the first housing 11 and communicates with the first housing 11, facing the mounting bracket 4. The first control unit 13 is connected to the side wall of the first housing 11 and is electrically connected to the first light box 12. Specifically, the first housing 11 constitutes the physical space for solar bathing treatment; the first light box 12 emits specific light to perform solar bathing treatment on the photovoltaic modules 6; the first control unit 13 controls the light parameters (intensity, duration, etc.) of the first light box 12 and maintains a stable environment inside the housing. The solar simulator 2 includes a second enclosure 21, a second lamp box 22, and a second control unit 23. The second lamp box 22 is located on one side of the second enclosure 21 and communicates with it, facing the mounting bracket 4. The second control unit 23 is connected to the side wall of the second enclosure 21 and is electrically connected to the second lamp box 22. The second enclosure 21 constitutes the physical space for IV testing; the second lamp box 22 provides standard illumination for IV testing of the photovoltaic module 6; the second control unit 23 controls the illumination parameters of the second lamp box 22, monitors and adjusts the IV testing environment parameters in real time, and ensures that the IV testing environment meets the corresponding standards.

[0045] With this setup, the solar bathing equipment 1 and the solar simulator 2 each have their own independent enclosures, lamp boxes, and control units, avoiding mutual interference between the lighting systems. The first control unit 13 and the second control unit 23 can precisely adjust the lighting parameters. For example, during solar bathing, the first lamp box 12 can use high-intensity light to accelerate component stabilization, while during IV testing, the second lamp box 22 provides a standard spectrum. This ensures precise and controllable lighting conditions for both solar bathing and IV testing, improving the accuracy and reliability of IV test results, and enabling both solar bathing and IV testing to achieve optimal results, meeting the stringent requirements for photovoltaic module 6 production and quality inspection.

[0046] It should be noted that the specific structure of the mounting bracket 4 is not limited here. In an optional scenario, the mounting bracket 4 is a single shared bracket. In this case, the photovoltaic module 6 is fixed to the mounting bracket 4 during the light bathing and IV testing, and the photovoltaic module 6 and the mounting bracket 4 move together on the through-track 3 (not shown in the figure). The mounting assembly includes rollers, a frame, and a locking mechanism. The rollers are located at the bottom of the frame, and the locking mechanism is located around the perimeter of the frame. The rollers are slidably connected to the through-track 3, and the locking mechanism secures the photovoltaic module 6. The mounting bracket 4 drives the photovoltaic module 6 through the sliding door 5 and moves it on the through-track 3. Specifically, the mounting bracket 4, as a single shared bracket, moves the frame and the photovoltaic module 6 fixed on it by sliding on the through-track 3 via rollers, realizing the transfer of the module between the light bathing equipment 1 and the solar simulator 2. This setup reduces movement resistance through the cooperation of the rollers and the through-track 3, and the locking mechanism ensures the stability of the photovoltaic module 6. The single shared bracket simplifies the operation process, eliminating the need to change brackets between the light bathing and IV testing areas. This design improves component transfer efficiency and reduces the risk of component damage caused by frequent bracket changes. For example, in continuous production IV testing, the bracket can quickly move between the photobath and IV testing areas, ensuring a smooth IV testing process. At the same time, the secure locking mechanism ensures the safety of the component during movement, improving overall IV testing efficiency and component yield.

[0047] In another alternative configuration, the mounting bracket 4 comprises a first bracket 41 and a second bracket 42, in which case the photovoltaic module 6 can slide between the first bracket 41 and the second bracket. The first bracket 41 is located inside the first housing 11 and above the through-track 3, and the second bracket 42 is located inside the second housing 21 and above the through-track 3. The photovoltaic module 6 is slidably connected to the first bracket 41, the second bracket 42, and the through-track 3. Specifically, during light bathing, the photovoltaic module 6 is slidably connected to the first bracket 41 and receives light bathing treatment within the first housing 11; after light bathing, the module slides along the through-track 3 to the second bracket 42 and is slidably connected to the second bracket 42 for IV testing. This configuration, with the first bracket 41 and the second bracket 42 separate, allows for more targeted support of the module in the light bathing and IV testing areas. The first bracket 41 can be designed for the light and heat dissipation environment of the light bathing, while the second bracket 42 can be designed for the precise temperature control environment of the IV testing, avoiding the adaptability issues of a single bracket in different environments. For example, the first support 41 can be made of high-temperature resistant material to accommodate heat accumulation during solar bathing; the second support 42 can work with the temperature control system of the solar simulator 2 to ensure that the components are tested under stable temperature conditions. This design improves the efficiency and stability of solar bathing and IV testing, facilitates targeted maintenance of supports in different areas, extends the service life of the supports, and reduces interference from different functions on the supports, making the solar bathing and IV testing process more professional and efficient.

[0048] It should be noted that the specific installation method of the through-track 3 is not limited here. It can be fixed to the ground where the IV testing device is installed, or the through-track 3 can be fixed to the bottom of the solar bathing equipment 1 and the solar simulator 2. The specific structure of the through-track 3 is also not limited, as long as it allows the mounting bracket 4 or the photovoltaic module 6 to slide on the through-track 3, thus enabling the positional movement of the photovoltaic module 6. In a preferred embodiment, the through-track 3 includes a guide rail and a limiting groove. The limiting groove is fixedly connected to the track and is set along the length of the track. Specifically, the guide rail provides a sliding path for the rollers of the mounting bracket 4 or the rollers set at the bottom of the photovoltaic module 6 during IV testing, guiding the movement of the photovoltaic module 6; the limiting groove is fixed on the guide rail and set along the length of the guide rail, limiting the lateral displacement of the mounting bracket 4 or the photovoltaic module 6, preventing it from deviating from the track during movement.

[0049] This design restricts the lateral movement of the bracket, ensuring that the mounting bracket 4 or photovoltaic module 6 can only slide longitudinally along the guide rail, thus guaranteeing the accuracy of the photovoltaic module 6's movement trajectory. For example, during the light bathing and IV testing processes, the photovoltaic module 6 accurately reaches the preset position each time: in the optimal illumination area of ​​the first light box 12 during light bathing, and in the standard IV testing position of the second light box 22 during IV testing. This design improves the repeatability and reliability of IV test results, reduces IV test errors caused by positional deviations, meets the stringent positional accuracy requirements of the photovoltaic module 6 IV test, and ensures the consistency and accuracy of the IV test data.

[0050] In a preferred embodiment, the sliding door 5 is a pneumatic door, comprising a door body and a drive cylinder. The door body is vertically positioned above the through-track 3, and the drive cylinder is connected to either the first control unit 13 or the second control unit 23. Specifically, the sliding door 5 opens or closes via the drive cylinder, controlling the connection between the solar bathing equipment 1 and the solar simulator 2, thereby controlling the environmental (such as light and temperature) interaction between the areas.

[0051] With this setup, the drive cylinder responds to signals from the control unit, rapidly executing the opening and closing actions of the doors. For example, before the solar bath begins, the drive cylinder closes the sliding door 5 to prevent light leakage from affecting the solar simulator 2 area; after the solar bath ends, the drive cylinder opens the sliding door 5 to facilitate component transfer. This design enhances the automation level of the device, reduces the risk of manual operation, and avoids environmental interference caused by human error. Simultaneously, the rapid opening and closing action improves operational convenience and efficiency, providing reliable support for the automated control of the entire IV testing device and ensuring environmental stability and smooth workflow during the solar bath and IV testing processes.

[0052] In a preferred embodiment, the first control unit 13 includes a first control cabinet 131 and a first fan 132. The first light box 12 is electrically connected to the first control cabinet 131, and the first fan 132 is also electrically connected to the first control cabinet 131. The first fan 132 is located on top of the first enclosure 11, above the through-track 3. Specifically, the first control unit 13 coordinates and controls the first light box 12 and the first fan 132 through the first control cabinet 131. During light bathing, the first control cabinet 131 adjusts parameters such as the light intensity and duration of the first light box 12, and simultaneously controls the operation of the first fan 132 based on the temperature feedback inside the first enclosure 11 to dissipate heat in a timely manner and maintain a stable light bathing environment.

[0053] With this setup, the first control cabinet 131 precisely adjusts the first lamp box 12 according to the light bathing requirements, while the first fan 132 dissipates heat, preventing excessive temperature inside the first enclosure 11 during the light bathing process. For example, during prolonged light bathing, the first fan 132 operates continuously to ensure the temperature of the first enclosure 11 remains within the tolerance range of the photovoltaic module 6, preventing excessive temperature from affecting the performance of the photovoltaic module 6 or damaging the equipment. This design improves the consistency of the light bathing effect, ensures the stability of the light bathing process, extends the service life of the first lamp box 12 and related equipment, and enables the light bathing equipment 1 to operate stably for a long time, providing a reliable guarantee for the light bathing treatment of the photovoltaic module 6.

[0054] In a preferred embodiment, the second control unit 23 includes a second control cabinet 231, a third control cabinet 232, a second fan 233, and a temperature controller 234. The second control cabinet 231 is electrically connected to the second light box 22, the third control cabinet 232 is electrically connected to the second fan 233, and the third control cabinet 232 is electrically connected to the temperature controller 234. The second fan 233 is located on the top of the second enclosure 21, and the temperature controller 234 is fixedly connected to the side wall of the second enclosure 21. Specifically, the second control unit 23, through the coordinated operation of the second control cabinet 231, the third control cabinet 232, the second fan 233, and the temperature controller 234, controls the illumination parameters of the second light box 22 and simultaneously adjusts the temperature inside the second enclosure 21. During IV testing, the second control cabinet 231 ensures that the second light box 22 provides standard illumination, and the third control cabinet 232, based on feedback from the temperature sensor, controls the second fan 233 and the temperature controller 234 to maintain a constant temperature within the enclosure.

[0055] This setup enables precise control of the IV testing environment through multi-component collaboration. The second control cabinet 231 ensures that the illumination meets IV testing standards, while the third control cabinet 232 coordinates the second fan 233 and the temperature controller 234 to handle temperature fluctuations. For example, when the IV testing environment temperature rises, the temperature controller 234 activates cooling, and the second fan 233 assists in heat dissipation to ensure temperature stability. This design meets the stringent requirements of IV testing for illumination and temperature, improves the accuracy and reliability of IV test data, and ensures that the IV test results truly reflect the electrical performance of the photovoltaic module 6, providing a reliable basis for module quality assessment and classification.

[0056] It should be noted that the temperature controller 234 here can be a cooling or heating device, or a combination of both, as long as it can adjust the temperature according to the IV test temperature requirements.

[0057] In a preferred embodiment, an electric door 7 is provided between the second light box 22 and the second enclosure 21, and the second control cabinet 231 is electrically connected to the electric door 7. Specifically, the second control cabinet 231 controls the opening and closing of the electric door 7 to facilitate maintenance of the second light box 22 or to maintain the internal sealing of the second enclosure 21 during IV testing. The electric door 7 is opened for maintenance and closed for IV testing. Through this setting, the second control cabinet 231 precisely controls the timing of opening and closing the electric door 7. For example, when periodically maintaining the second light box 22, the electric door 7 is opened, allowing operators to safely approach the light box; after maintenance, the electric door 7 is closed, and the second enclosure 21 quickly returns to a sealed IV testing environment, preventing external interference. This design improves the maintainability of the internal equipment of the solar simulator 2, reduces the impact of maintenance on the IV testing process, and ensures the continuity and accuracy of IV testing. It avoids environmental fluctuations caused by frequent opening of the enclosure, ensuring that each IV test is conducted in a stable environment, thus improving the reliability and consistency of IV test results.

[0058] In a preferred embodiment, the photovoltaic module IV testing device also includes a communication interface, which is integrated on the solar bathing equipment 1 and / or the solar simulator 2. The communication interface is connected to the solar bathing equipment 1 and to the solar simulator 2. Specifically, the communication interface transmits data (such as illumination parameters, temperature, module electrical performance, etc.) from the solar bathing equipment 1 and the solar simulator 2 during operation to external devices in real time, and simultaneously receives control commands from external devices to achieve coordinated control and data sharing of the equipment.

[0059] With this setup, light bath and IV test data can be uploaded to a computer for analysis in real time via a communication interface, and external commands can remotely control equipment parameters. For example, on an automated production line, a host computer can monitor multiple IV testing devices uniformly through the communication interface, adjusting light parameters and initiating IV testing processes. This design enhances the intelligence of the device, facilitates data storage, analysis, and traceability, and provides data support for the production quality control of photovoltaic modules. Simultaneously, it lays the foundation for linkage with other production equipment, promoting the intelligent and integrated development of the photovoltaic IV testing industry, improving production efficiency and management levels, and meeting the needs of large-scale, high-precision production in the modern photovoltaic industry.
