[0019] A high stability test method for photovoltaic modules, using the high stability test system for photovoltaic modules, comprises the following steps:

[0020] S1. Initially, the second inspection platform is located near the box door, the heating component is located above the first inspection platform, and the air cooling component is located above the second inspection platform. When working, the photovoltaic component to be inspected is placed on the second inspection platform, and then the drive motor is started. The drive motor drives the sprocket to rotate clockwise through its output shaft, so that the chain is driven clockwise. During the clockwise transmission of the chain, the two connecting members on the lower side drive the bottom plate to move left, and on the contrary, the two connecting members on the upper side drive the first inspection platform to move right through the fixing bar, that is, the first inspection platform and the second inspection platform can move in opposite directions;

[0021] S2. During the process of the bottom plate moving to the left, the bottom plate drives the roller to slide on the inner side of the guide groove through the connecting shaft, so that the bottom plate moves in the process of translation, downward movement, translation, upward movement, and translation. During this process, the bottom plate can drive the second inspection platform to move up and down through the column, and the first inspection platform is always in a state of equal-height translation under the guide limit of the slide seat and the guide rod. This makes it possible for the second inspection platform to pass from the lower side of the first inspection platform during the process of the second inspection platform moving in the opposite direction to the first inspection platform, so that the second inspection platform and the first inspection platform slide staggered and the second inspection platform and the first inspection platform are interchanged in position;

[0022] S3, then, turn on the power supply, turn on the electric heating rod, and heat the photovoltaic module on the second testing platform below it through the electric heating rod, so that the temperature of the photovoltaic module gradually increases, so as to detect the heat resistance of the photovoltaic module under high temperature. At this time, the first testing platform is located below the air-cooled component. At this time, the second photovoltaic module to be tested can be installed on the first testing platform, waiting for the next high temperature resistance test;

[0023] S4. After the high temperature resistance test of the first photovoltaic component is completed, the driving motor drives the sprocket to reverse through its output shaft, so that the chain rotates counterclockwise, so that the second test platform and the first test platform are interchanged again and return to the initial position. At this time, the second photovoltaic component to be tested on the first test platform is located below the heating component, and is heated to a high temperature by the heating component, and the first photovoltaic component returns to the bottom of the air cooling component with the second test platform. At this time, the first photovoltaic component in a high temperature state is not convenient to disassemble, and the setting of the air cooling component can connect the air duct with the external air conditioner, and inject cold air into the inside of the hollow frame through the air conditioner and the air duct, and the cold air inside the hollow frame is discharged through the blow pipe to cool down the first photovoltaic component on the second test platform. At this time, the cooled first photovoltaic component can be disassembled and the third photovoltaic component to be tested can be installed on the second test platform, or the first photovoltaic component can be continuously cooled to test the performance of the photovoltaic component in a low temperature state;

[0024] S5. The partition can be set to block the space corresponding to the cooling and heating inside the outer box to a certain extent, and in the process of moving the first detection platform, the partition can be pushed and pulled by the connecting rod. In the process of the first detection platform and the second detection platform approaching each other, the connecting rod pushes up the partition, so that the partition does not hinder the translation of the first detection platform. In the process of the first detection platform and the second detection platform moving away from each other after being staggered, the partition gradually moves down to block the space corresponding to the cooling and heating inside the outer box again.

[0025] The working principle and beneficial effects of the present invention are:

[0026] 1. In the present invention, two second guide mechanisms are symmetrically arranged inside the outer box, a first detection platform and a second detection platform for placing the photovoltaic components to be tested are arranged between the two second guide mechanisms, and a first guide mechanism is arranged between the two second guide mechanisms for supporting the second detection platform to move in and out. A driving mechanism is arranged inside the outer box, and the driving mechanism includes a driving motor and two driving components, the two driving components are respectively located on one side of the second guide mechanism, and while the driving motor drives the driving components, the driving components can be used to stagger the first detection platform and the second detection platform to slide, so that the first detection platform and the second detection platform can be interchanged, and while a photovoltaic component is being tested at high temperature, the next photovoltaic component can be pre-installed, thereby avoiding the time spent on disassembling the photovoltaic panels under high temperature, significantly improving work efficiency, and improving safety performance;

[0027] 2. In the present invention, a partition is provided on the sliding sleeve at the top of the outer box. The partition can be provided to block the space corresponding to the cooling and heating inside the outer box to a certain extent, and the partition can be pushed and pulled by the connecting rod during the movement of the first detection platform. During the movement of the first detection platform and the second detection platform approaching each other, the connecting rod pushes up the partition so that the partition will not block the translation of the first detection platform. During the process of the first detection platform and the second detection platform moving away from each other after being staggered, the partition gradually moves down to block the space corresponding to the cooling and heating inside the outer box again, thereby improving the stability of the detection environment.

[0028] 3. In the present invention, a heating component for heating the photovoltaic component to be tested and an air-cooling component for cooling the photovoltaic component to be tested are respectively arranged in the spaces corresponding to the cooling and heating. The heating component and the air-cooling component correspond to the first detection platform and the second detection platform respectively. A photovoltaic component is heated at a high temperature by the heating component, and after the heating detection, the photovoltaic component is moved under the air-cooling component. At this time, the photovoltaic component in a high temperature state is not convenient to disassemble. The setting of the air-cooling component can connect the air duct with the external air conditioner, and inject cold air into the inner side of the hollow frame through the air conditioner and the air duct. The cold air inside the hollow frame is discharged through the blow pipe to cool down the photovoltaic components on the second detection platform. At this time, the cooled photovoltaic components can be disassembled and other photovoltaic components to be detected can be installed on the detection platform. Alternatively, the photovoltaic components can be continuously cooled to detect the performance of the photovoltaic components in a low temperature state. The photovoltaic components have good applicability. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, a partition 3 is provided on the top sliding sleeve of the outer box 1, and the interior of the outer box 1 is divided into two spaces by the partition 3.

[0063] Working principle and usage process: Initially, the second inspection platform 9 is located on the side close to the box door 12, the heating component 4 is located above the first inspection platform 8, and the air cooling component 5 is located above the second inspection platform 9. During operation, the photovoltaic component to be inspected is placed on the second inspection platform 91. Then, the drive motor 21 is started. The drive motor 21 drives the sprocket 22 to rotate clockwise through its output shaft, so that the chain 23 is driven clockwise. During the clockwise transmission of the chain 23, the two connecting parts 24 on the lower side drive the bottom plate 95 to move left. On the contrary, the two connecting parts 24 on the upper side drive the first inspection platform 83 to move right through the fixing bar 81, that is, the first inspection platform 83 and the second inspection platform 91 can move in opposite directions.

[0064] During the process of the bottom plate 95 moving to the left, the bottom plate 95 drives the roller 97 to slide on the inner side of the guide groove 74 through the connecting shaft 96, so that the bottom plate 95 moves in a sequence of translation, downward movement, translation, upward movement, and translation.

This makes it possible for the second inspection platform 91 to pass through the lower side of the first inspection platform 83 when the second inspection platform 91 moves in the opposite direction to the first inspection platform 83, so that the second inspection platform 91 and the first inspection platform 83 slide staggered and the second inspection platform 91 and the first inspection platform 83 are interchanged. Afterwards, when conducting a temperature characteristic test to understand the performance of the photovoltaic module at different temperatures, after placing the photovoltaic module on the test bench, electrically connect the data line of the current and voltage detector or other suitable testing equipment to the photovoltaic module to be tested, turn on the power, turn on the electric heating rod 44, and heat the photovoltaic module on the second test bench 91 located below it through the electric heating rod 44, so that the temperature of the photovoltaic module gradually increases, so as to detect the heat resistance of the photovoltaic module at high temperature. At this time, the first test bench 83 is located below the air-cooled component 5. At this time, the second photovoltaic module to be tested can be installed on the first test bench 83, waiting for the next high temperature resistance test.

[0065] After the high temperature resistance test of the first photovoltaic component is completed, the driving motor 21 drives the sprocket 22 to reverse through its output shaft, so that the chain 23 rotates counterclockwise, so that the second test platform 91 and the first test platform 83 are interchanged again and return to the initial position. At this time, the second photovoltaic component to be tested on the first test platform 83 is located below the heating component 4, and is heated at high temperature by the heating component 4, and the first photovoltaic component returns to the bottom of the air cooling component 5 with the second test platform 91. At this time, the first photovoltaic component in a high temperature state is not convenient to disassemble, and the setting of the air cooling component 5 can connect the air duct 51 with the external air conditioner, and inject cold air into the inside of the hollow frame 52 through the air conditioner and the air duct 51. The cold air inside the hollow frame 52 is discharged through the blow pipe 53 to cool down the first photovoltaic component on the second test platform 91. At this time, the first photovoltaic component after cooling can be disassembled, and the third photovoltaic component to be tested can be installed on the second test platform 91, or the first photovoltaic component can be continuously cooled to detect the performance of the photovoltaic component in a low temperature state.

[0066] The setting of the partition 3 can block the space corresponding to the cooling and heating inside the outer box 1 to a certain extent, and in the process of moving the first detection platform 83, the partition 3 can be pushed and pulled by the connecting rod 84. In the process of the first detection platform 8 and the second detection platform 9 approaching each other, the connecting rod 84 pushes up the partition 3, so that the partition 3 will not hinder the translation of the first detection platform 83. In the process of the first detection platform 8 and the second detection platform 9 moving away from each other after being staggered, the partition 3 gradually moves down to block the space corresponding to the cooling and heating inside the outer box 1 again.

Initially, the second inspection platform (9) is located on the side close to the box door (12), the heating component (4) is located above the first inspection platform (8), and the air cooling component (5) is located above the second inspection platform (9). During operation, the photovoltaic component to be inspected is placed on the second inspection platform (91). Then, the drive motor (21) is started. The drive motor (21) drives the sprocket (22) to rotate clockwise through its output shaft, so that the chain (23) is driven clockwise. During the clockwise transmission of the chain (23), the two connecting members (24) located on the lower side drive the bottom plate (95) to move leftward. On the contrary, the two connecting members (24) located on the upper side drive the first inspection platform (83) to move rightward through the fixing bar (81), that is, the first inspection platform (83) and the second inspection platform (91) can move in opposite directions. S2. During the process of the bottom plate (95) moving to the left, the bottom plate (95) drives the roller (97) to slide on the inner side of the guide groove (74) through the connecting shaft (96), so that the bottom plate (95) moves in the process of translation, downward movement, translation, upward movement, and translation.

This makes it possible for the second inspection platform (91) to pass through the lower side of the first inspection platform (83) during the process of the second inspection platform (91) moving in the opposite direction to the first inspection platform (83), so that the second inspection platform (91) and the first inspection platform (83) slide staggered, and the second inspection platform (91) and the first inspection platform (83) are interchanged in position; S3, then, the power supply is turned on, the electric heating rod (44) is turned on, and the temperature of the photovoltaic module on the second testing platform (91) located below the electric heating rod (44) is heated, so that the temperature of the photovoltaic module gradually increases, so as to detect the heat resistance performance of the photovoltaic module under high temperature. At this time, the first testing platform (83) is located below the air cooling component (5). At this time, the second photovoltaic module to be tested can be installed on the first testing platform (83) to wait for the next high temperature resistance test; S4. After the high temperature resistance test of the first photovoltaic module is completed, the driving motor (21) drives the sprocket (22) to reverse through its output shaft, so that the chain (23) rotates counterclockwise, so that the second testing platform (91) and the first testing platform (83) are interchanged again and return to the initial position. At this time, the second photovoltaic module to be tested on the first testing platform (83) is located below the heating component (4) and is heated to a high temperature by the heating component (4). The first photovoltaic module returns to the bottom of the air cooling component (5) along with the second testing platform (91). At this time, the first photovoltaic module in a high temperature state It is not convenient to disassemble, but the air cooling component (5) is set up so that the air duct (51) can be connected to an external air cooler, and cold air is injected into the inside of the hollow frame (52) through the air cooler and the air duct (51), and the cold air inside the hollow frame (52) is discharged through the blower pipe (53) to cool down the first photovoltaic component on the second testing platform (91).
