[0040] Working principle: When the present invention is in use, when the solar panel is transported by the conveyor belt 110, the solar panel collides with the alignment plate 321. When the solar panel contacts the inclined surface of the alignment plate 321, the solar panel can be aligned and transported. When the solar panel collides with the alignment plate 321, the alignment plate 321 is driven to move in the direction close to the connecting seat 311, and then the horizontal plate end of the trigger plate 324 is in conflict with the inclined surface of the guide block 333, thereby driving the guide block 333 and the locking block 334 to move downward, so that the locking block 334 is separated from the support plate 122, thereby canceling the lock of the shift plate 310, and then the solar panel continues to move, thereby pushing the shift plate 310 to move along the guide rod 123 in the direction close to the support plate 121, thereby driving the connecting rod 340 to move, and then driving the carrying plate 510 and the trigger rod 530 to move, the trigger rod 530 is in conflict with the inclined section of the guide frame 130, thereby driving the trigger rod 530 to move upward, and then driving the carrying plate 510 and the wiring The post 540 moves upward, and the terminal post 540 passes through the conveyor belt 110 and contacts the electrode of the solar panel, so that the solar panel is connected to the multimeter, and the solar panel is moved to the first detection chamber 120. After a certain period of illumination, the change in the indication of the multimeter is recorded to test the energy conversion efficiency of the solar panel. After the test of the solar panel in the first detection chamber 120 is completed, the conveyor belt 110 drives the solar panel to move to the second detection chamber 120, and then the guide rod 314 contacts the inclined surface of the guide plate 124, thereby driving the connecting seat 311 and the aligning plate 321 to move upward, thereby avoiding the transportation of the solar panel, and then the elastic force of the spring 1 pushes the shift plate 310 to reset. During the reset process of the shift plate 310, the trigger rod 530 rotates clockwise around the connecting shaft 552, and the elastic force of the spring 5 pushes the bearing plate 510 and the terminal post 540 to move downward, and the solar panel is moved to the second detection chamber 120 for testing, thereby performing the test in sequence.

In the initial state, the end of the rack contacts the support plate 4. The trigger rod is arranged vertically, and the upper end of the trigger rod is connected to the connecting shaft.

8. A solar panel performance testing device according to claim 7, characterized in that: A guide frame is arranged on the base, and the guide frame includes a vertical section, a horizontal section, and an inclined section. The inclined section of the guide frame is located between the vertical section and the horizontal section of the guide frame. In the initial state, the bottom of the trigger rod contacts the inclined section of the guide frame.

9. A solar panel performance testing device according to claim 8, characterized in that: A guide plate is arranged below the top surface of the detection chamber, the guide plate is close to the conveyor belt and away from the connecting seat, a guide rod is arranged horizontally at the side wall of the connecting seat, and the guide plate is arranged obliquely near the side of the connecting seat.

10. A method for testing a solar panel performance testing device according to claim 9, wherein: S1. When the solar panel is transported by the conveyor belt, the solar panel collides with the alignment plate. When the solar panel contacts the inclined surface of the alignment plate, the solar panel can be aligned and transported. When the solar panel collides with the alignment plate, the alignment plate is driven to move toward the connecting seat, and then the horizontal plate end of the trigger plate collides with the inclined surface of the guide block, thereby driving the guide block and the locking block to move downward, so that the locking block is separated from the support plate, thereby canceling the lock on the shift plate; S2. Then the solar panel continues to move, thereby pushing the shift plate to move along the guide rod 1 toward the direction close to the support plate 1, thereby driving the connecting rod to move, and then driving the bearing plate and the trigger rod to move, the trigger rod contacts the inclined section of the guide frame, thereby driving the trigger rod to move upward, and then driving the bearing plate and the terminal to move upward, the terminal passes through the conveyor belt and contacts the electrode of the solar panel, so that the solar panel is connected to the multimeter, and the solar panel is moved to the first detection room, after being illuminated, the change in the reading of the multimeter is recorded, so as to test the energy conversion efficiency of the solar panel; S3. After the solar panel is tested in the first inspection room, the conveyor belt drives the solar panel to move into the second inspection room, and then the guide rod contacts the inclined surface of the guide plate, thereby driving the connecting seat and the alignment plate to move up, thereby avoiding the transportation of the solar panel, and then the elastic force of the spring 1 pushes the shift plate to reset. During the resetting process of the shift plate, the trigger rod rotates clockwise around the connecting axis, and the elastic force of the spring 5 pushes the bearing plate and the terminal to move down, and the solar panel is moved to the second inspection room for testing, and then the tests are carried out in sequence.
