As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0028] The utility model will be described in detail below with the drawings:

[0029] Overall structure of the device:

[0030] The impact test device for the photovoltaic panel mainly consists of a stand 24, a crossbeam 1, a moving seat 2, a lifting arm 5, a containing box 15, a conveying belt 10, a workbench 21 and the like. The crossbeam 1 is supported at both ends by the stand 24 to form a stable frame structure. The moving seat 2 is slidably arranged on the crossbeam 1 and can move left and right on the crossbeam 1. The lifting arm 5 is arranged on the moving seat 2 and can be lifted up and down. The containing box 15 is installed on the lifting arm 5 and used for storing impact balls.

[0031] Impact ball conveying system:

[0032] The stand 24 at one end of the crossbeam 1 is provided with a conveying channel 9, and the conveying channel 9 is provided with a conveying belt 10. The conveying belt 10 is provided with baffles 11 arranged in rows for separating impact balls and ensuring the orderly conveying of the impact balls. The side wall of the conveying channel 9 at the bottom of the conveying belt 10 is provided with an inlet 25, and the side wall of the conveying channel 9 at the top of the conveying belt 10 is provided with an outlet 26. The workbench 21 is arranged between the two stands 24, and the bottom surface of the workbench 21 is inclined. The workbench 21 is provided with an opening matched with the inlet 25, and the opening is provided with a flow guide groove 23. When the impact balls are impacted from the discharge port 18 to the photovoltaic panel on the workbench 21, they will fall into the workbench 21 and then enter the inlet 25 of the conveying channel 9 through the opening along the inclined bottom surface of the workbench 21 and the flow guide groove 23, and then be conveyed to the outlet 26 at the top by the conveying belt 10.

[0033] The other side wall of the conveying channel 9 at the top of the conveying belt 10 is provided with a pneumatic cylinder 12 and a first proximity switch 13, and the piston rod of the pneumatic cylinder 12 is provided with a second proximity switch 14. When it is necessary to add impact balls in the containing box 15, the containing box 15 is controlled to move to the outlet 26 so that the inlet 17 is connected with the outlet 26, and then the conveying belt 10 is controlled to start. When the first proximity switch 13 and the second proximity switch 14 simultaneously detect signals, it indicates that there are impact balls on the baffles 11. At this time, the piston rod of the pneumatic cylinder 12 is extended to push the impact balls into the containing box 15. The filling quantity of the impact balls can be technically controlled by the action of the piston rod of the pneumatic cylinder, and when the preset quantity is reached, the conveying belt 10 stops working.

[0034] Driving structure of the moving seat 2 and the lifting arm 5:

[0035] A first slide rail assembly 3 is mounted on the crossbeam 1, and a movable seat 2 is mounted on the first slide rail assembly 3. A first rack 4 is also mounted on the crossbeam 1, and a first gear meshing with the first rack 4 is mounted on the movable seat 2. The first gear is connected to a first motor. The first motor drives the first gear to rotate. Because the first gear meshes with the first rack 4, the movable seat 2 slides along the first slide rail assembly 3 on the crossbeam 1, enabling testing of different positions on the photovoltaic panel.

[0036] A second rack 7 is provided on the lifting arm 5, and a second gear 8 meshing with the second rack 7 is provided on the movable base 2. The second gear 8 is connected to a second motor. A second slide rail assembly 6 is also provided on the movable base 2, and the lifting arm 5 is mounted on the second slide rail assembly 6. The second motor drives the second gear 8 to rotate, and the second gear 8 cooperates with the second rack 7 to make the lifting arm 5 move up and down along the second slide rail assembly 6 on the movable base 2, realizing impact testing at different heights.

[0037] Impact ball release structure:

[0038] An impact ball channel 16 is provided inside the holding box 15, and impact balls are placed in the impact ball channel 16. One end of the impact ball channel 16 is connected to an inlet 17, which is positioned to match the outlet 26, ensuring that the impact balls exiting the outlet 26 can smoothly enter the impact ball channel 16. The other end of the impact ball channel 16 is connected to an outlet 18, and a rotating shaft 20 connected to a third motor is provided at the outlet 18. A circumferential array of actuating blades 19 is arranged on the rotating shaft 20. When impact testing is required, the third motor drives the rotating shaft 20 to rotate, which in turn drives the actuating blades 19 to rotate, pushing the impact balls out of the outlet 18, thus realizing the impact test on the photovoltaic panel.

[0039] Testing process:

[0040] First, the photovoltaic panel to be tested is placed on the support frame 22 on the workbench 21. The device is started, controlling the movement of the inlet 17 of the holding box 15 to the outlet 26. The impact balls in the workbench 21 are conveyed from the inlet 25 to the outlet 26 via the conveyor belt 10, and then enter the impact ball channel 16 of the holding box 15 through the inlet 17. The moving seat 2 is moved to the designated test position by the first motor, and the lifting arm 5 is raised and lowered to the required impact height by the second motor. Then, the third motor drives the actuating blade 19 to rotate, pushing the impact balls out from the outlet 18 to impact the photovoltaic panel. The impact balls fall back into the workbench 21 after impact, and can be conveyed again when the impact balls in the holding box 15 need to be replenished.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
