[0002] Perovskite photovoltaic modules are a new type of photovoltaic module with perovskite structural materials as the core. The core materials have excellent photoelectric properties, such as high light absorption coefficient, long carrier diffusion distance and mobility, which can significantly improve photoelectric conversion efficiency.

[0003] In existing technologies, after perovskite photovoltaic modules are manufactured, the flatness of the product needs to be tested to ensure the flatness of subsequent installation. However, this often requires workers to manually observe the flatness with their eyes, which is not only labor-intensive, but also makes it impossible to detect minor warping in time, affecting product quality.

The bottom end of each limiting slide plate is fixed with a movable plate.

[0011] Preferably, the bottom of the lower pressure plate is provided with four scale lines in a cross shape, and the four scale lines are respectively located on one side of the four strip-shaped through holes, and the scale lines are arranged parallel to the corresponding strip-shaped through holes.

[0012] Preferably, the inspection component includes four pressure sensors, the tops of which are respectively fixed to the bottoms of four movable plates, and the bottoms of which can respectively abut against the tops of the four ends of the perovskite photovoltaic module.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-5 The present invention provides an inspection device for perovskite photovoltaic modules, used to inspect the flatness of perovskite photovoltaic modules 1. It includes a base plate 2, a support plate 3 vertically fixed to the rear top of the base plate 2, a top plate 4 longitudinally fixed to the top of the support plate 3, a lower pressure plate 5 fixed to the top plate 4 by a lifting component, an inspection component fixed to the lower pressure plate 5 by an adjustment component, and a clamping component for positioning the perovskite photovoltaic module 1 fixed to the top of the base plate 2.

[0023] The lifting assembly includes a vertically arranged first electric push rod 6. The bottom of the first electric push rod 6 is fixed to the top of the top plate 4. The output shaft of the first electric push rod 6 vertically penetrates the top plate 4, and a connecting plate 7 is fixed to the bottom of the output shaft of the first electric push rod 6. The bottom of the connecting plate 7 is fixed to the center of the top of the lower pressure plate 5. Specifically, when the first electric push rod 6 is running, it can drive the lower pressure plate 5 to move up and down through the connecting plate 7.

[0024] The adjustment assembly includes four movable bases 8, which are fixed in a cross shape to the top of the lower pressure plate 5. A servo motor 9 is fixed to the end of each movable base 8, and a lead screw 10 is fixed to the output shaft of each servo motor 9. A threaded sleeve 11 is threaded onto the surface of each lead screw 10. A strip-shaped limiting hole 12 is provided at the bottom of each movable base 8. Four strip-shaped through holes 13 are provided in a cross shape on the lower pressure plate 5. The four strip-shaped through holes 13 and the four strip-shaped limiting holes 12 are connected vertically to each other. A limiting slide plate is vertically fixed to the bottom of each threaded sleeve 11. 14. The bottom end of the limiting slide plate 14 passes through the strip-shaped limiting hole 12 and the strip-shaped through hole 13 in sequence, and the surface of the limiting slide plate 14 is in contact with the wall of the strip-shaped limiting hole 12. The bottom end of the limiting slide plate 14 is fixed with a moving plate 15. Specifically, under the combined limiting action of the limiting slide plate 14 and the strip-shaped limiting hole 12, when the servo motor 9 drives the lead screw 10 to rotate in the forward and reverse directions, the threaded sleeve 11 threaded to the surface of the lead screw 10 can move back and forth in a straight line, so that the corresponding moving plate 15 can be driven to move back and forth in a straight line through the limiting slide plate 14.

[0025] The bottom of the pressure plate 5 is provided with four scale lines 16 in a cross shape. The four scale lines 16 are located on one side of the four strip-shaped through holes 13. The scale lines 16 are parallel to the corresponding strip-shaped through holes 13. Specifically, the scale lines 16 can help the operator to adjust the moving plate 15 to the required position.

[0026] The inspection assembly includes four pressure sensors 17. The tops of the four pressure sensors 17 are respectively fixed to the bottoms of four movable plates 15. The bottoms of the four pressure sensors 17 can respectively abut against the tops of the four ends of the perovskite photovoltaic module 1. Specifically, when the first electric push rod 6 moves and drives the lower pressure plate 5 to move down, it can drive the movable plate 15 and the pressure sensors 17 to move down synchronously, thereby pressing down on the tops of the four ends of the perovskite photovoltaic module 1 at the same time. At this time, under the action of the four pressure sensors 17, the magnitude of the force can be monitored in real time. By using the difference range of the pressure sensors 17, it can be determined whether the flatness of the perovskite photovoltaic module 1 is qualified. No manual operation is required, which effectively reduces the workload of operators and greatly improves the inspection effect. Even minor warping can be inspected normally, which is conducive to controlling product quality. Moreover, the pressure sensors 17 can be adjusted linearly synchronously with the movable plate 15, which can effectively inspect the flatness of perovskite photovoltaic modules 1 of different sizes.

[0027] The clamping assembly includes four second electric push rods 18, which are fixed in a cross shape to the top of the base plate 2. Each second electric push rod 18 has a clamping plate 19 fixed to its output shaft. Each clamping plate 19 has a rubber pad 20 fixed to its surface. The surfaces of the four rubber pads 20 respectively abut against the sides of the four ends of the perovskite photovoltaic module 1. Specifically, when the second electric push rods 18 are running, they can drive the clamping plates 19 and the rubber pads 20 to move back and forth in a straight line, thereby clamping and fixing the sides of the four ends of perovskite photovoltaic modules 1 of different sizes. Therefore, this device is also well applicable to the flatness inspection of perovskite photovoltaic modules 1 of different sizes. It has a wide range of applications. Under the action of the rubber pads 20, not only can the sides of the four ends of the perovskite photovoltaic module 1 be protected from being damaged by the clamping plates 19, but it can also play a certain deformation buffering role, effectively preventing the perovskite photovoltaic module 1 from being deformed by the clamping plates 19 and affecting the accuracy of the inspection results.

[0028] It should be noted that this device is electrically connected to an external controller and 220V AC mains power. The controller can be an existing control device such as a computer. The controller is electrically connected to a display screen to display the pressure value detected by the pressure sensor 17. In this invention, the precise control principle of the first electric push rod 6 and the second electric push rod 18 is to achieve motion conversion through the mechanical cooperation of a servo motor and a lead screw. The status is monitored in real time with the help of devices such as encoders, and finally the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed and force within the millimeter or even micrometer range.

[0029] The above are merely preferred embodiments of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
