DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] See also Figures 1 to 4 The present invention provides a photovoltaic panel 19 flatness detection device, comprising:

[0033] The frame 1 has a first direction and a second direction, and a detection position 2 for placing a photovoltaic panel 19 is provided along the first direction of the frame 1;

[0034] A detection assembly, the detection assembly comprising a detection wheel 3 and an indicator pen 4 connected to each other, the detection wheel 3 being suspended from the detection position 2, the writing end of the indicator pen 4 being arranged close to the second direction, and a writing paper 5 in contact with the writing end of the indicator pen 4 being arranged in the second direction;

[0035] A moving rod 6 is slidably disposed on the frame 1 along the first direction, and the detection wheel 3 is movably disposed on the moving rod 6;

[0036] A walking assembly, slidably disposed on the moving rod 6 along the second direction;

[0037] Wherein, the first direction and the second direction are arranged perpendicular to each other.

[0038] In this embodiment, the frame 1 serves as the main structure of the entire detection device, provides a detection position 2 for placing the photovoltaic panel 19, and defines two mutually perpendicular directions (a first direction and a second direction. In this embodiment, the first direction and the second direction are the length direction and the width direction of the frame 1, respectively), ensuring accurate positioning during the detection process. The detection component is composed of a detection wheel 3 and an indicator pen 4. The detection wheel 3 is in rolling contact with the surface of the photovoltaic panel 19 and can move up and down with the unevenness of the surface of the photovoltaic panel 19. The indicator pen 4 is arranged on the detection wheel 3, and its writing end is in contact with the writing paper 5. When the detection wheel 3 moves, the indicator pen 4 will draw a corresponding track on the white paper, reflecting the unevenness of the surface of the photovoltaic panel 19. On the other hand, the moving rod 6 is installed on the frame 1 along the first direction, allowing the detection wheel 3 to slide thereon, and the detection wheel 3 can move along one side length direction of the photovoltaic panel 19, thereby increasing the detection range and flexibility; on the other hand, the walking assembly is installed on the moving rod 6, which can slide in the second direction, so that the detection wheel 3 can move not only in the first direction but also in the second direction, thereby realizing a comprehensive detection of the surface of the photovoltaic panel 19. According to the size of the photovoltaic panel 19, the present invention can be very flexibly adapted to photovoltaic panels 19 of different sizes. Through the moving track left by the indicating pen 4 on the writing paper 5, the flatness of the surface of the photovoltaic panel 19 can be intuitively seen, which is convenient for subsequent analysis and processing. In addition, this detection method is non-destructive and will not cause any damage to the photovoltaic panel 19.

[0039] A connecting column 7 is provided between the detection wheel 3 and the indicating pen 4 . The connecting column 7 is sleeved on a spring 8 . Two ends of the spring 8 are respectively in contact with the connecting column 7 and the detection wheel 3 .

[0040] In this embodiment, the connecting column 7 connects the detection wheel 3 and the indicator pen 4, not only plays a role of physical connection, but also carries a spring 8 to achieve elastic connection. The spring 8 is sleeved on the connecting column 7, and its two ends are respectively in contact with the connecting column 7 and the detection wheel 3. The main function of the spring 8 is to provide a certain elastic force, so that the detection wheel 3 can move up and down with the slight undulations on the surface of the photovoltaic panel 19, while maintaining sufficient pressure to ensure that the indicator pen 4 can stably leave a clear track on the white paper. The existence of the spring 8 enables the detection wheel 3 to respond more sensitively to the slight unevenness of the surface of the photovoltaic panel 19, even a small protrusion 901 or depression can be accurately recorded, and the elastic force of the spring 8 can ensure that the detection wheel 3 always contacts the surface of the photovoltaic panel 19 with appropriate pressure, avoiding inaccurate detection results due to excessive or insufficient pressure; due to the buffering effect of the spring 8, the detection wheel 3 will not produce false detection due to hard collision when encountering a larger protrusion, thereby improving the accuracy and reliability of the detection.

[0041] The frame 1 is provided with a slide groove 101 , and the moving rod 6 is slidably disposed in the slide groove 101 .

[0042] In this embodiment, a slide groove 101 is arranged on the frame 1, and the slide groove 101 extends along the first direction, providing a fixed track for the moving rod 6. The moving rod 6 is installed in the slide groove 101 and can slide in the first direction in the slide groove 101. The design of the slide groove 101 ensures that the movement trajectory of the moving rod 6 is straight and smooth, which is convenient for flatness detection of the surface of the photovoltaic panel 19 in the length direction.

[0043] The walking assembly is a first telescopic rod 10 disposed between the connecting column 7 and the indicating pen 4 . The first telescopic rod 10 is used to drive the detection wheel 3 to slide back and forth on the moving rod 6 along the second direction.

[0044] In this embodiment, the walking assembly is in the form of a telescopic rod, and the two ends of the telescopic rod are respectively connected to the connecting column 7 of the detection wheel 3 and the indicating pen 4. After the detection wheel 3 slides from front to back along the first direction, the telescopic rod drives the detection wheel 3 to slide along the second direction, and the indicating pen 4 is always in contact with the writing paper 5. The sliding distance of the detection wheel 3 is the distance of the wheel width of the detection wheel 3. Then, the detection wheel 3 slides from back to front along the first direction. The above operations are repeated in sequence, and the length and width directions of the photovoltaic panel 19 can be detected. In addition, a spring piece can be set at the connection between the indicating pen 4 and the telescopic rod, so that the indicating pen 4 is always in contact with the writing paper 5, to prevent the appearance of a gap between the indicating pen 4 and the writing paper 5 when the telescopic rod is extended and retracted, resulting in writing failure.

[0045] The walking assembly also includes a connecting seat 9, the connecting column 7 is arranged on the connecting seat 9, the moving rod 6 is provided with a moving groove 601, and the connecting seat 9 is provided with a protrusion 901 adapted to the moving groove 601, and the protrusion 901 slides and extends into the moving groove 601.

[0046] In this embodiment, the connecting seat 9 connects the detection wheel 3 and the telescopic rod, and a moving groove 601 is provided on the moving rod 6. The moving groove 601 extends along the first direction and provides a moving track for the connecting seat 9. A protrusion 901 adapted to the moving groove 601 is provided on the connecting seat 9. The protrusion 901 slides into the moving groove 601 to ensure the smooth movement of the connecting seat 9 in the first direction.

[0047] The detection device further comprises a supporting assembly arranged on the frame 1, and the supporting assembly comprises:

[0048] Turntable 11;

[0049] A plurality of support rods 12 are arranged in a circle on the turntable 11, and the support rods 12 are provided with support blocks 13, and the plurality of support blocks 13 are configured to form the detection position 2;

[0050] The frame 1 is provided with a rotating shaft 14, and the rotating disk 11 is rotatably arranged on the rotating shaft 14;

[0051] The support block 13 is hinged to the support rod 12;

[0052] The turntable 11 is provided with a second telescopic rod 15 , and the second telescopic rod 15 is located at the center of the turntable 11 .

[0053] In this embodiment, a turntable 11 is installed on the frame 1, and a plurality of support rods 12 are arranged in a circle on the turntable 11. A support block 13 is provided on each support rod 12. The number and distribution of the support rods 12 can be adjusted according to the size and shape of the photovoltaic panel 19. The support block 13 is fixed to the end of the support rod 12. The plurality of support blocks 13 are jointly constructed into a detection position 2 for placing the photovoltaic panel 19. The design of the support block 13 can be optimized according to the edge shape of the photovoltaic panel 19 to ensure the stability and accuracy of the placement of the photovoltaic panel 19. At the same time, in order to enable the present device to detect the curved photovoltaic panel 19, a turntable 11 is provided on the frame 1. A second telescopic rod 15 is provided on the turntable 11, and the support block 13 is hinged on the support rod 12. According to the shape of the arc-shaped photovoltaic panel 19, the support block 13 is adjusted to an appropriate angle to support both ends of the photovoltaic panel 19. The second telescopic rod 15 provided at the center of the turntable 11 is extended to a suitable length to abut against the middle of the photovoltaic panel 19. Then the turntable 11 is rotated to make the photovoltaic panel 19 rotate from left to right or from right to left around the rotating shaft 14 as the center of the circle. At this time, the indicating pen 4 is located in the middle of the frame 1 and does not move in the first direction. The indicating pen 4 contacts the arc-shaped surface of the arc-shaped photovoltaic panel 19, and the moving trajectory of the indicating pen 4 only moves back and forth in the second direction.

[0054] The frame 1 is provided with a clamping member, and the clamping member comprises:

[0055] A connection block 16 is disposed below the photovoltaic panel 19, and the connection block 16 is provided with a limiting groove arranged along the second direction;

[0056] Two clamping blocks 17 are spaced apart in the limiting groove and are used to clamp the opposite end faces of the photovoltaic panel 19;

[0057] The bidirectional screw rod 18 connects the clamping block 17 and the connecting block 16 so that the two clamping blocks 17 can move toward or away from each other.

[0058] In this embodiment, the connecting block 16 is arranged below the photovoltaic panel 19, and a limit groove (not shown) is provided on the connecting block 16 along the second direction. The limit groove is used to accommodate and guide the movement of the two clamping blocks 17. The two clamping blocks 17 are arranged in the limit groove at intervals and are used to clamp the opposite end faces of the photovoltaic panel 19. The design of the clamping block 17 can be adjusted according to the size and shape of the photovoltaic panel 19 to ensure the stability and reliability of the clamping. The bidirectional screw rod 18 connects the clamping block 17 and the connecting block 16. By rotating the bidirectional screw rod 18, the two clamping blocks 17 can be moved toward or away from each other, thereby achieving the clamping or loosening of the photovoltaic panel 19, ensuring the stable clamping of the photovoltaic panel 19 during the detection process and reducing the detection error caused by the movement of the photovoltaic panel 19.
