[0002] Photovoltaic panels are thin, solid-state photovoltaic cells made almost entirely of semiconductor materials that generate direct current when exposed to sunlight. To ensure their stability, they are typically mounted on a fixed frame.

[0003] Referring to a Chinese patent with application number 202311369187.8, an automatic photovoltaic panel installation device is disclosed. The entire process is automated and can be freely adjusted according to installation requirements. It has a wide range of applications. Through research on the above-mentioned automatic photovoltaic panel installation device, it was found that the above-mentioned device can only automatically transport the photovoltaic panel to the top of the fixing frame, and as for how to fix the photovoltaic panel and the fixing frame, it is not involved.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. In the present invention, after the photovoltaic panel is adsorbed by the photovoltaic panel loading component, the photovoltaic panel is lifted and moved to the installation height by the lifting device, and then the photovoltaic panel is driven to rotate by the photovoltaic panel loading component so that its angle matches the inclination angle of the top of the fixing frame, thereby positioning the photovoltaic panel on the top of the fixing frame. No manual positioning is required, and the mounting bolts are tightened into the threaded holes at the top of the fixing frame by the bolt tightening component, thereby automatically completing the fixed installation of the photovoltaic panel. Compared with the existing technology, the installation efficiency is high.

[0043] 2. In the present invention, the output rod of the No. 2 cylinder pushes the L-shaped metal block upward, thereby driving the push bar to move upward. The upward movement of the push bar drives the upper and lower metal pressure plates to move upward together, so that the tops of the two elastic plastic pressure strips hinged to the push bar move upward, causing the curvature of the two elastic plastic pressure strips to decrease and gradually move closer to the middle, limiting the nut of the mounting bolt inside the hexagonal socket wrench. At the same time, the left and right elastic plastic pressure strips clamp the threaded outer wall of the mounting bolt to prevent the bolt from shaking, so that it can better fit with the threaded hole on the fixing frame during the subsequent installation process, and also prevent the mounting bolt from falling off from the inside of the hexagonal socket wrench.

[0044] 3. In the present invention, after the mounting bolt is screwed into the threaded hole, the output rod of the No. 2 cylinder pulls the L-shaped metal block downward, further driving the push bar to move downward. The downward movement of the push bar drives the upper and lower metal pressure plates to move together, applying downward pressure on the top of the left and right elastic plastic pressure strips, causing the left and right elastic plastic pressure strips to be stretched open, making it easier for the nut part of the mounting bolt to pass through the countersunk groove and the inside of the round hole.

[0060] For further details, please refer to Figures 5 to 7 as well as Figure 8 As shown:

[0061] The bolt limiting component 400 includes a limiting plate 401, a circular hole 402, a sinking groove 403, a sliding groove 404, a positioning hole 405, an elastic plastic pressure strip 406, a metal pressure plate 407, a push bar 408, an L-shaped metal block 409 and a second cylinder 4010. The limiting plate 401 is fixedly installed on the left and right sides of the flip frame 302. The circular hole 402 is provided on the upper and lower front sides of the limiting plate 401, and the sinking groove 403 is provided on the upper and lower sides. The rear wall of the circular hole 402 is formed on the rear wall of the circular hole 402 and passes through the interior of the limiting plate 401. The sliding groove 404 is formed on the upper and lower parts of the side surface of the limiting plate 401 away from the flip frame 302. The interior of the sliding groove 404 is connected to the interior of the circular hole 402. The positioning hole 405 is formed on the lower part of the rear wall of the circular hole 402 symmetrically with the central axis of the circular hole 402. The elastic plastic pressure strip 406 is symmetrically arranged on the interior of the circular hole 402 with the central axis of the circular hole 402. The two elastic plastic strips 406 are symmetrically arranged in an arc shape that arches outwards. The metal pressure plate 407 is slidably installed inside the slide groove 404 and extends to the inside of the circular hole 402. The metal pressure plate 407 is hinged to the top of the two positioning holes 405 by a pin. The push strip 408 is slidably installed on the side of the limit plate 401 away from the flip frame 302, and the upper and lower ends of the push strip 408 are respectively fixedly connected to the upper and lower metal pressure plates 407. The L-shaped metal block 409 is fixedly installed on the outside of the push strip 408. The No. 2 cylinder 4010 is fixedly installed on the back of the limit plate 401 through a fixed bracket, and the top of its output rod is fixedly connected to the bottom of the L-shaped metal block 409. The output end of the suction cup 304 is connected to the output end of the external negative pressure device through a soft conduit. The front of the suction cup 304 protrudes from the front of the limit plate 401 by 10±1mm.

[0062] Specifically, the nuts of the four mounting bolts are placed inside the four hexagonal socket wrenches 505, so that the threaded parts of the mounting bolts pass through the recessed grooves 403. Subsequently, the No. 2 air cylinder 4010 is started, and the L-shaped metal block 409 is pushed upward by the output rod of the No. 2 air cylinder 4010, thereby driving the push bar 408 to move upward. The upward movement of the push bar 408 drives the upper and lower metal pressure plates 407 to move upward together, so that the tops of the two elastic plastic pressure strips 406 hinged to the push bar 408 move upward, causing the curvature of the two elastic plastic pressure strips 406 to decrease and gradually move closer to the middle, limiting the nut of the mounting bolt inside the hexagonal socket wrench 505. At the same time, the left and right elastic plastic pressure strips 406 clamp the threaded outer wall of the mounting bolt. To prevent the bolt from shaking and to facilitate better engagement with the threaded hole on the fixing frame during the subsequent installation process, the mounting bolt is tightened into the threaded hole at the top of the fixing frame through the bolt screwing component 500, and after the mounting bolt is screwed into a part of the inner threaded hole at the top of the fixing frame, the output rod of the No. 2 cylinder 4010 pulls the L-shaped metal block 409 downward to move, further driving the push bar 408 to move downward together, and the downward movement of the push bar 408 drives the upper and lower metal pressure plates 407 to move together, applying downward pressure to the top of the left and right elastic plastic strips 406, causing the left and right elastic plastic strips 406 to be stretched open, making it convenient for the nut part of the mounting bolt to pass through the inside of the recessed groove 403 and the circular hole 402.

[0063] For further details, please refer to Figure 5 、 Figure 6 as well as Figure 8 As shown:

[0064] The bolt tightening component 500 includes a guide column 501, a linear bearing 502, a movable plate 503, a high-torque reduction motor 504, a hexagonal socket wrench 505 and a No. 1 cylinder 506. The guide column 501 is fixedly mounted on the upper and lower parts of the back of the limit plate 401, and the linear bearing 502 is slidably mounted on the periphery of the upper and lower guide columns 501. The movable plate 503 is fixedly mounted on the surfaces of the upper and lower linear bearings 502 and is parallel to the limit plate 401. The high-torque reduction motor 504 is fixedly mounted on the upper and lower parts of one side of the movable plate 503 away from the limit plate 401, and its output shaft movably passes through the interior of the movable plate 503 and extends to its front periphery. The hexagonal socket wrench 505 is fixed It is installed on the output shaft ends of the upper and lower high-torque reduction motors 504, and its center is concentric with the center of the sink 403. The diameter of the hexagonal socket wrench 505 is smaller than the diameter of the sink 403. The No. 1 cylinder 506 is vertically distributed and fixedly installed on a side of the flip frame 302 close to the limit plate 401, and its output rod end is fixedly connected to the back of the movable plate 503. The maximum distance between the left and right elastic plastic strips 406 is smaller than the inner diameter of the hexagonal socket wrench 505. The center distance between the upper and lower hexagonal socket wrenches 505 and the center distance between the left and right hexagonal socket wrenches 505 are all adapted to the upper and lower hole spacing and left and right hole spacing of the bolt assembly holes of the photovoltaic panel to be installed.

[0065] Specifically, by placing the nut of the mounting bolt inside the four hexagonal socket wrenches 505, the threaded part of the mounting bolt passes through the recessed groove 403, and the hexagonal socket wrench 505 is driven to rotate by the output shaft of the high-torque reduction motor 504, further driving the mounting bolt inside the hexagonal socket wrench 505 to rotate together. At the same time, the output rod of the No. 1 cylinder 506 pushes the movable plate 503 to move in the direction of the limit plate 401, further driving the high-torque reduction motor 504 and the hexagonal socket wrench 505 to move together, providing a screw-in effect of the hexagonal socket wrench 505, so that the mounting bolt is screwed into the threaded hole on the fixing frame, locking the photovoltaic panel to the top of the fixing frame.

[0066] In this solution, an automatic photovoltaic panel installation device is provided. When in operation, four Forma wheels provided at the bottom of the base 100 support the entire device and provide a moving function, so as to move the device to the photovoltaic installation location.

[0067] The worker places the nuts of the four mounting bolts inside the four hexagonal socket wrenches 505, so that the threaded parts of the mounting bolts pass through the recessed groove 403. Then, the No. 2 air cylinder 4010 is started, and the output rod of the No. 2 air cylinder 4010 pushes the L-shaped metal block 409 upward, thereby driving the push bar 408 to move upward. The upward movement of the push bar 408 drives the upper and lower metal pressure plates 407 to move upward together, so that the tops of the two elastic plastic pressure strips 406 hinged to the push bar 408 move upward, causing the curvature of the two elastic plastic pressure strips 406 to decrease and gradually move closer to the middle, pressing the hexagonal socket wrench 505. The nut of the internal mounting bolt is limited, and the two elastic plastic strips 406 on the left and right clamp the threaded outer wall of the mounting bolt to prevent the bolt from shaking, so that it can better fit with the threaded hole on the fixing frame during the subsequent installation process, and also prevent the mounting bolt from falling off from the inside of the hexagonal socket wrench 505. Then, the worker places the photovoltaic panel on the front of the photovoltaic panel feeding component 300, and absorbs the photovoltaic panel through multiple suction cups 304. In addition, the position of the photovoltaic panel needs to be adjusted to be centered and on the front of the flip frame 302, ensuring that the mounting holes at the four corners of the photovoltaic panel are located on the front of the four sinks 403;

[0068] Then, the lifting device 200 pushes the square tube frame 301 upward to move, and the square tube frame 301 moves upward to drive the photovoltaic panel feeding component 300, the bolt limiting component 400 and the bolt tightening component 500 to move upward as a whole, and the photovoltaic panel adsorbed by the multiple suction cups 304 is lifted up to the installation height. Then, the output rod of the electric cylinder 306 pushes the pushing block 305 to move, so that the photovoltaic panel feeding component 300, the bolt limiting component 400, the bolt tightening component 500 and the adsorbed photovoltaic panel are rotated forward along the top of the square tube frame 301 as a whole, until the angle of the photovoltaic panel matches the inclination angle of the fixing frame, so that the bottom of the photovoltaic panel rests on the top of the fixing frame, and the electric cylinder 306 is closed. The bolts inside the four hexagonal socket wrenches 505 just correspond to the positions of the four threaded holes on the top of the fixing frame. Then, the output shaft of the high-torque reduction motor 504 drives the hexagonal socket wrench 505 to rotate, further driving the The mounting bolts inside the tube wrench 505 rotate together. At the same time, the output rod of the No. 1 cylinder 506 pushes the movable plate 503 to move in the direction of the limit plate 401, further driving the high-torque reduction motor 504 and the hexagonal socket wrench 505 to move together, providing the hexagonal socket wrench 505 with a screwing effect, so that the mounting bolts are screwed into the threaded holes on the fixing frame. When the mounting bolts are screwed into the threaded holes, the output rod of the No. 2 cylinder 4010 pulls the L-shaped metal block 409 downward to move, further driving the push bar 408 to move downward together. The downward movement of the push bar 408 drives the upper and lower metal pressure plates 407 to move together, applying downward pressure on the top of the left and right elastic plastic strips 406, causing the left and right elastic plastic strips 406 to be stretched open, making it convenient for the nut part of the mounting bolt to pass through the inside of the sink 403 and the round hole 402, locking the photovoltaic panel to the top of the fixing frame, thus completing the photovoltaic panel installation.
