In the embodiment, the power roller 21 is provided with a fixed ring 29 which is composed of two half rings and is sleeved on the power roller 21. Each fixed ring 29 rotates independently. The cushion plate 41 and the supporting plate 44 are fixedly connected to the corresponding fixed ring 29, so as to realize the hinging of the cushion plate 41 and the supporting plate 44 to the power roller.

[0042] Please refer to Figures 1-6 The lower top mechanism 50 comprises a top head 51 and a top-out cylinder 52. The top head 51 is slidably connected to the rack 10, and the top-out cylinder 52 is installed on the rack 10. The telescopic end of the top-out cylinder 52 is fixedly connected to the top head 51. The top-out cylinder 52 pushes the top head 51 to move downward to press the photovoltaic module plate to the V-shaped supporting plate 44 and the cushion plate 41, so as to protrude the glass.

[0043] Please refer to Figures 1-6 The lower top mechanism 50 further comprises a top plate 53 and a spring piece 54. Two top plates 53 are hinged to the tip of the top head 51. The outer end of the top plate 53 is hingedly connected to a connecting rod 55 which is slidably connected to the top head 51. One end of the spring piece 54 is fixedly connected to the rack 10, and the other end of the spring piece 54 is movably abutted to the top plate 53. A sliding groove is formed in the upper end of the connecting rod 55, and a screw is arranged on the top head 51 to move in the sliding groove. When not top-out, the two top plates 53 are hung by the respective connecting rods 55 to keep horizontal, and the two supporting plates 44 are kept horizontal under the support of the respective supporting cylinders 45, thereby forming a channel to facilitate the photovoltaic module plate to pass through.

Until the top plate 53 abuts against the spring piece 54, the downward pressure on the photovoltaic module plate is maintained, so that the photovoltaic module plate can be closely attached to the supporting plate 44 to facilitate the protrusion of the glass.

[0044] Please refer to Figures 2-7The scraping mechanism 60 comprises a scraping motor 61, a rotating shaft 62 and a material hopper 63. The rotating shaft 62 is rotatably connected to the frame 10. The output end of the scraping motor 61 is connected to the rotating shaft 62 by a belt. The rotating shaft 62 is provided with a cutter head 64. The cutter head 64 is arranged on the outer circle of the rotating shaft 62. The rotating shaft 62 is located in the material hopper 63. The scraping motor 61 drives the rotating shaft 62 to rotate at a high speed through a belt pulley. The rotating shaft 62 drives all the cutter heads 64 to rotate. The protruding glass is scraped by the cutter heads 65 on the outer circle of the cutter head 64. The degree of protrusion of the glass is adjusted by adjusting the inclination angle of the backing plate 41, so as to ensure that the glass cup is scraped clean.

[0045] The working principle of the automatic glass removing machine for the photovoltaic panel is as follows: the photovoltaic panel is inserted between the steel mesh 27 and the support plate 28 from the left end of the frame 10. When the photovoltaic panel reaches the first pressing roller 23, the first sensor 26 senses the entry of the photovoltaic panel and triggers the first pressing cylinder 25 to act, thereby pressing down the first pressing roller 23. The power roller 21 abuts against the photovoltaic panel and forwards the photovoltaic panel. The photovoltaic panel is heated by the heating mechanism 30 and then reaches the second power roller 21. The second sensor 26 is two photoelectric switches arranged on the left and right sides of the second power roller 21. When the left second sensor 26 senses the entry of the photovoltaic panel, it triggers the second pressing cylinder 25 to act, thereby pressing down the second pressing roller 23 and forwarding the photovoltaic panel. The photovoltaic panel passes through the support mechanism 40 and the lower lifting mechanism 50 and then reaches the third power roller 21. The third sensor 26 senses the photovoltaic panel and triggers the driving motor 22 to stop. The lower lifting mechanism 50 abuts against the photovoltaic panel on the support mechanism 40, thereby bending the photovoltaic panel to make the glass crack and protrude from the opening. At the same time, the cutter head 64 starts to rotate in the forward direction to scrape the glass at the opening. Then, the driving motor 22 reverses to pull the photovoltaic panel back. At this time, the glass at the front end of the photovoltaic panel is scraped off. When the right second sensor 26 cannot detect the photovoltaic panel, it indicates that the glass at the front end of the photovoltaic panel is scraped off. At this time, the driving motor 22 rotates in the forward direction and the first and second pressing cylinders 25 retract. The ejecting cylinder 52 re-ejects. The photovoltaic panel moves forward to the position of the third sensor 26. At the same time, the third pressing cylinder 25 acts. The third pressing roller 21 and the third power roller 21 pull the photovoltaic panel to the right. At the same time, the cutter head 64 reverses to scrape off the glass at the rear end of the photovoltaic panel. In summary, the roller conveying mechanism 20 moves with the photovoltaic panel. The lower lifting mechanism 50 presses the flat photovoltaic panel into the concave support mechanism 40, thereby breaking the glass on the photovoltaic panel and making the glass protrude from the bottom opening. The scraping mechanism 60 scrapes off the protruding glass. In summary, one device realizes the effect of automatic glass breaking and stripping, thereby improving the disassembly efficiency and increasing the integration degree.

[0046] The above merely provides examples of the present application, and is not intended to limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes.
