Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-6 The present invention provides a technical solution: a whole-glass separator for retired photovoltaic panels, comprising: a chassis device 1, a protective cover 8, a central control machine 9 and an electrical cabinet 10.

[0020] The chassis device 1 comprises a transverse bracket 11 and a supporting column 12, which are fixedly connected to form a square frame chassis device 1. The side baffles 6 are fixedly installed on the upper end of the chassis device 1 in a front-to-back symmetrical manner.

[0021] The side baffle 6 is provided with a conveyor 4, which is a roller conveyor, that is, two relatively rotating rollers are used to clamp the photovoltaic panel and advance it.

[0022] The conveyor 4 includes several pairs of rollers, among which the pair at the edge are transmission rollers 7, a sprocket 41 is installed at one end of the roller, a transmission gear 71 is installed at the end of the transmission roller 7, the two transmission gears 71 are meshed, and the transmission gears 71 and the sprocket 41 on the same horizontal line are synchronously driven through a chain belt, and one pair of rollers is connected to the driving mechanism 3.

[0023] The driving mechanism 3 includes a servo motor 31 and a reducer 32. The servo motor 31 drives the reducer 32, and the reducer 32 is connected to the rotating shaft of one of the rollers of the conveyor 4. The servo motor 31 and the reducer 32 drive the rotating shaft of one roller to drive the roller to rotate. The roller drives all the rollers on the same horizontal line to rotate through the sprocket 41 and the transmission gear 71 of the transmission roller 7, and then drives the rollers on another horizontal line to rotate in the opposite direction, so as to realize the synchronous rotation of all rollers and transport the photovoltaic panels.

[0024] The feed end of the conveyor 4 is designed with a pneumatic adjustment and correction device 101. The pneumatic adjustment and correction device 101 is composed of two cylinders driving telescopic rods. A baffle is provided at the end of the telescopic rod. As the baffle moves driven by the telescopic rod, the photovoltaic panel entering the conveyor 4 is corrected to keep moving in a straight line without deviation.

[0025] A scraping mechanism 5 is arranged at the center position on the chassis device 1, and the scraping mechanism 5 comprises a side fixing plate 51 and a U-shaped chassis 57. The side fixing plates 51 are symmetrically mounted at both ends of the U-shaped chassis 57, and a curved feeding roller 55 is rotatably mounted between the side fixing plates 51. A pressure plate 54 is arranged directly above the curved feeding roller 55.

[0026] A fixed platform 58 is fixedly installed on the upper surface of the U-shaped chassis 57, and a cutter 59 is installed on the fixed platform 58. The blade of the cutter 59 connects with the pressure plate 54 and the discharge end of the curved feeding roller 55 to scrape and cut the glass of the passing photovoltaic panel. The scraped and cut glass falls freely onto the unloading conveying line 2 below, and the photovoltaic panel continues to move forward.

[0027] The two ends of the pressure plate 54 are rotatably connected to the swing arm 52, and the upper end of the swing arm 52 is fixedly connected by a connecting rod 53 to achieve synchronous movement of the swing arms 52 at both ends. The swing arm 52 is rotatably connected to the side fixed plate 51, and the middle position of the swing arm 52 is connected to a spring 56, and the other end of the spring 56 is fixedly connected to a fixed platform 58.

[0029] A resistance heating device 102 is fixedly installed in the side baffle 6. The resistance heating device 102 is located on the feeding side of the scraping mechanism 5 to heat the photovoltaic panel so that the glass can be separated from the photovoltaic panel more easily.

[0030] The electrical cabinet 10 includes a temperature detection control system, which is mainly composed of a temperature sensor. The temperature of the resistance heating plate 581 and the resistance heating device 102 is adjusted by sensing the temperature inside the protective cover 8 through the temperature sensor.

[0031] The protective cover 8 plays a certain role in heat insulation to prevent heat from dissipating and ensure the temperature inside the conveyor 4.

[0032] Working principle: The conveyor 4 receives the photovoltaic panel, and then adjusts the position of the photovoltaic panel through the pneumatic adjustment and correction device 101, and then starts the conveyor 4 to transfer the photovoltaic panel. During the transfer process, the pneumatic adjustment and correction device 101 can maintain the position of the photovoltaic panel to prevent it from shifting; The photovoltaic panel first arrives at the resistance heating device 102 for heating. The photovoltaic panel is heated to between 120°C and 140°C. The heated photovoltaic panel is sent to the scraping mechanism 5 to scrape off the glass. The separated glass falls into the unloading conveying line 2 for output.
