[0017] Figure 1 It is a schematic diagram of the side structure of a processing device for recycling photovoltaic modules according to an embodiment of the present invention, wherein the rotating shaft is blocked.

[0018] Reference Figure 1 According to an embodiment of the present invention, a processing device for recycling photovoltaic modules is arranged on a work surface, including: a transport device 1, a base 2, a lifting device 3 and a degumming device 4. The transport device 1 and the base 2 are respectively fixed on opposite sides of the work surface, and a conveyor belt for transporting frameless photovoltaic modules 5 is movably provided on the surface of the transport device 1. The fixed end of the lifting device 3 is mounted on the base 2, and the movable end of the lifting device 3 is fixedly connected to the degumming device 4. When the frameless photovoltaic module 5 enters the base 2, the degumming device 4 heats the frameless photovoltaic module 5 to change the adhesion of the glue layer inside the frameless photovoltaic module 5, and the base 2 separates the battery and glass in the frameless photovoltaic module 5 through differential transportation.

[0019] Figure 2 The figure is a schematic diagram of the top structure of a processing device for recycling photovoltaic modules according to an embodiment of the present invention.

[0020] Refer to Figure 1 and Figure 2Specifically, the base 2 consists of a transfer platform 21, a pair of fixed rods 22, a plurality of rotating shafts 23 and a driving motor 24. The transfer platform 21 is installed on the work surface by welding or other fixing methods. A conveyor belt for transmitting the frameless photovoltaic module 5 is provided on the transfer platform 21. There is no height difference between the frameless photovoltaic module 5 from the surface of the transportation device 1 to the surface of the transfer platform 21. The surface of the transfer platform 21 and the fixed end of the lifting device 3 are kept relatively still by bolts and other connectors to ensure the stability and coordination of the entire device during operation. Each fixed rod 22 is arranged relative to each other, and the degumming device 4 is arranged across the two fixed rods 22. Relying on the support provided by the fixed rods 22, the degumming device 4 can maintain an accurate and stable working position. At the same time, a gear assembly is arranged inside each fixed rod 22, and each rotating shaft 23 rotates through the transmission action of the gear assembly.

[0021] When the driving motor 24 is started, the power generated by it is transmitted through the rotating shaft 23 connected thereto, causing all the rotating shafts 23 to rotate synchronously. Under the action of the rotating shaft 23 rotating, the glass of the frameless photovoltaic assembly 5 placed thereunder moves accordingly. With the help of the speed difference between the transfer platform 21 and the rotating shaft 23, the separation operation of the battery and the glass in the frameless photovoltaic assembly 5 is realized.

[0022] Figure 3 A schematic structural diagram of a four-axis transmission mechanism according to an embodiment of the present invention, wherein the glue remover is omitted.

[0023] Specifically, the lifting device 3 includes a stabilizing bar 31, two support columns 32, a balancing frame 33 and a four-axis transmission mechanism 34. The stabilizing bars 31 are respectively arranged across the top of the fixed rods 22, and each support column 32 is fixedly connected to one of the fixed rods 22 in a vertical manner. Each support column 32 is located on the same side of the fixed rod 22, and the stabilizing bar 31 is located on the other side opposite to the fixed rod 22. The two sides of the balancing frame 33 are respectively fixedly connected to each stabilizing bar 31 and each support column 32 to ensure that the overall structure maintains a relatively stable state during the lifting process, and avoids structural deformation or instability due to uneven force. The fixed end of the four-axis transmission mechanism 34 is fixedly connected to the transfer platform 21 through a specific connection structure, and this connection ensures the stability of the balancing frame 33 during the lifting process and the effectiveness of power transmission. The movable end of the four-axis transmission mechanism 34 is respectively connected to each fixed rod 22 by a screw rod 346 transmission.

[0024] When the four-axis transmission mechanism 34 is started, the power transmission mechanism inside it will transmit power to the fixed rod 22 connected thereto according to the transmission of the screw rod 346. Under the driving force generated by the transmission of the screw rod 346, the fixed rod 22 will produce a corresponding vertical displacement, thereby driving the degumming device 4 straddling the fixed rod 22 to perform a synchronous lifting action, so as to meet the requirements of the corresponding process operation or function for the height adjustment of the degumming device 4. In this embodiment, the degumming device 4 is a short-wave infrared light source to avoid affecting the glass in the frameless photovoltaic module 5 during the heating process. Preferably, during the use of the degumming device 4, the temperature of the degumming device 4 is set to 40°C to 200°C, preferably 110°C, and the heating time is 2 minutes. The spacing between the transmitting end of the degumming device 4 and the surface of the frameless photovoltaic module 5 is between 100mm and 300mm, which is specifically changed according to the thickness of different types of frameless photovoltaic modules 5, usually 200mm.

[0025] Furthermore, the four-axis transmission mechanism 34 includes: a starting motor 341, a longitudinal transmission shaft 342, two transverse transmission shafts 343, two transmission devices 344, a plurality of positioning seats 345 and a plurality of screws 346. The movable end of the starting motor 341 is connected to the longitudinal transmission shaft 342 through a corresponding mechanical connection structure to ensure that the power generated by the operation of the starting motor 341 can be effectively transmitted to the longitudinal transmission shaft 342, providing initial power guarantee for the subsequent transmission process. The longitudinal transmission shaft 342 is in a key power transmission position in the entire transmission system, and the two transverse transmission shafts 343 respectively establish a rotation connection relationship with the longitudinal transmission shaft 342 through the corresponding transmission devices 344. The transmission device 344 is a gear assembly, and the transmission device 344 can accurately transmit the rotation of the longitudinal transmission shaft 342 to the two transverse transmission shafts 343, so that the two transverse transmission shafts 343 can achieve synchronous and stable rotation under the drive of the longitudinal transmission shaft 342. Each positioning seat 345 is located at one end of the balance frame 33, and a screw rod 346 is rotatably disposed inside each positioning seat 345. The screw rod 346 is rotatably connected to the transverse transmission shaft 343 by gear transmission. The fixing rod 22 and each support column 32 are rotatably connected to a screw rod 346.

[0026] When the starter motor 341 receives the operation command and starts to operate, the power generated by it is sequentially transmitted to each screw rod 346 through the longitudinal transmission shaft 342, the transverse transmission shaft 343 and the gear transmission. Under the driving force generated by the rotation of the screw rod 346, the fixed rod 22 or each support column 32 will perform corresponding lifting and lowering movements along the axial direction of the screw rod 346, thereby realizing the vertical position adjustment of the degumming device 4 and each rotating shaft 23 in the entire device.

[0027] Furthermore, in order to facilitate the adjustment of the height of the degumming device 4, in this embodiment, a tester 6 is further provided on the side of the fixing rod 22 close to the transport device 1. During the transportation of the frameless photovoltaic module 5, the tester 6 measures the thickness of the frameless photovoltaic module 5 and feeds back to the starter motor 341. The starter motor 341 can set the speed and time corresponding to different thicknesses, thereby controlling the moving distance of the degumming device 4.

[0028] When the photovoltaic modules are recycled by this device, the photovoltaic modules need to be processed to remove the back plate to form the corresponding frameless photovoltaic modules 5. After the transport device 1 transports the frameless photovoltaic modules 5 between the fixing rod 22 and the transfer platform 21, the tester 6 tests the thickness of the frameless photovoltaic modules 5 and starts the motor 341 to adjust the lifting height of the degumming device 4 according to the test results. After the degumming device 4 is started, the short-wave infrared rays heat the frameless photovoltaic modules 5, thereby releasing the adhesion state inside the frameless photovoltaic modules 5. Each rotating shaft 23 drives the glass of the frameless photovoltaic modules 5 below respectively, so that there is a difference in the moving speed between the glass of the frameless photovoltaic modules 5 and the battery cell, thereby separating the two.

[0029] In summary, the present invention changes the adhesion state between the glass and the battery cells in the frameless photovoltaic module by heating with a degumming device, and performs differential transportation in the base, thereby separating the battery cells and glass in the frameless photovoltaic module.
