Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel encapsulation, and particularly to a packaging device for solar photovoltaic panel production. Background Art

[0002] Materials such as solar cells, EVA (ethylene-vinyl acetate copolymer), glass, and backsheets are pressed together under high-temperature vacuum conditions to form a photovoltaic module with certain rigidity and sealing performance. During the production process of photovoltaic modules, usually, after the series and parallel connection of solar cells, a glass plate is covered on the upper side to protect the solar cells, and a backsheet is fixed on the lower side to prevent moisture intrusion and provide mechanical support for the photovoltaic module. Encapsulation glue is used for encapsulation treatment between the three to improve the stability and durability of the photovoltaic module.

[0003] During the process of connecting the tested and sorted solar cells in series or parallel and automatically arranging the solar cell strings on the glass plate for welding, unstable welding temperature, too short welding time, and poor solder fluidity will cause the surface of the welding point to seemingly be well connected, but in fact, no firm metallurgical bond is formed between the solder and the solar cell and the solder tape substrate, resulting in false soldering. On the other hand, a general typesetting machine will automatically arrange the solar cell strings on the glass plate, and the typesetting machine only responsible for docking has general adaptability to solar cell strings of different sizes, so that the solder at the welding point fails to completely melt or firmly bond with substrates such as solar cells and solder tapes, resulting in the detachment of the welding point during subsequent production or use, and further leading to the interruption of the electrical connection between solar cells, affecting the current transmission and power generation efficiency of the photovoltaic module; moreover, string soldering, typesetting, and lamination are carried out at multiple workstations, which will increase the quality fluctuations caused by transfer and waiting between processes, thus unable to ensure the stability and consistency of the product. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the solder at the welding point fails to completely melt or firmly bond with substrates such as solar cells and solder tapes in the prior art, resulting in the detachment of the welding point during subsequent production or use, and further leading to the interruption of the electrical connection between solar cells, affecting the current transmission and power generation efficiency of the photovoltaic module, and to propose a packaging device for solar photovoltaic panel production.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme:

[0051] As Figure 1 and Figure 3 As shown, in one embodiment: the rotating assembly 23 includes a reduction motor 231 installed on the top of the lifting table 22, a transmission wheel 232 installed on the outer side of the output end of the reduction motor 231, and a rotating shaft 233 installed at the bottom of the transmission wheel 232 and connected to the middle part of the top end of the movable boss 401; used to adjust the direction of the battery module.

[0052] As Figure 2 and Figure 9 As shown, in one embodiment: the negative pressure extraction structure 3 includes an air extraction pump 301 installed on the side of the lifting table 22 away from the transmission wheel 232, an air delivery pipe 302 installed on the outer side of the output end of the air extraction pump 301, a hollow air ventilation frame 303 sleeved on the outer side of the air delivery pipe 302, rubber suction cups 304 installed at the bottom of the hollow air ventilation frame 303 and used to adsorb the battery module string, EVA, glass, and backplane materials, and a one-way valve 305 installed at the bottom of the hollow air ventilation frame 303 and used for one-way ventilation; the air extraction pump 301 is connected to the hollow air ventilation frame 303 through the air delivery pipe 302, and the rubber suction cups 304 are evenly distributed at the bottom of the hollow air ventilation frame 303, used to adsorb and sequentially lay the battery module string, EVA, glass, and backplane materials.

[0053] As Figure 4 and Figure 5As shown, in one embodiment: the pushing cylinder 402 and the L-shaped locking frame 403 are in an embedded structure at the bottom of the movable boss 401. The L-shaped locking frame 403 and the pushing cylinder 402 are arranged at equal intervals at the bottom of the movable boss 401. The L-shaped locking frame 403 forms a sliding structure with the directional slide rail through the surface chute; the positioning slide rail 405 restricts the movement path of the L-shaped locking frame 403 to ensure the accuracy of typesetting.

[0054] As Figure 6 shown, in one embodiment: the L-shaped locking frames 403 are symmetrically distributed on both sides of the bottom of the movable boss 401, and the surface of the L-shaped locking frame 403 does not contact the welding head of the manipulator laser welder 604.

[0055] As Figure 10 shown, in one embodiment: the rotating abutting pieces 505 are symmetrically distributed on both sides of the bottom of the movable boss 401, and the rotating abutting pieces 505 form a gear transmission structure with the locking gear 503 through the transverse rack 502.

[0056] As Figure 9 shown, in one embodiment: the rubber suction cups 304 are equally spaced at the bottom of the hollow ventilation frame 303, and the surface of the rubber suction cup 304 does not contact the surface of the L-shaped locking frame 403 with the largest extension.

[0057] Specifically, when a packaging device for producing solar photovoltaic panels is used: start the power supply of the device to ensure that all components are in normal working condition, then start the belt conveyor 1, and transport the materials such as the battery assembly string to be processed to each processing station through the end face of the belt. Start the push cylinder 402 of the adjustable plate arrangement structure 4, and the push cylinder 402 drives the L-shaped lock frame 403 to slide at the bottom of the movable boss 401, and connect the tested and classified battery cells in series. The concave and convex texture 404 at the bottom of the L-shaped lock frame 403 fits tightly with the periphery of the battery cell to ensure the stability of the battery cell during the typesetting process. The positioning slide rail 405 limits the moving path of the L-shaped lock frame 403 to ensure the accuracy and consistency of the typesetting. At the same time, the transverse rack 502 at the bottom of the fixed bracket 501 drives the locking gear 503 to rotate, and the locking gear 503 drives the rotating plate 505 to rotate. The rotating plate 505 is closely attached to the surface of the battery cell through the outer rubber cap 102, which limits the movement of the battery string and ensures that it remains stable during the typesetting process. Then start the DC motor 601, which drives the threaded rod 602 to rotate, and cooperates with the linear shafts 101 on both sides and the built-in threaded grooves 100 of the axis moving platform to make the Y-axis moving platform 603 move in the horizontal direction. The robot laser welder 604 is installed at the bottom of the Y-axis moving platform 603, and the welding points of the battery string are found according to the preset program to perform precise welding. During the welding process, the surface of the L-shaped lock frame 403 does not contact the welding head of the robot laser welder 604, ensuring smooth welding. Finally, the vacuum pump 301 is turned on, and the vacuum pump 301 provides negative pressure to the hollow ventilation frame 303 through the air supply pipe 302. The rubber suction cup 304 adsorbs the battery component string, EVA, glass and backboard materials under the action of negative pressure. The lifting platform 22 rises under the drive of the lifting cylinder 21, and brings the adsorbed materials to the specified height. The rotating component 23 adjusts the direction of the material as needed to ensure the accuracy of laying. The negative pressure extraction structure 3 releases the adsorption force and lays the materials in the specified position in sequence. The belt conveyor 1, the vertical support 2, and the lifting cylinder 21 are used to realize rapid transportation and docking between the various workstations, so that the device reduces the transportation and waiting time between processes, reduces quality fluctuations, and ensures the stability and consistency of the product.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
