Description

Technical Field

[0001] The utility model relates to the technical field of solar cell production, in particular to a novel solar string welding ribbon welding device. Background Art

[0002] As the concept of green environmental protection is becoming more and more popular, the public's acceptance of green energy is also increasing, and even the use of green energy has become a trend pursued by the public. Photovoltaic power generation has become the dominant green energy because of its low cost and small scope of limitation. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (assemblies), controllers and inverters. The main components are composed of electronic components. After the solar cells are connected in series and packaged for protection, they can form a large-area solar cell assembly. Combined with power controllers and other components, a photovoltaic power generation device is formed. When producing solar cell groups, a string welding machine is required to weld the solar cell groups. The welding principle of the existing string welding machine is to weld the components to be welded by hot pressing. The solar cells are placed on a conveyor belt by a robot, and the welding tape conveyor conveys the welding tape to the solar cell through two rollers through manual adjustment. After the cutting machine cuts it, the welding machine melts the welding tape and welds it on the cell. Multiple single cells are connected in series or in parallel to form a complete battery assembly. Since the specifications of various solar cells are different, the spacing between two welding tapes is different when welding solar cells of different specifications. The traditional new solar string welding welding tape fluxing device has a simple structure and cannot accurately control the conveying length of the welding tape. When welding solar cells of different specifications, it is necessary to stop the machine and manually adjust the spacing between the two welding tapes. The accuracy is poor, the labor burden is heavy, it is very time-consuming, and the production efficiency is low. For this reason, we propose a new solar string welding welding tape fluxing device.

At the same time, the spring relies on its own elastic potential energy to drive the sliding sleeve to move down along the sliding column, so that the outer edge of the clamping wheel is close to the outer surface of the welding belt to prevent the welding belt from shifting. The elastic potential energy of the spring can adapt to welding belts of various diameters. At this time, the friction force generated by the clamping wheel and the arc groove continuously pushes the welding belt forward, realizing the rapid transportation of the solar string welding welding belt while accurately controlling the transportation length of the solar string welding welding belt.

[0016] 2. When welding solar cells of different specifications, it is necessary to adjust the spacing between the two welding strips. The single chip microcomputer controls the operation of the adjustment motor. The output shaft of the adjustment motor drives the worm to rotate, and the worm wheel rotates accordingly, driving the bidirectional lead screw to rotate. As the bidirectional lead screw rotates, the two mounting frames will reciprocate left and right along the slide slot. When the adjustment motor rotates forward, the two mounting frames move outward synchronously. When the adjustment motor rotates reversely, the two mounting frames move inward synchronously, thereby adjusting the spacing between the solar string welding strips. The spacing between the two solar string welding strips can be adjusted quickly and accurately and automatically, which reduces the labor burden and improves the production efficiency of the solar group.

The worm gear 58 is meshed with the worm wheel 55 to provide a stable drive for the transportation of the solar string welding tape.

[0028] The working principle of the novel solar string welding welding ribbon assisting device provided by the utility model is as follows: when the novel solar string welding machine is working, the manipulator puts the solar cells on the conveyor belt in sequence, and the single chip computer 7 controls the conveying motor 57 to operate. The output shaft of the conveying motor 57 drives the worm 2 58 to rotate. Because the worm 2 58 is meshed and connected with the worm gear 2 55, the worm gear 2 55 also rotates, driving the connecting shaft 54 ​​to rotate. Because the inner walls of the two through holes are both mounted in cooperation with the outer surface of the connecting shaft 54, as the connecting shaft 54 ​​rotates, the two conveying wheels 52 and The pulley 56 also rotates accordingly, and the pulley 56 on the front side rotates synchronously through the belt, and the two conveying wheels 52 on the front side also rotate accordingly, driving the welding ribbon in the arc groove to move forward. At the same time, the spring 533 relies on its own elastic potential energy to drive the sliding sleeve 532 to move down along the sliding column 531, so that the outer edge of the clamping wheel 534 is close to the outer surface of the welding ribbon to prevent the welding ribbon from deviating. The elastic potential energy of the spring 533 can adapt to welding ribbons of various diameters. At this time, the friction force generated by the clamping wheel 534 and the arc groove continuously pushes the solar string welding ribbon to move forward, realizing the rapid conveying of the welding ribbon. The conveying length of the welding ribbon can be accurately controlled. When the solar string welding ribbon is conveyed to a suitable length, the cutting machine cuts the solar string welding ribbon, and the welding machine melts the welding ribbon and welds it on the battery cell, so that multiple single battery cells are connected in series or in parallel to form a complete battery assembly. When welding solar cells of different specifications, it is necessary to adjust the spacing between two solar string welding ribbons. The single chip computer 7 controls the operation of the regulating motor 45, and the output shaft of the regulating motor 45 drives the worm 46 to rotate. Because the worm 46 is meshed with the worm wheel 43, the The worm gear 43 rotates accordingly, driving the bidirectional screw rod 44 to rotate. Because the middle part of the mounting frame 42 is threadedly connected to the outer surface of the bidirectional screw rod 44, as the bidirectional screw rod 44 rotates, the two mounting frames 42 will reciprocate left and right along the slide groove 41. The adjusting motor 45 rotates forward, and the two mounting frames 42 move outward synchronously. The adjusting motor 45 reverses and the two mounting frames 42 move inward synchronously, thereby adjusting the spacing of the solar string welding strips. The spacing between the two solar string welding strips can be automatically adjusted quickly and accurately, which reduces the labor burden and improves the production efficiency of the solar panel.
