[0002] MMB photovoltaic ribbon, also known as multi-busbar ribbon, is a key material in photovoltaic modules. It plays a crucial role in improving module power and efficiency, and also demonstrates significant advantages in reducing silver paste usage and minimizing the impact of microcracks. With a circular cross-section and a diameter between 0.2-0.4 mm, modules made with MMB ribbon can effectively reduce shading area by 30% and lower module series resistance compared to traditional two-busbar, three-busbar, and four-busbar technologies, increasing total module power by over 3% and reducing silver paste usage by over 30%. However, due to its small diameter and inherent flexibility, the small diameter and significant bending properties of MBB ribbon make it prone to large-scale bending deformation during transmission and segmentation cutting.

First, the photovoltaic welding strip is heated by the feeding conveyor and conveyed into the shaping tube. Then, the slitting blade cuts the photovoltaic welding strip into segments inside the shaping tube. The resulting photovoltaic welding strip segments can gradually cool and form inside the shaping tube. The air jet pipe then blows the photovoltaic welding strip segments into the discharge conveyor in a straight structure without bending deformation for unloading. In addition, during the process of conveying the photovoltaic welding strip segments in the shaping tube, the rotating drum passes between the liquid inlet pipe and the liquid outlet pipe, and between the air inlet pipe and the air outlet pipe. In the first time after the slitting process, the cut surface structure of the photovoltaic welding strip segments is passivated in a timely manner, and the outer surface of the photovoltaic welding strip segments is dried and cooled and shaped more quickly. This solves the technical problem that the small diameter and significant bending performance of MBB welding strips make them prone to large-scale bending deformation during the transmission and segment cutting process, which affects the subsequent processing effect and welding quality.

Each shaping tube 23 has a shaping cavity 2301 structure. A sealing plug 24 is slidably connected to the front side of the shaping cavity 2301 of each shaping tube 23. Each sealing plug 24 has a main through cavity 2401 structure. A fixing ring 25 is fixedly connected to the front ends of all the sealing plugs 24, and the sealing plugs 24 extend forward through the fixing ring 25. Two electric adjusting push rods 26 are installed inside the rotating drum 22. The telescopic ends of the two electric adjusting push rods 26 are fixedly connected to the fixing ring 2401. 5; A feeding conveyor 3 and a discharging conveyor 4 are sequentially installed on the mounting frame 1; the feeding conveyor 3 has three feeding holes 301, and the feeding holes 301 are connected to the shaping holes 2301 of the corresponding shaping tubes 23; the discharging conveyor 4 has three discharging holes 401, and the discharging holes 401 are connected to the shaping holes 2301 of the corresponding shaping tubes 23; a ring-shaped groove 2201 structure is opened on the rear side of the rotating drum 22; a reciprocating transmission mechanism 51 is installed on the mounting frame 1; a slitting knife 52 that aligns the feeding conveyor 3 and the ring-shaped groove 2201 is connected to the reciprocating transmission mechanism 51; installation A front sealing ring 61 is fixedly connected to the frame 1; the front sealing ring 61 is rotatably connected to the fixing ring 25; a jet pipe 64 is fixedly connected to the front sealing ring 61, which corresponds to the number and position of the discharge holes 401 of the discharge conveyor 4; the jet pipe 64 is externally connected to the jet flow conveying equipment, and the jet pipe 64 is connected to the main through hole cavity 2401 of the corresponding sealing plug 24; a sealing ring 41 is fixedly connected to the front port of each discharge hole 401 of the discharge conveyor 4, and the sealing ring 41 is connected to the shaping hole cavity 2301 of the corresponding shaping tube 23, and the sealing ring 41 blocks the side through hole cavity 2302 of the corresponding shaping tube 23.

[0019] like Figure 7 and Figure 8As shown, each shaping tube 23 has several side through-hole cavities 2302 structures surrounding the outside of the shaping cavity 2301, and the side through-hole cavities 2302 are connected to the shaping cavity 2301; each sealing plug 24 has a side sealing plug 2402 structure corresponding to the number and position of the side through-hole cavities 2302, and the side sealing plug 2402 is inserted into the corresponding side through-hole cavities 2302; each sealing plug 24 has a side air groove 2403 structure at the rear end of the side sealing plug 2402 structure that is connected to the corresponding main through-hole cavity 2401.

[0020] like Figure 5 As shown, a suction pipe 62 corresponding to the number and position of the feed holes 301 of the feed conveyor 3 is fixedly connected to the front sealing ring 61. The suction pipe 62 is connected to an external airflow suction device and is connected to the main through hole cavity 2401 of the corresponding sealing plug 24. A flow meter 63 is installed on each suction pipe 62.

[0021] The working steps of a photovoltaic welding strip processing slitting machine according to the present invention are as follows.

[0022] In this embodiment, both the feeding conveyor 3 and the discharging conveyor 4 have three feeding holes 301 and three discharging holes 401, respectively. Therefore, the number of photovoltaic welding strips processed simultaneously in each batch is three. First, the ends of the three photovoltaic welding strips are inserted into the three feeding holes 301 of the feeding conveyor 3, respectively. The feeding conveyor 3 heats the photovoltaic welding strips entering the three feeding holes 301. After being heated, the photovoltaic welding strips become more ductile. The feeding conveyor 3 then transports the photovoltaic welding strips in the feeding holes 301 to the corresponding three fixed points on the rotating drum 22. In the shaping cavity 2301 of the shaping tube 23, the photovoltaic welding strip can be straightened by the shaping cavity 2301 of the shaping tube 23, so that the photovoltaic welding strip forms a straight structure without bending deformation. At the same time, the external airflow suction device continuously performs airflow suction on the sealing plugs 24 corresponding to the three shaping tubes 23, so that the external airflow flows through the side through cavity 2302 of the shaping tube 23, the main through cavity 2401 of the sealing plug 24 and the side sealing plug 2402 and is sucked away through the air extraction pipe 62. At the same time, the flow meter 63 continuously monitors the flow through the air extraction pipe. The airflow at 62 is monitored for flow rate. This continuous airflow can accelerate the cooling speed of the photovoltaic ribbon inside the shaping tube 23. When the feeding conveyor 3 delivers the photovoltaic ribbon into the shaping cavity 2301 of the shaping tube 23 and contacts the sealing plug 24, the main through-hole cavity 2401 of the sealing plug 24 will be blocked by the photovoltaic ribbon. At this time, the external airflow can only flow through the side through-hole cavity 2302 of the shaping tube 23 and the side air groove 2403 of the sealing plug 24, and is sucked away through the extraction pipe 62. Therefore, the flow meter 63 will identify the flow through the extraction pipe. The flow rate of air 62 shows a significant decrease, indicating that the photovoltaic welding ribbon has been transported to the designated position inside the shaping tube 23. The flow meter 63 immediately sends a stop signal to the feeding conveyor 3 through the circuit system, causing the feeding conveyor 3 to stop transporting the photovoltaic welding ribbon. Then, the reciprocating transmission mechanism 51 pushes the slitting knife 52 downward to cut into the annular groove 2201 of the rotating drum 22. The slitting knife 52 cuts the part of the photovoltaic welding ribbon that has entered the shaping tube 23, and obtains a photovoltaic welding ribbon segment of the specified length inside the shaping tube 23.

[0023] When the reciprocating transmission mechanism 51 drives the slitting blade 52 to move upward and reset, the external airflow suction device stops suction. The motor 28 drives the gear 29 to rotate. The gear 29 meshes with the gear ring 27 to drive the rotating drum 22 to rotate counterclockwise by a specified angle from the frontal view angle until the next set of three shaping tubes 23 are respectively aligned with the three feed holes 301 of the feeding conveyor 3. The photovoltaic welding strip segments are then cut into each shaping tube 23 in sequence according to the above steps. After each set of three photovoltaic welding strip segments is cut into the three shaping tubes 23, the motor 28 drives the rotating drum 22 to rotate counterclockwise by a specified angle from the frontal view angle once more. During the rotation of the rotating drum 22 and the shaping tubes 23, the photovoltaic welding strip segments can gradually cool and form within the shaping tubes 23. The plasticity of the cooled photovoltaic welding strip segments is reduced.

[0024] When the rotating drum 22 drives the three shaping tubes 23 to align with the three sealing rings 41 of the discharge conveyor 4, the side through-hole cavity 2302 of the shaping tube 23 is blocked by the sealing ring 41, allowing only the shaping hole cavity 2301 of the shaping tube 23 to connect to the corresponding discharge hole 401 of the discharge conveyor 4. At this time, the jet pipe 64 connects to the main through-hole cavity 2401 of the sealing plug 24 inside the three shaping tubes 23. Then, the external jet flow conveying equipment delivers pressurized airflow to the main through-hole cavity 2401 of the three sealing plugs 24 through the jet pipe 64. The pressurized airflow pushes the photovoltaic welding strip segment into the discharge hole 401 along the shaping hole cavity 2301 of the shaping tube 23 and the sealing ring 41 of the discharge conveyor 4, allowing the photovoltaic welding strip segment to be blown out into the discharge conveyor 4 in a straight structure without bending deformation for feeding.

[0025] When it is necessary to change the cutting length of the photovoltaic welding strip, it is only necessary to control the electric adjusting push rod 26 to move the fixing ring 25 back and forth. At the same time, the fixing ring 25 moves the sealing plug 24 along the inside of the shaping tube 23 in the back and forth direction for adjustment. The length of the part inside the shaping tube 23 that is blocked by the sealing plug 24 is the cutting length of the photovoltaic welding strip.

[0026] Example 2, this example is based on Example 1, such as... Figures 1-9 As shown, a rear sealing ring 65 is fixedly connected to the mounting bracket 1; the rear sealing ring 65 is rotatably connected to the rear side of the rotating drum 22; the rear sealing ring 65 tightly adheres to the rear side of the rotating drum 22 to seal the rear end of the shaping tube 23, and the upper side of the rear sealing ring 65 has a gap structure aligned with the positions of the feeding conveyor 3 and the discharging conveyor 4; a liquid inlet pipe 71 is fixedly connected to the left side of the front sealing ring 61, and the liquid inlet pipe 71 is externally connected to a passivating agent solution conveying device; the liquid inlet pipe 71 is connected to the main through hole cavity 2401 of the three sealing plugs 24 located on the left side of the rotating drum 22; a liquid outlet pipe 72 is fixedly connected to the left side of the rear sealing ring 65, and the liquid outlet pipe 72 is externally connected to a waste liquid suction device, and the liquid outlet pipe 72 is aligned with the liquid inlet pipe 71; the liquid outlet pipe 72 is connected to the shaping hole cavity 2301 and the side through hole cavity 2302 of the three shaping tubes 23 located on the left side of the rotating drum 22.

[0027] In this embodiment, when the rotating drum 22 drives the sealing plug 24 and the shaping tube 23 and the photovoltaic ribbon segment inside to rotate to align between the liquid inlet pipe 71 and the liquid outlet pipe 72, the external passivating agent solution delivery device continuously delivers passivating agent solution to the main through hole cavity 2401 of the sealing plug 24. The passivating agent solution flows from each side air groove 2403 through the shaping hole cavity 2301 and the side through hole cavity 2302 of the corresponding shaping tube 23, allowing the photovoltaic ribbon segment inside the shaping tube 23 to be immersed in the passivating agent solution. The passivating agent solution performs passivation treatment on the cross-sectional structure at both ends of the photovoltaic ribbon segment, avoiding severe oxidation at both ends of the photovoltaic ribbon segment. After the passivating agent solution delivery device stops delivering the passivating agent solution, the passivating agent solution in the shaping tube 23 is recovered into the external waste liquid suction device, ending the passivation treatment of the cross-sectional structure of the photovoltaic ribbon segment.

[0028] Example 3, this example is based on Example 2, such as Figures 1-9 As shown, an air inlet pipe 81 is fixedly connected to the right side of the front sealing ring 61, and the air inlet pipe 81 is connected to a cooling airflow conveying device; the air inlet pipe 81 is connected to the main through hole cavity 2401 of the six sealing plugs 24 located on the right side of the rotating drum 22; an air outlet pipe 82 is fixedly connected to the right side of the rear sealing ring 65, and the air outlet pipe 82 is connected to a waste airflow suction device, and the air outlet pipe 82 is aligned with the air inlet pipe 81; the air outlet pipe 82 is connected to the shaping hole cavity 2301 and the side through hole cavity 2302 of the six shaping tubes 23 located on the right side of the rotating drum 22.

[0029] In this embodiment, when the rotating drum 22 drives the sealing plug 24 and the shaping tube 23 and the photovoltaic welding strip inside them to rotate between the air inlet pipe 81 and the air outlet pipe 82, the external cooling airflow conveying device continuously delivers cooling airflow to the main through hole cavity 2401 of the sealing plug 24. The cooling airflow flows from each side air groove 2403 through the shaping hole cavity 2301 and the side through hole cavity 2302 of the corresponding shaping tube 23, so that the outer surface of the photovoltaic welding strip inside the shaping tube 23 is wrapped in the cooling airflow. The cooling airflow dries the passivating agent solution remaining on the surface of the photovoltaic welding strip. At the same time, the continuously flowing cooling airflow can also accelerate the cooling and shaping process of the photovoltaic welding strip. After the cooling airflow conveying device stops delivering the cooling airflow, the residual passivating agent solution in the shaping tube 23 is recovered into the external waste airflow suction device along with the cooling airflow, thus ending the drying process and accelerated cooling and shaping process of the outer surface of the photovoltaic welding strip.
