[0027] As Figure 7 and Figure 8As shown, each of the shaping tubes 23 is provided with a plurality of side through hole cavities 2302 around the outside of the shaping hole cavities 2301, and the side through hole cavities 2302 are connected to the shaping hole cavities 2301; each of the sealing plugs 24 is provided with side sealing plug 2402 structures corresponding in number and position to the side through hole cavities 2302, and the side sealing plug 2402 structures are inserted into the corresponding side through hole cavities 2302; the rear end of each of the side sealing plug 2402 structures of the sealing plug 24 is provided with a side air groove 2403 structure connected to the corresponding main through hole cavity 2401.

[0029] The working steps of the photovoltaic welding strip processing slitting machine are as follows.

[0030] The number of feeding holes 301 of the feeding conveyor 3 and the number of discharging holes 401 of the discharging conveyor 4 are both three in this embodiment, so the number of photovoltaic welding strips simultaneously processed in each batch is three. First, the ends of the three photovoltaic welding strips are respectively inserted into the three feeding holes 301 of the feeding conveyor 3. The feeding conveyor 3 performs heating treatment on the photovoltaic welding strips entering the three feeding holes 301. The photovoltaic welding strips can be enhanced in plasticity after being heated. The feeding conveyor 3 respectively conveys the photovoltaic welding strips in the feeding holes 301 to the corresponding three shaping hole cavities 2301 of the shaping tubes 23 on the rotating drum 22. The photovoltaic welding strips can be corrected by the shaping hole cavities 2301 of the shaping tubes 23, so that the photovoltaic welding strips form a straight structure without bending deformation. At the same time, the external air flow suction device continuously performs air flow suction work on the corresponding sealing plugs 24 of the three shaping tubes 23. The external air flow passes through the side through hole cavities 2302 of the shaping tubes 23, the main through hole cavities 2401 and the side sealing plugs 2402 of the sealing plugs 24 in sequence, is sucked away through the air suction pipe 62, and the flow monitoring meter 63 continuously performs flow monitoring work on the air flow passing through the air suction pipe 62. The continuously flowing air flow can accelerate the cooling speed of the photovoltaic welding strips in the shaping tubes 23. When the feeding conveyor 3 conveys the photovoltaic welding strips to the inside of the shaping hole cavities 2301 of the shaping tubes 23 and contacts the sealing plugs 24, the main through hole cavities 2401 of the sealing plugs 24 will be blocked by the photovoltaic welding strips. At this time, the external air flow can only pass through the side through hole cavities 2302 of the shaping tubes 23 and the side air grooves 2403 of the sealing plugs 24 to flow through the air suction pipe 62 and be sucked away. Therefore, the flow monitoring meter 63 will identify that the flow of the air flow passing through the air suction pipe 62 has decreased significantly, indicating that the photovoltaic welding strips have been conveyed to the specified position inside the shaping tubes 23. The flow monitoring meter 63 feeds back a stop signal to the feeding conveyor 3 in the first time through the circuit system, so that the feeding conveyor 3 stops conveying the photovoltaic welding strips. Then the reciprocating transmission mechanism 51 pushes the slitting knife 52 to cut down into the annular cutting groove 2201 of the rotating drum 22, and the slitting knife 52 cuts the photovoltaic welding strips into segments at the part inside the shaping tubes 23, so as to obtain photovoltaic welding strip segments of a specified length in the shaping tubes 23.

[0031] When the reciprocating transmission mechanism 51 drives the slitting knife 52 to move upward and reset, the external air flow suction device stops the suction work. The motor 28 drives the gear 29 to rotate, the gear 29 engages with the gear ring 27 to drive the rotating drum 22 to rotate counterclockwise at a specified angle at a viewing angle, until the next three shaping tubes 23 are respectively aligned with the three feeding holes 301 of the feeding conveyor 3. Then the photovoltaic welding strip segments are cut into the respective shaping tubes 23 in sequence according to the above steps. After the three photovoltaic welding strip segments are respectively cut into the three shaping tubes 23, the motor 28 drives the rotating drum 22 to rotate counterclockwise at a specified angle at a viewing angle again. During the rotation of the rotating drum 22 driving the shaping tubes 23, the photovoltaic welding strip segments can gradually complete the cooling and forming in the shaping tubes 23. The cooled photovoltaic welding strip segments can be reduced in plasticity.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.
