The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0039] Please refer to Figures 1 to 8 The solar cell wafer distributing device provided by the embodiments of the present application comprises a first conveying unit 1, a second conveying unit 2 and a horizontal moving unit 3. The first conveying unit 1 is used for conveying the cell wafer 4 from a first device along a first direction. The horizontal moving unit 3 is used for moving the cell wafer 4 from the first conveying unit 1 to the second conveying unit 2. The second conveying unit 2 is used for conveying the cell wafer 4 along the first direction. The first conveying unit 1 comprises two first conveying belts 101. The two first conveying belts 101 have a first gap 102 in a second direction. The second direction is perpendicular to the first direction. The second conveying unit 2 is arranged on one side of the first conveying unit 1 in the second direction. The second conveying unit 2 comprises two second conveying belts 201. The two second conveying belts 201 have a second gap 202 in the second direction. The horizontal moving unit 3 comprises a horizontal moving assembly 301, a lifting assembly 302 and a supporting assembly 303. The horizontal moving assembly 301, the lifting assembly 302 and the supporting assembly 303 are sequentially connected. The horizontal moving assembly 301 is used for driving the lifting assembly 302 to move along the second direction, so that the supporting assembly 303 is aligned with the first gap 102 or the second gap 202 in a vertical direction. The lifting assembly 302 is used for driving the supporting assembly 303 to rise or fall, so that the cell wafer 4 is separated from the first conveying unit 1 or the cell wafer 4 of the supporting assembly 303 is placed on the second conveying unit 2. The vertical direction is perpendicular to the first direction and the second direction.

[0040] In the embodiments of the present application, the horizontal moving assembly 301 can drive the lifting assembly 302 to move along the second direction, so that the supporting assembly 303 is aligned with the first gap 102 in the vertical direction, please refer to FIG. 1. Figures 1 to 3 The lifting assembly 302 can drive the supporting assembly 303 aligned with the first gap 102 to rise, so that the cell wafer 4 is lifted to the upper side of the first conveying unit 1 in the vertical direction, and the cell wafer 4 is separated from the first conveying unit 1, please refer to FIG. 2. Figure 4 The horizontal moving assembly 301 can also drive the lifting assembly 302 to move along the second direction, so that the supporting assembly 303 supporting the cell wafer 4 is aligned with the second gap 202 in the vertical direction, please refer to FIG. 3. Figure 5The lifting assembly 302 can also drive the support assembly 303 aligned with the second gap 202 to descend below the second conveying unit 2, so that the battery sheet 4 on the support assembly 303 is placed onto the second conveying unit 2. This embodiment does not need to use suction cups to adsorb the battery sheet 4, which can effectively reduce the risk of battery sheet 4 fragmentation and hidden cracks, and effectively improve the product yield of the battery sheet 4. Moreover, after the support assembly 303 lifts the battery sheet 4 above the first conveying unit 1, the first conveying unit 1 can continue to convey the battery sheet 4, thereby improving the conveying efficiency.

[0041] As an example, please refer to Figure 1 The first conveying unit 1 has a first end 103 and a second end 104 arranged opposite in the first direction, and the battery sheet 4 from the first device is conveyed from the first end 103 of the first conveying unit 1 to the second end 104 of the first conveying unit 1, and the transverse unit 3 is arranged close to the second end 104 of the first conveying unit 1.

Then the lifting assembly 302 drives the support assembly 303 to move upward through the first gap 102 to the second position, and the support assembly 303b in the second position lifts the battery sheet 4 of the second end 104 of the first conveying unit 1 to separate from the first conveying unit 1. Then the transverse assembly 301 drives the lifting assembly 302 and the support assembly 303 carrying the battery sheet 4 to move to the third position along the second direction, and the support assembly 303c in the third position is located above the second conveying unit 2, and the support assembly 303c in the third position is aligned with the second gap 202 in the vertical direction. Then the lifting assembly 302 drives the support assembly 303 to move downward through the second gap 202 to the fourth position, and the support assembly 303d in the fourth position is located below the second conveying unit 2, so that the support assembly 303d in the fourth position is separated from the battery sheet 4, and the battery sheet 4 is placed onto the second conveying unit 2, thereby completing the diversion of one battery sheet 4. Then the transverse assembly 301 can drive the support assembly 303 to move back to the first position along the second direction, and the cycle continues. In this example, after the support assembly 303 lifts the battery sheet 4 to separate from the first conveying unit 1, the first conveying unit 1 can continue to convey the next battery sheet 4 to the second end 104 of the first conveying unit 1, thereby effectively improving the conveying efficiency. For example, please refer to Figure 6 The first conveying unit 1 can continue to convey the next battery sheet 4 to the second end 104 of the first conveying unit 1 before the support assembly 303 moves back to the first position along the second direction, which can improve the conveying efficiency.

The movement precision is high, the supporting assembly 303 can be stably and effectively moved along the second direction, and the risk of cell tab 4 fragmentation and hidden cracks is further reduced.

[0046] It should be noted that in other embodiments, the transverse moving assembly 301 can also have other structures, which can be set according to actual conditions, and details are not described herein.

[0047] In some embodiments, as shown in Figure 3 and Figure 4 , the lifting assembly 302 is a pneumatic cylinder, which includes a cylinder body 3021 and a piston rod 3022 that cooperate with each other. The cylinder body 3021 is fixed to the transverse moving assembly 301, the piston rod 3022 extends from the upper end of the cylinder body 3021, and the supporting assembly 303 is fixed to the piston rod 3022. The piston rod 3022 can extend along the vertical direction, so as to lift the supporting assembly 303 upward, so that the supporting assembly 303 can lift the cell tabs 4 on the first conveying unit 1 upward. The piston rod 3022 can retract along the vertical direction, so as to move the supporting assembly 303 downward, so that the supporting assembly 303 can place the cell tabs 4 on the second conveying unit 2.

[0050] As an embodiment, please refer to Figure 1 , Figure 2 , and Figures 5 to 8 , the width of the support assembly 303 in the second direction is less than the width of the first gap 102 in the second direction, so as to avoid scratching when the support assembly 303 moves in the vertical direction in the first gap 102. Similarly, the width of the support assembly 303 in the second direction is less than the width of the second gap 202 in the second direction, so as to avoid scratching when the support assembly 303 moves in the vertical direction in the second gap 202.
