[0026] Example:

[0027] In a first aspect, embodiments of this application provide a non-contact solar cell correction mechanism, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, it includes an offset correction component 1, an angle correction component 2, a transmission component 3, and a detection component 4. The transmission component 3 is connected to the offset correction component 1. The angle correction component 2 is disposed between the offset correction component 1 and the transmission component 3. The angle correction component 2 moves along a direction perpendicular to the transmission component 3 under the drive of the offset correction component 1. The transmission component 3 includes a transmission track 301. The angle correction component 2 extends through the transmission plane of the transmission track 301 to contact the battery cell and drive the battery cell to rotate. The detection component 4 is correspondingly disposed with the transmission track 301 and is used to detect whether the battery cell has been transmitted to the correct position. The offset correction component 1 and the angle correction component 2 correct the position of the battery cell that has not been transmitted to the correct position according to the detection result of the detection component 4.

[0028] The non-contact solar cell correction mechanism described in this application includes an offset correction component 1, an angle correction component 2, a transmission component 3, and a detection component 4. During the transmission of the solar cell, based on the detection results of the detection component 4, the offset correction component 1 and the angle correction component 2 correct the position of the solar cell carried on the transmission component 3. This ensures that subsequent transmission steps can proceed smoothly while avoiding damage to the solar cell caused by the correction operation, preventing the risk of microcracks or edge breakage of the solar cell, and improving the yield of the solar cell. Specifically, when the detection component 4 detects that the battery cell is not properly transmitted on the transmission component 3 and needs to be corrected, the offset correction component 1 can correct the positional offset of the battery cell without contacting it by moving the angle correction component 2 and the transmission component 3 together in a direction perpendicular to the transmission direction of the transmission component 3. The angle correction component 2 passes through the transmission plane of the transmission track 301 and rotates the battery cell on the transmission track 301 by contacting the surface area of ​​the battery cell, so that the angle correction component 2 can correct the angle deflection of the battery cell without contacting the edge area of ​​the battery cell.

[0029] Optionally, the offset correction component 1 includes a first rotary drive 101, a transmission rod 102 driven by the first rotary drive 101, and a first carrier plate 103 connected to the transmission rod 102; the first carrier plate 103 moves along the axial direction of the transmission rod 102; the angle correction component 2 is disposed on the first carrier plate 103, and the transmission component 3 is connected to the first carrier plate 103 through a first support 104.

[0030] In some embodiments, the transmission rod 102 is a threaded rod, and the first carrier plate 103 is threadedly connected to the transmission rod 102 and moves along the axial direction of the transmission rod 102.

[0031] In use, the first rotary drive 101 drives the transmission rod 102 to rotate, thereby causing the first carrier plate 103, which is threadedly connected to the transmission rod 102, to move along the axial direction of the transmission rod 102. This causes the angle correction component 2 and the transmission component 3 to move in a direction perpendicular to the transmission direction of the transmission component 3, thereby causing the battery cell disposed on the transmission component 3 to shift along the axial direction of the transmission rod 102 to correct the positional shift of the battery cell.

[0032] Specifically, the transmission rod 102 is a transmission lead screw; the first carrier plate 103 is threadedly connected to the transmission lead screw, which improves the stability of the movement of the first carrier plate 103 and the offset control accuracy, thereby improving the stability of the movement and the movement control accuracy of the angle correction component 2 connected to the first carrier plate 103.

[0033] Optionally, the angle correction assembly 2 includes a second rotary drive 201 disposed on the first carrier plate 103, a second carrier plate 202 disposed at the output end of the second rotary drive 201, a lifting drive 203 disposed on the second carrier plate 202, and a lifting rod 204 disposed at the output end of the lifting drive 203. The second rotary drive 201 is a DD motor.

[0034] Optionally, a third carrier plate 302 is provided on the transmission track 301. The third carrier plate 302 is used to carry the battery cells. The third carrier plate 302 moves along the transmission direction of the transmission track 301 under the drive of the transmission track 301. The lifting rod 204 can pass through the third carrier plate 302. The third carrier plate 302 has a hole structure 3021 for the lifting rod 204 to pass through. The diameter of the hole structure 3021 is larger than the cross-sectional area of ​​the lifting rod 204 to facilitate the passage of the lifting rod 204, reduce the precision adjustment of the lifting rod 204's passage, and facilitate operation. It can be understood that the overall surface area of ​​the third carrier plate 302 is greater than or equal to the surface area of ​​the battery cells. Optionally, the transmission track 301 can be a linear track or a conveyor belt.

[0035] Optionally, a fourth carrier plate 205 is provided at the top of the lifting rod 204. The surface area of ​​the fourth carrier plate 205 is larger than the cross-sectional area of ​​the lifting rod 204, thereby increasing the contact area between the lifting rod 204 and the battery cell and avoiding stress concentration that could damage the battery cell.

[0036] Optionally, the fourth carrier plate 205 is provided with suction holes 206, which are used to adsorb the battery cells, so that the lifting rod 204 provides stable support for the battery cells. In use, the lifting drive 203 drives the lifting rod 204 to extend until it contacts the surface of the battery cell and provides support for the battery cell. The second rotation drive 201 drives the second carrier plate 202 connected to its output end to rotate, thereby causing the lifting drive 203 and the lifting rod 204 to rotate synchronously. This causes the battery cell to rotate around the axis of the lifting rod 204 under the drive of the lifting rod 204, so as to correct the angular deflection of the battery cell. It is understood that the suction holes 206 are connected to the air extraction device through pipes.

[0037] The non-contact solar cell correction mechanism also includes a platform 5 and a frame 6. The offset correction component 1, the angle correction component 2 and the detection component 4 are located in the area enclosed by the frame 6 and the platform 5. The offset correction component 1 is located on the platform 5, and the angle correction component 2 and the transmission component 3 are located on the side of the offset correction component 1 away from the platform 5.

[0038] The detection component 4 is a photoelectric sensor component; the detection component 4 includes a plurality of reflective photoelectric sensors 401 mounted on the frame 6 and a reflector 402 mounted on the platform 5. The emitting end of the reflective photoelectric sensors 401 is positioned facing the side of the transmission component 3 that carries the battery cell. The reflective photoelectric sensors 401 are distributed circumferentially along the battery cell to form a positioning detection area. In use, the light emitted by the reflective photoelectric sensors 401 is reflected by the reflector 402. The reflective photoelectric sensors 401 detect whether the battery cell has been transmitted to the correct position based on the reception of the reflected light. Then, the offset correction component 1 and the angle correction component 2 correct the position of the battery cell based on the detection result of the detection component 4.

[0039] In this embodiment, the reflective photoelectric sensors 401 are symmetrically arranged on both sides of the battery cell along the transmission direction of the transmission component 3; the number of reflective photoelectric sensors 401 is at least four; at least four reflective photoelectric sensors 401 are arranged corresponding to the four corner areas of the battery cell; see [link to previous embodiment]. Figure 3 As shown, when the number of reflective photoelectric sensors 401 is four, the reflective photoelectric sensors 401 are set in the four corner areas of the battery cell. When the battery cell is moved into place, the distance between the light emitted by the reflective photoelectric sensor 401 and the edge of the battery cell is 0.1-4cm, so that the transmission position of the battery cell on the transmission assembly 3 can be within the allowable error range.

[0040] Secondly, this application provides a solar cell transport device, which includes the non-contact solar cell correction mechanism described above. The solar cell transport device includes the non-contact solar cell correction mechanism, which corrects the position of solar cells that are not properly transported without contacting the edge area of ​​the solar cell, thus preventing the edge of the solar cell from being stressed and causing microcracks or chipping, while ensuring smooth transport of the solar cell.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
