[0002] The photovoltaic cell stringing process is a manufacturing process in which unit sheet materials obtained by scribing battery wafers are connected in series through welding tapes. To ensure the continuous progress of the photovoltaic cell stringing process, in the prior art, unit sheet materials are generally conveyed to a welding device through a conveyor line. Specifically, after the battery wafers undergo scribing operations, a battery wafer handling device transports the scribed battery wafers to the conveyor line. At this time, the battery wafer handling device transports two unit sheet materials obtained by scribing a single battery wafer.

[0003] As described above, since all unit sheet materials need to be placed on the conveyor line in the same direction and angle, and in the direction perpendicular to the conveying direction of the conveyor line, the relative positions of all unit sheet materials with respect to the conveyor line need to be kept consistent.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0029] This embodiment provides a battery cell transfer device, which includes a conveyor line and a battery cell handling device. The battery cell handling device is used to handle all the unit sheets formed by scribing the battery cell, so as to place all the unit sheets formed by scribing the battery cell on the conveyor line in a preset arrangement posture, thereby ensuring that all the unit sheets are placed on the conveyor line in the same direction and angle, and in the direction perpendicular to the conveying direction of the conveyor line, the relative positions of all the unit sheets and the conveyor line are kept consistent.

[0030] Based on the above, please refer to Figures 1 to 3, in this embodiment, the cell handling device includes an adsorption mechanism 210 and a transfer mechanism 220. Among them, the adsorption mechanism 210 is configured to suck the sliced cells 100, that is, the adsorption mechanism 210 can suck two unit sheets obtained by slicing a single cell 100 at the same time. The transfer mechanism 220 includes a moving module, and the moving module includes a first driving module 2211 and a second driving module 2212. The first driving module 2211 is configured to drive the adsorption mechanism 210 to move horizontally, and the second driving module 2212 is configured to drive the adsorption mechanism 210 to move vertically, so that the adsorption mechanism 210 can suck the sliced cells 100 at the slicing station and transport them to the loading station of the conveyor line. Moreover, it can also place all the unit sheets formed by slicing the cell 100 on the conveyor line.

[0031] Based on the above, in this embodiment, the adsorption mechanism 210 includes a first suction cup 211 and a second suction cup 212. The first suction cup 211 and the second suction cup 212 can respectively suck the first unit sheet 110 and the second unit sheet 120 formed by slicing the cell 100. In addition, the transfer mechanism 220 further includes a pose adjustment module 222, and the pose adjustment module 222 can adjust the position of the second suction cup 212, thereby adjusting the pose of the second unit sheet 120, so that the first unit sheet 110 and the second unit sheet 120 can be in a preset arrangement pose, that is, the pose adjustment module 222 can adjust the relative pose of the first unit sheet 110 and the second unit sheet 120 sucked by the adsorption mechanism 210 during the movement of the adsorption mechanism 210.

[0032] Specifically, after the slicing operation, the first unit sheet 110 and the second unit sheet 120 are mirror-symmetrical. Specifically, the first unit sheet 110 and the second unit sheet 120 are arranged in a row. The first suction cup 211 and the second suction cup 212 can respectively suck the first unit sheet 110 and the second unit sheet 120. In this embodiment, the position of the second suction cup 212 can be adjusted by the pose adjustment module 222 so that the second unit sheet 120 and the first unit sheet 110 are arranged in a line, and the crack at the edge of the second unit sheet 120 and the crack at the edge of the first unit sheet 110 are on the same straight line. After that, the first unit sheet 110 and the second unit sheet 120 can be placed on the conveyor line in the same direction and angle, and in the direction perpendicular to the conveying direction of the conveyor line, the relative positions of the first unit sheet 110 and the second unit sheet 120 with respect to the conveyor line are kept consistent.

[0033] As described above, in this embodiment, the adsorption mechanism 210 sucks the sliced battery cells 100, and synchronously transports the first unit sheet 110 and the second unit sheet 120 formed by slicing the battery cells 100 to the conveyor line. Moreover, in this embodiment, the pose adjustment module 222 adjusts the relative pose of the first unit sheet 110 and the second unit sheet 120 sucked by the adsorption mechanism 210 during the movement of the adsorption mechanism 210, so that the sucked first unit sheet 110 and the second unit sheet 120 can be placed on the conveyor line in a preset arrangement posture. That is, in this embodiment, it is not necessary to regularize the unit sheets before sucking the battery cells 100, but to regularize the unit sheets during the transportation process, which can save time and thus improve the production efficiency of the battery string.

[0034] Further, the transfer mechanism 220 further includes a first mounting frame 223. The first driving module 2211 can drive the first mounting frame 223 to move in the horizontal direction, and the second driving module 2212 can drive the first mounting frame 223 to move in the vertical direction. The first suction cup 211 is fixedly connected to the first mounting frame 223, and the second suction cup 212 is rotatably connected to the first mounting frame 223 through a rotating shaft 2221. The axis of the rotating shaft 2221 extends in the vertical direction. The pose adjustment module 222 includes a third driving module 2222, which is configured to drive the second suction cup 212 to rotate around the axis of the rotating shaft 2221, and make the second suction cup 212 have a first working position spaced from the first suction cup 211 in a first horizontal direction, and a second working position spaced from the first suction cup 211 in a second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. Specifically, when the second suction cup 212 is in the first working position, the second suction cup 212 and the first suction cup 211 can correspond to the first unit sheet 110 and the second unit sheet 120 to be sucked one by one. The third driving module 2222 can drive the second suction cup 212 to rotate, thereby driving the second unit sheet 120 to rotate 180°, and further causing the second suction cup 212 to switch from the first working position to the second working position, and driving the second unit sheet 120 to rotate to be arranged in a row with the first unit sheet 110, and the crack at the edge of the second unit sheet 120 and the crack at the edge of the first unit sheet 110 are on the same straight line.

[0035] In addition, the first suction cup 211 includes a plurality of first suction nozzles 2111, and the second suction cup 212 includes a plurality of second suction nozzles 2121, so that the first suction cup 211 and the second suction cup 212 can respectively and stably suck the first unit sheet 110 and the second unit sheet 120.

[0036] Moreover, in this embodiment, a plurality of first suction nozzles 2111 and a plurality of second suction nozzles 2121 are both arranged in a matrix, so that the first suction cup 211 and the second suction cup 212 can respectively and stably suck the first unit sheet 110 and the second unit sheet 120.

[0037] As described above, when the second suction cup 212 is in the first working position, a plurality of first suction nozzles 2111 and a plurality of second suction nozzles 2121 are arranged axially symmetrically, and correspond one by one to the first unit sheet 110 and the second unit sheet 120 to be sucked. The symmetry axis a of the plurality of first suction nozzles 2111 and the plurality of second suction nozzles 2121 extends along the second horizontal direction. After the first suction cup 211 and the second suction cup 212 respectively suck the first unit sheet 110 and the second unit sheet 120, the joint 130 of the first unit sheet 110 and the second unit sheet 120 coincides with the symmetry axis a mentioned above. In addition, the rotating shaft 2221 mentioned above is spaced from the first suction cup 211 along the second horizontal direction, and the axis of the rotating shaft 2221 intersects the symmetry axis a mentioned above. When the third driving module 2222 drives the second suction cup 212 to rotate 180° around the axis of the rotating shaft 2221, the second suction cup 212 is switched from the first working position to the second working position. At the same time, the second unit sheet 120 rotates to be arranged in a row with the first unit sheet 110, and the crack at the edge of the second unit sheet 120 and the crack at the edge of the first unit sheet 110 are located on the same straight line.

[0038] Moreover, since the rotating shaft 2221 is spaced from the first suction cup 211 along the second horizontal direction, and the axis of the rotating shaft 2221 intersects the symmetry axis a, during the rotation process, the second unit sheet 120 will not interfere with the first unit sheet 110.

[0039] It should be noted that the first suction cup 211 further includes a first mounting plate 2112. The first mounting plate 2112 is fixedly connected to the first mounting bracket 223. A plurality of first suction nozzles 2111 are all mounted on the first mounting plate 2112. The second suction cup 212 further includes a second mounting plate 2122. The second mounting plate 2122 is rotatably connected to the first mounting bracket 223 through the rotating shaft 2221. A plurality of second suction nozzles 2121 are all mounted on the second mounting plate 2122.

[0040] In addition, in addition to the first mounting frame 223, the transfer mechanism 220 also includes a second mounting frame 224. The first mounting frame 223 is slidably connected to the second mounting frame 224 in the vertical direction. The second driving module 2212 is installed on the second mounting frame 224 and can drive the first mounting frame 223 to move in the vertical direction. The first driving module 2211 can drive the second mounting frame 224 to move in the horizontal direction, so that the adsorption mechanism 210 can absorb the first unit sheet 110 and the second unit sheet 120 from the dicing station and transport them to the loading station of the conveyor line. Moreover, the first unit sheet 110 and the second unit sheet 120 can also be placed on the conveyor line.

[0041] It is worth noting that in this embodiment, the first drive module 2211 and the second drive module 2212 are both motor screw modules. Of course, in other optional embodiments, the first drive module 2211 and the second drive module 2212 can also be other linear drive structures such as cylinders or KK modules, and this embodiment does not impose specific restrictions on this.

[0042] In addition, it should be noted that in other optional embodiments, the first mounting frame 223 may be slidably connected to the second mounting frame 224 in the horizontal direction, and the first driving module 2211 may be installed on the second mounting frame 224, and the first driving module 2211 may directly drive the first mounting frame 223 to move in the horizontal direction, while the second driving module 2212 may be used to drive the second mounting frame 224 to move in the vertical direction. This embodiment does not impose any specific restrictions on this.

[0043] Furthermore, the third driving module 2222 is installed on the first mounting frame 223, and the posture adjustment module 222 also includes a transmission belt 2224. The third driving module 2222 is connected to the rotating shaft 2221 through the transmission belt 2224, so as to drive the second suction cup 212 to rotate around the axis of the rotating shaft 2221.

[0044] It can be understood that in this embodiment, the third drive module 2222 is a motor. Of course, in other optional embodiments, the third drive module 2222 can also be selected as a rotary cylinder or other rotary drive structure. Moreover, the third drive module 2222 can also be configured to be directly connected to the rotating shaft 2221 in transmission. This embodiment does not impose any specific restrictions on this.

[0045] Further, the pose adjustment module 222 further includes a position detector 2223 configured to detect the position of the second suction cup 212, so as to ensure that the first suction cup 211 and the second suction cup 212 rotate precisely between the first working position and the second working position. Thus, on the one hand, the first suction cup 211 and the second suction cup 212 can precisely suck the first unit sheet 110 and the second unit sheet 120, and on the other hand, the first unit sheet 110 and the second unit sheet 120 can be precisely adjusted to a preset arrangement posture.

[0046] It can be understood that in this embodiment, the position detector 2223 is a photoelectric sensor. Of course, in other alternative embodiments, the position detector 2223 can also be a grating sensor or a vision detection structure, etc. This embodiment does not make specific limitations in this regard.
