[0035] Embodiment 1

[0036] like Figures 1 to 4 As shown, the specifications of the battery cell are divided into whole cell, two-piece, three-piece and four-piece, among which the whole cell type corresponds to Figure 1 The structure shown, the bisection type corresponds to Figure 2 The structure shown, the three-piece type corresponds to Figure 3 The structure shown, the four-slice type corresponds to Figure 4 The structure shown.

[0037] like Figures 5 to 7As shown, a feeding device for battery cell welding includes a translational robot arm 3 and a transmission platform 6. The translational robot arm 3 is mounted above the transmission platform 6. The translational robot arm 3 and the transmission platform 6 are arranged in a cross shape. A battery cell material box is also arranged on the side of the transmission platform 6. Among them, the battery cell material box includes a battery cell material box 1 5 and a battery cell material box 2 7. Further, the battery cell material box 1 5 and the battery cell material box 2 7 are symmetrically distributed on both sides of the translational robot arm 3 with the transmission platform 6 as the center. Through the above layout, the space utilization rate can be improved. The battery cell material box 1 5 and the battery cell material box 2 7 are set. When one material box is empty, the other material box can take over the feeding, thereby realizing uninterrupted feeding.

[0038] Since there is no welding strip on the surface of the back-contact cell, the surface is smooth, and stacking them together can easily cause damage to the cell surface. Therefore, when stacking the cells, paper sheets are placed between adjacent cells to separate the two cells. During the cell welding process, two cells need to be welded together, and the paper sheets need to be removed when loading, so that only the cells are transferred.

[0039] Based on the above practical needs, a paper material box is configured next to the battery cell material box, wherein the paper material box includes paper material box 1 4 and paper material box 2 8 , paper material box 1 4 is located next to battery cell material box 1 5 , and paper material box 2 8 is located next to battery cell material box 2 7 .

[0040] like Fig. 9 As shown, the translation robot 3 includes a crossbar 301 and a slider 302. The slider 302 is slidably connected to the crossbar 301. The slider 302 is controlled to move by the main control device of the translation robot 3. This process is a prior art of the module and is not described here. In addition, a suction cup frame 17 driven by the mobile module 19 to move up and down is installed on the slider 302, and a suction cup 18 for adsorbing the battery cell is installed on the suction cup frame 17.

[0041] Furthermore, two suction cup frames 17 are arranged opposite to each other, and the distance between the two suction cup frames 17 is adapted to the distance between adjacent battery sheet boxes and paper sheet boxes.

[0042] Since the surface of the battery cell is generally blue, and the paper placed between two adjacent battery cells is white, a color detection sensor 12 is also installed on the suction cup frame 17 according to the different colors. The detection end of the color detection sensor 12 is downward, which is used to detect the color of the workpiece adsorbed by the suction cup 18. The color detection sensor 12 detects whether the workpiece in the area is a battery cell or a paper sheet, and then controls the slider 302 through the main control device to move it to the corresponding paper sheet material box or battery sheet material box.

[0043] Please refer to Figure 8In order to be suitable for battery cells of different specifications, the battery cell material box includes an adjustment plate 15 and an adjustment plate 2 16 which are detachably mounted on a receiving plate 20, wherein the adjustment plates 2 16 are relatively distributed in multiple groups on the receiving plate 20, each group including two adjustment plates 2 16, which are respectively located at the two ends of the battery cell, and a protrusion is provided on the side of the adjustment plate 2 16 facing the battery cell, and the cross-section of the protrusion and the adjustment plate 2 16 is in a convex shape, and a clamping station is formed between adjacent adjustment plates 2 16 through the protrusion.

[0044] In order to determine the specifications of the battery cells, a plurality of position sensors 11 are arranged below the battery cell material box, and one position sensor 11 corresponds to one clamping position on the receiving plate 20 .

[0045] In addition, a lifting plate 13 is provided on the receiving plate 20, and the lifting plate 13 is driven to move up and down by a telescopic rod 14. Specifically, the telescopic rod 14 is installed on the receiving plate 20, and the telescopic end passes through the receiving plate 20 and is connected to the lifting plate 13. The telescopic rod 14 can be a cylinder, and the lifting plate 13 is driven to move up and down by the movement of the telescopic end of the cylinder.

[0046] Furthermore, a through-beam switch 10 is installed on the receiving plate 20 , and the through-beam switch 10 is used to detect whether there is a workpiece in its detection range. When the through-beam switch 10 detects the workpiece, the moving module 19 drives the suction cup frame 17 to descend, and the suction cup 18 sucks the workpiece.

[0047] Furthermore, a blowing mechanism 9 is arranged on the receiving plate 20 in the battery sheet material box, and two blowing mechanisms 9 are provided, which are respectively located on both sides of the workpiece on the receiving plate 20, and are used to blow air to the workpiece. The blowing mechanism 9 includes a blowing port and a blowing member, and the blowing member can be a structure that can provide wind power, such as a fan or a blower. The wind blown out of the blowing port can blow up the battery sheet, so that the suction cup 18 can be adsorbed and the material can be moved.

[0048] Embodiment 2

[0050] The push plate 204 is driven to move by the transverse cylinder 203 to limit the two ends of the battery cell. A plurality of reserved holes are provided on the base plate 205 for installing the positioning plate 206, and the position of the positioning plate 206 can be adjusted according to the size of the battery cell, so as to facilitate the positioning of the battery cell.

[0051] like Fig.10 , Fig.11 As shown, the vertical cylinder 207 drives the substrate 205 to move up and down. When the transmission platform 6 transports multiple battery cells to the pre-positioning mechanism 2, the vertical cylinder 207 drives the substrate 205 to move upward, so that the positioning plate 206 is located between two adjacent battery cells. Through the transportation of the transmission platform 6, the battery cells continue to move in the transmission direction, and are blocked by the positioning plate 206, so that the battery cells stagnate on the transmission platform 6. At this time, the spacing between adjacent battery cells is adjusted to a preset distance through the mutual cooperation between the transmission platform 6 and the positioning plate 206. After the pre-positioning operation is completed, the vertical cylinder 207 drives the substrate 205 to move downward, so that the positioning plate 206 is located below the transmission platform 6, so that the pre-positioned battery cells are transferred to the next station.
