The support frame 2 spans the support plate 1 and is provided with a horizontal first sliding assembly 3 on the top of the support frame 2. The first sliding assembly 3 includes a slide rail and a drag chain arranged on the top of the support frame 2. The lifting mechanism 4 provides horizontal power through the first sliding assembly to drive the mechanical gripper 41 to feed horizontally. The lifting mechanism 4 provides vertical power to the mechanical gripper 41 to drive the mechanical gripper 41 to move up and down to grab the current collector battery cell 8. The lifting assembly 4 is slidably installed on the first sliding assembly 3, and the bottom of the lifting assembly 4 A mechanical gripper 41 is connected to the support frame 2, and a first positioning plate 21 is arranged at the bottom of the support frame 2 near the loading area. A second sliding component 5 installed in parallel with the first sliding component 3 is arranged on the support plate 1 below the first positioning plate 21, and a second positioning plate 11 located below the first positioning plate 21 is installed on the second sliding component 5. A current collector cell 8 is placed on the first positioning plate 21, and a battery cover plate 9 is placed on the second positioning plate 11. During the process of the mechanical gripper 41 grabbing the composite current collector cell 8, the pole ears 81 reserved for the positive and negative electrodes of the cell are punctured and shaped by the position-adjustable shaping mechanism 6 to prevent the pole ears 81 from sagging. After the shaping is completed, the current collector cell 8 is placed on the battery cover plate 9 and moved to the welding position for welding, thereby improving the welding yield.

[0024] like Figure 3 and Figure 4 As shown, the shaping mechanism 6 includes a third sliding component 61 arranged on the top of the support plate 1, and the two groups of shaping mechanisms 6 are connected by a transverse movement component 60 located at the bottom of the support plate 1. A C-shaped mounting block 64 is arranged on the slider of the third sliding component 61, and the transverse movement component 60 is connected to the slider of the third sliding component 61 through a connecting rod 62. A shaping cylinder 65 is vertically arranged in the mounting block 64, and the output end of the shaping cylinder 65 is connected to a shaping concave plate 67, and a shaping convex plate 68 is connected to the corresponding position of the mounting block 64 above the shaping concave plate 67. The transverse movement component 60 adopts a screw structure, and one end of the connecting rod 62 is installed on the screw through a threaded block. The two groups of shaping mechanisms 6 are symmetrically installed on the transverse movement component 60 through the connecting rod 62, and the threaded rotation directions of the threaded blocks of the two connecting rods are opposite, so that the two groups of shaping mechanisms 6 can achieve synchronous movement in opposite directions or opposite directions, and at the same time, the positive and negative pole ears 81 of the current collector battery cell are shaped and gathered.

[0025] The third sliding component 61 includes at least two sliding rails vertically arranged with the second sliding component 5, a slider is installed on the sliding rail, a connecting plate 63 is installed on the top of the slider, a lifting cylinder 66 is installed on the bottom of the connecting plate 63, and the output end of the lifting cylinder 66 is connected to the mounting block 64 through the connecting plate 63. The lifting cylinder 66 is used to adjust the height of the shaping mechanism to facilitate alignment with the composite current collector battery cell on the mechanical gripper 41.

[0026] like Figure 5 and Figure 6 As shown, buffer springs are provided at both ends of the shaping concave plate 67, at least two grooves are provided on the top of the shaping concave plate 67, and a multi-convex structure 671 is provided in the grooves. A protrusion corresponding to the groove is provided on the shaping convex plate 68, and a corresponding multi-convex countersunk hole 681 is provided on the surface of the protrusion. The multi-convex structure 671 on the shaping concave plate 67 and the corresponding multi-convex countersunk hole 681 on the shaping convex plate 68 gather and shape the multi-layer pole ear 81 to prevent the pole ear from sagging during the feeding process. At the same time, the hole on the pole ear 81 facilitates the positioning with the protrusion structure on the battery cover plate 9.

[0027] The suction cup assemblies 7 are symmetrically arranged on both sides of the second sliding assembly 5, and are connected by a transverse movement assembly 60 located at the bottom of the support plate 1.

[0028] like Figure 7 As shown, the mechanical gripper 41 includes a clamping jaw 411 for clamping the long side of the current collector cell 8 and a clamping jaw 412 for clamping the short side of the current collector cell 8. The clamping jaw 412 is respectively located on both sides of the pole ear 81 reserved for the current collector cell 8, thereby improving the clamping accuracy and ensuring that the current collector cell 8 will not produce deformation, bending and other adverse phenomena during the movement.

[0029] The mechanical gripper 41 is provided with a gathering block 413 on the outer side of the current collector cell 8, which abuts against the pole ear 81.

The shaping mechanisms on both sides move inward until the multi-protrusion structure and the corresponding multi-protrusion countersunk holes move to the shaping area on both sides of the pole ear, and at the same time, the positive and negative pole ears of the battery cell are shaped. After the shaping is completed, the mechanical gripper places the battery cell on the battery cover, ensuring that the shaped holes are aligned with the protrusions on the surface of the battery cover. The suction cup assembly will place a protective sheet on the pole ear, and the feeding mechanism will send the stacked battery cover and current collector battery cell to the welding position for simultaneous welding.
