[0021] The utility model is described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 to Figure 2As shown, a battery cell tab regularization mechanism of the utility model comprises a base frame 1, a movable frame 2 movably arranged on the base frame 1, a driver 3 for driving the movable frame 2 to move relative to the base frame 1, and a shaping device 4 movably arranged on the movable frame 2, wherein a plurality of shaping devices 4 are provided and are spaced apart along the length direction of the movable frame 2, the shaping device 4 is provided with a first slider 5, the movable frame 2 is provided with a first guide rail 6 slidably connected to the first slider 5, a positioning piece 7 is provided on the outer side of the shaping device 4, the positioning piece 7 is provided with a positioning hole 71, and the movable frame 2 is provided with a positioning groove 8 used in conjunction with the positioning piece 7.

[0023] During operation, a multi-axis robot from the outside is used to pick up multiple battery cells so that the two pole ears of each battery cell are fully exposed. Since multiple shaping devices 4 are arranged at intervals along the length direction of the movable frame 2, the shaping device 4 slides along the first guide rail 6 through the first slider 5 to adjust the working position of the shaping device 4 accordingly. The shaping device 4 uses the positioning piece 7 to cooperate with the external screw to insert the external screw, so that the external screw passes through the positioning piece 7 and is fixed in the positioning groove 8 accordingly, thereby effectively fixing the spacing position between every two shaping devices 4, and the multiple battery cells are driven to approach the shaping device 4 through the external multi-axis robot. Then the driver 3 drives the movable frame 2 to move upward relative to the base frame 1, so that each battery cell is conveniently inserted between every two shaping devices 4, and every two shaping devices 4 are used to synchronously clamp the two pole ears of each battery cell, and the appropriate clamping force is controlled. It is not advisable to clamp the pole ears too tightly or too loosely. Finally, the external multi-axis robot drives the multiple battery cells to move upward, so that the multiple pole ears are pulled upward from the multiple shaping devices 4, ensuring that the pole ears are completely flattened and stretched with good flatness. The utility model realizes the automatic leveling work of multiple tabs synchronously, facilitates the position adjustment, meets the needs of large-scale efficient processing, and improves the work efficiency and work quality.

Specifically, the bearing seat 43 is installed on the top of the clamping cylinder 42, which effectively improves the bearing support stability. The two clamping jaws 45 are movably arranged in the bearing seat 43. The two clamping jaws 45 protrude into the bearing seat 43 and are driven by the clamping jaw cylinder 42 to move closer to or away from each other relative to the bearing plate 44. The bearing seat 43 with an internal hollow structure facilitates the opening or closing telescopic action of the two clamping jaws 45. When the pole ear is inserted between the two clamping jaws 45, the pole ear is placed against the bearing plate 44. Under the drive of the clamping jaw cylinder 42, the distance between the two clamping jaws 45 gradually decreases to clamp the pole ear, and the pole ear can also be flattened.
