[0038] The formation negative pressure suction nozzle alignment mechanism 700 comprises an upper frame 110, an X-axis slide plate 300, a plurality of offset assemblies 400, and a Y-axis slide plate 500. The X-axis slide plate 300 is slidably connected to the upper frame 110. The offset assembly 400 comprises a transition plate 410, an offset slider 420, and a bearing 430. The offset slider 420 is slidably connected to the X-axis slide plate 300. The offset slider 420 is slidably connected to the transition plate 410. The slidable directions of the offset slider 420 and the transition plate 410 are crossed. The Y-axis slide plate 500 is provided with a suction nozzle mounting plate 600. The suction nozzle mounting plate 600 is provided with a plurality of negative pressure suction nozzles 610. The Y-axis slide plate 500 is provided with the offset assembly 400 at each corner.

[0039] Specifically, the sliding direction of the offset slider 420 and the transition plate 410 can be 60, 70, 80, 90 degrees, etc., as long as the offset slider 420 and the transition plate 410 can slide when the Y-axis sliding plate 500 is slightly rotated. When the forming negative pressure suction nozzle alignment mechanism of the utility model is used, the position of the negative pressure suction nozzle 610 on the suction nozzle mounting plate 600 is adjusted in advance, so that the negative pressure suction nozzle 610 on the suction nozzle mounting plate 600 is roughly adapted to the liquid injection hole position of the battery 900 to be formed. In the process of aligning the negative pressure suction nozzle 610 with the liquid injection hole of the battery 900, when it is necessary to adjust the movement of the negative pressure suction nozzle 610 in the X-axis and Y-axis directions driven by the Y-axis sliding plate 500, the positions of the X-axis sliding plate 300 and the Y-axis sliding plate 500 can be moved to realize the position adjustment of the negative pressure suction nozzle 610 in the X-axis and Y-axis directions. When it is necessary to realize the slight adjustment of the negative pressure suction nozzle 610 in the XY plane rotation direction driven by the Y-axis sliding plate 500, the bearing 430 at the corner of the Y-axis sliding plate 500 is operated, and at the same time, each offset slider 420 slides a small distance on the transition plate 410 and the X-axis sliding plate 500, so as to realize the slight rotation of the Y-axis sliding plate 500, which can further drive the movement of the negative pressure suction nozzle 610, and further realize the fine adjustment of the position of the negative pressure suction nozzle 610 on the Y-axis sliding plate 500. In this way, the forming negative pressure suction nozzle alignment mechanism of the utility model can realize the nozzle alignment function of three degrees of freedom in the X, Y axial directions and the XY plane rotation, and improve the accuracy and efficiency of aligning the negative pressure suction nozzle 610 with the liquid injection hole of the battery 900.

Specifically, the X-axis sliding plate 300 is slidably connected to the first guide rail 710 through the first sliding block 730 on the sliding block seat 720. When the X-axis sliding plate 300 is pushed, the X-axis sliding plate 300 drives the offset slider 420, the transition plate 410, the Y-axis sliding plate 500 and the negative pressure suction nozzle 610 to move.
