[0049] In this embodiment, the X-axis direction is the left and right sides of the clamp, and the Y-axis direction is the front and back sides of the clamp, that is, the front and back sides of the battery cell 1.

[0050] The fixture of the present utility model is provided with a positioning base plate 10 and a locking member 3 to lock the top and bottom of the battery cell 1, that is, locking in the vertical direction and partial locking in the horizontal direction. The positioning base plate 10 is the bottom of the fixture, and the bottom of the battery cell 1 is placed on the positioning base plate 10. Rotatable locking members 3 are provided at the top ends of both ends of the battery cell 1. The locking member 3 can swing 90 degrees clockwise or counterclockwise to release the top ends of both ends of the battery cell 1; the connecting end of the locking member 3 is movably connected to the arc-shaped groove at the lower end of the upper locking push rod 5 through a connecting shaft. The arc-shaped groove is arranged in an L shape, and the connecting shaft can slide in the arc-shaped groove. At the same time, the upper locking push rod 5 can move up and down at both ends of the fixture, that is, move up and down on both sides of the battery cell 1. When the upper locking push rod 5 descends, it can drive the locking member 3 to flip so as to release the battery cell 1. Similarly, when the upper locking push rod 5 ascends, it drives the locking member 3 to flip to close and lock the battery cell 1. There are two upper locking push rods 5 on the same side of the battery cell 1. The above is the first upper locking push rod 5, and the other upper locking push rod 5 is movably connected to the clamping block 32 and can be connected through a movable member. When the other upper locking push rod 5 descends, it drives the clamping block 32 to move away from both sides of the battery cell 1, thereby releasing the battery cell 1. The clamping groove 321 of the clamping block 32 is adapted to the left and right ends of the battery cell 1. The clamping block 32 clamping the left and right ends of the battery cell 1 is used to limit the positions of the left and right sides of the battery cell 1. In this embodiment, the two upper locking push rods 5 on the same side are arranged one above the other and move on the same slide rail. The upper upper locking push rod 5 can drive the locking member 3, and the lower upper locking push rod 5 can drive the clamping block 32.

The pressing and lifting member 21 can be selected as a cylinder;

[0051] The side correction assembly can limit and support the front and rear end faces of the battery cell 1. In this embodiment, each correction mechanism 6 includes at least two correction push arms 61 arranged side by side. Each correction push arm 61 is adjusted independently in the X-axis direction, and the two correction push arms 61 are adjusted to the same height by the Y-axis moving structure 63, so as to adjust the clamping positions of the front and rear end faces of the battery cell 1. The correction push arm 61 of this embodiment is trapezoidally arranged. A space is provided between the two side-by-side correction push arms 61 to ensure the installation of the detection element 9, and the trapezoidal arrangement improves the supporting force of the correction push arm 61.

[0052] The detection element 9 is used to detect the position of the battery cell 1. At least two pressing plate 2 assemblies are provided at the top of the bracket 7, and at least two fixtures, at least two locking assemblies and at least two side correction assemblies are provided below the bracket 7. This embodiment has the functions of locking and unlocking, stable press-fitting and high working efficiency. In addition, a double-station can be set, with two fixtures, that is, each fixture corresponds to a locking assembly, a pressing plate 2 assembly and a side correction assembly. Setting a double-station can improve the press-fitting and positioning efficiency. The locking pull member 4 can be installed on the support guide rod 71 through the installation structure and the height of the locking pull member 4 can be controlled according to the actual situation.

[0053] When the locking pull piece 4 descends, the corresponding upper locking push rod 5 can descend by means of other driving elements or manually, etc., so as to drive the locking piece 3 to turn over. When the locking pull piece 4 is held at the highest position to abut against the upper end of the upper locking push rod 5, the downward sliding of the upper locking push rod 5 is avoided, so as to keep the control locking piece 3 pressing and limiting the battery cell 1. Both the locking pull piece 4 and the upper locking push rod 5 are arranged in an L shape, so the two are buckled with each other in an inverted hook shape to lock the locking piece 3 and prevent the locking piece 3 from turning over and loosening. In addition, the calibration push arm 61 and the pressing plate 2 can cooperate with other sensors to detect the end face pressure of the battery cell.
