A first clamping member 297a is provided on the side of the first common plate body facing away from the second base 220 and a second clamping member 297b is provided on the side of the second common plate body facing away from the second base 220.

second clamping assemblies

297a and 297b, respectively, are located on opposite sides of sliding seat 292 with respect to attachment rail 201 a. An included angle exists between the direction of the clamping adjustment mechanism 297 for clamping the battery cell and the direction of the clamping positioning mechanism 204 for clamping the battery cell, namely, an included angle exists between the direction of the second clamping assembly 297b and the first clamping assembly 297a for clamping the battery cell together and the direction of the clamping positioning mechanism 204 for clamping the battery cell.

Due to the fact that the first screw joint part and the second screw joint part are in opposite screw directions, when the hand wheel 294a drives the adjusting screw rod 294b to rotate in a positive direction, the second clamping component 297b and the first clamping component 297a move towards directions close to each other, and the second clamping component 297b and the first clamping component 297a clamp the electric core together; when the hand wheel 294a drives the adjusting screw 294b to rotate in the opposite direction, the second clamping assembly 297b and the first clamping assembly 297a move away from each other, and the second clamping assembly 297b and the first clamping assembly 297a release the battery cell together. In this manner, the gap between the first and

When the first clamping plate 2978 and the second clamping plate 2979 clamp the battery cell, the clamping and positioning mechanism 204 moves to a position corresponding to the positioning device 290 along with the sliding seat 292 relative to the second base 220, and the clamping and positioning mechanism 204 clamps and acts on the battery cell. After the clamping and positioning mechanism 204 clamps the battery cell, the first clamping plate 2978 moves towards the direction away from the second clamping plate 2979, so that a better positioning clamp for the battery cell is realized on the battery cell, and the positioning and clamping accuracy of the battery cell is improved. In this embodiment, the direction in which the clamping adjustment mechanism 297 clamps the battery cell is a first direction, the direction in which the clamping positioning mechanism 204 clamps the battery cell is a second direction, the first direction is perpendicular to the second direction, and the first direction and the second direction are both perpendicular to the extending direction of the connection guide rail 201a, so that the first clamping plate 2978 and the second clamping plate 2979 jointly perform horizontal pre-light-pressing clamping positioning on the battery cell, so as to adjust the battery cell to a predetermined position first, and make the clamping positioning mechanism 204 perform longitudinal heavy-pressing clamping on the battery cell, and the problem that the clamping positioning of the battery cell is not in place can be avoided by the clamping positioning in two different directions, and the positioning and clamping accuracy of the battery cell is improved.

The second clamping plate 2979 is slidably disposed on the second common plate main body, so that the second driving source 2977 drives the second clamping plate 2979 to move more smoothly relative to the second common plate main body. In order to enable the first clamping plate 2978 and the second clamping plate 2979 to better clamp the battery cell, in one embodiment, the first clamping plate 2978 and the second clamping plate 2979 are arranged in parallel and opposite, and the first clamping plate 2978 and the second clamping plate 2979 move towards the direction close to or away from each other, so that the first clamping plate 2978 and the second clamping plate 2979 better clamp the battery cell.
