[0025] When working, Figure 1-Figure 4As shown, the battery cell to be tested is placed on the top of the support plate 2 by a manipulator or a conveying device, so that one end of the battery cell with the electrode installed is in contact with the rear end surface of the support plate 2; then the first cylinders 6 on the left and right sides of the support plate 2 start to work, and the first cylinders 6 first drive the fixed plate 5 to move upward, so that the ground of the clamping plate 7 is flush with the top surface of the support plate 2, and then the first driving mechanism drives the two first slide plates 3 to move toward each other; until the two clamping plates 7 are in contact with the side walls of the battery cell, at this time the battery cell is located in the center of the support plate 2 and directly below the second slide plate 4; when there is a bulge on the bottom surface of the battery cell, the bottom surface of the battery cell cannot be completely attached to the top surface of the support plate 2, and at this time one end of the battery cell is tilted. When the battery cell is tilted, The clamping plate 7 near one end of the battery cell can be inserted under the battery cell. At this time, the first detection block 8 will move outward relative to the clamping plate 7, and the first detection plate 8 will push the first slider 11 and the first piston 10 to move outward synchronously.

[0029] When working, Figure 6 As shown, when the first limit block 19 moves to the right to cancel the limit on the first rotating shaft 15, the first limit block 19 will push the clamping rod 28 to move to the right synchronously, and the clamping rod 28 will move to a position in contact with the second limit block 20. At this time, the second limit block 20 cannot move, which can ensure that the support plate 2 can be stably flipped to the lower left; the same is true when the second limit block 20 moves to the left, which can ensure that the support plate 2 can be stably flipped to the lower right.

At this time, the first detection block 8 will move outward relative to the clamping plate 7, and the first detection plate 8 will push the first slider 11 and the first piston 10 to move outward synchronously. At this time, the hydraulic oil in the first cylinder 9 will be pressed out, which means that there is a bulge on the bottom surface of the battery cell; when there is no bulge on the bottom surface of the battery cell, the bottom surface of the battery cell can be completely fitted with the support plate 2; at this time, the two clamping plates 7 can clamp the left and right side walls of the battery cell; then the second driving mechanism drives the second slide plate 4 to move downward to the specified position; when there is a bulge on the top surface of the battery cell, the second detection block 12 will be lifted up by the bulge, and at this time the second detection block 12 will drive the second piston 13 in the second cylinder The hydraulic oil in the second detection block 14 will be pressed out, which means that there is a bulge on the top surface of the battery cell; when there is no bulge on the top surface of the battery cell, the second detection block 12 can move downward to fit with the top surface of the battery cell; then the first cylinder 11 drives the fixing plate 5, the clamping plate 7, the first detection block 8, the first cylinder body 9, the first piston 10 and the first slider 11 to move upward synchronously. At this time, the clamping plate 7 will slide upward on the left and right vertical side walls of the battery cell. When the first detection block 8 touches the bulge, the bulge will drive the first detection block 8 to move outward on the clamping plate 7 through the inclined surface set at the top of the first detection block 8. At this time, the hydraulic oil in the first cylinder body 9 is pressed out, and the left side of the battery cell is pressed out.
