In the embodiment shown in fig. 8, the foam pressing mechanisms 3 are symmetrically arranged with respect to a center line of the foam pressing rod 34, and the foam pressing mechanisms 3 include:
two third supporting seats 31 are provided and fixedly connected to the supporting frame 1;

The first detection device 35 is fixedly connected to the fourth support seat 32, and is configured to detect whether each to-be-clamped battery cell 8 is horizontally level; the reason why the first detecting device 35 is to be provided to detect whether each of the battery cells 8 to be clamped is level, i.e. equal in height, is that: when the battery cell 8 is clamped into the groove of the foam, generally, in order to avoid the battery cell 8 from moving in the groove, the battery cell 8 and the groove generally adopt transition fit or interference fit, and therefore, when the battery cell 8 is inserted into the groove, it may happen that the battery cell 8 is not inserted in place, so that the battery cell 8 is tilted, that is, the rest of the battery cells 8 inserted in place are protruded in the height direction, and therefore when the clamping mechanism 4 clamps the battery cell 8, the battery cell which is not inserted in place may interfere with and collide with the clamping mechanism 4 due to the protrusion in the height direction, and the battery cell 8 or the clamp of the utility model is damaged, thereby causing potential safety hazards.
In a specific embodiment, the first detecting device 35 employs a correlation sensor, and there are two corresponding edges on the top end of the battery cell 8, which are used because: when the battery cell 8 is inserted in place, one side of the top end of the battery cell may be high, and the other side of the battery cell may be low, if only one battery cell is used, the height detected by the side which is possibly low is that the surface of the battery cell is inserted in place, and is equal to the height of other battery cells 8, so that two battery cells are arranged on two sides of the top end of the battery cell 8, and false detection is avoided. The correlation sensor comprises a transmitter 351 and a receiver 352, and when the normal battery cell 8 is inserted in place, the receivers 352 of the two correlation sensors can both receive signals sent by the generator 351; if the battery cell 8 is not inserted in place, at least the high side interrupts the signal from the corresponding transmitter 351 and cannot be received by the receiver 352, thereby triggering a predetermined protection mechanism when the battery cell 8 is not inserted in place.
