The first driving member 211 can drive the distance measuring member 23 to translate along the Y direction through the first sliding frame 22 after being started. Since the single-row battery cells 200 extend in the Y direction, measuring only the distance of the distance measuring member 23 to one point of the single-row battery cells 200 may result in poor accuracy. In this embodiment, the distance measuring member 23 translates along the Y direction to measure the distances between the distance measuring member 23 and the plurality of points of the single-row battery cells 200, and the average value is taken as the distance between the current distance measuring member 23 and the single-row battery cells 200, thereby improving the accuracy and reliability of the measured value.

The pressing mechanism 4 is used for pressing the single-row battery cells 200 on the bottom wall of the clamping piece 121 so that the bottom surfaces of the single-row battery cells 200 are level. Since the battery cell assembly is finally mounted in the lower case of the battery, the bottom surface of the electric wire needs to be fully contacted with the inner bottom wall of the lower case, so that the bottom surface of the battery cell 201 is required to be flush, and the stability of the battery cell assembly when mounted in the lower case of the battery is ensured. The cross section of the clamping piece 121 is approximately L-shaped, grooves matched with the peripheral surfaces of the electric cores 201 are formed in the vertical plates of the L-shaped pieces, the bottom surfaces of the electric cores 201 are arranged on the transverse plates of the L-shaped pieces, and when the electric cores 201 are assembled, the bottom surfaces of all the electric cores 201 are required to be in contact with the transverse plates of the L-shaped pieces, so that the bottom surfaces of all the electric cores 201 are guaranteed to be flush.
