According to the scheme, the utilization rate of the detection area projected by the ray detection module 4 is improved, and the utilization rate of the ray detection module 4 is improved.
In this embodiment, the first bearing position and the second bearing position are staggered by a certain angle in the initial state, so that the electrical core angular position on the first bearing bracket and the electrical core angular position on the second bearing bracket can sequentially and alternately fall into the detection area projected by the ray detection module 4, thereby improving the accuracy of the detection result.

The first driving mechanism 3 drives the first rotating disc 2 to rotate and drives at least one first rotating disc 2 to rotate reversely; the second driving mechanism 7 drives the second rotating disc 6 to rotate and drives at least one second rotating disc 6 to rotate reversely. Although the angular position detection efficiency of the battery core is improved, because the mounting main body is provided with a plurality of rotating discs for rotating, the centrifugal force of the first rotating discs 2 can be always in a superposed state, and the superposition of the centrifugal force of the first rotating discs 2 is easy to cause the first mounting main body 1 to vibrate; similarly, the centrifugal forces of the second rotating discs 6 may be superposed all the time, and the superposition of the centrifugal forces of the second rotating discs 6 is very likely to cause the second mounting body 5 to vibrate. In this embodiment, the first driving mechanism 3 drives part of the first rotating discs 2 to rotate in opposite directions, so that centrifugal forces which may occur when the first rotating discs 2 rotate are not always in a superposed state, thereby reducing the possibility that the first mounting main body 1 is stressed intensively in a certain direction, and further reducing the possibility that the first mounting main body 1 vibrates; correspondingly, the second driving mechanism 7 drives part of the second turntables 6 to rotate reversely, so that centrifugal force possibly generated when each second turntable 6 rotates cannot be always in a superposed state, the possibility that the second mounting main body 5 is stressed in a certain direction in a concentrated mode is reduced, and the possibility that the second mounting main body 5 vibrates is further reduced.

For example, the first driving mechanism 3 further includes a first driving wheel 34 connected to an output shaft of the first motor 35, and the first driving wheel 34 drives a plurality of first synchronizing wheels 32 to rotate. The second driving mechanism 7 further includes a second driving wheel 74 connected to an output shaft of the second motor 75, and the second driving wheel 74 drives the second synchronizing wheels 72 to rotate.
