[0027] Please see Figure 1-7 A cylindrical battery OCV testing device includes a device base 1, a top plate 2 fixedly provided at the top of the device base 1, a battery feeding assembly above the top plate 2, and a battery movement detection assembly below the top plate 2.

[0028] The battery movement detection assembly includes a battery guide seat 4 fixedly connected to the top plate 2, a detection seat 3 slidably connected to the bottom end of the battery guide seat 4, the detection seat 3 being connected to a displacement driving mechanism, and a detection mechanism being provided above the detection seats 3 on both sides of the battery guide seat 4.

[0029] The detection seat 3 has multiple detection slots 21 extending through it, and a bottom cover 20 is rotatably connected to the detection seat 3 at the bottom of each detection slot 21.

[0030] The detection mechanism includes a first lifting rod 16 fixedly installed at the bottom of the top plate 2. The telescopic end of the first lifting rod 16 is fixedly connected to the lifting seat 15. Multiple detection heads are fixedly connected to the bottom of the lifting seat 15. Multiple second lifting rods 17 are fixedly installed at the bottom of the top plate 2 on one side of the first lifting rod 16. Multiple third lifting rods 18 are fixedly connected to the bottom of the top plate 2 on the side of the second lifting rod 17 away from the first lifting rod 16.

[0031] The battery feeding assembly includes a feeding cover 5 disposed above the top plate 2. An installation rod 10 is fixedly connected between the feeding cover 5 and the top plate 2. The feeding cover 5 is inclined. Multiple feeding guide rails 11 are fixedly connected to the bottom of the feeding cover 5. Each feeding guide rail 11 is fixedly connected to an arc-shaped guide cover 6 between itself and the battery guide seat 4. A vertical guide groove 13 communicating with the arc-shaped guide cover 6 is opened through the battery guide seat 4.

[0032] A vibration motor 12 is fixedly connected to the bottom end of the feeding hood 5.

[0033] The displacement driving mechanism includes guide side seats 7 fixedly disposed on both sides of the detection seat 3.
