Flipping device and use method thereof, and flipping method for battery module

A flipping method for a battery module, comprising:

• placing the battery module on a first supporting member, wherein the first supporting member and the battery module form a to-be-flipped member;
• clamping the to-be-flipped member;
• lifting the to-be-flipped member using a lifting mechanism;
• flipping the lifted to-be-flipped member using a flipping mechanism rotatably connected to the lifting mechanism and comprising a flipping drive mechanism and a driven mechanism arranged at an interval, the flipping drive mechanism and the driven mechanism being respectively rotatably connected to the lifting mechanism, and a rotation axis of the flipping drive mechanism being colinear with a rotation axis of the driven mechanism;
• placing a second supporting member below the lifted to-be-flipped member;
• lowering the battery module relative to the second supporting member;
• and
• maintaining the clamping to the first supporting member and releasing the clamping to the battery module, and making the second supporting member to carry the battery module.

A flipping device, comprising:

• a device frame, wherein at least part of the device frame is configured to be arranged beside a conveying line, the conveying line is configured to convey a to-be-flipped member, the to-be-flipped member comprises a first supporting member and a battery module placed on the first supporting member, and the conveying line is further configured to convey a second supporting member to below the to-be-flipped member after the to-be-flipped member is lifted;
• a blocking mechanism, configured to block the to-be-flipped member located on the conveying line or to block the second supporting member located on the conveying line, and the blocking mechanism being capable of being lifted and lowered relative to the conveying line;
• a lifting mechanism, wherein the lifting mechanism is capable of being lifted and lowered relative to the device frame;
• a flipping mechanism, wherein the flipping mechanism is rotatably connected to the lifting mechanism;
• a first clamping mechanism, wherein the first clamping mechanism is arranged on the flipping mechanism and the first clamping mechanism is configured to clamp the first supporting member;
• and
• a second clamping mechanism, wherein the second clamping mechanism is arranged on the flipping mechanism, the second clamping mechanism is configured to clamp the battery module and release the clamping to the battery module independently of the first clamping mechanism, the second clamping mechanism comprises a third clamping assembly and a fourth clamping assembly, the third clamping assembly and the fourth clamping assembly are arranged in a second direction, and the second direction is parallel to a flipping axis of the flipping mechanism.
