[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Please refer to Figures 1 to 3 A battery flip mechanism comprises a frame 1, a synchronous belt 2 and a flip part 3, wherein: the synchronous belt 2 is arranged on the frame 1, and is used to transport a battery cell shell 4 along a first direction X; the flip part 3 is arranged on the frame 1, and the flip part 3 comprises a driving member 34 and a flip shaft 32 rotatably mounted on the frame 1, the axial direction of the flip shaft 32 is not parallel to the first direction X, a receiving member is arranged on the flip shaft 32, and a receiving cavity 30 for receiving the battery cell shell 4 is opened on the receiving member, and the driving member 34 is used to drive the flip shaft 32 to rotate so that the receiving member switches between a loading position and a unloading position; when the receiving member is in the loading position, the opening end of the receiving cavity 30 faces the upstream side of the first direction X; when the receiving member is in the unloading position, the opening end of the receiving cavity 30 faces the downstream side of the first direction X; when the receiving member is in the loading position and the unloading position, the synchronous belt 2 can extend into the receiving cavity 30.

[0027] like Figure 1 As shown, in this embodiment, the extension direction of the synchronous belt 2 is the first direction X. When in use, the accommodating part is first rotated to the loading position through the flip shaft 32. At this time, the synchronous belt 2 transports the battery cell shell 4 from the open end of the accommodating chamber 30 to the accommodating chamber 30. Then, the driving member 34 drives the flip shaft 32 to rotate so that the accommodating part switches from the loading position to the unloading position. During the process, the open end of the accommodating chamber 30 gradually rises in the longitudinal direction, and the battery cell shell 4 in the accommodating chamber 30 is separated from the synchronous belt 2. The open end of the accommodating chamber 30 rises to the highest point and then gradually decreases. When the opening end of the accommodating chamber 30 faces the downstream side of the first direction X, the battery cell shell 4 in the accommodating chamber 30 contacts the synchronous belt 2, and the synchronous belt 2 transports the battery cell shell 4 out of the accommodating chamber 30 from the opening end of the accommodating chamber 30, so that the battery cell shell 4 can be turned over during the transportation process, which is conducive to improving production efficiency; the battery cell shell 4 is limited by the non-power during the turning process of the accommodating chamber 30, and there is no risk of pinching or deforming the battery cell shell 4 compared with the traditional mechanical fixing method, which can greatly improve the product yield of the battery cell shell 4. Optionally, the driving member 34 is a motor.

[0028] like Figure 1 and Figure 2 As shown, X1 is the upstream side of the first direction X, and X2 is the downstream side of the first direction X.

[0029] like Figure 2As shown, the accommodating member includes two flip plates 31 arranged in a mirror image, the flip plates 31 are fixedly mounted on the flip shaft 32, the accommodating chamber 30 is in the area between the two flip plates 31, and the synchronous belt 2 is between the two flip plates 31; a longitudinal positioning structure 333 and at least two lateral positioning structures 332 are provided on the flip plates 31, when the accommodating member is in the upper material position and the lower material position, the longitudinal positioning structure 333 is arranged close to the flip shaft 32, in the longitudinal direction, the battery cell housing 4 is between the at least two lateral positioning structures 332, and at least part of the synchronous belt 2 is higher than the lateral positioning structure 332 close to the synchronous belt 2; in the axial direction of the flip shaft 32, the distance between the two corresponding lateral positioning structures 332 on the two flip plates 31 is smaller than the size of the battery cell housing 4.

[0030] It should be noted that, in the axial direction of the turning shaft 32 , the width of the synchronous belt 2 is smaller than the size of the battery cell housing 4 .

[0031] Preferably, the axial direction of the flip axis 32 is perpendicular to the first direction X.

[0033] When in use, the synchronous belt 2 transports the battery cell housing 4 to the accommodating chamber 30, that is, between the two lateral positioning structures 332. Figure 2 As shown, when the accommodating part rotates from the upper material position to the lower material position, the battery cell shell 4 first contacts the lateral positioning structure 332 at the lower side at the upper material position, and then the accommodating part rotates counterclockwise under the action of the flip shaft 32. During the process, due to the gradual inclination of the lateral positioning structure 332 at the lower side, the battery cell shell 4 slides down and abuts against the longitudinal positioning structure 333 on the side close to the flip shaft 32. After the opening end of the accommodating chamber 30 rotates past the highest point, the battery cell shell 4 slides relative to the longitudinal positioning structure 333 until it abuts against the lateral positioning structure 332 on the upper side when the accommodating part is in the upper material position, that is, in the longitudinal direction, the positions of the two lateral positioning structures 332 at the upper material position and the lower material position are interchanged, and then the accommodating part reaches the lower material position, the battery cell shell 4 abuts against the synchronous belt 2, and under the action of the synchronous belt 2, moves out of the accommodating chamber 30 from the outlet end of the accommodating chamber 30 along the first direction X to complete the flipping of the battery cell shell 4.

[0034] Optionally, the longitudinal positioning structure 333 is the first surface, and the lateral positioning structure 332 is the second surface. Preferably, the first surface and the second surface are both planes. In other embodiments, the first surface and the second surface may also be curved surfaces.

[0035] like Figure 2 and Figure 3 As shown, a jig plate 33 is provided on the flip plate 31, and a receiving groove 331 is provided on the jig plate 33. The longitudinal positioning structure 333 and the lateral positioning structure 332 are both groove walls of the receiving groove 331.

In this way, the jig plate 33 can be easily replaced to adapt to the use of different types of battery cell housings 4.

Accordingly, the battery flip mechanism includes at least two synchronous belts 2 corresponding to the at least two accommodating members.

[0038] In this embodiment, a chamfered edge 334 is provided on the groove wall of the accommodating groove 331; the chamfered edge 334 is arranged opposite to the longitudinal positioning structure 333; when the accommodating member is in the loading position, the chamfered edge 334 is arranged close to the upstream side of the first direction X.

Preferably, there are two guide plates 5, and the two guide plates 5 are symmetrically disposed about the synchronous belt 2. When in use, the guide plate 5 is disposed on the upstream side of the first direction X, specifically the upstream side of the flipping portion 3, and the posture of the battery cell housing 4 is corrected before the battery cell housing 4 enters the accommodating cavity 30 so that the battery cell housing 4 is aligned with the opening end of the accommodating cavity 30.

[0041] Preferably, the guide plate 5 is slidably connected to the frame 1. Specifically, a slide rail is provided on the frame 1, and the slide rail is extended along the axial direction of the flip shaft 32, and a slider adapted to the slide rail is provided on the guide plate 5. The frame 1 is also provided with a telescopic member 6 for driving the guide plate 5 to slide relative to the synchronous belt 2.
