[0037] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0038] In the present disclosure, unless otherwise stated, directional words such as "first direction" may refer to Figure 1 The directional words used, such as "upper and lower", refer to the upper and lower parts of the conveying mechanism of the present disclosure defined in normal use. Figure 1 As shown; the terms such as "first, second", etc. used are only used to distinguish one element from another element and do not have sequential and important meanings.

[0039] Reference Figures 1 to 5 As shown, the present disclosure provides a conveying mechanism, which includes a support frame 1, a conveying track 2 and a conveying member 3 for clamping an external component 100, the conveying track 2 is arranged on the support frame 1, the conveying member 3 can move along the conveying track 2, the conveying track 2 includes a plurality of conveying sections 20 that are sequentially connected to each other and laid flat, the plurality of conveying sections 20 include at least one flipping conveying section 21, and the flipping conveying section 21 is constructed so that: the conveying member 3 can move along the extension direction of the flipping conveying section 21 and flip around it.

[0040] In the above technical solution, the support frame 1 supports the conveying track 2 to ensure the stability of the conveying track 2. The conveying track 2 includes a plurality of conveying sections 20 that are interconnected and laid flat. Since the conveying sections 20 are laid flat, and the conveying sections 20 include at least one flipping conveying section 21 that can realize the flipping transportation of the conveying member 3, the flipping conveying section 21 is also laid flat, which meets the flipping requirements of the external component 100 clamped on the conveying member 3 while avoiding the conveying track 2 from being too high, reducing the space occupied by the conveying track 2, facilitating the later maintenance of the conveying track 2, and avoiding safety hazards caused by high-altitude maintenance.

[0041] It should be noted that the above-mentioned conveying mechanism can be applied to any appropriate conveying line scenario, especially the application scenario where the external component 100 needs to be turned over before the station operation can be performed. For example, the above-mentioned conveying mechanism can be applied to the welding conveying line of the battery cell or battery, the double-sided air blowing and dust removal conveying line of the battery, the double-sided tape conveying line of the battery, the double-sided film coating conveying line of the battery, and the double-sided welding conveying line of the battery cell FTT (Friction Stir Welding), etc. The present disclosure does not limit the specific application scenarios of the above-mentioned conveying mechanism.

[0042] In one embodiment, the flipping conveying section 21 may include a cylindrical track (not shown) extending along the first direction A, and the outer surface of the cylindrical track is recessed with a spiral groove extending and winding along the first direction A. The conveying member 3 is movably engaged in the spiral groove. The design of the spiral groove can, on the one hand, realize the requirement of the conveying member 3 moving and flipping along the first direction A. On the other hand, the conveying member 3 is engaged in the spiral groove, which can also prevent the conveying member 3 from detaching from the flipping conveying section 21 during the flipping process.

[0043] For example, the conveying member 3 includes a conveying member body (not shown) and a roller (not shown), the conveying member body is used to clamp the external component 100, the roller is rotatably arranged on the conveying member body, the cross-section structure of the spiral groove is a T-slot shape, the roller is embedded in the spiral groove and forms rolling friction with the inner wall of the spiral groove.

[0044] In this embodiment, firstly, the conveying member body can clamp the external component 100 in any appropriate manner. For example, the conveying member body can be provided with clamping members such as clamping claws to achieve stable clamping of the external component 100. Secondly, the roller can be rotatably arranged on the conveying member body and form rolling friction with the inner wall of the spiral groove. Then, the conveying member 3 can utilize the small friction coefficient between the roller and the inner wall of the spiral groove. There is no need to separately provide a power member to drive the conveying member 3 to move. The conveying member 3 can move in the spiral groove by utilizing its own movement inertia. In addition, the roller is embedded in the spiral groove with a cross-sectional structure in the shape of a T-slot, which can ensure that the roller will not detach from the spiral groove during the rolling process, thereby realizing the flipping requirement of the external component 100 on the conveying member 3.

[0045] Or, in another embodiment, referring to Figure 1 As shown, the flipping conveying section 21 may further include a spiral track 211 extending along the first direction A, and the conveying member 3 may be movably clamped on the spiral track 211 to ensure that the conveying member 3 is flipped while preventing the conveying member 3 from detaching from the spiral track 211.

[0046] For example, the roller is clamped on the spiral track 211 and forms rolling friction with the surface of the spiral track 211. First, the roller forms rolling friction with the surface of the spiral track 211, and the conveying member 3 can utilize the characteristic of a small rolling friction coefficient. There is no need to separately set up a power member to drive the conveying member 3 to move. The conveying member 3 can use its own movement inertia to achieve movement on the spiral track 211. Secondly, the present disclosure does not limit the specific manner in which the roller is clamped to the spiral track 211. For example, the roller can be constructed as a roller coaster roller structure, which can include a roller bracket (not shown), a first roller (not shown), a second roller (not shown), a third roller (not shown) and a fourth roller (not shown). The first roller, the second roller, the third roller and the fourth roller can be rotatably arranged on the roller bracket, the first roller and the second roller are arranged opposite to each other and clamped to the spiral track 211, the third roller and the fourth roller are arranged opposite to each other and clamped to the spiral track 211, that is, the clamping of the spiral track 211 is achieved by using two groups of oppositely arranged rollers to avoid detachment from the spiral track 211.

[0047] In addition, refer to Figure 1As shown, the multiple conveying sections 20 also include at least one straight conveying section 22, and the straight conveying section 22 can make the conveying member 3 move in a straight direction to meet the demand of the external component 100 on the conveying member 3 to move in a straight direction. The straight conveying section 22 can be set as one or more, and the present disclosure does not limit the number of arrangements of the straight conveying sections 22. The straight conveying section 22 can be constructed as any appropriate conveying structure, and the present disclosure does not limit this. Alternatively, the multiple conveying sections 20 of the present disclosure may also include a curved conveying section (not shown) to meet the demand for curved conveying of the external component 100, and the present disclosure does not limit this.

[0048] For example, the linear conveying section 22 includes a magnetic suspension moving part and a magnetic suspension conveying track 221 extending in a linear direction, the magnetic suspension moving part is movably arranged on the magnetic suspension conveying track 221 and can carry the conveying member 3, and the flip conveying section 21 is connected to the magnetic suspension conveying track 221. That is, the linear conveying section 22 can be constructed as a magnetic suspension conveying structure, the magnetic suspension moving part is movably arranged on the magnetic suspension conveying track 221, and the conveying member 3 is arranged on the magnetic suspension moving part to realize the linear movement of the external component 100 on the magnetic suspension conveying track 221, with stable driving and high movement accuracy.

[0049] In other embodiments, referring to Figures 1 to 5 As shown, the support frame 1 includes at least one support beam 11, and the support beam 11 is arranged in a one-to-one correspondence with the straight conveying section 22, and the support beam 11 is supported and connected to the magnetic suspension conveying track 221, so as to achieve stable support for the conveying track 2. For example, the support beam 11 may include two support vertical beams 112 and a support horizontal beam 111 connected between the two support vertical beams 112, and the support horizontal beam 111 effectively supports the magnetic suspension conveying track 221. The support beam 11 has a simple structure and stable driving, but the present disclosure does not limit the specific structure of the support beam 11.
