DETAILED DESCRIPTION

[0060] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0061] In order to clearly describe and understand the patent, in addition to the tooling designed in the patent, the structures of other tooling and part of the structures of the equipment are also given in the drawings.

[0062] Embodiment 1

[0063] Please refer to Figures 1-8 A retired power battery disassembly production line, comprising:

[0064] Tray 5, the retired power battery pack is placed on the tray 5;

[0065] Moving trolley 4, the moving trolley 4 comprises base plate 41, support rod 42 and rotating wheel 43; the rotating wheel 43 is rotatably installed at the bottom of the support rod 42, and the top ends of the plurality of support rods 42 are fixedly connected to the lower end face of the base plate 41;

[0066] Workstation 1, the workstation 1 comprises:

[0067] Base 11, support plate 12 and jacking device 13, the support plate 12 is installed above the base 11 through at least one jacking device 13;

[0068] Rotating plate 14, the rotating plate 14 is rotatably installed on the upper end face of the support plate 12;

[0069] Positioning component 2: After the rotating plate 14 rotates to a predetermined angle, the positioning component 2 fixes the rotating plate 14 relative to the support plate 12.

[0070] The trolley 4 is used to transport the tray 5 containing the retired power battery pack. The trolley 4 moves above the rotating plate 14, and the lifting device 13 pushes the trolley 4 upward, so that the trolley 4 separates from the support surface.

[0071] The number of support rods 42 is generally three or more, preferably four. The shape of the base plate 41 is not limited. Considering that rotation is required in actual use, it can be circular, or the corners of a square plate can be rounded. The rotating wheel 43 can be driven by a power unit or can be a caster wheel, which can be locked in a predetermined position as needed.

[0072] It should be noted that, Figure 1 , Figure 2 The diagram shows how to place the tray 5 containing the retired power battery pack on the rotating plate 14.

[0073] As a further solution, a connecting groove is provided on the lower end face of the base, and the connecting groove and the rotating plate 14 are configured in a shape that can prevent the two from rotating relative to each other.

[0074] Furthermore, the substrate 41 is made of a transparent material, making it easy to observe the relative position of the connecting groove and the rotating plate 14.

[0075] The tray 5 containing the retired power battery pack is placed on the upper surface of the base plate 41. Then, the trolley 4 is moved to directly above the rotating plate 14 of the workstation 1. The lifting device 13 is adjusted so that the rotating plate 14 lifts the base plate 41 upwards, ensuring that the rotating wheel 43 below the support rod 42 is separated from the support surface. The height of the rotating plate 14 is further adjusted so that the operator can easily disassemble the retired power battery pack. According to the operator's needs, the base plate 41 can be moved, and the base plate 41 drives the rotating plate 14 to rotate together. After rotating at a predetermined angle, the positioning component 2 fixes the rotating plate 14 again.

[0076] It should be noted that the support rod 42 needs to rotate on the outside of the base.

[0077] As a further solution, multiple limiting members 51 are provided, which are detachably installed on the upper surface of the tray 5. One side of the limiting member 51 abuts against the outer wall of the battery pack, while the bottom surface of the limiting member 51 is fixed relative to the tray 5, thereby limiting the battery pack.

[0078] Furthermore, the limiting member 51 is fixed to the upper end face of the rotating plate 14 by magnetic attraction or adhesive.

[0079] Obviously, the battery pack casing can also be magnetically attached to the upper surface of tray 5.

[0080] Further, the limiting member 51 can be strip-shaped, L-shaped, circular arc-shaped, etc.

[0081] As a further solution, with reference to Figure 1 , Figure 2 The jacking device 13 comprises a plurality of first linear drive devices, which are fixed on the base 11, and the output ends of the plurality of first linear drive devices are fixed on the bottom surface of the support plate 12.

[0082] The first linear drive device can adopt any one of a hydraulic cylinder, an air cylinder, and an electric cylinder, but in order to ensure that the plurality of first linear drive devices can move synchronously, a corresponding servo system needs to be provided.

[0083] The jacking device 13 can also be implemented in other structures, such as an X-shaped lifting frame, a screw block mechanism, etc.

[0084] As a further solution, with reference to Figure 1 , Figure 2 A foot cup is also provided, and a plurality of foot cups are uniformly distributed on the bottom surface of the base. The number of foot cups is preferably 4, and the levelness of the base can be adjusted by adjusting the threaded rods and nuts of the foot cups.

[0085] It should be noted that the shapes of the base, the support plate 12, and the rotating plate 14 are not limited.

[0086] It should also be noted that the manner in which the rotating plate 14 is rotatably connected to the support plate 12 in the present solution is to use a plain bearing, and the two ends of the plain bearing are fixed with the rotating plate 14 and the support plate 12, respectively. In order to limit the relative positions of the rotating plate 14 and the support plate 12, mounting holes can be provided on the lower end surface of the rotating plate 14 and the upper end surface of the support plate 12, respectively, and the two ends of the plain bearing are respectively clamped into the mounting holes on the upper and lower sides.

[0087] Obviously, the rotatable connection between the rotating plate 14 and the support plate 12 can also be achieved in other ways. For example, it can be achieved by a rotating shaft 32 matched with a bearing and a sleeve. The rotating shaft 32 is installed at the center of the upper end surface of the support plate 12, the rotating shaft 32 is a stepped shaft, the bearing is installed on the small shaft of the rotating shaft 32, and the lower end surface of the inner ring of the bearing abuts against the stepped surface of the rotating shaft 32. The sleeve is installed at the center of the lower end surface of the rotating plate 14, the inner cavity of the sleeve is a stepped hole, the outer sidewall of the outer ring of the bearing abuts against the large hole of the sleeve, and the upper end surface of the outer ring of the bearing abuts against the stepped surface of the inner cavity of the sleeve.

[0088] Embodiment 2

[0089] The support assembly 3 of Embodiment 1 is further described.

[0090] With reference to Figure 4At least three support assemblies 3 are arranged, and the support assemblies 3 are arranged at intervals and used for supporting the rotating plate 14. The number of the support assemblies 3 is preferably four. However, it is obvious that more support assemblies 3 can be selected.

[0091] The support assemblies 3 are arranged for supporting the rotating plate 14 and ensuring the horizontal degree of the rotating plate 14. In addition, the support assemblies 3 can share the stress in the vertical direction of the bearing for realizing the rotating connection between the rotating plate 14 and the support plate 12.

[0092] Further, the support assembly 3 comprises:

[0093] A mounting groove 31 arranged on the support plate 12 or the rotating plate 14;

[0094] A rotating shaft 32 and a support bearing 33. The two ends of the rotating shaft 32 are fixed on the inner side wall of the mounting groove 31, the inner ring of the support bearing 33 is fixed on the outer side wall of the rotating shaft 32, and the outer ring of the support bearing 33 is in abutment with the lower end surface of the rotating plate 14.

[0095] Figure 4 And Figure 5 A manufacturing scheme of the mounting groove 31 is shown. A steel plate is bent into a U shape, and the inner recess in the middle of the U-shaped steel plate is the mounting groove 31. A groove is opened on the support plate 12, and the U-shaped steel plate is inserted into the groove. In this scheme, the two end portions of the U-shaped steel plate can be horizontally folded outward, and the folded portions are fixed to the support plate 12 by bolts.

[0096] The U-shaped steel plate can also be fixed to the support plate 12 by welding.

[0097] It should be noted that if the support assembly 3 is arranged on the rotating plate 14, the thickness of the rotating plate 14 needs to be increased because the upper end surface of the rotating plate 14 needs to be flat (a battery pack needs to be placed), or the end portion of the U-shaped steel plate is fixed to the rotating plate 14, and the outer side wall of the outer circle of the support bearing 33 can be in close contact with the upper end surface of the support plate 12.

[0098] It should be further noted that the rotating shaft 32 and the support bearing 33 can be replaced by a ball. The shape of the mounting groove 31 is set as an arc shape that matches the ball. However, the end of the ball exposed from the mounting groove 31 is in point contact with the support plate 12 or the rotating plate 14. The contact point needs to bear a large pressure.

The center lines of the multiple positioning holes 21 coincide with the axis of rotation of the rotating plate 14, so that the positioning member 23 at one end of the pipe column 22 can be inserted into the corresponding positioning hole 21. When the number of pipe columns 22 is multiple, the multiple pipe columns 22 are arranged along the same circumference, and the center lines of the multiple pipe columns 22 coincide with the center lines of the multiple positioning holes 21.

Alternatively, the pipe column 22 and the positioning hole 21 can be respectively arranged on the outer side wall of the rotating plate 14 and the support plate 12. Preferably, the pipe column 22 and the positioning hole 21 are arranged on the lower end surface of the rotating plate 14 and the upper end surface of the support plate 12.
