Description

Technical Field

[0001] The utility model relates to the technical field of buffer transition devices, in particular to a polar coil storage and retrieval buffer needle bearing device. Background Art

[0002] During the battery trial production and production process, the rolled and slit pole pieces will be rolled into pole rolls through the barrel for use in the winding process. Generally, the pole rolls rolled into pole pieces are temporarily stored on the rack and are not directly transported to the equipment for use. When employees store or remove pole rolls, they will use a transfer cart, connect the transfer shaft of the transfer cart to the support shaft of the rack, and manually push and pull the barrel to drag the pole rolls on the rack out or into the transfer shaft of the transfer cart.

[0003] At present, deep groove ball bearings are distributed on the support shaft used in the material rack, but the transition bearing is not installed on the outer side of the support shaft (the front end of the support shaft). When taking materials, after the barrel passes the deep groove ball bearing at the front end, one end is unsupported and the pole roll will tilt downward. The employee needs to lift the pole roll slightly and put the barrel on the roller of the transfer shaft. Similarly, when storing materials, the pole roll needs to be lifted after the barrel passes the roller at the front end of the transfer shaft so that it can be put on the deep groove ball bearing of the support shaft of the material rack. If the employee is negligent, the pole piece will slide on the barrel like a gyroscope. Adjusting the position of the pole piece will easily cause damage to the pole piece, which will affect the pole piece correction in the winding process when used. There is no transition bearing buffer at the front end of the support shaft, so more effort and time are required when taking materials, and the barrel is easily scratched and worn by the support shaft. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art. To achieve the above purpose, a polar winding material storage and retrieval buffer needle bearing device is adopted to solve the problems raised in the above background technology.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Please refer to Figure 1 and Figure 2 In the embodiment of the utility model, a polar coil storage and retrieval buffer needle bearing device comprises:

[0027] Base 2;

[0028] A needle bearing 1 is disposed on the middle raised portion of the base 2; and

[0029] A U-shaped groove 3 is provided on the side of the base 2;

[0030] The base 2 supports the needle bearing 1 to buffer, transition and receive the pole coil 11 when storing and retrieving materials, and cooperates with the U-shaped groove 3 to discharge foreign matter.

[0031] In this embodiment, the needle bearing device 12 is arranged on the rack assembly.

[0032] like Figure 3 As shown, the figure is a side view of the rack assembly;

[0033] like Figure 4 As shown, the figure is a schematic diagram of the three-dimensional structure of the material rack assembly;

[0034] In this embodiment, the rack assembly includes a rack 7, a support shaft 8 disposed on the rack 7, an end cap 9 disposed at the end of the support shaft 8, a deep groove ball bearing 13 disposed on the support shaft 8, an extremely thin roll 11 disposed on the support shaft 8, and a cartridge 10 disposed on the support shaft 8.

[0035] In this embodiment, the base 2 is disposed at the end of the support shaft 8.

[0036] The device is installed on the top of the support shaft 8, between the deep groove ball bearing 13 and the end cap 9, and close to the end cap 9. The device can be fixed to the support shaft 8 using bolts 5.

[0037] In this embodiment, the base 2 has an overall I-shaped structure, and the base 2 is a hollow structure with a convex middle part.

[0038] In this embodiment, the needle roller bearing device 12 includes a needle roller bearing 1 disposed on the base 2, a retaining plate 6 disposed on one side of the base 2, and a bolt 5 for fixing the retaining plate 6.

[0039] In this embodiment, the needle roller bearing 1 is installed on the base 2 through a mounting shaft 4.

[0040] In this embodiment, the needle roller bearing device 12 is installed between the deep groove ball bearing 13 and the end cap 9.

[0041] The needle roller bearing device 12 is arranged in the rack assembly. The length of the cartridge is limited. When it is transferred to the support shaft 8, the front end lacks bearing support. When the coil 11 moves from the front end to the mid-front position where the deep groove ball bearing 13 is provided, due to the height difference between the bearing position and the non-bearing position, it is difficult for the cartridge to be smoothly pushed forward, resulting in the coil 11 being prone to slipping on the cartridge. In order to ensure that the height of the front end is the same as the height of the mid-front roller, and thus ensure that there is no obvious height difference between the front and back of the support shaft, the needle roller bearing device 12 is designed.

[0042] In the specific implementation, the base 2 is overall I-shaped, with the middle part convex and hollow for placing the needle roller bearing 1. The bottom is machined to match the curvature of the corresponding support shaft 8 and fits with the support shaft 8. It is installed between the deep groove ball bearing 13 and the end cap 9, and the base 2 is fixed to the support shaft 8 using bolts 5. There is a through hole on one side of the middle convex part, which is the hole position for the needle roller bearing 1 and the mounting shaft 4. The needle roller bearing 1 is fixed in the hollow position using the mounting shaft 4, and the retaining plate 6 is installed. The retaining plate 6 is fixed to the base 2 using bolts 5 to separate the mounting shaft 4 from the outside; a U-shaped groove 3 is opened in the area near the bottom on the other side to facilitate cleaning and discharging foreign objects. The height of the pick-up buffer needle roller bearing device 12 has no height difference from the original deep groove ball bearing 13 on the support shaft 8 of the rack 7.
