Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, specifically a type of support cup. Background Technology

[0002] During battery production, the battery steel casing needs to be loaded into a tray and then transferred between multiple processes, such as casing insertion, necking, welding, electrolyte injection, capping, and sealing. Because the tray containing the battery steel casing needs to be flipped or rotated during transfer according to process requirements, and there is also a certain degree of vibration during this process, the battery steel casing is prone to shaking within the tray. This friction and collision can cause scratches and other defects on the outer surface of the battery steel casing. Utility Model Content

[0003] Therefore, it is necessary to provide a cup that can avoid defects such as scratches on the outer surface of the battery steel casing to address the above problems.

[0004] A cup holder, comprising:

[0005] The cup holder body has a receiving cavity, a first opening and a second opening communicating with the receiving cavity, and the first opening and the second opening are respectively located at the two ends of the axial direction of the cup holder body;

[0006] Multiple spring clips are spaced apart circumferentially on the inner wall of the receiving cavity; and

[0007] A bottom support is disposed at one end of the cup body having the second opening, and at least partially protrudes from the inner wall of the receiving cavity.

[0008] In some embodiments, the base support includes an annular portion and a plurality of base supports. The annular portion is connected to one end of the cup body having the second opening and extends circumferentially along the cup body. The plurality of base supports protrude from the inner side of the annular portion and are spaced apart along the extending direction of the annular portion.

[0009] In some embodiments, the annular portion is coaxially arranged with the cup body.

[0010] In some embodiments, the inner wall of the receiving cavity is recessed to form an annular groove, the annular groove being located at one end of the cup body having the second opening and extending circumferentially along the cup body, the annular portion being engaged in the annular groove.

[0011] In some embodiments, the inner wall of the receiving cavity is provided with a plurality of strip-shaped protrusions, and each of the strip-shaped protrusions is arranged at intervals along the circumference of the cup body;

[0012] Each of the spring pieces is divided into multiple groups of spring pieces, each group of spring pieces includes two spring pieces, and the multiple groups of spring pieces correspond one-to-one with the multiple strip-shaped protrusions. The two spring pieces of each group of spring pieces are connected to the corresponding strip-shaped protrusions.

[0013] In some embodiments, each of the spring pieces has a connecting end connected to the corresponding strip boss and a free end extending circumferentially along the cup body relative to the connecting end; the free ends of two spring pieces connected to the same strip boss extend in a direction to avoid diverging.

[0014] In some embodiments, the cup holder further includes a plurality of limiting strips respectively disposed on each of the strip protrusions, each of the limiting strips being located between two springs of the corresponding spring group.

[0015] In some embodiments, each of the strip-shaped protrusions, each of the spring pieces, and each of the limiting strips extends along the axial direction of the cup body.

[0016] In some embodiments, the cup holder body, each of the strip-shaped protrusions, each of the spring pieces, and each of the limiting strips are integrally formed.

[0017] In some embodiments, the cup holder further includes a reinforcing sleeve fitted over the outside of the cup holder body and a magnetic suction layer fitted between the cup holder body and the reinforcing sleeve.

[0018] In actual use, the aforementioned cup holder inserts the battery casing into the receiving cavity through the first opening of the cup holder body until the battery casing is supported on the base support. At this point, the battery casing compresses the various spring clips, causing the spring clips to elastically deform and exert a reaction force on the battery casing, thereby fixing the battery casing within the receiving cavity. In other words, the battery casing is fixed within the receiving cavity by the combined action of the base support and the various spring clips, thus preventing the battery casing from wobbling relative to the cup holder body within the receiving cavity, and consequently avoiding defects such as scratches on the outer surface of the battery casing.

[0029] Please see Figures 1 to 4 This application provides a cup holder, including a cup holder body 10, a plurality of spring clips 20, and a bottom support 60. The cup holder body 10 has a receiving cavity 11, a first opening 13, and a second opening 14. The first opening 13 and the second opening 14 are located at opposite axial ends of the cup holder body 10 and are both connected to the receiving cavity 11. That is, the cup holder body 10 is a cylindrical structure with openings at both ends. The plurality of spring clips 20 are spaced apart circumferentially on the inner wall of the receiving cavity 11 to secure the battery casing inserted into the receiving cavity 11 and prevent the battery casing from shaking within the receiving cavity 11. The bottom support 60 is located at the end of the cup holder body 10 with the second opening 14 and at least partially protrudes from the inner wall of the receiving cavity 11, thereby supporting the battery casing inserted into the receiving cavity 11 and preventing the battery casing from falling out of the second opening 14.

[0030] In actual use, the battery casing is inserted into the receiving cavity 11 through the first opening 13 of the cup body 10 until it rests on the base support 60. At this point, the battery casing compresses the various spring tabs 20, causing them to elastically deform and exert a reaction force on the casing, thus fixing it within the receiving cavity 11. In other words, the battery casing is fixed within the receiving cavity 11 by the combined action of the base support 60 and the spring tabs 20, preventing it from wobbling relative to the cup body 10 within the cavity and thus avoiding scratches or other defects on its outer surface.

[0031] It should be noted that in this embodiment, the cup is used to hold the battery steel casing. Of course, in other embodiments, the cup can also be used to hold other workpieces, and this is not limited here. For ease of understanding, this article uses the use of the cup to hold the battery steel casing as an example for explanation.

[0032] It should also be noted that, in order to load the battery steel casing, the shape of the cup body 10 matches the shape of the battery steel casing. For example, if the battery steel casing is cylindrical, then the cup body 10 is cylindrical, so that the receiving cavity 11 of the cup body 10 is cylindrical, ensuring that the battery steel casing can be inserted into the receiving cavity 11 through the first opening 13.

[0033] In the embodiments of this application, the base support 60 includes an annular portion 61 and a plurality of base support portions 62. The annular portion 61 is connected to one end of the cup body 10 having a second opening 14 and extends in a ring shape along the circumference of the cup body 10. The plurality of base support portions 62 protrude from the inner side of the annular portion 61 and are spaced apart along the longitudinal extension direction of the annular portion 61. Thus, when loading the battery steel shell, the battery steel shell is inserted into the receiving cavity 11 through the first opening 13 until the bottom of the battery steel shell contacts each base support portion 62, so that each base support portion 62 together supports the battery steel shell, making the battery steel shell inserted into the receiving cavity 11 more stable.

[0034] Preferably, the annular portion 61 is coaxially arranged with the cup body 10, so that the battery steel shell inserted into the receiving cavity 11 is coaxial with the annular portion 61 and the cup body 10, further ensuring that the battery steel shell can be more stably supported on each base portion 62.

[0035] Preferably, each base support 62 is evenly arranged along the circumference of the annular portion 61, further enhancing the stability of each base support 62 in supporting the battery steel shell.

[0036] It should be noted that, in Figure 2 In the illustrated embodiment, the number of base portions 62 is five. Of course, the number of base portions 62 is not limited to five; in other embodiments, it may be four, six, or seven, etc., depending on the size of the cup, and is not limited here.

[0037] In a specific embodiment, the inner wall of the receiving cavity 11 is recessed to form an annular groove 16 (see...). Figure 4 The annular groove 16 is located at the end of the cup holder body 10 with the second opening 14 and extends in a ring shape along the circumference of the cup holder body 10. The annular portion 61 of the bottom support 60 is engaged in the annular groove 16, thereby realizing the assembly of the cup holder body 10 and the bottom support 60. In this way, by fixing the annular portion 61 of the bottom support 60 with the annular groove 16, the assembly of the bottom support 60 and the cup holder body 10 is realized, with a simple structure and a stable connection.

[0038] In the embodiments of this application, the inner wall of the receiving cavity 11 of the cup body 10 is provided with a plurality of strip-shaped protrusions 30, and each strip-shaped protrusion 30 is arranged at intervals along the circumference of the cup body 10. Each spring piece 20 is divided into multiple groups of spring pieces 201, and each group of spring pieces 201 includes two spring pieces 20. Each group of spring pieces 201 corresponds one-to-one with each strip-shaped protrusion 30, and the two spring pieces 20 of each group of spring pieces 201 are connected to the corresponding strip-shaped protrusion 30. Thus, compared with the scheme of directly connecting the spring pieces 20 to the inner wall of the receiving cavity 11, in this embodiment, the spring pieces 20 are set by using the strip-shaped protrusions 30 on the inner wall of the receiving cavity 11, ensuring that the spring pieces 20 have sufficient deformation space, minimizing the length of the spring pieces 20, which is beneficial to improving the positioning effect of the battery steel shell and extending the service life of the spring pieces 20.

[0039] Furthermore, each spring piece 20 has a connecting end 21 connected to the corresponding strip-shaped protrusion 30 and a free end 23 extending circumferentially along the cup body 10 relative to the connecting end 21. The free ends 23 of the two spring pieces 20 connected to the same strip-shaped protrusion 30 extend in opposite directions, so that there is a certain gap between the free end 23 of each spring piece 20 and the inner wall of the receiving cavity 11. When squeezed by the battery steel shell, each spring piece 20 can produce elastic deformation with its free end 23 approaching the inner wall of the receiving cavity 11, and there is no interference between the individual spring pieces 20.

[0040] Furthermore, the cup holder also includes multiple limiting strips 40 respectively disposed on each of the strip-shaped protrusions 30. On the same strip-shaped protrusion 30, the limiting strip 40 is located between two spring pieces 20. In this way, when the battery steel shell is inserted into the receiving cavity 11 through the first opening 13, the battery steel shell is supported by each of the bottom supports 62, that is, the axial direction of the battery steel shell is limited; at the same time, the radial direction of the battery steel shell is limited by each of the spring pieces 20 and each limiting strip 40. The setting of the limiting strip 40 greatly improves the limiting effect of the battery steel shell, thereby avoiding defects such as surface scratches caused by the battery steel shell shaking in the receiving cavity 11.

[0041] Specifically, each strip protrusion 30, each spring piece 20 and each limiting strip 40 extends along the axial direction of the cup body 10, which makes the limiting effect on the battery steel shell more effective and avoids the battery steel shell from being unstable due to uneven force on the upper and lower ends.

[0042] Specifically, the cup holder body 10, each strip-shaped protrusion 30, each spring piece 20, and each limiting strip 40 are integrally molded. Furthermore, the cup holder body 10, each strip-shaped protrusion 30, each spring piece 20, and each limiting strip 40 can be integrally molded using injection molding, resulting in a more stable structure, simplified assembly process, and reduced production costs. Optionally, the cup holder body 10, each strip-shaped protrusion 30, each spring piece 20, and each limiting strip 40 can be made of elastic plastics such as polypropylene.

[0043] Understandably, when the battery casing is not inserted into the receiving cavity 11 of the cup, the inscribed circle formed by the free ends 23 of each spring piece 20 is the first inscribed surface. The diameter of this first inscribed circle is smaller than the diameter of the receiving cavity 11 and slightly smaller than the diameter of the battery casing. The inscribed circle formed by each base portion 62 is the second inscribed circle. The diameter of this second inscribed circle is smaller than the diameter of the first inscribed circle and smaller than the diameter of the battery casing. The inscribed circle formed by each limiting strip 40 is the third inscribed surface. The diameter of this third inscribed circle is larger than the diameter of the first inscribed circle, smaller than the diameter of the receiving cavity 11, and slightly larger than the diameter of the battery casing. Thus, when the battery casing is inserted into the receiving cavity 11 through the first opening 13, the battery casing is supported on each base portion 62, and each spring piece 20 is elastically deformed by the compression of the battery casing, thereby limiting the battery casing under the elastic force provided by each spring piece 20.

[0044] In embodiments of this application, the cup holder further includes a reinforcing cylinder 50 and a magnetic layer 70. The reinforcing cylinder 50 is sleeved on the outside of the cup holder body 10, and the magnetic layer 70 is sleeved between the cup holder body 10 and the reinforcing cylinder 50. The reinforcing cylinder 50 may be made of a material with greater strength than the cup holder body 10 (e.g., polyethylene) to reinforce the cup holder body 10 and prevent it from being damaged by large deformation when subjected to pressure from the battery steel shell or other external forces. The magnetic layer 70 includes a ferromagnetic material and is used to cooperate with a magnet for positioning. For example, a magnet is provided on the conveyor turntable so that the cup holder can be fixed on the conveyor turntable by the magnetic attraction between the magnetic layer 70 and the magnet, and rotate with the conveyor turntable.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
