Claims (10)

1. base; A base support member that is mounted on an external transfer device and transferred, with the base coupled to the upper end; A support cone formed in a shape that protrudes upward from the upper surface of the base and is inserted into a can for a secondary battery; and A magnet positioned adjacent to the bottom of the support cone, which presses the secondary battery can against the base; is included. On the above base, A support cone seating groove is formed by being recessed on the upper surface in a shape corresponding to the lower surface of the support cone so that the lower part of the support cone can be seated and received, and a magnet receiving groove is formed penetrating from the lower surface toward the support cone seating groove and receiving the magnet. The above support cone is fixed to the base while seated in the support cone seating groove, and The magnet receiving groove is connected to the support cone seating groove so that a portion of the magnet is exposed to the support cone seating groove when the magnet is received. In the above support cone, In a state where it is seated in the support cone seating groove, a magnet placement groove is formed extending upward from the bottom surface to accommodate the magnet exposed to the support cone seating groove, and The above magnet is, A first magnet positioned biased to one side with respect to the central axis of the support cone; and A carrier for a secondary battery can, comprising: a second magnet positioned to be biased toward the other side with respect to the central axis of the support cone.

Description

A carrier of the can for secondary battery The present invention relates to a carrier for a can of a secondary battery. Rechargeable batteries convert chemical energy into electrical energy to supply power externally, and when discharged, they can receive an external power supply to convert electrical energy back into chemical energy for storage. Rechargeable batteries are produced in various forms, such as cylindrical, prismatic, and pouch types, and among them, cylindrical batteries, the generally used form, remain widely used to this day. Cylindrical batteries are manufactured by inserting a jelly roll into a cylindrical can. To prevent safety accidents caused by external defects of secondary batteries, the can forming the exterior of the cylindrical battery undergoes an external inspection before the jelly roll is inserted. This external inspection applies not only to the can of cylindrical batteries but also to the cans and caps forming the exterior of prismatic batteries, and the pouches forming the exterior of pouch-type batteries. In this case, the components constituting the battery's exterior as described above are often manufactured by incorporating paramagnetic materials such as aluminum. To improve the efficiency of visual inspection of cans, caps, and pouches for secondary batteries (hereinafter referred to as "cans, etc."), a large quantity of cans, etc. is transported using automated transport equipment such as conventional conveyor systems and robot systems, and the cans, etc. are visually inspected through inspection devices located along the transport path. At this time, in order to prevent the cans, etc. from tipping over or tilting during rapid movement via the transport equipment and to maintain the posture required for inspection, the cans, etc. could be loaded and mounted on an inspection carrier. To ensure that the cans, etc. do not detach from the carrier during rapid transport and to stably maintain the posture required for inspection, the carrier transporting the cans, etc. requires a fixing force that maintains the cans, etc. in the correct position. FIG. 1 is a drawing showing a state in which one can is mounted on a carrier of a secondary battery can according to one embodiment of the present invention. Figure 2 is a drawing showing the can and carrier shown in Figure 1 separated, and some components of the carrier disassembled. FIG. 3 is a drawing illustrating a support cone according to one embodiment of the present invention. FIG. 4 is a bottom view of a support cone according to one embodiment of the present invention. FIG. 5 is a drawing illustrating a base according to one embodiment of the present invention. FIG. 6 is a bottom view of a base according to one embodiment of the present invention. FIG. 7 is a drawing showing a can for a secondary battery positioned on a support cone according to one embodiment of the present invention. Figure 8 is a drawing showing a support cone being inserted into a can for a secondary battery as illustrated in Figure 7. FIG. 9 is a drawing showing the secondary battery can shown in FIG. 8 completely inserted into the support cone. The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Furthermore, the embodiments described herein will be explained with reference to cross-sectional views and/or schematic drawings, which are exemplary illustrations of the present invention. Accordingly, the form of the exemplary drawings may be modified due to manufacturing techniques and/or tolerances, etc. Additionally, in each drawing of the present invention, each component may be depicted slightly enlarged or reduced for convenience of explanation. Throughout the specification, the same reference numerals refer to the same components. The present invention is described below using the application to a cylindrical can as an example. However, a person skilled in the art may apply the principles of the present invention to other batteries, such as prismatic or pouch-type batteries, and the scope of the present invention should be interpreted to extend to such cases. Furthermore, the directions mentioned below, such as up, down, front, back, left, and right, are merely described after establishing one direction for a clear understanding of the present invention, and do not limit the invention. Therefore, the directions of up, down, front, back, left, and right may change during the actual application of the present invention, and t
