Description

Technical Field

[0001] [Cross - reference to Related Applications] This application claims the benefit of priority based on Korean Patent Application No. 10 - 2023 - 0055500, filed on April 27, 2023, and Korean Patent Application No. 10 - 2024 - 0050947, filed on April 16, 2024, and all the contents disclosed in the documents of the Korean patent applications are incorporated herein by reference.

[0002] The present invention relates to a battery transfer tray, and more specifically, to a battery transfer tray capable of buffering the impact caused by a collision during transfer via a roller conveyor.

Background Art

[0003] Currently commonly used batteries include nickel - cadmium batteries, nickel - metal hydride batteries, nickel - zinc batteries, lithium batteries, etc. Among these, lithium batteries have attracted attention for their advantages of having almost no memory effect compared to nickel - series batteries, being free in charging and discharging, having a very low self - discharge rate, and a high energy density.

[0004] During the manufacturing process or when transporting finished products, batteries are stored in a single tray and then transferred to subsequent processes or delivery locations. At this time, it is important for the tray to be able to stably support the stored multiple batteries so that they are not damaged during transfer.

[0005] In particular, when trays containing batteries are transported via a roller conveyor, the distance between the rollers is large, so the leading edge of a random tray may sometimes enter the empty space between the rollers, potentially causing a collision between the tray's leading edge and the roller. When a collision occurs between the tray and the roller, the impact is directly transmitted to the battery contained in the tray, resulting in damage such as bending, wrinkling, or tearing, leading to a poor appearance. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] The present invention aims to solve the aforementioned problems and provides a battery transport tray that can reduce damage to batteries caused by collisions by cushioning the impact of collisions that occur between the tray and the rollers when the tray containing the batteries is transported via a roller conveyor. [Means for solving the problem]

[0007] According to a first embodiment of the present invention, the present invention provides a battery transfer tray comprising: an outer frame provided for housing a plurality of batteries; a support portion protruding from the lower surface of the outer frame and forming a step with respect to the lower surface of the outer frame; and an inclined unit comprising a first inclined portion and a second inclined portion, provided to cushion the impact caused by collision with rollers when a roller conveyor moves, wherein the first inclined portion is an inclined surface formed between the lower surface of the outer frame and the end of the support portion, and the second inclined portion is an inclined surface formed on both sides of the first inclined portion and is inclined in a direction away from the first inclined portion.

[0008] Furthermore, the outer frame may be provided with an inner frame to which the plurality of batteries are aligned.

[0009] Furthermore, the first inclined portion may be formed at an angle of 10° to 30° with respect to the lower surface of the outer frame.

[0010] Furthermore, the second inclined portion may be formed to be longer in the direction toward both sides of the first inclined portion than the width of the first inclined portion.

[0011] Furthermore, the second inclined portion may be formed in a flat shape.

[0012] Furthermore, multiple inclined units may be formed along the periphery of the support portion.

[0013] Furthermore, the outer frame may include a mounting portion provided to which the inner frame is attached; side wall portions formed perpendicular to the mounting portion on both sides of the mounting portion; and a boundary portion at the upper end of the side wall portion that forms a periphery corresponding to the periphery of the mounting portion along the periphery of the mounting portion.

[0014] Furthermore, the upper surface of the boundary portion may be formed flat.

[0015] Furthermore, stacking grooves may be formed on the upper surface of the boundary portion at positions corresponding to the positions of the inclined unit, so that multiple battery transfer trays can be stacked on top of each other.

[0016] Furthermore, the stacking groove may be provided so that the inclined unit of the battery transfer tray located in the upper layer when multiple battery transfer trays are stacked can be inserted.

[0017] Furthermore, the mounting portion may have multiple heat dissipation holes that communicate with the outside so as to cool the battery.

[0018] Furthermore, the mounting portion may have mounting holes that penetrate it so that the inner frame can be attached to the mounting portion via a fastening unit.

[0019] Further, the mounting holes may be formed in parallel along a corner of the mounting portion so as to guide the position of the inner frame.

[0020] Further, graduations may be formed in parallel along a corner of the mounting portion so as to measure the position of the inner frame.

Advantages of the Invention

[0021] The present invention can provide a battery transfer tray that can prevent the battery from being damaged by a collision by buffering the impact caused by the collision even when a tray containing a battery is transferred via a roller conveyor and a collision occurs between the tray and the roller.

[0022] Also, a stable stacking structure can be formed between a plurality of battery transfer trays.

Modes for Carrying Out the Invention

[0024] The present invention will be described more specifically below with reference to the drawings. However, the following drawings are for the purpose of facilitating understanding of the present invention and represent only one embodiment of the invention; the scope of the present invention is not limited to the scope shown in the drawings. Furthermore, the same reference numerals in the following drawings refer to the same components, and some components may be exaggerated, reduced, or omitted in order to facilitate understanding of the invention.

[0025] Furthermore, the terms and words used in this specification and the claims shall not be interpreted in a manner limited to their ordinary and lexicographical meanings, but rather in a manner consistent with the technical idea of ​​the present invention, in accordance with the principle that inventors themselves may define the concepts of terms as appropriate in order to best describe their invention.

[0026] First Example The battery transfer tray 10 can accommodate multiple batteries in its internal space, and the battery transfer tray 10 containing the batteries can be transported via a user or via a conveyor.

[0027] The battery transfer tray 10 can align and store multiple batteries in its internal space that have been manufactured and formed into finished products, allowing the stored batteries to be transferred all at once, and enabling the stored batteries to be repeatedly charged and discharged during the activation process that activates the batteries.

[0028] Referring to Figure 1, in a first embodiment of the present invention, the battery transfer tray 10 of the present invention may include an outer frame 100, a support portion 200, and a tilting unit 300.

[0029] The outer frame 100 is positioned at the upper end of the support portion 200 and can form the overall external shape of the battery transfer tray 10.

[0030] The outer frame 100 can create open space within the internal space surrounded by the outer frame 100.

[0031] The outer frame 100 can have numerous rib structures formed on its outer surface to prevent deformation due to temperature changes, physical impacts, etc. The rib structure can improve the mechanical strength of the outer frame 100, reduce its weight and other factors to improve ease of transport and storage, and reduce manufacturing costs.

[0032] The outer frame 100 may be made of an electrically insulating material so as not to electrically affect the charging and discharging processes of the battery housed in the internal space. It may also include, but is not limited to, polymers, rubber materials, etc.

[0033] The outer frame 100 may be formed in a hexahedral shape overall, and openings may be formed on one or more sides. The inner frame 400 and the battery may flow into the internal space of the outer frame 100 through the openings in the outer frame 100.

[0034] The outer frame 100 may include a mounting portion 110, a side wall portion 120, and a boundary portion 130.

[0035] The mounting portion 110 forms the bottom surface of the outer frame 100, and the inner frame 400, which flows into the internal space of the outer frame 100, may be attached by a fastening unit (not shown).

[0036] The mounting portion 110 may be formed in the shape of a rectangular plate, and the mounting portion 110 may have a number of heat dissipation holes 111 of various sizes.

[0037] The heat dissipation holes 111 allow liquids and gases that can be discharged from the battery during the activation process into the internal space of the outer frame 100 to be discharged to the outside, and when the battery generates heat due to repeated charging and discharging, the heat can be dissipated and the battery can be cooled.

[0038] The heat dissipation holes 111 may be arranged symmetrically from a center line that crosses the center of the mounting portion 110, and may include various types of heat dissipation holes 111 formed in various sizes and patterns. Since heat dissipation holes 111 of the same size are arranged in a specific area of ​​the mounting portion 110, the user can predict the position in which the inner frame 400 is attached to the mounting portion 110 based on the size of the heat dissipation holes 111 arranged around the inner frame 400 attached to the mounting portion 110. Since multiple inner frames 400 are arranged symmetrically, it is possible to easily confirm whether multiple inner frames 400 are arranged symmetrically by the size and arrangement of the heat dissipation holes 111 around the inner frame 400.

[0039] The mounting hole 112 may be a through hole formed in the mounting portion 110 so that the inner frame 400 can be attached to the mounting portion 110.

[0040] The mounting hole 112 may be formed in the shape of a slot hole, parallel to one corner of the mounting portion 110, so that the inner frame 400 can move along the mounting portion 110 and be guided to a position where it can be fully mounted.

[0041] The mounting hole 112 may be formed with a width sufficient to allow the insertion of bolts, screws, etc. of the fastening unit, and a length that extends along one corner of the mounting portion 110.

[0042] Multiple mounting holes 112 may be formed symmetrically with respect to a center line such that multiple inner frames 400 are arranged symmetrically with respect to a center line that crosses the center of the mounting portion 110.

[0043] Furthermore, multiple mounting holes 112 may be formed at predetermined intervals along the longitudinal direction of the center line that crosses the center of the mounting portion 110, so that the inner frame 400 can be firmly attached to the mounting portion 110.

[0044] A scale portion 113 may be formed on the mounting portion 110, extending from one end to the other along the longitudinal direction of the mounting hole 112.

[0045] Referring to Figure 4, the scale section 113 may display the position of the center line as "0" based on the center line that crosses the center of the mounting section 110, and markings may be displayed at predetermined intervals in both directions perpendicular to the center line. The scale section 113 may be formed so that the numbers indicating the position of the markings gradually increase in both directions based on "0".

[0046] The scale section 113 provides numerical information to ensure that the multiple inner frames 400 attached to the mounting section 110 are installed in the correct positions. The user can determine the precise position of the inner frame 400 by measuring the lower end position of the inner frame 400 using the scale on the scale section 113.

[0047] The scale section 113 is formed such that the numbers indicating the scale position gradually increase in both directions, with "0" as the reference point, so that multiple inner frames 400 can be mounted in precisely symmetrical positions on the mounting section 110.

[0048] Multiple scale sections 113 may be formed on the mounting section 110. Multiple scale sections 113 may be arranged so as to be spaced apart by a predetermined distance. Since the longitudinal directions of the multiple inner frames 400 are arranged perpendicular to the longitudinal direction of the mounting holes 112, if there is only one scale section 113, it is difficult to tell if the arrangement direction of the inner frames 400 is shifted using only one scale section 113. Therefore, multiple scale sections 113 can be arranged to prevent the arrangement direction of the inner frames 400 from shifting.

[0049] A detachment prevention projection 114 may be formed on the periphery of the mounting portion 110, which is higher than the inner upper surface.

[0050] The anti-detachment projection 114 can prevent a portion of the battery stored in the battery transfer tray 10 from detaching from the area of ​​the battery transfer tray 10 if the inner frame 400 to which it is attached becomes detached.

[0051] The detachment prevention projection 114 may be formed along the rectangular periphery of the mounting portion 110.

[0052] Numerous rib structures are formed on the outer surface of the detachment prevention projection 114, which improves the mechanical strength of the detachment prevention projection 114 and supports the rectangular shape of the mounting portion 110 so that it is not deformed by heat, temperature, physical impact, etc.

[0053] The side wall portion 120 may be a wall formed on both sides of the mounting portion 110, perpendicular to the upper surface of the mounting portion 110 and extending upward. The side wall portion 120 may be formed on one side and the other end of the mounting portion 110, and more specifically, it may be formed perpendicular to the upper surface of the anti-detachment projection 114 formed on one side and the other end of the mounting portion 110.

[0054] The side wall portion 120 forms a vertical wall of a predetermined height, thereby confirming the size of the internal space of the battery transfer tray 10 in the height direction, and enabling the battery to be supported and housed in the inner frame 400.

[0055] Numerous rib structures are formed on the outer surface of the side wall portion 120, which improves the mechanical strength of the side wall portion 120 and supports the side wall portion 120 so that its shape is not deformed by heat, temperature, physical impact, etc.

[0056] The boundary portion 130 is positioned at the upper end of the side wall portion 120, and at least a part of it is connected to the upper end of the side wall portion 120. It may be provided to form a periphery corresponding to the periphery of the mounting portion 110 along the periphery of the mounting portion 110. Since the boundary portion 130 is formed along the periphery of the mounting portion 110, it may be formed in the shape of a rectangular ring, and the inner surface of the boundary portion 130 may form an opening for the battery transfer tray 10.

[0057] Furthermore, in the area of ​​the mounting portion 110 where the side wall portion 120 is not formed, it may be separated from the boundary portion 130 by a distance corresponding to the height of the side wall portion 120, and an opening may be formed in the space formed by the separation between the mounting portion 110 and the boundary portion 130. The battery transfer tray 10 may have an opening formed via the inner surface of the boundary portion 130, and an opening may be formed in the separated space between the boundary portion 130 and the mounting portion 110.

[0058] The boundary portion 130 may be positioned at the upper end of the side wall portion 120 and form the internal space of the battery transfer tray 10. The battery transfer tray 10 may be formed in an overall hexahedral shape via the mounting portion 110, the side wall portion 120, and the boundary portion 130.

[0059] The area of ​​the boundary portion 130 that directly faces the mounting portion 110 is separated from the side wall portion 120 by a predetermined distance, and this area can function as a handle so that the user can directly grasp and carry it.

[0060] Numerous rib structures are formed on the outer surface of the boundary portion 130, which can improve the mechanical strength of the boundary portion 130 and support the shape of the side wall portion 120 so that it is not deformed by heat, temperature, physical impact, etc. In particular, when a user grasps the boundary portion 130 to transport the battery transfer tray 10, the boundary portion 130 may include numerous rib structures on its outer surface so that the area of ​​the boundary portion 130 grasped by the user can support the weight of the battery transfer tray 10 and the batteries stored therein. The rib structures formed on the boundary portion 130 may include not only horizontal and vertical grid-like rib structures formed on the side wall portion 120 and the mounting portion 110, but also "X" shaped rib structures. Therefore, the mechanical strength of the boundary portion 130 may be stronger than that of the side wall portion 120 and the mounting portion 110.

[0061] The upper surface of the boundary portion 130 may be formed in a flat shape, and multiple battery transfer trays 10 may be stacked. In a stack of multiple battery transfer trays 10, the upper surface of the boundary portion 130 of the battery transfer tray 10 located in the lower layer may be in contact with the lower surface of the battery transfer tray 10 located in the upper layer.

[0062] Referring to Figure 3, stacking grooves 131 may be formed on the upper surface of the boundary portion 130 at positions corresponding to the positions of the inclined unit 300, so that multiple battery transfer trays 10 can be stacked on top of each other.

[0063] Since the inclined unit 300 is formed to protrude from the lower surface of the battery transfer tray 10, when the battery transfer trays 10 are stacked, the protruding inclined unit 300 may create an unstable stacked structure. Therefore, a stacking groove 131 is formed on the upper surface of the boundary portion 130 so that the inclined unit 300 of the battery transfer tray 10 placed on the upper layer is inserted into the stacking groove 131, thereby creating a stable stacked structure.

[0064] Furthermore, since the inclined unit 300 of the battery transfer tray 10 placed in the upper layer is inserted into the stacking groove 131 of the battery transfer tray 10 placed in the lower layer, the position of the battery transfer tray 10 placed in the upper layer can be stably fixed, and when the stacked battery transfer trays 10 are transported via a roller conveyor, the stacked structure can be stably maintained even when shaken by collisions or the like.

[0065] The lamination grooves 131 may be formed on the upper surface of the boundary portion 130 so as to correspond to the positions of the inclined units 300, and the number of grooves may correspond to the number of inclined units 300.

[0066] The shape of the laminated groove 131 is not limited to this, but may include, for example, a shape corresponding to the shape of the inclined unit 300, a shape formed to a predetermined height corresponding to the shape of the widest cross-section of the inclined unit 300, or a shape with a volume greater than the volume of the inclined unit 300 so that the inclined unit 300 is fully inserted.

[0067] A locking groove 132 may be formed on the upper surface of the boundary portion 130 at a certain depth along the inner periphery of the upper surface of the boundary portion 130. When multiple battery transfer trays 10 are stacked, the locking groove 132 is inserted into the support portion 200 of the battery transfer tray 10 placed on the upper layer, so that the stacked structure is stably maintained.

[0068] Since the locking groove 132 is formed along the inner periphery of the upper surface of the boundary portion 130, the periphery of the support portion 200 of the battery transfer tray 10, which is positioned on the upper layer, may be inserted into the locking groove 132 inside the periphery of the locking groove 132. When the support portion 200 is inserted into the locking groove 132, the inner surface of the locking groove 132 and the outer surface of the support portion 200 may be in contact with each other.

[0069] Multiple laminated grooves 131 may be arranged at predetermined intervals along the longitudinal direction of the locking groove 132. The depth of the laminated grooves 131 may be the same as the depth of the locking groove 132.

[0070] The support portion 200 may support the outer frame 100 at its lower part. The support portion 200 may have a shape that protrudes from the lower surface of the outer frame 100. The support portion 200 may form a step with respect to the lower surface of the outer frame 100. Specifically, the support portion 200 may be formed on the lower surface of the outer frame 100 and form a step in the direction toward the inside of the outer frame 100.

[0071] More specifically, the support portion 200 may be formed to protrude perpendicularly from the lower surface of the mounting portion 110, and a stepped step may be formed inward relative to the periphery of the mounting portion 110. The step formed by the support portion 200 relative to the mounting portion 110 ensures that when the battery transfer tray 10 is transported via a roller conveyor, even if the lower end of the tray collides with a roller, it will pass over the colliding roller via the stepped step.

[0072] The support portion 200 may have corresponding holes 210 formed in a shape corresponding to the position of the heat dissipation holes 111 and mounting holes 112 formed in the mounting portion 110, or in a shape larger than the size of the heat dissipation holes 111 and mounting holes 112. The corresponding holes 210 can guide the liquid and gas discharged during the activation process of the battery that has flowed into the internal space of the outer frame 100 to be discharged to the outside of the battery transfer tray 10 through the heat dissipation holes 111, and can dissipate heat and cool the battery when it is repeatedly charged and discharged and generates heat.

[0073] Furthermore, the corresponding hole 210, formed at a position corresponding to the mounting hole 112, is larger than the mounting hole 112, so that fastening units such as bolt heads and nuts can be inserted, and the fastening units can pass through the mounting hole 112 to fasten the mounting portion 110 and the inner frame 400.

[0074] Referring to Figures 5 and 6, the inclined unit 300 is an inclined surface formed in the step between the lower surface of the outer frame 100 and the outer surface of the support part 200. When the battery transfer tray 10 is transferred to the roller conveyor, if a collision occurs between the roller and the lower end of the battery transfer tray 10, the inclined unit 300 and the roller come into contact, dispersing and cushioning the impact of the collision, allowing the battery transfer tray 10 to move over the roller it collided with via the inclined surface of the inclined unit 300.

[0075] Multiple inclined units 300 may be formed for each step between the outer surface of the support portion 200 and the lower surface of the outer frame 100. Alternatively, multiple inclined units 300 may be formed along the periphery of the support portion 200. This allows collisions with the rollers to be buffered in all directions, even if the direction of transport changes while the battery transport tray 10 is being transported to the roller conveyor.

[0076] The inclined unit 300 may include a first inclined section 310 and a second inclined section 320. This allows the inclined unit 300 to be configured to absorb impacts from collisions with rollers in various directions during the movement of the roller conveyor.

[0077] The first inclined portion 310 may be an inclined surface formed between the lower surface of the outer frame 100 and the end of the support portion 200. Here, the end of the support portion 200 may mean the vicinity of the corner of the lower end of the outer surface of the support portion 200.

[0078] The first inclined portion 310 can most effectively cushion the impact when the outer surface of the support portion 200 of the battery transfer tray 10 collides head-on with the roller. However, when the outer surface of the support portion 200 and the roller collide at an angle, forming a predetermined angle, the impact-cushioning effect may be reduced. Therefore, by including a curved shape on its outer surface, the first inclined portion 310 can effectively cushion the impact even when the outer surface of the support portion 200 and the roller collide at an angle, forming a predetermined angle.

[0079] The curved shape included in the first inclined portion 310 may be convex with respect to the inclined surface, and may be formed to be symmetrical in both directions with respect to a central axis formed along the longitudinal direction of the first inclined portion 310.

[0080] The curved shape included in the first inclined portion 310 may be formed so as to be smoothly connected to each other at the boundary between the second inclined portions 320 formed on both sides of the first inclined portion 310 and the first inclined portion 310.

[0081] The inclination angle of the first inclined portion 310 may be formed at an angle of 10° to 30° with respect to the lower surface of the outer frame 100.

[0082] The second inclined portion 320 may be an inclined surface formed on both sides of the first inclined portion 310, with an inclination in a direction away from the first inclined portion 310. That is, the second inclined portion 320 may be formed in a diagonal or perpendicular direction to the inclination direction of the first inclined portion 310. The second inclined portion 320 may be formed to be longer than the width of the first inclined portion 310 in the direction on both sides of the first inclined portion 310. The second inclined portion may be formed in a flat shape.

[0083] The second inclined section 320 effectively disperses and cushions the impact when the outer surface of the support section 200 of the battery transfer tray 10 and the rollers of the roller conveyor collide at a predetermined angle, allowing the battery transfer tray 10 to move over the colliding rollers via the inclined surface of the second inclined section 320.

[0084] The first inclined portion 310 and the second inclined portion 320 of the inclined unit 300 effectively disperse the impact not only when the outer surface of the support portion 200 and the rollers collide head-on as the battery transfer tray 10 moves along the roller conveyor, but also when they collide at an angle forming a predetermined angle, thereby minimizing the impact received by the batteries stored inside the battery transfer tray 10.

[0085] Second Example A second embodiment of the present invention, described with reference to Figure 2, may include a battery transfer tray 10 assembly and a plurality of inner frames 400 attached to the battery transfer tray 10. The battery transfer tray 10 may include an outer frame 100, a support portion 200, and a tilting unit 300, the details of which can be replaced by the description of the first embodiment described above. The inner frames 400 may be arranged to align a plurality of batteries upright, and the inner frames 400 may be attached to the mounting portion 110 of the battery transfer tray 10 via fastening units.

[0086] Multiple inner frames 400 may be provided, and a number of partition plates 410 may be arranged at predetermined intervals along the longitudinal direction of the inner frame 400. Multiple batteries can be placed between partition plates 410 and adjacent partition plates 410, and can be upright and stably supported by the partition plates 410. The positions of the multiple inner frames 400 can be adjusted so that they are located symmetrically on the mounting portion 110. The inner frames 400 can be attached to the mounting portion 110 by fastening units such as bolts and nuts to fastening portions 420.

[0087] Although the present technology has been described above through embodiments, the present technology is not limited thereto. The embodiments may be modified or altered without deviating from the spirit and scope of the present technology, and a person ordinary in the art will understand that such modifications and alterations also belong to the present technology.
