Technology Field

[0001] The present invention relates to a battery transfer tray, and more specifically, to a battery transfer tray capable of cushioning impact caused by collision when transferred by a roller conveyor. Background Technology

[0002] Currently commercialized batteries include nickel-cadmium, nickel-hydrogen, nickel-zinc, and lithium batteries. Among these, lithium batteries are gaining attention for their advantages, such as the ability to charge and discharge freely due to almost no memory effect compared to nickel-based batteries, a very low self-discharge rate, and high energy density.

[0003] During the manufacturing process or when transporting finished products, multiple batteries are placed in a single tray and transported to subsequent processes or delivery destinations. In this process, it is important that the tray stably support the stored batteries to prevent damage during transport.

[0004] In particular, when trays containing batteries are transported via a roller conveyor, the rollers are spaced apart. Consequently, random tray fronts may enter the empty spaces between the rollers, potentially causing collisions between the tray fronts and the rollers. When such collisions occur, the impact is directly transmitted to the batteries, resulting in damage such as folding, wrinkling, or tearing, which leads to a defect in their appearance. The problem to be solved

[0005] The present invention aims to solve the above-mentioned problem by providing a battery transport tray that can reduce damage to batteries caused by collisions by cushioning the impact of collisions even when a collision occurs between a tray and a roller while the tray containing batteries is being transported via a roller conveyor. means of solving the problem

[0006] According to a first embodiment of the present invention, the present invention provides a battery transport tray comprising: an outer frame provided to accommodate a plurality of batteries; a support member 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 provided to cushion an impact caused by a collision with a roller during movement of a roller conveyor, wherein the first inclined portion is an inclined surface formed between the lower surface of the outer frame and the end of the support member, and the second inclined portion is an inclined surface formed on both sides of the first inclined portion and inclined in a direction away from the first inclined portion.

[0007] In addition, the outer frame may be provided with an inner frame that aligns the plurality of batteries.

[0008] In addition, the first inclined portion may be formed at an angle of 10° to 30° with respect to the lower surface of the outer frame.

[0009] In addition, the second inclined portion may be formed to be longer in both directions of the first inclined portion than the width of the first inclined portion.

[0010] In addition, the second inclined portion may be formed in a flat shape.

[0011] In addition, the above-mentioned inclined units may be formed in multiple numbers along the edge of the support member.

[0012] Additionally, the outer frame may include a mounting portion provided for mounting the inner frame; side wall portions formed perpendicularly 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 border corresponding to the border of the mounting portion along the border of the mounting portion.

[0013] In addition, the upper surface of the above boundary portion can be formed flat.

[0014] In addition, a stacking groove may be formed on the upper surface of the boundary portion at a position corresponding to the position of the inclined unit so that a plurality of the battery transfer trays can be stacked.

[0015] In addition, the stacking groove may be provided so that the inclined unit of the battery transfer tray located on the upper layer is inserted when a plurality of the battery transfer trays are stacked.

[0016] In addition, the mounting portion may have a plurality of heat dissipation holes communicating with the outside to cool the battery.

[0017] In addition, a mounting hole penetrating the mounting portion may be formed in the mounting portion so that the inner frame can be mounted to the mounting portion through a fastening unit.

[0018] In addition, the mounting hole may be formed parallel to one corner of the mounting portion to guide the position of the inner frame.

[0019] In addition, a scale may be formed parallel to one corner of the mounting portion so as to measure the position of the inner frame. Effects of the invention

[0020] The present invention can provide a battery transport tray that prevents damage to batteries caused by collisions by cushioning the impact caused by collisions even if a collision occurs between the tray and the roller when the tray containing batteries is transported via a roller conveyor.

[0021] In addition, a stable stacked structure can be formed between multiple battery transfer trays. Brief explanation of the drawing

[0026] First embodiment

[0027] The battery transfer tray (10) can store multiple batteries in its internal space, and the battery transfer tray (10) containing the batteries can be transported by a user or via a conveyor.

[0028] The battery transfer tray (10) can store multiple batteries in an internal space in an arranged manner, and allows the stored batteries to be transferred at once, and allows the stored batteries to be repeatedly charged and discharged during the activation process of activating the batteries.

[0029] Referring to FIG. 1, in the first embodiment of the present invention, the battery transfer tray (10) of the present invention may include an outer frame (100), a support member (200), and an inclined unit (300).

[0030] The outer frame (100) is positioned on the top of the support member (200) and can form the overall external shape of the battery transfer tray (10).

[0031] The outer frame (100) can form an empty space in the inner space surrounded by the outer frame (100).

[0032] The outer frame (100) may have a plurality of rib structures formed on its outer surface to prevent deformation caused by temperature changes, physical impacts, etc. Through the rib structures, the outer frame (100) can improve the mechanical strength of the outer frame (100), reduce weight, improve convenience for transportation and storage, and reduce manufacturing costs.

[0033] The outer frame (100) may be formed of an electrically insulating material so as not to electrically affect the charging and discharging processes of the batteries stored in the internal space. It may include, for example, polymer or rubber materials, although it is not limited thereto.

[0034] The outer frame (100) may be formed in a cuboid shape overall, and an opening may be formed on one or more sides. The inner frame (400) and batteries may be introduced into the internal space of the outer frame (100) through the opening of the outer frame (100).

[0035] The outer frame (100) may include a mounting portion (110), a side wall portion (120), and a boundary portion (130).

[0036] The mounting portion (110) forms the bottom surface of the outer frame (100), and the inner frame (400) introduced into the inner space of the outer frame (100) can be mounted through a fastening unit (not shown).

[0037] The mounting portion (110) may be formed in the shape of a rectangular plate, and a plurality of heat dissipation holes (111) of various sizes may be formed in the mounting portion (110).

[0038] The heat dissipation hole (111) allows liquid and gas that can be discharged during the activation process from the batteries introduced into the internal space of the outer frame (100) to be discharged to the outside, and can cool the batteries by dissipating heat when the batteries are repeatedly charged and discharged and generate heat.

[0039] The heat dissipation holes (111) can be arranged symmetrically from a centerline crossing the center of the mounting portion (110) and may include various types of heat dissipation holes (111) formed in various sizes and shapes. Since heat dissipation holes (111) of the same size are arranged in a specific area of ​​the mounting portion (110), the user can determine the position where the inner frame (400) is mounted on the mounting portion (110) by looking at the size of the heat dissipation holes (111) arranged around the inner frame (400) mounted on the mounting portion (110). Since the inner frame (400) is arranged symmetrically in multiple numbers, it is easy to check whether multiple inner frames (400) are arranged symmetrically by looking at the size and arrangement of the heat dissipation holes (111) around the inner frame (400).

[0040] The mounting hole (112) may be a through hole formed in the mounting portion (110) so that the inner frame (400) can be mounted to the mounting portion (110).

[0041] The mounting hole (112) may be formed in the shape of a slot hole formed parallel to one corner of the mounting portion (110) so that the inner frame (400) can move along the mounting portion (110) and guide the position where it is fully mounted.

[0042] The mounting hole (112) can be formed with a width sufficient to allow the bolt, screw, etc. of the fastening unit to be inserted, and a length that extends along one corner of the mounting part (110).

[0043] The mounting holes (112) can also be formed symmetrically with respect to a center line so that a plurality of inner frames (400) can be symmetrically arranged with respect to a center line crossing the center of the mounting portion (110).

[0044] Additionally, mounting holes (112) may be formed at predetermined intervals along the length direction of a center line crossing the center of the mounting part (110) so that the inner frame (400) can be strongly mounted to the mounting part (110).

[0045] In the mounting portion (110), a scale portion (113) may be formed along the length direction of the mounting hole (112) from one end to the other end of the mounting portion (110).

[0046] Referring to FIG. 4, the scale portion (113) indicates the position of the center line as '0' based on the center line crossing the center of the mounting portion (110), and scales may be indicated at predetermined intervals in both directions perpendicular to the center line. The scale portion (113) may be formed so that the numbers indicating the position of the scales in both directions based on '0' gradually increase.

[0047] The scale portion (113) allows for numerical determination of the position of multiple inner frames (400) mounted on the mounting portion (110). The user can determine the exact position of the inner frame (400) by measuring the lower position of the inner frame (400) using the scale of the scale portion (113).

[0048] The scale portion (113) is formed such that the numbers indicating the scale position in both directions based on '0' gradually increase, thereby allowing a plurality of inner frames (400) to be mounted in an accurately symmetrical position on the mounting portion (110).

[0049] Multiple scale sections (113) may be formed on the mounting section (110). Multiple scale sections (113) may be spaced apart at a predetermined distance. Since the length direction of multiple inner frames (400) is arranged perpendicular to the length direction of the mounting hole (112), if there were only one scale section (113), it would be difficult to detect that the arrangement of the inner frame (400) is misaligned by using only one scale section (113), so multiple scale sections (113) can be arranged to prevent the arrangement direction of the inner frame (400) from being misaligned.

[0050] A detachment prevention ridge (114) formed at the edge of the mounting part (110) may be formed with a height higher than that of the inner upper surface.

[0051] The anti-detachment projection (114) can prevent some of the batteries stored in the battery transfer tray (10) from detaching from the area of ​​the tray (10) when the mounting of the inner frame (400) is released and detached.

[0052] The anti-detachment projection (114) can be formed along the rectangular border of the mounting portion (110).

[0053] A plurality of rib structures are formed on the outer surface of the anti-detachment jaw (114) to improve the mechanical strength of the anti-detachment jaw (114) and to support the rectangular shape of the mounting part (110) so that it is not deformed by heat, temperature, physical impact, etc.

[0054] The side wall portion (120) may be a wall formed on both sides of the mounting portion (110) in an upward direction perpendicular to the upper surface of the mounting portion (110). The side wall portion (120) may be formed at one end and the other end of the mounting portion (110), and more specifically, may be formed in an upward direction perpendicular to the upper surface of the anti-detachment projection (114) formed at one end and the other end of the mounting portion (110).

[0055] The side wall portion (120) can expand the size of the internal space of the battery transfer tray (10) in the height direction by forming a vertical wall of a predetermined height, and can allow batteries to be supported and stored in the inner frame (400).

[0056] A plurality of rib structures are formed on the outer surface of the side wall (120) to improve the mechanical strength of the side wall (120) and to support the shape of the side wall (120) so that it is not deformed by heat, temperature, physical impact, etc.

[0057] The boundary portion (130) is positioned at the upper end of the side wall portion (120) such that at least a portion is connected to the upper end of the side wall portion (120), and can be arranged to form a boundary corresponding to the boundary of the mounting portion (110) along the edge of the mounting portion (110). Since the boundary portion (130) is formed along the edge of the mounting portion (110), it can be formed as a rectangular ring structure, and the inner surface of the boundary portion (130) can form an opening of the battery transfer tray (10).

[0058] Additionally, the area where the side wall (120) is not formed in the mounting portion (110) may be spaced apart 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 space between the mounting portion (110) and the boundary portion (130). The battery transfer tray (10) may have an opening formed through the inner surface of the boundary portion (130), and an opening may be formed in the spaced-apart space between the boundary portion (130) and the mounting portion (110).

[0059] The boundary portion (130) can be positioned at the top of the side wall portion (120) to form the internal space of the battery transfer tray (10). Through the mounting portion (110), the side wall portion (120), and the boundary portion (130), the battery transfer tray (10) can be formed in an overall cuboid shape.

[0060] The area facing directly to the mounting portion (110) at the boundary portion (130) is spaced apart from the side wall portion (120) by a predetermined distance, and the area can function as a handle so that the user can directly grasp and carry it.

[0061] A plurality of rib structures are formed on the outer surface of the boundary portion (130) to improve the mechanical strength of the boundary portion (130) and to support the shape of the side wall portion (120) so that it does not deform due to 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 a plurality of 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-shaped 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).

[0062] The upper surface of the boundary portion (130) can be formed in a flat shape, and a plurality of battery transfer trays (10) can be stacked. Among the stacked plurality of battery transfer trays (10), the upper surface of the boundary portion (130) of the battery transfer tray (10) placed on the lower layer can come into contact with the lower surface of the battery transfer tray (10) placed on the upper layer.

[0063] Referring to FIG. 3, a stacking groove (131) may be formed on the upper surface of the boundary portion (130) at a position corresponding to the position of the inclined unit (300) so that a plurality of battery transfer trays (10) can be stacked.

[0064] Since the inclined unit (300) is formed to protrude from the lower surface of the battery transfer tray (10), an unstable stacking structure may be formed due to the protruding inclined unit (300) when the battery transfer tray (10) is stacked. Accordingly, 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 forming a stable stacking structure.

[0065] In addition, since the inclined unit (300) of the battery transfer tray (10) placed on the upper layer is inserted into the stacking groove (131) of the battery transfer tray (10) placed on the lower layer, the position of the battery transfer tray (10) placed on the upper layer can be stably fixed, and the stacking structure can be stably maintained even when the stacked battery transfer trays (10) are transported via a roller conveyor and shaken by collisions, etc.

[0066] The stacking grooves (131) can be formed on the upper surface of the boundary portion (130) to correspond to the position of the inclined unit (300), and can be formed in a number corresponding to the number of inclined units (300).

[0067] The shape of the stacking groove (131) is not limited thereto, but may be formed to include, for example, a shape corresponding to the shape of the inclined unit (300), a shape formed with a predetermined height corresponding to the shape of the widest cross-section of the inclined unit (300), or a shape having a larger volume than the volume of the inclined unit (300) so that the inclined unit (300) can be fully inserted.

[0068] A catch groove (132) may be formed at a constant depth along the inner edge of the upper surface of the boundary portion (130) on the upper surface of the boundary portion (130). When a plurality of battery transfer trays (10) are stacked, the catch groove (132) is inserted into the support portion (200) of the tray (10) placed on the upper layer so that the stacked structure can be stably maintained.

[0069] Since the catch groove (132) is formed along the inner edge of the upper surface of the boundary portion (130), the edge of the support portion (200) of the tray (10) placed on the upper surface of the catch groove (132) can be inserted into the inner edge of the catch groove (132). When the support portion (200) is inserted into the catch groove (132), the inner surface of the catch groove (132) and the outer surface of the support portion (200) can come into contact with each other.

[0070] A plurality of stacked grooves (131) may be arranged at predetermined intervals along the longitudinal direction of the catch groove (132). The depth of the stacked groove (131) may be formed to be equal to the depth of the catch groove (132).

[0071] The support member (200) can support the outer frame (100) from the lower part of the outer frame (100). The support member (200) may have a shape that protrudes from the lower surface of the outer frame (100). The support member (200) may form a step with respect to the lower surface of the outer frame (100). Specifically, the support member (200) may be formed on the lower surface of the outer frame (100) to form a step in the inner direction of the outer frame (100).

[0072] More specifically, the support member (200) may be formed to protrude in a direction perpendicular to the lower surface of the mounting member (110), and a stepped step may be formed inwardly with respect to the edge of the mounting member (110). The step formed by the support member (200) with respect to the mounting member (110) allows the battery transport tray (10) to pass over the colliding roller through the stepped step even if the lower part of the tray collides with the roller when the tray is transported via a roller conveyor.

[0073] In the support member (200), a corresponding hole (210) may be formed at a position corresponding to the heat dissipation hole (111) and mounting hole (112) formed in the mounting member (110), or in a shape larger than the size of the heat dissipation hole (111) and mounting hole (112). The corresponding hole (210) can induce liquid and gas discharged during the activation process of batteries introduced into the internal space of the outer frame (100) to be discharged to the outside of the tray (10) through the heat dissipation hole (111), and can cool the batteries by dissipating heat when the batteries are repeatedly charged and discharged and generate heat.

[0074] Additionally, a corresponding hole (210) formed at a position corresponding to the position of the mounting hole (112) is formed to be larger than the size of the mounting hole (112), so that a fastening unit such as a bolt head or nut can be inserted, and the fastening unit can pass through the mounting hole (112) and fasten the mounting part (110) and the inner frame (400).

[0075] Referring to FIGS. 5 and 6, the inclined unit (300) is an inclined surface formed at the step between the lower surface of the outer frame (100) and the outer surface of the support member (200). When a battery transport tray (10) is transported by a roller conveyor, if a collision occurs between the roller and the lower part of the tray (10), the inclined unit (300) and the roller come into contact to disperse and cushion the impact caused by the collision, and the tray (10) can move over the collided roller through the inclined surface of the inclined unit (300).

[0076] Multiple inclined units (300) may be formed at each step between each outer surface of the support member (200) and the lower surface of the outer frame (100). Alternatively, multiple inclined units (300) may be formed along the edge of the support member (200). Accordingly, even if there is a change in the direction of transport while the battery transport tray (10) is being transported by the roller conveyor, collisions with the rollers can be cushioned in all directions.

[0077] The inclination unit (300) may include a first inclination section (310) and a second inclination section (320). Accordingly, the inclination unit (300) may be configured to cushion the impact caused by collision with the roller from various directions when the roller conveyor moves.

[0078] 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 refer to the area near the corner of the lower end of the outer surface of the support portion (200).

[0079] The first inclined section (310) can most effectively cushion the impact when the outer surface of the support section (200) of the battery transfer tray (10) collides head-on with the roller, and the effect of cushioning the impact may be reduced when the outer surface of the support section (200) collides obliquely with the roller forming a predetermined angle. Accordingly, the first inclined section (310) can effectively cushion the impact even when the outer surface of the support section (200) collides obliquely with the roller forming a predetermined angle by including a curved shape on the outer surface.

[0080] The curved shape included in the first inclined portion (310) may be a shape that is convex upward with respect to the inclined surface, and may be formed symmetrically in both directions with respect to a central axis formed along the length direction of the first inclined portion (310).

[0081] The curved shape included in the first inclined section (310) can be formed so that it can be smoothly connected to each other at the boundary between the first inclined section (310) and the second inclined section (320) formed on both sides of the first inclined section (310).

[0082] The inclination angle of the first inclined portion (310) can be formed at an angle of 10° to 30° with respect to the lower surface of the outer frame (100).

[0083] The second inclined section (320) may be an inclined surface formed on both sides of the first inclined section (310) and sloped in a direction away from the first inclined section (310). That is, the second inclined section (320) may be formed in a diagonal direction or a direction perpendicular to the slope direction of the first inclined section (310). The second inclined section (320) may be formed longer in the direction of both sides of the first inclined section (310) than the width of the first inclined section (310). The second inclined section may be formed in a flat shape.

[0084] 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 roller of the roller conveyor collide at an angle forming a predetermined angle, and allows the tray (10) to move over the collided roller through the inclined surface of the second inclined section (320).

[0085] The first inclined section (310) and the second inclined section (320) of the inclined unit (300) can effectively disperse the impact when the battery transport tray (10) moves along the roller conveyor, not only when the outer surface of the support member (200) collides head-on with the roller, but also when it collides obliquely at a predetermined angle, thereby minimizing the impact that the batteries stored inside the battery transport tray (10) may receive.

[0087] Second embodiment

[0088] As a second embodiment of the present invention, with reference to FIG. 2, the battery transfer tray (10) assembly of the present invention may include a battery transfer tray (10) and a plurality of inner frames (400) mounted on the battery transfer tray (10). The battery transfer tray (10) may include an outer frame (100), a support member (200), and an inclined unit (300), and a detailed description thereof may be substituted with the contents 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 mounted to the mounting member (110) of the battery transfer tray (10) through a fastening unit.

[0089] Multiple inner frames (400) may be provided, and multiple partition plates (410) may be arranged at predetermined intervals along the longitudinal direction of the inner frame (400). Multiple batteries are arranged between each partition plate (410) and adjacent partition plates (410), and can be stably supported by being erected by the partition plates (410). Multiple inner frames (400) may be positioned symmetrically on the mounting portion (110). The inner frame (400) may be mounted on the mounting portion (110) by fastening a fastening unit, such as a bolt and nut, to the fastening portion (420).

[0091] Although the present technology has been described through the above embodiments, the present technology is not limited thereto. The above embodiments may be modified or changed without departing from the spirit and scope of the present technology, and a person skilled in the art will understand that such modifications and changes are also within the scope of the present technology.
