Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims priority and benefit of Korean Patent Application No. 10-2021-0163294 , filed November 24, 2021 and is hereby incorporated by reference as fully set forth herein.

BACKGROUND

FIELD OF REVELATION

The present disclosure relates to a device, in particular a conveyor device, used for sealing a battery or a battery part.

DISCUSSION OF THE PRIOR ART

The content described in this section merely provides background information related to the present disclosure and does not constitute prior art.

With growing interest in environmental protection, efforts to reduce carbon emissions are spreading around the world. Conventionally, in order to reduce carbon emissions, production of vehicles with an internal combustion engine that generates its power by burning fossil fuels is continuously decreasing, while production of electric vehicles that obtain energy from electricity is continuously increasing.

The demand for batteries mounted in or on these electric vehicles to store electricity is constantly increasing. Meanwhile, the demand for batteries to power mobile devices is also increasing as the use of personal mobile devices such as smartphones and tablets has become commonplace.

With the increasing demand for batteries, research and development of batteries is actively promoted.

A battery may include a main body and an electrode mounted in or on the main body. The electrode can be provided as a positive electrode and a negative electrode. A gap may occur or arise between the main body and the electrode at a portion where the electrode is attached in/on the battery, i.e., at an electrode portion. Because contents inside the main body (e.g., an electrolytic solution) might flow out through the gap, it may be necessary to close the gap.

Consequently, in a production process of the battery, a process of sealing the electrode portion can be performed. The capping process can be performed by a conveyor having a capping function.

In such a conveyor, a pair of belts are spaced apart, for example, by a distance (e.g., a pitch, a distance, a spacing, or an interval) and arranged to rotate. A battery can be inserted between the straps prior to the closure process. The battery can then be pressurized and heated while being moved by rotation of the belt.

The belt may need to be replaced periodically because it is used under high pressure conditions. In order to replace the belt, it may be necessary to increase the distance (e.g., a separation distance or interval) between the pair of belts. For this purpose it may be necessary to carry out a dismantling process in which at least part of the conveyor device is dismantled and/or some parts of the conveyor device are moved.

When the belt is replaced by disassembling the conveyor and reassembling the conveyor, parts of the conveyor may hit or be hit by other parts. As a result, the parts of the conveyor may become worn or damaged, and the durability of the conveyor may deteriorate.

In addition, since disassembling and reassembling operations of the conveyor go through a process of disassembling and reassembling multiple parts, a structure that can shorten the time required for performing the operations is required.

SUMMARY OF REVELATION

Accordingly, the present disclosure is directed to providing a device, particularly a conveyor device, for sealing a battery or a battery part with a structure that can reduce an impact between parts when a belt is replaced.

Furthermore, the present disclosure deals with the provision of a device, in particular a conveyor device, for sealing a battery or a battery part with a structure structure that can shorten the time required for the operation by simply performing disassembly and reassembly.

The objects of the present disclosure are not limited to the objects described above, and other objects and advantages of the present disclosure not mentioned can be understood by the following description and can be understood more clearly by examples of the present disclosure. Furthermore, it is readily apparent that the objects and advantages of the present disclosure can be attained by any means described in the claims and any combination thereof.

The present disclosure provides an apparatus according to claim 1 for sealing a battery or battery pack. Examples thereof are set out in the dependent claims.

The device (e.g. device or system) for sealing a battery or a battery part according to the present disclosure serves (e.g. can be designed for) the sealing of a battery or a battery part (in particular a battery cell). For example, the device may be configured to close (e.g., close and/or hermetically or impermeably seal) a gap between an electrode and a main body of the battery or battery pack.

In the following, for the sake of brevity, only the term "battery part" is used when referring to the battery or the battery part. The term "battery part" is therefore to be understood in such a way that it includes both a part of a battery, such as a battery cell, and an (entire) battery.

The device comprises a first conveyor unit and a second conveyor unit, which together can also be referred to as the “conveyor unit” of the device. The device according to the present disclosure can thus also be referred to as a conveying device. The first and the second conveyor unit can each comprise a means for moving the battery pack. In particular, the first and the second conveyor unit can each comprise a belt for moving the battery part, for example as described below. In other examples, the first and/or second conveyor unit may not include a belt, but may be configured to receive, carry, and/or drive a belt, for example. Additionally or alternatively, the first and the second conveyor unit can also comprise other means for moving the battery part, such as a roller conveyor and/or a movable floor.

The first and the second conveyor unit can be arranged facing each other, for example separated or spaced apart by a gap for arranging the battery part. The first and the second conveying unit can be configured to seal the battery part between them. The first and the second conveyor unit can, for example, each comprise means for heating and/or for exerting pressure on the battery part in order to carry out the closing process, in particular while the battery part is being moved. In some examples, the means for moving the battery pack (such as the straps) may also be configured to heat and/or apply pressure to the battery pack, for example by generating the heat and/or the pressure and/or by conducting or transferring the heat and/or the pressure to or on the battery pack.

The device also includes a first drive shaft for driving the first conveyor unit. The first drive shaft is adapted to be coupled to a drive motor for rotating the first drive shaft, for example, directly connected or indirectly via a drive member, such as the first drive member, as described below. The first drive shaft can be adapted to drive a means for moving the battery part of the first conveyor unit, for example to move a belt or to operate a roller conveyor by rotation of the first drive shaft. The first drive shaft may be fixed, i.e. it may not be movable, other than being adapted to rotate (e.g. by being rotated by the drive motor). In particular, the first drive shaft cannot move when a distance is set between the first and the second conveying unit.

The device also includes a second drive shaft for driving the second conveyor unit, for example similar to the first drive shaft described above. The second drive shaft is configured to partially move relative to the first drive shaft (e.g., comprising one or more parts and/or components configured to move) to allow adjustment of a spacing between the first and second conveyor units (e.g. to provide sufficient clearance to allow the first and second conveyor units to move relative to each other, e.g. by applying an external force). For example, the second drive shaft may be configured to move partially along a first direction that extends across a gap between the first ten and the second conveying unit or spans them (e.g. at an angle, and in particular perpendicularly, to a surface of the second conveying unit facing the first conveying unit across the gap). The first direction can run at an angle and in particular perpendicular to an axis or longitudinal direction (for example an axis of rotation) of the second drive shaft. The second drive shaft (for example the moving parts/components thereof) can for example partially move a distance of between 2 mm and 100 mm, in some examples between 5 mm and 50 mm, in one example between 10 mm and 30 mm, ie to enable the spacing between the first and second conveyor units to be adjusted by a corresponding distance. Adjusting the spacing may, for example, allow for the accommodation of battery parts of different sizes and/or improved access to components of the device, such as the first and second conveyor units, for example to service and/or replace parts thereof, such as a belt or a roller conveyor.

The device further includes a second drive member coupled to the second drive shaft. The second drive member is configured to engage (e.g., by engagement) with an actuator coupled to the drive motor for rotating the second drive shaft (e.g., to transmit rotary motion, e.g., torque or rotational force, from the actuator to the second drive shaft). grasp. The actuating part may be included in (i.e. part of) the device or it may be an external part, for example provided together with an external drive motor. In some examples, the second drive member may be engaged (e.g., in contact) with the actuating portion. The second drive member may be coupled to the second drive shaft such that the second drive member rotates with the second drive shaft (i.e., the second drive member may rotate when the second drive shaft rotates and/or vice versa). The second drive element may be arranged (e.g. mounted) on the second drive shaft and/or connected or attached thereto. In some examples, the second drive member, the second drive shaft, or a portion thereof (e.g., the first member, as described below) may be formed as a single piece. The second drive element and/or the actuating part can be or can comprise, for example, a toothed wheel, a worm shaft or a set screw and/or any other suitable gear or transmission element known in the art.

The second drive shaft includes three or more members, namely at least a first member, a second member and a third member. Each of the members may be, for example, or include a shaft portion, such as a cylindrical shaft portion.

The first member is coupled to (eg, attached to) the second drive member. The first member may be fixed, i.e. it may be immovable (i.e. rotatably fixed) other than being adapted to rotate about its axis (e.g. by being rotated by the drive motor).

The second member is adapted to move relative to the first member to partially move the second drive shaft (e.g. at least the second member thereof) relative to the first drive shaft. For example, the second member may be adapted to move along the first direction and/or at an angle, in particular perpendicular to an axis or longitudinal direction (e.g. an axis of rotation) of the first and/or the second member. The second link can be designed to move without tilting, i.e. its axis of rotation can remain parallel to its original orientation. In some examples, the axis of rotation of the second member may always be parallel to the axis of rotation of the first member.

The third member (e.g. both ends thereof) is coupled to the first and second members, respectively. The third link may be disposed between the first and second links and it may connect the first and second links (e.g. for transmitting rotary motion between them, eg for driving (e.g. rotating) the second link by rotation of the first link). The third member is configured to tilt relative to the first member and the second member as the second member moves relative to the first member (e.g., in accordance with movement of the second member relative to the first member). Thereby the third link can allow the second link to move relative to the first link. The third member may be adapted to tilt (e.g. rotate through a tilt angle of less than 360°) about an axis that is at an angle, in particular perpendicular to an axis of the first and/or the second member. For example, the third member may be configured to incline at an angle between 2° and 90°, in some examples between 5° and 45°, in one example between 10° and 20°. The third member can have a length between 10 mm and 500 mm, in some examples between 20 mm and 400 mm, in an example between 100 mm and 300 mm.

The third link may be configured to transmit rotational motion between the first link and the second link at at least one tilt angle, in some examples at some tilt angles (e.g., at one or more ranges of tilt angles), in one example at all tilt angles. The third link can be coupled to the third link by a corresponding joint, which allows tilting and the transmission of the rotational movement. In some examples, one or both of the joints may be a universal joint (also referred to as a U-joint or cardan joint). For example, a universal joint may be or include a pair of hinges perpendicular to one another and connected by a connecting member such as a cross shaft.

In some examples, the third member may be configured to adjust its length by, for example, extending and/or retracting. In particular, the third link may be adapted to adjust its length as the second link moves relative to the first link, for example such that the second link does not move along its axis of rotation (i.e. only perpendicular to its axis of rotation). In one example, the third member may be configured to increase its length by at least 1%, in some examples by at least 3%, in some examples by at least 5%, in one example by at least 10%, and in one example by at least 20% of its to increase the minimum length.

The device may further include a first drive member coupled to the first drive shaft. The first drive member can rotate with the first drive shaft (i.e., the first drive member can rotate when the first drive shaft rotates and/or vice versa). The first drive element can be arranged, for example, on (e.g. mounted on) and/or connected to or attached to the first drive shaft. The first drive element can be designed, for example, as described above for the second drive element. In some examples, the first drive member may be configured to be coupled to the drive motor (e.g., directly connected or indirectly coupled via one or more other drive members) to rotate the first drive shaft.

The first drive element can be the operating part, which the second drive element is designed to engage with. In other words: the first drive element can be designed to drive the second drive element and thus the second drive shaft (for example to transmit a rotational movement thereto). For example, the first drive member may be coupled to the motor (e.g., directly or via the first drive shaft and/or one or more other drive members) and may transmit rotary motion from the motor to the second drive member to rotate the second drive shaft.

In some examples, one or both of the first drive member and the second drive member is or includes a first gear or a second gear, particularly a first/second gear that together (e.g., fixedly coupled or attached) rotates with the respective drive shaft.

In some examples, the device may include the drive motor. The drive motor can be an electric motor, for example. The drive motor can be connected to the first drive shaft. The first drive shaft can be connected (e.g. directly connected) to a drive gear wheel of the drive motor, for example. In other examples, the drive motor may be connected to the second drive shaft. The second drive shaft can be connected to the drive gear of the drive motor, for example.

The device may further include a first frame. The first frame may be adapted to support (e.g. hold) and/or drive the first conveyor unit or part thereof. The first frame may comprise one or more parts or elements adapted to rotate (e.g. they may be rotatably arranged or mounted and/or they may be rotated by the drive motor). The first frame can in particular include or be the first drive shaft and/or the first drive element. Additionally or alternatively, the first frame may comprise one or more fixed parts or elements that are not designed to rotate, for example one or more support elements for supporting and/or (rotatably) supporting the first conveyor unit and/or rotatable parts or elements of the frame, for example one or more brackets and/or one or more bearings.

Additionally or alternatively, the device can comprise a second frame. The second frame may be adapted to support (e.g. hold) and/or drive the second conveyor unit or part thereof. The second frame can, as above for the first frame men described, executed. The second frame can in particular include or be the second drive shaft and/or the second drive element.

In some examples, the second frame is arranged above the first frame (e.g., along a vertical or gravitational direction). Additionally or alternatively, the second frame may be provided so that it can at least partially rise and fall (e.g. move up and down), for example with one or more parts that move up and down (e.g. at least a part or member of the second drive shaft). The first and the second conveyor unit can be provided in and/or on the first and the second frame, respectively.

In one example, the device includes the drive motor; the first frame having the first drive shaft connected to the drive motor and the first gear (e.g. as an example of a first drive member) coupled to the first drive shaft and rotating together with the first drive shaft; the second frame with the second drive shaft and the second gear (e.g. as an example of a second drive element), the second frame being arranged above (e.g. arranged on top) the first frame and being provided to partially (e.g. by a member is provided) to move up and down (e.g. raise and lower) the second gear coupled to the second drive shaft and meshing with the first gear to transmit rotary power to the second drive shaft; and a conveyor unit provided (eg, arranged) in and/or on each of the first frame and the second frame. The second driveshaft may include a first member to which the second gear is coupled, a second member configured to move up and down relative to the first member (e.g., be raisable and lowerable), and a third member , which is respectively coupled to the first limb and the second limb (e.g. coupled to both ends) and rotates relative to the first limb and the second limb when the second limb moves up and down (e.g. in accordance with lifting and lowering of the second link).

In some examples, the device may further include a first attachment structure and/or a second attachment structure. The first attachment structure may, for example, be adapted to mount (e.g. receive) the first frame and/or the first conveyor unit (or a part thereof) therein and/or thereon, for example by arranging and/or attaching the first frame and/or the first conveyor unit in and/or on the first attachment structure. The second attachment structure may, for example, be adapted for mounting (e.g. receiving) the second frame and/or the second conveyor unit (or a part thereof) therein and/or onto it, for example by arranging and/or attaching the second frame and/or the second Conveyor unit in and / or on the second attachment structure. In some examples, one or both of the first and second attachment structures may be or include a plate. The first and the second fastening structure can thus also be referred to below as the first or second plate.

The first mounting structure (e.g., the first plate) may be rotatably coupled to the first frame (e.g., such that the first frame or a portion thereof may rotate relative to the first mounting structure). The first attachment structure may be designed not to rotate, for example it may be fixed at least along the axis of rotation of the first and/or second drive shaft. In some examples, the first attachment structure may be fixed along either direction (i.e., may not be moveable at all).

The second attachment structure (e.g., second plate) may be disposed (or attached) over the first attachment structure. The second mounting structure may be rotatably coupled to the second frame (e.g., such that the second frame or a portion thereof may rotate relative to the second mounting structure). The second mounting structure may not be designed to rotate, for example it may be fixed at least along the axis of rotation of the first and/or second drive shaft. The second attachment structure may be configured to move relative to the first attachment structure, for example along the first direction, to allow adjustment of a spacing between the first and second conveyor units.

In some examples, the first attachment structure or portion and the first frame or portion may be embodied as a common structure or member. In some examples, the second attachment structure or portion and the second frame or portion may be embodied as a common structure or member.

In some examples, the device may further include a support structure adapted therefor is to support the first conveyor unit, for example to bear or hold at least part of the weight of the first conveyor unit. The support structure can be designed, for example, to support the first conveyor unit via the first fastening structure and/or via the first frame. The support structure may include a base unit (e.g., a pedestal or base plate) and a bracket for holding the first conveyor unit. The bracket may be pivotally coupled to the base unit, for example by a hinge. For example, the retaining bracket may be adapted to be brought into contact with the first attachment structure and/or the first frame, for example by pivoting the retaining bracket relative to the base unit.

In some examples, the headband may have a distal portion (e.g., a portion remote from the hinge that couples the headband to the base unit, e.g., located at an end of the headband opposite the hinge). The distal portion may be provided to support the first delivery assembly (e.g., to be brought into contact with the first attachment structure and/or the first frame). The headband may be configured to be deployed from the base unit by an external force, such as by pivoting the headband from a first configuration in which the distal end is spaced from the first attachment structure and/or the first frame (and, for example, is attached to the base unit adjacent) to a second configuration in which the distal end is in contact with and supports the first attachment structure and/or the first frame(s). The headband may also be adapted to be folded back toward the base unit (i.e., back to the first configuration from the second configuration) by an external force.

In one example, the device may include a base (e.g., as an example of a base unit of a support structure configured to support the first panel, and a bracket rotatably coupled to the base and one end of which holds the first panel .

In one example, the bracket may have an upper end provided to support a bottom surface of the first panel (e.g., as an example of a first attachment structure). The support bracket may be provided spaced apart from the first plate by rotating relative to the pedestal (e.g. as an example for a base unit of a support structure) by an external force.

The apparatus may further comprise a gap block adapted to be inserted into a gap between the first conveyor unit and the second conveyor unit, for example to separate the first and second conveyor units by a predetermined distance or distance. For example, the splitting block may be configured to be inserted between the first and second attachment structures and/or between the first and second frames. The predetermined distance may be determined by a thickness (or height) of the splitting block, for example.

In one example, the device can include a gap block that can be inserted into a gap between the first panel (e.g., as an example of a first attachment structure) and the second panel (e.g., as an example of a second attachment structure) to fill the gap between the separate the first disk and the second disk by a given (e.g. predetermined) value.

In some examples, one or both of the first and second conveyor units may each include a drive roller mounted on the first drive shaft and the second drive shaft, respectively. The drive roller can be designed to rotate together with the respective drive shaft. One or both of the first and second conveyor units may comprise a belt wrapped around the drive pulley, the drive pulley being adapted to move the belt by rotating the drive pulley. The strap may be configured to move the battery pack, for example moving the battery pack along a direction of movement of the strap. Additionally or alternatively, the strap may be configured to seal the battery pack, for example by applying (e.g. transferring) heat and/or pressure thereto.

In some examples, one or both of the first and second conveyor units may each include one or more idlers (e.g., a pair of idlers) configured to apply tension and/or pressure to the belt (e.g., to apply pressure to a battery pack/a to let force work on it). The pair of tension rollers can be arranged, for example, on opposite sides of the drive roller. The one or more idler pulleys may be arranged such that the idler pulleys are in contact with the belt. In some examples, the one or more idlers may be configured to apply tension to the belt by adjusting (e.g., increasing) a length of a path along which the belt extends and/or moves. for example to stretch or lengthen the belt. Additionally or alternatively, the one or more idler pulleys may be configured to apply pressure to the belt by pushing and/or pressing against the belt. The idler pulleys may be designed to adjust tension and/or pressure applied to the belt. To this end, the one or more tension rollers can be configured, for example, to move relative to the belt, for example perpendicular to a surface of the belt.

Additionally or alternatively, one or both of the first and second conveyor units may each comprise one or more idler rollers (or idler rollers; e.g. a pair of idler rollers) around which the belt is wrapped. The one or more rollers do not have to be actuated, for example they do not have to be driven by the drive motor, but they can for example be free-wheeling. The idlers may define a path along which the belt extends and/or moves.

In one example, the conveyor unit may include a movable pulley mounted on the first drive shaft and the second drive shaft, a belt wrapped around the movable pulley and moved (e.g. rotated) by rotation of the movable pulley, a pair of idler pulleys, arranged on either side of the movable pulleys and adapted to apply tension and/or compression (pressure) to the belt, and a pair of idler pulleys spaced apart from the tension pulley and around which the belt is wound.

The apparatus may further comprise a tension/pressure adjustment unit (tension/pressure control section) adapted to move one or both of the tension rollers of the first conveyor unit and/or one or both of the tension rollers of the second conveyor unit to tension the and/or or adjust the force on the belt of the respective conveyor unit. The tension/pressure adjustment unit may, for example, comprise or be designed to control an actuator for moving the respective tension rollers.

In one example, the second plate (e.g., as an example of a second attachment structure) may include an idler guide disposed and mounted over (e.g., located on top) the belt to bring the idler roller into contact with the belt, and the idler guide may include a tension/pressure adjustment unit configured to move the idler up and down (e.g., raise and lower the idler).

The tension/pressure adjustment unit may be provided as (e.g. comprising or formed as) a tension/pressure adjustment cylinder (tension cylinder) adapted to move (e.g. up and down/raise and lower) one or both of the respective tension rollers ), for example by pneumatic and/or hydraulic pressure. Additionally or alternatively, the tension/pressure adjustment unit may be provided as (e.g. comprise or be formed as) a height adjustment device (e.g. a raise and lowering adjustment device) adapted to move one or both of the idler pulleys (e.g. up and down/to lift and lowering) by means of a helical rotation (e.g. in a helical turning method). For example, the height adjustment device may be adapted to move the respective idler pulleys by rotating a nut member relative to a screw member. In some examples, the tension/compression unit may include two or more tension/compression cylinders and/or two or more height adjustment devices.

In some examples, the idlers are configured to adjust a range of a portion of the belt that moves linearly (linearly moving portion), for example by adjusting a length of the portion of the belt that moves linearly. For example, the linearly moving portion may be a flat or planar (e.g., not curved or curved) portion of the belt. In the linearly moving section, the belt can move along a straight line (e.g. in the plane of the linearly moving section). The section can be arranged between the rollers, for example extending from a first of the rollers to the other roller. The portion may be arranged to come into contact with the battery part, for example facing the other conveyor unit and in particular a linearly moving portion thereof. For example, the casters may be configured to move to adjust a distance between the casters to adjust the range (e.g., length) of the linearly moving portion.

The idler pulleys may be arranged at positions corresponding to the movable pulley and the tension pulley, for example, in a direction perpendicular to the direction of movement of the belt. In other words, the rollers can be placed on the movable roller and the tension roller in the direction perpendicular to the direction of movement of the belt, for example such that a path along which the belt extends and/or moves lies in a plane perpendicular to the direction. The rollers can be arranged at a distance from the tension roller(s).

The device may comprise a (second) mounting structure in and/or on which the second conveyor unit is mounted, for example as described above. Some or all of the drive pulley, belt, idler pulleys, and idler pulleys of the second conveyor unit may be configured to move together when the mounting structure moves. For example, the respective elements may be rotatably coupled to the mounting structure (e.g. via a bearing) such that the respective elements can rotate relative to the mounting structure but move together with the mounting structure when the mounting structure is moved.

In one example, the movable pulley, belt, idler pulley, and idler pulley provided corresponding to the second drive shaft may be moved upward together as the second plate (e.g., as an example of a second attachment structure) moves upward.

The device according to an example may further comprise an enclosure (e.g. a box or housing) in which the first drive element (e.g. first gear) and/or the second drive element (e.g. second gear) is/are housed.

The device may further comprise an extensible cylinder (e.g. a hydraulically and/or pneumatically extensible cylinder) adapted to move the second conveyor unit relative to the first conveyor unit. In particular, the extensible cylinder may be adapted to move the second conveyor unit by moving the second mounting structure (e.g. the second plate) in and/or on which the second conveyor unit is mounted. The extendable cylinder may be a lift cylinder, for example an extendable cylinder configured to raise and lower the second conveyor unit (e.g. by raising and lowering the second mounting structure).

In some examples, the extendable cylinder, or a portion thereof, may be mounted within the canister. The second conveyor unit can be designed to be moved relative to the container. For example, the second attachment structure can be designed to be moved relative to the receptacle for moving the second delivery unit.

In one example, the device includes a lift cylinder mounted in the receptacle and configured to move the second panel up and down (e.g., as an example of a second attachment structure), the second panel being up and down relative to the receptacle is provided from movable.

The first link, the second link and the third link (e.g. the axes or longitudinal directions thereof) can be arranged parallel to each other and in particular along a straight line when the distance between the first and the second conveyor unit has a first value. In some examples, this configuration may be a normal usage (operational) configuration of the device. For example, the device can be designed to close the battery part when the distance between the first and the second conveyor unit has the first value, for example by driving the first and the second conveyor unit by rotating the first and/or the second drive shaft. In an example, the first value is a minimum distance (e.g. as small as possible) between the first and the second conveyor unit.

When the distance between the first and second conveyor unit has a second value, the third member can be inclined relative to the first member and the second member (for example, its axis or longitudinal direction can be at an angle to the axes or longitudinal directions of the first and second limb lying). In some examples, this configuration may be a maintenance or servicing configuration of the device. The first and the second conveyor unit or parts thereof can, for example, be accessible to a user or operator of the device in the maintenance/maintenance configuration. The second value can be, for example, a maximum (for example, the greatest possible) distance between the first and the second conveyor unit.

In one example, the first member, the second member, and the third member may be aligned in a same direction (e.g., side by side in the same direction) when the second drive shaft rotates (e.g., is rotated). When the second drive shaft moves upward (e.g. when the second plate is lifted), the third link can be arranged so that its longitudinal direction is inclined relative to the longitudinal directions of the first link and the second link.

In a device according to the present disclosure, an operating part, such as a first driving member (e.g., a first gear) and a second driving member (e.g., a second gear) engaged with the operated part, may maintain the engagement even then (e.g. in stay in contact with each other) when a part of the device moves (e.g. up) to replace a belt. Consequently, an impact between the operating part (e.g., the first driving member) and the second driving member, which would otherwise occur in a process in which the operating part and the second driving member are separated from each other and come into contact with each other again, thus does not occur. Consequently, it may be possible to effectively suppress the operating part and the second driving member from being worn and/or damaged by the impact.

Furthermore, a separate operation for separating and then re-engaging the operating part and the second drive member is not required. Consequently, it may be possible to greatly reduce the belt replacement time.

As a result, it may be possible to improve the durability of the device and greatly reduce the time and effort required to replace the belt.

Furthermore, in the device according to the present disclosure, it may be possible to measure a distance (e.g. a separation distance, such as a vertical separation distance) between a first conveyor unit and a second conveyor unit (e.g. between a first fastening structure, such as a first plate, and a second Fixing structure, such as a second plate) using a gap block, whereby, for example, the distance between a pair of belts can be easily adjusted.

Further, in the device according to the present disclosure, a user can bring a bracket into contact with the first attachment structure (e.g., the first plate) or detach the bracket from the first attachment structure by simply applying an external force to pivot/rotate the bracket relative to a base unit Separate support structure, such as a pedestal.

Consequently, since it may be unnecessary due to a structure of the bracket to perform an operation of disassembling or reassembling a coupling mechanism for coupling the bracket and the first attachment structure when the belt is replaced, it may be possible to improve the efficiency of the belt replacement operation.

Specific effects of the present disclosure along with the above-described effects will be described collectively, while specific elements for carrying out the present disclosure will be described below.

3 14 is a perspective view showing a device for sealing a battery or a battery pack according to an example of the present disclosure. For the sake of clarity, in 3 no belt 420 shown.

First, a device for sealing a battery or a battery part according to an example of the present disclosure is described with reference to FIG 3 and then problems of general (e.g. conventional) conveying devices will be described with reference to FIG 1 and 2 described.

The device for sealing a battery or a battery part according to the present disclosure can be used, for example, for sealing an electrode portion of a battery or a battery part by applying pressure (for example, applying pressure) and heating the battery or the battery part. In the following, for the sake of brevity, only the term "battery part" is used when referring to the battery or the battery part. The term "battery part" is therefore to be understood in such a way that it includes both a part of a battery, such as a battery cell, and an (entire) battery.

In the example in 3 the device can comprise a drive motor 100, a first frame 200, a second frame 300 and a conveyor unit 400. The device can therefore be referred to below as a conveying device.

The driving motor 100 can provide a driving force for driving the conveyor unit 400 . The conveyor unit 400 comprises a first conveyor unit and a second conveyor unit each having a respective belt 420 (in 3 not shown). The conveyance unit 400 is operated by the operation of the drive motor 100 . A battery pack inserted between the pair of straps 420 may be sealed by subjecting it to pressure (e.g., pressurizing) and heating it while being moved by the pair of straps 420 .

The battery pack can be pressurized by the pair of straps 420 . A separate heater adapted to heat the battery pack for sealing may also be provided in the conveyor.

The first frame 200 can be configured to support and/or drive the first conveyor unit. The first frame 200 may include a first drive shaft 210 connected to the drive motor 100 and a first drive member, in this example a first gear 220, coupled to the first drive shaft 210 and rotating together with the first drive shaft 210. The first frame 200 may be directly connected to the drive motor 100 and rotated by receiving a driving force from the drive motor 100, such as torque generated by the drive motor 100.

The second frame 300 can be configured to support and/or drive the second conveyor unit. In the example in 3 For example, the second frame 300 is arranged above the first frame 200 and has a part for moving up and down (ie it is provided so that it can rise and fall partially). The second frame 300 may include a second drive shaft 310 and a second drive member, in this example a second gear 320 coupled to the second drive shaft 310 . The second gear 320 meshes with an operating member coupled to the drive motor 100, namely the first gear 220 in the example in FIG 3 to transmit rotary motion (e.g., torque or rotary power) to the second drive shaft 310 .

The second gear 320 of the second frame 300 may be provided to mesh with the first gear 220 provided in the first frame 200 . Consequently, the second frame 300 can be driven by receiving the driving force from the first frame 200 .

The straps 420 can be mounted on the first frame 200 and the second frame 300, respectively. The pair of belts 420 mounted on the first frame 200 and the second frame 300 are spaced from each other (for example, vertically spaced). Thus, a gap or separating space can be formed between the two belts 420 .

The battery part can be arranged (e.g. mounted) in the separation space. The battery pack can be locked during movement along the straps 420 . The pair of straps 420 may need to be replaced periodically because the straps 420 may become worn and/or damaged as the sealing operation is performed repeatedly.

Replacement of a belt 420 may require increasing the distance (e.g., the separation distance) between the two belts 420 (e.g., between linearly moving portions thereof, as described below). A part of the second frame 300 may be movable up and down. Consequently, when the belt 420 is to be replaced (and/or for other service and/or maintenance work), a portion of the first frame 200 can be moved upwards and thus the separation distance between the belts 420 can increase.

As described above, in the state where the (vertical) separation distance between the two belts 420 is increased, the belt 420 can be separated by pulling out the belt 420 from the conveyor through a gap (for example, a vertical gap) between the first frame 200 and the second frame 300 and inserting a new belt 420 into the conveyor.

The conveyor device 400 can be arranged in and/or on the first frame 200 and the second frame 300 respectively. Thus, a pair of conveyor units 400 (i.e., the first and second conveyor units) disposed in and/or on the first frame 200 and the second frame 300, respectively, are provided. In some examples, the pair of conveyor units 400 may have a mutually symmetrical shape and may be arranged at symmetrical positions. The pair of conveyor units 400 can, for example, be mirror-symmetrical to a plane in which the battery part is to be arranged and/or moved.

The conveying unit 400 (for example, each of the first and second conveying units) may include a drive pulley (movable pulley) 410, the belt 420, an idler pulley 430, and an idler pulley 440.

The drive pulley 410 may be mounted on the first and second frames 200, 300, namely on the first drive shaft 210 and the second drive shaft 310, respectively. The drive pulley 410 is mounted on the drive shaft to move or forward the belt 420 wound thereon to lead (e.g. turning). A pair of drive rollers 410 may be provided mounted on the first drive shaft 210 and the second drive shaft 310, respectively.

The belt 420 can be moved by rotating the drive pulley 410 . The idler pulley 430 and the idler pulley 440 can be rotated by the rotation of the belt 420 . For example, idler pulley 430 and idler pulley 440 may be freewheeling.

The belt 420 (see e.g 5 ) may be wrapped around the drive roller 410 and moved by the rotation of the drive roller 410. As described above, the battery pack can be inserted between the pair of straps 420 and when the strap 420 rotates, the battery pack can be locked while moving along the strap 420 .

A pair of idler pulleys 430 may be provided, provided on either side of the drive pulley 410 , and may apply tension and/or pressure (e.g., compressing) to the belt 420 . A pair of idlers 430 may be provided for each of the first drive shaft 210 and the second drive shaft 310 (i.e., the first and second conveyor units may each include a pair of idlers 430). Consequently, two pairs of idler rollers 430, i.e. a total of four idler rollers 430, can be provided.

The idler pulley 430 can be adjusted by pushing or pushing the belt 420 in a direction that traverses a direction of movement of the belt 420 (e.g. perpendicular thereto), for example in the example in FIG 3 in a substantially vertical direction, apply tension and/or pressure to the belt 420 (e.g., by increasing its tension and/or a force acting thereon). The tension of the strap 420 can be adjusted by the idler pulley 430 such that the strap 420 effectively applies pressure (e.g., applying pressure) to the battery pack to perform the locking operation. The idler pulley 430 can contact the belt 420 and can be rotated by the movement of the belt 420 .

A pair of idlers 440 spaced apart from idler pulley 430 may be provided. The belt 420 may wrap around the pair of idlers 440 . A pair of rollers 440 may be provided for each of the first drive shaft 210 and the second drive shaft 310 (i.e., the first and second conveyor units may each include a pair of rollers 440). Consequently, two pairs of rollers 440, i.e. a total of four rollers 440, can be provided.

The idler roller 440 may be provided in the conveyor device to adjust an area (e.g., a length) of a linearly moving portion (linear moving portion) of the belt 420 that crawls (e.g., rotates). The linearly moving portion may be a flat or planar portion of belt 420, for example. The belt 420 can advance along a straight line in the linearly moving section. The belt 420 may wrap around the pulley 440 . When the belt 420 moves (e.g., rotates), the pulley 440 can be rotated by the movement of the belt 420 .

The idler rollers 440 may be arranged at positions corresponding to (for example, aligned with) the drive roller 410 and the tension roller 430 in a direction perpendicular to the direction in which the belt 420 moves, as shown in FIG 3 illustrated. The idler rollers 440 may be spaced apart from the idler rollers 430 . Thus, the belt 420 (e.g. a portion thereof facing or opposed to the other belt 420) can be provided to move linearly at a portion between the idler rollers 440 spaced from each other, e.g. in a horizontal direction.

Further, the belt 420 may be wound around the idler roller 440 at a portion that comes into contact with the idler roller 440, and may be bent so that the belt 420 can be linearly moved again when the moving direction changes (for example, in a portion of the belt 420 that moves in a direction opposite to the direction in which the battery pack is moved by the belt 420)

The conveyor device can further comprise a first attachment structure for mounting the first frame 200 and thus the first conveyor unit, and a second attachment structure for mounting the second frame 300 and thus the second conveyor unit. In the example in 3 the first mounting structure is a first panel 500 and the second mounting structure is a second panel 600. The first frame 200 may be rotatably coupled to the first panel 500, for example such that the first frame 200 or a portion thereof is free to rotate while the first plate 500 remains stationary. The second plate 600 can be arranged over the first plate 500, as in FIG 3 illustrated. The second frame 300 may be rotatably coupled to the second platen 600, for example such that the second frame 300 or a portion thereof is free to rotate while the second platen 600 remains stationary.

The second plate 600 can also move up and down as the second frame 300 moves up and down (and vice versa). A distance or separation distance 1000 (e.g. a vertical separation distance) between the first plate 500 and the second plate 600 can be smaller than the (vertical) distance or separation distance between the pair of belts 420.

When the belt 420 is replaced, the belt 420 can be removed by disassembling part of the conveyor and moving the second plate 600 upwards, thereby increasing the vertical separation distance 1000 between the first plate 500 and the second plate 600 and the vertical separation distance of the pair of belts 420 , be replaced. The first plate 500 (and the frame 200 and the first conveyor unit) can be fixed, ie not movable.

With reference to 1 and 2 in the general (e.g. conventional) conveyor, when the second frame 300 moves up to replace the belt 420, the entire second frame 300 constituting an upper portion of the conveyor moves the (second) conveyor unit 400 positioned on the second frame 300 is mounted, and the second plate 600 on which the second frame 300 is mounted together upwards. Consequently, the second drive shaft 310 and the second gear 320 mounted on or forming the second frame 300 also move upward together.

At this time, when the second frame 300 moves up from a state of meshing with the first gear 220, the second gear 320 moves up with it, and is spaced from the first gear 220. FIG.

After the belt 420 is replaced, the second gear 320 can move down when the second frame 300 moves down again and come into contact with the first gear 220 again. At this time, the first gear 220 and the second gear 320 may abut or collide with each other when the first gear 220 and the second gear 320 come into contact with each other.

Further, the first gear 220 and the second gear 320 may not mesh smoothly, so that the second gear 320 can be rotated by receiving the driving force transmitted from the first gear 220 after the second gear 320 is moved down and is in contact with the first gear 220.

Consequently, a separate operation for engaging the first gear 220 and the second gear 320 so that the first gear 220 and the second gear 320 can rotate smoothly with each other may be required.

As a result, when the first gear 220 and the second gear 320 in the meshed state are separated from each other (for example, vertically separated) for replacement of the belt 420, and the first gear 220 and the second gear 320 are then engaged with each other again after the belt 420 has been replaced, wear and/or damage will occur due to impact between the first gear 220 and the second gear 320, thereby reducing the durability of the conveyor.

Furthermore, since a separate operation is required for meshing the first gear 200 with the second gear 320, the time and cost required for the capping operation may increase. Accordingly, the present disclosure proposes a structure that can solve at least some of these problems. This is described in detail below with reference to the drawings.

4 12 is a plan view showing part of the conveyor device according to an example of the present disclosure. 5 12 is a cross-sectional side view showing part of the conveyor device according to an example of the present disclosure.

In the conveyor device according to an example of the present disclosure, a universal joint structure may be provided on the second drive shaft 310 . The gimbal structure may be configured to allow movement of a portion of the second drive shaft (which, for example, may be adjacent to and/or in contact with the second conveyor unit) while another portion of the second drive shaft (which, for example, may be adjacent to the second gear 320 may be) remains stationary (i.e. without moving the other part of the second drive shaft). The second drive shaft 310 may include a first member 311, a second member 312, and a third member 313, for example. The first member 311, the second member 312 and the third member 313 may be connected together to function as the gimbal structure. For example, the gimbal structure may allow the second member 312 to move without moving the first member 311 .

The first member 311 can be coupled to the second member 320 . Consequently, since the second link 320 is fixedly coupled to the first link 311, the first link 311 can be rotated by receiving the driving force from the first gear 220. FIG.

The second member 312 can be provided to move up and down relative to the first member, for example to allow adjusting the distance between the first and second conveyor units. The second link 312 can be rotatably coupled to the second plate 600 e.g. such that the second member 312 is free to rotate relative to the second plate 600. When the second frame 300 and the second plate 600 move up and down, the second member 312 can move up and down together with the second frame 300 and the second plate 600 . The drive roller 41β may be carried by (e.g. mounted on) the second member 312 .

Two ends of the third link 313 may be coupled to the first link 311 and the second link 312, respectively. The third member 313 may be configured to be tilted relative to the first member 311 and the second member 312 as the second member 312 moves up and down. Both ends of the third link 313 may be pivotally coupled to ends of the first link 311 and the second link 312, respectively, for example by a respective universal joint. Consequently, when the second member 312 moves up and down, the third member 313 can be inclined relative to the first member 311 and the second member 312 .

6 12 is a view showing part of the second drive shaft 310 according to an example. 7 FIG. 14 is a view showing a state in which the second link 312 is moved from the second in 6 drive shaft 310 shown has been moved upwards.

6 FIG. 12 shows an arrangement state of the second drive shaft 310 when the conveyor device operates to close the battery pack (operating configuration). 7 12 shows an arrangement state of the second drive shaft 310 after the second plate 600 is moved up to replace the belt 420 (maintenance or maintenance configuration).

At the in 6 As shown, the second drive shaft 310 can be rotated by taking a longitudinal direction thereof as a rotation axis direction (ie, the longitudinal direction or axis of the second drive shaft 310 can coincide with the rotation axis). When the second drive shaft 310 rotates, the first link 311, the second link 312 and the third link 313 can be arranged parallel to each other and along a straight line (aligned side by side in the same direction).

At the in 7 As shown, ie, a state where the belt 420 is replaced, the second drive shaft 310 does not rotate, the second link 312 can move up, and at this time the second plate 600 can move up (or vice versa). Consequently, the third member 313 can be tilted relative to the first and second members 311, 312 in this configuration. In some examples, the joints or hinges that couple the third link 313 to the first and second links 311, 312 may be universal joints that also allow the second drive shaft 310 to rotate when the third link 313 is tilted (e.g., rotating the links 311,312,313 about their respective axes or longitudinal directions).

When the second platen 600 moves up, the drive pulley 410, the belt 420, the idler pulley 430 and the idler pulley 440 provided to correspond to the second drive shaft 310 (i.e. the second conveyor unit) may be provided together to move.

In other words, when the second plate 600 moves up, at least part of the second frame 300 and the second conveyor unit, in particular the second link 312, the drive pulley 410 mounted on the second link 312, and the belt can move 420 wound around the drive roller 410 move upwards.

When the second plate 600 moves upwards, the third member 313 may be arranged such that its longitudinal direction (axis) is inclined (e.g. obliquely or at an angle) relative to the longitudinal directions (axes) of the first member 311 and the second member 312 ). The second member 312 can be translated in parallel (ie without tilting the second member 312) as in FIG 6 , 7 shown. The third link 313 can pivot about the hinge that couples the third link 313 to the first link 311, also as in FIG 6 , 7 shown. In some examples, the third member 313 may be extensible, for example such that its length increases. This may, for example, allow the second link 312 to be prevented from moving along its axis when the third link 313 is tilted.

In other words, when the second platen 600 moves up as shown in FIG. As shown, the first member 312 and the third member 313 move, but the first member 311 does not move. Consequently, the second gear 320 mounted on the first member 311 does not move and can maintain the state of meshing with the gear 220 mounted on the first frame 200 .

Due to this structure, even if a part of the conveyor moves up to replace the belt 420, the first gear 220 and the second gear 320 can keep their meshing with each other (for example, they can keep in contact with each other). As a result, there is no shock between the first gear 220 and the second gear 320 shown in a process where the first gear 220 and the second gear 320 are separated from each other and then brought back into contact with each other. Consequently, it may be possible to effectively suppress the first gear 220 and the second gear 320 from being worn by the impact.

Further, a separate process of separating and then re-engaging the first gear 220 and the second gear 320 is not required. Consequently, it may be possible to greatly reduce the time for replacing the belt 420.

Consequently, it may be possible to improve the durability of the conveying device and greatly reduce the time and effort for replacing the belt 420.

Hereinafter, another configuration of the conveyor device according to an example of the present disclosure will be described in detail. The conveyor device according to one example may further include a tensioning guide 610 .

The tensioning guide 610 may be provided on or as part of the second attachment structure, for example the second plate 600 in this example. The tension guide 610 may be positioned (e.g., mounted) such that the tension pulley 430 contacts the belt 420 .

The tensioning guide 610 may be coupled to the second plate 600 (e.g., attached thereto or formed integrally therewith). The tensioning guide 600 may have a part which is arranged above the second plate 600, for example extending towards the second conveyor unit. The idler pulley 430 may be coupled to (e.g., attached to and/or supported by) the idler guide 610 to contact the belt 420 . The tension guide 610 may include a tension/pressure adjustment unit 611 for moving the tension pulley 430 up and down, for example to adjust a tension and/or pressure applied to the belt 420 .

When the tension/pressure adjustment unit 611 moves the idler pulley 430 downward, the idler pulley 430 may press and/or push (e.g., further pressurize) against the belt 420 to relieve the tension and/or force acting on the belt 420 , to increase. Conversely, when the tension/pressure adjustment unit 611 moves the tension roller 430 upwards, a force with which the tension roller presses and/or pushes against the belt 420 may decrease, and thus the tension and/or force acting on the belt 420 works, lose weight.

By moving the idler pulley 430 up and down to adjust the tension and/or the force acting on the belt 420, a compressive force applied to the battery part closed by the belt 420 can be adjusted accordingly.

In the example, since the pair of tension rollers 430 is provided to correspond to the second frame 300, a pair of tension guides 610 is also provided accordingly (for example, one for each tension roller 430), and there may also be a pair of tension/pressure adjustment units 611 disposed on each tension guide 610 may be provided (e.g., one for each idler pulley 430).

The tension/pressure adjustment unit 611 can be configured as a tension/pressure adjustment cylinder 6111 designed to move the idler up and down by pneumatic and/or hydraulic pressure and/or a height adjustment device 6112 designed to move the idler 430 to be moved up and down by means of a helical motion (e.g. by a helical turning method).

in the in 3 In the example shown, one clamping guide 610 is provided with the clamping cylinder 6111 and the other clamping guide 610 is provided with the height adjustment device 6112. In another example, the clamping cylinder 6111 can be provided on all of the pair of clamping guides 610 or the height adjustment device 6112 can be provided on all of the pair of clamping guides 610 .

The conveyor according to an example of the present disclosure may further include a receptacle 920 and an expandable cylinder, such as a lift cylinder 930 (e.g., for raising and lowering).

The first gear 220 and the second gear 320 can be housed in the case 920 . The case 920 can be provided in a box shape with an open top or face and the first gear 220 and the second gear 320 can be housed therein.

The lift cylinder 930 can be mounted in the receptacle 920 . The lift cylinder 930 can move the second plate 600 up and down. The lift cylinder 930 can be operated by pneumatic and/or hydraulic pressure, for example. When the second plate 600 is moved up and down by the lift cylinder 930, the first link 311 of the second drive shaft 310 and the second gear 320 mounted on the first link 311 do not move as described above, and thus the first Gear 220 and the second gear 320 when the belt 420 is replaced maintain the state of meshing.

The second plate 600 can be provided as movable (e.g. up and down) relative to the receptacle 920 . The case 920 can maintain the position without moving even if the second plate 600 moves up and down. In other words, even if the second plate 600 moves up and down, the case 920 accommodating the first gear 220 and the second gear 320 does not move, and thus the first gear 220 and the second gear 320 maintain the state of being engaged with each other. The container 920 can, for example, be fixed, for example on the first plate 500.

8th 12 is a perspective view showing part of the conveyor device according to an example of the present disclosure. 9 12 is a perspective view of the conveying device in FIG 8th 12 showing a state in which a retaining bracket is folded or retracted (e.g. rotated and laid down).

The conveyor device according to an example of the present disclosure may further include a splitting block 910 . The gap block 910 can be inserted into a gap between the first panel 500 and the second panel 600 . The gap block 910 can separate the gap between the first plate 500 and the second plate 600 by a set or predetermined value (e.g. to separate the first and second plates 500, 600 by a predetermined distance), for example to separate the first and the second conveyor unit (e.g. the belts 420) by a fixed or predetermined distance (e.g. such that the distance between them is a predetermined distance/value).

The “gap” mentioned above may refer to a space between (e.g. vertically spaced between) the first plate 500 and the second plate 600 and between the first and second conveying units (e.g. the belts 420), respectively, in a state where the Conveyor device performs the battery part closure process (e.g. in the operating configuration).

A plurality of gap blocks 910 may be provided. Each gap block 910 can be provided to be inserted into or removed from the gap between the first panel 500 and the second panel 600 by a user. As the gap (e.g., the vertical gap) between the first plate 500 and the second plate 600 increases, the distance (e.g., the vertical separation distance) between the pair of belts 420 can be increased.

The size and thickness of the battery pack that operates in the conveyor can vary. Consequently, in order to be able to seal battery parts of different shapes having different sizes and thicknesses in the same conveyor, it may be necessary to adjust the distance (e.g. the vertical separation distance) between the two belts 420.

In the example, the distance between the two straps 420 can be adjusted by adjusting the size or height (e.g., vertical distance) of the gap.

The gap block 910 can be inserted into the gap between the first panel 500 and the second panel 600 . The gap blocks 910 can be provided to have different heights or thicknesses (e.g., vertical thicknesses). Consequently, the gap blocks 910 having different thicknesses can be inserted into the gap between the first plate 500 and the second plate 600, and thus the size of the gap can be adjusted.

The thickness of the gap block 910 can be, for example, between 5 mm and 50 mm, in some examples between 10 mm and 20 mm, for example 10 mm, 15 mm, 20 mm, or the like. The user can set the gap between the first plate 500 and the second plate 600 to a fixed or predetermined value by inserting the gap block 910 having an appropriate thickness into the gap, considering the size and thickness of the battery pack.

Consequently, it is possible to maintain the state in which the two straps 420 are spaced apart by a distance (e.g., a vertical separation distance) of a fixed or predetermined value in accordance with each battery part.

In the example, the distance (eg, the vertical separation distance) between the first plate 500 and the second plate 600 can be adjusted using the gap block 910, and thus the distance (eg, the ver vertical separation distance) between the two belts 420 can be easily adjusted.

The conveyor device according to an example of the present disclosure may further include a support structure configured to support the first conveyor unit. The support structure may include a base unit, in this example a base 700 and a bracket 800. The base 700 may be configured to support the first panel 500, for example to bear at least a portion of the weight of the first panel 500 and the first conveyor unit. A lower end of the base 700 may be placed on and/or attached to a building structure, such as a floor of a conveyor installation site.

The bracket 800 may be provided at an upper portion (e.g., a top end or surface) of the base 700 . The bracket 800 may be pivotally coupled to the base 700 . One end thereof (e.g., a distal portion or end) may support the first plate 500 . The retaining bracket 800 and the base 700 can be connected to one another in an articulated manner by a pivot pin 810, for example, in such a way that the retaining bracket 800 can be folded out of the base 700 and folded back into the base 700 or retracted.

The base 700 and the bracket 800 may function to stably support the first panel 500 and the second panel 600 provided over the first panel 500 (e.g., over one or more gap blocks 910). The base 700 and the bracket 800 can function such that the conveyor is arranged horizontally (e.g. such that the first plate and the second plate 500, 600 are at the same height).

When the conveyor occludes the battery pack (e.g., in the operational configuration), the retaining bracket 800 may support the first panel 500 . In order to replace the belt 420 provided on the first drive shaft 210 mounted on the first plate 500, the bracket 8000 and the first plate 500 may need to be separated for belt 420 replacement. This is because the retaining bracket 800 may become an obstacle when assembling the belt 420 to the first drive shaft 210 or removing the belt 420 from the first drive shaft 210 .

Accordingly, there is a need for a structure in which the retaining bracket 800 and the first panel 500 can be easily separated, such as when the strap 420 is replaced. Thus, in the conveyor device according to an example of the present disclosure, the support bracket 800 may have a distal portion (e.g., an upper end remote from or disposed opposite to the pivot pin 810) provided to support the first plate 500, for example a lower surface of the first panel 500. The retaining bracket 800 can be provided such that it is separated or spaced from the first panel 500 by being folded or retracted (e.g. pivoted/rotated) relative to the base 700 by an external force.

An upper surface (for example, a distal end surface) of the bracket 800 can support the lower surface of the first plate 500 . A separate coupling tool for coupling the bracket 800 and the first panel 500 may not need to be provided. By applying an external force to swing/rotate the bracket 800 relative to the base 700, an operator can easily separate the bracket 800 and the first plate 500.

By appropriately adjusting a fastening strength of the pivot pin 810 such that the bracket 800 is not pivoted/rotated by a relatively weak external force, it is possible to prevent occurrence of an accident in which the bracket 800 is rotated by an external impact in the closing operation and separated from the first plate 500. For example, by adjusting the attachment strength of the pivot pin 810, a threshold force for pivoting/rotating the retaining bracket 800 can be adjusted.

After the strap 420 has been replaced, the user can unfold the bracket 800 relative to the base 700 by again applying an external force (e.g. pivoting/rotating) so that the upper end of the bracket 800 supports the lower surface of the first plate 500.

In the example, the bracket 800 and the first board 500 can be provided in such a manner that they come into contact with each other without a separate coupling mechanism, and even in this structure, the bracket 800 can support the first board 500 .

After replacing the strap 420, the user can pivot/rotate the bracket 800 relative to the base 700 by simply applying an external force and bring the bracket 800 into contact with the first panel 500 or the bracket 800 and the first panel 500 apart separate (e.g. folding and unfolding the retaining bracket 800 in and out of the base 700).

Consequently, since there is no need to disassemble and then reassemble the coupling mechanism designed to couple the bracket 800 and the first plate 500 when replacing the belt 420, it is possible to improve the efficiency of the replacement operation for the belt Belt 420 to improve.
