Description

[Technical Field]

[0001] This application claims priority based on Korean Patent Application No. 10-2022-0185679, filed on December 27, 2022, the entire contents of which are incorporated herein by reference in their entirety in the specification and drawings of that application.

[0002] The present invention relates to a battery tray and a battery transport system, and more particularly to a battery tray and a battery transport system that can safely transport manufactured batteries. [Background technology]

[0003] In recent years, the demand for portable electronic products such as laptops, video cameras, and mobile phones has grown rapidly, and as the development of electric vehicles, energy storage batteries, robots, satellites, and other products has gained momentum, there has been active research into high-performance batteries that can be repeatedly charged and discharged.

[0004] Currently, commercially available batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium batteries. Among these, lithium batteries are attracting attention due to their advantages of being able to be freely charged and discharged since they have almost no memory effect compared to nickel-based batteries, as well as their extremely low self-discharge rate and high energy density.

[0005] After being produced, these batteries are housed in battery trays, which are then moved by a transport device such as a conveyor. If the battery trays are subjected to impact during the battery transport process, defects such as cracks may occur in the produced batteries. For example, impacts may occur between battery trays or between the battery trays and a stopper device installed on the conveyor.

[0006] Therefore, there is a need to develop technology that can safely transport batteries by reducing the impact that occurs during the transportation process of produced batteries. Summary of the Invention [Problem to be solved by the invention]

[0030] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] Figure 1 is a diagram illustrating a battery tray 100 according to one embodiment of the present invention. Figure 2 is a diagram illustrating an exemplary configuration of the battery tray 100 according to one embodiment of the present invention.

[0032] 1, the battery tray 100 may include a housing 110, a storage portion 120, a magnetic portion 130, a measuring portion 140, and a communication portion 150. Specifically, the battery tray 100 can transport the mounted battery along a predetermined moving direction.

[0033] Here, a battery refers to a single independent cell that has a negative terminal and a positive terminal and can be physically separated. As an example, a lithium ion battery or a lithium polymer battery can be considered a battery. For convenience of explanation, the following description will be made assuming that a battery refers to a single independent cell.

[0034] The housing 110 may be configured to accommodate other components of the battery tray 100. For example, the housing 110 may be provided with the accommodating portion 120, the magnetic portion 130, the measuring portion 140, and the communication portion 150.

[0035] The receiving portion 120 may be provided inside the housing 110 and configured to receive the battery cell.

[0036] Specifically, the receiving portion 120 may include a plurality of slots with opposing grooves, and one battery may be inserted into each slot.

[0037] 2, the receiving portion 120 may be disposed inside the housing 110 in a direction perpendicular to the bottom plate of the housing 110. The plurality of slots included in the receiving portion 120 may include grooves facing each other. Thus, a manufactured battery may be inserted and fixed into each of the plurality of slots.

[0038] The magnetic portion 130 may be configured to be attached to one or more outer surfaces of the housing 110 .

[0039] Specifically, the magnetic unit 130 may be configured to include a magnetic material. The magnetic unit 130 may have a first polarity facing the outside of the housing 110 and a second polarity facing the inside of the housing 110. For example, the magnetic unit 130 may have a north pole facing the outside of the housing 110 and a south pole facing the inside of the housing 110.

[0040] Preferably, when multiple magnetic portions 130 are attached to the outer surface of the housing 110, the magnetic portions 130 may be configured to have the same polarity facing the outside of the housing 110. For example, the multiple magnetic portions 130 may have a north pole facing the outside of the housing 110 and a south pole facing the inside of the housing 110.

[0041] 2, 16 magnetic portions 130 may be attached to the outer surface of the housing 110. The 16 magnetic portions 130 may have a north pole facing the outside of the housing 110 and a south pole facing the inside of the housing 110. That is, when two or more battery trays 100 are brought close to each other, a repulsive force may act between the battery trays 100.

[0042] The measuring unit 140 may be configured to measure the transportation information of the battery tray 100 .

[0043] Specifically, the measurement unit 140 may measure various pieces of transport information that can be measured while the battery tray 100 is being transported. Preferably, the measurement unit 140 may be configured to measure at least one of the acceleration and angular velocity of the battery tray 100. For example, the transport information of the battery tray 100 measured by the measurement unit 140 may include acceleration information and angular velocity information of the battery tray 100.

[0044] The communication unit 150 can be configured to output the transportation information measured by the measurement unit 140 to the outside.

[0045] For example, the communication unit 150 may be attached to the battery tray 100 being transported. Therefore, the communication unit 150 may output the carrier information to the outside via wireless communication. Preferably, the communication unit 150 may output the carrier information to the outside using ultra wide band (UWB) technology.

[0046] The battery tray 100 according to an embodiment of the present invention may further include a magnetic portion 130 for reducing impacts applied to the battery tray 100. Therefore, impacts applied to the batteries mounted on the battery tray 100 are reduced, thereby preventing problems such as cracks from occurring in the batteries during transportation.

[0047] FIG. 3 is a diagram schematically illustrating a battery transport system 10 according to another embodiment of the present invention.

[0048] Referring to FIG. 3 , the battery transport system 10 may include a battery tray 100, a transport device 200, a communication device 300, and a control device 400.

[0049] The battery tray 100 included in the battery transport system 10 corresponds to the battery tray 100 described above, and a description thereof will be omitted here.

[0050] The conveying device 200 may be configured to convey the battery tray 100 along a preset conveying direction.

[0051] Specifically, the conveying device 200 may be pre-installed so as to be able to convey the battery trays 100 in a pre-set conveying direction. That is, the battery trays 100 may be introduced into one end of the conveying device 200, conveyed along the pre-set conveying direction, and then output from the other end of the conveying device 200.

[0052] For example, the transport device 200 may be a conveyor capable of transporting the battery trays 100. After being introduced into the transport device 200, the battery trays 100 may move along a transport direction set by the transport device 200.

[0053] The communication device 300 can be communicatively connected to the communication unit 150 .

[0054] For example, the communication device 300 may be connected to the communication unit 150 via wireless communication. Preferably, the communication device 300 may be connected to the communication unit 150 so as to be capable of two-way communication.

[0055] The communication device 300 can be configured to calculate the distance to the battery tray 100 using the communication time with the communication unit 150.

[0056] For example, the communication device 300 may transmit a first signal to the communication unit 150 of the battery tray 100. The communication unit 150 that transmitted the first signal may then transmit a second signal to the communication device 300. The communication device 300 may calculate the distance to the battery tray 100 by using the communication time from the time the first signal is transmitted to the time the second signal is received. The communication device 300 may calculate the distance to the battery tray 100 by multiplying the speeds of the first and second signals by the communication time.

[0057] Preferably, there may be a plurality of communication devices 300. For example, each of the plurality of communication devices 300 may calculate the distance to the battery tray 100. Then, each of the plurality of communication devices 300 may transmit distance information relating to the calculated distance to the control device 400.

[0058] The control device 400 may be configured to determine the position of the battery tray 100 on the transport device 200 based on the distance calculated by the communication device 300.

[0059] Specifically, the control device 400 can determine the position of the battery tray 100 on the transport device 200. Preferably, the control device 400 can receive distance information from a plurality of communication devices 300. Then, the control device 400 can determine the position of the battery tray 100 based on the plurality of pieces of distance information received.

[0060] For example, assume that the battery transportation system 10 includes three communication devices 300. The control device 400 can receive three pieces of distance information from the three communication devices 300. The control device 400 can then determine the position of the battery tray 100 by comprehensively considering the received three pieces of distance information.

[0061] 4 to 7 are schematic diagrams illustrating exemplary configurations of a battery transport system 10 according to other embodiments of the present invention. Specifically, the embodiment of FIG. 4 is a schematic diagram illustrating a transport device 200, a communication device 300, and a control device 400. The embodiment of FIG. 5 is a diagram further illustrating a stopper device 500 in the embodiment of FIG. 4. The embodiment of FIG. 6 is a diagram further illustrating a magnetic device 600 in the embodiment of FIG. 5. The embodiment of FIG. 7 is a diagram further illustrating a battery tray 100 in the embodiment of FIG. 6.

[0062] Referring to FIG. 3 , the battery transport system 10 may further include a stopper device 500 and a magnetic device 600 .

[0063] The stopper device 500 may be fixedly coupled to the transport device 200 to stop the transport of the battery tray 100.

[0064] Specifically, the stopper device 500 may be fixedly coupled to the conveying device 200 at a location where the direction of movement of the battery tray 100 by the conveying device 200 changes. For example, when the direction of movement of the battery tray 100 changes, the battery tray 100 may become detached from the conveying device 200. Therefore, to prevent the battery tray 100 from becoming detached, the stopper device 500 may be fixedly coupled to the location where the direction of movement of the conveying device 200 changes.

[0065] For example, in the embodiment of Figure 4, the movement direction may start in the +x direction, change to the -y direction, and then change back to the +x direction, i.e., the movement direction may be changed in zone z1 and zone z2.

[0066] In zone z1, if the battery tray 100 continues to move in the +x direction, there is a possibility that the battery tray 100 will detach from the transport device 200. Similarly, in zone z2, if the battery tray 100 continues to move in the -y direction, there is a possibility that the battery tray 100 will detach from the transport device 200. Therefore, to prevent the battery tray 100 from detaching, a stopper device 500 may be provided at the point where the direction of movement changes, as shown in the embodiment of FIG. 5 .

[0067] 5, the first stopper device 500a can prevent the battery tray 100 from being separated in the +x direction, and the second stopper device 500b can prevent the battery tray 100 from being separated in the -y direction.

[0068] The magnetic device 600 is attached to the outer surface of the stopper device 500 and can be configured to become magnetic depending on the operating state.

[0069] 5, if the battery tray 100 being transported in the movement direction collides with the first stopper device 500a or the second stopper device 500b, an impact may be applied to the battery tray 100 and the battery. That is, although separation of the battery tray 100 can be prevented, the battery may be subjected to an impact, which may result in a defect in the battery. Therefore, a magnetic device 600 may be attached to the stopper device 500 to mitigate the impact applied to the battery tray 100.

[0070] Specifically, the magnetic devices 600 may be attached to the outer surface of the stopper device 500 to correspond to the movement direction of the battery tray 100. In the embodiment of Fig. 6, the first magnetic device 600a may be attached to the outer surface of the first stopper device 500a, and the second magnetic device 600b may be attached to the outer surface of the second stopper device 500b.

[0071] Preferably, the magnetic device 600 may be configured so that the polarity facing the battery tray 100 is the same as the polarity of the magnetic portion 130 facing the outside of the housing 110. For example, when the battery tray 100 is brought close to the magnetic magnetic device 600, a repulsive force may act between the magnetic portion 130 of the battery tray 100 and the magnetic device 600. This repulsive force can reduce impact between the battery tray 100 and the magnetic device 600.

[0072] 6, it is assumed that the polarity of the magnetic portion 130 facing the outside of the housing 110 is the north pole. In the first magnetic device 600a, the polarity facing the -x direction may be the north pole. In the second magnetic device 600b, the polarity facing the +y direction may be the north pole.

[0073] For example, when the battery tray 100 moves in the +x direction and approaches the first stopper device 500a, the first magnetic portion 130a and the second magnetic portion 130b may approach the first magnetic device 600a. In this case, a repulsive force may act between the first magnetic portion 130a and the first magnetic device 600a, and between the second magnetic portion 130b and the first magnetic device 600a. Therefore, the amount of impact on the battery tray 100 and the first magnetic device 600a may be reduced.

[0074] In another example, when the battery tray 100 moves in the -y direction and approaches the second stopper device 500b, the third magnetic portion 130c and the fourth magnetic portion 130d may approach the second magnetic device 600b. In this case, repulsive forces may act between the third magnetic portion 130c and the second magnetic device 600b, and between the fourth magnetic portion 130d and the second magnetic device 600b. Therefore, the amount of impact on the battery tray 100 and the second magnetic device 600b may be reduced.

[0075] The battery transportation system 10 has the advantage of effectively reducing impacts on the battery trays 100 while guiding the movement direction of the battery trays 100 so that the battery trays 100 do not detach from the transportation device 200. Therefore, the rate of battery defects caused by impacts during the battery transportation process using the battery trays 100 can be significantly reduced.

[0076] Hereinafter, an embodiment in which the control device 400 controls the operating state of the magnetic device 600 will be described using the embodiment of FIG.

[0077] 7, the first communication device 300a, the second communication device 300b, and the third communication device 300c may be communicatively connected to the communication unit 150 of the battery tray 100. Each of the first communication device 300a, the second communication device 300b, and the third communication device 300c may calculate a distance to the battery tray 100. The distance between the first communication device 300a and the battery tray 100 may be R1, the distance between the second communication device 300b and the battery tray 100 may be R2, and the distance between the third communication device 300c and the battery tray 100 may be R3.

[0078] The control device 400 may determine the position of the battery tray 100 on the transport device 200 based on R1, R2, and R3. Specifically, the control device 400 may determine the position of the battery tray 100 based on trilateration using the position of the first communication device 300a and R1, the position of the second communication device 300b and R2, and the position of the third communication device 300c and R3.

[0079] The control device 400 may be configured to control the operating state of the magnetic device 600 based on the position of the battery tray 100 and the position of the stopper device 500 .

[0080] Specifically, the control device 400 may be configured to control the operation state of the magnetic device 600 so that the magnetic device 600 becomes magnetic when the distance between the position of the battery tray 100 and the position of the stopper device 500 is equal to or less than a preset reference distance. Preferably, the control device 400 may control the operation state of the magnetic device 600 so that the magnetic device 600 becomes magnetic when the distance between the position of the battery tray 100 and the position of the stopper device 500 reaches a preset reference distance.

[0081] In the following description, it is assumed that the position of the stopper device 500 and the position of the magnetic device 600 are substantially the same, since the magnetic device 600 is attached to the outer surface of the stopper device 500.

[0082] Specifically, the control device 400 can calculate the distance between the determined position of the battery tray 100 and the position where the stopper device 500 is provided.

[0083] 7, the control device 400 may calculate the distance between the position of the battery tray 100 and the first stopper device 500a as R4. Preferably, because the battery tray 100 is moving in the +x direction toward the first stopper device 500a, the distance between the battery tray 100 and the second stopper device 500b may not be calculated. That is, the control device 400 may calculate the distance between the battery tray 100 and the stopper device 500 at a position closest to the direction in which the battery tray 100 is facing.

[0084] Then, the control device 400 may compare the calculated distance (the distance between the battery tray 100 and the stopper device 500) with a preset reference distance. Here, the reference distance may be preset as the minimum distance at which the magnetic force of the magnetic device 600 is maximized before the battery tray 100 reaches the magnetic device 600 when the control device 400 controls the operation of the magnetic device 600. That is, the reference distance may be preset based on a unit conveying distance (e.g., conveying distance per second) preset for the conveying device 200 and the time from when the operation of the magnetic device 600 is changed to when the maximum magnetic force is generated.

[0085] For example, in the embodiment of FIG. 7, when R4 reaches a preset reference distance, the control device 400 may change the operating state of the first magnetic device 600a so that the first magnetic device 600a becomes magnetic.

[0086] The control device 400 can control the operating state of the magnetic device 600 to a turn-on state or a turn-off state. The turn-on state means a state in which a current flows through the magnetic device 600 and the magnetic device 600 becomes magnetic in response to the current flow. The turn-off state means a state in which no current flows through the magnetic device 600 and the magnetic device 600 does not become magnetic.

[0087] Here, the direction of current in the turn-on state may be preset so that the polarity of the magnetic device 600 facing the battery tray 100 is the same as the polarity of the magnetic part 130 facing the outside of the housing 110. For example, assume that the polarity of the magnetic part 130 facing the outside of the housing 110 is a north pole and the polarity of the magnetic part 130 facing the inside of the housing 110 is a south pole. The direction of current in the turn-on state may be preset so that the polarity of the magnetic device 600 facing the battery tray 100 is a north pole and the polarity of the magnetic device 600 facing the stopper device 500 is a south pole.

[0088] If the magnetic device 600 is maintained in a turned-on state even though the battery tray 100 has not yet reached the stopper device 500, unnecessary energy will be consumed. Therefore, the control device 400 can control the operating state of the magnetic device 600 to a turned-on state if the distance between the battery tray 100 and the stopper device 500 is less than a reference distance.

[0089] The battery transport system 10 can prevent unnecessary resource consumption and reduce the amount of impact applied to the battery trays 100. Therefore, batteries can be transported safely and efficiently.

[0090] The communication device 300 can be configured to receive the transportation information from the communication unit 150 and calculate the amount of impact applied to the battery tray 100 based on the received transportation information.

[0091] Specifically, the communication device 300 can calculate the amount of impact applied to the battery tray 100 based on at least one of the acceleration information and the angular velocity information received from the communication unit 150. Preferably, the communication device 300 can calculate the amount of impact applied to the battery tray 100 based on the acceleration information and the angular velocity information.

[0092] Then, the communication device 300 can transmit impact amount information regarding the calculated impact amount to the control device 400.

[0093] The control device 400 can be configured to change the communication period between the communication unit 150 and the communication device 300 and the measurement period of the measurement unit 140 if the amount of impact calculated by the communication device 300 is equal to or greater than a predetermined critical impact amount.

[0094] Specifically, the critical impact amount may be preset to a level that will cause a defect in the battery. For example, if the impact amount is greater than or equal to the critical impact amount, the battery may crack.

[0095] If the calculated impact amount is equal to or greater than the critical impact amount, the control device 400 may change the communication period and the measurement period to more accurately detect the position of the battery tray 100. Preferably, the control device 400 may change the communication period between the communication unit 150 and the communication device 300 to shorten the communication period, and may change the measurement period of the measurement unit 140 to shorten the measurement period. That is, the shorter measurement period allows the control device 400 to measure transportation information about the battery tray 100 more frequently and transmit the transportation information to the communication device 300 more quickly than before. Because the control device 400 can receive distance information from the communication device 300 to the battery tray 100 more quickly than before, the control device 400 can determine the position of the battery tray 100 on the transportation device 200 in a shorter period than before.

[0096] Furthermore, the control device 400 can be configured to further change the communication strength of the communication unit 150 if the calculated impact amount is equal to or greater than the critical impact amount.

[0097] Referring to FIG. 3, the battery transport system 10 may further include an alarm device 700.

[0098] The alarm device 700 may be configured to receive a signal output from the communication unit 150 and illuminate or flash if the strength of the received signal is equal to or greater than a preset critical strength. Specifically, if the calculated impact amount is equal to or greater than the critical impact amount, the control device 400 may change the communication strength of the communication unit 150 to equal to or greater than the critical strength. That is, a signal having an intensity equal to or greater than the critical strength may be output from the communication unit 150. Therefore, by checking the alarm device 700, a user or worker can easily check whether or not there is a defect in the battery tray 100 being transported by the transport device 200.

[0099] Although the present invention has been described above using limited embodiments and drawings, the present invention is not limited thereto, and it goes without saying that various modifications and variations can be made by a person having ordinary knowledge in the technical field to which the present invention pertains within the technical spirit of the present invention and the equivalent scope of the appended claims.

[0100] Furthermore, the present invention described above is susceptible to various substitutions, modifications, and alterations by a person having ordinary knowledge in the technical field to which the present invention pertains, within the scope of the technical concept of the present invention.
