Description

Technical Field

[0001] This application claims priority based on Korean Patent Application No. 10-2022-0185679 filed on December 27, 2022, and all of the content disclosed in the specification and drawings of the said application is incorporated into this 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 capable of safely transporting produced batteries.

Background Art

[0003] In recent years, the demand for portable electronic products such as notebook computers, video cameras, mobile phones, etc. has grown rapidly, and as the development of electric vehicles, energy storage batteries, robots, satellites, etc. has become full-scale, efforts have been actively made in research on 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, lithium batteries, etc. Among them, lithium batteries are in the spotlight for their advantages of being able to be freely charged and discharged because they hardly have a memory effect compared to nickel-based batteries, having a very low self-discharge rate, and having a high energy density.

[0005] After such batteries are produced, they are stored in a battery tray, and the battery tray is moved by a transport device such as a conveyor. If an impact is applied to the battery tray during the transport process of such batteries, there is a possibility that defects such as cracks may occur in the produced batteries. For example, impacts between battery trays or impacts between a stopper device provided on the conveyor and the battery tray may occur.

[0006] Therefore, there is a need to develop technology that can safely transport batteries by reducing the impact that occurs during the transportation process after production. [Overview of the Initiative] [Problems that the invention aims to solve]

[0029] Furthermore, when a part of the specification is described as being "connected" to another part, this includes not only cases where the parts are "directly connected," but also cases where they are "indirectly connected" with other elements in between.

[0030] In the following, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

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

[0032] Referring to Figure 1, the battery tray 100 may include a housing 110, a storage section 120, a magnetic section 130, a measuring section 140, and a communication section 150. Specifically, the battery tray 100 can transport the mounted battery along a predetermined direction of movement.

[0033] Here, a battery refers to a single, independent cell that has a negative terminal and a positive terminal and is physically separable. For example, a lithium-ion battery or a lithium-polymer battery can be considered a battery. For the sake of explanation, in the following, a battery will be described as 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 a housing section 120, a magnetic section 130, a measuring section 140, and a communication section 150.

[0035] The housing section 120 is located inside the housing 110 and may be configured to accommodate battery cells.

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

[0037] For example, in the embodiment shown in Figure 2, the housing 120 may be provided inside the housing 110, perpendicular to the lower plate of the housing 110. Each of the multiple slots included in the housing 120 may include grooves facing each other. Thus, a manufactured battery can be inserted and secured into each of the multiple slots.

[0038] The magnetic part 130 may be configured to be attached to the outer surface of the housing 110 in one or more places.

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

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

[0041] In the embodiment shown in Figure 2, 16 magnetic parts 130 can be attached to the outer surface of the housing 110. The 16 magnetic parts 130 can have a north pole facing outwards from the housing 110 and a south pole facing inwards from the housing 110. That is, when two or more battery trays 100 are brought close to each other, a repulsive force can act between the battery trays 100.

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

[0043] Specifically, the measuring unit 140 can measure various transport information that can be measured while the battery tray 100 is being transported. Preferably, the measuring 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 measuring unit 140 may include acceleration information and angular velocity information of the battery tray 100.

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

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

[0046] A battery tray 100 according to one embodiment of the present invention may further include a magnetic part 130 for reducing the impact applied to the battery tray 100. Therefore, the impact applied to the battery mounted on the battery tray 100 is mitigated, preventing problems such as cracks from occurring in the battery during transport.

[0047] Figure 3 is a schematic diagram showing a battery transport system 10 according to another embodiment of the present invention.

[0048] Referring to Figure 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 is the same as the battery tray 100 described earlier, and therefore its explanation is omitted here.

[0050] The transport device 200 may be configured to transport the battery tray 100 along a predetermined transport direction.

[0051] Specifically, the transport device 200 may be pre-configured to transport the battery tray 100 in a predetermined transport direction. That is, the battery tray 100 may be introduced from one end of the transport device 200, transported along the predetermined transport direction, and output from the other end of the transport device 200.

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

[0053] The communication device 300 can be connected to the communication unit 150 in a communication manner.

[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 in a way that enables bidirectional communication.

[0055] The communication device 300 may 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, having transmitted the first signal, may transmit a second signal to the communication device 300. The communication device 300 may calculate the distance to the battery tray 100 using the communication time from the time the first signal was transmitted to the time the second signal was 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 multiple communication devices 300. For example, each of the multiple communication devices 300 can calculate the distance to the battery tray 100. Each of the multiple communication devices 300 can then transmit distance information regarding 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 in 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 in 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 distance information received.

[0060] For example, suppose the battery transport 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 three pieces of distance information it has received.

[0061] Figures 4 to 7 schematically illustrate exemplary configurations of a battery transport system 10 according to other embodiments of the present invention. Specifically, the embodiment in Figure 4 schematically shows a transport device 200, a communication device 300, and a control device 400. The embodiment in Figure 5 further illustrates the stopper device 500 in the embodiment in Figure 4. The embodiment in Figure 6 further illustrates the magnetic device 600 in the embodiment in Figure 5. The embodiment in Figure 7 further illustrates the battery tray 100 in the embodiment in Figure 6.

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

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

[0064] Specifically, the stopper device 500 can be fixedly coupled to the transport device 200 at points where the direction of movement of the battery tray 100 by the transport device 200 is changed. For example, when the direction of movement of the battery tray 100 is changed, the battery tray 100 may detach from the transport device 200. Therefore, in order to prevent the battery tray 100 from detaching, the stopper device 500 can be fixedly coupled to the transport device 200 at points where the direction of movement of the transport device 200 is changed.

[0065] For example, in the embodiment shown in Figure 4, the direction of movement may start in the +x direction, change to the -y direction, and then change back to the +x direction. That is, the direction of movement may change in areas z1 and z2.

[0066] In area 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 area 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, in order to prevent the battery tray 100 from detaching, a stopper device 500 may be provided at the location where the direction of movement is changed, as shown in the embodiment of Figure 5.

[0067] In the embodiment shown in Figure 5, the first stopper device 500a can prevent the battery tray 100 from detaching in the +x direction. The second stopper device 500b can prevent the battery tray 100 from detaching in the -y direction.

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

[0069] In the embodiment shown in Figure 5, if the battery tray 100, which is being transported along the direction of movement, collides with the first stopper device 500a or the second stopper device 500b, the battery tray 100 and the battery may be subjected to impact. That is, although the battery tray 100 can be prevented from detaching, the battery may be subjected to impact, which could lead to defects 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, a magnetic device 600 may be attached to the outer surface of the stopper device 500 so as to correspond to the direction of movement of the battery tray 100. In the embodiment shown in Figure 6, a first magnetic device 600a may be attached to the outer surface of the first stopper device 500a. A 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 such that the polarity toward the battery tray 100 is the same as the polarity of the magnetic part 130 toward the outside of the housing 110. For example, when the battery tray 100 is brought close to the magnetic device 600, a repulsive force may act between the magnetic part 130 of the battery tray 100 and the magnetic device 600. Such a repulsive force can reduce the impact between the battery tray 100 and the magnetic device 600.

[0072] In the embodiment shown in Figure 6, it is assumed that the polarity of the magnetic part 130 facing outward from the housing 110 is north (N). In the first magnetic device 600a, the polarity facing the -x direction may be north (N). In the second magnetic device 600b, the polarity facing the +y direction may be north (N).

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

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

[0075] The battery transport system 10 has the advantage of effectively reducing the impact applied to the battery tray 100 while guiding the direction of movement of the battery tray 100 so that it does not detach from the transport device 200. Therefore, the rate of battery failure due to impact during the battery transport process by the battery tray 100 can be significantly reduced.

[0076] The following describes an embodiment in which the control device 400 controls the operating state of the magnetic device 600, using the embodiment shown in Figure 7.

[0077] In the embodiment shown in Figure 7, the first communication device 300a, the second communication device 300b, and the third communication device 300c can be connected to the communication unit 150 of the battery tray 100 in a communicative manner. Each of the first communication device 300a, the second communication device 300b, and the third communication device 300c can calculate the 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 can determine the position of the battery tray 100 in the transport device 200 based on R1, R2, and R3. Specifically, the control device 400 can 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 operating state of the magnetic device 600 so that the magnetic device 600 becomes magnetic if the distance between the battery tray 100 and the stopper device 500 is less than or equal to a preset reference distance. Preferably, the control device 400 can control the operating state of the magnetic device 600 so that the magnetic device 600 becomes magnetic when the distance between the battery tray 100 and the stopper device 500 reaches a preset reference distance.

[0081] In the following explanation, we will assume 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 installed.

[0083] For example, in the embodiment shown in Figure 7, the control device 400 can calculate the distance between the position of the battery tray 100 and the first stopper device 500a as R4. Preferably, since 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 can calculate the distance between the battery tray 100 and the stopper device 500 that is closest to the direction in which the battery tray 100 is facing.

[0084] The control device 400 can then 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 can 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 can be preset based on a preset unit transport distance for the transport device 200 (for example, transport distance per second) and the time from the point in time when the operation of the magnetic device 600 is changed until the point in time when the maximum magnetic force is generated.

[0085] For example, in the embodiment shown in Figure 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 that current flows through the magnetic device 600 and the magnetic device 600 becomes magnetized in accordance with the flow of current. The turn-off state means that no current flows through the magnetic device 600 and the magnetic device 600 does not become magnetized.

[0087] Here, the direction of the current when the device is turned on can 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 north pole, and the polarity of the magnetic part 130 facing the inside of the housing 110 is south pole. The direction of the current when the device is turned on can be preset so that the polarity of the magnetic device 600 facing the battery tray 100 is north pole, and the polarity of the magnetic device 600 facing the stopper device 500 is south pole.

[0088] If the magnetic device 600 remains in the turned-on state even though the battery tray 100 has not 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 the turned-on state if the distance between the battery tray 100 and the stopper device 500 is less than or equal to a reference distance.

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

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

[0092] The communication device 300 can then transmit impact amount information related to the calculated impact amount to the control device 400.

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

[0094] Specifically, the critical impact amount can be pre-set to an impact amount sufficient to cause defects in the battery. For example, if the impact amount exceeds the critical impact amount, cracks or other damage may occur in the battery.

[0095] If the calculated impact amount is greater than or equal to the critical impact amount, the control device 400 may change the communication cycle and measurement cycle to more accurately detect the position of the battery tray 100. Preferably, the control device 400 may change the communication cycle to shorten the communication cycle between the communication unit 150 and the communication device 300, and change the measurement cycle to shorten the measurement cycle of the measurement unit 140. That is, in accordance with the shortened measurement cycle, transport information about the battery tray 100 can be measured more frequently, and in accordance with the shortened communication cycle, the transport information can be transmitted to the communication device 300 more quickly than before. Since 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 in the transport device 200 at a shorter cycle than before.

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

[0097] Referring to Figure 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 to light up 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 a critical impact amount, the control device 400 may change the communication strength of the communication unit 150 to equal or greater than the critical strength. That is, the communication unit 150 may output a signal with an strength equal to or greater than the critical strength. Therefore, by checking the alarm device 700, the user or operator can easily confirm whether or not there are any defects in the battery tray 100 being transported by the transport device 200.

[0099] Although the present invention has been described above with reference to limited embodiments and drawings, it goes without saying that the present invention is not limited thereto, and that various modifications and variations are possible within the equivalent scope of the technical idea of ​​the present invention and the appended claims by persons with ordinary skill in the art to which the present invention pertains.

[0100] Furthermore, the present invention described above can be modified and altered in various ways by a person with ordinary skill in the art to which the present invention belongs, without departing from the technical spirit of the invention.
