Description

Technical Field

[0001] This application claims priority to Korean Patent Application No. 10-2022-0185679 filed in Korea on December 27, 2022, the disclosure of which is incorporated herein by reference.

[0002] The present invention relates to a battery tray and a battery conveying system, and more particularly, to a battery tray and a battery conveying system which can safely convey produced batteries. Background Art

[0003] Recently, the demand for portable electronic products such as laptop computers, video cameras, and portable phones has increased dramatically, and electric vehicles, energy storage batteries, robots, satellites, etc. have been developed in earnest. Therefore, high-performance batteries that allow repeated charging and discharging are being actively researched.

[0004] Currently commercially available batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, lithium batteries, etc. Among them, lithium batteries have attracted much attention because compared with nickel-based batteries, lithium batteries have almost no memory effect, and also have very low self-charging rate and high energy density.

[0005] After these batteries are produced, they are placed in a battery tray, and the battery tray may be moved through a transfer device such as a conveyor. If vibration is applied to the battery tray during the battery transfer process, the produced batteries may have problems such as cracks. For example, vibration may occur between battery trays, and vibration may also occur between a stopper provided on the conveyor and the battery tray.

[0006] Therefore, it is necessary to develop a technology that can safely transfer batteries by reducing vibration generated during the transfer process of produced batteries. Summary of the invention

[0036] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0037] Figure 1 is a diagram schematically illustrating a battery tray 100 according to an embodiment of the present disclosure. Figure 2 is a diagram schematically illustrating an exemplary configuration of a battery tray 100 according to an embodiment of the present disclosure.

[0038] Reference Figure 1 , the battery tray 100 may include a housing 110, a receiving portion 120, a magnetic unit 130, a measuring unit 140, and a communication unit 150. Specifically, the battery tray 100 may transfer the loaded batteries along a designated moving direction.

[0039] Here, a battery refers to an individual cell having a negative electrode terminal and a positive electrode terminal and being physically separable. For example, a lithium-ion cell or a lithium polymer cell may be considered a battery. Hereinafter, for ease of explanation, a battery is interpreted as meaning an individual cell.

[0040] The housing 110 may be configured such that other components of the battery tray 100 may be installed therein. For example, the receiving portion 120 , the magnetic unit 130 , the measuring unit 140 , and the communication unit 150 may be installed in the housing 110 .

[0041] The receiving portion 120 is installed inside the housing 110 and may be configured to allow a battery cell to be inserted.

[0042] Specifically, the receiving portion 120 may include a plurality of slots having opposite grooves. In addition, a battery may be inserted into each slot.

[0043] For example, in Figure 2In the embodiment of the present invention, the receiving portion 120 may be installed inside the housing 110 in a vertical direction on the lower plate of the housing 110. In addition, each of the plurality of slots included in the receiving portion 120 may include grooves facing each other. Therefore, the produced battery can be inserted and fixed in each of the plurality of slots.

[0044] The magnetic units 130 may be configured such that at least one magnetic unit 130 is attached to the outer surface of the housing 110 .

[0045] Specifically, the magnetic unit 130 may be configured to include a magnetic body. In addition, the magnetic unit 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 unit 130 may have an N pole toward the outside of the housing 110 and an S pole toward the inside of the housing 110.

[0046] Preferably, when a plurality of magnetic units 130 are attached to the outer surface of the housing 110, the magnetic units 130 may be configured so that the magnetic units 130 facing the outside of the housing 110 have the same polarity. For example, the plurality of magnetic units 130 may have an N pole facing the outside of the housing 110 and an S pole facing the inside of the housing 110.

[0047] exist Figure 2 In an embodiment, 16 magnetic units 130 may be attached to the outer surface of the housing 110. In addition, the 16 magnetic units 130 may have N poles facing the outside of the housing 110 and S poles facing the inside of the housing 110. In other words, when two or more battery trays 100 are close, a repulsive force may act between the battery trays 100.

[0048] The measuring unit 140 may be configured to measure the transmission information of the battery tray 100 .

[0049] Specifically, the measuring unit 140 may measure various transmission information that may be measured when the battery tray 100 is transmitted. Preferably, the measuring unit 140 may be configured to measure at least one of the acceleration and the angular velocity of the battery tray 100. For example, the transmission information of the battery tray 100 measured by the measuring unit 140 may include the acceleration information and the angular velocity information of the battery tray.

[0050] The communication unit 150 may be configured to output the transmission information measured by the measurement unit 140 to the outside.

[0051] For example, the communication unit 150 may be attached to the transferred battery tray 100. Therefore, the communication unit 150 may output the transfer information to the outside through wireless communication. Preferably, the communication unit 150 may output the transfer information to the outside using ultra-wideband (UWB) wireless technology.

[0052] The battery tray 100 according to an embodiment of the present disclosure may further include a magnetic unit 130 to reduce impact applied to the battery tray 100. Therefore, since impact applied to the batteries loaded on the battery tray 100 is mitigated, problems such as cracks occurring in the batteries during transfer may be prevented.

[0053] Figure 3 is a diagram schematically showing a battery conveying system 10 according to another embodiment of the present disclosure.

[0054] Reference Figure 3 The battery conveying system 10 may include a battery tray 100 , a conveying device 200 , a communication device 300 , and a control device 400 .

[0055] Since the battery tray 100 included in the battery conveying system 10 corresponds to the above-described battery tray 100 , a description thereof is omitted.

[0056] The conveying device 200 may be configured to convey the battery tray 100 along a preset conveying direction.

[0057] Specifically, the conveyor 200 may be pre-installed to convey the battery tray 100 in a preset conveying direction. That is, the battery tray 100 may be introduced at one end of the conveyor 200, the battery tray 100 may be conveyed along the preset conveying direction, and the battery tray 100 may also be output at the other end of the conveyor 200.

[0058] For example, the transfer device 200 may be a conveyor capable of transferring the battery tray 100. After the battery tray 100 is introduced into the transfer device 200, the battery tray 100 may move in a transfer direction set by the transfer device 200.

[0059] The communication device 300 may be connected to communicate with the communication unit 150 .

[0060] For example, the communication device 300 may be connected to the communication unit 150 through wireless communication. Preferably, the communication device 300 may be connected to the communication unit 150 to achieve two-way communication.

[0061] 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 .

[0062] 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 point of transmitting the first signal to the time point of receiving the second signal. The communication device 300 may calculate the distance to the battery tray 100 by multiplying the speeds of the first signal and the second signal by the communication time.

[0063] Preferably, a plurality of communication devices 300 may be provided. For example, each of the plurality of communication devices 300 may calculate the distance to the battery tray 100. Furthermore, each of the plurality of communication devices 300 may transmit distance information related to the calculated distance to the control device 400.

[0064] The control device 400 may be configured to determine the position of the battery tray 100 in the conveying device 200 based on the distance calculated by the communication device 300 .

[0065] Specifically, the control device 400 may determine the position of the battery tray 100 in the conveying device 200. Preferably, the control device 400 may receive distance information from a plurality of communication devices 300. In addition, the control device 400 may determine the position of the battery tray 100 based on the received plurality of distance information.

[0066] For example, it is assumed that the battery conveying system 10 includes three communication devices 300. The control device 400 may receive three distance information from the three communication devices 300. In addition, the control device 400 may determine the position of the battery tray 100 by combining the three received distance information.

[0067] Figures 4 to 7 Schematically shows an exemplary configuration of a battery conveying system 10 according to another embodiment of the present disclosure. Specifically, Figure 4 The embodiment of FIG. 1 is a diagram schematically showing a transmission device 200 , a communication device 300 , and a control device 400 . Figure 5 The embodiment is further shown Figure 4 FIG. 5 is a diagram of a stopping device 500 in an embodiment of the present invention. Figure 6 The implementation method is to further illustrate Figure 5 Schematic diagram of a magnetic device 600 in an embodiment. Figure 7 The embodiment is further shown Figure 6 FIG. 1 is a diagram of a battery tray 100 in an embodiment of the present invention.

[0068] Reference Figure 3 The battery conveying system 10 may further include a stopping device 500 and a magnetic device 600 .

[0069] The stopping device 500 may be fixedly coupled to the conveying device 200 to stop the conveyance of the battery tray 100 .

[0070] Specifically, the stopper 500 may be fixedly coupled to the conveyor 200 at a point where the conveyor 200 changes the moving direction of the battery tray 100. For example, when the moving direction of the battery tray 100 is changed, the battery tray 100 may be separated from the conveyor 200. Therefore, in order to prevent the battery tray 100 from being separated, the stopper 500 may be fixedly coupled at a point where the moving direction of the conveyor 200 is changed.

[0071] For example, in Figure 4 In the embodiment of the present invention, the moving direction may start from the +x direction, change to the -y direction, and then change to the +x direction again. That is, the moving direction may change in the z1 interval and the z2 interval.

[0072] If the battery tray 100 continues to move in the +x direction in the z1 section, the battery tray 100 may be separated from the conveying device 200. Similarly, if the battery tray 100 continues to move in the -y direction in the z2 section, the battery tray 100 may be separated from the conveying device 200. Therefore, in order to prevent the battery tray 100 from being separated, a stopper 500 may be installed at a point where the moving direction changes, such as Figure 5 As shown in the implementation method of .

[0073] exist Figure 5 In the embodiment of the present invention, the first stopper 500a can prevent the battery tray 100 from being separated in the +x direction. The second stopper 500b can prevent the battery tray 100 from being separated in the -y direction.

[0074] The magnetic device 600 is attached to the outer surface of the stopping device 500 and may be configured to exhibit magnetism depending on an operation state.

[0075] exist Figure 5 In the embodiment of the present invention, when the battery tray 100 conveyed in the moving direction collides with the first stopper 500a or the second stopper 500b, vibration may be applied to the battery tray 100 and the battery. In other words, the separation of the battery tray 100 can be prevented, but the battery may be subjected to vibration, and thus a battery defect may occur. Therefore, in order to mitigate the impact applied to the battery tray 100, the magnetic device 600 may be attached to the stopper 500.

[0076] Specifically, the magnetic device 600 may be attached to the outer surface of the stopper 500 to correspond to the moving direction of the battery tray 100. Figure 6In the embodiment of the present invention, the first magnetic device 600a can be attached to the outer surface of the first stopper 500a. In addition, the second magnetic device 600b can be attached to the outer surface of the second stopper 500b.

[0077] 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 unit 130 facing the outside of the housing 110. For example, when the battery tray 100 approaches the magnetic device 600 using magnetism, a repulsive force may act between the magnetic unit 130 of the battery tray 100 and the magnetic device 600. The impact between the battery tray 100 and the magnetic device 600 may be reduced by the repulsive force.

[0078] exist Figure 6 In the embodiment of FIG. 1 , it is assumed that the polarity of the magnetic unit 130 facing the outside of the housing 110 is an N pole. In the first magnetic device 600a, the polarity facing the -x direction may be an N pole. In addition, in the second magnetic device 600b, the polarity facing the +y direction may be an N pole.

[0079] For example, when the battery tray 100 moves in the +x direction and approaches the first stopper 500a, the first magnetic unit 130a, the second magnetic unit 130b, and the first magnetic device 600a may become closer. In this case, a repulsive force may act between the first magnetic unit 130a and the first magnetic device 600a and between the second magnetic unit 130b and the first magnetic device 600a. Therefore, the impact amount of the battery tray 100 and the first magnetic device 600a can be reduced.

[0080] As another example, when the battery tray 100 moves in the -y direction and becomes closer to the second stopper 500b, the third magnetic unit 130c, the fourth magnetic unit 130d, and the second magnetic device 600b may become closer. In this case, a repulsive force may act between the third magnetic unit 130c and the second magnetic device 600b and between the fourth magnetic unit 130d and the second magnetic device 600b. Therefore, the impact amount of the battery tray 100 and the second magnetic device 600b can be reduced.

[0081] The battery conveying system 10 has the advantage of effectively reducing the impact applied to the battery tray 100 while guiding the moving direction of the battery tray 100 so that the battery tray 100 is not separated from the conveying device 200. Therefore, in the process of conveying batteries through the battery tray 100, the possibility of battery defects due to impact can be significantly reduced.

[0082] Next, we will use Figure 7 An implementation manner in which the control device 400 controls the operating state of the magnetic device 600 is described below.

[0083] exist Figure 7 In an embodiment of the present invention, the first communication device 300a, the second communication device 300b, and the third communication device 300c may be connected to communicate with the communication unit 150 of the battery tray 100. In addition, each of the first communication device 300a, the second communication device 300b, and the third communication device 300c may 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.

[0084] The control device 400 can determine the position of the battery tray 100 in the conveying device 200 based on R1, R2 and R3. Specifically, the control device 400 can determine the position of the battery tray 100 according to the trilateral measurement method 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.

[0085] 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 stopping device 500 .

[0086] Specifically, the control device 400 may be configured to control the operating state of the magnetic device 600 so that when the distance between the position of the battery tray 100 and the position of the stopper 500 is less than or equal to a preset reference distance, the magnetic device 600 exhibits magnetism. Preferably, the control device 400 may control the operating state of the magnetic device 600 so that when the distance between the position of the battery tray 100 and the position of the stopper 500 reaches a preset reference distance, the magnetic device 600 exhibits magnetism.

[0087] Hereinafter, since the magnetic device 600 is attached to the outer surface of the stopping device 500 , it is assumed that the position of the stopping device 500 and the position of the magnetic device 600 are substantially the same.

[0088] Specifically, the control device 400 may calculate the distance between the determined position of the battery tray 100 and the position where the stopper 500 is mounted.

[0089] For example, in Figure 7In the embodiment of the present invention, the control device 400 may calculate the distance between the position of the battery tray 100 and the first stopper 500a as R4. Preferably, since the battery tray 100 moves toward the first stopper 500a in the +x direction, the distance between the battery tray 100 and the second stopper 500b may not be calculated. In other words, the control device 400 may calculate the distance between the stopper 500 and the battery tray 100 at the closest position in the direction in which the battery tray 100 travels.

[0090] In addition, the control device 400 may compare the calculated distance (the distance between the battery tray 100 and the stopper 500) with a preset reference distance. Here, when the control device 400 controls the operation of the magnetic device 600, the reference distance may be preset as a minimum distance at which the magnetic force generated by the magnetic device 600 can be maximized before the battery tray 100 reaches the magnetic device 600. That is, the reference distance may be set in advance for the conveying device 200 based on a preset unit conveying distance (e.g., conveying distance per second) and the time from the time point when the operation of the magnetic device 600 is changed to the time point indicating the maximum magnetic force.

[0091] For example, in Figure 7 In the embodiment, when R4 reaches the preset reference distance, the control device 400 can change the operating state of the first magnetic device 600a so that the first magnetic device 600a exhibits magnetism.

[0092] The control device 400 can control the operation state of the magnetic device 600 to be an on state or an off state. The on state refers to a state in which current flows through the magnetic device 600 and the magnetic device 600 exhibits magnetism according to the current. The off state refers to a state in which no current flows to the magnetic device 600 and the magnetic device 600 does not exhibit magnetism.

[0093] Here, the current direction in the on state may be preset to a direction in which the polarity of the magnetic device 600 facing the battery tray 100 is the same as the polarity of the magnetic unit 130 facing the outside of the housing 110. For example, assume that the polarity of the magnetic unit 130 facing the outside of the housing 110 is the N pole, and the polarity of the magnetic unit 30 facing the inside of the housing 110 is the S pole. The current direction in the on state may be preset so that the polarity of the magnetic device 600 facing the battery tray 100 is the N pole, and the polarity of the magnetic device 600 facing the stopper 500 is the S pole.

[0094] Because if the state of the magnetic device 600 remains in the on state even if the battery tray 100 has not reached the stopping device 500, unnecessary energy is consumed, so if the distance between the battery tray 100 and the stopping device 500 is less than or equal to the reference distance, the control device 400 can control the operating state of the magnetic device 600 to the on state.

[0095] The battery transfer system 10 prevents unnecessary resource consumption and can reduce the amount of impact applied to the battery tray 100. Therefore, the batteries can be transferred safely and efficiently.

[0096] The communication device 300 may be configured to receive the transmission information from the communication unit 150 and calculate the amount of impact applied to the battery tray 100 based on the received transmission information.

[0097] Specifically, the communication device 300 may 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 may calculate the amount of impact applied to the battery tray 100 based on the acceleration information and the angular velocity information.

[0098] Furthermore, the communication device 300 may transmit impact amount information regarding the calculated impact amount to the control device 400 .

[0099] 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 when the impact amount calculated by the communication device 300 is greater than or equal to a preset threshold impact amount.

[0100] Specifically, the threshold impact amount may be pre-set to an impact amount that may cause defects in the battery. For example, if the impact amount is greater than or equal to the threshold impact amount, cracks may occur in the battery.

[0101] If the calculated impact amount is greater than or equal to the threshold impact amount, the control device 400 may change the communication cycle and the measurement cycle to more accurately detect the position of the battery tray 100. Preferably, the control device 400 may change the communication cycle so as to shorten the communication cycle between the communication unit 150 and the communication device 300, and change the measurement cycle so as to shorten the measurement cycle of the measurement unit 140. In other words, the transmission information of the battery tray 100 may be measured more frequently according to the shortened measurement cycle, and the transmission information may be sent to the communication device 300 faster than before according to the shortened communication cycle. Because the control device 400 may receive the distance information of the battery tray 100 from the communication device 300 faster than before, the control device 400 may determine the position of the battery tray 100 in the transmission device 200 within a shorter cycle than before.

[0102] Furthermore, if the calculated impact amount is greater than or equal to the threshold impact amount, the control device 400 may be configured to further change the communication strength of the communication unit 150 .

[0103] Reference Figure 3 , the battery delivery system 10 may further include an alarm device 700 .

[0104] The alarm device 700 may be configured to receive a signal output from the communication unit 150, and emit light or flash when the strength of the received signal is greater than or equal to a preset threshold strength. Specifically, if the calculated impact amount is greater than or equal to the threshold impact amount, the control device 400 may change the communication strength of the communication unit 150 to be greater than or equal to the threshold strength. That is, a signal having a strength greater than or equal to the threshold strength may be output from the communication unit 150. Therefore, a user or a worker can easily check whether the battery tray 100 conveyed by the conveying device 200 has a defect by checking the alarm device 700.
