Description

Battery transport robot and battery freezing processing system and method using the same

[0001] The present disclosure relates to a battery transport robot for recycling secondary batteries and a battery freezing treatment system and method using the same.

[0002] As demand for electric vehicles grows, the disposal of waste batteries generated from them is becoming a major social issue. Lithium secondary batteries, the primary raw material for waste batteries, contain organic solvents, explosive substances, and heavy metals such as nickel, cobalt, manganese, and iron. Ni, cobalt, manganese, and lithium are valuable metals with high scarcity value. Therefore, the recovery and recycling processes for discarded lithium secondary batteries are emerging as a key research area.

[0003] Recycling methods for used batteries can be broadly categorized into physical decomposition, oxidation-drying, and non-oxidative high-temperature refining. The first method, physical decomposition, suffers from a very low lithium recovery rate. The oxidation-drying method, on the other hand, has the drawback of high CO2 emissions, the generation of slag byproducts, and the loss of some lithium through volatilization during the refining process.

[0004] The non-oxidizing high-temperature refining process is a method to solve the problems of the above two processes by freezing the discharge-free batteries in packs or modules through a freezing process of -60 to -90 degrees Celsius, crushing them, and then going through an electrolyte stabilization process and high-temperature refining to create a reduced alloy in the form of fine powder, which is then separated into NCM alloy, lithium compound, and excess carbon.

[0005] This non-oxidizing high-temperature smelting method has the advantage of reducing CO2 emissions and slag byproducts and minimizing lithium loss, but there is a problem in that it is difficult for workers to feed waste batteries in packs or modules into the freezing process due to the weight of the batteries, which range from 30 to 180 kg.

[0006] One aspect of the disclosed embodiment provides a battery transfer robot that acquires batteries to be input into a freezing process, stores the input history of the batteries, and inputs them into a freezing process in a non-oxidizing high-temperature smelting method, and a battery freezing treatment system and method using the same.

Therefore, when a part is said to "comprise" a certain component, this does not mean that other components are excluded, but rather that other components may be included, unless specifically stated otherwise.

[0043] Additionally, throughout the specification, when we say "in plan", we mean when the target portion is viewed from above, and when we say "in cross section", we mean when the target portion is viewed from the side in a cross-section cut vertically.

[0044] Throughout the specification, when a part is said to be "coupled" to another part, this includes not only "directly or physically coupled" but also "indirectly or non-contact coupled" with another element in between.

[0045] Additionally, throughout the specification, when we say "connected," this does not only mean that two or more components are directly connected, but also that two or more components are indirectly connected through other components, that they are electrically connected in addition to being physically connected, or that they are referred to by different names depending on location or function but are one.

[0046] FIG. 1 is a perspective view of a battery freezing treatment system according to one embodiment, FIG. 2 is a front view of a freezing treatment system according to one embodiment, FIG. 3 is a perspective view of a battery storage box according to one embodiment, FIG. 4 is a front view of a battery storage box according to one embodiment, FIG. 5 is a perspective view of a freezing treatment box according to one embodiment, and FIG. 6 is a front view of a freezing treatment box according to one embodiment.

[0047] Referring to FIGS. 1 to 6, a battery freezing treatment system according to one embodiment of the present invention includes a chamber (10) for storing batteries requiring freezing treatment, a freezing treatment room (20) into which batteries stored in the chamber (10) are introduced and frozen, and a battery transport robot (30) for introducing batteries stored in the chamber (10) into the freezing treatment room (20).

[0048] The antechamber (10) is a sealed space maintained at a sub-zero temperature, and a battery storage compartment (11) is installed. The battery storage compartment (11) is composed of a number of compartments arranged in a number of rows and columns, and each compartment stores a single battery or a dummy for system maintenance. Batteries can be loaded into the battery storage compartment (11) by manpower or a conveyor belt.

[0049] A pair of multi-stage guides (111) are installed at the bottom of each of the multiple compartments of the battery storage box (11). The pair of multi-stage guides (111) are formed to have multiple stages so that batteries of various sizes can be placed.

[0050] A stopper (not shown) for fixing the position of the loaded battery and a proximity sensor (not shown) for detecting the presence or absence of the battery may be installed at the end of the multi-stage guide (111).

[0051] The freezing treatment room (20) is installed in the form of a sealed housing maintained at an ultra-low temperature, and a battery is inserted through the inlet (23) of the housing (22) and discharged through the outlet (24) on the opposite side. The inlet (23) and outlet (24) can be opened and closed in a sliding manner by a signal from a central control device (not shown).

[0052] In the freezing treatment room (20), a freezing treatment box (21) is installed to store batteries undergoing freezing treatment. The freezing treatment box (21) is composed of multiple layers, and multiple batteries can be placed on each layer.

[0053] A sliding guide (211) is installed on both sides in the longitudinal direction of each layer of the freezer (21). The sliding guide (211) guides the batteries to be inserted into the freezer (21) and the batteries that have been processed in the freezer (21) to slide and move. The sliding guide (211) can protrude from the longitudinal front and rear of the freezer (21), thereby enabling more stable insertion and ejection of batteries in the freezer (21). In addition, the sliding guide (211) is formed to have a plurality of stages so that batteries of various sizes can be arranged, similar to the multi-stage guide (111) of the battery storage box (11).

[0054] The batteries that are put into the freezer (20) are operated in a first-in, first-out manner, where the first battery put in is taken out first. That is, when a battery is put in at the inlet side of each stage of the freezer (21), the battery at the outlet side is pushed out and discharged.

[0055] Batteries discharged from the freezing treatment room (20) are moved to the shredding process room (40). After freezing, the discharged batteries are obtained by a robot installed in front of the shredding process, and the type of battery is determined again, and the batteries are safely transported to the desired location according to the type of battery.

[0056] FIG. 7 is a perspective view of a battery transport robot according to one embodiment, and FIG. 8 is a front view of a battery transport robot according to one embodiment.

[0057] Referring to FIGS. 7 and 8, a battery transport robot (30) is installed in the front room (10) and is positioned between the battery storage box (11) and the freezer room (20). The robot takes out batteries one by one from the battery storage box (11) and places them in the freezer room (21) of the freezer room (20).

[0058] The battery transport robot (30) is composed of a three-axis linear drive module (31, 32, 34), an R-axis drive module (33), a battery support (35), and a pusher module (36).

[0059] Specifically, it includes an X-axis drive module (31) installed so as to be movable in the longitudinal direction (x-axis) of the battery storage box (11) or the width direction (x-axis) of the freezer (21), a Y-axis drive module (32) installed on the upper part of the X-axis drive module (31), an R-axis drive module (33) installed on the upper part of the Y-axis drive module (32) so as to be rotatably installed in the direction of the battery storage box (11) or the direction of the freezer (21), a Z-axis drive module (34) installed on the upper part of the R-axis drive module (33) and raised and lowered in the up-and-down direction (z-axis), a battery supporter (35) coupled to the Z-axis drive module (34), and a pusher module (36) that pressurizes a battery loaded on the battery supporter (35) and introduces it into the freezer (20).

[0060] The X-axis drive module (31) includes an X-axis transfer guide (311) installed on the upper portion of the support, an X-axis transfer plate (312) that runs along the X-axis transfer guide (311), and an X-axis LM (Linear Motor) guide (313) that is connected to the X-axis transfer plate (312) and driven by a servo motor. The battery support (35) can be moved left and right in the battery storage box (11) by the X-axis drive module (31) to be positioned in the row where the battery to be taken out is located.

[0061] The Y-axis drive module (32) includes a Y-axis transfer guide (321) installed on the upper portion of the X-axis transfer plate (312), a Y-axis transfer plate (322) that runs along the Y-axis transfer guide (321), and a Y-axis LM guide (323) that is connected to the Y-axis transfer plate (322) and driven by a servo motor. The Y-axis drive module (32) can move the battery support (35) in the width direction (y-axis) of the battery storage box (11) so that the battery support (35) can be positioned under the battery to be taken out. In addition, the Y-axis drive module (32) can move the battery support (35) in the length direction (y-axis) of the freezer (21) so that the battery support (35) can be positioned in the freezer (21).

[0062] The R-axis drive module (33) includes a rotation shaft (331) installed on the upper portion of the Y-axis transfer plate (322), an R-axis rotation plate (332) connected to the upper portion of the rotation shaft (331), and an R-axis drive motor (333) that provides driving force to the rotation shaft (331). The battery support (35) can change direction toward the battery storage box (11) or the freezer box (21) by the R-axis drive module (33).

[0063] The Z-axis drive module (34) includes a Z-axis transfer guide (341) installed vertically on the R-axis rotation plate (332), a Z-axis transfer plate (342) that runs along the Z-axis transfer guide (341), and a Z-axis LM guide (343) that is connected to the Z-axis transfer plate (342) and driven by a servo motor. The Z-axis drive module (34) can elevate the battery support (35) so that the battery support (35) can be positioned in a compartment where a battery to be taken out is located in the battery storage box (11), or positioned in a floor where a battery to be inserted is to be placed in the freezer (21).

[0064] The battery support (35) is connected to the Z-axis transfer plate (342) and is raised and lowered by the Z-axis drive module (34). A proximity sensor (351) for detecting whether a battery is loaded and a load cell (not shown) for measuring the weight of the battery are installed on the battery support (35).

[0065] The pusher module (36) includes a push member (361) that is slidably connected to the upper portion of the battery support (35), and a pusher shaft LM guide (362) that is connected to the push member (361) and driven by a servo motor. The push member (361) moves forward by the LM guide (362) and pushes the battery loaded on the battery support (15) and places it into the freezer (21).

[0066] Below, the operation process of a battery refrigeration system according to one embodiment is described in detail.

[0067] FIG. 9 is a flowchart of a battery ultra-low temperature freezing treatment method according to one embodiment, and FIG. 10 is an exemplary diagram showing the order of putting a battery into a freezing treatment room according to one embodiment.

[0068] Referring to Fig. 9, when system operation begins, a system check process (S10) is performed. The system check is performed by the central control unit, and checks are made for whether the temperature of the front room (10) and the cold treatment room (20) are below the set temperature, the location and operating status of the battery transport robot (30), and whether there is an input space in the cold treatment room (21).

[0069] In the step (S20) of checking whether the freezing time has arrived, the arrival of the freezing time of the first inserted battery is checked. The freezing time can be preset, and as described below, the freezing treatment intensity can be adjusted based on the weight of the battery to check whether the preset freezing time has arrived.

[0070] When a battery that has completed freezing is found among the batteries placed in the freezing treatment room (20), the location of the frozen battery in the freezing treatment box (21) is transmitted to the battery transfer robot (30) (S30).

[0071] Next, whether batteries are loaded in the battery storage compartment (11) is checked (S40). If there are no batteries to be removed, batteries are loaded by manpower or the operation of a conveyor belt. At this time, it can be checked whether the batteries loaded in the battery storage compartment (11) match the type of battery previously input by the driver. The type of battery loaded in the battery storage compartment (11) and whether it is a dummy battery are input by the driver and stored in the battery transport robot (30).

[0072] When the battery supply process begins, the battery transport robot (30) retrieves the batteries to be frozen from the battery storage box (11) (S50). Specifically, the battery transport robot (30) drives the multi-axis drive module to position itself in front of the batteries to be frozen in the battery storage box (11) of the front room (10) in a preset order, and lifts and retrieves the batteries to be frozen as the battery support (15) rises from the bottom to the top of the batteries to be frozen. At this time, the battery transport robot (30) determines whether they are batteries or dummy (wooden) through a proximity sensor (351) that checks the magnetism attached to the battery support (15). Through this, information can be obtained to determine whether they are batteries or dummy batteries in the next process and then decide whether to shred them.

[0073] When a battery to be frozen is placed on the battery support (15) of the battery transport robot (30), the weight of the battery to be frozen is measured by a load cell installed on the battery support (15) (S60).

[0074] When the weight of the battery to be frozen is measured, the freezing treatment intensity of the freezing treatment box (21) is determined based on this weight (S70). The determination of the freezing treatment intensity and the control of the freezing process of the freezing treatment box (21) accordingly can be performed by the central control unit of the system. The central control unit can monitor the temperature of the freezing treatment box (21). That is, when the temperature of the freezing treatment box (21) is lower than a preset freezing temperature (hereinafter referred to as “set temperature”), the freezing can be stopped or the intensity can be weakened until the temperature of the freezing treatment box (21) reaches (heats up) the set temperature, and when the temperature of the freezing treatment box (21) is higher than the set temperature, the freezing can be strengthened until the temperature of the freezing treatment box (21) reaches (cools down) the set temperature. Therefore, the central control unit can calculate the effect on the temperature inside the freezing treatment box (21) based on the weight of the battery to be frozen, and can control the freezing intensity of the freezing treatment box (21) in various ways, such as strengthening, weakening, or stopping, accordingly. Additionally, the battery weight can be managed before / after freezing and before / after crushing by measuring the battery weight again after crushing.

[0075] When the battery transport robot (30) takes out and transports the battery to be frozen, the inlet (23) and outlet (24) of the freezing treatment room (20) are opened (S80).

[0076] The battery transport robot (30) that lifts the battery scheduled to be frozen changes direction toward the freezing treatment room (20) by the R-axis drive module (33) and moves to the position of the stage where the frozen battery is placed in the freezing treatment room (20) by the drive of the three-axis linear axis.

[0077] Thereafter, the pusher module (36) operates to push the batteries scheduled for freezing mounted on the battery support (35) and place them on the corresponding floor of the freezing treatment room (21) (S90). At this time, the batteries that have completed freezing on the rear side of the same floor are pushed by the introduction of the batteries scheduled for freezing and are discharged from the freezing treatment room (20) and moved to the crushing process room (40) (S100).

[0078] When the introduction of the battery to be frozen into the freezing treatment room (20) is completed, the inlet (23) and the outlet (24) of the freezing treatment room (20) are closed (S110). When the inlet (23) and the outlet (24) of the freezing treatment room (20) are closed, the freezing of the battery in the freezing treatment room (20) is performed according to the freezing treatment intensity determined according to the weight of the battery to be frozen (S120). For example, the introduction time and weight of the battery introduced into the freezing treatment room (20) are automatically stored, the freezing treatment intensity is determined according to the weight, and the freezing of the freezing treatment box (21) is performed according to the freezing treatment intensity. Here, since the freezing treatment intensity is adjusted according to the weight of the battery introduced into the freezing treatment box (21), the batteries in the freezing treatment box (21) require the same freezing time regardless of the weight, and thus can be controlled to be discharged according to the order in which they were introduced. The time spent in the freezing process is automatically recorded and managed by the central control unit, and the time for insertion and discharge of the battery can be controlled according to the set freezing time.

[0079] Referring to Figure 10, the order of battery insertion in the battery storage compartment is determined by the order of withdrawal from the bottom to the top, and the order of left / right is determined by the driver's preference. Similarly, batteries inserted into the refrigeration process are operated on a first-in / first-out basis, with the first battery inserted first being removed.

[0080] Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made within the scope of the claims, the description of the invention, and the attached drawings, and it is obvious that this also falls within the scope of the present invention.
