Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling equipment, in particular to a cooling device and a battery disassembly system. Background Art

[0002] During the recycling and disassembly of waste lithium batteries, after removing the outer shell, high and low voltage wire harnesses, battery management system (Battery Management System, BMS), cooling plate and bus bar of the lithium battery, the battery cells of the lithium battery still adhere to the battery pack bottom plate. Moreover, the battery cells are closely arranged in the battery pack, and there is no space on the battery pack for physically separating the battery cells. If disassembled violently, it is easy to damage the internal structure of the battery cells. Therefore, generally, the battery pack needs to be forklifted into the freezer manually. After the freezing is completed, the freezer door is opened manually, and a forklift is driven into the freezer to forklift it out of the warehouse. Since the battery pack has been cooled at a low temperature in the freezer for a period of time, the adhesive used to bond the battery cells to the battery pack bottom plate fails. After taking the battery pack out of the freezer, the battery cells can be separated from the battery pack by using the back vibration method. Since the above-mentioned process of separating the battery cells requires manual opening of the freezer and manual transfer of the battery pack, after placing enough battery packs in the freezer and the workers leave the freezer, the freezing components of the freezer are then turned on to cool the freezer, and then the battery packs are statically frozen. The whole process is inefficient. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a cooling device, which can solve the problem of low existing freezing efficiency, and also provides a battery disassembly system.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] In a first aspect, a cooling device includes:

[0006] A feed bin, including a first bin body and a feed gate, the feed gate is arranged at the inlet end of the first bin body;

[0007] A freezer, the inlet end of the freezer is connected to the outlet end of the first bin body;

[0008] A discharge bin, including a second bin body and a discharge gate, the discharge gate is arranged at the outlet end of the second bin body, and the inlet end of the second bin body is connected to the outlet end of the freezer;

[0009] A conveying track is arranged through the first bin body, the freezer and the second bin body to convey materials into the first bin body, the freezer and the second bin body in sequence;

[0010] An inlet gate is provided between the inlet end of the freezer and the outlet end of the first bin to connect or block the freezer and the first bin.

[0011] An outlet gate is provided between the outlet end of the freezer and the inlet end of the second bin to connect or block the freezer and the second bin.

[0012] The utility model has at least the following beneficial effects: The conveying track passes through the first bin, the freezer and the second bin. After the material is placed on the conveying track, the material can be sequentially transported to the first bin, the freezer and the second bin through the conveying track, which can replace manual transportation of the battery pack in and out of the freezer, greatly reducing the labor intensity of workers and improving the efficiency of transporting the battery pack in and out of the freezer, thereby improving the efficiency of disassembling the battery pack and the battery core.

[0013] Moreover, due to the provision of the feeding bin and the discharging bin, when the inlet gate is opened, the battery pack can enter the freezer, and the feeding gate can block the inlet end of the freezer, reducing the influence of the external environmental air on the internal temperature of the freezer. During the process of the battery pack entering the freezer, the battery packs inside the freezer can be continuously cooled to improve the utilization efficiency of the freezer; when the outlet gate is opened, the battery pack can leave the freezer, and the discharging gate of the discharging bin can block the outlet end of the freezer, reducing the influence of the external environmental air on the internal temperature of the freezer. During the process of the battery pack leaving the freezer, the battery packs inside the freezer can be continuously cooled to improve the utilization efficiency of the freezer and the cooling efficiency of the battery pack.

[0014] As a further improvement of the above technical solution, the cooling device further includes:

[0015] A controller, which is electrically connected to the feeding gate, the inlet gate, the outlet gate and the discharging gate respectively, and is used to control the opening or closing of the feeding gate, the inlet gate, the outlet gate and the discharging gate.

[0016] By providing the controller, the feeding gate, the inlet gate, the outlet gate and the discharging gate can be automatically controlled, further reducing the labor intensity of workers, and also being able to better coordinate the opening timing of the feeding gate, the inlet gate, the outlet gate and the discharging gate. During the process of the material entering and leaving the freezer, the feeding gate and the discharging gate are in the closed state, reducing the influence of the external environmental hot air on the internal temperature of the freezer.

[0017] As a further improvement of the above technical solution, the cooling device further includes:

[0018] A plurality of position sensors are respectively arranged at the feeding gate, the inlet gate, the outlet gate and the discharging gate, and the plurality of position sensors are electrically connected to the controller respectively; when the position sensor detects that the material is approaching, the controller controls the feeding gate, the inlet gate, the outlet gate or the discharging gate corresponding to the position sensor to open; when the position sensor detects that the material is moving away, the controller controls the feeding gate, the inlet gate, the outlet gate or the discharging gate corresponding to the position sensor to close.

[0019] The position sensor can detect the position information of the material, and the controller can automatically control the opening or closing of the feeding gate, the inlet gate, the outlet gate and the discharging gate according to the position information of the material obtained by the position sensor, further reducing the labor intensity of workers.

[0020] As a further improvement of the above technical solution, the cooling device further includes:

[0021] A plurality of heating wires are respectively arranged between the first bin body and the feeding gate, between the second bin body and the discharging gate, between the inlet gate and the freezer, and between the outlet gate and the freezer, and the heating wires are used to heat the feeding gate, the discharging gate, the inlet gate and the outlet gate.

[0022] The heating wires can heat the feeding gate, the discharging gate, the inlet gate and the outlet gate, thereby avoiding the situation of condensate freezing, and further ensuring that the feeding gate, the discharging gate, the inlet gate and the outlet gate can be opened smoothly.

[0023] As a further improvement of the above technical solution, the cooling device further includes:

[0024] A heat preservation layer is arranged on the inner walls of the first bin body, the second bin body and the freezer.

[0025] The setting of the heat preservation layer can reduce the influence of the external environmental air on the internal temperatures of the first bin body, the second bin body and the freezer, reduce the heat exchange between the first bin body, the second bin body, the freezer and the environment, and thus reduce the energy consumption of the freezer for refrigeration.

[0026] As a further improvement of the above technical solution, the freezer includes a freezing chamber, an evaporator, a throttle valve, a condenser and a compressor. The evaporator is arranged in the freezing chamber. The outlet end of the compressor is connected to the inlet end of the condenser. The outlet end of the condenser is connected to the inlet end of the throttle valve. The outlet end of the throttle valve is connected to the inlet end of the evaporator. The outlet end of the evaporator is connected to the inlet end of the compressor.

[0027] The compressor operates, and the refrigerant is converted into superheated steam at high temperature and high pressure by the compressor and flows to the condenser for constant-pressure cooling. The refrigerant passing through the condenser is transformed into a high-pressure and low-temperature liquid and flows to the throttle valve. After being regulated by the throttle valve, the refrigerant becomes a low-pressure liquid and then flows to the evaporator located in the freezer. The refrigerant absorbs heat and vaporizes, causing the temperature in the freezer to drop, thereby realizing the freezing treatment of the materials in the freezer.

[0028] As a further improvement of the above technical solution, the freezer further includes a thermostat. The thermostat is provided with a temperature-sensing probe for detecting the temperature in the freezer. The thermostat is electrically connected to the compressor and is configured to control the start or stop of the compressor according to the temperature in the freezer.

[0029] The thermostat can control the start and stop of the compressor according to the temperature in the freezer, which can reduce the energy consumption of refrigeration while ensuring that the temperature in the freezer remains at the preset refrigeration temperature.

[0030] As a further improvement of the above technical solution, the freezer is arranged along the extension direction of the conveying track, and the evaporator is arranged on the inner side wall of the freezer and along the extension direction of the freezer.

[0031] With such an arrangement, the materials can be refrigerated at all positions in the freezer, the cooling duration of the materials can reach the preset standard duration, and continuous warehousing of the freezer can be realized, improving the utilization efficiency of the freezer.

[0032] As a further improvement of the above technical solution, the conveying track includes a feeding conveyor line, a freezing conveyor line, and a discharging conveyor line. The freezing conveyor line passes through the freezer. The inlet end of the freezing conveyor line extends to the first bin body, and the outlet end of the freezing conveyor line extends to the second bin body. The outlet end of the feeding conveyor line is arranged opposite to the inlet end of the freezing conveyor line, and the outlet end of the freezing conveyor line is arranged opposite to the inlet end of the discharging conveyor line. The feeding conveyor line, the freezing conveyor line, and the discharging conveyor line can all adjust the material conveying route according to the actual situation of the workshop, which is more conducive to the layout of the conveying track in the workshop.

[0033] In a second aspect, a battery disassembly system includes a cooling device as described in any one of the above technical solutions.

[0034] During the process of cell separation, the battery pack can automatically enter and exit the freezer under the action of the conveying track, which can greatly improve the cooling efficiency. Moreover, workers do not need to enter and exit the freezer, which can avoid the harm to the workers' bodies caused by the low-temperature environment of the freezer and also greatly reduce the labor intensity of the workers. In addition, during the process of the battery pack entering and exiting the freezer, since both the discharge gate and the feed gate are in the closed state, the freezer is isolated from the outside world, which can reduce the influence of external hot air on the internal temperature of the freezer when materials enter and exit the freezer. The internal temperature of the freezer is maintained within the preset temperature range, and the existing materials inside the freezer can be cooled normally to improve the utilization efficiency of the freezer and the cooling efficiency of the battery pack.

[0044] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present utility model. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

[0045] In the first aspect, referring to Figure 1 , an embodiment of the present utility model provides a cooling device for cooling materials, such as cooling a battery pack adhered with an electric core. During the cooling process, there is no need for manual entry and exit of the freezer 200 to transport the battery pack, which can improve the cooling efficiency of the battery pack and reduce the energy loss during the process of transporting the battery pack into the freezer 200.

[0046] In this embodiment, the cooling device includes a feeding bin 100, a freezer 200, a discharging bin 300, and a conveying track 400. The feeding bin 100 and the discharging bin 300 are respectively arranged at the inlet end and the outlet end of the freezer 200. Among them, the feeding bin 100 includes a first bin body 110 and a feeding gate 120. The feeding gate 120 is arranged at the inlet end of the first bin body 110 for opening or closing the inlet end of the first bin body 110, and the outlet end of the first bin body 110 is connected to the inlet end of the freezer 200. The discharging bin 300 includes a second bin body 310 and a discharging gate 320. The inlet end of the second bin body 310 is connected to the outlet end of the freezer 200, and the discharging gate 320 is arranged at the outlet end of the second bin body 310 for opening or closing the outlet end of the second bin body 310.

[0047] The conveying track 400 passes through the first bin 110, the freezer 200 and the second bin 310. Materials can be placed on the upper surface of the conveying track 400. Under the driving action of the conveying track 400, the materials placed on the conveying track 400 can successively enter the first bin 110, the freezer 200 and the second bin 310, which can replace manual conveyance of the battery packs in and out of the freezer 200, greatly reducing the labor intensity of workers and improving the efficiency of conveying the battery packs in and out of the freezer 200, thereby improving the efficiency of disassembling the battery packs and the battery cells.

[0048] In this embodiment, the cooling device further includes an inlet gate 500 and an outlet gate 600. The inlet gate 500 is arranged between the inlet end of the freezer 200 and the outlet end of the first bin 110. When the inlet gate 500 is opened, the first bin 110 is communicated with the freezer 200, and materials can move from the first bin 110 to the freezer 200 under the action of the conveying track 400. When the inlet gate 500 is closed, the first bin 110 and the freezer 200 are blocked from each other. The outlet gate 600 is arranged between the outlet end of the freezer 200 and the inlet end of the second bin 310. When the outlet gate 600 is opened, the second bin 310 is communicated with the freezer 200, and materials can move from the freezer 200 to the second bin 310 under the action of the conveying track 400. When the outlet gate 600 is closed, the second bin 310 and the freezer 200 are blocked from each other.

[0049] During the use process, the materials are sequentially moved to the first bin 110, the freezer 200, and the second bin 310 under the action of the conveying track 400. Specifically, when the materials move along the conveying track 400 to the inlet end of the first bin 110, the feeding gate 120 opens, and the materials can enter the first bin 110, while the inlet gate 500, the outlet gate 600, and the discharging gate 320 are all closed. When the materials completely enter the first bin 110, the feeding gate 120 closes. When the materials move along the conveying track 400 to the outlet end of the first bin 110, the inlet gate 500 opens, and the materials can enter the freezer 200, and the outlet gate 600, the discharging gate 320, and the feeding gate 120 are all in the closed state. After the materials completely enter the freezer 200, the inlet gate 500 closes, and the materials are cooled in the freezer 200. When the materials move along the conveying track 400 to the outlet end of the freezer 200, the outlet gate 600 opens, and the materials can leave the freezer 200 and enter the second bin 310. At this time, the discharging gate 320, the inlet gate 500, and the feeding gate 120 are all in the closed state. After the materials completely leave the freezer 200 and enter the second bin 310, the outlet gate 600 closes. When the materials move along the conveying track 400 to the outlet end of the second bin 310, the discharging gate 320 opens, and the materials can leave the second bin 310 and enter the next process.

[0050] It can be understood that during the process of the materials entering and leaving the freezer 200, since both the discharging gate 320 and the feeding gate 120 are in the closed state, the freezer 200 is in an isolated state from the outside world, which can reduce the influence of the outside hot air on the internal temperature of the freezer 200 when the materials enter and leave the freezer 200. The internal temperature of the freezer 200 is maintained within a preset temperature range. During the process of the materials entering the freezer 200, the existing materials inside the freezer 200 can be cooled normally without being affected by the newly incoming materials, which can realize the continuous warehousing of the materials and improve the utilization efficiency of the freezer 200.

[0051] In some embodiments, the cooling device further includes a controller, which is electrically connected to the feeding gate 120, the inlet gate 500, and the outlet gate 600 respectively. The controller is configured to control the opening or closing of the feeding gate 120, the inlet gate 500, the outlet gate 600, and the discharging gate 320.

[0052] By setting the controller, the feeding gate 120, the inlet gate 500, the outlet gate 600, and the discharging gate 320 can be automatically controlled, which further reduces the labor intensity of workers and can also better coordinate the opening timing of the feeding gate 120, the inlet gate 500, the outlet gate 600, and the discharging gate 320. During the process of the materials entering and leaving the freezer 200, the feeding gate 120 and the discharging gate 320 are in the closed state, reducing the influence of the outside hot air on the internal temperature of the freezer 200.

[0053] It is understandable that the controller can be a single-chip microcomputer, a PLC controller, etc., as long as it can implement the function of simply controlling the opening or closing of the feeding gate 120, the inlet gate 500, the outlet gate 600, and the discharging gate 320. In this embodiment, the controller is a PLC controller, and the feeding gate 120, the inlet gate 500, the outlet gate 600, and the discharging gate 320 are controlled to open or close through a PLC program.

[0054] In some embodiments, the cooling device further includes a plurality of position sensors. The position sensors can detect the position information of the material, and each position sensor is electrically connected to the controller and is respectively arranged at the feeding gate 120, the inlet gate 500, the outlet gate 600, and the discharging gate 320.

[0055] When the material approaches the feeding gate 120, the position sensor located on the feeding gate 120 can detect the approach of the material and transmit the position information of the material to the controller. The controller controls the feeding gate 120 to open, so that the material can smoothly enter the first bin 110. When the material completely enters the first bin 110, the position sensor located on the feeding gate 120 detects that the material gradually moves away and transmits the position information of the material to the controller. The controller controls the feeding gate 120 to close.

[0056] When the material approaches the inlet gate 500, the position sensor located on the inlet gate 500 can detect the approach of the material and transmit the position information of the material to the controller. The controller controls the inlet gate 500 to open, so that the material can smoothly enter the freezer 200. When the material completely enters the freezer 200, the position sensor located on the inlet gate 500 detects that the material gradually moves away and transmits the position information of the material to the controller. The controller controls the inlet gate 500 to close.

[0057] When the material approaches the outlet gate 600, the position sensor located on the outlet gate 600 can detect the approach of the material and transmit the position information of the material to the controller. The controller controls the outlet gate 600 to open, so that the material can smoothly leave the freezer 200 and enter the second bin 310. When the material completely leaves the freezer 200 and enters the second bin 310, the position sensor located on the outlet gate 600 detects that the material gradually moves away and transmits the position information of the material to the controller. The controller controls the outlet gate 600 to close.

[0058] When the material approaches the discharge gate 320, the position sensor located on the discharge gate 320 can detect the approach of the material and transmit the position information of the material to the controller. The controller controls the discharge gate 320 to open, so that the material can smoothly leave the second bin 310. After the material completely leaves the second bin 310, the position sensor located on the discharge gate 320 detects that the material is gradually moving away and transmits the position information of the material to the controller. The controller controls the discharge gate 320 to close.

[0059] It can be understood that the position sensor can be an electromagnetic sensor, an optoelectronic sensor or other types of sensors, which are not specifically limited here. By monitoring the position information of the material through the position sensor, the automatic opening or closing of the feed gate 120, the inlet gate 500, the outlet gate 600 and the discharge gate 320 can be realized, without the need for workers to operate the opening or closing of the feed gate 120, the inlet gate 500, the outlet gate 600 and the discharge gate 320. Further, the labor intensity of the workers is reduced, and the timing of opening or closing the feed gate 120, the inlet gate 500, the outlet gate 600 and the discharge gate 320 can be controlled more accurately.

[0060] Refer to Figure 2 , in some embodiments, the cooling device further includes heating wires 700. There are multiple heating wires 700, and heating wires 700 are provided between the first bin 110 and the feed gate 120, between the second bin 310 and the discharge gate 320, between the inlet gate 500 and the freezer 200, and between the outlet gate 600 and the freezer 200. The heating wires 700 are used to heat the feed gate 120, the inlet gate 500, the outlet gate 600 and the discharge gate 320.

[0061] It can be understood that the water vapor in the air condenses into dew. There may be dew water at the joints between the first bin 110 and the feed gate 120, between the second bin 310 and the discharge gate 320, between the inlet gate 500 and the freezer 200, and between the outlet gate 600 and the freezer 200. When the dew water freezes under the action of the freezer 200, it will have a negative impact on the opening of the feed gate 120, the discharge gate 320, the inlet gate 500 and the outlet gate 600, and it is difficult to open the feed gate 120, the discharge gate 320, the inlet gate 500 and the outlet gate 600.

[0062] After the heating wires 700 are provided, the heating wires 700 can heat the feed gate 120, the discharge gate 320, the inlet gate 500 and the outlet gate 600, thus avoiding the situation of dew water freezing, and further ensuring that the feed gate 120, the discharge gate 320, the inlet gate 500 and the outlet gate 600 can be smoothly opened.

[0063] In this embodiment, the heating wire 700 is a resistance heating wire 700.

[0064] Referring to Figure 3 , in some embodiments, the cooling device further includes a heat insulation layer 111, and the heat insulation layer 111 is disposed on the inner walls of the first chamber 110, the second chamber 310, and the freezer 200, and can insulate the first chamber 110, the second chamber 310, and the freezer 200, further avoiding the influence of external air on the internal temperature of the cooling device, reducing the heat exchange between the first chamber 110, the second chamber 310, the freezer 200 and the environment, and thus reducing the energy consumption of refrigeration in the freezer 200.

[0065] It can be understood that the material of the heat insulation layer 111 can be polyurethane foam, aerogel or vacuum insulation panel (VIP), which wraps the inner cavities of the first chamber 110, the second chamber 310, and the freezer 200.

[0066] In some embodiments, the freezer 200 includes a freezing chamber 210, an evaporator 220, a throttle valve 250, a condenser 240, and a compressor 230. Among them, the evaporator 220 is disposed in the freezing chamber 210, the outlet end of the compressor 230 is connected to the inlet end of the condenser 240, the outlet end of the condenser 240 is connected to the inlet end of the throttle valve 250, the outlet end of the throttle valve 250 is connected to the inlet end of the evaporator 220, the outlet end of the evaporator 220 is connected to the inlet end of the compressor 230, and the evaporator 220, the throttle valve 250, the condenser 240, and the compressor 230 form a closed refrigerant circuit, and the refrigerant can flow in this circuit to achieve refrigeration inside the freezing chamber 210.

[0067] When the compressor 230 operates, the refrigerant is converted into high-temperature and high-pressure superheated steam by the compressor 230 and flows to the condenser 240 for constant-pressure cooling. The refrigerant passing through the condenser 240 is transformed into high-pressure and low-temperature liquid and flows to the throttle valve 250. After being regulated by the throttle valve 250, the refrigerant becomes low-pressure liquid and then flows to the evaporator 220 located in the freezing chamber 210. The refrigerant absorbs heat and vaporizes, causing the temperature in the freezing chamber 210 to drop, and realizing the freezing treatment of the materials in the freezing chamber 210. The refrigerant flows into the compressor 230 for re-compression to complete one cycle.

[0068] In some embodiments, the freezer 200 further includes a thermostat. It can be understood that the thermostat is provided with a temperature sensing probe for detecting the temperature in the freezer compartment 210. The thermostat is electrically connected to the compression motor. The thermostat can control the start and stop of the compressor 230 according to the temperature in the freezer compartment 210, while ensuring that the temperature in the freezer compartment 210 is maintained at the preset refrigeration temperature and reducing the energy consumption of refrigeration.

[0069] In some embodiments, the freezer compartment 210 extends along the extension direction of the conveying track 400. The evaporator 220 is arranged on the inner side wall surface of the freezer compartment 210 and is arranged along the extension direction of the freezer compartment 210. With such an arrangement, the material can be cooled while moving in the freezer compartment 210. The material can be cooled at all positions in the freezer compartment 210. The cooling duration of the material can reach the preset standard duration, and continuous warehousing of the freezer compartment 210 can be realized, improving the use efficiency of the freezer 200.

[0070] In some embodiments, the conveying track 400 includes a loading conveying line, a freezing conveying line, and an unloading conveying line. Among them, the freezing conveying line passes through the freezer 200. The inlet end of the freezing conveying line extends to the first bin 110, and the outlet end of the freezing conveying line extends to the second bin 310. The inlet end of the freezing conveying line is arranged opposite to the outlet end of the loading conveying line, and the outlet end of the freezing conveying line is arranged opposite to the inlet end of the unloading conveying line.

[0071] It can be understood that since the conveying track 400 is divided into three sections, the loading conveying line, the freezing conveying line, and the unloading conveying line can all adjust the material conveying route according to the actual situation of the workshop, which is more conducive to the layout of the conveying track 400 in the workshop. In addition, the start, stop, and conveying speed of the loading conveying line, the freezing conveying line, and the unloading conveying line can be controlled separately. For example, when all the materials enter the freezing conveying line, the loading conveying line and the unloading conveying line can be stopped in time to reduce energy consumption. When all the materials enter the freezing conveying line, the conveying speed of the freezing conveying line can also be adjusted, such as reducing the conveying speed of the freezing conveying line to increase the time of the material in the freezer compartment 210 and ensure that the material is completely frozen.

[0085] The cooling device according to the embodiment of the present utility model can be used to cool the battery pack. After the battery pack is cooled by the refrigeration device, the adhesive between the battery pack and the battery cells fails, and the battery cells can be easily separated from the battery pack. The specific process of cooling the battery pack using the cooling device of this embodiment is as follows.

[0086] First, the battery pack with the battery cells attached is transported to the feeding conveyor line by a forklift or a manipulator. The feeding gate 120, the inlet gate 500, the outlet gate 600, and the discharging gate 320 are all in the closed state. When the battery pack moves to a position close to the feeding gate 120 through the transportation on the feeding conveyor line, the position sensor at the feeding gate 120 senses the approach of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the first driving component 122 of the feeding gate 120 to start, and the first door body 121 moves upward, so that the inlet end of the first bin 110 is opened, and the battery pack can smoothly enter the first bin 110 and move onto the freezing conveyor line.

[0087] After the battery pack completely enters the first bin 110, the position sensor on the feeding gate 120 detects the departure of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the first driving component 122 of the feeding gate 120 to start, and the first door body 121 moves downward, so that the inlet end of the first bin 110 is closed.

[0088] The battery pack is transported by the freezing conveyor line to the inlet end of the freezing chamber 210. The position sensor at the inlet gate 500 detects the approach of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the second driving component of the inlet gate 500 to start, and the second door body moves upward, so that the inlet end of the freezing chamber 210 is opened.

[0089] After the battery pack completely enters the freezing chamber 210, it continues to move under the action of the freezing conveyor line. The position sensor at the inlet gate 500 detects the departure of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the second driving component of the inlet gate 500 to start, and the second door body moves downward, and the inlet end of the freezing chamber 210 is closed, and the freezer 200 starts to freeze the battery pack.

[0090] The refrigerant is converted into high-temperature and high-pressure superheated steam under the action of the compressor 230 and flows into the condenser 240 for constant-pressure cooling. The refrigerant passing through the condenser 240 turns into high-pressure and low-temperature liquid and flows to the throttle valve 250. After being adjusted by the throttle valve 250, the refrigerant becomes low-pressure liquid and then flows to the evaporator 220 located in the freezing chamber 210. The refrigerant absorbs heat and vaporizes, causing the temperature in the freezing chamber 210 to drop, thereby realizing the freezing treatment of the battery pack in the freezing chamber 210.

[0091] The battery pack moves under the action of the freezing conveyor line and is frozen. When the battery pack moves to a position close to the outlet gate 600, the position sensor at the outlet gate 600 detects the approach of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the third driving component of the outlet gate 600 to start, and the third door moves upward, opening the outlet end of the freezing chamber 210. The battery pack can leave from the outlet end of the freezing chamber 210 and enter the second chamber 310.

[0092] When the battery pack completely enters the second chamber 310, the position sensor at the outlet gate 600 detects the departure of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the third driving component of the outlet gate 600 to start, and the third door moves downward, closing the outlet end of the freezing chamber 210.

[0093] When the battery pack continues to move under the action of the freezing conveyor line to a position close to the discharge gate 320, the position sensor at the discharge gate 320 detects the approach of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the fourth driving component of the discharge gate 320 to start, and the fourth door moves upward, opening the outlet end of the second chamber 310. The battery pack can be transferred from the freezing conveyor line to the discharge conveyor line and leave the second chamber 310.

[0094] When the battery pack completely leaves the second chamber 310, the position sensor at the discharge gate 320 detects the departure of the battery pack and transmits the position signal of the battery pack to the controller. The controller controls the fourth driving component of the discharge gate 320 to start, and the fourth door moves downward, closing the outlet end of the second chamber 310. The battery pack is transferred to the next working station under the action of the discharge conveyor line for the next process.

[0095] In a second aspect, an embodiment of the present invention provides a battery disassembling system, which includes the cooling device proposed in any one of the embodiments of the first aspect. Since the battery pack can automatically enter and exit the freezer 200 under the action of the conveying track 400 during the process of cell separation, the cooling efficiency can be greatly improved. Moreover, workers do not need to enter and exit the freezer 200, which can avoid the harm caused by the low-temperature environment of the freezer 200 to the workers' bodies and also greatly reduce the labor intensity of the workers.

[0096] In addition, during the process of the battery pack entering and exiting the freezer 200, since both the discharge gate 320 and the feed gate 120 are in a closed state, the freezer 200 is isolated from the outside world, which can reduce the influence of external hot air on the internal temperature of the freezer 200 when materials enter and exit the freezer 200. The internal temperature of the freezer 200 is maintained within a preset temperature range, and the existing materials inside the freezer 200 can be cooled normally without being affected by newly added materials.

[0097] It is understood that the battery disassembly system is used to achieve battery disassembly and recycling, and also includes devices for removing the lithium battery casing, high and low voltage wiring harnesses, battery management system, cooling plate, and busbars. After the battery casing, high and low voltage wiring harnesses, battery management system, cooling plate, and busbars are removed, it enters the cooling device for cooling.

[0098] It is understood that the battery packs can be transported to the loading conveyor line by workers using a forklift so that the battery packs can be cooled on the cooling device. In some embodiments, the battery disassembly system also includes a robot for automatically loading the battery packs, which can automatically place the battery packs on the loading conveyor line, further reducing the labor intensity of workers.

[0099] After the battery pack has cooled, it needs to be vibrated from the back to separate the cells from the pack. This process can be accomplished manually. In some embodiments, the battery disassembly system also includes a vibrating station, where a manipulator vibrates the battery pack to automatically separate the cells from the pack, further reducing the workload of workers.

[0100] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
