[0030] The utility model provides a battery module thermal conductive adhesive coating system 1. In one embodiment, Figure 1 and Figure 2As shown, the battery module thermal conductive glue coating system 1 includes a glue pump device 11, a hose assembly 12, a temperature control device 13 and a glue quantitative device 14. The glue pump device 11 includes a first pump assembly 111 and a second pump assembly 112; the hose assembly 12 includes a first hose 121 and a second hose 122; the temperature control device 13 includes a first temperature control assembly 131 and an auxiliary temperature adjustment assembly 132, and the auxiliary temperature adjustment assembly 132 includes a heat exchanger 1321, a water pump 1322, a first sealing box 1323 and a first heat transfer pipe 1324. The heat exchanger 1321 is arranged on the air outlet side of the first pump assembly 111 and the second pump assembly 112. The sealing box and the heat exchanger 1321 are both connected to the first heat transfer pipe 1324. The first heat transfer pipe 1324 contains liquid refrigerant. The water pump 1322 is installed on the first heat transfer pipe 1324. The first sealing box 1323 is provided with A first glue inlet 13231 and a first glue outlet 13232, the first rubber hose 121 includes a first branch pipe 1211 and a second branch pipe 1212, one end of the first branch pipe 1211 is connected to the output end 1421 of the first pump assembly 111, the other end of the first branch pipe 1211 is connected to the first glue inlet 13231, and one end of the second branch pipe 1212 is connected to the first glue outlet 13232; the first temperature control assembly 131 is installed on the second branch pipe 1212, and the first temperature control assembly 131 is used to heat the material in the second branch pipe 1212; the rubber quantitative device 14 includes a first input end 1411, a second input end 1412 and an output end 1421; one end of the second branch pipe 1212 away from the first glue outlet 13232 is connected to the first input end 1411, and the second pump assembly 112 is connected to the second input end 1412 through the second rubber hose 122.

[0031] When the temperature of the thermally conductive adhesive needs to be increased, the first pump assembly 111 extracts the first material from the adhesive barrel and delivers it to the first branch pipe 1211. Heat is generated in the process of the first pump assembly 111 extracting the first material, and part of the heat is blown out by the cooling fan in the first pump assembly 111. Similarly, a large amount of heat is also generated in the process of the second pump assembly 112 extracting the second material from the adhesive barrel, and part of the heat is blown out by the cooling fan in the second pump assembly 112. Since the heat exchanger 1321 is arranged between the first pump assembly 111 and the second pump assembly The air outlet side of the heat exchanger 1321 is formed by the heat exchanger 1321. Therefore, the heat exchanger 1321 can absorb this part of the heat, resulting in an increase in the temperature of the heat exchanger 1321. When the water pump 1322 drives the liquid refrigerant in the first heat transfer tube 1324 to pass through the heat exchanger 1321, the liquid refrigerant absorbs the heat of the heat exchanger 1321 and then moves to the first sealed box 1323 to transfer the heat to the first sealed box 1323. The first sealed box 1323 contains the first material sent into the first sealed box 1323 through the first branch pipe 1211 and the first glue inlet 13231. , the first sealing box 1323 transfers the heat to the first material, thereby preheating the first material. The first material after the temperature is increased enters the second branch pipe 1212 from the second glue outlet 13252, and is then heated by the first temperature control component 131. The first material after the temperature is increased enters the glue quantitative device 14 from the first input end 1411, and the second material enters the glue quantitative device 14 through the second input end 1412. The first material and the second material can only form a thermal conductive adhesive for battery coating after mixing. Therefore, by increasing the temperature of the first material, the temperature of the thermal conductive adhesive is increased. Since the first material heated by the first temperature control component 131 has been preheated, compared with directly heating the first material that has not been preheated, the first temperature control component 131 takes less time and is more efficient to heat the first material to the same temperature. Moreover, since the preheating heat comes from the heat generated when the first pump component 111 and the second pump component 112 are working, less energy is consumed than purely relying on the heater to heat the first material. It should be noted that the first temperature control component 131 can be used not only to heat the material but also to reduce the temperature of the material. The first temperature control component 131 can be implemented by using existing technology.

[0032] In one embodiment, the temperature control device 13 further includes a cooling component 133, the cooling component 133 includes a three-way solenoid valve 1331, a radiator 1332, a first one-way valve 1333 and a connecting pipe 1334, the first heat transfer pipe 1324 includes a first pipe body 13241, a second pipe body 13242, a third pipe body 13243 and a fourth pipe body 13244 that are connected in sequence, the first pipe body 13241 is connected to the heat exchanger 1321, and the third pipe body 13243 is connected to the fourth pipe body 13244. The first sealing box 1323 is connected, the three-way solenoid valve 1331 is installed on the fourth tube body 13244, one end of the connecting tube 1334 is connected to the three-way solenoid valve 1331, and the other end of the connecting tube 1334 is connected to the second tube body 13242, the radiator 1332 is connected to the connecting tube 1334, and the first one-way valve 1333 is installed on the connecting tube 1334, so that the liquid refrigerant can flow from the fourth tube body 13244 to the second tube body 13242 through the connecting tube 1334. Among them, the three-way solenoid valve 1331 can switch back and forth between the first working mode and the second working mode. When the three-way solenoid valve 1331 is in the first working mode, the liquid refrigerant in the fourth tube 13244 can flow into the first tube 13241 through the three-way solenoid valve 1331, and the liquid refrigerant in the fourth tube 13244 cannot flow into the connecting pipe 1334 through the three-way solenoid valve 1331; when the three-way solenoid valve 1331 is in the second working mode, the liquid refrigerant in the fourth tube 13244 cannot flow into the first tube 13241 through the three-way solenoid valve 1331, and the liquid refrigerant in the fourth tube 13244 can flow into the connecting pipe 1334 through the three-way solenoid valve 1331; when it is necessary to lower the temperature of the thermal conductive adhesive, the three-way solenoid valve 1331 is adjusted to make it Entering the second working mode, the liquid refrigerant in the third tube body 13243 absorbs the heat of the first material in the first sealed box 1323, and then flows into the connecting pipe 1334 through the fourth tube body 13244 and the three-way solenoid valve 1331. The connecting pipe 1334 passes through the radiator 1332 and then transfers the heat to the radiator 1332. The liquid refrigerant with reduced temperature flows through the first one-way valve 1333 and enters the second tube body 13242, and then enters the third tube body 13243 through the water pump 1322, and so on, so as to realize the pre-cooling of the first material in the first sealed box 1323. After the pre-cooling, the first material is cooled by the first temperature control component 131, thereby effectively improving the cooling efficiency of the first material, and then improving the cooling efficiency of the thermal conductive glue. It should be noted that the connection position between the connecting pipe 1334 and the second tube body 13242 is located on one side of the feed end of the water pump 1322, that is, on the left side of the water pump 1322. It should also be noted that the third tube body 13243 can be arranged around the periphery of the first sealed box 1323 , or can be arranged on the bottom of the first sealed box 1323 .

[0033] According to an embodiment of the utility model, the battery module thermal conductive adhesive coating system 1 also includes a second one-way valve 15, which is installed on the second tube body 13242. The second one-way valve 15 is used to prevent the liquid refrigerant flowing out of the connecting tube 1334 from flowing in the direction of the first tube body 13241, that is, moving to the left.

[0034] In one embodiment, the radiator 1332 includes a heat dissipation body and a fan. One side of the heat dissipation body is connected to the connecting pipe 1334, and the other side of the heat dissipation body is provided with a plurality of heat dissipation fins, and the air outlet side of the fan is arranged toward the heat dissipation fins. The liquid refrigerant transfers heat to the heat dissipation body. On the one hand, the heat dissipation body increases the contact area with the air through the heat dissipation fins, thereby transferring the heat to the external environment; on the other hand, the fan can accelerate the air flow rate around the heat dissipation fins, thereby further enhancing the heat exchange efficiency between the heat dissipation fins and the external environment. It should also be noted that even considering the power of the water pump 1322, compared with directly preheating the material with a heating device, the energy consumption of the water pump 1322 is still smaller when the same amount of the first material is raised to the same temperature.

[0035] In one embodiment, the battery module thermal conductive adhesive coating system 1 also includes a temperature detection device (not shown) and a control device 16. The temperature detection device, the first temperature control component 131, the water pump 1322 and the three-way solenoid valve 1331 are all electrically connected to the control device 16, and the temperature detection device is used to detect the ambient temperature. The temperature detection device determines whether the thermal conductive adhesive needs to be heated up or cooled down by detecting the ambient temperature. If neither is required, the control device 16 controls the water pump 1322 to stop running; if the thermal conductive adhesive needs to be heated up, the control device 16 controls the three-way solenoid valve 1331 to switch to the first working mode, the water pump 1322 starts, and the first temperature control component 131 starts; if the thermal conductive adhesive needs to be cooled down, the control device 16 controls the three-way solenoid valve 1331 to switch to the second working mode, the water pump 1322 starts, the fan starts, and the first temperature control component 131 starts.

[0036] In one embodiment, the temperature control device 13 also includes a second temperature control component 134, the auxiliary temperature adjustment component 132 also includes a second sealing box 1325 and a second heat transfer tube 1326, the second sealing box 1325 is provided with a second glue inlet 13251 and a second glue outlet 13252, the second rubber hose 122 includes a third branch pipe 1221 and a fourth branch pipe 1222, one end of the third branch pipe 1221 is connected to the second pump component 112, the other end of the third branch pipe 1221 is connected to the second glue inlet 13251, one end of the fourth branch pipe 1222 is connected to the second glue outlet 13252, the other end of the second branch pipe 1212 is connected to the second input end 1412, and both ends of the second heat transfer tube 1326 are connected to the first heat transfer tube 1324; the second temperature control component 134 is installed on the fourth branch pipe 1222. By providing the second heat transfer tube 1326, the liquid refrigerant can also heat up or cool down the second material in the second sealed box 1325 through the second heat transfer tube 1326. The principle is similar to that of the first material and will not be repeated here. By adding the second sealed box 1325, the second heat transfer tube 1326 and the second temperature control component 134 to control the temperature of the second material, the temperature control efficiency of the thermal conductive adhesive is further improved.

[0037] In one embodiment, the first heat transfer tube 1324 is provided with a first connection port 13245 and a second connection port 13246, and the first connection port 13245 and the second connection port 13246 are respectively provided on both sides of the first sealed box 1323, one end of the second heat transfer tube 1326 is connected to the first connection port 13245, and the other end of the second heat transfer tube 1326 is connected to the second connection port 13246. This arrangement makes the temperature of the liquid refrigerant flowing through the first sealed box 1323 and the temperature of the liquid refrigerant flowing through the second sealed box 1325 almost equal, which can effectively reduce the temperature difference between the first material and the second material, and is more conducive to the subsequent mixing of the first material and the second material. It should be noted that the first interface is located at the discharge end side of the water pump 1322, that is, at the right side of the water pump 1322, and the first interface and the second interface are respectively located on the left and right sides of the first sealed box 1323.

[0038] In one embodiment, the battery module thermal conductive adhesive coating system 1 further includes a barcode scanner (not shown), which can scan the identification code set on the rubber barrel and determine whether the material in the rubber barrel is expired. When the material in the rubber barrel is used up and needs to be replaced, the operator scans the identification code on the rubber barrel to be replaced through the barcode scanner. The barcode scanner can obtain the production date of the material in the rubber barrel through the identification code, and then compare it with the date when it is scanned, so as to determine whether the material in the rubber barrel is expired, so as to avoid the operator using expired materials for production and causing product defects.

[0039] In one embodiment, the battery module thermal conductive adhesive coating system 1 also includes an alarm (not shown), which is electrically connected to the barcode scanner. If the barcode scanner determines that the material in the rubber barrel has expired by scanning the identification code on the rubber barrel, a signal is sent to the alarm, and the alarm sounds an alarm to remind the operator. It should be noted that the barcode scanner and the alarm are both electrically connected to the control device 16. The barcode scanner can send the identified information to the control device 16, which is compared by the control device 16. If it is found that the production date has passed, the alarm is controlled to sound an alarm.

[0040] In one embodiment, the adhesive metering device 14 includes a metering component 141 and a mixer 142. The metering component 141 is provided with a first input end 1411 and a second input end 1412. The mixer 142 is connected to the metering component 141. The mixer 142 is also provided with an output end 1421. The metering component 141 is used to adjust the amount of thermal conductive adhesive flowing out of the output end 1421. In the existing battery thermal conductive adhesive coating, only a specified pump pressure can be set during a coating operation, so that the amount of thermal conductive adhesive coated is fixed and cannot be changed. Since the heat dissipation capacity of different positions of the battery pack is different, the amount of thermal conductive glue required is also different. Some parts need more thermal conductive glue, and some parts need less thermal conductive glue. However, in order to ensure the quality of the battery pack and to meet the glue application amount of more parts, it is often necessary to set the pump pressure to a large amount to increase the amount of thermal conductive glue applied. This will result in excessive thermal conductive glue being applied to parts with less glue, causing unnecessary waste. The amount of thermal conductive glue output is controlled by setting the quantitative component 141, and the glue pressing pressure of the quantitative component 141 is automatically adjusted for different parts of the battery pack, so as to achieve different amounts of thermal conductive glue applied to different parts. It should be noted that the quantitative component 141 and the mixer 142 can be implemented using existing technology. It should also be noted that there are 8 flow channels on the lower shell of the battery, and 8 thermal conductive adhesives need to be applied. Since the 1st to 7th flow channels of the lower shell are supported by corresponding reinforcing ribs, and the 8th flow channel has no reinforcing ribs in design, the plane of the 8th flow channel of the lower shell sinks during splicing, resulting in the need to increase the amount of thermal conductive adhesive applied to meet the heat dissipation effect. The existing method of applying glue is that the thermal conductive adhesive of the first 8 flow channels needs to be increased, which causes unnecessary waste of the other 7 glues, resulting in an increase in the amount of glue applied and the cost of a single battery. According to the thermal conductive adhesive of 0.093 yuan per cubic centimeter, the cost of a single battery pack is: 0.093 yuan / cm 3 ×2477cm 3= 230.361 yuan / unit. If 290 battery packs are produced per month, the total monthly cost is: 290 units / month × 230.361 yuan / unit = 66,804.69 yuan / month. The total annual cost is: 66,804.69 yuan / month × 12 months = 801,656.28 yuan / year. After using the glue metering device 14 for glue coating, the glue coating system can automatically adjust the glue pressing pressure of the metering machine for different parts of the battery pack during one glue coating operation to achieve different amounts of thermal conductive glue coating on different parts. Only the glue coating amount of the 8th glue is increased, and the original glue coating amount of the other 7 glues remains unchanged. Thereby, the glue coating amount of a single battery pack is reduced to 2001cm 3 , the glue coating amount decreased by 476cm 3 , and does not affect product quality, based on 290 units / month, monthly cost: 290 units / month×2001cm 3 ×0.093cm 3 / yuan = 53966.97 yuan / month. Monthly cost savings: (66804.69-53966.97) yuan / month = 12837.72 yuan / month, annual savings: 12837.72 yuan / month × 12 months = 154052.64 yuan / year.

[0041] According to an embodiment of the utility model, the battery module thermal conductive adhesive coating system 1 also includes a glue coating detection module and a glue barrel detection module, both of which are electrically connected to the control device 16. The glue coating detection module is used to detect the glue coating pressure, glue coating flow rate and glue coating shape; the glue barrel detection module is used to detect the remaining amount of glue in the glue barrel. If there is an abnormality, an alarm is issued, thereby effectively ensuring the coating quality of the thermal conductive adhesive.

[0042] According to another embodiment of the utility model, the battery module thermal conductive adhesive coating system 1 further includes a mechanical arm, which is connected to the quantitative component 141 and is used to drive the mixer 142 to move through the quantitative component 141. It should be noted that the quantitative component 141 includes a quantitative system and a quantitative machine.

[0043] In one embodiment, the first pump assembly 111 includes a first glue pump 1111 and a second glue pump 1112, and the first glue pump 1111 and the second glue pump 1112 are both connected to the first rubber hose 121. By providing the first glue pump 1111 and the second glue pump 1112, when the first glue pump 1111 is working, the glue barrel can be placed at the second glue pump 1112 in advance, and when the first glue pump 1111 completes the extraction operation, the second glue pump 1112 can directly extract the material in the pre-placed glue barrel, thereby avoiding the phenomenon of reduced production efficiency caused by replacing the glue barrel.

[0044] According to an embodiment of the present invention, the second pump assembly 112 includes a third glue pump 1121 and a fourth glue pump 1122 , and the third glue pump 1121 and the fourth glue pump 1122 are both connected to the second rubber hose 122 .

All equivalent structural changes made based on the concept of the utility model and the contents of the description and drawings of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
